Abstract

PURPOSE:To save labor in monitoring and cleaning and to remarkably improve the working efficiency of waste crushing work by inserting two shafts of different revolutions in work gears engaged with each other, put one on top of the other and alternatively rotating the work gears in connection with the different revolutions of the two shafts to make the simultaneous treatment of pressure crushing and cutting. CONSTITUTION:In a waste crusher 1, wastes are passed through the engaged part between work gears 5, 6 engaged with each other to make simultaneous treatment of pressure crushing and cutting. Two parallel A, B shafts 3, 4 rotating at different revolutions are inserted into plural sets of work gears 5, 6 of the same diameter which are engaged with each other in a set of two, put one on top of the other. The work gears of each set 5a, 6a-5f, 6f are alternatively rotated in connection with different revolutions of the A shaft 3 and the B shaft 4 to perform the simultaneous treatment of compression crushing and cutting of the wastes. Consequently, the wastes are given compression crushing by the engagement of the teeth of each set and also torn off, and the difference in velocity between the adjacent teeth causes the wastes to be cut and helps crush them. Further the crushed materials tending to stick on the root of the teeth are repelled by lateral force on cutting to prevent them from clogging the equipment.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste crushing apparatus capable of simultaneously performing crushing and cutting. More specifically, a plurality of sets of machined gears, which are fitted in a stack, are alternately rotated at different rotational speeds. The present invention relates to a waste crushing device having a new structure that rotates as described above.

[0002]

2. Description of the Related Art In a conventional waste crushing apparatus, waste to be crushed, which is put in from above, is crushed through a gap between two machining gears that rotate in mesh with each other and is discharged from below. Further, the conventional processed gears are those in which a plurality of thick single-width gears and a plurality of thin-width gears are stacked and integrally formed, but two facing processed gears mesh with each other and rotate at the same speed, The waste is compressed and crushed during meshing.

[0003]

However, in the conventional waste crushing device, the waste crushed during the meshing of the processed gears is crushed by compression, so that it is likely to be pressed and clogged in the valleys of the teeth. Have challenges. Further, if the waste is clogged in the valleys of the teeth, it becomes an overload, which causes work failure and damage to the crushing device. for that reason,
During the work, it was necessary to constantly monitor the adhesion state of the waste in the valleys of the teeth and clean it, which reduced the efficiency of the crushing work.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and in the waste crushing apparatus of the present invention, a plurality of sets of machined gears are alternately rotated in different directions. Rotate by, the waste of the crushed object is compressed and crushed by the meshing of the teeth of each set and cut off, and it is also cut by the speed difference between the teeth of the adjacent set to assist the crushing. With the lateral force of, the crushed material that tends to adhere to the valleys of the teeth is repelled, and the crushed material is prevented from clogging. Further, in another waste crushing apparatus of the present invention, the A-axis on the driving side and the B-axis on the driven side are separated from each other with respect to the overload that may occur during crushing and cutting. It is intended to ensure the safety of.

That is, the waste crushing apparatus of the present invention is a waste crushing apparatus in which waste material to be crushed is passed between meshing meshing gears and crushed by simultaneous crushing and cutting. , A2 and B parallel shafts rotating at different rotation speeds are fitted with a set of two meshing gears, and the machining gears of each group are alternately rotated differently. It is characterized by a structure that enables simultaneous processing of crushing and cutting of waste materials by engaging with. Further, in the shredding device of the present invention, the motive side A shaft is pivotally supported by the A bearing body fixed to the machine body, and the driven side B shaft is slidable.
It is characterized in that it is supported by the bearing body and the B bearing body is biased toward the A bearing body so that the meshing of the machined gears fitted into the A and B axes can be held. Further, the B bearing body is characterized in that it is biased by a spring so that the biasing force can be adjusted. Examples of wastes to be crushed applied by the device of the present invention include empty cans, empty bottles, garbage, scraps of dismantled buildings, recovered newspapers and recycled magazines (recycled paper) for the production of recycled paper, and the like.

In particular, waste paper such as recovered newspapers and magazines, which are used as raw materials for producing recycled paper, are pulped by mechanical and chemical treatments in the recycling process. However, the fine paper obtained by being hung in a shredder has sharply cut edges, and the fibers become short, so there is a problem that the fiber length suitable for papermaking cannot be retained even when pulped. It was However, according to the device of the present invention, since the waste paper is not cut into small pieces but is torn apart from each other, fibers are extended at the edge of the paper processed by the device of the present invention. It will remain. Therefore, it is preferable to use the device of the present invention in the mechanical treatment process of waste paper for producing recycled paper.

The rear end is in contact with the front surface of the adjusting screw 11. The spring 13 is biased by the adjusting screw 11 and presses the back surface 10 a of the B bearing body 10 via the head of the push pin 12. B bearing body 1
0 is in a state of being urged toward the A bearing body 9 (direction of arrow C), and abuts on the contact portion 2C of the machine body 2 to be locked. At this time, the machined gear 5 fitted on the A shaft 3 and the machined gear 6 fitted on the B shaft 4 are held in a properly meshed state. The biasing force of the spring 13 is adjusted by moving the adjusting screw 11 back and forth.

A small gear 14 is fixed to the rear portion of the A shaft 3, and a large gear 15 meshing with the small gear 14 is fixed to the rear portion of the B shaft 4. A driving sprocket 16 is fixed to the rearmost portion of the A shaft 3, and a drive sprocket 1 is attached to the tip of a geared motor 18 installed outside the machine body 2.
7 is fixed, and a drive chain is hung between the two. Therefore, the rotation of the geared motor 18 is decelerated from the drive sprocket 17 through the driving sprocket 16 to rotate the A shaft 3 on the driving side in the A direction. Furthermore,
The rotation of the A shaft 3 is decelerated from the small gear 14 through the large gear 15 to rotate the driven B shaft 4 in the B direction. That is, A
Since the shaft 3 rotates fast and the B shaft 4 rotates slowly, each set of 5a, 6a, 5c, 6c and 5e, 6e that rotates together with the A shaft 3 is fast and rotates 5b and 6b together with the B shaft 4. Each set of 5d, 6d and 5f, 6f rotates slowly causing the six sets of machine gears to alternately engage different rotations of the fast A-axis 3 and slow B-axis 4.

Thus, the waste of the crushed material, which is input from the input port 19 on the upper side of the machine body 2, is crushed between the working gears 5 and 6 of each set which rotate in mesh with each other, and alternately rotate differently. Rotate at, for example, 5a, 6a and 5
Cutting between adjacent sets of machined gears, such as sets b, 6b. This cutting aids crushing, and also prevents lateral forces during cutting from clogging the crushed material into the valleys of the teeth. Further, if overload occurs during crush cutting, the six machining gears 6 on the B shaft 4 side move away in the D direction together with the B bearing body 10 against the urging force of the spring 13 in the C direction. The mesh between the gears 5 and 6 is disengaged. At that time, the push pin 12 is also D
It moves in the direction and is detected by the sensor 21, and the geared motor 18 is stopped to ensure the safety of the machine.

[0012]
