Background

3D printers (3 dprings) are also known as three-dimensional printers, which are devices that can "print" real 3D objects. The 3D printing technology is also called additive manufacturing technology, which is an advanced manufacturing technology called rapid prototyping in China. The essential principle is as follows: discretization and stacking, namely, under the assistance of a computer, slicing the solid model, converting the manufacturing of the three-dimensional solid into stacking of two-dimensional layers and continuous superposition along the forming direction, and finally realizing the manufacturing of the three-dimensional solid. Compared with the traditional manufacturing method, the 3D printing method has the advantages of short manufacturing period, no limitation of part complexity in forming, material saving, energy saving and the like.

When the 3D printer is printing, need use to print the powder, use the powder box splendid attire to print the powder at present usually, if do not use this 3D printer to print for a long time, the easy caking of the powder of printing in the powder box of 3D printer becomes to stick together, and such powder of printing can't continue to use again, needs to clear up such powder of printing and puts into new the powder of printing again. At present, the powder cleaning mode is that the powder box is taken out manually, the agglomerated printing powder in the powder box is knocked out, the printing powder is poured out, and the powder box is cleaned by using a brush, so that the efficiency is lower.

SUMMERY OF THE UTILITY MODEL

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "secured to" another element, it can be directly connected to the other element or intervening elements may also be present.

In the present invention, unless otherwise specified, the terms of orientation such as "up, down, left, and right" used generally refer to up, down, left, and right as shown in fig. 1. "inner and outer" refer to the inner and outer portions of a particular contour. "distal and proximal" refer to distal and proximal relative to a component.

As shown in fig. 1, an embodiment of the utility model provides a clear powder device of 3D printer, this clear powder device of 3D printer includes mount 1, sliding frame 2, connecting plate 3, two cowl 4, a plurality of tooth post 5, gear 6, pivot 7, motor, scraper blade 8, whitewashes 9.

Mount 1 fixed connection is on the 3D printer, and optionally, mount 1 passes through the screw connection on the 3D printer, or mount 1 welds on the 3D printer. And the fixing frame 1 is positioned above the powder box 10 of the 3D printer, and sliding ports are arranged at two ends of the fixing frame 1.

The two ends of the sliding frame 2 are fixedly provided with the sliding rods 1a, and the sliding frame 2 is connected to the fixing frame 1 through the sliding rods 1a at the two ends in a sliding manner, so that the sliding frame 2 can slide left and right on the fixing frame 1. Gear 6 and the one end fixed connection of pivot 7, the other end of pivot 7 rotates the center of connecting at mount 1, and the fuselage fixed connection of motor is on mount 1, the output shaft and the pivot 7 fixed connection of motor, and like this, the output shaft of motor can drive gear 6 and rotate.

Sliding connection about 3 on the connecting plate slides frame 2, and the top fixed connection of scraper blade 8 and rendering 9 is at the lower extreme of connecting plate 3, and two cowl 4 fixed connection are on connecting plate 3, and two cowl 4 set up relatively, and a plurality of tooth post 5 set firmly on connecting plate 3, and a plurality of tooth post 5 evenly distributed is between two cowl 4, and the tooth and the meshing of a plurality of tooth post 5 of gear 6 mutually. Like this, when the motor drives gear 6 and rotates, tooth post 5 can be stirred to gear 6, make connecting plate 3 with 5 fixed connection of tooth post receive the ascending power in left right direction, and then drive sliding frame 2 and slide on mount 1, stir all tooth posts 5 backs when gear 6, under the effect of tooth post 5 is stirred to cowl 4 and gear 6, can drive connecting plate 3 and change position from top to bottom in sliding frame 2, and then gear 6 continues to drive sliding frame 2 and slides in the horizontal direction, then connecting plate 3 continues the position about the conversion.

Alternatively, the squeegee 8 is disposed on the right side of the brush 9 when the gear 6 is rotated counterclockwise, and the squeegee 8 is disposed on the left side of the brush 9 when the gear 6 is rotated clockwise.
