Description

Technical Field

[0001] This utility model relates to the field of polishing machine belt alignment technology, and in particular to a polishing machine belt alignment mechanism. Background Technology

[0002] In modern industrial production, polishing is a key process in metal processing, wood treatment, and stone surface finishing. Its processing accuracy and equipment stability directly affect product quality and production efficiency. When a polishing machine is running, the abrasive belt, as a core consumable, must maintain a precise running trajectory. However, if the abrasive belt deviates during high-speed movement, it will not only lead to uneven polishing and reduced workpiece surface accuracy, but also cause problems such as abrasive belt wear and breakage, and equipment failure.

[0003] In existing technologies, the belt alignment mechanism of polishing machines mainly achieves belt position adjustment through closed-loop control of sensors and actuators. Its technical principle is typically as follows: photoelectric sensors or ultrasonic sensors monitor the edge position of the belt in real time. When an offset signal is detected, the data is transmitted to a control system such as a PLC or microcontroller. After processing, the system drives actuators such as cylinders and motors, adjusting the angle and position of guide rollers or alignment wheels to change the belt's running direction, thereby achieving alignment.

[0004] However, existing technologies generally suffer from cleaning challenges due to the operating environment of the abrasive belt. During polishing, impurities such as metal shavings, dust, and oil easily adhere to the surface of the guide roller, forming a contaminant layer of uneven thickness. These contaminants alter the surface roughness of the roller, causing unstable friction between the abrasive belt and the roller surface, which in turn leads to belt slippage or deviation. When contaminants accumulate to a certain extent, they not only exacerbate wear on the abrasive belt edges but also cause transmission interruptions, forcing equipment shutdown for maintenance and severely impacting production efficiency. Therefore, a belt guidance mechanism for polishing machines is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polishing machine belt correction mechanism, which aims to improve the problem that the correction surface cannot be cleaned in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A belt alignment mechanism for a polishing machine includes an alignment frame, an alignment component on the outer wall of the alignment frame, an alignment wheel rotatably connected to the outer wall of the alignment frame, and a cleaning component on the outer wall of the alignment wheel. The cleaning assembly includes a brush, the outer wall of which is disposed on the outer wall of the alignment wheel. A fixing plate is fixedly connected to the outer wall of the alignment frame. A groove is formed inside the fixing plate. A fixing rod is disposed inside the groove. The bottom of the fixing rod is fixedly connected to the inner wall of the groove. A sliding rod is slidably connected to the inner wall of the fixing rod. A spring is disposed inside the fixing rod. One end of the spring is fixedly connected to the inner wall of the fixing rod. The other end of the spring is fixedly connected to the bottom of the sliding rod. The bottom of the brush is fixedly connected to the top of the sliding rod. As a further description of the above technical solution: The alignment component includes a correction plate, the outer wall of which is disposed on the outer wall of the correction frame, and a slot is provided inside the correction frame; As a further description of the above technical solution: The inner wall of the correction frame is fixedly connected to a slide rail, and the outer wall of the slide rail is slidably connected to a moving block; As a further description of the above technical solution: A connecting block is fixedly connected to the top of the movable block, and the bottom of the correction plate is fixedly connected to the top of the connecting block; As a further description of the above technical solution: A fixing block is fixedly connected to the inner wall of the movable block, and a pressing block is slidably connected to the inner wall of the movable block; As a further description of the above technical solution: The inner wall of the movable block is provided with a second spring. One end of the second spring is fixedly connected to the outer wall of the fixed block, and the other end of the second spring is fixedly connected to the outer wall of the pressing block. As a further description of the above technical solution: The bottom of the pressing block is fixedly connected to a locking block, and the outer wall of the locking block is slidably connected to the inner wall of the locking groove.

[0007] This utility model has the following beneficial effects: In this invention, the alignment roller is cleaned by a brush, and the dust removed by the brush falls into the groove, thus achieving the effect of cleaning the surface of the alignment roller. This prevents impurities such as dust, fibers, and oil from adhering to the surface of the alignment roller, which would form an uneven layer of contaminants, causing changes in the surface roughness of the alignment roller, unstable friction, and potentially causing the sanding belt to slip or run off-track. In severe cases, this could lead to transmission interruption, thereby maintaining a smooth roller surface and increasing the stability of equipment operation.

[0008] In this invention, pressing the pressing block moves the locking block, which then moves out of the slot, thus achieving the effect of aligning the sanding belt. This prevents the sanding belt from easily shifting laterally due to uneven tension, equipment vibration, or installation errors during high-speed operation. If not corrected in time, the accumulated deviation can cause the edge of the sanding belt to rub against equipment components, or even fall off the polishing wheel, leading to machine downtime. This invention adjusts the direction of the sanding belt's movement, controlling the deviation within the allowable range and preventing further deviation. Attached Figure Description

[0011] 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.

