Detailed Description
As shown in FIG. 1, the yarn knitting method comprises a step S100 of deforming a first warp yarn extending along a first direction and forming the first warp yarn into a wave shape, a step S200 of deforming a second warp yarn extending along the first direction and forming the second warp yarn into a wave shape, a step S300 of forming a plurality of perforations between the first warp yarn and the second warp yarn, wherein the openings of the perforations are oriented perpendicular to the first direction, and a step S400 of simultaneously inserting a plurality of weft yarns extending along the second direction into the perforations to form a fabric, wherein the first warp yarn and the second warp yarn are alternately distributed. It should be understood that, in some embodiments, the step S100 and the step S200 are performed simultaneously, specifically, the step S100 and the step S200 are implemented simultaneously by the wire spreader 1, which will be described later in the specification. However, in some embodiments, step S100 and step S200 may be implemented separately, e.g., step S200 may precede step S100, and the disclosure is not particularly limited.
For easy understanding of the above-described thread braiding method, please refer to fig. 3-7. Specifically, as shown in fig. 4, the first clamping device 87 and the second clamping device 88 clamp the first warp yarn 21 and the second warp yarn 22, and a yarn opening device 1 is disposed between the first clamping device 87 and the second clamping device 88, the yarn opening device 1 is used for opening the first warp yarn 21 and the second warp yarn 22 to form a wave shape for the first warp yarn 21 and the second warp yarn 22, and the first warp yarn 21 and the second warp yarn 22 are staggered to form a plurality of perforations. And a plurality of wefts 23 pass through the perforations simultaneously under the drive of the weft feeding device 5 to form the fabric 9 in cooperation with the first warp threads 21 and the second warp threads 22. In particular, how to implement the above steps by the thread opening device 1 and the weft thread feeding device 5 will be described in the following description.
Further, as shown in fig. 3, the weft feeding device 5 is located at one side (i.e., right side) of the first warp 21 and the second warp 22 and holds the weft 23. Thereafter, the weft feeding device 5 drives the weft 23 to move from one side (right side) of the first warp 21 and the second warp 22 to the other side (left side) of the first warp 21 and the second warp 22 so that the weft 23 passes through the perforation formed by the first warp 21 and the second warp 22. Meanwhile, the ends of the weft yarn 23 passing through the first warp yarn 21 and the second warp yarn 22 (i.e., the left ends of the weft yarn 23 in fig. 4) are fixed, and at this time, the weft yarn feeding device 5 may return to one side (right side) of the first warp yarn 21 and the second warp yarn 22 to clamp the weft yarn 23, as shown in fig. 4. It will be appreciated that if the weft thread 23 is not cut, it is necessary to be affected by the weft thread feeding device 5 when the pitch of the weft thread 23 is subsequently adjusted. In some embodiments, step S500 is also included to cut the weft. In particular cutting the weft thread 23 such that a portion of the weft thread 23 passing through the perforation is separated from another portion not passing through the perforation and being gripped by the weft thread feeding device 5, as shown in fig. 5. At this time, one end of the weft yarn 23 which does not pass through the perforation is still clamped by the weft yarn feeding device 5, so that the subsequent weft yarn feeding device 5 can conveniently pass the weft yarn 23 of the part through the perforation formed by the cooperation of the first warp yarn 21 and the second warp yarn 22.
Since the different fabrics 9 have different requirements for the pitch of the wefts 23, as shown in fig. 2, a step S600 is further included in some embodiments, to adjust the pitch between the wefts 23 to a preset value. Specifically, the spacing between the wefts 23 is adjusted to a preset value by the wire unwinding device 1, and a detailed description will be described in the following specification. However, in some embodiments, other means may be provided or the spacing between the wefts 23 may be manually adjusted to a preset value, and the present disclosure is not particularly limited.
And S700, folding the fabric in half to a preset shape and sealing edges. Among them, the preset shape is various, such as a cuboid, a hemispherical shape, etc., and the present disclosure is not particularly limited. Edge sealing refers to stitching the edges of the fabric 9 (i.e., the breaks in the first warp yarn 21, the second warp yarn 22, or the weft yarn 23 at the edges) so that the edges interweave together to allow the fabric 9 to take on a pre-set shape without further unraveling. It should be appreciated that in order to achieve folding and banding of the fabric 9, the present disclosure further includes a folding device 84 to fold the fabric 9 in half and a banding device 86 to banding the fabric 9, and the present disclosure is not limited in this respect as the folding device 84 and banding device 86 are various.
Step S800, cutting the fabric 9.
In step S900, after the fabric 9 is cut, one of the first clamping device 87 and the second clamping device 88 clamps the first warp yarn 21 and the second warp yarn 22 to move to the second clamping position, and the other of the first clamping device 87 and the second clamping device 88 unclamps the first warp yarn 21 and the second warp yarn 22, moves between the first clamping device 87 and the yarn feeding device 81, clamps the first warp yarn 21 and the second warp yarn 22, and moves to the first clamping position. While it should be understood that the weaving system further comprises cutting means 85, the cutting means 85 being used for cutting the fabric 9. In some embodiments, the device further comprises a chain riveting device 89, wherein the chain riveting device 89 is provided with a series of chain riveting, and the chain riveting is inserted into holes of the fabric 9 to fix the fabric 9, so that the fabric 9 is prevented from being greatly deformed due to stress when being cut.
