[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0027] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directionality indications also change accordingly.

[0028] In addition, the description of “first”, “second” and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first”, “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those skilled in the art. When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope of the present application.

[0029] The present application provides a layered device, which is configured in a paper feeding device.

[0030] In an embodiment of the present application, with reference to the accompanying Figure 1As shown, the paper feeding device comprises a conveying table and a baffle located above the conveying table, the distance between the baffle and the conveying table is slightly greater than the thickness of a piece of paper to be fed, so that the paper to be fed stacked on the conveying table and abutting against one side of the baffle is conveyed out one by one through the baffle and the conveying table. The layering device 1 comprises a support 12 and positioning shafts 11, the positioning shafts 11 are connected to the support 12 and are spaced apart above the conveying table, the positioning shafts 11 are located opposite to the baffle and the distance between the positioning shafts 11 and the baffle is less than the length of the paper to be fed, wherein it is to be noted that the length of the paper to be fed is the length of the paper to be fed in the conveying direction of the conveying table.

[0031] It can be understood that when the height of the first paper to be fed stacked below the positioning shafts 11 approaches the positioning shafts 11, if the paper to be fed is continuously put between the positioning shafts 11 and the baffle, at this time, the paper to be fed put in is arranged in an inclined manner, one end of which abuts against the baffle and the first paper to be fed, and the other end of which abuts against the positioning shafts 11, that is, at this time, the paper to be fed put in is separated from the first paper to be fed, and the paper to be fed continuously put in is stacked on the paper to be fed arranged in an inclined manner, thereby forming a second paper to be fed arranged in an inclined manner and separated from the first paper to be fed, and when the first paper to be fed below is conveyed out, due to the decrease of the height of the first paper to be fed, the paper to be fed below the second paper to be fed falls automatically to supplement the first paper to be fed.

[0032] In this way, the second paper to be fed is arranged in a layered manner with the first paper to be fed, so that the first paper to be fed maintains a fixed stacking quantity during the conveying of the paper, greatly reduces the pressure on the paper to be fed at the bottom, and avoids the phenomenon that the paper to be fed is not conveyed smoothly, the conveyed corrugated paper is inclined, or even the corrugated paper cannot be conveyed and is stuck when the conveying force of the conveying wheel set is not enough.

[0033] In an embodiment, the layering device comprises an adjusting assembly, the adjusting assembly comprises a rotating shaft 13 and a driving mechanism, the rotating shaft 13 is rotatably connected to the support 12, the rotating shaft 13 is fixedly connected to the positioning shafts 11, and the driving mechanism is used to drive the rotation of the rotating shaft 13 to adjust the position of the positioning shafts 11 in the direction away from or close to the baffle.

[0034] Therefore, the positioning shaft 11 can be driven to move by the driving mechanism to adjust the distance between the positioning shaft 11 and the baffle plate, so as to be suitable for conveying paperboards with different length sizes. For example, when a paperboard with a short length size needs to be conveyed, the positioning shaft 11 is driven to move by the driving mechanism, and the position of the positioning shaft 11 is adjusted towards the baffle plate to shorten the distance between the positioning shaft 11 and the baffle plate, so as to be suitable for the length size of the paperboard. When a paperboard with a long length size needs to be conveyed, the positioning shaft 11 is driven to move by the driving mechanism, and the position of the positioning shaft 11 is adjusted away from the baffle plate to increase the distance between the positioning shaft 11 and the baffle plate, so as to be suitable for the length size of the paperboard.

[0035] Specifically, the support 12 is fixedly installed on the rack of the paper conveying device, or the support 12 is slidably installed on the rack of the paper conveying device, so that the position of the positioning shaft 11 can be adjusted in a larger range, and the positioning shaft 11 can be suitable for conveying more paperboards with different length sizes.

[0036] In an embodiment, the positioning shaft 11 is arranged in parallel with the rotating shaft 13, and a support 14 is arranged between the positioning shaft 11 and the rotating shaft 13. The support 14 is detachably connected with the rotating shaft 13 and / or the positioning shaft 11.

[0037] Specifically, one end of the support 14 is fixedly connected with the positioning shaft 11, and the other end is clamped to the rotating shaft 13 by a locking bolt.

[0038] In an embodiment, a groove for accommodating the rotating shaft 13 is formed on the side of the support 12 away from the baffle plate. The support 12 is provided with a slot, and the slot is in communication with the groove and is used for allowing the support 14 to pass through.

