Description

  The present invention relates to a brush using resin bristles.

  As a brush using resin brush bristles, the brush bristles are placed across the long channel of the metal strip, and the core wire meandering into the corrugated shape is applied to it, and the core wire is pushed into the long channel. Folding the bristle in half and pinching the left and right edges of the long channel to pinch the bristle into a corrugated shape, and the bent part of the bristle is implanted in the long channel It has been known. (See Patent Document 1)

In addition, in brushes used for cleaning or polishing, there are known implant brushes in which fiber bundles obtained by bundling ultrafine fibers are planted in the brush body. (See Patent Document 2)

  In the case of the channel brush, since the metal is used, both the brush and the shaft are heavy. In addition, in the case of an implant brush, since it is implanted in synthetic resin or wood, there is no weight unlike a channel brush. However, as for the amount of brush hair, the channel brush is more than twice as large as the implanted brush. Further, there is a case where the brush bristles come out of both the channel brush and the implanted brush. Thus, the brush reduced in weight using the resin brush bristles does not have a sufficient amount of bristles, and the brush bristles are desired to be improved.

  The present invention solves the above-described problems, and provides a welding brush that is reduced in weight by using resin brush bristles, in which the brush bristles are not easily removed and the amount of bristles is sufficiently large. Objective.

  According to a second aspect of the present invention, the resin base is long, and the resin bristles are formed in a state of protruding from one surface of the resin base and continuing in the longitudinal direction. 1. A welding brush according to 1.

  According to a third aspect of the present invention, the long resin base has a rod-shaped shaft coaxially in the longitudinal direction, and the resin brush bristles project radially outward from the resin base. It is the welding brush of Claim 2 currently fixed.

  The invention according to claim 4 is the welding brush according to claim 2 or 3, wherein the long resin base is wound around a long member and fixed by welding.

  According to a fifth aspect of the present invention, the resin base has a thick annular or disk shape, and the resin brush bristles protrude from the peripheral surface of the resin base and are welded to the resin base. The welding brush according to claim 1, wherein the welding brush is molded in a finished state.

  According to a sixth aspect of the present invention, the brush bristles of the resin protrude from one surface of the base of the resin, and a shaft protrudes from the surface different from the one surface. It is a welding brush as described in above.

  According to a seventh aspect of the present invention, the resin base on which the shaft is molded has a thick disk shape, and the long resin base is fixed by welding along the edge of the disk. 4. The welding brush according to claim 3, wherein said resin brush bristles are provided in a ring shape on the back surface of one surface on which said shaft of said resin base is formed.

  The invention according to claim 8 is the welding brush according to claim 3, wherein the resin base on which the shaft is molded is a cylindrical shape, a prismatic shape, or a cup shape.

  The present invention is a brush that is reduced in weight by using resin brush hairs, and the brush hairs are not easily removed, and the amount of brush hairs can be increased sufficiently.
