Abstract
A forced feeding device for a PVC powder on an extrusion film blowing machine relates to the technical field of film blowing machine. The device includes a hopper connected to the film blowing machine; a spiral feeder is arranged on the central position of the hopper; the spiral feeder is connected with a servo motor; the servo motor drives the spiral feeder to rotate and work, so as to guarantee stable feeding of the hopper. The invention has the advantages of simple structure and novel design, and can well control feeding of the feed hopper, ensure stable supply and ensure the consistency of the products of a film blowing machine.
Description
Technical field
The present invention relates to inflation film manufacturing machine technical field, be specifically related to a kind of PVC powder at the forced-feeding device of extruding on inflation film manufacturing machine.
Background technology
PVC raw material is being mainly that state with powder exists in the market, although also there is the raw material of particle, its prerequisite is also that the polyvinyl chloride resin powder granulation by powdery forms.So in extrusion process because polyvinyl chloride resin is that powdery often there will be " bridge formation " phenomenon in extrusion, thereby few when many while causing feed, the pressure transient of die head, the generation of the phenomenon such as discharging is inhomogeneous.The difficult quality of product is controlled.
Summary of the invention
It is a kind of simple in structure that technical problem to be solved by this invention is to provide, and improves the PVC powder of feed stability at the forced-feeding device of extruding on inflation film manufacturing machine.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of PVC powder is at the forced-feeding device of extruding on inflation film manufacturing machine, comprise the hopper being connected on inflation film manufacturing machine, middle position at described hopper is provided with a helical form feeder, described helical form feeder is connected with servomotor, by servomotor, drive helical form feeder rotary work, assurance hopper can be stablized charging.
Described helical form feeder is a spiral feed worm.
Described spiral feed worm longitudinally arranges, and by it, rotates longitudinally, controls the stable feed that its rotary speed realizes powdery polyvinyl chloride resin powder.
The invention has the beneficial effects as follows: the present invention is simple in structure, modern design, can be good at controlling the charging material of hopper, guarantees stable material-supplying, guarantees the uniformity of inflation film manufacturing machine output product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of PVC powder is at the forced-feeding device of extruding on inflation film manufacturing machine, comprise the hopper 2 being connected on inflation film manufacturing machine 1, middle position at hopper 2 is provided with a helical form feeder 3, helical form feeder 3 is connected with servomotor 4, by servomotor 4, drive helical form feeder 3 rotary works, assurance hopper can be stablized charging.Helical form feeder 3 is a spiral feed worm, and spiral feed worm longitudinally arranges, and by it, rotates longitudinally, controls the stable feed that its rotary speed realizes powdery polyvinyl chloride resin powder.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
