[0016] (1) The egg carton is conveyed to the working range of the labeling machine. The labeling machine affixes labels to the egg carton. The labeled egg carton is then conveyed to the inside of the support frame. The servo motor drives the rotating shaft to rotate, which in turn drives the L-shaped frame to rotate. Driven by the rotating shaft, the L-shaped frame rotates the first cylinder, transmission rod, first slider, and a set of electric suction cups above the egg carton. The first cylinder drives the transmission rod to move, which in turn drives the first slider to move under the sliding support of the L-shaped frame. When the first slider moves the set of electric suction cups to the surface of the egg carton, the electric suction cups are activated to pick up the egg carton. The first cylinder is then activated in the opposite direction, and under the support of the L-shaped frame, it drives the transmission rod to move. The transmission rod drives the first slider, electric suction cups, and egg carton to rise away from the surface of the first conveyor. The servo motor is then activated in the opposite direction, and under the support of the first base plate, the servo motor... The motor drives the rotating shaft to rotate, which in turn drives the L-shaped frame, the first cylinder, the electric suction cup, the first slider, and the egg packaging box to rotate. The egg packaging box enters the surface of the two sets of clamping arms through the U-shaped groove. The dual-shaft cylinder, supported by the connecting block, drives the two sets of clamping arms to clamp the egg packaging box. The first motor, supported by the support plate, drives the connecting block to rotate. The connecting block drives the dual-shaft cylinder, the clamping arms, and the clamped egg packaging box to rotate, flipping the egg packaging box. The electric suction cup picks up the flipped egg packaging box and moves it to the surface of the second conveyor through the rotation of the rotating shaft driven by the servo motor. The second conveyor is opened, moving the egg packaging box to the working range of the labeling machine. The labeling machine is opened to apply the label to the other side of the flipped egg packaging box. This realizes the automatic labeling machine to quickly transport the egg packaging box, which facilitates the automatic flipping of the egg packaging box for labeling and shortens the time for labeling both sides.

[0017] (2) The egg cartons finished with stickers are conveyed by the second conveyor to the space between two sets of pressing belts. The second motor drives the electric wheel to rotate, which in turn drives the pressing belts to rotate. The pressure plate, supported by the springs of the support blocks, elastically tensions the pressing belts to facilitate the compaction of the stickers on the surface of the egg cartons. The compacted egg cartons are then conveyed by the pressing belts into the storage bin. This process enables the automatic sticker machine to conveniently compact the stickers on the egg cartons, improving the quality and efficiency of the sticker application.
