The plate (4) has a predetermined shape and number of small-diameter through holes (4a) (4a) on the entire surface, and a round hole in the center with a size that allows the cylindrical portion (3b) to fit therein. (4b)
is drilled.

The first force 7 (5) is, for example, a cross-shaped four-blade cutter as shown in the figure, with the first rectangular body (3a
) is provided with a rectangular hole (5a) that can be fitted into the hole (5a).

The second cuff (6) is, for example, a two-blade cutter having a shape as shown in the figure, and has a square hole (6a) bored in the center that can fit into the second square body (3c). There is.

The rotating shaft (3), the plate (4), and the first and second cuffs (5) and (6) are assembled into the body (1) in the following manner.

First, attach the first cuff (
Fit the square hole (5a) of 5).

Next, with the plate (4) engaged with a detent key (not shown) formed on the body (1), the cylindrical portion (3

The chopper directs the raw material supplied into the body (1) from a hopper (not shown) to the first canter (5) using the screw (2).

While cutting these raw materials with the first cutter (5), the through holes (4a) (4a)...
This raw material is further extruded from the through holes (4a) (4a) of the plate (4), and then cut by the second cutter (6) to form a predetermined product.

(The eyes that say 1°) The above-mentioned chamber had the following problems.

First, the second cuff (6) and the rotating shaft (3) are
While the chopper is operating, a reaction force toward the rA side due to the feeding of raw materials acts on the screw (2).1. Because the screw (2) is pulled toward the back of the body (1) due to this reaction force, the nut (8) must be tightened when attaching the second force (6) to the rotating shaft (3). It is difficult to adjust the force when attached.

Second, the screwing direction of the NAND (8) is the rotation axis (
3) Because it tightens easily in the direction of rotation,
While operating the Chirotsuba, the above nut may be tightened more than necessary.
The second cutter (6) is strongly pressed against the plate (4) to accelerate the wear of the second cuff (6).

Thirdly, as mentioned above, it is difficult to adjust the force when tightening the nut (8), so it is difficult to tighten the nut (8) further in response to wear and tear on the second cutter (6).

The present invention has been made in view of the above problems, and includes a rotating shaft integrally connected to a screw for feeding raw materials, and a shaft hole in the center of the rotating shaft. In the chopper, the body houses a perforated plate which is rotatably supported by the perforated plate, and a cutter which is disposed on at least the surface side of the perforated plate and rotates integrally with the rotary shaft while slidingly contacting the perforated plate. This is a chopper in which a spring holder with a diameter larger than the rotating shaft is fixed to the tip of a rotating shaft, and a predetermined number of disc springs are compressed and interposed between this spring holder and a canter placed on the surface side of the above-mentioned porous plate. be.

Since the space between the plate and the plate is covered by the bushing/sing (16), uncut raw material is prevented from flowing out through the space to the front side of the plastic plate (13).
In addition, the cutting edge (14c) of the first cutter (14)
(14c)... are formed substantially in the radial direction as described above, so no radial force acts on the raw material being cut, and the raw material is uniformly cut only by the circumferential force.

Through holes (13a) (13) of the plate (13)
a) - The raw material pushed into the above-mentioned through hole (13a
') (13a) --- is compressed while passing through the through-holes (13a) (13a) --- and is sequentially cut into particles by a second force, ri (15). .

By the way, in the process of cutting the raw material using the second cutter (15), the cutting blade (15,c) (15c)...
Since the is formed approximately in the radial direction, no radial force acts on the raw material being cut, and the raw material is uniformly cut only by the circumferential force, so the above granular product has a uniform length. becomes.

The functions of the above chisso bar will be explained below.

In the above chopper, the rotation shaft (12) is slidably supported on the entire surface of the shaft hole (13a) of the plate (13), so the support strength of the first rotation shaft (12) is high, and
2) has the same cross-sectional shape over the entire length, so the thickness and number of plates and cutters can be changed as appropriate! It is possible to easily adapt to changes in the purpose of use of the F7 bar.

In addition, in the above-mentioned Chisso bar, the second cuff (15) is always played by a predetermined number of disc springs (17) that are compressed and interposed between the second cuff (15) and the spring retainer (18) at the tip of the rotating shaft (12).
(13), so the second
Cutting blade (15c) (15C) of cutter (15)...
Even if it wears out, play with the second kofta (15)) (13)
This can prevent play from occurring between the two.

In addition, in the above-mentioned Chisso bar, there is no need to separate the punching (16) from the cutter, which prevents uncut raw materials from flowing out onto the surface of the plate, and as shown in FIGS. There is a tongue piece (16c') (
16c') may be formed integrally.

Furthermore, the present invention is not limited to choppers that produce granular products, but can also be effectively applied to nitrogen bars that produce paste products, powdered products, and the like.

As explained above, the present invention can be applied to a variety of products. With the t7 par, there is no need to retighten the Nand according to the wear of the cutter as in the past, and the cutter can be easily installed and removed by attaching and detaching the spring holder at the tip of the rotating shaft with a bolt. Since the number and thickness of the plates and canters attached to the rotating shaft can be changed by changing the size, number, or elastic force of the disc springs, it is possible to provide an extremely practical chopper.
