Description

Technical Field

[0001] The utility model belongs to the technical field of packaging carton folding, and in particular relates to a packaging carton folding device. Background Art

[0002] Packaging cartons are mostly rigid paper containers made of corrugated cardboard. Packaging cartons have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, and have become the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Packaging cartons are green and environmentally friendly products, which are beneficial to environmental protection and convenient for loading and unloading and transportation. In real life, packaging cartons need to be folded before use. First, the plate-shaped packaging carton is stretched open to form a packaging carton cube, and then the two sides with smaller bottom areas of the packaging carton cube are folded inward, and then the two sides with larger areas are folded inward, and finally a piece of tape is pasted on the joint gap between the two sides with larger areas. This process is usually completed manually, but it is also completed mechanically in the prior art.

[0003] For example, a packaging carton folding device and a processing method thereof with publication number CN111805968A in the prior art include a folding mechanism, a storage mechanism, a unloading mechanism, a mounting frame, a carton board, and a packaging carton body. The folding mechanism is installed in the inner cavity of one end of the mounting frame, and the unloading mechanism is installed on the top of the other end of the mounting frame. The storage mechanism is installed on the side of the mounting frame close to the end of the folding mechanism, and the carton board is placed on the storage mechanism. The carton board is processed by the folding mechanism to form a packaging carton body; the packaging carton folding device places the carton board through the storage mechanism, automatically loads the carton board through the loading suction cup of the folding mechanism and forms the carton board into a square cylinder, automatically folds the carton board through the first folding plate, the second folding plate, the third folding plate, and the fourth folding plate, and automatically unloads the carton through the unloading mechanism. The packaging carton folding device has a high degree of automation and effectively improves the production efficiency of the packaging carton.

[0004] However, there are still certain deficiencies in the above-mentioned prior art: in the process of realizing the folding of the packaging carton, the above-mentioned prior art only realizes the folding of the side edges of the bottom of the packaging carton, and cannot realize the tape treatment after the folding, so the functionality of the device is not perfect and needs further improvement. Utility Model Content

[0007] Optionally, a convex plate is symmetrically slidably arranged on the top surface of the workbench, and a rectangular notch is opened at the lower end of the convex plate.

[0008] Optionally, the column one, column two and the inner side of the convex plate are all provided with a stabilizing plate, and the front end of the stabilizing plate is provided with a flippable rotating plate, so that the lower side plate of the carton can be folded by the rotating plate.

[0009] Optionally, the suction cups 1 on the column 1 and the column 2 cooperate to stretch and unfold the plate-like carton to form a square cylindrical carton, thereby facilitating the subsequent folding of the side edges of the lower end of the carton.

[0010] Optionally, all of the stabilizing plates are at the same height, and the stabilizing plates may be flush with the fold at the lower end of the square tubular carton.

[0011] Optionally, the suction cup 2 can extend into the interior of the square cylindrical carton from the upper opening.

[0012] Optionally, the roller is tangent to the side of the square cylindrical carton, so that the extra section of tape on both sides can be attached to the side of the carton through the roller.

[0013] In summary, this application has the following beneficial effects:

