Plastic pelletizing device

Abstract

The invention discloses a plastic pelletizing device. The plastic pelletizing device comprises a base, an extrusion cylinder and a screening chamber. The extrusion cylinder is fixed to the base through a supporting rod, and the screening chamber is fixed to the base and located below the extrusion cylinder. The extrusion cylinder comprises a cylindrical barrel body, a heating and feeding hopper and a hot air chamber are arranged on the top of the extrusion cylinder, the lower end of the heating and feeding hopper communicates with the interior of the extrusion cylinder, a combustion cavity isformed in the hot air chamber, and the hot air chamber communicates with the heating and feeding hopper through an air supply pipe. The plastic pelletizing device is exquisite in structure, can conduct step-by-step screening on pelletized particles, and conveniently conducts collection and reprocessing in the later period. Due to the arrangement of a plurality of pipelines in the material fallingprocess, the operation of quick cooling, energy recycling and the like can be conducted, the energy utilization rate is greatly improved, and the pollution is reduced. The situation that tool edges ofmaterial cutting tools are sharp, and the material cutting tools rotate at a uniform speed can be guaranteed by means of the arrangement of sliding pieces and a material scraping block, and thereforethe specification of pelletizing is guaranteed, and then the percent of pass of products is guaranteed.

Description

technical field [0001] The invention relates to plastic processing, in particular to a plastic granulation device. Background technique [0002] Plastic processing, also known as plastic molding processing. It is a general term for various processes that convert synthetic resin or plastic into plastic products, and is a large production department in the plastics industry. [0003] Plastic processing generally includes plastic ingredients, molding, machining, joining, modification and assembly; the key link of plastic processing. Various forms of plastics (powder, pellets, solutions or dispersions) are made into products or blanks of the desired shape. There are more than 30 methods of molding. [0004] For the utilization of waste plastics, most of them are further processed after hot-melt granulation.

Problems solved by technology

[0004] For the utilization of waste plastics, most of them are further processed after hot-melt granulation. Pelletization is the primary processing process for the utilization of waste plastics, which is essential. contact, resulting in the accumulation of material at the knife edge, which directly affects the granulation specifications, and requires frequent cleaning, which is very inconvenient. In order to ensure that the raw materials are fully melted and do not change their properties, hot air hot melting is usually used, and fuel combustion is required, and the remaining in the hot air The heat energy and the flammable gas such as carbon monoxide produced by incomplete combustion will be wasted, which not only wastes energy, but also causes environmental pollution.
