Description

Technical Field

[0001] This application relates to the field of conveyor equipment technology, and in particular to a real-time forced belt correction device. Background Technology

[0002] In belt conveyor systems, belt misalignment is the core problem leading to material spillage, equipment wear, and even shutdown accidents. Existing belt correction devices mostly rely on passive adjustment (such as friction guide wheels), which have the drawback of slow response: when the belt misalignment is large, it cannot be quickly reset, which can easily cause the belt edge to wear more severely and even lead to shutdown. Some active belt correction structures are complex, require external power to drive, have high maintenance costs, and are prone to failure in harsh environments such as dust and humidity, making them difficult to adapt to the high-intensity operation requirements of heavy industrial scenarios.

[0003] In response to the aforementioned technologies, a real-time forced belt deviation correction device is proposed, which can quickly respond in the early stage of belt deviation, prevent the deviation from escalating, and does not require external power drive. Utility Model Content

[0004] The purpose of this application is to provide a real-time forced belt alignment device to overcome the above-mentioned shortcomings.

[0005] In the first aspect, the real-time forced belt correction device provided in this application adopts the following technical solution: it includes a belt, a guide wheel assembly one, a guide wheel assembly two, and a support roller group. The guide wheel assembly one and the guide wheel assembly two have the same structure and are symmetrically arranged on the left and right sides of the belt support layer of the belt. The support roller group is used to support the bottom of the belt support layer of the belt.

[0006] The guide wheel assembly includes a housing, a guide wheel, a movable frame, and a connecting rod assembly. The movable frame is located on the right side inside the housing, and the guide wheel is installed inside the movable frame. The connecting rod assembly is located on the outside of the movable frame, and a limit rod is fixed to the outer end of the movable frame, with the limit rod penetrating through the housing. The outer end of the movable frame is elastically connected to the housing by a spring, and the spring is fitted around the outside of the limit rod.

[0007] By adopting the above technical solution, the belt offset pushes the guide wheel, the guide wheel drives the movable frame to move synchronously, the movement of the movable frame drives the movable roller to tilt through the linkage assembly, the tilting of the movable roller realizes the belt offset correction, and the guide wheel moves with the belt offset, and the movable roller tilts with the belt offset.

[0008] The support roller assembly includes a support roller, a movable roller one, and a movable roller two. The left and right sides of the support roller are connected to the movable roller one and the movable roller two, respectively. The connecting rod assemblies of the guide wheel assembly one and the guide wheel assembly two are connected to the movable roller one and the movable roller two, respectively. A support shaft is provided at the center of each of the support roller, the movable roller one, and the movable roller two. The support shaft of the support roller is connected to the support shaft of the movable roller one and the movable roller two through a universal coupling. Support bearings are installed on both the left and right sides of the support shaft of the support roller. Bearing seats are fitted on the outside of the support bearings. The bottom end of the bearing seats is fixedly connected to the support frame. The left and right sides of the support frame are fixedly connected to the outer shells of the guide wheel assembly one and the guide wheel assembly two, respectively.

[0009] By adopting the above technical solution, the support roller and the movable roller are connected by a universal coupling, allowing the movable roller to deflect flexibly in the vertical direction while transmitting torque to maintain synchronous rotation.

[0010] Preferably, the linkage assembly includes a rotating rod, a fixed rotating shaft, a sliding groove, a first connecting rotating shaft, a second connecting rotating shaft, a connecting rod, and an adjusting rod assembly. The middle part of the rotating rod is rotatably connected to the fixed rotating shaft. Sliding grooves are provided on both the upper and lower sides of the interior of the rotating rod, and the first connecting rotating shaft and the second connecting rotating shaft are slidably connected in the two sliding grooves, respectively. The first connecting rotating shaft is connected to the movable frame, the second connecting rotating shaft is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is connected to the adjusting rod assembly. The adjusting rod assemblies of the first and second guide wheel assemblies are respectively connected to the first movable roller and the second movable roller. The fixed rotating shaft is fixedly connected to the outer shell.

