Therefore, they should not be construed as limitations on this utility model.

[0036] Please see Figure 1 and Figure 9 The diagram shows a reversible corrugated cardboard production conveying device, which includes a frame 1. The frame 1 is equipped with a drive device 2, a reversing device 4, and a roller device 3. The drive device 2 provides rotational power to the roller device 3, and the reversing device 4 is used to reverse the direction of the roller device 3 to achieve the purpose of reversing the conveying of corrugated cardboard.

[0037] Please see Figure 3 The drive unit 2 includes multiple drive rollers 201, a drive motor 202, and connecting wheels 203. The two ends of the drive rollers 201 are connected to the frame 1 via bearing seats. This connection method ensures that the drive rollers 201 can rotate stably on the frame 1 while bearing certain axial and radial forces. Multiple drive rollers 201 are evenly arranged on the frame 1, and adjacent drive rollers 201 are connected by a sprocket and chain connection. This transmission method not only ensures synchronous rotation of all drive rollers 201 but also has high transmission efficiency and reliability. One drive roller 201 near the drive motor 202 is connected to the shaft of the drive motor 202 via a sprocket and chain connection. When the drive motor 202 starts, its power is transmitted to the connected drive roller 201 via the chain, thereby driving the other drive rollers 201 to rotate synchronously. Each drive roller 201 is equipped with multiple connecting wheels 203, which are key components for power transmission between the drive device 2 and the roller device 3.

[0038] Please see Figures 4 to 7The roller device 3 includes C-shaped channel steel 301 and roller assemblies 302. Multiple C-shaped channel steels 301 are equidistantly arranged on the frame 1, primarily serving as a mounting support platform for the roller assemblies 302. The C-shaped channel steels 301 are positioned above the drive device 2, ensuring effective cooperation between the roller assemblies 302 and the drive device 2. Each C-shaped channel steel 301 has multiple roller assemblies 302, evenly distributed across the corresponding C-shaped channel steel 301. This ensures uniform force distribution and smooth forward movement of the corrugated cardboard during transport. Furthermore, each roller assembly 302 is provided with a connecting wheel 203 at its lower end. The roller assembly 302 and the connecting wheel 203 are connected by a rubber connecting belt 5. The cross-section of the rubber connecting belt 5 is circular. This circular cross-section rubber connecting belt 5 has good flexibility and friction, which can effectively transmit the power of the driving roller 201 to the roller assembly 302, drive the components on the roller assembly 302 to rotate, thereby realizing the conveying of corrugated cardboard.

[0039] The roller assembly 302 includes a lower protective sleeve 302a, an upper base 302b with an internal circular cavity, a rotating base 302c with an internal circular cavity, a connecting shaft 302d, and a connecting pulley 302e. The lower protective sleeve 302a is located on the lower end face of the C-shaped channel steel 301, protecting the lower part of the roller assembly 302 from external impacts and damage. The upper base 302b is located on the upper end face of the C-shaped channel steel 301, and its internal cylindrical cavity is coaxial with that of the lower protective sleeve 302a, providing a stable support structure and guidance for the rotation of the rotating base 302c. The lower part of the rotating base 302c is fitted into the internal cavity of the upper base 302b, and the two are connected by a clearance fit, allowing the rotating base 302c to rotate flexibly on the upper base 302b. This design enables the roller assembly 302 to change its conveying direction under the action of the reversing device 4. Both ends of the connecting shaft 302d are fixedly connected to the two sides of the upper part of the rotating base 302c, ensuring the relative position stability of the connecting pulley 302e and the rotating base 302c. The connecting pulley 302e is connected to the connecting shaft 302d through bearings, allowing the connecting pulley 302e to rotate freely around the connecting shaft 302d, reducing frictional resistance. A V-shaped groove 302f is provided in the middle of the connecting pulley 302e, and the rubber connecting belt 5 is connected to the connecting wheel 203 through the V-shaped groove 302f. The design of the V-shaped groove 302f increases the contact area and friction between the rubber connecting belt 5 and the connecting pulley 302e, preventing the rubber connecting belt 5 from slipping during high-speed rotation and ensuring stable power transmission.

