[0023] Example: An automatic weighing and filling machine for pharmaceutical intermediate powders, such as... Figures 1-6 As shown, the system includes a base 1, a discharge port 101, a loader 2, a motor 3, a rotating disk 4, a sealing plate 6, a weighing plate 61, and a torsion spring 17.

The sealing plates 6 close the bottom openings of the pre-drilled slots 5, and the sealing plates 6 are slidably connected to the top surface of the base 1. A torsion spring 17 is sleeved on the rotating shaft of the sealing plate 6. One end of the torsion spring 17 is connected to the base 1, and the other end is connected to the sealing plate 6. A weighing plate 61 is installed on the top surface of the sealing plate 6. A placement platform 10 for placing the powder bottle 102 is connected to the front side of the base 1. A discharge chute 9 is connected to the front end of the base 1. The upper opening of the discharge chute 9 is located at the bottom of the sealing plate 6, and the lower opening of the discharge chute 9 is located at the top of the powder bottle 102. An opening and closing component for controlling the discharge is provided at the bottom of the base 1.

[0024] like Figure 3 and Figure 4As shown, the system also includes an electric push rod 7, a baffle 8, a discharge chute 9, and a placement platform 10. A placement platform 10 for placing powder bottles 102 is connected to the front side of the base 1. The discharge chute 9 is connected to the front end of the base 1. The upper opening of the discharge chute 9 is located at the bottom of the sealing plate 6, and the lower opening of the discharge chute 9 is located at the top of the powder bottles 102. An opening and closing assembly for controlling the discharge is provided at the bottom of the base 1. This assembly includes an electric push rod 7 and a baffle 8. The electric push rod 7 is installed at the bottom of the base 1, and the piston rod end of the electric push rod 7 is connected to the baffle 8. The baffle 8 is press-fitted with the sealing plate 6, and the baffle 8 is slidably connected to the upper part of the discharge chute 9.

[0025] like Figure 2 and Figure 6 As shown, the system also includes a mounting bracket 11, a push rod 12, and a spring 13. The mounting bracket 11 is connected to the top of the front end of the base 1. The push rod 12 is slidably connected to the mounting bracket 11. The lower end of the push rod 12 is slidably connected to the pre-groove 5 of the rotating disk 4. A spring 13 is fitted on the push rod 12. One end of the spring 13 is connected to the push rod 12, and the other end is connected to the mounting bracket 11. The function of the spring 13 is to provide the necessary elastic rebound to ensure that the push rod 12 can return to its original position after operation.

[0026] like Figure 2 As shown, it also includes a dust cover 14. The dust cover 14 is connected to the discharge port of the filling machine 2. The dust cover 14 covers the top of the pre-filled trough 5 to prevent dust from leaking out.

[0027] like Figure 1 As shown, it also includes a protective cover 15. The base 1 is connected to the top of the protective cover 15, the discharge port of the filling machine 2 is located inside the protective cover 15, and the push rod 12 is slidably connected to the protective cover 15.

[0028] like Figure 2 As shown, it also includes a positioning ring 16. The positioning ring 16 is provided on the placement platform 10. The positioning ring 16 is located directly below the lower port of the discharge chute 9. The positioning ring 16 ensures that the powder bottle 102 can be accurately aligned to the correct position each time it is replaced.

[0029] When the filling machine 2 starts working, the pharmaceutical intermediate powder inside the filling machine 2 begins to flow out gradually through the discharge port. First, the motor 3 drives the rotating disk 4 to rotate, and the pre-loaded trough 5 on the rotating disk 4 moves to the discharge port position along a predetermined trajectory as it rotates. Each time the rotating disk 4 rotates 60 degrees, the pharmaceutical intermediate powder in the pre-loaded trough 5 falls onto the weighing plate 61 and begins to be weighed. The weighing plate 61 monitors the weight of the pharmaceutical intermediate powder in real time until it reaches the preset target weight, at which point the filling machine 2 stops discharging. Then, the rotating disk 4 continues to rotate, and a new pre-loaded trough 5 is brought to the discharge port position. The sealing plate 6 always keeps the bottom opening of the pre-loaded trough 5 closed to prevent the pharmaceutical intermediate powder from leaking out.

[0030] When the first container 5 containing pharmaceutical intermediate powder moves to the top of the discharge trough 9, the rotating disk 4 stops rotating, the sealing plate 6 is held in place by the baffle 8, the electric push rod 7 starts to move, pulling the baffle 8 backward, the torsion spring 17 drives the sealing plate 6 to rotate, the opening of the sealing plate 6 aligns with the discharge port 101, the pharmaceutical intermediate powder falls into the discharge trough 9 through the discharge port 101, and slides down the discharge trough 9 into the powder bottle 102, completing one powder filling process. After the powder bottle 102 is filled, the electric push rod 7 pushes the baffle 8 forward, the baffle 8 pushes the sealing plate 6 to rotate again, the sealing plate 6 and the bottom opening of the container 5 are resealed, finally, the rotating disk 4 continues to rotate, and the new container 5 begins to prepare for powder filling, the whole filling process is repeated continuously.

[0031] During each filling process of pharmaceutical intermediate powder, the operator needs to manually operate the push rod 12. Pressing down the push rod 12 causes the bottom of the push rod 12 to slide within the pre-filled groove 5, pushing the pharmaceutical intermediate powder downwards to ensure that the pharmaceutical intermediate powder flows smoothly into the discharge groove 9 and finally falls into the powder bottle 102. At the same time, the spring 13 is compressed, storing a certain amount of elastic potential energy. After releasing the push rod 12, the spring 13 will use the accumulated elastic potential energy to cause the push rod 12 to rebound quickly, pushing the push rod 12 to slide on the mounting bracket 11.

[0032] Throughout the entire pharmaceutical intermediate powder filling process, the dust cover 14 and protective cover 15 provide protection. The dust cover 14 is connected to the discharge port of the filling machine 2 and covers the top of the feed trough 5, effectively preventing the pharmaceutical intermediate powder from escaping, ensuring accuracy while reducing waste. The protective cover 15 is located on top of the filling machine 2. Its function is to prevent external substances from entering its interior, contaminating the pharmaceutical intermediate powder, or affecting weighing. Furthermore, the combination of the positioning ring 16 and the placement platform 10 ensures precise alignment of the powder bottle 102, allowing the pharmaceutical intermediate powder to directly and accurately enter the powder bottle 102, avoiding waste. Each time the powder bottle 102 is replaced, the positioning ring 16 effectively guides the powder bottle 102 to be correctly placed in the designated position, ensuring the smooth progress of each filling process.
