Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to an intelligent steel strip winding machine based on multi-sensor fusion. Background Technology

[0002] In steel production, strip winding is a crucial step determining product quality and production efficiency. Traditional strip winding machines often rely on single sensors (such as laser rangefinders or pressure sensors) for winding parameter control, making it difficult to handle dynamic changes under complex working conditions. These include tension fluctuations in strips of varying thicknesses and edge misalignment during winding, leading to poor coil shape, material waste, and increased equipment failure rates. As the steel industry moves towards higher precision and intelligence, the single-sensor capabilities of traditional equipment can no longer meet the demands of modern production lines for real-time performance, robustness, and adaptability. Intelligent strip winding machines based on multi-sensor fusion integrate data from laser rangefinders, pressure sensors, vibration sensors, and other dimensions to achieve precise modeling and dynamic adjustment of the winding process, significantly improving the consistency and stability of strip winding.

[0003] In existing technologies, steel strip coiling aids have achieved significant improvements through multi-sensor technology. For example, some devices use laser rangefinders to monitor the strip position in real time, combined with tension data from pressure sensors, and dynamically adjust the tension of the coiling rollers via a PLC control system, effectively reducing strip deviation and coiling defects. However, some existing coiling aids have weak adaptability to changes in material specifications, making it difficult to quickly switch coiling parameters for steel strips of different thicknesses. Therefore, we provide an intelligent steel strip coiling aid based on multi-sensor fusion to solve these problems. Utility Model Content

[0017] I. This intelligent steel strip winding machine based on multi-sensor fusion utilizes the elastic properties of elastic elements to drive the second connecting plate upward a specified distance when the steel coil passes through the gap between the first and second rotating rollers. An infrared rangefinder measures the distance the second connecting plate has risen and transmits the collected information to a PLC controller.

[0025] 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.

[0026] The servo motor 107 and infrared rangefinder 202 in this utility model are common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: an intelligent steel strip winding machine based on multi-sensor fusion, including a tension adjustment mechanism 1, a PLC controller 3 arranged in front of the tension adjustment mechanism 1, and a thickness measuring mechanism 2 arranged inside the tension adjustment mechanism 1. The thickness measuring mechanism 2 includes a first connecting plate 201, a second connecting plate 207, a second rotating roller 210, and a third rotating roller 211. An infrared rangefinder 202 is fixedly installed on the lower surface of the first connecting plate 201, and two mutually symmetrical sliding cylinders 203 are fixedly connected to the lower surface of the first connecting plate 201. Each of the two sliding cylinders 203 has a sliding cavity 204 at its bottom end. An elastic element 205 is fixedly connected to the inner top wall of the cavity. A sliding rod 206 is fixedly connected to the bottom end of the elastic element 205. The outer surface of the sliding rod 206 is slidably connected to the inner side wall of the cavity 204. The upper surface of the second connecting plate 207 is fixedly connected to the bottom end of the sliding rod 206. Two mutually symmetrical third connecting plates 208 are fixedly connected to the lower surface of the second connecting plate 207. A first rotating roller 209 is fixedly installed on one side of the two third connecting plates 208 that are close to each other. The second rotating roller 210 is located directly below the first rotating roller 209. The third rotating roller 211 is located to the right of the second rotating roller 210 and is on the same horizontal plane as the second rotating roller 210.

[0028] Here, the signal transmission device of the infrared rangefinder 202 establishes a two-way communication connection with the signal receiving device of the PLC controller 3. The material of the elastic element 205 is preferably a spring. The first rotating roller 209, the second rotating roller 210, and the third rotating roller 211 are all common mechanical parts in the prior art, and their structure and model will not be described in detail here.

[0029] By controlling the steel strip to pass through the gap between the first rotating roller 209 and the second rotating roller 210, and then controlling the steel strip to wrap around the bottom of the third rotating roller 211, and through the elastic characteristics of the elastic element 205, the slide bar 206 is driven to slide upward inside the slide cavity 204, while simultaneously driving the first rotating roller 209 to move upward. Depending on the thickness of the steel strip, the first rotating roller 209 is driven to move upward a different distance, while the second connecting plate 207 is driven to move upward a specified distance. Then, the distance the second connecting plate 207 rises is measured by the infrared rangefinder 202. The infrared rangefinder 202 transmits the collected information to the PLC controller 3, and the PLC controller 3 controls the tension adjustment mechanism 1 to adjust the tension of the steel strip. The tension of the tension adjustment mechanism 1 can be quickly adjusted according to the thickness of the steel strip, realizing the purpose of this device to intelligently collect the thickness of the steel strip and adjust the tension of the steel strip in a timely manner.

