[0040] Please refer to Figure 1 and Figure 2 ​The utility model provides a semi -automatic metal powder filling machine, and the semi -automatic metal powder filling machine comprises a base 10, a sliding seat 20, a telescopic structure 30 and a filling assembly 40. The base 10 has a placing platform 11, a plurality of plug-in grooves 12 for inserting the cylindrical shell 50 are arranged on the placing platform 11 at intervals. Two guide columns 13 are arranged on the base 10 at intervals. The sliding seat 20 is slidably arranged on the two guide columns 13. The telescopic structure 30 can drive the sliding seat 20 to move up and down. The filling assembly 40 is arranged on the sliding seat 20 and has a plurality of injection parts corresponding to the plug-in grooves 12 one by one, each injection part can extend into the cylinder cavity of each cylindrical shell 50, and the filling assembly 40 can fill a certain amount of metal powder into the cylinder cavity of each cylindrical shell 50 through each injection part during the upward movement of the sliding seat 20.

[0041] Specifically, during use, the sliding seat 20 can be controlled to rise to a certain position as an initial position, and then the cylindrical shell 50 to be filled is sequentially placed into each plug-in groove 12. When the filling mode is started, the sliding seat 20 drives the filling assembly 40 to move downward, the injection part extends into the cylinder cavity of the cylindrical shell 50, and then the metal powder is injected into the cylindrical shell 50 when the sliding seat 20 drives the filling assembly 40 to rise, until the sliding seat 20 returns to the initial position, and the filling of the metal powder is completed.

[0042] Compared with the prior art, the plurality of plug-in grooves 12 arranged on the base 10 can ensure that the cylindrical shell 50 is inserted, so that the cylindrical shell 50 is arranged vertically and the opening is upward. The telescopic structure 30 can drive the sliding seat 20 to move up and down, and during the downward movement, each injection part can extend into each cylindrical shell 50, and during the upward movement, a certain amount of metal powder can be gradually filled into the cylindrical shell 50. This filling mode can effectively improve the production efficiency, save manpower and has high practicability.

[0043] In the embodiment, the injection part gradually fills the metal powder during the upward movement from the bottom of the cylinder cavity of the cylindrical shell 50, which can also avoid the dust formed by the metal powder from flowing into the air and enhance environmental protection.

[0044] In some embodiments, the filling assembly 40 can adopt the structure as shown in Figures 1 to 2 , and the structure is shown in Figures 1 to 2The packing assembly 40 includes a hopper 41, packing tubes 42, transfer funnels 43, and a metering transfer structure 44. The hopper 41 is fixed to a slide 20. Multiple packing tubes 42 are provided, each arranged vertically and fixed to the slide 20, with the top end of each tube connected to the slide 20. The packing tube 42 serves as the filling section. Multiple transfer funnels 43 are provided, each connected to the top end of a packing tube 42. Multiple metering transfer structures 44 are provided, each corresponding to a transfer funnel 43. One end of each metering transfer structure 44 is connected to the bottom of the hopper 41, and the other end is connected to the corresponding transfer funnel 43, enabling the metering transfer of metal powder from the hopper 41 to the transfer funnel 43.

[0045] The silo 41 ensures the storage of metal powder, and the quantitative transfer structures 44 transfer a fixed amount of metal powder to the transfer funnels 43, which in turn fill the cylindrical shells 50 through the filling tubes 42. This structure ensures the quantitative filling of metal powder, can adapt to cylindrical shells 50 of different sizes, and also improves production efficiency, making it highly practical.

[0046] It should be noted that during the filling process of the metal powder, the quantitative transfer structure 44 works simultaneously while the telescopic structure 30 drives the slide 20 to rise. The working time of the quantitative transfer structure 44 is less than or equal to the rising time of the slide 20, so as to avoid the metal powder remaining in the transfer funnel 43. This ensures that the transfer funnel 43 is empty after each filling, thus ensuring the next filling of metal powder.

[0047] In some embodiments, the above-described quantitative delivery structure 44 may employ, as follows: Figure 3 The structure shown. See also Figure 3 Each quantitative transfer structure 44 includes a transfer cylinder 441, a rotating shaft 442, a helical blade 443, and a driver 444. One end of the transfer cylinder 441 is connected to the bottom of the hopper 41, and the other end is connected to the corresponding intermediate transfer funnel 43. The rotating shaft 442 is coaxially arranged with the transfer cylinder 441, and one end is rotatably connected to the hopper 41. The helical blade 443 is located in the transfer cylinder 441 and is spirally wound on the rotating shaft 442. The driver 444 is fixed on the hopper 41 and is poweredly connected to the rotating shaft 442.

[0048] The spiral blades 443 in the transfer cylinder 441 are driven to rotate by the rotating shaft 442, thereby realizing the quantitative control of metal powder. At the same time, the spiral blades 443 can also prevent the metal powder in the transfer cylinder 441 from being introduced into the transfer funnel 43, further improving the quantitative control effect.

[0049] In the embodiment, the spiral blade 443 can also extend into the bin 41 to avoid the accumulation or blockage of the material at the bottom of the bin 41.

[0050] The driver 444 can be a servo motor.

The bottom end of the vertical shaft 451 extends into the outlet of the transfer funnel 43. The first bevel gear 452 is coaxially connected to the end of the rotating shaft 442 extending into the transfer funnel 43. The second bevel gear 453 is coaxially connected to the vertical shaft 451 and engaged with the first bevel gear 452. The disturbance pieces 454 are arranged in a ring shape at the bottom end of the vertical shaft 451.

[0055] In the embodiment, the transfer funnel 43 has an outlet at the bottom end, and the outlet is in communication with the top end of the filler tube 42. The top end of the transfer funnel 43 is detachably connected to a top cover, which can be screw-connected to avoid the overflow of the metal powder in the form of dust in the transfer funnel 43 and ensure the rotatable connection of the vertical shaft 451.

[0056] During the rotation of the rotating shaft 442, the first bevel gear 452 is driven to rotate, which in turn drives the second bevel gear 453 to rotate. The disturbance pieces 454 at the bottom end are driven to rotate by the vertical shaft 451, which can avoid the blockage or accumulation of the metal powder at the bottom end of the transfer funnel 43 and ensure the filling effect of the metal powder.

[0057] In some embodiments, the second bevel gear 453 can adopt the structure as shown in Figure 3 FIG. 4B. Referring to Figure 1 , the second bevel gear 453 is located above the first bevel gear 452, so as to avoid the metal powder derived from the transmission cylinder 441 from falling on the second bevel gear 453, thereby ensuring the stable entry of the metal powder into the transfer hopper 43.

[0058] In some embodiments, the telescopic structure 30 can adopt the structure as shown in Figure 1 FIG. 5B. Referring to ​ , the telescopic structure 30 is provided at least two, and each telescopic structure 30 is arranged in parallel and spaced apart.

[0059] The plurality of telescopic structures 30 can ensure the stable lifting of the sliding seat 20, and can also ensure the bearing of a larger load. The telescopic structure 30 can be one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0060] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application.
