Description

Technical Field

[0001] This invention relates to the field of panel sanding and processing, and more particularly to a sanding device for processing furniture panels. Background Technology

[0002] In furniture manufacturing, sanding effectively removes oxide scale, oil stains, and rough fibers from the surface of wood boards, preventing poor penetration of paint or varnish and thus significantly improving the adhesion and surface smoothness of the finished product. Furthermore, the surface treatment of curved wood boards, such as table legs and stair railings, is particularly crucial. Meticulous sanding not only determines the visual appeal of the finished product but also directly affects its lifespan. Traditional sanding machines are primarily designed for flat surfaces and struggle to quickly adapt to round or irregular edges. When sanding the curved structures at both ends of the circumferential sides of a wood board, robotic arms are required to repeatedly flip and adjust the angle, resulting in low sanding efficiency. While manual sanding is flexible, it presents serious safety hazards and low efficiency. Manual sanding requires repeated use of coarse and fine sandpaper, is physically demanding, and can easily lead to hand abrasions and injuries for workers. It also makes it difficult to maintain the stability of the curvature. Therefore, developing an automated sanding technology that can efficiently, safely, and precisely process the curved areas at both ends of wood boards has become key to solving the current pain points in furniture wood board processing. Summary of the Invention

[0003] In order to overcome the shortcomings of traditional sanders in sanding wood boards with rounded ends, which are inefficient and pose a risk of injury when sanding manually, this invention provides a sanding device for furniture board processing.

[0014] This invention discloses a sanding device for processing furniture boards. A conveyor belt sequentially transports the wood board to be sanded to two grinding wheels.

The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0026] Example 1: A sanding device for processing furniture panels, such as... Figures 1-7As shown, the assembly includes an installation machine tool 1, a conveyor belt 11, a limiting plate 12, a guide ramp 13, a lower clamping block 21, a first electric lift 22, a lower clamping block 23, a first electric push rod 24, a fixing block 31, a transverse slider 32, an electric telescopic rod 33, a grinding wheel 34, a motor 341, a power gear 342, and a transmission gear 343. The conveyor belt 11 is wound around the conveyor component of the installation machine tool 1. Several limiting plates 12 are fixedly connected to the conveyor belt 11. A guide ramp 13 is fixedly connected to the left and right sides of the installation machine tool 1. A lower clamping block 21 is slidably connected to the left and right sides of the installation machine tool 1. A first electric lift 22, which moves up and down, is installed on the installation machine tool 1. The telescopic ends of the two first electric lifts 22 are respectively fixedly connected to corresponding lower clamping blocks 21. A lower clamping block 23 is slidably connected to each of the two lower clamping blocks 21. Clamping block 23; each of the two lower clamping blocks 21 is equipped with a first electric push rod 24; the telescopic ends of the two first electric push rods 24 are respectively fixed to the corresponding lower clamping blocks 23; a fixing block 31 is fixed to the left and right sides of the machine tool 1; a transverse slider 32 is slidably connected to each of the two fixing blocks 31; an electric telescopic rod 33 is installed on each of the two fixing blocks 31; the telescopic ends of the two electric telescopic rods 33 are respectively fixed to the corresponding transverse sliders 32; a grinding wheel 34 is rotatably connected to each of the two transverse sliders 32, and the grinding wheel 34 is located above the lower clamping block 21; a motor 341 is installed on each of the two transverse sliders 32; a power gear 342 is fixed to the output shaft of each of the two motors 341; a transmission gear 343 is fixed to each of the two grinding wheels 34; the two power gears 342 mesh with the transmission gears 343 on the same side respectively.

[0027] like Figure 5 As shown, an upper clamping block 25 is slidably connected to the mounting machine tool 1; an upper clamping block 26 is slidably connected to the upper clamping block 25; a second electric push rod 27 is mounted on the upper clamping block 25; the telescopic end of the second electric push rod 27 is fixedly connected to the upper clamping block 26; a second electric lifting mechanism 28 is mounted on the mounting machine tool 1; the telescopic end of the second electric lifting mechanism 28 is fixedly connected to the upper clamping block 25.

[0028] Workers vertically insert wooden boards 6 between the limiting plates 12 of the conveyor belt 11 one by one. The arc structure at both ends of the circumferential side of the wooden board 6 faces the left and right sides respectively. The installation machine tool 1 controls the conveyor belt 11 and the limiting plates 12 to convey the wooden boards 6 one by one under the two grinding wheels 34. When the wooden board 6 passes the guide ramps 13 on the left and right sides, the wooden board 6 is adjusted to be aligned with the middle position of the conveyor belt 11 under the guidance of the two guide ramps 13.

