Description

Technical Field

[0001] This invention relates to the field of sanding equipment technology, specifically a sanding equipment for processing shaft-type wood. Background Technology

[0002] With the development of wood processing technology and changes in market demand, consumers have increasingly higher requirements for the surface quality of wood products. For example, they require wood surfaces to be smoother and free of defects, and they have higher requirements for the precision and fineness of wood surface treatment. Therefore, a more efficient and precise sanding equipment is needed to meet these needs.

[0003] Patent CN221390538U relates to a grinding device for machining shaft parts, belonging to the field of grinding technology. The device includes a grinding apparatus, which comprises a worktable. A support column is fixedly connected to the bottom of the worktable, and a positioning plate is fixedly connected to the top of the worktable. A motor is fixedly connected to one side of the positioning plate. The device utilizes the thrust of an electric telescopic rod in conjunction with components such as a fixed plate, a force-bearing rod, and a hydraulic cylinder. This allows the electric telescopic rod to push the force-bearing rod, which in turn pushes a hydraulic rod through a piston inside the hydraulic cylinder, thus driving the hydraulic rod to move... The function of the clamping block A is to clamp the shaft. The force of the rotating rod driven by the output shaft of the motor, together with the worktable, positioning plate and grinding shaft, realizes the function of the rotating rod driven by the output shaft of the motor, and the grinding shaft driven by the rotation of the rotating rod, thus achieving the grinding effect. However, in the process of fixing wood, if the wood diameter is large, it is difficult to clamp effectively during the grinding process, and the wood is prone to falling out of the grinding area. Therefore, a grinding device for shaft wood processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a sanding device for processing shaft-type wood, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a sanding device for processing shaft-type wood, including a base platform, a support plate fixedly connected to the top of the base platform, a roller plate fixedly connected to the right side of the support plate, a three-jaw clamping platform provided at the rear of the base platform, a threaded rod rotatably connected to the inner wall of the base platform, a straight bar fixedly connected to the inner wall of the base platform, a movable platform threadedly connected to the circumferential surface of the threaded rod, a support platform fixedly connected to the top of the movable platform, and a cylinder fixedly connected to the left side of the support platform. A movable rod is fixedly connected to the output end of the cylinder. A grinding plate is provided on the right side of the movable rod. A fixed rod is rotatably connected to the inner wall of the base. A rotating plate is fixedly connected to the circumferential surface of the fixed rod. An arc-shaped plate is fixedly connected to the circumferential surface of the fixed rod. A hollow strip is slidably connected to the surface of the straight bar. A support plate is fixedly connected to the top of the hollow strip. A reset rod is slidably connected to the inner wall of the straight bar via a spring. A chip removal mechanism for dust removal is provided on the top of the movable table. A grinding plate is provided on the top of the base. The quick-release mechanism facilitates easy disassembly and ensures uniform sanding of the wood surface during processing, preventing excessive or insufficient sanding in certain areas. During sanding, the distance between the sanding plate and the wood can be adjusted according to the wood's diameter, allowing for flexible handling of woods of different diameters. It also prevents the sanding plate from becoming too close, thus avoiding excessive wear. A motor is installed at the front of the threaded rod, driving its rotation. The surface of the moving platform is slidably connected to the inner wall of the base, and the circumferential surface of the moving rod is slidably connected to the inner wall of the support platform. The top of the rotating plate contacts the bottom of the perforated strip, and the top of the reset rod is fixedly connected to the bottom of the support plate. The sanding plate is used to sand the wood surface. When the wood is placed on top of the support plate, it ensures that the sanding is not uneven or inaccurate due to shaking or falling off, preventing displacement or falling during rotation, and also preventing the clamping point from being out of center.

