[0002] In the carton production process, the molding accuracy and speed are a big problem. The reason is that in the high-speed production process, stapling has extremely high requirements on the previous molding process. The stapler is one of the post-processing equipment of the carton. Its principle is the same as that of the ordinary stapler, except that the stapler uses tiger teeth as a pad. It is specially used for carton sealing and is widely used in the sealing of various cartons and calcium plastic boxes that need to load heavier items or are not easy to seal with adhesive tape.

[0003] In the production process of the existing carton stitching machine, as long as the stapling is started, it means the result of forming, and it cannot be corrected after stapling. Therefore, a large number of high-quality cartons cannot be completed in a fully automatic production mode, and the production of such products depends on manual or semi-automatic production, resulting in low production efficiency and high production cost, which affects the overall adaptability effect. Therefore, it is urgent to improve the technology of the carton stitching machine structure to improve this equipment. Utility Model Content
