Description

Technical Field

[0001] This utility model relates to the technical field of triangular sanding edge machine, specifically to a device for the vertical movement of the structure of a triangular sanding edge machine. Background Technology

[0002] In the wood processing industry, triangular edge sanders are key equipment for achieving fine grinding of wood edges. Their core function lies in using the cyclical motion of a sanding belt to polish the wood edges, achieving a smooth and flat finish. However, traditional triangular edge sanders often face numerous technical challenges in practical applications, making it difficult to meet the demands for efficient and precise processing.

[0003] The existing sanding belt movement and tension adjustment mechanisms of sanding machines have some shortcomings. When the movement structure of most equipment drives the sanding belt to move up and down, the tension of the sanding belt changes greatly during the movement. Traditional tension adjustment methods are mostly rigid and cannot adapt to the tension changes. This can easily cause the sanding belt to be loose or too tight. Loose sanding belt will result in insufficient grinding force, affecting the processing effect. Excessive tightness will increase the friction between the sanding belt and the parts, and may even lead to the sanding belt breakage, increasing the risk of production interruption and equipment maintenance costs.

The compression spring will push the support frame through elastic action, so that the first pulley always exerts an outward force.

[0010] Preferably, the drive structure includes a mounting plate, a support plate symmetrically fixedly connected to the outer wall of the bottom of the mounting plate, a support column fixedly connected to the outer wall of the support plate, a bearing fixedly connected to the outer wall of the support column, a support roller fixedly connected to the outer wall of the bearing, a sliding groove formed on the outer wall of the mounting plate, a rotating shaft rotatably connected to the inner wall of the mounting plate, a rotating roller fixedly connected to the outer wall of the rotating shaft, a motor rotatably connected to the outer wall of the rotating shaft on the side away from the rotating roller, and anti-slip pads fixedly connected to the outer walls of the rotating roller and the support roller.

[0011] Preferably, the outer wall of the motor is fixedly connected to the outer wall of the mounting plate, and the rotating roller is positioned above the support roller, forming a triangular shape.

[0012] Preferably, the outer wall of the hydraulic rod is fixedly connected to the outer wall of the mounting plate, and the outer wall of the slider is slidably connected to the inner wall of the slide groove.

[0014] (III) Beneficial Effects

[0015] This utility model provides a vertical movement device for the structure of a triangular sander edge sander. It has the following beneficial effects:

[0016] (i) The axial movement structure drives the support block and support frame to move through the hydraulic rod. The support block is slidably connected to the slide groove of the mounting plate through the slider, so that it moves stably along the slide groove. The second pulley provides tension to support the sanding belt upward. When the sanding belt changes tension due to axial movement, the compression spring will adjust the position of the slide rod by extension and retraction, so that the first pulley is always in close contact with the inner wall of the sanding belt. This adaptive adjustment mechanism can effectively avoid the sanding belt from becoming loose or overly tight, ensuring that the sanding belt is always in stable contact with the relevant components during the axial movement, thus ensuring the uniformity of the grinding effect.

[0017] (ii) This drive structure uses the anti-slip pads on the outer walls of the rotating roller and the support roller to contact the inner wall of the sanding belt. The rotational force is transmitted by friction, which makes the sanding belt circulate along the outer walls of the support roller and the rotating roller, providing continuous and strong power for grinding operations. At the same time, the support roller is connected to the support column through the bearing and can rotate freely with the movement of the sanding belt, which greatly reduces the frictional resistance during the movement, makes the sanding belt run more smoothly, and improves the grinding efficiency.

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] Please see Figure 1-4This utility model provides a technical solution: a triangular sander edge sander structure with a vertical movement device, comprising: a drive structure 1, a moving structure 2 fixedly connected to the outer wall of the drive structure 1, and a sanding belt 3 slidably connected to the outer wall of the drive structure 1; the moving structure 2 includes a hydraulic rod 21, a support block 22 fixedly connected to the outer wall of the hydraulic rod 21, a sliding rod 23 symmetrically slidably connected to the inner wall of the support block 22, a compression spring 24 fixedly connected to the outer wall of the sliding rod 23, a support frame 25 fixedly connected to the outer wall of the sliding rod 23 away from the compression spring 24, a first pulley 26 rotatably connected to the inner wall of the support frame 25, a support rod 27 symmetrically fixedly connected to the outer wall of the support block 22, a second pulley 28 rotatably connected to the inner wall of the support rod 27 away from the support block 22, and a slider 29 fixedly connected to the outer wall of the support block 22.

