[0002] In industrial production, multiple transport lines often work together. The transport lines of different processes may have different operating parameters due to process requirements, resulting in differences in transport speeds. At the same time, there are unavoidable systematic errors in the installation position and transport surface height of different transport lines. Traditional manual transfer methods are inefficient and prone to human error. Furthermore, in the transportation of some hazardous chemicals, manual transfer methods can lead to workers coming into direct contact with hazardous chemicals, thereby harming their health. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a transfer device for two transport lines, which can improve transfer efficiency, reduce labor costs, and at the same time, can accurately control the transfer process, accurately transfer materials on two transport lines with different transport speeds, reduce the risk of material damage and loss, and can transport dangerous goods, avoiding direct contact between workers and dangerous goods, and ensuring the personal safety of workers.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a transfer device for between two transport lines, comprising a floating conveyor belt, a floating transmission belt support, and a fixed support. The floating conveyor belt is mounted on the floating transmission belt support, which is equipped with a conveyor belt drive device for driving the floating conveyor belt to perform a conveying action. The floating transmission belt support is slidably mounted on a guide structure of the fixed support, and the extension direction of the guide structure is consistent with the transmission direction of the floating conveyor belt. A drive chain is mounted on the fixed support via a drive sprocket and a driven sprocket, and the floating transmission belt support is partially connected to the upper section of the drive chain via a synchronization plate.

[0005] Furthermore, the guiding structure includes two guide rails, several roller brackets, and several rolling wheels; the two guide rails are arranged at the upper end of the fixed support along the transmission direction of the floating conveyor belt; each rolling wheel is evenly distributed on both sides of the floating conveyor belt bracket along the transmission direction of the floating conveyor belt, and each rolling wheel is installed at both ends of the floating conveyor belt bracket near the fixed support along the transmission direction of the floating conveyor belt through the roller brackets, and each rolling wheel rolls in its corresponding guide rail.

[0006] Furthermore, both guide rails include an upper plate, a lower plate, and a side plate. The lower plate is fixed on both sides of the upper end of the fixed support along the length direction. The upper plate is parallel to and spaced apart from the lower plate above the upper plate. The side plate is connected between the upper plate and the lower plate. The upper plate, the lower plate, and the side plate together form a lateral guide groove, and the openings of the lateral guide grooves of the two rails are oriented towards each other.

[0007] Furthermore, each rolling wheel connected to the floating conveyor belt support via the roller support is rolled in its corresponding side guide groove, and each rolling wheel is rolled in contact with the lower plate of its corresponding guide rail, and each rolling wheel is in clearance contact with the upper plate of its corresponding guide rail.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figures 1-3 As shown, a transfer device for between two transport lines includes a floating conveyor belt 4, a floating transmission belt support 15, and a fixed support 12. The floating conveyor belt 4 is mounted on the floating transmission belt support 15. Both ends of the floating transmission belt support 15 are equipped with transmission wheels for driving the floating conveyor belt 4. The floating conveyor belt 4 is simultaneously wrapped around both transmission wheels. A conveyor belt drive device 8 for driving the floating conveyor belt 4 is mounted on the floating transmission belt support 15. The conveyor belt drive device 8 is located on the side of the floating conveyor belt support 15 away from the floating conveyor belt 4. The floating transmission belt support 15 is slidably mounted on a guide structure 6 of the fixed support 12. The extension direction of the guide structure 6 is consistent with the transmission direction of the floating conveyor belt 4. The fixed support 12... A sprocket drive motor 17 is provided at one end of the fixed support 12. A drive sprocket 18 is coaxially mounted on the drive shaft of the sprocket drive motor 17. A driven sprocket 21 is mounted on the fixed support 12 away from the sprocket drive motor 17 via a sprocket bracket. A drive chain 19 is mounted on the fixed support 12 via the drive sprocket 18 and the driven sprocket 21. The drive chain 19 is simultaneously wrapped around the drive sprocket 18 and the driven sprocket 21. A synchronization plate 9 is provided on the side of the conveyor belt drive device 8 away from the floating conveyor belt 4. The floating transmission belt bracket 15 is partially connected to the upper section of the drive chain 19 via the synchronization plate 9. When the sprocket drive motor 17 drives the drive sprocket 18 to rotate, the drive chain 19 drives the floating transmission belt bracket 15 to slide relative to the fixed support 12 via the synchronization plate 9.

