Description

Technical Field

[0001] This invention relates to the field of board sanding technology, specifically to an end-face sanding device for furniture manufacturing boards. Background Technology

[0002] Boards are sheet-like materials made primarily from wood through processes such as machining, gluing, hot pressing, and cold pressing. They are widely used in furniture manufacturing and other fields. Before furniture manufacturing, the ends of the boards need to be sanded.

[0003] Existing sanding mechanisms have weak capabilities in handling hard knots when sanding the end faces of boards. The end faces of wood boards often contain hard knots such as natural wood knots, resin lumps, hard sawdust clumps, and hardened adhesive lumps. Existing equipment typically uses sanding wheels that directly contact these hard knots, and the rigid impact load can easily cause the sanding wheels to chip or wear unevenly. Vibration transmitted to the board can also induce the propagation of microcracks. Furthermore, the efficiency of removing hard knots is difficult to balance with that of removing regular areas, requiring manual shutdowns for processing, which severely impacts processing continuity. In practical applications, existing board end face sanding equipment also suffers from limitations. The existing cooling mechanism cannot adapt to the heat dissipation requirements of different sanding conditions. The heat generation in the coarse and fine sanding stages is significantly different. In the coarse sanding stage, the friction between the sanding wheel and the board is intense and generates a lot of heat, requiring strong cooling capacity. In the fine sanding stage, the friction is weak and the heat generation is small. Excessive cooling will affect the sanding smoothness. The existing cooling mechanism cannot improve the cooling intensity in a targeted manner and only adopts a fixed cooling mode. Either the sanding wheel will overheat and wear due to insufficient cooling and the end face of the board will be thermally deformed, or the wood fibers will become damp due to excessive cooling and the sanding precision will decrease. Summary of the Invention

An exhaust fan is installed inside the exhaust pipe, and a nozzle is fixedly connected to the end of the exhaust pipe. A sliding plate is slidably connected to the nozzle, and a lower hole and an upper hole are opened on the sliding plate. A back spring is fixedly connected to the outer side wall of the sliding plate, and the other end of the back spring is fixedly connected to the outer side wall of the nozzle. A wedge is fixedly connected to the end of the sliding plate away from the lower hole.

[0006] Preferably, a bottom component is fixedly connected to the outer wall of the water tank, a rack is slidably connected to the bottom component, a magnetic strip is fixedly connected to the end of the rack, a return spring is fixedly connected to the outer wall of the rack, the other end of the return spring is fixedly connected to the outer wall of the bottom component, a gear is fixedly sleeved at one end of the rotating rod located outside the water tank, the rack and the gear are meshed, and a pressing component is fixedly connected to the outer wall of the rack, the pressing component is located on the right side of the wedge-shaped component.

[0007] Preferably, a turntable is installed on the outer wall of the coarse grinding wheel, and multiple slide rails are provided on the turntable. Magnetic blocks are slidably connected inside the multiple slide rails. A tension spring is fixedly connected to the outer wall of the magnetic block, and the end of the tension spring away from the magnetic block is fixedly connected to the inner wall of the slide rail.

[0008] Preferably, a bottom cylinder is fixedly connected to the outer wall of the cross plate, a sliding rod is slidably connected to the bottom cylinder, a return spring is sleeved on the outer wall of the sliding rod, and a hard knot processing mechanism is provided at the end of the sliding rod.

[0009] Preferably, the hard node treatment mechanism includes a fixed frame fixedly connected to the end of the sliding rod, a locator is provided inside the fixed frame, a scraper is slidably connected to the fixed frame, a pressure spring is fixedly connected to the outer wall of the scraper, and the end of the pressure spring away from the scraper is fixedly connected to the fixed frame.

[0010] Preferably, the fixed frame has a storage slot inside, a push switch is fixedly connected inside the storage slot, a bottom mounting piece is fixedly connected to the fixed frame, electric telescopic rods are fixedly connected to both sides of the bottom mounting piece, and a cutter is fixedly connected to the ends of the two electric telescopic rods.

