[0036] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings.

Therefore, it will be understood that "upper" and "lower" are used interchangeably. It will be understood that when a layer is referred to as being "on" another layer, it can be directly formed on the other layer, or intervening layers may also be present. Therefore, it will be understood that when a layer is referred to as being "directly on" another layer, there are no intervening layers therebetween.

[0039] In the drawings, the dimensions of layers and regions may be exaggerated for clarity. It will be understood that when a layer or element is referred to as being "on" another layer or substrate, the layer or element may be directly on the other layer or substrate, or intervening layers may be present. Additionally, it will be understood that when a layer is referred to as being "between" two layers, the layer may be the only layer between the two layers, or one or more intervening layers may be present. Like reference numerals refer to like elements throughout.

[0040] Hereinafter, although terms such as "first," "second," and the like may be used to describe various components, these components are not limited to the above terms.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0043] See also Figures 1 to 6 The present application provides a conveying device 100, which includes a frame 10, a first conveying unit 20, and a second conveying unit 30. The first conveying unit 20 is mounted on the frame 10, and the frame 10 provides stable support for the first conveying unit 20. The first conveying unit 20 includes a plurality of first conveying mechanisms 21 spaced apart along a first direction, each of which is used to convey materials along a second direction. Furthermore, the second conveying unit 30 is mounted on the frame 10, and the frame 10 provides stable support for the second conveying unit 30. The second conveying unit 30 includes a plurality of second conveying mechanisms 31 spaced apart along the first direction, each of which is used to convey materials along the first direction. The provision of the first conveying unit 20 and the second conveying unit 30 facilitates material conveyance in different directions.

[0044] like Figure 1 and Figure 3As shown, further, a first conveying mechanism 21 is provided between any two adjacent second conveying mechanisms 31; wherein, at least one of the first conveying unit 20 and the second conveying unit 30 can be raised and lowered in the vertical direction. This facilitates the transfer and transportation of materials between the first conveying unit 20 and the second conveying unit 30 through vertical lifting. Exemplarily, the first conveying mechanism 21 in the first conveying unit 20 conveys materials in the second direction, and the height of the first conveying mechanism 21 is higher than that of the second conveying mechanism 31. In this case, the second conveying mechanism 31 moves upward in the vertical direction, or the first conveying mechanism 21 moves downward in the vertical direction so that the second conveying mechanism 31 is higher than the first conveying mechanism 21, thereby transferring materials from the first conveying mechanism 21 to the second conveying mechanism 31. The second conveying mechanism 31 then transports the materials in the first direction, thereby achieving reversible conveying.

[0045] Furthermore, at least a portion of the first conveying mechanism 21 and / or at least a portion of the second conveying mechanism 31 is capable of moving in the first direction. Thus, by adjusting the distance between any two adjacent first conveying mechanisms 21 and second conveying mechanisms 31 through movement, the spacing between the first conveying mechanism 21 and second conveying mechanism 31 can be adjusted to suit the size of the conveyed material, thereby reducing edge deformation and material dropout, particularly for small and flexible materials. Specifically, when conveying small materials, reducing the spacing between adjacent first conveying mechanisms 21 and second conveying mechanisms 31 can prevent small materials from falling through the gap between the first and second conveying mechanisms 21 and 31 during direction reversal. When conveying flexible materials, which tend to sag, adjusting the spacing between adjacent first and second conveying mechanisms 21 and 31 to bring them closer together facilitates effective support of the flexible material during direction reversal, preventing the flexible material from sag or dropout from the gap between the first and second conveying mechanisms 21 and 31 during direction reversal.

[0046] In summary, by adjusting the distance between the adjacent first conveying mechanism 21 and the second conveying mechanism 31, the small-sized materials and flexible materials that fall from the gap between the first conveying mechanism 21 and the second conveying mechanism 31 during the reversing conveying can be greatly reduced, thereby ensuring the stability of the material state during the reversing conveying, and the distance can be finely adjusted according to actual needs.

[0047] For ease of description, the first direction and the second direction are perpendicularly arranged, and the first direction is the x-axis, the second direction is the y-axis, and the vertical direction, which is the height direction of the rack 10, is described as the z-axis.

