Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a wood processing edge and corner sanding device. Background Technology

[0002] When wood panels have burrs on the edges or corners, or when the edges or corners need to be trimmed and sanded, a sanding device is required to process the wood panels.

[0003] Chinese patent CN212705906U discloses a continuous sanding device for the edges and corners of wooden furniture. The patent describes a device that "includes an operating table, with a housing fixedly connected to the rear surface of the operating table. A first motor is fixedly connected to the inner wall on the right side of the housing. The output end of the first motor on the left side is connected to one end of a first screw. The other end of the first screw is fixed to the inner wall on the left side of the housing via a first bearing. A first slider is threadedly connected to the first screw. The upper surface of the first slider is rotatably connected to one end of a second screw via a second bearing. The other end of the second screw passes through a support housing and is connected to the output end of a second motor." This sanding device uses a sanding head to sand the wood. However, because the size of the sanding head is relatively fixed, changing the model of the sanding head is necessary when sanding a large number of wood pieces, increasing the overall complexity of using the sanding device. Furthermore, traditional sanding heads cannot adjust their longitudinal length according to the thickness of the wood, thus reducing the overall effectiveness of the sanding device.

[0023] 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.

[0024] Please see Figure 1 , Figure 3 as well as Figure 4This embodiment proposes a wood panel edge sanding device, including a workbench 1. A fixing assembly 2 for placing wood panels is provided at the top of the workbench 1. A sanding table 3 for sanding is fixedly installed on one side of the workbench 1. A first sanding wheel 31 is rotatably connected to the inner wall of the top of the sanding table 3. Two second sanding wheels 32 for extending the sanding height are provided at the bottom of the first sanding wheel 31. A third sanding wheel 33 for extending the sanding height is provided at the bottom of the second sanding wheels 32. Three connecting posts 34 for connecting are slidably connected to the inner walls of the second sanding wheels 32 and the third sanding wheels 33. The inner walls of the bottom ends of the grinding wheel 31 and the second grinding wheel 32 are provided with three connecting holes 35 for connection. The inner walls of the second grinding wheel 32 and the third grinding wheel 33 are provided with connecting components 4 for inserting the driving connecting pin 34 into the connecting holes 35. The inner wall of the first grinding wheel 31 is slidably connected to a driving limiting pin 5 for positioning. The inner wall of the driving limiting pin 5 is provided with a first lifting component 6 for driving the limiting pin 5 to rise and fall. Three racks 51 are fixedly installed on the outer side of the driving limiting pin 5. The inner walls of the second grinding wheel 32 and the third grinding wheel 33 are slidably connected to fixed limiting pins 7 for positioning. The outer side of the fixed limiting post 7 is slidably connected to the inner wall of the bottom end of the grinding table 3. The inner wall of the fixed limiting post 7 is provided with a second lifting component 8 for fixing the lifting of the fixed limiting post 7. The inner wall of the top end of the grinding table 3 is provided with a driving component 9 for driving the first grinding wheel 31 to rotate. The wooden board can be placed on the fixed component 2 for height adjustment and rotation to facilitate grinding. The number of rotations of the first grinding wheel 31, the second grinding wheel 32, and the third grinding wheel 33 can be adjusted according to the thickness of the wooden board. The first lifting component 6 drives the first lead screw 61, so that the driving limiting post 5 can be moved to the first grinding wheel 31. The grinding wheel 31, the second grinding wheel 32, and the third grinding wheel 33 slide up and down internally. This allows the connecting column 34 to be driven upward and connected to the previous grinding wheel by the action of the rack 51 on the driving limit column 5 on the connecting component 4. The grinding wheels can then be connected according to the length of the wooden board, extending the longitudinal length that can be ground. At the same time, the fixed limit column 7 can be adjusted by driving the second lifting component 8, so that the fixed limit column 7 follows the height of the driving limit column 5. This allows the grinding wheel that does not need to rotate to be limited and fixed between it and the fixed limit column 7, reducing the energy consumption caused by the overall rotation of the grinding wheel.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5This embodiment proposes a wood panel edge sanding device. The first lifting assembly 6 includes a first lead screw 61 threadedly connected to the inner wall of a drive limiting post 5. The two ends of the first lead screw 61 are rotatably connected to the inner walls of the two ends of the sanding table 3. Multiple limiting rods 62 are slidably connected to the inner wall of the drive limiting post 5. The top ends of the multiple limiting rods 62 are fixedly connected to the top inner wall of the sanding table 3. By operating the first lead screw 61, the first sanding wheel 31 does not rotate, and the drive limiting post 5 slides downward inside the first sanding wheel 31, the second sanding wheel 32, and the third sanding wheel 33. While being driven by the first lead screw 61, the drive limiting post 5 is held in place by the limiting rods 62. The internal vertical sliding mechanism includes a second lead screw 81 threadedly connected to the inner wall of a fixed limiting post 7. The bottom end of the second lead screw 81 is rotatably connected to the inner wall of the bottom end of the grinding table 3. An adjusting gear ring 82 is fixedly