[0002] Polyethylene monofilament fishing line usually refers to fishing line made of polyethylene material, which has certain strength and wear resistance and is suitable for general fishing activities. Polyethylene is a common plastic material with good flexibility and corrosion resistance, so it is widely used in the manufacture of fishing line.

[0003] In this regard, the patent document with publication number CN206683979U discloses a fishing line wear resistance and curling test device, including a fishing line, a detection medium and a power mechanism; one end of the fishing line is fixed to the power mechanism, and the other end is fixed with a weight; the power mechanism is used to pull the fishing line to perform reciprocating friction motion on the detection medium; the power mechanism fixes one end of the fishing line, the weight fixes the other end of the fishing line, the middle end of the fishing line is placed on the detection medium, and then the power mechanism reciprocates to drive the fishing line to rub against the detection medium for detection, and the fishing line is removed after a period of reciprocating motion, and the anti-curling property of the fishing line is judged according to the curling degree of the fishing line, and the wear resistance of the fishing line can be judged by the wear degree of the fishing line, the detection is convenient and the detection reliability is high; the overall structure is simple and the cost is low.

[0004] In this regard, the patent document with publication number CN210571773U discloses a fishing line testing device, comprising a bracket, a motor is fixed on the front of the bracket, a wheel is fixed on the output end of the motor, an active rod is fixed on the wheel, a fixed rod is arranged on the inner side of the bracket, a fishing line is arranged on the fixed rod, one end of the fishing line is fixedly connected to the active rod, and a weight is fixed on the other end of the fishing line; the length of the active rod is the same as that of the fixed rod, and the outer surface of the active rod is provided with anti-slip grooves; the wheel is circular, and the active rod is located at the edge of the wheel; by providing the wheel, the active rod, the fixed rod, the motor and the groove, it is convenient to test the strength of multiple fishing lines, avoiding the traditional device that can only test one fishing line, resulting in slow testing efficiency and affecting the testing time, so as to improve the use effect and increase the practicality of the device.

[0005] Nowadays, when fishing lines are tested for strength, their strength is tested by pulling. However, due to the long length of the fishing line as a whole, the test requires a larger place.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 8The wear-resistant testing device for polyethylene monofilament fishing line of the present invention comprises a testing seat 11, a threaded rod 12 and a guide rod 13 are installed on the upper surface of the testing seat 11, the threaded rod 12 and the testing seat 11 are rotatably connected, the top ends of the threaded rod 12 and the guide rod 13 are connected to a top plate 14, a driving motor 15 is connected to the top surface of the top plate 14, the output end of the driving motor 15 is connected to the threaded rod 12, a side plate 17 is connected to the side of the testing seat 11, a lifting frame 18 is sleeved on the outer surface of the threaded rod 12, and a cover plate 16 is connected to the top surface of the lifting frame 18; When the wear resistance test of the polyethylene fishing line 27 is conducted, the test is conducted by better simulating the fishing line application environment. In order to test the entire fishing line, the polyethylene fishing line 27 is bent and then uniformly stretched. Then, the polyethylene fishing line 27 is restored after one stretching. By observing the state of the polyethylene fishing line 27, the strength of the polyethylene fishing line 27 can be further determined. The specific operation is as follows: The lifting frame 18 is provided with a pulling assembly 2, which includes an upper pulling rod 21, and a first limiting wheel 22 is movably connected to the outer surface of the upper pulling rod 21. A lower pull rod 24 is also provided on the test seat 11, and a second limiting wheel 25 is sleeved on the lower pull rod 24. A clamping piece 26 is provided on the side of the lifting frame 18. Two clamping pieces 26 are provided, one of which is connected to the lifting frame 18, and the other is connected to the test seat 11. Polyethylene is embedded in the interior of the first limiting wheel 22 and the second limiting wheel 25. The polyethylene fishing line 27, the clamping piece 26 is used to fix the two ends of the polyethylene fishing line 27, two groups of upper pulling rods 21 are provided, each group of upper pulling rods 21 is provided with a first limiting wheel 22, and two groups of lower pulling rods 24 are also provided, each group of lower pulling rods 24 is provided with a second limiting wheel 25, one end of the polyethylene fishing line 27 is first embedded in the first first limiting wheel 22, and then passes through the first second limiting wheel 25, and then passes through the second first limiting wheel 22, until it passes through the second second limiting wheel 25.

[0024] First, the two ends of the polyethylene fishing line 27 are clamped on the clamping pieces 26 respectively, and the polyethylene fishing line 27 is fixed by the clamping pieces 26. After being fixed, the polyethylene fishing line 27 is initially in a straight state. At this time, the driving motor 15 starts to work, and the driving motor 15 drives the lifting frame 18 to rise. When the lifting frame 18 rises, it is followed by the upper pulling rod 21 and the first limiting wheel 22, wherein the lower pulling rod 24 and the second limiting wheel 25 always remain stationary. When the distance between the upper pulling rod 21 and the lower pulling rod 24 continues to increase, the stretching of the polyethylene fishing line 27 is achieved, and it is convenient to better distribute the force in the stretching stage. At this time, the upper pulling rod 21 and the first limiting wheel 22 are kept in rotation connection, and the polyethylene fishing line 27 can be extended according to the change of tension. The rear drive causes the first limiting wheel 22 to rotate on the upper pulling rod 21, and each part of the polyethylene fishing line 27 can be stretched by rotation, so that when testing the tensile strength, the force is more uniform.

