[0002] Most of the existing packaging methods for stacks with large volumes or mechanical equipment use prefabricated packaging film bags for wrapping, and a few use winding manipulators for wrapping the packaging tape; the advantages of prefabricated packaging bags are obvious, that is, good sealing and fast wrapping, and the packaging process is short. The current prefabricated packaging bag packaging machinery and equipment generally have four manipulators at the four corners of the receiving position. After the negative pressure absorption port at the end of each manipulator sucks one corner of the bag mouth tightly, the four manipulators are opened under the drive of the unfolding mechanism to pull the packaging bag to the packageable size, and then the four manipulators move to the top of the stack to be packaged, and transfer the bag mouth position of the opened bag body to the bagging mechanism, or use the manipulator to directly wrap the stack. However, since most of the packaging sites are factory spaces, they are generally relatively open or have a large wind flow speed for cooling. The method of using negative pressure to absorb the bag film body often causes dislocation or even falling off, resulting in frequent machine alarms and poor grasping efficiency. The manufacturing cost of the equipment using manipulators for displacement is high, and the probability of failure is also high. Summary of the invention
