Abstract
Description
Technical Field
[0001] This utility model relates to the field of quality inspection technology, and in particular to a tensile quality inspection device for yarn production. Background Technology
[0002] Yarn is a type of textile product made from various textile fibers through processing. It possesses a certain fineness, strength, and elasticity and is widely used in weaving, rope making, thread making, knitting, embroidery, and other crafts. Based on the different fiber forms, yarn can be mainly divided into two categories: staple fiber yarn and continuous filament yarn. Staple fiber yarn is made by combining shorter fibers through twisting and other methods, while continuous filament yarn is composed of continuous fibers and has higher uniformity and smoothness. In the yarn production process, tensile quality is one of the important indicators for measuring the mechanical and performance properties of yarn, and it directly affects key characteristics such as yarn strength, elasticity, and abrasion resistance.
[0003] However, in the traditional yarn tensile quality testing process, the yarn is prone to slippage at the clamping point. This slippage not only leads to inaccurate measurement data, but may also cause the test results to deviate from the actual mechanical properties of the yarn, thereby affecting the correct judgment of key indicators such as yarn strength and elongation. This may lead to misadjustment of production process parameters, and even affect the quality control and stability of the final product, thus having an adverse impact on production and quality management.
[0004] Therefore, it is necessary to design a tensile quality testing device for yarn production to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the drawback of yarn slippage during testing, which affects the testing results, the technical problem is to provide a tensile quality testing device for yarn production.
[0006] The technical solution is as follows: A tensile quality testing device for yarn production includes a controller, a first slide rail, a first clamping block, a first electric slider, a second clamping block, a core frame, a crossbar, a clamping plate, and an elastic element. The first slide rail is installed on the lower left side of the controller. The first clamping block is fixedly connected to the upper right side of the first slide rail. The first electric slider is slidably connected to the right side of the first slide rail. The second clamping block is fixedly connected to the right side of the first electric slider, and the second clamping block is located below the first clamping block. The core frame is fixedly connected to the upper part of the first slide rail. The crossbar is fixedly connected to the upper part of the core frame. The clamping plate is rotatably connected to the bottom of the crossbar. An elastic element is wound between the crossbar and the clamping plate. The first clamping block, the first electric slider, and the second clamping block are all electrically connected to the controller.
[0007] Furthermore, it also includes rubber blocks, with rubber blocks fixedly connected to the clamping surfaces of both the first and second clamping blocks.
[0008] Furthermore, it also includes a handle; a handle is fixedly connected to the right side of the plate.
[0009] Furthermore, it also includes a guide needle, with a scale groove on the front side of the first slide rail and a guide needle fixedly connected to the front of the second clamping block.
[0010] Furthermore, the starting position of the scale groove is located at two-thirds of the length of the first slide rail.
[0011] Furthermore, it also includes a second slide rail, a second electric slider, and a detection rod. The second slide rail is installed on the upper left side of the controller, and the second electric slider is slidably connected to the second slide rail. The second electric slider is electrically connected to the controller, and the detection rod is fixedly connected to the left side of the second electric slider.
[0012] The beneficial effects are as follows: 1. By opening the card plate with the handle, placing the yarn in the card core frame, and then releasing the handle, the elastic element will drive the card plate to automatically reset, thereby fixing the yarn and effectively preventing the yarn from slipping off during the testing process, ensuring the stability and reliability of the testing process.
[0013] 2. This utility model increases the friction between the yarn and the first and second clamping blocks by using rubber blocks on the first and second clamping blocks, effectively preventing the yarn from slipping during the testing process, thereby ensuring the accuracy of the test results. When the second clamping block moves the yarn downwards, the operator can observe the change in the length of the stretched yarn more intuitively and accurately through the cooperation of the guide needle and the scale groove, improving the reliability of the measurement and the convenience of operation.
