DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a bristle flocking brush roll for polishing steel industry strips,
The present invention relates to a cooling method and a cooling device for cooling a brush roll of a specification using cooling water from inside the brush roll. Here, the bristle flocking type brush roll is a method in which a large number of annular discs in which bristles containing abrasives such as abrasive grains are planted or flocked on the outer peripheral portion are fitted to the roll shaft, that is, mounted in a manner parallel to the length direction of the roll shaft. Brush rolls. This is the case throughout this specification. The roll shaft is hollow, and cooling water is supplied to the hollow, which reaches a bristle on the disk through a water passage opening in the peripheral surface of the roll shaft, and cools it.

[0002] This kind of cooling type brush roll is suitable for operation at high speed rotation, and is widely used for polishing of strip in the steelmaking industry.

2. Description of the Related Art Conventionally, in a brush roll of a bristle flocking type, in which cooling is performed by cooling water from the inside, a group surrounded by bristle bundles, ie, a region without a bristle, is included in a group of bristle bundles planted. The hatched parallel part in Fig. 5. This figure is a view of the bristle implanted in the annular disk viewed from the rooted side of the bristle, where the circular and almost circular portions are bristle, and the elongated narrow space extending horizontally is annular. Disc is shown) is applied to a water passage from the water passage opening on the peripheral surface of the roll shaft to the bristle bundle.

[0004]

In the prior art described above, the area which is a water passage from the water opening on the peripheral surface of the roll shaft to the bristle is, as shown in FIG. 5, the area occupied by the bundle of the flocking bristle. They are almost the same size. In a water passage that spreads in such a size, the water in the water passage easily scatters outside due to rotation of the brush roll. For this reason, water is not accurately supplied to the bristles bundle, and the cooling results of the bristles are inevitably deteriorated. In addition, the supply of cooling water is unbalanced for the entire bristles in the brush roll. If the water supply to the entire bristle is unbalanced, the temperature rise due to friction will be uneven for the entire bristle flocking group, unevenness will occur in the polishing of the strip, the bristle in the zone with poor cooling effect will break, and the temperature rises Or wear. The present invention solves such a problem, that is, it can distribute the cooling water evenly over the bristle flocked area of the brush roll, and can supply the cooling water substantially to one of the bristles bundles, and provide an even distribution of the cooling water. The task is to be able to perform it stably.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a brush roll of a bristle flocking type in which cooling is performed by cooling water from the inside of the brush roll. A water-passing member extending substantially over the entire circumference of the annular disk is provided inside the bristle, and one end of the water-passing member communicates with a water-flow opening on the peripheral surface of the roll shaft, and the other end of the water-permeable member has a bristle bundle of the annular disk. A narrow water channel leading to the root is formed, and the water channel is arranged substantially corresponding to the bristle bundle in each annular disk of the brush roll. The water passage groove is a water passage from the water passage opening on the peripheral surface of the roll shaft to the bristle bundle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described together with examples with reference to the drawings. In the figure, reference numeral 1 denotes a brush roll for polishing a strip in the steelmaking industry. As the brush roll 1 may be the same as the conventional one, only an outline is shown in FIG. 9 (FIG. 9). The brush roll 1 is an annular disk 3 in which a bristle 2 is implanted or flocked on the outer periphery.
(FIG. 1). The bristle 2 has a monofilament yarn or a plurality of parallel aggregates of monofilament yarns as an element. The bent end portions are bound by a binding body 4 such as a wire, and are implanted or implanted in the disk 3. The U-shaped bending of the bristle element is performed by
Turn (see FIG. 3). In the case shown, Bristle 2
Is a bundle of three elements. A large number of disks 3 on which bristles 2 are implanted are mounted so as to be fitted on the roll shaft 5, that is, arranged in parallel in the length direction of the roll shaft 5.

Each of the annular disks 3 arranged in parallel on the roll shaft 5 is provided with a water passage member 6 inside the respective bristles 2. The water-passing member 6 includes the annular disks 3 and 3 arranged in parallel.
Sandwiched between The water passing member 6 extends over substantially the entire circumference of the annular disk 3. In the case shown,
The water-passing member 6 is a piece (see FIG. 6) corresponding to dividing the entire circumference of the disk 3 into an appropriate number, and by arranging the required number thereof in a circle, the entire circumference of the disk 3 is formed. It is shaped to extend.

