Polyethylene modified plastic pelleting processing preparation method

Abstract

The invention relates to a polyethylene modified plastic pelleting processing preparation method. The plastic pelleting processing preparation method adopts a following plastic pelleting processing device, the plastic pelleting processing device comprises a bottom plate, a transmission mechanism, a cooling mechanism, a trowelling mechanism and an air cooling pump, and the cooling mechanism comprises a material feeding box, material feeding baffles, cooling pipes, an air pump, an air blowing pipe, an air pump support and a cooling support. The polyethylene modified plastic pelleting processingpreparation method adopting the plastic pelleting processing device comprises the following steps of S1, particle feeding; S2, falling cooling; S3, thorough cooling; and S4, even material spreading. By means of the polyethylene modified plastic pelleting processing preparation method, the problems in cooling treatment performed by existing plastic particle cooling equipment that plastic particlescannot make sufficient contact with cooling wind power to cause the poor cooling effect and the plastic particles have high adhesion rate in the cooling process to cause the low product quality can besolved.

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...

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
