[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the utility model discloses a PE coating friction resistance testing device.

[0025] The utility model provides Figure 1-3The PE coating friction resistance testing device shown includes a base 1, a splint 2 is slidingly provided on the upper surface of the base 1, a first adjustment mechanism is provided below the splint 2, and both splints 2 are moved by the first adjustment mechanism, the upper surface of the base 1 is fixedly connected to a U-shaped plate 3, the lower surface of the U-shaped plate 3 is fixedly connected to a cylinder 4, the output end of the cylinder 4 is fixedly connected to a protective cover 5, the lower end of the protective cover 5 is fixedly connected to a mounting plate 6, the lower surface of the mounting plate 6 is rotatably connected to a rotating rod 7, the lower end of the rotating rod 7 is fixedly sleeved with a first friction block 8, the lower surface of the mounting plate 6 is located at one end of the first friction block 8 and a second friction block 9 is slidingly provided, the upper surface of the mounting plate 6 is provided with a second adjustment mechanism, the second friction block 9 is moved by the second adjustment mechanism, a driving mechanism is provided on one side of the second adjustment mechanism, and the rotating rod 7 is rotated by the driving mechanism.

[0026] An object coated with PE is placed on the upper surface of the base 1. The first friction block 8 is then rotated and rubbed on the PE coating by rotating the rotating rod 7. At the same time, the second friction block 9 is moved left and right to slide and rub against the PE coating, thereby comprehensively testing the wear resistance of the PE coating.

[0027] In order to make objects coated with PE coatings able to be fixed, such as Figure 1-2 As shown, the first adjusting mechanism includes a first screw rod 10, a movable plate 11, a knob 12 and two connecting rods 13. The first screw rod 10 is rotatably connected to the lower surface of the base 1, and the movable plate 11 is threadedly sleeved on the outer surface of the first screw rod 10. The two connecting rods 13 are respectively fixedly connected to the lower surfaces of the two ends of the movable plate 11. The upper ends of the two connecting rods 13 pass through the lower surface of the base 1 and are respectively fixedly connected to the lower surfaces of the corresponding splints 2. The knob 12 is fixedly connected to the lower end of the first screw rod 10.

[0028] Rotate the knob 12 to rotate the first screw rod 10, and then the movable plate 11 can move downward. Next, the two connecting rods 13 can drive the two clamping plates 2 to move downward and fix the object coated with the PE coating.

[0029] In order to make the second friction block 9 slide, Figure 1-2 As shown, the second adjustment mechanism includes two fixed plates 14, a second screw rod 15 and two sliders 16. The two fixed plates 14 are fixedly connected to the upper surface of the mounting plate 6. The second screw rod 15 is rotatably connected between the two fixed plates 14.

A strip hole is opened on the upper surface of the fixed plate 14, and the strip hole matches the slider 16.

[0030] The second screw rod 15 is a reciprocating screw rod, so when it rotates, it can drive the slider 16 to move back and forth, and then the slider 16 can drive the second friction block 9 to rub back and forth on the object to be coated with the PE coating.

[0033] In order to make the second screw rod 15 rotatable, Figure 2 As shown, one end of the second screw rod 15 passes through one side of the corresponding fixing plate 14 and is fixedly connected to one output end of the dual-axis motor 17 .

[0034] When the dual-axis motor 17 is started, the second screw rod 15 can rotate accordingly.

[0035] Finally, in order to prevent the splint 2 from being excessively squeezed, Figure 1-2 As shown, rubber pads 20 are fixedly connected to the lower surfaces of the two clamping plates 2 .

[0036] The rubber pad 20 can prevent the clamping plate 2 from being excessively squeezed.
