Then, the third cylinder 11 drives the vacuum suction cup 13 to move upward and suck up the bottom box body 4. Then, the second cylinder 22 drives the connected clamping body 25 to separate from the box body 4. Then the third cylinder... The third cylinder 11 drives the vacuum suction cup 13 and the suction box 4 to move downwards. When the box 4 moves to contact the conveyor belt 15, the vacuum suction cup 13 releases the box 4. Then the third cylinder 11 drives the vacuum suction cup 13 to continue to descend until it moves to the initial position. The box 4 that falls on the conveyor belt 15 is transported away by the conveyor belt 15. Then the second cylinder 22 drives the connected clamping body 25 to reset. Then the first cylinder 21 drives the connected clamping body 25 to reset. At this time, the box 4 at the bottom is supported by the second cylinder 22 and the connected clamping body 25.

[0027] When there are too few boxes 4, the sensor 5 will not be able to detect the boxes 4. After receiving the feedback from the sensor 5, the control device of the packaging line where the automatic box dropping device is located will issue an alarm to remind the operator to add boxes in time.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
