Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention provides a method of
Regarding the improvement of a cutting blade for a chopping device that cuts vertically and horizontally at the same time by reciprocating motion in the vertical direction, it is particularly important to improve the cutting blade for a chopping device, which cuts both vertically and horizontally at once, especially for crude drugs, woody substances such as cinnamon, licorice, wood, and bonito, or completely dried bonito flakes, etc. , relates to a cutting blade that cuts rather hard materials.

[Prior Art] Conventionally, cutting blades used in chopping devices that cut objects by reciprocating motion in a direction perpendicular to the feed direction have generally been food-grade cutting blades.
In particular, in order to improve productivity and workability, a cutting blade with a vertical and horizontal double blade structure is provided, which combines multiple vertical blades in addition to a single horizontal blade (1987-
No. 51833, Jitko No. 28-3885).

[Problems to be Solved by the Invention] However, the cutting blade disclosed in Utility Model Publication No. 57-51833 has one edge of the vertical blade fitted into a plurality of recesses arranged in parallel on the horizontal blade, and the edge of the other side Since the upper half of the blade is screwed to the horizontal blade by a holding member, the vertical blade is directly fixed to the horizontal blade, and the vertical blade is also fixed to the horizontal blade from the vertical direction. Therefore, there are few problems with foods such as carrots and radishes, but when cutting rather hard wood-based materials such as herbal medicines, it is difficult to resist the stress in the lateral direction, that is, the width direction. Moreover, since the vertical blades are individually fixed in principle, there was a problem in that each vertical blade was subjected to a considerably large cutting stress.

In addition, with the structure in which the vertical blades are individually fixed to the horizontal blades, it is difficult to immediately deal with partial breakage of the horizontal blades, which is particularly likely to occur when cutting this type of herbal medicine, etc. It is also necessary to grind each vertical blade individually, making it necessary to replace the entire vertical and horizontal blades.

On the other hand, the invention disclosed in Utility Model Publication No. 28-3885 has an independent structure for the vertical and horizontal double blades, so it is possible to deal with damage to the horizontal blades independently of the vertical blades, which is preferable. Horizontal blades are attached to a horizontal frame at regular intervals, so they have the disadvantage that they can only cut pieces of a certain size according to the distance between them. It was impossible to obtain crude drugs. Moreover, because simultaneous cutting is not possible due to the structure, the cutting condition is uncertain, and the cut shape is not uniform.
There is a drawback that uniform size cannot be obtained. In addition, in each of the conventional techniques, the structure is such that the horizontal blade is placed in the front and the vertical blade is placed in the rear with respect to the feeding direction of the material to be cut. The fourth
As shown in the figure, there inevitably arises a portion B that is cut twice, resulting in a double-cut workpiece 13 as shown in FIG. 5, which poses a problem in that uniformly shaped workpieces cannot be manufactured at a high yield. In FIG. 4, the solid line 〓 indicates the cutting line, and four cutting lines are shown.

Therefore, the problem of this invention is to solve such problems, and it is possible to cut wood-based rather hard materials such as crude drugs with sufficient durability with both vertical and horizontal blades. To provide a cutting blade for a chopping device for crude drugs, etc., which requires easy maintenance such as blade replacement, can cut into uniformly shaped pieces, and eliminates the occurrence of double-cut processed products.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a blade receiving member and a cutting blade, each having vertical and horizontal double blades independently of each other, and fixed to a cutting blade device position of a cutting device. It has a polymerized integral structure in a fixed state in which it is sandwiched between a blade holding metal fitting that presses from the outside against the receiving member, and a plurality of vertical blades are arranged parallel to each other via spacers for each blade, and the left and right blades are It is unique in that it is bolted from both ends, and the vertical and horizontal blades overlap, with the vertical blade in the front position and the horizontal blade in the rear position with respect to the feeding direction of herbal medicine, etc.

[Operation] Therefore, since both blades have a mutually independent structure,
Any damage to the blade can be dealt with immediately, making maintenance extremely easy. Moreover, the vertical blade itself has an independent structure that fixes all the blades in the horizontal direction at once, and since both the vertical and horizontal blades are pressed into the device itself by the presser metal fitting, the cutting power of the vertical blade is especially strong. Become. In addition, both the vertical and horizontal blades have a polymerized integrated structure, so they can be cut at the same time.Moreover, since the vertical blades are placed in the front position with respect to the feeding direction of crude drugs, etc., the strain caused by the feeding of the presser roll and presser plate of the cutting device Since there is no influence, there will be no double cuts. Therefore, a large number of uniformly shaped strips of crude drugs can be produced at once.

[Example] In Fig. 1, reference numeral 1 denotes a cutting blade for a chopping device with vertical and horizontal dual blades that cuts crude drugs, etc. by reciprocating motion in a direction perpendicular to the feeding direction A; On the other hand, the vertical blades 2 are overlapped at the front position, and the horizontal blades 3 are overlapped at the rear position. Note that a is the crude drug to be cut.

As shown in FIG. 2, this cutting blade 1 has a vertical blade 2 and a horizontal blade 3 that are configured independently of each other, and a blade receiving member 4 fixed to the cutting blade mounting position of the cutting device A. It has a superimposed integral structure in a fixed state in which it is sandwiched between a blade retainer 5 that presses from the outside against the blade receiving member 4, and as shown in the figure, a plurality of vertical blades 2 are inserted through spacers 6 for each blade. They are arranged and fixed in parallel to each other.

Therefore, when the cutting blade 1 moves up and down in a reciprocating motion in a direction perpendicular to the feeding direction of the herbal medicine, the fed herbal medicine is simultaneously cut by the vertical blade 2 at the front and the horizontal blade 3 at the rear. Ru. Since the cut fragments are separated from the uncut portion of the herbal medicine by the rear horizontal blade 3, the cut fragments are not cut twice. Therefore, by such simultaneous cutting, a large amount of uniformly shaped pieces can be obtained at once.

In FIG. 2, reference numeral 7 denotes a blade attachment portion of the engraving device A, to which the blade receiving member 4 is fixed. The blade receiving member 4 also has the function of preventing the blade of the horizontal blade 3 from warping due to the pressing force of the vertical blade 2. Reference numeral 8 denotes oyster removing blades, which are arranged in such a manner that the comb-shaped blades fit between the vertical blades 2, and are attached to the blade attachment member 7. 9 is a presser roll of the cutting device; 10 is a presser plate;
11 is a vertical blade presser.

However, the present invention is not limited to the above embodiments.
For example, as shown in FIG. 3, the cutting blade 12 may be inclined in the direction opposite to the feeding direction. In this way, the force in the feeding direction can be effectively resisted, and the cut surface becomes beautiful.

[Effects of the Invention] As described above, this invention has the vertical and horizontal blades each having an independent structure, is strongly polymerized, and has the vertical and horizontal blades arranged in reverse, which is different from the conventional arrangement. Speaking of which, both the vertical and horizontal blades are durable enough to cut hard materials, and maintenance such as replacing the blades is also easy, and it can be cut into uniformly shaped strips, and can be cut twice. It was possible to provide a cutting blade for a chopping device for crude drugs, etc., which does not generate any waste.
