Intelligent 3D printer convenient to move and free from wire drawing

Abstract

The invention relates to an intelligent 3D printer convenient to move and free from wire drawing. The intelligent 3D printer comprises a nozzle and two moving-supporting units. Each moving-supporting unit comprises a second driving motor and two moving-supporting assemblies, and the two moving-supporting assemblies are correspondingly arranged on the two sides of the second driving motor; each moving-supporting assembly comprises a buffer block, a second driving shaft, a translation block, a first connecting rod and a moving unit; each moving unit comprises a supporting rod, a hinging block and a pulley; a heating ring and a lifting assembly are arranged in the nozzle; and the lifting assembly comprises a first side rod, a third driving motor, a driving gear, a lifting rod and a copper pipe. The intelligent 3D printer has the advantages that the copper pipe and a material arranged on the periphery of the copper pipe are driven by the lifting assembly in the nozzle to move up during a material return process, thereby avoiding the occurrence of wire drawing and guaranteeing the attractiveness of a printed model; and furthermore, the movement of printing equipment can be facilitated when the printing equipment is supported by the moving-supporting units arranged on the two sides of a base, thereby improving the practicability of the intelligent 3D printer.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to an intelligent 3D printer that is easy to move and has no wire drawing. 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] When the existing 3D printer is printing, if the gap between the object of the printed model and the object is very close, for example, in the gap of 1mm to 5mm, there will be a lot of wires at the junction of the two objects, which will greatly affect the appearance of the printed model , after the printin...

Problems solved by technology

[0003] When the existing 3D printer is printing, if the gap between the object of the printed model and the object is very close, for example, in the gap of 1mm to 5mm, there will be a lot of wires at the junction of the two objects, which will greatly affect the appearance of the printed model , after the printing is completed, it needs to be processed with a knife. This kind of phenomenon is usually called wire drawing. In order to prevent wire drawing between objects, the printer usually adopts the method of returning materials during the printing process, that is, after the first object is printed, The material will be sucked back by the way of material return to prevent the heated material from flowing out of the nozzle, but even so, due to the large space of the nozzle of the nozzle, the residual material heated on the inner wall of the nozzle is easy to flow out of the nozzle, resulting in inability to completely To solve the problem of wire drawing, not only that, but the existing 3D printers are generally heavy. After the placement is completed, when the 3D printer needs to be moved and carried, people usually need to spend a lot of effort to realize its position. During the transportation, it is also easy Due to the negligence of personnel, the printer fell to the ground and damaged the equipment, resulting in a reduction in the practicability of the equipment
