Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is mainly used for cylindrical brushes for cleaning the surface of metal plates and removing rust. In particular, the cylindrical brush of the present invention is highly effective when used to remove carbonized deposits from the surface of an iron plate for grilling.

(Prior art and its problems) A conventional cylindrical brush is generally constructed by attaching a metal brush wire b to a cylindrical base a, as shown in an example in FIG. When used for cleaning work to remove deposits, there was a problem in that the cleaning effect would be lost within a short period of time due to curling.

Another problem was that if the cylindrical brush was strongly applied to the surface of a metal plate, the metal brush wire b would break at the base.

(Purpose of the invention) The object of the invention is to provide a cylindrical brush that prevents the above-mentioned bending and breakage and maintains good cleaning effects over a long period of time.

(Structure of the invention) In order to achieve the above object, the present invention provides a cylindrical brush in which a metal brush wire 2 is attached to a cylindrical base 1 as shown in the principle diagram in FIG. 3, 3 was buried in close proximity to a restraining member 4 made of rubber or soft synthetic resin that has rubber elasticity and elastically restrains the movement of the metal brush wire 1 in the circumferential direction. It is characterized by

(Embodiment) In the embodiment shown in FIGS. 2 and 3, on the outer circumferential surface 5 of a cylindrical base 1 such as a drum, pipe, or shaft,
A predetermined number of brush units 7 each supporting a metal brush wire 2 are attached to a metal support channel 6 at a predetermined interval by welding in the axial direction of the cylindrical base 1, while filling the gaps between each brush unit 7. A restraining member 4 made of soft rubber formed into a strip having a predetermined cross-sectional shape is attached to the outer circumferential surface 5 using bolts 8 and washers 9. 10 is a screw hole into which the bolt 8 provided in the cylindrical base body 1 is screwed.

As the metal brush wire 2, stainless steel wire, aluminum wire, steel wire, etc. can be adopted. Further, the heights of the metal brush wire 2 and the restraining member 4 are set to be the same so that the entire rotational direction side parts 3, 3 of the metal brush wire 2 are restrained and supported by the restraining member 4. tip 1
4 is configured to be flush with the outer circumferential surface 15 of the restraint member 4.

The embodiment shown in FIG. 4 has a brush unit support groove 12 and a restraining member support groove 13 on the surface of the cylindrical base 1.
The brush unit 7 and the restraining member 4 are attached to the cylindrical base body 1 using these. A metal channel 11 is attached to the base end of the rubber restraint member 4 to be inserted into the restraint member support groove 13.

When cleaning work such as removing deposits from the metal surface is performed using the cylindrical brush configured as described above, the tip 14 of the metal brush wire 2 wears out while being subjected to the cleaning work, while the restraining member 4 is attached to the metal surface. Due to the frictional heat of
The tip 14 of the metal brush wire 2 is always located on the outer periphery of the cylindrical brush in a state where it can effectively perform cleaning operations. Therefore, the cylindrical brush can be used in a state where it always has an effective cleaning action until the metal brush wire 2 and the restraining member 4 are worn out.

The present invention can be configured in various ways other than those shown in the above-mentioned embodiments, and the means for attaching the metal brush wire 2 and the restraining member 4 to the cylindrical base 1 are not limited to those described above. Alternatively, the metal brush wire 2 and the restraining member 4 may be wound and attached to the cylindrical base 1 in a spiral direction. Further, it is also possible to integrate the metal brush wire 2 in a planted state during the rubber molding of the restraining member 4. Further, in the above embodiment, the tip 14 of the metal brush wire 2 and the outer circumferential surface 15 of the restraint member 4 are flush with each other, but the height of the restraint member 4 is set slightly lower than the height of the metal brush wire 2. The outer peripheral surface 15 of the metal brush wire 2
It can also be configured to be at a lower position than the tip 14 of. In addition to rubber, the restraining member 4 may be made of a soft synthetic resin having rubber elasticity.

(Effects of the invention) Since the present invention has the above configuration, even if the cylindrical brush is rotated in one direction, the brush wire can be rotated with the help of the restoring elastic force of the restraining member from both sides in the circumferential direction. It has the effect of being easy to restore to its original position and less prone to bending. Also, when a strong external force is applied to the brush wire to bend it in a predetermined direction during cleaning, the brush wire can perform the cleaning work with a strong counterforce, and the restraining member having elastic force can bend the brush wire in the circumferential direction. Since the brush wire is properly bent while being closely supported from both sides (see the imaginary line in FIG. 2), the brush wire does not break from the base, which is the case in the conventional example. Furthermore, the outer peripheral surface of the rubber-elastic restraining member made of rubber or soft synthetic resin wears out in the same way as the tip of the metal brush wire, so the restraining member may end up covering the metal brush wire. This eliminates any inconvenience and allows cleaning work to proceed efficiently and smoothly.

As described above, according to the present invention, it is possible to provide a cylindrical brush that maintains good cleaning effects over a long period of time.
