In the following detailed description of the present application, some specific details are described in order to provide a thorough understanding of the present application. The present application can be fully understood without these details. In order to avoid obscuring the essence of the present application, well-known methods, procedures, processes, elements and circuits are not described in detail.

[0047] In addition, it should be understood by those of ordinary skill in the art that the drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0048] Unless specifically stated otherwise, the terms "mounting", "connected", "connecting", "fixed", "fixedly connected", "connection", "joint", "jointly connected", "connecting" and the like are used broadly and encompass both direct and indirect mounting, connecting, or connecting and are not limited to physical or mechanical connections or connections of other means. It is also to be understood that the terms "connected" and "connection" can refer, but do not necessarily refer, to an electrical connection, to electrical charge, or to a magnetic connection.

[0049] For ease of description, spatially relative terms such as "inner", "outer", "beneath", "below", "lower", "above", "upper", and the like, can be used herein for the purpose of illustrating one element or feature's relationship to another element or feature within a figure. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device is inverted, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0050] Unless the context clearly requires otherwise, throughout the description, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

[0051] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various elements, but are not necessarily used to describe, and do not necessarily imply, a relative importance or a given order of elements.

Figure 2 is a variation process schematic diagram of material folding through the folding device provided by an embodiment of the present application, as shown in Figure 2As shown, the material 6 is sequentially subjected to the automatic operations of the feeding module 2, the preliminary folding module 3, the buckling module 4 and the top bending module 5, and finally is folded into the required cushion. Among them, the feeding module 2 is used to push the material 6 to move relative to the workbench 1, the preliminary folding module 3 is used to preliminarily bend the material 6, the buckling module 4 is used to complete buckling, and finally the top bending module 5 is used to top bend and form. Specifically, the preliminary folding module 3 first bends two side edges of the material 6 to form a base 61 and a first fold edge 62 and a second fold edge 63 connected to the base 61, respectively, and then bends the first fold edge 62 to form a first support portion 621 connected to the base 61 and a matching portion 622 connected to the first support portion 621, while bending a fold ear 64 on the second fold edge 63. Among them, the connection between the first support portion 621 and the matching portion 622 has a clamping groove 65. Further, the buckling module 4 bends the second fold edge 63 to form a second support portion 631 connected to the base 61 and a buckling portion 632 connected to the second support portion 631. Further, the fold ear 64 is located on the buckling portion 632, and the buckling module 4 bends the buckling portion 632 and inserts the fold ear 64 into the clamping groove 65. Finally, the top bending module 5 synchronously bends the first support portion 621 and the second support portion 631 to bend the first support portion 621 and the second support portion 631 into a V-shaped inwardly concave shape. Optionally, the material 6 is provided with a preliminary folding line. Thus, the folding device realizes the automatic folding of the material into a cushion, which helps to reduce labor costs and improve production efficiency.

[0053] Figure 3 is a structural schematic diagram of the feeding module provided by the embodiment of the present application, as Figure 3 As shown, in some embodiments, the feeding module 2 includes a feeding mechanism 21 and a guide mechanism 22. Specifically, the feeding mechanism 21 pushes the material 6 to move relative to the workbench 1, and the guide mechanism 22 is connected with the feeding mechanism 21 to provide support, guidance and limiting effect. It should be noted that after the feeding module 2 delivers the material 6 to the preliminary folding module 3 for preliminary folding operation, the next material 6 can be directly put in, and the different forms of the material 6 in the feeding module 2, the preliminary folding module 3, the buckling module 4 and the top bending module 5 are in a sequentially abutting state, so that one feeding module 2 can synchronously drive the overall movement of the materials 6 in multiple forms, which helps to simplify the structure of the feeding module 2 and reduce the cost.

