Description

Technical Field

[0001] This utility model relates to the field of paperboard processing equipment technology, and in particular to a paperboard pressing structure and paperboard pressing system. Background Technology

[0002] The paper packaging industry generally uses corrugated paper as the material for processing packaging cartons. Corrugated paper is typically a multi-layered cardboard blank, and its processing involves steps such as gluing, bonding, and pressing. In specific processing steps, such as... Figure 1 As shown, after applying adhesive (i.e., coating with adhesive), the layers are bonded together to obtain a cardboard blank 1. The cardboard blank 1 is then conveyed to a pressing assembly via a conveyor belt for pressing. The pressing assembly typically uses a lower pressure roller 3 and an upper support roller 4 positioned vertically opposite each other, with a gap between them to allow the cardboard blank 1 conveyed by the conveyor belt to enter and press it, resulting in a tighter bond between the layers of the cardboard blank 1. In actual processing, after the conveyor belt delivers the cardboard blank 1 to the pressing assembly, as pressing proceeds, one end of the cardboard blank 1 becomes tighter due to pressure, and its thickness decreases accordingly. However, the portion of the cardboard blank 1 on the conveyor belt may separate, causing the adhesive between the layers to shift due to the pulling action. After the entire cardboard blank 1 has passed through the pressing assembly, uneven adhesive distribution between the layers may occur, ultimately leading to delamination of the cardboard during subsequent use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cardboard pressing structure that solves the problem that some cardboard located on the conveyor belt may separate during the pressing process, causing the adhesive to shift.

[0004] According to an embodiment, a cardboard pressing structure is provided, comprising a pair of laterally opposed mounting plates. A pressing assembly is disposed between one end of the two mounting plates. A drive roller and a driven roller are rotatably disposed between the two mounting plates at their respective ends. A conveyor belt is wound between the drive roller and the driven roller. The pressing assembly and the driven roller are positioned on opposite sides of the drive roller. A first mounting rod located above the conveyor belt is fixedly connected between the ends of the two mounting plates near the driven roller. A pressure plate is sleeved on the first mounting rod. The pressure plate extends downward at an incline towards the drive roller, and a roller is disposed at the end opposite to the first mounting rod. The roller can roll in contact with the conveyor belt below it. In this solution, the portion of the cardboard blank on the conveyor belt is also subjected to downward pressure during the pressing process, preventing separation and solving the problem in the prior art where the portion of the cardboard on the conveyor belt may separate during the pressing process, leading to adhesive displacement.

[0005] Furthermore, it also includes a first drive mounted on one of the mounting plates for driving the rotation of the active roller.

[0006] Furthermore, multiple pairs of first mounting wheels and second mounting wheels are fixedly mounted on the driving roller and the driven roller respectively. A conveyor belt is wound around each pair of first mounting wheels and second mounting wheels, and the multiple conveyor belts are equally spaced.

[0007] Furthermore, a second mounting rod is fixedly installed at the end of the pressure plate away from the first mounting rod. The two ends of the second mounting rod extend beyond the sides of the pressure plate and are respectively rotatably mounted with rollers. The rollers are rolled on two conveyor belts located on both sides of the pressure plate.

[0008] Furthermore, a pair of mounting seats are fixedly connected to the pressure plate, and the second mounting rod is fixedly passed through the two mounting seats.

[0009] Furthermore, fixed seats are fixedly connected to the two mounting plates respectively, and the two ends of the first mounting rod are fixedly connected to the two fixed seats respectively.

[0010] Furthermore, a mounting sleeve is fixedly connected to the end of the pressure plate away from the roller, and the mounting sleeve is rotatably fitted onto the first mounting rod.

[0011] Furthermore, the pressing assembly includes a lower pressure roller and an upper support roller that are positioned opposite each other.

[0012] Furthermore, a support strip located between the driving roller and the driven roller is fixedly connected between the two mounting plates, and the conveyor belt skin is also wrapped around the support strip.

