The rotating shaft 23 is rotatably connected to the L-shaped plate 22 through a bearing. The servo motor 24 is fixedly installed on the side of the L-shaped plate 22, and the output shaft of the servo motor 24 is fixedly connected to the rotating shaft 23. One end of the rotating shaft 23 is fixedly installed on the first roller 25 through a chuck.

The second cylinder 31 is fixedly installed on one side of the second support plate 30. The piston rod of the second cylinder 31 is fixedly installed on the U-shaped plate 32. The end of the second roller 33 is rotatably connected to the U-shaped plate 32 through a bearing. The upper and lower ends of the middle side of the L-shaped bracket 10 are rotatably connected to the third roller 34 through a bearing.

[0048] It also includes: a moving component for ensuring the stability of the L-shaped bracket 10 while facilitating the movement of the L-shaped bracket 10, and the moving component is disposed on the L-shaped bracket 10;

[0049] The moving components include: casters 40, a third cylinder 41, a square plate 42, a flow channel 43, a vacuum suction cup 44, a vacuum pump 45, and a pipe 46;

[0050] Several casters 40 are fixedly installed at the bottom of the L-shaped bracket 10. A third cylinder 41 is fixedly installed at the top of the L-shaped bracket 10 located on one side of the casters 40.
