The epoxy resin filling machine utilizes the weighing module to connect with the weighing instrument with data line, and control the instrument to stop the pump and close the pneumatic valve when the preset quantitative weight is reached. The weighing and filling machine is controlled by PLC programmable device, when the container is fed in, the scale motorized drum runs at the same time, the photoelectric switch on the weighing module detects the signal sent by the container passing by, and controls the motor to stop the container and sends out a signal when the container reaches the filling position, and the PLC controls the motorized rollers to stop and tare the container automatically, and the filling valve is driven by the stepping motor to drop down and reach the lower limit, and the well is sent out by the travel switch, and PLC controls the filling valve to be fully opened for filling. The valve is fully opened for filling.

Diluent filling machine corresponds to the filling valve fast open valve filling, open the slow solenoid valve, PLC according to the running position of the encoder to determine the opening and closing state of the filling valve, bus transmission to the controller for opening and closing the filling valve, and through the RS485 to the controller for parameter setting, recipe selection, residue recovery and so on. After the filling is finished, a material recovery button is set in the filling and weighing screen to recycle the remaining residual material around the drop filling valve body, after selecting this button, the recycling tank cylinder moves and the residual material enters into the recycling drum through the pipeline.

Gasoline filling machine is mainly composed of weighing platform, support column, ball screw, filling pipe, filling gun, pot pressure, moving filter, ventilation device, electrical control box, stepping motor and so on. The weighing instrument support column supports the entire filling mechanism, including the frame of the ball screw, stepper motor, filling pipe, etc. The stepping motor drives the ball screw to drive the filling pipe and the filling gun up and down, and the material is pressed into the packaging drum through the movable filter, the filling pipe and the filling gun.

Weighing filling machine is a weighing filling, filling control, discharge and other computerized production process control and data management as one of the integrated automated filling control system, liquid filling machine using Mitsubishi Q series PLC and Advantech industrial control microcomputer to set up a high-performance control platform.

Weighing filler consists of feeding pump, solenoid valve, pipeline and weighing system. When the liquid level of the reaction tank is lower than a certain position, the solenoid valve opens, and the liquid flows into the dosing tank through the feeding pump and pipeline, and the solenoid valve closes when the liquid reaches the liquid level height.

The automatic filling machine can observe the weighing data through the meter head, in addition the profibus-DP bus transmits the weighing data to the PLC, which reduces the errors caused by interfering signals, transmission or conversion, and ensures the filling accuracy in production. Communicate with PLC through MPI interface, give all kinds of control parameters, control instructions, control the action of PLC; read the status information of PLC for the screen real-time dynamic display of the process of equipment status, weighing data, alarm information. The computer also has the functions of system security setting, filling management, production report inquiry and printing, scale zero calibration and scale parameter setting.

The liquid filling machine will send the empty barrel to the filling position and align the barrel mouth with the spray gun mouth. When the detection spray gun is in place, the bottom valve will be opened and the nitrogen filling valve will start to fill the dry nitrogen into the barrel through the filling mouth, so that the air in the barrel will be replaced by nitrogen, and the drying of the inner wall of the barrel can be accelerated to ensure the safety of filling. When filling with nitrogen, it should be ensured that the air in the container is completely replaced, and the specific amount of nitrogen can be adjusted by the controller time.

The weighing and filling machine is mainly composed of four main parts: transfer device, filling device, suction and sealing device and detection electronic scale device. Integrate informationization accessory equipment, such as printers, scanning guns, RFID and other information identification equipment, to give the material into the weighing and dispensing process of identifiable information. Adopt CS control management server as the server to manage the whole filling. The industrial Ethernet is used as a network to connect the operating stations of each process. An operator station is placed at each process and connected to each process equipment. Functions of each station are realized by the operator station.

The automatic filling machine adopts Siemens S7300 series and ET200 module to control the filling according to a certain ratio, and at the same time, it gives the discharging system according to the information of the material level of each material reaction tank. According to the weight and chemical composition of the raw materials for proportion filling control. Adopting two-stage adjustable filling methods for large and small materials, the filling machine improves the accuracy and production capacity; equipped with top barrel automatic protection function for automatic lifting of the filling gun when the gun is not inserted into the barrel and not performing filling; the filling gun is professionally designed for ink, and it is easy to dismantle and install it quickly with bare hands and convenient for maintenance.