[0029] After the wooden board 6 is conveyed to the area below the two grinding wheels 34, the installation machine tool 1 stops driving the control conveyor belt 11. The first electric lifters 22 on both sides push the lower clamping blocks 21 connected to them upward to lift the wooden board 6. At the same time, the first electric push rod 24 pulls the lower clamping block 23 to push the wooden board 6 toward the corresponding lower clamping block 21. The lower clamping block 23 and the lower clamping block 21 work together to hold the bottom of the wooden board 6. Then, the first electric lifter 22 pushes the lower clamping block 21 to move the wooden board 6 slowly upward. At the same time, the motor 341 drives the power gear 342 to rotate. The power gear 342 meshes with the transmission gear 343 to drive the grinding wheel 34 to rotate until the upper surface of the wooden board 6 on the side contacts the grinding wheel 34. The electric telescopic rod 33 controls the horizontal slider 32 to drive the grinding wheel 34 to move laterally in the left and right direction on the upper surface of the wooden board 6 on the side, so as to polish and grind the upper surface of the wooden board 6 on the side.

[0030] Then, the electric telescopic rod 33 controls the horizontal slider 32 to move the grinding wheel 34 to the upper surface of the arc structure circumferentially on the side of the wooden board 6. The first electric lift 22 continues to push the lower locking block 21 to move the wooden board 6 slowly upward. At the same time, the electric telescopic rod 33 controls the horizontal slider 32 to move the grinding wheel 34 laterally in the left and right directions, so that the grinding wheel 34 keeps in contact with the arc structure circumferentially on the side of the wooden board 6 for continuous grinding, thereby polishing the arc structure circumferentially on the side of the wooden board 6.

[0031] Finally, the first electric lift 22 pushes the lower clamping block 21 to move the wooden board 6 upward to contact the upper clamping block 25. The second electric push rod 27 pulls the upper clamping block 26 to push the wooden board 6 towards the corresponding upper clamping block 25. The upper clamping block 26 and the upper clamping block 25 work together to hold the top of the wooden board 6. The first electric push rod 24 then pulls the lower clamping block 23 to move in the opposite direction to release the wooden board 6. The first electric lift 22 pulls the lower clamping block 21 downward to leave the wooden board 6. Then, the electric telescopic rod 33 controls the horizontal slider 32 to drive the grinding wheel 34 to move laterally in the left and right direction on the lower surface of the circumferential side of the wooden board 6, so as to polish and grind the lower surface of the circumferential side of the wooden board 6. The entire grinding process does not require flipping the wooden board 6 or manual intervention, and the sanding and grinding of the wooden board 6 is completed quickly.

[0032] like Figure 7As shown, both grinding wheels 34 have hollow cavities; each grinding wheel 34 has several through holes 3401 on its outer surface that connect to the hollow cavities; each of the two transverse sliders 32 has a gas valve 35 fixedly connected to it, and the gas valve 35 is connected to a high-pressure airflow conveying device; the two gas valves 35 are rotatably connected to the front end of the corresponding grinding wheel 34, and the gas valves 35 connect to the hollow cavities of the corresponding grinding wheel 34; each of the two grinding wheels 34 has several grooves 3402 on its outer surface, and the through holes... Structure 3401 is located in the corresponding groove structure 3402, which prevents the through hole structure 3401 of the grinding wheel 34 from directly contacting the sanding area of ​​the wooden board 6, thereby preventing the through hole structure 3401 of the grinding wheel 34 from participating in continuous sanding work and causing structural damage; each of the two transverse sliders 32 is fixedly connected to an infusion valve 36, and the infusion valve 36 is externally connected to a lubricating fluid delivery device; the two infusion valves 36 are respectively rotatably connected to the rear end of the corresponding grinding wheel 34, and the infusion valve 36 is connected to the hollow cavity structure of the corresponding grinding wheel 34.

[0033] During the routine sanding process on the wooden board 6, the air supply valve 35 is in the open state and the liquid supply valve 36 is in the closed state. The external high-pressure air supply equipment continuously supplies high-pressure air to the hollow cavity structure of the grinding wheel 34 through the air supply valve 35. The high-pressure air is continuously ejected outward through the through hole structure 3401 of the grinding wheel 34. The high-pressure air ejected from the through hole structure 3401 promptly blows away the debris generated by the grinding wheel 34 on the wooden board 6. At the same time, the high-pressure air carries away the heat generated in the sanded area of ​​the wooden board 6, performing air cooling treatment on the wooden board 6 to avoid local abnormal high temperature and discoloration caused by the wooden board 6.