[0048] like Figure 1 and Figure 3As shown, in an optional embodiment, the first conveying unit 20 and / or the second conveying unit 30 further include a guide rail and a locking structure, wherein the guide rail is mounted on the frame 10, and the frame 10 provides support for the guide rail. At least part of the first conveying mechanism 21 and / or at least part of the second conveying mechanism 31 is slidably connected to the respective corresponding guide rails, so that the first conveying mechanism 21 and / or the second conveying mechanism 31 can move smoothly, reduce movement resistance, and promote rapid adjustment of the distance between adjacent first conveying mechanisms 21 and second conveying mechanisms 31. The locking structure is used to lock the corresponding first conveying mechanism 21 or second conveying mechanism 31 to the corresponding guide rail to achieve fixation of the first conveying mechanism 21 or second conveying mechanism 31 after movement, thereby ensuring stable transportation of materials.

[0049] like Figure 1 and Figure 3 As shown, in a further embodiment, the guide rail is divided into a first guide rail 22 and a second guide rail 32, and the locking structure is divided into a first locking structure and a second locking structure; the first conveying unit 20 includes a first guide rail 22 and a first locking structure, and the second conveying unit 30 includes a second guide rail 32 and a second locking structure.

[0050] like Figure 3 As shown, in a further embodiment, the first conveying unit 20 further includes a slider 23, which is slidably connected between the first guide rail 22 and the first conveying mechanism 21. The slider 23 cooperates with the first guide rail 22 to form a guiding function for the movement of the first conveying mechanism 21, thereby improving the smoothness of the movement of the first conveying mechanism 21. The first locking structure is used to lock the slider 23 relative to the first guide rail 22, which is easy to operate.

[0051] In a further embodiment, the slider 23 includes a sliding portion and a locking portion spaced apart along the length of the first guide rail 22. The sliding portion is slidably connected to the first guide rail 22, and the first locking structure is connected to the first guide rail 22 through the locking portion. In this arrangement, the slider 23 integrates the sliding portion and the locking portion to simultaneously perform the sliding and locking functions. The sliding portion and the locking portion are spaced apart to avoid interference with each other.

[0052] In a further embodiment, the locking portion is constructed with a first locking hole, the first locking structure is passed through the first locking hole, and can move axially along the first locking hole to lock or unlock with the first guide rail 22. When the first locking structure moves to be pressed against the first guide rail 22, it can increase the friction of the movement of the slider 23, thereby limiting the movement of the slider 23 relative to the first guide rail 22, thereby achieving the locking of the slider 23 relative to the first guide rail 22.

[0053] More specifically, the first locking structure is threadedly connected to the wall of the first locking hole. By screwing the first locking structure, the first locking structure can reciprocate within the first locking hole, thereby controlling the locking assembly of the first locking structure to the first guide rail 22. When the first locking structure rotates in the forward direction, the first locking structure moves toward the first guide rail 22 until it completely presses the first guide rail 22 to lock the movement of the slider 23 relative to the first guide rail 22. When the first locking structure rotates in the reverse direction, the first locking structure moves away from the first guide rail 22 to cancel the lock on the movement of the slider 23 relative to the first guide rail 22. Furthermore, the first locking structure is also provided with a screwing handle to facilitate manual operation.

[0054] In a specific embodiment, the first guide rail 22 is provided with a sliding groove whose width gradually expands outward along its depth direction to form an inclined groove wall. The end of the first locking structure is configured to taper toward the sliding groove to form an inclined surface, allowing the first locking structure to fit tightly against the sliding groove wall. This configuration increases the mating area between the first locking structure and the sliding groove, enhancing the first locking structure's pressing effect on the sliding groove wall.

[0055] like Figure 1 and Figure 3 As shown, in a further embodiment, the second conveying unit 30 further includes a sliding bracket 33, which is connected to the second conveying mechanism 31 and slidably connected to the second guide rail 32. The sliding bracket 33 can move along the extension direction of the second guide rail 32 to drive the movement of the second conveying mechanism 31. Furthermore, the sliding bracket 33 is configured with a second locking hole, and a second locking structure is provided in the second locking hole and connected to the second guide rail 32 to lock the sliding bracket 33 to the second guide rail 32.

[0056] like Figure 1 and Figure 3 As shown, in an optional embodiment, the conveying device 100 further includes a distance adjustment mechanism 40; one of the first conveying mechanism 21 and the second conveying mechanism 31 is connected to the distance adjustment mechanism 40, and moves along the first direction under the action of the corresponding distance adjustment mechanism 40. Exemplarily, the first conveying mechanism 21 is connected to the distance adjustment mechanism 40, and the distance between the second conveying mechanism 31 is manually adjusted; alternatively, the second conveying mechanism 31 is connected to the distance adjustment mechanism 40, and the distance between the first conveying mechanism 21 is manually adjusted.

