[0023] Specific working principle:

[0024] As shown Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, when using the paper pressing wheel for the digital printer, the mounting rod 1 is connected and fixed to the printer through the fixing block 15 and the rotating groove 6. The liquid level gauge 12 can display the horizontal angle of each rubber wheel 10. When adjusting the pressure of the rubber wheel 10 on the paper, the bolt 13 on the upper side of the mounting box 8 can be rotated. The lower end of the bolt 13 rotates on the upper side of the spring 14. When the bolt 13 rotates downward, the compression degree of the spring 14 increases, and the pressure of the rubber wheel 10 on the paper increases. When the bolt 13 rotates upward, the compression degree of the spring 14 decreases, and the pressure of the rubber wheel 10 on the paper decreases. Then, check whether both ends of the rubber wheel 10 are on the same horizontal line through the liquid level gauge 12 and then make adjustments. When it is necessary to disassemble, adjust or replace the rubber wheel 10, rotate the vertical control block 7 to the horizontal. The control block 7 drives the rectangular block 5 to rotate inside the rotating groove 6 through the round rod 4. The rectangular block 5 rotates from the vertical to the horizontal. When the rectangular block 5 rotates to the horizontal, it can move forward through the rotating groove 6 and be taken out, and then the connecting block 3 can be taken out from the inside of the mounting groove 2 to realize the disassembly of the rubber wheel 10. When installing the rubber wheel 10, keep the rectangular block 5 horizontal. After inserting it into the rotating groove 6, rotate the control block 7, and the rectangular block 5 can be limited inside the rotating groove 6. The above completes a series of operations of the paper pressing wheel for the digital printer. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
