Introduction of the components of the film blowing machine

Blow Membrane is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film. Usually, the polymer is extruded to form a tubular film blank, which flows in a better melt flow. In the state, the tube film is blown to the required thickness by high-pressure air, and it becomes a film after being cooled and shaped. The quality of the film material blown by this process is related to the film blowing machine and plastic particles. Film blowing machine is a machine that heats and blows plastic particles into plastic film. The film blowing machine has the advantages of simple structure, low investment, and quick product effect; high mechanical properties of the film; no edge material and less waste; the film product is cylindrical and the bag-making process is simple; it can produce a wide film.

The separation type screw divides the melting section into a solid bed and a melt bed. The width and depth of the solid bed gradually become smaller, and the width and depth of the melt bed gradually become larger, and finally become the width and depth of the metering section.

1. Feed zone.The volume of the screw groove in the feeding section remains unchanged. The material is in a solid state, and the main purpose is to transport the material forward as soon as possible.

2. Melting zone. The volume of the screw groove in the compression section gradually decreases. The material changes from solid to molten. The main purpose of the material is to change from solid to molten.

3. Melt pumping zone.The volume of the screw groove in the metering section remains unchanged. The material is completely in a molten state, and the main purpose is to make the material fully plasticized and send the material to the machine head at a fixed amount and pressure.
