Liquid filling machine belongs to the packaging machine. From the Angle of the packing of the material, can be divided into liquid filling machine, paste liquid filling machine, liquid powder filling machine and particle liquid filling machine. Degree of automation can be divided into semi-automatic liquid filling machine and automatic liquid filling machine. Want to know how to choose the liquid filling machine? First of all, let us first understand the working principle of liquid filling machine.
Liquid filling machine is mainly divided into three parts: storage tank, filling the host and frequency control of motor speed transmission module.
Disinfectant liquid filling line filling and packing
Tank located at the top of the equipment, is a liquid level sensor and feed solenoid valve normal pressure tank. Before sending a process of liquid materials through electromagnetic valve into the tank. When reach the appropriate level, liquid level sensor will send signal to close/stop feeding; When the material surface down to the specified location, it will automatically open. Into the solenoid valve. At the bottom of the tank, discharge through the pipe connected to the suction tube filling of the host, when host is working, the liquid in the tank is inhaled the piston in the cylinder, and then through the nozzle bottles.
Liquid filling host
Liquid filling host is complete filling operation of the main equipment. The front of the host is equipped with multiple filling head, set on both sides of the cylinder set, one for each cylinder filling head. The liquid in the tank is into a cylinder, and then crushed out, and by filling in the corresponding bottle. Filling head of the cylinder driving small piston to open and close the filling nozzle of the head, the nozzle used for the valve. At the beginning of filling, insert nozzle into the bottle, and at a certain distance from the bottom of the bottle to open small piston to start filling. Filling head and populate the edge until the filling is complete, then close the nozzle and promoted to the position of the bottle. . On the side of the filling stage, there are two driven by cylinder plug (one at the entrances to the bottle and the other one in the export of bottle), with the bottle in the filling stage of bottle device, for fine filling.
Liquid filling machine transmission module
Conveyor motor controlled by frequency converter, in order to realize the stepless speed change and economic running. Motor starts, imported cylinder retracted, an empty bottle from the conveyor into the bottle to start; Then, export cylinder, and blocked by export plug into the empty bottles. Photoelectric switch is set at the entrance to detect bottle. When the number and the number of filling head at the same time, import cylinder will be stretched out, and imports will be stop stop, and conveyor motor will be stopped. After the completion of the filling, filling head rise, discharging cylinder retracted, conveyor motor to begin to spin again, fill the bottle is sent out.
