Description

Technical Field

[0001] The utility model relates to the technical field of industrial brushes, in particular to a grinding brush sheet. Background Art

[0002] Abrasive brushes are widely used in surface treatment and finishing. Their main function is to grind, polish and polish the surface of a workpiece by fixing the brush on the grinding equipment and rotating it. Existing abrasive brushes are usually multiple sets of brushes of the same size and shape installed on a brush roller. Since there are gaps between adjacent bristles on a single brush (such as Figure 2 As shown in the figure, after installing multiple sets of brush pieces, a gap groove will be formed, which will cause the bristles on the entire brush roller to be unevenly distributed. During the grinding process, the bristles cannot evenly contact the surface of the workpiece, resulting in poor grinding effect of the workpiece. Utility Model Content

[0005] Preferably, the brush piece 1 and the brush piece 2 are coaxially arranged.

[0006] Preferably, the inner sides of the fixing plate 1 and the fixing plate 2 are both provided with positioning grooves for mounting the brush plate on the brush roller, and the positioning grooves on the fixing plate 1 and the fixing plate 2 are both on the same axis.

[0007] Preferably, the number of the positioning grooves is not less than three.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Abrasive brushes are tools used for surface treatment and processing, usually with a brush-like or sheet-like structure, mainly made of bristles 112 (which can be nylon, wire, natural hair, etc.) embedded in a substrate (such as plastic, metal or other materials). Abrasive brushes are widely used in surface grinding, cleaning, deburring, polishing and grinding of metal, wood, plastic and other materials.

[0023] Embodiment 1:

[0024] Based on the technical defects of the prior art that the uneven distribution of the bristles 112 leads to poor workpiece grinding effect, please refer to Figure 1-Figure 6 The utility model provides a grinding brush sheet, in which the bristles 112 on the entire brush roller can be evenly distributed, and the bristles 112 can evenly contact the surface of the workpiece, thereby solving the problem of poor grinding effect of the workpiece, including a brush sheet group 1, the brush sheet group 1 is composed of a brush sheet 11 and a brush sheet 2 12, the brush sheet 1 11 includes a fixing sheet 1 111, and the fixing sheet 1 111 is provided with a plurality of equally distributed bristle fixing holes 1111 at a position close to the outer edge, and the brush sheet 2 12 includes a fixing sheet 2 121, and the fixing sheet 2 121 is close to the outer edge. A plurality of equally spaced bristle fixing holes 1211 are provided at the edge of the brush, and a plurality of bristles 112 are inserted into the bristle fixing holes 1111 and the bristle fixing holes 1211, and the positions of the bristle fixing holes 1111 and the bristle fixing holes 1211 are staggered. By staggering the positions of the bristle fixing holes 1111 and the bristle fixing holes 1211 on the brush sheet 11 and the brush sheet 2, the bristles 112 on the brush sheet 11 and the brush sheet 2 will fill the gap between them (such as Figure 6 As shown), the bristles 112 on the entire brush roller are evenly distributed.

[0025] In order to increase the density of the bristles 112, the brush sheet 1 11 and the brush sheet 2 12 are coaxially arranged; thus, the bristles 112 on the brush sheet 1 11 and the brush sheet 2 12 can be closely attached to each other, so that the density is higher.

[0026] To facilitate the installation of the brush set 1, the inner sides of the fixing plate 1 111 and the fixing plate 2 121 are provided with positioning grooves 1113 for installing the brush on the brush roller, and the positioning grooves 1113 on the fixing plate 1 111 and the fixing plate 2 121 are all on the same axis; the positioning grooves 1113 can be used to install the brush plate 1 11 and the brush plate 2 12 on the brush roller.

[0027] In order to improve the stability of the brush set 1 after installation, the number of the positioning grooves 1113 is not less than three.

[0028] In order to fix the bristles 112, a wire fixing hole 1112 and a wire fixing hole 1212 are respectively provided at positions close to the outer edges of the fixing plate 111 and the fixing plate 2 121, and adjacent wire fixing holes 1112 and 1212 are each provided with a binding wire 113 for binding the bristles 112; the binding wire 113 is passed through the adjacent wire fixing holes 1112 and 1212, so that the bristles 112 can be bound to the fixing plate 111 and the fixing plate 2 121, thereby fixing the bristles 112.

[0029] In order to adapt to the staggered distribution of the bristles 112, the positions of the wire-binding fixing hole 1112 and the wire-binding fixing hole 2 1212 are staggered, so that the bristles 112 of the fixing plate 1 111 and the fixing plate 2 121 can be conveniently bound and fixed.

[0030] It can be known from the above embodiments that: the bristles 112 are tied to the fixing plate 111 and the fixing plate 121 by using the binding wire 113, and then the brush plate 11 and the brush plate 2 12 are installed on the brush roller through the positioning groove 1113. Since the positions of the bristle fixing holes 1111 and the bristle fixing holes 1211 on the brush plate 11 and the brush plate 2 12 are staggered, the bristles 112 on the brush plate 11 and the brush plate 2 12 will fill the gap between the two, thereby making the bristles 112 on the entire brush roller evenly distributed.

[0031] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