[0017] The guide structure 6 includes two guide rails 14, several roller brackets 16, and several rolling wheels 7. The two guide rails 14 are arranged at the upper end of the fixed support 12 along the transmission direction of the floating conveyor belt 4. The rolling wheels 7 are evenly distributed on both sides of the floating conveyor belt support 15 along the transmission direction of the floating conveyor belt 4. Each rolling wheel 7 is installed at both ends of the floating conveyor belt support 15 near the fixed support 12 along the transmission direction of the floating conveyor belt 4 via the roller brackets 16. Each rolling wheel 7 rolls in its corresponding guide rail 14. When the drive chain 19 drives the floating conveyor belt support 15 to slide relative to the fixed support 12 through the synchronization plate 9, the rolling engagement between each rolling wheel 7 and its corresponding guide rail 14 can guide the sliding of the floating conveyor belt support 15 relative to the fixed support 12.

[0018] like Figure 4As shown, both guide rails 14 include an upper plate 13, a lower plate 11, and a side plate 10. The upper plate 13, lower plate 11, and side plate 10 are integrally formed. The lower plate 11 is fixed to both sides along the length direction at the upper end of the fixed support 12. The upper plate 13 is parallel to and spaced apart from the lower plate 11 above the upper plate 13. The side plate 10 is connected between the upper plate 13 and the lower plate 11. The upper plate 13, lower plate 11, and side plate 10 together form a lateral guide groove 20. The openings of the lateral guide grooves 20 of the two rails 14 are oriented towards each other. The lateral guide grooves 20 can constrain the rolling wheels 7 and prevent the rolling wheels 7 from shifting when rolling with the guide rails 14.

[0019] Each rolling wheel 7 connected to the floating conveyor belt support 15 via the rolling wheel support 16 rolls in its corresponding side guide groove 20, and each rolling wheel 7 rolls in contact with the lower plate 11 of its corresponding guide rail 14. Each rolling wheel 7 also has a clearance fit with the upper plate of its corresponding guide rail 14. This prevents the rolling wheel 7 or the rolling wheel support 16 from contacting the upper plate 13 during the rolling contact with the lower plate 11, which would interfere with the rolling of the rolling wheel 7 and prevent the floating conveyor belt support 15 from continuing to slide relative to the fixed support 12.

[0020] It also includes a first conveyor belt 2 and a second conveyor belt 3, both of which are on a conveyor belt frame. The first conveyor belt 2 and the second conveyor belt 3 have the same transmission direction and are spaced apart. The fixed support 12 is disposed between the first conveyor belt 2 and the second conveyor belt 3. The sliding cooperation between the floating conveyor belt bracket 15 and the fixed support 12 allows the floating conveyor belt 4 to dock with either the first conveyor belt 2 or the second conveyor belt 3 individually, so that the material on the first conveyor belt 2 can be transferred to the second conveyor belt 3 via the floating conveyor belt 4.

[0021] In practical applications, the conveying surfaces of the first conveyor belt 2 and the second conveyor belt 3 are not necessarily on the same horizontal plane, but have a small height difference. Therefore, in order to smoothly transfer the material on the first conveyor belt 2 to the second conveyor belt 3, a common method is to synchronously tilt the fixed support 12, guide rail 14, floating conveyor belt 4, floating conveyor belt support 15, and drive chain 19. However, after the drive chain 19 and fixed support 12 are tilted, the axis of the driving sprocket 18 and the axis of the driven sprocket 21 are not on the same horizontal plane. The non-parallelism of the axes of the driving sprocket 18 and the driven sprocket 21 will disrupt the synchronization of the transmission, causing vibration and impact, and reducing the smoothness of the transmission. At the same time, when the tilted drive chain 19 connects the floating conveyor belt support 15 and the floating guide rail 14, the floating conveyor belt 4, the floating conveyor belt support 15, and the driving sprocket 3 via the synchronization plate 9, the material on the first conveyor belt 2 will be transferred to the second conveyor belt 3. When the moving conveyor belt 4 and the material are transferred together from the lower end to the upper end of the fixed support 12, the chain segment of the drive chain 19 near the upper end of the fixed support 12 not only needs to overcome the forces generated by the floating conveyor belt support 15, the floating conveyor belt 4 and the material along the inclined direction during the transfer process, but also needs to provide sufficient tension for the transfer process. Furthermore, when the inclined drive chain 19 transfers the floating conveyor belt support 15, the floating conveyor belt 4 and the material together from the upper end to the lower end of the fixed support 12 through the synchronization plate 9, the chain segment of the drive chain 19 near the upper end of the fixed support 12 also needs to overcome the forces generated by the floating conveyor belt support 15, the floating conveyor belt 4 and the material along the inclined direction during the transfer process. Therefore, during the transfer process, the drive chain 19 is subjected to uneven force when meshing with the driving sprocket 18 or the driven sprocket 21, which aggravates the wear of the drive chain 19, the driving sprocket 18 and the driven sprocket 21.

