[0013] Furthermore, the plurality of rectangular liquid outlets are circumferentially arranged in an array along the central axis of the arc-shaped mounting plate.

[0014] The advantages of the present invention are as follows:

[0015] 1. Place the printing paper and the printing backing plate between the driving printing roller and the driven roller. The coating box is filled with printing coating. The coating falls onto the driving printing roller through the middle connecting pipe, the arc-shaped connecting sleeve, and the arc-shaped mounting plate. The printing roller is driven to rotate by the rotating cross bar, and under the extrusion of spring A, the pattern on the printing backing plate falls onto the printing paper to complete printing. At the same time, start the first actuating motor. The first actuating motor drives the driving wheel to rotate. The driving wheel drives the sliding block and the cooperating rotating sleeve to perform a circumferential motion. The circumferential motion of the cooperating rotating sleeve drives the driving bracket to slide reciprocally, causing the middle connecting pipe to slide reciprocally along the chute, and causing the arc-shaped connecting sleeve to slide reciprocally on the printing roller, realizing the replenishment of the coating on the printing roller. At the same time, as the adjusting screw rotates, the sliding block slides along the driving wheel, changing the circumferential motion of the sliding block, changing the reciprocating sliding stroke of the middle connecting pipe in the chute, and changing the reciprocating sliding stroke of the arc-shaped connecting sleeve on the printing roller to adapt to printing paper of different widths, avoiding excessive coating feeding, and realizing the saving of coating.

[0016] 2. Start the second actuating motor. The second actuating motor drives the second driving disc to rotate. The second driving disc drives the sliding bracket to slide reciprocally along the rectangular sliding frame through the cooperating column A. Driven by the rectangular sliding frame, the magnetic slider slides reciprocally in the arc-shaped sliding frame, and driven by the magnetism of the magnetic slider, the middle partition plate slides in the connecting sleeve. Since the connecting sleeve is a semi-arc-shaped structure, to prevent the coating in the connecting sleeve from precipitating, as the middle partition plate slides reciprocally in the connecting sleeve along with the magnetic slider, the coating in the connecting sleeve is stirred up under the reciprocating motion of the middle partition plate, avoiding the precipitation of the coating in the connecting sleeve.