[0013] According to an embodiment, a paperboard pressing system including the above-described paperboard pressing structure is also provided.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] A pressure plate is installed above the conveyor belt. One end of the pressure plate can press down on the cardboard blank to ensure that the part of the cardboard on the conveyor belt is also subjected to downward pressure during the pressing process, thus preventing separation. This solves the problem in the prior art where the part of the cardboard on the conveyor belt may separate during the pressing process, causing the adhesive to shift. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-4As shown, this embodiment provides a paperboard pressing system for pressing paperboard blanks 1. The pressing system includes a paperboard pressing structure, which includes a pair of horizontally opposed mounting plates 2. A pressing component similar to that in the prior art is provided between the two mounting plates 2, namely, a lower pressure roller 3 and an upper support roller 4 positioned vertically opposite each other. A gap is provided between the two to allow the paperboard blank 1 to enter and be pressed. A drive roller 5 and a driven roller 6 are rotatably arranged between the two mounting plates 2, located at their respective ends. The drive roller 5 and the driven roller 6 are located on the same side of the pressing component, with the drive roller 5 being closer to the pressing component. A conveyor belt 7 is also wound between the drive roller 5 and the driven roller 6. The conveyor belt 7 is used to feed the paperboard blank 1 into the pressing component for pressing. A first driver that drives the drive roller 5 to rotate is also fixedly installed on one of the mounting plates 2. The first driver includes a first drive motor. The machine 8 and the first reducer 9 connected to the first drive motor 8 (similarly, a second driver that drives the pressing assembly is also installed on one of the mounting plates 2, which also includes a second drive motor 10 and a second reducer 11. More specifically, the first driver and the second driver can be located outside the two mounting plates 2, so as to avoid occupying the space between the mounting plates 2), that is, one end of the drive roller 5 is connected to the first reducer 9. In this way, the operation of the first drive motor 8 can drive the drive roller 5 to rotate, and then drive the conveyor belt 7 to rotate, so that the cardboard blank 1 can move from one end to the pressing assembly and enter and pass through the pressing assembly; more specifically, the outer surface of the conveyor belt 7 can be provided with raised textures, which can increase the friction between the cardboard blank 1 and the conveyor belt 7 and prevent slippage between the cardboard blank 1 and the conveyor belt 7;More importantly, in this design, a pressure plate 12 is also installed above the conveyor belt 7. Specifically, a fixing seat 13 is fixedly connected to the ends of the two mounting plates 2 away from the pressing assembly. A first mounting rod 14 located above the conveyor belt 7 is fixedly connected between the two fixing seats 13. The pressure plate 12 is elongated and has a mounting sleeve 15 fixedly connected to one end. The mounting sleeve 15 is rotatably fitted onto the first mounting rod 14. The other end of the pressure plate 12 extends obliquely towards the pressing assembly and has mounting seats 16 fixedly connected to its bottom surface on both sides. A second mounting rod 17 passing through the two mounting seats 16 is also fixedly connected. Rollers 18 located on both sides of the pressure plate 12 are rotatably installed at both ends of the second mounting rod 17. That is, rollers 18 are provided on both sides of the end of the pressure plate 12 closest to the pressing assembly. The distance between one end of the pressure plate 12 and the conveyor belt 7 below is relatively large, while the distance between the other end and the conveyor belt 7 below is relatively small, and the rollers 18 can roll on the conveyor belt 7. In this way, the cardboard blank 1 enters from the end with the larger distance. The cardboard blank 1 is fed into the press assembly via the conveyor belt 7 and first contacts the roller 18. The pressure plate 12 can rotate relative to the first mounting rod 14. Thus, the cardboard blank 1, dragged by the conveyor belt 7, can smoothly pass through the roller 18 and continue forward, passing through the press assembly. During the pressing process, the portion of the cardboard blank 1 on the conveyor belt 7 is also subjected to downward pressure by the pressure plate 12 and the roller 18, thereby preventing separation. This solves the problem in the prior art where the portion of the cardboard on the conveyor belt 7 may separate during the pressing process, leading to adhesive displacement. Furthermore, the roller 18 is positioned close to the drive roller 5, allowing it to be closer. Although there is a distance between the roller 18 and the press assembly, this distance is small. After the cardboard blank 1 separates from the roller 18, although it is no longer subjected to downward pressure, most of the cardboard blank 1 has already passed through the press assembly, making separation of the remaining small portion less likely. Therefore, this significantly reduces the probability of subsequent cardboard delamination.

[0024] like Figure 1 As shown, multiple support strips 19 are fixedly connected between the two mounting plates 2 and between the drive roller 5 and the driven roller 6. The conveyor belt 7 is arranged around the support strips 19. The conveyor belt 7 located above the support strips 19 can be supported on the support strips 19 to prevent it from falling excessively downward, so that the conveyor belt 7 can have good contact with the cardboard blank 1 during operation.

[0025] like Figure 2-4As shown, the conveyor belt 7 in this scheme adopts a structure of multiple narrow conveyor belts 7. Specifically, multiple pairs of first mounting wheels 20 and second mounting wheels 21 are fixedly mounted on the driving roller 5 and driven roller 6, respectively. A conveyor belt 7 is wound between each pair of first mounting wheels 20 and second mounting wheels 21 (the conveyor belt 7 and the first mounting wheels 20 and second mounting wheels 21 can be meshed (i.e., they are respectively provided with meshing tooth structures), which can prevent slippage). The multiple conveyor belts 7 are arranged at equal intervals. The rollers 18 can be rolled on the two conveyor belts 7 located on both sides of the pressure plate 12. The cardboard blank 1 generally has a large width, which can cover the multiple conveyor belts 7 below the pressure plate 12. The rollers 18 apply downward pressure to the cardboard blank 1 on both sides, and the pressure plate 12 and the first mounting rod 14 can rotate relative to each other, which can prevent separation and at the same time avoid excessive downward pressure.

[0026] 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.
