Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a swing arm box suction device. Background Art

[0002] A cartoning machine is a device that semi-automatically or automatically loads unpackaged products or small-packaged products into transport packaging. Its working principle is to load products into boxes in a certain arrangement and quantity, and automatically close or seal the opening of the box. It is widely used in product packaging in industries such as food and beverage, and pharmaceuticals. In the prior art, a cartoning machine is one of the main equipment for post-packaging. Before the carton or paper box is formed, the paperboard is sucked from above by a paper suction mechanism, and then the paperboard is transferred to a group of packaging bottles.
