Technical Field
[0001] This utility model relates to the field of single yarn strength machine technology, and in particular to a yarn splitting device on a single yarn strength machine. Background Technology
[0002] After spinning, the yarn is wound into a yarn cake for easy transportation, storage, and use. The yarn cake after spinning needs to be tested for the breaking strength of the yarn fibers and the breaking elongation to confirm whether the yarn meets the quality standards. This test is called strength-elongation test.
[0003] The tensile strength test data of yarn needs to be tested using a fully automatic single yarn tensile strength tester. Multiple yarns can be hung at the same time for each test. The number of yarns tested at one time varies depending on the model of the single yarn tensile strength tester, but it can generally test 20 yarns at the same time.
[0004] During testing, the threads of different yarn cakes are first hung on the yarn guide device of the tensile testing machine. Then, the yarn pulling device is used to press the hung yarn close to the rear end of the yarn cake. The yarn is then clamped and pulled by the tensile testing machine. Various sensors are then used to detect the tensile length and pulling force of the yarn to achieve the testing purpose.
[0005] Multiple yarn tests are performed sequentially, one by one. When a yarn on a yarn cake is being tested, the yarn on the yarn cake is stretched out and pulled forward. At this time, only one yarn is moving while the other yarns remain stationary. However, all the clamped yarns move to the right on the single yarn tensile testing machine together and approach the yarn pulling hook, so that the rightmost yarn is hooked with the yarn pulling hook. Then, the clamps of the tensile testing machine hold and pull the hooked yarn for testing.
[0006] The yarn is connected to the hook, and in reality, only one yarn needs to be moved horizontally. However, in modern single-yarn tensile testing machines, all yarns move synchronously or cannot move at all. This makes it easy for the moving yarn to become tangled with other yarns. What was supposed to be a single yarn may become multiple yarns due to tangling, leading to test errors. It's also possible that during testing, the hook might pull another yarn off its original track, preventing it from being gripped by the tensile testing machine's fixtures. This will also affect the normal testing process, requiring re-attaching the yarn and retesting, thus reducing work efficiency.
[0007] Based on this, this utility model designs a yarn splitting device on a single yarn strength machine to solve the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a yarn splitting device for a single yarn strength tester. The guide plate of this device guides and limits the yarn at the pulling end, ensuring that each yarn to be tested is stably hooked and will not slip. Multiple pressure plates are added, and each pressure plate can hook and guide one yarn. At the same time, only one yarn is moved each time it is pulled, effectively avoiding the situation where multiple yarns move simultaneously and become entangled. This device can guide the yarn more stably and press the same yarn firmly on the same pressure plate, ensuring that the yarn is pressed firmly and preventing slippage when the yarn is pulled, thus improving the detection accuracy.
[0009] This utility model is implemented as follows: a yarn splitting device on a single yarn strength machine, comprising:
[0010] Machine body, wire guide plate, wire pressing plate, wire guide hook, and wire pressing rod;
[0011] The wire guide plate is a long plate that is horizontally arranged in the left-right direction. The wire guide plate can be slidably installed on the top front side of the machine body.

[0012] Two wire-hanging rods are provided on the front side of the wire guide plate. The two wire-hanging rods are horizontally arranged in the left-right direction and are respectively arranged on the upper and lower sides of the wire guide plate without contacting each other. The wire-hanging rods move synchronously with the wire guide plate. Multiple wire-winding discs are provided on the front side of each wire-hanging rod. The multiple wire-winding discs on the same wire-hanging rod are evenly distributed on the same straight line in the left-right direction.
[0013] The machine body is a single yarn strength machine, and a drawing motor and a drawing clamp are installed on the front side of the machine body;
[0014] The wire drawing motor has a sheet-like wire drawing hook on its telescopic end. The wire drawing hook is positioned in front of the wire guide plate without contact, and a barb is provided on the left end of the wire drawing hook.
[0015] The wire-pulling hook is horizontally positioned between the upper and lower wire-hanging rods, and the barb protrudes forward in front of the wire on the winding spool.
