Waste recovery equipment and recovery method for 3D printing

Abstract

The invention relates to the technical field of waste recycling, in particular to waste recycling equipment for 3D printing and a recycling method.The equipment comprises a consumable extruder, the consumable extruder comprises a machine barrel, a screw rod, a heater, a nozzle, a filtering device and a driver, the screw rod is rotationally connected in the machine barrel, the driver is fixedly connected with the upper surface of the machine barrel, and the heater is arranged in the machine barrel; the filtering device is mounted between the nozzle and the machine barrel; a cover, a second cover plate and an annular filter screen are arranged, a controller controls a rotating shaft of a driver to rotate by 90 degrees, fan-shaped spaces in a vertical state are changed into a horizontal state, the fan-shaped spaces are cleaned by a worker by separating the cover from the second cover plate, meanwhile, the adjacent fan-shaped spaces are rotated to the position between a nozzle and a machine barrel, and the fan-shaped spaces are cleaned. Therefore, the annular filter screen in the fan-shaped space can normally filter the molten waste at any time, and the phenomenon that the working efficiency of waste recovery is reduced due to the fact that a worker needs to stop the machine and needs to detach the nozzle for cleaning is reduced.

Description

technical field [0001] The invention relates to the technical field of waste recycling, in particular to a waste recycling device and a recycling method for 3D printing. Background technique [0002] 3D printing refers to the technology based on digital model files, using bondable materials such as powdered metal or plastic, and constructing objects by layer-by-layer printing; waste refers to the residual materials or discarded models of 3D printing models. , by recycling waste materials and then preparing them into linear or powdered materials, so as to provide consumables for 3D printers to manufacture models. [0003] In the process of waste recycling, it is necessary to pour the chopped and dried waste into the consumable extruder, melt the waste through the heating device of the consumable extruder, and push through the threaded rod in the extruder to make The threaded rod drives the melted waste to move to the nozzle, and the width of the inner hole of the nozzle grad...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that the difficult-to-melt material in the melted waste will block the filter holes of the filter screen during the processing of the waste in the factory, which will affect the problem that the melted waste enters the nozzle through the filter screen; at the same time, it reduces the number of workers It needs to be shut down and the nozzle needs to be disassembled to clean the filter screen on the nozzle, which leads to the problem of reducing the efficiency of waste recycling; the invention proposes a waste recycling equipment and recycling method for 3D printing