[0040] Please see Figure 5 , Figure 7 and Figure 8The reversing device 4 includes a reversing cylinder 401, a connecting plate 402, a transverse connecting rod 403, and a longitudinal connecting rod 404. Each rotating base 302c on each roller assembly 302 near the transverse connecting rod 403 is connected to the transverse connecting rod 403 via a rod end spherical bearing. Furthermore, the rotating bases 302c on multiple roller assemblies 302 on each C-shaped channel steel 301 are connected to the longitudinal connecting rod 404 via rod end spherical bearings. The use of rod end spherical bearings allows for relatively flexible rotation between the rotating bases 302c and the transverse and longitudinal connecting rods 403 and 404, while also transmitting a certain amount of force and torque, ensuring that each roller assembly 302 can change direction in a coordinated manner during reversing. The telescopic rod of the reversing cylinder 401 is connected to the connecting plate 402, and the other end of the connecting plate 402 is fixedly connected to the middle of the transverse connecting rod 403.

[0041] When it is necessary to reverse the conveying direction of corrugated cardboard, the telescopic rod of the reversing cylinder 401 extends or retracts, which drives the transverse connecting rod 403 to move through the connecting piece 402. In turn, the rotating base 302c connected to it rotates through the rod end joint bearing. At the same time, the rotating base 302c connected to the transverse connecting rod 403 drives the longitudinal connecting rod 404 to move, which in turn drives the other rotating bases 302c to rotate together, thereby achieving the purpose of reversing the conveying direction of the corrugated cardboard.

[0042] Please see Figure 6 The rotating base 302c has clearance surfaces 302g on both sides to facilitate the rotation of the connecting pulley 302e. The design of the clearance surfaces 302g can prevent the connecting pulley 302e from colliding or rubbing against the side of the rotating base 302c during rotation, ensuring that the connecting pulley 302e can rotate smoothly, guaranteeing the stability and reliability of power transmission, and improving the working efficiency and service life of the entire conveying device.

[0043] Please see Figure 1 It also includes a dustproof plate 6, the sides of which have a trapezoidal structure, and the dustproof plate 6 is evenly distributed on the frame 1. The trapezoidal structure of the dustproof plate 6 has a good dustproof effect, which can effectively reduce the entry of external dust and impurities into the conveying device, reduce the wear and tear of parts and the failure rate, and at the same time prevent dust from contaminating the corrugated cardboard, thus ensuring product quality.

[0044] Please see Figure 1 Multiple dustproof plates 6, one of which is equipped with a first proximity sensor 7 for controlling the timing of commutation.

[0045] In the production process of corrugated cardboard, accurate control of the reversing timing is crucial. The first proximity sensor 7 can monitor the position of the corrugated cardboard in real time. When the corrugated cardboard reaches the preset reversing position, the first proximity sensor 7 will send a signal to trigger the reversing device 4 to work, so that the roller assembly 302 can reverse in time, ensuring that the corrugated cardboard can be conveyed according to the predetermined path and direction, thereby improving the automation and accuracy of the production process.

[0046] Please see Figure 9 The system also includes a receiving device 8, which comprises a geared motor 801, a receiving shaft 802, a receiving sprocket 803, and a receiving rack 804. One end of the receiving rack 804 is connected to the bottom of the frame 1 via a bearing seat with a shaft, allowing it to be stably mounted on the frame 1 and withstand a certain weight. The other end extends beyond the lower part of the frame 1 to the side of the frame 1 to receive the corrugated sheets after reversing the conveying process. Both ends of the receiving shaft 802 are mounted on the frame 1 via bearing seats with shafts, ensuring stable rotation of the receiving shaft 802. The shaft of the geared motor 801 is connected to the receiving shaft 802 via a sprocket and chain connection. The geared motor 801 provides appropriate speed and torque, driving the receiving shaft 802 to rotate via sprocket and chain transmission. Two receiving sprockets 803 are symmetrically arranged on the receiving shaft 802. Connecting rods 805 are located on both sides of the receiving rack 804. Each receiving sprocket 803 has a receiving chain 806. One end of the receiving chain 806 is fixedly connected to the receiving sprocket 803 and then connected to the receiving sprocket 803 by winding. The other end is fixedly connected to the upper end of the connecting rod 805. When the geared motor 801 drives the receiving shaft 802 to rotate, the receiving sprockets 803 rotate accordingly. Through the winding and stretching of the receiving chain 806, the connecting rods 805 move up and down, thereby realizing the lifting function of the receiving rack 804. This allows the height of the receiving rack 804 to be automatically adjusted according to the stacking height of the corrugated cardboard, facilitating and quickly collecting the corrugated cardboard after reversing the conveying direction, improving receiving efficiency and production continuity.

