[0059] Before describing the embodiments of the present invention, the prior art and its existing problems are further explained in detail:

[0060] Existing carton folding devices generally work on the principle of pneumatic cylinders, with a groove mold of preset size set up. The folded cardboard is pressed against the mold to obtain a formed carton.

[0061] The problem is that, when existing carton folding devices fold the cardboard, the pressing action exerts a significant impact force on the cardboard as it is pushed against the mold for forming, potentially damaging it and affecting the integrity of the product. Furthermore, the fixed-size groove molds of existing carton folding devices can only fold airplane boxes of a certain size. To automatically fold airplane boxes of other sizes, professionals must be present on-site to adjust the equipment, including accessories. This results in low efficiency and high costs in airplane box production.

[0062] In summary, the existing carton folding technology has problems such as the inability to guarantee the molding quality of the carton, high cost when producing carton boxes of multiple sizes, and low efficiency.

[0063] In view of this, an embodiment of the present invention provides a carton folding device, which can efficiently and automatically fold the carton while effectively ensuring the molding quality of the carton. First, the cardboard S0 to be folded in the embodiment of the present invention is introduced. In the embodiment of the present invention, the cardboard S0 to be folded can be an airplane box structure. Figure 2As shown, the cardboard S0 to be folded includes a bottom plate S1 and two side plate groups S2 connected to the two sides of the bottom plate respectively. The cardboard S0 to be folded is placed flat on the workbench 3; each side plate group S2 includes a first side plate S21, a second side plate S22a and a second side plate S22b, and the first side plate S21 of each group is arranged between the two second side plates S22a and the second side plates S22b of the same group; the second side plates S22a and the second side plates S22b of different groups are connected by a third side plate S23; the first side plate S21 includes an inner side plate S211 and an outer side plate S212; there is a first indentation on the first connecting line L1 between the inner plate S211 and the outer plate S212; there are card grooves C1a, C1b and a second indentation on the second connecting line L2 between the inner plate and the bottom plate; there is a third indentation on the third connecting line L3 between the third side plate S23 and the second side plate S22; there is a fourth indentation on the fourth connecting line L4 between the third side plate S23 and the bottom plate. The preset carton folding steps include: fixing the area of ​​the bottom plate S1 of the cardboard S0 to be folded flat on the workbench 3; raising the outer plate S212 and the second side plate S22 to a position perpendicular to the bottom plate S1; folding the inner plate S211 inward along the first indentation so that the edge of the inner plate S211 is inserted into the slots C1a and C1b, and simultaneously raising the third side plate S23 to a position perpendicular to the bottom plate S1 so that the third side plate S23 drives the second side plate S22 to move until the second side plate S22 is inserted into the cavity between the inner plate S211 and the outer plate S212. It is easy to understand that the edge of the inner plate S211 is provided with a protrusion S211a, which is embedded in the slot C1a, thereby fixing the inner plate S211 in a position perpendicular to the bottom plate S1. The protrusion S211a is provided corresponding to the card slot C1a. The number of the protrusion S211a and the card slot C1a can be provided correspondingly as needed. The embodiment of the present invention does not limit the number of the protrusion S211a and the card slot C1a.

[0064] The following describes the structure of the carton folding device. Figures 1 to 6 The carton folding device includes: a feeding module 1, a conveying module 2, a workbench 3 and a control module (not shown in the figure), wherein a paper folding module 4 is provided on the workbench 3; the control module is electrically connected to the feeding module 1, the conveying module 2, the paper folding module 4 and the workbench 3 respectively.

[0065] The control module is used to control the operation of the paper folding module 4 , the feeding module 1 , the conveying module 2 and the workbench 3 respectively.

[0066] The feeding module 1 is used to receive and carry the cardboard S0 to be folded.

[0067] The conveying module 2 is used to absorb the cardboard S0 to be folded from the feeding module 1, drive the absorbed cardboard S0 to be folded to move, and release the cardboard S0 after moving to the workbench 3.

[0068] The workbench 3 is used to carry the cardboard S0 to be folded delivered by the delivery module 2 and fix the bottom plate area of ​​the cardboard S0 to be folded.

[0069] The paper folding module 4 is used to fold each side panel area of ​​the folding paperboard S0 according to the preset paper box folding steps to obtain a formed paper box.

