Preparation method of PE recycled plastic particles

Abstract

The invention discloses a preparation method of PE recycled plastic particles. A main body, a detection mechanism and a cleaning box are included, the cleaning box is located on the outer surface of one side of the main body and fixedly connected with the main body, a cooling groove is formed in the outer surface of the upper end of the main body, the detection mechanism is located on the inner surface of the cooling groove and fixedly connected with the cooling groove, three supports are fixedly connected to the outer surface of the upper end of the main body and located on the two sides of the outer surface of the upper end of the main body and the outer surface of the upper end of the cleaning box correspondingly, and first rotating shafts are fixedly connected to the inner surfaces of the supports. According to the preparation method of the PE recycled plastic particles, isolating can be carried out on plastic rods which are just formed through extrusion in the production process, the situation that the production quality of products is reduced due to the fact that the plastic rods which are just produced adhere to one another is avoided, and the plurality rotating shafts are arranged between the cooling groove and the cleaning box, and therefore the plastic rods passing through the interior of the cooling groove can be always kept spaced.

Description

technical field [0001] The invention relates to the technical field of PE recycled plastics, in particular to a preparation method of PE recycled plastic particles. Background technique [0002] The granulator is mainly composed of feeding, stirring, granulating, transmission and lubrication systems, etc. It is widely used in the pharmaceutical, chemical and food industries. The granulator can be divided into a feed granulator and a biomass energy granulator. Machines are also relatively common mechanical equipment in life, and plastic pellet production equipment is also used in the production process of plastic pellets. [0003] Existing patent (notification number: CN209937646U) a cooling conveying device for a modified plastic particle production line, including a cooling pool and an inclined pool, the cooling pool includes a first pool body and a second pool body, the first pool body The cooling liquid temperature is lower than the cooling liquid temperature in the seco...

Problems solved by technology

[0005] 1. When making plastic granules, it is first necessary to heat-melt the plastic, and then extrude it to form a long plastic rod, and then start cooling. After cooling, it can be cut directly. After the cutting is completed , can form plastic particles, but in the production process, the extruded plastic rod itself has just been melted and then formed into strips. After extrusion, the plastic rod enters the cooling tank and cannot be condensed in a short time. , Adhesion will occur between adjacent plastic rods. The existing methods are artificially fiddled with this situation, which is inefficient and cannot be adjusted in time when the adhesion is serious, resulting in a decline in the quality of plastic pellet production.

[0006] 2. When plastic granules are produced, especially in areas with a lot of sand and dust, the production of plastic granules needs to be hot-melted, and then extruded into a rod shape. After cooling in the cooling tank, the plastic that has passed through the cooling tank Plastic particles can be obtained by shearing the rods. Therefore, the plastic rods in the cooling tank need to be kept clean and tidy. Clean up in time. During the cutting process, the debris attached to the surface of the blade and the plastic rod will be damaged after frequent friction, which will reduce the shearing effect.