As can be seen from fig. 4, the entire wire knitting system includes a wire feeding device 81, a first clamping device 87 and a second clamping device 88. The thread supplying device 81 is a device for providing the first warp thread 21 and the second warp thread 22, which may be a device for producing the first warp thread 21 and the second warp thread 22 or a device for storing the first warp thread 21 and the second warp thread 22, and the present disclosure is not particularly limited. The first clamping device 87 and the second clamping device 88 are used for clamping the first warp yarn 21 and the second warp yarn 22 so as to tighten the first warp yarn 21 and the second warp yarn 22 between the first clamping device 87 and the second clamping device 88, thereby facilitating the subsequent weaving of the fabric 9. In some embodiments, referring to fig. 8 and 9, the first clamping device 87 includes a first mounting bracket 871, a plurality of first clamping piece driving devices 873, and a plurality of first clamping pieces 872, the first clamping piece driving devices 873 are mounted on the first mounting bracket 871, the first clamping pieces 872 are in one-to-one correspondence with the first clamping piece driving devices 873, and the first clamping piece driving devices 873 are used for driving the first clamping pieces 872 corresponding thereto to move, and the first clamping pieces 872 are used for clamping the first warp threads 21 and the second warp threads 22. Specifically, the first clamping bracket 871 is disposed above the first warp yarn 21 and the second warp yarn 22, and when the first clamping member driving device 873 drives the first clamping member 872 to move downward to the position shown in fig. 9, the first clamping member 872 can contact the first warp yarn 21 and the second warp yarn 22 and can clamp the first warp yarn 21 and the second warp yarn 22. In some embodiments, a first clamping drive may be provided to drive the first clamping member 872 open and close to effect clamping or unclamping of the first warp yarn 21 and the second warp yarn 22. When the first clamping member driving device 873 drives the clamping member to move upward to the position shown in fig. 8, the first clamping member 872 cannot touch the first warp yarn 21, the second warp yarn 22 and the weft yarn 23, so that the first clamping device 87 can be prevented from touching the first warp yarn 21, the second warp yarn 22 and the weft yarn 23 when moving from the second clamping position to the front of the first clamping position. In some embodiments, referring to fig. 10 and 11, the second clamping device 88 includes a second clamping bracket 881, a plurality of second clamping member driving devices 883, and a plurality of second clamping members 882, the second clamping member driving devices 883 are mounted on the second clamping bracket 881, the second clamping members 882 are in one-to-one correspondence with the second clamping member driving devices 883, and the second clamping member driving devices 883 are used for driving the second clamping members 882 corresponding thereto to move, and the second clamping members 882 are used for clamping the first warp threads 21 and the second warp threads 22. specifically, the second clamping bracket 881 is disposed below the first warp yarn 21 and the second warp yarn 22, and when the second clamping member driving device 883 drives the second clamping member 882 to move upward to the position shown in fig. 11, the second clamping member 882 can contact the first warp yarn 21 and the second warp yarn 22 and can clamp the first warp yarn 21 and the second warp yarn 22. When the second gripper driving device 883 drives the second gripper 882 to move downward to the position shown in fig. 10, the second gripper 882 cannot touch the first warp yarn 21, the second warp yarn 22, and the weft yarn 23.
In some embodiments, a retraction device 82 may be further included, where the retraction device 82 is configured to control retraction of the first warp yarn 21 and the second warp yarn 22.
With continued reference to fig. 4, one ends of the first warp yarn 21 and the second warp yarn 22 are located in the yarn feeding device 81, and the first clamping device 87 and the second clamping device 88 are located at a first clamping position and a second clamping position, respectively, wherein the first clamping position is located between the yarn feeding device 81 and the second clamping position. When cutting the fabric 9, as shown in fig. 5, in addition to the first warp yarn 21 and the second warp yarn 22 positioned before the second clamping device 88 are cut, the first warp yarn 21 and the second warp yarn 22 positioned behind the first clamping position are also cut. At this time, the second clamping device 88 releases the first warp yarn 21 and the second warp yarn 22 to move in front of the first clamping device 87 (first clamping position), and clamps the first warp yarn 21 and the second warp yarn 22 between the first clamping device 87 and the yarn feeding device 81, as shown in fig. 6. Then, the first clamping device 87 moves forward to the second clamping position, and the second clamping device 88 moves forward to the first clamping position, as shown in fig. 7. It will be appreciated that the first clamping device 87 in the first clamping position needs to be moved forward away from the first clamping position before the second clamping device 88 between the first clamping position and the wire feeding device 81 is moved to the first clamping position. This prevents the first clamping device 87 and the second clamping device 88 from colliding with each other when they are simultaneously in the first clamping position.
