A material feeding structure for an extruder used in the production of plastic steel profiles

Abstract

The invention discloses a novel feeding structure of an extruder for producing plastic steel profiles, and relates to the technical field of plastic steel profile production. The invention comprises a feeding hopper, an auxiliary material adding mechanism and a mixing cylinder. A mixing cylinder is nested above the inside of the feeding hopper, an auxiliary material adding mechanism is arranged directly above the center line of the feeding hopper, and a plurality of rows are arranged side by side on the bottom surface of the mixing cylinder. A material trough, and the discharge trough and the auxiliary material adding mechanism are arranged in parallel; a driving mechanism is arranged directly below the mixing cylinder; the driving mechanism includes a rectangular frame, a U-shaped frame and a sealing strip, and multiple sealing strips are arranged side by side. In the present invention, through the setting of auxiliary material adding mechanism, driving mechanism, driving wheel, driven wheel, belt and discharge trough and the mutual cooperation between components, the device can mix raw and auxiliary materials more evenly when in use, and this setting can realize The automatic addition of auxiliary materials reduces the labor force, and at the same time, the device does not need peripheral auxiliary equipment, which reduces the production cost and is easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of plastic-steel profile production, and in particular relates to a novel feeding structure of an extruder for plastic-steel profile production, which is mainly used for feeding the extruder for plastic-steel profile production. Background technique [0002] In the production process of plastic steel profiles, the function of the extruder is mainly to extrude the raw materials, and the feeding structure of the extruder is mainly to cooperate with the extruder to feed the material, so that the feeding of the extruder is more mechanized , to improve feeding efficiency, before feeding the extruder, the staff need to add the raw materials and auxiliary materials to the feeding structure for mixing and stirring, but the existing mixing method is only simple mixing through the stirring blade, the auxiliary materials and raw materials The overall mixing uniformity is poor, the quality of the finished product is une...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of feeding structure for extruders used in the production of plastic steel profiles. The quantitative and automatic addition of auxiliary materials can be realized through the setting of the auxiliary material adding mechanism, which reduces the labor force. The setting of the driving mechanism can drive the swing of the mixing cylinder , Through the transmission setting between the driving wheel and the driven wheel, the synchronous operation of feeding and mixing can be realized, which improves the uniformity of mixing, and the setting of the discharge groove on the mixing cylinder makes the whole feeding process without stirring equipment and vibration The cooperation of equipment effectively reduces the production cost and solves the problems of low mixing uniformity of raw and auxiliary materials, troublesome addition of auxiliary materials, high production cost and difficult maintenance in the existing extruder feeding structure.
