Pressurized molding process for plastic particles

Abstract

The invention provides a pressurized molding process for plastic particles. The process comprises the following steps that firstly, a plastic granule cutting machine body carries out hot melting on waste plastic and extrudes the waste plastic into a butt joint pipe, so that molten plastic flows into a pressurizing cylinder, at the moment, a piston is driven to slide along the pressurizing cylinderin a reciprocating mode, when the piston slides into the pressurizing cylinder, the molten plastic in the pressurizing cylinder is extruded towards an extrusion part B, the pressure of the molten plastic is increased and the molten plastic is extruded from a butt joint hole; meanwhile, the pressurizing cylinder is driven to swing back and forth to move relative to cutting knives, and the cuttingknives cut the extruded strip-shaped plastic, so that the extruded strip-shaped plastic is cut into plastic particles and then falls down; then, the plastic particles fall into a water-cooling conveying device, and the water-cooling conveying device carries out water-cooling temperature reduction on the plastic particles and conveys the plastic particles to an air-drying and discharging device after tap water is filtered; and finally, the air-drying and discharging device carries out air-drying on the wet plastic particles and discharges the plastic particles outwards for collection.

Description

technical field [0001] The invention relates to a plastic granulator, in particular to a pressurized molding process for plastic granules. Background technique [0002] With the smooth development of energy saving and environmental protection, people pay more and more attention to and research on waste recycling. In the plastic industry, plastic granulator waste plastic recycling industry is the most widely used, most widely used, and most popular plastic recycling processing. Machinery, plastic granulator is mainly used for processing waste plastic films (industrial packaging films, agricultural mulch films, greenhouse films, beer bags, handbags, etc.), woven bags, agricultural convenience bags, pots, barrels, beverage bottles, furniture, daily necessities etc., suitable for most common waste plastics. The plastic granulator is mainly composed of a plastic granulator body and a detachable machine head. The plastic granulator body mainly crushes and melts waste plastics, and...

[0002] With the smooth development of energy saving and environmental protection, people pay more and more attention to and research on waste recycling. In the plastic industry, plastic granulator waste plastic recycling industry is the most widely used, most widely used, and most popular plastic recycling processing. Machinery, plastic granulator is mainly used for processing waste plastic film (industrial packaging film, agricultural mulch film, greenhouse film, beer bag, handbag, etc.), woven bags, agricultural convenience bags, pots, barrels, beverage bottles, furniture, daily necessities etc., suitable for most common waste plastics. The plastic granulator is mainly composed of a plastic granulator body and a detachable machine head. The plastic granulator body mainly crushes and melts waste plastics, and the machine head mainly The molten plastic is extruded, pelletized, cooled, etc. However, because the pressure of the molten plastic in the plastic pelletizer body is small, the efficiency of extrusion from the machine head is low, which will directly affect the productivity of plastic pellets. In order to overcome the above disadvantages, it is necessary to provide a single pendulum piston pressurized high-efficiency extrusion pelletizing method for a plastic pelletizer that has an ingenious structure, simple principle, convenient operation and use, and can improve the plastic pelletizing efficiency.