Similarly, when the fabric 9 is cut and the first clamping device 87 is located at the second clamping position and the second clamping device 88 is located at the first clamping position, the first clamping device 87 releases the first warp yarn 21 and the second warp yarn 22 to move in front of the second clamping device 88 (the first clamping position) and clamps the first warp yarn 21 and the second warp yarn 22 located between the second clamping device 88 and the yarn feeding device 81. Then, the first clamping device 87 and the second clamping device 88 are moved forward simultaneously, but the first clamping device 87 is stopped when moved to the first clamping position, and the second clamping device 88 is moved to the second clamping position.
It will be appreciated that the first warp yarn 21 extends forward in the direction of extension near the yarn feeding device 81 and rearward in the direction of the second clamping position.
Optionally, a beam-shrinking device 83 is disposed between the wire-supplying device 81 and the first clamping position, and the beam-shrinking device 83 is used for adjusting the orientation and the position of the first warp yarn 21 and the second warp yarn 22, so that the first warp yarn 21 and the second warp yarn 22 are arranged at a preset interval. And if the first clamping device 87 is located at the first clamping position after cutting the fabric 9, the first warp threads 21 and the second warp threads 22 located between the beam-receiving device 83 and the first clamping device 87 can be arranged according to a preset mode through the cooperation of the beam-receiving device 83 and the first clamping device 87, so that when the second clamping device 88 moves between the first clamping device 87 and the beam-receiving device 83, the first warp threads 21 and the second warp threads 22 located between the first clamping device 87 and the beam-receiving device 83 can be clamped quickly. Similarly, if the second clamping device 88 is located at the first clamping position after the fabric 9 is cut, the first warp threads 21 and the second warp threads 22 located between the beam-receiving device 83 and the second clamping device 88 can be arranged according to a preset manner by matching the beam-receiving device 83 and the second clamping device 88. It is possible to clamp the first warp yarn 21 and the second warp yarn 22 between the second clamping device 88 and the converging device 83 quickly when the first clamping device 87 moves between the second clamping device 88 and the converging device 83. It should be understood that, although the arrangement of the first warp yarn 21 and the second warp yarn 22 is adjusted by the beam shrinking device 83 in the above embodiment, in some embodiments, the first warp yarn 21 and the second warp yarn 22 may be arranged in a preset manner by properly arranging the yarn feeding device 81, and specifically, the first warp yarn 21 and the second warp yarn 22 between the yarn feeding device 81 and the first clamping device 87 and the second clamping device 88 extend along the first direction.
By the method, the other ends of the first warp yarn 21 and the second warp yarn 22 after the fabric 9 is cut are always clamped by the first clamping device 87 or the second clamping device 88, so that the problem that the first warp yarn 21 and the second warp yarn 22 need to be mounted to the first clamping device 87 or the second clamping device 88 again after each time the fabric 9 is cut is avoided.
Alternatively, the forage is made into the first warp yarn 21, the second warp yarn 22, and the weft yarn 23.
For ordinary spinning, the raw material is natural or chemical fiber. Natural fibers such as cotton, hemp, silk, wool, etc. Wherein the fiber is a relatively flexible, thin, long material having an aspect ratio generally greater than 1000:1. Typical textile fibres have diameters of a few microns to tens of microns, lengths exceeding 25mm and linear densities on the order of 10-5 g/mm. The yarn diameter is generally about 0.13-0.28 mm, and the yarn made of chemical fibers is finer. The first warp yarn 21, the second warp yarn 22 and the weft yarn 23 of the present disclosure are made of forage, and the weaving rope of a general machine with the diameter of about 0.5-1.5 mm is generally larger than 2mm and thicker. The first warp thread 21 and the second warp thread 22 can be advantageously waved by mechanical means (thread-spreading means) to form a plurality of perforations simultaneously for the passage of the weft thread 23.
For a better description of the wire distraction device 1, refer to fig. 12a, 12b and 12c, which include a plurality of first wire deforming structures 11 and a plurality of second wire deforming structures 12, the first wire deforming structures 11 are pressed against the first warp threads 21 to deform the first warp threads 21, and the second wire deforming structures 12 are pressed against the second warp threads 22 to deform the second warp threads 22. As shown in fig. 12b and 12d, the first thread deformation structures 11 and the second thread deformation structures 12 are alternately distributed along the first direction a so that the first warp threads 21 and the second warp threads 22 are alternately distributed along the first direction a. As can be seen in fig. 14b, 14c and 14d, the first thread deformation structure 11 and the second thread deformation structure 12 cooperate to form a plurality of perforations 24 between the first warp threads 21 and the second warp threads 22. And the perforation 24 is used to pass the weft yarn 23, and the first warp yarn 21 and the second warp yarn 22 sandwich the weft yarn 23 in a state where the first warp yarn 21 and the second warp yarn 22 are tensioned. Referring to fig. 12e, the first line deforming structure 11 includes a plurality of first abutting structures 111 distributed along the second direction B, and a plurality of second abutting structures 112 distributed along the second direction B.
