Description

Technical Field

[0001] This invention belongs to the field of furniture board technology, and in particular relates to a device and method for simultaneous sanding of two sides of furniture boards. Background Technology

[0002] After furniture boards are processed and shaped, their surfaces often have inherent defects and processing residues. Sanding is a core process to ensure the quality of the finished product and the user experience. Its main functions are as follows: First, it eliminates surface defects and smooths the base. Natural wood itself has knots, burrs, and unevenness, while artificial boards such as particleboard and MDF may have demolding residue, glue marks, and curled edges. Cutting and processing can also produce chipped edges and saw marks. Sanding can quickly remove these flaws, making the overall surface of the board smooth and flat, laying a good foundation for subsequent painting and veneer processes, and preventing flaws from showing through the finish and affecting the appearance of the finished product. Second, it improves the adhesion of the finish and extends its service life. Whether painting, applying wood veneer, or applying decorative film, the surface of the board needs to have a suitable roughness. An overly smooth surface makes it difficult for paint and adhesive molecules to adhere, which can easily lead to problems such as paint peeling, glue separation, and veneer peeling. Appropriately sanded surfaces increase the contact area, allowing the finish material to bond more tightly to the board itself, greatly improving the structural stability and service life of the furniture. Third, it optimizes the appearance and texture and enhances aesthetics. Sanding makes the wood grain clearer and more natural, and also makes the edges of the board smoother, avoiding sharp burrs from scratching users. At the same time, it eliminates uneven color differences on the surface of the board, making subsequent coloring more even and transparent. The tactile and visual texture of the finished product will be significantly improved, meeting consumers' demand for high-quality furniture.

[0003] In the actual production process of furniture board sanding, most existing board sanding equipment only has the ability to sand one side, and cannot complete the sanding of both sides of the board at one time. After one side of the board is sanded, the worker needs to manually stop the machine, remove the board from the equipment, flip it over and fix it, and then sand the other side. This process not only slows down the processing efficiency, but also increases the workload of the workers. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a device for simultaneous sanding of two sides of furniture panels, comprising: A base, on which two first support frames arranged symmetrically in the horizontal direction are fixedly connected; Two second support frames are arranged symmetrically in the horizontal direction. The second support frames are fixedly connected to the base, and the first support frame is located on both sides of the second support frame. A double-sided sanding assembly, which is mounted on the first support frame, is used to perform double-sided sanding operations on furniture boards. An auxiliary component is mounted on the second support frame.

[0005] As a preferred embodiment of the present invention, the double-sided polishing assembly includes: A load-bearing rotating frame is rotatably connected to the top of the first support frame. One end of the load-bearing rotating frame is equipped with a first tension spring, and the other end of the first tension spring is installed on the first support frame.

[0006] As a preferred embodiment of the present invention, the bottom of each of the first support frames is rotatably connected to a first rotating shaft; The top of each of the first support frames is rotatably connected to a second pivot. A third rotating shaft is rotatably connected to the bearing rotating frame. Drive wheels are fixedly connected to the first rotating shaft, the second rotating shaft, and the third rotating shaft. A sanding belt for sanding the plate is sleeved on the three drive wheels, and two sanding belts are arranged opposite to each other.

[0007] As a preferred embodiment of the present invention, a drive motor is mounted on the upper side of the base; One of the first rotating shafts and the output end of the drive motor are each equipped with a first synchronous pulley, and a first synchronous belt is fitted onto the first synchronous pulley; A second synchronous pulley is installed between the two first rotating shafts, and a second synchronous belt is fitted onto the second synchronous pulley.

[0008] As a preferred embodiment of the present invention, the base is provided with two symmetrically arranged dust suction pipes, which are located on both sides of the sanding belt.

[0009] As a preferred embodiment of the present invention, the auxiliary component includes: A slide rail is fixedly connected to two second support frames, and two first sliders are slidably connected on the slide rail. A limit frame is fixedly connected to the upper side of the first slider. The limiting frame is slidably connected to a first connecting rod; A second tension spring is fixedly connected to the bottom of the first connecting rod, and the other end of the second tension spring is fixedly connected to the limiting frame; The top end of the first connecting rod is fixedly connected to a limiting fixing plate that can contact the top of the plate.

