Description

Technical Field

[0001] This invention relates to the field of belt alignment technology, and more particularly to a belt alignment system and belt conveyor mechanism. Background Technology

[0002] In belt conveyor mechanisms, belt misalignment is a persistent problem during transmission due to factors such as the parallelism and cylindricity of the conveyor rollers, the parallelism of the mounting base plate, and the straightness of the belt center, as well as the intermittent movement of the belt. Once the belt misaligns, not only will the position of the conveyed product change, affecting the gripping of subsequent processes, but the belt edges will also be prone to wear, ultimately shortening the belt's lifespan.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

Furthermore, those skilled in the art will understand that with technological development and the emergence of new scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0045] In the description of this application, it should be understood that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Furthermore, any terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0046] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] In view of the deficiencies in the existing technology, the applicant, based on years of practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, actively conducted research and innovation in order to create a technology that could solve the deficiencies in the existing technology. After continuous research, design, and repeated prototype production and improvement, the present invention, which has practical value, was finally created.

[0050] Please refer to Figure 1-3 This invention provides a belt misalignment correction system, which includes a belt misalignment sensor 1 and a belt misalignment correction mechanism 2; wherein,

[0051] The belt misalignment sensor 1 is used to sense whether the belt is misaligned and to detect misalignment data when belt misalignment is detected.

[0052] The belt correction mechanism 2 is used to correct the belt deviation based on the deviation data.

[0053] It should be noted that during operation, the belt correction mechanism 2 can be set to correct the belt as soon as the belt misalignment sensor 1 detects belt misalignment, or it can be set to correct the belt only after the belt misalignment sensor 1 detects belt misalignment and the misalignment reaches a set value.

[0054] It is understandable that belt misalignment data refers to the value by which the belt deviates to the left or right in the direction perpendicular to the transmission direction. After the belt misalignment sensor 1 detects this value, the belt correction mechanism 2 can drive the belt to move in the opposite direction of the deviation by this value, thereby completing the belt correction.

[0055] Please refer to this again. Figure 2-3 In this embodiment, the belt correction mechanism 2 includes a base 21, a first correction roller 22, a second correction roller 23, a pressure roller drive assembly 24, and a correction drive assembly 25.

[0056] The pressure roller drive assembly 24 and the correction drive assembly 25 are respectively mounted on the base 21;

[0057] The first correction roller 22 is rotatably mounted on the base 21 and connected to the correction drive assembly 25, and can move in a horizontal direction perpendicular to the conveying direction of the belt under the drive of the correction drive assembly 25.

[0058] The two ends of the second correction roller 23 are rotatably mounted on a corresponding pressure roller drive assembly 24. Under the drive of the pressure roller drive assembly 24, it can tilt and move in a vertical direction perpendicular to the conveying direction of the belt to move closer to or away from the first correction roller 22.

[0059] It should be noted that the first corrective roller 22 and the second corrective roller 23 are responsible for clamping the belt; the pressure roller drive assembly 24 is responsible for driving the second corrective roller 23 to move closer to or away from the first corrective roller 23. When it moves closer, the first corrective roller 22 and the second corrective roller 23 clamp the belt; when it moves away, the first corrective roller 22 and the second corrective roller 23 release the belt; the correction drive assembly 25 is responsible for driving the first corrective roller 22 to move in the opposite direction of the belt deviation in order to correct the clamped belt.

[0060] Please refer to this again. Figure 2-3In this embodiment, the second correction roller 23 is located above the first correction roller 22;

[0061] The axial directions of the first corrective roller 22 and the second corrective roller 23 are both perpendicular to the conveying direction of the belt.

[0062] It should be noted that, since the belt is driven to move in the opposite direction to the deviation by the first correction roller 22, the first correction roller 22 needs to be located below the second correction roller 23. In this way, the belt located between the first correction roller 22 and the second correction roller 23 can be located on the first correction roller 22, so as to increase the contact friction between the first correction roller 22 and the belt, and facilitate the first correction roller 22 to drive the belt to move.

[0063] Please refer to this again. Figure 2-3 In this embodiment, the pressure roller drive assembly 24 includes a ball nut 241, a ball screw 242, a coupling 243, and a correction drive motor 244;

[0064] The first correction roller 22 is connected to the ball nut 241;

[0065] The ball nut 241 is sleeved on the ball screw 242;

[0066] The ball screw 242 is connected to the correction drive motor 244 via the coupling 243.

[0067] It should be noted that after the correction drive motor 244 is started, the correction drive motor 244 drives the ball screw 242 to rotate through the coupling 243. The ball screw 242 drives the ball nut 241 to move left or right in a direction perpendicular to the conveying direction. Thus, the first correction clamping roller 22 can move left or right together with the ball nut 242 in a direction perpendicular to the conveying direction.

[0068] Please refer to this again. Figure 2-3 In this embodiment, the correction drive assembly 25 includes a pressure roller drive cylinder 251 and a rotating plate 252.

[0069] The end of the second correction roller 23 is rotatably mounted on the rotating plate 252;

[0070] One end of the rotating plate 252 is rotatably mounted on the base 21, and the other end is connected to the telescopic end of the pressure roller drive cylinder 251.

[0071] The pressure roller drive cylinder 251 is mounted on the base 21.

[0072] It should be noted that when the extension end of the pressure roller drive cylinder 251 extends, the rotating plate 252 rotates counterclockwise, and the second correction roller 23 moves away from the first correction roller 22. When the extension end of the pressure roller drive cylinder 251 retracts, the rotating plate 252 rotates clockwise, and the second correction roller 23 moves closer to the first correction roller 22.

[0073] Although this application frequently uses terms such as base, first corrective roller, second corrective roller, and pressure roller drive assembly, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.

[0074] The present invention provides a belt deviation correction system, including a belt deviation detection sensor and a belt deviation correction mechanism. The belt deviation sensor senses and detects the belt deviation data, and the belt deviation correction mechanism corrects the belt deviation according to the deviation data. This can correct the belt deviation in a timely manner, ensure that the position of the conveyed products does not change, avoid affecting the gripping of subsequent processes, and reduce the wear on the belt edges, thus extending the belt life and facilitating its widespread application.

[0077] The belt 3 is sleeved on the drive roller 4 and the driven roller 5 and is tensioned;

[0078] The belt alignment system is located between the drive roller 4 and the driven roller 5.

[0079] Please refer to this again. Figure 4-5 In this embodiment, there are at least two driven rollers 5;

[0080] The drive roller 4 is located between the two driven rollers 5;

[0081] There are two belt alignment systems, located on both sides of the drive roller 4.

[0082] It should be noted that the mechanism also includes a tension roller 6 for adjusting the tension of the belt.

[0083] The present invention provides a belt conveyor mechanism, including a belt misalignment detection sensor and a belt correction mechanism. The belt misalignment sensor senses and detects the belt misalignment data, and the belt correction mechanism corrects the belt misalignment based on the misalignment data. This enables timely correction of belt misalignment, ensuring that the position of the conveyed products does not change, avoiding affecting the gripping of subsequent processes. In addition, the belt edge is less prone to wear, extending the belt life and facilitating widespread application.
