Description

Technical Field

[0001] The invention relates to the technical field of packaging box production equipment, and in particular to a packaging box gluing machine. Background Art

[0002] In the packaging and printing industry, the application of folder gluers is the last step in packaging box processing. It folds the printed and die-cut cardboard into shape and glues the edges. Machine folder gluing replaces manual folder gluing, reducing labor costs and improving efficiency. Folder gluers are divided into paper feeding section, pre-folding section, bottom hook, forming section, and box pressing section. Folder gluers are divided into smooth-gluing folder gluers, bottom hook folder gluers, etc. according to their functions. They can realize automatic folding, gluing and pressing of cardboard to make it a complete packaging box structure, greatly improving production and processing efficiency.

[0003] The existing box gluing machines have the following drawbacks when in use: gluing is one of the important processes in the production process of the box gluing machine. The glue is applied to the position where bonding is required through the gluing equipment. The box gluing machine will be debugged before production operation, and production will be carried out after the debugging is completed. In the actual production process, as the production time increases, the quality and accuracy of gluing may decrease due to mechanical vibrations, glue residues on the surface of the gluing wheel, etc., and glue leakage may easily occur after gluing. Failure to make timely adjustments may easily lead to a large number of boxes with unqualified gluing. For this reason, we propose a box gluing machine. Summary of the invention
