[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1-10A wood furniture sanding device includes a processing box 1 with a transparent glass observation window for timely observation of the sanding process. The processing box 1 has two clamping frames 5 with openings for mounting them. A first hydraulic cylinder 7 is fixedly mounted on the processing box 1. One clamping frame 5 is fixedly connected to the drive end of the first hydraulic cylinder 7, and the other clamping frame 5 is fixedly connected to the processing box 1. Multiple rotating components are mounted on the two clamping frames 5. Each rotating component is used for sanding the sides of the wood furniture. Each sanding component includes a rotating shaft 26 rotatably mounted on the clamping frame 5, with a sanding roller 22 fixedly connected to the rotating shaft 26. Each clamping frame 5 has a positioning plate 17 with an L-shaped cross-section fixedly connected to it.

[0036] A first motor is fixedly installed on the processing box 1. A reciprocating lead screw 8 is fixedly connected to the drive end of the first motor. A support block 10 is threadedly connected to the reciprocating lead screw 8. A lifting assembly is set above the support block 10. The lifting assembly includes a second hydraulic cylinder 6 fixedly installed on the support block 10. A support plate 15 is fixedly connected to the drive end of the second hydraulic cylinder 6. Multiple second motors are fixedly installed on the support plate 15. A grinding head 9 is fixedly connected to the drive end of each second motor.

[0037] Each clamping frame 5 has an L-shaped support 21 fixedly connected to its lower surface. Multiple L-shaped slide rods 19 are slidably connected to the support 21. Each slide rod 19 has an arc-shaped block 20 fixedly connected to its lower end, which works in conjunction with the pressing rod 16. The arc-shaped block 20 has a semi-circular cross-section. Multiple pressing rods 16 are fixedly connected to the upper surface of the support plate 15. The multiple pressing rods 16 are symmetrically arranged. As each pressing rod 16 moves along the reciprocating screw 8 with the support plate 15, it will move against the arc-shaped surface of the arc-shaped block 20, causing the arc-shaped block 20 to move upward, which in turn drives the slide rod 19 and the slider 24 to move upward together.

[0038] Each slider 19 is slidably connected to a slider 24. A first spring 28 is fixedly connected to the lower surface of the slider 24. The first spring 28 is fixedly connected to the surface of the bracket 21. A second spring 25 is sleeved on the slider 19. One end of the second spring 25 is fixedly connected to the slider 19, and the other end of the second spring 25 is fixedly connected to the upper surface of the slider 24. Multiple airbags 30 are fixedly connected to the bracket 21. Each airbag 30 is in contact with the surface of the slider 24. Each slider 24 is provided with a groove 31. An extrusion piece 29 is slidably connected in the groove 31. A hinge rod 27 is hinged to the extrusion piece 29. The end of the hinge rod 27 away from the extrusion piece 29 is hinged to the slider 19.

[0039] Each rotating shaft 26 has multiple rotating pieces 18 fixedly connected to one end of the clamping frame 5. The multiple rotating pieces 18 are equidistant. Since the spring coefficient of the second spring 25 is larger than that of the first spring 28, the first spring 28 undergoes tensile deformation during the upward movement of the slider 24. In the initial state, the extrusion piece 29 is located below the rotating piece 18. When the tensile deformation of the first spring 28 reaches its maximum, the upper end of the extrusion piece 29 moves up to between two adjacent rotating pieces 18. As the arc block 20 continues to move upward, the slide rod 19 will slide relative to the slider 24, the second spring 25 will deform, and the tilt angle of the hinge rod 27 will change simultaneously, causing the extrusion piece 29 and the slider 24 to slide relative to each other.

[0040] A cam 12 is fixedly connected to one end of a reciprocating lead screw 8 that passes through the machining box 1. A moving block 13 with a T-shaped cross-section is slidably connected to the machining box 1. The moving block 13 is located directly below the cam 12. Two symmetrically arranged support rods 11 are slidably connected to the machining box 1. A rotating rod 14 is hinged to each support rod 11. The rotating rod 14 is hinged to the moving block 13. A third spring 23 is fixedly connected to the support rod 11. The third spring 23 is fixedly connected to the machining box 1. A fixing plate 3 is fixedly connected to each support rod 11. Multiple striking blocks 4 are fixedly connected to one side surface of the fixing plate 3. The surface of each striking block 4 is in contact with the surface of the machining box 1.

[0041] As the cam 12 rotates together with the reciprocating screw 8, it will repeatedly squeeze and disengage from the moving block 13. As the moving block 13 is squeezed and moved downward by the cam 12, the included angle between the two rotating rods 14 increases, and the distance between the two support rods 11 also increases. The third spring 23 deforms. After each fixed plate 3 moves, the striking block 4 will disengage from the surface of the processing box 1. When the moving block 13 moves up to the initial height, the striking block 4 on the fixed plate 3 will re-contact the surface of the processing box 1. During the process of the striking block 4 disengaging from and contacting the surface of the processing box 1, the surface of the processing box 1 can be tapped.

[0042] The lower surface of the processing box 1 has a limiting groove and two discharge ports. Each discharge port is fitted with a sealing plate 2. The support block 10 and the limiting groove are slidably connected. Opening the two sealing plates 2 exposes the two discharge ports to the outside, so that the debris inside the processing box 1 can be discharged and cleaned in a concentrated manner.

