Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn testing technology, and in particular to a device for testing the compact spinning effect of yarn. Background Technology
[0002] Textile and garment factories now place great emphasis on yarn appearance, especially yarn hairiness and pilling. To improve these issues, many yarn manufacturers employ compact spinning processes. The aggregation effect of compactly spun yarn directly impacts its hairiness and pilling grade. Currently, textile factories test yarn hairiness but cannot detect the aggregation effect of compact spinning. During subsequent weaving, yarns with poor aggregation during compact spinning are prone to fiber slippage, forming defects such as fuzz and fine details, and are also more likely to break, reducing weaving efficiency and lowering the yarn's anti-pilling grade.
[0003] Currently, textile factories measure the cohesion effect of compactly spun yarns manually by rubbing the yarn with their fingertips and observing the cohesion effect. However, due to differences in the force of each person's rubbing and the roughness of their fingertips, the test results vary, making it difficult to objectively and uniformly judge the yarn cohesion effect. Utility Model Content
[0004] To address the aforementioned technical deficiencies, this invention provides a yarn compact spinning effect testing device, which enables standardized testing of yarn compact spinning effect and reduces human error.
[0005] This utility model discloses a device for testing the compact spinning effect of yarn, including a first clamp and a second clamp. The middle parts of the first clamp and the second clamp are rotatably connected by a pin. The first clamp and the second clamp on one side of the pin are both raised outwards, while the first clamp and the second clamp on the other side of the pin are flat structures used to clamp the yarn. A torsion spring is provided between the first clamp and the second clamp on the raised side, and the torsion spring pushes the ends of the first clamp and the second clamp outwards. Arc-shaped inner grooves are provided on the opposite surfaces of the flat structures of the first clamp and the second clamp. The arc-shaped inner grooves on the first clamp and the arc-shaped inner grooves on the second clamp correspond one-to-one and form a through hole for clamping the yarn to test the compact spinning effect.
[0006] It also includes a base, with fixed clamping blocks at both ends of the base, and columns at both ends of the base. A crossbeam is provided on the top of the columns, and the crossbeam is located above the corresponding fixed clamping block. Vertical guide holes are provided at both ends of the crossbeam, and guide rods are provided in the corresponding guide holes. The lower ends of the guide rods are fixed to the movable clamping blocks. A cylinder is provided in the middle of the crossbeam, and the telescopic end of the cylinder is fixedly connected to the movable clamping block. Two sliding rods are provided at intervals between the fixed clamping blocks. Two sliding holes are provided on the first clamping body, and the sliding holes cooperate with the sliding rods. The first clamping body is slidably connected to the sliding rods. The clamping surface of the fixed clamping block is at the same horizontal height as the clamping surfaces of the first clamping body and the second clamping body.
[0007] Two connecting seats are provided on the outer surface of the upward-curving end of the second clamping body. The connecting seats are located at both ends in the width direction of the second clamping body. A rectangular recess is provided on the outer surface of the connecting seats. An elastic element is provided in the rectangular recess. The end of the elastic element is a rectangular connecting post, which is inserted into the rectangular recess. The end of the elastic element extends to the middle part in the length direction of the second clamping body. In its natural state, the elastic element exerts downward pressure on the second clamping body.
[0008] The present invention provides a yarn compact spinning effect testing device that uses a first clamp and a second clamp to hold the yarn.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0015] Example 1:
[0016] like Figures 1-5 As shown, this utility model discloses a yarn compact spinning effect testing device, including a first clamp 1 and a second clamp 2. The middle parts of the first clamp 1 and the second clamp 2 are rotatably connected by a pin 16. The first clamp 1 and the second clamp 2 on one side of the pin 16 are both raised outwards, while the first clamp 1 and the second clamp 2 on the other side of the pin 16 are flat structures used to clamp the yarn. A torsion spring 14 is provided between the first clamp 1 and the second clamp 2 on the outwardly raised side, and the torsion spring 14 pushes the ends of the first clamp 1 and the second clamp 2 outwards. Arc-shaped inner grooves 15 are provided on the opposite surfaces of the flat structure side of the first clamp 1 and the second clamp 2. The arc-shaped inner grooves 15 on the first clamp 1 correspond one-to-one with the arc-shaped inner grooves 15 on the second clamp 2 and form a through hole for clamping the yarn to test the compact spinning effect.
[0017] The first clamp 1 and the second clamp 2 are connected by a pin 16. The first clamp 1 and the second clamp 2 at the same end of the pin 16 are flat structures with an arc-shaped inner groove 15 on the flat structure to limit and clamp the yarn. The first clamp 1 and the second clamp 2 at the other end of the pin 16 are curved upwards, and a torsion spring 14 is set between them. The torsion spring 14 opens up the curved part of the first clamp 1 and the second clamp 2, so that the flat structure of the first clamp 1 and the second clamp 2 is kept in a clamped state.
