A symmetrical polishing and grinding shaft 2 is provided inside the support base 14, and the two ends of the central axis of the polishing and grinding shaft 2 are respectively rotatably connected to the two sides of the cavity shell 1. The support base 14 is respectively rotatably connected to the two ends of the rotating shaft 18. There are at least two rotating shafts 18. The rotating shafts 18 are connected by a conveyor belt 15, and the conveyor belt 15 is in contact with the surface of the polishing and grinding shaft 2.

[0024] It also includes a driving assembly, which is used to drive the polishing and grinding shaft 2 and the rotating shaft 18 to rotate.

[0025] In this embodiment, the rotation of the rotating shaft 18 can drive the conveyor belt 15 to move, and the rotation of the polishing and grinding shaft 2 can polish and squeeze the upper side of the paper. The rotating shaft 18 drives the paper on the conveyor belt 15 to move and polish and squeeze the lower side of the paper. The paper is between the polishing and grinding shaft 2 and the conveyor belt 15 and contacts the surface of the polishing and grinding shaft 2 and the surface of the conveyor belt 15 on both sides respectively. Under the rotation of the polishing and grinding shaft 2 and the conveyor belt 5, the paper is clamped and moved between the two to achieve extrusion polishing on both sides of the paper. The polishing and grinding shaft 2 and the conveyor belt 5 drive the paper to move and send it out from the other end of the cavity shell 1.

[0026] The driving assembly includes a rotating wheel 8, and one end of the central axis of each polishing and grinding shaft 2 is fixedly connected to the center of the rotating wheel 8. The rotating wheel 8 is rotatably connected to the rotating wheel connecting frame 3, and the rotating wheel connecting frame 3 is fixedly connected to the support frame 4. The rotating wheel 8 is connected through a belt 9. The center of one of the rotating wheels 8 is connected to the output end of the reducer 5, and the input end of the reducer 5 is fixed with the output shaft of the motor 6, and the motor 6 is fixed to the base 7.

[0028] In this embodiment, the motor 6 drives the wheel 8 to rotate through the reducer 5, the wheel 8 drives another wheel 8 to rotate through the belt 9, the two wheels 8 drive the polishing and grinding shaft 2 to rotate, and the polishing and grinding shaft 2 drives the driving wheel 10 to rotate, the driving wheel 10 drives the round wheel 12 to rotate through the second belt 11, and the round wheel 12 drives the rotating shaft 18 and the conveyor belt 15 to rotate through the connecting shaft 13, so that the polishing and grinding shaft 2 and the conveyor belt 5 rotate to perform surface calendering of the paper and transport the paper at the same time.

[0032] When in use, start the motor and place the paper to be calendered between the polishing grinding shaft 2 and the conveyor belt 15, ensuring that the paper is placed flat and free of wrinkles or foreign matter. The conveyor belt 15 and the polishing grinding shaft 2 start to rotate, and the paper begins to be clamped and moved. The status of the paper is monitored by the visual sensor to ensure that the paper is not stuck or other abnormalities during the calendering process. If the visual sensor detects an abnormality, the controller will automatically stop the motor and issue an alarm signal, waiting for the paper to completely pass through the polishing grinding shaft 2 and the conveyor belt 15, and take out the calendered paper from the other end of the cavity shell 1.
