Solution filling machine is a special equipment to realize automatic metering and filling of liquid products, which is mainly composed of automatic transmission system, weighing system, machine vision addressing system, automatic charging port addressing system, non-drip automatic charging system, filling data query and management system, and only need to place the container in the input end of the transmission system. The rest of the operating procedures (except opening and closing the cover) are automated.
020-34563445According to the design and assembly principles, the solution Filling machine is divided into the liquid suction and filling module, the liquid level tracking module, the automatic control module, and the detection module. The liquid suction and filling module further consists of four modules: the metering module, the liquid suction and filling drive module, the flow distribution module, and the nozzle module.
In the liquid suction and filling module, the metering module adopts a piston metering pump, the drive module uses a servo motor to drive a ball screw, and the distribution module adopts a cone valve type check valve. The liquid level tracking module is achieved by a stepping motor driving a ball screw. The automatic control module adopts the widely used PLC as the control center. The detection module adopts an automatic weighing method. To enhance operability, the human-machine interaction interface enables convenient selection and invocation of filling parameters, and intuitive acquisition of filling results.
The filling equipment fills each packaging bucket. The servo motor rotates to generate driving force, which, under the transmission of the ball screw, drives the piston rod to move up and down. The screw and the piston rod are connected by a slider. To ensure the smoothness of the slider's movement, a linear guide rail is installed on the left side of the slider. Under the drive of the motor, the piston rod of the piston metering pump moves up and down reciprocally. The metering pump is of cylindrical structure, and the movement distance of the piston rod corresponds to the volume of liquid sucked and filled by the metering pump. A check valve is selected as the distribution mechanism. When drawing liquid, the check valve at the liquid inlet opens and the check valve at the liquid outlet closes. During the liquid filling process, the check valve at the liquid outlet opens and the check valve at the liquid inlet closes, thus completing the liquid suction and filling process. The filling nozzle is connected to the distribution structure through a steel wire hose. The filling container is placed on the tray. The liquid level tracking module adopts a stepping motor and a ball screw. The ball screw converts the rotation of the stepping motor into the up and down movement of the tray, thus ensuring a constant distance from the nozzle to the liquid surface of the container and reducing splashing and foaming during the filling process. By changing filling parameters such as filling volume and filling speed on the human-machine interface, the PLC can send corresponding control signals to the servo motor and stepper motor based on the input parameters, thus achieving different filling parameters.
