Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, specifically to a sandpaper mounting device for mechanical grinding equipment. Background Technology
[0002] As is well known, mechanical sanding equipment is widely used in fields such as construction and wood processing. Mechanical sanding equipment uses a high-speed rotating motor to drive the end head equipped with sandpaper to rotate, so as to achieve the purpose of rapid sanding.
[0003] Existing sandpaper mounting devices have significant shortcomings: when installing sandpaper, the two ends of the sandpaper are usually fixed only by clamping structures, while there is a lack of effective means of fixing the middle area of the sandpaper to the mounting device. This design causes the middle part of the sandpaper to bulge or shift due to centrifugal force or grinding pressure during high-speed grinding, and even gaps may appear between it and the surface of the mounting device. This not only causes uneven force on the grinding surface and reduced accuracy, but may also cause abnormal noise or excessive wear due to local vibration of the sandpaper, seriously affecting the installation stability and grinding effect, and making it difficult to meet the needs of high-quality grinding operations.

The mounting point is located on the top of the mounting block. The bottom of the auxiliary plate is provided with an adhesive layer. The auxiliary plate is connected to the mounting block through the connecting mechanism. The connecting mechanism includes a T-slot, a T-block, a through groove, an electric push rod, and a limiting plate. The T-slot is formed on the mounting block. One end of the T-block extends into the T-slot, and the other end of the T-block is connected to the auxiliary plate. The through groove is formed in the T-block. One end of the electric push rod is connected to the inner wall of the through groove, and the other end of the electric push rod is connected to the limiting plate. Both ends of the limiting plate are in contact with the two sides of the mounting block. Two connecting mechanisms are provided.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a sandpaper mounting device for mechanical grinding equipment, which has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figure 1-4 A sandpaper mounting device for mechanical grinding equipment includes a mounting block 1, a mounting point 2, an auxiliary plate 3, a connecting mechanism 4, and a clamping mechanism 10. The mounting point 2 is located on the top of the mounting block 1. The bottom of the auxiliary plate 3 is provided with an adhesive layer. The auxiliary plate 3 is connected to the mounting block 1 through the connecting mechanism 4. The connecting mechanism 4 includes a T-slot 5, a T-block 6, a through groove 7, an electric push rod 8, and a limiting plate 9. The T-slot 5 is formed on the mounting block 1. One end of the T-block 6 extends into the T-slot 5, and the other end of the T-block 6 is connected to the auxiliary plate 3. The through groove 7 is... In the T-shaped block 6, one end of the electric push rod 8 is connected to the inner wall of the through groove 7, and the other end of the electric push rod 8 is connected to the limiting plate 9. The two ends of the limiting plate 9 are respectively in contact with the two sides of the mounting block 1. There are two connecting mechanisms 4. The clamping mechanism 10 includes a sliding component 11 and a clamping plate 12. The sliding component 11 is disposed on the side of the mounting block 1, and the clamping plate 12 is disposed on the sliding component 11. There are two clamping mechanisms 10. The auxiliary plate 3 is provided with a control button 13, and the control button 13 is electrically connected to the electric push rod 8.
[0023] like Figure 1 As shown, the working principle of the sandpaper installation device is as follows: The operator first attaches the sandpaper to the adhesive layer at the bottom of the auxiliary plate 3, and fixes the middle area of the sandpaper through the adhesive layer; since the sandpaper has long extensions at both ends, it can be folded upwards so that the folded ends are attached to the top surface of the auxiliary plate 3. Then, the sliding component 11 is activated to drive the clamping plate 12 to move downwards until the clamping plate clamps the folded parts at both ends of the sandpaper, thus completing the overall fixation of the sandpaper.
[0024] After installation, connect the mounting point 2 on the top of the mounting block 1 to the output end of the external grinding equipment, and it can be put into use (the specific connection method is a conventional technology in this field, and will not be described in detail here). When not replaced, the sandpaper can be fixed on the auxiliary plate 3 for a long time. When idle, a protective film can be covered on the surface of the adhesive layer to avoid dust from affecting the bonding effect.
[0025] When sandpaper needs to be replaced, the sliding component 11 is controlled to lift the clamping plate 12, separating the clamping plate from both ends of the sandpaper. The operator can then gently peel off the sandpaper to completely detach it from the adhesive layer. The adhesive layer is reusable and has stable adhesion. If the adhesive layer of the auxiliary plate 3 fails due to long-term use and needs to be replaced, the procedure is as follows: The electric push rod 8 is activated by the control button 13 on the auxiliary plate 3, driving the limit plate 9 to retract upwards. When the electric push rod 8 retracts to its limit position, the limit plate 9 separates from both sides of the mounting block 1, and its size is perfectly matched to the opening of the T-slot 5. At this time, the auxiliary plate 3 is pulled, allowing the T-block 6 and the limit plate 9 to slide out along the T-slot 5, and the auxiliary plate 3 can be removed and replaced with a new auxiliary plate (containing a new adhesive layer, which can be provided by the manufacturer). The installation steps are well known to those skilled in the art and will not be described in detail here.
