Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting device, and particularly to a cutting crusher equipped with a disk having a plurality of blades arranged in parallel in the circumferential direction.

[Prior Art] Conventionally, as a technology in this type of field, the one shown in FIG. 10 is known. The outline will be explained below based on the figure.

In the drawing, 1 represents the casing,
Two parallel shafts 3 and 4 are supported by the casing 1 via bearings 2, . . . .
In addition, the casing 1 of each of these shafts 3 and 4
The part extending inward is provided with blades 5a in the circumferential direction.
(Fig. 11), a plurality of disks 5 arranged in parallel,
Collars 6 having a smaller diameter than the disks 5 are alternately externally fitted and supported. In this case, the thickness of the disk 5 and the thickness of the collar 6 are made equal, and the other disk 5 is positioned between the disks 5 of each shaft. Further, the sum of the inner diameter of the disk 5 and the inner diameter of the collar 6 is twice the distance between the shafts 3 and 4, and as a result, the blade 5a of the disk 5
The cutting edge of the collar 6 and the outer circumferential surface of the collar 6 come into contact with each other.

Further, at one end of the shafts 3 and 4 protruding outward from the casing 1, spur gears 7, which mesh with each other, are provided.
8 are attached to each. This allows the shafts 3 and 4 to rotate in opposite directions.

Furthermore, a motor 10 is connected to the other end of the shaft 3 protruding outward from the casing 1 via a speed reduction mechanism 9.
are connected.

Incidentally, comb-shaped fixed blades 12, 12 are provided outside the disk 5 and the collar 6 in the casing 1 so as to be in contact with the disk 5 and the collar 6.

Next, the disk 5 of the conventional cutting type crusher constructed as described above will be explained in more detail.

FIG. 11 shows a schematic configuration of the disk 5. As shown in FIG. To explain the outline based on FIG. 11, a plurality of blades 5a are arranged in parallel on the outer periphery of the disk 5. This blade 5
a is formed so that the cutting edge surface 14a is flush with the radial surface of the disk 5, and on the other hand, the rear back surface (conveying surface) 1 which defines the blade 5a together with the cutting edge surface 14a.
4b converges on the proximal end of the cutting surface 14a of the adjacent blade 5a.

Next, the operation of this cutting type crusher will be explained.

When the motor 10 is driven, its driving force is transmitted to the shaft 3 through the deceleration mechanism 9,
Furthermore, it is transmitted to the shaft 4 through the spur gear teeth 7 and 8. In this way, the shafts 3 and 4 are rotated. In this case, the rotation directions of the shafts 3 and 4 are opposite to each other, and are the directions in which the input material is drawn in (see the arrows in FIG. 11 and FIG. 12).

Here, when the encapsulating material is put into the casing 1,
The input material is loaded on the rear surface 14b of the blade 5a, and is drawn between the disks 5 and 5 between the shafts 3 and 4, and is then drawn between the disks 5 and 5 between the shafts 3 and 4, and is transferred between the blade 5a that continues to the rear surface 14b and the partner blade 5a. and cut into a predetermined size. The cut products (cutting powder) are then discharged downward through the space between the opposing disk 5 and collar 6.

[Problems to be Solved by the Invention] However, in the conventional cutting type crusher, as shown in FIG.
Since the cutting surfaces 5a of the blades 5a were formed to have the same size (that is, the shapes of the blades 5a were all the same), the following problems occurred.

That is, when the size of the cutting edge surface 5a of the blade 5a is small, the blade 5 along with the cutting edge surface 14a
There is a problem that the amount of input material placed on the rear back surface (conveyance surface) 14b that defines the area a is reduced, resulting in poor processing efficiency. Further, in this case, if the input material to be processed is large or deformed, the input material may float on the blade 5a, making it impossible to cut it. This tendency is particularly strong when processing cutting chips that have been deformed into a curled shape. On the other hand, if the size of the cutting surface 14a of the blade 5a is large,
Although the processing efficiency is good, on the other hand, since the amount of processing increases, there is a problem that the load applied to the shafts 3 and 4 increases.

The present invention has been developed in view of the above, and an object of the present invention is to provide a cutting type crusher that can efficiently cut large and small or deformed input materials without imposing too much load on the shaft.

The above and other objects and novel features of this invention will become clear from the description of this specification and the accompanying drawings.

[Means for Solving the Problems] An overview of typical devices disclosed in the present application is as follows.

That is, in the cutting type crusher, each disk is constructed by alternately disposing two types of blades having different cutting surface sizes in the circumferential direction thereof.

[Function] According to the above means, the blade with a small cutting surface works to efficiently cut a relatively small input material, and the back surface can easily transport large or deformed input materials to the cutting position. Work like you do. On the other hand, blades with large cutting surfaces serve to cut relatively large input materials. the result,
The above object of cutting large and small or deformed input materials efficiently and without applying too much load to the shaft can be achieved.

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

Figure 1 shows the first cutting type crusher according to the present invention.
FIG. 2 shows a schematic structure of a disk which is the main part of the first embodiment, and FIG. 2 shows a schematic structure of the first embodiment.

The cutting type crusher of this embodiment differs greatly from the conventional one in that a blade 22 with a small cutting surface 22a and a cutting surface 23a are provided on the outer periphery of the disk 21.
The large blades 23 are arranged alternately. That is, in the disk 21 of the embodiment, the central angles at which the blades 22 and 23 stand are different (θ ₁ , θ ₂ ), so that the size of the rear surface 22b of the blade 22 is larger than that of the rear surface of the blade 23. 23b
is larger than the size of Furthermore, the rotational force is transmitted from the motor (not shown) to the shaft 3 by the chain 31, and the cylindrical metal 32 is provided inside the bearing 2.
Different from conventional ones. Here, the cylindrical metal 32 has a function of supplementing the bearing action of the bearing 2 and also has a function of preventing dust and the like from adhering to the bearing 2. The rest of the structure is similar to that of the conventional cutting type crusher shown in FIG. Therefore, the same elements are given the same reference numerals as in FIG. 10, and their explanation will be omitted.

In the cutting type crusher configured in this way,
For example, when input materials of different sizes are input, relatively small input materials are conveyed to the cutting position by the rear surfaces 22b, 23b of the blades 22, 23, and the blades 23, which are continuous with the rear surfaces 22b, 23b, 22 cutting edge surfaces 23a, 22a. On the other hand, large input materials or deformed input materials that cannot be floated and transported by the rear surface 23b of the blade 23 are transported by the rear surface 22b of the blade 22.
b to the cutting position, and the rear surface 22
It is cut by the cutting edge surface 23a of the blade 23 that continues from the point b.

Therefore, according to the cutting type crusher of the embodiment configured in this way, it is possible to easily cut large and small or deformed input materials efficiently and without applying too much load to the shaft.