[0006] Preferably, the chip removal mechanism includes a chip collection box, which is installed on the top of the moving platform. A connecting pipe is fixedly connected to the inner wall of the chip collection box, and a vacuum cleaner is fixedly connected to the top of the connecting pipe. A second support plate is fixedly connected to the right side of the base platform. A sliding rod is slidably connected to the inner wall of the second support plate via a spring. A straight plate is fixedly connected to the circumferential surface of the sliding rod. A rotating wheel is rotatably connected to the inner wall of the straight plate, and an arc-shaped plate is fixedly connected to the circumferential surface of the straight plate. During the sanding process, the chips and dust generated during sanding are sucked into the chip collection box through the connecting pipe, thus preventing the chips and dust from affecting the operator's breathing, improving the working environment, and reducing the risk of occupational diseases. When sanding is finished, the support platform pushes the arc-shaped plate to move. The rotating wheel is used to improve the stability of the wood during sanding. When sanding is completed, it can exert downward pressure on the wood, further improving its stability and preventing eccentric force at the front end of the wood from causing it to detach.

[0007] Preferably, the quick-release mechanism includes a second fixing rod fixedly connected to the inner wall of the chip collection box. A pressure plate is slidably connected to the circumferential surface of the second fixing rod. An elastic rod is fixedly connected to the top of the pressure plate by a spring. A long plate is fixedly connected to the top of the elastic rod. A protrusion is fixedly connected to the top of the long plate. A U-shaped frame is fixedly connected to the top of the base platform. A protrusion is fixedly connected to the bottom of the U-shaped frame. An L-shaped plate is fixedly connected to the top of the sanding plate. A fixing block is fixedly connected to the circumferential surface of the moving rod. A lead screw is threadedly connected to the inner wall of the L-shaped plate. During the sanding process... The downward movement of the pressure plate compacts the wood chips stored inside the chip collection box, facilitating their later recycling and utilization. It also reduces the volume of wood chips, minimizing the need for frequent cleaning of the collection box. The inner wall of the collection box is slidably connected to the circumferential surface of the elastic rod, and the inner wall of the fixing block is threadedly connected to the circumferential surface of the lead screw. When the grinding plate needs replacement due to prolonged use, it can be done quickly, reducing downtime and making the production process more continuous. Furthermore, different types of grinding discs can be quickly switched according to actual needs, increasing the equipment's adaptability and flexibility to meet various processing requirements.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This sanding device for shaft-type wood processing, through the coordinated operation of a base, a support plate, a roller plate, a three-jaw clamping table, a threaded rod, a straight bar, a moving table, a support table, a cylinder, a moving rod, a sanding plate, a fixed rod, a rotating plate, an arc-shaped plate, a hollow strip, a support plate, and a reset rod, ensures uniform sanding of the wood surface when processing begins, avoiding excessive or insufficient sanding in certain areas. During sanding, the distance between the sanding plate and the wood can be adjusted according to the wood's diameter, allowing for flexible handling of wood of different diameters. It also prevents the distance between the wood and the sanding plate from being too close, thus avoiding excessive wear of the sanding plate. When the wood is placed on top of the support plate, it ensures that the wood will not shake or fall during sanding, preventing uneven or inaccurate sanding. It also prevents the wood from shifting or falling during rotation and avoids the problem of the clamping point being out of center.

[0009] 2. This sanding device for processing shaft-type wood, through the coordinated operation of the chip collection box, connecting pipe, and vacuum cleaner, draws the wood chips into the inside of the chip collection box through the connecting pipe during the sanding process. This prevents the wood chips and powder generated during the sanding process from affecting the operator's breathing, thereby improving the working environment of workers and reducing the risk of occupational diseases.

[0010] 3. This sanding device for shaft-type wood processing, through the coordinated operation of the second support plate, the sliding rod, the straight plate, the rotating wheel, and the second arc plate, can generate downward pressure on the wood during the sanding process when the sanding work is completed, thereby further improving the stability of the wood during the sanding process and preventing the front end of the wood from generating eccentric force, which would cause the wood to detach.

