Description

Technical Field

[0001] This utility model relates to the field of nylon fishing net flexibility testing technology, specifically a nylon fishing net flexibility testing device. Background Technology

[0002] Industries such as fisheries and aquaculture have clear quality standards for nylon fishing nets, with flexibility being a crucial indicator. Testing flexibility helps companies produce products that meet industry standards, avoiding legal risks and economic losses due to quality issues.

[0003] In patent publication CN113203630A, this invention provides a fishing net toughness testing device, belonging to the technical field of processing equipment for fishing net production. This fishing net toughness testing device includes a working box body, a brake cylinder, and a servo motor. The servo motor is fixedly connected to the top of the working box body, and the brake cylinder is fixedly connected to the top of the servo motor. This device can stretch the fishing net to its maximum extent to test the overall toughness of the net. This device can not only stretch the fishing net into a casting shape, but also ensure that the direction of the force is along the inclined plane of the mounting plate during the tensile process, resulting in high stability and providing a certain degree of protection for the fishing net during the testing process.

[0004] Existing nylon fishing net flexibility testing devices suffer from several drawbacks. When repeatedly bending the nylon fishing net to test its flexibility, the rotating mechanism within the device rotates repeatedly, generating friction that can lead to mechanical fatigue over time, affecting the device's lifespan. Furthermore, the existing fixing mechanism is difficult to adjust due to the varying sizes of the nylon fishing net samples, making it unsuitable for testing nets of different sizes. Additionally, the existing devices typically fix the net samples on the edges, leaving the area near the bending point unsecured during bending. This results in the middle of the net bulging upwards during bending, impacting the accuracy of the flexibility test.

[0005] To address the aforementioned issues, a device for testing the flexibility of nylon fishing nets is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Example 1

[0024] Please see Figures 1 to 4 This utility model discloses a nylon fishing net flexibility testing device, comprising a testing device base plate 1. Two sets of support columns 2 are symmetrically arranged on the top of the testing device base plate 1, and the support columns 2 are fixedly connected to the testing device base plate 1. An electric telescopic rod 3 is fixedly connected to the top of the support columns 2, and a folding and rotating assembly 4 is fixedly connected to the output end of the electric telescopic rod 3. The folding and rotating assembly 4 includes a connecting crossbar 401, and the connecting crossbar 401 is fixedly connected to the electric telescopic rod 3. A rotating support 402 is fixedly connected to the end of the connecting crossbar 401, and a folding shaft 403 is nested inside the rotating support 402. A folding plate 5 is fixedly connected to the side of the folding shaft 403, and a nylon fishing net fixing assembly 6 is installed on the top of the folding plate 5. The nylon fishing net fixing assembly 6 includes an insertion port 601, and the insertion ports 601 are evenly spaced on the top of the folding plate 5.

[0025] The inner wall of the rotating support 402 is rotatably connected with ball bearings 405, and the ball bearings 405 are arranged in a ring array about the inner wall of the rotating support 402. The ball bearings 405 are slidably connected to the folding shaft 403. The ball bearings 405 are used to reduce the friction between the rotating support 402 and the folding shaft 403. The top of the rotating support 402 is fixedly connected with a lubricating oil adding pipe 406, and the lubricating oil adding pipe 406 is connected to the rotating support 402. The top end of the lubricating oil adding pipe 406 is threadedly connected with a threaded sealing cap 407. The interior of the rotating support 402 is filled with lubricating oil. The outer wall of the rotating support 402 is fixedly connected with an observation window 404, and the observation window 404 is used to observe the liquid level of the lubricating oil inside the rotating support 402.

[0026] The nylon fishing net, which needs to be tested for flexibility, is fixed to the upper surface of two folding plates 5 through the nylon fishing net fixing component 6. Then, the electric telescopic rod 3 is activated. The output ends of the electric telescopic rods 3 on both sides move the connecting crossbars 401 to the middle position. The two folding plates 5 are connected together by hinges to form a rotating structure. When the connecting crossbars 401 on both sides are pushed inward, the middle position of the two folding plates 5 bends downward under its own weight and pushing action, thus bending the nylon fishing net fixed on its upper surface. While bending, the bending point of the nylon fishing net is observed and the state of the bending point of the nylon fishing net is recorded after bending ten, twenty, thirty times, etc., in order to obtain the flexibility performance of the nylon fishing net.

[0027] During the bending process, the folding plate 5, along with the folding shaft 403, rotates inside the rotating support 402. The ball bearings 405 located between the two can convert the sliding friction into rolling friction, thereby reducing the friction between the rotating support 402 and the folding shaft 403 when they are pulled back, thus reducing wear. The inner cavity of the rotating support 402 is filled with lubricating oil, which can be applied outwards to the contact area with the folding shaft 403 through the ball bearings 405, further reducing friction. The amount of lubricating oil inside can be observed in real time through the observation window 404. When the amount is insufficient, it can be added through the lubricating oil adding pipe 406.

[0028] Insertion block 602 is inserted into the inside of insertion port 601, and insertion post 603 is fixedly connected to the top of insertion block 602. Fixing pressure block 604 is fixedly connected to the side of insertion post 603. Insertion block 602 and insertion post 603 are symmetrically arranged in twos about the vertical central axis of fixing pressure block 604. Insertion block 602 is shaped like a gyroscope with thin ends and thick middle. Silicone pressure block 605 is fixedly connected to the bottom of fixing pressure block 604, and limit pressure grooves 606 are equally spaced on the bottom of silicone pressure block 605.

[0029] After laying the nylon fishing net to be tested on the top surface of the two folded plates 5, insert blocks 602 can be inserted into the corresponding slots 601 at the four corners of the nylon fishing net sample, so that the silicone pressure block 605 presses on the fishing net, and the limiting pressure groove 606 is locked at the top of the nylon fishing net line to limit and fix it. Multiple slots 601 are evenly spaced on the upper surface of the folded plate 5. The insert blocks 602 can be inserted into the corresponding slots 601 according to the size of the nylon fishing net sample to fix it, so as to be applicable to samples of different sizes. Moreover, the limiting pressure groove 606 can be added near the bend of the two folded plates 5 to press and limit the fishing net, so as to prevent the middle position of the fishing net from bulging upward during the bending process, and to ensure that the testing position of the fishing net bends inward with the folded plate 5, thereby facilitating the testing results.
