A wear resistance testing device and implementation method for polyethylene monofilament fishing line

Abstract

The present invention discloses a wear-resistant testing device and an implementation method for a polyethylene monofilament fishing line, and relates to the technical field of polyethylene wire testing. Nowadays, when a fishing line is subjected to a strength test, due to the long length of the entire fishing line, only one section can be taken for testing. Such a testing method cannot well reflect the overall strength of the fishing line. Secondly, there is a large deviation between such a test and the tension of the fishing line applied to fishing in reality. Cutting off a section for strength testing cannot well reflect the strength of the fishing line in a real state. The present invention can fold the polyethylene fishing line in half by providing an upper pulling rod and a first limiting wheel as well as a lower pulling rod and a second limiting wheel. After being folded in half, the polyethylene fishing line is stretched, and the stretching force can cover the entire fishing line, and the space utilization is also smaller. Secondly, on this basis, a real environment is simulated, and a multi-directional test is performed, and the test results are more accurate.

Description

Technical Field

[0001] The invention relates to the technical field of polyethylene wire testing, in particular to a wear resistance testing device and an implementation method for polyethylene monofilament fishing lines. Background Art

[0002] Polyethylene monofilament fishing line generally refers to fishing line made from polyethylene, which has a certain strength and wear resistance, 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, driving the fishing line to rub against the detection medium for detection, and after a period of reciprocating motion, the fishing line is removed, and the anti-curling property of the fishing line is judged according to the degree of curling of the fishing line, and the wear resistance of the fishing line can be judged by the degree of wear 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 fixed on the front of the bracket, a wheel fixed on the output end of the motor, an active rod fixed on the wheel, a fixed rod provided on the inner side of the bracket, a fishing line provided on the fixed rod, one end of the fishing line is fixedly connected to the active rod, and a weight block is fixed to 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, active rod, fixed rod, motor and 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 testing time, facilitating improving the use effect and increasing the practicality of the device.

[0005] Nowadays, when testing the strength of fishing lines, the strength is tested by pulling. However, due to the long length of the fishing line as a whole, the test requires a larger place. Therefore, only one section can be tested during the test. This test method cannot well reflect the overall strength of the fishing line. Secondly, there is a lot of deviation between this test and the pulling force applied to the fishing line in reality. Cutting off a section for strength testing cannot well reflect the strength of the fishing line in its actual state.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0036] Combine Figures 1-8 The present invention provides a wear resistance testing device for polyethylene monofilament fishing line, comprising a test seat 11, a threaded rod 12 and a guide rod 13 being mounted on the upper surface of the test seat 11, the threaded rod 12 and the test seat 11 being rotatably connected, the top ends of the threaded rod 12 and the guide rod 13 being connected to a top plate 14, a drive motor 15 being connected to the top surface of the top plate 14, an output end of the drive motor 15 being connected to the threaded rod 12, a side plate 17 being connected to the side of the test seat 11, a lifting frame 18 being sleeved on the outer surface of the threaded rod 12, and a cover plate 16 being connected to the top surface of the lifting frame 18;

[0037] When testing the wear resistance of the polyethylene fishing line 27, the test is conducted by better simulating the fishing line usage environment. In order to test the entire fishing line, the polyethylene fishing line 27 is bent and then stretched uniformly after bending. Then, the polyethylene fishing line 27 is restored after the stretching. The state of the polyethylene fishing line 27 can be observed to further determine the strength of the polyethylene fishing line 27. The specific operation is as follows:

[0038] The lifting frame 18 is provided with a pulling assembly 2, which includes an upper pulling rod 21. The outer surface of the upper pulling rod 21 is movably connected to a first limiting wheel 22. A lower pull rod 24 is also provided on the test seat 11. 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. There are two clamping pieces 26, one of which is connected to the lifting frame 18 and the other is connected to the test seat 11. The first limiting wheel 22 and the second limiting wheel 25 are embedded with polyethylene. The polyethylene fishing line 27 and the clamping piece 26 are used to fix the two ends of the polyethylene fishing line 27. There are two groups of upper pulling rods 21, and each group of upper pulling rods 21 is provided with a first limiting wheel 22. There are also two groups of lower pull rods 24, and each group of lower pull 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.

[0039] 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, the upper pulling rod 21 and the first limiting wheel 22 are followed, among which 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 polyethylene fishing line 27 is stretched. In the stretching stage, it is convenient to better distribute the applied force. At this time, the upper pulling rod 21 and the first limiting wheel 22 are kept in rotational 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. Through rotation, all parts of the polyethylene fishing line 27 can be stretched, so that when testing the tensile strength, the applied force is more uniform.

[0040] 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.

[0041] In order to better simulate the working environment of the polyethylene fishing line 27, it is necessary to stretch it not only in the vertical direction but also at different angles to better test its strength, which is specifically manifested in the following aspects:

[0042] The test seat 11 is also fixedly connected to a mounting plate 23, to which a simulation component 3 is connected. The simulation component 3 includes a connecting plate 31. A rotating rod 32 is connected to the side of the connecting plate 31 away from the mounting plate 23. The end of the rotating rod 32 is connected to a mounting bracket 33. A contact piece 34 is embedded in the mounting bracket 33. A guide wheel 36 is mounted on the contact piece 34. The rotating rod 32 and the mounting bracket 33 are movably connected. The contact piece 34 is movably connected to the guide wheel 36 via a central shaft.

[0043] 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 rods 32, mounting brackets 33, contact pieces 34, friction strips 35 and guide wheels 36, and each group of mounting brackets 33, contact pieces 34 and guide wheels 36 has two. The interior of the guide wheel 36 is set to a recessed shape, 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.

[0044] When conducting a multi-angle tensile test, 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. Under such an environment, the lifting frame 18 is lifted, driving the polyethylene fishing line 27 to undergo a tensile test. Secondly, during the stretching process, the angle of the rotating rod 32 is continuously changed to achieve stretching under 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, and the wear resistance can be tested by friction. Stretching can also be performed under such an environment. Finally, the friction between the rotation of the guide wheel 36 and the contact piece 34 generates a large amount of heat, which increases the temperature of the guide wheel 36, thereby simulating the process of fishing line release.

[0045] In summary, this application occupies less space when testing 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.

[0046] An implementation method of a wear resistance testing device for polyethylene monofilament fishing line,

[0047] S1, first fix one end of the polyethylene fishing line 27 to 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 to the second clamping piece 26, so that the polyethylene fishing line 27 is in a straight state;

[0048] S2, the driving motor 15 starts to operate, driving 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 of the polyethylene fishing line 27 is further tested by the stretched height and the state of the polyethylene fishing line 27. After stretching a certain distance, the lifting frame 18 begins to descend until it returns to its initial position, and the changes in the polyethylene fishing line 27 after stretching are observed.

[0049] S3, the motor then drives the rotating rod 32 to rotate, causing the mounting bracket 33 and the contact piece 34 to deflect. The guide wheel 36 also deflects synchronously. The deflection of the guide wheel 36 causes the polyethylene fishing line 27 to bend. The different deflection directions and angles to the left and right simulate the strength test of the polyethylene fishing line 27 in an actual environment.

[0050] 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 guide wheel 36 and the contact piece 34 to simulate the effect of heat on the polyethylene fishing line 27 in a real environment.
