Driving device for PU tube extruder

Abstract

The invention discloses a driving device for a PU tube extruder. The driving device comprises an extruder body, a conveying device is fixedly mounted at the upper end of the extruder body, a protecting box is fixedly connected with the left part of the extruder body, a rotating device is fixedly mounted in the extruder body, a discharging opening is formed in the right end of the extruder body, aplurality of radiating grooves are formed in the middle of the front end of the extruder body, six bases are fixedly connected with the bottom end of the extruder body at equal intervals, a funnel isfixedly connected with the right end of conveying device, and a feeding tube is fixedly connected with the lower end of the funnel. According to the driving device of the PU tube extruder, by arranging the conveying device, a raw material can be controlled quantitatively to enter the extruder body, even conveying of the raw material is achieved accordingly, the product quality can be improved accordingly, and the product value is improved; and by rotating the rotating device, two screws rotate together accordingly, and the productivity and plasticity quality can be improved.

Description

technical field [0001] The invention relates to the technical field of plastic extruders, in particular to a transmission device for a PU pipe extruder. Background technique [0002] The extruder is one of the types of plastic machinery, which originated in the 18th century. According to the flow direction of the head and the angle between the centerline of the screw, the extruder can divide the head into a right-angle head and an oblique head. The extruder relies on the pressure and shear force generated by the rotation of the screw, which can fully plasticize and evenly mix the material, and form it through the die. The existing extruder is not uniform enough to discharge the material, which has a great impact on the product. The product levels are quite different, and the product quality and efficiency of single-screw operation are not good enough, so we propose a transmission device for PU pipe extruders.
