棉纤维样本拆分机构及装置Cotton fiber sample splitting mechanism and device

技术领域technical field

本发明涉及一种棉纤维检测技术，尤其涉及的是一种棉纤维样本拆分机构及装置。The invention relates to a cotton fiber detection technology, in particular to a cotton fiber sample splitting mechanism and device.

背景技术Background technique

棉纤维是纺织工业的原料，其纤维品质的优劣直接影响纺织品的质量和产量。棉花纤维品质的分析项目包括纤维长度、纤维强度等。Cotton fiber is the raw material of the textile industry, and its fiber quality directly affects the quality and output of textiles. The analysis items of cotton fiber quality include fiber length, fiber strength and so on.

在对棉纤维品质进行检测时，则需要棉纤维样本，标准化检测流程中，原始送测样本的输入也是比较稳定的，是一团约120g-150g的棉团，这个棉团是原始采摘的棉花经简单弹棉处理后形成的，不可以有剪开或切断的断口。外形尺寸约为100×260×100（mm）；现阶段获得样本的方式是通过人工拆分，但是人工拆分效率较低，难以满足快速检测的需求。在开发自动化新方案过程中，也有采用拆棉针盘拆分的，但是该方式容易出现样本在拆分过程中纤维被撕扯断裂，从而导致检测数据的不准确的问题。When testing the quality of cotton fiber, cotton fiber samples are needed. In the standardized testing process, the input of the original test sample is also relatively stable. It is a cotton ball of about 120g-150g. This cotton ball is the original picked cotton. Formed after simple elastic cotton treatment, there must be no cut or cut fracture. The overall size is about 100×260×100 (mm); the way to obtain samples at this stage is through manual splitting, but the efficiency of manual splitting is low and it is difficult to meet the needs of rapid detection. In the process of developing a new automated solution, there is also a method of splitting cotton by needle discs, but this method is prone to the problem that the fibers of the sample are torn and broken during the splitting process, resulting in inaccurate detection data.

如公开号CN114646751A，一种棉纤维自动检测设备，包括颜色与杂质检测装置、抓取机构、拆分机构、长度和强度检测装置、第一样本盒与第二样本盒，所述第一样本盒与所述第二样本盒均用于放置棉纤维样本，所述第一样本盒底部开设有供棉纤维样本外露的颜色检测口和杂质检测口，所述第二样本盒底部开设有供棉纤维样本外露的长度检测口和强度检测口；所述拆棉组件包括拆棉气缸以及与所述拆棉气缸连接的拆棉针盘，所述拆棉气缸用于驱动所述拆棉针盘将位于所述长度检测口以及所述强度检测口处的棉纤维拆下来并使其落入所述送棉管中。For example, the publication number CN114646751A, an automatic detection equipment for cotton fibers, including a color and impurity detection device, a grasping mechanism, a split mechanism, a length and strength detection device, a first sample box and a second sample box, the first Both this box and the second sample box are used to place cotton fiber samples. The bottom of the first sample box is provided with a color detection port and an impurity detection port for cotton fiber samples to be exposed. The bottom of the second sample box is provided with a A length detection port and a strength detection port for exposing cotton fiber samples; the cotton removal assembly includes a cotton removal cylinder and a cotton removal needle plate connected to the cotton removal cylinder, and the cotton removal cylinder is used to drive the cotton removal needle The disc removes the cotton fibers located at the length detection port and the strength detection port and makes them fall into the cotton delivery pipe.

该专利中，通过下压气缸的大压力直接从大样本中部取出样本，需要的压力很大，压力太大又会导致棉纤维断裂，会导致拆分出的样本纤维被撕扯断裂，从而导致检测数据的不准确；且通过下压气缸配合针盘从样本中部拆分出样本，下压式获取样本的方式靠压力直接将一团棉纤维从中间硬压出去，很多时候压不出去，存在样本拆分不干净，导致样本质量不够，从而导致长强检测时容易出现大样本、小样本的情况，一旦频繁出现大样本、小样本，会导致单个样本重复检测，检测时间大幅度增加，影响检测的效率。同时，该专利中还通过强风吹送的方式送入检测口进行检测，而通过强风吹送进行运送难以确保样本送入检测口的位置。In this patent, the sample is directly taken out from the middle of the large sample through the high pressure of the downward pressure cylinder, which requires a lot of pressure. Too much pressure will cause the cotton fiber to break, which will cause the split sample fiber to be torn and broken, resulting in detection. The data is inaccurate; and the sample is split from the middle of the sample through the downward pressure cylinder and the needle disc. The downward pressure method of obtaining the sample relies on pressure to directly press out a group of cotton fibers from the middle. In many cases, it cannot be pressed out, and there are samples The splitting is not clean, resulting in insufficient sample quality, which leads to the situation of large samples and small samples prone to appear in Changqiang detection. Once large samples and small samples occur frequently, it will lead to repeated detection of a single sample, which will greatly increase the detection time and affect the detection. s efficiency. At the same time, in this patent, it is also sent into the detection port by strong wind blowing for detection, but it is difficult to ensure the position of the sample sent into the detection port by means of strong wind blowing.

