[0041] Please see Figure 1 One embodiment of the present invention provides a folding machine, including: a conveying assembly 10, a plurality of folding mechanisms 20 and a plurality of pressure roller assemblies 30;

[0042] The conveying assembly 10 is used to convey products.

[0043] The folding mechanism 20 includes a multi-axis translation drive assembly 210 and a support frame 220. The multi-axis translation drive assembly 210 is driven to the support frame 220 and is used to drive the support frame 220 to rise and fall and move closer to or away from the conveying assembly 10. The support frame 220 is configured to move relative to the conveying assembly 10 to a support position and a folding position under the drive of the multi-axis translation drive assembly 210. When the support frame 220 is in the support position, it is located on one side of the conveying assembly 10 and can support the product together with the conveying assembly 10. When the support frame 220 is in the folding position, at least a portion of the support frame 220 is above the conveying assembly 10. A folding guide 230 is provided on the support frame 220, which is located on the side of the support frame 220 facing the conveying assembly 10 and at the bottom of the support frame 220.

[0044] The pressure roller assembly 30 is vertically and vertically positioned above the conveying assembly 10. When the support frame 220 is in the support position, the pressure roller assembly 30 is located between the conveying assembly 10 and the folding mechanism 20.

[0045] Please see Figures 2 to 5 After the product is conveyed to the appropriate position by the conveyor assembly 10, the first part of the product is on the conveyor assembly 10, and the second part of the product is on the support frame 220. Then, the pressure roller assembly 30 descends and presses on the product. Subsequently, the multi-axis translation drive assembly 210 drives the support frame 220 to rise from the support position. The second part of the product is also driven by the support frame 220 to flip upward. Then, the support frame 220 moves directly above the conveyor assembly 10 until it reaches the folding position. The second part of the product is folded over the first part of the product, realizing the folding of the product. During the process of the support frame 220 moving to the folding position, the folding guide 230 continuously pushes the second part of the product along the first part of the product, so that the second part of the product spreads along the first part of the product. The pressure roller assembly 30 restricts the second part of the product and the first part of the product, so that the first part of the product will not shift its position. The fold line between the first part of the product and the second part of the product forms a stable position. Moreover, the second part of the product is also pressed tightly onto the first part of the product by the folding guide 230, so that the product achieves stable folding and good folding effect.

[0046] The specific structure of the multi-axis translation drive assembly 210 can be selected according to actual needs. For example, the multi-axis translation drive assembly 210 includes a lifting drive module 211 and a horizontal drive module 212. The horizontal drive module 212 is driven to the lifting drive module 211, and the lifting drive module 211 is driven to the support frame 220. The horizontal drive module 212 drives the lifting drive module 211 and the support frame 220 to move closer to or further away from the conveying assembly 10, and the lifting drive module 211 drives the support frame 220 to rise and fall. The lifting drive module 211 and the horizontal drive module 212 can be screw drive modules, rotary motor translation drive modules, belt translation drive modules, cylinder translation drive modules, or linear motor translation drive modules, etc., and are not limited to this example.

[0047] Please see Figure 6 In some optional embodiments, the folding guide 230 includes a side push plate 231 disposed on one side of the support frame 220 and a pressure plate 232 disposed at the bottom of the support frame 220. The side push plate 231 is connected to the pressure plate 232. When the support frame 220 moves to the folding position, the side push plate 231 pushes the second part of the product, so that the second part of the product gradually unfolds on the first part of the product, while the pressure plate 232 presses the second part of the product onto the first part of the product, thereby achieving a better folding effect.

[0048] In some alternative embodiments, the folding guide 230 also includes an inclined guide plate 233, which is connected to the side push plate 231 and the pressure plate 232 respectively. The inclined guide plate 233 extends downward at an angle from the side push plate 231 to the pressure plate 232. The inclined guide plate 233 can better guide the second part of the product to unfold onto the first part of the product, making the product fold more smoothly.