[0035] When this scheme is running, first start the ball screw slide 4, so that the suction cup 10 on the column 6 gradually approaches and contacts the plate-like carton 33 in the vertical state at the front end of the feeding mechanism 2 (and the contact position is the middle of the larger area of ​​the middle part of the plate-like carton 33). When the plate-like carton 33 is adsorbed, start the ball screw slide 4 in the reverse direction, so that the plate-like carton 33 gradually moves away from the feeding mechanism 2. When the other side of the plate-like carton 33 exceeds the suction cup on the column 2 7, stop the ball screw slide 4 and start the ball screw slide 2 5, so that the suction cup on the column 2 7 gradually moves to the middle of the other side of the plate-like carton 33. When the suction cup on the column 2 7 moves to the middle of the larger area part on the other side of the plate-like carton 33, the telescopic rod 1 8 is started, so that the telescopic rod 1 8 pushes the mounting plate 9 and the suction cup on the column 2 7 absorbs the larger area part in the middle of the other side of the plate-like carton 33, and then the ball screw slide 1 4 and the ball screw slide 2 5 are started at the same time, so that the plate-like carton 33 can be unfolded through the cooperation of the horizontal movement of the two suction cups perpendicular to each other. When the suction cups on both sides are opposite to each other, the ball screw slide 1 4 and the ball screw slide 2 5 are stopped. At this time, the plate-like carton 33 is fully unfolded to form a square The square cylindrical carton 34 is located directly below the rectangular plate 19, in the middle of the four stabilizing plates 13, and the fold of the lower side of the square cylindrical carton 34 is on the same horizontal plane as the top surface of the stabilizing plate 13. Then, the telescopic cylinders 11 on both sides are started, so that the telescopic cylinders 11 push the convex plate 12 to the side with a smaller area at the lower end of the square cylindrical carton 34. When the stabilizing plate 13 on the convex plate 12 is close to the side with a smaller area at the lower end of the square cylindrical carton 34, the telescopic cylinders 11 are stopped and the telescopic rod 15 on the convex plate 12 is started, so that the telescopic rod 15 on the convex plate 12 gradually rotates the rotating plate 14 outward. Finally, the rotating plate 14 and the stabilizing plate 13 are horizontal. During the rotation of the rotating plate 14, the rotating plate 14 first contacts the side with the smaller area at the lower end of the square cylindrical carton 34, and then rotates together with the side with the smaller area at the lower end of the square cylindrical carton 34, so that the side with the smaller area at the lower end of the square cylindrical carton 34 is folded to the inner side of the lower end of the square cylindrical carton 34 to a horizontal state, and then the telescopic rod 3 18 is started, so that the telescopic rod 3 18 pushes the rectangular plate 19 to extend from the upper end opening of the square cylindrical carton 34 and finally makes the suction cups 20 on both sides contact and adsorb the folded side of the lower end of the square cylindrical carton 34;

[0036] Then, the telescopic cylinder 11 and the telescopic rod 2 15 on the convex plate 12 are started to reset the convex plate 12 and the rotating plate 14 (i.e., away from the square cylindrical carton 34). At this time, the side with a smaller area at the lower end of the square cylindrical carton 34 is still in an inward folded state due to the action of the suction cup 20. Then, the telescopic rod 2 15 on the column 1 6 and the column 2 7 is started, and then the side with a larger area at the lower end of the square cylindrical carton 34 is folded inward to a horizontal state by the same principle, and the lower end surface of the square cylindrical carton 34 is folded inward. After the two sides with larger areas are folded, a gap is formed just above the push plate 23, and then the automatic tape cutter 32 is started to extend a certain length of tape. Since the discharge port of the automatic tape cutter 32 is directly facing between the two limit plates 30 and the adhesive surface faces upward, the extended tape moves forward along between the limit plates 30 and finally falls on the push plates 23 on both sides. Then the telescopic rod 4 22 is started, so that the telescopic rod 4 22 pushes the push plate 23 gradually toward the gap formed at the lower end of the square cylindrical carton 34. The tape is moved and finally contacts with it. During the contact process, the limiting plates 30 on both sides will be compressed back into the receiving groove 29 by the lower end of the square cylindrical carton 34. At the same time, the tape is also attached to the gap, and there is still a part of the tape at both ends. Then the telescopic rods 5 26 on both sides are started, so that the telescopic rods 5 26 push the rollers 28 to move upward, so that the rollers 28 on both sides attach the tapes on both sides along the two side walls of the square cylindrical carton 34, and then the tape attachment is completed, and then the suction cups 10 on both sides are closed, and the suction is reset. The disk 10, the roller 28, the push plate 23 and the rotating plate 14 on the column 1 6 and the column 2 7, due to the adsorption of the suction cup 2 20, the carton with the tape will not fall off, and then the ball screw slide 3 17 is started to move the carton to the top of the unloading and transporting mechanism 3, and then the suction cup 20 and the retractable rod 3 18 are closed to drop the carton onto the rubber roller of the unloading and transporting mechanism 3, so as to realize the unloading of the carton, and then the folding and taping processing of the plate-shaped carton 33 is also realized, and the above operation can be repeated.
