Description

Technical Field

[0001] This utility model relates to the field of belt alignment technology, and in particular to a belt offset roller adjuster. Background Technology

[0002] In industrial production, belt conveyors are widely used in mining, chemical, and grain processing industries as a high-efficiency and continuous material conveying equipment. Their working principle is simple: the belt is driven by a drive device to transport materials from one end to the other. They have advantages such as large conveying capacity, strong adaptability, and stable operation. However, as the service time increases, belt conveyors often experience belt misalignment, which not only affects the operating efficiency of the production line but may also damage the equipment and even cause safety accidents.

[0003] There are various reasons for belt misalignment, mainly including insufficient belt tension, improper idler installation position, uneven material distribution, and belt aging. When belt misalignment is severe, it may rub or collide with other parts of the equipment, causing belt wear, tearing, or even breakage. At the same time, belt misalignment may also cause excessive pressure on components such as idlers, resulting in damage or deformation of these components. When belt misalignment occurs, the material conveyed at the top of the belt is prone to detaching from the belt, especially bulk materials such as salt and coal powder. Once these materials detach from the belt, it will not only cause waste of raw materials, but may also fall into the equipment, causing wear or blockage. In severe cases, it may even lead to equipment shutdown for maintenance, resulting in economic losses for the enterprise. Utility Model Content

[0004] The purpose of this invention is to provide a belt offset roller adjuster to solve the problems that belt offset may cause friction or collision with other parts of the equipment, resulting in belt wear, tearing or even breakage.

[0005] The belt offset roller adjuster provided by this utility model adopts the following technical solution: A belt offset roller adjuster is installed inside a belt, which is mounted inside a conveyor frame. The adjuster includes an adjusting assembly, which includes an adjusting frame that passes through the belt and is fixed to the conveyor frame. Two sliders for moving closer to or further apart are slidably installed inside the adjusting frame. The two sliders are driven to move by a first drive unit. A sliding hole is provided on the adjusting frame along its length. A long plate that slides through the sliding hole is fixed to the slider. The long plate is perpendicular to a bidirectional lead screw. A rotating rod is rotatably connected to the outer side of the end of the long plate away from the slider. The roller is perpendicular to the rotating rod. A support plate is fixed to the end of the rotating rod. Multiple rollers are rotatably mounted side by side on the support plate. The rotating rod is driven to rotate by a second drive unit.

[0006] By adopting the above technical solution, the belt misalignment roller adjuster uses two sliders that can move closer to or further away from each other. These sliders drive the roller to move closer to or further away from the side of the belt, guiding the belt's side. This adjustment method not only ensures that the roller closely fits the belt edge, effectively correcting belt misalignment, but also avoids the problems of over-adjustment or under-adjustment that may occur in traditional adjustment methods. The rotating rod can drive the roller to rotate, maintaining a perpendicular position to the belt when correction is needed for easy correction. After correction, the roller can remain parallel to the belt and be stored inside the belt, without affecting the conveyor's material transport. It is flexible, stable, and reliable in use. This structure has dynamic adaptability, allowing real-time adjustment of the roller position according to the belt conveyor's operating status and material transport conditions. This device ensures stable operation of the belt conveyor and stable material transport speed, improving production efficiency, reducing material waste, and guaranteeing product quality.

[0007] Preferably, the first drive unit includes a bidirectional lead screw rotatably connected to the adjustment frame, the length direction of the bidirectional lead screw being perpendicular to the length direction of the conveyor frame, two sliders being threadedly mounted on the bidirectional lead screw, and a servo motor being coaxially connected to one end of the bidirectional lead screw, the servo motor being fixedly mounted on the outside of the conveyor frame.

[0008] Preferably, the second drive unit includes a gear rotatably mounted on the inner side of the long plate, the gear being coaxially fixed to the rotating rod, a toothed plate that meshes with the gear being slidably mounted on the inner side of the long plate, the toothed plate moving in the same direction as the length of the long plate, and an electric push rod mounted on the inner side of the long plate being connected to the end of the toothed plate.

[0016] The following combination Figures 1-4 This utility model will be further described in detail. An embodiment of this utility model discloses a belt offset roller adjuster, which includes: Conveyor frame 1, with a belt 11 installed inside.

[0017] Adjustment component 2 is located inside the conveyor frame 1. Adjustment component 2 includes an adjustment frame 21 that passes through and is fixed within the internal area of ​​the belt 11. A bidirectional lead screw 22 is arranged along the length of the adjustment frame 21. The bidirectional lead screw 22 is rotatably connected to the end walls of the adjustment frame 21 via bearings. Two sliders 23 are threadedly connected to the outer side of the bidirectional lead screw 22. The sliders 23 slide against the inner wall of the adjustment frame 21. A servo motor 24 is located at one end of the adjustment frame 21. The servo motor 24 is mounted on the outer side of the conveyor frame 1 via a mounting bracket. The output end of the servo motor 24 is coaxially connected to the bidirectional lead screw 22 via a coupling. The bidirectional lead screw 22 and the servo motor 24 form the first driving unit that drives the two sliders 23 to move closer or further apart.

