Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding and polishing equipment technology, and in particular to the belt wheel adjustment structure of a belt sander. Background Technology
[0002] A belt sander is a mechanical processing device that uses a sanding belt as a grinding medium. It uses the abrasive on the surface of the sanding belt to grind, polish, or deburr workpieces. Belt sanders can adapt to workpieces of various materials and complex shapes and are an indispensable tool in industrial production and daily life.
[0003] However, during long-term operation, the angle of the belt sander may shift due to mechanical vibration, excessive load, or external impact, causing the belt sander and driven wheel to become non-parallel. This can lead to belt misalignment, uneven belt wear, or even damage to the equipment, severely impacting production efficiency. Therefore, further improvements to the existing technology are necessary. Utility Model Content

[0030] Example: Figure 1-8 As shown, the belt sander's belt wheel adjustment structure includes a frame 1, an adjustment plate 2, a belt sander 3, and a lifting device 4. The belt sander 3 is mounted on the top surface of the adjustment plate 2. The movable end of the lifting device 4 is mounted on one end of the bottom surface of the adjustment plate 2 through the first through hole 11 of the frame 1. When the movable end of the lifting device 4 is pushed upward, the adjustment plate 2 tilts away from the end of the lifting device 4. This application can adjust the angle of the belt sander by cooperating with the lifting device and the adjustment plate. By correcting the angle of the belt sander, the belt sander is made parallel to the driven wheel, thereby reducing the phenomenon of belt deviation or detachment, ensuring that the belt sander always runs stably, making the belt sander more evenly stressed, and thus extending the service life of the belt sander.
[0031] The device includes a fixed base 5. The bottom surface of the adjusting plate 2 away from the lifting device 4 is mounted on the frame 1 through the fixed base 5. When the lifting device extends upward or retracts downward, the end of the adjusting plate away from the lifting device is fixed to the frame through the fixed base.
[0032] The device includes a push cylinder 6. The movable end of the push cylinder 6 is mounted on the bottom surface of the adjusting plate 2 through the second through hole 12 of the frame 1 and is located at the end away from the connection between the lifting device 4 and the fixed seat 5. When the adjusting plate 2 is tilted away from the lifting device 4, the movable end of the push cylinder 6 pushes upward to abut against the bottom surface of the adjusting plate 2. The push cylinder extends upward or retracts downward through the movable end to tilt the adjusting plate, thereby adjusting the angle of the sanding belt wheel.
[0033] The device includes a connecting seat 7, which is disposed on the movable end of the lifting device 4. It also includes a connecting rod 8. The fixed seat 5 and the connecting seat 7 are provided with openings 50 corresponding to the connecting rod 8. The adjusting plate 2 is provided with hinge holes 20 corresponding to the openings 50. The connecting rod 8 is assembled in the hinge holes 20 and the openings 50, so that when the pushing cylinder extends upward or retracts downward, the adjusting plate can tilt through the cooperation of the connecting rod, the hinge holes, and the openings. The openings make way for the connecting rods, reducing the mutual interference between the connecting rods and the connecting seat and the fixed seat.
[0034] The system includes a first fixed shaft 51, a first mounting hole 501 on the fixed base 5, and a sliding hole 801 on the connecting rod 8 corresponding to the first mounting hole 501. The first fixed shaft 51 is assembled in the first mounting hole 501 and the sliding hole 801, and the first fixed shaft 51 can slide in the first mounting hole 501 and the sliding hole 801.
[0035] and / or
[0036] Includes a second fixed shaft 71, the connecting seat 7 is provided with a second mounting hole 701, the connecting rod 8 is provided with a fixing hole 802 corresponding to the second mounting hole 701, the second fixed shaft 71 is assembled in the second mounting hole 701 and the fixing hole 802, the second fixed shaft 71 can slide in the first mounting hole 701 and the fixing hole 802, so that when the movable end of the lifting device pushes one end of the adjusting plate to move upward to realize the tilting of the adjusting plate, there is space in the sliding hole for the second fixed shaft to slide, reducing the possibility of the horizontal shaft interfering with the support when the support plate tilts.
[0037] The lifting device 4 includes a worm gear, a worm, and a lead screw. The worm is rotatably connected to the worm gear, and the worm gear has a threaded hole. The lead screw has a thread corresponding to the threaded hole. The lead screw is mounted in the worm gear and can move up and down through the engagement of the thread and the threaded hole. The lifting device can be raised and lowered by the worm gear, worm, and lead screw, which in turn allows the adjusting plate to tilt so that the angle of the sanding belt wheel can be adjusted.
[0038] The system includes a baffle 9, one end of which is connected to the frame 1 and the other end of which is positioned opposite the sanding belt wheel 3. The baffle acts as a barrier to prevent the rotating wheel from becoming loose, falling off, or being thrown out due to prolonged high-speed rotation, which could lead to an accident.
[0039] The device also includes a bushing 13, which is installed in the first through hole 11 and / or the second through hole 12. The bushing is installed in the first through hole to reduce the friction between the moving end of the lifting device and the inside of the first through hole. The bushing is installed in the second through hole to reduce the friction between the moving end of the lifting device and the inside of the second through hole, thereby reducing friction that could lead to wear or damage to the components.
[0040] The system includes a motor 21, which is mounted on the adjustment plate 2. The sanding belt wheel 3 is mounted on the output end of the motor 21, and the motor is configured to drive the sanding belt wheel.
