[0021] Please see Figures 1 to 3 This utility model provides a single-head powder filling device 1000, including: a mounting frame 1 connected to the machine, a filling component 2 disposed below the mounting frame 1, and a drive component 3 disposed above the mounting frame 1. The filling component 2 includes a filling chamber 21 that gradually narrows at the bottom and a stirring mechanism 22 extending into the filling chamber 21.

[0022] Specifically, the stirring mechanism 22 includes a lifting stirring rod 221 located in the filling chamber 21. The shape of the end of the stirring rod 221 near the bottom of the filling chamber 21 is consistent with the shape of the inner wall of the bottom of the filling chamber 21.

[0023] Furthermore, the output end of the drive assembly 3 is connected to the stirring rod 221 and drives the stirring rod 221 to move up and down. The drive assembly 3 includes a lifting mechanism 31 that drives the stirring rod 221 to move up and down.

[0024] By designing a lifting and lowering stirring rod 221 within the filling chamber 21, the powder can be effectively prevented from condensing in the upper and middle parts of the filling chamber 21. Simultaneously, the design of the stirring rod 221's end facing the bottom of the filling chamber 21 aligning with the inner wall of the bottom of the filling chamber 21 avoids interference between the stirring rod 221 and the inner wall of the filling chamber 21, while maximizing the stirring function of the stirring rod 221.

[0025] Please see Figure 2 and Figure 3 The lifting mechanism 31 includes a lifting cylinder 311 and a telescopic rod 312 disposed above the mounting frame 1 opposite to the filling assembly 2. The stirring mechanism 22 includes a guide rod 222 connected to the telescopic rod 312.

[0026] The guide rod 222 extends into the filling chamber 21 and rotates coaxially with the telescopic rod 312.

[0027] Furthermore, the stirring rod 221 is installed on the guide rod 222 along the length of the guide rod 222 and rotates synchronously with the guide rod 222.

[0028] Please continue reading. Figures 2 to 3 The filling assembly 2 includes a filling rack 25 located below the mounting frame 1.

[0029] Specifically, the filling rack 25 includes an upper fixing plate 251 fixed below the mounting frame 1, a lower mounting plate 252 arranged parallel to the upper fixing plate 251, and a set of support rods 253 connecting the two. One end of the support rod 253 is detachably mounted to the upper fixing plate 251, and the other end is mounted to the lower mounting plate 252 through a threaded engagement with a bolt.

[0030] Furthermore, the filling chamber 21 is formed by a side wall 23 continuously arranged around the outer circumference of the guide rod 222 and a filling port 24 located on the lower wall of the side wall 23. The upper and lower ends of the side wall 23 are connected to the upper fixing plate 251 and the lower mounting plate 252, respectively, and the side wall 23 has a feed port 231 that communicates with the powder feeding pipe. Through the threaded engagement between the lower mounting plate 252 and the support rod 253, a detachable connection between the filling port 24 and the side wall 23 can be achieved, which facilitates subsequent cleaning and maintenance by technicians.

[0031] Furthermore, the filling port 24 is installed on the side of the lower mounting plate 252 away from the side wall 23. The filling port 24 is funnel-shaped, with a discharge port 241 at the end away from the side wall 23. The funnel-shaped filling port 24 facilitates the discharge of powder from the discharge port 241, reduces powder residue on the inner wall of the filling port 24, and accelerates the flow rate of powder in the filling chamber 21.

[0032] Please continue reading. Figure 2The guide rod 222 extends along its own length and is provided with an anti-clogging screw 2221.

[0033] Specifically, the anti-clogging screw 2221 extends into the discharge port 241, and the anti-clogging screw 2221 and the telescopic rod 312 rotate coaxially. In a preferred embodiment, the guide rod 222 is also threaded, which works in conjunction with the stirring rod 221 to further prevent the powder from condensing and causing blockage in the filling chamber 21.

[0034] Please continue reading. Figure 2 The drive assembly 3 also includes a drive motor 32 and a transmission mechanism 33 mounted on the mounting bracket 1.

[0035] The output end of the drive motor 32 extends into the mounting bracket 1 and is connected to the drive gear 321.

[0036] Furthermore, the transmission mechanism 33 includes a driven gear 331 mounted inside the mounting bracket 1 and sleeved on the telescopic rod 312, and a connecting gear 332 that meshes with the drive gear 321 and the driven gear 331 respectively.

[0037] The connecting gear 332 is rotatably mounted within the mounting bracket 1. Preferably, the connecting gear 332 is an idler gear, which has a certain energy storage function, making the entire transmission gear system more stable, thereby ensuring the stable operation of the entire filling equipment and extending its maintenance cycle. Of course, the embodiments of this utility model do not limit the number of teeth of the connecting gear 332, and can be flexibly adjusted according to actual needs to change the rotational speed of the connecting gear 332, thereby meeting the requirements of different filling processes.

[0038] In this embodiment of the invention, the design of the transmission mechanism 33 is optimized through the synergistic effect between the motor and the cylinder, significantly improving filling efficiency. Simultaneously, the connection between the transmission mechanism 33 and the stirring mechanism 22 ensures the efficiency and stability of the filling process, guaranteeing the accuracy of each filling operation.

[0039] Additionally, the mounting bracket 1 includes a mounting base 11 for connecting an external device. In an alternative embodiment, the external device is a robotic arm that can control the movement of the entire filling equipment.

[0040] The implementation principle of the single-head powder filling equipment 1000 in this utility model is as follows: the powder enters the filling chamber 21 from the feed port 231 on the side wall 23. The drive gear 321 on the drive motor 32 drives the connecting gear 332 to rotate, thereby driving the guide rod 222 and the stirring rod 221 on the telescopic rod 312 to rotate. The powder is guided by the rotation of the stirring rod 221 and discharged from the discharge port 241. At the same time, the lifting cylinder 311 drives the telescopic rod 312 to move up and down, driving the guide rod 222 and the stirring rod 221 to move up and down in the filling chamber 21, so as to prevent the powder from condensing in the middle and upper part of the filling chamber 21.
