Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a crusher for the purpose of rational crushing of various light materials such as polyethylene film, trays, packs, Styrofoam, paper and cardboard.

[0002]

2. Description of the Related Art Conventional crushers include a horizontal axis type crusher and a vertical axis type crusher, both of which are used regardless of whether they are light materials, molded products or lumps. These crushers were suitable for crushed objects having a high specific gravity with materials such as molded products or lumps.

[0003]

However, these crushers are unreasonable especially for crushing light materials such as polyethylene film, and since the upper part of the crushing chamber is opened and the hopper is attached, the start-up rotation is performed. Then, wind pressure was generated on the rotary blade, and the crushed object was pushed up in the hopper and slipped, and the biting was very bad. Such a defect cannot be solved even if the rotary blade is improved, and it is very dangerous if it is pushed in manually. As described above, in the conventional crusher, the thinner the crushed object is, the poorer the crushing efficiency is. was there.

[0004]

In order to solve the above-mentioned drawbacks, the present invention provides a crushing chamber A in the upper portion of a pedestal 24 in which a motor 21 is installed, and a plurality of crushing chambers A are provided from the rear portion to both inner sides of the large cylindrical chamber 3. In front of the crushing chamber A, a fixed blade 9 is provided, a screen 18 and a discharge port 19 are provided at the bottom, a conical cylindrical chamber 2 is formed at an intermediate portion, and a plurality of fixed blades 8 are provided at both inner sides. A small cylindrical chamber 1 is provided, a hopper 16 is provided on the upper winding side, and a rotatable shaft 4 is provided at the center of the crushing chamber A.
A plurality of large-sized main cutters 7 are provided from the rear portion of the shaft 4 by alternately interposing rings 10, a medium-sized main cutter 6 and an impeller 5 are provided adjacent to each other via a ring 10, and a pulley 20 is provided at one end of the shaft 4. Is provided, and the rotation of the motor 21 is transmitted to the shaft 4 via the belt 23 to the pulley 22 fixed to the motor 21.

[0005]

When the present invention is actually used, after the switch is turned on to start the motor 21, the material is put in by operating the handle of the damper 17 from the hopper 16. The introduced material is supplied by natural falling and is roughly crushed by an impeller installed in the small cylindrical chamber 1. The roughly crushed material is sent to the conical cylindrical chamber 2 and is moved in the axial direction while being rotated and disassembled by the engagement of the fixed blades 8 and the medium-sized main cutter 6 on both sides of the chamber, and then to the large cylindrical chamber 3. Sent. In the large cylindrical chamber 3, final finishing is performed by engaging the fixed blades 9 and the large main cutter 7 on both sides of the chamber. Finished products are sorted by the screen 18 and discharged through the discharge port 19 under pressure.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a crushing chamber A is provided above a pedestal 24 in which a motor 21 is installed, a plurality of fixed blades 9 are provided on both sides inside the large cylindrical chamber 3 from the rear, and a screen 18 is provided below.
And a discharge port 19, a conical cylindrical chamber 2 is formed in the middle portion, a plurality of fixed blades 8 are provided on both inner sides, a small cylindrical chamber 1 is provided in the front part of the crushing chamber A, and the upper part is wound. A hopper 16 is provided on the side, a rotatable shaft 4 is provided at the center of the crushing chamber A, and a plurality of large-sized main cutters 7 are provided from the rear portion of the shaft 4 by alternately interposing rings 10 and adjacent to each other. 10 through the middle-sized main cutter 6 and impeller 5
Is provided, a pulley 20 is provided at one end of the shaft 4, and the rotation of the motor 21 is transmitted to the shaft 4 via a belt 23 to a pulley 22 fixed to the motor 21. The crushing chamber A consists of a small cylindrical chamber 1 and a conical cylindrical chamber 2.
・ Three large cylindrical chambers 3 are arranged in order,
The upper half of each room can be opened and closed because maintenance work such as assembly and polishing is required. The conical cylindrical chamber 2 at the center plays a role of pumping air and the object to be crushed along the axis, and increases the pressure in the large cylindrical chamber 3 of the next chamber to enhance the crushing efficiency and the small chamber of the front chamber. A negative pressure acts on the cylindrical chamber 1 so as to suck the crushed object. The fixed blades 9 and 8 provided on both sides of the crushing chamber A are integrated with the large-sized main cutter 7, the medium-sized main cutter 6 and the impeller 5 incorporated in the shaft 4 to enhance their effect. Is configured.

[0007]

Since the present invention is configured as described above, it has the following effects. (A) Efficient crushing can be performed by structuring the crushing chamber so that the work of winding, pressure feeding, pressure crushing, and pressure discharging is performed in series. (B) The biting due to the natural fall was accelerated, and the crushing effect of pressure crushing and pressure discharge was enhanced. (C) Since the crushing chamber is a closed type and the crushed object is pressure-fed, it is possible to smoothly crush the ultra-thin object or the crushed object having a light specific gravity. (D) Since the required particle size can be freely set and can be pulverized, it can be applied to a wide range of applications such as recycling.
