Abstract
Description
Technical Field
[0001] This utility model relates to the field of wide-band sander technology, specifically to a wide-band sander with a correction mechanism for rail vehicle parts. Background Technology
[0002] A wide-band sander is a large machine for processing sheet materials. It is often used to perform processes such as sanding, thickness setting, and polishing on sheet materials, making them suitable for various applications.
[0003] In practical use, wide-band sanders are mainly used to polish the surface of boards to keep the surface of the boards flat.
[0004] Therefore, after a wide belt sander has been working for a long time, the sanding belt is prone to gradually loosening, resulting in insufficient tension during the sanding process, which can easily lead to deviation. At the same time, if the sanding belt is subjected to uneven force during the sanding process, it will also cause the sanding belt to deviate, thus affecting the accuracy of the board processing.

[0041] 3. In this utility model, the first correction mechanism facilitates the rotation of the second gear by rotating the first handwheel. Simultaneously, the meshing of the second gear and the third gear drives the third gear and the first bidirectional screw to rotate. Furthermore, the threaded engagement between the first bidirectional screw and the threaded tube drives the two threaded tubes to move relative to each other. This allows the adjusting block to be moved by the moving rod, thereby adjusting the tension of the sanding belt and preventing the sanding belt from shifting position.
[0042] 4. In this utility model, by setting the second correction mechanism, the rotation of the second handwheel can drive the second bidirectional screw to rotate. At the same time, the threaded engagement between the second bidirectional screw and the limiting plate can drive the two limiting plates to move relative to each other. Thus, the sanding belt can be limited by the limiting post, thereby further preventing the sanding belt from shifting position.
[0043] 5. In this utility model, the arrangement of the frame, conveyor roller, sanding belt, drive mechanism, pressure detection mechanism, first correction mechanism and second correction mechanism facilitates the adjustment of the sanding belt tension by moving the adjustment block.

[0050] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0051] like Figures 1-4 As shown in the figure, this embodiment proposes a wide-band sander with a correction mechanism for rail vehicle parts, including a frame 1, conveyor rollers 2, sanding belt, drive mechanism, pressure detection mechanism, first correction mechanism and second correction mechanism. Two conveyor rollers 2 are rotatably mounted through the frame 1, and sanding belts are driven on the two conveyor rollers 2. The drive mechanism is mounted on the frame 1 to drive the conveyor rollers 2 to rotate. The pressure detection mechanism is mounted on the frame 1 to adjust the tension of the sanding belt. The first correction mechanism is mounted on the conveyor rollers 2 to adjust the tension length of the sanding belt. The second correction mechanism is mounted on the conveyor rollers 2 to limit the position of the sanding belt.
[0052] Reference Figure 2 and Figure 3 The pressure detection mechanism includes a support plate 3 and a pressure sensor 6. The support plate 3 is fixedly installed inside the frame 1. A support frame 4 is provided on one side of the support plate 3. The support frame 4 is slidably connected to the side wall of the frame 1. A support roller 5 is rotatably installed inside the support frame 4. The support roller 5 contacts the sanding belt. The pressure sensor 6 is fixedly installed between the support plate 3 and the support frame 4. During the movement of the sanding belt, it can press against the support roller 5. Thus, the pressure sensor 6 can detect the pressure of the sanding belt on the support roller 5. When the sanding belt is taut, the reading of the pressure sensor 6 is larger, while when the sanding belt is slack, the reading of the pressure sensor 6 is smaller, which facilitates the detection of the tension of the sanding belt.
[0053] Reference Figure 3 The drive mechanism includes a first cavity, a first gear ring 7, a first gear 8, and a first motor 9. The first cavity is opened inside the frame 1. The first gear ring 7 is fixedly mounted on one of the conveying rollers 2. The first gear 8 is rotatably mounted in the first cavity and meshes with the first gear ring 7. The first motor 9 is fixedly mounted on the frame 1, and the output end of the first motor 9 is fixedly connected to the first gear 8. The operation of the first motor 9 can drive the first gear 8 to rotate. At the same time, the meshing of the first gear 8 and the first gear ring 7 drives one of the conveying rollers 2 to rotate, thereby facilitating the movement of the sanding belt by the friction between the conveying roller 2 and the sanding belt.
