[0029] The working principle of the high-efficiency rotary screen printing machine provided by the utility model is as follows:

[0030] When in use, the substrate is placed on the placement table 6, and the oil pump 12 draws ink from the ink box 11 and delivers it to the printing plate 14 through the soft oil pipe 13. When the printing plate 14 is full of ink, the oil pump 12 stops delivering ink. At this time, the electric telescopic rod 25 is started, and the electric telescopic rod 25 retracts to drive the U-shaped mounting plate 9 to descend, and the U-shaped mounting plate 9 drives the mounting frame 17 to descend. When the screen printing screen 26 presses the substrate, the electric telescopic rod 25 stops falling.

[0031] The electric telescopic rod 16 is started, and the output rod of the electric telescopic rod 16 is extended to drive the printing plate 14 to move to the right, and the printing plate 14 prints the pattern on the screen 26 onto the substrate. When the printing plate 14 moves to the right and contacts the slider 18, the printing plate 14 and the slider 18 slide together and push the slider 18 to move to the inside of the limit groove of the L-shaped sliding rod 20, while compressing the spring 19. When the printing plate 14 is separated from the slider 18, the slider 18 extends to the outside of the L-shaped sliding rod 20 under the reset force of the spring 19, so that when the printing plate 14 moves to the left, it drives the slider 18 to slide along the avoidance groove.

[0032] After printing is completed, the electric telescopic rod 25 is extended to drive the mounting frame 17 to move upward through the U-shaped mounting plate 9, and the mounting frame 17 drives the screen 26 to separate from the substrate.

[0033] At this time, the output rod of the electric telescopic rod 16 contracts and drives the printing plate 14 to move to the left. At the same time, the printing plate 14 drives the L-shaped sliding rod 20 to move to the left by pushing the slider 18. At the same time, the L-shaped sliding rod 20 slides to the left on the fixed shaft 21, making the L-shaped sliding rod 20 more stable when sliding. When the L-shaped sliding rod 20 moves to the left, the spring 22 is stretched. The L-shaped sliding rod 20 drives the scraper box 23 to move to the left at the same time. The scraper plate of the scraper box 23 cleans the ink at the bottom of the screen 26, and the scraped ink flows along the scraper plate to the collection box of the scraper box 23.

[0034] When the printing plate 14 drives the L-shaped sliding rod 20 to move to the left side of the mounting frame 17, the slider 18 and the inclined wedge surface 24 slide together, so that the slider 18 retracts into the limit groove of the L-shaped sliding rod 20 again and compresses the spring 19. When the slider 18 and the printing plate 14 are out of contact, the L-shaped sliding rod 20 and the oil scraper box 23 are pulled to reset under the reset force of the spring 22.

[0035] Start the motor 2, the motor 2 drives the gear 3 to rotate, the gear 3 drives the gear ring 4 to rotate, the gear ring 4 drives the turntable 5 to rotate, thereby driving the next placement table 6 to rotate to the bottom of the screen printing screen 26, and start printing the next substrate.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
