A type of wound brush roller

Abstract

This utility model relates to a wound brush roller, comprising a brush cylinder and brush strips. The brush strips are wound around the outer wall of the brush cylinder. Multiple strip-shaped grooves are arranged in a circular array around the central axis of the brush cylinder on the outer wall of the brush cylinder. Several evenly distributed welding points are provided between the brush strips and the strip-shaped grooves. The beneficial effects are: by providing strip-shaped grooves on the outer wall of the brush cylinder, and by providing several evenly distributed welding points between the brush strips and the strip-shaped grooves when the brush strips are wound around the outer wall of the brush cylinder, it is convenient to weld the brush strips located in the middle of the wound brush roller to the brush cylinder, improving the strength of the weld between the brush strips and the brush cylinder. Furthermore, the welding points are located in the strip-shaped grooves so that the welding points do not affect the subsequent winding of the brush strips onto the brush cylinder; thus, it avoids the brush strips located in the middle of the wound brush roller from loosening, twisting, and deforming during use, and reduces the risk of the welding points at both ends of the brush strips falling off.

Description

Technical Field

[0001] This utility model relates to the field of brush roller technology, and in particular to a wound brush roller. Background Technology

[0002] Wrapped brush rollers are made by winding brush strips around the surface of a brush cylinder and welding the two ends of the brush strips to the surface of the brush cylinder. Because the weld points formed when the brush strips are welded to the brush cylinder in the middle occupy the space on the surface of the brush cylinder, it will affect the uniformity of the subsequent winding of the brush strips. Therefore, existing wrapped brush rollers do not have weld points between the brush strips in the middle and the brush cylinder. As a result, when the wrapped brush roller is in use, the brush strips in the middle of the wrapped brush roller are prone to loosening, twisting and deformation, and even the weld points at both ends of the brush strips may fall off, making the wrapped brush roller unusable. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a wound brush roller.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] A wound brush roller is characterized in that it includes a brush cylinder with a circular cross-section and a spiral brush strip. The brush strip is wound around the outer wall of the brush cylinder. The outer wall of the brush cylinder is provided with a plurality of strip grooves arranged in a circular array with the central axis of the brush cylinder as the center. A plurality of evenly distributed welding points are provided between the brush strip and the strip grooves.

[0006] The width of the strip groove is 6-8 mm.

[0007] The depth of the groove is 2-3 mm.

[0008] Preferably, a counterweight is welded into the strip groove.

[0009] Preferably, a brush shaft with a circular cross-section is installed in the brush cylinder, and the brush shaft is coaxial with the brush cylinder.

[0010] Preferably, a plurality of parallel annular support rings are welded between the brush cylinder and the brush shaft, and the brush shaft, support rings and brush cylinder are coaxial; the support rings are fitted inside the brush cylinder, and the outer side wall of the support rings is welded to the inner side wall of the brush cylinder; the brush shaft is fitted inside the support rings, and the inner side wall of the support rings is welded to the brush shaft.

[0011] The beneficial effects of this utility model are as follows: By setting a strip groove on the outer wall of the brush cylinder, when the brush strip is wound around the outer wall of the brush cylinder, several evenly distributed welding points are set between the brush strip and the strip groove, which facilitates the welding between the brush strip located in the middle of the wound brush roller and the brush cylinder, improves the firmness of the welding between the brush strip and the brush cylinder, and the welding points are located in the strip groove so that the welding points do not affect the subsequent winding of the brush strip on the brush cylinder; thereby avoiding the brush strip located in the middle of the wound brush roller from loosening, twisting and deforming during use, and reducing the risk of the welding points at both ends of the brush strip falling off.