具体实施方式Detailed ways

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

实施例一：Embodiment one:

如图1所示，棉纤维样本拆分机构，包括样本盒1、两个镜像布置的夹持组件2，两个所述夹持组件2能够同时水平方向相对或背向运动的位于所述样本盒1的两侧；从而实现两个夹持组件2同时从样本盒1内夹持棉纤维样本后向两侧撕扯，使其分离为拥有自然撕扯口的两份待检长度和强度检测样本。图1中为了显示夹持组件2有不同的工作状态，故左侧夹持组件2为夹持状态，右侧夹持组件2为未夹持状态。As shown in Figure 1, the cotton fiber sample splitting mechanism includes a sample box 1, twoclamping assemblies 2 arranged in mirror images, and the twoclamping assemblies 2 can move relative or back to each other in the horizontal direction at the same time. The two sides of the box 1; so as to realize that the twoclamping components 2 simultaneously clamp the cotton fiber sample from the sample box 1 and tear it to both sides, so that it is separated into two length and strength test samples with natural tear openings. In FIG. 1 , in order to show that the clampingassembly 2 has different working states, theleft clamping assembly 2 is in the clamping state, and theright clamping assembly 2 is in the unclamped state.

如图2所示，样本盒1是竖直截面为U型的壳体结构，其顶面和长度方向的两端为空，其底面包括多个沿长度方向开设的长条槽11，长条槽11为上下贯穿结构，但两端的长条槽11并未连通，两端的长条槽11也是对称布置，本实施例中，长条槽11总共十个，十个长条槽11均匀分布在样本盒1的两端，由其中一端可以看出，宽度方向上，两侧的长条槽11宽度大于位于中部的长条槽11；参考图6所示，这是由于两侧较宽的长条槽11需要容纳位于两侧最外侧的两排第一针具25，中部的长条槽11仅需容纳一排第一针具25。棉纤维样本与样本盒1在长度和宽度方向上相近即可，放置棉纤维样本时，保持样本均匀平铺在样本盒1内。As shown in Figure 2, the sample box 1 is a shell structure with a U-shaped vertical section, its top surface and two ends in the length direction are empty, and its bottom surface includes a plurality oflong grooves 11 opened along the length direction. Thegrooves 11 are up and down through the structure, but thelong grooves 11 at both ends are not connected, and thelong grooves 11 at both ends are also symmetrically arranged. In this embodiment, there are tenlong grooves 11, and the tenlong grooves 11 are evenly distributed in the The two ends of the sample box 1 can be seen from one of the ends. In the width direction, the width of theelongated grooves 11 on both sides is greater than that of theelongated grooves 11 in the middle; Theslot 11 needs to accommodate two rows offirst needles 25 located at the outermost sides on both sides, and thelong slot 11 in the middle only needs to accommodate one row of first needles 25 . The cotton fiber sample should be close to the sample box 1 in the length and width directions. When placing the cotton fiber sample, keep the sample evenly spread in the sample box 1 .

由于两侧的夹持组件2为相同结构，本实施例中以一个夹持组件2为例进行描述。如图3所示，所述夹持组件2包括基板21、夹板驱动件、第一夹板23、第二夹板24、第一针具25、第二针具26、第一针孔板27、第二针孔板28。其中，夹板驱动件为用于驱动第一夹板23以及第二夹板24上下运动的夹板气缸22，夹板驱动件也可以是其他能够实现上下方向往复运动的机构，如丝杆螺母机构、液压缸等。Since the clampingcomponents 2 on both sides have the same structure, oneclamping component 2 is taken as an example for description in this embodiment. As shown in FIG. 3 , the clampingassembly 2 includes abase plate 21, a splint driver, afirst splint 23, asecond splint 24, afirst pin 25, asecond pin 26, afirst pinhole plate 27, a Twopinhole plates 28. Wherein, the splint driver is asplint cylinder 22 for driving thefirst splint 23 and thesecond splint 24 to move up and down, and the splint driver can also be other mechanisms capable of reciprocating up and down, such as a screw nut mechanism, a hydraulic cylinder, etc. .