[0070] Specifically, combined Figures 1 to 6 Each structure is further explained. In an embodiment of the present invention, a support frame 5 is further provided for supporting each component. The control module of the carton folding device is connected to the support frame 5 as well as the feeding module 1, the conveying module 2, the paper folding module 4 and the workbench 3. The support frame 5 can be a hollow structure for accommodating and fixing the feeding module 1, the conveying module 2, the paper folding module 4 and the workbench 3. The support frame 5 can be composed of three hollow frames, namely, a first hollow frame R1, a second hollow frame R2 and a third hollow frame R3. The first hollow frame R1 accommodates the feeding module 1, the second hollow frame R2 accommodates the conveying module 2, the paper folding module 4 and the workbench 3, and the third hollow frame R3 accommodates the control module. It should be noted that the first hollow frame R1 and the second hollow frame R2 and the third hollow frame R3 can be fixedly connected or detachably connected. The specific method of detachable connection may include a snap-fit ​​connection, etc., so that the feeding module 1 can be separated from the conveying module 2, the paper folding module 4 and the workbench 3 to facilitate the feeding of the feeding module 1. In the detachable connection method, the electrical connection between the feeding module 1 and the control module can be a wireless connection method such as Bluetooth, or a circuit method in which the electrical connection is simultaneously connected when the feeding module 1 is snapped together with other modules. Correspondingly, in order to install the disassembled feeding module 1 into the carton folding device, a motion module can be provided at the bottom of the first hollow frame R1. The motion module can drive the first hollow frame R1 and the feeding module 1 to move to the bottom of the conveying module 2, so that the conveying module 2 can obtain and transmit the cardboard to be folded supplied by the feeding module 1.

[0071] For feeding module 1, if Figure 1 and Figure 3As shown, in this embodiment of the present invention, the feeding module 1 includes a carrier 11, a lifting structure 12, and a fixed bracket 13. The fixed bracket 13 is fixedly connected to the bottom of the first hollow frame R1, and the carrier 11 is connected to the fixed bracket 13 via the lifting structure 12. The carrier 11 is used to support at least one sheet of folded cardboard S0. The control module controls the lifting and lowering of the lifting structure 12, thereby driving the carrier 11 up and down relative to the fixed bracket 13. The carrier 11 is also provided with a friction structure to increase the friction between the folded cardboard S0 and the carrier 11, preventing the folded cardboard S0 from sliding down or falling off the carrier 11, thereby improving feeding reliability. Specifically, the friction structure can be an uneven frosted surface. It should be noted that the embodiment of the present invention does not limit the specific implementation of the lifting structure 12. It can be any structure that can achieve the lifting and lowering of the carrier 11 relative to the fixed bracket 13, such as a spiral lifting structure, a sliding lifting structure, or an articulated lifting structure. In one embodiment of the present invention, the lifting structure 12 can be an articulated structure. Specifically, the lifting structure 12 includes at least one articulated structure connected in series. like Figure 1 As shown, the lifting structure 12 is provided with a first hinge structure 121a and a second hinge structure 121b. The first hinge structure 121a includes a first rod 1211 and a second rod 1212, and the second hinge structure 121b includes a third rod 1213 and a fourth rod 1214. A through hole is provided at the middle position of the first rod 1211 and the middle position of the second rod 1212, and the two are hingedly connected. A through hole is provided at the middle position of the third rod 1213 and the middle position of the fourth rod 1214, and the two are hingedly connected. The first end of the first rod 1211 is movably connected to the second end of the fourth rod 1214, the first end of the second rod 1211 is movably connected to the second end of the third rod 1214, the first end of the third rod 1213 is fixedly connected to the bottom of the carrier 11, the bottom of the carrier 11 is provided with a first slide groove 111, the fixed bracket 13 is provided with a second slide groove 131, the second end of the first rod 1211 is fixedly connected to the On the fixed bracket 13, the second end of the second rod 1212 can slide in the second slide groove 131, and the first end of the fourth rod 1214 can slide in the first slide groove 111. The second slide groove 131 and the first slide groove 111 are arranged in parallel so that the first end of the fourth rod 1214 and the second end of the second rod 1212 can slide synchronously, thereby causing the vertical distances from the middle intersection of the first rod 1211 and the second rod 1212 and the middle intersection of the third rod 1213 and the fourth rod 1214 to the carrier 11 to change simultaneously, so that the carrier 11 can rise vertically to the first preset position, thereby achieving the lifting and lowering of the carrier 11. The first preset position is the position where the conveying module 2 can absorb the cardboard S0 to be folded.

