It possesses high mechanical strength and can withstand impacts and drops during handling. During the production of corrugated cardboard, it is necessary to inspect the surface for defects.

[0003] Currently, the corrugated paper is typically placed on a conveyor belt and inspected by a testing device. After inspection, it is manually flipped and then placed back on the conveyor belt for re-inspection. This process is labor-intensive and time-consuming, and the operation is cumbersome, making it inconvenient to use. Therefore, it is necessary to design and modify the corrugated paper inspection conveyor to effectively prevent inconvenience and low inspection efficiency. Utility Model Content

A second motor is fixedly connected to the right side of the drive box, and the output end of the second motor is fixedly connected to the threaded rod with opposite threads.

[0007] As a preferred embodiment of the present invention, both the surface of the first limiting plate and the second limiting plate are provided with grooves, and the interior of the grooves is rotatably connected to a cylinder, the number of which is several.

[0008] As a preferred embodiment of this utility model, a bearing is fixedly connected inside the drive box, and the outer ring of the bearing is fixedly connected to the drive box, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0009] In a preferred embodiment of this utility model, a support column is fixedly connected to the top of the base plate, a sliding column is slidably connected inside the support column, the surface of the sliding column is provided with a number of slots, a bolt is threaded inside the support column, the bolt is inserted into the slot, and the sliding column is fixedly connected to the adjustment frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts the coordinated operation of the first and second conveyors, as well as the flipping mechanism composed of the movable frame, fixed clamp, movable clamp and electric cylinder, which can quickly and accurately flip the corrugated cardboard. With the image acquisition equipment on both sides, the front and back sides of the corrugated cardboard can be detected at the same time, which effectively shortens the detection time and significantly improves the detection efficiency. This device has the advantages of being easy to use and having high detection efficiency.

[0013] 2. This utility model, through the configuration of a drive box, a threaded rod, a movable column, a support frame, a first limiting plate, a second limiting plate, and a second motor, allows the operator to rotate the second motor according to the width of the corrugated cardboard to be tested. This rotation drives the threaded rod to rotate, which in turn moves the movable columns on both sides closer together, which in turn moves the support frames on both sides closer together, and then moves the first and second limiting plates closer together, until the cylindrical surfaces of the first and second limiting plates are in contact with the corrugated cardboard to be tested. This ensures the smooth transport of the corrugated cardboard. The movable and fixed clamps have a large area, resulting in a large contact area with the corrugated cardboard. Furthermore, the movable frame rotates stably and at a low speed, thus preventing the corrugated cardboard from bending when flipping. At the same time, due to its inherent structural characteristics, the corrugated cardboard itself has good hardness and bending resistance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4As shown, a corrugated cardboard inspection conveyor includes a base plate 1. A first conveyor 2 and a second conveyor 3 are fixedly connected to the top of the base plate 1. Vertical plates 4 are fixedly connected to the front and rear sides of the top of the base plate 1. A movable frame 5 is rotatably connected inside the vertical plate 4. A first motor 6 is fixedly connected to the surface of the vertical plate 4. The output end of the first motor 6 is fixedly connected to the movable frame 5. A fixed clamping plate 7 is fixedly connected to the surface of the movable frame 5. A sliding groove is provided on the surface of the movable frame 5, and a movable clamping plate 8 is slidably connected inside the sliding groove. An electric cylinder 9 is fixedly connected to the top of the movable frame 5, and the output end of the electric cylinder 9 is fixedly connected to the movable clamping plate 8. The height of the second conveyor 3 is greater than the height of the first conveyor 2. An adjusting frame 17 is provided above the base plate 1. A disc 18 is rotatably connected to both sides of the top of the adjusting frame 17. A support block 19 is fixedly connected to the top of the disc 18. A screen acquisition device 20 is rotatably connected inside the support block 19.

[0021] refer to Figure 1 A drive box 10 is fixedly connected to the surface of the first conveyor 2. A threaded rod with positive and negative threads is rotatably connected inside the drive box 10. Movable columns 11 are slidably connected to both sides inside the drive box 10. The threaded rod with positive and negative threads is threadedly connected to the movable columns 11. A support frame 13 is fixedly connected to the top of the movable column 11. A first limiting plate 14 is fixedly connected to the top of the left support frame 13. A second limiting plate 15 is fixedly connected to the front and rear sides of the top of the right support frame 13. A second motor 12 is fixedly connected to the right side of the drive box 10. The output end of the second motor 12 is fixedly connected to the threaded rod with positive and negative threads.

[0022] As a technical optimization of this utility model, through the configuration of the drive box 10, the positive and negative threaded rod, the movable column 11, the support frame 13, the first limiting plate 14, the second limiting plate 15, and the second motor 12, the operator can start the second motor 12 to rotate according to the width of the corrugated cardboard to be tested, thereby rotating the positive and negative threaded rod, which in turn drives the movable columns 11 on both sides to move closer to each other, which in turn drives the support frames 13 on both sides to move closer to each other, which in turn drives the first limiting plate 14 and the second limiting plate 15 to move closer to each other, until the cylinders 16 on the surfaces of the first limiting plate 14 and the second limiting plate 15 are in contact with the corrugated cardboard to be tested, thereby ensuring the smooth transport of the corrugated cardboard.

