Intelligent Touch Control for Precision Mixing: Analysis on HMI Control System of Mill Machinery Laboratory Internal Mixer
In the research and development as well as formula debugging of polymer materials, rubber and composite materials, laboratory internal mixers act as core equipment for mixing processes and direct sources of experimental data. The intelligence level, data acquisition capability and maintenance convenience of the control system directly affect experimental accuracy, traceability and operation & maintenance efficiency. Our laboratory internal mixers are equipped with a color human-machine interface (HMI) control system. Featuring full-process digital management, multi-dimensional data collection, one-click formula management and intelligent fault diagnosis, it creates an efficient, transparent and traceable mixing experiment platform for researchers.
1. Programmable Color HMI: Visualized Full-process Operation
Real-time data display: It clearly presents key indicators including running time, temperature, current and torque. Users can directly compare set values and actual values to check operating status.
Integrated control area: All functions such as start/stop, ram lifting & lowering and chamber opening & closing are available via touch buttons. It supports manual single-step commissioning and automatic operation with preset programs.
Process timing module: The built-in timer records the whole mixing duration accurately, facilitating unified management of multiple batches of experiments.
The system supports programming and editing of formula processes. Mature mixing parameters can be saved under custom codes for one-click recall in subsequent tests. Operators can also modify or delete stored formulas flexibly, effectively avoiding parameter errors caused by manual entry and guaranteeing consistent experimental results across batches.
2. Full-dimensional Data Recording, Export and Storage
Equipped with a standard USB interface, the device supports one-click data export. The exported data will be automatically generated into standard Excel files, which can be directly used for sorting, analysis and report compilation. In addition, the system supports offline data storage and on-site printing, enabling complete data archiving and full lifecycle traceability of every experiment. Researchers can compare data of different formulas and processes conveniently to accelerate formula optimization.
