Description

Technical Field

[0001] This utility model relates to the field of rubber abrasion resistance testing technology, and in particular to a rubber abrasion resistance testing device for plastic products. Background Technology

[0002] By simulating the mechanical wear of plastic surfaces by erasers or other friction media in actual use, the wear degree of the material can be quantified. By comparing the performance changes before and after friction, the wear resistance level of plastic materials can be evaluated, which can guide product formulation improvement or quality control. This type of equipment is widely used in the automotive, electronics, packaging and other industries, and is of great significance for improving product life and reliability.

[0003] Existing rubber abrasion resistance testing equipment requires the addition of the same weights to test friction under different weights. However, the friction between the material and the rubber may cause the weights to shift through the device, leading to deviations in the test results. Therefore, a device is needed to fix the weights and reduce errors. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rubber abrasion resistance testing device for plastic products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rubber abrasion resistance testing device for plastic products includes a main body of the abrasion resistance testing device, two symmetrical cleaning components mounted on the main body, multiple weights slidably connected to the main body, two symmetrical openings on the main body, a movable block slidably connected to each opening, a threaded rod threaded to one end of each movable block, both threaded rods rotatably connected inside the main body, a bevel gear fixedly mounted to one end of each threaded rod, a rotating shaft rotatably connected inside the main body, a bevel gear fixedly mounted to one end of the rotating shaft, both bevel gears meshing with each other, a stabilizing block fixedly mounted on each of the two movable blocks, and a tensioning component mounted on each of the two stabilizing blocks.

[0007] Preferably, the tensioning component includes multiple sliding grooves at the upper end of the stabilizing block, each of the multiple sliding grooves having a lifting block slidably connected therein, the lifting blocks and the sliding grooves having a spring fixedly installed together, one end of each of the multiple lifting blocks having an extension block fixedly installed therein, and the extension block having a limiting block fixedly installed therein.

[0008] Preferably, the cleaning assembly includes two mutually symmetrical cleaning structures. Each cleaning structure includes a rack fixedly installed on the main body of the abrasion resistance testing equipment. A second rotating shaft is rotatably connected to the main body of the abrasion resistance testing equipment. A spur gear is fixedly installed on the second rotating shaft, and the spur gear meshes with the rack. A third rotating shaft is rotatably installed on the main body of the abrasion resistance testing equipment. A turntable is fixedly installed on the third rotating shaft. Multiple brushes are fixedly installed at the lower end of the turntable. The third rotating shaft and the second rotating shaft are connected by a belt drive assembly.

[0009] Preferably, the belt drive assembly includes pulleys fixedly mounted on one end of shaft three and shaft two, and the belt body is mounted on both pulleys for rotation.

[0010] Preferably, a knob is fixedly installed at one end of the rotating shaft, and a rubber sleeve is threaded onto the knob.

[0011] Preferably, a plurality of pads are fixedly installed at the lower end of the main body of the wear resistance testing equipment, and the lower ends of the plurality of pads are all provided with anti-slip patterns.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by rotating the shaft, the second bevel gear drives the first bevel gear to rotate, which in turn drives the threaded rod and causes the moving block to move, thereby driving the stabilizing block to clamp the weight. It can be adapted to weights of different specifications. At the same time, through the spring and the extension block, multiple stacked weights can be fixed, further improving practicality.

[0013] 2. The movement of the material causes the rack to drive the spur gear to rotate, and the belt drive assembly causes the rotating shaft to rotate, thereby driving the turntable and brush to rotate. Therefore, the friction points of the plastic material can be cleaned, making it convenient for staff to observe. Attached Figure Description

[0019] Reference Figures 1-3 A rubber abrasion resistance testing device for plastic products includes an abrasion resistance testing device body 1. The abrasion resistance testing device body 1 is the prior art, which has a position for placing weights 2 and a device that allows the plastic material to move laterally. The lower end of the abrasion resistance testing device body 1 is fixedly installed with multiple pads, and the lower end of each pad is installed with anti-slip texture. With the pads and anti-slip texture, the operator can place the device stably in the designated position. Two mutually symmetrical cleaning components are installed on the abrasion resistance testing device body 1.