[0016] The drawing clamp is located directly below the wire drawing hook;
[0017] A translation groove is provided on the rear top side of the machine body. The translation groove is horizontally arranged in the left-right direction, and the translation groove and the guide wire hanging plate are parallel to each other.
[0018] The wire pressing plate is a flat plate, and a wire guide hook is provided on each of the front and rear sides of the top of the wire pressing plate; the two wire guide hooks on the top of the same wire pressing plate are in the same vertical plane;
[0019] A drive motor is placed at the bottom of the wire pressing plate, and each drive motor is slidably mounted in a translation groove.
[0020] Each of the wire pressing plates is positioned above the translation groove by a drive motor, and each of the wire pressing plates is individually driven to translate within the translation groove by its own drive motor;
[0021] The pressure rod is a horizontally arranged long rod with telescopic rods at both ends. The lower end of the telescopic rod is vertically fixed to the left and right ends of the translation groove. The pressure rod is horizontally clamped above the translation groove by the telescopic rods. The pressure rod can be raised to clamp the top of each pressure plate.
[0022] Furthermore, both the wire guide and the wire hook are open-ended ceramic wire guide components;
[0023] The number of each wire guide is the same as the number of wire pressing plates.
[0024] Furthermore, a wire-pressing groove is formed by a downward recess at the top of the wire-pressing plate.
[0025] The wire pressing groove is an arc-shaped groove with an open top, and the inside of the wire pressing groove is covered with an anti-slip pad;
[0026] The pressure groove is located directly below the pressure rod, and when the pressure rod 5 is pressed down, it fits tightly against the pressure groove 32.
[0027] Furthermore, the front guide wire hook extends forward at an angle, and the rear guide wire hook extends backward at an angle outside the machine body; the included angle between the front and rear guide wire hooks in the same vertical plane is between 40° and 60°.

[0032] The wire hook does not contact the wire hanging rod.
[0033] The beneficial effects of this utility model are: 1. This utility model adds multiple wire pressing plates, and each wire pressing plate can move independently, so that each wire pressing plate can synchronously follow the speed of the wire drawing motor, thereby synchronizing the translational guidance of the wire with the translational speed of the wire pulling by the wire hanging rod, effectively ensuring that the wire is stably pulled to the wire breakage clamp of the drawing machine, and ensuring that each wire can be translated and pulled to the clamp for effective detection;
[0034] 2. This device is equipped with multiple pressure plates, each of which can move independently. Therefore, the undetected wires can remain stationary, while only the single wire to be detected is moved. This structure ensures that other wires are not moved during detection, and the wires are not pulled to move. This effectively avoids the situation where the wires move and travel simultaneously, thus making it less likely for the wires to tangle and improving detection accuracy. Attached Figure Description

Detailed Implementation
[0045] Please see Figures 1 to 7 As shown, this utility model provides a yarn splitting device on a single yarn strength machine. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.
[0046] In a specific embodiment of the technical solution of this utility model:
[0047] It includes the machine body 1, the wire guide plate 2, the wire pressing plate 3, the wire guide hook 4, and the wire pressing rod 5;
[0048] The wire guide plate 2 is a long plate that is horizontally arranged in the left and right direction. The wire guide plate 2 can be slidably installed on the top front side of the machine body 1. Multiple wire guides 21 are evenly spaced on the top of the wire guide plate 2. The multiple wire guides 21 are arranged in the same straight line in the left and right direction. The wire guides 21 and the wire guide hooks 4 are both open wire guide ceramic parts.
[0049] The number of each wire guide 21 is the same as that of the wire pressing plate 3, ensuring that a wire passes sequentially from the rear through the wire guide hook 4 on the rear side of the same wire pressing plate 3, then through the wire guide hook 4 on the front side, and is hooked and guided with the corresponding wire guide 21, and then gently wound around the front winding spool 131, and is simultaneously hooked with the two winding spools 131 corresponding to the upper and lower order. That is, if the same wire is hooked with the leftmost winding spool 131, it must also be hooked with the leftmost winding spool 131 of the lower wire hanging rod 13, and is also hooked and guided with the leftmost wire guide 21 and the two wire guide hooks 4 on the leftmost wire pressing plate 3, forming a one-to-one wire guiding state, ensuring that each wire is separated from the others.
