Description

Technical Field

[0001] This utility model relates to the field of furniture wood panel processing technology, specifically a double-sided sanding device for wood product processing. Background Technology

[0002] In the processing of wood products, surface sanding is a crucial finishing step. Its quality directly affects the product's appearance, feel, and subsequent coating effect. Especially for components such as boards and strips that require smooth surfaces on both sides, efficient and uniform double-sided sanding is key to improving product quality and production efficiency.

[0003] Currently, the common method for double-sided sanding of wood boards is single-sided sequential sanding. This involves first using sanding equipment to process one side of the wood board, and then having the operator flip the workpiece over to sand the other side. This method is not only inefficient and labor-intensive, but also prone to uneven sanding thickness due to changes in the reference surface during flipping and secondary positioning, which can even result in defective products and make it difficult to ensure consistent product quality.

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] As attached Figure 1 and Figure 2 The double-sided sanding device for wood processing shown includes: a processing table 1, a gantry frame 11 fixedly installed on the top of the processing table 1, a lower mounting frame 12 fixedly installed on the top of the processing table 1, and an upper mounting frame 13 above the lower mounting frame 12; and a double-sided sanding mechanism, which is respectively installed on the lower mounting frame 12 and the upper mounting frame 13, for sanding the wood board on both sides.

[0028] Specifically, when sanding the wood board, the wood board is placed between the lower mounting frame 12 and the upper mounting frame 13. Support rollers are installed on the front and rear sides of the lower mounting frame 12 to support the wood board. Then, the wood board is pushed to move. During the movement, the double-sided sanding mechanism sands both sides of the wood board at the same time, saving the steps of flipping and secondary processing, improving the efficiency of wood board sanding, removing stains from the surface of the wood board, and making the surface of the wood board smoother and flatter.

[0029] As attached Figure 3 , Figure 4 and Figure 7The double-sided grinding mechanism shown includes: a retainer 2, a grinding roller 21, a drive motor 22, a roller a23, a roller b24, a belt 25, and a baffle plate 26. The retainers 2 are fixedly installed on both sides of the top of the lower mounting frame 12 and the upper mounting frame 13. The grinding rollers 21 are rotatably connected between the two opposing retainers 2. The drive motors 22 are fixedly installed on the inner walls of the opposite sides of the lower mounting frame 12 and the upper mounting frame 13. One end of the drive shaft of the two drive motors 22 passes through the lower mounting frame 12 and the upper mounting frame 13 respectively and is fixedly installed with roller a23. The roller b24 is fixedly installed at the end of the rotation shaft of the two grinding rollers 21 near the roller a23. The belt 25 connects the roller a23 and the roller b24. The baffle plate 26 is fixedly installed between the inner walls of the opposite sides of the lower mounting frame 12 and the upper mounting frame 13.

[0030] During sanding, two drive motors 22 are started. After the two drive motors 22 are started, their drive shafts rotate in opposite directions. The drive motors 22 drive the roller a23 to rotate, which in turn drives the roller b24 to rotate via the belt 25. The roller b24 drives the sanding roller 21 to rotate. The retainer 2 supports the sanding roller 21, so that the two sanding rollers 21 rotate in opposite directions, forming a force opposite to that of the feeding wooden board. The wooden board is placed between the two sanding rollers 21, and then the wooden board is pushed to move the two sanding rollers 21 to sand both sides, removing the surface layer of the wooden board, removing dirt, and making both sides smoother.

[0031] In a preferred embodiment, a screw sleeve 3 is fixedly installed on the top of the gantry frame 11, and a screw rod 31 is threadedly connected inside the screw sleeve 3. The bottom end of the screw rod 31 is rotatably connected to the top of the upper mounting frame 13, and a handwheel 32 is fixedly installed on the top end of the screw rod 31.

[0032] Furthermore, manually turning the handwheel 32 drives the screw 31 to rotate, and the screw 31 rotates and engages with the screw sleeve 3, thereby driving the screw 31 to move axially. The screw 31 drives the upper mounting frame 13 to move. By controlling the rotation direction of the handwheel 32, the upper mounting frame 13 can be moved up or down, thereby adjusting the distance between the two grinding rollers 21 in sequence.

[0033] In a preferred embodiment, two guide rods a4 are fixedly connected between the inner top of the gantry frame 11 and the top of the gantry frame 11. Guide cylinders 41 are fixedly connected to the outside of each guide rod a4. Mounting frames 42 are fixedly installed at opposite ends of the upper mounting frame 13. The two guide cylinders 41 are respectively connected to one side of the two mounting frames 42.

[0034] Furthermore, when the upper mounting frame 13 moves, the guide cylinder 41 moves along the outside of the guide rod a4 via the mounting bracket 42, so that the upper mounting frame 13 can only move in the vertical direction, and the movement of the upper mounting frame 13 is more stable, avoiding the upper mounting frame 13 from shaking.

[0035] As attached Figure 5 , Figure 6 and Figure 8 The gantry frame 11 shown has two pairs of guide rods b5 fixedly connected to its opposite sides. The two pairs of guide rods b5 are located on the front and rear sides of the gantry frame 11, respectively. Each guide rod b5 has a slider 51 slidably connected to its outside. Each of the two sliders 51 is rotatably connected to a limit roller 52. Each slider 51 has a through hole 53 that communicates with the internal cavity. Each through hole 53 has a threaded seat 54 fixedly installed at one end. The threaded seat 54 has a bolt 55 threadedly connected inside.

[0036] Specifically: The limiting rollers 52 on both sides can restrict the two sides of the wooden board to prevent it from tilting when pushing the board. The distance between the two limiting rollers 52 can be adjusted. When adjusting, the bolt 55 is unscrewed from the threaded seat 54 a certain distance so that one end of the bolt 55 is separated from the guide rod b5, thereby releasing the restriction on the slider 51. Then, the limiting roller 52 is moved to adjust the position. When the limiting roller 52 moves, it simultaneously drives the top and bottom sliders 51 to move along the outside of the guide rod b5. After adjusting the position, the bolt 55 is screwed into the threaded seat 54 so that one end of the bolt 55 abuts against the guide rod b5, thereby fixing the slider 51 and preventing the limiting roller 52 from moving.

[0037] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
