Description

Technical Field

[0001] The utility model relates to the technical field of conveying structures, in particular to a paperboard conveying structure. Background Art

[0002] The conveying structure generally includes a conveying belt, and the two ends of the conveying belt are respectively wound around a driving wheel and a driven wheel. The driving wheel is driven by a driving motor, so that the conveying belt and the driven wheel are both rotated, and the material can be placed on the conveying belt, and the material can be transported from one end to the other end by the conveying belt. In the prior art, cardboard is also transported using a conveying structure during processing, but the cardboard is generally light in weight. During the transportation process, if the speed of the conveying belt is fast, the cardboard may be separated from the conveying belt, and thus may fall from the conveying belt. In order to prevent the cardboard from falling, the running speed of the conveying belt can only be maintained at a low level, and the subsequent processing also needs to reduce the speed accordingly, resulting in low overall processing efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a cardboard conveying structure, which solves the problem in the prior art that the cardboard may be separated from the conveying belt due to the high speed of the conveying belt.

[0005] In the above embodiment, the conveyor belt is arranged in a ring similar to that in the prior art, but the difference is that an installation box is also arranged in the ring, and the upper section of the conveyor belt covers the installation box. The cardboard is placed on the conveyor belt during transportation and covers the connecting holes thereon, and the exhaust pipe is connected to the external exhaust fan, so that negative pressure is generated in the installation box during operation, and the cardboard is sucked onto the conveyor belt through the connecting holes and is not easy to be detached. Therefore, the speed of the conveyor belt can be appropriately increased without causing the cardboard and the conveyor belt to be separated, which solves the problem in the prior art that the fast conveyor belt speed may cause the cardboard and the conveyor belt to be separated.

[0006] Furthermore, a plurality of first balls are rollingly mounted on the top surface of the first limiting strip.

[0007] Furthermore, two sides of the conveyor belt are overlapped with two sides of the through frame respectively.

[0008] Furthermore, a pair of second limiting strips located on both sides of the conveyor belt are fixedly connected to the bottom surface of the installation box.

[0009] Furthermore, the communication holes are arranged in regular rows on the conveyor belt, and a plurality of second balls staggered with the communication holes are arranged on the bottom surface of the installation box, and the conveyor belt abuts against all the second balls.

[0010] Furthermore, all the communication holes can be communicated with the through frame.

[0011] Furthermore, the lower end surface of the second limiting strip is located below the lower end surface of the conveyor belt.

[0012] Furthermore, there are multiple installation boxes arranged side by side in transverse direction.

[0013] Furthermore, a plurality of exhaust pipes are equidistantly arranged on the installation box.

[0014] Furthermore, a pair of mounting arms are fixedly mounted at both ends of the mounting box, the driving wheel and the driven wheel are respectively mounted between the two pairs of mounting arms, and the driving motor is mounted on one of the mounting arms.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] By arranging a connecting hole on the conveying belt and arranging an installation box in the ring, and connecting it with an external exhaust fan through an exhaust pipe, negative pressure is generated in the installation box during operation, and the cardboard is sucked onto the conveying belt through the connecting hole and is not easy to be detached. Therefore, the speed of the conveying belt can be appropriately increased without causing the cardboard and the conveying belt to be detached, thereby solving the problem in the prior art that the fast conveying belt speed may cause the cardboard and the conveying belt to be detached.

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In an exemplary embodiment, Figure 1-5 As shown, the present embodiment provides a cardboard conveying structure, which includes a long strip installation box 1, at both ends of which a driving wheel 2 and a driven wheel 3 are rotatably installed, a conveying belt 4 is wound around the driving wheel 2, the installation box 1 and the driven wheel 3, wherein a plurality of connecting holes 5 are opened on the conveying belt 4; a long strip through frame 6 extending from one end to the other end is arranged on the top surface of the installation box 1, and the conveying belt 4 covers the through frame 6 and the two can move relatively, and an exhaust pipe 7 connected to the side wall of the installation box 1 is also fixedly connected; a pair of first limit strips 8 located on both sides of the conveying belt 4 are also fixedly connected to the top surface of the installation box 1, and the upper end surface of the conveying belt 4 is higher than the two first limit strips 8; and a driving motor 9 for driving the driving wheel 2 to rotate is also included.