[0020] The cleaning assembly includes two symmetrical cleaning structures. Each cleaning structure includes a rack 13 fixedly mounted on the main body 1 of the abrasion testing equipment. A second rotating shaft 14 is rotatably connected to the main body 1 of the abrasion testing equipment. A spur gear 15 is fixedly mounted on the second rotating shaft 14 and meshes with the rack 13. A third rotating shaft 16 is rotatably mounted on the main body 1 of the abrasion testing equipment. A turntable 17 is fixedly mounted on the third rotating shaft 16. Multiple brushes 18 are fixedly mounted on the lower end of the turntable 17. The rack 13 drives the spur gear 15 to rotate due to the lateral reciprocating motion of the plastic placement platform on the main body 1 of the abrasion testing equipment.

[0021] This drives the second shaft 14 to rotate, and with the cooperation of the belt drive assembly, drives the third shaft 16 to rotate, which in turn drives the turntable 17 and the brush 18 to rotate, cleaning the friction points on the plastic. The third shaft 16 and the second shaft 14 are connected by a belt drive assembly. The belt drive assembly includes pulleys 19 fixedly installed on one end of the third shaft 16 and the second shaft 14. The two pulleys 19 are rotatably mounted on the belt body 20. The rotation of the second shaft 14 drives the pulleys 19 to rotate, which in turn drives the belt body 20 to rotate, thereby driving the other pulley 19 to rotate. Multiple weights 2 are slidably connected on the main body 1 of the abrasion resistance testing equipment. The main body 1 of the abrasion resistance testing equipment has two symmetrical openings 3. Moving blocks 4 are slidably connected in both openings 3. One end of each moving block 4 is threadedly connected to a threaded rod 5. Both threaded rods 5 are rotatably connected inside the main body 1 of the abrasion resistance testing equipment.

[0022] Two threaded rods 5 are each fixedly mounted with a bevel gear 6 at one end. A rotating shaft 7 is rotatably connected inside the main body 1 of the wear resistance testing equipment. A knob 21 is fixedly mounted at one end of the rotating shaft 7. A rubber sleeve is threaded onto the knob 21. By rotating the knob 21, the rotating shaft 7 can be easily rotated to achieve stable operation. The rubber sleeve can be quickly removed and replaced after prolonged use. A bevel gear 8 is fixedly mounted at one end of the rotating shaft 7. Both bevel gears 6 mesh with bevel gear 8. Each movable block 4 is fixedly equipped with a stabilizing block 9, and each of the two stabilizing blocks 9 is equipped with a tensioning component. The tensioning component includes multiple sliding grooves at the upper end of the stabilizing block 9, and each sliding groove is slidably connected with a lifting block 10. The lifting block 10 and the sliding groove are both fixedly equipped with a spring 11. One end of each lifting block 10 is fixedly equipped with an extension block 12, and a limiting block is fixedly installed inside the extension block 12. With the above structure, this device can clamp weights 2 of different specifications and stabilize multiple stacked weights 2.

[0023] The working principle of this invention is as follows: By adding weights 2 to the main body 1 of the abrasion resistance testing equipment, the operator rotates the knob 21, which drives the rotating shaft 7 to rotate, thereby driving the bevel gear 8 to rotate, and driving the meshing bevel gear 6 to rotate, thus driving the threaded rod 5 to rotate, so that the moving block 4 clamps the weights 2. By pulling the extension block 12, it is raised until it reaches the designated position. Then, by limiting the extension block 12, it can stably fix the multiple stacked weights 2. Then, the main body 1 of the abrasion resistance testing equipment is opened, and the lateral reciprocating movement of its placement platform drives the rack 13 on it to drive the spur gear 15 to rotate, thereby driving the rotating shaft 14 to rotate. With the cooperation of the belt drive assembly, the rotating shaft 16 rotates, driving the turntable 17 and the brush 18 to rotate, so that the brush 18 cleans the plastic surface, meeting the testing needs of the operator.