[0049] In some alternative embodiments, a clearance gap 240 is formed between the pressure plate 232 and the bottom of the support frame 220. The pressure plate 232 and / or the side push plate 231 and / or the inclined guide plate 233 are elastic. When the pressure plate 232 presses against the product, the pressure plate 232 and / or the side push plate 231 and / or the inclined guide plate 233 undergo elastic deformation to allow the pressure plate 232 to move toward the bottom of the support frame 220. In this embodiment, the pressure plate 232, the side push plate 231, and the inclined guide plate 233 are integrally formed and are all elastic metal plates. When the pressure plate 232 presses the second part of the product onto the first part of the product, the elastic deformation of the pressure plate 232 and / or the side push plate 231 and / or the inclined guide plate 233 can prevent the pressure plate 232 from making hard contact with the product, thereby avoiding damage to the product.

[0050] With only a single folding mechanism 20 and pressure roller assembly 30, a two-fold product can be achieved. In some optional embodiments, the folding machine includes two folding mechanisms 20 and two pressure roller assemblies 30. When the support frames 220 of the two folding mechanisms 20 are in the supported position, the support frames 220 of the two folding mechanisms 20 are respectively arranged on both sides of the conveying assembly 10, and the pressure roller assemblies 30 are correspondingly arranged between the side of the conveying assembly 10 and the folding mechanism 20. The two folding mechanisms 20 and the two pressure roller assemblies 30 can achieve two-fold and three-fold products as needed; please refer to [link to relevant documentation]. Figure 7 When it is necessary to achieve a three-fold fold of the product, the first part of the product is on the conveying assembly 10, the second part of the product is on the support frame 220 of one of the folding mechanisms 20, and the third part of the product is on the support frame 220 of another folding mechanism 20. The second part of the product is folded onto the first part of the product, and then the third part of the product is folded onto the second part of the product, thereby achieving a three-fold fold of the product.

[0051] In some optional embodiments, the support frame 220 is provided with a plurality of auxiliary conveying modules 221. When the support frame 220 is in the supporting position, the auxiliary conveying modules 221 and the conveying components 10 can jointly support the product. Before the product is folded, the auxiliary conveying modules 221 and the conveying components 10 can cooperate to convey the product, so that the product as a whole can be subjected to appropriate conveying force and realize the stable conveying of the product to the appropriate position for folding.

[0052] The specific structure of the auxiliary conveying module 221 and the conveying component 10 can be selected according to actual needs. For example, the auxiliary conveying module 221 and the conveying component 10 can adopt a mesh belt conveyor, a roller conveyor, a chain conveyor, or a belt conveyor, etc. The specific selection can be made according to the needs of the product, and this example is not limited.

[0053] The specific structure of the support frame 220 can be selected according to actual needs. For example, in some optional embodiments, the support frame 220 includes a fixed frame 222 and an extension frame 223. The extension frame 223 is disposed on the top of the fixed frame 222 and extends from the side of the fixed frame 222 close to the fixed frame 222. The folding guide 230 is disposed on the side of the extension frame 223 facing the conveying assembly 10 and at the bottom of the extension frame 223. The multi-axis translation drive assembly 210 is drivenly connected to the fixed frame 222. When the support frame 220 is in the supporting position, the fixed frame 222 and / or the extension frame 223 and the conveying assembly 10 can support the product together. When the support frame 220 is in the folded position, the extension frame 223 is above the conveying assembly 10, while the fixed frame 222 is on one side of the conveying assembly 10.

[0054] Please see Figure 8In some alternative embodiments, the pressure roller assembly 30 includes: a first lifting seat 310, a second lifting seat 320, and a pressure roller 340;

[0055] The first lifting seat 310 is raised and lowered under the drive of the first lifting mechanism 311;

[0056] The second lifting seat 320 is lifted and lowered under the drive of the second lifting mechanism 321. A clearance space 330 for avoiding materials is formed between the first lifting seat 310 and the second lifting seat 320. The first lifting seat 310 and the second lifting seat 320 are arranged sequentially along the conveying direction of the conveying assembly 10.

[0057] The pressure roller 340 is disposed on the first lifting seat 310 and extends along the conveying direction of the conveying assembly 10. When the support frame 220 is in the supporting position, the pressure roller 340 is located between the conveying assembly 10 and the support frame 220. The second lifting seat 320 is provided with a pressing part 322 located above the pressure roller 340. When the first lifting mechanism 311 drives the first lifting seat 310 to descend so that the pressure roller 340 descends to the pressing position, the second lifting seat 320 descends under the drive of the second lifting mechanism 321 so that the pressing part 322 presses against the top of the pressure roller 340.

