Shuangli Machinery shares with youFilm head of film blowing machineHow to adjust as follows:

The mold is covered from top to bottom, that is, if it is thick, loosen the screw (tighten the thicker side harder). This is called a smooth-adjusting die. If it is a big mouth at the bottom and the upper die is inserted, it is to loosen the thin side and tighten the thick side. This is called counter-adjustment. The die head has 4 or 6 adjusting bolts, which are usually hexagon sockets. You can adjust them on the upper edge of the die head. As for the tightness or the looseness, the molds of different origins are different.

Cleaning method of film blowing machine die head

To clean the touch head and spiral body, apply paraffin or methyl silicone oil when cleaning, and then gently wipe the paste with 1000-mesh sandpaper until it is clean. When changing the material, adjust the temperature appropriately according to the material properties (there is a difference between the temperature of the return material and the pure material). After changing the screen, increase the extrusion volume and extrude the paste.

The key is that it is always best to add a little methyl silicone oil to the hopper a week during the production process, which can lubricate the screw die head and also play a role in mold cleaning.
