Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material testing technology, specifically relating to a tensile device for testing the strength of fishing net lines used in fishing net production. Background Technology
[0002] The main raw materials for fishing nets include synthetic fibers such as nylon, polyethylene, and polyester. These materials possess high strength, corrosion resistance, and wear resistance, making them suitable for long-term use in water. The raw materials are processed by a drawing machine, drawing them into fine filaments, which are the basic materials for fishing net production. The quality of the filament drawing directly affects the strength and durability of the fishing net. A heat treatment process fixes the knots, improving the net's strength and stability. Testing the tensile strength of the net ensures it can withstand a certain amount of tension without breaking.
[0003] In the common process of testing fishing net lines, the tensile strength of the fishing net is tested by stretching the fishing net line to ensure that it can withstand a certain amount of tension. However, in addition to testing the tensile performance of the fishing net line, the impact of fish inside the fishing net should also be simulated to test the impact resistance of the fishing net line and determine the number of impacts the fishing net line can withstand, so as to better determine the number of impacts the fishing net line can withstand and its service life. Utility Model Content
[0004] The technical problem to be solved by this utility model is that existing equipment is unable to detect fishing net lines by only testing their tensile strength, without testing their impact resistance or determining the number of impacts they withstand, thus making it impossible to determine the service life of the fishing net lines.
[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a tensile device for testing the strength of fishing net lines used in fishing net production is provided, including a drive box. Reserved channels are provided on both the left and right sides of the top surface of the drive box. A first detection plate is provided on the left side of the top surface of the drive box, and a second detection plate is provided on the right side of the top surface of the drive box. Both the first and second detection plates are located inside the reserved channels. Slider blocks are fixedly connected to the bottom of the front and rear sides of both the first and second detection plates. The sliders are slidably connected to the drive box. A reciprocating device is provided on the left side of the first detection plate, and a moving device is provided on the second detection plate. Both the reciprocating device and the moving device are located inside the drive box.
[0006] The above technical solution uses a moving device to move the second detection plate, which in turn allows the first hook and the tension gauge to work together to detect the tensile strength of the fishing net line. The reciprocating device drives the first detection plate to move back and forth, which detects the impact resistance of the fishing net line and determines the number of impacts it can withstand.
[0007] Furthermore, the reciprocating device includes a first motor, which is fixedly connected to a drive box. A turntable is fixedly connected to the output end of the first motor. A rod is fixedly connected to the front side of the turntable. A movable plate is provided on the front side of the turntable. An arc-shaped channel is provided on the front side of the movable plate. The arc-shaped channel passes through the movable plate. The arc-shaped channel and the rod are correspondingly arranged, and the rod is located inside the arc-shaped channel.
[0008] Furthermore, a first connecting rod is fixedly connected to the middle left side of the movable plate, and a second connecting rod is fixedly connected to the middle right side of the movable plate. The second connecting rod is fixedly connected to the first detection plate. Limit blocks are slidably connected to the outside of both the first and second connecting rods, and the limit blocks are fixedly connected to the drive box.
[0009] The above technical solution uses a first motor to drive the turntable and the insertion rod to rotate. The insertion rod and the arc-shaped channel on the moving plate work together to drive the moving plate to move back and forth, which in turn drives the first detection plate to move back and forth. This is used to detect the impact resistance of the fishing net line under non-extreme conditions and to determine the number of impacts the fishing net line can withstand.
[0010] Furthermore, the mobile device includes a second motor, which is fixedly connected to a drive box. A drive gear is fixedly connected to the output end of the second motor, and a gear rod meshes with the top of the drive gear. The gear rod is fixedly connected to a second detection plate.
[0011] The above technical solution uses a second motor to drive a drive gear to rotate, and the meshing of the drive gear and gear rod drives the second detection plate to move, which is used to cooperate with the tensile tester to detect the tensile performance and strength of the fishing net line.
[0012] Furthermore, a tension gauge is fixedly connected to the top right side of the first detection plate, a first hook is fixedly connected to the top left side of the second detection plate, and a second hook is fixedly connected to the side of the first and second detection plates that are close to each other. The second hook is located below the first hook and the tension gauge.
[0013] Furthermore, a control panel is fixedly connected to the center of the front of the drive box, a fastener is fixedly connected to the center of the left side of the drive box, and a counter is fixedly connected to the right side of the fastener. The counter and the first connecting rod are correspondingly arranged.
[0014] The above technical solution determines the tensile strength and resistance of the fishing net line by reading the tension gauge, and determines the number of impacts the fishing net line can withstand by moving the moving plate of the first connecting rod to press the counter.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention features a moving device located on the right side inside the drive box. This moving device moves the second detection plate, allowing the first hook and the tension gauge to work together to detect the tensile strength of the fishing net line. A reciprocating device located on the left side inside the drive box drives the first detection plate to move back and forth. With the cooperation of the second hook and the counter, the impact resistance of the fishing net line is detected, and the number of impacts the fishing net line withstands is determined.

The second hook 12 is located below the first hook 11 and the tension gauge 10. A slider 13 is fixedly connected to the bottom front and rear sides of the first detection plate 2 and the second detection plate 3. The slider 13 is slidably connected to the drive box 1. A reciprocating device 4 is provided on the left side of the first detection plate 2.
[0025] The reciprocating device 4 includes a first motor 401, which is fixedly connected to the drive box 1. A turntable 402 is fixedly connected to the output end of the first motor 401. A rod 403 is fixedly connected to the front circumferential side of the turntable 402. The rod 403 is used to cooperate with the arc-shaped channel 405 to move the moving plate 404 left and right. The moving plate 404 is provided on the front side of the turntable 402. The arc-shaped channel 405 is provided on the front side of the moving plate 404.