[0072] In the embodiment of the present application, the feeding module 1 further comprises a positioning rail 14. The positioning rail 14 comprises two positioning rods, which are respectively arranged on both sides of the carrier 11, for positioning the paperboard S0 to be folded. Specifically, as shown in Figure 3 , a first preset position on the positioning rail 14 is provided with a first sensor 141 for detecting whether at least one paperboard S0 to be folded on the carrier 11 reaches the first preset position. The first sensor 141 adjusts the lifting height of the lifting structure 12 according to the thickness of the paperboard S0 to be folded on the carrier 11, which affects the suction of the conveying module 2 to the paperboard S0 to be folded. Optionally, as shown in Figure 3 , in an embodiment of the present application, the carrier 11 has a convex structure, specifically comprising a convex portion 1111 and a non-convex portion 1112 connected to the convex portion 1111. The two sides of the convex portion 1111 are clamped between the positioning rails 14. The upper surface of the carrier 11 is inclinedly arranged towards the positioning rails 14, so that the carrier 11 is clamped and positioned by the positioning rails 14 due to gravity. In a specific embodiment of the present application, the positioning rails 14 are arranged perpendicular to the fixed support 13, the fixed support 13 is arranged inclinedly relative to the bottom (i.e. the horizontal plane) of the first hollow frame R1, and the carrier 11 is arranged parallel to the fixed support 13, so that the paperboard S0 to be folded is adhered to the positioning rails 14 due to gravity, which on the one hand improves the reliability of paperboard positioning, and on the other hand further assists in limiting the paperboard S0 to be folded. It should be noted that the positioning rails 14 can be movably arranged on the fixed support 13, and the distance between the positioning rails 14 can be adjusted to adapt to paperboards S0 to be folded of different widths, so as to realize the supply of the feeding module 1 to paperboards S0 to be folded of various sizes. The distance adjustment mode between the positioning rails 14 can be that the positioning rails 14 are slidably arranged on the fixed support 13, and the distance adjustment is realized by sliding the positioning rails 14 on the fixed support 13. The embodiment of the present application does not limit the specific implementation mode of the distance adjustment between the positioning rails 14.

[0073] For the control module: the control module is arranged in the third hollow frame R3 at the lower left of the support frame 5, and is electrically connected to the paper folding module 4, the feeding module 1, the conveying module 2 and the workbench 3 through line connections. It can be understood that in an embodiment of the present invention, the control module may include at least one controller and a plurality of drive motors. Among them, the controller may be a processor such as MCU, MPU, etc., and the controller is used to control the movement of the drive motor. The plurality of drive motors are respectively connected to the paper folding module 4, the feeding module 1, the conveying module 2 and the workbench 3, and are used to drive the modules to which they are connected to move. In another embodiment of the present invention, there is also provided a paper box folding device APP installed on the terminal, which is used to communicate with the control module so that the control module controls the paper folding module 4, the feeding module 1, the conveying module 2 and the workbench 3 to work. Among them, the terminal may be a mobile phone, a tablet computer, etc., and the embodiment of the present invention does not impose specific restrictions.

[0074] Regarding the conveying module 2: The conveying module 2 includes a suction structure and a motion axis. The suction structure moves horizontally and vertically along the motion axis. When it moves to a first preset position, it absorbs the folded cardboard S0 on the carrier 11. After absorbing the folded cardboard S0, it moves to a second preset position to release the folded cardboard S0 onto the workbench 3. The first and second preset positions can be adaptively determined based on the range of the suction force of the suction structure to ensure that the folded cardboard S0 is not released prematurely or difficult to absorb.

