Recycling and regeneration device for FDM printing waste

Abstract

The invention relates to the technical field of FDM printing matter regeneration and recycling, in particular to a recycling and regeneration device for FDM printing waste. The device comprises a crushing device, a melting extrusion device, a pelletizing device and a collection box. The crushing device comprises a hopper, a heating wire net is arranged in the direction perpendicular to falling inthe hopper, a first discharge outlet is formed in the bottom of the hopper and located below the heating wire net, and the first discharge outlet is connected with a feed inlet of the melting extrusion device. When material flow passes through the heating wire net under the effect of gravity, the material part making contact with the wire net is rapidly molten and cut off, falls down from net grids, and falls into the feed inlet o the melting extrusion device through the discharge outlet. By means of the device, waste produced in the printing and fine processing process of FDM printing equipment is recycled, crushed, molten again and pelletized, brand new printing raw materials are obtained, great material waste is avoided, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of recycling FDM printed matter, in particular to a recycling device for FDM printing waste. Background technique [0002] With people's continuous exploration and innovation in the field of equipment manufacturing, 3D printing additive manufacturing has been widely concerned and promoted in various manufacturing fields, among which FDM 3D printing technology is one of the main methods of additive manufacturing. [0003] At present, FDM printing technology has developed rapidly in industrial production, medical and health industries, and its application is also different in different fields. In industrial production, larger parts are mainly formed. At present, there are mainly the following problems: (1) The raw materials for FDM molding are mainly thermoplastic materials, and the material cost is relatively high; Improve the molding efficiency, and the precision of the molded parts will be poor during fast...

AI Technical Summary

Problems solved by technology

In industrial production, larger parts are mainly formed. At present, there are mainly the following problems: (1) The raw materials for FDM molding are mainly thermoplastic materials, and the material cost is relatively high; Improve the molding efficiency, and the precision of the molded parts will be poor during fast printing, which needs to be reprocessed, and the processing and cutting amount is large; (3) Before starting to print new parts, the material in the printing head needs to be squeezed To ensure the material performance status of the processed parts, a certain amount of material is wasted; (4) During the printing process, due to warping in the design or printing process, the printing failed, which also caused a lot of waste of materials; (5) Some parts It is necessary to print the support structure, and printing the support structure with the materials of the printed parts will waste a lot of raw materials and increase the cost; (6) The existing printing materials are mainly thermoplastic materials, such as PLA, ABS, etc., and a large number of printed products are scrapped after use , if not effectively recycled and reused, it will cause certain pollution to the environment
