Description

Technical Field

[0001] This invention relates to the field of yarn tension testing devices, specifically to a yarn tension testing device and method based on polyester filament processing. Background Technology

[0002] Polyester filament yarn is a continuous fiber yarn made from high-purity polyester chips through melt spinning. It features high strength, good abrasion resistance, strong wrinkle resistance, and excellent colorfastness. Its smooth and uniform fiber structure gives fabrics a smooth feel and good drape, while also possessing chemical stability such as hydrophobicity, quick-drying properties, acid and alkali resistance, and UV resistance. It is widely used in clothing, home textiles, and industrial fabrics. Through modification, it can also achieve cotton-like, linen-like, or elastic properties, making it a representative synthetic fiber yarn that combines cost-effectiveness and functionality.

[0004] The aforementioned device does not include components for easy fixation. When tension testing is required, it is not easy to quickly and conveniently fix the object to be tested, which complicates the operation and reduces work efficiency. Therefore, a yarn tension testing device and testing method based on polyester filament processing is proposed to address the above problems. Summary of the Invention

[0005] To address the problem that existing devices lack simplified fixing components, making it difficult to quickly and easily fix the object to be tested when tension testing is required, thus complicating the operation and reducing work efficiency, this invention proposes a yarn tension testing device and method based on polyester filament processing.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the yarn tension detection device based on polyester filament processing of the present invention includes an outer body of the device; a movable frame is provided inside the outer body of the device, the bottom end of the outer body of the device is fixedly connected to the bottom end of the fixed platform, and a fixing mechanism is provided inside the outer body of the device.

[0007] The facilitating fixing mechanism includes an outer body for clamping components. This outer body is also located at the bottom of the movable frame and the top of the fixed platform, and is fixedly connected to both. A first moving rod is sleeved inside the front end of the outer body, and is slidably connected to the first moving rod. The front end of the first moving rod is fixedly connected to the rear end of a first fixed connecting plate, and the rear end of the first moving rod is fixedly connected to the front end of a first transmission connecting plate. Circular openings are also provided on the left and right sides of the first transmission connecting plate. These circular openings are sleeved on the outside of a first rotating rod, and are rotatably connected to the first rotating rod. The top end of the first rotating rod is connected to the... The bottom of the second transmission connecting plate is fixedly connected to one side, and the bottom of the second transmission connecting plate is fixedly connected to the top of the second transmission rod. A rotatable transmission gear is sleeved on the outside of the second transmission rod. A fixed rod is sleeved at the middle position of the transmission gear, and the transmission gear is rotatably connected to the fixed rod. The bottom end of the fixed rod is fixedly connected to the bottom end of the inner body of the clamping member. The outer body of the clamping member is also sleeved with a first clamping block and a second clamping block near the rear position, and the outer body of the clamping member is slidably connected to the first clamping block and the second clamping block. The front ends of the first clamping block and the second clamping block are also fixedly connected to a transmission rack, which meshes with the transmission gear. Near the top of the clamping block, a guide moving block is also fixedly connected. This guide moving block is sleeved on the outside of the fixed guide rod and slidably connected to it. The left and right sides of the fixed guide rod are respectively fixedly connected to the left and right sides of the inner side of the clamping component's outer body. A first fixed sleeve rod is also fixedly connected to the left and right sides of the front end of the clamping component's outer body. A third moving rod is sleeved inside the first fixed sleeve rod and slidably connected to it. The front end of the third moving rod is fixedly connected to the rear end of the first fixed connecting plate, and the rear end of the third moving rod is fixedly connected to the front end of the first limiting moving plate. The first limiting moving plate is slidably connected to a first fixed... The device has a fixed sleeve rod, with the rear end of the first limiting moving plate fixedly connected to the front end of the reset spring, the rear end of the reset spring fixedly connected to the inner rear end of the first fixed sleeve rod, the front end of the clamping part at the upper position of the device's outer main body fixedly connected to the second moving rod, and the front end of the clamping part at the lower position of the device's outer main body fixedly connected to the second fixed sleeve rod, the second moving rod inserted inside the second fixed sleeve rod, and the second moving rod slidably connected to the second fixed sleeve rod, the bottom end of the second moving rod fixedly connected to the top end of the second moving limiting plate, the second moving limiting plate slidably connected to the second fixed sleeve rod, and the front end of the second fixed sleeve rod fixedly connected to the rear end of the second fixed connecting plate.

[0008] Preferably, the first clamping block and the second clamping block are also fixedly connected to one end of a guide rod at their upper and lower ends, and the outer body of the clamping member is also fixedly connected to a fixed guide block at its upper and lower ends. The other end of the guide rod is inserted into the fixed guide block, and the guide rod is slidably connected to the fixed guide block.