基板21为两个，两个基板21上下沿水平面对称设置，如图4所示，两个基板21的右侧均连接一个90度翻转机构，该90度翻转机构为开合气缸6，两个开合气缸6能够实现两个基板21张开与闭合。工作开始初期，开合气缸6动作，将位于上部的基板21顺时针旋转，位于下部的基板21逆时针旋转，实现夹持组件2像虎口一样张开，然后前进到夹持位的时候再将夹持组件2合起来，如图4中两个基板21呈平行状态。There are twosubstrates 21, and the twosubstrates 21 are arranged symmetrically along the horizontal plane up and down. As shown in Figure 4, the right sides of the twosubstrates 21 are connected with a 90-degree turning mechanism, which is the opening andclosing cylinder 6, and the two The opening andclosing cylinder 6 can realize the opening and closing of the twobase plates 21 . At the beginning of the work, the opening andclosing cylinder 6 acts to rotate theupper base plate 21 clockwise, and thelower base plate 21 rotates counterclockwise to realize the clampingassembly 2 opening like a tiger’s mouth, and then move it forward to the clamping position. When the clampingassembly 2 is put together, as shown in FIG. 4 , the twosubstrates 21 are in a parallel state.

如图4所述，同时参考图5，位于上面的基板21的顶端和位于下面的基板21的底端均呈U型折弯，折弯后的侧面用于安装夹板气缸22，两个夹板气缸22沿水平面镜像布置，夹板气缸22通过螺栓等方式连接在基板21上。位于上部的夹板气缸22的伸缩端与第一夹板23连接，第一夹板23的底面连接多个第一针具25，位于下部的夹板气缸22的伸缩端与第二夹板24连接，第二夹板24的顶面连接多个第二针具26。As shown in Figure 4, referring to Figure 5 at the same time, the top of theupper substrate 21 and the bottom of thelower substrate 21 are U-shaped bent, and the side after bending is used to install thesplint cylinder 22, twosplint cylinders 22 is arranged as a mirror image along the horizontal plane, and thesplint cylinder 22 is connected to thebase plate 21 by means of bolts or the like. The telescopic end of thesplint cylinder 22 on the upper part is connected with thefirst splint 23, and the bottom surface of thefirst splint 23 is connected with a plurality offirst needles 25, and the telescopic end of thesplint cylinder 22 at the lower part is connected with thesecond splint 24, and the second splint A plurality ofsecond pins 26 are connected to the top surface of 24 .

本实施例中，第一针具25、第二针具26均呈矩阵排列，本实施例中，第一针具25呈7*8的矩阵形式，第一针具25呈7*7的矩阵形式，当然，具体设置的排数和列数可以根据实际需要更换，以及相邻第一针具25、相邻第二针具26之间的距离可以根据实际需要设置，第一针具25与第二针具26排布无需过密。In this embodiment, thefirst needles 25 and the second needles 26 are arranged in a matrix. In this embodiment, thefirst needles 25 are in a matrix of 7*8, and thefirst needles 25 are in a matrix of 7*7. Form, of course, the number of rows and columns that are specifically set can be changed according to actual needs, and the distance between the adjacentfirst needles 25 and the adjacentsecond needles 26 can be set according to actual needs, thefirst needles 25 and The arrangement of the second needles 26 does not need to be too dense.

第一针具25与第二针具26均为圆柱形针状结构，端部可以是尖端，为使针更容易扎入样本，在保证强度的前提下针具的端部应尽量的尖。Both thefirst needle 25 and thesecond needle 26 are cylindrical needle-shaped structures, and the ends may be pointed. In order to make the needles penetrate into the sample more easily, the ends of the needles should be as sharp as possible under the premise of ensuring strength.

