[0063] Example 1:
[0064] There are four beams and three lead screws in the film flattening mechanism. The three lead screws are respectively connected with the upper and lower beams, and the other end of the lead screws is connected with the auxiliary frame.
[0065] The method of flattening the plastic film on the line side is:
[0066] The first step is to add the raw material into the hopper, heat, plasticize and melt through the extruder and then enter the mold, extrude the annular blank in the annular forming section of the mold, and fill the blank with compressed air to form a film bubble;
[0067] The second step is to introduce the film bubble into the herringbone splint and then enter the traction roller, and squeeze it into a cylindrical film;
[0068] The third step is to slide on the horizontal sliding bar through the knife holder chute with the slitting knife. The slitting knife cuts the single side of the cylindrical film into a single piece of film. roller; ...
