Friction of a three-layer co-extrusion film blower

A film blower is a device that melts plastic particles and then blows them into a film. There are many kinds of film blowing machine, PE, POF, PVC, etc. The film blowing machine uses new plastic particles to blow out new material, whose color and color are all said, clean, and the bag is stretched well. The production process and production principle are to add dry polyethylene particles into the hopper, and the three-layer co-extruded film blowing machine enters the screw from the hopper by the weight of particles themselves. The rotating helical face of the plastic produces a thrust perpendicular to the helical face.

HDPE high speed film blowing machine film bubble temperature automatic adjustment device

The membrane bubble temperature automatic adjustment device of HDPE high-speed film blowing machine relies on changing the air volume to adjust the membrane bubble temperature specially and independently. Moreover, changing the air volume does not affect the air pressure in the cavity of the membrane bubble, and does not affect the blowing expansion ratio of the membrane bubble.

HDPE high speed film blowing machine rod damage reasons and maintenance

Cause of damage: The four pull rods in the die closing device of HDPE high-speed film blowing machine are fixed by nuts on the template frame at both ends. The four pull rods have the template of clamping molding mold sliding on the pull rod shaft, so that the pull rod is not only subject to axial tension, but also to the radial force of the mold. At the same time, the template is also sliding on it, so that the long-term tension, radial force and friction effect. The tie rod will appear working face wear, shaft bending deformation, and even fracture.

On the cold control system of pp film blowing machine

The internal cooling control of the film blowing machine is an important link in the system of the film blowing machine. The principle is that the cooled air is pumped into the film bubble pulled from the film head by the fan, which plays a rapid cooling effect on the hot film bubble and improves the steady-state effect of the film (finish). The size of the film bubble can be controlled by changing the air volume, that is, the width of the film. Other electrical parts are not introduced in this manual, please refer to them.