[0058] Before folding the product, the conveying assembly 10 conveys the product between the first lifting seat 310 and the second lifting seat 320. Then, the first lifting mechanism 311 drives the first lifting seat 310 to descend, so that the pressure roller 340 presses against the product. Then, the second lifting mechanism 321 drives the second lifting seat 320 to press down, so that the pressing part 322 of the second lifting seat 320 presses against the pressure roller 340. This allows the pressure roller 340 to be subjected to force on both sides of the clearance space 330, so that the pressure roller 340 can stably press the product during the folding process and is not easy to shift its position, thus improving the folding quality of the product. After the product is folded, the second lifting seat 320 rises, so that the pressing part 322 disengages from the pressure roller 340. Then, the conveying assembly 10 can carry the product away. During the product's departure, the product can move along the pressure roller 340 and then disengage from the end of the pressure roller 340 away from the first lifting seat 310, thus separating the product from the pressure roller 340.

[0059] In some alternative embodiments, the pressing part 322 is a positioning groove. When the positioning groove presses against the pressure roller 340, the positioning groove and the pressure roller 340 are positioned and engaged. The pressure roller 340 extends into the positioning groove and is positioned by the positioning groove, thereby preventing the pressure roller 340 from shifting left and right relative to the second lifting seat 320 during the folding process.

[0060] In some alternative embodiments, the shape of the positioning groove matches the shape of the pressure roller 340, which is typically cylindrical, while the positioning groove matches the surface of the pressure roller 340 in an arc shape, thereby enabling stable positioning of the pressure roller 340 and reducing friction between them.

[0061] Please see Figure 9 To facilitate stable fixing of the pressure roller 340, in some optional embodiments, two lifting fixing plates 312 are detachably mounted on the first lifting seat 310, arranged sequentially along the axis of the pressure roller 340. The lifting fixing plates 312 have mounting holes 313, through which the pressure roller 340 passes. The two lifting fixing plates 312 can jointly constrain the pressure roller 340, preventing it from deflecting relative to the first lifting seat 310 during folding, improving the coaxiality of the pressure roller 340 relative to the mounting holes 313, and thus improving the accuracy of the fold line position on the product. Furthermore, the lifting fixing plates 312 are detachable, facilitating the replacement of different types of pressure rollers 340 to adapt to different products. In this embodiment, the lifting fixing plates 312 are detachably engaged with the first lifting seat 310 via screws or other structures, but this is not a limitation.

[0062] To improve the stability of the mounting roller 340, in some optional embodiments, a fixing sleeve 314 extending along the axis of the roller 340 is provided in the mounting hole 313. The roller 340 passes through the fixing sleeve 314 to realize that the roller 340 passes through the mounting hole 313. The mounting hole 313 is further extended in the axial direction to contact the roller 340 through the fixing sleeve 314, thereby stably restricting the roller 340 in the axial direction and preventing the roller 340 from deflecting.

[0063] In some alternative embodiments, a side pressure plate 323 is detachably provided on one side of the second lifting seat 320, and a pressing part 322 is provided at the bottom of the side pressure plate 323. The side pressure plate 323 is detachable, which facilitates the replacement of pressing parts 322 of different shapes, thereby adapting to different types of pressure rollers 340. In this embodiment, the side pressure plate 323 is detachably engaged with the second lifting seat 320 by means of screws or other structures, but this is not a limitation.

[0064] Please see Figure 10 and Figure 11 In some optional embodiments, the first lifting mechanism 311 includes a first lifting drive motor 315, a first lifting drive gear 316, and a first lifting drive rack 317. The first lifting drive motor 315 is mounted on the first lifting seat 310 and is drivenly connected to the first lifting drive gear 316. The first lifting drive rack 317 is located on one side of the first lifting drive gear 316 and meshes with it; and / or,

[0065] The second lifting mechanism 321 includes a second lifting drive motor 324, a second lifting drive gear 325, and a second lifting drive rack 326. The second lifting drive motor 324 is mounted on the second lifting seat 320 and is drivenly connected to the second lifting drive gear 325. The second lifting drive rack 326 is mounted on one side of the second lifting drive gear 325 and meshes with the second lifting drive gear 325.