[0010] As a preferred embodiment of the present invention, four symmetrically arranged arc-shaped support frames are fixedly connected to the bottom of the slide rail; The arc-shaped support frame is located on both sides of the slide rail; Two telescopic rods are fixedly connected to the arc-shaped support frame, arranged symmetrically at the top and bottom. The extended end of each telescopic rod is fixedly connected to a fixing ring, and a spring is installed between the fixing ring and the fixed end of the telescopic rod.

[0011] In a preferred embodiment of the present invention, a hollow rotating rod is rotatably connected between the fixed rings; A sponge roller is fixedly connected to the outer surface of the hollow rotating rod; A drive motor is installed at the bottom of the arc-shaped support frame. One end of the cavity rotating rod is fixedly connected to the output end of the drive motor. A rotary joint is installed at the top of the cavity rotating rod, and a flexible hose is installed on the rotary joint.

[0012] A method for simultaneously sanding both sides of furniture panels, using any one of the aforementioned simultaneous sanding devices for furniture panels, comprising: Step S1: The staff first moves the device to the designated polishing area; Step S2: Place the plate to be sanded vertically onto the auxiliary component of the second support frame, and the auxiliary component will fix the plate.

Step S5: After sanding, the staff removes the board from the auxiliary components.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the field of furniture board technology, this invention addresses the issue that existing furniture board sanding processes often involve equipment that only sands one side, failing to complete sanding on both sides of the board in a single operation. After one side is sanded, workers must manually stop the machine, remove the board from the equipment, flip it over, and then sand the other side. This process not only slows down processing efficiency but also increases the workload for workers. The double-sided sanding component solves these problems, resulting in the following benefits: This invention, through the design of a double-sided grinding component, can grind both sides of a board simultaneously in a single process, eliminating the need for flipping and secondary grinding. This shortens the grinding process, reduces processing time, avoids warping and deformation caused by single-sided grinding, and improves the uniformity of grinding on both sides of the board.

[0014] This invention, through the addition of auxiliary components, can stably clamp and fix vertically placed plates, automatically feeding the plates to the sanding area without the need for manual hand-pushing of the plates. This avoids sanding deviations caused by manual plate support and simplifies the plate loading and unloading operation. Attached Figure Description

[0017] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Please see Figures 1 to 6 This invention provides a simultaneous two-sided sanding processing device for furniture boards, comprising: a base 1, with two horizontally symmetrically arranged first support frames 2 fixedly connected above the base 1; two horizontally symmetrically arranged second support frames 3, the second support frames 3 being fixedly connected to the base 1, with the first support frames 2 located on both sides of the second support frames 3; a double-sided sanding assembly, the sanding assembly being installed on the first support frames 2 for performing double-sided sanding operations on the furniture boards; and an auxiliary assembly, the auxiliary assembly being installed on the second support frames 3.

[0020] The above solution involves the following steps: When performing double-sided sanding on furniture boards, the operator first moves the device to the designated sanding area, then places the board to be sanded vertically onto the auxiliary component of the second support frame 3. The auxiliary component secures the board, and then moves it towards the double-sided sanding component. Once in the double-sided sanding area, the double-sided sanding component performs double-sided sanding on the board. After sanding, the operator removes the board from the auxiliary component. The double-sided sanding is then completed directly through the double-sided sanding component, solving the problem that existing methods can only sand one side of the board at a time and reducing the number of sanding steps.

[0021] Furthermore, the double-sided polishing assembly includes: a bearing rotating frame 4 rotatably connected to the top of the first support frame 2, one end of the bearing rotating frame 4 is equipped with a first tension spring 5, and the other end of the first tension spring 5 is installed on the first support frame 2.

[0022] Furthermore, the bottom of the first support frame 2 is rotatably connected to a first rotating shaft 6; the top of the first support frame 2 is rotatably connected to a second rotating shaft 7; the bearing rotating frame 4 is rotatably connected to a third rotating shaft 8; drive wheels 9 are fixedly connected to the first rotating shaft 6, the second rotating shaft 7 and the third rotating shaft 8; abrasive belts 10 for grinding the plate are sleeved on the three drive wheels 9; and two abrasive belts 10 are arranged opposite to each other.