[0011] 4. This type of sanding device for processing wood shafts, through the coordinated operation of fixed rod two, pressure plate, elastic rod and long plate, when sanding wood, the pressure plate moves down to compact the wood chips stored in the chip collection box, which facilitates the recycling and utilization of wood chips later, and at the same time reduces the volume of wood chips and reduces the need for workers to clean the chip collection box frequently.

[0012] 5. This sanding device for shaft-type wood processing, through the coordinated operation of protrusion one, U-shaped frame, protrusion two, L-shaped plate, fixed block and screw, can quickly replace the sanding plate when it needs to be replaced due to long service time, thereby reducing downtime and making the production process more continuous. At the same time, different types of sanding discs can be quickly switched according to actual needs, increasing the adaptability and flexibility of the equipment and meeting different processing requirements.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-7One embodiment of the present invention is as follows: a sanding device for processing shaft-type wood includes a base 1, a support plate 2 fixedly connected to the top of the base 1, a roller plate 3 fixedly connected to the right side of the support plate 2, a three-jaw clamp 4 provided at the rear of the base 1, a threaded rod 5 rotatably connected to the inner wall of the base 1, a straight bar 6 fixedly connected to the inner wall of the base 1, a movable table 7 threadedly connected to the circumferential surface of the threaded rod 5, a support platform 8 fixedly connected to the top of the movable table 7, a cylinder 9 fixedly connected to the left side of the support platform 8, and a moving rod 10 fixedly connected to the output end of the cylinder 9. A grinding plate 11 is provided on the right side of the moving rod 10. A fixed rod 12 is rotatably connected to the inner wall of the base 1. A rotating plate 13 is fixedly connected to the circumferential surface of the fixed rod 12. An arc plate 14 is fixedly connected to the circumferential surface of the fixed rod 12. A hollow strip 15 is slidably connected to the surface of the straight bar 6. A support plate 16 is fixedly connected to the top of the hollow strip 15. A reset rod 17 is slidably connected to the inner wall of the straight bar 6 through a spring. A dust removal mechanism 18 for dust treatment is provided on the top of the moving platform 7. A quick-release mechanism 19 for easy disassembly is provided on the top of the base 1. When processing the wood begins, the wood is placed on top of the pallet 16 and fixed to the three-jaw chuck 4. After the wood is fixed, the motor starts and drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 passes through the threaded groove on the surface, allowing the moving table 7 to move back and forth in the direction of the motor's rotation. The movement of the moving table 7 will drive the support table 8 to move synchronously. The movement of the support table 8 will drive the cylinder 9 to move. The movement of the cylinder 9 will drive the moving rod 10 to move. The movement of the moving rod 10 will drive the sanding plate 11 to move, thereby ensuring that the wood surface is sanded evenly and avoiding problems such as excessive or insufficient sanding in certain areas. When sanding the wood, the cylinder 9 will start and drive the moving rod 10 to move. The movement of the moving rod 10 will drive the sanding plate 11 to move, thereby adjusting the distance between the sanding plate 11 and the wood according to the diameter of the wood. This allows for the free handling of wood of different diameters and avoids the situation where the distance between the wood and the sanding plate 11 is too close, resulting in excessive wear of the sanding plate 11. A motor is installed at the front of the threaded rod 5, and the threaded rod 5 will be driven by the motor to rotate. The surface of the moving table 7 is slidably connected to the inner wall of the base 1. The circumferential surface of the moving rod 10 is slidably connected to the inner wall of the support table 8. The top of the rotating plate 13 is in contact with the bottom of the hollow strip 15. The top of the reset rod 17 is fixedly connected to the bottom of the support plate 16. The sanding plate 11 will be used to sand the surface of the wood. When the wood is placed on top of the support plate 16, the support plate 16 is forced to move downwards due to its own weight. The downward movement of the support plate 16 causes the reset rod 17 to move downwards and compress the spring. The downward movement of the support plate 16 causes the hollow strip 15 to move downwards. The downward movement of the hollow strip 15 exerts a squeezing force on the rotating plate 13, causing the rotating plate 13 to rotate counterclockwise. The rotation of the rotating plate 13 causes the fixing rod 12 to rotate, which in turn causes the arc plate 14 to rotate counterclockwise. This pushes the wood placed on the surface of the roller plate 3 towards the center, while ensuring that the wood will not be unevenly or inaccurately sanded due to shaking or falling off during sanding. It also prevents the wood from shifting or falling off during rotation. During the rotation, the wood will contact the rollers on the inner wall of the arc plate 14, ensuring that the wood can rotate normally. After fixing, the wood is then docked and fixed to the three-jaw clamping table 4 to prevent the clamping point from being out of center.

