Description

Technical Field

[0001] This utility model relates to the technical field of conveying equipment for cardboard box processing, and in particular to a cardboard anti-jump conveying component and cardboard conveying system. Background Technology

[0002] Cardboard boxes are important transit containers in modern logistics. They are generally made from corrugated cardboard, and the cardboard processing involves multiple conveying steps to transfer the cardboard between these stages. In actual processing, belt conveyor systems are typically used. To improve efficiency, these systems can consist of multiple conveyor belts to accommodate various conveying requirements. However, in some cases, cardboard may skip over the conveyor belt during transfer, flying off the previous belt and not landing correctly on the next one. This is especially true when there is a height difference between the two conveyor belts. Skipped cardboard requires manual retrieval, reducing overall efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cardboard anti-jump conveying component, which solves the problem that cardboard may jump when there is a height difference, resulting in a decrease in overall efficiency.

[0004] According to an embodiment, a cardboard anti-jump conveyor assembly is provided, which includes a first conveyor belt and a second conveyor belt located obliquely below one end of the first conveyor belt. An upper pressure roller group and a lower support roller group are also arranged between the first and second conveyor belts at intervals. A first mounting shaft and a second mounting shaft located below the first mounting shaft are also fixedly arranged between the first and second conveyor belts. The upper pressure roller group includes a plurality of first rollers rotatably sleeved on the first mounting shaft. The lower support roller group includes a plurality of second rollers fixedly sleeved on the second mounting shaft. The second mounting shaft is also connected to a drive motor that drives its rotation. A fixing block is also fixedly connected to the first mounting shaft. A crossbar is detachably connected to the fixing block, and the two ends of the crossbar are respectively close to the first and second conveyor belts. A plurality of flexible strips are also detachably connected to the end of the crossbar close to the second conveyor belt. The flexible strips are closed and fall downward in an arc shape towards the upper end of the second conveyor belt. A pair of upper pressure rollers and lower support rollers are set between the first and second conveyor belts for the paperboard to pass through. After passing through, the paperboard will first contact the flexible strip, and then fall downward under the action of the flexible strip, and finally fall correctly onto the second conveyor belt. This can effectively avoid paper jumping and solve the problem in the prior art that paper jumping may occur when there is a height difference in the paperboard, which will reduce the overall efficiency.

[0005] Furthermore, at least two fixing blocks are installed on the first mounting shaft.

[0006] Furthermore, a stop plate is detachably connected to the fixing block, and a first half-ring and a second half-ring are respectively provided on the stop plate and the fixing block. The first half-ring and the second half-ring together form a ring through which the crossbar passes.

[0007] Furthermore, the fixing block and the abutment are detachably connected via a first connector.

[0008] Furthermore, a mounting block is detachably connected to one end of the crossbar near the second conveyor belt. The mounting block is also detachably connected to a top plate. One side of the top plate is recessed and has an inlet groove, which is covered by the mounting plate. The top plate also has multiple through holes penetrating the inlet groove. A connecting plate is installed inside the inlet groove. A flexible strip is fixedly connected to the connecting plate and can pass through the through holes.

[0009] Furthermore, a connecting column is fixedly connected to the side of the mounting block facing away from the top plate, and the connecting column is threadedly connected to the end of the crossbar.

[0010] Furthermore, the top plate and the mounting block are detachably connected via multiple second connectors.

[0011] According to an embodiment, a cardboard conveying system including the above-described cardboard anti-jump conveying assembly is also provided.

