Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a glue supply and discharging structure of a coating machine. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. This machine coats a roll of base materials with a specific functional glue, coating, ink, etc., and then winds it up after drying. A coating machine is a machine for coating roll-shaped materials with coatings such as glue or pigments. When different materials need to be coated with glue, the required coating thickness is usually different. Therefore, it is necessary to adjust the coating thickness. Usually, a scraper is used to scrape off the too thick glue layer to achieve a uniform glue layer, and the glue layer thickness is adjusted by adjusting the scraper. However, when adjusting the coating thickness of the existing coating machine's coating mechanism, usually one side is scraped. When encountering materials that need to be coated on both sides, due to the characteristics of the glue, after using for a period of time and the glue solidifies, the scraper must be cleaned or replaced. However, the existing scraper is fixed on the device and is difficult to replace. Publication number: CN212791659U, a glue supply and discharging head for a coating machine, includes a pipe body and a speed regulating device arranged inside the pipe body. The speed regulating device includes an automatic control mechanism, a transmission mechanism, and an adjusting mechanism connected in sequence. The automatic control mechanism includes a strip-shaped cabin filled with a temperature-sensitive fluid material inside. The adjusting mechanism includes a blocking disk arranged perpendicular to the central axis of the pipe body and an expansion ring arranged on the outer side surface of the circumference of the blocking disk. The expansion ring is made of an elastic material and is filled with a non-temperature-sensitive fluid material inside.

[0003] In the above-mentioned prior art, the glue supply and discharging are prone to the phenomenon of uneven glue supply and discharging, which further leads to uneven coating and reduces the quality of the processed products. Summary of the Utility Model
