[0018] Beneficial effects:

[0019] 1. A double-headed screw, a slide rail, and a connecting plate are provided. The double-headed screw is driven to rotate by a motor through a transmission wheel and a transmission belt. Since the double-headed screw is threadedly connected to the robotic arm, the robotic arm can move along the axial direction of the double-headed screw. The auxiliary chain is engaged with the rear of the packaging machine to provide additional support and guidance for the robotic arm. During the movement of the robotic arm, the auxiliary chain can limit the movement direction of the robotic arm to prevent it from deflecting or shaking, ensuring that the movement of the robotic arm is more stable and accurate. The slide rail provides a stable track for the movement of the connecting plate. By moving the connecting plate, the position of the auxiliary arm inside the robotic arm can be adjusted to perform operations such as grabbing and carrying packaging boxes, so that it can better adapt to the production requirements of packaging boxes of different sizes and shapes.

[0020] 2. The cylinder and the suction nozzle are provided. The cylinder provides the power source for the movement of the suction nozzle. In the process of grabbing the unformed packaging box, the cylinder can accurately control the extension and contraction movement of the suction nozzle. When the packaging box needs to be grabbed, the cylinder is activated to push the suction nozzle closer to the unformed packaging box. The suction nozzle generates adsorption force through negative pressure to achieve the grabbing of the unformed packaging box. When the suction nozzle contacts the packaging box, a negative pressure environment is formed inside, which firmly adsorbs the packaging box and transports it to the designated location for molding or placement on the production belt for transportation. The negative pressure adsorption can adapt to packaging boxes with different materials and surface characteristics, ensuring the firmness of the grab and avoiding the damage to the packaging box that may be caused by traditional mechanical grabbing methods.

[0021] 3. The second slide rail, the limit block, and the rotating handle are provided. The second slide rail is fixedly installed on the front and rear sides of the upper end of the base and is slidably connected to the bottom of the packaging machine. This provides a clear guide for the movement of the packaging machine, ensuring that the packaging machine can slide smoothly along a specific path without deviation or shaking when adjusting its position. After the packaging machine is positioned, the limit block can cooperate with the rotating handle to further enhance the stability of the packaging machine. When the rotating handle rotates and is stuck on the second slide rail, the limit block can prevent the packaging machine from being slightly displaced by external forces, ensuring that the packaging machine will not move out of position during packaging operations.

[0022] 4. In summary, this type of movable center-point packaging box making machine is equipped with structures such as a robotic arm, an auxiliary arm and a base. The center point of the packaging machine is adjusted through the base to make it consistent with the center point of the packaging box, which can better clamp the packaging box. Under the action of the double-headed screw 1, the robotic arm can move precisely in the horizontal direction, and through the drive of the motor 1, it can achieve operations of approaching or moving away from each other, so as to better complete the tasks of grabbing and carrying the packaging box. The auxiliary arm can extend and retract back and forth on the inside of the robotic arm, and cooperate with the robotic arm to adapt to the production needs of packaging boxes of different sizes and shapes. The suction nozzle on the auxiliary arm can ensure the stability and safety of the packaging box during the grabbing process, avoiding the damage to the packaging box that may be caused by traditional grabbing methods.
