The screw mixer inputs the weight of the ingredients through the host, generates the weight of various materials according to the ratio of raw materials, and transmits it to the PLC through communication. During the dosing process, dynamic real-time monitoring is carried out, other switch quantities sent from each slave are collected regularly, the weight signal of each material is collected in real time and compared with the given signal to determine the next control scheme, and the weight signal is transmitted to the upper computer.
020-34563445The automatic mixer is equipped with an activation hopper and gasification at the bottom of the storage bin. When discharging, the activation hopper vibrates continuously and the gasification purging ensures the smooth falling of materials, and the eccentric vibration module can be used to adjust the vibration amplitude to improve the efficiency and gasification purging frequency. When conveying materials, the conveying capacity and conveying efficiency can be changed by adjusting the air time and material time of the air knife valve, which is helpful to meet some links with high requirements for crushing rate. The pulse interval and pulse width can also be adjusted to avoid dust leakage in the storage bin during transportation.
After the weighing mixer reads it through PLC communication, the corresponding operation is carried out. At the same time, PLC moves the monitoring signals to be collected by the touch screen into the communication storage area, and the touch screen can be monitored on the PC by reading the data, and the whole system is connected in series through pressure elements and Weighing modules, so as to realize industrial automation, improve transportation efficiency and effectively prevent dust leakage, providing good environmental protection for field workers.
The weighing mixer is composed of some pneumatic and mechanical mechanisms, such as positioning mechanism, front silo supporting mechanism and conveying mechanism, etc. The cylinder is equipped with an in-place detection device. The control system consists of operation panel, plc system, weighing module, LCD screen, operation keyboard, process control point and upper computer. The Weighing system ensures the accurate delivery of materials, reads the data of Electronic scales, and displays the data in real time on the special plane display screen. At the same time, the data are sent to the upper computer to form a table for the batch data such as materials and density on the production line and analyze and process it.
In the production of screw mixer, the powder and some media that are not suitable for measurement in pipeline are measured and controlled, taking a typical reaction kettle as an example; Three weighing modules installed at the bottom of the reaction kettle transmit the weight signals of the kettle body to the junction box, which connects the weight signals output by the weighing modules in parallel to the weighing terminal or weighing controller, and the weighing terminal or weighing transmitter processes the weight signals into corresponding weight data. Generally, the weighing terminal can provide certain input and output control functions for the field actuator, while the weighing controller generally provides the weight data and other information to the upper Batching system through a specific form, such as PLC. DCS, etc. Automatic batching system and weighing batching equipment are also suitable for internal mixer, extruder automatic batching equipment, auxiliary machine system on mixer, extruder automatic batching equipment and paddle mixer automatic batching system. The system has the function of automatically weighing and distributing materials such as powder, granule and oil according to the required production formula, and can be adapted to internal mixers, mixers and extruders with different specifications of 75~150L, mainly suitable for the production of large and small material formulas and intelligent storage. Automatic batching equipment for extruder, auxiliary machine system on mixer, automatic batching equipment for extruder, automatic batching system for mixer and automatic batching system for powder are mainly used for automatic batching with formula and secret formula in rubber, feed, food, pharmaceutical and chemical industries. The new error-proof mechanism and weighing and feeding system are adopted in the system, which greatly improves the product quality and batching efficiency of production batching.