[0023] refer to Figure 1 The surfaces of the first limiting plate 14 and the second limiting plate 15 are both provided with grooves, and the interior of the grooves is rotatably connected to a cylinder 16, and the number of cylinders 16 is several.

[0024] As a technical optimization of this utility model, by setting the groove and the cylinder 16, the cylinder 16 can reduce the friction between the corrugated cardboard and the first limiting plate 14 and the second limiting plate 15 respectively, thereby ensuring the smooth conveying of the corrugated cardboard. The width of the corrugated cardboard is greater than the width of the first conveyor 2 and the second conveyor 3.

[0025] refer to Figure 3 The drive box 10 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 10, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0026] As a technical optimization of this utility model, by setting the bearing, the friction between the drive box 10 and the threaded rod can be reduced, thereby facilitating the rotation of the threaded rod.

[0027] refer to Figure 1 A support column 21 is fixedly connected to the top of the base plate 1. A sliding column 22 is slidably connected inside the support column 21. The surface of the sliding column 22 is provided with a slot, and there are several slots. A bolt 23 is threaded inside the support column 21. The bolt 23 is inserted into the slot. The sliding column 22 is fixedly connected to the adjustment frame 17.

[0028] As a technical optimization of this utility model, by setting up the support column 21, sliding column 22, slot and bolt 23, the operator can move the sliding column 22 up and down, thereby causing the adjustment frame 17 to move up or down, thereby driving the disc 18, support block 19 and image acquisition device 20 to move up or down. When the image acquisition device 20 moves to a suitable height, the operator tightens the bolt 23, so that the bolt 23 is inserted into the slot, thereby locking the height of the image acquisition device 20. By adjusting the height of the image acquisition device 20, it is easier to adjust the position of the image acquisition device 20, thereby facilitating better inspection of corrugated cardboard.

[0029] refer to Figure 2 Rubber plates 24 are fixedly connected to the surfaces of both the fixed clamping plate 7 and the movable clamping plate 8.

[0030] As a technical optimization of this utility model, by setting the rubber plate 24, the friction between the movable clamp 8 and the corrugated cardboard and the friction between the fixed clamp 7 and the corrugated cardboard can be increased, thereby facilitating the flipping of the corrugated cardboard. At the same time, the softness of the rubber plate 24 is used to protect the corrugated cardboard.

[0031] The working principle and usage process of this utility model are as follows: When in use, the operator places the corrugated cardboard to be inspected on the top of the first conveyor 2. Under the action of the first limiting plate 14 and the second limiting plate 15, the corrugated cardboard can be stably conveyed to the back side. During the conveying process, the image acquisition device 20 on the left side inspects the side of the corrugated cardboard that is located at the top. When the right side of the corrugated cardboard moves between the movable clamp 8 and the fixed clamp 7, the operator starts the electric cylinder 9 to extend, thereby driving the movable clamp 8 to move down and clamp the corrugated cardboard. Then, the first motor 6 is started to rotate 180 degrees. The first motor 6 is a servo motor. The rotation of the first motor 6 drives the movable frame 5, the fixed clamp 7, the movable clamp 8 and the corrugated cardboard to rotate 180 degrees. At this time, the corrugated cardboard is flipped over. At this time, the operator starts the electric cylinder 9 to retract, thereby releasing the clamping of the corrugated cardboard. Then, the second conveyor 3 is started to continue conveying the corrugated cardboard to the back side. During the conveying process, the image acquisition device 20 on the right side inspects the side of the corrugated cardboard that is located at the top, thereby inspecting both sides of the corrugated cardboard.

[0032] The operator can rotate the disc 18 as needed to drive the support block 19 and the image acquisition device 20 to rotate, thereby adjusting the angle of the image acquisition device 20. The operator can also rotate the image acquisition device 20 to adjust its tilt angle. Through the flexible adjustment of the image acquisition device 20, effective detection of corrugated cardboard can be ensured. The friction between the disc 18 and the adjustment frame 17 and the friction between the image acquisition device 20 and the support block 19 are used to achieve the purpose of position self-locking. The above content is common existing technology and common knowledge known to those skilled in the art. This application will not elaborate further.

[0033] The first conveyor 2 and the second conveyor 3 mentioned above are both common existing technologies and are common knowledge to those skilled in the art. Therefore, this application will not elaborate on them further. The image acquisition device 20 mentioned above is similar in principle to the image acquisition device mentioned in the utility model patent disclosed in CN220484779U, which discloses a corrugated cardboard inspection conveyor, and achieves the same effect. Therefore, this application will not elaborate on it further.
