Abstract
The invention discloses a tapered metering compression feeder which comprises a tapered hopper, a screw extruder, a speed reducing motor and a mixing screw rod, and is characterized in that the tapered hopper is connected with a feeding hole of the screw extruder; the speed reducing motor is arranged above the tapered hopper and is connected with the mixing screw rod by a thrust bearing; a mixing cutter is arranged at the upper part of the mixing screw rod; the tapered hopper has a tapered hopper feeding hole at the position close to the edge of the circumference. After the tapered metering compression feeder is used, the filled wood powder and substrate plastic can be evenly mixed, and the phenomenon of 'bridging' of the material can be prevented in the mixing process. The mixture enters the hopper behind a cylindrical section, the fluffy mixture can be compressed by the mixing screw rod rotating with varying pitch, and the extruder is fed in a way of quantitative metering, so that stable production can be realized.
Description
Technical field
The present invention relates to the feeding of the materials such as fluffy material, powdery and discrete particles, that a kind of being exclusively used in needs continuous and quantitative to supply with fluffy material, powdery or discrete particles to block the charging system to extruder equipment, be specially adapted to fluffy material, powdery or discrete particles material (as with must shape flax PVC powder, the wooden molding powder machine of Wood flour filled PVC powder and PE) feeding extrusion forming wood-plastic goods, the metering of taper specifically compression feeding machine.
Background technology
Wood plastic composite be a kind of by timber or cellulose, be the composite that basic material and plastics are made.Because the wood fibre adding is most of, it is powder; and wood powder structure is fluffy, be difficult for extruder screw feeding; between plastic substrate and inserts, can not form desirable mixture uniformity simultaneously and join in extruder, so usually there will be " bridge formation " and " embracing screw rod " phenomenon in reinforced process.And at present wood is moulded the feeding manner of extruding and is had the hopper of employing weight feeding or hunger-type level list screw rod metering feeding or twin-screw metering feeding naturally.Yet while containing more moisture in wood powder, " bridge formation " and " embracing screw rod " this phenomenon is just more obvious, causes extrude unstable, especially cannot meet the requirement of large output extruder production heavy in section goods.
Summary of the invention
The problems of the prior art to be solved by this invention are: in prior art, wood is moulded in raw materials process because of the fluffy usually appearance " bridge formation " of wood powder structure and " embracing screw rod " phenomenon, and cause extrude unstable, especially cannot meet the requirement of large output extruder production heavy in section goods.
The present invention is for solving the aforementioned problems in the prior, the technical scheme adopting is: a kind of vertical taper hopper+cylinder straight section combining structure is provided and is equipped with the stirring conveying screw rod that VFC drives, to meet " compression " weight feed extruder of fluffy radwood, extrude feeding.
Taper metering compression feeding machine, comprising: broach hopper, screw extruder, reducing motor, agitating screw, is characterized in that: described broach hopper and the spout of screw extruder interconnect; The top that described reducing motor is placed in broach hopper is connected with agitating screw by thrust bearing; The top of described agitating screw is provided with stirring rounding knife; Described broach hopper is provided with broach hopper charge door near circumferential edges place.
Taper metering compression feeding machine of the present invention, can be uniformly mixed " bridge formation " phenomenon generation that also prevents from expecting material in this process uniformly to the wood powder material of filling and matrix plastic.With mixed material, enter in the hopper after cylindrical section, through the Stirring screw rod of varying pitch, can realize after the compression of fluffy compound, measuring fixed amount feeding is realized steady production to extruder.
Accompanying drawing explanation
Fig. 1 is the structural representation of taper metering compression feeding machine
Fig. 2 is the top view of taper metering compression feeding machine
The specific embodiment
How below in conjunction with accompanying drawing, further illustrate the present invention realizes.
As shown in Figure 1, taper metering compression feeding machine, comprising: broach hopper 2, screw extruder 7, reducing motor 3, agitating screw 4, is characterized in that: described broach hopper 2 interconnects with the spout of screw extruder 7; The top that described reducing motor 3 is placed in broach hopper 2 is connected with agitating screw 4 by thrust bearing 5; The top of described agitating screw 4 is provided with stirs rounding knife 6; Described broach hopper 2 is provided with broach hopper charge door 1 near circumferential edges place.
Fluffy mixed material joins broach hopper from broach hopper charge door 1, and material fills up whole broach hopper 2 need to enough intensity wear resistant corrosion resistants, and the tapering of hopper is less than the angle of repose that is sent material by Sheng simultaneously.Connect lower startup reducing motor 3, reducing motor 3 need to have enough moments of torsion and speed controlled, drive agitating screw 4 rotations, the agitating screw 4 of rotation is made for etch-proof stainless steel material, it need to, with rounding knife, can stir and prevent the appearance of " bridge formation " when rotating by cutting apart in design.Material enters in the screw rod of varying pitch helical pitch along the agitating screw of vertical rotary, and the compression that can carry out to a certain degree fluffy material quantitatively flows to extruder afterwards.At the agitating screw of the total rotation of this process, can produce certain kick in to the compression process of material and pass to thrust bearing 5, thrust bearing 5 absorbs the kick that has transformed rotary screw compression and brought.By regulating the speed of reductor rotating speed, can realize the change to feed system supply mode, realizing extruder feed is to force or the quantitatively switching of hunger-type, required to maintain the steady production of continuous running extruder of system like this.
The present invention and prior art contrast, use taper metering compression feeding machine structure, by regulating the speed of reductor rotating speed, can realize the mode that feed system is supplied with changes, realizing extruder feed is the feature of the switching of pressure or quantitative hunger-type, no longer includes the phenomenon because of " bridge formation " and " embracing screw rod " not blanking.
