The ink filling machine uses the weighing module to connect with the data line of the weighing instrument, and controls the instrument to stop the pump and close the pneumatic valve when the preset quantitative weight is reached. Controlled by a PLC programmable device, the electric drum of the scale body runs simultaneously when the container is sent in, the photoelectric switch on the weighing module detects the signal sent by the passing container, controls the signal sent by the motor when the container reaches the filling position, and the electric rolling is stopped by the PLC and the skin is automatically peeled, the filling valve is driven by the stepping motor to reach the lower limit, and the well is sent by the travel switch. PLC control filling valve is fully opened for filling.
020-34563445The liquid ink Filling machine is controlled by PLC as the core, which controls the opening and closing of the feeding valves and the start and stop of the conveyor belt. The weight signal source is collected by the Electronic scale. The Filling system consists of two parts: manual and automatic control systems. The manual control system exists as an emergency control, while the automatic control system uses PLC to achieve. The weight signal sent by the electronic scale is converted by the A/D conversion module and then processed by PLC, and then calculated by the internal program of PLC. The current weight, peel weight, actual weight, net weight, output, etc. are displayed on the touch screen. The touch screen can set automatic peeling or manual peeling as well as the weight of each filling liquid. When the system is in automatic mode, the conveyor belt starts running. When a filling bucket passes through the filling part, the conveyor belt stops running. The drive part of the conveyor belt can be controlled by frequency conversion, which can control the speed of the conveyor belt and reach the designated filling area. The electronic scale weighs the filling bucket and automatically peels it, and then fills the bucket (there are two filling methods: fast and slow). When it is about to fill to the preset weight, it uses the slow filling method to prevent liquid overflow. When the preset filling weight is reached, the filling stops. After the filling is completed, the conveyor belt continues to run and transports the filled liquid to the next process. The touch screen counts each filling and can monitor the output.
The double piston weighing filling machine is composed of a large piston filling gun, a small piston filling gun, a filling mechanism, an electronic scale, a conveyor frame, and a storage bin, etc. After the equipment is started, the conveying mechanism starts running. The filling gun is composed of a rotor pump motor, a reducer, and an axis with an piston cylinder. The piston axis extends up and down, causing the material to have relative motion along the piston surface. The material is pushed axially by the friction force of the material trough or the wall of the conveying pipe, achieving material transportation. When the material is poured, the large and small piston filling guns work simultaneously. The operation of the large piston filling gun can improve the efficiency of material pouring. When the weight of the material reaches a preset value (the preset value is generally set to about 95% of the final weight of the material), the electronic scale sends a signal to the control system, and when the target quantity is reached, the control system stops the step motor of the small piston filling gun, and the material flows freely, the small piston filling gun continues to operate to achieve the purpose of precise feeding.
The automatic filling machine uses the data line of the electronic scale and the weighing instrument to control the pump to stop and close the pneumatic valve when reaching the preset quantitative weight. It is controlled by PLC programmable controller. When the container is fed, the electronic scale's electric roller simultaneously operates. The photoelectric switch on the electronic scale detects the signal from the passing container and controls the motor to stop when the container reaches the filling position. The PLC controls the electric roller to stop and automatically peel, and the filling valve is driven down to the lower limit by the step motor. The travel switch sends a signal, and the PLC controls the filling valve to fully open for filling.
When the liquid is filled through the rotor pump, the speed of the rotation can control the amount of material discharged by the motor, and the motor is adjusted by the speed weighing instrument to regulate the speed of the AC speed-regulating motor. The external automatic control system signal is used to adjust the motor speed, achieving a wide range of stepless speed regulation. The entire weighing process is detected and output by the scale frame and the electronic scale for digital signal output. The signal amplifier amplifies it and sends it in the form of current to the weighing instrument. The weighing instrument performs calculation processing to obtain the current material multi-end flow rate and compares it with the current flow rate value to send a PID control signal to control the feeding equipment to reach the required flow rate. A local area network is used to realize communication between the on-site computer and the filling equipment, and through the RS485 network, it can communicate with the control host. Using multiple modules can conveniently form a distributed control network of RS485.
