Abstract
The utility model relates to a plastics double screw extruder, including drive arrangement, be connected with transmission on drive arrangement one side, be connected with extrusion device on transmission one side, be equipped with the feeder hopper on the transmission, the inside output shaft that is equipped with parallel arrangement of extrusion device, be equipped with helical blade on each output shaft, the extrusion device upper end is equipped with sealed lid, sealed lid is connected with the air treatment case through the blast pipe, it is crescent that each output shaft is close to discharge gate one end diameter from feed inlet one end. The utility model discloses a set up sealed lid, air treatment case, the healthy of workman is avoided influencing by the gas of extrusion device production like this after the air treatment case is handled, through the output shaft that sets up the reducing, plastics improve the plastify effect of plastics in that to extrude in -process extruded pressure crescent like this, and the practicality is good.
Description
Technical field
The utility model relates to plastics arts, particularly relates to a kind of plastics double screw extruder.
Background technology
Plastics are raw material based on synthetic resin or natural resin, adds (or not adding) various plastic additive, reinforcing material and filler, and under uniform temperature, pressure, the type of making is moulded in processing or crosslinking curing is shaping, the solid material obtained or goods.Plastics refer to resin (or using monomer direct polymerization in process) as main component, with additives such as plasticizer, filler, lubricant, colouring agents for auxiliary element, the material of energy flowing forming in process, be the macromolecular compound of synthesis, freely can change body styles.Utilize the material that raw material monomer is polymerized with synthesis or condensation reaction, be made up of additives such as synthetic resin and filler, plasticizer, stabilizing agent, lubricant, colorants, its main component is synthetic resin.
In the production process of film, be that powder is loaded in hello barrel, pass through extruder for shaping.But in the process extruded, can produce some chemical gas affects the healthy of workman, the output shaft of existing extruder is generally isometrical simultaneously, causes plastics plasticizing effect poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of plastics double screw extruder.
The utility model is achieved through the following technical solutions:
A kind of plastics double screw extruder, comprise drive unit, described drive unit side is connected with transmission device, described transmission device side is connected with extrusion device, transmission device upper end is provided with feed hopper, described extrusion device inside is provided with the output shaft be arranged in parallel, each output shaft described is provided with helical blade, described extrusion device upper end is provided with seal cover, described seal cover is connected with air-treatment case by blast pipe, and each output shaft described increases gradually from charging aperture one end near discharging opening one end diameter.
As optimal technical scheme of the present utility model, between described seal cover and extrusion device, be provided with sealing gasket.
As optimal technical scheme of the present utility model, for removably connecting between described air-treatment case and extrusion device.
As optimal technical scheme of the present utility model, the most outside diameter of described output shaft is the twice of smallest end diameter.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging seal cover, air-treatment case, and the gas that such extrusion device produces is avoided affecting the healthy of workman after the process of air-treatment case; By arranging the output shaft of reducing, the pressure that such plastics extrude in extrusion increases gradually, and improve the plasticizing effect of plastics, practicality is good.