[0014] 3. This utility model activates the second electric slider through a controller, causing the second electric slider to move the detection rod along the second slide rail to further test the yarn under tension. This allows for a more comprehensive and accurate evaluation of the yarn's quality and overall performance indicators, improving the accuracy and efficiency of the test. Attached Figure Description

Detailed Implementation
[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a controller 1, a first slide rail 2, a first clamping block 3, a first electric slider 4, a second clamping block 5, a core frame 6, a crossbar 7, a clamping plate 8, and an elastic element 9. The first slide rail 2 is installed on the lower left side of the controller 1 by screws. The first clamping block 3 is welded to the upper right side of the first slide rail 2. The first electric slider 4 is slidably connected to the right side of the first slide rail 2. The second clamping block 5 is welded to the right side of the first electric slider 4 and is located below the first clamping block 3. The core frame 6 is welded to the top of the first slide rail 2. The crossbar 7 is welded to the top of the core frame 6. The clamping plate 8 is rotatably connected to the bottom right side of the crossbar 7. An elastic element 9 is wound between the crossbar 7 and the clamping plate 8. The first clamping block 3, the first electric slider 4, and the second clamping block 5 are all electrically connected to the controller 1. The device also includes a rubber block 10. The clamping surfaces of the first clamping block 3 and the second clamping block 5 are glued with rubber blocks 10.
[0022] When using this device to test the tensile quality of yarn, the operator first opens the clamping plate 8 using handle 801, at which point the elastic element 9 is stretched. Next, the plastic core in the middle of the yarn is inserted into the core holder 6. Then, handle 801 is released, and the elastic element 9, under the action of restoring force, causes the clamping plate 8 to automatically reset, thus firmly fixing the yarn to the core holder 6 and preventing the yarn from slipping during the test. After fixing, the operator pulls down one end of the yarn, allowing the yarn end to pass through the gap between the first clamping block 3 and the second clamping block 5. Then, the controller 1 controls the second clamping block 5 to tighten the yarn. Next, the controller 1 activates the first electric slider 4, which moves the second clamping block 5 and the yarn it holds downwards along the first slide rail 2. When the first electric slider 4 moves to one-third of the length of the first slide rail 2, the controller 1 issues another command to control the first clamping block 3 to clamp the yarn, thus securing the yarn to the core holder 6. The yarn segment between the first clamping block 3 and the second clamping block 5 is fixed as a sample for testing. The rubber block 10 effectively increases the coefficient of friction between the clamping block and the yarn, thereby preventing yarn slippage and ensuring the accuracy of the test. After clamping, the controller 1 continues to control the first electric slider 4 to drive the second clamping block 5 and the yarn it holds to move downward, thereby applying tensile force to the yarn for tensile quality testing. The tensile data is transmitted to the controller 1 in real time for recording. The process is simple to operate and effectively improves the efficiency and accuracy of yarn tensile performance testing. After the test is completed, the controller 1 controls the first clamping block 3 and the second clamping block 5 to open. The operator rotates the yarn on the core holder 6 to wind it up. After winding, the handle 801 is pulled to open the card plate 8, and the elastic element 9 is stretched, removing the yarn from the core holder 6. Then, the handle is released, and the elastic element 9 drives the card plate 8 to reset. Finally, the controller 1 controls the first electric slider 4 to drive the second clamping block 5 to reset.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a handle 801, and the handle 801 is welded to the right side of the card plate 8.
[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a guide needle 11, a scale groove 201 is provided on the front side of the first slide rail 2, and the guide needle 11 is welded to the left side of the front part of the second clamping block 5.
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the starting position of the scale groove 201 is located at two-thirds of the length of the first slide rail 2.
[0026] like Figure 1 , Figure 4 and Figure 5As shown, it also includes a second slide rail 12, a second electric slider 13 and a detection rod 14. The second slide rail 12 is installed on the upper left side of the controller 1 by screws. The second electric slider 13 is slidably connected to the second slide rail 12. The second electric slider 13 is electrically connected to the controller 1. The detection rod 14 is welded to the left side of the second electric slider 13.
[0027] During yarn stretching tests, the second clamping block 5 moves the guide pin 11 up and down together. The staff can directly observe the relative position between the guide pin 11 and the scale groove 201 to more intuitively and accurately grasp the length change of the yarn during the stretching process. After completing the preliminary stretching performance evaluation, the controller 1 starts the second electric slider 13. The second electric slider 13 drives the detection rod 14 to move back and forth along the second slide rail 12 to further conduct detailed toughness and mechanical property tests on the stretched yarn, thereby more comprehensively and accurately evaluating the quality of the yarn and its comprehensive performance indicators.