[0050] Two wire-hanging rods 13 are provided on the front side of the wire guide plate 2. The two wire-hanging rods 13 are horizontally arranged in the left and right direction and are respectively arranged on the upper and lower sides of the wire guide plate 2 without contacting each other. The wire-hanging rods 13 move synchronously with the wire guide plate 2. Multiple wire-winding discs 131 are provided on the front side of each wire-hanging rod 13. The multiple wire-winding discs 131 on the same wire-hanging rod 13 are evenly distributed on the same straight line in the left and right direction.
[0051] The winding disc 131 is a disc, and the winding disc 131 is fixedly connected to the hanging rod 13 by a round rod. The number of winding discs 131 on the same hanging rod 13 is the same as the number of guides 21, and the number of winding discs 131 on the upper and lower hanging rods 13 is also the same.
[0052] The lower wire hanging rod 13 is located to the left of the upper wire hanging rod 13, which makes the position of the upper wire winding disc 131 also correspondingly located to the left of the upper wire winding disc 131.
[0053] The wire hook 12 does not contact the wire hanging rod 13.
[0054] The machine body 1 is a single yarn strength machine. The front side of the machine body 1 is equipped with a drawing motor 11 and a drawing clamp 14. The drawing clamp 14 is a tensile machine clamp.
[0055] A sheet-like wire-drawing hook 12 is provided on the telescopic end of the wire-drawing motor 11. The wire-drawing hook 12 is provided on the front side of the wire guide plate 2 without contact. A barb 121 is provided on the left end of the wire-drawing hook 12.
[0056] The wire hook 12 is horizontally set between the upper and lower wire hanging rods 13. The barb 121 protrudes forward in front of the wire on the winding spool 131, so that the barb 121 is connected with the wire hanging on the winding spool 131, thereby pulling the wire to the right hook.
[0057] The pull clamp 14 is located directly below the wire hook 12;
[0058] A translation groove 31 is provided on the rear top side of the machine body 1. The translation groove 31 is horizontally arranged in the left and right direction, and the translation groove 31 and the guide wire hanging plate 2 are parallel to each other.
[0059] The wire pressing plate 3 is a flat plate, and a wire guide hook 4 is provided on each of the front and rear sides of the top of the wire pressing plate 3; the two wire guide hooks 4 on the top of the same wire pressing plate 3 are in the same vertical plane.
[0060] The front guide hook 4 extends forward at an angle, and the rear guide hook 4 extends backward at an angle outside the body 1; the angle between the front and rear guide hooks 4 in the same vertical plane is between 40° and 60°.
[0061] Two fixing rods 42 are provided on the top of the wire pressing plate 3. An extension rod 41 is locked to the upper end of the fixing rod 42 by a thread. The wire guide hook 4 is locked to the extension rod 41 by a thread.
[0062] The extension rod 41 has multiple replacement parts of different lengths, which makes it easy to adjust the position of the guide hook 4 to adapt to the guide requirements of different wires and is convenient to use.
[0063] A drive motor 33 is placed at the bottom of the wire pressing plate 3. Each drive motor 33 is slidably mounted in the translation groove 31. Each drive motor 33 drives its own wire pressing plate 3, so that each wire pressing plate 3 can be controlled independently.
[0064] Each pressing plate 3 is positioned above the translation groove 31 by a drive motor 33. Each pressing plate 3 is driven to translate independently within the translation groove 31 by its own drive motor 33. The drive motor 33 can be a linear motor or different segments of the same drive device for integrated control.
[0065] The top of the pressure plate 3 is recessed downwards to form a pressure groove 32.