[0011] Preferably, multiple upper positioning parts and bottom positioning parts are fixedly connected to the outer side wall of the main body of the equipment. Plates are installed on the main body of the equipment. A chip collection box is fixedly connected to the outer side wall of the side plate. A chip suction pipe is connected to the chip collection box, and a suction pump is installed inside the chip suction pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a drive mechanism to fix the frame and scraper, performing burr removal pretreatment on the end face of the board before grinding. This effectively removes irregular sharp-angle burrs and transforms the contact form of the subsequent grinding load from point contact to continuous surface contact, making the edge stress distribution more uniform and reducing the probability of edge chipping and cracking from the source. At the same time, the hard knot processing mechanism can quickly identify hard knots such as wood knots and resin lumps on the end face of the board and remove them with a cutter, achieving automated removal of hard knots without manual intervention. For the removed area, a low-pressure high-speed grinding mode is adopted. This reduces the contact pressure to avoid rigid impact between the coarse grinding wheel and the hard knot, reducing tooth chipping and uneven grinding. It also compensates for the insufficient cutting depth of low pressure by increasing the abrasive cutting frequency, ensuring that the grinding efficiency of the hard knot area is consistent with that of the regular area, guaranteeing processing continuity and equipment lifespan.

[0013] 2. This invention can adaptively adjust the cooling mode according to different sanding stages to achieve precise cooling. It is highly practical. During regular rough sanding, the gas-liquid mixing cooling is automatically activated, with cooling water mixed with the airflow at a flow rate of 5 drops per second to cool the wood, taking into account both heat dissipation and prevention of wood from getting damp. During high-speed rough sanding of hard knots, centrifugal force drives the cooling flow rate to increase to 10 drops per second, and the conical airflow channel is switched to enhance cooling, avoiding damage to the rough sanding wheel and chipping of the board caused by high temperature. During fine sanding, the liquid cooling is automatically turned off, and only air cooling is used to meet the low heat dissipation requirements, avoiding excessive cooling that affects the surface finish. No manual intervention is required throughout the process. The structure is simplified, taking into account both processing quality and equipment stability, and adapting to sanding needs under various working conditions. Attached Figure Description

Large capillary pores 35 and small capillary pores 34 are opened inside the two dripping holes, respectively.

[0018] A horizontal plate 21 is fixedly connected to the outer wall of the side plate 9. An exhaust pipe 22 is fixedly connected to the horizontal plate 21. An exhaust fan is installed inside the exhaust pipe 22. A nozzle 23 is fixedly connected to the end of the exhaust pipe 22. A sliding plate 50 is slidably connected to the nozzle 23. A lower hole 30 and an upper hole 31 are provided on the sliding plate 50. A back spring 49 is fixedly connected to the outer wall of the sliding plate 50. The other end of the back spring 49 is fixedly connected to the outer wall of the nozzle 23. A wedge-shaped piece 32 is fixedly connected to the end of the sliding plate 50 away from the lower hole 30.

[0019] A bottom component 18 is fixedly connected to the outer wall of the water tank 20. A rack 48 is slidably connected to the bottom component 18. A magnetic strip 17 is fixedly connected to the end of the rack 48. A return spring 19 is fixedly connected to the outer wall of the rack 48. The other end of the return spring 19 is fixedly connected to the outer wall of the bottom component 18. A gear 29 is fixedly sleeved at one end of the rotating rod 28 located outside the water tank 20. The rack 48 and the gear 29 are meshed. A pressing member 33 is fixedly connected to the outer wall of the rack 48. The pressing member 33 is located to the side of the wedge-shaped member 32.

[0020] A turntable 14 is installed on the outer wall of the coarse grinding wheel 11. Multiple slide rails 13 are provided on the turntable 14. Magnetic blocks 15 are slidably connected inside the multiple slide rails 13. A tension spring 16 is fixedly connected to the outer wall of the magnetic block 15. The end of the tension spring 16 away from the magnetic block 15 is fixedly connected to the inner wall of the slide rail 13.

[0021] A bottom cylinder 45 is fixedly connected to the outer wall of the horizontal plate 21. A sliding rod 36 is slidably connected to the bottom cylinder 45. A return spring 37 is sleeved on the outer wall of the sliding rod 36. A hard knot processing mechanism is provided at the end of the sliding rod 36.

[0022] The hard node processing mechanism includes a fixed frame 38 fixedly connected to the end of the sliding rod 36. A locator is provided inside the fixed frame 38. A scraper 39 is slidably connected to the fixed frame 38. A pressure spring 46 is fixedly connected to the outer wall of the scraper 39. The end of the pressure spring 46 away from the scraper 39 is fixedly connected to the fixed frame 38.

[0023] In this embodiment, at the initial stage of processing, the plate 4 to be processed is placed on the main body 1 of the equipment. The upper positioning component 2 and the bottom positioning component 3 form a linkage clamping mechanism, which quickly completes the positioning and clamping from both sides to ensure that the plate 4 does not deviate during the subsequent processing. Then, under the driving action of the drive rail 5, the drive component 6 moves along the rail from left to right. When the drive component 6 moves, the fixed frame 38 moves synchronously with it and contacts the end face of the plate 4. During this process, the scraper 39 removes the burrs on the end face of the plate 4. By removing the irregular sharp-angle burrs on the edge of the end face, the contact form of the subsequent grinding load is changed from point contact to continuous surface contact, so that the edge stress distribution is more uniform and the plate 4 is prevented from chipping.

