Abstract

A mixed powder quantitative conveying and paving device comprises a silo, a powder conveying device, a powder paving device, a powder scattering device and an anti-blocking device. The powder scattering device is two large pin shafts fixed to the middle of the silo and rotating in the opposite directions, and scattering and carding are conducted on mixed powder through the powder scattering device. The anti-blocking device is a small rotatable pin shaft fixed to the upper portion of a silo outlet, and the mixed powder is prevented from being blocked through rotation, the powder conveying device comprises a symmetrically arranged and synchronously operated belt pulley pair, the two belt pulley pair is fixed in belt pulley pair bearing holes through sliding groove rails, bearing sliding blocks are fixedly arranged between spindles of the belt pulley pairs, the bearing sliding blocks can slide in the sliding groove rails, and the belt pulley pair can slide along with sliding of the bearing sliding block to adjust the size of a gap of the outlet. The mixed powder quantitative conveying and paving device is suitable for quantitative and even paving conveying of various mixed powders of different particle sizes.

Description

technical field [0001] The invention relates to a mixed powder quantitative conveying and paving device, which can evenly spread mixed powders with different particle sizes on a working platform, and belongs to the field of mechanical equipment manufacturing. Background technique [0002] In the process of powder forming, how to evenly spread the mixed powder with different particle sizes is a technical problem. As an important part of the process, the powder spreading device has a significant impact on the quality of the entire system. [0003] At present, in the field of powder forming technology, there are four commonly used powder feeding and spreading methods: scraper type, roller type, moving hopper type and vibration type. Patent 1 (Application No. 03213749.4) discloses a mobile hopper-type powder spreading device. The powder spreading process is as follows: the movable raw material box is loaded with an appropriate amount of powder, the piston of the workpiece box is...
