Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to a conveyor belt deviation correction device. Background Technology

[0002] Conveyor belts are typically driven by two conveyor rollers. One conveyor roller is usually driven by a motor, while the other conveyor roller is mainly responsible for tensioning the conveyor belt. To prevent the conveyor belt from deviating, two limit rings are usually installed on the outside of the conveyor roller. The main function of the limit rings is to restrict the lateral movement of the conveyor belt. When the conveyor belt attempts to deviate due to uneven load, material offset, or other reasons, the limit rings will act as a stop, forcing the conveyor belt back to the correct running track.

[0003] However, when conveying batches of heavy glass bottles, the conveyor belt bears a greater load. Under heavy load, the friction between the conveyor belt and the limiting ring will also increase. Long-term friction will cause wear on the surface of the limiting ring, and may even cause it to break, resulting in the limiting ring losing its limiting effect. This will cause the conveyor belt to deviate from the predetermined track during operation. The deviation of the conveyor belt will cause the glass bottles to tilt or tip over during transportation, increasing the risk of bottle breakage. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a conveyor belt deviation correction device. The purpose is to solve the technical problem that under heavy loads, the friction between the conveyor belt and the limiting ring increases, and long-term friction leads to wear and even breakage of the limiting ring surface, causing it to lose its limiting effect. This results in the conveyor belt deviating from its predetermined trajectory during operation, causing the glass bottles to tilt or tip over during transport, increasing the risk of bottle breakage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A conveyor belt deviation correction device includes a conveyor frame with two conveyor rollers inside. A conveyor belt is fitted around the outside of the conveyor rollers. Limiting rings are provided on both sides of the conveyor rollers to position the conveyor belt between the limiting rings on both sides of the conveyor rollers. Multiple correction base plates are provided on the top of the conveyor frame. A support seat is provided on the top of the correction base plate. A movable rod is slidably connected inside the support seat. One end of the movable rod is provided with a recognition end. A recognition seat is provided on the top of the correction base plate. A distance sensor is provided on one side of the recognition seat, facing the recognition end. A contact rod is provided on the other end of the movable rod, with one end of the contact rod close to one side of the conveyor belt. A movable cylinder is provided on the top of the correction base plate. A correction seat is provided on one end of the movable cylinder. A correction roller is rotatably connected to one side of the correction seat, close to one side of the conveyor belt. A controller connected to the movable cylinder and the distance sensor is provided on the top of the correction base plate.

[0007] When the limiting ring of the conveyor roller is damaged by the conveyor belt, the conveyor belt will deviate. Since one end of the contact rod is close to one side of the conveyor belt, the deviating conveyor belt will drive the contact rod to move. The contact rod drives the movable rod to move, and the movable rod drives the identification end to move towards the distance sensor. After the distance sensor detects that the identification end is close, it sends a proximity signal to the controller. After receiving the signal, the controller controls the movable cylinder to work. The movable cylinder drives the correction roller to contact the conveyor belt and applies an appropriate force to push the conveyor belt back to the center position. This allows the correction roller to temporarily replace the limiting ring to limit the conveyor belt and prevent the glass bottles from tipping over when the conveyor belt deviates.

[0008] Furthermore, in this application, one end of the support base is provided with an installation cavity, and a return spring is provided inside the installation cavity. One end of the return spring is connected to the contact rod. The other end of the support base is provided with a movable groove communicating with the installation cavity. The movable rod passes through the installation cavity, so that the movable rod slides in cooperation with the movable groove.

[0009] When the contact rod moves due to the conveyor belt deviation, the contact rod will drive the movable rod to move, and the movable rod will cause the return spring to be compressed. When the conveyor belt returns to the normal conveying track, the contact rod will disengage from the conveyor belt, and the return spring will drive the movable rod to reset, so that the conveyor belt can be reused the next time it deviates.

[0010] Furthermore, in this application, the mounting cavity has first locking protrusions on both sides, the other end of the reset spring is engaged with the first locking protrusions on both sides of the mounting cavity, the other end of the contact rod has second locking protrusions on both sides, and one end of the reset spring is engaged with the second locking protrusions on both sides of the other end of the contact rod.

[0011] One end of the return spring engages with the second latches on both sides of the other end of the contact rod, and the other end of the return spring engages with the first latches on both sides of the mounting cavity. This ensures that the return spring has stable fixing points both inside the mounting cavity and on the contact rod, preventing unnecessary displacement of the return spring when subjected to force and improving the stability of the entire moving rod.

[0012] Furthermore, in this application, one end of the contact rod is provided with a setting groove, a setting post is threadedly connected in the setting groove, one end of the setting post is provided with a contact head, and the contact head is close to the side of the conveyor belt.

[0013] Furthermore, in this application, one end of the movable cylinder is provided with a movable seat, one end of the movable seat is provided with a mounting groove, a connecting column is inserted into the mounting groove, and the calibration seat is located at one end of the connecting column.

[0014] Furthermore, in this application, a first fixing hole is provided on one side of the movable seat, and a second fixing hole is provided on one side of the connecting column. A fixing bolt is inserted into the first fixing hole, and the fixing bolt is threadedly engaged with the second fixing hole.

