The double head edge sewing machine for cement bag mainly includes feeding conveyor belt, tooth guard, main conveyor belt, industrial sewing machine, paper feeder, air shear and other parts. The feeding conveyor belt, main conveyor belt and industrial sewing machine are driven by frequency converter, and their linear speed is required to be the same during operation. The feeding conveyor belt has been running since the start-up, and the woven bags are manually put on the feeding conveyor belt by workers. When the distance between the main conveyor belt and the main conveyor belt is set, when the distance between the main conveyor belt and the main conveyor belt is set. Only in this way can we ensure the production and operation with high efficiency.
Advantages of system scheme
1. Running the frequency converter in the way given by the external terminal can accurately control the running time of the main conveyor belt frequency converter. If the frequency converter is operated in the way of communication, there may be interference in the Modbus communication, thus affecting the spacing of the sub bags.
2. The main engine inverter has large starting torque and strong overload capacity, and can operate for a long time under 110% overload. At the same time, the production speed and efficiency are improved.
Frequency converter, fast acceleration and deceleration time, 3.
4. The inverter has high speed stability accuracy, and the whole line speed is required to be the same during operation. If the speed stability accuracy is low, it is easy to cause the sewing machine needle to be broken.
5. Low failure efficiency and convenient maintenance.
