TECHNICAL FIELD
[0001] The utility model provides a film covering mechanism relates to packing box production equipment field, specifically relates to a packing box edge automatic film covering mechanism. BACKGROUND
[0002] The packing box is usually used for the packing of articles, and is mostly rectangular for easy stacking. In order to make the packing box more beautiful or prevent it from being stained, many packing boxes are subjected to film covering processing. However, the surface of some packing boxes already has a film covering layer, and the edges of the packing boxes are more likely to be scratched or penetrated by water vapor.
[0003] The film covering equipment of the prior art is usually used for overall film covering. The film covering of the edges saves at least more than 55% of the film covering material compared to the overall film covering processing. However, when the edges are subjected to film covering, the film covering and the edges cannot be accurately positioned, the film covering is easy to slip off, and the distribution of the film covering cannot be easily controlled when the film covering is heated and shrunk.
[0004] Therefore, the technical personnel in the art propose an automatic film covering mechanism for the edges of a packing box, which is designed in accordance with the film covering needs of the edges to ensure that the film covering is accurately positioned on the edge portions during the film covering process.

The mechanism includes a conveyor belt and a film covering roller. The film covering roller is used to cover the packing box on the conveyor belt. The film covering of the conventional method is usually overall film covering of the packing box. For some packing boxes that already have a film covering layer, the film covering of the edges of the packing boxes is of little significance. If the film covering is only performed on the edges of the packing boxes where water is easy to enter, the film covering loss can be reduced by at least 55%.
