Description

Technical Field

[0001] The utility model belongs to the technical field related to product packaging, and in particular relates to a paper box outer skin laminating device and an all-in-one machine. Background Art

[0002] Product packaging refers to the general term for the decoration of products by using containers, materials and auxiliary materials according to certain technical methods in the process of product transportation, storage and sales in order to protect the products, facilitate storage and promote sales. The outer skin of the paper box is wrapped with packaging film, which is a common packaging method. It has a certain effect on water-proofing, dust-proofing and aesthetics. The current common all-in-one machine has the ability to make the packaging film stick to the outside of the paper box, but the inner edge of the paper box still needs to be taken out separately and the edge of the packaging film is manually pasted, which is not efficient.

[0003] In the patent document with the published patent number "CN104528030B" and the patent name "A paper sheet wrapping integrated machine", a paper sheet wrapping integrated machine is disclosed, which is characterized by:

[0004] The all-in-one machine includes a main pipeline, which includes a paper wrapping and forming conveyor line. The main pipeline has, in sequence along the conveying direction of the paper wrapping and forming conveyor line: a first paper folding station, at which a paper wrapping bottom preforming mechanism is provided, and the paper wrapping bottom preforming mechanism includes a left lower upper folding mechanism, a right lower upper folding mechanism, a paper folding front mechanism, a left rear folding mechanism and a right rear folding mechanism; a second paper folding station, at which a paper folding back mechanism, a left front folding mechanism, a right front folding mechanism and a packaging article packing station are provided.
