[0025] Continue to refer to Figures 1 to 7 As shown in the figure, in this embodiment, the box folding fixed frame 1 includes a first bottom plate; on both sides of the top of the first bottom plate, a first vertical plate is connected respectively, and between the tops of the two first vertical plates, a first top plate is also connected; the side folding mechanism 2 includes two first fixed seats 21 and a second roller 22; at both ends of one side of the top of the first top plate, a first fixed seat 21 is installed respectively; the second roller 22 is rotatably connected between the two first fixed seats 21. As Figure 7 shown in the figure, two groups of second rollers 22 are installed between the two first fixed seats 21 on one side of the top of the first top plate, and the two second rollers 22 are distributed vertically. When an external manipulator or manual labor transfers the yellow leather box onto the box folding fixed frame 1, a downward pressure will be exerted on the yellow leather box, so that the sides on both sides of the bottom surface 106 of the yellow leather box are folded upward along the first crease 101 through the second roller 22, completing the folding and forming of the sides. At the same time, there are three columns of first vacuum suction cups 11 on the first top plate, with five in each column, which can adsorb and limit the bottom surface of the yellow leather box, facilitating the box folding rotation plate 6 to fold the rear end face and the top surface of the yellow leather box.

[0026] In one embodiment, on both sides of the folding box rotating plate 6 near one end of the folding box fixing frame 1, an extending fixing block 61 extends towards the folding box fixing frame 1; on one side of the extending fixing block 61, a first U-shaped notch with a U-shaped structure is formed, and a first rotating shaft is installed on the inner side of each of the two U-shaped vertical ends of the first U-shaped notch; the first folding lug mechanism 7 includes a first rotating push block 71, a rotating driving cylinder 72, a folding small ear assembly 73, and a first connecting block 74; the first connecting block 74 is arranged vertically below the extending fixing block 61, and the top of the first connecting block 74 is connected to the bottom of the extending fixing block 61; one side of the first rotating push block 71 is arranged in the first U-shaped notch, and both ends of the first rotating push block 71 are rotatably connected to the extending fixing block 61 through a first rotating shaft; a first fixing block 75 is installed at the lower part of one side of the first connecting block 74; the first fixing block 75 has a U-shaped structure, the U-shaped horizontal end of the first fixing block 75 is connected to the first connecting block 74, and a first connecting shaft is connected between the two U-shaped vertical ends of the first fixing block 75; the lower part of the rotating driving cylinder 72 is hinged to the first fixing block 75 through the first connecting shaft, and the output shaft of the rotating driving cylinder 72 is also drivingly connected with a first push rod 76; a second U-shaped notch is formed at the bottom of the first rotating push block 71, and a second connecting shaft is also connected between the inner walls on both sides of the second U-shaped notch; one end of the first push rod 76 is sleeved on the second connecting shaft; the folding small ear assembly 73 is installed on the first rotating push block 71.

[0027] As Figure 5 shown, in this embodiment, the first rotating push block 71 has a 90° fan-shaped structure, which is a profiling structure of the lugs on both sides of the rear end face 107 of the yellow leather box. After the yellow leather box is placed on the folding box fixing frame 1, the bottom surface of the yellow leather box will be located on the first top plate, and the rear end face and the top surface of the yellow leather box will be arranged on the folding box rotating plate 6. Among them, the lugs on both sides of the rear end face 107 of the yellow leather box will be arranged on a first rotating push block 71 respectively; two rows of first vacuum suction cups 11 are provided on the top of the folding box rotating plate 6, with five groups in each row, which can adsorb and limit the bottom surface of the yellow leather box. At the same time, a non-contact Bernoulli suction cup is installed between the two rows of first vacuum suction cups 11, which allows the yellow leather box to move slightly relative to the folding box rotating plate 6 when folding the top surface 108 of the yellow leather box, so that the folding operation is more smooth.

[0028] In addition, the small ear folding component 73 includes a small ear lifting cylinder 731 and a small ear pressing cylinder 732 mounted at the bottom of the first rotating push block 71; the small ear lifting cylinder 731 and the small ear pressing cylinder 732 are also both drivingly connected to a first folding box push block 733; two first accommodating holes are further formed at the top of the first rotating push block 71, and each first folding box push block 733 is disposed in a first accommodating hole; a first inclined surface whose lower part inclines towards the folding box rotating plate 6 is formed at one side of the first folding box push block 733 close to the folding box rotating plate 6; a number of first vacuum adsorption holes are further formed at the top of the first rotating push block 71.