[0027] In the above embodiment, the conveyor belt 4 is arranged in an annular shape similar to that in the prior art. During operation, the driving motor 9 drives the driving wheel 2 to rotate, thereby rotating the annular conveyor belt 4 and the driven wheel 3, and the conveyor belt 4 can operate. The difference is that an installation box 1 is also arranged in the annular shape of the conveyor belt 4 (i.e., between the driving wheel 2 and the driven wheel 3), and the upper section of the conveyor belt 4 covers the installation box 1. The cardboard 10 is placed on the conveyor belt 4 during transportation and covers the connecting hole 5 thereon, and the exhaust pipe 7 is connected to the external exhaust fan 15. During operation, negative pressure is generated in the installation box 1, and the cardboard 10 is sucked onto the conveyor belt 4 through the connecting hole 5, and is not easy to be detached, so the conveyor belt 4 The speed can be appropriately increased without causing the cardboard 10 to separate from the conveyor belt 4, which solves the problem in the prior art that the faster conveyor belt 4 may cause the cardboard 10 to separate from the conveyor belt 4; after the cardboard 10 is conveyed from one end to the other end, it continues to move with the conveyor belt 4 and gradually separates from the conveyor belt 4, thereby entering the next process, so that the conveying speed of the cardboard 10 is accelerated, and the subsequent processes can also be accelerated, thereby improving the overall processing efficiency; more specifically, all the connecting holes 5 can be connected to the through frame 6, so that these connecting holes 5 can all play the role of adsorbing the cardboard 10; in order to adapt to wider cardboards 10, the installation box 1 can also be arranged into multiple horizontally side by side according to the situation.

[0028] In a specific exemplary embodiment, Figure 1-5 As shown, the first limit strip 8 is located on both sides of the conveyor belt 4, which can prevent the conveyor belt 4 from shifting during operation. Furthermore, a plurality of first balls 11 are rollingly installed on the top surface of the first limit strip 8. These first balls 11 can roll, and when the cardboard 10 is covered on the first limit strip 8, the cardboard 10 can also be connected with the first balls 11, thereby obtaining the rolling support of the first balls 11, and does not move relative to the first limit strip 8, thereby ensuring that the cardboard 10 is not worn; more specifically, the two sides of the conveyor belt 4 are overlapped with the two sides of the through frame 6 respectively, so that the through frame 6 can be covered more completely, avoiding air leakage on the side of the through frame 6, and also providing support for the two sides of the conveyor belt 4 to avoid the conveyor belt 4 from collapsing downward.

[0029] In a further exemplary embodiment, Figure 1-5 As shown, a pair of second limit strips 12 located on both sides of the conveyor belt 4 are fixedly connected to the bottom surface of the installation box 1. Similar to the first limit strip 8, the second limit strip 12 provides limitation for both sides of the conveyor belt 4 below the installation box 1 to prevent the conveyor belt 4 from shifting and ensure stable operation; further, the lower end surface of the second limit strip 12 is located below the lower end surface of the conveyor belt 4, which can better block the conveyor belt 4 and limit it between the two second limit strips 12.

[0030] In a more detailed exemplary embodiment, Figure 1-5 As shown, the connecting holes 5 are arranged in regular rows on the conveyor belt 4, and a plurality of second balls 13 staggered with the connecting holes 5 are also arranged on the bottom surface of the installation box 1. The second balls 13 can also roll, and the conveyor belt 4 rests on all the second balls 13. The second balls 13 are arranged below the installation box 1 to provide rolling support for the conveyor belt 4, which can facilitate the smooth operation of the conveyor belt 4.

[0031] In a further exemplary embodiment, Figure 1-5 As shown, a pair of mounting arms 14 are fixedly installed at both ends of the mounting box 1, the driving wheel 2 and the driven wheel 3 are respectively installed between the two pairs of mounting arms 14, and the driving motor 9 is installed on one of the mounting arms 14. The mounting arms 14 provide a mounting base for the driving wheel 2, the driven wheel 3 and the driving motor 9. At the same time, the connection between the driving wheel 2, the driven wheel 3 and the conveying belt 4 is the same as that in the prior art. The difference is that the mounting box 1 and the first ball 11 and the second ball 13 are provided to support the conveying belt 4 in the middle section, so that the operation of the conveying belt 4 can be more stable, and the conveying belt 4 and the driving wheel 2 and the driven wheel 3 can be connected by toothed belt meshing to increase the connection stability and prevent slipping during operation, that is, an elastic continuous rack is provided on the inner wall of the conveying belt 4. A toothed belt is formed, and corresponding meshing annular toothed belts are arranged on the driving wheel 2 and the driven wheel 3, so as to ensure the stable operation of the conveying belt 4; in particular, the continuous toothed belt may cause greater friction between the conveying belt 4 and the installation box 1. At the same time, the negative pressure in the installation box 1 may also increase the pressing force between the conveying belt 4 and the installation box 1, but under the drive of the driving wheel 2, the friction and the pressing force can be overcome to make the conveying belt 4 run smoothly. Air leakage may also occur on the side of the conveying belt 4, but this will not affect the adsorption of the cardboard 10, and can also increase the suction effect, that is, in this solution, a number of exhaust pipes 7 are equidistantly arranged on the installation box 1, and suction force is provided at various positions in the length direction to ensure the stable adsorption of the cardboard 10 until the cardboard 10 is disengaged from the conveying belt 4.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
