[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Please refer to Figures 1 to 2 , in the embodiment of the present invention, an auxiliary pressure roller for a slitter includes a slitter support 1. After the bag body 4 is slit by the slitter, it is conveyed downward to the next station through the conveyor roller 11 on the slitter support 1. A mounting seat 12 fixed by bolts and other structures is fixed on the slitter support 1, and the mounting seat 12 and the slitter support 1 form a detachable fit.

[0026] A positioning pin 121 is provided on the mounting seat 12, and the axis of the positioning pin 121 is arranged parallel to the axis of the conveyor roller 11. The mounting bracket 2 is hung on the positioning pin 121 of the mounting seat 12 and can thus rotate around the positioning pin 121. The mounting bracket 2 is preferably arranged in an L shape, and a guide groove 21 is opened along the vertical direction at one end, and the opening of the guide groove 21 faces downward. The diameter of the positioning pin 121 corresponds to the groove width of the guide groove 21. The positioning pin 121 is inserted into the guide groove 21 and abuts against the groove bottom surface of the guide groove 21. The other end of the mounting bracket 2 is coaxially fixed with the roller shaft of the auxiliary pressure roller 3, and the roller shaft of the auxiliary pressure roller 3 is arranged parallel to the axis of the conveyor roller 11.

[0027] Under the action of gravity, the auxiliary pressure roller 3 naturally presses down on the conveyor roller 11, thereby applying a pressing force to the bag body 4. To further improve the pressing effect, a hook spring 22 is also provided on the mounting bracket 2. One end of the hook spring 22 is hung on the mounting seat 12, and the other end of the hook spring 22 is hung on the roller shaft of the auxiliary pressure roller 3. The hook spring 22 is always in a stretched state, thereby applying an elastic pressing force to the auxiliary pressure roller 3 to press it against the conveyor roller 11. Through the pressing of the auxiliary pressure roller 3, the phenomenon of the slit part of the bag body 4 warping is avoided.

[0028] Rollers 31 are evenly arranged on the roller shaft of the auxiliary roller 3 along the length direction, and the rollers 31 correspond to the cutting position of the bag body. In order to facilitate the movement of the rollers 31 to adapt to different products, a slide groove 32 is opened on the roller shaft of the auxiliary roller 3 along the length direction, and each roller 31 slides with the slide groove 32, so that the position of the roller 31 is easy to adjust. After the roller 31 slides to the set position, it can be locked by a pin. In order to further prevent the bag body 4 from warping, a resistive heating device is embedded in each roller 31, which heats and shapes the bag body while applying pressure to it, so that the cutting position of the bag body is smoother.
