3D (three-dimensional) printer silk material conveying mechanism and silk feeding method thereof

Abstract

The invention discloses a 3D (three-dimensional) printer silk material conveying mechanism. The 3D printer silk material conveying mechanism is characterized in that a silk material used for providingsilk to a nozzle is placed in a silk material box, the silk material is conveyed to the nozzle through a power system, and the power system comprises a silk material pushing device close to one end of the silk material box, a silk material pulling device close to one end of the nozzle and a silk material buffer device arranged between the silk material pushing device and the silk material pullingdevice. A silk feeding method includes that the silk material pushing device stops running after pushing a segment of the silk material to the silk material buffer device, the silk material pulling device continuously runs and pulls the silk material, and when the silk material in the silk material buffer device is tightened, the silk material pushing device continuously pushes the segment of thesilk material to the silk material buffer device. According to the 3D printer silk material conveying mechanism, the silk material buffer device is arranged between the silk material pushing device and the silk material pulling device, the silk material pushing device discontinuously provides pushing force, the silk material pulling device continuously provides pulling force, the silk material pushing device and the silk material pulling device can continuously output silk without need for synchronously moving, and printing quality is improved.

Description

technical field [0001] The invention belongs to the field of 3D printers, and in particular relates to a 3D printer wire material transmission mechanism and a wire feeding method thereof. Background technique [0002] The FDM (Fused Deposition) 3D printer heats the print nozzle at high temperature to melt the filament and deposit it on the printing platform. When the molten filament contacts the printing platform, it is cooled and condenses rapidly, and the print nozzle deposits the filament layer by layer along the set printing path. onto the printing platform to construct a model with a three-dimensional structure. [0003] The filament box of a large FDM 3D printer is installed at the bottom of the 3D printer, and the nozzle of the printer is installed on the top of the 3D printer. The filament needs to be driven by a motor to print layer by layer on the printing platform. Usually the motor is installed in the nozzle of the printer, but due to the large size of the large...

AI Technical Summary

Problems solved by technology

[0004] However, setting two motors in the 3D printer to pull the filament will encounter the following problems: the two motors must operate synchronously. If the two motors do not operate synchronously, there will be problems with the filament output, resulting in unstable printing, and may even cause printing problems. fail