[0023] Furthermore, a drive motor 11 is installed on the upper side of the base 1; a first synchronous pulley 12 is installed on one of the first rotating shafts 6 and the output end of the drive motor 11, and a first synchronous belt 13 is sleeved on the first synchronous pulley 12; a second synchronous pulley 14 is installed between the two first rotating shafts 6, and a second synchronous belt 15 is sleeved on the second synchronous pulley 14.

[0024] Furthermore, the base 1 is provided with two symmetrically arranged dust suction pipes 16, which are located on both sides of the sanding belt 10.

[0025] Using the above scheme: In use, the worker places the sanding belt 10 onto the three drive wheels 9. Under the action of the first tension spring 5, the bearing rotating frame 4 rotates on the first support frame 2, causing the third rotating shaft 8 and drive wheels 9 to rotate upwards. The tension of the sanding belt 10 is adjusted. After the board moves to the sanding area, the output end of the drive motor 11 drives the first synchronous wheel 12 to rotate. Through the first synchronous belt 13, it drives another first synchronous wheel 12 and the corresponding first rotating shaft 6 to rotate. When the first rotating shaft 6 rotates, it drives its own second synchronous wheel 14. The second synchronous wheel 14 is driven by the second synchronous belt 15. The first shaft 6 on the other first support frame 2 and the drive wheel 9 on the shaft rotate synchronously. Under the rotation of the two first shafts 6, and with the cooperation of the drive wheels 9 on the second shaft 7 and the third shaft 8, the two sanding belts 10 rotate. The two sides of the board come into contact with the sanding belts 10, and the sanding belts 10 work on the surface of the board to achieve simultaneous sanding of both sides of the board. During the sanding process, the dust suction pipe 16 sucks up the dust generated by sanding to complete the dust removal operation. The two sides of the board can be sanded simultaneously without changing the sanding surface multiple times, which improves the efficiency of board sanding.

[0026] It should be noted that the dust removal fan can be connected to the two suction pipes 16 via an external hose. The dust can be drawn into the suction pipes 16 by the action of the dust removal fan for dust removal.

[0027] Furthermore, the auxiliary component includes: a slide rail 17 fixedly connected to two second support frames 3, two first sliders 18 slidably connected to the slide rail 17, a limit frame 31 fixedly connected to the upper side of the first sliders 18; a first connecting rod 19 slidably connected inside the limit frame 31; a second tension spring 20 fixedly connected to the bottom of the first connecting rod 19, the other end of the second tension spring 20 fixedly connected to the limit frame 31; and a limit fixing plate 21 that can contact the top of the plate fixedly connected to the top of the first connecting rod 19.

[0028] Furthermore, four symmetrically arranged arc-shaped support frames 22 are fixedly connected to the bottom of the slide rail 17; the arc-shaped support frames 22 are located on both sides of the slide rail 17; two vertically symmetrically arranged telescopic rods 23 are fixedly connected to the arc-shaped support frames 22, and a fixing ring 24 is fixedly connected to the extended end of the telescopic rod 23, and a spring 25 is installed between the fixing ring 24 and the fixed end of the telescopic rod 23.

[0029] Furthermore, a hollow rotating rod 26 is rotatably connected between the fixed rings 24; a sponge roller 27 is fixedly connected to the outer surface of the hollow rotating rod 26; a drive motor 28 is installed at the bottom of the arc-shaped support frame 22; one end of the hollow rotating rod 26 is fixedly connected to the output end of the drive motor 28; a rotary joint 29 is installed at the top of the hollow rotating rod 26; and a flexible hose 30 is installed on the rotary joint 29.

[0030] Using the above scheme: In use, adjust the distance between the two first sliders 18 on the slide rail 17 according to the length of the plate. Place the plate on the upper surface of the first sliders 18 so that the left and right sides of the plate are in contact with the limiting frame 31. Under the action of the second tension spring 20, the first connecting rod 19 pulls the top limiting fixing plate 21 to fit against the top of the plate, completing the installation and fixing of the plate. The first sliders 18 drive the plate to move from right to left. After the plate moves to the preset position, it enters the first set of two oppositely arranged sponge rollers 27. Under the action of the spring 25, the extension end of the telescopic rod 23 extends, pushing the fixing ring 24 to make the plate... The cotton roller 27 adheres to the board, and the liquid in the flexible hose 30 enters the cavity rotating rod 26, then flows into the sponge roller 27 to wet the sponge roller 27 and wipe the surface of the board, reducing the accumulation of sanding dust and the phenomenon of board fuzzing during the sanding process. The output end of the drive motor 28 rotates, driving the cavity rotating rod 26 to rotate, and the sponge roller 27 rotates synchronously. With the cooperation of the four sponge rollers 27, the board is pushed to move towards the sanding area. The board enters the sanding area to complete the sanding. After sanding, the board enters the second set of sponge rollers 27 on the left. The second set of sponge rollers 27 applies different liquids to the surface of the board to complete the dust removal process.