[0054] As Figure 3As shown, in some embodiments, the feeding mechanism 21 comprises a feeding push block 211 and a feeding driving member 212 connected with the feeding push block 211. Specifically, the feeding driving member 212 is fixed on the workbench 1 along the horizontal direction and drives the feeding push block 211 to push the material 6. It should be noted that there are multiple feeding push blocks 211, which are synchronously driven by the feeding driving member 212, so that the flat material 6 can be pushed from multiple positions at the same time to ensure the stability of the movement. Optionally, the feeding driving member 212 is a pneumatic cylinder. Further, the guiding mechanism 22 comprises a sliding rail 221 and a sliding block 222. Specifically, the sliding rail 221 is arranged on the workbench 1, and the sliding block 222 is slidingly arranged on the sliding rail 221 and connected with the feeding push block 211. Thus, the guiding mechanism 22 can support, guide and limit the feeding mechanism 21.

[0055] Figure 4 is a structural schematic diagram of a pre-folding mold provided by an embodiment of the present application, as shown in Figure 4 As shown, in some embodiments, the pre-folding mold 3 comprises a first pre-folding mechanism 31, a second pre-folding mechanism 32, a third pre-folding mechanism 33 and a fourth pre-folding mechanism 34. Specifically, the first pre-folding mechanism 31 first bends the first side edge of the material 6 to form a first folded edge 62, while the second pre-folding mechanism 32 bends the second side edge of the material 6 to form a second folded edge 63. Further, the third pre-folding mechanism 33 bends the first folded edge 62 to form a first supporting part 621 and a matching part 622, while the fourth pre-folding mechanism 34 bends the folded ear 64. Thus, the pre-folding mold 3 realizes the pre-folding operation of the material 6 through two groups of bending actions.

[0056] Figure 5 is a structural schematic diagram of a first pre-folding mechanism provided by an embodiment of the present application, as shown in Figure 5 As shown, in some embodiments, the first pre-folding mechanism 31 comprises a first roller 311 and a first pre-folding driving member 312 connected with the first roller 311. Specifically, the first pre-folding driving member 312 is fixed on the workbench 1 along the vertical direction and drives the first roller 311 to bend the material 6 and form the first folded edge 62.

Specifically, the second pre-folding driving member 322 is fixed on the workbench 1 in the vertical direction and drives the second roller 321 to bend the material 6 to form the second fold edge 63. It should be noted that the first pre-folding mechanism 31 and the second pre-folding mechanism 32 need to bend the material 6 by 90 degrees respectively, and by arranging the first roller 311 and the second roller 321 to directly contact the material 6, damage to the material 6 can be avoided. Optionally, the lengths of the first roller 311 and the second roller 321 are matched with the material 6. Optionally, the first pre-folding driving member 312 and the second pre-folding driving member 322 are arranged as air cylinders, and drive the first roller 311 and the second roller 321 vertically upward from the bottom of the workbench 1 respectively, so as to bend the material 6 to form the vertical first fold edge 62 and the second fold edge 63.

[0057] Figure 7 is a structural schematic diagram of a third pre-folding mechanism provided by an embodiment of the present application, as shown in Figure 7 In some embodiments, the third pre-folding mechanism 33 comprises a first pre-folding push block 331, a third pre-folding driving member 332 connected with the first pre-folding push block 331, and a fifth pre-folding driving member 333 connected with the third pre-folding driving member 332. Specifically, the fifth pre-folding driving member 333 is fixed on the workbench 1 in the vertical direction and drives the third pre-folding driving member 332 to move towards the first fold edge 62, the third pre-folding driving member 332 is arranged obliquely downward and drives the first pre-folding push block 331 to bend the first fold edge 62 to form the first supporting part 621 and the fitting part 622. Correspondingly, Figure 8 is a structural schematic diagram of a fourth pre-folding mechanism provided by an embodiment of the present application, as shown in Figure 8 The fourth pre-folding mechanism 34 comprises a second pre-folding push block 341, a fourth pre-folding driving member 342 connected with the second pre-folding push block 341, and a sixth pre-folding driving member 343 connected with the fourth pre-folding driving member 342. Specifically, the sixth pre-folding driving member 343 is fixed on the workbench 1 in the vertical direction and drives the fourth pre-folding driving member 342 to move towards the second fold edge 63, the fourth pre-folding driving member 342 is arranged obliquely downward and drives the second pre-folding push block 341 to bend the fold ear 64. Exemplarily, the fitting part 622 is bent by 90 degrees relative to the first supporting part 621, and the fold ear 64 is bent by 60 degrees relative to the second fold edge 53. Optionally, the top of the first pre-folding push block 331 and the second pre-folding push block 341 is formed with a curved surface to avoid damage when contacting the first fold edge 62 and the fold ear 64. Optionally, the third pre-folding driving member 332, the fourth pre-folding driving member 342, the fifth pre-folding driving member 333 and the sixth pre-folding driving member 343 are arranged as air cylinders. It should be noted that there are two fold ears 64, and the fourth pre-folding mechanism 34 is provided with two and is distributed in intervals to correspond to the fold ears 64 one by one.