[0011] By adopting the above technical solution, when the belt deviates and pushes the guide wheel, the connecting shaft slides in the groove, driving the rotating rod to rotate around the fixed rotating shaft, and transmitting the rotation to the movable roller through the connecting rod to achieve the correction action.

[0012] Preferably, the slide grooves are arranged parallel to the rotating rod, and the inner walls of the two slide grooves are respectively in contact with the first connecting shaft and the second connecting shaft.

[0013] By adopting the above technical solution, it is ensured that the rotating shaft slides linearly in the groove without jamming, making the movement of the rotating rod smoother and improving the reliability and durability of the correction action.

[0014] Preferably, the guide wheel is fitted to the edge of the belt support layer of the belt.

[0015] By adopting the above technical solution, the guide wheel directly contacts the edge of the belt, which can detect the belt deviation trend in real time. Once the belt contacts the guide wheel, its lateral displacement is converted into the mechanical movement of the movable frame, triggering the subsequent correction mechanism without the need for additional sensors.

[0016] Preferably, the support roller, movable roller one, and movable roller two are all in contact with the bottom end face of the belt support layer of the belt, and the support roller is centrally located at the bottom of the belt support layer.

[0017] By adopting the above technical solution, the support roller is centrally positioned to support the bottom of the belt, and together with the movable rollers on both sides, they form an adaptive support surface. When the movable roller tilts due to the correction, the support roller remains horizontal, ensuring that the central area of ​​the belt is stably stressed and avoiding local wrinkles or stress concentration in the belt during the correction process.

[0018] Secondly, the real-time forced belt correction device provided in this application adopts the following technical solution: the adjusting rod assembly includes a support block, a connecting block, a support plate and an adjusting screw. The outer sides of the support block and the connecting block are provided with support plates. One end of the adjusting screw is rotatably connected to the support plate through a bearing, and the other end of the adjusting screw passes through another support plate and is threaded. The bottom end of the connecting block is rotatably connected to the connecting rod through a rotating shaft.

[0019] The support blocks of guide wheel assembly one and guide wheel assembly two are respectively connected to the support shafts of movable roller one and movable roller two through bearings.

[0020] By adopting the above technical solution, the adjusting screw can push the connecting block to move through the thread, thereby finely adjusting the initial position of the connecting rod, and then adjusting the initial position of the movable roller to ensure that the movable roller supports the side of the belt support layer.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By having the guide wheel fit against the edge of the belt support layer, the guide wheel can be pushed to generate mechanical displacement when the belt deviates, directly triggering subsequent correction actions. This eliminates the need for electrical components such as sensors, avoids signal delay and environmental interference problems, and achieves real-time correction of the pure mechanical structure. The entire structure adopts a pure mechanical structure with a short transmission link and no need for electrical components.

[0023] 2. The displacement of the guide wheel is synchronously transmitted to the movable roller through the linkage assembly. The tilt angle of the movable roller is linearly related to the belt offset. The correction force is dynamically adjusted with the offset, effectively avoiding over-correction or under-correction. The cooperation between the spring and the limit rod ensures that the movable frame returns to its original position quickly after the belt resets, so that the guide wheel continues to fit against the belt edge, ensuring the continuity and stability of the correction.

[0024] 3. By setting up an adjusting rod assembly, the initial position of the movable roller can be finely adjusted by adjusting the screw, which can adapt to belts of different widths and different load conditions, making it highly versatile. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0039] Example 1: A real-time forced belt alignment device, referring to... Figure 1-4 It includes a belt 1, a guide wheel assembly 1 2, a guide wheel assembly 2 3, and a support roller group 4. The guide wheel assembly 1 2 and the guide wheel assembly 2 3 have the same structure and are symmetrically arranged on the left and right sides of the belt support layer 11 of the belt 1. The support roller group 4 is used to support the bottom of the belt support layer 11 of the belt 1.

[0040] The guide wheel assembly 2 includes a housing 21, a guide wheel 22, a movable frame 23, and a connecting rod assembly 24. The movable frame 23 is located on the right side inside the housing 21. The guide wheel 22 is installed inside the movable frame 23. The connecting rod assembly 24 is located on the outside of the movable frame 23. A limit rod 25 is fixed to the outer end of the movable frame 23 and passes through the housing 21. The outer end of the movable frame 23 is elastically connected to the housing 21 through a spring 26, and the spring 26 is fitted on the outside of the limit rod 25.

