Autonomous winding mechanism for 3D printer filaments

Abstract

The invention discloses an independent winding mechanism for 3D printer linear consumables. The independent winding mechanism for the 3D printer linear consumables comprises a bracket with a fixed position, an expansion shaft is actively arranged on the bracket and can rotate around own axis; the expansion shaft is sleeved with a wire wrapping plate for collecting and winding a line body; an expansion guiding groove is formed in the expansion shaft and is perpendicular to the center axis of the expansion shaft and penetrates through the expansion shaft, an adjusting shaft is arranged in commonaxis of the expansion shaft and can rotate around own axis; an expansion block is matched with the expansion shaft in a sliding mode and placed at one side of the adjusting shaft and matched with theexpansion guiding groove; the adjusting shaft comprises a polished rod section located in the centre of the expansion shaft, and a pair of thread sections located at one side of the polished rod section; the pair of the thread sections and the expansion shaft are arranged in a coaxial line and the direction of turning of threads of the pair of the thread sections are inverse; pushing blocks are sleeved with the pair of the thread sections, the opposite ends of the pair of the pushing blocks are provided with a pushing end of a trapezoidal structure; and the expansion block contacts the pushing end of the pushing block and can receive thrust provided by the pushing block.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a system for recyclable 3D printer consumables ABS and PLA. Background technique [0002] 3D printing (3DP) is a kind 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. [0003] ABS (formerly known as acrylonitrile-butadiene-styrene copolymer) is a common material for household fused deposition (FDM) filaments, and PLA (commonly referred to as polylactic acid) is a biodegradable plastic that can be printed at 180 ~200°C. [0004] With the increasing popularity of 3D printing technology and its use in teaching, production, processing, and testing, images printed with ABS and PLA consume more raw materials. When the image has no value, the existing technology cannot The raw materials can only be recycled, and they can only be discarded....

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that 3D printer consumables ABS and PLA cannot be recycled in the prior art, the present invention designs a mechanism that includes melting of ABS and PLA consumables, extrusion of molten raw materials, wire arrangement, and wire winding. , which is suitable for teaching bases, factories and other places where 3D printers are often used, and is of great significance to the recycling of ABS and PLA consumables
