Embodiment 1

[0021] see Figure 1-5 As shown, a centering device for a roller brush includes a central column 1, four horizontal partitions 1 are arranged on the upper part of the outer wall of the central column 1, and two horizontal partitions 2 are provided on the lower part of the outer wall of the central column 1. Four vertical partitions 4 are arranged on the outer wall of column 1, and the included angle between adjacent vertical partitions 4 is 90°, the distance between adjacent horizontal partitions 1 and 2 is the same, and the adjacent horizontal partitions 1 The distance between the 2 is the same as the distance between the horizontal partitions 2 and 3. The center column 1 is provided with a placement groove 5, and the placement groove 5 cuts off one of the vertical partitions, and the placement groove 5 is provided with a centering column 6. The opening of the placement groove 5 is provided with a baffle plate 7, and more than two baffle plates 7 are provided. The baffle plat...

Embodiment 2

[0025] This embodiment has the same structure as the centering device described in Embodiment 1, and the method of use is the same, except that the ratio of the centering column raw materials is different.

[0026] The centering column is composed of the following raw materials in parts by weight: 57 parts of polylactic acid, 29 parts of polyhydroxybutyrate, 12 parts of epoxy resin, 7 parts of silicon dioxide, 6 parts of titanium dioxide, and 27 parts of PET polyester chips.

Embodiment 3

[0028] This embodiment has the same structure as the centering device described in Embodiment 1, and the method of use is the same, except that the ratio of the centering column raw materials is different.

[0029] The centering column is composed of the following raw materials in parts by weight: 65 parts of polylactic acid, 35 parts of polyhydroxybutyrate, 15 parts of epoxy resin, 8 parts of silicon dioxide, 7 parts of titanium dioxide, and 30 parts of PET polyester chips.

Abstract

The invention discloses a centering device of a roller brush. The centering device includes a central column. The upper part of the out wall of the central column is provided with four horizontal partition plates I. The low part of that outer wall of the central column is provided with two horizontal partition plates II. The included angle between each two adjacent vertical partition plates is 90degrees. The distance between each two adjacent horizontal partition plates I is uniform. The central column is provided with a placing groove which cuts off one of the vertical partition plates. A centering column is arranged in the placing groove. A baffle plate is arranged at the opening of the placing groove. The central column and the centering column are concentric. Perforations are arrangedin the central column and the centering column along the central axis direction. The inner walls of the perforations of the central column are provided with female threads. According the invention, by utilizing the centering device, relative shake between bristles and a roller support is avoided.

Description

technical field [0001] The invention relates to a roller brush device, in particular to a centering device for a roller brush. Background technique [0002] Roller brushes are divided into three types: long hair, medium hair, and short hair. It is expressed as the length of the bristles of the roller, not the thickness and length of the roller itself. The bristles are usually divided into two types: wool and chemical fiber. Different roller brushes will produce different effects, and the long-haired roller will produce some fine textures, which have a concave and convex feeling, similar to the texture effect. After brushing with a short-haired roller, the paint surface is relatively uniform, smooth, without unevenness, and the middle hair is in between. Roller brushes are mostly made of wool and foam plastics, and can be divided into paint roller brushes, napping roller brushes, floor paint roller brushes, flat paint roller brushes, etc., and are mainly used for large-area ...