[0075] In one embodiment of the present invention, Figure 4 As shown, the conveying module 2 includes: a first adsorption structure 21, a vertical lifting shaft 22 arranged vertically, and a horizontal feeding shaft 23 arranged horizontally. Among them, the first end of the vertical lifting shaft 22 is fixedly connected to the first adsorption structure 21, and the second end of the vertical lifting shaft 22 is slidably connected to the horizontal feeding shaft 23; the vertical lifting shaft 22 and the horizontal feeding shaft 23 are arranged perpendicular to each other. The vertical lifting shaft 22 drives the first adsorption structure 21 to move vertically up and down, and the horizontal feeding shaft 23 moves horizontally back and forth between the workbench 3 and the feeding module 1. Specifically, when the vertical lifting shaft 22 drives the first adsorption structure 21 to move vertically to the first preset position, the first adsorption structure 21 adsorbs the cardboard S0 to be folded, and the horizontal feeding shaft 23 drives the vertical lifting shaft 22 to be horizontally transferred to the second preset position after the first adsorption structure 21 adsorbs the cardboard S0 to be folded, and the first adsorption structure 21 releases the cardboard S0 to be folded. It should be noted that, in the embodiment of the present invention, there is no specific restriction on the way in which the conveying module 2 conveys the cardboard S0 to be folded. As long as it is a mechanism that can drive the first adsorption structure 21 to move back and forth between the first preset position and the second preset position, it can be driven by a motor such as an electric cylinder.

[0076] In an embodiment of the present invention, Figure 1As shown, one end of the horizontal feed shaft 23 is positioned above the workbench 3, and the other end of the horizontal feed shaft 23 is positioned above the feeding module 1. The vertical lift shaft 22 may be slidably connected to the horizontal feed shaft 23. The sliding of the vertical lift shaft 22 on the horizontal feed shaft 23 may be achieved by a motor driving a slider mounted on the vertical lift shaft 22 to slide on the horizontal feed shaft 23, but this is not specifically limited in this embodiment of the present invention. When the vertical lift shaft 22 moves on the horizontal feed shaft 23 to above the feeding module 1, it descends, driving the first suction structure 21 into the suction range of the feeding module 1. At this point, the control module controls the first suction structure 21 to suction. After the first suction structure 21 has suctioned the cardboard S0 to be folded, the vertical lift shaft 22 returns to its initial height. Subsequently, the vertical lift shaft 22 moves on the horizontal feed shaft 23 until it reaches above the workbench 3. The first suction structure 21 releases the cardboard S0, completing the transfer of the cardboard S0.

[0077] It should be noted that the embodiment of the present invention does not limit the specific implementation of the first adsorption structure 21. It can be achieved by using the opening of an air valve to control the suction cup to generate an air pressure difference for adsorption. For example, in one embodiment of the present invention, the first adsorption structure 21 may include at least one suction cup and an air valve used in conjunction with it. The air valve is opened or closed to control the adsorption or release of the suction cup. In order to improve the reliability of adsorption and prevent the folded cardboard S0 from falling off the first adsorption structure, Figure 4 As shown, the first adsorption structure 21 may include four suction cups 21a, 21b, 21c, and 21d.

[0078] In yet another embodiment of the present invention, Figure 4The device also includes a pushing mechanism 6. One end of the pushing mechanism 6 is slidably set on the horizontal feeding shaft 23, and the pushing mechanism 6 is used to push the formed paper box away from the workbench 3 before the next cardboard S0 to be folded reaches the workbench 3. The pushing mechanism 6 is arranged on the left side of the vertical feeding shaft close to the workbench. The pushing mechanism 6 includes a horizontal pushing shaft 61, a vertical pushing shaft 62 and a pushing rod 63. The horizontal pushing shaft 61 is arranged parallel to the horizontal feeding shaft 23, and the other end of the horizontal pushing shaft 61 is connected to the pushing rod 63. One end of the vertical pushing shaft 62 is slidably set on the horizontal feeding shaft 23, and the other end of the vertical pushing shaft 62 is connected to one end of the horizontal pushing shaft 61. The pushing rod 63 is a vertically arranged rod-shaped structure, which is used to push the formed paper box out of the workbench 3. Optionally, in order to ensure the automation and continuity of feeding and output and improve the efficiency of paper box folding, the pushing mechanism 6 can only include the aforementioned push rod 63 and the horizontal pushing shaft 61. One end of the horizontal pushing shaft 61 is fixedly connected to the vertical lifting shaft 22, so that when the vertical lifting shaft 22 moves toward the workbench 3 on the horizontal feeding shaft 23, it will drive the horizontal pushing shaft 61 to move together, thereby driving the pushing mechanism 6 to move above the workbench 3 and push out the formed paper box.

