Description

Technical Field

[0001] The utility model relates to the technical field of carton sealing equipment, in particular to a carton sealing machine. Background Art

[0002] The carton sealing machine is a commonly used packaging machine. It uses sealing tape to seal cartons through the machine movement. It has a fast packaging speed and high efficiency. It is widely used in manufacturing industries such as home appliances, electronics, food, dairy products, oils, cosmetics, beverages, and electrical appliances.

[0003] The movement of existing carton sealing machines is usually arranged above and below the carton moving channel. When sealing, the tape on the movement is mainly adhered to the surface of the carton along the moving direction of the carton through the movement of the carton. Such carton sealing machines are usually only suitable for middle sealing operations on larger cartons. For tall and narrow cartons, this sealing method is likely to cause the carton to be pushed over. Therefore, tall and narrow cartons are currently mainly sealed manually, which has low sealing efficiency and high labor intensity. Utility Model Content