The six pieces of water-permeable members arranged in the circumferential direction of the annular disc 3 are fitted by a projection 7 formed at a fixed position at one end of the piece and a concave portion 8 formed at a fixed position at the other end. ,
The pieces of the water-passing member 6, which are arranged in the radial direction of the disc 3 and are arranged in the parallel direction of the disc 3 (the length direction of the roll shaft 5), have a projection 9 formed at a fixed position on one side of the front and back, and other By being fitted to the concave portion 10 formed at a fixed position on one side of the disk 3, the arrangement of the disks 3 in the parallel direction (the length direction of the roll shaft 5) is maintained.

In the illustrated example, the outer periphery of the water-permeable member 6 (around the bristle 2 side) is formed by the two water-permeable members 6 adjacent to each other in the longitudinal direction of the roll shaft 5 under the intervention of the disk 3. The portion corresponding to the root of the bundle of bristles 2 is a concave portion 12 for receiving the root, and portions corresponding to the front, rear, left, and right sides of the root of the bristle 2 bundle surround the concave portion 12 and The protrusion 13 protrudes toward the opposite side of the center.

In the six-piece water-permeable member, the water-permeable groove 11 is located at a position corresponding to each of the bundles of the bristle 2 in each annular disk 3 or the absolute majority of the bundle of the bristle 2, that is, substantially each of the bundles of the bristle. It is formed as follows. The water passage groove 11 has a small cross-sectional area, one end of which communicates with a water passage opening (not shown) on the peripheral surface of the roll shaft 5, and the other end of which communicates with the root of the bundle of bristles 2 in the disk 3. It is preferable that the other end of the water passage groove 11 communicates with the root near the root portion of the bristles 2 bundle, and when the outer periphery of the water passage member 6 is in the above-described mode, it is more preferable that the bottom of the concave recess 12 is formed. In the central region of the bristles.

The water passage groove 11 forms a water passage from the water passage opening on the peripheral surface of the roll shaft 5 to the bristle bundle. The cooling water supplied to the hollow portion (not shown) of the roll shaft 5 is supplied to a water-permeable member 6
Are supplied to each of the two bundles of bristles in each annular disk 3 through the water passage grooves 11 to cool the bristles. In this case, since the water passage groove 11 of the water passage member 6 is located at a position substantially corresponding to each of the two bundles of bristles in each annular disk 3, the water passage member 6 extends over substantially the entire circumference of the annular disk 3. In addition, the cooling water can be evenly distributed over the entire bristle 2 flocking area of the brush roll 1, and the cooling water can be supplied to substantially one bundle of the bristle 2.

The small cross-sectional area of the water passage groove 11 acts as a throttle valve for restricting the flow of the cooling water, thereby stabilizing the uniform distribution of the cooling water. When the end on the bristle bundle root portion side (the other end in the above description) of the water passage groove 11 is close to the bristle bundle root portion and communicates with the root portion, the uniform distribution of the cooling water and the stability thereof are further improved. When the end of the water passage groove 11 communicates with the root portion of the bristle bundle in the central region, the water supply to the root portion of the bristle bundle is concentrated, and the water supply result of the cooling water is improved.

The outer periphery of the water-passing member 6 is as shown in the embodiment shown in the drawing, that is, the two water-passing members 6 adjacent to each other in the longitudinal direction of the roll shaft 5 are joined to form a portion corresponding to the root of the bristle bundle. When the recessed portion 12 for receiving the root portion has portions corresponding to the front, rear, left, and right sides of the bristle bundle root portion, and the projection 13 protrudes toward the opposite center side of the disc 3 around the recessed portion 12, The distribution and supply of the cooling water to the bristle bundle root becomes more intensive, and the uniform distribution of the cooling water and its stability are better. When the end of the water passage groove 11 on the bristle bundle root side communicates with the bristle bundle root in the central region of the bottom of the concave portion 12, the uniform distribution of cooling water and the stability thereof are further improved.
