The plastic film blowing machine is a machine for manufacturing granular plastic materials into plastic film. The working process is as follows:
A plastic material is added to the feed port while heating the main screw and the rotary die. When the temperature values ​​reach the set value, the machine is started. At this time, the plastic material that has been melted at a high temperature is extruded by a ring-shaped rotary die under the driving of the main screw, and the extruded film is drawn by the air-cooled and water-cooled wheels. After being embossed by the embossing wheel A and the embossing wheel B, it is introduced into the curling wheel by the introducing wheel, and finally the film is wound into a roll of the finished product by the curling wheel.
Within the range of film forming conditions of the plastic film blowing machine, the molding temperature, the cooling air temperature and the inflation ratio are increased; then the film turbidity is increased and the gloss is lowered;
When the die blower of the plastic blown film machine is uniform and uniform, the glove can be slowly pulled to pull the blank, and the end of the blank is closed, and the intake regulating valve is slightly opened to put a small amount of compressed air from the center hole of the mandrel. Then carefully guide the bubble holder, the herringbone plate, and penetrate the traction roller and guide roller until the coil is taken up.
