3D printer feeding device and feeding method thereof

Abstract

The invention relates to the technical field of feeding equipment, and discloses a 3D printer feeding device. The 3D printer feeding device comprises a feeding box, a connecting plate is fixedly connected with the bottom surface of the feeding box, movable blocks are movably clamped with the inner side of the connecting plate, and fixed plates are fixedly connected to the outer end surfaces of the movable blocks. According to the 3D printer feeding device and the feeding method thereof, a sliding groove is formed in the inner side face of the connecting plate, the connecting plate is clamped with the movable blocks through the sliding groove, the fixed plate is connected to the outer end faces of the movable blocks, a double-threaded rod is connected with the fixed plate in a threaded and sleeving mode, and a first gear sleeves one end of the double-threaded rod; and a motor is used for driving a second gear to rotate to achieve rotation of the first gear, then the two sets of movable blocks can move oppositely and reversely at the same time, the discharging caliber of a feeding box is changed, stable pushing air pressure is kept, meanwhile, the discharging amount is changed, the working stability of an air pump is improved, the material feeding stability is improved, and the using effect is good.

Description

technical field [0001] The invention relates to the technical field of feeding equipment, in particular to a feeding device and a feeding method for a 3D printer. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. 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. The working principle of 3D printers is basically the same as that of ordinary printers, except that the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with different "printing materials" such as metal, ceramics, plastics, sand, etc., which can be "printed" A device that produces real 3D objects. [0003] The feeding device of the existing 3D printer, in the process of use, because the width of the printing material sprayed out by the nozzle head is changed during the feeding pro...

AI Technical Summary

Problems solved by technology

[0003] The feeding device of the existing 3D printer, in the process of use, because the width of the printing material sprayed out by the nozzle head is changed during the feeding process, so as to meet the printing of different shapes and thicknesses, the existing method is usually changed. It is achieved by pushing out the air pressure, which requires frequent changes in the power of the pushing out air pump. The air supply of the air making pump cannot be kept stable, which affects the stability of the air pump and reduces the working life of the air pump. , the push-out air pressure is too small, reducing the push-out effect, and the use effect is not good

[0004] In addition, during the use of the existing 3D printer’s feeding device, because the air pump needs to inhale air to the outside when increasing the pushing air pressure, and there are a lot of impurities in the outside air, it is directly used to push the 3D printer without treatment. When the material is used, the impurities in the air are mixed in the material, which makes the printing structure mixed with impurities during the printing process, which affects the quality of the printed product, reduces the printing effect, and the use effect is not good

[0005] On the other hand, the feeding device of the existing 3D printer needs to transport the material to the feeding box through the connecting pipe during the printing process, and the feeding box moves with the nozzle during the feeding process, so that the fixed communication The connecting pipe twists during the movement of the feeding box, which reduces the actual flow area of ​​the connecting pipe. After twisting, the surface of the connecting pipe deforms violently, causing damage to the connecting pipe and the hidden danger of material leakage. The use effect is not good. good
