The two ends of the plate roller are placed on the top of the two fixed blocks 4 on the same side, and then the locking assembly 6 on the same side is controlled to unlock the fastening assembly 5, and then the fastening assembly 5 is moved to the top of the fixed block 4 on the same side, and then the ends of the plate roller are fixed to the top of the fixed blocks 4 on both sides by controlling the fastening assembly 5, so as to fix the plate rollers of different sizes and improve the stability of the plate roller fixation. After the plate roller is fixed, the driving assembly 3 is started to drive the mounting frame 2 to be retracted into the middle of the fixing frame 1, so as to reduce the space occupied by the equipment and reduce the storage cost of the plate roller.

[0021] Specifically, the fixing frame 1 is U-shaped, and a plurality of guide grooves 7 for the movement of the mounting frame 2 are provided on the inner wall of the fixing frame 1 .

[0022] like Figure 2 and Figure 4 As shown, specifically, the side wall of the mounting frame 2 is symmetrically provided with a slide bar 21, the top of the mounting frame 2 is provided with a connecting plate 22 facing outward, the top of the mounting frame 2 is symmetrically provided with a slide groove 23 about the fixed block 4, the inner wall of the slide groove 23 is symmetrically provided with a plug hole 24, the side of the mounting frame 2 is connected to the slide groove 23 through the plug hole 24 and is provided with a locking cavity 25, which moves along the guide groove 7 through the slide bar 21, thereby improving the stability of the mounting frame 2 during the outward movement.

[0023] Specifically, the driving assembly 3 includes an electric cylinder 31 with a telescopic end fixedly connected to the connecting plate 22 on the inner wall of the fixing frame 1. By controlling the telescopic end of the electric cylinder 31, the mounting frame 2 in the middle of the fixing frame 1 is driven to extend from both sides of the fixing frame 1, so as to facilitate the fixing of the plate roller.

[0024] Specifically, the fastening assembly 5 includes a U-shaped frame 51 slidably provided in the slide groove 23, a lock hole 52 is provided on the side wall of the U-shaped frame 51 corresponding to the plug-in hole 24, a threaded hole 53 is provided on the top of the U-shaped frame 51, a push rod 54 is threadedly connected in the threaded hole 53, a handle 55 is fixed on the top of the push rod 54, and a fixed block 2 56 is rotatably connected at the bottom of the push rod 54.