[0079] Regarding the workbench 3: In the embodiment of the present invention, the workbench 3 and the paper folding module 4 are arranged in the second hollow frame R2 of the support frame 5. The workbench 3 is arranged horizontally, as shown in FIG. Figure 5As shown, the workbench 3 includes four slide rail structures and a fixed plate. The fixed plate is used to fix one end of the folding mechanism. The slide rail structure is used to drive the adjustment of the distance between the fixed plates, and ultimately drive the adjustment of the distance between the folding mechanisms correspondingly set on each fixed plate, thereby realizing the folding of airplane boxes of various lengths and widths without the need for manual on-site replacement of origami machine parts. The four slide rail structures include a first longitudinal slide rail 311a, a second longitudinal slide rail 311b, a first transverse slide rail 312a, and a second transverse slide rail 312b. The first longitudinal slide rail 311a is arranged parallel to the second longitudinal slide rail 311b, and the first transverse slide rail 312a and the second transverse slide rail 312b are arranged perpendicular to the first longitudinal slide rail 311a and the second longitudinal slide rail 311b. A first fixing plate 320a, a second fixing plate 320b, a third fixing plate 320c, and a fourth fixing plate 320d are symmetrically disposed on the first transverse rail 312a and the second transverse rail 312b, respectively. Each of the four fixing plates 320a, 320b, 320c, and 320d is provided with a folding mechanism. The four fixing plates 320a, 320b, 320c, and 320d and the area enclosed by them constitute the working area of ​​the workbench 3. The four fixing plates 320a, 320b, 320c, and 320d can slide on the first transverse rail 312a and the second transverse rail 312b under the control of a control module. The first transverse rail 312a and the second transverse rail 312b can slide on the first longitudinal rail 311a and the second longitudinal rail 311b, respectively. This allows for adjustable relative distances between the four fixing plates 320a, 320b, 320c, and 320d. Among them, the distance adjustment can be achieved by the control instructions received by the control module, such as the user inputting the size parameters of the paper box in the application of the mobile phone connected to the control module, so that the control module adjusts the distance according to the size parameters, so that the workbench 3 can be suitable for various length and width sizes of cardboard to be folded. It should be noted that the embodiment of the present invention does not limit the specific implementation method of the distance adjustment between the first longitudinal slide 311a, the second longitudinal slide 311b, the first transverse slide 312a and the second transverse slide 312b. It is easy to understand that in order to achieve the relative sliding of the slides and thus adjust the size of the working area of ​​the workbench, the workbench 3 is also provided with at least three screw rods 35a, 35b, 35c, wherein the screw rods 35a, 35b are respectively arranged parallel to the first longitudinal slide 311a and the second longitudinal slide 311b, and the screw rod 35c is arranged parallel between the first transverse slide 312a and the second transverse slide 312b.

[0080] It should be noted that the embodiment of the present invention does not impose any specific restrictions on the structure of the workbench 3. The slide rail and screw rod structure in the workbench 3 can also be replaced with a module or other structure, as long as it can support the origami modules and adjust the distance between the origami modules. Considering that in order to better support the origami modules, at least four screw rods or modules or other structures can be provided in both the horizontal and vertical directions, and the distance between the screw rods or modules or other structures provided in the horizontal and vertical directions can be adjusted.

