Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to a top edge wrapping device. Background Art

[0002] In the production process of gift boxes, thicker cardboard with a certain hardness is required as the shell material, and its surface is wrapped with leather. The wrapping process is divided into side wrapping, bottom wrapping and top wrapping. When wrapping the top edge, the soft leather on the top edge of the board passes through the bending structure of the flipping mechanism to form a back bend, and then passes through the upper brush and lower roller structure (i.e., the smoothing mechanism) for smooth and neat fitting, and finally passes through the upper and lower pressure roller groups to complete the pressing and complete the top edge wrapping process.

[0003] However, according to the needs of different customers, the thickness of the plates commonly produced is also divided into different models. In order to adapt to plates of different thicknesses, it is often necessary to repeatedly adjust the gap between the upper and lower pressure rollers according to the thickness of the plates, which is rather troublesome.
