Description

Technical Field

[0001] The utility model relates to the field of strapping machines, in particular to a strap body processing tool mechanism. Background Art

[0002] The fully automatic strapping machine is a fully automatic strapping equipment. When working, you only need to move the packaged material to the work surface to trigger the automatic switch on the table to automatically strap. The number of straps can be selected according to the packaging requirements. It can also be designed into various types such as power type or side-beating type according to the user's production line to meet the requirements of different users.

[0003] When the existing strapping tape is used to bundle items, it generally goes through the steps of wire wiring, winding, wire pressing, ironing (or riveting) and shearing. Therefore, the wire pressing process of the strapping tape also includes processes such as pressing and tightening. Therefore, multiple tools are required to cooperate simultaneously. During operation, the existing tools are generally controlled by multiple driving devices respectively, and the distances between the positions of the corresponding tools are also large, so the overall size of the tool is large.
