Then, the connecting column is driven to rotate by the second reduction motor, and the connecting column rotates with the fan blades. The rotation of the fan blades generates wind force, and the wind force is heated between the heating rollers. Then, the heat acts on the surface of the packaging box, which can dry the glue at the adhesion of the packaging box, which is beneficial to improving the bonding efficiency of the packaging box.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] (1) In the present application, heat is generated by the heating roller through the setting of the heating and drying component, and then the fan blades are driven to rotate by the second reduction motor to generate wind force.
