Liquid Bottling Machine

The liquid bottling machine line operates based on a logic of dynamic tracking: bottles are continuously fed into the work area via a conveyor system. Position-sensing components constantly capture signals from the bottles, triggering the filling-tracking mechanism to initiate synchronized movement. The filling head moves in tandem with the bottle to deliver a precise, metered dose of liquid; once the filling is complete, the module rapidly resets to await the next bottle.
After filling, the bottles are smoothly transported to the capping station. A dedicated cap-handling unit manages the sorting, orientation, and pre-placement of the caps. A servo-driven capping module then engages, tracking the bottle's movement to secure the cap to a specified torque. Once the cap is tightened, the capping mechanism disengages and returns to its home position.
The system incorporates integrated protective logic that automatically synchronizes the operating speeds of the filling and capping units, preventing bottlenecks or jams that could otherwise arise from a mismatch in throughput. The production line supports both standalone commissioning and integrated production modes; individual units-filling or capping-can be operated separately during the debugging phase, making it easier to identify and troubleshoot issues.

Once the equipment is started, empty bottles enter the filling zone via a conveyor belt. Photoelectric sensors detect the position of each bottle and relay this information to the PLC control system. A servo-driven mechanism synchronizes the movement of the filling heads with the speed of the bottles; as they move in tandem, the metering system dispenses a preset volume of liquid into each bottle, automatically ceasing flow once the target quantity is reached. The bottles then continue along the conveyor to the capping zone, where an automatic cap-sorting and feeding mechanism delivers caps to the designated position. A servo-controlled capping head moves in synchronization with the bottle to perform cap positioning, downward pressing, and tightening. Throughout the process, the control system coordinates the operational timing across all stations, enabling precise liquid filling, automatic capping, and the continuous output of finished products.

The tip of the filling nozzle can be equipped with an anti-drip component tailored to the characteristics of the liquid, preventing residual liquid from continuing to drip after the flow has stopped.

The servo motor provides power to the tracking mechanism, executing actions such as acceleration, constant-speed movement, deceleration, and returning to the starting position, in accordance with commands from the control system.

The liquid bottling machine lateral restraint assembly for the conveyor belt is used to constrain the lateral position of bottles within the capping area, preventing them from shifting significantly during transport.

Adjustable leveling feet are provided at the base of the rack to allow for horizontal alignment during equipment installation. Adjusting the height of these feet helps improve the stability of the equipment when installed on various types of factory flooring.
