AI Technical Summary
The peeling force of PET film is relatively high, which may be due to the presence of pollutants such as dust on the substrate surface that affect the adhesion of the coating. Existing equipment is difficult to effectively remove these pollutants.
A dust removal equipment was designed. By setting wind hoods on the upper and lower transmission rollers and connecting them to bellows, a suction fan was used to remove dust. The position of the wind hood was adjusted by a swing arm and a driving cylinder to ensure the best suction effect. Combined with the driving mechanism to drive the roller transmission, efficient cleaning was achieved.
It effectively removes dust from the surface of the film, improves the adhesion of the coating, reduces the peeling force of the PET film, and ensures the effect of the subsequent coating process.
