Description

TECHNICAL FIELD

[0001] The utility model relates to packing and packaging operation equipment technical field, concretely is hot sealing drive assembly for packing equipment. BACKGROUND

[0002] The packaging bag is usually sealed by hot pressing the end of the whole roll of film during production and processing. The existing sealing machine sets a heating strip on the pressing block, then hot-press seals the packaging bag, and then cuts it to process into a packaging bag with one end sealed.

[0003] For example, the patent with the announcement number CN117699152A and the Chinese authorized patent name (a packaging bag hot sealing assembly) includes a mounting plate and two sets of hot-pressing clamps mounted on one side of the mounting plate. The outer surface of the mounting plate is provided with a lifting arm, and the lifting arm is provided with a clamp and a driving mechanism. The clamp and the driving mechanism are arranged on the other side of the mounting plate. The packaging bag hot sealing assembly starts the clamping drive cylinder to drive the rotating shaft to rotate, and the two sets of hot-pressing clamps are driven by the two sets of connecting rods to realize the opening and closing action. The opening and closing distance is ensured by the speed reducer during the whole process to achieve the purpose of precise control. The rotating shaft is driven by the clamping drive cylinder, and the whole process is continuous without changing direction. It can continuously work in the same direction. Compared with the cylinder that needs to be pushed back and forth, it is more efficient, has no noise, has fast overall response speed, high transmission efficiency, and can realize the production speed of the whole clamping block by adjusting the transmission speed of the plastic film.

[0004] However, the existing hot sealing drive assembly needs to be highly matched between the connecting rods during bidirectional movement when in use, resulting in high damage replacement and maintenance costs. Therefore, it does not meet the existing needs. Therefore, we propose the hot sealing drive assembly for packing equipment. UTILITY MODEL CONTENTS
