▎ 摘　　要

NOVELTY - The device has an adjusting mechanism (3) which comprises an impeller. The outer side of the impeller is rotatably connected with a first flow passage. The outer side of the flow passage one is fixedly connected with with a graphene alloy (33). The outer surface of the grapheme alloy is fixedly connected with a solenoid one (34). The inner portion of the solenoid one is slidingly connected with a solenoid two. The bottom end of the solenoid is fixedly connected with an outer die lip (36). The graphene alloy is provided with a second flow passage (37). USE - Plastic forming device for realizing automatic adjustment of machine head film lip gap. ADVANTAGE - The plastic forming device for realizing machine head film lip gap automatic adjusting, enters from the spherical cavity opened in the inner part of the outer mold lip through the air flow, through the second flow passage is pressed, high speed airflow away residual melt, reduces the forming rate of curing material, improves the accuracy of the spraying film die, reduces laser cleaning cost, through Bernoulli principle, so that the inner flow passage three avoids blocking, avoiding uneven mould head spraying film, at the same time, using high temperature nitrogen to heat the melt, reducing the maintenance costs head inner heating rod, and avoiding the melt adhesive pipe wall. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a plastic forming device for realizing automatic adjustment of machine head film lip gap. Adjusting mechanism (3) Graphene alloy (33) Solenoid one (34) Outer die lip (36) Second flow passage (37)
