Description

Technical Field

[0001] The utility model relates to the technical field of PET film production, in particular to a film material surface inspection device. Background Art

[0002] PET film is a packaging film with relatively comprehensive performance. PET film has good transparency and glossiness; it also has good air tightness and fragrance retention; moisture resistance, excellent heat resistance, cold resistance, good chemical resistance and oil resistance, etc. After the PET film production process is completed, the surface of the PET film needs to be tested.

[0003] After searching, Chinese patent announcement number CN216646262U discloses an automatic detection system for surface defects of PET protective film, which relates to the field of PET protective film. The utility model includes a detection box, both sides of which are fixed with brackets, a motor is installed on the top of the bracket, and a winding roller is connected to the output end of the motor. Dust removal components are arranged on both sides of the detection box, and a cylinder is installed on the top of the detection box. The utility model is provided with a dust removal component. When the protective film passes through the dust removal brush, the dust removal brush can sweep the dust on the top and bottom of the protective film. After that, when the protective film passes through the guide roller, the friction formed between the movement of the protective film and the guide roller can drive the guide roller to rotate, and the rotating guide roller can tighten the protective film through multiple rubber pads. At the same time, multiple sponge blocks can further contact the protective film to adhere dust and impurities, so that the subsequent detection of the protective film is safer and more accurate, and the situation that dust and impurities attached to the surface of the protective film affect the detection accuracy is avoided.

[0004] However, in the above technical solution, the dust on the surface of the protective film is removed only by the contact between the dust removal brush and the protective film, and the dust impurities are further adsorbed by multiple sponge blocks. When the sponge block is cleaning, the dust at the bottom of the protective film will fall or be adsorbed on the sponge block, and the dust on the top of the sponge block cannot fall into the inspection box and can only be attached to the sponge block. After a certain amount of dust is adsorbed on the surface of the sponge block, its cleaning effect will gradually decrease, resulting in a large amount of dust on the protective film affecting its surface inspection.
