Description
Technical field
The present invention relates to plastic extruder, particularly a kind of portable minisize plastic extruder.
Background technology
Usually general plastic extruder is to be grouped into by motor, reductor, screw rod, barrel, heater and electric control part, screw diameter is between 20mm-200mm, and mostly be to be fixed on and process on the place and produce, the power supply of use is that what to be added in 380 volts the alternating current, hopper is granular raw material.But some situation need be carried out site operation, and this is incompetent for the existing plastic extruder as suitability for industrialized production equipment that those are fixed on the place.Therefore, need a kind of plastic extruder that can use at the construction field (site).
Summary of the invention
Purpose of the present invention is exactly to provide a kind of micro plastic extruder in light weight, easy to carry for site operation.
For achieving the above object, the principle that the present invention extrudes according to single screw rod has designed the portable minisize plastic extruder of a kind of structure and service condition uniqueness, it comprises: a Power Drive Unit, a support that is connected with Power Drive Unit, one is passed through the power transmission shaft that a minor axis is connected with the Power Drive Unit output shaft in support, power transmission shaft overcoating bar auger conveyor, a rotary-cut cutter and a screw rod, the rotary-cut cutter is installed in the section start of screw rod feeding section and together rotates with screw rod, there is the homogenizing zone that has installed pin additional the screw rod end, the input of screw rod links to each other with the other end of power transmission shaft, a barrel, its front end connects the transition body, the rear end connects support, heating collar is equipped with in the outside, and the transition body that head and barrel are linked together has been installed on it and is used for the head that temperature controlled thermocouple and can 360 degree rotate.
Extruder of the present invention uses 220 volts of AC powers, and the raw material of use is the round plastic bar of 4mm-5mm.This machine can be changed different heads and be applicable to different purposes, and multiple tube capper head, bar shaped head and circular head are arranged.This machine uses 220 volts of AC powers, is specially adapted to not have use under the condition of 380 volts of electrical source of power.
Extruder of the present invention can be applied to the welding and the filling of plastic products under many specified conditions.For example behind the disconnected pipe of job site steel skeleton plastic clad pipe, steel wire is exposed must to wrap up steel wire with the plastics with material, in order to avoid medium is revealed and the corrosion steel wire, the plastics that at this moment available extruder of the present invention is extruded fusion carry out on-the-spot sealing operation.Extruder of the present invention also can carry out the work such as welding of plastic plate, sheet material at the construction field (site).
Structure of the present invention will be described in detail in conjunction with following accompanying drawing.
