Description

Technical Field

[0001] The patent of this invention relates to the technical field of packaging box sealing, in particular to a wet kraft paper box sealing machine. Background Art

[0002] A carton sealer is a commonly used packaging machine, mainly used to seal cartons or paper boxes. It is suitable for stand-alone operation or to form an automated packaging line with a carton opener, a case packer, etc. It uses sealing tape to seal cartons and can seal both the upper and lower sides of the carton at the same time. It has the characteristics of fast packaging speed, high efficiency, and beautiful appearance. When using the carton sealer, it first uses a belt to clamp the packaging box, then uses a height measuring wheel to measure the height of the packaging box, adjusts the height position of the sealing machine core, and finally uses the sealing machine core to seal the packaging box with tape.