[0018] A long plate 25 is fixedly installed on one side of the slider 23. The long plate 25 is perpendicular to the bidirectional lead screw 22. A sliding hole is opened on the side wall of the adjustment frame 21 along the length direction. The long plate 25 slides through the sliding hole. A rotating rod 26 is rotatably installed on the outer side of the long plate 25 away from the slider 23 through a bearing. The rotating rod 26 is perpendicular to the long plate 25. As can be seen from the above, due to the action of the bidirectional lead screw 22, when the servo motor 24 drives the bidirectional lead screw 22 to rotate, the two sliders 23 will move towards or away from each other inside the adjustment frame 21. In turn, the long plate 25 drives the two rotating rods 26 to move closer or further away from each other.

[0019] A support plate 27 is fixedly installed on the end of the rotating rod 26 away from the long plate 25. Multiple rollers 28 are rotatably mounted on the support plate 27 through bearings. The rollers 28 are perpendicular to the support plate 27. The connection point between the rollers 28 and the support plate 27 is located in the middle of the rollers 28. A gear 29 is rotatably mounted on the inner side of the long plate 25. The gear 29 is coaxially fixed to the rotating rod 26. A toothed plate 210 is slidably mounted on the side of the long plate 25 near the gear 29. The toothed plate 210 meshes with the gear 29. The moving direction of the toothed plate 210 is the same as the length direction of the long plate 25. An electric push rod 211 is fixedly installed on the side of the long plate 25 near the toothed plate 210. The output end of the electric push rod 211 is fixedly connected to one end of the toothed plate 210. The gear 29, the toothed plate 210 and the electric push rod 211 form the second drive unit that drives the rotating rod 26 to rotate.

[0020] As described above, roller 28 is used to adhere to the side of belt 11 and push belt 11 closer to the center position during belt 11 operation, thereby correcting belt 11 deviation. Gear 29, driven by toothed plate 210, drives rotating rod 26 to rotate, which in turn drives roller 28 to rotate. This structure allows adjustment of the direction of roller 28, enabling switching between working and non-working states. During operation, roller 28 needs to be perpendicular to belt 11 to move belt 11. After operation, roller 28 needs to be parallel to belt 11 and retracted into belt 11 by slider 23, so that roller 28 does not affect the conveying operation of belt 11.

[0021] The implementation principle of the belt offset roller adjuster in this embodiment of the utility model is as follows: When the belt 11 is offset, the servo motor 24 is started to drive the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 drives the two sliders 23 to move away from each other until the roller 28 is exposed from the edge of the belt 11. Then, the electric push rod 211 is started to push the toothed plate 210 to move. The toothed plate 210 drives the gear 29 to rotate. The gear 29 drives the rotating rod 26 to rotate synchronously. The rotating rod 26 drives the roller 28 to rotate 90°, so that the roller 28 is perpendicular to the surface of the belt 11. The position of the roller 28 is finely adjusted by the movement of the slider 23 to ensure that the roller 28 on one side is closely attached to the side of the belt 11 on the same side.

[0022] Next, belt 11 is started to operate normally. Simultaneously, servo motor 24 drives the two sliders 23 to move closer together. Due to the friction generated by the contact between roller 28 and the edge of belt 11, the misaligned belt 11 is slowly pushed back to the center position, achieving automatic correction of belt 11 misalignment. After adjustment, the toothed plate 210 moves again, driving gear 29 to rotate 90° in the opposite direction, restoring roller 28 to a horizontal state. The two sliders 23 continue to move closer together until roller 28 is retracted into belt 11, preventing roller 28 from interfering with the normal transport of belt 11.

[0023] The belt offset roller adjuster of this utility model embodiment sets two sliders 23 inside the adjustment frame 21 that can move closer to or further away from each other. The sliders 23 drive the roller 28 to move, so that the roller 28 moves closer to or further away from the side of the belt 11, thus guiding the side of the belt 11. This adjustment method not only ensures that the roller 28 can fit tightly against the edge of the belt 11 and effectively correct the belt offset, but also avoids the problems of over-adjustment or under-adjustment that may occur in traditional adjustment methods.

[0024] The rotating rod 26 can drive the roller 28 to rotate. When correction is needed, it can be kept perpendicular to the belt 11 for easy correction. After correction, the roller 28 can be kept parallel to the belt 11 and stored inside the belt 11 without affecting the material conveying of the belt 11. It is flexible, stable and reliable in use. This structure has dynamic adaptability and can adjust the position of the roller 28 in real time according to the operating status of the belt conveyor and the material conveying situation.

[0025] When belt 11 deviates, the position of roller 28 can be quickly adjusted to ensure that belt 11 remains on the correct running track. This invention can ensure the stable operation of belt conveyor and the stability of material conveying speed, which can not only improve production efficiency, but also reduce material waste and ensure product quality.

[0026] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
