Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, and in particular to an adjustment device for plastic bag production. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, and nylon). They are essential items in daily life and are often used to store other items. Due to their low cost, extremely light weight, large capacity, and ease of storage, they are widely used. However, plastic bags tend to stick to the cutting blade during cutting, leading to errors and even affecting subsequent cutting operations, causing significant production problems. Therefore, we propose a cutting device for LDPE plastic bags.

[0003] For example, the utility model patent with authorization announcement number CN209176231U discloses a cutting device for LDPE plastic bags, which includes a base. Two symmetrically arranged support columns are fixedly installed on the top of the base. The top of the two support columns is fixedly installed with the same top plate. Two pneumatic push rods are fixedly installed on the top of the top plate. The same knife holder is fixedly installed on the output shaft of the two pneumatic push rods. The knife holder is located at the bottom of the top plate. A blade is fixedly installed at the bottom of the knife holder. Fixed seats are fixedly installed on both sides of the knife holder. The bottom of the two fixed seats is provided with a compression spring groove. A slide rod is slidably installed in the two compression spring grooves. A compression spring is fixedly installed at the top of the two slide rods. However, the cutting device can only be adjusted in one way and cannot adjust the cutting position according to the needs. In view of this, an adjustment device for plastic bag production is proposed. Utility Model Content
