Abstract

This utility model discloses a novel anti-deviation device for tubular belts, relating to the field of tubular belt anti-deviation technology. It includes a tubular belt body with an idler roller installed inside. This utility model achieves efficient and precise locking of the idler roller through multi-component linkage. The movement of the second movable rod drives the swing frame and linkage rod to move, while the transmission frame synchronously transmits force, enabling two fixed rods to independently drive their respective connected locking frames. The locking frames approach the idler roller along a preset trajectory, and the arc-shaped plate contacts the idler roller surface to apply uniform pressure, quickly preventing the idler roller from rotating and avoiding tubular belt deviation and equipment damage.

Simultaneously, the spring provides buffering during the locking process to prevent impact damage to the device, and after locking, the rebound force helps the components reset, preparing for the next operation.

Description

Technical Field

[0001] This utility model relates to the field of tubular belt anti-deviation technology, and in particular to a novel tubular belt anti-deviation device. Background Technology

[0002] The head roll opening roller is the most important auxiliary equipment for the normal unfolding of the tubular belt. If the tubular belt fails to open properly during operation and runs out, and the on-site personnel and program control personnel fail to detect it in time, it will result in serious consequences such as the tubular belt stacking, tearing, or even breaking.

[0003] However, in the existing technology, although several cameras and anti-belt misalignment switches have been added to the relevant areas, many problems still exist in actual operation. Because the tubular belt runs at extremely high speed, even with these monitoring devices, it is impossible to guarantee accurate capture of abnormal situations. In addition, many other operating devices need to be monitored and operated at the same time, and adding extra cameras will also pose an economic burden. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that, due to the extremely high speed of the tubular belt, even with monitoring equipment, it is impossible to accurately capture abnormal situations under high-speed operation. Therefore, a new type of tubular belt anti-deviation device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel tubular belt anti-deviation device, comprising a tubular belt body, an idler roller installed inside the tubular belt body, a limit plate rotatably connected to the outer surfaces of both ends of the idler roller, a locking mechanism provided on one side of the limit plate, and a cylinder provided below the tubular belt body; The locking mechanism includes a support frame, with two locking frames rotatably connected to one side of the top of the support frame. An arc-shaped plate is fixedly connected to each of the two locking frames facing each other. A limit rod is fixedly connected to the bottom side wall of the support frame, and a second movable rod is rotatably connected to the bottom of the support frame. A swing frame is fixedly connected to the top of the second movable rod. A transmission frame is rotatably connected to one end of the swing frame, and a linkage rod is rotatably connected to the other end of the swing frame. A fixed rod is fixedly connected to one end of each of the two locking frames. One of the fixed rods is rotatably connected to the linkage rod, and the other fixed rod is rotatably connected to the transmission frame.

[0006] Preferably, one end of one of the fixing rods is rotatably connected to a connecting sleeve, and one end of the other fixing rod is rotatably connected to a second connecting frame.

[0007] Preferably, a first movable rod is fixedly connected to the top of the second connecting frame, and a spring is sleeved on the outer surface of the first movable rod.

[0008] Preferably, the top of the spring is located inside the connecting sleeve, and a baffle is fixedly connected to one end of the fixing rod.

[0009] Preferably, the idler roller is located between two arc-shaped plates, and a first connecting frame is fixedly connected to both ends of the cylinder.

[0010] Preferably, one end of the first connecting frame is rotatably connected to a connecting rod, and both ends of the connecting rod are fixedly connected to the second movable rod.

[0011] Preferably, one end of the other first connecting bracket is rotatably connected to the external bracket.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, efficient and precise locking of the idler roller is achieved through the linkage of multiple components. The movement of the second movable rod drives the swing frame and the linkage rod to move, while the transmission frame synchronously transmits the force, so that the two fixed rods independently drive their respective connected locking frames. The locking frames move closer to the idler roller along a preset trajectory, and the arc plate contacts the surface of the idler roller to apply uniform pressure, quickly stopping the rotation of the idler roller and avoiding the tubular belt from running off track and equipment damage. The fixed rods also drive the second connecting frame and the connecting sleeve to ensure transmission stability and accuracy. At the same time, the spring provides buffering during the locking process to prevent impact from damaging the device, and after locking is completed, the spring force helps the components to reset, preparing for the next operation.