[0081] In the embodiment of the present invention, Figure 5 As shown, a second adsorption structure is also provided on the workbench 3. The second adsorption structure is used to adsorb the bottom plate area of ​​the cardboard S0 to be folded. In the embodiment of the present invention, the second adsorption structure can be four adsorption structures respectively provided on the four fixed plates 320a, 320b, 320c, and 320d, namely, the second adsorption structure 33a, the second adsorption structure 33b, the second adsorption structure 33c, and the second adsorption structure 33d, so as to adsorb the edge area of ​​the bottom plate of the cardboard to be folded. In another embodiment of the present invention, the second adsorption structure can also be provided at the center of the square area surrounded by the four fixed plates 320a, 320b, 320c, and 320d, and the embodiment of the present invention does not impose specific restrictions. Similar to the first adsorption structure 21 in the aforementioned embodiment, the second adsorption structure may include a suction cup and a corresponding air valve, and the air valve controls the adsorption or release of the suction cup by opening or closing. It is easy to understand that the opening and closing of the adsorption of the second adsorption structure can be controlled by the control module to cooperate with the conveying module 2 and the pushing mechanism 6, so that when the conveying module 2 releases the cardboard to be folded, the falling cardboard to be folded can be adsorbed in time by utilizing the effect of the pushing airflow when it is released, and after the folding mechanism is folded and reset, the formed paper box can be released in time to facilitate the pushing mechanism 6 to perform the pushing action.

[0082] For Origami Module 4: Figure 5As shown, the paper folding module 4 includes multiple folding mechanisms, one end of each folding mechanism being movably mounted on a fixed plate. The other end of each folding mechanism can be moved around the fixed plate in planes perpendicular to the workbench 3 toward the bottom area of ​​the cardboard S0 to be folded, until the other end of the folding mechanism is perpendicular to the workbench 3. The structure of each folding mechanism is adapted to the shape of the cardboard S0 to be folded. In the initial state, each folding mechanism is flat on the workbench 3, with the bottom area of ​​the cardboard S0 to be folded covering the middle area of ​​the workbench 3. The second suction structure on the fixed plate suctions the edge area of ​​the bottom area of ​​the cardboard S0 to be folded, securing the bottom area of ​​the cardboard S0 to the workbench 3. Each side panel of the cardboard S0 to be folded is laid flat on the corresponding folding mechanism. One end of the folding mechanism is set on the fixed plate. When driven by a driving device such as a motor, the other end of the folding mechanism rotates around the fixed plate in various planes perpendicular to the workbench 3 toward the bottom plate area of ​​the cardboard S0 to be folded, thereby pressing down, erecting or pushing inward on the side panels in the side panel group S2 at the corresponding position, and finally realizing the folding of the first side panel S21, the second side panel S22a, S22b and the third side panel S23 of each side panel group S2 respectively, and finally obtaining a shaped paper box with the protrusion S211a on the edge of the outer panel S212 engaged in the card slot C1a, and the second side panels S22a and S22b engaged in the cavity between the inner panel S212 and the outer panel S212.

[0083] In an embodiment of the present invention, Figure 5 As shown in Figure 6, the multiple folding mechanisms include two groups of folding mechanisms. One group of folding mechanisms corresponds to a group of side panel groups S2, wherein folding mechanism group 410a corresponds to side panel group S2a. It is easy to understand that the two groups of folding mechanisms corresponding to different side panel groups S2 are symmetrically arranged relative to the center of the bottom plate area of ​​the cardboard to be folded S0. The two groups of folding mechanisms have the same structure, only mirrored. Taking folding mechanism group 410a located on the left side of the workbench 3 as an example, folding mechanism group 410a includes a first side panel folding mechanism 411, two second side panel folding mechanisms 412a and 412b, and two third side panel folding mechanisms 413a and 413b. 412a and 413a are arranged on the fixed plate 320a, while 412b and 413b are arranged on the fixed plate 320b. The first side panel folding mechanism 411 is provided with a bending structure 4111. In the unfolded state, the cardboard to be folded S0 covers both groups of folding mechanisms 410.

[0084] During folding, first, the first side panel folding mechanism 411 moves toward the bottom panel area to a position perpendicular to the bottom panel area. At the same time, different groups of second side panel folding mechanisms 412a and 412b move relative to each other to positions perpendicular to the bottom panel area, thereby achieving the first side panel folding mechanism 411 erecting the outer panel S212 to a position perpendicular to the bottom panel S1, and the second side panel folding mechanisms 412a and 412b respectively erecting the second side panels S22a and S22b to a position perpendicular to the bottom panel S1.

