The central conveying system of the injection molding machine mainly includes the processes of feeding, drying, mixing and conveying of plastic particles. In order to realize the automatic control of the conveying system, the following methods can be adopted:
PLC controller:
PLC controller is a kind of programmable logic controller, which can control the operating status and parameter setting of each link through programming. Using the PLC controller, the automatic control of the feeding system can be realized, including the start and stop control of the feeder, the setting of the temperature and drying time of the dryer, the control of the stirring speed and time of the mixer, and the speed adjustment of the conveyor, etc.
Sensors:
Various sensors are installed in the central conveying system to realize the detection and monitoring of materials. For example, a load cell can be used to detect the weight of the material to control the feeding amount of the feeder; a temperature sensor can be used to detect the temperature of the dryer to automatically adjust the drying time; a pressure sensor can be used to monitor the pressure of the conveyor to adjust the conveying speed, etc.
Visual interface:
By installing a visual interface on the injection molding machine, the monitoring and operation of the feeding system can be realized. Through the visual interface, the operator can check the supply of materials and the operating status of the equipment in real time, and can set various parameters, such as feeding amount, drying time, stirring speed, etc. At the same time, the visual interface can also provide various alarm information, such as excessive temperature, abnormal pressure, etc., as well as fault diagnosis and processing functions.
Data transmission and Internet application:
The feeding system of the injection molding machine can also perform data transmission and Internet application with other equipment. Through network connection, remote monitoring and operation of the feeding system can be realized. For example, the operating status of the feeding system and the supply of materials can be viewed remotely through the mobile app, various parameters can be adjusted remotely, and remote fault diagnosis and processing can be realized.
Automatic feedback control:
In order to realize the automatic control of the feeding system, an automatic feedback control method can also be used. By collecting data from various sensors, such as material weight, temperature, pressure, etc., and then controlling each actuator according to the preset control strategy and algorithm. For example, when the temperature of the dryer is too high, the drying time can be automatically adjusted to keep the temperature within an appropriate range.
How to realize automatic control of injection molding machine central conveying system?
To sum up, the feeding system of the injection molding machine can be automatically controlled through technical means such as PLC controllers, sensors, visual interfaces, data transmission, central feeding systems, and automatic feedback control. The application of these technologies can improve the operating efficiency and stability of the feeding system, reduce human error, and improve the production efficiency of the injection molding machine. At the same time, through remote monitoring and fault diagnosis, the fault of the feeding system can be dealt with in time to increase the stability and reliability of the production line.
