Description

Technical Field

[0001] This utility model relates to the field of monofilament tension testing technology, specifically a polyethylene monofilament tension testing device. Background Technology

[0002] Polyethylene monofilament, a material widely used in industry, fisheries, and construction, directly affects its performance and safety due to its tensile properties. Therefore, tensile testing of polyethylene monofilament is a crucial step in production and quality control. Current tensile testing devices for polyethylene monofilament typically employ a single fixed clamping structure or a simple tensioning device, which presents the following problems: First, the fixed position of the hanging rollers makes it difficult to adapt to the testing requirements of monofilaments of different lengths, thus limiting the testing range; second, most devices can only test a single monofilament, failing to handle multiple monofilaments of different lengths simultaneously, resulting in low testing efficiency. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a polyethylene monofilament tension testing device. Firstly, the fixed position of the hanging wheel in the testing device makes it difficult to adapt to the testing requirements of monofilaments of different lengths, resulting in a limited testing range. Secondly, most devices can only test a single monofilament and cannot simultaneously process multiple monofilaments of different lengths, leading to low testing efficiency.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A polyethylene monofilament tension testing device, comprising: support; A wall panel, which is fixed to a bracket; Two sets of suspension structures that displace in opposite directions and are used to hang monofilaments are provided. The two sets of suspension mechanisms are mirror-symmetrically arranged on one side of the wall panel. Each suspension mechanism includes a drive member that displaces along the edge of the wall panel, a first hanging wheel, a second hanging wheel, a third hanging wheel, a first linkage member, a second linkage member, a third linkage member, and a locking assembly. The first hanging wheel is located on the drive end of the drive member. The second and third hanging wheels are located on both sides of the first hanging wheel and are slidably arranged on the wall panel. The first linkage member is detachably connected to one side of the first hanging wheel. The second linkage member slides on the first linkage member and is detachably connected to one side of the second hanging wheel. The third linkage member slides on the first linkage member and is detachably connected to one side of the third hanging wheel. The locking assembly is arranged between the first and second linkage members and between the first and third linkage members to lock the positions of the second and third linkage members after displacement.

[0005] The beneficial effects of this utility model are: 1) By setting up two sets of mirror-symmetrical suspension structures, each set including a drive component, a first pulley, a second pulley, a third pulley, a linkage component, and a locking assembly, tension testing of polyethylene monofilaments in a taut state is achieved. The second and third pulleys can slide on the wall panel, and the distance between the second and third pulleys can be adjusted. In conjunction with the first linkage component driving the second and third linkage components, the two second and two third pulleys can each move in opposite directions and tighten the monofilaments, thus adapting to the testing requirements of monofilaments of different lengths, resulting in more comprehensive testing. In addition, the device can perform tension testing on multiple monofilaments of different lengths at the same time, greatly improving testing efficiency and effectively solving the problems of limited testing range and low efficiency.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the first linkage component includes a first support rod, a first sleeve, and a first connecting rod. One end of the first support rod is coaxially fixed to one side of the first gear wheel, the first sleeve is sleeved on the outside of the first support rod, and one end of the first connecting rod is fixed to the first sleeve.

[0008] Furthermore, the second linkage includes a second support rod, a second sleeve, and a second connecting rod. One end of the second support rod is coaxially fixed to one side of the second gear wheel. The second sleeve is sleeved on the outside of the second support rod. One end of the second connecting rod is fixed on the second sleeve, and the other end of the second connecting rod slides on the first connecting rod.

[0009] Furthermore, the third linkage includes a third support rod, a third sleeve, and a third connecting rod. One end of the third support rod is coaxially fixed to one side of the third pulley. The third sleeve is sleeved on the outside of the third support rod. One end of the third connecting rod is fixed to the third sleeve, and the other end of the third connecting rod slides on the first connecting rod.

[0010] Furthermore, the locking assembly includes two locking bolts, one end of which is screwed onto the second connecting rod and the second connecting rod respectively and abuts against the first connecting rod.

[0011] The beneficial effect of adopting the above-mentioned further solution is that it enables flexible adjustment of the distance between the second and third connecting wheels to adapt to the tension testing requirements of polyethylene monofilaments of different lengths. Specifically, after adjusting the distance between the second and third connecting wheels, the first sleeve is fitted onto the first support rod to form a stable first linkage. Subsequently, by utilizing the sliding effect of the second connecting rod on the first connecting rod, the second sleeve is fitted onto the second support rod to complete the connection of the second linkage. Similarly, by sliding the third connecting rod on the first connecting rod, the third sleeve is fitted onto the third support rod to form the third linkage. Finally, by tightening the two locking bolts, the sliding positions of the second and third connecting rods on the first connecting rod are fixed respectively, ensuring that when the first connecting wheel moves, it can synchronously drive the second and third connecting wheels to move.

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0015] Polyethylene monofilament, a material widely used in industry, fisheries, and construction, directly affects its performance and safety due to its tensile properties. Therefore, tensile testing of polyethylene monofilament is a crucial step in production and quality control. Existing technologies typically employ a single fixed clamping structure or a simple tensioning device for testing polyethylene monofilament, which presents the following problems: First, the fixed position of the hanging wheel makes it difficult to adapt to the testing requirements of monofilaments of different lengths, thus limiting the testing range; second, most devices can only test a single monofilament, failing to simultaneously process multiple monofilaments of different lengths, resulting in low testing efficiency. To address these issues, the inventor has proposed a polyethylene monofilament tensile testing device.

