Feeding device in waste plastic cutting and compacting extrusion granulator

Abstract

The invention discloses a feeding device in a waste plastic cutting and compacting extrusion granulator, comprising a compacting barrel with a cutting knife in the middle, a barrel is connected to the outer side of the compacting barrel and comprises a feeding section barrel and an extrusion section barrel, a feeding section screw is arranged in the feeding section barrel, an extrusion section screw is arranged in the extrusion section barrel, the compacting barrel and the feeding section barrel are mutually communicated, a connection part between the compacting barrel and the feeding section barrel is provided with a feeding port of the barrel, the diameter of the feeding section barrel is greater than that of the extrusion section barrel, the diameter of the feeding section screw is greater than that of the extrusion section screw, the feeding port is in a shape of a horn, and the heavy caliber end of the horn-shaped feeding port faces towards the compacting barrel. The invention provides the feeding device in the waste plastic cutting and compacting extrusion granulator, which is stable and sufficient in feeding, thereby ensuring that the waste plastic cutting and compacting extrusion granulator is high yield and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of the structure of a waste plastic cutting and compacting extrusion granulator, in particular to a feeding device in the waste plastic cutting and compacting extrusion granulator. Background technique [0002] In the process of cutting and compacting waste plastics, especially in the process of recycling and granulating waste PP, PE film and PP woven bags, the waste plastic materials to be granulated must be cut and compacted, and then transported to the granulator by centrifugal force. Granulation is realized after being in the machine. [0003] The structure of the feeding device in the currently used waste plastic cutting and compacting extrusion granulator is: a compacting cylinder with a cutting knife arranged in the middle, the outer side of the compacting cylinder is connected with an organic barrel, and the barrel includes The barrel of the feeding section and the barrel of the extrusion section, a...

AI Technical Summary

Problems solved by technology

The shortcoming of the currently used waste plastics cutting and compacting extrusion granulator is: since the diameter of the barrel of the feeding section is equal to the diameter of the barrel of the extrusion section, and the barrel of the feeding section and the barrel of the extrusion section are provided with The screw rod matched with its diameter, and because the feed port of the machine barrel is a square mouth, when the material enters the machine barrel from the compaction barrel, the feed is unstable and the feed is small, so the cutting and compacting of waste plastics is caused. Low output and high energy consumption