[0017] Working principle: When processing wood begins, the wood is placed on top of the pallet 16 and fixed to the three-jaw clamp 4. The movement of the support table 8 drives the cylinder 9 to move, which in turn drives the moving rod 10 to move, which in turn drives the sanding plate 11 to move, thus ensuring that the wood surface is sanded evenly. When sanding the wood, the cylinder 9 is activated and drives the moving rod 10 to move, which in turn drives the sanding plate 11 to move, thereby adjusting the distance between the sanding plate 11 and the wood according to the diameter of the wood. When the wood is placed on top of the pallet 16, the rotation of the fixing rod 12 drives the arc plate 14 to rotate counterclockwise, thus pushing the wood placed on the roller plate 3 towards the center, preventing it from shifting or falling during rotation. After fixing, the wood is then docked and fixed to the three-jaw clamp 4 to prevent the clamping point from being out of center.

[0018] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the chip removal mechanism 18 includes a chip collection box 181, which is installed on the top of the moving platform 7. The inner wall of the chip collection box 181 is fixedly connected to a connecting pipe 182. A vacuum cleaner 183 is fixedly connected to the top of the connecting pipe 182. A second support plate 184 is fixedly connected to the right side of the base platform 1. A sliding rod 185 is slidably connected to the inner wall of the second support plate 184 by a spring. A straight plate 186 is fixedly connected to the circumferential surface of the sliding rod 185. A rotating wheel 187 is rotatably connected to the inner wall of the straight plate 186. An arc-shaped plate 188 is fixedly connected to the circumferential surface of the straight plate 186. During the sanding process, the moving table 7 moves the chip collection box 181, which in turn moves the connecting pipe 182, which in turn moves the vacuum cleaner 183. Simultaneously, the vacuum cleaner 183 starts up, allowing it to move along with the sanding plate 11. This enables the vacuum cleaner 183 to suck the wood chips generated during sanding into the chip collection box 181 through the connecting pipe 182, thus preventing the wood chips and powder generated during sanding from affecting the operator's breathing, improving the working environment for workers, and reducing the risk of occupational diseases. When the sanding is finished, the support platform 8 will push the curved plate 188 to move, and the rotating wheel 187 will be used to improve the stability of the wood during the sanding process. When the sanding work is completed, the moving table 7 will drive the support table 8 to move forward. During the forward movement of the support table 8, it will come into contact with the curved plate 188 and squeeze the curved plate 188, causing it to move upward. The upward movement of the curved plate 188 will drive the straight plate 186 to move upward. The upward movement of the straight plate 186 will drive the sliding rod 185 to move upward and compress its own spring. The upward movement of the straight plate 186 will drive the rotating wheel 187 to move upward, allowing the rotating wheel 187 to leave the circumference of the wood. At this time, the wood can be removed. Similarly, when placing the wood, the sliding rod 185 will move downward through the spring and drive the straight plate 186 to move downward. The downward movement of the straight plate 186 will drive the rotating wheel 187 to move downward. This can generate downward pressure on the wood during the sanding process, thereby further improving the stability of the wood during the sanding process and preventing the front end of the wood from generating eccentric force, which could cause the wood to detach.

