Abstract

PURPOSE:To simultaneously perform grinding and compression by providing two screws different in a rotation direction in a main body case in parallel and mounting a cutting blade to a short shaft. CONSTITUTION:The material to be treated such as plastic charged in a main body case 2 from a supply port 3 is ground by a screw 5 and sent to a discharge part while compressed simultaneously and extruded to the outside through the opening part 4a of an extrusion mold 4 to be molded. The material subjected to extrusion molding is cut by a cutting blade 8 rotating outside an extrusion metal jig 4. By this method, said molded material can be cut into a pellet shape efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a two-wheeled screw crushing compressor that crushes, compresses, and cuts various plastics and other waste materials.

[Jubei technology] In general, methods for crushing various types of waste include crushing by impact, crushing by compressing, crushing by shearing, freezing and crushing using liquid nitrogen, and There is a method of crushing using a combination of methods.

However, with these conventional crushing methods, waste materials such as various plastics are simply crushed into a predetermined size, so the crushed plastic materials and other wastes are bulky, requiring a large amount of storage space and transportation. There was also a problem that the cost was high.

For this reason, in order to further reduce the volume of crushed plastic and other waste, it is generally compressed using a sterilizing rock.

Therefore, to process waste such as plastics, it is necessary to install a 2lIIM processing throat for crushing and compression, which is uneconomical due to high equipment and processing costs. [Problems to be Solved by the Invention] The present invention aims to eliminate the above-mentioned problems! It was created to solve the problems of crushing and compressing materials, and its purpose is to crush and compress at the same time. It is an object of the present invention to provide a two-wheeled screw crushing and compressor capable of further cutting a shaped material and transporting and disposing of waste materials such as plastics.

[Means for Solving the Problems 1] The two-wheel screw crushing compressor of the present invention is provided with a supply port on one side of the upper part of the main body case, and an extrusion mold installed on the other end, and a plurality of extrusion molds are installed in the extrusion mold. A triangular opening is opened, two screws with different rotational directions are installed in parallel inside the main body case, and a short shaft extending from the tip of the screw is made to protrude from the extrusion mold. and a cutting blade is attached to the tip jii, and the opening is triangular in shape, and the opening wall surface at the bottom is inclined inward toward the extrusion direction. It is something.

[Example 1] Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a base plate, on which a main body case 2 is installed. A supply port 3 for materials to be processed such as plastic waste is provided on one side of the main body case 2, and an extrusion port 3 is provided on the opposite side, that is, at the tip of the discharge side A mold 4 is attached.

Inside the main body case 1, two screws 5, 5 having different rotational directions are installed in parallel so as to mesh with each other. The supply side end of the screw 5 is connected to a drive shaft 6, and is rotated by a driving force m (not shown) such as an electric motor. %. A short shaft 7 extends from the distal end of the screw 5 on the discharge side. The short axis 7 passes through the extrusion mold 4,
A cutting blade 8 is attached to its tip. Therefore, as the screw 5 rotates, the cutting blade 8 rotates. On the other hand, the extrusion mold 4 has r
As is clear from FIG. 3, a total of six openings 4a, three each, are formed around the short axis 7. The openings 4a have an isosceles triangular shape with a short base, and their tops are aligned in each direction of rotation of the screw 5. Furthermore, the opening wall surface 4a' at the base of the isosceles triangle of the opening 4a is inclined inward toward the extrusion direction (arrow A), as shown in PIS 4, so that the extruded waste is compressed. I'm starting to receive it.

Note that the number of openings 4a is not limited to six as described above.

Since the device of this embodiment has the above structure,
The material to be processed, such as plastic, introduced into the main body case 2 from the supply port 3 goes up the screw 5 and is crushed and simultaneously sent toward the discharge side while being compressed, and is sent to the extrusion mold 4. The above opening 11fI! +4 a
through which it is extruded and shaped. The extruded and shaped workpiece is cut by the cutting blade 8 rotating outside the extrusion die 4 described above.

Note that by appropriately setting the extrusion speed and the number of cutting blades 8, the sharpness of the molded product to be cut off can be determined.

[Advantageous Effects of the Invention 1] Since the extrusion mold has a plurality of triangular openings, it is possible to perform high-density compression molding on various types of waste materials such as plastics.

2) Since the wall surface of the triangular base of the tlFI opening is inclined inward toward the extrusion direction, the object to be processed can be firmly compressed.

3) A short shaft is fixed to the tip of the screw, and the short shaft extends from the mold, and a cutting blade is attached to the tip, so the compressed workpiece can be efficiently cut into a vertical shape. can do.
