[0041] The working principle of this utility model:
[0042] When testing plastic products, first place the plastic products at a suitable position on the top of the testing platform 2, then bring the friction head of the linear abrasion tester 1 into contact with the plastic products and add appropriate counterweights. Then start the dual-head motor 501 to drive the screw 502 to rotate. During the rotation of the screw 502, it will drive the push plate 503 to move on the surface of the sliding column 10. The push plate 503 will drive the positioning plate 4 and the pressing device to move synchronously and approach the plastic products. When the positioning plate 4 contacts the plastic products, stop the dual-head motor 501 and the positioning plate 4 will no longer move, thus positioning both sides of the plastic products.
[0043] During its movement, the pressing device will compress the extrusion device 9, causing the pressing device to move downward and press the plastic product. When the contact plate 703 moves to the appropriate position, the inclined surface of the contact plate 703 will contact the inclined surface of the extrusion block 903 and compress it. The compressive force generated at this time will push the contact plate 703 to move downward. The contact plate 703 will drive the pressing plate 701 to move downward synchronously through the limiting post 702 and compress the spring 704. After the pressing plate 701 descends to the appropriate position, it will contact the plastic product and press the plastic product.
[0044] When it is necessary to compress plastic products of different sizes, turn the control switch 902. The control switch 902 will drive the double-headed screw 901 to rotate. During the rotation of the double-headed screw 901, it will drive the two extrusion blocks 903 to move synchronously. At the same time, the position of the extrusion blocks 903 is adjusted according to the distance between the two sides of the plastic product, so that the two extrusion blocks 903 move closer or further apart. When the extrusion blocks 903 reach the appropriate extrusion position, stop turning the control switch 902 to complete the adjustment.
[0045] In summary, this abrasion resistance testing device for plastic products, through the coordinated use of support plate 3, positioning plate 4, control components 5, rectangular through hole 6, clamping device 7, support block 8, and extrusion device 9, solves the problem that existing linear abrasion testing machines, when used, require placing the plastic product to be tested on top of the testing table, and after placement, usually require manual clamping to press the plastic product, which is time-consuming and labor-intensive, affecting the efficiency of the test.
