Description

[Detailed description of the invention] The present invention is an ice cutting machine that enables timely switching between cutting small ice blocks into snowflake shapes and crushing ice.
In a device that cuts and discharges small ice cubes supplied to a cutting case using a cutting blade that is rotated by a rotating body in the case and protrudes from the discharge port of the case, the cutting blade and the ice-breaking blade are combined. are slidably stacked one on top of the other, and either one of the blades is selectively protruded into the cutting case from the outside of the outlet, and when cutting the cutting blade projects into the case, the blade block of the blade is When crushing ice, the ice-breaking blade comes into contact with the blade guide of the holder base and protrudes into the case, by fixing the blade block of the blade in contact with the support plate of the holder base.
The object is to obtain shaved ice or crushed ice of uniform size and uniform quality by always keeping the degree of protrusion constant when changing the position of each blade protruding into the cutting case.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a machine frame in which a known type of inverted conical cutting case 3 is fixed. A rotary blade 5 that rotates with a certain gap is fixed to the inner wall surface. A cylindrical hopper 7 is fixed to the upper part of the rotating blade 5.

A discharge port 8 is provided on the peripheral surface of the cutting case 3, and a mounting seat 9 is integrally provided on the outside of the peripheral surface of the discharge port 8 located on the rear side in the rotational direction of the rotating blade 5. Reference numeral 10 denotes a support piece attached to the mounting seat 9 with screws 11, and is provided with a first arm 12 and a second arm 13 that protrude outward from both sides (FIGS. 8 and 9). Reference numeral 15 denotes a holder base, and as shown in FIGS. 2 and 3, a known protrusion adjustment lever 18 is provided on the rear surface of a plate-shaped base plate 16, and a shaft pin 37 at the tip of the first arm is attached to the base of the lever 18. A shaft hole 17 to be fitted is provided. A shaft pin 37 is inserted into the shaft hole 17 on the front surface of the base plate 16 as shown in FIGS. Each rod-shaped support plate 20 is provided at the opposite position, and a switching rod insertion hole 21 is formed in the latter. The base plate 16 is provided with a guide groove 23 for an ice-breaking blade.

Reference numeral 24 denotes a cutting blade which fits freely into the guide groove 23 of the cutting blade, and has a blade block 25 which protrudes at a right angle from its rear end, and a screw hole 26 which is aligned with the axis of the insertion hole 21 is provided in the block 25 (FIGS. 4 and 5).

Reference numeral 27 denotes an ice-breaking blade which is slidably superimposed on the back of the cutting blade 24 and slidably fitted into the guide groove 23, and is provided with a comb-shaped ice-breaking blade 28 at its tip. A cutter block 30 projecting at right angles is provided at the rear end of the ice-breaking cutter 27, and an insertion hole 2 is provided in the block 30.
1. A screw hole 31 is formed that is aligned with the axis of 1. (Figures 6-9).

Reference numeral 32 denotes a switching rod, which has a reduced diameter portion 33 provided at the center in the longitudinal direction, which is freely rotated through the insertion hole 21, and fixed in position by a screw 36.
For example, there is a rightward first
A feed screw 34 is provided, a second feed screw 35 is provided rearward and leftward from the reduced diameter portion 33, and a first feed screw 34 is provided.
is screwed into the screw hole 26 provided in the blade block 25 of the cutting blade 24, and the second feed screw 35 is inserted into the ice-breaking blade 27.
It is screwed into a screw hole 31 provided in a cutter block 30.

The cutting blade 24, the ice-breaking blade 27, and the switching rod 32 are assembled into a block shape using the base plate 16.
The front surface 25a of the cutter block 25 of the cutting tool 24 is connected to the rear surface 19a of the cutter guide 19 of the holder base 15.
The front surface 30a of the cutter block 30 of the ice-breaking cutter 27 is made to correspond to the rear surface 20a of the support plate 20 of the base 15, and the holder base 1
5 is attached to the support piece 10 by a shaft pin 37. At this time, the protrusion adjustment lever 18 corresponds to a cam 38 rotatably provided on the second arm 13, and a spring 39 is provided between the lever 18 and the support piece 10 to press the lever 18 against the cam 38. (Figures 8 and 9). In the above structure, when the switching rod 32 is rotated clockwise, the cutting blade 24 is projected into the case from the outlet 8 of the cutting case 3 by the first feed screw 34, and at the same time, the ice-breaking blade 27 is moved by the second feed screw 35.
The front face 25a of the blade block 25 of the cutting blade 24 and the holder base 15
The rear surface 19a of the blade guide 19 is integrally abutted and fixed, and the cutting edge of the cutting blade 24 protruding into the cutting case 3 is held parallel to the inner circumference of the case 3 (Fig. 8). ). Further, when the switching rod 32 is rotated counterclockwise, the cutting blade 24 is retracted from the discharge port 8 to the outside of the case, the ice-breaking blade 27 is projected into the interior of the cutting case 3, and the front face 30a of the blade block 30 of the ice-breaking blade 27 and the holder base are moved. 15 and the rear surface 20a of the support plate 20 are integrally abutted and fixed, and the cutting edge of the ice-breaking knife 27 is held parallel to the inner circumference of the case 3 in the same manner as described above (FIG. 9). The degree of protrusion of the cutting blade 24 shown in FIG. 8 and the degree of protrusion of the ice-breaking blade 27 shown in FIG. 9 are adjusted by rotating the cam.

The ice cutting and ice crushing machine of the present invention can also be of a type in which the cutting case has a flat bottom and the double-edged tool is attached to the bottom.

The present invention has the structure and operation described in the above embodiment, and the cutting blade 24 and the ice-breaking blade 27 are fitted into the blade guide 19 formed on the holder base 15 so as to be able to slide freely overlapping each other. The cutter block 25 of the cutting blade 24 is attached to a first feed screw 34 formed on a switching rod 32 rotatably supported on the support plate 20, and the cutter block 25 of the cutting blade 24 is attached to a second feed screw 35 formed with the thread direction opposite to that of the first feed screw 34. The blade blocks 30 of the ice-breaking blades 27 are engaged with each other, and the cutting blade and the ice-breaking blade are alternately projected into the cutting case by switching the rotational direction of the switching rod 32. The cutter block and the cutter guide of the holder base are integrally brought into contact with each other, and when the ice-breaking knife is protruded, the cutter block of the ice-breaker knife and the support plate of the base are brought into contact with each other as one body to fix these blades. Therefore, while one blade is working, the other blade is not involved at all, and once the parallelism of the blade edges of each blade is adjusted, even if the two blades are repeatedly protruded and retracted by the switching rod, each blade edge will always remain the same. Not only is the parallelism maintained, but even if the load changes during operation, the parallelism will not be impaired due to the integral contact between the cutter block of each cutter and the cutter guide or support plate of the holder base. From this, it is possible to obtain uniform shaved or crushed ice of uniform size and quality.