Fig. 14b is a schematic side view of a structure corresponding to the first line deformation structure shown in fig. 13 b. Fig. 14c is a schematic side view of a structure corresponding to the second line deformation structure shown in fig. 13 d. Fig. 14d is a schematic view of the structure when the first wire deformation structure shown in fig. 14b and the second wire deformation structure shown in fig. 14c are mated. As shown in fig. 14B, the first abutting structure 111 abuts against the first warp yarn 21 so that the portion of the first warp yarn 21 abutting against the first abutting structure 111 protrudes in the third direction C, the second abutting structure 112 abuts against the first warp yarn 21 so that the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrudes in the opposite direction of the third direction C, and the first abutting structure 111 and the second abutting structure 112 are alternately distributed along the second direction B so that the first warp yarn 21 is wavy. As shown in fig. 14C, the second thread deformation structure 12 includes a plurality of third abutting structures 123 and a plurality of fourth abutting structures 124, the third abutting structures 123 are abutted against the second warp threads 22 to make the second warp threads 22 protrude along the third direction C, the fourth abutting structures 124 are abutted against the second warp threads 22 to make the second warp threads 22 protrude along the opposite direction of the third direction C, and the third abutting structures 123 and the fourth abutting structures 124 are alternately distributed along the second direction B to make the second warp threads 22 wavy. However, since the waves formed by the first warp yarn 21 and the waves formed by the second warp yarn 22 are staggered, as shown in fig. 14d, the perforations 24 can be observed when the first warp yarn 21 and the second warp yarn 22 are viewed along the first direction a.
Wherein both ends of the first warp yarn 21 are forced to be tensioned in the second direction B. The second warp yarn 22 is forced to be tensioned in the second direction B at both ends, and the third direction C is perpendicular to the second direction B.
It should be understood that the tensioning is merely indicative of an action, and the tensioned threads (threads referring to the first warp thread 21, the second warp thread 22 and the weft thread 23) do not necessarily have to be straight, but may merely be a stepwise straight-like change from the original wavy form. The first warp yarn 21 being pulled in the second direction B means that both ends of the first warp yarn 21 are respectively subjected to forces in the second direction B and in a direction opposite to the second direction B, so that the first warp yarn 21 becomes extended in the second direction B. The second warp yarn 22 being pulled in the second direction B means that both ends of the second warp yarn 22 are respectively subjected to forces in the second direction B and in a direction opposite to the second direction B, so that the second warp yarn 22 becomes extended in the second direction B. Taking the first warp yarn 21 as an example, referring to fig. 14a, it is shown that the first warp yarn 21 is subjected to a first external force N extending in the second direction B and a second external force M extending in the opposite direction of the second direction B. The projections of the application points of the first external force N and the second external force M on the cross section are located at the same point, so that the first warp yarn 21 is tensioned along the second direction B under the action of the first external force N and the second external force M only, and extends along the second direction B. Wherein the cross section is perpendicular to the second direction B. More specifically, the third direction C is vertically upward, the opposite direction of the third direction C is vertically downward, the heights of the points of the first warp yarn 21 are uniform when the first warp yarn 21 extends in the second direction B, and the heights of the points of the second warp yarn 22 are uniform when the second warp yarn 22 extends in the second direction B.
When the first abutting structure 111 abuts against the first warp yarn 21 to make the first warp yarn 21 protrude in the third direction C, and the second abutting structure 112 abuts against the first warp yarn 21 to make the first warp yarn 21 protrude in the opposite direction to the third direction C, as shown in fig. 13b, the first abutting structure 111 is located below the first warp yarn 21 to push up the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the first abutting structure 111 protrude upward, and the second abutting structure 112 is located above the first warp yarn 21 to push up the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrude downward, so that the first warp yarn 21 is in a wave shape as shown in fig. 13b by the alternating arrangement of the first abutting structure 111 and the second abutting structure 112.
Specifically, as shown in fig. 15a and 15b, the first abutting structure 111 includes a first driving device 1111, a second driving device 1112, a first abutting piece 1113, and a second abutting piece 1114. The first drive 1111 drives the first abutment 1113 between a first abutment position and a first distal position, and the second drive 1112 drives the second abutment 1114 between a second abutment position and a second distal position. When the first abutment 1113 is in the first abutment position, as shown in fig. 15b and 13b, the first abutment 1113 protrudes upward, and the first abutment 1113 can press against the first warp yarn 21.
When the second abutment 1114 is in the second abutment position, as shown in fig. 13b and 15b, the second abutment 1114 protrudes upwards, the second abutment 1114 presses against the first warp yarn 21. When the first abutting member 1113 is at the first abutting position and the second abutting member 1114 is at the second abutting position, as shown in fig. 15b and 13b, the first abutting member 1113 and the second abutting member 1114 form a first groove 1115, the first warp 21 is located in the first groove 1115, and the first abutting member 1113 and the second abutting member 1114 are pressed against the first warp 21 to make the first contact portion 211 protrude toward the third direction C, wherein the first contact portion 211 is a portion of the first warp 21 abutting against the first abutting member 1113 and the second abutting member 1114. The first contact portion 211 refers more precisely to a portion where the first warp yarn 21 abuts against the first abutting structure 111 when the first abutting structure 111 abuts against the first warp yarn 21 upward.
