Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, in particular to a small PET film coating machine. Background Art

[0002] PET film is a packaging film with comprehensive performance. It has good transparency and gloss; good air tightness and fragrance retention; moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films. It also has good strength and stable dimensions, making it suitable for secondary processing such as printing and paper bags.

[0003] At present, PET film needs to be coated during its production and processing. After coating, the existing coating device will cause the coating roller to be stuck with residual coating liquid. After the coating liquid solidifies, it will affect the use of the next side. Therefore, after use, the coating roller needs to be cleaned. However, the existing device, because roller coating mostly uses more rollers and the gap between the rollers is small, it is inconvenient for staff to clean it manually and it is easy to cause accidents.
