[0048] Working principle: When in use, the Yunlong paper to be polished is laid flat on the polishing table 12, and then the electric cylinder 3 drives the mounting frame 19 and the pressure roller 42 to move downward, so that the surface of the pressure roller 42 contacts the surface of the Yunlong paper, and then continues to move downward, and the pressure roller 42 is moved laterally linearly in cooperation with the slider 40 and the guide shell 38 by utilizing the rotation of the steering roller 44 and the ability of the pressure roller 42 to rotate, and the Yunlong paper is pre-pressed by the elastic force of the second spring 50, and then the Yunlong paper is positioned and pressed by the pressure block 41 and the steering roller 44. When it is necessary to roughly grind the Yunlong paper, the rack 34 is moved by the electric push rod 31. The rotating member 35 is driven to rotate through the gear ring 33, thereby driving the first lifting sleeve 28 to move downward, so that the rough grinding block 26 moves downward, and at the same time drives the second lifting sleeve 46 to move upward, thereby driving the fine grinding block 27 to move upward, and then the electric telescopic rod 18 drives the grinding assembly to move downward, first the sealing pressure strip 14 contacts the surface of the Yunlong paper, and then the rubber sleeve 13 shrinks and folds and compresses the first spring 21, and at the same time the rough grinding block 26 contacts the Yunlong paper, and then the second motor 24 is used to drive the rough grinding block 26 to rotate to grind the Yunlong paper, and then the driving assembly is used to drive the grinding assembly to move along the trajectory to complete the rough grinding of the Yunlong paper.

[0049] When it is necessary to fine-grind the Yunlong paper, the coarse grinding block 26 is switched to the fine grinding block 27 by using a switching mechanism. The specific operation is that the electric push rod 31 drives the rack 34 to move, and then the ring gear 33 drives the rotating member 35 to rotate in the opposite direction, and then the second lifting sleeve 46 drives the fine grinding block 27 to move downward, and at the same time the first lifting sleeve 28 drives the coarse grinding block 26 to move upward, completing the switching operation of grinding blocks of different roughness, thereby completing the fine grinding of the Yunlong paper.

[0050] During the polishing process of Yunlong paper, the air and dust mixture inside the rubber sleeve 13 is extracted by using the vacuum pump 15, and finally falls into the collection box 16 through the conveying action of the pipeline 52 and the conveying pipe 51, and the dust is filtered by the action of the air filter element, thereby achieving the effect of purifying the air.

[0051] When replacing the air filter element, it is necessary to pull out the drawer in the collection box 16, and then press the rotating shaft 55 downward to make the limiting wheel 59 disengage from the limiting position of the locking block 58, and drive the rotating shaft 55 to rotate by twisting the knob 54, thereby driving the protrusion 65 to rotate synchronously, and then the positioning plate 57 moves under the action of the fourth spring 64, thereby driving the locking pin 56 to contract, thereby achieving the effect of releasing the limiting position of the air filter element, and then the air filter element can be replaced, and then the rotating shaft 55 is pressed downward to move downward so that the limiting wheel 59 is released. The wheel 59 disengages from the limit of the locking block 58, and the rotating shaft 55 is driven to rotate by twisting the knob 54 in the opposite direction, thereby driving the protrusion 65 to rotate synchronously, so that the positioning plate 57 is pushed to drive the locking pin 56 to move, and the locking pin 56 is inserted into the positioning hole in the air filter element to lock the air filter element. Then the rotating shaft 55 is released, so that the resetting effect of the third spring 61 is used to push the rotating shaft 55 to move upward, so that the limiting wheel 59 can limit and position the locking block 58, and thus complete the replacement of the air filter element.
