Feeding system of 3D printer

Abstract

The invention belongs to the technical field of 3D printing equipment, in particular to a feeding system of a 3D printer. The feeding system of the 3D printer comprises an upper supporting plate, a lower supporting plate, a water drop-type balloon, a set of mounting plates, motors, lead screws, first sliding blocks, sliding rings, a feeding pipe, a discharging pipe and a control valve. The feedingpipe is arranged at the top of the water drop-type balloon. The discharging pipe is arranged at the bottom of the water drop-type balloon. The control valve is connected to the discharging pipe in series. The upper supporting plate is fixedly connected to the outer side of the top of the water drop-type balloon. The set of mounting plates are arranged on the water drop-type balloon in the circumferential direction. The two ends of each mounting plate are separately connected with the upper supporting plate and the lower supporting plate. The lead screws are arranged on the inner sides of themounting plates. The motors are arranged at one ends of the lead screws. The first sliding blocks are screwed on the lead screws in the axial direction. The sliding rings are arranged on the water drop-type balloon in the circumferential direction. The outer sides of the sliding rings are connected with the first sliding blocks through connecting rods. In the feeding process, the motors rotates forwards or reversely to control the first sliding blocks to slide up and down on the lead screws, so that the water drop-type balloon is circularly squeezed up and down by the sliding rings to increasethe feeding speed of liquid raw materials in the water drop-type balloon, and accordingly, the feeding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, in particular to a 3D printer feeding system. 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 layers, and there are vari...

Afterwards, the mold tray is lowered by a very small distance for the next layer to be stacked up. The feeding system of conventional 3D printers usually uses the fluidity of the liquid material itself to achieve printing feeding through pipelines. The feeding efficiency of this feeding method depends on Due to the viscosity of liquid raw materials, the feeding efficiency is low for raw materials with high viscosity, which affects the effect of 3D printing