Alternatively, as shown in fig. 16a, the second abutment structure 112 includes a third driving device 1121, a fourth driving device 1122, a third abutment 1123, and a fourth abutment 1124.

When the third abutting piece 1123 is at the third abutting position and the fourth abutting piece 1124 is at the fourth abutting position, the third abutting piece 1123 and the fourth abutting piece 1124 form a second groove 1125, the first warp yarn 21 is located in the second groove 1125, and the third abutting piece 1123 and the fourth abutting piece 1124 are abutted against the first warp yarn 21 so that the second contact portion 212 protrudes in the opposite direction (downward in some embodiments) of the third direction C, wherein the second contact portion 212 is a portion when the first warp yarn 21 abuts against the third abutting piece 1123 and the fourth abutting piece 1124. The second contact portion 212 refers more precisely to a portion where the first warp yarn 21 abuts against the second abutting structure 112 when the second abutting structure 112 presses down against the first warp yarn 21.
Alternatively, as shown in fig. 15c and 15d, the third abutting structure 123 includes a fifth driving device 1231, a sixth driving device 1232, a fifth abutting piece 1233, and a sixth abutting piece 1234, where the fifth driving device 1231 drives the fifth abutting piece 1233 to move between a fifth abutting position and a fifth distant position, and the sixth driving device 1232 drives the sixth abutting piece 1234 to move between the sixth abutting position and the sixth distant position. As shown in fig. 13d and 15d, when the fifth abutting element 1233 is at the fifth abutting position and the sixth abutting element 1234 is at the sixth abutting position, the fifth abutting element 1233 and the sixth abutting element 1234 form a third groove 1235, the second warp 22 is located in the third groove 1235, and the fifth abutting element 1233 and the sixth abutting element 1234 are pressed against the second warp 22 so as to make the third contact portion 213 protrude in the third direction C, wherein the third contact portion 213 is a portion of the second warp 22 abutting against the fifth abutting element 1233 and the sixth abutting element 1234. The third contact portion 213 refers more precisely to a portion where the second warp yarn 22 abuts against the third abutting structure 123 when the third abutting structure 123 abuts against the second warp yarn 22 upward.
Alternatively, as shown in fig. 16C and 16d, the fourth abutting structure 124 includes a seventh driving device 1241, an eighth driving device 1242, a seventh abutting piece 1243 and an eighth abutting piece 1244, the seventh driving device 1241 drives the seventh abutting piece 1243 to move between a seventh abutting position and a seventh distant position, the eighth driving device 1242 drives the eighth abutting piece 1244 to move between the eighth abutting position and the eighth distant position, and when the seventh abutting piece 1243 is in the seventh abutting position and the eighth abutting piece 1244 is in the eighth abutting position, the seventh abutting piece 1243 and the eighth abutting piece 1244 form a fourth groove 1245, the second warp thread 22 is located in the fourth groove 1245 and the seventh abutting piece 1243 and the eighth abutting piece 1244 abut against the second warp thread 22 to make the fourth contact portion 214 protrude in the opposite direction of the third direction C, wherein the fourth contact portion 214 is a portion of the second warp thread 22 abutting the seventh abutting piece 1243 and the eighth abutting piece 1244. The fourth contact portion 214 more precisely refers to the portion of the second warp yarn 22 that abuts against the fourth abutment structure 124 when the fourth abutment structure 124 presses down against the second warp yarn 22.
Since both ends of the first warp yarn 21 are tensioned by the external force during the spinning process, both ends of the second warp yarn 22 are tensioned by the external force, if the first warp yarn 21 or the second warp yarn 22 is simply pressed against, both the first warp yarn 21 and the second warp yarn 22 may be tensioned by the external force, so that the first warp yarn 21 and the second warp yarn 22 are difficult to form a wave shape, and the first abutting structure 111 and the second abutting structure 112 respectively pass through the first groove 1115 and the second groove 1125 to limit the first warp yarn 21 to prevent the first warp yarn 21 from separating from the first groove 1115 or the second groove 1125, so that the first warp yarn 21 cannot form a wave shape. Similarly, the third abutting structure 123 and the fourth abutting structure 124 limit the second warp yarn 22 by respectively engaging with the fourth groove 1245 to prevent the second warp yarn 22 from being separated from the third groove 1235 or the fourth groove 1245, so that the second warp yarn 22 cannot form a wave shape.
