Description

Technical Field

[0001] The utility model relates to the technical field of folding devices, in particular to a folding device for packaging materials for packaging bags. Background Technique

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation and storage of goods during the production and circulation processes. It is widely used in daily life and industrial production. Actual figures show that 80% of the plastic bags after use are ultimately transported to landfill sites for disposal like general garbage, and only 7% of the plastics are recycled. It mainly includes sealing or hot pressing operations, where the sides of the folded film or other packaging materials are sewn or hot press-sewn to form a seal. Currently, most of the devices for folding packaging materials are manually adjusted by personnel, which cannot automatically detect and adjust according to the requirements of packaging bag processing, resulting in subsequent folding being affected. For this reason, we propose a folding device for packaging materials for packaging bags. Content of the Utility Model

An arc support frame can be used to support the packaging materials. The motor drives the screw rod to rotate to adjust the position of the positioning plate. Starting the electric push rod can make the pressing plate bend the packaging materials. Subsequently, the hydraulic rod drives the pressing roller to press down to fold the bent packaging materials, facilitating subsequent heat sealing processing, and effectively solving the problems in the background technique.