[0057] like Figure 1 、 Figure 2 and Figure 5As shown, in a further embodiment, the distance adjusting mechanism 40 includes a plurality of connecting shafts 41, any two adjacent connecting shafts 41 are spliced, at least some of the connecting shafts 41 are connected to the first conveying mechanism 21 or the second conveying mechanism 31, and the connecting shafts 41 support the first conveying mechanism 21 and / or the second conveying mechanism 31; wherein, at least one of any two adjacent connecting shafts 41 can move along the first direction to drive the corresponding first conveying mechanism 21 or the second conveying mechanism 31 to move synchronously, and the operation is simple.

[0058] like Figure 5 As shown, in a specific embodiment, one of any two adjacent connecting shafts 41 is provided with a telescopic channel 411, and the other is inserted into the telescopic channel 411 and can reciprocate within the telescopic channel 411 along the axial direction of the connecting shaft 41 to achieve a telescopic function, thereby adjusting the distance between any adjacent first conveying mechanism 21 and second conveying mechanism 31. The provision of the telescopic channel 411 guides the movement of adjacent connecting shafts 41, reduces external space occupation, and improves aesthetics.

[0059] In another specific embodiment, among any two adjacent connecting shafts 41, one of them is provided with a sliding channel extending axially along the connecting shaft 41 on the outer peripheral surface, and the other is slidingly connected to the sliding channel, which is conducive to smooth extension and retraction, and enables the operator to intuitively feel the extension and retraction length of the two connecting shafts 41, facilitating timely adjustment.

[0060] In an optional embodiment, the distance adjustment mechanism 40 also includes a locking structure 42, and at least some of any two adjacent connecting shafts 41 are detachably connected with a locking structure 42, and are locked by the corresponding locking structure 42, so that the two adjacent connecting shafts 41 can be locked and fixed after the telescopic length is adjusted, so that the position of the first conveying mechanism 21 or the second conveying mechanism 31 is fixed, thereby promoting smooth operation.

[0061] like Figure 2 As shown, in an optional embodiment, the locking structure 42 includes a sleeve 421 and a locking member. The sleeve 421 is positioned between at least a portion of any two adjacent connecting shafts 41. The locking member passes through the corresponding sleeve 421 and one of the two adjacent connecting shafts 41 to connect to the other. The locking member locks the sleeve 421 and any two adjacent connecting shafts 41, simplifying operation. The sleeve 421 provides guidance and support for the locking member, thereby enhancing the connection strength of the locking member and facilitating torque transmission between any two adjacent connecting shafts 41.

[0062] In another embodiment, the locking structure 42 includes a locking member. Among any two adjacent connecting shafts 41 , the locking member passes through one of them to be connected to the other one, which is more direct and simple.

[0063] like Figure 2 As shown, in a specific embodiment, of any two adjacent connecting shafts 41, the locking member passes through one of them, and the other is provided with an abutment surface 412 on its outer circumference. The locking member is pressed against the abutment surface 412 to increase the area of ​​engagement with the locking member, increase friction, and promote the locking member to be pressed against the first connecting shaft 41. The abutment surface 412 can be formed by milling.

[0064] like Figure 2 As shown, in a specific embodiment, the sleeve 421 is configured with a first assembly hole 4211. Of any two adjacent connecting shafts 41, one has a second assembly hole 413. A locking member passes through the first and second assembly holes 4211, 413, and is pressed against the outer wall of the other. At least one of the first and second assembly holes 4211, 413, is threadedly connected to the locking member. Thus, both the second and first assembly holes 413, 4211, act as a limiter for the locking member, ensuring stable compression and thereby locking the sleeve 421 and the two adjacent connecting shafts 41. Exemplarily, the locking member is a jackscrew.

[0065] like Figure 2 As shown, in a specific embodiment, the number of the first assembly holes 4211 and the second assembly holes 413 ranges from 2 to 4, and the number of the locking members corresponds to the number of the first assembly holes 4211 and the second assembly holes 413, so as to enhance the locking effect and facilitate the assembly and disassembly of the locking members. For example, the number of the first assembly holes 4211 and the second assembly holes 413 is set to 2, 3, or 4.

