Embodiment Construction

[0030] Such as Figure 1-4 As shown, a raw material premixing device for 3D printing provided by the present invention includes a support frame 1, a stirring bucket 2, a stirring mechanism 3, a raw material preset mechanism 4, a rotating mechanism 5, a pre-stirring structure 6, a mounting frame 7 and an upper Material device 8.

[0031] Among them, such as Figure 1-3 As shown, the mixing bucket adopts the shape of a square bucket cup. The mixing bucket includes a trapezoidal side plate 21 and a square top plate 22. A conical discharge hopper 24 is installed at the lower end of the mixing bucket. The stirring mechanism is installed on the On the stirring bucket, the stirring mechanism includes a stirring motor 31 fixed on the square top plate, a stirring shaft 32 extending into the stirring bucket, and a stirring rod 33 connected to the stirring shaft. The shaft 32 and the stirring rod 33 extend into the conical discharge hopper 24, and a pneumatic butterfly valve is install...

Abstract

The invention discloses a raw material premixing device for 3D printing, and relates to the technical field of material processing.The raw material premixing device for 3D printing comprises a supporting frame and a stirring hopper, the stirring hopper comprises a trapezoidal side plate and a square top plate, and the four directions of the square top plate are each connected with a raw material presetting mechanism; the raw material presetting mechanism comprises a feeding hopper, a square box and a conveying auger, a feeding hole and a discharging hole are formed in the top face of one end of the square box and the bottom face of the other end of the square box respectively, and the conveying auger comprises a motor and an auger arranged in the length direction of the square box. And the feeding holes in the four square boxes are distributed in a rectangular shape above the square top plate. Raw materials are fed into the raw material presetting mechanism one by one through the feeding hopper in advance, all the raw materials are synchronously fed into the stirring hopper through synchronous rotation of the raw material presetting mechanism, and then the raw materials are stirred through the stirring rod, so that the stirring uniformity of the raw materials is improved.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a raw material premixing device for 3D printing. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Adhesive materials need to go through multiple steps during production, including raw material reaction, and raw material mixing is often required before the raw material reaction. [0003] The current mixing method is to put the raw materials into the mixing bucket one by one and mix them by stirring. This has the following disadvantages: because the raw materials are added one by one, the raw materials added first after stirring are concentrated in the lower part, and the materials added later are concentrated in the upper part. There may ...
