[0025] In this way, after the production is completed, the floor box 100 and the sky box 200 successively arrive at the conveyor belt, the adjacent floor boxes and the adjacent sky boxes are arranged at intervals, the floor box and the sky box arrive at the floor box guide assembly and the sky box guide assembly respectively, the floor box guide assembly and the sky box guide assembly guide the floor box and the sky box respectively, the conveyor belt conveys the floor box and the sky box, the limit plate limits the sky box, the blocking limit structure limits the floor box, the cylinder rod of the lifting cylinder extends to drive the sky box moving structure to move downward, the sky box moving structure adsorbs the sky box, and the lifting cylinder is lifted. The cylinder rod of the lowering cylinder contracts, and the sky box moving structure drives the sky box to move above the ground box. The cylinder rod of the lifting cylinder extends, driving the sky box to buckle on the ground box. Then the lifting cylinder and the sky box moving structure are reset, and the blocking limit structure releases the limit. When the conveyor belt is transported, the buckled packaging box is driven to move to the pressure plate position. The pressure plate has an upwardly bent end to facilitate the packaging box to enter under the pressure plate. In the process of the conveyor belt driving the packaging box to continue to move, the sky box is buckled on the ground box through cooperation with the pressure plate, completing the buckling operation.

[0026] During implementation, the bottom box guide assembly includes two ground box guide plates 8, the sky box guide assembly includes two sky box guide plates 9, a front gantry 11 and a middle gantry 12 are fixedly installed on the conveyor belt bracket, the cross beams of the front gantry and the middle gantry are both fixed with support arms 13 downwardly, a support plate 14 is fixed at the lower end of the support arm, the support arm is fixedly connected to the sky box guide plate and the bottom box guide plate located on the inner side through a connecting piece, and the sky box guide plate and the bottom box guide plate located on the outer side are fixedly connected to the columns of the gantry through an external connecting piece.

[0027] In this way, the installation of the sky box guide plate and the bottom box guide plate is achieved through the front gantry and the middle gantry.

[0028] During implementation, the sky box moving structure includes a connecting plate 15, which is fixedly connected to the cylinder rod of the lifting cylinder, and a linear module 16 is fixed to the lower end of the connecting plate. Both sides of the slider of the linear module are fixed with mounting seats 17, and the mounting seats are installed with negative pressure suction cups 18. The linear module drives the slider to move, which is convenient for driving the sky box to move.