[0034] When it is necessary to increase the grinding intensity of the grinding wheel 34 on the wooden board 6 and further improve the surface smoothness of the wooden board 6, the motor 341 increases the rotation speed of the grinding wheel 34. At this time, the grinding wheel 34 will generate more heat when grinding continuously on the wooden board 6. At this time, the air supply valve 35 switches to the closed state, the liquid supply valve 36 switches to the open state, the external high-pressure air supply equipment is closed, and the external lubricant supply equipment continuously supplies lubricant into the hollow cavity structure of the grinding wheel 34 through the air supply valve 35. The lubricant is continuously sprayed outward through the through hole structure 3401 of the grinding wheel 34 onto the grinding wheel 34 and the wooden board 6. The continuously sprayed lubricant enhances the cooling effect on the wooden board 6 and avoids local abnormal high temperature on the wooden board 6, which may cause discoloration or even burning.

[0035] Compared to using a traditional, complete grinding wheel to sand the wood board 6, and using a traditional spray pipe to spray coolant onto the surface of the wood board 6, in this embodiment, the high-speed rotating grinding wheel 34 continuously sprays lubricant onto the surface of the wood board 6 through the through-hole structure 3401 during sanding. The heat absorption properties of the lubricant enhance the cooling effect on the wood board 6. During this process, the lubricant continuously sprayed from the through-hole structure 3401 accumulates between the groove structure 3402 and the surface of the wood board 6. As the grinding wheel 34 rotates, it pushes the lubricant accumulated in the groove structure 3402 to directly coat the surface of the wood board 6, allowing... The lubricant can be spread more evenly on the surface of the wooden board 6, avoiding the phenomenon of a large amount of lubricant splashing and scattering on the surface of the wooden board 6 when using a traditional spray pipe to directly spray lubricant onto the surface of the wooden board 6. The continuous splashing of lubricant sprayed by the traditional spray pipe on the surface of the wooden board 6 will destroy the uniformity of the lubricant coating on the surface of the wooden board 6, resulting in the area of ​​the wooden board 6 in contact with the grinding wheel not being effectively coated with lubricant, thus destroying the lubricating and cooling effect of the lubricant on the surface of the wooden board 6. This embodiment overcomes the above problems by using the method of pushing the lubricant accumulated in the groove structure 3402 onto the surface of the wooden board 6, thereby enhancing the lubricating and cooling effect of the lubricant on the surface of the wooden board 6.

[0036] When the high-speed rotating grinding wheel 34 sands the wooden board 6, a large number of wood chips of varying sizes will adhere to the surface of the wooden board 6. Due to the viscosity of the lubricating fluid, most of the small wood chips can be adhered to the liquid and carried away. However, some large wood chips will remain on the surface of the wooden board 6, hindering the sanding process of the grinding wheel 34. In this embodiment, when the rotating grinding wheel 34 pushes the lubricating fluid accumulated in the groove structure 3402 to flow along the surface of the wooden board 6, the accumulated lubricating fluid will flow in a wave-like state with a certain thickness through the area on the surface of the wooden board 6 where large wood chips remain. The continuously generated wave-like lubricating fluid will continuously beat the large wood chips remaining on the surface of the wooden board 6, continuously pushing them away from the area on the surface of the wooden board 6 where sanding is being carried out, thus avoiding the large wood chips from hindering the sanding process of the grinding wheel 34.

[0037] Example 2, as Figures 1-8 As shown, based on the above embodiment 1, each of the two transverse sliders 32 in this embodiment is rotatably connected to a baffle 41 that covers the outside of the corresponding grinding wheel 34; both baffles 41 are C-shaped plate structures with the opening area facing downward; two torsion springs 42 are fixed between each of the two baffles 41 and the corresponding transverse slider 32; and a push plate 43 is fixed to each of the opposing sides of the bottom of the two baffles 41.

