[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. In the production process of plastic bags, a slitting device is required to cut the plastic bags into appropriate sizes.

[0003] According to the description of a plastic bag production and slitting device disclosed on the patent website (authorization announcement number: CN 220615094 U), "the utility model discloses a plastic bag production and slitting device, including a fixed frame, a slitting lifting mechanism, a pressure roller adjustment mechanism and a disassembly mechanism; the fixed frame: there are two of them, and the left and right sides between the two fixed frames are rotatably connected with conveying rollers, and the two conveying rollers are connected through a conveyor belt transmission. A second motor is arranged on the left side of the front fixed frame, and the rear end of the output shaft of the second motor is fixedly connected to the front end of the conveying roller on the left side. A left-right symmetrical base is arranged between the bottoms of the two fixed frames; the slitting lifting mechanism: it is arranged at the upper right end of the discharge chute; the pressure roller adjustment mechanism: it is arranged at the upper left end between the two fixed frames. The plastic bag production and slitting device can disassemble or replace the rotating roller more conveniently and quickly, and personnel can quickly replace the rolled plastic bags that need to be slid according to needs. The up and down movement of the slitting mechanism greatly reduces the slitting time and improves the slitting efficiency."
