Abstract

PURPOSE: To smoothly make powder a material containing much oil such as peanuts and to crack a waste material such as jeans to a fibrous state. CONSTITUTION: A material to be worked (a) in a cylinder 3 is pressed on a rotary disc 2 by a piston 6 to pulverize it by cutting. The cutting surface thereof is formed by a cutting blade standing inclined in the rotating direction of the disc. The cutting blade tears and cuts the material to be worded to pulverize it. Compressed air is blown to the disc 2 from a nozzle 4 to eliminate the clogging of the cutting surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the processing of oily materials such as peanuts, high-fat bonito, and higher fatty acid-containing products, pulverization of dried fish, fibrillation of meat, silk cloth, and jeans. The present invention relates to a cutting and crushing method and an apparatus therefor for performing fibrous disintegration of waste materials such as cloth, paper and leather.

[0002]

TECHNICAL BACKGROUND As a means for performing the above-mentioned pulverization and disassembling, the inventor of the present application has developed a pulverization method and apparatus described in Japanese Patent Publication No. 2-6574. This means, in the cylinder,
The work is compressed and filled, and the work in the compressed state is pressed into contact with a grinding surface that moves relative to the cylinder and ground to obtain powder.

By the way, in recent years, powdery products such as peanuts, high-fat bonito, and the like having a lot of oil have been demanded. In addition, from the perspective of reusing resources, waste materials such as silk cloth, jeans cloth, paper, leather, etc. are broken into fibrous materials, and the fibrous materials are made into paper-making materials through various binders (binding materials). It can be used as a decorative material with a great number of new sensations, such as by pasting it onto the surface of a shape or cloth by hot pressing, or the surface of cloth or board with an adhesive. There is a demand for a food with a crunchy new sensation.

[0004]

The grinding tool used in the technique described in the above publication is a so-called grindstone, and its crushing is a grinding type and a grinding type, and the grinding surface is clogged. Was likely to occur. For this reason, the above-mentioned oily work such as peanuts becomes buttery due to mashing and cannot be powdered to obtain a desired product. Further, clogging is severe and smooth crushing cannot be performed.

Further, the fibrous disintegration of waste materials such as jeans is powdery with the grinding tool, and a desired product cannot be obtained.

Under the above circumstances, it is an object of the present invention to smoothly grind an oily work piece and to disintegrate waste material such as jeans into a fibrous shape.

[0007]

In order to solve the above-mentioned problems, in the invention according to the crushing method described in claim 1, the work 3a is compressed and filled in the cylinder 3 and the compressed state is maintained. The work piece a is pressed against a cutting surface that moves relative to the cylinder 3 to cut the work piece a, and compressed air is applied to the cutting surface of the cutting surface except for a portion where the work piece a is pressed. It was sprayed to remove the clogging of the cutting surface.

In the invention relating to the crushing apparatus according to the second aspect, the rotating cutting disk 2 is provided with the cylinder 3 orthogonal to the cutting surface, the end surface of which is close to the cutting surface.
A configuration in which a compressed air jetting nozzle 4 is made to face another position of the cutting surface of the cutting disk 2 close to the cylinder 3, and a piston 6 for pushing the workpiece a to the cutting surface is provided in the cylinder 3. It was.

According to a third aspect of the present invention, in the above-mentioned second aspect of the invention, the cutting surface of the cutting disk 2 is innumerable in a number of cutting edges 2a which stand upright in the rotational direction of the cutting disk 2.
That is, the structure is formed by.

[0010]

According to the present invention having such a structure, since the crushing is performed by cutting, the crushing is not performed by grinding but is performed by the slitting action, and the cutting surface is freed from the clogging by jetting compressed air. It For this reason, the oily work piece is smoothly pulverized, and the waste material such as jeans is broken into fibers. At this time, the cutting blade 2a that is inclined in the rotation direction of the cutting disk 2 cuts (cuts) the cutting disk 2a.
The action is smooth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment is shown in FIGS.
A rotating disk 2 made of stainless steel is provided inside, a cylinder 3 orthogonal to the cutting surface is provided below the cutting surface of the disk 2, and its end surface is provided in the vicinity thereof, and a compressed air jet nozzle 4 is provided above the cutting surface of the disk 2. Face. Cylinder 3 and nozzle 4
The position of is arbitrary within a range that does not interfere with the cutting action and the clogging prevention action described later.

As shown in FIG. 2, the cutting surface of the cutting disk 2 is formed by cutting and raising the disk surface, and forming a cutting edge 2a inclined and standing up in the rotation direction (arrow direction) over the entire cutting surface. The cutting blade 2a cuts the workpiece a by cutting it like a planer blade. The rising angle α of the cutting edge 2a is preferably around 45 degrees.

The cylinder 3 may have any shape such as a circular cross section or a polygonal shape, in which the piston 6 is movable back and forth. Therefore, when the workpiece a is put into the cylinder 3 and the piston 6 is advanced, the workpiece a is pressed against the cutting surface of the disk 2 in a compressed state.

Now, with the cutting disk 2 rotated,
When the waste material a of jeans is filled in the cylinder 3 and the piston 6 is advanced, the waste material a is compressed and pressed against the cutting surface,
The product is disintegrated into fibrous products a ′ shown in FIG. 3 by being cut by the cutting edge 2a. The product a ′ is collected in the container 7.

During this cutting action, compressed air is ejected from the nozzle 4 to remove the clogging between the cutting edges 2a (cutting surface), and to perform a smooth cutting action.

In the same manner, waste materials other than jeans, silk cloth, paper (newspaper), leather, etc. were obtained in the same manner with a smooth cutting action to obtain a fibrous product a '.

Further, when peanuts, bonito and other oily substances were similarly cut, smooth cutting was possible without clogging, and a powdery product a'was obtained.

Further, when the fish meat (dried fish) was cut in the same manner, a fibrous product a'shown in FIG. 3 was obtained.

[0019]

Since the present invention is constructed as described above,
It is possible to smoothly cut and grind a greasy work piece, and to disintegrate waste materials such as jeans into a fibrous shape, which can greatly contribute to the development of new products and the reuse of resources. is there.
