Problems solved by technology
[0004] The fixed feeding device makes the motor drive the driving wheel to rotate through a complex mechanical mechanism, and at the same time drives the material pressed on the driving wheel to realize wire feeding, but this feeding device has high requirements for the assembly process and cannot adapt to different Feeding requirements for large and small silk threads, it is also cumbersome to replace a single roll of silk thread after use, and it is not conducive to the printer to print products of different materials
[0005] The fine-tuning (self-adaptive) feeding device between cells can actively adapt to the diameter of the material in the cell while realizing the feeding, the mechanical structure is more complicated, and the processing cost is high. Although it is an adaptive feeding device, the device is easy to force the wire Unevenness causes problems such as slow wire movement, slippage of the wire rod, and uneven extrusion force, which lead to the failure of the normal use of the nozzle
[0006] In addition to the above-mentioned problems, since the current raw materials are usually stored in rolls and wound on the drum, there will inevitably be wrinkles during the storage process. When the wrinkle angle is large, it is easy to cause the wire to get stuck at the position of the nozzle, hindering the Nozzle works normally

Embodiment Construction
[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0038] Such as figure 1 and figure 2Shown is a schematic diagram of the structure of the present invention installed on a 3D printer. Since the working principle of the 3D printer is to stack products layer by layer along the Z axis, the 3D printers are all provided with vertical bars perpendicular to the work platform, and the two The ejector rod connected by two vertical rods, in some simple 3D printers, there is only a roller frame on the ejector rod, the roller frame is made...

The invention relates to the technical field of 3D printers, in particular to a raw material conveying device for a 3D printer. The raw material conveying device comprises a printer body, a mounting frame, a roller and a motor, wherein the mounting frame, the roller and the motor are mounted on a top rod of the printer body, and a repair module for smoothing folds of a filament is arranged on the mounting frame; the filament wound on the roller enters a traction module composed of the motor, a fixing frame and a floating plate after being smoothened by the repair module, the filament is finally guided into a spray head under the guidance of the traction module, and a brake rod for emergently suspending operation of the traction module is further installed on the fixing frame. In the traction module, through cooperation of the floating plate and an inserting strip, a gap between a driving wheel and a driven wheel can be flexibly adjusted, sufficient friction force is provided for traction of the filament, the situation that the filament moves slowly and slips due to uneven stress during traction of the filament is avoided, the device can be suitable for machining of filaments of various sizes, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of 3D printers, in particular to a material conveying device for 3D printers. Background technique [0002] Ordinary printers used in daily life can print flat objects designed by computers, and the so-called 3D printers are basically the same as ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while the printing materials used in 3D printers The most common printing materials are metals, ceramics, plastics, sand, etc., which are real raw materials. After the printer is connected to the computer, the "printing materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer can be turned into kind. [0003] At present, 3D printing materials mainly include polymer materials, metal materials, ceramic materials and composite materials, etc. ABS materials have become the preferred...
