Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wood processing equipment, and in particular to a polishing and sanding device for wooden furniture. Background Technology
[0002] Polishing and sanding can significantly improve the smoothness and gloss of wooden furniture surfaces. By using sandpaper or polishing tools, imperfections and uneven areas on the wood surface can be removed, making the wood surface smoother and more refined. For example, in the production of wooden flooring, each plank needs to undergo fine sanding and polishing to ensure a smooth and glossy surface with a deep and elegant tone.
[0003] In existing technologies, polishing and sanding wooden furniture requires sequential operations and cannot be done in a coordinated manner. For example, existing robotic arms use a rotating drive to switch between polishing brushes and sanding heads to polish and sand the wooden boards sequentially. Therefore, we propose a wooden furniture polishing and sanding device to solve the above problems. Utility Model Content

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1-4As shown, a wood furniture polishing and sanding device is disclosed, comprising a frame 1, with two L-shaped legs fixedly connected to the bottom of the frame 1. Two drive rollers 2 are rotatably connected inside the frame 1 via existing bearings. Bearings are fixedly fitted at both ends of each drive roller 2, with the outer rings of the bearings fixedly connected to the inner wall of the frame 1. A bracket is fixedly connected to the outer wall of the frame 1, and a first motor 3 is fixedly connected to the top of the bracket. A circular hole is formed on the outer wall of the frame 1, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the first motor 3. One end of the output shaft of the first motor 3 is fixedly connected to the outer wall of one of the drive rollers 2. The same sanding belt 4 is fitted onto the outer walls of both drive rollers 2. The operation of the first motor 3 drives the connected drive roller 2 to rotate, thereby causing the sanding belt 4 to rotate counterclockwise.
[0023] A lower baffle 5 is fixedly connected inside the frame 1. A wooden board 6 is placed on top of the sanding belt 4. Two first cylinders 7 are fixedly connected to the outer wall of the frame 1. Two sliding holes are opened on the outer wall of the frame 1. The inner walls of the two sliding holes are slidably connected to the outer walls of the output ends of the two first cylinders 7 respectively. The operation of the first cylinders 7 drives the rectangular limiting plates 8 to move. Rectangular limiting plates 8 are fixedly connected to the outer walls of the output ends of the two first cylinders 7. The outer walls of the rectangular limiting plates 8 are in contact with the outer walls of the wooden board 6. The two rectangular limiting plates 8 move relative to each other and contact the wooden board 6 to assist the wooden board 6 in stable sanding.
[0024] The top of the frame 1 is fixedly connected to the equipment frame 9, and the outer wall of the equipment frame 9 is fixedly connected to the second cylinder 10. The equipment frame 9 supports the second cylinder 10. The bottom of the output end of the second cylinder 10 is fixedly connected to the L-shaped baffle 11. The outer wall of the L-shaped baffle 11 is slidably connected to the outer wall of the frame 1. The L-shaped baffle 11 prevents the wooden board 6 from moving further.
[0025] Two guide rods 12 are fixedly connected inside the frame 1. The outer walls of the two guide rods 12 are slidably fitted with the same rectangular frame 14. The two guide rods 12 assist the rectangular frame 14 to move left and right. A third cylinder 13 is fixedly connected inside the equipment frame 9. The outer wall of the output end of the third cylinder 13 is fixedly connected to the outer wall of the rectangular frame 14. The operation of the third cylinder 13 drives the rectangular frame 14 to move left and right, which facilitates the subsequent polishing brush roller 17 to polish the top of the wooden board 6.
[0026] The bottom of the rectangular frame 14 is provided with a polishing mechanism, which includes a polishing brush roller 17. A fourth cylinder 15 is fixedly connected inside the rectangular frame 14. A through hole is opened at the bottom of the rectangular frame 14. The inner wall of the through hole is slidably connected to the outer wall of the output end of the fourth cylinder 15. A U-shaped frame 16 is fixedly connected to the top of the output end of the fourth cylinder 15. The U-shaped frame 16 assists the polishing brush roller 17 to rotate.
[0027] Both ends of the polishing brush roller 17 are rotatably connected to the inner wall of the U-shaped frame 16. Both ends of the polishing brush roller 17 are fixedly fitted with existing bearings. The outer ring of the bearing is fixedly connected to the inner wall of the U-shaped frame 16. An installation plate is fixedly connected to the outer wall of the U-shaped frame 16. A second motor 18 is fixedly connected to the top of the installation plate. One end of the output shaft of the second motor 18 passes through the outer wall of the U-shaped frame 16 and is fixedly connected to the outer wall of the polishing brush roller 17. The operation of the second motor 18 drives the polishing brush roller 17 to rotate clockwise.
[0028] The rectangular frame 14 is equipped with a dust removal mechanism, which includes a metal corrugated pipe 20. An L-shaped frame 19 is fixedly connected to the outer wall of the rectangular frame 14. The outer wall of the L-shaped frame 19 has an installation hole. The inner wall of the installation hole is fixedly connected to the outer wall of the metal corrugated pipe 20. One end of the metal corrugated pipe 20 passes through the inner wall of the equipment frame 9 and is fixedly connected to a dust removal fan.
[0029] Working principle: In use, the wooden board 6 to be polished is placed on the sanding belt 4. The first motor 3 rotates, driving the connected transmission roller 2 to rotate, causing the sanding belt 4 to move the board 6 to the left. After moving a certain distance to the left, the board 6 is stopped by the L-shaped baffle 11. At this point, the board 6 stops moving. The two first cylinders 7 operate synchronously, driving the two rectangular limit plates 8 to move relative to each other. The two rectangular limit plates 8 contact the board 6, assisting in horizontal sanding and preventing the board 6 from shaking during sanding. Meanwhile, the sanding belt 4 at the bottom continues to rotate, performing preliminary sanding on the bottom of the board 6. Simultaneously, the third cylinder 13 drives the rectangular frame 14 to move left and right, and the fourth cylinder 15 drives the U-shaped frame 16 to move downwards. The frame 16 moves downward, driving the second motor 18 and polishing brush roller 17 to move downward as well. The second motor 18 rotates, causing the polishing brush roller 17 to rotate. As the polishing brush roller 17 moves downward and rotates, it presses down on the wooden board 6, further grinding the bottom of the wooden board 6 against the sanding belt 4 and performing preliminary polishing on the top of the wooden board 6. During polishing, the dust removal fan operates, creating negative pressure inside the metal corrugated pipe 20 to suck away the dust generated during the polishing process. The second cylinder 10 operates, driving the L-shaped baffle 11 to move upward, and the first cylinder 7 operates, driving the rectangular limit plate 8 to reset. The wooden board 6 is discharged from the left side of the frame 1 by the rotation of the sanding belt 4. The above process is repeated as the wooden board 6 is flipped over, achieving overall polishing of the wooden board 6.