[0009] Preferably, the right end of the first clamping block is fixedly connected to the left end of the fixed rack plate, and the left end of the second clamping block has multiple sets of clamping tooth grooves. The fixed rack plate is inserted into the clamping tooth grooves, and the fixed rack plate is slidably connected to the first fixed sleeve rod.

[0010] A preferred method for detecting yarn tension based on polyester filament processing includes the following steps:

[0011] S1: First, press the second fixed connecting plate inward, causing the second fixed sleeve rod and the second moving rod to move inward simultaneously. As the second fixed sleeve rod and the second moving rod move inward, they will squeeze the first fixed connecting plate at both ends of the inner body of the device to move towards the position of the clamping part. When the first fixed connecting plate moves, it will cause the first moving rod to move along the inner body of the clamping part. At the same time, the first moving rod will cause the first transmission connecting plate and the first rotating rod to move simultaneously. When the first rotating rod moves, it will cause the second transmission connecting plate to rotate.

[0012] S2: When the second transmission connecting plate rotates, it drives the second transmission rod to rotate simultaneously. When the second transmission rod rotates, it drives the transmission gear to rotate synchronously along the outer side of the second transmission rod. The transmission gear also rotates along the outer side of the fixed rod.

[0013] S3: When the transmission gear rotates, it will drive the transmission racks at the front ends of the first clamping block and the second clamping block to move outwards respectively, thereby causing the first clamping block and the second clamping block to open. When the first clamping block and the second clamping block move, the guide moving block moves along the outside of the fixed guide rod. Then, the yarn is placed between the first clamping block and the second clamping block, and the second fixed connecting plate is released. Under the return force of the return spring, the first clamping block and the second clamping block clamp the yarn. When the first fixed connecting plate moves inwards, it will drive the third moving rod and the first limiting moving plate to retract along the inside of the first fixed sleeve rod, thereby the first limiting moving plate will squeeze the return spring to retract.

[0014] S4: When the first clamping block and the second clamping block move, they simultaneously drive the guide rod to move along the inside of the fixed guide block. When the first clamping block and the second clamping block move inward at the same time to clamp the yarn, they will drive the fixed rack plate to clamp the yarn into the clamping tooth groove.

[0015] The advantages of this invention are:

[0016] 1. This invention achieves easy fixation through a structural design that facilitates the fixing mechanism. It solves the problem that existing devices do not have components that simplify fixing, making it difficult to quickly and easily fix the object to be tested when tension testing is required. This leads to complicated operation and reduced work efficiency during fixing, thus improving convenience.

[0017] 2. This invention, through its structural design that facilitates the fixing mechanism, achieves the function of preventing detachment. It solves the problem that if no component is provided to prevent detachment, the object being tested is prone to detachment when the tension is too great and the clamping is not stable enough during tension testing, thus improving stability.

[0018] 3. Through the structural design of the fixing mechanism, this invention achieves the function of automatic spring-back clamping, which solves the problem that if there is no component for automatic spring-back clamping and fixing, the clamping operation steps are increased and the work efficiency cannot be improved, thus improving work efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The facilitating fixing mechanism includes a clamping outer body 10, which is also set at the bottom of the movable frame 2 and the top of the fixed platform 3. The clamping outer body 10 is fixedly connected to the bottom of the movable frame 2 and the top of the fixed platform 3 respectively. A first moving rod 11 is sleeved inside the front end of the clamping outer body 10, and the clamping outer body 10 is slidably connected to the first moving rod 11. The front end of the first moving rod 11 is fixedly connected to the rear end of the first fixed connecting plate 12. The first moving rod 11 is a circular rod design. The rear end of the first moving rod 11 is fixedly connected to the front end of the first transmission connecting plate 13.

[0037] Furthermore, a fixing rod 18 is sleeved at the middle position of the transmission gear 17, and the transmission gear 17 is rotatably connected to the fixing rod 18. The bottom end of the fixing rod 18 is fixedly connected to the bottom end of the inner body 10 of the clamping member, and the inner wall of the transmission gear 17 is designed to be circular.

[0038] Furthermore, a first clamping block 20 and a second clamping block 21 are also sleeved inside the outer body 10 of the clamping member near the rear position, and the outer body 10 of the clamping member is slidably connected to the first clamping block 20 and the second clamping block 21. The front ends of the first clamping block 20 and the second clamping block 21 are also fixedly connected to the transmission rack 19, and the transmission rack 19 is meshed with the transmission gear 17.

[0039] Furthermore, the first clamping block 20 and the second clamping block 21 are also fixedly connected to the upper front end of the first clamping block 20. The guide moving block 22 is sleeved on the outside of the fixed guide rod 29, and the guide moving block 22 is slidably connected to the fixed guide rod 29. The left and right sides of the fixed guide rod 29 are fixedly connected to the left and right sides inside the outer body 10 of the clamping member, respectively. The fixed guide rod 29 is a circular rod design.

