[0051] Specifically, in this embodiment, 7 workstations are evenly arranged inside the rotary silo 33, and 7 metal pipes can be placed at one time. The powder receiving funnel 34 is placed on any workstation of the rotary silo 33 when not loading powder.

[0056] Exemplarily, the rotary lifting mechanism 5 includes: a first mounting plate 501 , on which a first slide rail 502 and a third mounting plate 509 are arranged.

[0060] Exemplarily, the eccentric roller 508 is made of polyurethane, and the centering roller 511 is made of nylon.

[0061] Exemplarily, the tamping rod actuator 6 includes: a fourth mounting plate 61, a second slide rail 62 is provided on the fourth mounting plate 61, a second slider 63 is provided on the second slide rail 62, a slider tamping rod connecting piece 64 is provided on the second slider 63, a tamping rod 65 is provided on the slider tamping rod connecting piece 64, and a counterweight block 66 is provided on the tamping rod 65.

[0062] Specifically, the powder density of the metal powder can be adjusted by adjusting the number of the counterweight blocks 66 .

[0063] like Fig. 9 As shown, the embodiment of the present application also provides a method for using a multi-station automatic powder loading device for superconducting wires, comprising the following steps: Step 1: placing metal powder on the powder feeding actuator 4.

[0064] Step 2: placing a plurality of metal pipes in the rotating bin mechanism 3.

[0065] Step three, the control system 2 controls the powder delivery actuator 4 to deliver the metal powder to the inside of the metal pipe at the powder loading station.

[0066] Step 4: The control system 2 controls the rotating lifting mechanism 5 to drive the tamping rod actuator 6 to tamp the metal powder inside the metal pipe at the powder loading station.

[0067] Step 5: When the metal pipes at the powder loading station are completely loaded with powder, the control system 2 controls the rotating bin mechanism 3 to rotate the metal pipes that are not loaded with powder to the powder loading station for loading with powder.

[0068] Specifically, in this embodiment, in step one, the metal powder is placed in the powder silo 403 of the powder feeding actuator 4. Before placing the metal powder, check whether the interior of the powder silo 403 is clean to prevent impurities from entering the metal pipe along with the metal powder, resulting in unqualified material performance; and check whether the valve 404 of the powder feeding actuator 4 is in a closed state to prevent the metal powder from leaking from the powder silo 403 into the frame 1 in advance when filling the metal powder.

[0069] In this embodiment, in step 2, 7 metal pipes are sequentially placed in 7 stations of the rotary bin 33 of the rotary bin mechanism 3, and the powder receiving funnel 34 is placed on the upper end of one of the metal pipes.

[0070] Specifically, before placing the metal pipes at the workstation, the powder receiving funnel 34 is first taken out from the workstation of the rotating silo 33, then the tamping rod 65 is lifted, and the second motor 512 is controlled to rotate by jogging, and the tamping rod 65 is clamped by the joint action of the eccentric roller 508, the centering roller 511 and the spring 506; after the tamping rod 65 is clamped, the electric rotating platform 31 is controlled by jogging again to place the 7 metal pipes in the 7 workstations of the rotating silo 33 of the rotating silo mechanism 3 in sequence, and after all the metal pipes are placed, the powder receiving funnel 34 is placed on the upper end of one of the metal pipes, and then the electric rotating platform 31 is continuously controlled by jogging to rotate the workstation where the metal pipes are placed with the powder receiving funnel 34 to the bottom of the tamping rod 65 (i.e., the powder loading workstation); the second motor 512 is controlled by jogging again to make the tamping rod 65 fall into the metal pipe.

[0071] In this embodiment, in step three, the valve 404 is opened and the first motor 408 is started. After the first motor 408 is started, the powder feeding rod 410 is driven to rotate through the coupling 409, so that the metal powder in the powder silo 403 slides out from the spiral pattern of the powder feeding rod 410, and is evenly fed to the powder receiving funnel 34 of the rotating silo mechanism 3 through the material guide pipe 405, and then evenly fed to the metal pipe.

[0072] In the present embodiment, in step 4, the second motor 512 is started. After the second motor 512 is started, the eccentric roller 508 is driven to rotate by the eccentric roller shaft 507, and the ramming rod 65 is driven to be lifted and dropped under the joint action of the eccentric roller 508, the centering roller 511 and the spring 506, so that the metal powder inside the metal pipe of the powder loading station is compacted. In the present embodiment, the speed of the second motor 512 is set to 600r / min. If the speed of the second motor 512 is too fast, it will cause the ramming rod 65 to have only a lifting action but no descending action. With the filling of the metal powder, the ramming rod 65 will gradually rise with the second slider 63. When the metal powder is filled to the specified height position of the metal pipe, the first motor 408 and the valve 404 are closed, and the second motor 512 is changed to be inching controlled. Under the joint action of the eccentric roller 508, the centering roller 511 and the spring 506, the ramming rod 65 is proposed from the metal pipe, and then the second motor 512 is closed.

[0073] In this embodiment, in step five, when the powder filling of the metal tube at the powder filling station is completed, the second motor 512 is turned off, the powder receiving funnel 34 is taken out and placed on the upper end of a metal tube that is not filled with powder, and then the electric rotating platform 31 is started, the metal tube with the powder receiving funnel 34 is rotated to the bottom of the tamping rod 65, and the second motor 512 is controlled by jog to make the tamping rod 65 fall into the metal tube; then the valve 404 is opened, the first motor 408 and the second motor 512 are started, and the metal powder is filled into the metal tube and tamped; after the metal tube is filled with powder, the above-mentioned actions are repeated until all the 7 metal tubes in the rotating silo 33 are filled with powder; the power is cut off, and the powder silo 403, the powder receiving funnel 34, the tamping rod 65 and the scattered metal powder in the frame 1 are cleaned up for next use.

[0074] The embodiment of the present application realizes automatic powder feeding, automatic tamping and automatic station replacement by setting up a rotating bin mechanism 3, a powder feeding actuator 4, a rotating lifting mechanism 5 and a tamping rod actuator 6, and controlling the operation and linkage of each mechanism through a control system 2, thereby improving the degree of automation, powder loading uniformity and powder loading density of metal pipes, thereby improving the production efficiency and quality of superconducting wires.

[0075] The proposed rotating silo 33 has several stations for placing metal pipes evenly arranged inside. The diameter of each station is larger than the diameter of the metal pipe, which can ensure that the metal pipe can be smoothly placed and positioned at the station inside the rotating silo 33, and realize continuous powder loading of multiple metal pipes.

[0076] The proposed eccentric roller 508, centering roller 511 and spring 506 can drive the tamping rod 65 to be lifted and lowered through the cooperation among the eccentric roller 508, centering roller 511 and spring 506, and make the height of the tamping rod 65 remain consistent each time it is lifted and lowered.

[0077] The proposed eccentric roller 508 is made of polyurethane, and the centering roller 511 is made of nylon, which can effectively prevent the tamping rod 65 from shifting and contacting the inner wall of the metal pipe during the lifting and falling process, thereby avoiding scratching the inner wall of the metal pipe.

[0078] The proposed tamping rod 65 is provided with a counterweight block 66 , and the operator can adjust the number of the counterweight blocks 66 according to the overall weight of the metal pipe after powder filling, so as to further improve the powder filling density.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0080] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
