Description

Technical Field

[0001] The utility model belongs to the technical field of label paper processing, in particular to a label paper production device. Background Art

[0002] Label paper is a kind of paper used for marking and sticking on objects. It usually has adhesive coated on the back so that it can be firmly attached to the surface of the object. Nowadays, label paper is increasingly used for product labels, logistics labels, warehouse management and food labels. Thermal label paper that can be printed portable by thermal printers is widely used in many fields.

[0003] The special feature of thermal label paper is that its surface is coated with heat-sensitive materials. The heat-sensitive materials will mix and react chemically at a certain temperature to develop color. When producing label paper, different equipment is required to coat the heat-sensitive materials and the adhesive backing. Transfer is required between the two processes, which not only reduces efficiency but also easily causes paper pollution. For this reason, we propose a label paper production device that can simultaneously coat the adhesive backing and the heat-sensitive material. Utility Model Content
