The present invention crushes, cuts, breaks down, breaks down, breaks down, breaks down, breaks down, breaks down, breaks down, breaks down, breaks down, etc. It relates to a cutlery structure of a cutting device.

The applicant has obtained the rights of Korean Patent No. 184318. The name of the invention is "crushing and cutting methods and apparatuses for casting, tapping, defective products, etc.", and the blade paste structure is shown in Figs. The outline is demonstrated below.

In the example of FIG. 8, in the blade body, a plurality of mountain-shaped fixed blades are provided in a zigzag shape, and a plurality of mountain-shaped movable blades are provided in a zig-zag shape in a blade body that replaces the fixed blade device. It consists of a movable blade unit, and the fixed blade and the movable blade are engaged, and the engagement gap is formed between this fixed blade and the movable blade. Therefore, as shown in FIG. 8 at the time of crushing the mold release cup shown as an example in FIGS. 6 and 7, the jaw portion is large in mold release, for example, with a fixed blade device. It is in a state suspended in the air by being interposed between the fixed blade and the movable blade which are opposed at the lower side (outlet side) of the movable blade pasting device. In this suspended state, the movable blade does not fall even if it retreats, and when the movable blade moves forward, it does not fall and is broken up, and it remains unbreakable even when pressure is applied, and it cannot be removed. . In order to overcome this situation, it requires a lot of trouble in stopping the apparatus, taking out the release cups and / or other crushed casting products (fragments) suspended in the air, or crushing the ejected release cups. Problems, such as a concern and the efficiency become worse, can be considered. And in the situation where it hangs in the air, even if a movable blade sticks forward and backwards several times, this situation does not change and it cannot be removed. Moreover, the space | interval between the lower fixed blade stick and the movable blade stick is large, and the problem, such as a thin long thing falling from the space | interval, can be considered. Moreover, even if it is a crushed object, when it is large, it can be considered similarly to a mold release cup.

In the example of FIG. 9, as an example of improvement to the example of FIG. 8, a plurality of mountain-like movable blades are provided in a zigzag shape on the blade body constituting the movable blade device, and the band shape is located below the blade body. With the structure provided with a cutlery, in this strip | belt-shaped cutlery, an elongate thing like a water run is prevented from falling from a space | interval. However, also in this example, when it is set to the state suspended in the air (it shows a crushed thing) similarly to the example of FIG. 8, there exists a substantially same problem.

In addition, in the example of FIG. 10, as an example of the improvement of the example of FIG. 8, FIG. 9, in the blade body which comprises a fixed blade device, a plurality of mountain-shaped fixed blade blades are provided in a zigzag shape, and below this blade blade body. With the structure provided with the strip | belt-shaped blade which is located in this strip | belt-shaped blade, the long thing avoids falling from a space | interval, for example, as a water run. However, in this example, the distal end face of the band-shaped blade is protruded much larger than the distal end surface of the fixed blade. Therefore, if the band-shaped blade cutter acts like a fixed blade holder and is suspended in the air (as shown in Fig. 8), as in the example shown in Fig. 8, there is approximately the same problem. In addition, since the strip-shaped blade is disposed above the movable shaft, the distance from the lower jaw of the blade main body of the movable blade device decreases, which causes a blockage of the debris (typically showing the debris). Therefore, like the example of FIG. 8, it becomes easy to be suspended in the air, and has the same problem. In some cases, problems are likely to occur even in a plastically deformed state, and room for improvement is considered.

With respect to the applicant's patent described above, in the use mode in Korea, there is a fear that the above-described problems or improvements may occur. Accordingly, as a result of examining the Korean use mode according to the conventional prospect, the present invention proposes a cut-and-paste structure of a crushing / cutting device such as casting, tapping, or product for casting.

Its purpose is to reduce defects, improve efficiency, speed up, etc. through reliable shredding.

The invention of claim 1 avoids a state in which the crushed matter generated between the fixed blade and the movable blade (replaced with the fixed blade and the movable blade) opposed to the fixed blade device and the movable blade device is suspended in the air, or This avoidance aims at securing continuous operation, facilitating maintenance, or facilitating extraction of debris, reducing effort, and improving efficiency. In addition, it is intended to prevent the fall from the gap between the fixed blade and the movable blade of the elongated shredding object, and to achieve the above-described effects.

Claim 1 is provided with a fixed blade device in which a plurality of mountain-shaped fixed blades are provided in a zigzag shape on the blade body, and a band-shaped blade is provided in close proximity to the fixed blades positioned below the blade body, and the fixed blade device is replaced with the fixed blade device. As a blade structure of crushing / cutting devices for casting frozen, tap water, products, etc., using a movable blade device in which a plurality of mountain-shaped movable blades are installed in a zigzag shape in a blade body,

The stationary blade and the movable blade are engaged with each other, the engagement gap is formed between the fixed blade and the movable blade, and the end face of the band-shaped blade is protruded from the tip of the fixed blade. It is a cut-and-paste structure for crushing and cutting devices such as frozen, hot water and products

The invention of claim 2 defines a relationship between the fixed blade and the movable shaft of the movable blade, and intends to achieve the same effect as that of claim 1.

Claim 2 has a strip-shaped blade provided below the blade body of the fixed blade device according to claim 1 in the horizontal direction with respect to the movable shaft of the movable blade device. It is a cut structure of shredding and cutting device.

Hereinafter, the action (the situation of crushing and cutting | disconnection) of this invention is demonstrated.

As shown in FIG. 1, the crushed object (preferably a crushed raw material) of the object to be crushed is introduced using the opening interval formed in the state where the movable blade is retracted with respect to the fixed blade. The raw material shredded material is crushed through the whole of the two blades, the engagement intervals, and the like, as the movable blade blade advancing is engaged with the fixed blade blade. In this manner, after the movable blade moves forward by a predetermined stroke, the retracted material is retracted so that the first shredded material is separated between the fixed blade and the movable blade through the interval between the fixed blade, the distal end face of the movable blade, and the engaging side. Fall down. After that, the movable blade advancing again is crushed as described above (of course, the crushing position is different. It will be omitted below). Thereby, the 2nd crushing is complete | finished. After the end of the shredding, the movable blade is retracted and falls in the same manner as described above. For example, the second shredding is completed. The advancing retraction of the movable blade with the above-described operation is repeated once or several times, and the crushed object becomes small. Then, although the lower edge of the fixed blade and the movable blade is reached, in the present invention, (1) the band-shaped tip of the blade-shaped blade protrudes from the tip of the fixed blade, and / or (2) the band shape provided below the blade body of the fixed blade device. Since the blade blade adopts a configuration in which the movable shaft of the movable blade blade device and the horizontal blade are arranged in substantially the same positional relationship, the blade blade is not hung in the air from below but discharged reliably and smoothly. Thereby, the objective of this invention can be achieved.