[0041] By adopting the above technical solution, the belt 1 deflects and pushes the guide wheel 22, the guide wheel 22 drives the movable frame 23 to move synchronously, the movement of the movable frame 23 drives the movable roller to tilt through the linkage assembly 24, and the tilting of the movable roller realizes the correction of the belt 1, and the guide wheel 22 moves with the offset of the belt 1, and the movable roller tilts with the offset of the belt 1.

[0042] Reference Figure 5-6 The linkage assembly 24 includes a rotating rod 241, a fixed rotating shaft 242, a sliding groove 243, a connecting rotating shaft one 244, a connecting rotating shaft two 245, a connecting rod 246, and an adjusting rod assembly 247. The middle part of the rotating rod 241 is rotatably connected to the fixed rotating shaft 242. Sliding grooves 243 are provided on both the upper and lower sides of the interior of the rotating rod 241, and the two sliding grooves 243 are slidably connected to the connecting rotating shaft one 244 and the connecting rotating shaft two 245, respectively. The connecting rotating shaft one 244 is connected to the movable frame 23. The connecting rotating shaft two 245 is rotatably connected to one end of the connecting rod 246, and the other end of the connecting rod 246 is connected to the adjusting rod assembly 247. The adjusting rod assemblies 247 of the guide wheel assembly one 2 and the guide wheel assembly two 3 are respectively connected to the movable roller one 42 and the movable roller two 43. The fixed rotating shaft 242 is fixedly connected to the outer shell 21.

[0043] By adopting the above technical solution, when the belt 1 deviates and pushes the guide wheel 22, the connecting shaft 244 slides in the groove, driving the rotating rod to rotate around the fixed rotating shaft 242, and transmitting it to the movable roller through the connecting rod 246 to realize the correction action.

[0044] The slide groove 243 is arranged parallel to the rotating rod 241, and the inner walls of the two slide grooves 243 are respectively in contact with the connecting shaft 1 244 and the connecting shaft 245;

[0045] By adopting the above technical solution, it is ensured that the rotating shaft slides linearly in the groove without jamming, making the rotating rod 241 move more smoothly and improving the reliability and durability of the correction action.

[0046] The guide wheel 22 is fitted to the edge of the belt support layer 11 of the belt 1;

[0047] By adopting the above technical solution, the guide wheel 22 directly contacts the edge of the belt 1, which can detect the belt 1 deviation trend in real time. Once the belt contacts the guide wheel 22, its lateral displacement is converted into the mechanical movement of the movable frame 23, triggering the subsequent correction mechanism without the need for additional sensors.

[0048] Support roller 41, movable roller 1 42 and movable roller 2 43 are all in contact with the bottom end face of belt support layer 11 of belt 1, and support roller 41 is centrally located at the bottom of belt support layer 11.

[0049] By adopting the above technical solution, the support roller 41 supports the bottom of the belt 11 in the middle and together with the movable rollers on both sides, it forms an adaptive support surface. When the movable roller tilts due to the correction, the support roller 41 remains horizontal, ensuring that the central area of ​​the belt 1 is stably stressed and avoiding local wrinkles or stress concentration of the belt 1 during the correction process.

[0050] Reference Figure 7 The support roller assembly 4 includes a support roller 41, a movable roller 1 42, and a movable roller 2 43. The left and right sides of the support roller 41 are connected to the movable roller 1 42 and the movable roller 2 43, respectively. The connecting rod assemblies 24 of the guide wheel assembly 1 and the guide wheel assembly 2 are connected to the movable roller 1 42 and the movable roller 2 43, respectively. A support shaft is provided at the center of each of the support roller 41, the movable roller 1 42, and the movable roller 2 43. The support shaft of the support roller 41 is connected to the support shaft of the movable roller 1 42 and the movable roller 2 43 through a universal coupling 44. Support bearings 45 are installed on both the left and right sides of the support shaft of the support roller 41. Bearing seats are fitted on the outside of the support bearings 45. The bottom end of the bearing seats is fixedly connected to the support frame 46. The left and right sides of the support frame 46 are fixedly connected to the outer shell 21 of the guide wheel assembly 1 and the guide wheel assembly 2, respectively.

