The present invention relates to a cutting blade mounting device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a cutting blade mounting device of the type described above is known. That is, an arm 52 provided on the back side of the cutting plate 51 on which the ice is placed supports the central portion of the blade mounting tool 53, and an adjustment bolt 55 is screwed into a support 54 also provided on the back side of the cutting plate 51. To allow the adjustment bolt 55 to move forward and backward,
Further, the blade mounting tool 53 locked to the adjustment bolt 55 by rotating the adjustment bolt 55
Is rotated, and the cutting edge 57 of the cutting blade 56 fixed to the tip of the blade mounting tool 53 is moved to the cutting plate 5.
An ice cutter capable of protruding from the upper surface 59 of the cutting plate 51 to a predetermined height through the through hole 58 provided in No. 1 is known (Japanese Utility Model Laid-Open No. 53-43079). In this apparatus, the cutting edge 56 of the cutting blade 56 is
The excellent effect that the height protruding from 9 can be finely adjusted is exhibited.

However, it has been found that when this apparatus is used to roughly cut an ice block to obtain coarse shaved ice, the roughness varies. When the cause was investigated, it was found that the device had a mechanical problem. That is, in order to obtain coarse cutting ice, when the adjusting bolt 55 is screwed against the compressive force of the coil spring 60 externally mounted near the tip of the adjusting bolt 55, the adjusting bolt 55 is inclined with the inclination angle α. The cutting blade 56 rises, and the inclination angle becomes larger (becomes the inclination angle β). Then, the cutting resistance applied to the cutting blade 56 increases, and the cutting tool attachment 53 rotates in a direction in which the cutting blade 56 rises up more in a range where the repulsive force of the coil spring 60 is balanced.

As a result, not only does the size of the cut ice grains vary, but in some cases, ice blocks on the cutting plate 51 are chipped. An object of the present invention is to provide an ice-milling machine of the type described above, in which even if a cutting load is suddenly applied to the cutting edge of the cutting blade, the cutting edge does not rise more than the amount of protrusion adjusted from the upper surface of the cutting plate, so that The purpose of the present invention is to prevent variations in the roughness of the ice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1, 2 and 3. In an ice cutter according to the present invention, a back surface 3 of a cutting plate 1 on which ice is placed. The cutting blade mounting device C having the structure described below is fixed to the mounting seat 4 formed in the above. That is, a support 10 having a substantially Y-shaped planar shape is fixed to the mounting seat 4 by the screw 11 at the center thereof. A blade mounting member 13 for mounting a cutting blade 15 is rotatably mounted between a pair of arms 12 branched on the distal end side of the support 10.

[0007] A cutting blade 15 for cutting ice is fixed to a tip piece 14 of the blade mounting fixture 13 with a screw 17. Similarly, a through hole 21 is formed in the base end piece of the blade mounting fixture 13, and the periphery of the through hole 21 is a seat portion 22 which is surrounded by a semi-annular protrusion 20 and into which a coil spring described below is dropped. I have. In addition, by passing a pin 24 in common through a boss hole 19 of a boss 18 formed in the center of the blade attachment 13 and the pair of arms 12, the blade attachment 13 is centered on the pin 24. It is designed to rotate.

On the other hand, one female screw 32 is threaded on the rear end side of the support 10 (see FIG. 2), and the knife mounting member 13 is locked / turned with respect to the female screw 32. One adjusting bolt 25 for moving is screwable.
In the adjusting bolt 25, a knob 30 is fixed to a base end by a pin 31 functioning as a second stopper described later, and a female screw 32 of the support 10 is fixed to a distal end.
A male screw 26 is screwed into the flange 26, and a flange member 27 as a first stopper is further fixed in the middle.