[0066] In this embodiment, the first lifting mechanism 311 includes a first lifting drive motor 315, a first lifting drive gear 316, and a first lifting drive rack 317, and the second lifting mechanism 321 includes a second lifting drive motor 324, a second lifting drive gear 325, and a second lifting drive rack 326. Of course, the first lifting mechanism 311 and the second lifting mechanism 321 can also adopt other suitable lifting mechanisms, such as a screw lifting mechanism, a rotary motor translation lifting mechanism, a belt translation lifting mechanism, a cylinder translation lifting mechanism, or a linear motor translation lifting mechanism, without being limited to this example.

[0067] The first lifting drive motor 315 drives the first lifting drive gear 316 to rotate, thereby causing the first lifting drive gear 316 to move along the first lifting drive rack 317, which in turn drives the first lifting seat 310 to rise and fall along the first lifting drive rack 317; the second lifting drive motor 324 drives the second lifting drive gear 325 to rotate, thereby causing the second lifting drive gear 325 to move along the second lifting drive rack 326, which in turn drives the second lifting seat 320 to rise and fall along the second lifting drive rack 326.

[0068] In some optional embodiments, the pressure roller assembly 30 further includes a movable frame 360 ​​and a position adjustment assembly 350. The position adjustment assembly 350 is drivenly connected to the movable frame 360 ​​and is used to drive the movable frame 360 ​​to move in a direction closer to or farther from the conveying assembly 10. A first lifting mechanism 311 and a second lifting mechanism 321 are disposed on the movable frame 360. The position adjustment assembly 350 adjusts the position of the movable frame 360 ​​relative to the conveying assembly 10, thereby synchronously adjusting the positions of the first lifting mechanism 311 and the second lifting mechanism 321, and thus adjusting the position of the pressure roller 340, so that the pressure roller 340 can move to a suitable position according to the fold line position requirements of the product. In this embodiment, both the first lifting drive rack 317 and the second lifting drive rack 326 are fixed on the movable frame 360.

[0069] In this embodiment, the folding machine also includes a frame 40, on which the conveying assembly 10, the folding mechanism 20 and the movable frame 360 ​​are all mounted.

[0070] The specific structure of the position adjustment assembly 350 can be selected according to actual needs. For example, in some optional embodiments, the position adjustment assembly 350 includes a position adjustment motor 351, a transmission screw 352, two position adjustment gears 353, and two position adjustment racks 354. The position adjustment motor 351 and the transmission screw 352 are mounted on the movable frame 360. The position adjustment motor 351 is drivenly connected to the transmission screw 352. The position adjustment gears 353 are mounted on the transmission screw 352. The two position adjustment racks 354 can be fixed on the frame 40 and are correspondingly arranged on both sides of the clearance space 330. The position adjustment gears 353 and the position adjustment... The rack 354 engages, and the position adjustment motor 351 drives the transmission screw 352 to rotate, which in turn drives the two position adjustment gears 353 to rotate synchronously. The two position adjustment gears 353 move along the two position adjustment racks 354, thereby driving the movable frame 360 ​​to move. Since the product size is usually relatively large, the clearance space 330 between the first lifting seat 310 and the second lifting seat 320 is also relatively long. Therefore, the two position adjustment racks 354 are positioned on both sides of the clearance space 330 to cooperate with the position adjustment gears 353, thereby improving the stability of the movement of the movable frame 360 ​​and preventing the movable frame 360 ​​from deflecting, which would cause the pressure roller 340 to deflect.

[0071] When the folding machine includes two pressure roller assemblies 30, the pressure rollers 340 of the two pressure roller assemblies 30 can be moved closer to or further apart from each other by a position adjustment assembly 350. The position adjustment racks 354 of the two position adjustment assemblies 350 are preferably integrally formed or connected to each other, thereby improving assembly stability.
