Description

Technical Field

[0001] The utility model belongs to the field of film processing, in particular to an extrusion device for film processing. Background Art

[0002] Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging and fast food packaging. These products have brought great convenience to people's lives. Several common films include biaxially oriented polypropylene film, low-density polyethylene film, polyester film, nylon film, cast polypropylene film and aluminized film.

[0003] After searching, a Chinese patent discloses a hot melt extrusion device for processing film packaging materials (authorization announcement number CN219445744 U). The patent technology includes a box body, a glue squeezing mechanism is arranged inside the box body, a glue inlet pipe is connected to the upper surface of the box body, a fixing plate is vertically fixed on the right side of the box body and close to the top surface of the box body, and two heating tubes are fixed on the lower surface of the fixing plate. The glue squeezing mechanism includes a double-axis motor fixed to the left wall of the inner cavity of the box body, a connecting rod is fixed to the outer side of the output shaft at the right end of the double-axis motor, a rotating drum is fixed to the right end of the connecting rod, and a first gear is fixed to the outer side of the rotating drum and located in the box body. The hot melt extrusion device for processing film packaging materials uses a movable sleeve to move horizontally to the right to push the piston plate and the hot melt glue introduced by the glue inlet pipe to the right. When the hot melt glue moves to the glue dripping hole on the right side, the hot melt glue penetrates outward through the glue dripping hole. The hot melt glue can be heated by two heating tubes to prevent the hot melt glue from solidifying.

[0004] In this technology, a screw is used to drive a piston plate to move, thereby pushing and extruding the hot melt adhesive through the piston plate to achieve the purpose of gluing the film packaging material. However, only a single film packaging material can be glued at a time. When gluing the next film packaging material, it is necessary to wait for the piston plate to move back to its original position and then push the hot melt adhesive again. The working efficiency is low, and the film packaging material needs to be held with external tools or manually and placed between the glue dropper and the rotating drum. It is more troublesome to use. Not only can it not continuously glue multiple film packaging materials, but it is also necessary to align the film packaging material with the glue dropper, otherwise it will cause uneven gluing, and the practicality is low.