[0024] When the drive component 6 moves the coarse grinding wheel 11 to the end face of the plate 4, the horizontal telescopic rod 8 is extended to make the coarse grinding wheel 11 fit against the end face of the plate 4. After fitting, the dual-axis motor 10 drives the coarse grinding wheel 11 to rotate and perform coarse grinding on the end face of the plate 4. While the coarse grinding wheel 11 rotates, it will drive the turntable 14 to rotate synchronously. The centrifugal force generated by the rotation causes the magnetic block 15 to overcome the tension of the tension spring 16 and move to the outside of the turntable 14, reducing the distance between the magnetic block 15 and the magnetic strip 17. The magnetic repulsion force generated by the two overcomes the elastic force of the return spring 19 and pushes the rack 48 to move slightly away from the turntable 14.

[0025] Because rack 48 meshes with gear 29, when rack 48 moves slightly, it drives rotating rod 28 and blocking disk 27 to rotate 180 degrees via gear 29. After the blocking disk 27 rotates, the small capillary pores 34 on it move exactly above the dripping pipe 26. The opening end of the dripping pipe 26, which was originally closed by the non-porous area of ​​the blocking disk 27, is now open by the small capillary pores 34. At this time, the cooling water in the water tank 20 is injected into the dripping pipe 26 through the small capillary pores 34 at a flow rate of 5 drops per second. The droplets naturally fall to the bottom of the dripping pipe 26. The liquid is broken into small droplets by the mesh 47 and drips onto the side of the nozzle 23. At the same time, the exhaust fan built into the exhaust pipe 22 draws in external air and blows it out quickly through the lower hole 30 of the nozzle 23. After mixing with the small droplets, the air is blown at a 15-degree angle to the sanding contact area between the coarse grinding wheel 11 and the board 4, thereby cooling the coarse grinding wheel 11. It should be noted that the smaller droplets mixed with the airflow will be instantly evaporated by the high temperature after contacting the sanding area between the coarse grinding wheel 11 and the board 4, and will not penetrate into the wood fibers.

[0026] Example 2: Please refer to Figure 1 - Figure 14 This embodiment further describes Example 1. The fixed frame 38 has a storage groove 44 inside, and a push switch 43 is fixedly connected inside the storage groove 44. A bottom mounting piece 40 is fixedly connected to the fixed frame 38, and electric telescopic rods 42 are fixedly connected to both sides of the bottom mounting piece 40. A cutter 41 is fixedly connected to the ends of the two electric telescopic rods 42.

[0027] Multiple upper positioning parts 2 and bottom positioning parts 3 are fixedly connected to the outer side wall of the main body 1 of the equipment. A plate 4 is installed on the main body 1 of the equipment. A chip collection box 24 is fixedly connected to the outer side wall of the side plate 9. A chip suction pipe 25 is connected to the chip collection box 24. A suction pump is installed inside the chip suction pipe 25.

[0028] In this embodiment, the fixed frame 38 moves with the drive component 6. When the scraper 39 removes burrs from the unsanded area, if there are hard knots such as natural wood knots, resin lumps, uncrushed hard wood chips, or hardened adhesive blocks on the end face of the board 4, the scraper 39 will be blocked by the hard knots and remain stationary. Since the fixed frame 38 is continuously pushed by the drive component 6, the bottom cylinder 45, the sliding rod 36 and other mechanisms, the stationary scraper 39 will enter the storage groove 44 during the movement of the fixed frame 38 and touch the press switch 43.

[0029] After the press switch 43 is triggered, the drive rail 5 immediately stops driving the drive component 6, bringing it to a standstill. At the same time, the transverse telescopic rod 8 retracts, causing the coarse grinding wheel 11 to disengage from the end face of the plate 4. Subsequently, the two electric telescopic rods 42 extend, pushing the cutter 41 to move from bottom to top to remove the hard nodules. After the removal is completed, the electric telescopic rods 42 drive the cutter 41 to reset, and the scraper 39 returns to its original position under the action of the pressure spring 46. The locator in the fixed frame 38 marks the hard nodule cutting area and transmits the coordinates to the control system of the drive rail 5. After receiving the coordinates, the drive rail 5 restarts driving the drive component 6 to move, and the transverse telescopic rod 8 extends again to make the coarse grinding wheel 11 fit against the end face of the plate 4. This is existing technology and will not be elaborated further.