[0051] By adopting the above technical solution, the support roller 41 and the movable roller are connected by the universal coupling 44, allowing the movable roller to deflect flexibly in the vertical direction, while transmitting torque to maintain synchronous rotation.

[0052] In this embodiment, two sets of rotating rods 241 and connecting rods 246 are used to ensure smooth transmission and support for the support rollers. The rotating rod 241 of the guide wheel assembly 2 is inclined downward from left to right, and the connecting rod 246 is inclined upward from left to right.

[0053] The implementation principle of this application embodiment is as follows:

[0054] When belt 1 deviates to the left during operation, the edge of the belt presses against the left guide wheel 22, pushing the movable frame 23 to move outward. The movable frame 23 is limited by the limit rod 25, causing the movable frame 23 to move outward in parallel. At the same time, the compressed spring 26 stores energy. The outward movement of the movable frame 23 drives the rotating rod 241 to rotate around the fixed rotating shaft 242 through the connecting shaft 1 244. The rotating rod 241 pushes the connecting rod 246 through the connecting shaft 245. The connecting rod 246 pushes the adjusting rod assembly 247 upward. The adjusting rod assembly 247 pushes the movable roller 42 to tilt upward around the universal coupling 44, causing the support layer of belt 1 to generate a centripetal force, forcibly pushing belt 1 back to the center position, realizing the automatic correction of belt 1. It adopts a purely mechanical structure and does not require electrical components.

[0055] The energy stored by the spring 26 is released, which pushes the movable frame 23 to reset, ensuring that the guide wheel 22 continues to fit the edge of the belt. During the belt 1 correction process, the guide wheel 22 resets synchronously with the belt 1, and the movable roller 42 automatically adjusts the tilt angle according to the belt 1 offset.

[0056] Example 2: A real-time forced belt alignment device, referring to... Figure 8 The adjusting rod assembly 247 includes a support block 2471, a connecting block 2472, a support plate 2473, and an adjusting screw 2474. The support block 2471 and the connecting block 2472 are both provided with support plates 2473 on their outer sides. One end of the adjusting screw 2474 is rotatably connected to the support plate 2473 through a bearing, and the other end of the adjusting screw 2474 passes through another support plate 2473 and is threaded. The bottom end of the connecting block 2472 is rotatably connected to the connecting rod 246 through a rotating shaft.

[0057] The support blocks 2471 of guide wheel assembly 1 2 and guide wheel assembly 2 3 are respectively connected to the support shafts of movable roller 1 42 and movable roller 2 43 via bearings;

[0058] The top of the adjusting screw 2474 is equipped with a bolt head. By rotating the bolt head, the adjusting screw 2474 is driven to rotate. The rotation of the adjusting screw 2474 adjusts the distance between the two support plates 2473, thereby adjusting the initial position of the movable roller.

[0059] By adopting the above technical solution, the adjusting screw 2474 pushes the connecting block 2472 to move through the thread, which can finely adjust the initial position of the connecting rod 246, thereby adjusting the initial position of the movable roller and ensuring that the movable roller supports the side of the belt support layer 11 of the belt 1.

[0060] The adjusting screw 2474 is equipped with a locking nut. There are two locking nuts, which are respectively located on the upper and lower sides of the support plate 2473 that is threadedly connected to the adjusting screw 2474, to prevent the adjusting screw 2474 from rotating on its own.

[0061] The implementation principle of this application embodiment is as follows:

[0062] Rotate the adjusting screw 2474, which pushes the connecting block 2472 to move axially through the thread. The connecting block 2472 drives the connecting rod 246 to change the initial angle, thereby adjusting the initial position of the movable roller. Adjust the movable roller to fit against the bottom end face of the belt support layer 11 of the belt 1. After the adjustment is completed, tighten the two locking nuts. When tightening, the two locking nuts fit tightly against the upper and lower sides of the support plate 2473 that is threadedly connected to the adjusting screw 2474.

[0063] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
