Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutter device for a food processor.

In food processors, different cutters are used for cutting ingredients, such as slicing, shredding, and grating.

As a result, it is difficult to set up the cutter in use, and the storage case for storing each cutter also becomes large.

There are some devices that allow cutters for different purposes to be detachably attached to a common cutter holder, but the installation process is troublesome as it requires a strong attachment to prevent them from falling off due to cutting resistance. There is also a risk that the cutter removed from the machine may be lost.

The present invention is capable of eliminating the above-mentioned drawbacks, and particularly aims to provide a cutter device for a food processor that has good rotational balance.

This invention provides a cutter stand that is connected to a drive unit and rotates about a vertical axis in a container into which materials are input, and a plurality of single-sided cutters each having a cutting blade for a different purpose formed on one side or a cutter for a different purpose. A double-sided cutter having blades formed on both sides is provided, and the single-sided cutter or double-sided cutter is mounted on the cutter stand so that it can be rotated in a horizontal plane with an axis passing through its center of gravity and fixed in the horizontal plane. It is something to do.

Therefore, by reversing the single-sided or double-sided cutter, the cutting blade depending on the application can be set facing upward.This makes it easy to select and set the cutting blade, and the cutter that is not in use can be It is possible to significantly reduce the space required to store the blades that are always held on the cutter stand, and to prevent accidents such as loss.In particular, single-sided or double-sided cutters are reversible, and the blade reversal moment when the axis of rotation passes through the center of gravity can be avoided. In addition, even when multiple single-sided or double-sided cutters are installed, their centers of gravity can be kept on approximately concentric circles centered on the center of the cutter table. By arranging single-sided or double-sided cutters in accordance with the above, rotational balance is good, vibration and noise generation can be effectively suppressed, and cutting performance can also be improved.

An embodiment of this invention will be described based on the drawings.

Reference numeral 1 denotes a base, and a container 4 closed by a lid 3 having a material input port 2 is detachably attached to the base 1.

A spindle 5 protrudes from the center of the bottom of the container 4, which is connected to a motor (not shown) as a drive unit within the base 1 and rotates about a vertical axis.

A cutter table 6 driven by this spindle 5 is provided.

This cutter base 6 is made by connecting a lower ring 8 and an upper ring 9 with a screw 10 to which a rotating shaft 7 is removably attached, which is fitted to the spindle 5 so as to be prevented from rotating but slidable in the axial direction. .

A circular space 11 is formed at the center of the cutter base 6 by joining the lower ring 8 and the upper ring 9, and three ribs 13 radiate from a cylindrical boss 12 surrounding this space 11. It is formed.

Then, single-sided cutters 14, 15, 16, each made of steel and shaped like a fan, are provided.

The single-sided cutter 14 has a cutting blade 17 for shearing, the single-sided cutter 15 has a cutting blade 18 for grating, and the single-sided cutter 16 has a cutting blade 19 for slicing.

These single-sided cutters 14, 15, and 16 have support shafts 20, 21 fixed at the center of their base and periphery that are rotatably and axially inserted into fitting holes 22 formed in the joint surfaces of the upper ring 9 and the lower ring 8. By holding the support shafts 20 and 21 so as to be slidable, the support shafts 20 and 21 can be freely rotated and slid in radial directions.

A slot 23 is formed in the support shaft 21 or 20, and the fitting hole 22 into which the support shaft 21 or 20 is fitted matches the cross-sectional shape of the portion in which the slot 23 is formed.

A single-sided cutter 1 is provided in the space 11 in contact with the support shaft 20.
A ring-shaped spring 2 that biases 4,15°16 in the centrifugal direction
4 is housed therein, and a through hole 25 is formed at the bottom of the space 11 to allow moisture that has entered the inside to escape.

The peripheral edges of the single-sided cutters 14, 15, and 16 that are urged outward are supported by an upward step 26 formed near the outer periphery of the cutter base 6, and a gap 27 is formed between the boss 12 and the lip 13. ing.

Although the single-sided cutters 14 to 16 are different, they have the same outer diameter and the same mass.

Furthermore, the centers of gravity of each of the single-sided cutters 14 to 16 are positioned on a concentric circle centered on the rotation center of the cutter base 60 on the axis of the support shafts 20 and 21 with an interval of 120 degrees.

