3D printing equipment with multiple feeding tubes

Abstract

The invention discloses 3D printing equipment with multiple feeding tubes. The 3D printing equipment comprises a mounting rack, a vertical moving mechanism, a horizontal moving mechanism, a printing head and a printing supporting mechanism, wherein the vertical moving mechanism comprises a first drive device, a lifting rod, a mounting plate and a positioning rod; the horizontal moving mechanism comprises a horizontal moving rod and a second drive mechanism; the printing head comprises a plurality of heating devices, a heat insulating device, a radiating device, a spray head, a spray nozzle and a plurality of feeding tubes; the heat insulating device is mounted above the heating devices; the radiating device is mounted above the heat insulating device; a feeding device is mounted at the upper ends of the feeding tubes; a closing valve is arranged on positions, corresponding to communication positions of the feeding tubes and the spray head, in the spray nozzle; the spray nozzle is detachably mounted at the lower end of the spray nozzle; and the printing supporting mechanism comprises a third drive device and a printing base. The 3D practical equipment with multiple feeding tubes can reduce vibration in a printing process, and can carry out color printing.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a multi-feed tube 3D printing device. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine 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. It is a cumulative manufacturing technology that creates three-dimensional objects by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the 3D printer, the machine will build the product layer by layer according to the program, and The product is printed out and ready for immediate use. 3D printers used to be used to make models in the fields of mold making, industrial design, etc., and are now gradually being used for direct manufacturing of some products, which can be used in jewelry, footwear, industrial d...

Problems solved by technology

[0003] The current 3D printing equipment is driven in a variety of ways. Existing 3D printing equipment usually includes horizontal tracks. The horizontal tracks include X tracks and Y tracks that are perpendicular to each other. 3D printing equipment uses multiple driving devices to drive the printing head to move in the horizontal and vertical directions to achieve printing. This method of movement requires high coordination between the various driving devices and it is difficult to avoid vibration of the printing head, which affects the printing quality. If the consumables are missing during the printing process of the existing 3D printing equipment, the operation of the 3D printing equipment needs to be stopped, and the printing will continue after the replacement of the consumables is completed, and the printing process of the current 3D printing equipment is quite cumbersome if it prints color products
