Description

[Detailed Description of the Invention] This invention relates to a rotary cutter for a cooking machine, such as a food cutter, whose blades can be replaced in various ways.

A cooking machine such as a food cutter has a rotary cutter blade that is replaceable so that it can be used for several types of cooking, such as for cutting into slices or for cutting into rounds.

The advantage of a rotary cutter with such a replaceable blade is that the blade can be attached and detached quickly and easily, and once the blade is attached, it does not come off unexpectedly even when the rotary cutter rotates at high speed. It is requested that there be no such thing.

Therefore, the present invention aims to provide a rotary cutter that satisfies the above requirements while having a simple configuration.

To explain the embodiment with reference to the drawings, in Fig. 1, 1 is the cooking machine main body, and the cooking machine of this embodiment has two drive shafts for high speed and low speed by a motor (not shown) that can be installed inside the main body. A low-speed drive shaft 2 consisting of a hexagonal cylindrical hollow shaft receives the driving force of a motor into a pulley 3 fitted to its lower end, and is driven to rotate. However, this low-speed drive shaft 2
The upper body part of the hood cutter 5 is used as a fitting base 4 for an attachment such as a hood cutter, and the rotary cutter of the hood cutter 5 mounted on the hood cutter 5 is attached to the hood cutter 5. It penetrates the bottom of the container 6 and is detachably attached to the drive shaft 2.

Next, in more detail about the rotary cutter 7 according to this invention, the rotary cutter 7 of this embodiment has a hexagonal prism-shaped rotary shaft 8 that can be fitted into the hollow low-speed drive shaft 2, and an upper end of the rotary shaft 8. It is composed of a rotary plate 10 made of a molded door made of resin and fixed thereto, and a blade plate 11 made of a molded steel door removably attached to the rotary plate 10 across its center of rotation. , the rotating plate 10 and the blade plate 11 are
According to this idea, each is structured like a law.

That is, as shown in FIGS. 3 and 4, on the upper surface of the rotating plate 10, a recess 12 for attaching the blade plate of the instep W is formed at a position crossing the center of rotation. There are recesses 12 on both sides of the center of rotation of place 12 (upper and lower in Fig. 4).
A pair of window holes 13 are formed through the entire width of the recess 12.
The blade plate fitting groove 1 spans the entire length of both sides along the longitudinal direction.
4 is formed.

In this embodiment, the blade plate fitting groove 14 extends between the inner side wall 15 of the window hole 13 and the rising walls 16 on both sides of the portion of the recess 12 that does not pass through the window hole 13. , is formed by a row of protrusions 17 arranged vertically alternately and protrudingly provided.

Next, when explaining the blade plate 11, this blade plate 11 is as follows.
As shown in FIGS. 6 to 8, an arbitrary blade 18 for chopping or round cutting is provided on the plate surface, and the width is equal to the width between the blade plate fitting grooves 14. The door is made of a press-formed steel plate, and its peripheral edge is bent downward (11a) to form a flat box-shape, and the edges of both sides along the longitudinal direction have the above-mentioned downward folds. Bending part 11a
Subsequently, a retaining lip 20 is formed to protrude laterally, and this retaining lip 20 can be inserted into and removed from the side from the side into the blade plate fitting groove 14. The blade plate 11 has the engaging lip 20
When the blade plate 11 is engaged with the blade plate fitting groove 14 and installed in the blade plate mounting recess 12, the upper surface of the blade plate 11 and the upper surface of the rotary plate 10 are kept flush with each other by the engaging lip 20. It's starting to drip.

In the center of the blade plate 11, a pair of tongue pieces 21 are formed by cutting out a U-shape from the plate surface and protrude downward so that the cross section is V-shaped (FIG. 8). A pair of stopper engaging recesses 24 each consisting of two small protrusions 23 are formed at appropriate central locations of the blade plate mounting recess 12 on the rotating plate 10. The stopper 22 and the stopper engagement recess 24 constitute a mechanism for fixing the blade plate 11 onto the rotary plate 10 when the blade plate 11 is installed into the recess 12 from the side. -ing

In addition, 25 is a hole drilled in the surface of the rotary plate 10 so that the rotary cutter 7 can be hooked through the finger when the rotary cutter 7 is taken out from the container 6, and 26 is a tongue piece formed at one end of the blade plate 11 to protrude downward. It is.

Since the rotary cutter 7 of this invention has the above-mentioned configuration, it can be used in the following manner.

That is, first, in order to fasten the blade plate 11 to the rotating plate 10, the retaining lip 20 of the blade plate 11 is engaged between the blade plate fitting grooves 14 from one side of the recess 12 of the rotating plate 10. When it is tightened and inserted and pushed into the specified position, the stopper 22 provided at the center of the blade plate 11 will temporarily ride on the small protrusion 23 provided on the rotary plate 10, and then the two small protrusions will be removed. It is elastically fitted into the stopper engagement recess 24 between 23 and fixed on the rotary plate 10.

Note that, like the blade plate 11 in the embodiment, the blade plate 11 is replaced by the rotary plate 1.
The blade plate 11 is configured so that it can be inserted into the recess between the blade plate fitting grooves 14 on the 0 from either the left or right direction, and a tongue piece 26 is provided at one end of the blade plate 11. , the tongue piece 2
6 is in contact with the outer peripheral edge of the rotary plate 10, the blade plate 1
1 is installed at a predetermined position in the recess, and the stopper 22 is correctly fitted into the stopper engagement recess 24, when the blade plate 11
Not only can the blade plate 11 be easily installed in the correct position from either the left or right direction into the recess on the rotary plate 10, but also the blade plate 11 can be easily installed from above the rotary plate 10 by placing a finger on the tongue piece 26. It is convenient because it can be removed.

As is clear from the above explanation, the rotary cutter according to the invention is such that the blade plate is mounted on the rotary plate by being inserted between the blade plate fitting grooves provided oppositely on the rotary plate. Because of this, the blade plate does not come off above the rotating plate even during high-speed rotation, and the blade plate has a stopper formed by cutting and raising the plate surface of the blade itself and a stopper on the rotating plate. By fitting into the engagement recess, it is elastically engaged on the rotary plate, so when installing it, simply push the blade plate and quickly place it on the rotary plate. In addition, the blade plate can be easily fixed, and once the blade plate is fixed on the rotary plate, it is securely fixed on the rotary plate and will not be unexpectedly released even during high-speed rotation, and the blade plate will remain secure. When removing the plate, the blade plate can be easily removed from the rotary plate by pulling or pushing out the blade plate with the same force as when it was attached. Since it is a resin molded product and the blade plate is a press-molded metal plate, there is little frictional resistance between the blade plate fitting groove and the blade plate, so it is easy to insert the blade plate between the blade plate fitting grooves. The extraction operation from between the grooves can be performed smoothly, and the simple structure of both makes manufacturing simple and easy, especially when the blade plate is fitted onto the rotary plate as in the above embodiment. When the grooves are formed by rows of protrusions arranged vertically and alternately, manufacturing is simpler and easier than when forming a series of narrow grooves, and a high degree of finishing accuracy is also obtained. It has the advantage of being easy to use.
