Description

Technical Field

[0001] This utility model relates to the field of spray coating testing technology, specifically to an alcohol friction mechanism for spray coating testing. Background Technology

[0002] The alcohol abrasion tester is mainly used for abrasion resistance testing of product surfaces. It is suitable for testing the abrasion resistance of mobile phones, MP3 players, CD players, laptops, and various surface-coated samples, as well as the abrasion life of various product surfaces and printed surfaces. An alcohol abrasion mechanism is required when testing sprayed coatings.

[0003] Traditional alcohol friction mechanisms have certain shortcomings in use. They have limited clamping and fixing effect on the test piece, which can lead to accidental movement of the test piece, thereby reducing the accuracy of the test and limiting the practicality of the alcohol friction mechanism. It can also increase the error in the coating test. Therefore, we propose an alcohol friction mechanism for coating test. Utility Model Content

[0023] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0024] An alcohol friction mechanism for spray coating testing includes a base plate 1, a fixing plate 3 fixedly connected to the top of the base plate 1, a test box 4 fixedly connected to the top of the fixing plate 3, a drive motor 6 mounted on the surface of the base plate 1, a threaded rod 7 fixedly connected to the output end of the drive motor 6, a circular sleeve 19 fixedly connected to the bottom of the fixing plate 3, the threaded rod 7 extending into the circular sleeve 19 and rotatably connected to the circular sleeve 19, a threaded sleeve 8 threadedly connected to the outside of the threaded rod 7, a side plate 9 fixedly connected to the top of the threaded sleeve 8, the side plate 9 extending into the test box 4 and slidably connected to the test box 4, a clamping plate 20 fixedly connected to the side of the side plate 9, a spray coating part 22 abutting inside the clamping plate 20, a fastening bolt 21 threadedly connected to the top of the clamping plate 20, the bottom of the fastening bolt 21 abutting against the surface of the spray coating part 22, and a top groove 12 opened on the top of the test box 4.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, an electric telescopic rod 10 is installed on the top of the test box 4, and an extrusion plate 11 is fixedly connected to the bottom of the electric telescopic rod 10. The extrusion plate 11 extends into the top groove 12 and abuts against the surface of the side plate 9. A sliding groove 13 is opened on one side of the test box 4. An alcohol friction head 23 is slidably connected in the sliding groove 13. The alcohol friction head 23 abuts against the surface of the sprayed part 22. A moving plate 14 is fixedly connected to the side of the alcohol friction head 23. A limiting plate 15 is fixedly connected to the bottom of the moving plate 14. The limiting plate 15 is slidably connected to the fixed plate 3. A rack 16 is fixedly connected to the side of the limiting plate 15.

[0026] The side plate 9 and clamping plate 20 can be moved by the power of the drive motor 6, thereby limiting the sprayed parts 22 of different lengths. At the same time, the sprayed parts 22 are initially limited by the fastening bolts 21, and the extrusion plate 11 is moved downward by the power of the electric telescopic rod 10, so that the extrusion plate 11 abuts against the side plate 9, thereby preventing the side plate 9 from moving accidentally and improving the abutment and fixing effect on the sprayed parts 22.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, a stepper motor 17 is installed on the top of the base plate 1. A gear 18 is fixedly connected to the output end of the stepper motor 17. The gear 18 is located on the side of the rack 16 and meshes with the rack 16. A through groove 5 is opened on the other side of the test box 4. The through groove 5 is located on the side of the sprayed part 22. A caster 2 is provided at the bottom of the base plate 1. The caster 2 is movably connected to the base plate 1. The clamping plate 20 is U-shaped and made of stainless steel.

[0028] The stepper motor 17 can drive the alcohol friction head 23 to move simultaneously on both sides of the sprayed part 22, thereby enabling simultaneous testing of both sides of the sprayed part 22 and improving the testing range and testing speed of the sprayed part 22.

[0029] The working process of this utility model is as follows: When the alcohol friction mechanism for testing the sprayed coating designed in this scheme is working, according to the length of the sprayed part 22, the switch of the drive motor 6 is turned on, and the drive motor 6 drives the threaded rod 7 to rotate. Since the threaded rod 7 and the threaded sleeve 8 are threadedly connected, the side plate 9 and the clamping plate 20 can be moved, so that both ends of the sprayed part 22 extend into the clamping plate 20. Then the drive motor 6 is turned off, and the fastening bolt 21 is rotated to abut the sprayed part 22. Then the electric telescopic rod 10 drives the extrusion plate 11 to move downward. The extrusion plate 11 can abut the surface of the side plate 9, improving the stability of the side plate 9 and the clamping plate 20. Then the stepper motor 17 drives the gear 18 to rotate. Since the gear 18 and the rack 16 mesh, the limiting plate 15 and the alcohol friction head 23 can move cyclically. The alcohol friction head 23 rubs and tests the two surfaces of the sprayed part 22 simultaneously, improving the testing rate of the sprayed part 22. After the test of the sprayed part 22 is completed, the sprayed part 22 is taken out through the through groove 5.
