The invention discloses a dust blowing mechanism of a sander, which comprises a guide pipe, a swinging cylinder, a dust blowing pipe, a swinging connecting rod mechanism and a blower mechanism. The dust blowing pipe is characterized in that the dust blowing pipe is a hollow structure (pipe body), a plurality of air outlets are arranged at the bottom, one end of the dust blowing pipe is closed, and the other end is connected with a guide pipe through a pagoda joint. The air guide pipe is connected with the dust blowing pipe and the blower mechanism. The swinging cylinder is connected with the dust blowing pipe through the swinging connecting rod mechanism, and drives the dust blowing pipe to swing to form an airtight gas barrier. The invention produces an airtight continuous and stable air flow barrier to concentrate dust on the bottom of the sanding roller, and inhales the dust collection bag through the dust suction port for centralized and unified treatment, thus effectively preventing dust from splashing out and polluting the environment. The invention solves the problems that a large amount of dust is produced during the grinding process of the workpiece by the sander, and the dust is easy to splash and difficult to be centralized handled. In addition, the invention is detachable and easy to maintain.

一种砂光机吹尘机构
本专利技术涉及一种吹尘机构,具体涉及一种砂光机用吹尘机构。
技术介绍
砂光机是现代木材加工工业广泛应用的主要设备之一。用于各种人造板材、木制品构件和木制品零件的精加工,以提高其表面光洁度等,为木制品零件的油漆或板材的二次加工,如木纹印刷、贴纸和贴薄木等获得良好的基准面。砂光机砂削工作时,会产生大量粉尘导致生产车间粉尘浓度严重超标,污染车间环境,危害人们身体健康;此外,大量粉尘会加速机械零件磨损,还会糊死砂带,使砂带堵塞,影响砂削效率和降低产品质量。然而,从砂削粉尘特点来看,其颗粒直径小、质轻量大、形态复杂、表面粗糙极易悬浮飞扬,极大增加了砂光机除尘难度。现有的砂光机除尘技术包括湿式除尘、超声波除尘、静电除尘、袋式除尘等。湿式除尘包括喷淋式、水膜式、水浴式等虽有良好的除尘效果,但需定期处理尘浆和污水,受地区、季节和温度的限制较大,超声波和静电除尘投资过大。袋式除尘是将粉尘通过吸尘通道排入集尘袋,最后将粉尘统一处理,尽管此种方式可以将大部分粉尘清除,由于砂削粉尘具有极易分散的特点,在砂光机工作时仍有大量粉尘逸出,污染环境。因此砂光机除尘仍然是一项亟 ...