[0085] Subsequently, the bending structure 4111 moves inward around the first side panel folding mechanism 411 to press the inner panel S211 inward and downward, so that the protrusion S211a on the edge of the inner panel S211 is engaged in the slot C1a. At the same time, the third side panel folding mechanisms 413a and 413b move together with the center line of the workbench 3 parallel to the transverse rails 312a, 312b as the axis until it is perpendicular to the bottom panel area, thereby erecting the third side panel S23 to a position perpendicular to the bottom panel S1 through the third side panel folding mechanisms 413a, 413b, so that the third side panel S23 drives the second side panel S22 to move to the gap between the inner panel S211 and the outer panel S212. At this point, the protrusion S211a on the edge of the inner panel S211 is engaged in the slot C1a and the second side panel S22 is engaged in the gap between the inner panel S211 and the outer panel S212, thereby obtaining a formed paper box.

[0086] It should be noted that, corresponding to the aforementioned preset carton folding steps, the erection of the outer panel S212 by the first side panel folding mechanism 411 can be performed simultaneously with the erection of the second side panel S22 by the second side panel folding mechanisms 412a and 412b. Furthermore, the erection of the third side panel S23 to a position perpendicular to the bottom panel S1 by the third side panel folding mechanisms 413a and 413b can be performed before the first side panel folding mechanism 411 folds the inner panel S211 inward along the first indentation, thereby facilitating the insertion of the second side panel S22 into the cavity between the inner panel S211 and the outer panel S212.

[0087] In one embodiment of the present invention, Figure 5As shown, a support member 34 is further provided on the workbench 3 near the card slot C1a. The support member 34 is arranged corresponding to the bending structure 4111. The support member 34 includes a support plane. The support plane is tilted upward at an angle relative to the workbench 3, and is used to tilt the bottom plate S1 to raise the card slot C1a, facilitating the insertion of the protrusion S211a into the card slot C1a. Considering that the card slot C1a is generally small, it is difficult to smoothly insert the protrusion S211a on the edge of the inner plate into the card slot C1a by directly pressing down on the inner plate. Therefore, a support member 34 can be further provided near the card slot C1a. The support member 34 supports the cardboard away from the workbench 3, while the bending structure 4111 presses down on the cardboard toward the workbench 3. The support member 34 and the bending structure 4111 work together to make it easier for the protrusion S211a on the edge of the inner plate S211 to insert into the card slot C1a, thereby preventing damage to the cardboard caused by violent punching.