[0026] To improve the gripping effect of the clamping plate 12 on the sandpaper and prevent slippage during sanding, an anti-slip layer is added to the bottom of the clamping plate 12 in this embodiment. The anti-slip layer is fixedly connected to the bottom of the clamping plate 12 and is firmly bonded to the silicone clamping plate through a vulcanization process to prevent delamination and peeling during long-term use. The surface of the anti-slip layer is processed with fine diamond-shaped patterns, which can increase the contact friction with the folded end of the sandpaper. At the same time, the air on the contact surface is discharged through the gaps in the patterns, forming a "vacuum adsorption" effect to enhance the gripping stability. This design ensures that the sandpaper will not shift due to vibration or force during high-speed sanding, which not only improves the sanding accuracy but also reduces the wear of the sandpaper edges caused by slippage.
[0027] To further enhance the anti-slip effect, the clamping plate 12 in this embodiment is made of silicone. Silicone has excellent elasticity and coefficient of friction. When it comes into contact with the folded end of the sandpaper, it can produce moderate deformation, increasing the contact area and forming a tight wrap. This effectively counteracts the radial force generated during sanding, preventing the sandpaper from slipping. Its softness reduces the hard pressure on the surface of the sandpaper, preventing damage at the clamping point. At the same time, the wear resistance and temperature resistance of silicone are suitable for the frictional heat environment during sanding, and can maintain a stable clamping force for a long time. This material selection, combined with the anti-slip layer, forms a double anti-slip guarantee, ensuring that the sandpaper remains in a stable position during high-speed rotating sanding, improving the reliability and safety of the sanding operation.
[0028] To improve the stability of the device connection, the T-slot 5 and T-block 6 in this embodiment adopt a precise matching design. The dimensional tolerances of the two are strictly controlled to ensure that the T-block 6 forms a tight fit after being embedded in the T-slot 5. There is no excessive gap that would cause shaking, while retaining the necessary sliding margin to facilitate the installation and removal of the auxiliary plate 3. This structural constraint allows the T-block 6 to move only along the extension direction of the T-slot 5, limiting the horizontal offset. Combined with the lateral positioning of the limiting plate 9, it effectively prevents the auxiliary plate 3 from being displaced due to vibration during the grinding operation. The precisely matched T-structure can also disperse the driving force of the electric push rod 8, avoiding excessive local stress that could cause component deformation. This provides a reliable guarantee for the stable installation and convenient replacement of the auxiliary plate 3, thereby improving the overall operational stability of the device.
[0029] To improve the overall stability of the device, in this embodiment, the two connecting mechanisms 4 are symmetrically distributed and assembled on both sides of the mounting block 1. This symmetrical arrangement ensures that the auxiliary plate 3 is subjected to balanced force when connected to the mounting block 1, avoiding tilting or offset caused by excessive force on one side, and ensuring that the auxiliary plate 3 always remains horizontal, thereby guaranteeing the flatness after sandpaper installation. At the same time, the symmetrically distributed connecting mechanisms 4 can balance the sliding load of the T-block 6 in the T-slot 5, reduce unilateral wear, and extend the service life of the components. In addition, the synchronously moving connecting mechanisms 4 on both sides can improve the smoothness of the loading and unloading process of the auxiliary plate 3, prevent jamming caused by asynchronous movement on both sides, provide stable structural support for sandpaper replacement and auxiliary plate maintenance, and ensure the continuity and reliability of the grinding operation.
[0030] To improve the stability of sandpaper installation, in this embodiment, two clamping mechanisms 10 are symmetrically distributed on both sides of the mounting block 1. This symmetrical design ensures that both ends of the sandpaper are subjected to balanced clamping force, preventing sandpaper shifting or wrinkling due to uneven force on one side. This ensures that the sandpaper remains flat and in good contact with the auxiliary plate 3. At the same time, the symmetrically distributed clamping mechanisms 10 can balance the driving force of the sliding component 11, reduce wear on one side of the component, and extend the service life of the clamping structure. In addition, the clamping mechanisms 10 that move synchronously on both sides can improve the consistency of operation, ensuring that the forces on both ends are synchronized when loading and unloading sandpaper, preventing sandpaper shaking caused by loosening on one side first. This provides a reliable guarantee for the stable fixation of sandpaper during the sanding process and effectively improves the overall operational stability of the device.