[0058] AsFigure 4 As shown, in some embodiments, the pre-folding module 3 further includes a first retaining mechanism 35 and a second retaining mechanism 36. Specifically, the first retaining mechanism 35 blocks the first folded edge 62 from one side to keep the first folded edge 62 bent, and the second retaining mechanism 36 blocks the second folded edge 63 from one side to keep the second folded edge 63 bent. Thus, the pre-folding module 3 can prevent the first folded edge 62 and the second folded edge 63 from springing back by providing the first retaining mechanism 35 and the second retaining mechanism 36. It should be noted that after the first pre-folding mechanism 31 acts to form the first folded edge 62, the first retaining mechanism 35 blocks the first folded edge 62 from one side, and then the third pre-folding mechanism 33 bends the first folded edge 62. Correspondingly, after the second pre-folding mechanism 32 acts to form the second folded edge 63, the second retaining mechanism 36 blocks the second folded edge 63 from one side, and then the fourth pre-folding mechanism 34 bends the folded ear 64.

[0059] Figure 9 This is a schematic diagram of the structure of the first retaining mechanism provided in an embodiment of the present invention, as shown below. Figure 9 As shown, in some embodiments, the first retaining mechanism 35 includes a first retaining member 351 and a first retaining drive member 352 connected to the first retaining member 351. Specifically, the first retaining drive member 352 is arranged vertically and drives the first retaining member 351 to move to one side of the first folded edge 62. Correspondingly, Figure 10 This is a schematic diagram of the structure of the second retaining mechanism provided in an embodiment of the present invention, as shown below. Figure 10 As shown, the second holding mechanism 36 includes a second holding member 361 and a second holding drive member 362 connected to the second holding member 361. Specifically, the second holding drive member 362 is arranged vertically and drives the second holding member 361 to move to one side of the second folded edge 63. It should be noted that the first holding member 351 is generally plate-shaped, and its bottom is inclined away from the first folded edge 62 to prevent damage caused by touching the first folded edge 62 during descent. Correspondingly, the second holding member 361 is generally plate-shaped, and its bottom is inclined away from the second folded edge 63 to prevent damage caused by touching the second folded edge 63 during descent. It should be further noted that there are two first pre-folding push blocks 331, which are spaced apart, ensuring both the bending effect on the first folded edge 62 and avoiding contact with the first holding member 351. Optionally, the first holding drive member 352 and the second holding drive member 362 are configured as cylinders.

[0060] like Figure 4 As shown, in some embodiments, the pre-folding module 3 further includes a pre-folding contour block 37. Specifically, the pre-folding contour block 37 is hung on a bracket provided on the worktable 1, thereby achieving a spaced arrangement between the pre-folding contour block 37 and the worktable 1, so that the material 6 can be located between the pre-folding contour block 37 and the worktable 1. Further, Figure 11is a structural schematic view of a pre-folding profiling block and a buckling profiling block provided by an embodiment of the present application, Figure 12 is a structural schematic view of another perspective of the pre-folding profiling block and the buckling profiling block provided by an embodiment of the present application, in combination with Figure 11 and 12 As shown in the figure, the pre-folding profiling block 37 has a first pre-folding profiling surface 371, a second pre-folding profiling surface 372, and a third pre-folding profiling surface 373. It is easy to understand that the first pre-folding profiling surface 371 matches the base 61, the second pre-folding profiling surface 372 matches the first supporting part 621, and the third pre-folding profiling surface 373 matches the second folding edge 63.
