Description
Technical field
The present invention relates to the technical field of mechanical processing more particularly to the process equipments of PE wood plastic composites.
Background technology
PE wood plastic composites are a kind of advanced composite material (ACM)s for being surging forward in recent years both at home and abroad, are referred to using polyethylene, with
The plant fibers such as wood powder, rice husk, bamboo powder are mixed into new wood materials, and the composite material granular of mixture and granulation and preparation is
The raw material for producing plank or proximate matter, is mainly used for the industries such as building materials, furniture, logistics packaging.
The technological process of wood plastic composite is substantially as follows：Dry etc. the broken and crushing → former material of waste plastic, sawdust, tangerine
Processing → wood powder of material and mixed processing → granulation → extrusion → cooling and shaping → traction → fixed length cutting → finished product of plastics.Wood
The quality of plastic composite materials is largely related to exhaust effect because the small molecule volatile substance carried in wood powder and
Hydrone is easily that product brings defect, and in the prior art to the pre-treatment of material can not it is fully erased they, it may be considered that
The general effect that multistage exhaust promotes exhaust is set；After wood plastic composite leaves high temperature head should cooling and shaping immediately,
Otherwise it can deform under the effect of gravity, therefore its process equipment includes the upstream devices such as cooling body, haulage gear.
Invention content
It, can be while being mixed to material pair the invention is intended to provide a kind of process equipment of PE wood plastic composites
The processing that material is dried, is vented.
In order to achieve the above objectives, base case of the invention is as follows：The process equipment of PE wood plastic composites, including machine

There are piston rod, the free end of piston rod to be fixedly connected with slider box, the side far from piston rod is equipped with venthole, outlet in inflator
It is equipped with the valve being opened and closed by piston control in hole, pressure duct, the other end and vortex of pressure duct are also communicated on venthole
Pipe is connected to, and the hot gas outflux of vortex tube is connected to the hollow shaft.
The principle and advantage of this programme are：The hollow shaft rotation of this programme drives helical blade and blade rotation, can be right
Material is stirred, while material will be driven to move axially, and is stirred material while transporting boring to realize
The purpose mixed；
This programme is rotated using the rotation driven gear of hollow shaft, then transmits motion to work by toothed chain, sliding block etc.
Plug, piston move the gas in compressed gas cylinder, and band movable valve moves together after piston is moved to certain position, thus by outlet
Hole, which is opened, makes the compressed gas in inflator enter vortex tube, and the thermal current that compressed gas is formed after vortex tube passes through hollow shaft
It into helical blade, is blown out eventually by gas vent, to realize heating to material and wave the small molecule in material
The purpose that hair object and hydrone etc. are taken out of；
The screw conveyor of this programme selects hollow shaft, its intensity can be utilized high, light-weight and convenient for the characteristics such as coupling, right
Material is transmitted processing, while hollow shaft also constitutes the flow channel of thermal current, and thermal current is directed in material；
The vortex tube of this programme also will produce cold air, can be used for providing energy for the refrigerating plant of composite material extruding machine
Amount.
Further, the valve includes the valve plate and control handle of connection fastened to each other, and sliding slot, valve plate sliding are equipped in inflator
It is connected in sliding slot, control handle is fixedly connected on valve plate, control handle is located in inflator, fixed between the valve plate and inflator to connect
It is connected to compression spring.
This programme is simple in structure, easy to process, and when can realize that gas pressure intensity is increased to a certain amount of in inflator, and valve is
The purpose that can be opened by piston.
Further, the circumferential surface of the valve plate is equipped with rubber layer.
The air-tightness of inflator can be ensured in the circumferential surface setting rubber layer of valve plate, be advantageously implemented in inflator and formed high pressure gas
Demand.
Further, the gas vent is equipped with the filter device for preventing material from entering helical blade.
Because helical blade can drive material to axially move together during rotating, one can be generated to material
Axial thrust, helical blade, which mutually squeezes to may result in material and from gas vent enter in helical blade with material, to be caused to be vented
Hole plug, setting filter device can be such that the hot gas in helical blade is blown into material, while be avoided that material is caught in gas vent again
Cause to block.
Further, it is fixed with thrust bearing between the hollow shaft and hopper.
Because hollow shaft is rotatablely connected with hopper, damage is caused to reduce phase mutual friction, therefore bearing is set and alleviates hollow shaft and material
Phase mutual friction between slot；Meanwhile helical blade drives material when axially moving, material will produce the reaction of an axial direction
Power to avoid hollow shaft from axially moving relative to hopper, therefore selects thrust bearing to bear axial load.
Further, the free end of the blade is equipped with sawtooth.
When blade is rotated with hollow shaft, material can be played the role of stirring, setting sawtooth can avoid material caking etc.
The problem of causing blade to be stuck can not rotate.
Further, the hopper selects cylinder type.
It will be at material scraper the case where hopper when hopper selects cylinder type to be avoided that blade stirring.
