Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutter mounting structure in an apparatus having cutters closely arranged on one axis, such as a continuous kneading machine for fish and meat.

The above-mentioned continuous kneading machine kneads the fish and meat and the auxiliary raw materials while feeding the fish and meat in the axial direction through cutters, so a large number of cutters are arranged on one axis.

Conventionally, when attaching these cutters to a shaft, a boss-shaped holder for holding each cutter was sequentially fitted onto the shaft from one end of the shaft. For this reason, if one cutter in the middle is damaged, the other cutters that are not damaged must be removed before replacing the damaged cutter, making the replacement work complicated. Since the cutter is simply fixed to the holder, it is not possible to adjust the inclination and protrusion length of the blade of the cutter when the cutter wears.

The present invention eliminates the drawbacks of the conventional cutters, makes it possible to easily replace each cutter individually, and also allows the inclination of the cutter pieces and the protruding length of the tip to be freely adjusted. This was made for the purpose of providing a cutter mounting structure and has cutters arranged densely on one axis, and the cutter is composed of a pair of cutter pieces, and a circle that holds the bases of these cutter pieces. A holder consisting of an annular main and auxiliary holder is each divided into two on its diameter line, a plurality of mounting bolts are provided for attaching the cutter pieces to the holder, and a plurality of cutter attachment holes are inserted into the cutter pieces through which the mounting bolts are inserted. , and these cutter mounting holes are arranged in a virtual arc centered on the center of rotation of the cutter piece, which is provided at a position away from the center of the holder so that the position of the cutting edge of the cutter piece with respect to the center of the holder is variable. The split pieces of the main holder are formed into elongated holes that are long in the tangential direction, and the split pieces of the main holder can be combined with each other and fixed to the shaft, and the bases of the pair of cut pieces are sandwiched between the split pieces of the main and sub holders. This is what I wore.

The present invention will be explained below with reference to embodiments shown in the drawings.

Figures 1 and 2 show the cutter 1 attached to the shaft 2, and the cutter 1 has a pair of cutter pieces 3a and 3b with curved blade parts 4a and 4b protruding toward the outer periphery, respectively. The base portions 5a, 5b of both cutter pieces 3a, 3b are formed with semicircular recesses 6a, 6b that hold the shaft 2 together. In addition, each base 5
A, 5b are formed with a plurality of elongated holes 8, 8, . . ., which are cutter mounting holes, into which mounting bolts 7, 7, . Each long hole 8 in each cutter piece 3a, 3b is
It is formed in the tangential direction of a virtual arc centered on the ends a, b of the bases 5a, 5b of each cutter piece 3a, 3b, and the length of each elongated hole 8 is from the central end a, b. is proportional to the distance. Therefore,
When the bolts 7 are fixed, the cutter pieces 3a and 3b can be rotated in the directions of arrows Aa and Ab about the ends a and b, respectively. Furthermore, each base 5
Approximately triangular notches 9, 9... are formed at both ends of the cutter pieces 3a, 5b to prevent the bases 5a, 5b of the cutter pieces 3a, 3b from overlapping each other. 3b can be mounted eccentrically to the shaft 2 to some extent. Note that the rotation centers of the cutter pieces 3a and 3b are not limited to the ends a and b, and may be at other locations,
The direction of the elongated hole 8 is the tangential direction of a virtual arc centered on the rotation center of the cutter piece provided at a position off the center of the holder, and the length of the elongated hole 8 is determined by the distance from the rotation center. It will be proportional.

The cutter 1 is fixed by a holder 10, and the holder 10 is composed of a main holder 11 and a sub-holder 12 that hold the cutter 1 therebetween.

As shown in detail in FIGS. 3 and 4, the main holder 11 has an annular shape as a whole, and its inner diameter is large enough to fit into the shaft 2 proportionally and closely. This main holder 11 is divided into two parts 13a and 1 on its diameter line.
3b, and one end of each divided piece 13a, 13b has bolt holes 14a, 14 in the tangential direction, respectively.
b is drilled therein, and bolt insertion holes 15a, 15b coaxial with the bolt holes 14b, 14a are drilled in the other ends of each of the divided pieces 13a, 13b. Furthermore, a recess 16 is formed on the surface of each divided piece 13a, 13b on the axial extension of each bolt insertion hole 15a, 15b.
a, 16b are formed, and the bolt insertion hole 15
Bolts 17, 17 can be screwed from a, 15b to bolt holes 14a, 14b. Further, on the surface of each of the divided pieces 13a, 13b on the side where the cutter pieces 3a, 3b come into contact, a plurality of axial bolt holes 18, 18 are provided at positions corresponding to the elongated holes 8 of the cutter pieces 3a, 3b. ... has been drilled. Furthermore, a positioning hole 19 into which a knock pin (not shown) protruding from the shaft 2 can be fitted is bored in the inner circumferential surface of one of the divided pieces 13a. By fitting, the circumferential position of the cutter 1 is regulated. This is because the regular arrangement of a large number of cutters 1 makes it possible for the first time to carry out kneading while conveying the raw materials.

