Oral liquid filling machine

Automatic liquid filling line is a widely used automated production equipment in the pharmaceutical, health care and food industries, mainly used for quantitative filling and sealing of liquid products. In this article, the working principle of oral liquid high-speed filling machine will be introduced in detail, mainly covering the transmission and synchronisation mechanism, liquid supply and flow rate control, container conveying and positioning, filling needle tracking and filling, defoaming and accurate filling, cap arrangement and delivery, cap pressing and sealing, as well as automation control and operation.   First, transmission and synchronisation mechanism   Oral liquid filling line transmission and synchronisation mechanism is the key to ensure stable operation of the equipment. Usually, the equipment is driven by servo motors or stepper motors, and through precise transmission devices, such as gears, chains or synchronous belts, etc., to achieve the coordinated work of various components. In addition, the use of encoders, sensors and other feedback devices to ensure precise control of the movement speed and position of the equipment to achieve high-speed and efficient production.   Second, the liquid supply and flow rate control   The Oral liquid filling machine supply system is responsible for transporting liquid raw materials to the filling head. Through liquid pumps or peristaltic pumps and other devices to achieve stable delivery of liquid. Flow rate control depends on precise flow regulation devices, such as flow meters or proportional valves, to ensure stable and accurate liquid flow rate.   Third, the container delivery and positioning   Container conveying system is responsible for transferring empty bottles to the filling station. This is usually achieved by means of conveyor belts, chutes or rotating discs. In order to ensure the accurate positioning of bottles, the equipment is equipped with positioning devices, such as cylinders, motors, etc. Through precise control, the precise positioning of bottles in the filling station is achieved.   Fourth, the filling needle tracking and filling   Filling needle is the key component for liquid filling. After the bottle is positioned, the filling needle automatically descends and inserts into the bottle mouth for filling. In order to ensure the accurate docking between the filling needle and the bottle mouth, the equipment adopts tracking devices, such as photoelectric sensors or visual recognition systems, to monitor the position of the bottle mouth in real time and adjust the position and height of the filling needle. During the filling process, precise quantitative filling is achieved by controlling the opening and closing time of the filling needle and the flow rate of the liquid.   V. Anti-foaming and precise filling   In order to avoid air bubbles in the filling process, affecting the filling accuracy, oral liquid high-speed filling machine is usually equipped with anti-foaming devices. These devices eliminate air bubbles in the liquid through blowing, pumping or mechanical vibration to ensure the accuracy of filling. At the same time, through the precise metering system and flow rate control, the precise filling of each bottle is achieved to meet the product quality requirements.   Sixth, cap arrangement and conveying   Cap arranging and conveying system is responsible for orderly conveying the caps to the sealing station. The bottle cap first passes through the arranging device, so that it is neatly arranged on the conveyor belt. Then, the bottle caps are transported to the corresponding bottles on the conveyor belt, ready for sealing.   Seventh, bottle cap pressing and sealing   After the cap is conveyed in place, the Oral liquid bottling line will press the cap on the bottle mouth through the pressing mechanism. The pressing mechanism usually adopts cylinder or electric actuator and other devices, through precise control of the pressing force, to ensure that the cap and the bottle mouth of the close combination. At the same time, the sealing device such as rotary cap head or compression cap head, the bottle cap sealing operation to ensure that the bottle is sealed.   Eight, automatic control and operation   fully automatic 4/6/8/10/12 filling heads Oral Liquid Filling Machine for Pharmaceutical Industry Plant adopts advanced automation control system to achieve precise control of the whole production process. The control system is usually composed of PLC (programmable logic controller) or microcontroller and other core components, through the programming to achieve the equipment's motion control, logic judgement and data processing and other functions. Through the touch screen or computer interface, the operator can conveniently set the parameters of the equipment, monitor the operating status and view the production data. In addition, the equipment also has fault self-diagnosis and alarm function, can be timely found and deal with equipment failure, to protect the smooth progress of production.   In summary, the Pharmaceutic Oral Liquid Filling Machine achieves efficient and accurate oral liquid filling production through the transmission and synchronisation mechanism, liquid supply and flow rate control, container conveying and positioning, filling needle tracking and filling, defoaming and accurate filling, cap arrangement and conveying, cap pressing and sealing, as well as automation control and operation, and other aspects of the collaborative work. The in-depth understanding and application of these technical principles help to improve the production efficiency and product quality of the equipment and create greater economic benefits for the enterprise.