[0025] The outer wall of the compression spring 24 away from the slide rod 23 is fixedly connected to the inner wall of the support block 22. The outer wall of the support block 22 is fixedly connected to the outer wall of the telescopic rod on the hydraulic rod 21. The two ends of the compression spring 24 are connected to the slide rod 23 and the support block 22 respectively. The compression spring 24 will push the support frame 25 through elastic action, so that the first pulley 26 always exerts an outward force.

[0026] The drive structure 1 includes a mounting plate 11. A support plate 12 is symmetrically fixedly connected to the outer wall of the bottom of the mounting plate 11. A support column 13 is fixedly connected to the outer wall of the support plate 12. A bearing 14 is fixedly connected to the outer wall of the support column 13. A support roller 15 is fixedly connected to the outer wall of the bearing 14. A groove 17 is opened on the outer wall of the mounting plate 11. A rotating shaft 18 is rotatably connected to the inner wall of the mounting plate 11. A rotating roller 19 is fixedly connected to the outer wall of the rotating shaft 18. A motor 191 is rotatably connected to the outer wall of the rotating shaft 18 on the side away from the rotating roller 19. Anti-slip pads 16 are fixedly connected to the outer walls of the rotating roller 19 and the support roller 15.

[0027] The outer wall of the motor 191 is fixedly connected to the outer wall of the mounting plate 11, and the rotating roller 19 is positioned above the support roller 15, forming a triangular shape.

[0028] The outer wall of the hydraulic rod 21 is fixedly connected to the outer wall of the mounting plate 11, and the outer wall of the slider 29 is slidably connected to the inner wall of the slide groove 17. The hydraulic rod 21 is fixed on the mounting plate 11. When its telescopic rod extends or retracts, it will drive the fixedly connected support block 22 and support frame 25 to move synchronously. The support block 22 is slidably connected to the slide groove 17 of the mounting plate 11 through the slider 29, ensuring that the support block 22 can only move stably in the direction of the slide groove 17.

[0029] The inner wall of the sanding belt 3 is slidably connected to the outer wall of the first pulley 26, the second pulley 28 and the anti-slip pad 16. The sanding belt 3 is sleeved on the outside of the support roller 15 and the rotating roller 19. In the initial state, the second pulley 28 is in contact with the inner wall of the sanding belt 3. The second pulley 28 supports the sanding belt 3 upward through the support rod 27, which plays a tension role.

[0030] When in use, the mounting plate 11 on the drive structure 1 is installed on the wood processing equipment. The drive structure 1 is the power core of the whole device, responsible for driving the sanding belt 3 to run continuously. At the same time, the traversing structure 2 drives the sanding belt 3 to move up and down and exert tension during operation.

[0031] When the motor 191 starts, its output shaft drives the rotating shaft 18 to rotate, which in turn causes the rotating roller 19 fixed on the outer wall of the rotating shaft 18 to rotate synchronously. The rotating roller 19 and the support roller 15 below contact the inner wall of the sanding belt 3 through the anti-slip pad 16 on the outer wall. The rotational force of the rotating roller 19 is transmitted to the sanding belt 3 by friction, so that the sanding belt 3 circulates along the outer wall of the support roller 15 and the rotating roller 19, realizing the grinding power output of the sanding belt. The support roller 15 is connected to the support column 13 on the support plate 12 through the bearing 14, and can rotate freely with the movement of the sanding belt 3 to reduce friction. The anti-slip pad 16 can enhance the friction between the rotating roller 19, the support roller 15 and the sanding belt 3, prevent slippage and ensure transmission stability.

[0032] The hydraulic rod 21 is fixed on the mounting plate 11. When its telescopic rod extends or retracts, it will drive the fixedly connected support block 22 and support frame 25 to move synchronously. The support block 22 is slidably connected to the slide groove 17 of the mounting plate 11 through the slider 29, ensuring that the support block 22 can only move stably along the direction of the slide groove 17 and avoid deviation.

[0033] In the initial state, the second pulley 28 is in contact with the inner wall of the sanding belt 3. The second pulley 28 supports the sanding belt 3 upward through the support rod 27, which provides tension. When the support block 22 moves downward, the first pulley 26 and the second pulley 28 on the support block 22 will move downward synchronously, so that the first pulley 26 contacts the inner wall of the sanding belt 3. As the support block 22 moves up and down, the first pulley 26 and the second pulley 28 will move up and down synchronously, thereby pushing the sanding belt 3 to move vertically. The sliding rod 23 slides inside the support block 22, and the two ends of the compression spring 24 sleeved on its outer wall are connected to the sliding rod 23 and the support block 22 respectively. When the sanding belt 3 changes tension due to the movement, the compression spring 24 will adjust the position of the sliding rod 23 by extension and retraction, so that the first pulley 26 is always in close contact with the inner wall of the sanding belt 3, avoiding the sanding belt from being loose or too tight, and ensuring stable contact of the sanding belt during the movement.
