The working principle of the strapping machine is relatively simple and efficient. It mainly consists of a carrier, a load module, a tensioning device, and a binding device. When working, first place the items that need to be tied on the load module and ensure their stability by adjusting the fixtures or molds. Then, use a tensioning device to tighten the rope or string, and finally use a tying device to tie the rope or string around the item, completing the tying process.
