An electronic scale is installed between the lifting base and the support of the injection molding platform. The gear pump control circuit and the electronic scale are all connected to the frequency converter and PLC. The injection gun is driven to perform automatic material dispensing by the cylinder. After weighing, the material is sent to one end of the empty barrel. The weighing system first weighs and then dispenses the material. The weight of the material is converted into pulse equivalent to achieve slow dispensing by pulses. Through dynamic measurement by the electronic scale, the measurement error signal is fed back to the PLC system, and the driving pulse of the dispensing stepper motor can be randomly adjusted to achieve very accurate filling measurement requirements.
020-34563445The injection scale can vary for different types of liquids, thick liquids or sauces, and is suitable for non-corrosive thick liquids. It uses a high-precision stainless steel rotor pump to measure the liquid volume. Each pump is driven by a servo motor, and the filling volume can be directly adjusted on the touch screen. The lifting of the valves is driven by the servo motor, and the top-down Filling system can be used for the filling of foamy liquids. The scale consists of the filling gun cylinder, the scale weighing platform, the scale frame, the Electronic scale, and the actuating cylinder. The Weighing system converts the weight of the material into electrical energy through an electronic scale, then converts it into digital quantity through an A/D converter, and feeds back the measurement error signal to the PLC system. By randomly adjusting the driving pulse number of the feeding stepping motor, very accurate filling measurement requirements can be achieved. The electronic scale always tracks, queries, and processes the weighing platform. The filling gun actuating cylinder works under the action of the driving pulse. When the weight reaches the required weight, filling is carried out.
The structure of the Filling machine's scale includes a lifting base, a support, a gear pump, a filling gun, a conveying mechanism and a control mechanism. It adopts a dual-speed filling gun. The filling gun is simultaneously connected to the large piston, the small piston or the three-phase. The outlet of the dual-speed filling gun is set on the upper side of the conveying mechanism. An intermediate oil storage tank is set between the filling gun and the pipeline. Both the filling gun and the intermediate oil storage tank are fixed on the support. An electronic scale is set between the lifting base and the support. The gear pump control circuit and the electronic scale are connected to the PLC through a frequency converter. The filling gun is driven to perform automatic dropping of the cylinder, and the weighed material is sent into an empty barrel at one end. The weighing system first weighs and then drops the material, converting the material weight into pulse equivalents to achieve slow pulsating dropping. The measurement error signal is dynamically measured by the electronic scale and fed back to the PLC system. By randomly adjusting the driving pulse of the dropping stepper motor, very accurate filling measurement requirements can be achieved.
