Vacuum powder feeding machine for regenerated rubber production

The utility model discloses a vacuum powder feeding machine for regenerated rubber production, and belongs to the technical field of solid waste disposal and comprehensive utilization. In order to solve the problems that due to the fact that too much rubber powder is fed, blockage, bridging and the like are prone to occurring, the powder feeding speed is reduced, and blockage is prone to occurring in the feeding process when a feeding pipe is not cleaned for a long time, a vacuum pump is fixed to the top of the tank, and a fixing plate is fixed to the top of an inner cavity of the tank; the bottom of the vacuum pump is fixedly communicated with an air guide pipe; the bottom of the air guide pipe penetrates through the tank body and extends to the aperture position of the surface of the fixed plate; compared with the prior art, the rubber powder stirring tank has a certain stirring effect on rubber powder entering the tank body and has a certain stirring range, so that the powder entering the tank body can be