[0040] Furthermore, the left and right sides of the front end of the clamping body 10 are also fixedly connected to the first fixed sleeve rod 26. The first fixed sleeve rod 26 is fitted with a third moving rod 25, and the first fixed sleeve rod 26 is slidably connected to the third moving rod 25. The front end of the third moving rod 25 is fixedly connected to the rear end of the first fixed connecting plate 12, and the rear end of the third moving rod 25 is fixedly connected to the front end of the first limiting moving plate 27. The first limiting moving plate 27 is slidably connected to the first fixed sleeve rod 26, and the rear end of the first limiting moving plate 27 is fixedly connected to the front end of the return spring 28. The rear end of the return spring 28 is fixedly connected to the rear end of the first fixed sleeve rod 26. The inner wall of the first fixed sleeve rod 26 is circular.

[0041] Furthermore, the front end of the clamping member outer body 10 at the upper position of the outer body 1 of the device is fixedly connected to the second moving rod 30, and the front end of the clamping member outer body 10 at the lower position of the outer body 1 of the device is fixedly connected to the second fixed sleeve rod 31. The second moving rod 30 is inserted inside the second fixed sleeve rod 31, and the second moving rod 30 is slidably connected to the second fixed sleeve rod 31. The bottom end of the second moving rod 30 is fixedly connected to the top end of the second moving limiting plate 33. The second moving limiting plate 33 is slidably connected to the second fixed sleeve rod 31. The inner wall of the second fixed sleeve rod 31 is circular. The front end of the second fixed sleeve rod 31 is fixedly connected to the rear end of the second fixed connecting plate 32.

[0042] During operation, first grasp the second fixed connecting plate 32 and push it inward. When the second fixed connecting plate 32 is pushed inward, it will simultaneously drive the second fixed sleeve rod 31 and the second moving rod 30 to move inward. When the second fixed sleeve rod 31 and the second moving rod 30 move inward, they will simultaneously drive the first fixed connecting plates 12 at both ends of the outer body 1 to move inward. When the first fixed connecting plate 12 moves outward, it will drive the first moving rod 11 to move backward along the front and rear interior of the clamping body 10. When the first moving rod 11 moves backward, it will simultaneously push the first transmission connecting plate 13 to move backward. After the first transmission connecting plate 13 moves backward, it will drive the first rotating... Rod 14 will drive the first rotating rod 14 to rotate inward. When the first rotating rod 14 rotates inward, it will drive the second transmission connecting plate 15 to rotate synchronously. When the second transmission connecting plate 15 rotates, it will also drive the second transmission rod 16 to move. Since the transmission gear 17 is sleeved on the outside of the second transmission rod 16, the transmission gear 17 will be driven by the second transmission rod 16 to rotate simultaneously. When the transmission gear 17 rotates outward, it will also rotate along the outside of the fixed rod 18. The fixed rod 18 can limit the position of the transmission gear 17. When the transmission gear 17 rotates outward, it will drive the transmission rack 19 to move outward simultaneously. When the transmission rack 19 moves outward, it will also drive the clamping mechanism. The first clamping block 20 and the second clamping block 21 inside the outer body 10 simultaneously move outward and open. As the first clamping block 20 and the second clamping block 21 move, they will move along the outside of the fixed guide rod 29. Simultaneously, the movement of the first clamping block 20 and the second clamping block 21 also drives the guide rod 35 to move along the inside of the fixed guide block 37. The guide rod 35 and the fixed guide block 37 enhance the support force provided to the first clamping block 20 and the second clamping block 21 during tensile tension testing. After the first clamping block 20 and the second clamping block 21 open, the yarn is vertically placed between the first clamping block 20 and the second clamping block 21 at the upper and lower ends inside the outer body 1 of the device. Then, the second fixed connecting plate 32 is released. Furthermore, due to the pushing of the second fixed connecting plate 32... At time 2, the first fixed connecting plate 12 will simultaneously press the third moving rods 25 on both sides into the first fixed sleeve rod 26. When the third moving rods 25 move into the first fixed sleeve rod 26, the first limiting moving plate 27 will move along the first fixed sleeve rod 26. During the movement of the first limiting moving plate 27, the return spring 28 will be compressed and contracted, and then the second fixed connecting plate 32 will be released. Under the rebound force of the return spring 28, the third moving rod 25 and the first fixed connecting plate 12 will be pushed back to their original positions. When the first fixed connecting plate 12 returns to its original position, the first clamping block 20 and the second clamping block 21 will simultaneously move towards the middle until the yarn is clamped. Then the outer body 1 of the device will be activated.The movable frame 2 moves upward, causing the clamping outer body 10 located at the upper part of the outer body 1 to move upward. Simultaneously, the clamping outer body 10 causes the second movable rod 30 to move upward along the inside of the second fixed sleeve rod 31, and also causes the second movable limiting plate 33 to move upward along the inside of the second movable rod 30, thereby performing tension testing.

