Abstract
The invention provides a plastic extruder which comprises a rack. A vibration exciter, a reduction gearbox and a power distributor are arranged at the upper end of the rack from left to right in sequence. The power distributor is connected with a feed cylinder. Screws are arranged in the feed cylinder. A vent hole is formed in the upper end of the feed cylinder. Heaters are arranged at the outer end of the feed cylinder. A neck ring mold is arranged at the right end of the feed cylinder. The plastic extruder has the advantages that the output of the three-screw plastic extruder is twice of that of a double-screw plastic extruder with the same specifications and the same power, and for production of the same number of products, the costs of manpower, sites and other items required by the three-screw plastic extruder are greatly reduced; no materials are piled up at the improved vent hole, the phenomena of outflowing and blocking of the materials can not occur due to the fact that the materials are almost sucked into a mixing area at the center of the screws, wherein the mixing area is equivalent to a melt pump and can not cause outflowing, so the plastic extruder can achieve high vacuum degree and improves quality of the products; and a pressure sensor is arranged on a pipeline of the vent hole, so the plastic extruder can achieve automated air exhausting.
Description
Technical field
The present invention relates to plastic hot processing machinery, refer more particularly to a kind of plastic extruder.
Background technology
Along with developing rapidly of plastic industry, the plastic extruder demand is also in continuous sharp increase, and the user is also improving constantly the product quality cost requirement simultaneously.In the plastic extruder production process, affect product quality thereby often can run into various impurity, this makes the impurities removal that how effectively solves in production process most important.
Present plastic extruder, its structure comprises: frame and be arranged on barrel, reductor and drive motors on frame, be provided with screw rod in barrel, one end of screw rod is connected with the output shaft of reduction box, in actual use, can't discharge because the moisture content that does not have steam vent, plastics to produce in heating process on barrel and low molecule gush thing, have influence on the quality of finished product.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of output is high, power consumption low and moisture content and low molecule that plastics can be produced gush the plastic extruder that thing discharges in heating process.
For addressing the above problem, the present invention adopts following technical scheme: a kind of plastic extruder, comprise frame, described frame upper end from left to right is disposed with vibrator, reduction box and power distribution device, described power distribution device is connected with barrel, is provided with screw rod in barrel, and described barrel upper end is provided with steam vent, described barrel outer end is provided with heater, and described barrel right-hand member is provided with a mouthful mould.
As preferred technical scheme, described screw rod is provided with three, and middle screw rod slightly is longer than the screw rod at two ends.
As preferred technical scheme, also be provided with measurement charging device on described power distribution device, described measurement charging device top arranges hopper, and an end is connected with the power distribution device, and the other end is connected with barrel.
As preferred technical scheme, described heater is provided with more than one, is ring heater, and heater two ends are bolted, and the centre is provided with cannelure, is provided with heating plate in described cannelure.
As preferred technical scheme, described steam vent lower end also is provided with pressure sensor.
As preferred technical scheme, to state frame inside and be provided with drive motors, described drive motors is the standard asynchronous motor.
As preferred technical scheme, described drive motors is connected with reduction box.
The beneficial effect of plastic extruder of the present invention is: 1, three screw rod plastic extruders, and its output specification, with the twice of power double-screw plastic extruder, to producing the product of equal number, the costs such as needed manpower, place reduce at double.2, the steam vent that changes machine is without any material accumulation, and more without phenomenons such as overflow, obstructions, its reason is the honey refining district that material nearly all is inhaled into the screw rod center, honey refining district just is equivalent to a Melt Pump, therefore can overflow, so this machine reaches very high vacuum, improved the quality of product.3, on the steam vent pipeline, pressure sensor is set, can realizes the exhaust automation.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of plastic extruder of the present invention;
Fig. 2 is the structural representation of heater for plastics extruder of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, a kind of plastic extruder of the present invention, comprise frame 11, described frame 11 upper ends from left to right are disposed with vibrator 1, reduction box 2 and power distribution device 3, described power distribution device 3 is connected with barrel 19, is provided with screw rod 9 in barrel 10, and described barrel 10 upper ends are provided with steam vent 7, described barrel 10 outer ends are provided with heater 6, and described barrel 10 right-hand members are provided with mouthful mould 8.
Wherein, described screw rod 9 is provided with three, and middle screw rod 9 slightly is longer than the screw rod 9 at two ends.
Also be provided with measurement charging device 4 on described power distribution device 3, described measurement charging device 4 tops arrange hopper 12, one ends and are connected with power distribution device 3, and the other end is connected with barrel 10.
Described heater 6 is provided with more than one, is ring heater, and heater 6 two ends connect by bolt 22, and the centre is provided with cannelure 23, is provided with heating plate in described cannelure 23.
Described steam vent 6 lower ends also are provided with pressure sensor.
Described drive motors 5 is connected with reduction box 2.
The beneficial effect of plastic extruder of the present invention is: 1, three screw rod plastic extruders, and its output specification, with the twice of power double-screw plastic extruder, to producing the product of equal number, the costs such as needed manpower, place reduce at double.2, the steam vent that changes machine is without any material accumulation, and more without phenomenons such as overflow, obstructions, its reason is the honey refining district that material nearly all is inhaled into the screw rod center, honey refining district just is equivalent to a Melt Pump, therefore can overflow, so this machine reaches very high vacuum, improved the quality of product.3, on the steam vent pipeline, pressure sensor is set, can realizes the exhaust automation.
The above be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
