Description

Technical Field

[0001] This utility model relates to the field of conveyor belt anti-deviation, specifically an anti-deviation limiting device for conveyor belts. Background Technology

[0002] When a conveyor belt transports materials, the uneven force on the top of the belt due to the material's landing point and the force present at that point can lead to belt misalignment.

[0003] In existing technologies, conveyor belt deflection is generally limited by adjusting the tension. However, this method requires constant adjustments during long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a conveyor belt anti-deviation limiting device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveyor belt anti-deviation limiting device, comprising drive rollers located at both ends of the inner wall of the conveyor belt, the two drive rollers being used to tension the inner wall of the conveyor belt, and multiple support rollers equidistantly distributed along the length direction being arranged above and below the inner wall of the conveyor belt, the outer periphery of the upper support rollers contacting the lower part of the inner wall of the conveyor belt, and the outer periphery of the lower support rollers contacting the inner wall of the connecting groove downwards, a first anti-deviation mechanism being arranged on the outer periphery of the support rollers, and a second anti-deviation mechanism being arranged inside the conveyor belt and docking with the first anti-deviation mechanism.

[0006] As a further embodiment of this utility model: the first anti-deviation mechanism includes a limiting ring integrally formed on the support roller and the drive roller, and the outer circumference of the limiting ring is integrally formed with an inwardly recessed limiting groove.

[0007] As a further improvement of this utility model, the inner side of the conveyor belt is provided with a connecting groove that engages with the outer periphery of the limiting ring.

[0008] As a further embodiment of this utility model: the second anti-deviation mechanism includes a fixed rod fixedly installed inside the conveyor belt, the fixed rod being distributed along the width direction of the conveyor belt, and an engagement ring integrally formed on the outer circumference of the fixed rod.

[0009] As a further improvement of this utility model, the engagement ring and the limiting groove are aligned one by one.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a No. 1 anti-deviation mechanism and a No. 2 anti-deviation mechanism, the engagement of the No. 1 anti-deviation mechanism with the limiting groove and the engagement of the No. 2 anti-deviation mechanism with the No. 1 anti-deviation mechanism can effectively limit the conveyor belt and effectively improve the fatigue resistance of the limiting position.

[0013] 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.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a conveyor belt anti-deviation limiting device includes drive rollers 2 located at both ends of the inner wall of the conveyor belt 1. The two drive rollers 2 are used to tension the inner wall of the conveyor belt 1. Multiple support rollers 3 are provided at equal intervals along the length direction above and below the inner wall of the conveyor belt 1. The outer periphery of the multiple support rollers 3 located above contacts the lower part of the inner wall of the conveyor belt 1, and the outer periphery of the multiple support rollers 3 located below contacts the lower part of the inner wall of the conveyor belt 1. A first anti-deviation mechanism is provided on the outer periphery of the support rollers 3, and a second anti-deviation mechanism is provided inside the conveyor belt 1 that is connected to the first anti-deviation mechanism.

[0015] In this embodiment: when conveying materials, a drive motor coaxially connected to one drive roller 2 is started. The drive motor drives the connected drive roller 2 to rotate. The drive roller 2 cooperates with another drive roller 2 to drive the conveyor belt 1 for transmission. At this time, the material falling on the conveyor belt 1 can move with the conveyor belt 1. During the conveying process, the first anti-deviation mechanism and the second anti-deviation mechanism cooperate with each other to limit the current position of the conveyor belt 1, avoid the transmission deviation of the conveyor belt 1, and effectively avoid the cracking phenomenon of the conveyor belt 1 caused by the limiting force during the anti-deviation process.

[0016] Please refer to this carefully. Figure 2 and Figure 3 The first anti-deviation mechanism includes a limiting ring 4 integrally formed on the support roller 3 and the drive roller 2. The outer circumference of the limiting ring 4 is integrally formed with an inwardly recessed limiting groove 5. The inner side of the conveyor belt 1 is provided with a connecting groove 7 that engages with the outer circumference of the limiting ring 4.

[0017] In this embodiment: During the transmission process of the conveyor belt 1, the conveyor belt 1 comes into contact with the surface of the support roller 3. Under the friction force, the support roller 3 rotates accordingly, and the support roller 3 drives the limiting ring 4 to rotate synchronously. The limiting ring 4 always rotates within the connecting groove 7. The limiting ring 4 and the connecting groove 7 cooperate to limit the current position of the conveyor belt 1 once.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The second anti-deviation mechanism includes a fixed rod 6 fixedly installed inside the conveyor belt 1. The fixed rod 6 is distributed along the width direction of the conveyor belt 1. The outer circumference of the fixed rod 6 is integrally formed with an engagement ring 8, which is aligned with the limiting groove 5.

[0019] In this embodiment: during the transmission process of the conveyor belt 1, the conveyor belt 1 can drive multiple fixed rods 6 to drive synchronously, and the fixed rods 6 can drive multiple engagement rings 8 to move synchronously. During the transmission process, the engagement rings 8 continuously misalign and engage with multiple limiting grooves 5 one by one, thus achieving a secondary anti-deviation effect. Furthermore, when the material falling unevenly at the top of the conveyor belt 1, the top of the conveyor belt 1 is subjected to uneven force. Under the limit of the primary and secondary anti-deviation measures, the conveyor belt 1 under this force can avoid deviation. Furthermore, the engagement ring 8 of the secondary anti-deviation mechanism and the limiting groove 5 of the primary anti-deviation mechanism can effectively improve the anti-deviation strength and avoid the stress point being located at the contact position between the connecting groove 7 and the limiting ring 4, which would cause tearing due to prolonged stress at that point.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