[0016] The present invention provides the following preferred embodiments. like Figures 1-4 As shown, a polyethylene monofilament tension testing device includes: Bracket 100; Wall panel 200, wall panel 200 is fixed on bracket 100; Two sets of suspension structures 300, displaced in opposite directions and used to hang monofilaments, are arranged mirror-symmetrically on one side of the wall panel 200. Each suspension mechanism includes a drive element 310 (including but not limited to electric push rods and linear modules) that displaces along the edge of the wall panel 200, a first hanging wheel 320, a second hanging wheel 330, a third hanging wheel 340, a first linkage 350, a second linkage 360, a third linkage 370, and a locking assembly 380. The first hanging wheel 320 is located on the drive end of the drive element 310, and the second hanging wheel 330 and the third hanging wheel 340 are respectively... Located on both sides of the first pulley 320 and slidably mounted on the wall panel 200, the first linkage 350 is detachably connected to one side of the first pulley 320, the second linkage 360 ​​slides on the first linkage 350 and is detachably connected to one side of the second pulley 330, and the third linkage 370 slides on the first linkage 350 and is detachably connected to one side of the third pulley 340. A locking assembly 380 is disposed between the first linkage 350 and the second linkage 360, and between the first linkage 350 and the third linkage 370, to lock the positions of the second linkage 360 ​​and the third linkage 370 after displacement. By setting up two sets of mirror-symmetrical suspension structures 300, each set including a drive component 310, a first hanging wheel 320, a second hanging wheel 330, a third hanging wheel 340, a linkage component, and a locking assembly 380, tension testing of polyethylene monofilaments in a taut state is achieved. The second hanging wheel 330 and the third hanging wheel 340 can slide on the wall panel 200, and the distance between the second hanging wheel 330 and the third hanging wheel 340 can be adjusted. In conjunction with the first linkage component 350 driving the second linkage component 360 and the third linkage component 370, the two second hanging wheels 330 and the two third hanging wheels 340 can each move in opposite directions and tighten the monofilaments, so as to meet the testing requirements of monofilaments of different lengths, resulting in more comprehensive testing. In addition, the device can perform tension testing on multiple monofilaments of different lengths at one time, greatly improving testing efficiency and effectively solving the problems of limited testing range and low efficiency.

[0017] In this embodiment, as Figures 1-4 As shown, the first linkage 350 includes a first support rod 351, a first sleeve 352, and a first connecting rod 353. One end of the first support rod 351 is coaxially fixed to one side of the first gear 320. The first sleeve 352 is sleeved on the outside of the first support rod 351. One end of the first connecting rod 353 is fixed to the first sleeve 352. The second linkage 360 ​​includes a second support rod 361, a second sleeve 362, and a second connecting rod 363. One end of the second support rod 361 is coaxially fixed to one side of the second gear 330. The second sleeve 362 is sleeved on the outside of the second support rod 361. One end of the second connecting rod 363 is fixed to the second sleeve 362. The other end of the second link 363 slides on the first link 353. The third linkage 370 includes a third support rod 371, a third sleeve 372, and a third link 373. One end of the third support rod 371 is coaxially fixed to one side of the third pulley 340. The third sleeve 372 is sleeved on the outside of the third support rod 371. One end of the third link 373 is fixed on the third sleeve 372, and the other end of the third link 373 slides on the first link 353. The locking assembly 380 includes two locking bolts. One end of each locking bolt is screwed onto the second link 363 and the first link 353 respectively and abuts against the first link 353. To achieve flexible adjustment of the distance between the second pulley 330 and the third pulley 340 to meet the tension testing requirements of polyethylene monofilaments of different lengths, specifically, after adjusting the distance between the second pulley 330 and the third pulley 340, the first sleeve 352 is fitted onto the first support rod 351 to form a stable first linkage 350. Subsequently, by utilizing the sliding effect of the second connecting rod 363 on the first connecting rod 353, the second sleeve 362 is fitted onto the second support rod 361 to complete the connection of the second linkage 360. Similarly, by sliding the third connecting rod 373 on the first connecting rod 353, the third sleeve 372 is fitted onto the third support rod 371 to form the third linkage 370. Finally, by tightening two locking bolts, the sliding positions of the second connecting rod 363 and the third connecting rod 373 on the first connecting rod 353 are fixed respectively, ensuring that when the first pulley 320 moves, it can synchronously drive the second pulley 330 and the third pulley 340 to move.

[0018] The specific working process of this utility model is as follows: After adjusting the distance between the second pulley 330 and the third pulley 340, the first sleeve 352 is fitted onto the first support rod 351. Then, by utilizing the sliding effect of the second connecting rod 363 on the first connecting rod 353, the second sleeve 362 is fitted onto the second support rod 361. Similarly, by utilizing the sliding effect of the third connecting rod 373 on the first connecting rod 353, the third sleeve 372 is fitted onto the third support rod 371. Finally, by tightening the two locking bolts, the sliding positions of the second connecting rod 363 and the third connecting rod 373 on the first connecting rod 353 are fixed respectively, ensuring that when the first pulley 320 moves, it can synchronously drive the second pulley 330 and the third pulley 340 to move, so as to complete the tension test of multiple sets of monofilaments of different lengths. In addition, since the first linkage 350, the second linkage 360 ​​and the third linkage 370 are all detachable, one or more monofilaments can be selected for testing.
