Embodiment Construction

[0026] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0027] Such as figure 1 and figure 2 As shown, the powder spreading device of the present invention includes a powder spreading box 1 and a powder pushing mechanism 2 . The powder spreading box 1 has a powder storage chamber 11 and a first powder outlet 12, the powder storage chamber 12 is provided with a partition 13, and the partition 13 divides the powder storage chamber 11 into a first powder storage tank 111 and a second powder storage tank 112 , the partition 13 can switch the communication between the first powder storage tank 111 and the second powder storage tank 112 and the first powder outlet 12 . The powder pusher mechanism 2 includes a power input mechanism 21 and a first powder pusher 22 and a second powder pusher 23 respectively movably arranged in the first powder storage tank 111 and the second powder storage tank 112 ....

Abstract

The invention relates to a powder spreading device, comprising a powder spreading box with a powder storage chamber and a powder pushing mechanism, the powder storage chamber is provided with a partition that divides the powder storage chamber into a first powder storage tank and a second powder storage tank, The powder pushing mechanism includes a power input mechanism, a first powder pushing piece and a second powder pushing piece. By setting the first powder pusher and the second powder pusher in the first powder storage tank and the second powder storage tank, when the power input mechanism drives the first powder pusher to move down, the partition will close the second powder storage tank , the powder flows out from the first powder groove under the thrust of the first powder pusher. When the power input mechanism drives the second powder pusher to move down, the partition plate closes the first powder storage tank, and the powder flows out from the second powder tank under the thrust of the second powder pusher. The powder flows out from the first powder outlet under the thrust of the first powder pusher or the second powder pusher, so it can not only improve the powder feeding efficiency, but also avoid the phenomenon of "bridging".

Description

technical field [0001] The invention relates to the technical field of 3D printing processing, in particular to a powder spreading device. Background technique [0002] 3D printing technology is a technology that accumulates materials layer by layer to manufacture solid workpieces. Compared with traditional material removal technology, it does not require tools and molds, and does not require multi-process processing. The production cycle is short and complex structures can be easily processed. artifacts. [0003] At present, in the field of 3D printing manufacturing, common powder spreading methods include scraper type and moving hopper type. Scraper-type powder spreading, the material is discharged at one end of the cylinder, and then the metal powder is pushed by the scraper to scrape from one end of the cylinder to the other. If this method is used to spread the powder, when the scraper moves too fast, the powder will be taken away by the scraper, resulting in uneven p...
