Description

Technical Field

[0001] The utility model relates to the technical field of packaging structures, in particular to a handheld packaging structure for a PU film. Background Art

[0002] The sealing mechanism is used to close cartons automatically or semi-automatically. It is generally divided into handheld, semi-automatic and fully automatic ranges. The handheld carton sealing mechanism is the most common handheld carton sealer on the market. It is the most basic carton sealing tool. It is usually held by the operator, who manually fixes the tape on the box and smoothes the tape with a pressure wheel or pressure plate. It is suitable for small-scale or temporary packaging tasks.

[0003] The automatic and fully automatic packaging structures automatically complete the cutting and fixing of the tape. The difference is that the semi-automatic packaging structure requires manual loading of the items into the box, which is then sent to the semi-automatic packaging structure for packaging; while the fully automatic packaging structure can independently complete the transportation, positioning and packaging of the box; both are used in large-scale production lines and high-speed packaging lines.

[0004] The existing handheld box sealing structure on the market has an exposed sharp blade, so it is easy for the hands to be scratched due to improper operation during use. Not only will the workers' hands be injured, but the wounds will also affect the work efficiency and convenience of the subsequent workers. Therefore, in order to solve the above problems, the utility model proposes a handheld packaging structure for PU film. Utility Model Content