[0066] The wire pressing groove 32 is an arc-shaped groove with an opening at the top, and the inside of the wire pressing groove 32 is covered with an anti-slip pad;
[0067] The wire pressing groove 32 is located directly below the wire pressing rod 5. When the wire pressing rod 5 is pressed down, it fits tightly with the wire pressing groove 32, and the wire is clamped between the wire pressing groove 32 and the wire pressing rod 5.
[0068] The pressure rod 5 is a horizontally set long rod. Telescopic rods 51 are set at both ends of the pressure rod 5. The telescopic rods 51 can be telescopic cylinders. The lower end of the telescopic rods 51 is vertically fixed to the left and right ends of the translation groove 31. The pressure rod 5 is horizontally clamped above the translation groove 31 by the telescopic rods 51. The pressure rod 5 can be raised and clamped to the top of each pressure plate 3.
[0069] It should be noted that:
[0070] 1. The function of the wire guide plate 2 is to move all the wires one position towards the wire pull hook 12 after each inspection, so that the wire pull hook 12 can hook the wires for the next shift. Therefore, the wire guide plate 2, the wire hanger 13, and the wire guide 21 move to the right synchronously. Because this process is synchronous and only involves lateral movement, the wires will not become entangled. Therefore, all the wire guide hooks 4 need to move to the right one position synchronously. All the wire pressing plates 3 of this device can move synchronously with the wire guide plate 2 to avoid the wires from becoming entangled when moving to the right. 2. However, when inspecting a single wire, it is necessary to hook the wire with the barb 121 of the wire pull hook 12. Figure 6 As shown, the yarn is pulled to the right by the barb 121. At this time, in the original single yarn strength machine, only the guide hook 4 is fixedly hooked at the rear end. The yarn will be pulled, or all the guide hooks 4 will move to the right. At this time, the yarn will not only be hooked by the barb 121 and pulled downward to elongate, but will also move along with it, which can easily cause the yarn to become tangled. This device can move only one pressure plate 3 when the guide hook 4 on one side of the yarn cake guides the yarn, and pull and move a single yarn while the other yarns remain stationary, thereby avoiding the pulled yarn from getting tangled with others and effectively avoiding the occurrence of abnormal detection.
[0071] When in use, the wire is pulled out from the wire cake at the rear of the machine body 1, so that the wire passes through the wire guide hook 4 at the rear, then through the wire guide hook 4 on the same pressure plate 3, and then through the wire guide 21 in the same order, and the upper and lower winding discs 131 on the front side in the corresponding order.
[0072] And each thread is pulled in this corresponding manner. As for the order of the guide hook 4, the guide device 21 and the winding disc 131, it is the order in the left and right direction. Each thread must be pulled and guided in turn from back to front. After the threads are pulled, it is necessary to ensure that the threads do not tangle with each other and that each thread is spread out.
[0073] Then the single yarn strength tester begins normal drawing operation. The drawing clamp 14 and the drawing hook 12 operate in the same way. Driven by the drawing motor 11, the drawing hook 12 moves to the left, pushing the yarn forward. The yarn is then hooked by the hook 121 and pulled to the right. The yarn is simply hung on the upper and lower winding discs 131, thus pulling the yarn to the right. The lower end of the yarn is pulled on the drawing clamp 14. Then the telescopic rod 51 is lowered, and the pressure rod 5 clamps the yarn in the pressure groove 32. The yarn is compressed, and then the drawing clamp 14 draws the clamped yarn. The single yarn strength tester detects and records the yarn performance parameters.
[0074] After a single wire completes the test, the wire guide plate 2 moves backward one wire station. At this time, all the wire guides 21 move to the right simultaneously, and all the wire pressing plates 3 move to the right along the translation groove 31. The wire pressing plates 3 are then released to prevent the wire from being pulled. This moves the wire to the pulling position of the wire pulling hook 12, making it easier to perform the next pull test.
[0075] Repeat the above steps to perform a pull-out test on all the threads in sequence.
[0076] The front side referred to in this device is the side where the drawing clamp 14 is located, and the left and right directions refer to the left and right sides of the wire travel direction. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
