Description

Technical Field

[0001] This utility model relates to the field of ink testing technology, and in particular to an ink decolorization tester. Background Technology

[0002] Ink decolorization tester is a testing instrument mainly used for testing the abrasion resistance of printed ink layers, PS plate photosensitive layers, and related product surface coatings.

[0003] In existing technologies, graphite decolorization testing machines typically fix the ink plate to be tested directly on the surface of the testing machine, and then move the ink plate with the paint film on the surface through a friction head. The wear resistance of the paint film is verified by changing the friction between the sandpaper and the paint film.

[0004] However, the existing technology cannot adjust the height of the ink plate. When the ink plate is very thin, the surface of the friction head cannot adhere well to the ink plate. When personnel conduct decolorization tests on two ink plates of different thicknesses for comparison, they cannot obtain good results. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an ink decolorization test machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An ink decolorization testing machine includes a platform, a machine body, a friction head, a placement seat, a clamping device, and a power unit. The placement seat is used to place the ink plate to be tested and can clamp the ink plate by the clamping device. The power unit is located on the machine body and is used to drive the friction head to move back and forth on the placement seat. A groove is provided on the machine body, and an adjustment device is also provided on the placement seat. The placement seat is movably disposed in the groove, and the vertical position of the placement seat can be adjusted by the adjustment device.

[0008] As described above, in an ink decolorization tester, the adjusting device includes screws located at the left and right ends of the placement seat, and vertical adjusting grooves connected to the grooves are provided on both the left and right sides of the machine base. The screws pass through the vertical adjusting grooves and are threaded with locking nuts at their outer ends.

[0009] As described above, in an ink decolorization testing machine, an anti-slip pad is also fitted onto the screw, and the anti-slip pad is abutted against the side wall of the machine base by a locking nut.

[0010] As described above, in an ink decolorization tester, a first guide post is spaced at the lower end of the placement seat, and a guide hole that mates with the first guide post is provided on the bottom wall of the groove.

[0011] As described above, in an ink decolorization tester, the clamping device includes an arched frame spaced between the left and right ends of the placement seat, a pressure plate that moves up and down inside the arched frame, and a bolt threadedly connected to the upper end of the arched frame, the lower end of the bolt being able to push against the pressure plate.

[0012] As described above, in an ink decolorization testing machine, there are second guide columns spaced apart on the pressure plate, and the second guide columns are movably inserted through the arched frame.

[0013] As described above, an ink decolorization tester has a spring sleeved on the second guide column, with the upper end of the spring abutting against the arched frame and the lower end abutting against the pressure plate.

[0014] The beneficial effects of this utility model are as follows: by setting a groove on the machine base and setting an adjustment device on the placement seat, the placement seat is movably positioned in the groove and the vertical position of the placement seat can be adjusted by the adjustment device; that is to say, ink plates of different thicknesses on the placement seat can all be pressed against the friction head, so that when the friction head squeezes ink plates of different thicknesses, the pressure on the ink plates is roughly the same, which increases the accuracy of the conclusions of the comparative test to a certain extent.

[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 and Figure 4As shown, an ink decolorization testing machine includes a platform 1, a machine body 2, a friction head 3, a placement seat 4, a clamping device, and a power unit. The placement seat 4 is used to place the ink plate to be tested and can clamp the ink plate by the clamping device. The power unit is located on the machine body 2 and is used to drive the friction head 3 to move back and forth on the placement seat 4. A groove 5 is provided on the platform 1, and an adjustment device is also provided on the placement seat 4. The placement seat 4 is movably disposed in the groove 5, and the vertical position of the placement seat 4 can be adjusted by the adjustment device.

[0022] Based on the above structure, ink plates of different thicknesses on the placement seat 4 can all abut against the friction head 3, so that when the friction head 3 squeezes ink plates of different thicknesses, the pressure on the ink plates is roughly the same, which increases the accuracy of the comparative test conclusions to a certain extent.

[0023] See Figure 3 , Figure 4 As shown, the adjustment device includes screws 21 located at the left and right ends of the placement seat 4. Vertical adjustment grooves 22 connected to the grooves 5 are provided on both the left and right sides of the machine base 1. The screws 21 pass through the vertical adjustment grooves 22 and are threaded with locking nuts 23 at their outer ends.

[0024] When adjusting the vertical position of the placement seat 4, the screw 21 moves up and down within the vertical adjustment groove 22. When the position is adjusted to a suitable level, the locking nut 23 can be tightened directly. The structure is simple and the operation is convenient.

[0025] To improve the stability of the mounting base 4 after it is fixed, an anti-slip pad 30 is also fitted on the screw 21. The anti-slip pad 30 is abutted against the side wall of the machine base 1 by the locking nut 23.

[0026] See Figure 3 As shown, a first guide post 31 is spaced at the lower end of the placement seat 4, and a guide hole 32 that cooperates with the first guide post 31 is provided on the bottom wall of the groove 5; thereby enabling the placement seat 4 to move up and down stably.

[0027] See Figure 1 , Figure 4 As shown, the clamping device includes an arched frame 41 spaced between the left and right ends of the placement seat 4. A pressure plate 42 moves up and down inside the arched frame 41. A bolt 43 is threadedly connected to the upper end of the arched frame 41. The lower end of the bolt 43 can push against the pressure plate 42.

[0028] Furthermore, a second guide post 51 is spaced apart on the pressure plate 42, and the second guide post 51 is movably inserted through the arched frame 41.

[0029] Furthermore, a spring 61 is fitted onto the second guide post 51, with the upper end of the spring 61 abutting against the arched frame 41 and the lower end abutting against the pressure plate 42.

[0030] When clamping the ink plate, the ink plate is first pressed by the action of the spring 61. After the pressing operation, the pressure plate 42 is pressed tightly by rotating the bolt 43, thereby firmly clamping and fixing the ink plate.
