Automatic Speed Regulation System of Pillow Packing Machine Based on Double Sensors
The speed regulation system of packaging machine has some problems such as long time to enter steady state,steady state er-ror is large and regulation precision is low,which lead to high damage rate of products.An automatic speed regulation system of pillow packing machine based on double sensors is proposed.The system hardware adopts temperature sensor and position sensor,and the speed of each mechanism is converted and adjusted by PLC,automatic adjustment of packaging machine speed is realized.When the packaging box is transferred to the end sealing position and temperature,the system software adopts the principle of equal time to deter-mine the time to match the speed,the speed change is determined according to the gear transmission principle,and the automatic speed adjustment of the pillow packaging machine is realized.The experimental results show that the time of the design system to enter the steady state is only 20 s,and the packaging damage rate is lower than 7.5%.The overshoot of the system is reduced,the time is short-ened,the control accuracy is improved,and the packaging damage rate of products of different sizes is reduced.The proposed system has good versatility and reliability.