[0012] Compared with the prior art, the present invention has the following beneficial effects: A flexible strip is installed between the first and second conveyor belts to ensure that the cardboard falls correctly onto the second conveyor belt. This effectively prevents paper from jumping, eliminating the need for manual picking up of the cardboard and thus improving overall efficiency. This solves the problem in the prior art where paper jumping can occur when there is a height difference, leading to a decrease in overall efficiency. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-4As shown, this embodiment provides a paperboard conveying system that can prevent paper jumping during paperboard conveying. The conveying system includes a paperboard anti-jump conveying assembly, which includes a first conveyor belt 1 and a second conveyor belt 2 located diagonally below the first conveyor belt 1. This is equivalent to two conveyor belts with a height difference in the prior art. The paperboard 3 transitions from the first conveyor belt 1 to the second conveyor belt 2. Unlike the prior art, this solution, to ensure no paper jumping occurs, provides a first mounting shaft 4 and a second mounting shaft 5 positioned vertically opposite each other between the first conveyor belt 1 and the second conveyor belt 2. The first mounting shaft 4 is fixed, while the second mounting shaft 5 is rotatable. The conveying assembly also includes a component connected to the second mounting shaft 5 to drive the second mounting shaft. The drive motor that drives the rotation of shaft 5 has multiple first rollers 6 rotatably mounted on the first mounting shaft 4, and multiple second rollers 7 fixedly mounted on the second mounting shaft 5. The multiple first rollers 6 and multiple second rollers 7 respectively form an upper pressure roller group and a lower support roller group. The cardboard 3 is conveyed on the first conveyor belt 1 and can enter and pass between the upper pressure roller group and the lower support roller group. During the process, the drive motor runs, causing the second mounting shaft 5 to rotate, so that the second rollers 7 can assist the cardboard 3 to pass through. Furthermore, a fixing block 8 is fixedly connected to the first mounting shaft 4. A crossbar 9 is detachably connected to the fixing block 8, and the two ends of the crossbar 9 are close to the first conveyor belt 1 and the second conveyor belt 2 respectively. The end of the crossbar 9 close to the second conveyor belt 2 can also be detachably connected to... Several flexible strips 10 are arranged together and fall downwards in an arc shape towards one end of the second conveyor belt 2. In particular, the first roller 6 and the second roller 7 are both made of elastic material and have an outer ring. The outer ring is in direct contact with the cardboard 3. The elastic material (such as rubber) can avoid excessive compression of the cardboard 3 and has greater friction to assist the cardboard 3 to pass through smoothly (there is a vertical gap between the first roller 6 and the second roller 7 that is greater than the thickness of the cardboard 3. The second roller 7 provides a push during the passage of the cardboard 3, and the first roller 6 prevents the cardboard 3 from tilting upwards). During the passage of the cardboard 3, the cardboard 3 will first contact the falling flexible strips 10 and move downwards under the downward pressure and guidance of the flexible strips 10 [1] and fall correctly. On the second conveyor belt 2, paper skipping can be effectively avoided, solving the problem in the prior art where paper skipping may occur when there is a height difference in the cardboard 3, resulting in a decrease in overall efficiency. Specifically, the flexible strip 10 can be a thin rod made of nylon with a small diameter and a long length, and good toughness. One end is fixed, and the other end can fall in an arc shape under gravity. For example, it can have a diameter of 1mm and a length of 30-50cm, which can be adjusted according to the specific distance between the first conveyor belt 1 and the second conveyor belt 2. Furthermore, an appropriate number of fixing blocks 8 can be set on the first mounting shaft 4 as needed, such as two fixing blocks 8, so that there are two sets of flexible strips 10, which can better block the cardboard 3 from above.

[0016] like Figure 1 , 2As shown, a stop plate 11 is detachably connected to the fixing block 8, and a first half ring 12 and a second half ring 13 are respectively provided on the stop plate 11 and the fixing block 8. The first half ring 12 and the second half ring 13 together form a ring through which the crossbar 9 passes. The fixing block 8 and the stop plate 11 are detachably connected by a first connector 14 to clamp the crossbar 9 between them. The first connector 14 can be a screw to facilitate the adjustment of the connection position of the crossbar 9, thereby indirectly adjusting the position of the flexible strip 10.

[0017] like Figure 1 , 3 As shown in Figure 4, a mounting block 15 is detachably connected to one end of the crossbar 9 near the second conveyor belt 2. The mounting block 15 is also detachably connected to a top plate 16. One side of the top plate 16 has a recessed groove, and the mounting plate can cover the groove. The top plate 16 also has multiple through holes 17 penetrating the groove. A connecting plate 18 is installed inside the groove. The flexible strip 10 is fixedly connected to the connecting plate 18, and the flexible strip 10 can pass through the through holes 17. That is, the diameter of the through holes 17 is larger than the diameter of the flexible strip 10, so that the connecting plate 18 can be easily removed for replacement and maintenance of the flexible strip 10. The top plate 16 and the mounting block 15 can be detachably connected by multiple second connecting rods 19, which can also be screws. In a further embodiment, a connecting post 20 is fixedly connected to the side of the mounting block 15 away from the top plate 16. The connecting post 20 is threadedly connected to the end of the crossbar 9, thus realizing the detachable connection between the mounting block 15 and the crossbar 9.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
