Principle of automatic box sealing machine
Automatic packaging machine is one of the components of automatic packaging production line. Its main function is to automatically seal the boxed products and complete the last process of product packaging.

Main components: height adjusting mechanism, flattening mechanism, box conveying mechanism, width adjusting mechanism, frame, hot melt adhesive system, etc.

Working principle: after the product is boxed, it is sent to the box sealing machine by the conveyor chain (belt and roller) and submitted to the box delivery mechanism. Both sides of the carton are clamped by the clamping belt and move forward. The front short tongue is automatically bent by the tongue presser. When the carton enters the drum of the sealing machine, the detection signal (photoelectric signal) informs the tongue beater cylinder to act, and the tongue beater bends it, and at the same time signals the glue melter to spray glue automatically. The carton continues to move forward, and the left and right long tongues automatically bend to the middle through the guide rod. At the same time, the belt of the box pressing mechanism presses the left and right long tongues of the carton synchronously, so that the carton, tongue and tongue are bonded together to complete the plastic action of box sealing, that is, the last process of product packaging-automatic box sealing.
