Abstract

PURPOSE:To make a brush roll attachable firmly and stably, by disposing plural rubber-like elastic tubes on a brush roll shaft, while compressing and binding a brush disc parallel body jointly installing a surface treatment fiber on its circumferential surface by means of pressure fluid inflow. CONSTITUTION:Each brush disc 1 planting surface treatment fibers 2 is laminatedly installed on a shaft 3, then each of flanges 4 and 4 is applied to both sides, and a snap spring 6 is inserted into a groove 5 in the axial direction, while each axial turning direction is bound with a key 7. In addition, plural rubberlike elastic tubes 13 are disposed on the shaft 3 at regular intervals with a key way bottom part or the like, extending in the axial direction, and a nozzle part 15 of a pressure fluid injection block 14 is connected to one end while an air vent block 16 is connected to the other end. And, in time of being necessary, pressure fluid is poured into each tube 13 via a needle valve 18, expanding the tube, and when the valve 18 is closed, a parallel body of these brush discs 1 is strongly compressed to the shaft 3 and bound thereat. Thus, minute vibrations during rotation are prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a brush roll, in particular, a brush disk made of a thin metal plate having surface-treated fibers such as tampico Pli fibers, nylon threads, and abrasive threads attached to the outer peripheral surface, which are laminated on top of a shirt. Concerning compressed and mounted brush rolls.

Such a brush roll is conventionally known, and since the roll itself is made up of a parallel body of brush disks in which a large number of fR layers are pressed, it can be easily manufactured even in the case of a long roll. However, on the other hand, due to the need for space when pressing and compressing the brush disk fitted to the shaft, and the handling when replacing an 81n brush disk with a new one, the shaft and brush disk are There must be a relatively large gap between them, with a difference in diameter of about 0.3 to 1.0 III, and the high speed rotation of the brush roll (90
During brushing at a temperature of 0 to 120 Or, Il, lIl), the brush disk parallel body vibrates slightly against the shirt I, and if the brushing is for surface treatment such as polishing or cleaning a metal strip, the treated surface may be exposed to dust. occurs.

Therefore, the present invention aims to overcome the problems caused by the special circumstances of the front claw of the brush roll of the above-mentioned type, and to ensure that the parallel body of brush disks is mounted on the shaft under stable conditions without slight vibrations. It is.

The brush roll of the present invention is a brush that is mounted on a shaft by laminating and compressing a large number of brush disks made of thin metal plates with surface-treated fibers such as tampico Ili fibers, nylon threads, and abrasive threads attached to the outer peripheral surface. The roll includes, on the shaft, a plurality of rubber-like elastic tubes extending in the axial direction of the shaft, which are expanded by pressurization of a pressurized fluid to compress and restrain the parallel body of brush disks, at equal angles. It is characterized by being arranged in a distributed manner, and can be used for brushing for various surface treatments, such as polishing, cleaning, removing scratches, adjusting surface roughness, removing scale, and removing molding sand.

According to the present invention, a rubber-like elastic dupe extending in the axial direction of the shaft is arranged on the shirt 1 to which a large number of brush disks are laminated and compressed, and a pressurized fluid is injected into the dupe to inflate the shirt. , thereby compressing and restraining the parallel bodies of brush disks from the shirt 1 to the top, so that the parallel bodies of brush disks can be attached to the shaft in a stable and firm state in the direction of rotation of the brush roll without causing slight vibrations. is guaranteed.

Furthermore, since a plurality of these rubber-like elastic tubes are arranged at equal angles, the brush disk parallel body can be compressed evenly in the radial direction by expansion due to pressurized fluid, and the brush disk parallel body can be compressed evenly in the radial direction. There is no possibility of shifting due to expansion of the rubber-like elastic duplex.

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

Arrange multiple pieces at even angles around the . The rubber-like elastic body dupe (13) may be disposed at the bottom of the keyway as shown in the figure, or at any other location. One end of the rubber-like elastic body dupe (13) is connected to the cylindrical tip (15) of the pressurized fluid injection block (14), and the other end is connected to the air vent block (15) when liquid is used as the pressurized fluid.
Connect G). The pressurized fluid injection block (14) has an injection port (17) that communicates with a source of pressurized fluid, and a needle valve (18) that closes the injection port (17). Air vent block (
