Description

Technical Field

[0001] This utility model relates to the field of wooden furniture processing technology, specifically a wooden furniture polishing device. Background Technology

[0002] Wooden furniture, also known as solid wood furniture, refers to furniture made from natural wood. Its craftsmanship and design emphasize a rustic, sturdy, and durable style. Surface finishing and protection are relatively simple, such as applying varnish or waxing for protection.

[0003] A search revealed that Chinese patent CN221111178U discloses a wooden furniture sanding device, including a frame. Multiple placement plates are fixed at equal intervals on the inner side of the frame, and two mounting slots are symmetrically arranged on the inner side of the frame. The device utilizes a threaded rod and lead screw that, through threaded engagement, drive the U-shaped mounting plate and moving block to move. The moving block aligns the sanding head with the wooden furniture, while the U-shaped mounting plate moves the sanding mechanism, providing comprehensive sanding of the wooden furniture surface. When the telescopic end of the electric telescopic rod extends, it moves the fixing box, which in turn moves the L-shaped connecting rod fixed to it synchronously. This movement then moves the sliding rod and the rotating wheel. The rotating wheel contacts the wooden furniture surface first, squeezing and fixing the furniture, preventing wobbling during sanding. This solves the problem of incomplete sanding of wooden furniture in existing methods.

[0004] The above-mentioned utility model has the following problems:

[0005] While the aforementioned application can sand the outer surface of wood panels, after a series of processing steps such as cutting and sanding, burrs usually form on the outer walls of the wood. These burrs cannot be effectively removed by the current equipment. Burrs are sharp edges that can easily cause scratches or punctures to operators, handlers, or users, potentially increasing the risk of worker injury. Furthermore, the sanding and deburring process generates a large amount of fine wood chips. These wood chips can easily remain on the workbench or be blown away by wind and mixed in the air. These fine wood chips may affect the cleanliness of the workshop and pose a potential health risk to workers, especially with long-term exposure to high concentrations of wood dust, which may cause respiratory health problems.

[0006] Therefore, those skilled in the art have provided a wooden furniture sanding device to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this invention is to provide a wooden furniture sanding device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A wooden furniture sanding device includes a main body board, a limiting mechanism, and a sanding mechanism. A processing frame board is fixedly connected to the upper surface of the main body board, and a dust collection box is fixedly connected to the bottom end of the main body board. A door is hinged to the outer wall of one end of the dust collection box, and a vacuum cleaner is installed inside the dust collection box. Multiple sets of transmission grooves are opened on the upper surface of the processing frame board. A first threaded rod is rotatably connected to the transmission grooves at both the front and rear ends, and a second threaded rod is rotatably connected to the transmission grooves at both the left and right ends. A sanding mechanism is provided at the upper end of both the first and second threaded rods. A sliding groove is opened on the upper surface of the main body board, and sliders are slidably connected to the left and right ends of the sliding groove. A clamping plate is fixedly connected to the upper end of each slider, and a limiting mechanism is provided at the upper end of each clamping plate.

[0010] As a further embodiment of this utility model: a second bevel gear is fixedly connected to both ends of the first threaded rod, and a first bevel gear is fixedly connected to both ends of the second threaded rod. The first bevel gears are rotatably connected to the adjacent second bevel gears. A servo motor is fixedly connected to the outer wall of the processing frame plate. The power output end of the servo motor passes through the processing frame plate and is fixedly connected to the adjacent first threaded rod. The first bevel gears are all perpendicular to the adjacent second bevel gears, and the first bevel gears mesh with the adjacent second bevel gears.

[0011] As a further embodiment of this utility model: the outer walls of the first threaded rod and the second threaded rod are both threadedly connected to threaded sleeves, and the threaded sleeves are slidably engaged with the corresponding transmission grooves. One end of the threaded sleeve near the main body plate is fixedly connected to an electric telescopic rod, and the other end of the electric telescopic rod is fixedly connected to a drive box. The drive box is equipped with a drive motor, and the power output end of the drive motor passes through the drive box and is fixedly connected to a grinding roller. The grinding roller is fixedly connected to the drive box.

[0012] As a further improvement of this utility model: a connecting box is fixedly connected to the upper end face of each threaded sleeve, and a suction pipe is fixedly connected through and between the connecting box and the dust collection box. A dust collection cover is fixedly connected to the end of the connecting box near the main body plate.

[0013] As a further embodiment of this utility model: an electric turntable is rotatably connected to the center of the main body plate, and a first hinge seat is fixedly connected to both ends of the electric turntable. A second hinge seat is fixedly connected to the end of the slider near the electric turntable, and a hinge rod is hinged between the first hinge seat and the second hinge seat.