[0012] Reference Figures 1-3This utility model provides an embodiment of a polishing machine belt alignment mechanism, including an alignment frame 1. An alignment component is provided on the outer wall of the alignment frame 1. An alignment wheel 2 is rotatably connected to the outer wall of the alignment frame 1. A cleaning component is provided on the outer wall of the alignment wheel 2, including a brush 3. The brush 3 is used to clean metal shavings, dust, and other impurities adhering to the surface of the alignment wheel in real time, thereby preventing contaminants from affecting the contact effect between the belt and the alignment wheel, and avoiding belt misalignment or accelerated wear due to impurity accumulation. The outer wall of the brush 3 is located on the outer wall of the alignment wheel 2. A fixing plate 7 is fixedly connected to the outer wall of the alignment frame 1. A groove 8 is formed inside the fixing plate 7 for collecting... The brush 3 collects the impurities swept away, effectively preventing them from being re-spread or re-adhering to the surface of the alignment wheel 2. A fixing rod 5 is installed inside the groove 8, with its bottom fixedly connected to the inner wall of the groove 8. A sliding rod 4 is slidably connected to the inner wall of the fixing rod 5. A spring 6 is installed inside the fixing rod 5, with one end fixedly connected to the inner wall of the fixing rod 5 and the other end fixedly connected to the bottom of the sliding rod 4. The bottom of the brush 3 is fixedly connected to the top of the sliding rod 4. The sliding rod 4 and the fixing rod 5 work together to slide up and down, thereby providing continuous elastic pressure to the brush 3 in conjunction with the spring 6, ensuring that the brush 3 always adheres to the surface of the alignment wheel 2.

[0013] Reference Figure 1 , Figure 4 and Figure 5The alignment component includes a correction plate 17, which is used to limit the position of the abrasive belt and guide it back to the correct running trajectory, achieving real-time correction of abrasive belt deviation and ensuring polishing accuracy. The outer wall of the correction plate 17 is set on the outer wall of the correction frame 1. The correction frame 1 has slots 9 inside, with multiple slots 9 for fixing the correction plate 17 at different positions, achieving the effect of adapting to abrasive belts of different widths. A slide rail 10 is fixedly connected to the inner wall of the correction frame 1, and a moving block 11 is slidably connected to the outer wall of the slide rail 10. A connecting block 16 is fixedly connected to the top of the moving block 11, and the bottom of the correction plate 17 is fixedly connected to the top of the connecting block 16. The connecting block 16 is used to securely connect the correction plate 17 and the moving block 11. The bottom of the correction plate 17 is fixedly connected to the top of the connecting block 16, so that the correction plate 17 can move synchronously with the moving block 11, achieving flexible adjustment of the position of the correction plate 17. To adapt to the need for correcting different widths of abrasive belts, a fixed block 12 is fixedly connected to the inner wall of the moving block 11, and a pressing block 13 is slidably connected to the inner wall of the moving block 11. A second spring 14 is provided on the inner wall of the moving block 11. One end of the second spring 14 is fixedly connected to the outer wall of the fixed block 12, and the other end of the second spring 14 is fixedly connected to the outer wall of the pressing block 13. A locking block 15 is fixedly connected to the bottom of the pressing block 13, and the outer wall of the locking block 15 is slidably connected to the inner wall of the slot 9. When it is necessary to adjust the position of the correction plate 17, the pressing block 13 is pressed, the second spring 14 is compressed, and the locking block 15 is disengaged from the slot 9. At this time, the moving block 11 can be pushed to move along the slide rail 10. After the adjustment is in place, the pressing block 13 is released, the second spring 14 is reset, and the locking block 15 is re-engaged into the corresponding positioning hole of the slot 9, thereby locking the position of the correction plate 17. This achieves the effect of convenient and quick adjustment of the position of the correction plate 17 and ensures its stability and reliability during operation.

[0014] Working principle: When the polishing machine is running, the brush 3 cleans the surface of the straightening wheel 2. Then, the spring 6 drives the sliding rod 4 to move, which in turn drives the brush 3 to move, so that the brush 3 is in close contact with the surface of the straightening wheel 2. The impurities swept off by the brush 3 fall into the groove 8 for collection, which prevents dust, fibers, oil and other impurities from adhering to the surface of the straightening wheel 2, forming an uneven layer of contaminants, which would change the surface roughness of the straightening wheel, cause unstable friction, and also cause the sanding belt to slip or run off-center, and in severe cases, cause the transmission to be interrupted.

[0015] To prevent severe belt misalignment, the pressing block 13 is pressed first, which compresses the second spring 14. The movement of the pressing block 13 then moves the locking block 15. When the locking block 15 moves out of the slot 9, it releases the limit on the moving block 11. Next, the sliding moving block 11 moves the connecting block 16. Then, the movement of the connecting block 16 moves the correction plate 17. When the correct position is reached, the pressing block 13 is released, and the rebound of the second spring 14 resets the pressing block 13. The reset of the pressing block 13 then moves the locking block 15 into the slot 9, thus limiting the moving block 11. This prevents the belt from easily shifting laterally due to uneven tension, equipment vibration, or installation errors during high-speed operation. If not corrected in time, the accumulated deviation can cause the edge of the belt to rub against equipment parts, or even fall off the polishing wheel, leading to downtime.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