[0018] In this case, the clamping force on the yarn can be kept constant each time the yarn is clamped and the clamping force is consistent when any operator performs the test. Therefore, the results of the yarn compact spinning effect test are more uniform and will not be affected by the operator's operation error.
[0019] In practical use, the yarn needs to be pulled back and forth after being clamped by the first clamp 1 and the second clamp 2. However, currently, the two ends of the yarn are not fixed, which causes friction between the side walls of the first clamp 1 and the second clamp 2 and the yarn, affecting the test results. In addition, the fact that the two ends of the yarn are not fixed interferes with the reciprocating movement of the first clamp 1 and the second clamp 2, affecting the test efficiency. Therefore, this solution has been optimized. For example, the testing device also includes a base 3, with fixed clamping blocks 4 at both ends of the base 3, and columns 5 at both ends of the base 3. A crossbeam 13 is set on the top of the column 5. The crossbeam 13 is located above the corresponding fixed clamping block 4. Vertical guide holes are set at both ends of the crossbeam 13, and guide rods 7 are set in the corresponding guide holes. The lower end of the guide rod 7 is fixed to the movable clamping block 6. A cylinder 8 is set in the middle of the crossbeam 13. The telescopic end of the cylinder 8 is fixedly connected to the movable clamping block 6. Two sliding rods 9 are spaced apart between the fixed clamping blocks 4. Two sliding holes 17 are correspondingly set on the first clamping body 1. The sliding holes 17 cooperate with the sliding rods 9. The first clamping body 1 is slidably connected to the sliding rods 9. The clamping surface of the fixed clamping block 4 is at the same horizontal height as the clamping surfaces of the first clamping body 1 and the second clamping body 2.
[0020] Fixed clamping blocks 4 are installed at both ends of the base 3, and movable clamping blocks 6 are installed above them. A cylinder 8 drives the blocks to move up and down, clamping the yarn. The first clamping body 1 is mounted on the sliding rod 9 between the fixed clamping blocks 4, and the two are slidably connected. This makes the reciprocating movement of the first clamping body 1 and the second clamping body 2 smoother and more stable. Simultaneously, the two ends of the yarn can be clamped between the fixed and movable clamping bodies, maintaining a stable and taut state. Furthermore, the clamping surface of the fixed clamping body is at the same height as the clamping surfaces of the first and second clamping bodies 1 and 2. In this way, the fixed and movable clamping bodies clamp the two ends of the yarn at the same height as the clamping bodies, so their sidewalls do not contact the yarn during the reciprocating motion of the first and second clamping bodies, thus not affecting the yarn's compact spinning effect test.
[0021] Two connecting seats 10 are provided on the outer surface of the upward-curving end of the second clamping body 2. The connecting seats 10 are located at both ends in the width direction of the second clamping body 2. A rectangular recess is provided on the outer surface of the connecting seat 10. An elastic element 12 is provided in the rectangular recess. The end of the elastic element 12 is a rectangular connecting post 11, which is inserted into the rectangular recess. The end of the elastic element 12 extends to the middle part in the length direction of the second clamping body 2. In its natural state, the elastic element 12 exerts downward pressure on the second clamping body 2.
[0022] Since the first clamping body 1 and the second clamping body 2 are pressurized by a torsion spring 14, the pressure is transmitted from one end to the other. During prolonged use, the second clamping body 2 may deform, so an elastic element 12 is used to support it and maintain stable clamping force. Two connecting seats 10 are provided on the second clamping body 2, each with a rectangular recess. A rectangular connecting post 11 is provided on the elastic element 12. After the rectangular connecting post 11 is inserted into the rectangular recess, it cannot rotate. In its natural state, the end of the elastic element 12 should be below the second clamping body 2. However, in reality, the end of the elastic element 12 abuts against the top of the second clamping body 2, so the elastic element is in a deformed state, exerting downward pressure on the second clamping body 2. The magnitude of the pressure exerted by the elastic element 12 on the second clamping body 2 is determined by the deformation and the elastic element itself. In actual use, the elastic element 12 can be a steel wire in a U-shape. Of course, the diameter of the steel wire is selected according to the actual situation.
[0023] The above scheme can maintain a stable clamping force between the second clamp 2 and the first clamp 1. When conducting compact spinning effect tests on different yarns, elastic elements 12 with different diameters and deformations after assembly can be selected according to the pressure requirements to ensure that the pressure applied by the elastic element 12 to the second clamp 2 reaches the required level.