installed on the outer side of the bottom end of the second lead screw 81. An operating rod 83 is rotatably connected to the inner wall of the bottom end of the grinding table 3. An adjusting gear 84 is fixedly installed on the outer side of the bottom end of the operating rod 83. The adjusting gear 84 meshes with the adjusting gear ring 82. The second lead screw 81 can be rotated inside the fixed limiting post 7 by rotating the operating rod 83 and the adjusting gear 84 acting on the adjusting gear ring 82. This causes the fixed drive post to slide inside the first grinding wheel 31, the second grinding wheel 32, and the third grinding wheel 33, thus fixing the grinding wheels that do not need to rotate. The connecting assembly 4 includes three drive rods 41 rotatably connected to the inner walls of the second grinding wheel 32 and the third grinding wheel 33. Main gears 42 are fixedly installed at both ends of the three drive rods 41, meshing with racks 51. Three transition rods 43 and connecting screws 44 are also rotatably connected to the inner walls of the second grinding wheel 32 and the third grinding wheel 33. The outer ends of the tops of the three connecting screws 44 are threaded to the inner wall of the connecting column 34. The connecting assembly 4 also includes connecting gears 45 fixedly installed at the bottom ends of the transition rods 43 and the connecting screws 44, meshing with transition gears 46. Bevel gears 47 are fixedly installed on the outer sides of the drive rods 41 and the tops of the transition rods 43. While the driving limit column 5 is sliding up and down, it can be adjusted via the racks 51 on its upper part. Driven by the main gear 42, multiple drive rods 41 rotate synchronously inside the grinding wheel. The bevel gear 47 then drives the transition rod 43 to rotate. Furthermore, the transition gear 46 and connecting gear 45 interact to drive the connecting screw 44 to rotate. This drives the connecting pin 34 to slide upwards from inside the grinding wheel and insert into the connecting hole 35 of the previous grinding wheel, thus connecting the grinding wheels. Based on the height of the wood board, the first grinding wheel 31 can be connected to the second grinding wheel 32, the second grinding wheel 32 can be connected to another grinding wheel, and the second grinding wheel 32 can be connected to the third grinding wheel 33. This increases the thickness of the wood board that the overall grinding table 3 can grind in one pass. The drive assembly 9 includes a drive gear ring 91 fixedly mounted on the outer side of the top of the first grinding wheel 31.A drive gear 92 is fixedly installed on the inner wall of the top of the grinding table 3. A drive motor 93 is fixedly installed on the top of the grinding table 3. The output end of the drive motor 93 is fixedly connected to the drive gear 92. When the first grinding wheel 31 needs to rotate, the drive motor 93 can drive the drive gear 92 to rotate. Then, the drive gear 92 can drive the first grinding wheel 31 to rotate through the action of the drive gear ring 91. The fixed limiting post 7 and the first lead screw 61 inside rotate synchronously. When the first grinding wheel 31, the second grinding wheel 32 and the third grinding wheel 33 are connected, they can be driven to rotate synchronously. The fixed assembly 2 includes a movable plate 21 that is slidably connected to the inner wall of the worktable 1. A base plate 22 is rotatably connected to the inner wall of the movable plate 21. An electric hydraulic rod 23 is fixedly installed on the top of the base plate 22. The telescopic end of the electric hydraulic rod 23 is fixedly installed. The assembly includes a top plate 24 and a fixed component 2, which also includes two electrically operated telescopic rods 25 fixedly installed at both ends of a movable plate 21. The fixed ends of the two electric telescopic rods 25 are fixedly connected to the inner sidewall of the worktable 1. A forward and reverse motor 26 is fixedly installed at the bottom end of the movable plate 21, and the output end of the forward and reverse motor 26 is fixedly connected to the bottom end of the top plate 24. The wooden board can be placed on the top plate 24, and the top plate 24 is raised and lowered according to the thickness of the wooden board via an electric hydraulic rod 23, so that the wooden board at the top position is level with the first grinding wheel 31. At the same time, the wooden board can be moved closer to the grinding table 3 by the extension and retraction of the electric telescopic rods 25. When the wooden board needs to be rotated, the forward and reverse motor 26 can drive the bottom plate 22, the electric hydraulic rod 23, and the top plate 24 to rotate, so that the wooden board can be rotated to grind the edges and corners.

[0026] In this embodiment, during use, the wooden boards are first placed on the top plate 24, and the height of the top plate 24 is adjusted according to the thickness of the stacked wooden boards. At this time, the first lead screw 61 can be rotated according to the height of the wooden boards, so that the drive limiting post 5 can slide up and down inside the first grinding wheel 31, the second grinding wheel 32, and the third grinding wheel 33. Thus, the connecting post 34 is driven upward to connect with the previous grinding wheel by the action of the rack 51 on the drive limiting post 5 on the main gear 42. Then, the entire grinding wheel can be adjusted according to the thickness of the wooden boards. The length is extended and adjusted, and the fixed limit post 7 is driven to rise and fall by the second lead screw 81, so that the grinding wheel that does not need to rotate can be kept in a stationary state, reducing the energy consumption of the overall grinding device and thus improving the overall grinding effect. After the number of grinding wheels 31, 32 and 33 is adjusted, the grinding wheels connected in sequence can be rotated by the first grinding wheel 31, so that multiple wood boards can be ground at the same time without changing the grinding wheel model.

[0027] 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.
