Problems solved by technology

[0003] The current 3D printers add a lot of powder to the storage tank on the 3D printer at one time when adding powder, and release it directly when it needs to be taken, but after all the powder is concentrated in the storage tank for a long time, The powder will stick together to form larger particle powder, which will flow to the printing platform when the powder is released, resulting in uneven laying of the powder, which will affect the printing quality of the product. In addition, in When the powder is released, the large particle powder is easy to block the feed port, and it needs to be dredged manually, which further reduces the production efficiency and increases the production cost of the product

Embodiment 1

[0030] see Figure 1-Figure 4 , a high-efficiency powder spreading type 3D printer, including a body 1. Further, the inner wall on one side of the body 1 is inclined to facilitate the discharge of the inflowing powder. The upper end of the body 1 is fixedly connected with a powder storage tank 2 through a connecting rod. The powder storage tank 2 The lower end is fixedly connected with a fixed plate 3, the inner wall of the powder storage tank 2 is rotatably connected with a rotating shaft 4, the side wall of the powder storage tank 2 is fixedly connected with a motor 5 through a connecting rod, the movable end of the motor 5 is fixedly connected with the side wall of the rotating shaft 4, and the side wall of the rotating shaft 4 The wall is uniformly distributed and fixedly connected with a plurality of stirring blades 6 along its axial direction, and a circular groove 7 is opened on the fixed plate 3, and the lower end of the circular groove 7 communicates with the upper end...

Embodiment 2

[0032] As a preferred solution in Embodiment 1, the dredging mechanism includes a plurality of fixed rods 12 uniformly distributed and fixedly connected to the inner wall of the feed port 11, and the side walls of the plurality of fixed rods 12 are slidably connected with thimbles 13, and the lower ends of the plurality of thimbles 13 are fixed. Connected with a magnetic ring 14, one of the stirring blades 6 is made of magnetic material, the feeding port 11 is set opposite to the stirring blade 6 made of magnetic material, and the lower end of the fixed rod 12 is fixedly connected with the upper end of the magnetic ring 14 through a return spring 15 , further, when the stirring blade 6 made of magnetic material is continuously skimmed above the feed port 11, the magnetic ring 14 is continuously reciprocatingly sliding up and down in the feed port 11 under the action of the magnetic attraction force and the elastic force of the return spring 15, The inside of the feed port 11 is c...

Embodiment 3

[0034] As yet another preferred solution in Embodiment 1, the first drive mechanism includes a cross column 16 rotatably connected to the side wall of the fixed plate 3, the side wall of the cross column 16 is fixedly connected with a sector gear 17, and one end of the cross bar 8 runs through the fixed plate 3 The side wall is also fixedly connected with a gear 18 meshing with the sector gear 17. Further, when the sector gear 17 rotates one turn, it drives the gear 18 to rotate a quarter turn, so that the material guide groove 10 can be intermittently discharged into the body 1. powder, the motor 5 is equipped with a third driving mechanism that drives the horizontal column 16 to rotate.

Abstract

The present invention provides a high-efficiency powder spreading type 3D printer, which includes a machine body, the upper end of the machine body is fixedly connected with a powder storage tank through a connecting rod, the lower end of the powder storage tank is fixedly connected with a fixing plate, and the inner wall of the powder storage tank is rotatably connected with a A rotating shaft, the side wall of the rotating shaft is uniformly distributed and fixedly connected with a plurality of stirring blades along its axial direction, a circular groove is opened on the fixed plate, and the lower end of the circular groove communicates with the upper end of the machine body. The invention stirs the powder in the storage tank through the rotation of the stirring blade, avoiding the formation of large particle powder after the powder accumulates for a long time, which affects the discharge and use of the powder. When the stirring blade is rotated, the stirring blade made of magnetic material is continuously Skimming over the feeding port, the magnetic ring continuously slides up and down in the feeding port under the action of the magnetic attraction force and the elastic force of the return spring, and continuously dredges the feeding port to facilitate the discharge of powder and avoid the blockage of the feeding port. , affecting production efficiency.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of 3D printers, in particular to an efficient powder-spreading 3D printer. Background technique [0002] 3D printers, also known as three-dimensional printers, are rapid prototyping equipment that construct three-dimensional entities by layer-by-layer printing based on digital model files. When using a 3D printer, it is necessary to lay powder materials on the printing table for printing. [0003] The current 3D printer adds a lot of powder to the storage tank on the 3D printer at one time when adding powder, and releases it directly when it needs to be taken, but after all the powder is concentrated in the storage tank for a long time, The powder will stick together to form larger particle powder, which will flow to the printing platform when the powder is released, resulting in uneven laying of the powder, which will affect the printing quality of the product. In addition, i...
