Weighing Quantitative filling machine can adjust the size of the filling volume by changing the rotational speed of the frequency converter gear, through the filling valve to the filling container dispensing liquid, control the switch on and off of the solenoid valve, drive the implementation of the lever drive to make the conical spool in the filling valve open or close, realize the liquid circuit intermittent opening and closing, showing the whole filling control process. Also can be achieved by controlling the number of running steps of the stepper motor to accurately control the number of revolutions of the gear pump so as to achieve the purpose of accurate measurement.
020-34563445The Filling machine is composed of a barrel feeding mechanism, an online weighing device, a main conveyor belt tracking filling device, a vibrating capping device, a barrel discharging device, etc. The barrel feeding mechanism is composed of a barrel feeding mesh belt, a small barrel distribution screw conveyor belt and a dial, etc. The small conveyor belt adds power to the transportation of the medicine barrels, enabling them to be conveyed smoothly at the required speed. The structure of the online weighing device is independent of the entire transmission mechanism, ensuring a weighing environment. Combined with the load cell, high-precision weighing has been achieved. The oscillation capping device uses a cylindrical CAM mechanism to achieve the tracking function of the filling machine and employs dynamic sealing technology to complete the capping process.
The weighing and quantitative filling machine is a single-head filling machine, which is required to achieve a filling speed of one bucket every three minutes, and its filling volume error is ≤±1%. During the process of filling the liquid medicine with the filling machine, two online weighing devices are used to weigh the same medicine bucket, which is empty and filled with liquid medicine respectively. Each online weighing device is designed with a chuck for taking out and putting back the medicine bucket from the main conveyor belt. There must be sufficient space beside the medicine bucket to be weighed on the main conveyor belt for the chuck to enter and exit to avoid tripping the adjacent medicine bucket. This puts forward requirements for what kind of barrel feeding method to adopt.