In the single-sided cutter 16, the cutting blade 19 is offset to one side, and a sacrificial hole 28 is formed on the other side.

Further, a sacrificial hole 29 is formed in the single-sided cutter 14 as appropriate.

By these means, the center of gravity of each of the single-sided cutters 14 to 16 is set at the aforementioned position, and the mass is also made uniform.

In such a configuration, when the motor is driven, the spindle 5 drives the cutter base 6.

In this state, materials such as vegetables and fruits are input from the material input cylinder 2 and various cutting operations are performed.

Depending on the application, one of the cutting blades of 17°, 18, and 19° is selected, and its operation will be explained.

First, push the support shaft 21 to push one of the single-sided cutters 14, 15, and 16 inward.

As a result, the peripheral edges of the single-sided cutters 14, 15, and 16 are removed from the stepped portion 26.

Therefore, the single-sided cutter 14, 15° 16 is attached to the support shaft 20,
21 as a fulcrum, it slides in the centrifugal direction by the force of the spring 24, and is supported by the stepped portion 26 again.

That is, cutting is performed by either of the cutting blades 17, 18, 19 facing upward.

Therefore, the work of selectively setting the cutting blades 17, 18° 19 within the cutting surface can be performed with one touch without using any tools.

Since the unused cutting blades 17, 18, and 19 are also held in a downward position on the cutter stand 6, the storage space is greatly reduced and loss is also prevented.

During cutting, the single-sided cutters 14, 15, and 16 are biased by centrifugal force in addition to the force of the spring 24, so that the amount of overlap with the stepped portion 26 is reliably maintained.

In addition, when reversing the single-sided cutters 14, 15, 16, by forming a slot 23 on the support shaft 21, the length and breadth of the shaft 21 and the fitting hole 22 can be adjusted as shown in FIG. It is possible to set a dimensional difference, and therefore, in the middle of the reversal, as shown in Figure 5, the space between the upper ring 9 and the lower ring 8 is pried open, and the reaction force is used to hold the support shaft 21, so that one side The cutters 14, 15, 16 are stabilized in the horizontal plane, and clear moderation is obtained when reversing.

As described above, since the axis of the single-sided cutters 14 to 16 during reversal is located on the center of gravity, the reversal moment can be reduced to zero unless an external force is applied, and the one-sided cutters 14 to 16 resist the load. can be supported in a stable state, and furthermore,
The centers of gravity of each of the single-sided cutters 14 to 160 are located at equal intervals of 120 degrees on the concentric circle centered on the cutter table 6, and the masses are also equal, so that the multiple single-sided cutters 1
Even when using the number 4 to 16, the rotational balance is good and the generation of vibration and noise can be effectively suppressed.

Of course, this can also improve cutting performance.

The interval in the circumferential direction between the centers of gravity of each single-sided cutter may be changed if the single-sided cutters have different shapes or masses.

The point is that the moment of inertia of each single-sided cutter when the cutter table 60 rotates is made equal to maintain the rotational balance of the cutter table 6 as a whole.

Note that a double-sided cutter in which any two of the cutting blades 17 to 19 are formed on both sides may be mounted on the cutter stand 6 by the same means as the single-sided cutters 14 to 16.

In this case, a plurality of double-sided cutters of the same type may be arranged on the same plane.

Even in this way, the cutting blade 17 to be used by reversing
19 can be selected.

Since this invention is constructed as described above, by reversing the single-sided or double-sided cutter, the cutting blade can be set facing upward according to the application, and this makes it easy to select and set the cutting blade. The unused cutter is always kept on the cutter stand, which greatly reduces storage space and prevents loss of the cutter.
In particular, single-sided or double-sided cutters are reversible;
Since the center of rotation passes through the center of gravity, the reversing moment can be reduced to zero and the load can be supported in a stable state.Furthermore, even when multiple single-sided or double-sided cutters are arranged, their center of gravity is located on the cutter base. By arranging single-sided or double-sided cutters on substantially concentric circles centered on the center and equally spaced in the circumferential direction, the rotational balance is good, and as a result, vibration and noise generation can be effectively suppressed. This has the effect of improving cutting performance.
