Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a bracket for packaging bag production. Background Art

[0002] Packaging bags refer to bags used to pack various items and are widely used in daily life and industrial production. Woven bags are a type of packaging bags. In order to improve the waterproofness, durability and sealing of woven bags, a plastic film bag is usually placed on the woven bags before sewing.

[0003] For example, in the prior art, a Chinese patent with the authorization announcement number CN218804363U discloses a support for producing packaging bags, which is provided with a double-headed motor, a threaded rod, a movable plate, a threaded hole, a vertical plate and a fixed clamp. The double-headed motor can drive the threaded rod to rotate inside the threaded hole, and the movable plate can move on the threaded rod. At the same time, the two vertical plates will move away from each other, and the fixed clamp will drive the packaging bag to move. The packaging bag will be flattened to prevent the packaging bag from wrinkling, which is beneficial for the staff to sew the film bag;

[0004] Although the device can facilitate the straightening of the packaging bag, during the operation, the staff needs to manually clamp the packaging bag on the fixing clamp and then straighten it, which is not only inconvenient to operate, but also the packaging bag is easy to fall off from the fixing clamp during the straightening process. After the packaging bag is straightened, the opening of the packaging bag is in a closed state, which is not convenient for sewing the plastic film bag of the packaging bag. Therefore, a bracket for packaging bag production is designed to solve the above problems. Utility Model Content
