The Activation 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 activated screw mixer is equipped with an activated hopper and a vaporizer at the bottom of the storage bin. During the discharge process, the continuous vibration of the activated hopper and the purging of the vaporizer ensure smooth material descent. Moreover, the eccentric oscillation module can be used to adjust the vibration amplitude to enhance efficiency and the frequency of vaporization purging. When conveying materials, the conveying volume and 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 the crushing rate. The pulse interval and pulse width can also be adjusted to prevent dust leakage from the receiving bin during the conveying process.
After the weighing mixer reads the data through PLC communication, it then executes the corresponding operation. Meanwhile, the PLC moves the monitoring signals to be collected by the touch screen into the communication storage area. By reading the data in it, the touch screen can monitor it on the PC. The entire system is connected in series through pressure elements, Weighing modules, etc., to achieve industrial automation. This not only improves the conveying efficiency but also effectively prevents dust leakage. It provides good environmental protection for on-site workers.
The weighing mixer is composed of some pneumatic mechanical mechanisms such as positioning mechanisms, front support bin mechanisms and conveying mechanisms, etc. A position detection device is installed on the cylinder. The control system is composed of an operation panel, a plc system, a weighing module, a liquid crystal display screen, an operation keyboard, process control points and an upper computer, etc. The Weighing system ensures the accurate and precise delivery of materials. The data from the Electronic scale is read and displayed in real time on the dedicated machine's display screen. At the same time, the data is sent to the upper computer to form tables for batch data such as materials and density on the production line, and to conduct analysis and processing.
In the production of screw mixers, powder materials and some media that are not suitable for measurement in pipelines are measured and controlled. Taking the weighing of a typical reaction vessel as an example; Three weighing modules installed at the bottom of the reaction vessel transmit the weight signal of the vessel body to the junction box. The junction box connects the weight signals output by the weighing modules in parallel to the weighing terminal or weighing controller. The weighing terminal or weight transmitter processes the weight signals into corresponding weight data. The weighing terminal usually provides certain input and output control functions for the on-site actuator, while the weighing controller generally provides weight data and other information to the upper-level Batching system in a specific form, such as PLC, DCS, etc. The automatic batching system, which is used for weighing and batching equipment, is also applicable to the automatic batching equipment of internal mixers, extruders, auxiliary systems of mixers, automatic batching equipment of extruders, and automatic batching systems of paddle mixers. This system has the function of automatically weighing and delivering powder, granular, oil and other materials according to the required production formula. It is compatible with different specifications of internal mixers, mixers, extruders, etc. ranging from 75 to 150L. It is mainly applicable to the production of large and small material formulas. It can intelligently store production formulas, call up production formulas at any time, and store production data, which is conducive to product quality traceability. The automatic batching equipment for extruders, auxiliary systems for mixers, automatic batching systems for extruders, automatic batching systems for mixers, and automatic powder batching systems are mainly used in the rubber, feed, food, pharmaceutical, and chemical industries for automatic batching and formula confidentiality and other process links. The system has adopted a brand-new error-proofing mechanism and weighing feeding system, which has greatly improved the product quality and batching efficiency of production batching and other aspects.