[0030] When the drive component 6 moves the coarse grinding wheel 11 to the hard point cutting area, the transverse telescopic rod 8 retracts 0.5 mm to reduce the contact pressure between the coarse grinding wheel 11 and the end face of the plate 4. Under low contact pressure, the dual-axis motor 10 drives the coarse grinding wheel 11 to rotate at high speed. By grinding the hard point cutting area at low pressure and high speed with the coarse grinding wheel 11, the rigid impact load between the coarse grinding wheel 11 and the hard point can be greatly reduced, avoiding the tooth breakage, uneven wear and vibration transmission of the coarse grinding wheel 11 caused by conventional high pressure grinding. At the same time, it suppresses the propagation of microcracks and end face chipping caused by stress concentration. High-speed grinding compensates for the insufficient cutting depth of a single abrasive grain caused by low pressure by increasing the abrasive grain cutting frequency, ensuring that the hard point removal efficiency is consistent with that of the conventional area.

[0031] When the coarse grinding wheel 11 rotates at high speed, the turntable 14 rotates synchronously at high speed, generating a greater centrifugal force than during conventional coarse grinding. This causes the magnetic block 15 to overcome the tension of the tension spring 16 and move a greater distance to the outside of the turntable 14, increasing the magnetic repulsion with the magnetic strip 17. This pushes the rack 48 to move further away from the coarse grinding wheel 11 based on the initial displacement. The rack 48 drives the gear 29 to rotate, causing the rotating rod 28 and the blocking disc 27 to rotate another 90 degrees on top of the original 180-degree rotation. At this time, the large capillary orifice 35 moves to the inlet end of the dripping pipe 26. Because the diameter of the large capillary orifice 35 is larger than that of the small capillary orifice 34, the flow rate of cooling water injected into the dripping pipe 26 through the large capillary orifice 35 increases to 10 drops per second. After being broken by the crushing net 47, the water drips to the side of the nozzle 23.

[0032] At the same time, when the rack 48 moves significantly, it will drive the pressing part 33 to move synchronously. During the movement, the pressing part 33 will press down the slide plate 50 along the contact slope of the wedge 32, so that the upper hole 31 replaces the lower hole 30 and enters the nozzle 23. Since the upper hole 31 is a conical structure, the high-speed airflow blown out by the exhaust pipe 22 will accelerate after passing through the conical guide and mix with more fine droplets before being blown towards the grinding contact area. The cooling capacity is significantly improved, meeting the cooling requirements of the hard knot area of ​​the high-speed grinding wheel 11.

[0033] After the coarse grinding wheel 11 leaves the hard-nodal cutting area, a 5-10 mm gradual transition section is set. Within the transition section, the transverse telescopic rod 8 slowly extends, so that the coarse grinding wheel 11 restores the normal contact pressure with the end face of the plate 4. The dual-axis motor 10 synchronously adjusts the speed of the coarse grinding wheel 11 to the normal value.

[0034] After the first rough grinding of the end face of the board 4 is completed, the horizontal telescopic rod 8 retracts, causing the coarse grinding wheel 11 to disengage from the end face. The drive rail 5 will return the coarse grinding wheel 11 and other mechanisms to their initial position through the drive component 6. At this time, the operator controls the longitudinal telescopic rod 7 to extend, allowing the fine grinding wheel 12 to move upward and replace the coarse grinding wheel 11 to fit against the end face of the board 4. The above movement process is repeated, and the drive component 6 moves from left to right along the drive rail 5 again, and the fine grinding wheel 12 rotates synchronously to perform fine grinding on the end face of the board 4.

[0035] When the fine grinding wheel 12 is grinding, the rack 48 is not driven by magnetic force and remains in place. The blocking disc 27 closes the drip pipe 26, so no cooling water drips. The exhaust pipe 22 cools the fine grinding wheel 12 only through airflow. Because the friction between the fine grinding wheel 12 and the end face of the board 4 is less than that of the coarse grinding wheel 11, less frictional heat is generated. Airflow cooling alone is sufficient to meet the requirements and avoids excessive cooling that may affect the grinding effect.

[0036] Additional notes: The water tank 20 is equipped with a filling port, which can be used to replenish the cooling water when it is depleted; the debris generated by the grinding wheel 12 and the coarse grinding wheel 11 is sucked into the chip collection box 24 by the chip suction pipe 25 for centralized collection. The drive rail 5 has built-in mover and stator windings, which drive the drive component 6 to move along the rail through electromagnetic induction, resulting in high positioning accuracy and fast response speed (this is existing technology and will not be elaborated further).
