Abstract

The invention discloses a plastic waste film extrusion device based on a waste plastic secondary utilization technology. The plastic waste film extrusion device comprises a device body; an upper partition plate and a lower partition plate are arranged on the upper portion and the lower portion of an inner cavity of the device body correspondingly; the upper partition plate and the lower partitionplate sequentially separate the inner cavity of the device body into a crushing cavity, a mixing cavity and a discharging cavity from top to bottom; a plurality of fixed blades are evenly arranged onthe side wall of an inner cavity of the crushing cavity; a crushing motor is arranged in the center of the top end face of the device body; a rotating shaft is fixedly connected to a motor shaft of the crushing motor and rotatably connected to the device body through a first bearing; and a plurality of movable blades matched with the fixed blades are evenly arranged on the outer circle surface ofthe rotating shaft. The crushing motor drives the rotating shaft to rotate at a high speed, and thus drives the movable blades to rotate at a high speed to crush cleaned plastic, crushed particles meeting the hole diameter of a filter net directly fall into the mixing cavity through first communicating holes, thus the waste plastic is secondarily utilized, plastic pollution is lowered, the resource utilization rate is increased, the raw material cost is lowered, and production benefits are increased.

Description

technical field [0001] The invention relates to the technical field of secondary utilization of waste plastics, in particular to a plastic waste film extrusion device based on the secondary utilization technology of waste plastics. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. [0003] The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basica...
