Powder feeder

Abstract

The utility model discloses a powder feeder, which comprises a storing tank, a powder flow-quantity adjusting valve and a linear vibrator, wherein the powder flow-quantity adjusting valve is arranged on the storing tank, the linear vibrator is arranged below the storing tank and is used for vibrating the storing tank, and the linear vibrator is obliquely arranged in an intersecting structure at an acute angle of the axial direction of the linear vibrator and the horizontal advancing direction of powder in the storing tank. The flow quantity of the powder can be adjusted through the powder flow-quantity adjusting valve, so that the precision and the stability of the blanking quantity are ensured, and the blockage caused by the overlarge flow quantity is avoided; the storing tank can be vibrated through the linear vibrator, so that the powder makes parabolic movement and advances in a wavy type, the conglobation of the powder by bonding is eliminated, and therefore the density of the powder is uniform and compact, the frictional force of the powder is reduced, the steady operation, the stable flow-quantity and the smooth movement of the powder can be ensured, and the blockage of the storing tank is avoided; and the discharging end of the storing tank is V-shaped closed, and a discharging opening is arranged at a V-shaped corner part, so that the excessive powder can be prevented from being accumulated at the discharging end of the storing tank through the design of a special structure, and the blockage of the discharging opening is avoided.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a feeding device. Background technique [0002] The main purpose of the powder feeder is to realize the precise feeding function of powder under the condition of ensuring the safety of equipment and personnel. [0003] There are two methods of manual feeding and automatic feeding in the prior art. Manual feeding has defects such as low degree of automation, large time consumption, rough operation, and low accuracy of powder amount; while the current automatic feeding equipment uses The powder feeding method is easy to block the feeding pipe, the inclined powder conveying method used by the automatic feeding equipment has poor fluidity, and the automatic feeding equipment relies on gravity to feed the powder, which is prone to a large amount of residual powder accumulation. [0004] Therefore, the current powder feeding equipment has many defects, which are not conducive to the smooth reali...
