Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a cutting device for plastic bag production which can prevent material deviation. Background Art

[0002] The cutting device used in plastic bag production is a key mechanical component used to cut continuous plastic film into individual plastic bags according to specific sizes. This device usually includes components such as blades, guide rollers, tension control system, and cutting control system. The blades are responsible for physically cutting the plastic film, the guide rollers ensure that the film passes smoothly through the cutting area, the tension control system maintains constant film tension to ensure cutting quality, and the cutting control system controls the movement of the blades to achieve precise cutting.

[0003] Conventional cutting devices for plastic bag production may cause the plastic bags to deviate during the cutting process due to different forces applied to the plastic bags. This results in poor appearance of the cut plastic bags. The deviation also degrades the performance of the plastic bags themselves, making them more susceptible to breakage after being subjected to force. This makes the performance of the plastic bags fail to meet the requirements for use and easily creates risks in use.

A cutting device for plastic bag production that can prevent material shifting can be designed. The device can fix the plastic bag during the cutting process, thereby preventing the plastic bag from shifting, ensuring that the performance of the plastic bag meets the usage indicators, and reducing the use risks caused by the use of the plastic bag.
