[0002] The core function of a belt alignment device is to automatically detect and correct belt misalignment, ensuring that the belt always runs stably on the set centerline or within the allowable range. Through preventative protection, it avoids huge direct and indirect economic losses and is an indispensable key component of modern, high-efficiency, and intelligent conveying systems.

[0003] In existing technologies, the conveyor belts used in electromechanical operations are long, and each belt is equipped with a belt alignment frame every 30 meters. After the belt is adjusted to the appropriate position, the ordinary belt alignment frame is fixed with a steel wire rope. When further adjustment is needed, the steel wire rope needs to be loosened manually. During the operation, it is necessary to manually loosen and tighten the rope with a wrench, and then re-fix it after adjustment. After a long period of use, the rope clips will rust and the screws will be difficult to tighten, resulting in low work efficiency. Therefore, a belt deviation adjustment device that is easy to adjust is designed to overcome the above problems. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-6 This utility model provides an embodiment of a belt misalignment adjustment device, including a bottom support steel pipe 1 and a fixed base plate 2, as well as a swing assembly and a positioning assembly. The fixed base plate 2 is fixedly connected to both sides of the lower end of the bottom support steel pipe 1, and a fixed base 3 is fixedly installed at the upper end of the bottom support steel pipe 1. A main shaft fixing seat 4 is fixedly installed on one side of the fixed base 3, and a connecting shaft 5 is fixedly installed between the two main shaft fixing seats 4. A bushing 6 is fixedly installed on the surface of the connecting shaft 5. The swing assembly is disposed in the bushing 6, and the swing assembly includes a rotating shaft 7 and an inner bearing 8. An inner cylinder 12 is fixedly connected to the end of the rotating shaft 7, and support sleeves 13 are fixedly installed at both ends of the inner cylinder 12. Ball bearings 14 are fixedly installed at the ends of the support sleeves 13. A rubber roller 11 is rotatably connected between ball bearings 14. A fixed frame 15 is fixedly installed on the surface of the support sleeve 13. A side roller 16 is rotatably connected to the end of the fixed frame 15. The rotating shaft 7 is rotatably connected to the inner bearing 8. The positioning component includes a positioning ring 17 and a clamp 22. The positioning component is located on one side of the rubber roller 11. When the belt runs off-center, the clamp 22 disengages from the positioning ring 17 to release the positioning. The position of the side roller 16 is changed according to the direction of belt deviation. The edge of the belt will contact the side roller 16. Friction is generated between the belt and the vertical roller. At this time, the axis of the adjustment device is no longer perpendicular to the belt running direction, but forms a small angle. The lateral component force pointing towards the center will push the belt to move towards the center, thereby correcting the deviation.

[0016] Please see Figure 1 A further solution based on this embodiment is as follows: the rubber roller 11 is composed of a hollow tube and a rubber sleeve. The surface of the rubber sleeve of the rubber roller 11 is provided with staggered anti-slip patterns. The anti-slip patterns provide additional friction, so that the rubber roller 11 can provide a better correction effect when it rotates.

[0017] Please see Figure 5 and Figure 6 A further solution based on this embodiment is as follows: the end of the bushing 6 is fitted with a collar 9, the collar 9 is located at the upper end of the inner bearing 8, and a sealing ring 10 is fitted on the surface of the rotating shaft 7. The collar 9 is used to hold the inner bearing 8 to prevent the inner bearing 8 from vibrating and rotating, and the sealing ring 10 is used to prevent a large amount of lubricant from being lost.

[0018] Please see Figure 4 A further solution based on this embodiment is: the positioning ring 17 is fixedly installed on the surface of the bottom support steel pipe 1, and multiple slots 18 are evenly distributed on the surface of the positioning ring 17, so that the staff can perform multi-angle positioning and facilitate the positioning of the side roller 16.

[0019] Please see Figure 4 A further solution based on this embodiment is as follows: a fixing plate 19 is fixedly connected to the end of the fixing frame 15, and a rotating arm 20 is rotatably connected to the end of the fixing plate 19. One end of the rotating arm 20 is spherical. The rotating arm 20 facilitates the lifting and rotation of the positioning arm 21, so that the chuck 22 disengages from the chuck groove 18 on the surface of the positioning ring 17, and facilitates the subsequent adjustment of the lateral angle.

[0020] Please see Figure 4 A further solution based on this embodiment is as follows: a positioning arm 21 is fixedly connected to the rotating end of the rotating arm 20, and a clamp head 22 is fixedly connected to the lower end of the positioning arm 21. The clamp head 22 is adapted to the clamp slot 18. The clamp head 22 and the clamp slot 18 are used to fix the position of the side roller 16, and the positioning can be released at any time for angle adjustment.

[0021] Please see Figure 4 A further solution based on this embodiment is as follows: a fastening ring 23 is fixedly installed on one side of the fixing plate 19. The fastening ring 23 is frictionally connected to the rotating end of the rotating arm 20. The fastening ring 23 is frictionally connected to the rotating end of the rotating arm 20 to prevent the clamping head 22 from dislodging from the clamping slot 18 due to equipment vibration.

[0022] Working principle: The inner cylinder 12 is rotatably connected to the connecting shaft 5 via the rotating shaft 7. Therefore, the rubber roller 11, which is rotatably connected to the inner cylinder 12 via the ball bearing 14, can rotate. The side roller 16 is installed on the inner cylinder 12 via the fixing frame 15. When the rubber roller 11 rotates, the side roller 16 will rotate at the same time.

[0023] When the belt runs off-center, pull the rotating arm 20 upwards, causing the positioning arm 21 to rotate upwards. The clamp 22 at the lower end of the positioning arm 21 disengages from the groove 18 on the surface of the positioning ring 17. Pull the rotating arm 20 laterally according to the direction of belt deviation, causing the side roller 16 to change position. The edge of the belt will contact the side roller 16, generating friction between the belt and the vertical roller. At this time, the axis of the adjustment device is no longer perpendicular to the belt running direction, but forms a small angle. At this time, the linear velocity direction of the adjustment device can be decomposed into two directions: one along the belt running direction and the other pointing towards the center of the belt. This lateral component pointing towards the center will push the belt to move towards the center, thereby correcting the deviation. When the belt returns to the center position and no longer contacts the side roller 16, the friction disappears. Then, adjust the rubber roller 11 back to the neutral position and lower the rotating arm 20, so that the clamp 22 re-engages and fixes itself with the positioning ring 17.

[0024] The oscillating assembly includes a rotating shaft 7 and an inner bearing 8. The rotating shaft 7 rotates at the inner bearing 8, thereby oscillating the side roller 16 for adjustment. The collar 9 is used to lock the inner bearing 8 to prevent the inner bearing 8 from vibrating and rotating. The sealing ring 10 is used to prevent excessive loss of lubricating fluid.

[0025] The fastening ring 23 is frictionally connected to the rotating end of the rotating arm 20 to prevent the chuck 22 from dislodging from the chuck 18 due to equipment vibration.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