In order to assemble the cutting blade mounting device C by mounting the blade mounting member 13 and the adjustment bolt 25 to the support 10, first, the coil spring 23 is dropped into the seat portion 22 of the blade mounting member 13, and The washer 28 is placed on the upper part, and the adjusting bolt 25 in a state where the knob 30 is not yet attached is inserted from the base end of the adjusting bolt 25 into the through-hole 21 of the blade fixture 13.
Insert

Next, the washer 29 and the knob 30 are sequentially extrapolated to the adjusting bolt 25, and then the knob 30 and the adjusting bolt 25 are extrapolated.
The pin 31 is inserted in common to integrate the two, and the blade mount 13 is sandwiched between the coil spring 23 and the washer 29.

Subsequently, the female screw 32 of the support 10 is fitted to the male screw 26 of the adjusting bolt 25, and the two are slightly screwed together to temporarily fix them. The cutting tool 15 and the support 10 are fixed in advance. Arm 12 is pinned via a pin 24. Then, fully tighten the adjustment bolt 25,
In this case, the male screw 26 and the female screw 32 are not completely screwed together, but are fully tightened with some room for screwing.

In the cutting blade mounting apparatus C assembled in this manner, the support 10 is fixed to the mounting seat 4 of the cutting plate 1 with screws 11 and the cutting blade 15 is fixed between the through holes 2 of the cutting plate 1. By facing upward from
It can be mounted on ice machines.

Next, the operation and effect of the apparatus according to the present invention will be described. First, the cutting edge 16 of the cutting blade 15 is slightly protruded from the upper surface of the cutting plate 1 so as to obtain finer cutting ice. In this case, the knob 30 is rotated to advance the adjustment bolt 25 toward the cutting plate 1. Then, since the blade mount 13 rotates about the pin 24 of the arm 12, the cutting edge 16 of the cutting blade 15 rotates in a direction to reduce the protruding amount.

On the other hand, when it is desired to obtain cutting ice having a coarser cut, the adjusting bolt 25 is retracted in a direction away from the cutting plate 1, contrary to the above operation. Then, the blade mount 13 rotates in a rising direction, and the cutting edge 16 of the cutting blade 15 rotates in a direction to increase the protruding amount.

The above operation is the same as that of the prior art. However, in the apparatus of the present invention, unlike the prior art, a coil spring 23 is provided on the knob 30 side of the adjustment bolt 25 at the base end of the blade mounting fixture 13. Without adjusting bolt 25
Since the pin 31 is common to the knob 30 and the pin, the base end of the blade attachment 13 is prevented from being displaced away from the cutting plate 10 while being urged by the coil spring 23.

Therefore, even if an excessive cutting load is applied to the cutting edge 16 of the cutting blade 15 protruding from the upper surface of the cutting plate 1, the cutting edge 16 does not rotate further up. In this sense, the pin 31 as the second stopper functions as a stopper that prevents the blade attachment 13 from rotating in the direction opposite to the direction in which the clock hand rotates in FIG. Further, since the flange-shaped member 27 as the first stopper is integrally fixed to the adjustment bolt 25, even if the adjustment bolt 25 is retracted from the support 10, the coil spring 23 does not extend. In this sense, the collar member 27 functions as an extension stopper for the coil spring.

Conversely, if the coil spring 23 is extrapolated to the adjusting bolt 25 while still being compressible, the downward component force of the ice block placed on the cutting plate 1, that is, the tip 16 is held down. A component force is applied to the cutting blade 15,
As a result, the blade mount 13 tends to rotate in a direction that reduces the amount of protrusion of the blade edge 16. However, at that time, the repulsive force of the coil spring 23 increases, so that, as in the related art, an appropriately fine cut ice can be obtained by adjusting the advance / retreat position of the adjusting bolt 25.

[0018]

As described above in detail, according to the present invention, even when a cutting load is suddenly applied to the cutting edge of the cutting blade, the cutting edge never rises beyond the protrusion amount adjusted from the upper surface of the cutting plate. An excellent effect of suppressing variation in the roughness of shaved ice is exhibited.
