[0024] Preferably, a support limiting plate is fixed on one side of the support connecting plate, and a support positioning plate is fixed on the other side of the support connecting plate.

[0025] Working principle: After the product is loaded into the box, the box is transported forward through the box conveyor belt, the box limit cylinder is started, the piston rod of the box limit cylinder is extended, the box limit plate is moved between the two box fixed plates, the box is moved to the box top plate, and the outermost box is blocked by the box limit plate. When the specified number of boxes arrive at the box top plate, the box positioning cylinder is started, the piston rod of the box positioning cylinder is extended, the box positioning plate is moved between the two box fixed plates, and the box positioning plate blocks the box from reaching the box top plate position. After the specified number of boxes arrive at the box top plate, the box lifting motor is started, and the box lifting motor drives the box connecting plate to rotate. The box connecting plate pushes the box slider upward through the box push plate, and the box top plate moves upward The box body moves upwards, and the packaging box on the box body lifting plate moves upwards with the box body lifting plate. Since the lower end of the box body support plate is an inclined structure, when the packaging box moves upwards, it contacts the box body support plates on both sides and pushes the box body support plates close to the corresponding box body fixed plates to move. When the packaging box reaches the top of the box body support plate, the box body limit spring pulls the box body limit block to move, and the box body support plate returns to the initial position. The box body lifting motor drives the box body connecting plate to continue to rotate, the box body lifting plate descends, and the packaging box descends with the box body lifting plate. Due to the obstruction of the box body support plate, the packaging box stays on the box body support plate, the box body positioning cylinder is started, the piston rod on the box body positioning cylinder is shortened, the box body positioning plate returns to the initial position, the box body conveyor belt continues to operate, and the packaging box continues to reach the top of the box body lifting plate. When the specified number of packaging boxes After reaching the box body lifting plate again, the box body positioning cylinder is started again, and the box body positioning plate blocks the packaging box from reaching the box body lifting plate position again. The box body lifting motor drives the box body lifting plate to rise again, and the packaging box on the box body lifting plate reaches the box body support plate again and is neatly stacked with the previous packaging box. The cycle operation is carried out. When the specified number of packaging boxes are stacked on the box body support plate, the push lifting cylinder is started, the piston rod on the push lifting cylinder is extended, and the push plate descends. After the push plate reaches one side of the stacked packaging box, the push motor drives the push synchronous belt to rotate, the push slide moves, and the push plate moves with the push slide. The push plate moves the stacked packaging box to the support connecting plate, and the packaging box stops after reaching the support limit plate position. While the packaging boxes are stacked, the packaging boxes are formed into packaging boxes with two ends opened by the carton picking device. The bottom of the packaging box is supported by the carton conveying support plate. The box picking motor drives the box picking synchronous belt to rotate. When the box picking synchronous belt rotates, the box picking slide moves. After the box picking slide moves to the specified position, the box picking fixed plate and the box picking positioning plate are moved in a plane close to the packaging box. After the box picking fixed plate moves to the specified position, the box picking cylinder on the box picking fixed plate and the box picking positioning plate is started, the piston rod on the box picking cylinder extends, and the suction cup moves. After the suction cup is close to the surface of the packaging box, the suction cup is connected to the vacuum pump through the air pipe, and the vacuum pump is used to suck the vacuum at the suction cup position. Negative pressure is formed at the suction cup position, and the packaging box is sucked on the suction cup surface. The box picking motor drives the box picking synchronous belt to rotate again, and the box picking slide moves away from the carton conveying device.After the packaging box is grabbed by the suction cup, it is pulled out from the carton conveying device. After the packaging box moves to the designated position, the box taking and forming cylinder is started, the piston rod on the box taking and forming cylinder is extended, and the box taking and pushing rod drives the box taking and positioning plate to rotate. The box taking and positioning plate forms a 90-degree angle with the box taking and fixing plate. The packaging box is deformed as the box taking and positioning plate rotates. The packaging box unfolds in a diamond shape to form a packaging box with openings at both ends. The box taking and rotating motor drives the box taking and rotating shaft to rotate a certain angle. The packaging box moves with the box taking and sliding table to the position opposite to the stacked packaging boxes on the supporting connecting plate. The box entry limit motor is started, and the box entry limit motor drives the box entry limit synchronous belt to rotate. When the box entry limit synchronous belt rotates, the box entry limit push plate moves, and the box entry limit push plate enters the packaging box from the opening position on the right side of the packaging box, and enters the packaging box through the box entry limit push plate. The box supports the packaging box inside the box, and the box-entry positioning motor drives the box-entry positioning synchronous belt to rotate. When the box-entry positioning synchronous belt rotates, the box-entry positioning slide moves, and the box-entry positioning push plate moves with the box-entry positioning slide, and the box-entry positioning push plate pushes the stacked packaging box to move. After the packaging box enters the packaging box from the left opening of the packaging box, the packaging box on the right is blocked by the box-entry limit push plate, and the box-entry positioning motor drives the box-entry positioning synchronous belt to rotate again, and the box-entry positioning push plate returns to the initial position, and the box-entry limit motor drives the box-entry limit synchronous belt to rotate, and the box-entry limit push plate returns to the initial position, and the packaging box stays in the packaging box. The box-taking motor drives the box-taking synchronous belt to rotate again, and the box-taking slide moves toward the carton sealing device, and the carton sealing device seals the packaging box.
