Description

Technical Field

[0001] The invention relates to the technical field of composite film production, and in particular to a production device and a manufacturing method for a printed composite film. Background Art

[0002] With the continuous development of the domestic printing industry and the gradual improvement of people's living standards, people have higher and higher requirements on the surface quality of industrial products such as plastics, glass, and metal. Taking the protective film used on the surface of household appliances as an example, the protective film needs to protect the outer surface of household appliances from external damage and chemical erosion, and also needs to make the appearance of household appliances beautiful. Therefore, the protective film needs to have good wear resistance, durability and aesthetics. Among them, PVC / PET composite film is a commonly used protective film. However, when the PVC / PET composite film in the prior art is manufactured, the surface printing of the PVC / PET composite film may miss printing or print out. There are mainly two situations: First, in the current composite film production process, the composite film printing quality is observed by human naked eyes, relying on the personal experience and subjective judgment of the staff, and the judgment of the composite film printing quality cannot be quantified. The quality consistency of the composite film produced is poor, and the production efficiency is low and the labor intensity is high when relying on manual judgment; Second, the printing quality of the composite film is also affected by the printing coating. Mechanical stirring or simple mixing equipment is generally used in the industry to pre-treat the coating, but these methods are often difficult to achieve the ideal dispersion effect, especially when the coating contains pearlescent powder and other difficult-to-disperse components, it is difficult to break the agglomeration of particles such as pearlescent powder, and the uneven dispersion of the coating will lead to damage to the printing quality and stability, which will cause the composite film to have a print out phenomenon, making the surface color of the composite film uneven, seriously damaging the appearance of the composite film, reducing the quality grade of the product, resulting in unnecessary waste of resources, and increasing production costs.