[0043] In this invention, during use, the wooden furniture is first placed between two clamping frames 5, with one side surface of the wooden furniture and the surfaces of two positioning plates 17 on one clamping frame 5 in contact. Then, the first hydraulic cylinder 7 drives the other clamping frame 5 to move, reducing the distance between the two clamping frames 5 until the other side surface of the wooden furniture is in contact with the surfaces of the positioning plates 17 on the clamping frame 5. Multiple L-shaped positioning plates 17 are in contact with the two side surfaces of the wooden furniture, which can better fix the wooden furniture. At this time, each grinding roller 22 is in contact with the two side surfaces of the wooden furniture. Then, the second hydraulic cylinder 6 is started and drives the support plate 15 to move upward until the grinding heads 9 connected to the second motor drive end are in contact with the lower surface of the wooden furniture. At this time, each extrusion rod 16 is located between two adjacent arc blocks 20, the surface of the extrusion rod 16 is not in contact with the surface of the two arc blocks 20, and the upper end surface of the extrusion rod 16 is below the upper end surface of the arc block 20. The second hydraulic cylinder 6 stops working.

[0044] Afterwards, the first motor and all the second motors start, and the first electric drive reciprocating screw 8 rotates. During the relative rotation between the reciprocating screw 8 and the processing box 1, the support block 10 moves along the reciprocating screw 8, thereby driving the support plate 15 and each grinding head 9 to move together. Under the drive of the second motor, each grinding head 9 rotates against the surface of the wooden furniture to polish the surface of the wooden furniture. The debris and dust generated during the polishing process will be scattered inside the processing box 1. A protective cover can be attached to the top of the processing box 1 to seal the opening, which is more conducive to preventing debris and dust from flying into the air, effectively preventing environmental pollution, and preventing dust from being inhaled by workers, which is beneficial to the health of workers.

[0045] As each extrusion rod 16 moves along the reciprocating screw 8 with the support plate 15, it abuts against the arc surface of the arc block 20, causing the arc block 20 to move upward, which in turn drives the slide rod 19 and the slider 24 to move upward together. Since the spring constant of the second spring 25 is larger than that of the first spring 28, the first spring 28 undergoes tensile deformation during the upward movement of the slider 24. Initially, the extrusion plate 29 is located below the rotating plate 18. When the tensile deformation of the first spring 28 reaches its maximum, the upper end of the extrusion plate 29 moves upward between the two adjacent rotating plates 18. As the arc block 20 continues to move upward, the slide rod 19 and the slider 24 slide relative to each other, the second spring 25 deforms, and the tilt angle of the hinge rod 27 changes simultaneously, causing the extrusion plate 29 and the slider 24 to slide relative to each other.

[0046] During the relative movement of the extrusion plate 29 and the slider 24, they move together against the surface of a rotating plate 18 without separating from it. During the movement of the rotating plate 18, under the transmission action of the rotating shaft 26, the sanding roller 22 rotates against the side surface of the wooden furniture. When the extrusion rod 16 separates from the surface of the arc block 20, the extrusion plate 29 returns to its initial position. During the process of the extrusion rod 16 moving and extruding each arc block 20 in sequence, the above process is repeated. Each sanding roller 22 will rotate against the side surface of the wooden furniture in sequence, thus enabling a more comprehensive and thorough sanding treatment of the side surface of the wooden furniture. During the sanding treatment of the lower surface of the wooden furniture, the side surface of the wooden furniture can be sanded at the same time, resulting in high sanding efficiency and benefiting the sanding process of wooden furniture.

[0047] In the initial state, the two sides of the airbag 30 are in contact with the upper surface of the bracket 21 and the lower surface of the slider 24, respectively, and the airbag 30 is in a compressed state. When the slider 24 moves up, filters are set at the inlet and outlet of the airbag 30, and air without impurities will enter the airbag 30 through the inlet. When the slider 24 moves down to the initial position again under the elastic force of the first spring 28, it will squeeze and compress the airbag 30 again. The air inside the airbag 30 will be discharged to the surface of the bracket 21 through the downward-sloping outlet, thereby blowing away the dust on the surface of the bracket 21 and preventing dust from accumulating on the surface of the bracket 21 and hindering the movement of the slider 24 and the slide bar 19. This allows the sanding roller 22 to better sand the sides of the wooden furniture.

[0048] As the cam 12 rotates together with the reciprocating screw 8, it will repeatedly squeeze and disengage from the moving block 13. As the moving block 13 is squeezed and moved downward by the cam 12, the included angle between the two rotating rods 14 increases, and the distance between the two support rods 11 also increases. The third spring 23 deforms. After each fixed plate 3 moves, the striking block 4 will disengage from the surface of the processing box 1. When the moving block 13 moves up to the initial height, the striking block 4 on the fixed plate 3 will re-contact the surface of the processing box 1. During the process of the striking block 4 disengaging from and contacting the surface of the processing box 1, the surface of the processing box 1 can be tapped. The vibration of the processing box 1 can accelerate the removal of impurities attached to the inner wall of the processing box 1, avoid a large amount of dust and debris attached to the inner wall of the processing box 1, and facilitate the centralized treatment of dust and debris.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
