Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a raw seaweed cutting device used for cutting raw seaweed.

[Conventional technology]

Conventional raw seaweed cutting equipment has a rotary blade installed on the back side of a fixed blade, and a screw conveyor pushes the native seaweed toward the fixed blade. This original seaweed was cut by rotation.

If you want to change the size of the seaweed to be cut, use the required number of fixed blades (with different hole diameters) and the required number of rotating blades (with different numbers of blades).
The cutting work was performed by preparing a fixed blade and a rotating blade in appropriate combinations.

[Problems with conventional technology]

However, in such conventional cutting devices, the ratio between the rotation speed of the screw conveyor and the rotation speed of the rotary blade was constant, so when adjusting the size of raw seaweed to be cut, We have to rely on the selection of fixed blades (different hole diameters) and rotary blades (different number of blades), and as a result,
Fine adjustment of the size of raw seaweed to be cut was almost impossible.

Furthermore, with such conventional cutting devices, when adjusting the size of the seaweed to be cut, the device must be stopped and the rotary blade and fixed blade replaced each time, which reduces work efficiency. This had the inconvenience of having to decline.

[Means for solving problems]

This invention was made to eliminate the above-mentioned inconvenience, and its structure consists of a transfer tube, a support shaft with screw blades protruding from the side, a disk-shaped fixed blade with a through hole, and a rotating blade. a rotary blade fixed around a shaft, the support shaft of the screw blade is rotatably installed in the transfer cylinder with the same axial direction, and the fixed blade covers one end opening of the transfer cylinder, Furthermore, the rotary blade is rotatably installed along a side surface of the fixed blade, a shaft hole is formed in the support shaft of the screw blade, and the rotary shaft of the rotary blade is rotatably inserted through the shaft hole. and by rotating the spindle, the screw blades operate to transfer the native seaweed in the transfer tube toward the fixed blade, and the native seaweed is drawn to the inner end of the through hole of the fixed blade. In the raw seaweed cutting device that cuts the native seaweed by the rotation of the rotary blade when the seaweed is caught, the inner diameter of the transfer tube and the outer diameter of the screw blade are expanded in the transfer direction, and The rotary blade is arranged inside the fixed blade, and a rotation speed adjusting means is provided on at least one of the support shaft and the rotation shaft, so that the rotation speed of at least one of the support shaft and the rotation shaft can be adjusted as appropriate. This is a raw seaweed cutting device that is characterized by:

[Effect of invention]

Since the raw seaweed cutting device according to this invention is configured as described above, that is, the inner diameter of the transfer cylinder and the outer diameter of the screw blade are enlarged as they move toward the transfer direction.
The native seaweed can be transferred without applying pressure in the direction of the fixed blade, and since the rotary blade is arranged inside the fixed blade, the native seaweed can be cut. A rotation speed adjusting means is provided on at least one of the spindles, so that the rotation speed of at least one of the support shaft and the rotation shaft can be adjusted appropriately, so that the rotation speed of the screw conveyor and the rotation speed of the rotary blade can be adjusted. The rotation speed of at least one of the two can be adjusted. Therefore, by adjusting the rotational speed of the screw blade, the rate at which the native seaweed is fed toward the fixed blade, and by adjusting the rotational speed of the rotary blade, the rate at which the native seaweed enters the hole of the fixed blade ( ) in the native seaweed caught on the inner edge of the through hole, and in turn the interval at which the native seaweed is cut can be adjusted.

[Explanation of Examples]

Examples of this invention will be described below based on the drawings.

In FIG. 4, 11 is a raw seaweed cutting device, which is fixed to the upper part of the frame F. This seaweed cutting device 11 cuts the native seaweed M supplied from the hopper 13 into appropriate sizes and discharges it into the cleaning tank 15. Native seaweed M washed in this washing tank 15
is sent to the next process via the transfer pipe 17. Note that 19 is a transfer pump installed in the middle of the transfer pipe 17. Further, 21 and 23 are electric motors,
The rotational power of these electric motors 21 and 23 is transmitted through the reducer 2
5, 27 to drive the cutting device 11.

Next, the raw seaweed cutting device 11 will be described in detail based on FIGS. 1 to 3.

31 is a truncated cone-shaped transfer tube, and 33 is this transfer tube 3.
This is an auxiliary cylinder integrally formed on the upper part of 1. This auxiliary cylinder 33 is connected to the hopper 13, and is connected to the native seaweed M.
is supplied into the transfer cylinder 31.