[0029] The small ear lifting cylinder 731 and the small ear pressing cylinder 732 are sequentially mounted at the bottom of the first rotating push block 71 along the width direction of the folding box rotating plate 6, wherein the small ear lifting cylinder 731 is arranged closer to the folding box rotating plate 6; the first vacuum adsorption holes on the first rotating push block 71 can be connected to an external negative pressure air source, and after the lugs on both sides of the rear end face 107 of the yellow skin box are arranged on the first rotating push block 71, the lugs can be preliminarily adsorbed and limited; subsequently, the small ear lifting cylinder 731 drives the first folding box push block 733 to rise, so as to fold up the small ears on the lugs upwards along the second crease 102 (the first inclined surface is provided to make the folding of the small ears smoother); subsequently, the small ear lifting cylinder 731 descends and resets, and an external manipulator or manual labor places the inner support 109 at the corresponding position of the yellow skin box (on the rear end face 107 of the yellow skin box), wherein first clamping holes are respectively formed at both ends of the inner support 109, and when the inner support 109 is placed, the two small ears folded upwards are respectively inserted and fastened in a first clamping hole; subsequently, the rotation driving cylinder 72 pushes the first rotating push block 71 to rotate upwards through the first push rod 76, so as to fold up the lugs on both sides of the rear end face 107 of the yellow skin box (folded upwards along the third crease 103) and both ends of the inner support 109 upwards, so that they are in a vertical state; subsequently, the small ear pressing cylinder 732 drives the first folding box push block 733 connected thereto to move towards the small ears, so as to press down the small ears to perform pressure holding thereon and ensure the effect of folding upwards.

[0030] In one embodiment, the second folding lug mechanism 8 includes a second connecting block 81, a folding lug lifting cylinder 82, a lug lifting block 83, a first roller 84, and a folding lug pushing block 85. The second connecting block 81 is arranged vertically below the folding box rotating plate 6, and the top of the second connecting block 81 is connected to the bottom of the folding box rotating plate 6. The folding lug lifting cylinder 82 is installed on one side of the second connecting block 81, and the lug lifting block 83 is arranged on one side of the folding box rotating plate 6 and connected to the output shaft of the folding lug lifting cylinder 82. A guiding sliding hole is formed in the top of the lug lifting block 83 along the width direction of the folding box rotating plate 6. The folding lug pushing block 85 has a U-shaped structure, and a guiding block extends downward from the bottom of the U-shaped horizontal end of the folding lug pushing block 85. The guiding block is slidably arranged in the guiding sliding hole, and a first spring 86 is further connected between the side of the guiding block away from the folding box rotating plate 6 and one end of the guiding sliding hole. The first roller 84 is rotatably connected between the two vertical ends of the U-shaped folding lug pushing block 85.

[0031] Continue to refer to Figure 3 and 6 As shown, there are four groups of the second folding lug mechanisms 8, with two groups arranged in the middle of each side of the folding box rotating plate 6. After the top surface of the yellow leather box is arranged on the folding box rotating plate 6, the two lugs on both sides of the top surface 108 of the yellow leather box are respectively arranged corresponding to one second folding lug mechanism 8. After folding up the lugs on both sides of the rear end surface 107 of the yellow leather box, the rotation driving mechanism 5 will drive the folding box rotating plate 6 to rotate towards the direction of the first top plate, so that the yellow leather box is folded up along the fourth crease 104. While folding up, the lugs on both sides of the rear end surface 107 of the yellow leather box will be inserted and buckled into the end buckles of the upwardly folded sides on both sides of the bottom surface 106 of the yellow leather box (with buckles provided at the ends), completing partial buckling. Subsequently, the rotation driving cylinder 72 pushes the first rotation pushing block 71 to rotate downward and reset, and the rotation driving mechanism 5 continues to drive the folding box rotating plate 6 to rotate towards the direction of the first top plate until the rear end surface 107 and the top surface of the yellow leather box are in a vertical state. At this time, the next step is to fold the top surface 108 of the yellow leather box, that is, to fold the top surface 108 of the yellow leather box downward along the fifth crease 105.