[0031] It should be noted that: First, the first application of liquid is a wet dust-suppressing liquid, and the second application of liquid is an anti-static liquid to eliminate static dust generated during grinding. Therefore, two pumps can be used, with the other end of the flexible hose 30 connected to the pump output for liquid delivery. Second, since the flexible hose 30 is connected to the cavity rotating rod 26 via the rotary joint 29, the flexible hose 30 will not rotate with the cavity rotating rod 26. Third, after the plate is installed, the fixing screws on the limiting fixing plate 21 can be screwed into the top of the plate for fixation.

[0032] A method for simultaneously sanding both sides of furniture panels, using any one of the aforementioned simultaneous sanding devices for furniture panels, comprising: Step S1: The staff first moves the device to the designated polishing area; Step S2: Place the plate to be sanded vertically onto the auxiliary component of the second support frame, and the auxiliary component will fix the plate. Step S3: The auxiliary component moves the board towards the double-sided grinding component; Step S4: After the board is moved to the double-sided sanding area, the double-sided sanding component performs double-sided sanding on the board. Step S5: After sanding, the staff removes the board from the auxiliary components.

[0033] Working principle of the invention: When performing double-sided sanding on furniture boards, the worker first moves the device to the designated sanding area. The worker then places the sanding belt 10 onto the three drive wheels 9. Under the action of the first tension spring 5, the bearing rotating frame 4 rotates on the first support frame 2, causing the third rotating shaft 8 and drive wheels 9 to rotate upwards. The tension of the sanding belt 10 is adjusted, and the distance between the two first sliders 18 on the slide rail 17 is adjusted according to the board length. The board is placed on the upper surface of the first sliders 18, ensuring that both sides of the board are in contact with the limiting frame 31. Under the action of the second tension spring 20, the first connecting rod 19 pulls the top... The limiting and fixing plate 21 is attached to the top of the plate to complete the installation and fixing of the plate. The first slider 18 drives the plate to move from right to left. After the plate moves to the preset position, it enters the first set of two oppositely arranged sponge rollers 27. Under the action of the spring 25, the extension end of the telescopic rod 23 extends, pushing the fixing ring 24 to make the sponge roller 27 fit the plate. The liquid in the flexible hose 30 enters the cavity rotating rod 26 and then flows into the sponge roller 27 to wet the sponge roller 27 and wipe the surface of the plate, so as to reduce the accumulation of sanding belt powder and the phenomenon of plate fuzzing during the sanding process. The output end of the drive motor 28 rotates to drive the cavity rotating rod 26. As the four sponge rollers 27 rotate, they rotate synchronously, pushing the board towards the grinding area. After the board moves to the grinding area, the output of the drive motor 11 drives the first synchronous wheel 12 to rotate. This, in turn, drives another first synchronous wheel 12 and the corresponding first rotating shaft 6 to rotate via the first synchronous belt 13. When the first rotating shaft 6 rotates, it drives its own second synchronous wheel 14. The second synchronous wheel 14, via the second synchronous belt 15, drives the first rotating shaft 6 on another first support frame 2 and the drive wheel 9 on that shaft to rotate synchronously. Under the rotation of the two first rotating shafts 6, and the second... With the cooperation of the drive wheel 9 on the rotating shaft 7 and the third rotating shaft 8, the two sanding belts 10 rotate, and the two sides of the board come into contact with the sanding belts 10. The sanding belts 10 work on the surface of the board to achieve simultaneous sanding of both sides of the board. During the sanding process, the dust suction pipe 16 sucks up the dust generated by sanding to complete the dust removal operation. The two sides of the board can be sanded simultaneously without changing the sanding surface multiple times, which improves the efficiency of the board sanding operation. After sanding, the board enters the second set of sponge rollers 27 on the left. The second set of sponge rollers 27 applies different liquids to the surface of the board to complete the dust removal process.