[0047] Please see Figure 1 and Figure 9One of the multiple dustproof plates 6 is equipped with a second proximity sensor 9 and a third proximity sensor 10 on one side for controlling the lifting and lowering of the receiving device 8. The second proximity sensor 9 is positioned above the third proximity sensor 10. During the receiving process, the second proximity sensor 9 and the third proximity sensor 10 can monitor the stacking height of the corrugated cardboard on the receiving rack 804 in real time. When the corrugated cardboard stacks to a certain height, triggering the second proximity sensor 9, the receiving device 8 will initiate a lowering action, reducing the height of the receiving rack 804 to continue receiving more corrugated cardboard. When the corrugated cardboard stacks to a height that triggers the third proximity sensor 10 but not the second proximity sensor 9, the receiving device 8 will initiate an upward action, raising the height of the receiving rack 804 for better receiving of the corrugated cardboard. Through the coordinated use of the second proximity sensor 9 and the third proximity sensor 10, automated lifting and lowering control of the receiving device 8 is achieved, further improving the intelligence level and production efficiency of the entire corrugated cardboard production conveyor system.

[0048] Working principle:

[0049] In the production and conveying process of corrugated cardboard, the drive unit 2, as the power source, is started first. The drive motor 202 operates, and its power is transmitted sequentially to each drive roller 201 through the connection of the sprocket and the chain, causing the connecting wheel 203 on the drive roller 201 to start rotating. The roller assembly 302 in the roller device 3 is connected to the connecting wheel 203 through the rubber connecting belt 5. The rotation of the connecting wheel 203 drives the connecting pulley 302e on the roller assembly 302 to rotate, thereby causing the corrugated cardboard placed on the roller assembly 302 to be conveyed forward along the initially set direction by the rolling of the rollers.

[0050] When it is necessary to reverse the conveying direction of corrugated cardboard, the telescopic rod of the reversing cylinder 401 extends or retracts, which drives the transverse connecting rod 403 to move through the connecting piece 402. In turn, the rotating base 302c connected to it rotates through the rod end joint bearing. At the same time, the rotating base 302c connected to the transverse connecting rod 403 drives the longitudinal connecting rod 404 to move, which in turn drives the other rotating bases 302c to rotate together, thereby achieving the purpose of reversing the conveying direction of the corrugated cardboard.

[0051] Throughout the conveying process, the dustproof plate 6 plays a protective role. Its trapezoidal structure is evenly distributed on the frame 1, effectively blocking external dust and impurities from entering the device, preventing dust from causing wear and malfunctions to components such as the drive unit 2 and roller unit 3, while also avoiding contamination of the corrugated cardboard, ensuring product quality and normal equipment operation.

[0052] The receiving device 8 is responsible for collecting and sorting the corrugated cardboard that is being transported. When the geared motor 801 drives the receiving shaft 802 to rotate, the receiving sprocket 803 rotates accordingly. Through the winding and stretching of the receiving chain 806, the connecting rod 805 moves up and down, thereby realizing the lifting function of the receiving rack 804.

[0053] In addition, the first proximity sensor 7 on the dustproof plate 6 can accurately monitor the position of the corrugated cardboard. When it reaches the preset reversing position, it can promptly trigger the reversing device 4 to perform the reversing operation, ensuring the efficient, accurate and automated operation of the entire conveying, reversing and receiving process, meeting the various needs of the corrugated cardboard production process, and effectively improving production efficiency and product quality.
