According to the low-vacuum electrostatic flocking device. Flock falls into flock brushing rollers through grooves in the surface of a feeding roller and enters a flocking chamber after being fully scattered; the flocking chamber is externally connected with a low-pressure mechanism and is in a low-vacuum state; the low-pressure mechanism comprises an extraction opening, a dust collecting box, a filter and a mechanical pump; and a sensor is installed in the dust collecting box, monitors the amount of flock and dust in the dust collecting box in real time and transmits signals to control the opening and closing of the bottom plate of the dust collecting box. With the flocking device adopted, air resistance is reduced, the descending speed of the flock is increased, the flock and an adhesiveare combined more firmly, and a flocking effect is good. 本发明提供了一种低真空静电植绒装置，绒毛经进料辊表面的凹槽落入刷毛滚轮，充分打散后进入植绒室，植绒室外接低压机构，处于低真空状态；低压机构包括抽气口、集尘箱、过滤器和机械泵，集尘箱内安装传感器，传感器实时监测集尘箱内绒毛和灰尘量，并传输信号控制集尘箱底板的开合；本发明实现降低空气阻力，加快绒毛下降速度，使绒毛与胶粘剂结合更牢固，植绒