[0014] As a further embodiment of this utility model: both the left and right ends of the clamping plate are rotatably connected to a rotating shaft, and the upper end of each rotating shaft is fixedly connected to an L-shaped adjusting frame. Both ends of the L-shaped adjusting frame are fixedly connected to rotating rods, and the upper end of each rotating rod is rotatably connected to an adaptive limiting wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Due to the presence of a limiting mechanism, four sets of L-shaped adjustment frames and adaptive limiting wheels effectively fix the four corners of the wood board, preventing the wood board from shifting or shaking during processing. Since the wood board is firmly fixed in the processing frame and will not shift during the entire processing process, the accuracy and consistency of processing are ensured.

[0017] 2. Equipped with a sanding mechanism, multiple gears are driven by a servo motor to rotate, which in turn drives multiple threaded rods to rotate. This, combined with the sanding rollers, ensures the precision and uniformity of the wood surface processing. The horizontal movement of the threaded sleeves, along with the electric telescopic rod, allows the sanding rollers to accurately engage with the outer wall of the wood, providing a stable and consistent sanding effect. Multiple suction pipes and dust hoods, working in conjunction with the sanding rollers, effectively remove wood chips generated during the sanding process, preventing wood chips from splashing and keeping the processing area clean. The combined use of the dust hoods and sanding rollers effectively reduces wood chips splashing and scattering into the surrounding environment, preventing workers from coming into contact with splashed wood chips or generated dust during operation, thus reducing the risk of accidental injury.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Reference Figure 1-4 This embodiment provides a wooden furniture sanding device, including a dust collection box 1, a main body plate 2, a processing frame plate 3, a transmission groove 4, a first threaded rod 5, a second threaded rod 6, a servo motor 7, a threaded sleeve 8, a connecting box 9, a dust collection hood 10, a dust collection pipe 11, an electric telescopic rod 12, a drive box 13, a sanding roller 14, a first bevel gear 15, a second bevel gear 16, a slide groove 17, a slider 18, a clamping plate 19, an electric turntable 20, a first hinge seat 21, a hinge rod 22, a second hinge seat 23, a rotating shaft 24, an L-shaped adjusting frame 25, a rotating rod 26, and an adaptive limiting wheel 27; the upper end face of the main body plate 2 is fixedly connected to... The processing frame plate 3 has a dust collection box 1 fixedly connected to the bottom of the main body plate 2. The dust collection box 1 has a door hinged to the outer wall of one end. The dust collection box 1 is equipped with a vacuum cleaner. The upper surface of the processing frame plate 3 has multiple sets of transmission grooves 4. The transmission grooves 4 at the front and rear ends are rotatably connected to the first threaded rod 5. The transmission grooves 4 at the left and right ends are rotatably connected to the second threaded rod 6. The upper ends of the first threaded rod 5 and the second threaded rod 6 are all equipped with a grinding mechanism. The upper surface of the main body plate 2 has a sliding groove 17. The left and right ends of the sliding groove 17 are slidably connected to the slider 18. The upper ends of the slider 18 are all fixedly connected to the clamping plate 19. The upper ends of the clamping plate 19 are all equipped with a limit mechanism.

[0026] Example 2

[0027] Reference Figure 1 , 2This embodiment is based on the previous embodiment, but differs in that the first threaded rod 5 is fixedly connected to both ends of a second bevel gear 16, and the second threaded rod 6 is fixedly connected to both ends of a first bevel gear 15. Each first bevel gear 15 is rotatably connected to an adjacent second bevel gear 16. A servo motor 7 is fixedly connected to the outer wall of the processing frame plate 3. The power output end of the servo motor 7 passes through the processing frame plate 3 and is fixedly connected to an adjacent first threaded rod 5. Each first bevel gear 15 is perpendicular to an adjacent second bevel gear 16, and the first bevel gear 15 meshes with the adjacent second bevel gear 16. The first threaded rod 5 and the second bevel gear 16... The outer wall of each threaded rod 6 is threaded with a threaded sleeve 8, and each threaded sleeve 8 is slidably engaged with the corresponding transmission groove 4. Each threaded sleeve 8 is fixedly connected to an electric telescopic rod 12 at one end near the main body plate 2. Each electric telescopic rod 12 is fixedly connected to a drive box 13 at the other end. Each drive box 13 is equipped with a drive motor. Each drive motor power output end passes through the drive box 13 and is fixedly connected to a grinding roller 14. Each grinding roller 14 is fixedly connected to the drive box 13. Each threaded sleeve 8 is fixedly connected to a connecting box 9 at the upper end. Each connecting box 9 and the dust collection box 1 are connected through and fixedly connected to a dust collection pipe 11. Each connecting box 9 is fixedly connected to a dust collection cover 10 at one end near the main body plate 2.