[0025] In addition, not only can the entire polyethylene fishing line 27 be evenly stressed, but in this way, the space required during the stretching process can be reduced, thereby greatly reducing the space required for testing.

[0026] In order to better simulate the working environment of the polyethylene fishing line 27, it is not only stretched in the vertical direction, but also stretched at different angles to better test the strength, which is specifically manifested in: The test seat 11 is also fixedly connected to a mounting plate 23, to which a simulation component 3 is connected, and the simulation component 3 includes a connecting plate 31, to which a rotating rod 32 is connected on a side of the connecting plate 31 away from the mounting plate 23, to which a mounting bracket 33 is connected at the end of the rotating rod 32, to which a contact piece 34 is embedded inside the mounting bracket 33, to which a guide wheel 36 is mounted, and the rotating rod 32 and the mounting bracket 33 are movably connected, and the contact piece 34 is movably connected to the guide wheel 36 via a central shaft; A friction plate is laid on one side of the contact piece 34 close to the guide wheel 36, and the friction plate is attached to the surface of the guide wheel 36. A friction strip 35 is connected to the other side of the guide wheel 36, and the friction strip 35 is connected to the other side of the friction strip 35 through a central shaft. There are two groups of rotating rod 32, mounting bracket 33, contact piece 34, friction strip 35 and guide wheel 36, and each group of mounting bracket 33, contact piece 34 and guide wheel 36 has two. The interior of the guide wheel 36 is set to be concave, and the polyethylene fishing line 27 is embedded in the interior of the guide wheel 36. The two groups of guide wheels 36 wrap the polyethylene fishing line 27. The two mounting brackets 33 and the friction strip 35 are connected by a connecting strip. The rotation of the mounting bracket 33 follows the free change of the inclination angle of the polyethylene fishing line 27.

[0027] When a multi-angle tensile test is performed, first, the mounting bracket 33 and the contact piece 34 are deflected by the rotating rod 32. When the mounting bracket 33 and the contact piece 34 are deflected, the guide wheel 36 is driven to deflect. When the guide wheel 36 is deflected, the polyethylene fishing line 27 embedded in the guide wheel 36 will be twisted to varying degrees due to the deflection. Based on such an environment, the lifting frame 18 is raised, driving the polyethylene fishing line 27 to perform a tensile test. Secondly, during the stretching process, the angle of the rotating rod 32 is continuously changed to achieve stretching in different environments. In addition, when the guide wheel 36 is driven, the rotation of the guide wheel 36 can rub the embedded polyethylene fishing line 27. The wear resistance can be tested by friction. Stretching can also be performed in such an environment. Finally, the rotation of the guide wheel 36 and the friction between the contact piece 34 will generate a large amount of heat, and the heat causes the temperature of the guide wheel 36 to be increased, thereby simulating the process of fishing line release. In summary, this application occupies less space in the test of the polyethylene fishing line 27, and can test the entire fishing line, the test is more comprehensive, can well simulate the real environment, and the test results are more accurate.

[0028] An implementation method of a wear resistance testing device for polyethylene monofilament fishing line, S1, first fix one end of the polyethylene fishing line 27 on the first clamping piece 26, pass the polyethylene fishing line 27 through the first limiting wheel 22 and the second limiting wheel 25 at one time, and fix the other end of the polyethylene fishing line 27 on the second clamping piece 26, so that the polyethylene fishing line 27 is in a straight state; S2, the driving motor 15 starts to work and drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 drives the lifting frame 18. When the lifting frame 18 rises, the polyethylene fishing line 27 is stretched. The strength is further tested by the stretching height and the state of the polyethylene fishing line 27. After stretching a certain distance, the lifting frame 18 starts to descend until it descends to the initial state, and the changes of the polyethylene fishing line 27 after stretching are observed; S3, then, the motor drives the rotating rod 32 to rotate, which drives the angle of the mounting bracket 33 and the contact piece 34 to deflect, and then the guide wheel 36 also deflects synchronously. The deflection of the guide wheel 36 drives the polyethylene fishing line 27 to bend. According to the different deflection directions and different deflection angles on the left and right, the strength test of the polyethylene fishing line 27 in the actual environment is simulated; S4, finally, the guide wheel 36 is driven to rotate, and single-point friction is performed on the contact position between the guide wheel 36 and the polyethylene fishing line 27 to test the wear resistance of the polyethylene fishing line 27. Then, heat is generated by friction between the rotation of the guide wheel 36 and the contact piece 34 to simulate the effect of heat on the polyethylene fishing line 27 in a real environment.
