Description

Double-feeding extruder

Technical Field

The application relates to the field of extruders, in particular to a double-feeding extruder.

Background

In the prior art, waste plastics are often evenly cut into small particles through a granulating machine, auxiliary fillers such as color master batches and a smell removing agent are added to be evenly mixed, then the mixture is extruded and molded from an extruder to be deeply processed, the waste plastics and the auxiliary fillers are placed in a barrel by the existing extruder to be cut and mixed, the phenomena of uneven mixing and the like often occur, and the product quality is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a two feeding extruders to overcome not enough among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme:

the embodiment of the application discloses two feeding extruders, which comprises a frame, be equipped with the extruder motor, shaft coupling, extruder speed reducer and the screw rod that connect gradually in the frame, be connected with the major ingredient feedwell on the screw rod, be equipped with the rotation axis in the major ingredient feedwell, be equipped with the blade on the rotation axis, be equipped with the feeding motor through belt connection rotation axis in the frame, its characterized in that: the auxiliary material feeding barrel is connected with the screw through a feeding machine, and a feeding speed reducer is connected to the feeding machine.

Preferably, in a double feed extruder as described above, the feeder is a single screw feeder.

Preferably, in a twin feed extruder of the kind described above, the blades are arcuate.

Compared with the prior art, the utility model has the advantages of:

this two feeding extruders are connected with the extruder screw rod through two solitary feed mechanism of major ingredient and auxiliary material, directly pour into major ingredient and auxiliary material in the extruder screw rod, the major ingredient passes through centrifugal force and gets into the extruder, the auxiliary material gets into the extruder through single screw rod feeding machine, the speed that major ingredient and auxiliary material got into the extruder can be regulated and control respectively through the speed reducer of control rotating electrical machines and feeding machine, thereby can more accurate control major ingredient and auxiliary material mix in the extruder screw rod, it is more accurate even and high-efficient, improve product quality.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present application, and it is obvious for those skilled in the art to obtain other drawings based on the drawings without creative efforts.