[0028] Place the wood board in the processing frame 3, start the electric turntable 20, the electric turntable 20 drives the first hinge seat 21 connected at the left and right ends to rotate in a circle. The first hinge seat 21 moves synchronously through the hinge rod 22 at the upper end and pulls the second hinge seat 23 to move. The slider 18 at the upper end of the second hinge seat 23 is limited by the slide groove 17 and can only move within the slide groove 17, thereby driving the two sets of clamping plates 19 to move simultaneously to one end of the wood board.

[0029] When the two sets of adaptive limiting wheels 27 at the upper end of the L-shaped adjustment frames 25 at both ends of the clamping plate 19 come into contact with the side wall of the wood board, they will drive the other set of adaptive limiting wheels 27 to abut against the side wall of the wood board according to the rotation of the rotating shaft 24, so that the adaptive limiting wheels 27 at the upper end of one set of L-shaped adjustment frames 25 fix one corner of the wood board. Through the four sets of L-shaped adjustment frames 25, all four corners of the wood board are fixed.

[0030] It should be added that the dimensions of the wood boards in the same batch are all uniform, and the limiting mechanism only provides a limit to the wood boards to prevent them from shaking during processing.

[0031] It should be added that multiple sets of adaptive limit wheels 27 all abut against the corners of the wood board, which can better prevent the wood board from shifting. In addition, the contact area between the adaptive limit wheels 27 and the wood board is small, so it will not affect the subsequent sanding work of the wood board.

[0032] Example 3

[0033] Reference Figure 1 , 3 4. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that an electric turntable 20 is rotatably connected to the center of the main body plate 2. The electric turntable 20 is fixedly connected to the left and right ends of the electric turntable 20 with first hinge seats 21. The slider 18 is fixedly connected to the end of the electric turntable 20 with a second hinge seat 23. A hinge rod 22 is hinged between the first hinge seat 21 and the second hinge seat 23. The clamping plate 19 is rotatably connected to the left and right ends with rotating shafts 24. An L-shaped adjusting frame 25 is fixedly connected to the upper end of the rotating shaft 24. A rotating rod 26 is fixedly connected to both ends of the L-shaped adjusting frame 25. An adaptive limit wheel 27 is rotatably connected to the upper end of the rotating rod 26.

[0034] The servo motor 7 is started, which drives the first threaded rod 5 to rotate. The first threaded rod 5 drives the second bevel gear 16 on the outer wall to rotate. The second bevel gear 16 drives the meshing first bevel gear 15 to rotate. The first bevel gear 15 drives the two sets of second threaded rods 6 to rotate. The second threaded rod 6 drives the other set of second bevel gears 16 to rotate through the first bevel gear 15 at the other end. The second bevel gear 16 drives the other set of first threaded rods 5 to rotate. Thus, the two sets of first threaded rods 5 and the two sets of second threaded rods 6 rotate, causing the corresponding threaded sleeve 8 to move horizontally in the transmission groove 4 of the processing frame plate 3.

[0035] The horizontal movement of the threaded sleeve 8 drives the electric telescopic rod 12, the drive box 13, and the grinding roller 14 to move horizontally in sync. Through the telescopic nature of the electric telescopic rod 12, the grinding roller 14 comes into contact with the outer wall of the wood board. The drive motor in the drive box 13 is started, which can grind and deburr the outer wall of the wood board. In conjunction with the horizontal movement of the threaded sleeve 8, the wood board can be processed evenly.

[0036] During the sanding process, the vacuum cleaner in the dust collection box 1 is started. The vacuum cleaner continuously sucks air through multiple sets of suction pipes 11 on the outer wall. The suction pipes 11 suck up the wood chips generated during the sanding process through the connecting box 9 and the dust collection hood 10, thereby ensuring the cleanliness of the processing area.

[0037] It should be added that, since each set of dust hoods 10 and sanding rollers 14 are set on the same threaded sleeve 8, the dust hoods 10 and sanding rollers 14 can be used together to prevent wood chips from flying.

[0038] It should be added that the inner walls of the suction pipe 11, the connecting box 9, and the suction hood 10 are connected.

[0039] It should be added that the operator can control the rotation of the servo motor 7 to adjust the direction of movement of the threaded sleeve 8;

[0040] It should be added that staff can open the top door of the vacuum cleaner 1 to clean the inside of the vacuum cleaner 1.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
