3D printer discharging mechanism convenient to disassemble and maintain

Abstract

The invention belongs to the technical field of 3D printer equipment, and particularly relates to a 3D printer discharging mechanism convenient to disassemble and maintain. The 3D printer discharging mechanism device comprises a first nozzle, a heating block, a throat pipe, a radiating pipe and a second nozzle; the throat pipe is of a tubular structure, the first nozzle and the heating block are connected to the lower end of the throat pipe in a sleeving mode, the first nozzle is located below the heating block, the second nozzle sequentially penetrates through the radiating pipe, the throat pipe and the heating block, and one end of the second nozzle is flush with one end of the first nozzle; one end, far away from the first nozzle, of the second nozzle is in communication with a discharge port of a feeding mechanism of the printer; and the heating block is further provided with two sets of first fixing assemblies and two sets of second fixing assemblies. By arranging the first fixing assemblies and the second fixing assemblies on the heating block, when the nozzle of the 3D printer is replaced or repaired through a power-on wire and a temperature sensing wire, the power-on wire and the temperature sensing wire are prevented from being pulled apart from the welding position.

Description

technical field [0001] The invention belongs to the technical field of 3D printer equipment, and in particular relates to a 3D printer discharge mechanism that is easy to disassemble and maintain. Background technique [0002] 3D printing 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 to manufacture three-dimensional objects by printing layers of bonded materials. [0003] The discharge mechanism is one of the most important parts in the 3D printer. Because the nozzles of the discharge mechanism often need to eject heated materials, they are easy to wear and block, and need frequent replacement and repair. At the same time, after the nozzle of the 3D printer is cooled, the remaining raw material in the nozzle is cooled to a solid state. Since it is far away from the heating block, this part of the raw material ...

AI Technical Summary

Problems solved by technology

[0003] The discharge mechanism is one of the most important parts of the 3D printer. Because the nozzle of the discharge mechanism often needs to spray heated materials, it is easy to wear and block, and requires frequent replacement and repair.

At the same time, after the nozzle of the 3D printer is cooled, the remaining raw material in the nozzle is cooled to a solid state. Since it is far away from the heating block, this part of the raw material is heated slowly, which consumes time and energy; The power line and temperature-sensing line on the battery fall off, which not only increases the difficulty of replacement and maintenance, but also increases the cost of maintenance.
