Abstract

PURPOSE:To sufficiently wash the deposits on the surface of articles having rugged surfaces by fixing abrasive grains via binder layers on the surface of twisted wires or stranded wires of flexible wires and fixing many brush wires to a rotating body. CONSTITUTION:The cylindrical brush A fixed with the many brush wires 1 formed by doubling and twisting the flexible wires consisting of cotton yarn, synthetic fiber yarn, soft nylon, etc., is formed by incorporating the abrasive grains 2 of molten alumina, silicon carbide, artificial diamond, etc., into the binder layers 3 consisting of liquefied rubber or resin or adhesives, passing and sticking the brush wires therein, and solidifying the binder layers 3. The binder layers 3 intrude into recessed parts 4 formed in the twisting spaces of the twisted wires and, therefore, the abrasive grains 2 are strongly fixed at a high density to the brush wires 1. The thickness of the binder layers 3 is set at about 1/2 to 2/3 the diameter of the abrasive grains 2 and the abrasive grains 2 are held partly exposed to the outside. The brush wires 1 having flexibility are deflected by their resilience and move by following up the rugged surface B. The front ends of these wires intrude well into the recessed parts as well. The deposits C are thus smoothly scraped off.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a brush for cleaning the surface of an article or removing rust.

(Prior Art) Conventional brushes used for removing deposits from the surface of articles are generally made of metal wire, strong rigid resin wire, etc. In order to improve the cleaning ability, a brush has been proposed in which abrasive grains are fixed to the surface of the brush wire via a binder layer by, for example, electrodeposition. However, since this brush wire is made of a single wire, its surface is smooth and the binder layer cannot dig into it, so the bonding force of the abrasive grains to the brush wire is insufficient, and if the deposits are strong, the abrasive grains may be stuck to the binder layer. At the same time, it has the disadvantage that it easily falls off from the brush wire. Furthermore, since the brush wire is a single wire, if the brush wire is made of a material with high rigidity so as to be able to resist strong deposits, there is a problem in that it tends to be bent or bent.

To solve this problem, as shown in Japanese Utility Model Application Publication No. 2-82924, by using stranded wires for the brush wire material, a binder layer is inserted into the recesses formed in the twisting spaces on the surface of the stranded wires, and the abrasive grains are removed. A brush has been proposed that increases the bonding force to the brush wire and also prevents bends and creases in the brush wire.

(Problem to be Solved by the Invention) However, since the above-mentioned conventional brush wire is made of metal or strong synthetic resin, it is hard and, for example, when cleaning the surface of an article with an uneven surface, it may cause deposits to form along the uneven surface. There was a problem in that it was difficult to stir up the water sufficiently.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has the following features:
The present invention is characterized in that a large number of brush wire rods each having abrasive grains fixed thereto via a binder layer are fixed to a rotating body.

(Function) Brush wire rods made of stranded wires or braided wires made of flexible wires with abrasive grains fixed to them bend due to their flexibility, follow the uneven surface of the article, and the tip easily enters the recesses, thereby preventing deposits. can be sufficiently stirred up.

In addition, due to the centrifugal force generated by the rotation of the rotating body, the brush wire to which the abrasive grains are fixed comes into contact with the surface to be cleaned, strongly scraping up the deposits, so that even hard deposits can be removed.

Furthermore, since stranded wire or braided wire is used for the brush wire, the binder layer bites into the recesses formed on the surface of the stranded wire or braided wire and is fixed, so compared to the case where a brush wire made of a single wire is used, The bonding force of the abrasive grains to the brush wire can be improved.

(Embodiment) Figures 1 to 4 show an embodiment of the present invention, in which a cylindrical brush A is shown in which a brush wire 1 made by twisting together a large number of flexible wire materials such as cotton threads, synthetic fiber threads, and soft nylon is fixed. It shows.

The brush wire 1 includes abrasive grains 2 such as molten alumina, silicon carbide, and artificial diamond, and a binder layer 3 such as rubber or resin such as urethane rubber, fluororubber, or nylon.
It is attached to the surface through. The abrasive grains 2 are attached to a binder layer 3 made of the liquefied rubber, resin, or adhesive.
The brush wire 1 is passed through the brush wire 1 and adhered thereto, and then the binder layer 3 is solidified to be fixed. However, since the brush wire 1 is a stranded wire, the binder layer 3 is mixed into the space between the strands of the stranded wire. Because it enters the recess 4 that is formed,
The abrasive grains 2 are fixed to the brush wire 1 more strongly and densely than when a single wire is used. At this time, the thickness of the binder layer 3 is about 1/2 to 2/3 of the diameter of the abrasive grains 2, and as shown in FIG. be.

If the cylindrical brush A with the above configuration is used to remove the deposits C stuck to the surface of the uneven surface B, the fourth
As shown in the figure, the flexible brush wire 1 bends due to its flexibility, moves to follow the uneven surface B, and its tip fits well into the recesses to sufficiently scrape up deposits C. In addition to the high hardness of the abrasive grains 2, which has excellent abrasive power, the centrifugal force generated by the rotation of the cylindrical brush A causes the brush wire 1 to come into contact with the surface to be cleaned vigorously, and the hard deposits C are also strongly removed. stir up Since the deposit C scraped up in this way is smoothly scraped off by the brush wire 1,
Effective cleaning can be performed. Furthermore, since the brush wire 1 is a stranded wire, the binder layer 3 enters the recess 4 and is firmly bonded to the brush wire 1, so that the abrasive grains 2 do not easily fall off.

The present invention can be constructed in various ways other than those shown in the above embodiments, and the brush wire may be a braided wire made of flexible wires woven into three, four or eight braids, or a cylindrical wire. It can be formed into various brush shapes other than a brush.

For example, as shown in FIG.
In the case of a brush to which a brush is fixed, cleaning can be performed by rotating it around the rotating shaft 6 or moving it in various directions such as front, rear, left, and right, so that it can also be used for articles with complex uneven surfaces.

(Effects of the Invention) Since the present invention has the above-described configuration and operation, it can strongly scrape up deposits on the surface of an article with an uneven surface to the concave portions, and
Can be thoroughly washed. Also, since the abrasive grains do not easily fall off, the cleaning power can be maintained for a long period of time.
