The chamfer 31 is used to prevent the bottles from being centered when the cylinder 204 drives the movable plate 19 to press down. If the bottle is pressed down directly, it will cause damage to the bottle or filling failure. The spring 27 between the positioning block 26 and the mounting block 25 can provide a buffer time for the bottle. The spring 27 is compressed during the downward process to correct the bottle. The rubber block 28 inside the positioning block 26 can not only seal the bottle but also provide some protection. The chamfer 31 can also provide some guidance.

[0027] Baffles 32 are fixedly connected to both ends of the feeding plate 209. The baffles prevent the filled activator from falling out from both sides of the feeding plate 209. An installation strip 33 is fixedly connected to one side of the baffle 32. A waist-shaped groove 34 is opened on the installation strip 33. A connecting rod 35 is opened on one side of the installation strip 33. The connecting rod 35 is fixed to the installation strip 33 by bolts and nuts. A guide block 36 is fixedly connected to the connecting strip. The guide block 36 is triangular and is located above the receiving tank 203.

[0028] The working principle of the utility model is as follows: The feeding component 211 places the bottle to be filled into the receiving tank 203. At this time, the servo motor 201 rotates 30°, and the mounting plate 202 also drives the receiving tank 203 to rotate 30°. The feeding mechanism puts down the next bottle, and the servo motor 201 rotates 30° again. At this time, the first bottle is below the first filling tube 22. The cylinder 1 204 drives the movable plate 19 to press down, and the positioning head 24 on the movable plate 19 positions the bottle. Then, the cylinder 4 21 drives the support plate 202 to press down, and the filling tube 22 enters the bottle for filling. However, the first filling tube 22 is only filled with one-third of the active agent. After filling, the servo motor 201 still drives the mounting plate 202 to rotate 30°. The first bottle brings the second filling tube down, and the second filling tube 22 is still filled with one-third until the third. The first filling tube 22 fills the bottle. When the first bottle is below the first filling tube, the second bottle is at the signal detector 208, and the third bottle is at the feeding assembly 211. When the first bottle arrives at the second filling tube 22, the signal detector 208 detects the second bottle, which is below the first filling tube 22. Therefore, the two filling tubes 22 work simultaneously to fill the two bottles. This process continues until a maximum of three bottles are filled simultaneously. Each time the servo motor 201 stops, the cylinder 212 starts and extends its output shaft into the receiving tank 203. When there is a filled bottle in the receiving tank 203, the output shaft of the cylinder 212 lifts it up, and the bottle falls into the unloading plate 209 under the action of the guide block 36, and is then sent to the next process by the unloading plate 209.