[0013] 2. In this utility model, rapid correction and protection of the idler roller and tubular belt body are achieved through real-time monitoring and precise linkage. When the tubular belt body deviates and touches the limit plate, the high-sensitivity sensor quickly sends a signal to the control system. The control system immediately activates the cylinder drive, which drives the connecting rod and the second movable rod to swing synchronously. Under the synergistic action of the transmission frame and the linkage rod, the locking frame closes, and the arc plate fits against the outer surface of the idler roller, increasing the friction and quickly stopping the idler roller from rotating, thereby correcting the deviation of the tubular belt and ensuring the stable operation of the conveying system. The system design takes into account both real-time performance and reliability. The sensor responds quickly, and the mechanical components cooperate efficiently, avoiding material loss and equipment damage, and significantly improving conveying efficiency and safety.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figures 1-4 As shown, this utility model provides a novel tubular belt anti-deviation device, including a tubular belt body 1, an idler roller 2 installed on the inner side of the tubular belt body 1, a limit plate 3 rotatably connected to the outer surfaces of both ends of the idler roller 2, a locking mechanism 5 provided on one side of the limit plate 3, and a cylinder 4 provided below the tubular belt body 1. The locking mechanism 5 includes a support frame 51. Two locking frames 52 are rotatably connected to one side of the top of the support frame 51. An arc-shaped plate 521 is fixedly connected to the opposite side of each of the two locking frames 52. A limit rod 511 is fixedly connected to the bottom side wall of the support frame 51. A second movable rod 591 is rotatably connected to the bottom of the support frame 51. A swing frame 59 is fixedly connected to the top of the second movable rod 591. A transmission frame 58 is rotatably connected to one end of the swing frame 59, and a linkage rod 54 is rotatably connected to the other end of the swing frame 59. A fixing rod 53 is fixedly connected to one end of each of the two locking frames 52. One fixing rod 53 is rotatably connected to the linkage rod 54, and the other fixing rod 53 is rotatably connected to the transmission frame 58.

[0019] The specific settings and functions of this embodiment will be described in detail below. When locking the idler roller 2, the entire device achieves efficient and precise operation through the linkage of multiple components. Utilizing the movement of the second movable rod 591, the swing frame 59 begins to swing, driving the linkage rod 54 and the transmission frame 58 to move. The linkage rod 54 drives a fixed rod 53 to move through a connecting mechanism at one end, while the transmission frame 58 transmits force to another fixed rod 53, thereby causing the two fixed rods 53 to synchronously but independently drive their respective connected locking frames 52 to move.

[0020] As the two locking frames 52 move, they simultaneously approach the idler roller 2 along a preset trajectory. The arc-shaped plate 521 at the end of the locking frame 52 gradually approaches the surface of the idler roller 2. The arc-shaped design ensures that it can apply uniform pressure over a large contact area, quickly stopping the idler roller 2 from rotating by friction. This design not only enables the locking process to be completed quickly, but also prevents the continuous rotation of the idler roller 2 from causing deviation of the tubular belt body 1, thus preventing equipment damage and tearing accidents.

[0021] Furthermore, during the locking process, the two fixed rods 53 respectively drive the second connecting frame 561 and the connecting sleeve 55 to move, further achieving stability and precision in the transmission. During this process, the spring 57 on the outer surface of the first movable rod 56 is compressed due to pressure. The design of the spring 57 provides a buffer for the locking system, preventing excessive impact force during locking from damaging the idler roller 2 or the locking device. On the other hand, after locking is completed, the rebound force of the spring 57 assists in the component's reset, preparing it for the next operation.

