working principle
1. The automatic weighing and packaging machine receives analog signals of weight through pressure gauges and sensors, converts them into digital signals, and controls the contactor and shaft solenoid through relay switching signals to achieve engine shutdown and cylinder operation. The unloading principle is to use the high-speed rotation of the power head blades to quickly remove the material from the unloading hole, and the internal air is blown into the power head to generate high pressure and discharge the material, helping the blades disperse the material.
2. Fill the material according to the specified weight, transport it to the sewing machine through a belt conveyor, and seal it.
3. Sewing machine: fully automatic sewing machine, fully automatic tangential multifunctional sewing machine.
4. Related equipment: automatic folding machine. If the bag needs to be folded, you can choose a folding machine and then close it with a sewing machine.