[0022] like Figure 1 and 2As shown, in this utility model, when the conveying surfaces of the first conveyor belt 2 and the second conveyor belt 3 are not on the same horizontal plane, in order to ensure that the material on the first conveyor belt 2 can be smoothly transferred to the second conveyor belt 3, the fixed support 12 is always set parallel to the ground, thereby ensuring that the axis of the driving sprocket 18 and the axis of the driven sprocket 21 are always in the same horizontal plane, thereby ensuring that the extension direction of the drive chain 19 is always horizontal; when the two guide rails 14 are installed on the fixed support 12, the two guide rails 14 are set at an angle to the ground, so the floating conveyor belt 4, the floating conveyor belt support 15, and the synchronization plate 9 are also set at an angle to the ground and parallel to the two guide rails 14; the synchronization plate 9 has two inclined adjustment grooves 5, and the two adjustment grooves 5 are symmetrically arranged, the distance between the lower ends of each adjustment groove 5 is greater than the distance between the higher ends of each adjustment groove 5, and the two ends of the drive chain 19 are respectively connected to the two adjustment grooves 5; the drive chain 19, through the synchronization plate 9, connects the floating conveyor belt support 15, the floating conveyor belt 4, and the... During the process of material being transferred from the lower end to the upper end of the guide rail 14, the synchronization plate 9 rises as the height of the guide rail 14 increases, causing the two ends of the drive chain 19 to slide in the two adjustment grooves 5 respectively. The sliding direction is from the higher end of the inclined adjustment groove 5 to the lower end of the adjustment groove 5. Since the height difference between the conveying surface of the first conveyor belt 2 and the conveying surface of the second conveyor belt 3 is small, the sliding adjustment between the two ends of the drive chain 19 and the two adjustment grooves 5 can not only compensate for the height of the drive chain 19, but also increase the distance between the two ends of the drive chain 19, thereby preventing the drive chain 19 from breaking during the transfer process. Furthermore, an elastic tightening device is provided between the two ends of the drive chain 19. The elastic tightening device is an elastic element such as an elastic rope. The two ends of the elastic tightening device are respectively connected to the two ends of the drive chain 19. Under the elastic force of the elastic tightening device, the two ends of the drive chain 19 always tend to move closer to each other, thereby ensuring that the drive chain 19 is always taut, whether the synchronization plate 9 is located at the lower end of the guide rail 14 or the lower end of the guide rail 14.

[0023] like Figure 2As shown, the fixed support 12 is also equipped with a first photoelectric switch 24 and a second photoelectric switch 23, both of which are located below the synchronization plate 9. Both the first and second photoelectric switches 24 and 23 are electrically connected to the sprocket drive motor 17. During the horizontal sliding of the floating transmission belt bracket 15 relative to the fixed support 12, when the synchronization plate 9 moves above the first photoelectric switch 24 under the drive of the drive chain 19, the photoelectric signal of the first photoelectric switch 24 is blocked by the synchronization plate 9. The first photoelectric switch 24 then controls the sprocket drive motor 17. 7. Stop operation, thereby stopping the floating conveyor belt support 15 at the docking position of the floating conveyor belt 4 and the first conveyor belt 2, so that the material on the first conveyor belt 2 can be transferred to the floating conveyor belt 4; when the synchronization plate 9 moves above the second photoelectric switch 23 under the drive of the drive chain 19, the photoelectric signal of the second photoelectric switch 23 is blocked by the synchronization plate 9, and the second photoelectric switch 23 controls the sprocket drive motor 17 to stop operation, thereby stopping the floating conveyor belt support 15 at the docking position of the floating conveyor belt 4 and the second conveyor belt 3, so that the material on the floating conveyor belt 4 can be transferred to the second conveyor belt 3.