Alternatively, as shown in fig. 12g, 13a, 15e and 16e, when the first abutting piece 1113 is at the first distant position or the second abutting piece 1114 is at the second distant position, the first abutting piece 1113 and the second abutting piece 1114 cannot form the first groove 1115, the portion of the first warp yarn 21 located in the first groove 1115 slides down under the action of external force so that the first warp yarn 21 is not pressed upwards any more, and when the third abutting piece 1123 is at the third distant position or the fourth abutting piece 1124 is at the fourth distant position, the third abutting piece 1123 and the fourth abutting piece 1124 cannot cooperate to form the second groove 1125, and the portion of the first warp yarn 21 located in the second groove 1125 slides upwards under the action of external force so that the second abutting piece 112 does not press the first warp yarn 21 downwards any more, so that the first warp yarn 21 is tensioned from the wavy shape shown in fig. 13b to the wavy shape shown in fig. 13 a.
Alternatively, as shown in fig. 12g, 13c, 15f and 16f, when the fifth abutment 1233 is at the fifth distant position or the sixth abutment 1234 is at the sixth distant position, the fifth abutment 1233 and the sixth abutment 1234 cannot cooperate to form the third groove 1235, and the portion of the second warp yarn 22 located in the third groove 1235 slides down under the action of external force, so that the third abutment structure 123 no longer presses the second warp yarn 22 upwards. When the seventh abutting element 1243 is at the seventh distant position or the eighth abutting element 1244 is at the eighth distant position, the seventh abutting element 1243 and the eighth abutting element 1244 cannot cooperate to form the fourth groove 1245, and the portion of the second warp yarn 22 located in the fourth groove 1245 slides upwards under the action of the external force, so that the fourth abutting structure 124 does not press the second warp yarn 22 downwards any more, and the first warp yarn 21 is tensioned from the wave shape shown in fig. 13d to the shape shown in fig. 13 c.
It should be appreciated that the first abutment 1113 is in the first, distal position with a top having a lower height than the top of the first abutment 1113 when in the first, abutment position, such that the first abutment 1113 cannot contact the first warp yarn 21 to jack the first warp yarn 21 upwardly, and, similarly, when the second abutment 1114 is in the second, distal position, the top of the second abutment 1114 is lower than the top of the second abutment 1114 when in the second, abutment position, such that the second abutment 1114 cannot contact the first warp yarn 21 to jack the first warp yarn 21 upwardly. Meanwhile, only when the first abutting piece 1113 is at the first abutting position and the second abutting piece 1114 is at the second abutting position, the first warp thread 21 can be limited in the first groove 1115 formed by the first abutting piece 1113 and the second abutting piece 1114, so as to limit the first warp thread 21 to protrude upwards, as shown in fig. 13b, 15b and 16 b. Once the first abutment 1113 is in the first away position or the second abutment 1114 is in the second away position, the first contact portion 211 of the first warp yarn 21 is pulled taut by the first external force N and the second external force M such that the first warp yarn 21 extends substantially in the second direction B, as can be seen in fig. 13a. Similarly, when the third abutting piece 1123 is at the third distant position, the bottom of the third abutting piece 1123 is located at a position higher than the height of the bottom of the third abutting piece 1123 when the third abutting piece 1123 is at the third abutting position, and at this time, the third abutting piece 1123 cannot contact the first warp yarn 21 to bulge the first warp yarn 21 downward. When the fourth abutment 1124 is in the fourth distant position, the bottom of the fourth abutment 1124 is located at a higher level than the bottom of the fourth abutment 1124 when the fourth abutment 1124 is in the fourth abutment position, at which time the fourth abutment 1124 cannot contact the first warp yarn 21 to project the first warp yarn 21 downward. Bringing the third abutment 1123 in the third distal position or the fourth abutment 1124 in the fourth distal position results in the second contact portion 212 of the first warp yarn 21 being pulled taut by the first external force N and the second external force M such that the first warp yarn 21 extends generally in the second direction B, as can be seen in fig. 13a. It should be appreciated that the first warp thread 21 can be restrained in the second groove 1125 formed by the third and fourth abutments 1123, 1124 so as to allow the second contact portion 212 to protrude downward only when the third and fourth abutments 1123, 1124 are in the third and fourth abutment positions. When the fifth abutment 1233 is in the fifth distal position, it is at a position lower than the position at which it is in the fifth abutment position, at which time the fifth abutment 1233 cannot contact the first warp yarn 21 to jack up the first warp yarn 21, and similarly, when the sixth abutment 1234 is in the sixth distal position, it is at a position lower than the position at which it is in the sixth abutment position, at which time the sixth abutment 1234 cannot contact the first warp yarn 21 to jack up the first warp yarn 21. Meanwhile, only when the fifth abutment 1233 is at the fifth abutment position and the sixth abutment 1234 is at the sixth abutment position, the first warp yarn 21 can be restrained in the third groove 1235 formed by the fifth abutment 1233 and the sixth abutment 1234 to restrain the first warp yarn 21 from protruding upward. Similarly, when the seventh abutment 1243 is in the seventh away position, the bottom thereof is located at a higher level than the bottom thereof when the seventh abutment 1243 is in the seventh abutment position, and at this time, the seventh abutment 1243 cannot contact the second warp yarn 22 to downwardly bulge the second warp yarn 22. When the eighth abutment 1244 is in the eighth distant position, the bottom of the eighth abutment 1244 is located higher than the bottom of the eighth abutment 1244 when it is in the eighth abutment position, and at this time, the eighth abutment 1244 cannot contact the second warp yarn 22 to project the second warp yarn 22 downward. Meanwhile, only when the seventh abutment 1243 is at the seventh abutment position and the eighth abutment 1244 is at the eighth abutment position, the second warp thread 22 can be restrained in the fourth groove 1245 formed by the seventh abutment 1243 and the eighth abutment 1244 to restrain the second warp thread 22 from protruding downward. Once the seventh abutment 1243 is in the seventh distal position or the eighth abutment 1244 is in the eighth distal position, the fourth abutment structure 124 cannot press down against the first warp yarn 21 any more.