[0054] Reference Figure 3 and Figure 4The first correction mechanism includes an adjustment groove, an adjustment block 10, and a moving mechanism. Multiple adjustment grooves are provided on the side wall of the conveyor roller 2. The adjustment block 10 is slidably disposed within the adjustment groove. The moving mechanism is mounted on the conveyor roller 2 and is used to drive multiple adjustment blocks 10 to move synchronously. The moving mechanism includes a first bidirectional screw 11, a threaded tube 12, a moving rod 13, and a synchronous rotation mechanism. The first bidirectional screw 11 is rotatably disposed within the adjustment groove. Two threaded tubes 12 are threadedly fitted onto the first bidirectional screw 11. The moving rod 13 is hinged between the threaded tube 12 and the adjustment block 10. The synchronous rotation mechanism is mounted on the conveyor roller 2 and is used to drive multiple first bidirectional screws 11 to rotate synchronously. The synchronous rotation mechanism includes a second cavity, a second gear 15, and a first handwheel 16. The second cavity is located on the conveyor roller 2, and multiple third gears 14 are rotatably disposed within the second cavity. 14 is fixedly connected to the first bidirectional screw 11. The second gear 15 is rotatably mounted on the side wall of the second cavity. The second gear 15 meshes with the third gear 14. The first handwheel 16 is rotatably mounted on the conveying roller 2. A drive rod is fixedly mounted between the first handwheel 16 and the second gear 15. The side wall of the adjusting block 10 is arc-shaped and has anti-slip texture. The rotation of the first handwheel 16 can drive the second gear 15 to rotate. At the same time, the meshing of the second gear 15 and the third gear 14 drives the third gear 14 and the first bidirectional screw 11 to rotate. Then, the threaded engagement of the first bidirectional screw 11 and the threaded tube 12 drives the two threaded tubes 12 to move relative to each other. Thus, the adjusting block 10 can be moved by the moving rod 13. The tension of the sanding belt can be adjusted by the movement of the adjusting block 10, thereby preventing the sanding belt from shifting position.
[0055] Reference Figure 3 and Figure 4 The second correction mechanism includes a third cavity, limiting discs 17, and a relative movement mechanism. The third cavity is located inside the conveyor roller 2, and multiple limiting grooves are provided on the side wall of the third cavity. Two limiting discs 17 are slidably arranged inside the third cavity, and multiple limiting posts 18 are provided on the side wall of the limiting discs 17. The limiting posts 18 extend out of the conveyor roller 2 through the limiting grooves. The relative movement mechanism is arranged on the conveyor roller 2 and is used to drive the two limiting discs 17 to move relative to each other. The relative movement mechanism includes a second bidirectional screw 19 and a second handwheel 20. The second bidirectional screw 19 is rotatably mounted in the third cavity. Inside the cavity, the second bidirectional screw 19 passes through the limiting plate 17 via a threaded engagement. The second handwheel 20 is rotatably mounted on the conveying roller 2 and is fixedly connected to the second bidirectional screw 19. The limiting post 18 is rotatably connected to the limiting plate 17. The rotation of the second handwheel 20 can drive the second bidirectional screw 19 to rotate. At the same time, the threaded engagement between the second bidirectional screw 19 and the limiting plate 17 can drive the two limiting plates 17 to move relative to each other. Thus, the limiting post 18 can limit the sanding belt, thereby further preventing the sanding belt from shifting position.
[0056] In this embodiment, during use, the operation of the first motor 9 drives the first gear 8 to rotate. Simultaneously, the meshing of the first gear 8 with the first gear ring 7 drives one of the conveyor rollers 2 to rotate. This facilitates the movement of the sanding belt through the friction between the conveyor roller 2 and the sanding belt. During movement, the sanding belt presses against the support roller 5. The pressure sensor 6 detects the pressure force of the sanding belt on the support roller 5. The pressure sensor 6 reads a larger value when the sanding belt is taut and a smaller value when the sanding belt is slack, thus facilitating the detection of the sanding belt tension. When the pressure sensor 6 reads a smaller value, the operator turns off the first motor 9 and then rotates the first handwheel 16. The rotation of the first handwheel 16 drives the second gear 15 to rotate. The first gear 14 rotates through the meshing of the second gear 15 and the third gear 14, causing the third gear 14 and the first bidirectional screw 11 to rotate. The first bidirectional screw 11 then rotates through the threaded engagement of the threaded tube 12, causing the two threaded tubes 12 to move relative to each other. This allows the adjusting block 10 to move via the moving rod 13, thus adjusting the tension of the sanding belt and preventing it from shifting position. Simultaneously, the operator rotates the second handwheel 20, which rotates the second bidirectional screw 19. The second bidirectional screw 19 rotates through the threaded engagement of the limiting disc 17, causing the two limiting discs 17 to move relative to each other. This allows the limiting post 18 to limit the sanding belt, further preventing it from shifting position.
[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
