[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0030] Combine Figures 1 to 4 As shown, an embodiment of the present invention provides a powder feeding device that is convenient for powder replacement, comprising:

[0031] Quick release powder cartridge assembly 1;

[0032] A powder discharge assembly 2, comprising a housing 21 and a turntable 22. The outlet of the quick-release powder cartridge assembly 1 is detachably connected to the housing 21. The turntable 22 is disposed within the housing 21 and is provided with an annular receiving groove 221 for receiving powder flowing from the quick-release powder cartridge assembly 1.

[0033] The driving motor 3 is adapted to drive the turntable 22 so that the powder in the annular containing groove 221 flows out through the powder outlet 211 provided on the housing 21 .

[0034] Specifically, in this embodiment, the quick-release powder barrel assembly 1 is detachably connected to the shell body 21, and a turntable 22 is provided inside the shell body 21. An annular receiving groove 221 is provided on the turntable 22. Powder is filled inside the quick-release powder barrel assembly 1, and the bottom of the quick-release powder barrel assembly 1 has an opening. When the quick-release powder barrel assembly 1 is connected to the shell body 21, the opening of the quick-release powder barrel assembly 1 is located above the annular receiving groove 221. When the powder flows out, it can enter the annular receiving groove 221. The driving motor 3 drives the turntable 22 to rotate, and brings the powder in the annular receiving groove 221 to the powder outlet 211 provided on the shell body 21, and the powder flows out through the powder outlet 211.

[0035] The quick-release powder cartridge assembly 1 comprises an upper cover 11, a powder cartridge 12, and a discharge flange 13. The upper cover 11 is mounted on the top of the powder cartridge 12, and the discharge flange 13 is mounted on the bottom of the cartridge 12, forming a cylindrical container for storing powder. The discharge flange 13 is detachably connected to the housing 21. To change powders, the cylindrical container can be removed by simply disassembling the discharge flange 13 from the housing 21. After removal, the remaining powder in the powder cartridge 12 can be directly poured out and replaced with new powder, or a new empty powder cartridge 12 can be installed and directly filled with new powder. This ensures convenient powder replacement and improves production efficiency.

[0036] Combine Figure 2 and Figure 3As shown, preferably, in this embodiment, the blanking flange 13 is provided with three connecting openings 131 evenly distributed along the circumference. It should be noted that the number of connecting openings 131 is not specifically limited. The blanking flange 13 is connected to the shell 21 through the connecting opening 131, and the connecting opening 131 is an open gap. During installation, screw on the connecting opening 131, rotate the blanking flange 13 clockwise, and the screw enters the smallest part of the connecting opening 131. Finally, tighten the screw, and the blanking flange 13 is fixedly connected to the shell 21. When disassembling, it is only necessary to loosen the screw, and then rotate the blanking flange 13 counterclockwise so that the screw leaves the smallest part of the connecting opening 131. The blanking flange 13 can then be removed directly without unscrewing the screw. This improves the convenience of changing powder.

[0037] Combine Figure 2 As shown, preferably, the powder feeding device that facilitates powder replacement further includes a transition flange 4, which is connected to the housing 21. The discharge flange 13 is connected to the transition flange 4 through a connecting opening 131. The lower portion of the transition flange 4 enters the housing 21 and is located above the annular receiving groove 221 provided on the turntable 22. The powder in the powder barrel 12 enters the transition flange 4 from the bottom opening of the discharge flange 13 and then flows from the transition flange 4 to the annular receiving groove 221. Since the transition flange 4 is connected to the housing 21 and the powder first enters the transition flange 4 and then flows from the transition flange 4 to the annular receiving groove 221, the weight of the powder in the powder barrel 12 will not directly act on the turntable 22 in the housing 21. This can prevent the powder from exerting a greater pressure on the turntable 22 when a large amount of metal powder is introduced into the powder barrel 12, thereby preventing the turntable 22 from being biased. This improves the stability of the turntable 22.

[0038] Combine Figures 4 to 6As shown, in this embodiment, the upper cover 11 includes a powder cartridge cover 111 and a connecting flange 112. The connecting flange 112 is used to connect the powder cartridge 12. The powder cartridge cover 111 is provided with three first annular bosses 1111 evenly distributed along the circumference. The connecting flange 112 is provided with three annular grooves 1121 evenly distributed along the circumference. A second annular boss 1122 is formed between two adjacent annular grooves 1121. The number of the first annular bosses 1111 corresponds to the number of the annular grooves 1121. The powder cartridge cover 111 and the connecting flange 112 are connected to each other. During installation, the three first annular bosses 1111 on the powder cartridge cover 111 correspond one-to-one with the three annular grooves 1121 on the connecting flange 112. The first annular bosses 1111 enter the annular grooves 1121 and, after entering, rotate the powder cartridge cover 111, causing the first annular bosses 1111, originally aligned with the annular grooves 1121, to rotate below the second annular bosses 1122. The upper portion of the first annular bosses 1111 abuts against the lower portion of the second annular bosses 1122, restricting the upward removal of the powder cartridge cover 111. To ensure a tight seal, a sealing groove is provided on the sidewall of the cylindrical cone within the powder cartridge cover 111, within which an O-ring is installed. It should be noted that the number of first annular bosses 1111, annular grooves 1121, and second annular bosses 1122 is not specifically limited; one or more of each may be provided.

[0039] Combine Figure 7 and Figure 8 As shown, a powder blocking component 5 is provided in the powder barrel 12, and the powder blocking component 5 includes a limiting piece 51, a connecting rod 52, a cone head 53 and a spring 54. The limiting piece 51 is installed on the top of the connecting rod 52, and the cone head 53 is installed at the bottom of the connecting rod 52. The cone head 53 can block the bottom opening of the discharge flange 13. A spring 54 is installed below the limiting piece 51. A limiting boss 1123 is provided on the side wall of the connecting flange 112. When there is no need to block the opening at the bottom of the discharge flange 13, the limiting piece 51 is supported on the limiting boss 1123, and when the opening at the bottom of the discharge flange 13 needs to be blocked, the limiting piece 51 is pushed downward from the gap between the limiting bosses 1123, and the cone head 53 also moves downward. After it is in place, the limiting piece 51 is rotated so that the limiting piece 51 abuts against the bottom of the limiting boss 1123. Due to the action of the spring 54, the cone head 53 fits tightly with the bottom opening of the discharge flange 13. At this time, when the discharge flange 13 is removed, the powder in the powder tube 12 will not flow out from the bottom opening of the discharge flange 13.

[0040] In this embodiment, during use, gas needs to be introduced into the shell 21 and the top of the powder barrel 12, so that the powder in the powder barrel 12 not only flows downward under the action of gravity, but the pressure of the gas can also press the powder out, thereby ensuring the stability of powder discharge. The purpose of introducing gas into the shell 21 is to blow the powder out from the powder outlet 211 provided on the shell 21 under the action of the positive pressure in the shell 21.

[0041] Another embodiment of the present invention provides a powder feeding device, including the powder feeding device that is convenient for powder change, which can improve the convenience of powder change and improve production efficiency.

[0042] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