[0039] Specifically, the positioning shaft 11 is located on the side of the support 12 facing the baffle plate, the rotating shaft 13 is located on the side of the support 12 away from the baffle plate, the number of supports 14 is two, and the two supports 14 are arranged in parallel between the positioning shaft 11 and the rotating shaft 13. Each support 14 passes through a slot, so that the two ends of the support 14 are connected with the positioning shaft 11 and the rotating shaft 13, respectively.

[0040] Specifically, two fixed plates are arranged in parallel in the groove of the support 12. The two fixed plates are respectively provided with through holes in alignment. The two ends of the rotating shaft 13 are rotatably inserted into the two through holes, respectively. The two ends of the rotating shaft 13 are respectively provided with limiting blocks which are sleeved on the rotating shaft 13 and are located between the two fixed plates, so as to axially limit the rotating shaft 13.

[0041] In an embodiment, the driving mechanism includes a screw rod 15 and a nut 16. The screw rod 15 is rotatably arranged on the support 12 and is arranged perpendicularly to the rotating shaft 13. The nut 16 is movably connected to one side of the rotating shaft 13 and is sleeved on the screw rod 15.

[0042] Thus, by rotating the screw rod 15, the nut 16 is driven to move on the screw rod 15, and the movement of the nut 16 drives the rotation of the rotating shaft 13, so as to drive the rotation of the rotating shaft 13 to adjust the position of the positioning shaft 11.

[0043] Specifically, the screw rod 15 and the nut 16 are located on the side of the support 12 away from the baffle, i.e. on the same side of the rotating shaft.

[0045] In this embodiment, the positioning sleeve fixes and limits the screw rod 15 in the axial direction, and the positioning sleeve can swing up and down relative to the first fixing seat 17 (i.e. relative to the support 12), so that the screw rod 15 can also swing up and down relative to the first fixing seat 17 (i.e. relative to the support 12), thereby avoiding the problem of being stuck during the rotation of the screw rod 15 to drive the movement of the nut 16, and also allowing the rotating shaft 13 to have a larger rotation range, i.e. allowing the positioning shaft 11 to have a larger position adjustment range.

[0046] Specifically, the first fixing seat 17 comprises a first fixing part and a first connecting part, the first fixing part is fixedly connected to the side plate of the support 12 by bolts, the first connecting part is fixedly connected to the first fixing part by bolts, and a first through groove for accommodating the positioning sleeve is formed between the first fixing part and the first connecting part. The positioning sleeve has two rotating rods protruding from opposite sides thereof, and the two rotating rods are rotatably arranged in the two opposite side walls of the first through groove, so as to realize the pivoting of the positioning sleeve to the first fixing seat 17.

[0047] In an embodiment, the driving mechanism further comprises a second fixing seat 18 fixedly connected to one side of the rotating shaft 13, and the nut 16 is pivotally connected to the second fixing seat 18.

[0048] In this way, when the screw rod 15 rotates, the nut 16 moves on the screw rod 15 due to the threaded cooperation between the nut 16 and the screw rod 15. In this process, the screw rod 15 and the nut 16 also swing up and down synchronously, and finally the nut 16 rotates around the axis of the rotating shaft 13, thereby driving the rotating shaft 13 to rotate through the second fixing seat 18.

[0049] Specifically, the second fixing seat 18 comprises a second fixing part and a second connecting part, the second fixing part is fixedly connected to one end of the rotating shaft 13 by a bolt, the second connecting part is fixedly connected to the second fixing part by a bolt, a second through slot for accommodating the nut 16 is formed between the second fixing part and the second connecting part, opposite sides of the nut 16 are provided with rotating rods, and the two rotating rods are rotatably arranged on two opposite side walls of the second through slot, so that the nut 16 is pivotally connected to the second fixing seat 18.

[0050] In an embodiment, the screw rod 15 is fixedly connected with a rotating handle at an end away from the nut 16, and the rotating handle is used for being held and rotated by an operator to realize rotation of the screw rod 15.

[0051] In an embodiment, referring to the accompanying drawings Figure 4 As shown in the drawings, the support 12 has a supporting part 121, which is arranged in a spaced manner with the positioning shaft 11 in the vertical direction and is flush with the table top of the conveying table, and is used for carrying the paperboard to be sent, the supporting part 121 is formed on the side of the support 12 facing the baffle, and is used for supporting the tail end of the stack of paperboard to be sent away from the baffle.
