A fixed shaft 3 is rotatably installed at the slot, and a fixed shaft 3 is provided through the fixed shaft 3. A limiting frame 19 is provided. The limiting frame 19 and the fixing frame 20 are symmetrically provided with a semicircular groove. A bearing sheet 15 is provided through the groove. A roller 17 is provided on the inner wall of the bearing sheet 15. A connecting frame 16 is installed on the outer wall of one side of the limiting frame 19. The connecting frame 16 is provided with multiple groups, which are symmetrically installed on the outer walls of the limiting frame 19 and the fixing frame 20 respectively. The connecting frame 16 is provided with screw holes. A motor bracket 6 is installed on the outer wall of one side of the fixing frame 20. A drive motor 26 is installed through the motor bracket 6. One end of the roller 17 is connected to the drive motor 26. A cleaning component for cleaning the roller 17 is provided on one side of the base 1, and an adjustment component for adjusting the position of the material is provided on one side of the support frame 9;

[0028] When in use, the limiting frame 19 can be controlled to rotate by the rotatable fixed shaft 3, and the limiting frame 19 is lifted by rotation. After being lifted, the roller 17 is placed through the semicircular groove of the fixing frame 20, and the bearing pieces 15 at both ends of the roller 17 are placed in the groove. After the placement is completed, the limiting frame 19 is combined with the fixing frame 20, and the bearing piece 15 is fixed by the circular groove formed by the combination of the limiting frame 19 and the fixing frame 20, and one end of the roller 17 is connected to the driving motor 26. After the limiting frame 19 and the fixing frame 20 are combined, the connecting frame 16 is also completed. After the screw holes are aligned The roller 17 can be fixed by inserting the bolts and tightening the nuts. The fixing frame 20 is driven by the hydraulic telescopic rod 8 to move into the slot of the support frame 9 to complete the adjustment of the position of the roller 17. The two sets of drive motors 26 respectively drive the two sets of rollers 17 to rotate forward and reverse respectively to calender the material. When the roller 17 needs to be replaced, the fixing frame 20 is driven by the hydraulic telescopic rod 8 to move out of the slot of the support frame 9, the bolts and nuts installed on the connecting frame 16 are released, the limit frame 19 is lifted, and the connection between the drive motor 26 and the roller 17 is disconnected to remove the roller 17 for replacement;

[0029] The cleaning assembly includes a mounting frame 13, which is provided with two groups and is symmetrically mounted on the outer wall of the base 1 and the fixed plate 10. A hydraulic lifting rod 12 is fixed to the outer wall of one side of the mounting frame 13 by bolts. The output end of one side of the hydraulic lifting rod 12 can slide through the mounting frame 13. A scraper 14 is detachably mounted at the end of the hydraulic lifting rod 12.

[0030] During use, when the roller 17 has been used for a long time and debris or foreign matter is attached to the surface, the roller 17 is moved out by controlling the hydraulic telescopic rod 8, and the scraper 14 is driven by the hydraulic lifting rod 12 to adjust its height so that it contacts the roller 17. The roller 17 is rotated by controlling the drive motor 26, and the scraper 14 can be used to clean the surface of the roller 17 and scrape off the debris and foreign matter attached to the surface. After use, the scraper 14 can be removed for cleaning, and the scraper 14 can be replaced according to the type of roller 17.
