Extrusion granulation equipment for plastic recycling and processing and operation method thereof

Abstract

The invention discloses extrusion granulation equipment for plastic recycling and processing. The equipment comprises a bearing frame body, a granulation mechanism and a cutting collection device. Thegranulation mechanism comprises a water cooling device, a screw rod device and an extrusion device, the screw rod device comprises a screw rod, one end of the screw rod is connected with the output end of a cycloidal pin wheel speed reducer through a coupler, the screw rod is positioned in a cylindrical shell, and the cylindrical shell is fixed on a second vertical plate in a penetrating manner;the extrusion device comprises an orifice plate, the orifice plate is embedded on the inner surface of the circumferential side of the cylindrical shell, extrusion holes are uniformly formed in the surface of the orifice plate, plastic is extruded through the extrusion holes to form strips, and then the strips enter the cutting collection device through a granulation plate to be cut into granules.After the screw rod is connected with the cycloid pin wheel speed reducer, the rotating speed of the screw rod is conveniently adjusted, the rotating speed of the screw rod influences the advancing speed and the mixing degree of plastic, waste plastic can be extruded in one step and cut into granules, the automation degree is high, the granulation efficiency is high, the investment cost of enterprises is reduced, and the benefits are improved.

Description

technical field [0001] The invention belongs to the field of plastic recycling, and in particular relates to an extrusion granulation equipment for plastic recycling and an operation method thereof. Background technique [0002] With the development of industry, the application of plastic products has spread all over the fields of industry, agriculture and daily life. The waste plastic products processed every day in the world are immeasurable. Waste plastics can only be disposed of by landfill or incineration, which is very harmful to the environment. Therefore, resource utilization of waste plastics is a better solution. The current The most common way to recycle waste plastics is to recycle and granulate. [0003] The Chinese Utility Model Patent No. CN201621440637.3 discloses a recycling and granulation system for waste plastics, including: a screw feeding device, a crushing device, a screening device, an intermediate conveying device and a granulating device. The crush...

Problems solved by technology

However, the application did not refine the specific granulation. The traditional granulation method is used to granulate plastics. The granulation efficiency is low, and the mixing degree cannot be adjusted for different types of waste plastics, which affects the granulation efficiency.
