[0020] The implementation principle of the rubber roll polishing auxiliary device is that: the electrical elements appearing in the application are externally connected with power supply and control switch during use. During use, the two ends of the rubber roll 8 are placed on the two second arc-shaped plates 11 at the last side respectively. The threaded rod 18 can be rotated by rotating the knob 16, and the first arc-shaped plate 10 can be driven to move downward by the sliding block 17, so that the first arc-shaped plate 10 is tightly attached to the side wall of the rubber roll 8. The above operation can be repeated to install multiple rubber rolls 8 from back to front. The left middle shaft 12 can be rotated by starting the driving motor 6, the connecting disc 3 on the shaft 12 can be rotated, the middle rubber roll 8 can be rotated by the connecting disc 3, and the right middle connecting disc 3 and shaft 12 can be rotated by the rubber roll 8. Therefore, the right rear and right front shafts 12 can be simultaneously rotated by the synchronous wheel 14 and the synchronous belt 15, and multiple rubber rolls 8 can be simultaneously rotated. The polishing plate 5 is driven to move downward by the driving mechanism 9 and is attached to the rubber roll 8, and then the polishing plate 5 is driven to move left and right, so as to polish the surface of the rotating rubber roll 8. When the polishing is completed, the polishing plate 5 is moved to reset by the driving mechanism 9, and then the operation of the driving motor 6 is paused. Due to the randomness of the pause of the driving motor 6, the knob 16 is not necessarily in the position directly above the connecting disc 3. The staff can rotate the right middle shaft 12 by the ratchet 13, so as to rotate the connecting disc 3, adjust the knob 16 to the state of Figure 1 , and then take down the rubber roll 8 and place a new rubber roll 8. In this process, the multiple rubber rolls 8 are placed on the multiple second arc-shaped plates 11 respectively, the first arc-shaped plate 10 is driven to move downward by rotating the threaded rod 18, so as to clamp and fix the rubber roll 8. The multiple rubber rolls 8 are simultaneously rotated by the driving motor 6, so that the polishing plate 5 can polish the multiple rubber rolls 8 at the same time. The need for the operator to hold the polishing tool to polish the surface of the rubber roll 8 is avoided, the uniformity of the subsequent polishing of the rubber roll 8 is ensured, and the working efficiency of the polishing device is improved.

[0021] Referring to Figure 3 , the opposite sides of the first arc-shaped plate 10 and the second arc-shaped plate 11 are fixedly installed with rubber pads 19, which can improve the fixing effect of the first arc-shaped plate 10 and the second arc-shaped plate 11 on the rubber roll 8.