[0015] Furthermore, in this application, a stabilizing groove is provided on one side of the calibration seat, a stabilizing bearing is provided inside the stabilizing groove, and a rotating shaft is provided on one side of the calibration roller, the rotating shaft being rotatably connected to the inside of the stabilizing bearing.

[0016] Furthermore, in this application, a limiting ring groove is formed on the outer edge of the correction roller, and the limiting ring groove is located on the side close to the conveyor belt.

[0017] Furthermore, in this application, the bottom of the movable seat is provided with a guide slider, and the top of the correction base plate is provided with a guide groove, and the guide slider slides in cooperation with the guide groove.

[0018] Furthermore, in this application, the stabilizing bearing is a one-way bearing.

[0019] This utility model has the following beneficial effects:

[0020] When the limiting ring of the conveyor roller is damaged by the conveyor belt, the conveyor belt will deviate. Since one end of the contact rod is close to one side of the conveyor belt, the deviating conveyor belt will drive the contact rod to move. The contact rod drives the movable rod to move, and the movable rod drives the identification end to move towards the distance sensor. After the distance sensor detects that the identification end is close, it sends a proximity signal to the controller. After receiving the signal, the controller controls the movable cylinder to work. The movable cylinder drives the correction roller to contact the conveyor belt and applies an appropriate force to push the conveyor belt back to the center position. This allows the correction roller to temporarily replace the limiting ring to limit the conveyor belt and prevent the glass bottles from tipping over when the conveyor belt deviates.

[0034] Reference Figures 1-7 In some specific embodiments, a conveyor belt deviation correction device includes a conveyor frame 1, with two conveyor rollers 3 inside the conveyor frame 1, and a conveyor belt 2 sleeved on the outside of the conveyor rollers 3. Limiting rings 4 are provided on both sides of the conveyor rollers 3, so that the conveyor belt 2 is located between the limiting rings 4 on both sides of the conveyor rollers 3. Multiple correction base plates 5 are provided on the top of the correction base plates 1, and a support seat 9 is provided on the top of the correction base plates 5. A movable rod 14 is slidably connected inside the support seat 9. One end of the movable rod 14 is provided with an identification end 15. An identification seat 7 is provided on the top of the correction base plates 5. A distance sensor 8 is provided on one side of the identification seat 7, facing the identification end 15. A contact rod 13 is provided on the other end of the movable rod 14. One end of the contact rod 13 is close to one side of the conveyor belt 2. A movable cylinder 21 is provided on the top of the correction base plates 5. A correction seat 33 is provided on one end of the movable cylinder 21. A correction roller 30 is rotatably connected to one side of the correction seat 33, and the correction roller 30 is close to one side of the conveyor belt 2. A controller 6 is provided on the top of the correction base plates 5, which is signal-connected to the movable cylinder 21 and the distance sensor 8.

[0035] With the above technical solution, when the limiting ring 4 of the conveyor roller 3 is damaged by the conveyor belt 2, the conveyor belt 2 will deviate. Since one end of the contact rod 13 is close to one side of the conveyor belt 2, the deviating conveyor belt 2 will drive the contact rod 13 to move. The contact rod 13 drives the movable rod 14 to move. The movable rod 14 drives the identification end 15 to move towards the distance sensor 8. After the distance sensor 8 detects that the identification end 15 is close, it sends a proximity signal to the controller 6. After receiving the signal, the controller 6 controls the movable cylinder 21 to work. The movable cylinder 21 drives the correction roller 30 to contact the conveyor belt 2 and applies an appropriate force to push the conveyor belt 2 back to the center position. This allows the correction roller 30 to temporarily replace the limiting ring 4 to limit the conveyor belt 2, preventing the glass bottle from tipping over when the conveyor belt 2 deviates.

[0036] It should be noted that the internal temperature of the movable cylinder 21 will rise due to prolonged extension, as continuous pressure and friction will generate heat. Overheating may damage the cylinder's seals, reduce its performance, or cause malfunction. Therefore, when the conveyor belt 2 deviates, the purpose of the correction roller 30 is to temporarily replace the limit ring 4 to limit the conveyor belt 2, preventing the conveyor belt 2 from suddenly deviating and causing a large number of bottles to fall over, thus avoiding significant losses. After the conveying is completed, the correction roller 30 needs to be reset so that the limit ring 4 of the conveyor roller 3 can be repaired or replaced.

[0037] Reference Figures 3-7 In some specific embodiments, one end of the support base 9 is provided with an installation cavity 10, and a return spring 11 is provided inside the installation cavity 10. One end of the return spring 11 is connected to the contact rod 13. The other end of the support base 9 is provided with a movable groove 20 that communicates with the installation cavity 10. The movable rod 14 passes through the installation cavity 10, so that the movable rod 14 slides with the movable groove 20.

[0038] With the above technical solution, when the contact rod 13 moves due to the deviation of the conveyor belt 2, the contact rod 13 will drive the movable rod 14 to move, and the movable rod 14 will drive the return spring 11 to be compressed; when the conveyor belt 2 returns to the normal conveying trajectory, the contact rod 13 is disengaged from the contact of the conveyor belt 2, and the return spring 11 drives the movable rod 14 to reset, so that the conveyor belt 2 can be reused when it deviates again.