[0024] The fixed support 12 is also equipped with a first emergency stop switch 25 and a second emergency stop switch 22. The first emergency stop switch 25 and the second emergency stop switch 22 are located on opposite sides of the first photoelectric switch 24 and the second photoelectric switch 23, respectively. The emergency stop buttons of both the first emergency stop switch 25 and the second emergency stop switch 22 are higher than the plane of the synchronization plate 9. During the movement of the floating transmission belt support 15 towards the first conveyor belt 2 via the synchronization plate 9 and the drive chain 19, if the synchronization plate 9 moves above the first photoelectric switch 24, and the sprocket drive motor 17 does not stop running due to a malfunction of the first photoelectric switch 24, the end of the synchronization plate 9 closest to the first emergency stop switch 25 presses against the emergency stop button of the first emergency stop switch 25, causing the first emergency stop switch 25 to cut off immediately. The power supply to the sprocket drive motor 17 is cut off, preventing the floating transmission belt bracket 15 from continuing to slide relative to the fixed support 12, thus avoiding a collision between the floating transmission belt bracket 15 and the first conveyor belt 2. During the movement of the floating transmission belt bracket 15 towards the second conveyor belt 3 via the synchronous plate 9 and the drive chain 19, if the synchronous plate 9 moves above the second photoelectric switch 23, and the second photoelectric switch 23 malfunctions, causing the sprocket drive motor 17 to continue running, the end of the synchronous plate 9 near the second emergency stop switch 22 presses against the emergency stop button of the second emergency stop switch 22. The second emergency stop switch 22 then immediately cuts off the power supply to the sprocket drive motor 17, preventing the floating transmission belt bracket 15 from continuing to slide relative to the fixed support 12, thus avoiding a collision between the floating transmission belt bracket 15 and the second conveyor belt 3.

[0025] A transfer method for a transfer device between two transport lines:

[0026] Step 1: Start the sprocket drive motor 17 to make the drive sprocket 18 rotate in the forward direction, so that the floating transmission belt support 15 slides relative to the fixed support 12 towards the first conveyor belt 2 under the drive of the drive chain 19.

[0027] Step 2: When the synchronization plate 9 moves above the first photoelectric switch 24, the first photoelectric switch 24 controls the sprocket drive motor 17 to stop running, thereby positioning the floating transmission belt bracket 15 at the position where the floating conveyor belt 4 docks with the first conveyor belt 2;

[0028] Step 3: In the state of Step 2, simultaneously control the first conveyor belt 2 and the floating conveyor belt 4 to drive, so that the material on the first conveyor belt 2 is transferred to the floating conveyor belt 4;

[0029] Step 4: In the state of step 3, pause the continued transmission of the floating conveyor belt 4 and restart the sprocket drive motor 17, so that the drive sprocket 18 rotates in the opposite direction, thereby causing the floating transmission belt support 15 to slide relative to the fixed support 12 towards the second conveyor belt 3 under the drive of the drive chain 19.

[0030] Step 5: In the state of Step 4, when the synchronization plate 9 moves above the second photoelectric switch 23, the second photoelectric switch 23 controls the sprocket drive motor 17 to stop running, thereby positioning the floating transmission belt bracket 15 at the position where the floating conveyor belt 4 and the second conveyor belt 3 dock.

[0031] Step Six: In the state of Step Five, simultaneously control the second conveyor belt 3 and the floating conveyor belt 4 to drive, so that the material on the floating conveyor belt 4 is transferred to the second conveyor belt 3.

[0032] Step 7: By continuously repeating steps 1 to 6, the material transfer between the first conveyor belt 2 and the second conveyor belt 3 can be completed without interruption.

[0033] The above are the preferred embodiments described in this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