所述第一针具25在所述第二夹板24上的竖直方向投影与所述第二针具26不重合；即：参考图4或图7所示，第一针具25的竖直轴线与第二针具26的竖直轴线不重合，二者呈交错布置，为了避免第一针具25与第二针具26夹持时抵接在一起，降低对棉纤维的压实，压实交错后整体上摩擦力更大导致更难撕扯开，也更容易产生断裂的纤维，改变其内部结构，获得误差较大的检测结果。The vertical projection of thefirst needle 25 on thesecond splint 24 does not coincide with thesecond needle 26; that is: with reference to FIG. 4 or shown in FIG. 7, the vertical projection of thefirst needle 25 The axis does not coincide with the vertical axis of thesecond needle tool 26, and the two are arranged in a staggered manner. In order to avoid thefirst needle tool 25 and thesecond needle tool 26 from abutting together when they are clamped, the compaction to the cotton fiber is reduced. After actual interlacing, the overall friction force is greater, making it more difficult to tear apart, and it is also easier to produce broken fibers, change its internal structure, and obtain test results with large errors.

其中，如图7所示，所述第一针具25长度小于第二针具26的长度，这样做的目的是：在采用夹持组件2夹持棉纤维时，为了避免棉纤维因过于贴近样本盒1而造成挤压集中，进而产生影响撕扯的摩擦力，因此，第一针具25较短，使得第一针具25与第二针具26互相靠近、交错至夹持状态时棉纤维可以被第二针具26顶高一点，减少棉纤维与样本盒1的挤压。同时也可以避免棉纤维被压，导致其内部纤维交错从而改变了其内部结构。Wherein, as shown in Figure 7, the length of thefirst needle 25 is less than the length of thesecond needle 26. The purpose of doing this is: when the cotton fiber is clamped by the clampingassembly 2, in order to prevent the cotton fiber from being too close The sample box 1 causes extrusion concentration, and then produces the frictional force that affects tearing, therefore, thefirst needle 25 is shorter, makes the cotton fiber when thefirst needle 25 and thesecond needle 26 are close to each other and interlaced to the clamping state It can be pushed up a little by thesecond needle tool 26 to reduce the extrusion of the cotton fiber and the sample box 1 . At the same time, it can also avoid the cotton fiber being pressed, causing its internal fibers to intertwine and thus changing its internal structure.

如图3所示，同时参考图6所示，第一针孔板27与第二针孔板28水平连接基板21的中部，第一针孔板27与第二针孔板28上下间隔布置，第一针孔板27上包括多个与第一针具25位置对应的针孔，针孔的内径大于第一针具25的外径，即第一针具25在上下方向运动时，能够穿过第一针孔板27上的针孔；第二针孔板28上包括多个与第二针具26位置对应的针孔，针孔的内径大于第二针具26的外径，即第二针具26在上下方向运动时，能够穿过第二针孔板28上的针孔。As shown in FIG. 3 and referring to FIG. 6 at the same time, thefirst pinhole plate 27 and thesecond pinhole plate 28 are horizontally connected to the middle part of thesubstrate 21, and thefirst pinhole plate 27 and thesecond pinhole plate 28 are arranged at intervals up and down. Thefirst pinhole plate 27 includes a plurality of pinholes corresponding to the positions of the first needles 25. The inner diameter of the pinholes is larger than the outer diameter of the first needles 25, that is, when thefirst needles 25 move up and down, they can penetrate Through the pinholes on thefirst pinhole plate 27; thesecond pinhole plate 28 includes a plurality of pinholes corresponding to the positions of thesecond pinholes 26, and the inner diameter of the pinholes is greater than the outer diameter of thesecond pinholes 26, that is, the pinholes of thesecond pinholes 26. When thesecond needle tool 26 moves up and down, it can pass through the pinholes on thesecond pinhole plate 28 .

第一针具25与第二针具26在水平方向上与长条槽11的位置对应，即：包括第一针具25与第二针具26与长条槽11的位置对应，当然在本实施例中，第一针具25由于较短且由于第一针孔板27的限位，第一针具25一般不会插入到长条槽11内，仅第二针具26能够由样本盒1的底部穿过长条槽11。The first pins 25 and thesecond pins 26 correspond to the positions of theelongated slots 11 in the horizontal direction, that is, thefirst pins 25 and thesecond pins 26 correspond to the positions of theelongated slots 11. Of course, in this In the embodiment, due to the shortness of thefirst needle 25 and the limitation of thefirst pinhole plate 27, thefirst needle 25 is generally not inserted into theelongated groove 11, and only thesecond needle 26 can be inserted into the sample box. The bottom of 1 passes throughelongated groove 11.
