[0044] Before the work starts, the packaging bottle is placed under the weighing assembly 4 in the designated area, and the control system initializes the target weight value. When the start button is pressed, the control system first records the initial weight of the packaging bottle, and then instructs the filling nozzle 22 to descend to the lowest point and contact the packaging bottle. As the liquid flows in, the weighing sensor 41 continuously monitors the change in the total weight of the weighing tank 42, and once the preset value is reached, the oil pump 211 immediately stops the liquid supply and directs the filling nozzle 22 to quickly lift up to prevent excess liquid from overflowing. The entire process is highly automated, significantly reducing the possibility of human intervention and greatly improving production efficiency.

[0045] The implementation principle of the follow-up type upper weighing filling machine according to an embodiment of the present application is as follows: the oil pump 211 draws liquid from the weighing tank 42, the weighing sensor 41 weighs the mass of the liquid in the weighing tank 42, the lifting mechanism 13 lifts the filling assembly 2 to the designated position, the conveying belt 11 conveys the packaging bottles, the horizontal movement servo motor 231 drives the gear 236 to rotate along the rack 235, realizing the horizontal movement of the filling nozzle 22, the lifting cylinder 243 and the cross plate 242 cooperate to make the filling nozzle 22 vertically ascend and descend, the arc block 33 positions the packaging bottle, and the filling assembly 2 works to generate vibration. Since the flexible connection between the soft connecting pipe 43 and the weighing tank 42 is flexible, the vibration will not affect the weighing assembly 4, and the weighing assembly 4 is used to weigh the weighing tank 42, so the temperature change will not affect the weighing result. The soft connecting pipe 43 is conducive to reducing the influence of the vibration generated by the filling assembly 2 during work on the weighing assembly 4, so that the weighing assembly 4 can remain stable in the face of large environmental changes, and the filling nozzle 22 can still accurately fill the packaging bottle when following the movement of the packaging bottle, improving the filling efficiency and filling accuracy.