While in some embodiments the weft thread feeding device 5 comprises a plurality of third clamping members 53, the third clamping members 53 being adapted to clamp the weft thread 23. The plurality of third clamping members 53 drive the weft yarn 23 to move synchronously, and in particular, the plurality of third clamping members 53 may be connected to each other, and the weft yarn 23 is driven to move synchronously together by the third clamping members 53 connected to each other.
Specifically, as shown in fig. 19a, 19b and 19c, the third clamping member 53 includes a clamping body 531 and a plurality of clamping pieces 532, the plurality of clamping bodies 531 are connected to allow the plurality of third clamping members 53 to be connected to each other, one end of the clamping piece 532 is connected to the clamping body 531, the other ends of the plurality of clamping pieces 532 are close to each other to clamp the weft yarn 23, a gap exists between the plurality of clamping pieces 532, and the weft yarn 23 is moved in one direction by the plurality of clamping pieces 532 being engaged. Specifically, the other ends of the plurality of holding pieces 532 are brought close to each other to form a holding port 55 to hold the weft yarn 23. The width w of the clamping piece becomes gradually smaller from one end of the clamping piece 532 to the other end of the clamping piece 532, so that a gap may exist between the clamping pieces 532. In some embodiments, as can be seen from fig. 18b and 19a, the third clamping member 53 includes a clamping main body 531, one end of the clamping main body 531 is provided with a clamping head 54, a clamping piece 532 is disposed on the clamping head 54, one end of the clamping piece 532 is connected to the clamping head 54, and the other ends of the clamping pieces 532 are close to each other to clamp the weft yarn 23. It should be appreciated that the structure of the clamping body 531 may be adapted as appropriate, as in some embodiments the clamping tab 532 is directly connected to the clamping body 531 without the need for a separate clamping head.
To better explain the effect of the clamping piece 532, referring to fig. 19b, when the weft yarn 23 moves from the left to the right in fig. 19b, the other end (right end in fig. 19 b) of the clamping piece 532 is dragged to move to the right, and the clamping opening 55 is further enlarged, so that the resistance force applied to the yarn is small when the yarn moves along one end (left end in the drawing) of the clamping piece 532 to the other end (right end in the drawing) of the clamping piece 532. However, when the weft yarn 23 moves along the other end (right end in the drawing) of the holding piece 532 toward one end (left end in the drawing) of the holding piece 532 (i.e., from right to left in fig. 19 b), the other end of the third holding piece 53 is driven to move to the left, so that the holding opening is narrowed, and the weft yarn 23 is restricted from passing. The plurality of clamping pieces 532 cooperate to enable the weft yarn 23 to pass through the third clamping member 53 only in one direction, so that the weft yarn 23 is prevented from being pulled by force when the third clamping member 53 moves, and the weft yarn 23 is prevented from being separated from the third clamping member 53. Specifically, the clamping main body 531 and the clamping piece 532 move in the opposite direction of the first direction a to pass the weft yarn 23 located in the clamping main body 531 through the through hole 24, and referring to fig. 19b again, it can be seen that, during the process of moving the weft yarn 23 by the plurality of clamping pieces 532, the weft yarn 23 tends to move in the first direction a to separate from the possibility of clamping by the plurality of clamping pieces 532, but since the plurality of clamping pieces 532 restrict the weft yarn 23 to move only in the opposite direction of the first direction a relative to the clamping pieces 532, the weft yarn 23 cannot separate from the clamping by the plurality of clamping pieces 532, so that the weft yarn 23 cannot be separated from the third clamping piece 53.
Also as shown in fig. 18a and 18b, in order to facilitate uniform movement of the third clamping member 53, in some embodiments, the weft in-feeding device 5 further includes a second bracket 52, and the third clamping member 53 is slidably disposed in the second bracket 52 and moves in the first direction a and the opposite direction of the first direction a with respect to the second bracket 52. Optionally, a stop structure 51 is provided on the second bracket 52 to limit the sliding range of the third clamping member 53.
