[0022] An auxiliary part is installed on the side of the workbench 1 near the positioning frame 2, and the auxiliary part includes a mounting seat 5 installed on the upper side of the workbench 1, and a positioning roller 6 is rotatably installed in the mounting seat 5. The rotating installation method includes but is not limited to rotating installation through a rotating shaft or rotating installation through a bearing assembly. A number of mounting grooves are opened on the side of the positioning roller 6, and a ball 7 is rotatably installed in each mounting groove. When the container bag material roll is loaded, the ball 7 arranged on the outside of the positioning roller 6 contacts the container bag material roll. When the container bag material roll is pushed onto the positioning shaft 3, the ball 7 reduces the friction between the container bag material roll and the positioning roller 6, thereby avoiding damage to the container bag fabric in the roll. When the container bag material roll is rotated for loading, the positioning roller 6 supports and positions the container bag material roll. The friction between the container bag material roll and the workbench 1 is reduced by the positioning roller 6 rotating in the mounting seat 5, which facilitates the rotation and loading of the container bag material roll.

[0023] A positioning assembly is installed at one end of the workbench 1, and the positioning assembly includes a fixed frame 8 installed on the side of the workbench 1, a first limiting roller 9 is rotatably installed on the lower part of the side of the fixed frame 8, and a second limiting roller 11 is rotatably installed on the upper part of the side of the fixed frame 8, and a cleaning assembly is provided between the first limiting roller 9 and the second limiting roller 11. The rotation installation method of the first limiting roller 9 and the second limiting roller 11 includes but is not limited to rotation connection through a rotating shaft or rotation connection through a bearing assembly, such as Figure 5 As shown, when the container bag is rotated to load the material, the container bag is located between the first limiting roller 9 and the second limiting roller 11. The container bag fabric is limited by the first limiting roller 9 and the second limiting roller 11, and the cleaning component is used to clean foreign matter on the container bag fabric.

[0024] A guide rod 4 is fixed to the side of the workbench 1, and the positioning frame 2 is slidably set on the guide rod 4. When the positioning frame 2 moves up and down, the guide rod 4 positions and guides it, and a sleeve is fixed to the side of the positioning frame 2 near the guide rod 4, and the sleeve is sleeved on the outside of the guide rod 4. The sleeve is used to increase the contact area between the guide rod 4 and the positioning frame 2, thereby ensuring the stability of the positioning frame 2 when it moves up and down.

[0025] A servo motor 10 is installed on the side of the fixed frame 8. The output shaft of the servo motor 10 is fixedly connected to one end of the first limiting roller 9.