[0030] The tension adjustment mechanism 1 includes a mounting frame 101. The front of the mounting frame 101 is fixedly connected to the mounting plate of the PLC controller 3. The upper left side of the inner wall of the mounting frame 101 is fixedly connected to the outer surface of the first connecting plate 201. A second rotating roller 210 is fixedly installed on the lower left side of the inner wall of the mounting frame 101. A third rotating roller 211 is fixedly installed on the inner wall of the mounting frame 101. Two symmetrical rotating grooves 102 are opened on the inner wall of the mounting frame 101. A rotating disk 103 is rotatably connected to the inner wall of each of the two rotating grooves 102. Two symmetrical tension rollers 104 are rotatably installed on the side of the two rotating disks 103 that are close to each other. A through hole 105 is opened on the front of the mounting frame 101. A rotating rod 106 is rotatably connected to the inner wall of the through hole 105. The rear end of the rotating rod 106 is fixedly connected to the center position of the front of the front rotating disk 103. A servo motor 107 is fixedly installed on the front of the mounting frame 101. The rotating shaft of the servo motor 107 is fixedly connected to the front end of the rotating rod 106.

[0031] Here, the data receiving device of the servo motor 107 establishes a two-way communication connection with the signal transmission device of the PLC controller 3. The tension roller 104 is a common mechanical component in the prior art, and its structure and model will not be described in detail here.

[0032] The PLC controller 3 controls the servo motor 107 to rotate left and right a specified distance, which in turn drives the rotating rod 106 to rotate in the same direction as the servo motor 107 inside the through hole 105, and simultaneously drives the rotating disk 103 to rotate in the same direction as the rotating rod 106 inside the rotating groove 102, and simultaneously drives the two symmetrical tension rollers 104 to rotate left and right around the rotating rod 106 a specified distance. By rotating the two symmetrical tension rollers 104 around the rotating rod 106 a specified distance, the tension of the steel strip can be adjusted to a specified value, thus achieving the purpose of convenient fixed-value adjustment of the steel strip tension of this device.

[0033] Working principle: In use, the steel strip is first controlled to pass through the gap between the first rotating roller 209 and the second rotating roller 210, then controlled to pass around the bottom of the third rotating roller 211, then controlled to pass around the top of the upper tension roller 104, and then controlled to pass around the bottom of the lower tension roller 104. The steel strip is then fixed to the winding reel. Finally, the steel coil is introduced into the front end of the device, and the tension device applies reverse tension to the steel strip as it enters the device. When the steel coil passes through the gap between the first rotating roller 209 and the second rotating roller 210, the elasticity of the elastic element 205 causes the slide bar 206 to slide upward inside the sliding cavity 204, simultaneously moving the first rotating roller 209 upward. Depending on the thickness of the steel strip, the first rotating roller 209 moves upward a different distance, simultaneously moving the second connecting plate 20... 7. Move upward a specified distance, and then measure the distance the second connecting plate 207 rises using an infrared rangefinder 202. The infrared rangefinder 202 transmits the collected information to the PLC controller 3. The PLC controller 3 controls the rotating shaft of the servo motor 107 to rotate left and right a specified distance, thereby driving the rotating rod 106 to rotate in the same direction as the rotating shaft of the servo motor 107 within the through hole 105 for a specified distance. At the same time, it drives the rotating disk 103 to rotate in the same direction as the rotating rod 106 within the rotating groove 102 for a specified distance. Simultaneously, it drives the two mutually symmetrical tension rollers 104 to rotate left and right around the rotating rod 106 for a specified distance. By rotating the two mutually symmetrical tension rollers 104 around the rotating rod 106 for a specified distance, the steel strip tension can be adjusted to a specified value, thus achieving the purpose of convenient fixed-value adjustment of the steel strip tension of this device.
