[0002] With the development of the back-end packaging industry, the packaging method of wrapping goods with stretch film is becoming more and more widespread. However, for random pallets, the only option is to wrap and pack the goods after arranging them neatly. Despite this, robot loading also faces more problems. If production is to be carried out at a higher speed, there are various ways to stack goods in the logistics industry, and the goods are rarely stacked neatly, which increases the difficulty of wrapping and packing goods. In the existing logistics packaging process, the goods are neatly placed manually, which is time-consuming and labor-intensive, seriously increasing labor costs, and taking up a large space and low production efficiency. Therefore, we proposed a palletizing and wrapping all-in-one machine to solve the above problems. Utility Model Content
