Description

Technical Field

[0001] This utility model relates to the field of monofilament abrasion resistance testing technology, specifically a monofilament abrasion resistance testing machine. Background Technology

[0002] Polypropylene monofilaments, due to their high strength, lightweight, and corrosion resistance, are widely used in ropes, high-strength ropes, and other fields. Their abrasion resistance directly affects the product's service life and safety. Therefore, abrasion resistance testing is not only a necessary step for processed ropes, but also crucial for testing the abrasion resistance of the monofilaments themselves. Existing monofilament abrasion resistance testing equipment struggles to simultaneously adapt to the testing needs of monofilaments with different diameters or specifications. Furthermore, existing testing equipment often uses a fixed friction test mode for the monofilament, lacking flexible test mode switching, thus failing to simulate the friction conditions in actual use scenarios. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a monofilament abrasion resistance testing machine. This solves the problem that existing monofilament abrasion resistance testing equipment is difficult to adapt to the testing needs of monofilaments of different diameters or specifications at the same time. In addition, existing testing equipment mostly sets the friction test mode of monofilament in a fixed state, lacking flexible test mode switching, which makes it impossible to simulate the friction state in actual use scenarios.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A monofilament abrasion resistance testing machine, comprising: Test bench; A friction assembly is mounted on a test bench. The friction assembly includes a rotatable friction wheel and a lifting structure that drives the friction wheel to rise and fall. The friction wheel is mounted on the lifting end of the lifting structure. A linear module is mounted on a test bench, and the moving end of the linear module is displaced along the radial direction of the friction wheel. A rotating platform is disposed on the moving end of a linear module, wherein the rotating platform includes a rotatable turntable; Multiple pulleys are arranged in a circular array on the turntable.

[0005] The beneficial effects of this utility model are: 1) By setting multiple hanging wheels arranged in a circular array on a rotatable turntable, polypropylene monofilaments of different diameters or specifications can be hung simultaneously. Combined with the linear module's radial displacement function along the friction wheel, the turntable is precisely moved under the friction wheel to achieve stable contact between the monofilament and the rotating friction wheel, thereby efficiently completing the wear resistance test. After the test is completed, the friction wheel is raised by the lifting structure, and the turntable rotates to quickly switch to the next monofilament for testing, improving the testing efficiency and comprehensiveness.

[0006] 2) In addition, the linear module supports a test mode in which the monofilament moves on the friction wheel. Compared with the traditional friction method of fixing the monofilament and rubbing it, it can more realistically simulate the stress state of the monofilament in actual use, thereby improving the accuracy and reliability of the test results.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the friction assembly also includes a first servo motor, an output shaft, a support plate, and a bushing. The first servo motor is fixed on the support plate, the bushing is located on one side of the first servo motor and fixed on the support plate, one end of the output shaft is coaxially fixed on the drive end of the first servo motor, and the other end of the output shaft passes through the bushing and is coaxially fixed on one side of the friction wheel.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by using the drive end of the first servo motor to drive the output shaft to rotate, the output shaft drives the friction wheel to rotate at high speed, thereby completing the friction of the single filament.

[0010] Furthermore, the lifting structure includes a sliding plate, a slide rail, a vertical plate, a screw, a nut, a handwheel, and a fixing frame. The vertical plate is fixed on the test bench, the slide rail is fixed on one side of the vertical plate, the sliding plate slides outside the slide rail, and the sliding plate is fixed to the bottom of the bearing plate.

[0011] Furthermore, one end of the screw is rotatably connected to the bottom of the bearing plate via a rotating shaft, and the other end of the screw is rotatably connected to the test bench via a rotating shaft.

[0012] Furthermore, the nut is screwed onto the outside of the screw rod by a thread, the fixing bracket is fixed between the nut and the slide plate, and the handwheel is fixed to the outside of the screw rod.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by holding the handwheel, the screw is rotated. Due to the interaction between the threads, the bearing plate can drive the slide plate to slide up and down on the slide rail, thereby adjusting the horizontal height of the friction wheel. This not only facilitates the switching of single wires, but also adjusts the force intensity of the friction wheel on the single wire.

[0014] Furthermore, the rotating platform also includes a second servo motor, which is fixed on the moving end of the linear module, and the turntable is coaxially fixed on the driving end of the second servo motor. Attached Figure Description

[0017] 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.

[0018] Polypropylene monofilaments, due to their high strength, lightweight, and corrosion resistance, are widely used in ropes, high-strength ropes, and other fields. Their abrasion resistance directly affects the product's service life and safety. Therefore, abrasion resistance testing is not only a necessary step for processed ropes, but also crucial for testing the abrasion resistance of the monofilaments themselves. Existing monofilament abrasion resistance testing equipment struggles to simultaneously adapt to the testing needs of monofilaments with different diameters or specifications. Furthermore, existing testing equipment often uses a fixed friction testing method for the monofilament, lacking flexible test mode switching, making it impossible to simulate the friction conditions in actual use scenarios. To address these issues, the inventor has proposed a monofilament abrasion resistance testing machine.

