Description

Technical Field

[0001] This utility model relates to the technical field of furniture surface polishing equipment, specifically a furniture surface roughening treatment device. Background Technology

[0002] In furniture manufacturing, surface roughening is a crucial step. However, current surface roughening devices have several drawbacks. Firstly, traditional clamping and positioning structures are poorly adaptable to workpieces of different sizes and shapes, lacking stability and prone to displacement during grinding, thus affecting accuracy and finish. Secondly, the grinding mechanism's position adjustment is inflexible, typically allowing only unidirectional movement, and its installation and maintenance are inconvenient, failing to meet the demands for efficient and precise grinding. Therefore, we propose a new surface roughening device for furniture. Utility Model Content

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.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a furniture surface roughening treatment device, including a base 1, a side plate 11 on the base 1, a first cylinder 13 on the side of the side plate 11, a positioning seat 12 connected to the side of the first cylinder 13, a clamping mechanism symmetrically arranged in the top inner cavity of the positioning seat 12, the clamping mechanism including a "U"-shaped limiting frame 14, a detachable lifting seat 18 above the positioning seat 12, a snap-fit ​​plate 19 at the bottom of the lifting seat 18, a sliding groove 21 at the bottom of the lifting seat 18, a slider 22 inside the sliding groove 21, a third cylinder 23 connected to one end of the slider 22, a mounting seat 24 at the bottom of the slider 22, the bottom of the mounting seat 24 connected to a mounting frame 26 by a pull rod 25, a connecting seat 27 detachably installed in the lower opening of the mounting frame 26 by screws 28, and a grinding mechanism installed below the connecting seat 27. Specifically, lever 25 is an electric lever that can achieve a vertical drive effect.

[0018] The workpiece can be positioned by the clamping mechanism. The first cylinder 13 can move the positioning seat 12 left and right. The third cylinder 23 drives the slider 22 to move in the slide groove 21, thereby realizing the forward and backward movement of the grinding mechanism. At the same time, the pull rod can drive the grinding mechanism to move up and down, so that the grinding mechanism can move in multiple directions, which is convenient for roughing the surface of furniture.

[0019] In the above scheme, a second cylinder 17 is provided on the outer side of the limiting frame 14, and an adjusting screw 16 is screwed onto the side wall of the limiting frame 14. A clamping block 15 is movably connected to the end of the adjusting screw 16. The second cylinder 17 can drive the limiting frame 14 to move, and the adjusting screw 16 can drive the clamping block 15 to move, thereby realizing the clamping and fixing of workpieces of different sizes, improving the applicability of the device. At the same time, the movably connected clamping block can be adaptively adjusted according to the shape of the workpiece to ensure clamping stability.

[0020] In the above scheme, the bottom end of the snap-fit ​​plate 19 snaps into the movable groove opened at the top of the side plate 11, and the side of the side plate 11 is screwed with a limit bolt 2. The cooperation between the snap-fit ​​plate and the movable groove enables the installation of the lifting seat on the side plate, and the limit bolt can fix the position of the lifting seat, making the lifting seat 18 detachable, which facilitates the installation, debugging and maintenance of the device, and the height position of the lifting seat can be adjusted according to actual needs.

[0021] In the above solution, the sanding mechanism includes at least two sets of sanding wheels 3. The sanding wheels 3 are installed in the grooves 29 at the bottom of the connecting seat 27, and the sanding wheels 3 are connected to the drive motor 32 via a rotating shaft 31. The drive motor 32 drives the sanding wheels 3 to rotate via the rotating shaft 31. At least two sets of sanding wheels can simultaneously sand the furniture surface, improving sanding efficiency. The sanding wheels are installed in the grooves, resulting in a compact structure. Furthermore, the connection via the rotating shaft ensures stable power transmission and guarantees the sanding effect.

[0022] In the above scheme, a control switch is provided on the base 1. The control switch is used to control the operation of various components such as cylinders and drive motors in the device. Operators can conveniently start and stop the device and adjust the working status of each component through the control switch, which improves the ease of operation and human-machine interaction of the device.

[0023] In the above solution, a protective plate is provided on the inner side of the clamping block 15. The protective plate can reduce the direct hard contact between the clamping block and the workpiece surface when the clamping block clamps the workpiece, prevent scratches, indentations and other damage to the workpiece surface, and protect the workpiece surface from damage during the clamping process.

[0024] Working principle:

[0025] This furniture surface roughening device first places the furniture workpiece to be roughened in the clamping mechanism at the top of the positioning seat 12. The second cylinder 17 drives the limiting frame 14 to move, positioning the workpiece between the two clamping mechanisms. Then, the adjusting screw 16 is rotated, causing the clamping block 15 to move until the protective plate inside the clamping block 15 contacts and clamps the workpiece, achieving stable positioning. Next, according to the location of the furniture surface requiring roughening, the first cylinder 13 is activated via a control switch. The first cylinder 13 pushes the positioning seat 12 to move left and right on the side of the side plate 11, adjusting the left and right position of the workpiece. Simultaneously, the lifting seat 18 is engaged in the movable groove at the top of the side plate 11 via the snap-fit ​​plate 19. The height of the lifting seat 18 can be adjusted by loosening the limiting bolt 2 as needed, and then tightened after adjustment to fix it, thus determining the height position of the grinding mechanism. Then, the third cylinder 23 is activated, which drives the slider 22 to move back and forth in the groove 21 at the bottom of the lifting seat 18. The slider 22 drives the mounting bracket 26, connecting seat 27 and grinding mechanism to move back and forth through the mounting base 24 and the pull rod 25. At the same time, the drive motor 32 drives the grinding wheel 3 to rotate through the rotating shaft 31 to roughen the surface of the furniture.
