Description

Technical Field

[0001] The utility model belongs to the technical field of powder material processing equipment, and in particular relates to powder feeding equipment. Background Art

[0002] Powders are prone to bridging during the feeding process. A vibrating device is commonly used to avoid and break powder bridging. However, since the vibrating method requires repeated knocking of the feeding device, it affects the strength and service life of the feeding device, the noise is also relatively high, and sometimes the more the vibration is performed, the more serious the bridging becomes. There is also a way to prevent bridging in the prior art, that is, the upper motor of the feeding device drives the vertical stirring mechanism, but the stirring paddle of the vertical stirring mechanism only acts on the bridging within the cross-sectional range of the feeding device, and has little effect on the bridging outside the cross-sectional range, and the effect of breaking the powder bridging is not good. Utility Model Content

[0003] The utility model aims to overcome the defects of the powder feeding equipment in the prior art that powder bridging is easily generated during the feeding process and powder cannot be fed smoothly, and provides a powder feeding equipment to overcome the above defects.

[0004] In order to achieve the purpose of the above invention, the utility model is implemented through the following technical solutions:

[0019] Preferably, a plurality of leakage holes are symmetrically arranged on the motor fixing bracket and located on both sides of the rotating shaft.

[0020] The leakage hole is designed to help the powder fall from the leakage hole into the containing cavity, thereby effectively preventing excessive powder from accumulating on the motor fixing bracket.

[0021] Preferably, the bottom end of the dust-proof arch-breaking cover is connected to the motor fixing bracket, and the dust-proof arch-breaking cover includes an arch-breaking portion and a dust-proof portion, and also includes a cavity for accommodating the pneumatic motor.

[0022] By setting up an integrated dust-proof arch-breaking cover, the functions of arch-breaking, dust-proofing and accommodating the air motor are integrated into one, which improves the overall compactness and helps to improve space utilization. It not only ensures the placement of the air motor, but also realizes the arch-breaking and dust-proof functions, which helps to extend the service life of the air motor and improve the safety performance of the equipment.

[0023] Preferably, the broken arch portion is conical.

[0024] The arch-breaking part is conical in design, which is conducive to forming a downward powder flow channel.

[0044] By providing a stirring paddle 9, the powder material falling into the accommodating chamber 2 of the powder hopper connecting assembly 1 after the arch is broken is stirred, effectively preventing the accumulation of the powder material and further avoiding the agglomeration of the powder material. At the same time, the stirring paddle 9 is connected to the outer wall of the rotating shaft 3, and the rotation of the rotating shaft 3 drives the stirring paddle 9 to rotate, thereby achieving uniform mixing of the powder material.