[0019] Working principle: During the sanding process, the vacuum cleaner 183 will start simultaneously, allowing it to move along with the sanding plate 11. This enables the vacuum cleaner 183 to suck the wood chips and dust generated during sanding into the dust collection box 181 through the connecting pipe 182, thus preventing the wood chips and dust generated during sanding from affecting the operator's breathing, improving the working environment and reducing the risk of occupational diseases. When the sanding work is completed, the moving table 7 will drive the support table 8 forward, allowing the rotating wheel 187 to leave the circumference of the wood, at which point the wood can be removed. Similarly, when placing the wood, the sliding rod 185 will move downward through the spring, driving the straight plate 186 downward, which can generate downward pressure on the wood during the sanding process, thereby further improving the stability of the wood during sanding.

[0020] The quick-release mechanism 19 includes a second fixed rod 191, which is fixedly connected to the inner wall of the chip collection box 181. A pressure plate 192 is slidably connected to the circumferential surface of the second fixed rod 191. An elastic rod 193 is fixedly connected to the top of the pressure plate 192 by a spring. A long plate 194 is fixedly connected to the top of the elastic rod 193. A protrusion 195 is fixedly connected to the top of the long plate 194. A U-shaped frame 196 is fixedly connected to the top of the base 1. A protrusion 197 is fixedly connected to the bottom of the U-shaped frame 196. An L-shaped plate 198 is fixedly connected to the top of the grinding plate 11. A fixed block 199 is fixedly connected to the circumferential surface of the moving rod 10. A screw rod 1910 is threadedly connected to the inner wall of the L-shaped plate 198. During the sanding process, the movement of the chip collection box 181 causes the fixed rod 191 to move, which in turn causes the pressure plate 192 to move. The pressure plate 192 then causes the elastic rod 193 to move, which in turn causes the long plate 194 to move. The long plate 194 then causes the protrusion 195 to move. During this movement, the protrusion 195 comes into contact with the protrusion 197 and is subjected to the squeezing force of the protrusion 197, forcing the protrusion 195 to move downward. The downward movement of the protrusion 195 causes the long plate 194 to move downward, which in turn causes the elastic rod 193 to move downward and compress its own spring. The downward movement of the elastic rod 193 then causes the pressure plate 192 to move downward. The downward movement of the pressure plate 192 compacts the wood chips stored inside the chip collection box 181, which facilitates the later recycling and utilization of the wood chips. At the same time, it reduces the volume of the wood chips and reduces the need for workers to clean the chip collection box 181 frequently. The inner wall of the chip collection box 181 is slidably connected to the circumferential surface of the elastic rod 193, and the inner wall of the fixing block 199 is threadedly connected to the circumferential surface of the lead screw 1910. When the grinding plate 11 needs to be replaced due to prolonged use, the screw 1910 is rotated by turning the knob. The rotation of the screw 1910 will move upward through the threaded groove inside the fixing block 199 and then disengage from the fixing block 199. This allows for the quick replacement of the grinding plate 11, reducing downtime and making the production process more continuous. At the same time, different types of grinding discs can be quickly switched according to actual needs, increasing the adaptability and flexibility of the equipment and meeting different processing requirements.

[0021] Working principle: During the sanding process, the movement of the chip collection box 181 will drive the movement of the fixed rod 191, which in turn drives the pressure plate 192 to move. The downward movement of the elastic rod 193 will drive the pressure plate 192 to move downward. The downward movement of the pressure plate 192 will compact the wood chips stored inside the chip collection box 181, thus facilitating the later recycling and utilization of the wood chips. When the sanding plate 11 needs to be replaced due to prolonged use, the screw 1910 will be rotated by turning the knob. The rotation of the screw 1910 will move upward through the threaded groove inside the fixed block 199, and then disengage from the fixed block 199, thus quickly completing the replacement of the sanding plate 11 and reducing downtime.
