Description

Technical Field

[0001] This utility model relates to the field of automatic box opener technology, specifically an automatic box opener with a folding function. Background Technology

[0002] Automatic case openers are efficient, stable, and safe mechanical devices that automate the unfolding and sealing of cases through steps such as case identification, case opening, and case closing.

[0003] Existing automatic carton openers are designed with a bottom support flipping function, which can fold the bottom of the carton to facilitate subsequent bottom gluing operations. During the flipping support process, the flipping heads at both ends need to flip synchronously to achieve the bottom folding. This bidirectional synchronous folding method can indeed improve folding efficiency.

[0004] However, this design is not flexible enough when only one side of the bottom box needs to be folded, and it cannot meet the operational requirements well. If only one side needs to be folded, the flipping head on the other end will also move at the same time. This not only wastes resources, but may also cause unnecessary mechanical wear or failure. This design has certain limitations on the types of cartons that need to be processed, reducing the applicability of the carton opener and the overall efficiency of the equipment. It needs to be optimized and improved. Utility Model Content

[0008] The adjustable flipping assembly is located at the front and rear ends of the inner side of the chassis. The adjustable flipping assembly includes a flipping head, a stop bar at the bottom end of the flipping head, and inclined sliders at both ends of the outer side of the stop bar. The adjustable flipping assembly is used to press the sides when the bottom of the carton is flipped.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1-4 As shown, this application provides an automatic carton opening machine with a folding function, including: a chassis 1, a feeding rack 2 installed at the front end of the chassis 1, a transfer suction cup 3 installed inside the chassis 1, and a finished product output rack 4 installed on the left side of the chassis 1.

[0027] A bidirectional pushing assembly is provided at the bottom inner side of the chassis 1. The bidirectional pushing assembly includes a support frame 1 6, a support frame 2 8 at the front end of the support frame 1 6, an electric slider 10 at the top end of the support frame 1 6, and a bottom push plate 15 at the top end of the electric slider 10. The bidirectional pushing assembly is used for folding the bottom of the carton blank.

[0028] The inner front and rear ends of the casing 1 are provided with adjustment and flipping components, and the adjustment and flipping components include a flipping head 18. The bottom end of the flipping head 18 is provided with a stop bar 19, and the outer ends of the stop bar 19 are provided with inclined sliders 21. The adjustment and flipping components are used to press the sides when the bottom of the carton is flipped.

[0029] Specifically, such as Figure 1As shown, the inner rear wall of the chassis 1 is connected to an unfolding limiting plate 5, which is used to open when the carton is transported. After the carton is folded, the adjacent surfaces will be on the same plane. Then the unfolding limiting plate 5 is used to limit the surface that is not adsorbed, so that the carton can be unfolded easily.

[0030] Specifically, such as Figure 2 As shown, support frame 6 is installed on the inner bottom of the chassis 1, and both the left and right ends of the inner side of support frame 6 are connected to bidirectional threaded adjustment rods 7. The bidirectional threaded adjustment rods 7 are used to adjust the distance between support frame 6 and support frame 8.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, a slide rail 9 is installed on the inner side of the support frame 6, and an electric slider 10 is slidably connected to the top of the slide rail 9. A rotating rod 12 is connected to the top of the electric slider 10. The electric slider 10 moves left and right on the inner side of the slide rail 9, and the rotating rod 12 on the inner side is controlled to rotate by an internally installed motor.

[0032] Specifically, such as Figure 3 As shown, a support plate 13 is provided at the top of the rotating rod 12, and a rotating connecting shaft 14 is installed at the top of the support plate 13. A bottom push plate 15 is connected to the outer side of the rotating connecting shaft 14, and an elastic connector 16 is connected to the inner bottom end of the bottom push plate 15. The support plate 13 can be rotated to adjust its position. The rotating connecting shaft 14 is used for the rotational support of the bottom push plate 15, and the inner elastic connector 16 is used for the reset of the bottom push plate 15, which can achieve the effect of reciprocating buffering, squeezing and folding.

[0033] Specifically, such as Figure 2 As shown, an electric slider 21 is installed at the top of the support frame 28. The top of the electric slider 21 has the same mounting structure as the top of the electric slider 10, and achieves the same function. The direction of action can be adjusted according to the actual situation.

[0034] Specifically, such as Figure 4 As shown, telescopic cylinders 17 are installed at both the front and rear ends of the inner side of the machine box 1. The flipping head 18 is connected to the top of the telescopic cylinder 17, and the bottom of the inner side of the flipping head 18 is connected to a stop bar 19. The telescopic cylinder 17 drives the flipping head 18 to rotate, and the stop bar 19 provides limiting support, so that the bottom of the carton can be flipped and sealed.

[0035] Specifically, such as Figure 4 As shown, the outer wall of the stop bar 19 is connected to a rubber ring 20, and the outer side of the stop bar 19 is slidably connected to a slanted slider 21. The outer side of the slanted slider 21 is connected to an elastic connecting rod 22. During the flipping and squeezing process, the rubber ring 20 contacts the carton to increase friction and improve the folding stability. The slanted sliders 21 on both sides are adjusted by side squeezing and pressing, which plays a compacting role on the inner folding plate.

[0036] In this embodiment: the bottom push plate 15 at the top of the support frame 1 6 and the support frame 2 8 are used in conjunction to perform unidirectional or opposite-directional movements, thereby achieving single-sided or double-sided folding, increasing the diversity of the flipping function. When the bottom cardboard box folding plate is folded by the connecting rod 19 of the flipping head 18, the side corners of the cardboard box are limited by the movable squeezing inclined slider 21 to achieve a stable squeezing effect and improve the neatness of the folding.

[0037] The specific solution is as follows: During the unpacking process of the carton blank, the transfer suction cup 3 moves the carton blank out of the feeding rack 2. After being unfolded by the unfolding limiting plate 5, before processing, according to the size of the carton blank, the bidirectional threaded adjusting rod 7 is rotated to adjust the position between the support frame 1 6 and the support frame 2 8. Then, depending on whether the inner folding plate is single-sided or double-sided, the forward direction of the electric slider 1 10 and the electric slider 2 11 is controlled to run in the same direction. During operation, the elastic compression of the bottom push plate 15 causes the inner folding plate to bend at the bottom of the carton blank. At this time, the telescopic cylinder 17 drives the flipping head 18 to rotate, flipping the bottom layer of the support. At the same time as flipping, the inclined slider 21 is close to the bottom corner of the carton to limit the movement of the corner, making the carton flip more flat. After flipping, it is glued inside the finished product output rack 4 and then sent out, completing the unpacking.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0039] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
