Description

Technical Field

[0001] This invention belongs to the technical field of steel-plastic composite belts, specifically relating to a durability testing device for steel-plastic composite belts. Background Technology

[0002] Steel-plastic composite tape is a composite product made by extruding specially made micro high-strength galvanized iron wire wrapped with anti-aging and acid- and alkali-resistant polyethylene resin, and adding a certain proportion of anti-aging agents, antioxidants and light-shielding agents. It has advantages such as high tensile strength, small deformation, long service life, low cost, convenient construction and good pull-out resistance. The main load-bearing element of steel-plastic composite tape is high-strength galvanized iron wire, and the tensile strength of the tape can be changed by adjusting the diameter and number of steel wires according to the actual needs of the project.

[0003] Durability tests are required during the production of steel-plastic composite belts. The fatigue durability of the steel-plastic composite belt is judged by whether cracks, delamination or fractures appear under repeated impacts. When performing durability tests on multiple parts of a steel-plastic composite belt, if a fracture occurs, the fractured part will continue to move and its direction of movement will be changed by gravity and other factors. Operators need to manually adjust the direction of movement of the steel-plastic composite belt, which is a rather cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to provide a durability testing device for steel-plastic composite belts, which solves the problem in the existing technology that when multiple parts of a steel-plastic composite belt are tested for durability, if a break occurs, the broken part will continue to move and its direction of movement will change due to gravity and other factors. This requires the operator to manually adjust the direction of movement of the steel-plastic composite belt, which is a rather cumbersome operation.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A durability testing device for steel-plastic composite strips includes:

[0007] A workbench, the top surface of which is equipped with a winding mechanism for winding up the steel-plastic composite strip;

[0008] A fixing mechanism is provided on the top surface of the workbench and is used to fix the left and right ends of the steel-plastic composite belt to be tested.

[0009] Electric slide rails are symmetrically arranged above the worktable. The electric slide rails facilitate the movement of the steel-plastic composite belt to unfold the steel-plastic composite belt.

[0010] A drive mechanism is provided above the worktable and is used to clamp and fix the unbroken portion of the steel-plastic composite belt.

[0011] In a preferred embodiment, the top surface of the workbench is fixedly provided with symmetrical support plates, and electric slide rails are installed on the sides of the support plates that are close to each other. Electric sliders adapted to the electric slide rails are provided inside the electric slide rails. A viewing window is installed on the front of the support plate, and a top plate is fixedly provided on the top surface of the support plate.

[0012] In a preferred embodiment, the winding mechanism includes a servo motor, a fixed plate, and a guide frame. The servo motor is positioned above the worktable, and symmetrical fixed plates are fixedly mounted on the top surface of the worktable. The front of the fixed plates is fixedly connected to the housing of the servo motor. The output end of the servo motor passes through the fixed plates and is rotatably connected to them. A guide frame is positioned above the fixed plates, and connecting rods are fixedly mounted at both ends of the guide frame. The other end of each connecting rod is fixedly connected to the fixed plate. A guide groove is provided through the side of the guide frame, and the steel-plastic composite belt passes through the guide groove and through the guide frame.

[0013] In a preferred embodiment, an impact mechanism is provided on the bottom surface of the top plate. The impact mechanism includes a first cylinder and a push block. The first cylinder is fixedly installed on the bottom surface of the top plate, and the push block is fixedly provided on the bottom surface of the output end of the first cylinder.

[0014] In a preferred embodiment, a fixing mechanism is provided between the workbench and the top plate. The fixing mechanism includes a second cylinder, a pressure plate, and a clamping block. Symmetrical second cylinders are fixedly installed on the bottom surface of the top plate. A pressure plate is fixedly installed on the bottom surface of the output end of the second cylinder. A clamping block is provided directly below the pressure plate. The bottom surface of the clamping block is fixedly connected to the top surface of the workbench.

[0015] In a preferred embodiment, the driving mechanism includes a movable plate, an electromagnet, a movable box, a fixed rod, a rope, an iron block, a limiting plate, a return spring, and protrusions. A movable plate is fixedly mounted on one side of the electric sliders that are close to each other. An electromagnet is fixedly mounted on the bottom surface of the movable plate. Symmetrical fixed rods are fixedly mounted between the sides of the supporting plates that are close to each other. Multiple ropes are fixedly mounted between the sides of the fixed rods that are close to each other. Multiple movable boxes are threaded through the outer sides of the ropes and are slidably connected to the movable boxes. A return spring is fixedly mounted on the bottom surface inside each movable box. A limiting plate is fixedly mounted on the other end of the return spring and is slidably connected to the inner wall of the movable box. An iron block is fixedly mounted on the top surface of the limiting plate, and multiple protrusions are fixedly mounted on the top surface of the iron block.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This utility model, by setting a fixing mechanism, moves the steel-plastic composite belt to move the part to be tested to the right below the push block, and controls the second cylinder to drive the pressure plate to move downward so that the pressure plate and the clamping block are in close contact with the steel-plastic composite belt, which can fix the left and right ends of the part to be tested of the steel-plastic composite belt.

