Abstract

The invention relates to the technical field of 3D printing, in particular to a stirring and crushing unit and a 3D printing waste recovery device. The stirring and crushing unit comprises a shell, arotating shaft and crushing assemblies. A feeding port and a discharging port are arranged on the shell. The rotating shaft is mounted in a vertical rotation manner. At least part of the rotating shaft extends into the shell. The number of the crushing assemblies is at least two. Each crushing assembly comprises a fixed cutter ring and a movable cutter ring which are used in cooperation. The fixedcutter ring is arranged on the inner wall of the shell. The movable cutter ring rotates along with the rotating shaft. The at least two crushing assemblies are arranged in an axially spaced manner. The working surfaces of one fixed cutter ring and the corresponding movable cutter ring are conical surfaces with a radial gap between; and the maximum radial gap and the minimum radial gap between thecutter rings of the at least two crushing assemblies sequentially narrow down downwards in the axial direction. The technical problem that in the prior art, particles obtained after waste is crushedare large in size, and subsequent processing is inconvenient to carry out is solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a stirring and pulverizing unit and a 3D printing waste recycling device. Background technique [0002] As 3D printing technology becomes more and more mature, its use and penetration rate is gradually increasing. More and more people use 3D printers to make supplies in their daily life, and the consumables used are also increasing rapidly. The FDM technology adopted by most daily printers on the market, its consumables are mainly acrylonitrile-butadiene-styrene plastic (ABS) and polylactic acid (PLA). At the same time, 3D printing waste such as defective products and scraps produced during the production process is also increasing rapidly, but the recycling and processing technology for these wastes is far from meeting people's needs. People usually only use 3D printing waste. You can choose to discard them. These discarded 3D printing waste not only waste 3D printing consu...
