Abstract
The utility model discloses a conical metering compression feeding machine which comprises a conical hopper, a screw extruder, a speed reduction motor and a stirring screw rod. The conical metering compression feeding machine is characterized in that the conical hopper is connected with a feeding hole of the screw extruder; the speed reduction motor is arranged above the conical hopper and is connected with the stirring screw rod through a thrust bearing; a stirring cutter is arranged at the upper part of the stirring screw rod; and a conical hopper feeding hole is close to the circumferential edge of the conical hopper. By adopting the conical metering compression feeding machine, a filled wood powder material can be uniformly stirred and mixed with substrate plastic and the phenomenon of bridging of the materials is also avoided during the mixing process; after the mixed material enters the hopper behind a cylindrical section, the fluffy mixed material can be compressed through the rotating stirring screw rod with varying pitch and then can be fed to the extruder quantitatively to realize stable production.
Description
Technical field
The utility model 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, Wood flour filled PVC powder and PE wood molding powder machine) feeding extrusion forming wood-plastic goods, the metering of taper specifically compression feeding machine.
Background technology
Wood plastic composite be a kind of be the composite that basic material and plastics are made by timber or cellulose.Be powder because the wood fibre adding is most of; be difficult for extruder screw feeding and wood powder structure is fluffy; 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.But " bridge formation " and " embracing screw rod " this phenomenon is just more obvious while containing more moisture in wood powder, 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 in the utility model 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 utility model 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, extrude feeding with " compression " weight feed extruder that meets fluffy radwood.
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 utility model, 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.Enter in the hopper after cylindrical section with mixed material, can realize after the compression of fluffy compound through the Stirring screw rod of varying pitch, measuring fixed amount feeding is realized steady production to extruder.
Brief description of the drawings

Detailed description of the invention
How further illustrate the utility model below in conjunction with accompanying drawing 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 to rotate, 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 " in the time rotating by cutting apart in design.Material enters along the agitating screw of vertical rotary in the screw rod of varying pitch helical pitch, and the compression that can carry out to a certain degree fluffy material quantitatively flows to extruder afterwards.Can produce certain kick at the agitating screw of the total rotation of this process 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 bring.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 utility model 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.
