Abstract
The utility model discloses a PVC-U energy-saving extruding and quantitative feeding device for pipes. The device comprises a hopper which is connected with an extruder sol screw feed cylinder and is characterized in that a stirring mechanism used for turning materials in the hopper is arranged in the hopper. The stirring mechanism is composed of a transmission shaft, stirring blades and a drive motor, the transmission shaft is horizontally arranged along the hopper, and the stirring blades are evenly arranged on the transmission shaft. According to the device, a viscous phenomenon of the materials in the hopper is controlled effectively, original problems that product quality and product yield are low caused by uneven blanking are changed, and particularly the control on the wall thickness of pipes is improved apparently.
Description
Technical field
The invention belongs to pipe production technical field in the plastic conduit production industry, relate in particular to a kind of PVC-U pipe extruder feeding device.
Background technology:
PVC-U tubing (hard polyvinyl chloride pipe) is that China introduces external a kind of plastic pipe the earliest, is mainly used in fields such as draining, blowdown, feedwater and electric power, communication cable protecting pipe.The prescription of PVC-U tubing is the production that feeds intake again after auxiliary material such as polyvinyl chloride resin powder (powder) and calcium carbonate (powder) and modifier, color masterbatch mix through high temperature and high speed.The ratio of calcium carbonate is very high in the PVC-U mixture of raw materials; And the calcium carbonate molecule is the spindle crystalline structure, and contains other material composition of viscous in the PVC-U composition of raw materials, after particularly stirring through high-speed mixing in process of production; Blanking is inhomogeneous, causes the putty phenomenon easily.
Summary of the invention
The present invention provides a kind of PVC-U pipe extruder feeding device of new structure for fear of the weak point that prior art exists, and occurs the not smooth technology difficult problem of blanking when the blanking to solve in the PVC-U tubing extrusion powder formulation material.
Technical solution problem of the present invention adopts following scheme:
PVC-U tubing is extruded energy-conservation, dosing device, comprises the hopper that is connected with extruder colloidal sol screw cylinder, it is characterized in that: be provided with the rabbling mechanism that is used for material in the Turnover bunker in the said hopper.
Design feature of the present invention also is: said rabbling mechanism is made up of power transmission shaft, the stirring vane and the drive motors that are fixedly installed on the power transmission shaft, and said power transmission shaft is horizontally disposed with in hopper.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, often cause the bonding of raw material and auxiliary material, auxiliary agent in the hopper of existing feeding device, and the present invention has set up rabbling mechanism in hopper, because the stable uniform rotation of blade is stirred; Effectively controlled the bonding of raw material and assistant agent, auxiliary agent; Guaranteed that raw material even feeding in the blanking process can not cause because feed opening stops up to make extruder lack the phenomenon of expecting, thereby improve product quality to extruder; Reduce product rejection rate, practiced thrift raw material greatly.
2, the present invention has effectively controlled raw material " viscous " phenomenon in hopper, has changed original owing to obviously promoted in the control of the uneven product quality that is caused of blanking, the problem of decrease in yield, particularly tube wall thickness.The less investment of the present invention technology, take effect obviously and fast, to PVC-U pipe material product quality promote, yield rate promotes the key effect of having played.
Description of drawings
Fig. 1, Fig. 2 are this use new structure sketch mapes.
Label among the figure: 1 extruder colloidal sol screw cylinder, 2 hoppers, 3 power transmission shafts, 4 stirring vanes.
The present invention is further specified through the specific embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in the figure, feeding device comprises the hopper 2 that is connected with extruder colloidal sol screw cylinder 1; Be provided with the rabbling mechanism that is used for material in the Turnover bunker in the hopper 2; Rabbling mechanism is made up of power transmission shaft 3, stirring vane 4 and drive motors, and power transmission shaft 3 is the transverse horizontal setting in hopper, and it circumferentially evenly is provided with multi-disc stirring vane 4 in the power transmission shaft upper edge; Drive motors drives power transmission shaft and rotates under driving through transmission decelerating device; Along with the rotation of power transmission shaft, stirring vane is uniform motion in hopper, and the PVC powder material in the hopper is through the active force of blade; Do the action of quota feeding in time at per unit, continue to carry out the quota feeding to the double screw extruder charging aperture uniformly.