[0018] This invention, by setting up an electric slide rail and a drive mechanism, allows for the following process: When the durability test of the steel-plastic composite belt is completed, the electromagnet is activated to attract an iron block. The iron block moves upward, causing the protrusion to move upward as well. The iron block, in conjunction with the electromagnet, clamps and fixes the steel-plastic composite belt. The protrusion increases the friction between the steel-plastic composite belt and the iron block. The electric slide rail, in conjunction with the electric slider (not shown in the figure), drives the drive mechanism to move, thereby moving the steel-plastic composite belt until the next part to be tested is directly below the push block. This replaces manual operation, improving work efficiency. Even if the steel-plastic composite belt breaks, it does not affect the drive mechanism's ability to move the steel-plastic composite belt in conjunction with the electric slide rail.

[0034] Please see the appendix Figure 1 As shown, this utility model provides a durability testing device for steel-plastic composite belts, including: a workbench 100, a fixing mechanism 400, an electric slide rail 500, and a drive mechanism 600.

[0035] In a preferred embodiment, please refer to Figure 1 The top surface of the workbench 100 is fixedly equipped with symmetrical support plates 101. The front of the support plate 101 is equipped with a viewing window 102, which allows the staff to observe the test results of the steel-plastic composite belt. The top surface of the support plate 101 is fixedly equipped with a top plate 103.

[0036] In a preferred embodiment, please refer to Figure 2A winding mechanism 200 is provided on the top surface of the workbench 100. The winding mechanism 200 consists of a servo motor 201, a fixed plate 202, and a guide frame 203. The servo motor 201 is located above the workbench 100. Symmetrical fixed plates 202 are fixedly installed on the top surface of the workbench 100. The front of the fixed plate 202 is fixedly connected to the housing of the servo motor 201. The output end of the servo motor 201 passes through the fixed plate 202 and is rotatably connected to the fixed plate 202. A winding roller is fixedly installed at the end of the output end of the servo motor 201. The winding roller is located away from the servo motor. One end of the machine 201 is rotatably connected to the fixed plate 202 via a bearing. The servo motor 201 drives the winding roller to rotate, which can wind up the steel-plastic composite belt. A guide frame 203 is provided above the fixed plate 202. Connecting rods are fixedly provided at the front and rear ends of the guide frame 203, and the other end of the connecting rods is fixedly connected to the fixed plate 202. A guide groove is provided through the side of the guide frame 203. The steel-plastic composite belt passes through the guide groove and passes through the guide frame 203.

[0037] In a preferred embodiment, please refer to Figures 1 to 3 An impact mechanism 300 is provided on the bottom surface of the top plate 103. The impact mechanism 300 consists of a first cylinder 301 and a push block 302. The first cylinder 301 is fixedly installed on the bottom surface of the top plate 103. The push block 302 is fixedly installed on the bottom surface of the output end of the first cylinder 301. By controlling the first cylinder 301 to drive the push block 302 to move up and down, the steel-plastic composite belt can be repeatedly impacted. The fatigue resistance and durability of the steel-plastic composite belt can be judged by whether cracks, delamination or fractures occur.

[0038] In a preferred embodiment, please refer to Figures 1 to 3 The top surface of the workbench 100 is provided with a fixing mechanism 400, which consists of a second cylinder 401, a pressure plate 402 and a clamping block 403. The bottom surface of the top plate 103 is fixedly installed with symmetrical second cylinders 401. The bottom surface of the output end of the second cylinder 401 is fixedly provided with a pressure plate 402. The clamping block 403 is provided directly below the pressure plate 402. The bottom surface of the clamping block 403 is fixedly connected to the top surface of the workbench 100.

[0039] In this embodiment, the fixing mechanism 400 is symmetrically arranged on the left and right sides of the impact mechanism 300. The bottom surface of the pressure plate 402 and the top surface of the clamping block 403 are rough surfaces. The steel-plastic composite belt is moved to move the part to be tested to the right below the push block 302. The second cylinder 401 is controlled to drive the pressure plate 402 to move downward so that the pressure plate 402 cooperates with the clamping block 403 to press the steel-plastic composite belt, which can fix the left and right ends of the part to be tested of the steel-plastic composite belt.

[0040] In a preferred embodiment, please refer to Figures 1 to 3Symmetrical electric slide rails 500 are provided above the workbench 100. Electric slide rails 500 are installed on the side of the support plate 101 that are close to each other. Electric slide rails 500 are provided with electric sliders (not shown in the figure) that are adapted to the electric slide rails 500.

