Description

Anti-winding rolling brush Technical Field The utility model belongs to the technical field of ground cleaning equipment, and particularly relates to an anti-tangling rolling brush. Background The cleaning equipment such as the sweeper is provided with the rolling brush, the ground is cleaned by rotating the rolling brush, long dirt and foreign matters such as hair are rolled into the rolling brush in the cleaning process, are wound on the rolling brush, are more accumulated and more difficult to treat, and reduce the cleaning efficiency, so that the normal operation of the sweeper is affected; 202510004247.9, a rolling brush mechanism and a cleaning device are provided, wherein the rolling brush comprises a brush shaft with a cavity, a brushing assembly, a transmission assembly and a cutting assembly, the brushing assembly is arranged on the peripheral wall of the brush shaft, the brushing assembly can guide cleaned garbage from two ends of the brush shaft to the middle area of the brush shaft, at least part of the transmission assembly is positioned in the cavity, the cutting assembly is arranged in the middle area of the brush shaft, the cutting assembly comprises a cutter tooth part and a cutter seat part, the cutter seat part is fixedly connected with the brush shaft, and the technical scheme is that the structure of the rolling brush can solve or relieve the problem of reduced rolling brush cleaning efficiency caused by winding hair foreign matters around the rolling brush; The device requires the separate production of the blade holder, which, although high in strength, has the following disadvantages: The cutter seat piece is connected with the second shaft shell in an embedded mode, the cutter seat piece is processed and the sinking groove is formed although the installation is compact, corresponding working procedures are needed for the connection of the cutter seat piece and the second shaft shell, and obviously, the cost is increased; 2. Secondly, most of traditional blade holders and cutter teeth adopt metal structures, and though the metal structures have reliable strength, the metal structures are not favorable for light weight, and have poor corrosion resistance and noise reduction performance because working procedures such as cutting and polishing are needed during processing.
