Description

[Detailed description of the invention] The present invention forms a wavy curve consisting of a concave curve and a convex curve in the annular region including the outer edge of the foil plate attached to both sides of the circular brush body. The present invention relates to a rotating brush characterized in that a brush rubbing surface is formed in a shape that matches the waveform of the foil plate.

A conventional rotating brush A of this type is, for example,
- As shown in Publication No. 472, a foil plate is attached to both sides of a brush mounting plate which is made by folding a plurality of brush materials in half and attaching them radially with the bristles facing in the diametrical direction, and from the foil plate inward. There is a structure in which a plurality of cut and raised wedge-shaped locking claws are pushed into the brush, and their tips are bent in opposite directions to hold and secure the mounting base of the brush material. Because all of the bristles stand upright in the diametrical direction, the bristles are uniformly bent in the counter-rotational direction due to the frictional resistance caused by high-speed rotation, reducing the polishing effect, and the tip surface of the brush material is arranged in a perfect circle. Therefore, when a roll brush is formed by arranging multiple rotating brushes in parallel, the boundaries between adjacent rotating brushes are circular, so if used under rotational centrifugal force, brush marks may appear on the surface of the polished product. It was not possible to obtain a good polishing or cleaning finish.

Therefore, the present invention was devised with the intention of solving the above-mentioned drawbacks, and the structure thereof will be explained below with reference to FIGS. 1 to 7 showing one embodiment. A circular brush body 3 is formed by attaching the bristles of the brush material 1 to a brush material mounting plate 2 radially in the diametrical direction, and one or more circular brush bodies 3 are stacked one on top of the other, and foil plates 4 are attached on both sides thereof. The rotary brush A has an annular region 13 including the inner edge of the shaft hole 12 of the foil plate 4 as a flat surface, and an outer edge 5 of the foil plate 4 continuous with the flat surface. Concave curved portions 7 and convex curved portions 8 are alternately formed in the annular region 6 containing the circular brush body 3 by pressing, for example, to form a waveform, and while pressing the side surface of the brush material base of the circular brush body 3 with the concave curved portion 7. , the concave portions 9 and convex portions 10 which are released by the convex curved portion 8 and synchronized with the waveform of the foil plate 4 are interconnected to form the tip of the hair (rubbing surface) into a waveform. The concave curved portion 7 and the convex curved portion 8 extend above the outer edge of the brush material mounting plate 2, and directly reach the waist portion of the brush material that is not restrained by the brush material mounting plate 2. to create a more pronounced wave shape.

As shown in FIG. 3, preferably, the concave curved portion 7 of one foil plate 4 and the convex curved portion 8 of the other foil plate 4 are directly opposed to each other, so that pressure is applied from one side and released to the other. Yotsute brush material 1
A beautiful wave-shaped bend can be formed without putting stress on the body. In this case, the brush material mounting plate 2 may also be bent into a waveform in accordance with the above.

As is known in the art, the foil plate 4 has a locking pawl 4a cut and raised inward to hold the mounting base of the brush material 1 attached to the brush material mounting plate 2. A plurality of locking claws 4a are arranged at intervals in the annular region 6 having the concave curved portion 7 and the convex curved portion 8, and the tip portions of the locking claws 4a are bent in opposite directions as shown in FIG. As a result, the foil plate 4 is fixed to both sides of the circular brush body 3 while holding the mounting base of the brush material 1 to the brush material mounting plate 2.

Further, as shown in FIG. 5, the foil plate 4 is
The bearing part 11 of the rotating shaft 12 is formed only on one side, or the bearing part 11 is formed on both sides as shown in FIG.
form.

Therefore, as described above, the present invention forms a corrugated shape by connecting a concave curve and a convex curve in the annular region of the foil plate, and presses the side surface of the base of the brush material inward at each concave curve. Since the convex curved part is configured so that the brush material escapes outward, the brush material is raised in the diametrical direction, and is also forced to tilt sideways so that the bristles have a wavy peripheral surface in the upright state. As a result, the brush material has a strong stiffness and strong restoring properties during rotational rubbing, making it difficult for the bristles of the brush material to bend in the counter-rotational direction during polishing, which may cause curling as in conventional brushes. It has the advantage that a polishing effect can be expected over a long period of time without any problems.Furthermore, since the bristles (rubbing surface) of the rotating brush exhibit a waveform as shown in Figure 2, multiple brushes can be used as shown in Figure 7. It has the advantage of not causing uneven polishing when used in parallel, and reliably preventing brush marks from conventional brush marks.In addition, it has the advantage of preventing the bending of the bristles and the occurrence of brush marks as mentioned above. The brush can be used for a long period of time until it wears out to a large extent, and the running cost of the rotating brush can be reduced, and various other practical effects can be achieved. Furthermore, in the present invention, the concave curved portion and the convex curved portion formed in the outer peripheral annular region of both foil plates extend to the outside of the outer edge of the brush material mounting plate, and the concave curved portion and the convex curved portion are formed on the outer peripheral annular region of the brush material mounting plate. Since the brush material is applied to the unrestricted waist portion of the brush material to form the above-mentioned wavy flocked state, the brush material mounting plate does not need to be corrugated.
The two foil plates mentioned above directly apply pressure and relief to the brush material, making it possible to form a remarkable wave shape. In addition, a plurality of locking claws are cut and raised in the annular region where the concave curved part and the convex curved part are formed, and the tips of the claws are engaged with the brush material mounting base to fix the foil plate. It is possible to make the engagement more solid by inserting the locking claws present deeper inward and bending them more deeply, thereby making it possible to make the connection between both foil plates and the circular brush material more robust.
