[0030] The working principle of this paper box folding and forming device is as follows: the cardboards are stacked in the storage bin 22, and the cardboard at the bottom is located between the two feeding ports 221. When the cardboard is loaded, the first cylinder 26 drives the pushing plate 23 to slide toward the storage bin 22 and pass through the feeding port 221 to extend into the storage bin 22 and abut against the cardboard at the bottom. The cardboard at the bottom is pushed by the pushing plate 23 to pass through the other feeding port 221 and slide toward the guide channel on the loading support plate 21. When the cardboard slides into the guide channel, the guide plates 24 on both sides of the cardboard play a guiding and positioning role for the sliding of the cardboard, so that the cardboard slides stably toward the positioning plate 25 in the guide channel 27. When the cardboard slides to the end and is aligned with the positioning plate 25, the cardboard is pressed against the positioning plate 25. When the plates 25 abut against each other, the loading operation of the cardboard is completed. At this time, the cardboard is located below the first forming plate 31 and the bottom plate portion 8a of the cardboard is aligned with the forming port 211. In the above-mentioned cardboard loading process, the push plate 23, the guide plate 24 and the positioning plate 25 can ensure the accuracy of the cardboard position after loading. When the side panel forming operation of the carton is performed, the second cylinder 34 drives the first forming plate 31 to move downward and abut against the bottom plate portion 8a of the cardboard. As the first forming plate 31 continues to move downward, the first forming plate 31 pushes the cardboard through the forming port 211. At this time, the transfer plate 61 is located between the two left and right forming plates 32 under the cooperative drive of the motor 63 and the fourth cylinder 64, and the connecting piece forming rod 33 When the third cylinder 35 drives the swing to be located on one side of the left and right forming plates 32, and the cardboard passes through the forming port 211 under the push of the first forming pressing plate 31 and continues to move downward, the connecting piece 8c of the cardboard contacts the connecting piece forming rod 33 and is folded inward under the action of the connecting piece forming rod 33. At the same time, the side panels 8b of the left and right sides of the cardboard contact the upper ends of the active surface forming plates and are folded inward under the action of the left and right forming plates 32. The side panels 8b of the front and back sides of the cardboard contact the vertical parts of the transfer plate 61 and are folded inward under the action of the transfer plate 61, completing the forming operation of the side panels of the carton, so that the carton with the formed side panels is located in the side panel forming frame, and the first buckle forming operation of the carton is performed, that is, the front and back sides of the carton are performed. During the gusset plate forming operation, the fourth cylinder 64 drives the connecting piece forming rod 33 to swing outward, so that the connecting piece forming rod 33 leaves the left and right forming plates 32, and the fifth cylinder 44 drives the folding push plate 41 to move toward the gusset plate portion 8d of the front side of the side panel forming carton located in the side panel forming frame, and pushes the gusset plate portion 8d to fold inward 90 degrees. At the same time, the motor 63 drives the sliding plate 62 through the transmission screw to drive the transfer plate 61 to move in the direction away from the feeding mechanism 2. The gusset plate portion 8d on the rear side of the carton located in the transfer plate 61 contacts the first gusset plate forming plate 42 in the process of moving with the transfer plate 61 and folds inward 90 degrees under the action of the first gusset plate forming plate 42, and as the transfer plate 61 continues to move,The two gusset parts 8d at the front and back of the carton located in the transfer plate 61 and folded inward 90 degrees are kept in a folded state under the action of the first gusset forming plate 42 and drive the carton to move to the bottom of the second forming press plate 43, located between the two clamping assemblies 7, and the sixth cylinder 45 drives the second forming press plate 43 to move downward through the two first gusset forming plates 42 and contact the gusset parts 8d at the front and back of the carton, and push the two side panels at the front and back to continue to fold inward and fit with the inner walls of the side panels at the front and back of the carton, completing the forming operation of the gusset plates at the front and back of the carton, and carrying out the second gusset forming operation of the carton. During the secondary gusset plate forming operation, that is, when the gusset plate forming operation on the left and right sides of the carton is performed, after the second forming pressing plate 43 is reset, the transfer plate 61 drives the carton located in the transfer plate 61 to move away from the feeding mechanism 2 to between the two sets of second gusset plate forming mechanisms 5 under the drive of the motor 63, and the eighth cylinder 53 drives the driving plate 52 to move toward the carton and drives the second gusset plate forming plate 51 in an inclined state to swing upward under the drive of the ninth cylinder 54 to move toward the carton. In the process of the second gusset plate forming plate 51 moving, the second gusset plate forming plate 51 and the gusset plates on the left and right sides of the carton are in contact with each other. The gusset plate 8d on the left and right sides of the carton contacts and pushes the gusset plate 8d on the left and right sides of the carton to fold inward. At this time, the second gusset plate forming plate 51 moves to the top of the carton, and the ninth cylinder 54 drives the second gusset plate forming plate 51 to swing downward and push the gusset plate 8d on the left and right sides of the carton to continue to fold inward. At this time, the second gusset plate forming plate 51 swings into the carton, and then the eighth cylinder 53 drives the driving plate 52 to drive the second gusset plate forming plate 51 to move away from the carton, so that the second gusset plate forming plate 51 located in the carton moves toward the inner wall of the side plate on the left and right sides of the carton, thereby pushing the gusset plate 8d on the left and right sides of the carton. Continue folding to fit the inner walls of the left and right side panels of the paper box to complete the forming of the left and right gussets of the paper box. At this point, the cardboard folding and forming operation into a paper box is completed. It can be seen that this paper box folding and forming device can automatically and continuously complete the operation of folding the cardboard into a paper box. During the feeding operation, the cooperation of the push plate 23, the guide plate 24 and the positioning plate 25 ensures that the cardboard is accurately in the correct position during folding, thereby ensuring that the side panels, connecting piece 8c and gusset of the paper box can be correctly folded along the indentation to form the paper box, thereby ensuring the quality and efficiency of production.

When transferring between the surface gusset plate forming stations, the clamping plate 72, driven by the seventh cylinder 71, clamps the carton located at the front and rear gusset plate forming stations, that is, located below the second forming pressure plate 43, to temporarily fix the position of the carton. The supporting edge 12 will move to the left and right gusset plate forming stations, that is, to support the carton located between the two groups of second gusset plate forming mechanisms 5, to temporarily fix the position of the carton, so that the two transfer plates 61 can continuously transfer between the above three stations and continuously transfer the carton, thereby improving the efficiency of the carton integrity operation.