[0022] Example 2: Figure 3 and Figure 4 As shown, one end of a fixed rod 53 is rotatably connected to a connecting sleeve 55, and the other end of a fixed rod 53 is rotatably connected to a second connecting frame 561. A first movable rod 56 is fixedly connected to the top of the second connecting frame 561, and a spring 57 is sleeved on the outer surface of the first movable rod 56. The top of the spring 57 is located inside the connecting sleeve 55, and a baffle is fixedly connected to one end of the fixed rod 53. The roller 2 is located between two arc-shaped plates 521, and both ends of the cylinder 4 are fixedly connected to first connecting frames 41. One end of one first connecting frame 41 is rotatably connected to a connecting rod 42, and both ends of the connecting rod 42 are fixedly connected to a second movable rod 591. One end of the other first connecting frame 41 is rotatably connected to an external support.

[0023] The overall effect of this embodiment is that, during monitoring, the idler roller 2 is supported by the conveyor bracket to ensure the stability and efficiency of material conveying. During operation, a high-sensitivity sensor is installed on the limit plate 3. When the tubular belt body 1 deviates from its designated path, it will touch the limit plate 3, triggering the sensor to quickly transmit a signal to the control system. After receiving the signal, the control system immediately activates the cylinder 4 for drive.

[0024] The cylinder 4 drives the connecting rod 42 to move through its extension and retraction. When the connecting rod 42 begins to move, its motion is further transmitted to the two second movable rods 591, causing them to swing synchronously. During the swinging process, the second movable rods 591, under the coordinated action of the transmission frame 58 and the linkage rod 54, exert a force on the two locking frames 52, causing them to close synchronously.

[0025] During the closing process, the arc-shaped plates 521 on the two locking frames 52 gradually contact the outer surface of the idler roller 2. Utilizing the curved surface contact characteristics of the arc-shaped plates 521, a stable contact is formed with the idler roller 2, increasing friction and quickly stopping the rotation of the idler roller 2. In this way, the misaligned tubular belt body 1 can be quickly and effectively corrected, while avoiding further damage or deviation of the conveyed material, thereby ensuring the stable operation of the conveying system.

[0026] The entire system design takes into account both real-time performance and reliability. Through the rapid response of sensors and the coordinated operation of mechanical components, it ensures that the idler roller 2 can be stopped quickly in the event of an anomaly, thereby reducing losses and improving the safety and production efficiency of equipment operation.

[0027] The device's operation and working principle are as follows: During monitoring, the idler roller 2 is supported by a conveyor bracket. During operation, sensors mounted on the limit plate 3 detect the running status of the tubular belt body 1. When the tubular belt body 1 deviates and touches the limit plate 3, the sensor quickly sends a signal, driving the cylinder 4 to move, which in turn moves the connecting rod 42. As the connecting rod 42 moves, the two second movable rods 591 swing accordingly. To lock the idler roller 2, the movement of the second movable rods 591 causes the swing frame 59 to swing, thereby linking the linkage rod 54 and the transmission frame 58. During this process, the linkage rod 54 drives one fixed rod 53 to move, and the transmission frame 58 transmits the force to the other fixed rod 53. The two fixed rods 53 respectively drive the two locking frames 52 to move. When the locking frames 52 move simultaneously, they drive the arc plate 521 closer to the idler roller 2. The arc plate 521 quickly stops the idler roller 2 from rotating through friction, thus completing the locking and preventing the idler roller 2 from continuing to rotate and causing further deviation or even tearing of the tubular belt body 1.

[0028] During the operation of the locking frame 52, the fixing rod 53 will also drive the second connecting frame 561 and the connecting sleeve 55 to move respectively. At the same time, the spring 57 on the outer surface of the first moving rod 56 will be compressed due to compression.

[0029] After locking is completed, cylinder 4 reverses its movement, relying on the restoring force of spring 57 to achieve rapid reset. The setting of limit rod 511 effectively limits the swing range of second movable rod 591, ensuring that the distance between locking frame 52 and arc plate 521 and idler roller 2 is appropriate, so as to achieve rapid locking in subsequent operations.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
