Extrusion molding process of plastic particles

Abstract

The invention discloses an extrusion molding process of plastic particles. The extrusion molding process comprises the following steps: heating and melting plastic fragments into molten state througha plastic melting device; enabling the molten plastics to pass through a material receiving hole, a connection pipeline, a material feeding hole, a material receiving groove, a shunting groove and anextrusion head in sequence, and extruding the molten plastics downwards in strip-shaped structures; enabling free ends of the strip-shaped plastics to finally fall and extend into a feeding area of apulley block, simultaneously dragging the strip-shaped plastics through rotation of the pulley block and enabling the strip-shaped plastics to extend downwards through extension holes in a base and befed; enabling the strip-shaped plastics to rotate along with the base and be in contact with a plastic cutter in the rotation process of the base, finally cutting the strip-shaped plastics into particle structures through the plastic cutter, subsequently enabling the plastic particles to fall into a water separation device right under the base, simultaneously enabling cooling water to flow into the water separation device through water discharging holes in the base, and carrying out separation treatment on the plastic particles and the water through the separation device.

Description

technical field [0001] The invention relates to the field of plastic recycling and reuse, in particular to a plastic granulation method.

[0002] Plastic recycling refers to the use of certain recycling processes to recycle and reuse waste plastics to achieve the purpose of turning waste into treasure. Products, plastic bags and agricultural mulch, etc. In the plastic manufacturing industry, various plastics in different forms are prepared into uniform granules that are convenient for subsequent processing through plastic granulator melting, extrusion, granulation, etc., but the existing The recycled plastic granulator has huge volume, high power consumption, low energy utilization efficiency, low production efficiency, the flow of molten plastic is prone to clogging, the metal filter for filtering impurities needs to be replaced and maintained frequently, and the cooling speed of strip plastic is slow and easy deformation, the size of plastic particles after cutting is inconsistent, the quality is low and affects subsequent sales, etc. Therefore, it is necessary for the present invention to provide a plastic granulation equipment, which sequentially heats and melts plastic fragments, filters impurities, melts State conveying, water-cooled strip forming, particle cutting treatment and plastic particles are obtained. During the impurity filtration process, the impurities can be transported away by the auger after being blocked by the filter, so that the filter avoids frequent replacement and maintenance; during the conveying process, the heating element It can keep the plastic in a molten state and be transported to the particle forming device, reducing the probability of clogging; during the water-cooled strip forming process, the cooling water is flowing water and the cooling water is turned over in a vortex manner, and the two cooperate to form a strip. The cooling molding effect of the plastic is better; during the particle cutting process, except for the first test run, the size of the plastic particles obtained during the subsequent normal operation of the present invention is consistent, no need for screening, the quality is better, and it is more convenient for subsequent sales. Cutting more plastic particles, better efficiency