[0032] Subsequently, the jacking drive mechanism 3 drives the connected lifting and adjusting plate 4 to drive the folding box rotating plate 6 to rise to a predetermined position, that is, the bottom of the folding box rotating plate 6 is located at the fifth crease 105. Subsequently, the folding box rotating plate 6 adsorbs the top surface 108 of the yellow leather box and continues to rotate in the direction of the first top plate. Due to the existence of the inner support 109, the top surface 108 of the yellow leather box can continue to be folded downward, while the rear end surface 107 of the yellow leather box maintains a vertical state. After rotating a certain angle, the folding lug jacking cylinder 82 drives the lug jacking block 83 to drive the folding lug pushing block 85 to descend, and then the lugs on both sides of the top surface 108 of the yellow leather box are folded downward through the first roller 84 on the folding lug pushing block 85 (a first spring 86 is provided to achieve flexible folding). Subsequently, the folding box rotating plate 6 continues to rotate downward, so that the two lugs on both sides of the top surface 108 of the yellow leather box close to the first top plate direction are first inserted and fastened into the bayonets at the top of the side edges folded upward on both sides of the bottom surface 106 of the yellow leather box (when partially engaged, the two folding lug jacking cylinders 82 close to the first top plate direction are reset). Subsequently, the folding box rotating plate 6 continues to rotate downward, so that the latter two lugs are then inserted and fastened into the bayonets at the top of the side edges on both sides of the bottom surface 106 of the yellow leather box (when partially engaged, the other two folding lug jacking cylinders 82 are reset), completing the folding of the top surface 108 of the yellow leather box. Subsequently, the first vacuum suction cup 11 on the first top plate releases the bottom surface 106 of the yellow leather box, and the folding box rotating plate 6 rotates in the reverse direction to place the folded yellow leather box in a vertical direction for subsequent transfer and blanking.

[0033] In one embodiment, the jacking drive mechanism 3 includes a first connecting frame 31 and a jacking rotating motor 32; the top of the first connecting frame 31 is connected to one end of the bottom of the first top plate, and the jacking rotating motor 32 is installed on the first connecting frame 31; a guiding slide rail module is installed vertically at both ends on one side of the first connecting frame 31. The lifting and adjusting plate 4 is arranged at one end of the folding box fixing frame 1, and one side of the lifting and adjusting plate 4 is slidably connected to the first connecting frame 31 through the guiding slide rail module; the output shaft of the jacking rotating motor 32 is also drivingly connected with a driving gear 33; a first rack 34 is also installed vertically in the middle of one side of the lifting and adjusting plate 4, and the first rack 34 is meshed and connected with the driving gear 33. Driven by the jacking rotating motor 32, the driving gear 33 can be driven to rotate, and then drive the first rack 34 to lift. Since the first rack 34 is installed on one side of the lifting and adjusting plate 4, the lifting and adjusting plate 4 can be driven to perform a lifting motion along the guiding slide rail module.

[0034] Meanwhile, the rotary drive mechanism 5 includes a rotary drive motor 51, a steering box 52, and two second fixed seats 53; both ends of the top of the lifting and adjusting plate 4 are fixedly installed with a second fixed seat 53; the steering box 52 is arranged above the two second fixed seats 53 and is connected to the bottom of the folding box rotary plate 6; each end of the steering box 52 is provided with an output shaft, and each output shaft is connected to a second fixed seat 53; the rotary drive motor 51 is installed at the bottom of the folding box rotary plate 6, and an input shaft is further provided on one side of the steering box 52 facing the rotary drive motor 51, and the input shaft is connected to the output shaft of the rotary drive motor 51. The steering box 52 can adopt a turbine steering box 52. The rotary drive motor 51 and the steering box 52 are both installed at the bottom of the folding box rotary plate 6. When the rotary drive motor 51 operates, it will drive the two output shafts of the steering box 52 to rotate. The output shafts are connected to the second fixed seats 53, and the second fixed seats 53 are fixedly connected to the top of the lifting and adjusting plate 4. Therefore, the second fixed seats 53 will remain stationary, and affected by the reaction force, the steering box 52 will rotate, thereby driving the folding box rotary plate 6 to rotate, so as to fold the yellow leather box.
