Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a drying device of a film coating machine. Background Art

[0002] Coating machines are mainly used for surface coating production of films, papers and other materials. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and cuts it into sheets or rolls it up after drying. It uses a special multi-functional coating head and can achieve various forms of surface coating. The reel and unreel of the coating machine are equipped with full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.

[0003] After the coating is applied, the film coater needs to use a heater to dry the film to avoid damaging the coating layer when winding. Due to the different thickness and material of the film, the optimal distance between the heater and the film when drying is different. Due to the different material and spray thickness of the coating, the time and temperature required for the heater to dry the film are also different. The drying device of some existing film coaters fixes the heater on the upper side of the film drying channel, and the distance between the two cannot be adjusted, and it is impossible to adapt to films of different thicknesses and materials in a targeted manner. In addition, when some films are difficult to dry due to the material or spray thickness of the coating, the film drying time needs to be extended, which reduces the drying efficiency of the film. Therefore, a drying device for a film coater is proposed to address the above problems. Utility Model Content
