Description

Technical Field

[0001] The utility model relates to the technical field of plastic film drying, in particular to a plastic film drying device. Background Art

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is usually used for packaging and covering films, such as beverage packaging and food packaging, which have brought great convenience to people's lives. When the plastic film is produced and printed, the printed pattern needs to be dried on the surface to prevent the pattern from being embossed and staggered after being rolled up later. Therefore, the plastic film needs to be dried.

[0003] The existing announcement number is CN212949701U, and the name is a plastic film printing drying equipment, which includes a bottom plate, a drying box and a bracket fixedly connected to the upper end of the bottom plate, rectangular openings are opened on the left and right opposite side walls of the upper end of the drying box, and the inner walls of the front and rear opposite sides of the drying box corresponding to the rectangular opening are rotatably connected to a first guide roller through a rotating shaft, and the inner walls of the front and rear opposite sides of the drying box located in the middle and close to the lower side are rotatably connected to a second guide roller through a rotating shaft, and the same plastic film is driven and wound around the first guide roller and the second guide roller, and the inner walls of the front and rear opposite sides of the upper end of the bracket are rotatably connected to a winding roller through a pin shaft, and the outer wall of the bracket is fixedly connected to a winding motor, and the winding motor The output shaft is fixedly connected to one end of the pin shaft, and two inclined light boards are connected to the top inner wall of the drying box for symmetrical rotation. A plurality of drying lamps are fixedly installed on the lower side of the light board. A reciprocating adjustment mechanism for driving the light board to move is fixedly connected to the middle position of the top inner wall of the drying box. The plastic film printing and drying equipment enables the plastic film to be stably and smoothly conveyed in the drying box through the first guide roller and the second guide roller, and is reeled up by the winding roller. During drying, the conveyed plastic film is covered and dried by the drying lamp provided on the lower side of the light board, which can ensure the rapid drying efficiency and quality of the plastic film after printing, thereby improving the production efficiency of the plastic film.

[0004] However, after the above printing, the pattern ink on the plastic film is not solidified, resulting in the fluidity of the pattern ink on the plastic film. The above drying of the printed pattern ink is done by wind drying, and the air blows onto the pattern on the plastic film. The fast-flowing air causes the pattern ink on the plastic film to flow, resulting in the pattern on the plastic film being scattered, affecting the integrity of the pattern on the plastic film.
