Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a capping device for a carton packaging machine. Background Technology

[0002] In the field of modern logistics packaging, carton packing machines are key equipment in automated packaging lines, and the stability and adaptability of their capping devices directly affect packaging efficiency and product quality. With the rapid development of e-commerce logistics, the specifications of packaging cartons are becoming increasingly diverse, placing higher demands on the compatibility of packing machines. In particular, in the carton flap pressing process, traditional capping devices often struggle to adapt to the differences in flap angles between cartons of different sizes, easily leading to problems such as incomplete sealing and carton deformation.

[0003] In existing technologies, the capping device of a carton packing machine typically adopts an integral pressure plate structure, using hydraulic or pneumatic pressure to drive the pressure plate to perform a vertical pressing action to complete the capping. These devices generally include a guide mechanism at a fixed height, using mechanical limits to control the pressing depth. Their working principle involves using preset pressing stroke and pressure parameters to bring the pressure plate into contact with the carton lid and apply constant pressure until the flap is fully closed. When processing cartons of different heights, the flap often exhibits varying degrees of bending and deformation before entering the main pressing area. This is especially problematic when processing large or thick cartons, where the flap's higher rigidity makes it more prone to springback, severely impacting the packaging pass rate. Therefore, this paper proposes a capping device for a carton packing machine to address these issues. Utility Model Content
