What is the working principle of an automatic box-sealing machine and an automatic box-folding machine?

　　With the rapid development of the e-commerce industry, automatic box-sealing machines and automatic box-folding machines are becoming increasingly sophisticated in their application on production lines. So, what exactly is their working principle?

　　The automatic box-sealing machine is an automated packaging device that automatically seals the bottom and top of boxes. Its working principle is as follows: After employees or the preceding packaging line place products into the machine, the automatic flap-folding and sealing machine—or a top-and-bottom drive box-sealing machine—automatically seals the cartons. First, operators need to turn on the power and independently adjust the width and height settings. Once these adjustments are complete, they press the start button. After the program starts, the cartons are conveyed along a track driven by belts on both sides. At this point, the carton-flap-folding mechanism on the upper part of the sealing machine is activated, completing the entire sealing process in one step. When the size of the cartons changes, the fully automatic machine automatically repositions itself, folds the top flaps, and transports the cartons appropriately without requiring manual supervision. This machine is ideally suited for integration with fully automated production lines.

　　The automatic box-folding machine and the automatic carton-opening machine share a remarkably similar working principle. First, operators manually place cardboard sheets into the storage hopper of the automatic box-folding machine. Next, after employees turn on the power, the machine starts operating, and the water tank automatically rises to a height where it can be picked up by an electric suction cup. As the motor runs, the box-folding mechanism uses the suction cup to lift the cardboard sheet into position above the grinding tool. Then, a robotic arm presses and punches holes in the cardboard sheet at the precise location of the grinding tool. At this point, the carton is already largely shaped. Finally, the robotic arm securely fastens the side flaps of the carton, and a paper cover locks the cardboard in place—thus forming the carton without the need for tape or hot glue. Lastly, the cardboard is folded into the final carton shape. Once folding is complete, the finished carton is manually placed directly into the packaging box.

　　The above is the working principle and workflow of carton sealing machines and automatic box-folding machines.