[0019] The present invention provides the following preferred embodiments. like Figure 1 and Figure 2 As shown, a monofilament abrasion resistance testing machine includes: Test bench 100; Friction assembly 200 is mounted on test bench 100. Friction assembly 200 includes a rotatable friction wheel 210 and a lifting structure 220 that drives the friction wheel 210 to rise and fall. The friction wheel 210 is mounted on the lifting end of the lifting structure 220. Linear module 300 is set on test bench 100, and the moving end of linear module 300 is displaced along the radial direction of friction wheel 210. A rotating platform 400 is disposed on the moving end of the linear module 300, wherein the rotating platform 400 includes a rotatable turntable 402. Multiple pulleys 500 are arranged in a circular array on turntable 402; By setting multiple hanging wheels 500 arranged in a ring array on the rotatable turntable 402, polypropylene monofilaments of different diameters or specifications can be hung simultaneously. Combined with the radial displacement function of the linear module 300 along the friction wheel 210, the turntable 402 is precisely moved below the friction wheel 210, achieving stable contact between the monofilament and the rotating friction wheel 210, thereby efficiently completing the wear resistance test. After the test is completed, the friction wheel 210 is raised by the lifting structure 220, and the turntable 402 rotates to quickly switch to the next monofilament for testing, improving the testing efficiency and comprehensiveness. In addition, the linear module 300 supports a test mode in which the monofilament moves on the friction wheel 210. Compared with the traditional friction method of fixing the monofilament for friction, it can more realistically simulate the stress state of the monofilament in actual use, thereby improving the accuracy and reliability of the test results.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, the friction assembly 200 also includes a first servo motor 240, an output shaft 260, a support plate 250, and a bushing 230. The first servo motor 240 is fixed on the support plate 250. The bushing 230 is located on one side of the first servo motor 240 and fixed on the support plate 250. One end of the output shaft 260 is coaxially fixed on the drive end of the first servo motor 240, and the other end of the output shaft 260 passes through the bushing 230 and is coaxially fixed on one side of the friction wheel 210. The output shaft 260 is driven to rotate by the drive end of the first servo motor 240, and the output shaft 260 drives the friction wheel 210 to rotate at high speed, thereby completing the friction of the monofilament.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the lifting structure 220 includes a sliding plate 221, a slide rail 222, a vertical plate 223, a screw 224, a nut 225, a handwheel 226, and a fixing frame 227. The vertical plate 223 is fixed on the test bench 100, the slide rail 222 is fixed on one side of the vertical plate 223, the sliding plate 221 slides on the outside of the slide rail 222, and the sliding plate 221 is fixed to the bottom of the bearing plate 250. One end of the screw 224 is rotatably connected to the bottom of the bearing plate 250 through a rotating shaft, and the other end of the screw 224 is rotatably connected to the test bench 100 through a rotating shaft. The nut 225 is screwed onto the outside of the screw 224 through a thread. The fixing frame 227 is fixed between the nut 225 and the sliding plate 221, and the handwheel 226 is fixed to the outside of the screw 224. By holding the handwheel 226, the screw 224 is rotated. Due to the interaction between the threads, the bearing plate 250 can drive the slide plate 221 to slide up and down on the slide rail 222, thereby adjusting the horizontal height of the friction wheel 210. This not only facilitates the switching of single wires, but also adjusts the force intensity of the friction wheel 210 on the single wire.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the rotating platform 400 also includes a second servo motor 401, which is fixed on the moving end of the linear module 300, and the turntable 402 is coaxially fixed on the driving end of the second servo motor 401.

[0023] The specific working process of this utility model is as follows: (1) Prepare polypropylene monofilaments of different diameters First, attach polypropylene monofilaments of different diameters to adjacent rollers 500.

[0024] (2) Conduct friction test Subsequently, the linear module 300 is displaced along the radial direction of the friction wheel 210, causing the turntable 402 to move below the friction wheel 210. Then, the output shaft 260 is driven to rotate by the drive end of the first servo motor 240. The output shaft 260 drives the friction wheel 210 to rotate at high speed, achieving stable contact between the monofilament and the rotating friction wheel 210, thereby completing the wear resistance test of the monofilament.

[0025] (3) Switch to the next polypropylene monofilament abrasion test By holding the handwheel 226, the screw 224 is driven to rotate in the reverse direction. Due to the interaction between the threads, the bearing plate 250 can drive the slide plate 221 to slide upward on the slide rail 222, thereby raising the horizontal position of the friction wheel 210. Then, the second servo motor 401 drives the turntable 402 to rotate, allowing the next monofilament to rotate to below the friction wheel 210. Subsequently, the screw 224 is driven to rotate in the forward direction again, raising the horizontal height of the rotating friction wheel 210 until it contacts the monofilament, thus completing the wear resistance test of the next monofilament.

[0026] (4) Switching friction mode By displacing the moving end of the linear module 300 along the radial direction of the friction wheel 210, the monofilament can move and rub against the outside of the friction wheel 210.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
