Plastic Film Granulation Line Video

The plastic film granulation line is suitable for PP film, LDPE/HDPE/LLDPE film, etc. Firstly, the material is transported to the cutting and compacting machine by a belt conveyor. Through the mutual cutting between the moving blade on the cutting and compacting machine disc and the fixed blade on the cylinder wall, the material is crushed. At the same time, the friction between the materials and the friction between the materials and the equipment continuously increases the temperature inside the barrel. When the temperature reaches a certain value, the material will enter a semi plasticizing state.

At this time, it enters the feeding port of the extruder under the rotation of the disc. After passing through the heating and conveying section of the cylinder screw, plasticizing section and metering section, impurities in the material are separated by the filter of the screen changer. The material passing through the screen changer is melted into strips by the porous plate of the mold head, and the high-speed rotating cutter is used to move the material.

For the particles, they are cooled by a water ring, and the plastic particles and cooling water are discharged together through the discharge port of the water ring, and then by “S” Type water tank, entering the particle dewatering machine, separates plastic particles and water through the high-speed rotation of the dewatering machine spindle. The plastic particles are transported to the discharge port of the dewatering machine by the spindle blades, while the water returns to the water tank of the dewatering machine through the filter holes of the dewatering machine screen, and is then circulated by the water pump to cool the plastic particles in the water ring.

The desired particles that come out of the dewatering machine discharge port enter the vibrating screen for screening and separation, and are separated into plastic powder, normal particles, and oversized plastic particles.

They flow out through different outlets of the vibrating screen, and the normal plastic particles flow into the No. 1 mixer for uniform mixing. Then, they enter the spiral feeder through the discharge port and are transported to the No. 2 mixer. There is an additive on both sides of the No. 2 mixer. Spiral feeding port for new raw materials, They are all weighed by the weighing system on the four legs of the No. 2 mixing bin, then mixed evenly, and finally temporarily stored in the storage bin, ready to be transported to the next workflow.
