fig. 2 is a cross-sectional view of a powder recycling bin of the automatic powder recycling device for 3D printing according to the invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1 to 2, an embodiment of the present invention provides an automatic powder recycling device for 3D printing, including a powder recycling bin 1, a recycling pipe opening 11 communicating with the inside of the powder recycling bin 1 is disposed at the bottom end of the powder recycling bin 1, and a powder recycling mechanism is disposed in the powder recycling bin 1 to guide the powder in the powder recycling bin 1 into the recycling pipe opening 11, and discharge the powder out of the powder recycling bin 1 through the recycling pipe opening 11. Meanwhile, the recycling pipe opening 11 is connected with the recycling powder pipe 2, the other end of the recycling powder pipe 2 is connected with the powder collector 4, so that the powder discharged out of the recycling powder barrel 1 can be introduced into the powder collector 4 through the recycling powder pipe 2 to be collected, and the powder of the recycling powder barrel 1 does not need to be poured into the powder collector 4 manually. And a driving part for conveying the powder in the recovery powder pipe 2 to the powder collector 4 is arranged on the recovery powder pipe 2, so that the speed of conveying the powder to the powder collector 4 is increased, and the probability of blocking the recovery powder pipe 2 by the powder can be reduced.
Specifically, the powder recovery mechanism comprises a rotating shaft 13 arranged inside the powder recovery barrel 1, a rotating plate 12 rotating around the rotating shaft 13 and a powder collecting port 14 arranged at the bottom of the powder recovery barrel 1, wherein the rotating shaft 13 is positioned at the bottom end of the rotating plate 12, and clamping plates are arranged on two sides of the rotating shaft 13 and clamped on the bottom surface of the rotating plate 12, so that the rotating shaft 13 is rotated to drive the rotating plate 12 to rotate; of course, there is no only one mode, and the rotating plate 12 may be rotated by fitting the rotating shaft 13 into the rotating plate 12, or by providing a gear mechanism or the like between the rotating shaft 13 and the rotating plate 12. Still be equipped with the control axis of rotation 13 moving controller 15 in retrieving powder bucket 1, at ordinary times, rotor plate 12 is located horizontal position, retrieve powder pipe 2 and collect the powder normally, when powder is carried to powder collector 4 in needing to retrieve powder pipe 2 in, make rotor plate 12 rotate downwards round axis of rotation 13 through control controller 15, the powder in this recovery powder bucket 1 can be along the downward flow of the inclined plane that rotor plate 12 formed, near the bottom of the inclined plane that rotor plate 12 formed is equipped with powder collection mouth 14 simultaneously, can let the powder in retrieving powder bucket 1 flow to in retrieving the mouth of pipe 11 through powder collection mouth 14.
