Description

Technical Field

[0001] The present invention relates to the technical field of cardboard production equipment, and more specifically, it relates to a corrugated cardboard turning device and its method. Background Art

[0002] In recent years, China's economy has developed rapidly, and the demand for packaging cartons in related industries has been increasing day by day. The carton industry has developed rapidly. Among them, corrugated cartons are packaging and transportation cartons made of corrugated cardboard, which have the characteristics of being light and firm. They can not only protect goods but also facilitate loading, unloading, and transportation, so they are widely used.

[0003] At present, during the production of corrugated cardboard on the market, according to customer requirements, patterns need to be printed on one side of the corrugated cardboard, and then the printed cardboard is turned over and bent, and finally formed into a carton. The existing cardboard turning devices generally first convey the printed cardboard to the turning position through a conveying device, and then manually turn it over by hand or turn it over through complex machinery. Manual turning has a large labor intensity and low efficiency. The efficiency of complex machinery turning has been partially improved, but the structure is complex and the operation is complicated. After the existing corrugated cardboard turning device turns over the cardboard, the operator needs to stack the cardboard manually. After the cardboard is stacked to a certain number, a transfer tool is used to transfer the cardboard stack, which is inconvenient to operate and has poor efficiency. When the conveying device conveys the cardboard, the cardboard initially falls on the conveying device and may not be aligned with the conveying direction, resulting in subsequent turning operation errors and damaging the corrugated cardboard.
