Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine for cutting vegetables, foods such as kelp and the like, raw materials for various crude drugs, and more particularly to improvement of the cutting mechanism.

[0002]

2. Description of the Related Art Conventional cutting machines include a guillotine-type cutting machine for vertically cutting a vertical blade, a rotary-type cutting machine for rotationally cutting a milling machine, and one end of a cutter knife. There is provided a shaft-supporting type cutting machine that cuts by rotating a shaft.

[0003]

However, in the guillotine type cutting machine, since the vertical blade cuts while descending, a linear cutting locus is drawn, and a uniform unidirectional force is applied to the entire blade surface. Worked too much and was not always satisfactory in terms of sharpness. In particular, when cutting relatively hard foods, crude drug raw materials, etc., it is often the case that a continuous cutting machine that cuts while cutting the object to be cut is continuously used. When cutting on a mounting surface such as an endless belt, the weight of the vertical blade may directly load on the object to be cut, and it is more appropriate to smash by smashing rather than cutting. Therefore, there is a drawback that a cut object in a dented and crushed state can be obtained. There was also a problem that the blade was sore immediately that it had to be replaced early. Moreover, since it was hit and crushed, it was not preferable because noise was generated.

Since the rotary type cutting machine cuts by the rotating force of the milling machine, it is suitable for slicing soft objects to be cut, but it is difficult to deal with relatively hard foods, crude drug raw materials and the like. Particularly, when cutting relatively hard foods, crude drug raw materials, etc., frictional heat is generated between the material to be cut and it is not preferable. The same applies to the shaft support type cutting machine.

The object of the present invention is to provide foods such as vegetables and kelp,
An object of the present invention is to provide a cutting machine that can satisfactorily cut crude drug raw materials and the like without denting and crushing, does not require early blade replacement, and does not generate noise.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the inventors have made earnest studies on the cutting trajectory with the best sharpness. As a result, I found that it was a cutting method by a knife that I experience on a daily basis. In other words, it is a method in which the blade edge is cut from the upper end of the object to be cut and then cut while being pulled toward you.

If this is applied to a cutting machine, it is achieved by changing the mechanism for raising and lowering the cutting blade from the conventional simple vertical movement type to a type that draws an elliptical cutting locus with the major axis positioned in the horizontal direction. it can.

Therefore, the present invention is a cutting machine having a cutting blade for cutting an object to be cut and an elevating mechanism for the cutting blade, wherein the elevating mechanism is constituted by an eccentric device for giving a cutting locus of eccentric motion to the cutting blade. did.

The eccentric device is not particularly limited, and any device that gives a cutting locus of eccentric motion to the cutting blade can be adopted, but normally, a crank arm is attached to a main shaft to which a rotary motion is given, A crank device is preferable in which a lift plate equipped with a cutting blade is attached to the end of the crank arm.

[0010]

According to the present invention, in a cutting machine provided with a cutting blade for cutting an object to be cut and an elevating mechanism for the cutting blade, the elevating mechanism is constituted by an eccentric device for giving a cutting locus of eccentric motion to the cutting blade. Since it is a cutting machine, the cutting blade follows the cutting locus of the ellipse, and the cutting speed of the blade remarkably accelerates as it moves from the long axis of the ellipse to the end axis and further in the long axis direction.
Even when cutting relatively hard foods, raw materials for crude drugs, etc. continuously on the mounting surface such as an endless belt, the blade edge cuts from the upper end of the object to be cut, draws an arc, and pulls in a sudden movement toward you Cut off.

Therefore, it is possible to cut in the state where the sharpness is the best, and it is not crushed by hitting as in the conventional case, so that it does not become a dented and crushed cut product. In addition, the blade does not immediately hurt, and the need for early replacement is eliminated. Also, no noise is generated.

In FIG. 1, reference numeral 23 denotes a pressing member for the object 6 to be cut, which inputs and releases the pressed state according to the intermittent rotation of the drive roller 4.

Since the cutting machine of this embodiment is as described above, the intermediate gear 22, the transmission gears 21, 21 and the crank 1 are driven by the motor and the gear and belt transmission mechanism.
The two main shafts 14 and the bearing box 11 sequentially rotate, and as a result, the lift plate 1 integrally fixed to the bearing box 11.
0 gives an eccentric movement to the cutting blade 8. On the other hand, the above-mentioned motor drive intermittently rotates the drive roller 4 at the same time, so that the object 6 to be cut on the endless belt 3 is intermittently conveyed to the cutting device 2 and is eccentrically moved while being pressed by the pressing member 23. It is cut by the cutting blade 8 descending at.

That is, the cutting blade 8 is, as shown in FIG.
From the point of 8a, it descends to 8b and 8c while drawing an ellipse, cuts the cut object 6, and moves to 8d. Just like when cutting with a knife, a pulling force acts on the object 6 to be cut, and the object 6 is cut at a sharp cut edge. Therefore, as in the past,
Because it is not cut while striking, it can be cut well,
There is no early blade replacement and no noise.

The present invention is not limited to the above embodiment. For example, although the crank device is used as the eccentric device of the lifting mechanism, other eccentric devices may be used. The cutting blade is also a vertical blade, but a blade having another shape such as a round blade may be used. Further, in the above embodiment, the continuous device using the endless belt is used, but a continuous device by other means may be used, and the cutting point is on the endless belt, but the cutting may be performed at another position. Further, it can be configured as a discontinuous device.

It is also possible to install the cutting blade at an inclination angle with respect to the traveling direction of the endless belt, in which case the cutting efficiency is further improved.