[0039] Reference Figures 6-7 In some specific embodiments, the mounting cavity 10 is provided with first locking protrusions 12 on both sides, and the other end of the reset spring 11 is engaged with the first locking protrusions 12 on both sides of the mounting cavity 10. The other end of the contact rod 13 is provided with second locking protrusions 16 on both sides, and one end of the reset spring 11 is engaged with the second locking protrusions 16 on both sides of the other end of the contact rod 13.

[0040] Through the above technical solution, one end of the return spring 11 is engaged with the second latching protrusions 16 on both sides of the other end of the contact rod 13, and the other end of the return spring 11 is engaged with the first latching protrusions 12 on both sides of the mounting cavity 10, so that the return spring 11 has a stable fixing point in the mounting cavity 10 and on the contact rod 13. This prevents the return spring 11 from undergoing unnecessary displacement when subjected to force and improves the stability of the entire movable rod 14.

[0041] Reference Figures 6-7 In some specific embodiments, a setting groove 17 is provided at one end of the contact rod 13, and a setting post 19 is threadedly connected in the setting groove 17. A contact head 18 is provided at one end of the setting post 19, and the contact head 18 is close to the side of the conveyor belt 2.

[0042] With the above technical solution, when the conveyor belt 2 deviates from the normal track, the contact head 18 will come into contact with it, thereby driving the contact rod 13 and the movable rod 14 to move. However, the contact head 18 is prone to damage due to the continuous friction of the conveyor belt 2 during use. The contact head 18 is easily replaced by the threaded engagement between the setting post 19 of the contact head 18 and the setting groove 17.

[0043] Reference Figures 1-5 In some specific embodiments, one end of the movable cylinder 21 is provided with a movable seat 22, one end of the movable seat 22 is provided with a mounting groove 23, a connecting post 26 is inserted into the mounting groove 23, and a calibration seat 33 is provided at one end of the connecting post 26.

[0044] With the above technical solution, the correction roller 30 is prone to damage during use due to the continuous friction of the conveyor belt 2. When the correction roller 30 is damaged, it can be replaced by inserting the connecting post 26 of the correction seat 33 into the mounting groove 23.

[0045] Reference Figures 2-3 In some specific embodiments, a first fixing hole 24 is provided on one side of the movable seat 22, and a second fixing hole 27 is provided on one side of the connecting column 26. A fixing bolt 25 is inserted into the first fixing hole 24, and the fixing bolt 25 is threadedly engaged with the second fixing hole 27.

[0046] With the above technical solution, when the connecting post 26 of the calibration seat 33 is inserted into the mounting groove 23, the fixing bolt 25 passes through the first fixing hole 24, so that the fixing bolt 25 is threadedly engaged with the second fixing hole 27, thereby facilitating the fixing of the calibration seat 33 and enabling the calibration roller 30 to work stably.

[0047] Reference Figures 1-7In some specific embodiments, a stabilizing groove 28 is provided on one side of the calibration seat 33, and a stabilizing bearing 29 is provided inside the stabilizing groove 28. A rotating shaft 31 is provided on one side of the calibration roller 30, and the rotating shaft 31 is rotatably connected to the inside of the stabilizing bearing 29.

[0048] Through the above technical solution, the stabilizing bearing 29 is installed in the stabilizing groove 28. Its function is to support and guide the movement of the rotating shaft 31. The design of the stabilizing bearing 29 allows the rotating shaft 31 to rotate freely inside it, while reducing the friction and wear of the rotating shaft 31 and improving the service life of the correction roller 30.

[0049] Reference Figure 5 In some specific embodiments, a limiting ring groove 32 is formed on the outer edge of the correction roller 30, and the limiting ring groove 32 is close to the side of the conveyor belt 2.

[0050] With the above technical solution, when the conveyor belt 2 deviates, the limiting ring groove 32 of the correction roller 30 rolls with one side of the conveyor belt 2. The limiting ring groove 32 can effectively restrict the movement of the conveyor belt 2 in the vertical direction and prevent the conveyor belt 2 from jumping up and down due to impact or vibration during operation.

[0051] Reference Figures 3-4 In some specific embodiments, the bottom of the movable seat 22 is provided with a guide slider 35, and the top of the correction base plate 5 is provided with a guide groove 34, and the guide slider 35 and the guide groove 34 slide in cooperation.

[0052] Through the above technical solution, the sliding cooperation between the guide slider 35 and the guide groove 34 ensures that the movable seat 22 can maintain linear motion when moving, avoids lateral offset, and improves the accuracy of correction.

[0053] Reference Figures 3-7 In some specific implementations, the stabilizing bearing 29 is a one-way bearing.

[0054] The above technical solution, through the one-way bearing to prevent reverse rotation, helps to maintain the continuous operation of the correction roller 30 and the conveyor belt 2, thereby improving the efficiency and productivity of the entire conveyor belt 2.
