Machine Control System:

1. The main function of the control system is to ensure that the injection machine works accurately according to the predetermined requirements (pressure, speed, temperature, time) and sequence of the process.
2. In the rubber injection machine, the competition in the industrialized countries is mainly reflected in the competition of the control system and the degree of turbulence, so that the control system and automation of the equipment are rapidly developed. At the beginning of the development of the injection machine, the control of its movement, such as the stroke of the screw and the stroke of the injection machine, mainly use the stroke switch or the proximity switch to realize the action of the actuator, thereby controlling the movement or stopping in the corresponding component; the detection of its parameters, such as : Pressure gauges and thermometers are used for parameters such as pressure and temperature. With the advent and development of programmable logic controllers (PLCs), rubber injection machines have also rapidly applied programmable controllers, which use pulse quantities or amounts of time to control the process, making control levels a big step forward. In recent years, programmable controllers have been greatly developed and given the functions of microcomputers, such as statistical engineering control (SPC) for execution online, computer integrated management production control (CIM), hierarchical data collection and processing control (MIR). ) and information control management system (MCS2) and so on. These controllers have the advantages of strong data acquisition, strong data processing capability (such as calculation, transformation, search, comparison, etc.), large storage capacity, fast calculation speed, high precision and strong communication ability, which make the control of rubber injection machine. The level has made breakthrough progress.
3. Industrialized countries have equipped various microprocessor controllers and software packages in the injection machine control system. It can easily detect and control the vulcanization time, vulcanization temperature and vulcanization pressure of each injection machine. At the same time, the control system is matched with the equipment, and the central computer inputs the data, and then the integrated production management information is further processed and SPC evaluation. Most injection machine network systems have "grading data collection and processing" functions, which can be divided into real-time process detection, process control, injection machine monitoring, and management control. If the injection machine has an associated controller, the injector's variables can be monitored regularly and the injection procedure can only be sent to the injection machine; alarms can be set up, as well as warnings of faults or critical parameter deviations; Self-diagnosis, raw material planning, selection of Zuijia use conditions and recording of production data and other functions. At present, the control system and automation level of the rubber injection machine can be automated using robots and the whole process.