[0038] When the lower clamping block 23 lifts the wooden board 6 upwards until it contacts the bottom of the grinding wheel 34, the push plate 43 is pressed tightly against the upper surface of the wooden board 6, and the opening area of ​​the C-shaped plate structure of the baffle 41 faces the surface of the wooden board 6. As the grinding wheel 34 moves downwards along the arc of the wooden board 6, the push plate 43 is blocked by the wooden board 6 and pushes the baffle 41 upwards. The baffle 41 drives the torsion spring 42 to twist, keeping the opening area of ​​the C-shaped plate structure of the baffle 41 facing the surface of the wooden board 6. This ensures that the grinding contact surface between the grinding wheel 34 and the wooden board 6 is not blocked by the baffle 41, while ensuring that the baffle 41 surrounds the outside of the non-grinding area of ​​the grinding wheel 34, allowing light to pass through the non-grinding area of ​​the grinding wheel 34. The lubricant flowing out of the hole structure 3401 accumulates between the groove structure 3402 and the baffle 41 until the grinding wheel 34 rotates to contact the surface of the wood board 6. This prevents the lubricant flowing out of the hole structure 3401 from being flung around during the sanding process, thus avoiding a large waste of lubricant. When the lubricant accumulated in the groove structure 3402 of the grinding wheel 34 rotates to contact the surface of the wood board 6, the accumulated lubricant can be coated onto the surface of the wood board 6 by the rotating grinding wheel 34 in the manner described in the above embodiment. The wave-like lubricant pushes large wood chips away from the area of ​​the wood board 6 that is being sanded.

[0039] Example 3, as Figures 1-8 As shown, based on the above embodiment 2, each of the two baffles 41 in this embodiment is fixedly connected to a spray pipe 5, and the spray pipe 5 is externally connected to a filling adhesive conveying device; both spray pipes 5 are provided with a plurality of spray hole structures 501 facing the corresponding grinding wheel 34; the mounting machine tool 1 is provided with a hollow groove structure 101; the conveyor belt 11 is provided with a plurality of hollow groove structures 1101 aligned with the hollow groove structure 101; a waste liquid tank 14 aligned with the hollow groove structure 101 is provided below the mounting machine tool 1.

[0040] During the sanding process of the abrasive wheel 34 on the circumferential side area of ​​the wood board 6 according to the steps of the above embodiment, the external filler adhesive delivery device continuously delivers filler adhesive to the spray pipe 5. The filler adhesive is sprayed out through the spray hole structure 501 of the spray pipe 5 onto the sanding contact surface between the abrasive wheel 34 and the wood board 6. The friction of the abrasive wheel 34 is used to press the filler adhesive into the fine pores of the wood board 6, thereby sealing the pores of the wood board 6, making the surface of the wood board 6 smoother and allowing the paint film to adhere more firmly. The filler adhesive used in this embodiment is a mixture of fine wood powder and alkyd resin. It can be formulated to produce fillers with a color similar to that of the wood board 6, such as light oak and dark walnut, to achieve the effect of disguising pores. It is often used in furniture that pursues a high-gloss polishing effect.

[0041] As the grinding wheel 34 continuously moves and changes its grinding angle on the wooden board 6, the push plate 43 is blocked by the wooden board 6, pushing the baffle 41 to follow the grinding wheel 34 and continuously change its rotation angle. This ensures that the angle at which the filler adhesive is sprayed from the nozzle structure 501 always faces the grinding contact surface between the grinding wheel 34 and the wooden board 6, allowing the filler adhesive to be smoothly pressed into the fine holes in various parts of the circumferential side area of ​​the wooden board 6. Excess filler adhesive falls down into the waste liquid tank 14 for recycling through the hollow groove structure 1101 of the conveyor belt 11 and the hollow groove structure 101 of the mounting machine tool 1. During this period, only the air supply valve 35 can be opened to supply high-pressure airflow, while the liquid supply valve 36 remains closed to prevent the lubricant supplied by the liquid supply valve 36 from mixing with the filler adhesive sprayed from the spray pipe 5. When the grinding wheel 34 presses the filler adhesive into the fine holes of the wooden board 6, excess filler adhesive on the surface of the wooden board 6 enters the groove structure 3402 of the grinding wheel 34. When the grinding wheel 34 rotates, it uses the groove structure 3402 to push the excess filler adhesive away from the pressure area of ​​the wooden board 6 and remove it, avoiding the accumulation of thick filler adhesive in local areas on the surface of the wooden board 6. Through the removal of excess filler adhesive by the groove structure 3402, the filler adhesive is evenly pressed onto the surface of the wooden board 6, improving the smoothness of the surface of the wooden board 6. Moreover, because the filler adhesive is removed in time, it will not directly accumulate on the surface of the grinding wheel 34 and the surface of the wooden board 6, and the frictional resistance of the grinding wheel 34 during operation is significantly reduced, thereby reducing the generation of heat.