[0088] In one embodiment of the present invention, Figure 1The third hollow frame R3 shown is provided with a chassis, a control module is provided in the chassis, and function keys are provided on the outer surface of the chassis. The function keys include emergency stop, switch, debug and reset, wherein the emergency stop is used to urgently stop the operation of the carton folding device, the switch is used to open or close the carton folding device, the debug is used to debug one or more modules in the carton folding device separately, and the reset is used to control the modules in the carton folding device to return to the initial state so as to fold the next cardboard to be folded. The function key can be a physical button or a virtual button displayed on a function interface. The function interface can be used to control the carton folding device, such as resetting one or more modules in the device, or for inputting the type and size parameters of the cardboard to be folded. The process of folding a cardboard to be folded into a formed carton by the carton folding device of an embodiment of the present invention is described as follows: First, start the power supply, turn on the carton folding device, and press the reset button on the chassis to reset the various modules of the carton folding device. Optionally, you can also select the carton model through a preset application on a terminal that is communicatively connected to the carton folding device and then click the reset button, so that the carton folding device adjusts the relative positions of the first longitudinal slide 311a, the second longitudinal slide 311b, the first transverse slide 312a, and the second transverse slide 312b according to the selected carton model. After the reset is completed, it enters the waiting working state. After that, toggle the switch of the feeding module 1, which can be set on the chassis, and the carrier 11 automatically rises until the first sensor 141 detects that the cardboard to be folded has reached the first preset position. Click the start button on the chassis or in the preset program to enable the carton folding device to start the folding work. During the folding process, the control module first controls the vertical lifting shaft 22 to move along the horizontal feed shaft 23, driving the first suction structure 21 to move above the feeding module 1. The control module then controls the vertical lifting shaft 22 to descend and controls the air valves of the suction cups 21a, 21b, 21c, and 21d, allowing them to absorb the folded cardboard S0 on the support 11. The control module then controls the vertical lifting shaft 22 to rise to its initial height and then controls the horizontal feed shaft 23 to move the folded cardboard S0 above the workbench 23. The control module then controls the vertical lifting shaft 22 to descend and closes the air valves of the suction cups 21a, 21b, 21c, and 21d, allowing the folded cardboard S0 to fall to the workbench due to gravity. The control module controls the opening of the control valves of the second adsorption structure 33a, the second adsorption structure 33b, the second adsorption structure 33c, and the second adsorption structure 33d to fix the bottom area of ​​the cardboard S0 to be folded on the area surrounded by the longitudinal slide rails 311a, the longitudinal slide rails 311b, the transverse slide rails 312a, and the transverse slide rails 312b. At the same time, the control module controls the vertical lifting shaft 22 to rise to the aforementioned initial height.Subsequently, the control module controls the first side panel folding mechanism 411 to move toward the bottom plate area to a position perpendicular to the bottom plate area. Simultaneously, different groups of second side panel folding mechanisms 412a and 412b move relative to each other to positions perpendicular to the bottom plate area. This allows the first side panel folding mechanism 411 to raise the outer side panel S212 to a position perpendicular to the bottom plate S1, while the second side panel folding mechanisms 412a and 412b respectively raise the second side panels S22a and S22b to positions perpendicular to the bottom plate S1. Simultaneously, the control module controls the horizontal feed shaft 23 to move above the feeding module 1 to perform the material removal operation. Subsequently, the bending structure 4111 moves inward around the first side panel folding mechanism 411 to press the inner side panel S211 inward and downward, causing the protrusion S211a on the edge of the inner side panel S211 to engage with the slot C1a. Afterwards, the third side panel folding mechanisms 413a and 413b move together around the centerline of the workbench 3, which is parallel to the first transverse rail 312a and the second transverse rail 312b, until they are perpendicular to the bottom plate area. The third side panel folding mechanisms 413a and 413b then raise the third side panel S23 to a position perpendicular to the bottom plate S1, allowing the third side panel S23 to drive the second side panel S22 to move until it fits into the gap between the inner side panel S211 and the outer side panel S212. At this point, the carton is folded. Finally, the control module controls each folding mechanism to return to its initial position, controls the second adsorption structure to control the air valve, and finally controls the horizontal push shaft 61 to move, driving the push mechanism 6 to push the formed carton out of the workbench 3. Simultaneously, as the previous cardboard to be folded is folded, the next cardboard to be folded is fed into the workbench 3.

[0089] An embodiment of the present invention further provides a carton folding method, which is based on the carton folding device in the aforementioned embodiment and is specifically executed by a control module of the carton folding device. The method includes the following steps:

[0090] Step A: When receiving the opening instruction, the feeding module 1 is controlled to absorb the cardboard S0 to be folded and drive the cardboard S0 to be folded to move.

[0091] Step B: When it is determined that the feeding module 1 moves to the first preset position relative to the conveying module 2 , the conveying module 2 is controlled to absorb the cardboard S0 to be folded and drive the cardboard S0 to be folded to move.

[0092] Step C: When it is determined that the conveying module 2 moves to the second preset position relative to the workbench 3 , the conveying module 2 is controlled to release the cardboard S0 to be folded.

[0093] Step D: Control the workbench 3 to receive and fix the bottom plate area of ​​the cardboard S0 to be folded.

[0094] Step E: Control the paper folding module 4 to fold each side panel area of ​​the folding paperboard S0 according to the preset paper box folding steps to obtain a formed paper box.

The carton folding method of the embodiment of the present invention adopts the adsorption and conveying method to transport the cardboard to be folded, which simplifies the structure of the carton folding machine, improves the efficiency of carton folding, and reduces the damage to the cardboard material during the folding process.

[0096] Furthermore, in an embodiment of the present invention, the workbench includes a fixing portion; the fixing portion is arranged around the bottom plate area; the origami module includes multiple folding mechanisms; the size of the fixing portion can be adjusted, thereby driving the position adjustment of the folding mechanism, so that automatic folding of aircraft boxes of various sizes can be achieved without manually replacing accessories.

[0097] Furthermore, in an embodiment of the present invention, the feeding module includes: a carrier and a positioning railing; the carrier is used to carry the cardboard to be folded; the positioning railings are arranged on both sides of the carrier to position the cardboard to be folded, and the distance between the positioning railings can be adjusted, so as to realize the supply of cardboard to be folded of various sizes.
