Efficient 3D printer with anti-blocking and automatic adjusting functions

Abstract

The invention relates to an efficient 3D printer with anti-blocking and automatic adjusting functions. The efficient 3D printer comprises a base, a printing platform, a top plate, a material disc, a wire feeding pipe and two lifting units. A printing mechanism comprises a movable plate, a printing unit, a flow guiding unit and a dredging unit. The printing unit comprises a rotating unit, a first sprayer, a second sprayer, a blocking pipe and two material conveying pipes. A blocking mechanism is arranged in the blocking pipe. The dredging unit comprises a fixing rod, a driving unit, an inserting rod, a lifting rod and a bottom rod. The flow guiding unit comprises an air pump, an air pipe, an air cylinder, a piston and a heating pipe. According to the efficient 3D printer with the anti-blocking and automatic adjusting functions, the first sprayer and the second sprayer are flexibly switched through the rotating unit, the printing efficiency can be improved, the printing precision can be guaranteed, more than that, the driving unit drives a lifting frame and the inserting rod to move in the vertical direction back and forth, the first sprayer and the second sprayer are dredged, and the blocking phenomenon generated during printing is avoided.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to an anti-clogging and high-efficiency 3D printer with automatic adjustment function. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. Layers of bonded material are used to create three-dimensional objects. At this stage, 3D printers are used to manufacture products. Objects are constructed by printing layer by layer, and data and raw materials are put into the 3D printer. The machine will manufacture products layer by layer according to the program. [0003] Existing 3D printers are usually equipped with a print nozzle, usually the diameter of the print nozzle is 0.4mm, since there is only one print nozzle and the diameter of the nozzle is fixed, when printing a certain structure with the same area, it is necessary to move back and forth th...

Problems solved by technology

[0003] Existing 3D printers are usually equipped with a print nozzle, usually the diameter of the print nozzle is 0.4mm, since there is only one print nozzle and the diameter of the nozzle is fixed, when printing a certain structure with the same area, it is necessary to move back and forth through the nozzle Multi-point printing will result in low printing efficiency. Not only that, during the printing process, due to impurities inside the nozzle, it will usually cause the nozzle to be blocked, resulting in the nozzle being unable to extrude the material for printing. At this time, it is necessary to print the nozzle. Unblock or replace the nozzle, which will prolong the printing time and further affect the printing efficiency
