Detailed Description
Fig. 1 is a schematic structural diagram of a continuous 3D printing powder supply system according to an embodiment of the present application. Referring to fig. 1, the continuous 3D printing powder supply system generally comprises: store up powder jar 2, store up powder pipeline 7 temporarily, first butterfly valve 6, second butterfly valve 8, ejection of compact return bend 9, shop's powder mechanism 10 and removal guide rail 11.
Referring to fig. 1, the powder storage tank 2 has a powder outlet mechanism 3 at the bottom and a powder inlet mechanism 1 at the top. Generally, the powder storage tank 2 has a large capacity and can store a large amount of metal powder to be laid by the powder laying mechanism 10 before printing.
Referring to fig. 1, the temporary powder storage pipeline 7 is a straight pipeline with two communicated ends, a first butterfly valve 6 is arranged at the upper end of the temporary powder storage pipeline 7 and is connected with the powder discharging mechanism 3 of the powder storage tank 2 through a corrugated pipe 5, and a second butterfly valve 8 is arranged at the lower end of the temporary powder storage pipeline;
for the temporary powder storage pipeline 7 used for the initial use, firstly, the first butterfly valve 6 is opened, and the second butterfly valve 8 is in a closed state, so that the metal powder in the powder storage tank 2 enters the temporary powder storage pipeline 7 through the corrugated pipe 5 for temporary storage; after a certain amount of metal powder is stored in the temporary powder storage pipeline 7, the first butterfly valve 6 is closed, and the second butterfly valve 8 is opened, so that all the metal powder in the temporary powder storage pipeline 7 enters the discharge elbow 9. Therefore, the first butterfly valve 6 and the second butterfly valve 8 are always in the opposite use state.
The primary powder storage amount in the temporary powder storage pipeline 7 is 0.2-0.3L. When the primary powder storage amount of the temporary powder storage pipeline 7 is too low, the requirement of the powder spreading mechanism 10 is difficult to meet, powder needs to be replenished again, and the working efficiency is obviously reduced. When the primary powder storage amount of the temporary powder storage pipeline 7 is too high, powder is easily accumulated to cause blockage.
Referring to fig. 1, the discharge elbow 9 is arc-shaped, and the inlet of the discharge elbow is connected with the outlet of the temporary powder storage pipe 7. For receiving the metal powder dropped from the temporary powder storage duct 7. The reason why the metal powder is formed in the arc shape is to give a certain buffering action to the falling metal powder and to prevent a large amount of the metal powder from being accumulated and agglomerated when falling from the temporary powder storage duct 7.
Referring to fig. 1, the powder spreader is mounted on a moving guide rail 11 and is movable from one end of the moving guide rail 11 to the other end. When the powder spreading mechanism 10 is located at one end of the movable guide rail 11, the feeding hole of the powder spreading mechanism 10 is communicated with the discharging hole of the discharging bent pipe 9. Therefore, the powder spreading mechanism 10 can receive the metal powder flowing out through the discharge elbow 9, and then the metal powder moves from one end to the other end along the moving direction of the moving guide rail 11 to be uniformly spread. After the powder spreading is finished, the powder spreading mechanism 10 returns to the lower part of the discharging guide pipe again, so that the metal powder can be received next time.
In one embodiment of the present application, the discharging elbow 9 is fixed on one side of the powder spreading mechanism 10, and the size of the feeding hole of the discharging elbow 9 is larger than or equal to that of the discharging hole of the temporary powder storage pipeline 7, and when the powder spreading mechanism 10 is located at one end of the moving guide rail 11, the feeding hole of the discharging elbow 9 is located right below the temporary powder storage pipeline 7.
In another embodiment of the present application, the discharge elbow 9 is fixed below the temporary powder storage pipe 7, and the size of the discharge outlet is smaller than or equal to the size of the feed inlet of the powder spreading mechanism 10, and when the powder spreading mechanism 10 is located at one end of the moving guide rail 11, the discharge outlet of the discharge elbow 9 is inserted into the feed inlet of the powder spreading mechanism 10 or is in seamless butt joint with the feed inlet.
The continuous 3D printing powder supply system adopts the temporary powder storage pipeline 7 as metal powder, and the powder is sent a small amount of times by the transfer mechanism in the powder storage tank 2 to the powder spreading mechanism 10, so that the powder blockage is effectively avoided, the powder can be quantitatively conveyed to the printing equipment, and the efficient operation of powder spreading and printing is ensured.
This application has broken through among the prior art powder feeding link powder card and has hindered the difficult problem that leads to the printing process unstable, has also solved the powder simultaneously and can't effectively control the difficult problem of volume in the conveying link, under the stable prerequisite of guaranteeing to spread the powder and print, saves the time of overall pay-off in step.
The continuous 3D printing powder supply system comprises the following steps when in use:
(1) moving the powder storage tank 2 to a powder storage tank placing platform 4, detecting and ensuring that a powder feeding mechanism 1 of the powder storage tank 2 is in a closed state;
(2) tightly connecting the powder outlet mechanism 3 of the powder storage tank 2 with a first butterfly valve 6 through a corrugated pipe 5 to ensure that the first butterfly valve 6 is in a closed state, and manually opening the powder outlet mechanism 3 of the powder storage tank 2;
(3) when the printing system operates, the second butterfly valve 8 is closed, the first butterfly valve 6 is opened, the metal powder automatically falls into the temporary powder storage pipeline 7, and when the metal powder in the temporary powder storage pipeline 7 reaches the target amount, the first butterfly valve 6 is closed;
(4) opening a second butterfly valve 8 to allow the metal powder in the temporary powder storage pipeline 7 to completely enter the powder spreading mechanism 10 through a discharge elbow 9;
(5) when the powder spreading mechanism 10 drops down quantitative powder, the second butterfly valve 8 is closed, the steps (2) to (4) are repeated again, and meanwhile, the powder spreading mechanism 10 moves left and right on the movable guide rail 11 to spread the powder;
(6) when the powder stored in the powder paving mechanism 10 reaches the limit point, the powder paving mechanism 10 returns to the original position to receive the metal powder falling from the discharging elbow 9 for the next time.
