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 roll having a grinding performance which is almost equal to or close to that of a grinding disc.

[0002]

2. Description of the Related Art Recently, such a heavy polishing brush roll has been developed. The grinding element therein is a rod-shaped body containing abrasive grains and a spring material having the grains bonded thereto, and the rod-shaped body has a relatively large diameter. For this reason, when they are arranged on a plane perpendicular to the roll axis, even if they are arranged in a staggered manner, polishing and grinding streaks occur on the plate surface at a certain interval in the axial direction, and There was a problem of lack of uniformity.

[0003]

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

[0004]

In order to solve the above-mentioned problems, the present invention is directed to a rod-shaped body containing abrasive grains having a diameter of 3 mm or more, which is arranged on a roll shaft through a spring member and radially with respect to the circumference of the shaft. In a heavy-duty brush roll that is installed in a state of being gathered in the axial direction, the rod-shaped body and the grinding element body formed by the spring material coupled to the bar-shaped body are arranged in a spiral shape, and the surface in the roll axis length direction and the grinding element body are arranged. The angle with the surface of the spiral arrangement is 3 degrees or more, and the direction of the spiral arrangement of the grinding element and the direction orthogonal thereto
It is characterized in that provided in the grinding elements of each of the expanded portion for regulating the movement in two directions adjacent to the.

Since the grinding elements are arranged in a spiral shape having the above-mentioned angle and the enlarging portion for restricting the movement in the adjacent direction is provided, the intended problem can be solved as will be described later.

The rod-shaped body containing the abrasive grains has a diameter of 3 mm or more, and the rod-shaped body is attached to the roll shaft via a spring material. This is to have

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 (A) is a front view of a fan-shaped board in which grinding element bodies are implanted, FIG. 1 (B) is a plan view showing the arrangement of grinding element bodies, and FIG. 2 is a fan-shaped board with grinding element bodies. 3 is a cross-sectional view showing a mounting structure for the roll shaft of FIG. 3, FIG. 3 is a plan view of an enlarged portion of the grinding element body, and FIG.

Reference numeral 1 is a grinding element body, and the grinding element body 1 is composed of a rod-shaped body 11 containing abrasive grains and a spring material 12 having the bar-shaped body 11 bonded thereto. The coupling between the rod-shaped body 11 and the spring material 12 is performed by the sleeve 13.

The rod-shaped body 11 is in a state in which it is radially arranged on the roll shaft 2 around the circumference of the roll shaft 2 through the spring material 12 (strictly, the fan-shaped board 15 in which the spring material 12 is planted) and gathered in the axial length direction. It is attached below.

The grinding element 1 has a spiral arrangement,
That is, the angle θ between the surface in the lengthwise direction of the roll shaft 2 and the spirally arranged surface is 3 degrees or more.

The grinding element 1 is formed with an enlarged portion 14 for restricting the movement of the grinding element 1 in the adjacent direction.

The aggregate of the grinding element bodies 1 mounted on the shaft 2 is tightened in the same manner as in the prior art from both ends in the direction of the shaft 2,
The brush roll 10 is as shown in FIG.

In the particular arrangement of the grinding element 1 described above,
The locus of the circle drawn by the abrasive grain-containing rod-shaped body 11 of the grinding element 1 when the roll shaft 2 rotates and the rod-shaped body 11 has a thickness of 3 mm or more and is thicker than 3 mm. This is a mode in which the ends of the rod-shaped body 11 that makes a circular motion subsequent to the passage of the parts pass in a superposed manner and the ends of the rod-shaped body 11 in the longitudinal direction of the axis 2 overlap each other.

The enlarged portion 14 provided in the grinding element body 1 restricts the movement of the grinding element body 1 in the adjacent direction, and prevents the grinding element body 1 from breaking the spiral arrangement of a predetermined angle. Therefore,
The overlap of the end loci of the rod-shaped body 11 that makes the preceding circular movement and the rod-shaped body that makes a circular movement behind it is always ensured.

[0016]

Since the present invention has the above-mentioned functions, it solves the problems of polishing and grinding streaks in the conventional heavy polishing brush roll.
