DETAILED DESCRIPTION

[0017] See also Figures 1 to 4The scraper for a screen printing machine shown in the figure comprises a scraper body 11, a scraper blade 12 is provided at the bottom of the scraper body 11, a mounting plate 14 and a mounting plate 2 15 are provided on the left and right sides of the scraper body 11, the mounting plate 14 is connected to the mounting plate 2 15, a threaded rod 16 is provided on the front and rear sides of the scraper body 11, the threaded rod 16 is rotatably arranged between the two mounting plates 2 15, a cleaning assembly 13 is provided between the two threaded rods 16, and the cleaning assembly 13 comprises a U-shaped mounting seat 18, and the U-shaped mounting seat 18 is arranged on one side of the scraper body 11. On the side, U-shaped connecting seats 22 are provided on the upper sides of the two side walls of the U-shaped mounting seat 18, and the U-shaped connecting seats 22 are connected to the threaded rod 16. An electric-controlled telescopic rod 23 is connected between the two U-shaped connecting seats 22 and the U-shaped mounting seat 18. A sliding rod 19 is provided at the bottom of the U-shaped mounting seat 18, and two wiping components 20 are provided on the sliding rod 19; when the scraper blade 12 is used to scrape ink, the cleaning component 13 is docked on one side of the scraper body 11, and the bottom position of the U-shaped mounting seat 18 is higher than the bottom position of the scraper blade 12, so that the cleaning component 13 will not hinder the movement of the scraper blade 12.

[0018] Furthermore, the wiping assembly 20 includes a cleaning block 24 and a cleaning sponge 26. The cleaning block 24 is slidably set on the slide rod 19. A spring is connected between the cleaning block 24 and the inner wall of the U-shaped mounting seat 18. The cleaning sponge 26 is in a U-shaped structure. The cleaning block 24 is provided with a slot corresponding to the cleaning sponge 26. One side wall of the cleaning sponge 26 is plugged into the slot on the cleaning block 24. When the cleaning sponge 26 needs to be replaced, the cleaning sponge 26 is directly taken out of the slot on the cleaning block 24 and a new cleaning sponge 26 is inserted. The replacement is simple and convenient.

[0019] Furthermore, a magnet sheet 25 is provided on one side surface of the cleaning block 24, and an electromagnet 21 corresponding to the magnet sheet 25 is provided on the inner wall of the U-shaped mounting seat 18; when the electromagnet 21 is started, the electromagnet 21 can repel the magnet sheet 25 by magnetic force, so that the cleaning block 24 moves along the slide rod 19, so that the two cleaning sponges 26 approach each other and clamp the scraper blade 12, and when the electromagnet 21 is turned off, the cleaning block 24 is reset under the action of the spring, and the two cleaning sponges 26 can release the scraper blade 12.

[0020] Furthermore, a connection groove 27 is provided on one side of the second mounting plate 15 , and the scraper body 11 is plugged into the connection groove 27 , and bolts are provided between the second mounting plate 15 and the scraper body 11 .

[0021] Furthermore, two motors 17 are provided on the mounting plate 2 15 on one side of the scraper body 11, and the output shafts of the two motors 17 are respectively connected to the two threaded rods 16; starting the motor 17 to rotate the threaded rod 16 can control the U-shaped connecting seat 22 to move along the threaded rod 16, thereby causing the U-shaped mounting seat 18 to move accordingly.

[0022] The working principle of the utility model is that after the screen printing is completed, the electric-controlled telescopic rod 23 is started to extend so that the U-shaped mounting seat 18 moves down a certain distance. At this time, the bottom of the scraper blade 12 is located on the upper side of the sliding rod 19, and the main body of the scraper blade 12 is located between the two wiping components 20. At this time, the motor 17 is started to rotate the threaded rod 16, so that the U-shaped connecting seat 22 moves along the threaded rod 16, and the U-shaped mounting seat 18 moves accordingly. When the U-shaped mounting seat 18 moves to the bottom of one end of the scraper blade 12, the motor 17 is turned off, and then the electromagnet 21 is started. The electromagnet 21 repels the magnet sheet 25 through magnetic force, so that the two cleaning blocks 24 are close to each other, so that the two cleaning sponges 26 clamp the scraper blade 12, and then the motor 17 is started again to move the U-shaped mounting seat 18, so that the two cleaning sponges 26 are translated along the scraper blade 12, so that the cleaning sponge 26 is used to clean the ink remaining on the surface of the scraper blade 12.

[0023] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
