A 3D printer storage unit

Abstract

The invention belongs to the technical field of 3D printing equipment, and particularly relates to a material storage unit of a 3D printer. The material storage unit comprises a rubber bag, a feed inlet, a discharge pipe, a discharge valve, a conveying motor, an upper supporting plate, a spiral stirring shaft, a lower supporting plate, slide blocks and a fixing frame, wherein the slide blocks arecorrespondingly arranged at the upper end and the lower end of the fixing frame, one slide block is connected to the right end of the upper supporting plate through a connecting rod, and the other slide block is connected to the right end of the lower supporting plate; the rubber bag is arranged between the upper supporting plate and the lower supporting plate, the feed inlet is formed in the leftupper end of the rubber bag, and the conveying motor is fixedly installed on the upper supporting plate; the spiral stirring shaft is rotatably installed on the conveying motor, and the discharge pipe is fixedly installed at the lower end of the rubber bag; and the discharge valve is connected in series with the discharge pipe; the rubber bag expands when raw materials enter from the feed inlet,the rubber bag contracts when the discharge valve is opened for discharging; and the raw materials are not prone to adhering to the inner wall of the rubber bag, the utilization rate of the raw materials is effectively improved, the raw materials are stirred through the spiral stirring shaft, the solidification of the raw materials is prevented, gas in the raw materials is discharged, and the printing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and specifically relates to a material storage unit of a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin lay...

Afterwards, the mold tray drops a very small distance for the next layer to be stacked up. This kind of printing uses the storage unit to store the liquid raw materials required for printing. In reality, the conventional storage unit is mostly made of hard materials. Raw materials are easy to adhere to the inner wall, resulting in waste of liquid raw materials, increasing the cost of use, and solidifying on the inner wall of the storage unit after cooling, increasing the working time for cleaning