35 is a support shaft, and a bearing 3 is installed in the transfer cylinder 31.
It is installed via 7. The axis of this support shaft 35 is the same as the axis of the transfer cylinder 31. A sprocket 39 is fitted onto the protruding end of the support shaft 35. This sprocket 39 is the reducer 2
5 through a chain 41 (see FIG. 4). Therefore, the rotational force of the electric motor 21 is transmitted to the support shaft 35 in a decelerated state. Further, 43 is a screw blade, which is integrally formed on the side surface of the support shaft 35. The screw blades 43 are in contact with the inner wall surface of the transfer tube 31, and the rotation of the support shaft 35 transfers the native seaweed M toward the large opening 45 of the transfer tube 31.

Next, 51 is a rotating shaft, which is rotatably installed in the shaft hole 53 of the support shaft 35 via bearings 55, 55. This rotating shaft 51 passes through the shaft hole 53 of the support shaft 35, and its axis is the same as that of the support shaft 35. 57 is a sprocket, which is located at the protruding end of the rotating shaft 51 (on the right side in FIG. 1).
is attached to. This sprocket 57 is connected to the reducer 27 via a chain 59 (see FIG. 4). Therefore, the rotational force of the electric motor 23 is transmitted to the rotating shaft 51 in a decelerated state. 61
is an auxiliary shaft portion, and the large opening 45 of the rotating shaft 51
It is integrally formed at the end. The cross section of this auxiliary shaft portion 61 is square. Further, reference numeral 63 denotes a rotary blade, which is externally fitted onto the auxiliary shaft portion 61 through its center hole 65 (see FIG. 2) without any gap. Here, since the cross section of this auxiliary shaft portion 61 and the inner periphery of the center hole 65 of the rotary blade 63 are square,
The rotary blade 63 always rotates integrally with the auxiliary shaft portion 61.

Reference numeral 71 denotes a disk-shaped fixed blade, which covers the large opening 45 of the transfer tube 31. As shown in FIG. 3, this fixed blade 71 has a support hole 73 at the center and a required number of through holes 75 at the ends. Here, the support hole 73
The auxiliary shaft portion 61 of the rotating shaft 51 is rotatably fitted into the shaft via an intervening tube 77. This intervening cylinder 7
7 has an inner wall surface having a quadrangular cross section and an outer wall surface having a perfect circular cross section, so that it rotates as the auxiliary shaft portion 61 rotates. Further, the through holes 75, 75 of the fixed blade 71 are places through which the native seaweed M passes.
A tightening ring 79 is screwed onto the edge of the transfer cylinder 31. This tightening ring 79 tightens and fixes the fixed blade 71 to the transfer tube 31. In addition, 81 is a pin, and the large opening 45 of the transfer cylinder 31
A notch 71a of the fixed blade 71 protrudes from the end.
is fitted. Therefore, the fixed blade 71 cannot rotate in the circumferential direction.

To operate the raw seaweed cutting device 11 configured as described above, first, by driving each electric motor 21, 23, each reducer 25, 27, chain 4
1, 59, the support shaft 35 and the rotating shaft 51 are rotated via the sprockets 39, 57. Support shaft 35
rotates, the screw blade 43 rotates and operates, and as a result, the native seaweed M is transferred in the direction of the fixed blade 71 and attempts to pass through the through holes 75, 75, . . . of the fixed blade 71, as shown in FIG. , through holes 75, 74,...
It gets caught on the inside edge of... In this case, native seaweed M
A part of the holes 75, 74, . . . have penetrated into the holes (see FIG. 5). In this state, the rotary blade 63 rotates as the rotary shaft 51 rotates, so the native seaweed M caught in the through holes 75, 75, . As a result, some of the native seaweed M that was cut at the end and had entered the through holes 75, 74, . . .
It passes through and is discharged to the outside.

By changing the rotational speed of the support shaft 35, the transport speed of the native seaweed changes, so the rate of penetration of the native seaweed M into the through hole (of the fixed blade 71) 75 (the rate at which the native seaweed M is caught on the inner edge of the through hole) is increased. ) in the native seaweed changes, so even if the rotational speed of the rotary blade 63 is constant, the size of the native seaweed M that is cut varies.

Furthermore, if the rotational speed of the rotating shaft 51 is changed, the time interval at which the rotary blade 63 cuts the native seaweed M changes, so the rate at which the native seaweed M enters the through hole (of the fixed blade 71) 75 changes. (in the native seaweed caught on the inner edge of the hole) changes,
Even if the rotational speed of the support shaft 35 is constant, the size of the native seaweed M to be cut varies. Note that by changing the rotational speed of the support shaft 35 and the rotating shaft 51, the size of the native seaweed M that is cut will be finer than when only one of these 35 and 51 is changed as described above. You can adjust the height.