[0041] In a preferred embodiment, please refer to Figures 1 to 4 A drive mechanism 600 is installed above the workbench 100. The drive mechanism 600 consists of a movable plate 601, an electromagnet 602, a movable box 603, a fixed rod 604, a rope 605, an iron block 606, a limit plate 607, a return spring 608, and a protrusion 609. The movable plate 601 is fixedly installed on one side of the electric sliders (not shown in the figure). An electromagnet 602 is fixedly installed on the bottom surface of the movable plate 601. The bottom surface of the electromagnet 602 is slightly higher than the top surface of the steel-plastic composite belt. Symmetrical fixed rods 604 are fixedly installed between the adjacent sides of the support plates 101. Multiple ropes 605 are fixedly installed between the adjacent sides of the fixed rods 604. 5. Multiple movable boxes 603 are provided through the outer side. Two through grooves for ropes 605 are provided through the side of the movable box 603. The ropes 605 are slidably connected to the movable box 603 through the through grooves. A sliding groove is provided inside the movable box 603. A return spring 608 is fixedly provided on the bottom surface of the sliding groove. A limiting plate 607 adapted to the sliding groove is fixedly provided on the other end of the return spring 608. The limiting plate 607 is slidably connected to the inner wall of the movable box 603 through the sliding groove. An iron block 606 is fixedly provided on the top surface of the limiting plate 607. The iron block 606 passes through the movable box 603 to the outside of the movable box 603 and is slidably connected to the movable box 603. Multiple protrusions 609 are fixedly provided on the top surface of the iron block 606.

[0042] In this embodiment, when the durability test of the part to be tested is completed, the electromagnet 602 is activated to attract the iron block 606. The iron block 606 moves upward, causing the limiting plate 607 and the protrusion 609 to move upward. The return spring 608 is extended. The iron block 606, in conjunction with the electromagnet 602, clamps and fixes the steel-plastic composite strip. The protrusion 609 can increase the friction between the steel-plastic composite strip and the iron block 606. The electric slide rail 500, in conjunction with the electric slider (not shown in the figure), can drive the iron block 606 to move. The movement of the iron block 606 drives the moving box 603, the limiting plate 607, the return spring 608, and the protrusion 609 to move. The rope 605 guides the movement of the moving box 603, thereby driving... The steel-plastic composite belt moves until the next part to be inspected moves directly below the push block 302, thus replacing manual operation and improving work efficiency. The electric slide rail 500 drives the electric slider (not shown in the figure) to move in the opposite direction, while reducing the attraction of the electromagnet 602 on the iron block 606, causing the iron block 606 and the protrusion 609 to detach from the steel-plastic composite belt. At this time, the attraction of the electromagnet 602 on the iron block 606 is still sufficient to drive the moving box 603 to move along the surface of the rope 605 until the moving box 603 moves back to its original position. When the steel-plastic composite belt breaks, the drive mechanism 600 can clamp the unbroken steel-plastic composite belt, so as not to affect the drive mechanism 600 cooperating with the electric slide rail 500 to drive the steel-plastic composite belt to move.

[0043] The working principle of this utility model is as follows:

[0044] When in use, the device controls the servo motor 201 to drive the winding roller to rotate and wind up the steel-plastic composite belt. One end of the steel-plastic composite belt passes through the guide frame 203 and unfolds outward until the part to be tested moves directly below the push block 302. The second cylinder 401 is controlled to drive the pressure plate 402 to move downward, so that the pressure plate 402 cooperates with the clamping block 403 to press the steel-plastic composite belt. This can fix the left and right ends of the part to be tested of the steel-plastic composite belt. Controlling the first cylinder 301 to drive the push block 302 to move up and down can repeatedly impact the steel-plastic composite belt. The fatigue resistance and durability of the steel-plastic composite belt can be judged by whether cracks, delamination or fractures appear.

[0045] When the device completes the durability test of the part to be tested, the electromagnet 602 is activated to attract the iron block 606. The iron block 606 moves upward, causing the limiting plate 607 and the protrusion 609 to move upward as well. The return spring 608 is extended. The iron block 606, in conjunction with the electromagnet 602, clamps and fixes the steel-plastic composite belt. The protrusion 609 increases the friction between the steel-plastic composite belt and the iron block 606. The electric slide rail 500, in conjunction with the electric slider (not shown in the figure), can move the iron block 606. The movement of the iron block 606 moves the moving box 603, the limiting plate 607, the return spring 608, and the protrusion 609. The rope 605 guides the movement of the moving box 603, thereby moving the steel-plastic composite belt until the next part to be tested. Move it directly under the push block 302 to replace manual operation, which helps improve work efficiency. The electric slide rail 500 drives the electric slider (not shown in the figure) to move in the opposite direction, while reducing the attraction of the electromagnet 602 on the iron block 606, so that the iron block 606 and the protrusion 609 are separated from the steel-plastic composite belt. At this time, the attraction of the electromagnet 602 on the iron block 606 is still sufficient to drive the moving box 603 to move along the surface of the rope 605 until the moving box 603 moves back to its original position. When the steel-plastic composite belt breaks, the drive mechanism 600 can clamp the unbroken steel-plastic composite belt, so as not to affect the drive mechanism 600 to cooperate with the electric slide rail 500 to drive the steel-plastic composite belt to move. Repeat the above operation to conduct durability tests on multiple parts of a steel-plastic composite belt.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
