This design is to allow the raw material to slide through the brush block 20, driving the brush block 20 to expand outward, thereby driving the connecting block 19 and the round rod 17 to slide on the inner wall of the protective block 15. The function of the brush block 20 is to sweep away dust on the outside of the raw material.

[0029] refer to Figure 4 , a support plate three 21 is fixedly connected to the top right side of the right end support column 2, the support column 2 supports the support plate three 21, and a water tank 22 is fixedly connected to the top of the support plate three 21. Water is stored in the water tank 22, and a water pump 23 is fixedly connected to the top of the water tank 22. The water pump 23 is started to extract water from the water tank 22, and a connecting pipe 24 is fixedly connected to the output end of the water pump 23. A fixed block 25 is fixedly connected to the middle part of the rear side of the support column 2, and a spraying pipe 26 is fixedly connected to the rear end of the connecting pipe 24. The water in the water tank 22 is extracted by the water tank 22 and flows into the spraying pipe 26 through the connecting pipe 24 and then sprayed onto the surface of the raw material from the holes of the spraying pipe 26 to perform humidification. The left side of the connecting pipe 24 and the water tank 22 are fixedly connected to the middle part of the right side of the right support column 2, and the rear side of the fixed block 25 is fixedly connected to the left and right ends of the front side of the spraying pipe 26, and the fixed block 25 supports the spraying pipe 26.

[0030] Working principle: First, the user squeezes the paper from the inside of the brush block 20 and drives the connecting block 19 and the spring 18 to move inside the ring 16. Under the elastic force of the round rod 17, the brush block 20 is indirectly driven to close to the surface of the paper to sweep away the dust and particles on the surface of the paper. Then the motor group 9 and the water pump 23 can be started. The water pump 23 draws the connecting pipe 24 in the water tank 22 into the spray pipe 26 to spray water on the paper. When the paper passes between the top roller 10 and the bottom roller 5, the heat energy of the pressing roller quickly enters the inside of the paper, realizing the rapid transfer of heat, and further improving the calendering effect of the paper. The motor group 9 drives the top roller 10 to rotate, and presses the paper raw material moved to the middle of the top roller 10 and the bottom roller 5 to make the paper thinner. When the user needs to lift the top roller 10 for maintenance and repair, the compression cylinder 7 can be started to pull the slider 8 to drive the top roller 10 to slide synchronously in the slide groove 11, so that the top roller 10 can be lifted. While the slider 8 slides, the gear 12 defined inside the rear side of the slider 8 will synchronously rotate and slide on the rack 13 and engage with the external teeth of the rack 13 to prevent the slider 8 and the top roller 10 from shaking unsteadily during the lifting process.
