The upper and lower sides of the roller 15 are respectively provided with There are multiple groups of matching sockets 17 for inserting rods 16. When replacing the roller 15, the nut 13 drives the rotating ring 2 14 to be removed from the mounting shaft 10, the roller 15 is removed, and the new roller 15 is sleeved on the outside of the mounting shaft 10, and the multiple groups of plug rods 16 on the upper side of the rotating ring 12 are inserted into the sockets 17 on the lower side of the roller 15, and the nut 13 is threadedly sleeved on the upper part of the mounting shaft 10. When the nut 13 moves downward, the plug rod 16 on the lower side of the rotating ring 2 14 is inserted into the socket 17 on the upper side of the roller 15, and the nut 13 is tightened to stably install the roller 15 to complete the replacement of the roller 15.
[0024] The left side wall of the positioning plate 18 is hinged to the upper side of the left group of support plates 2, and the right side wall of the positioning plate 18 is connected to a U-shaped frame 20. The front and rear side walls of the U-shaped frame 20 are respectively located on the front and rear sides of the right group of support plates 2 and are matched and connected with bolts 21. The positioning plate 18 is provided with a through hole 19 for the installation shaft 10 to pass through. The front and rear sides of the installation shaft 10 are respectively in contact with the front and rear side walls of the through hole 19. The positioning plate 18 is rotated to the outer side of the upper part of the installation shaft 10, and the U-shaped frame 20 is connected to the right group of support plates 2 by bolts 21.
