Description

The leverage that a kind of arm of force is adjustable

Technical field

The present invention relates to mechanical transmission fields, relate to the adjustable leverage of a kind of arm of force, particularly relate to a kind of adjustable leverage of the arm of force that is applicable to textile winding machine guide torque transfer.

Background technology

The kinematic mechanism of adjustable moving journey, the guide motion of in textile machine, using groove drum directly to contact with roller, the control of winding bobbin length is to be undertaken by changing groove drum, and therefore the stroke when the groove drum work of using unified size immobilizes, if want traverse then to need to change groove drum.Under non-stop-machine state, can't finish; the in the market adjusting for stroke all needs special fixed length mechanism; state-of-the-art bobbin-winding machine maker such as Savio orion and Schlafhorst series automatic winder all use the thread-carrier of unified traverse, are equipped with length control device and control coiling length.Invention and utility model patent for various length control devices are arranged in the present patent of China, but all be for length control device itself, such as patent 88100371.9, utilize a pressure roller of rotation fixed length dish and each weft yarn to cooperate, pressure roller is adjusted to two kinds of different weft yarns that many yarn looms weft yarns carrier provides measured length not working between dead position and the control position.Then mostly about the patent of guide is invention and utility models about various structure of thread-carrier, all be about multi-functional thread-carrier such as patent 94192477.7 and 96195793.X, but or clamping, or move the patent transition mechanism that groove drum and length control device is not united two into one along multi-axial cord.Groove drum need to have good heat conduction and electrostatic-proof function to guarantee winding quality in addition, reduce error, so cost of manufacture is higher.

Summary of the invention

Technical matters to be solved by this invention provides a kind of stable, reliable, convenient, efficient guide transmission actuation mechanism to adapt to the up-coiler technology of present multi_motor control; needn't change groove drum, utilize simple mechanism kinematic to realize the change of the stroke under the stopped status not.

The technical solution adopted for the present invention to solve the technical problems is: provide a kind of simple lever combination device to realize regulating the motion traverse of traversing of guide.Thereby utilize lever principle to apply power so that the driven driving thread-carrier motion of the other end at the lever fixed end.In order to make thread-carrier adapt to different winding bobbin length requirements, thereby changing lever arm of force length, the mode of use adjustable fulcrum changes lever driven end traverse.The concrete slide block that uses is as fixed end and movable end, and fixed end and lever are hinged; Making slideway for fulcrum and sliding end motion at lever; Fulcrum is comprised of slide block and support, and slide block connects lever, because in a single day fulcrum determines that slide block is static with respect to slideway, lever then can swing with respect to slideway by the sliding motion of slideway and contiguous block, according to technological requirement adjusting pole length.Lever combination is placed on the slideway, drive fixed end, lever is swung with respect to slideway, thereby and the hunting motion of lever will drive the motion requirement that the movable end slip realizes thread-carrier.

The adjustable leverage of a kind of arm of force of the present invention, mainly propped up by slide bar, slideway, lever and adjustable fulcrum and be configured to, slide bar and slideway connect to form fixed frame by pipe link, the hinged active sliding block of lever one end, active sliding block and slide bar are slidingly connected, the lever stage casing has sliding tray, be articulated in an end of adjustable fulcrum support with the fulcrum slide block of sliding tray bearing fit, the other end of adjustable fulcrum support is fixed on the fixed frame, the other end of lever has passive sliding tray, is stuck in the passive sliding tray with the traveller by movable slider of slideway bearing fit.

As preferred technical scheme:

The adjustable leverage of aforesaid a kind of arm of force, described slide bar and slideway are parallel to each other.

The adjustable leverage of aforesaid a kind of arm of force, described active sliding block and slide bar are slidingly connected and refer to that active sliding block has chute, and slide bar places chute.Slide bar places the chute of active sliding block.Active sliding block is along the slide bar translation gliding, and the end that activation lever and active sliding block are fixed is along the slide bar translation.The slip form is the single degree of freedom bearing fit, and slide block movement perpendicular direction picture is inside or outside.

The adjustable leverage of aforesaid a kind of arm of force describedly is comprised of shape all-in-one-piece traveller and slide block by movable slider, has chute on the slide block, and slideway places by the chute of movable slider.By the single degree of freedom sliding motion of active sliding block along slide bar, activation lever with it a fixing end along the slide bar translation, under the effect of adjustable fulcrum, lever by with driven the latter by the bearing fit of movable slider and make motion of translation along slideway.Slide block movement perpendicular direction picture is inside or outside.

The adjustable leverage of aforesaid a kind of arm of force, the described hinged fulcrum slide block that refers to does not have displacement of the lines with respect to the adjustable fulcrum support and only has angular transposition, and namely the fulcrum slide block only has to rotate with respect to the adjustable fulcrum support does not have translation.

The adjustable leverage of aforesaid a kind of arm of force, described passive sliding tray and sliding tray refer to carry out for slide block and lever at lever the structure of relative sliding.Also refer to simultaneously in active sliding block and be convenient to the slide block structure of relative sliding on slideway by movable slider.

The adjustable leverage of a kind of arm of force of the present invention, it is a kind of innovative form transition mechanism, in textile winding machine guide torque transfer can so that groove drum and guide length control device unite two into one, thereby the fulcrum that changes leverage changes arm of force length and changes stroke, and can replace sheave with more economical cam, save cost, the reel analysis of the characteristics of motion gets final product to cam when dropping into the weaving use, consistent with the principle of work of sheave, also be by outline line control traverse.Because leverage is simple in structure, makes letter and make things convenient for material in addition, usage space is in extensive range, so that this device almost can be worked in any place, is widely used.

Beneficial effect

The present invention compared with prior art has following advantage and good effect:

(1) requirement of change thread-carrier traverse, efficient stable have been realized by lever motion;

(2) arm of force is adjustable, so stroke is adjustable, can satisfy the job requirement of different coiling length;

(3) simple in structure, save space and material;

(4) simple to operate, GRR is good.
