Description

Technical Field

[0001] The invention relates to the field of paper box production, and in particular to a box gluing machine and a box gluing method for producing corrugated paper boxes. Background Art

[0002] The folder gluer is a device used to fold and glue printed and die-cut cardboard. It is widely used in the gluing of packaging boxes for food, medicine, health products, cosmetics, alcohol, light industrial products, etc. After starting the power, the entire conveyor belt starts to move, and the die-cut semi-finished paper box is placed on the paper feed position of the folder gluer. The conveyor belt automatically feeds the single box piece into the middle belt according to the paper feed mark set by the paper stop head rack (if the semi-finished paper box has undergone surface treatment such as lamination or glazing, after entering the middle section, the paper box can be glued on the inner edge by a glue gun at the same time). The conveyor belt transports the paper box to the rear section of the box gluing area for pressurization.

[0005] The above patents and prior art also have the following defects:

[0006] The cartons are glued together in the box gluing machine. Two conveyor belts are needed to press the cartons at the tail end of the machine. The pressing force of the existing conveyor belts is consistent everywhere. If the pressure of the conveyor belts is too high, the glue may overflow when the glue is not dry at the beginning of the box pressing, which will affect the quality of the box gluing. If the pressure of the conveyor belts is too low, the box gluing machine will not be under pressure and the glue bonding effect will be poor. In addition, the cartons need to be packed in boxes after being pasted, which requires manual counting of the quantity, stacking and putting into boxes, which is troublesome to operate. In the process of putting the stacked cartons into boxes, they are easy to fall over and become messy, making them difficult to sort out.