The wire spreader 1 further includes a first bracket 7, a plurality of first movable seats 14, a plurality of second movable seats 15, a plurality of third movable seats 16, and a plurality of fourth movable seats 17, and the first movable seats 14, the second movable seats 15, the third movable seats 16, and the fourth movable seats 17 are movable along the second direction B relative to the first bracket 7. Referring to fig. 18b and 19a, a first chuck 71 is provided on the first support 7 to fix the weft yarn 23 on the first support 7, so that the weft yarn 23 passing through the perforation 24 can be fixed relative to the first warp yarn 21 and the second warp yarn 22, thereby facilitating subsequent knitting. After the first grip 71 grips the weft yarn 23, the third grip 53 can be moved in the first direction a such that the third grip 53 is separated from the weft yarn 23. Since the third gripper 53 moves in the first direction a with respect to the weft yarn 23 at this time, the weft yarn 23 moves in the opposite direction to the first direction a with respect to the third gripper 53, and the plurality of grippers 532 do not restrict the relative movement of the weft yarn 23 and the third gripper 53, so that the third gripper 53 can be smoothly separated from the weft yarn 23.
Alternatively, the weft yarn 23 is disposed in the gripping body 531 and the gripping body extends in the first direction a to limit extension of the weft yarn 23 in the first direction a. By providing a gripping body to limit the extension of the weft thread 23 only in the first direction a, the weft thread 23 is not skewed, allowing it to pass better through the perforations 24.
By the above scheme, the movable seat can be driven to drive the weft yarn 23 to move so as to arrange the weft yarn 23 neatly. Taking the example shown in fig. 20a and 16e as an example, the second movable seat 15 is provided with the third abutting piece 1123 and the fourth abutting piece 1124, at this time, the third abutting piece 1123 is at the third abutting position (low position), and the fourth abutting piece 1124 is at the fourth abutting position (high position), so when the second movable seat 15 moves along the second direction B, the third abutting piece 1123 can contact the weft yarn 23 located in front of the second direction B, and drive the weft yarn 23 to move so that the weft yarn 23 and other weft yarns 23 are aligned in order, as shown in fig. 20B. Meanwhile, the third driving device 1121 may drive the third abutting piece 1123 to move upward so that the third abutting piece 1123 cannot contact the weft yarn 23.
In some embodiments, the user first alternates the first warp yarn 21 with the second warp yarn 22 along the first direction a. And continuously applying force to the first warp yarn 21 and the second warp yarn 22 to ensure that the first warp yarn 21 and the second warp yarn 22 are tensioned and extend along the second direction B, and simultaneously, adopting the yarn stretching device 1 to form wavy yarns on the first warp yarn 21 and the second warp yarn 22 respectively, as shown in fig. 12a and 14d, and forming perforations 24 between the first warp yarn 21 and the second warp yarn 22 to allow the weft yarn 23 to pass through along the first direction a. At this time, the first abutment 1113 is in the first abutment position, the second abutment 1114 is in the second abutment position, the third abutment 1123 is in the third abutment position, the fourth abutment 1124 is in the fourth abutment position, the fifth abutment 1233 is in the fifth abutment position, the sixth abutment 1234 is in the sixth abutment position, the seventh abutment 1243 is in the seventh abutment position, and the eighth abutment 1244 is in the eighth abutment position.
Next, the weft yarn 23 is driven through the perforations 24 between the first warp yarn 21 and the second warp yarn 22 by moving the third clamping member 53. And the weft yarn 23 is fixed to the first bracket 7 by the first clip 71. The user may then return to the first remote position by letting the first abutment 1113 return to the first remote position or the second abutment 1114 return to the second remote position. And returning the third abutment 1123 to the third distant position or the fourth abutment 1124 to the fourth distant position, such that the first warp yarn 21 is tensioned and no longer undulates, as shown in fig. 13a, 15e and 16 e. Similarly, the user may also pull the second warp yarn 22 to be strained to form a wave shape by returning the fifth abutment 1233 to the fifth distant position or the sixth abutment 1234 to the sixth distant position, and returning the seventh abutment 1243 to the seventh distant position or the eighth abutment 1244 to the eighth distant position, as shown in fig. 13c, 15f and 16 f.
At this time, since the first abutting piece 1113 is at the first abutting position or the second abutting piece 1114 is at the second abutting position, when the first movable seat 14 is moved along the second direction B, the abutting piece at the abutting position can drive the weft yarn 23 located in front of the first movable seat to move, so that the weft yarn 23 is aligned.
The advantage of the above solution is that by having the first abutment structure 111 assume the condition shown in fig. 15e, on the one hand, the first groove 1115 confining the first warp yarn 21 can be detached, so that the first warp yarn 21 slides down, forming the shape shown in fig. 13a, without forming a wave, for the subsequent knitting. On the other hand, when it is necessary to move the weft, when the first abutting structure 111 is in the state shown in fig. 15e, since the second abutting piece 1114 can contact the weft 23 located in front of the second direction B thereof when the first abutting structure 111 is moved in the second direction B, the user can move the weft 23 by moving the first abutting structure 111 so that the weft 23 is aligned in order. It should be understood that the second abutment structure 112, the third abutment structure 123 and the fourth abutment structure 124 can all perform the above functions except for the first abutment structure 111, which is not described in further detail in this disclosure.
