Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heavy-duty brush roll, and more particularly, to a brush bristle, which includes a polishing tip having abrasive grains bonded with a binder and a spring rod having the tip thereof bonded to the tip to thereby provide a substantially grinding surface. However, the present invention relates to a brush roll having a polishing performance comparable to or close to that of a polishing disc.

In such a heavy-duty brush roll, the bristles are attached in parallel to the outer peripheral edge of a fan-shaped board-shaped segment that extends at an angle, and the segment is attached to the roll axis and a circle around the axis. The brush discs formed by the circular parallel bodies of the segments are mounted on the roll shaft from the peripheral surface of the roll by being configured to be mounted at the root portions of the segments while being in contact with each other in the lengthwise direction.
It is advantageous that it can be removed, the axial restraint can be released, and the segment in a partial area can be easily removed and newly attached.

[0003]

2. Description of the Related Art Conventionally, such a heavy polishing brush roll is already known. However, the polishing ability is strong enough,
Moreover, in order to bring the disc segments into the required restraint state in the roll axial direction, they must be brought into contact with each other in the roll axial direction.Thus, cooling water is passed from the water passage groove on the circumferential surface of the roll shaft to the root of the disc segments. However, the bristle's polishing tip is hard to be cooled by water, and in continuous operation, the polishing tip is burned by frictional heat, and there is a problem that the service life is not very long.

[0004]

The problem to be solved is to solve the above problems.

[0005]

In order to solve the above-mentioned problems, the present invention has a brush bristle including an abrasive tip having abrasive grains bonded with a binder and a spring rod having the tip thereof bonded to the outer peripheral edge in parallel. The fan-shaped board-shaped segments provided are mounted on the peripheral surface of the roll shaft at the mounting portion at the base of the segment under the condition that they are arranged in a circle around the shaft and are densely packed in the longitudinal direction. In a heavy-duty brush roll having a cooling water passage groove opened at the base of the segment, the front and rear surfaces of the left and right side end portions of the segment attachment portion are in contact with each other or adjacent to each other in the roll axial length direction. It is characterized in that a ridge is formed so as to be close to and extend substantially along the side edge of the end.

According to the present invention, in the heavy-duty brush roll having the above-mentioned structure, grooves which are opened in the radial direction of the roll shaft and arranged in parallel in the circumferential direction are formed on at least one of the front and rear surfaces of the region other than the mounting portion of the segment. The configuration described above may be added.

[0007]

The present invention will now be described with reference to the drawings showing the embodiments of the present invention.

In FIG. 1, reference numeral 1 denotes a brush bristle, and the brush bristle 1 includes a polishing tip 11 having abrasive grains bonded with a binder and a spring rod 12 having the tip thereof bonded to the tip. Reference numeral 13 is a sleeve for connecting the polishing tip 11 and the rod 12.

The brush bristles 1 are planted side by side in the fan-shaped developing direction on the outer peripheral edge of the fan-shaped board-shaped segment 14 at an angle corresponding to an appropriate number of circles of the circumference of the roll shaft 2. The segments 14 are arranged on the circumferential surface of the roll shaft 2 in a circular shape in the circumferential direction of the shaft 2 and are densely packed in the length direction, and are mounted by a mounting portion 15 at the base of the segment 14. The mounting of the segment 14 on the roll shaft 2 is performed by the mounting portion 15
Is a dovetail type key, and a dovetail type key groove 21 is formed on the circumferential surface of the roll shaft 2 so that the key and the key groove are engaged.

On the peripheral surface of the roll shaft 2 (strictly speaking, the bottom of the key groove 21), a water passage groove 22 which opens to the base of the segment 14 is formed.
Are formed to extend in the length direction of the shaft 2. The water passage 2
2 is designed so that the water is guided substantially evenly in the length and width directions of the groove 22 by a water basin 3 known per se.

On the front and rear surfaces of the left and right end portions of the segment mounting portion 15, there are provided ridges 16 which are in contact with or close to each other adjacent to each other in the length direction of the roll shaft 2. It is formed by extending along. Segment 1
In regions other than the mounting portion 15 of 4, the grooves 17 that open in the radial direction of the roll shaft 2 and that are parallel to the circumferential direction may be formed on at least one of the front and rear surfaces thereof.

In the illustrated embodiment, the region other than the mounting portion 15 is made slightly thicker than the mounting portion 15, and the regions are brought into mutual contact in the length direction of the roll shaft 2 so that the segments 14 are brought into a required dense state. However, instead of this, the ridges 16, 16 adjacent to each other in the length direction of the roll shaft 2 may be brought into mutual contact.

According to the present invention, the fan-shaped board-shaped segment 14 having the parallel body of the bristles 1 on the outer peripheral edge thereof, which is mounted on the peripheral surface of the roll shaft 2 in a predetermined manner, has the mounting portion 15 at the base thereof and the left and right end portions. The ridges 16 are formed on the front and rear surfaces of the. Since the ridges 16 are in contact with or close to each other between the adjacent segments 14 in the lengthwise direction of the roll shaft 2 and extend substantially along the side edge of the end,
It serves as a weir that allows water to flow from the water flow groove 22 on the circumferential surface of the roll shaft to the root of the segment 14 over almost the entire circumference of the root of the roll shaft in the circumferential direction.

Thus, in the present invention, the effect that the polishing tip 11 of the bristle 1 of the segment 14 is cooled by the cooling water from the water passage 22 is improved, and the friction of the polishing tip in continuous operation found in the prior art is improved. Eliminates heat damage and extends service life. This effect is to form the grooves 17 aligned in the coaxial circumferential direction on at least one of the front and rear surfaces of the area other than the attachment portion 15 of the segment 14 so that adjacent ones in the roll axial length direction are in contact with or close to each other. The segment 14 on the outer peripheral side of the mounting portion 15
The migration of water to the area is also improved, and thus improved.

[0015]

As described above, according to the present invention, it is an object of the heavy-duty brush roll of the type described at the beginning to avoid the abrasive tips from being damaged by frictional heat during continuous operation and to extend the service life. A solution is achieved.
