A kind of preparation method of polyethylene modified plastic granulation processing

Abstract

The present invention relates to a polyethylene modified plastic granulation processing and preparation method. The plastic granulation processing and preparation method adopts the following plastic granulation processing device. The plastic granulation processing device includes a bottom plate, a transmission mechanism, a cooling mechanism, a smoothing mechanism, Air-cooled pump; the cooling mechanism includes a feed box, a feed baffle, a cooling pipe, an air pump, a blower pipe, an air pump support, and a cooling support; the polyethylene modified plastic granulation process using the appealing plastic granulation processing device The preparation method comprises the following steps: S1, particle feeding; S2, falling cooling; S3, thorough cooling, S4, evenly spreading the material. The invention can solve the problems that the plastic particles cannot fully contact with the cooling wind when the existing plastic particle cooling equipment is cooling, which leads to poor cooling effect and the high adhesion rate of the plastic particles during the cooling process, resulting in low product quality.

Description

technical field [0001] The invention relates to the technical field of plastic granulation processing, in particular to a preparation method for polyethylene modified plastic granulation processing. Background technique [0002] Due to the process of plastic extrusion and granulation, which needs to go through technological steps such as heating up and mixing, high-speed shearing, etc., the granules finally discharged from the plastic extruder usually have a high temperature, and they need to be placed for cooling before loading. If they are directly loaded, it will easily cause Particle adhesion, scalding storage bags, etc. In addition, prolonged high temperature may also cause oxidative discoloration. It takes a long time for plastic pellets to be placed and cooled, which greatly reduces production efficiency. Insufficient cooling causes particles to stick together and needs to be broken again during use, which increases the workload. Therefore, it is necessary to cool th...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing wind cooling machine needs to consume a lot of time in use, the production efficiency is low, and the plastic particles cannot be completely cooled, and the various surfaces of the plastic particles cannot be fully contacted with the wind force, resulting in easy cooling dead angles. During the cooling process, the plastic particles are easily stuck together, resulting in lower product quality;

[0005] 2. When the existing liquid cooling equipment cools the plastic particles, the plastic particles are easily adhered to the inner wall of the cooling equipment. After working for a period of time, it is necessary to manually clean the plastic particles adhered to the inner wall of the equipment, which increases production labor. The amount reduces the cooling efficiency, and the plastic particles are more likely to stick to each other during cooling
