[0020] In this embodiment, as Figure 1-2 As shown, the mounting bracket 1 is connected to the printing press. During assembly, the coupling 4 is connected to the first drive module 3 and the doctor blade module 2 via the fixed base 5, so that when the second drive module 6 is working, it drives the first drive module 3 and the doctor blade module 2 to rotate via the coupling 4, thereby adjusting the angle of the doctor blade module 2.

When it is necessary to perform circumferential scraping operations on the surface of the printed material, the first drive module 3 is turned off and the second drive module 6 is activated, which drives the coupling 4 to rotate, thereby driving the doctor blade module 2 to perform circumferential scraping operations. The overall structure is stable and easy to install.

[0021] Furthermore, the scraper module 2 includes: a blade 21, a mounting base 22, and a support rod 23; the blade 21 is fixedly mounted on the bottom of the mounting base 22; the support rod 23 is slidably mounted on the fixed base 5, and its two ends are respectively fixedly connected to the mounting base 22; a transmission gear 24 is provided on the support rod 23; a mounting cavity is provided on the fixed base 5; the transmission gear 24 is placed in the mounting cavity and is connected to the output end of the first drive module 3.

[0022] In this embodiment, as Figure 2 As shown, the fixed base 5 is provided with a sliding groove 10 that matches the support rod 23, so that the support rod 23 can slide back and forth on the fixed base 5. During operation, the output end of the first drive module 3 is connected to the transmission gear 24, which drives the support rod 23 to move back and forth along the sliding groove 10 on the fixed base 5, so that the blade 21 can perform back and forth scraping operation.

[0026] In this embodiment, as Figure 2 As shown, the second drive motor 61 is a servo motor. The second drive motor 61 drives the first transmission pulley 64 to rotate through the second reducer 63. During the rotation of the first transmission pulley 64, the second transmission pulley 65 is driven to rotate through the transmission belt 66, which in turn drives the connecting shaft 4 to rotate. During the rotation of the connecting shaft 4, the fixed base 5 is driven to rotate, thereby driving the scraper module 2 and the first drive module 3 connected and installed on the fixed base 5 to rotate, so as to realize the scraping angle adjustment operation of the blade 21 of the scraper module 2.