[0066] like Figure 4 As shown, in a further embodiment, among any two adjacent connecting shafts 41, one of the connecting shafts 41 is provided with a keyway 414, and the connecting shaft 41 and the sleeve 421 are connected by a key, and the sleeve 421 and the connecting shaft 41 jointly transmit torque with the other connecting shaft 41 to enhance the torque transmission effect between any two adjacent connecting shafts 41 and promote stable power transmission.

[0067] In another specific embodiment, among any two adjacent connecting shafts 41, the locking piece passes through one of them, and the other is provided with a connecting hole. The locking piece is connected to the hole wall of the connecting hole to enhance the limiting effect, and the way in which the locking piece is connected to the hole wall of the connecting hole can make the locking of any two adjacent connecting shafts 41 more reliable.

[0068] like Figure 6As shown, in an optional embodiment, the conveying device 100 also includes a lifting mechanism 50, which is installed on the frame 10, and the frame 10 provides support for the lifting mechanism 50; at least one of the first conveying unit 20 and the second conveying unit 30 is connected to the lifting mechanism 50, and can be lifted and lowered in the vertical direction under the action of the corresponding lifting mechanism 50, and the lifting mechanism 50 provides a lifting power source and stable support during lifting and lowering for at least one of the first conveying unit 20 and the second order feeder.

[0069] like Figure 6 As shown, in a further embodiment, the lifting mechanism 50 includes a lifting power source 51 and a synchronous lifter 52 connected to the lifting power source 51; at least one of the first conveyor unit 20 and the second conveyor unit 30 is connected to the corresponding synchronous lifter 52. In this way, the lifting power source 51 provides a power source for the lifting and lowering of at least one of the first conveyor unit 20 and the second conveyor unit 30. The lifting power source 51 can transmit power to the synchronous lifter 52, which provides support for at least one of the first conveyor unit 20 and the second conveyor unit 30, promoting the smooth lifting and lowering of at least one of the first conveyor unit 20 and the second conveyor unit 30.

[0070] Exemplarily, the first conveying unit 20 is connected to the synchronous lifter 52 ; or, the second conveying unit 30 is connected to the synchronous lifter 52 ; or, the first conveying unit 20 and the second conveying unit 30 are respectively connected to corresponding synchronous lifters 52 .

[0071] For example, the lifting power source 51 may be a pneumatic cylinder, a hydraulic cylinder, or the like.

[0072] like Figure 5 As shown, in some embodiments, the conveying device 100 further includes a conveying power source 60, which is connected to the connecting shaft 41. The conveying power source 60 can provide power to the first conveying mechanism 21 or the second conveying mechanism 31, and the connecting shaft 41 transmits the power to the corresponding first conveying mechanism 21 or second conveying mechanism 31. In other words, the connecting shaft 41 can not only drive the first conveying mechanism 21 or the second conveying mechanism 31 to adjust the spacing, but also transmit power, achieving a dual purpose.

[0073] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, in some embodiments, the first conveying mechanism 21 and / or the second conveying mechanism 31 adopts belt drive or roller drive. Belt drive can mitigate load impact, reduce vibration, and make transmission smoother. Roller drive can handle the transportation of a large number of flat-bottomed items and is easy to assemble into different production lines. For example, the first conveying mechanism 21 adopts belt drive and the second conveying mechanism 31 adopts roller drive; or, the first conveying mechanism 21 adopts roller drive and the second conveying mechanism 31 adopts belt drive; or, both the first conveying mechanism 21 and the second conveying mechanism 31 adopt belt drive; or, both the first conveying mechanism 21 and the second conveying mechanism 31 adopt roller drive.

[0074] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the first conveying mechanism 21 uses a belt drive, while the second conveying mechanism 31 uses a roller drive. The first conveying mechanism 21 includes a driving wheel 211, a driven wheel 212, and a conveyor belt 213. The conveyor belt 213 is tensioned between the driving wheel 211 and the driven wheel 212. A connecting shaft 41 is sleeved around the driving wheel 211 and / or the driven wheel 212. The connecting shaft 41 transmits power to the driving wheel 211. The driving wheel 211 and the driven wheel 212 work together to transmit power to the conveyor belt 213. The conveyor belt 213 continuously conveys items, promoting efficient transportation. Furthermore, part of the second conveying mechanism 31 includes a driving roller 311, while another part of the second conveying mechanism 31 includes a driven roller 312. The driving roller 311 is powered by a built-in motor and can actively rotate around its own axis to drive the material forward. The driven roller 312 supports the material and guides its movement.

[0075] The technical features of the above-mentioned embodiments can be combined arbitrarily.