On the other hand, the sub holder 12 is shown in FIGS.
As shown in the figure, it has an annular shape as a whole,
Its inner and outer diameters are approximately equal to the inner and outer diameters of the main holder 11. And this sub-holder 12 also
Like the main holder 11, it is composed of two divided pieces 20a and 20b on its diameter line, and each divided piece 20a and 20b has a plurality of holes at positions corresponding to the bolt holes 18 of the main holder 11. Bolt insertion holes 21, 21... are bored. As shown in FIG. 1, each of these bolt insertion holes 21 is partially formed into a large diameter portion 24 so that a head 23 of a bolt 22 can be inserted therein.

Next, the operation of the above-described embodiment will be explained.

First, one of the cutter pieces 3a is sandwiched between one of the divided pieces 13a of the main holder 11 and one of the divided pieces 20a of the sub-holder 12, and the divided piece 2 of the sub-holder 12
Insert bolts 22 into each bolt insertion hole 21 of 0a.

After passing through each elongated hole 8 of the main holder 11, the main holder 11 is screwed into the bolt hole 18 of the main holder 11. As a result, both divided pieces 13a, 2
A first assembly 2 in which a cutter piece 3a is held between 0a
5a has been formed. Both divided pieces 13
When the cutter piece 3a is held between the cutter pieces 3a and 20a, the cutter piece 3a can rotate around the end a of the cutter piece 3a so that each elongated hole 8 of the cutter piece 3a moves along the bolt 22. Cut piece 3a
The inclination state of the blade portion 4a and the protruding length of the tip of the blade portion 4a can be freely adjusted. The ability to adjust the inclination of the blade and the protruding length of the tip of the blade in this way also applies to other cutter pieces 3b, which will be described later. Therefore, each cutter piece 3a, 3b can be uniformly attached and adjusted to the holder 10 using a jig in advance before attachment to the shaft 2, and a well-balanced arrangement of the cutters 1 can be achieved in a continuous kneading machine. becomes possible. In addition, since the tips of the blades 4a and 4b of the cutter 1 can be brought close to the inner circumferential surface of the casing of the continuous kneader over a long arc range, the meat can be thoroughly stirred, and the inner circumferential surface of the casing Unsanitary leftover meat left behind is also completely eliminated. Furthermore, since the cutter 1 can be adjusted even if it wears out, the life of the cutter 1 is increased.

Then, in the same manner as described above, the main holder 11
The other cutter piece 3b is narrowed by the other divided piece 13b of the sub holder 12 and the other divided piece 20b of the sub holder 12, and both divided pieces 13b, 20b are connected to the plurality of bolts 2.
2, 22... to form a second assembly 25b.

Finally, after holding the shaft 2 by both assemblies 25a and 25b, both divided pieces 13a and 13b of the main holder 11 of both assemblies 25a and 25b are inserted into the bolt hole 1 from the bolt insertion holes 15a and 15b, respectively.
Both assemblies 25a, 25b are fixed to the shaft 2 by screwing the bolts 17, 17 into the assemblies 4b, 14a.

Thus, according to this embodiment, both assemblies 25
a, 25b can be attached to the shaft 2 from the diametrical direction of the shaft 2, and therefore the cutter 1 can be replaced without interfering with other cutters. In addition, each cutter piece 3a, 3b of the cutter 1 from the shaft 2
Since the protruding length and protruding direction of the cutter pieces 3a and 3b can be adjusted freely, the cutter pieces 3a and 3b can be easily adjusted.
The meat can be stirred satisfactorily by extending the tip of 4b in a long arc to be close to the inner circumferential surface of the casing of the kneader.

In the above embodiment, the elongated hole 8 is a linear elongated hole, but it may be an arc-shaped elongated hole.

As explained above, in the cutter mounting structure according to the present invention, the cutter is composed of a pair of cutter pieces, and the holder consisting of the annular main and sub-holders that sandwich the bases of these cutter pieces is attached to the holder along its diameter line. Each piece was divided into two parts, and the divided pieces of the main holder were combined with each other so that they could be fixed to the shaft, and the bases of the pair of cutter pieces were narrowly attached between the divided pieces of the main and sub-holder, so that the holder could be fixed to the shaft. The cutter allows the individual cutter pieces to be easily replaced independently without having to move them along the holder, thereby significantly improving work efficiency, and also allows the cutter pieces to be attached to the holder at a position off the center of the holder. Since the hole is long in the tangential direction of the virtual arc centered on the rotation center of the cutter piece, the direction and length of the protrusion of the cutter piece relative to the holder can be freely adjusted, and the blade of the cutter piece can be moved along the arc. Since they can be placed close to each other over a long range on the inner circumferential surface of the casing, the excellent effect is that the best cutting conditions can always be obtained. Note that the elongated hole 8 described in the embodiment may be a round hole.