[0043] Example 2

[0044] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 11 As shown, in the first embodiment of the present invention, the first clamping block 20 and the second clamping block 21 are also fixedly connected to one end of the guide rod 35 at their upper and lower ends. The outer body 10 of the clamping member is also fixedly connected to the upper and lower ends of the fixed guide block 37. The other end of the guide rod 35 is inserted into the fixed guide block 37, and the guide rod 35 is slidably connected to the fixed guide block 37. The guide rod 35 is a circular rod design.

[0045] Furthermore, the right end of the first clamping block 20 is fixedly connected to the left end of the fixed rack plate 23, and the left end of the second clamping block 21 has multiple sets of clamping tooth grooves 36. The fixed rack plate 23 is inserted into the clamping tooth grooves 36, and the fixed rack plate 23 is slidably connected to the first fixed sleeve rod 26.

[0046] Furthermore, a method for detecting yarn tension based on polyester filament processing includes the following steps:

[0047] S1: First, press the second fixed connecting plate 32 inward, causing the second fixed sleeve rod 31 and the second moving rod 30 to move inward simultaneously. When the second fixed sleeve rod 31 and the second moving rod 30 move inward, they will squeeze the first fixed connecting plate 12 at both ends of the inner upper and lower parts of the outer body 1 of the device to move towards the position of the outer body 10 of the clamping member. When the first fixed connecting plate 12 moves, it will drive the first moving rod 11 to move along the inner part of the outer body 10 of the clamping member. At the same time, the first moving rod 11 drives the first transmission connecting plate 13 and the first rotating rod 14 to move simultaneously. When the first rotating rod 14 moves, it drives the second transmission connecting plate 15 to rotate.

[0048] S2: When the second transmission connecting plate 15 rotates, it drives the second transmission rod 16 to rotate simultaneously. When the second transmission rod 16 rotates, it drives the transmission gear 17 to rotate synchronously along the outer side of the second transmission rod 16. The transmission gear 17 also rotates along the outer side of the fixed rod 18.

[0049] S3: When the transmission gear 17 rotates, it will drive the transmission rack 19 at the front end of the first clamping block 20 and the second clamping block 21 to move outward respectively, thereby causing the first clamping block 20 and the second clamping block 21 to open. When the first clamping block 20 and the second clamping block 21 move, the guide moving block 22 will move along the outside of the fixed guide rod 29. Then the yarn will be placed between the first clamping block 20 and the second clamping block 21, and the second fixed connecting plate 32 will be released. Under the rebound force of the return spring 28, the first clamping block 20 and the second clamping block 21 will clamp the yarn. When the first fixed connecting plate 12 moves inward, it will drive the third moving rod 25 and the first limiting moving plate 27 to retract along the inside of the first fixed sleeve rod 26, thereby the first limiting moving plate 27 will squeeze the return spring 28 to retract.

[0050] S4: When the first clamping block 20 and the second clamping block 21 move, the guide rod 35 moves along the inside of the fixed guide block 37. When the first clamping block 20 and the second clamping block 21 move inward to clamp the yarn, the fixed rack plate 23 will clamp the yarn into the clamping tooth groove 36.

[0051] During operation, when the first clamping block 20 and the second clamping block 21 clamp the yarn backward, they will drive the fixed rack plate 23 to insert into the clamping tooth groove 36. When the fixed rack plate 23 is inserted into the clamping tooth groove 36, the fixed rack plate 23 simultaneously drives the yarn to insert into the clamping tooth groove 36, thereby enhancing the clamping effect and preventing detachment.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

S3: When the transmission gear rotates, it will drive the transmission racks at the front ends of the first clamping block and the second clamping block to move outwards respectively, thereby causing the first clamping block and the second clamping block to open. When the first clamping block and the second clamping block move, the guide moving block moves along the outside of the fixed guide rod. Then, the yarn is placed between the first clamping block and the second clamping block, and the second fixed connecting plate is released. Under the return force of the return spring, the first clamping block and the second clamping block clamp the yarn. When the first fixed connecting plate moves inwards, it will drive the third moving rod and the first limiting moving plate to retract along the inside of the first fixed sleeve rod, thereby the first limiting moving plate will squeeze the return spring to retract. S4: When the first clamping block and the second clamping block move, they simultaneously drive the guide rod to move along the inside of the fixed guide block. When the first clamping block and the second clamping block move inward at the same time to clamp the yarn, they will drive the fixed rack plate to clamp the yarn into the clamping tooth groove.
