Description

Technical Field

[0001] The invention relates to the technical field of plate processing, in particular to a plate grinding and polishing device for interior decoration. Background Art

[0002] In the field of interior decoration, curved panels are increasingly favored by designers and owners due to their unique aesthetic effects and space-shaping capabilities. From elegant curved wall decorations to uniquely shaped furniture components, curved panels add soft and smooth lines to the interior environment, breaking the monotony of traditional straight lines and creating a more flexible and warm space atmosphere. However, curved panels face many challenges in grinding and polishing, which seriously restricts their wide application and effect presentation in interior decoration.

[0003] Traditional grinding equipment is mainly designed for flat panels and is difficult to adapt to the complex curved surface features of curved panels. Common flat grinders have a fixed flat structure for their grinding heads. When they come into contact with curved panels, they can only achieve effective grinding in a limited area. Most areas of the curved surface of the panel cannot be fully processed, resulting in extremely uneven grinding effects, which seriously affects the surface quality and decorative effects of the panel. Taking the curved wood panels commonly used in furniture production as an example, when using traditional grinding equipment, the curved surface is often over-grinded or under-grinded, which not only wastes materials, but also requires a lot of manual follow-up repairs, greatly increasing production costs and time costs.

[0004] The problems are also prominent in the polishing process. The polishing of curved plates requires precise control of the polishing force and angle to ensure that the entire curved surface has consistent gloss and smoothness. However, the existing polishing devices lack the ability to adapt to the curvature of the curved surface, and the polishing wheel cannot fit the curved surface tightly for uniform polishing, resulting in gloss differences and minor scratches on the surface of the plate, reducing the overall quality of the plate. For curved metal plates used for wall decoration in interior decoration, if the polishing is uneven, obvious light spots and shadows will appear under the light, which greatly damages the beauty of the wall and makes it difficult to meet the stringent requirements of high-end interior design.

[0005] In addition, positioning and fixing of curved plate during grinding and polishing is also a major problem. Due to the irregular shape of the plate, it is difficult to place it stably on the equipment, and it is easy to shift and shake during the processing, further affecting the grinding and polishing accuracy. Therefore, a plate grinding and polishing device for interior decoration is proposed to solve the above problems. Summary of the invention

[0017] (III) Beneficial effects Compared with the prior art, the present invention provides a grinding and polishing device for indoor decoration plates, which has the following beneficial effects: 1. The grinding and polishing device for interior decoration boards adopts adaptive pressure adjustment. The U-shaped plate and the sliding shell are elastically connected by a spring. During the grinding process, the spring enables the U-shaped plate to float along the guiding arm. When the grinding roller touches different curvature parts of the arc-shaped board, it can automatically adjust its position to ensure that the grinding roller always fits the curved surface of the board with a constant pressure, further guaranteeing the uniformity of the grinding and polishing effect.

[0018] 2. The grinding and polishing device for interior decoration boards adopts uniform grinding and polishing along the generatrix. The grinding roller of the grinding and polishing part can grind along the texture direction of the generatrix of the board. The second motor drives the rotating rod to drive the grinding roller to rotate. At the same time, the linear motor adjusts the Y-axis direction of the sliding seat, enabling the grinding roller to fully cover the curved surface of the board, avoiding uneven grinding, and effectively improving the flatness and gloss consistency of the board surface.

[0019] 3. The grinding and polishing device for interior decoration boards adopts that the two supports of the distance adjustment part are adjusted in distance by the first electric push rod. At the same time, the first rotating shaft rotatably connected to the support can cooperate with the first handwheel to adjust the angle, which is convenient for loading. After adjusting the distance, it is fixed in position through the lock rod and the lock hole on the first rotating shaft, and it can adapt to arc-shaped boards of different lengths. The bidirectional screw of the clamping part rotates to drive the two clamps on both sides to move along the positioning rod, thereby adjusting the distance between the clamps and realizing the stable clamping of arc-shaped boards of different widths, improving the versatility of the device.

[0020] 4. The grinding and polishing device for interior decoration boards adopts automatic positioning of the processing area. The first induction device installed on the top of the support serves as the infrared sensor transmitting end, and the second induction devices installed on both sides of the outer wall of the sliding shell serve as the infrared sensor receiving ends. When the screw drives the threaded socket head to move, when the second induction device on one side of the sliding shell aligns with the first induction device on the same side, an electrical signal is generated to drive the first motor to reverse. In this way, the grinding and polishing range can be automatically positioned according to the distance between the two supports, realizing reciprocating processing, ensuring the precise control of the processing area, and avoiding over-processing or under-processing.

[0021] 5. The grinding and polishing device for interior decoration boards adopts a pluggable lock rod. Rotating the first handwheel drives the clamping plate to flip 180°, which can change the clamping direction of the arc-shaped board. After the outer arc surface of the board faces downward, it is supported by the anti-slip pad on the hydraulic rod, and the inner arc surface of the board can be ground and polished by the grinding roller, expanding the processing range of the device.

[0022] 6. The grinding and polishing device for interior decoration boards has a grinding roller detachably installed on the mounting plate and the rotating rod, which can be easily replaced according to actual grinding requirements. For example, the grinding roller can be replaced with a polishing roller, enabling a single device to have multiple processing functions, reducing the equipment purchase cost. The various adjustment components of the device, such as electric push rods, handwheels, motors, etc., have simple and easy-to-understand operation methods. Ordinary workers can operate them proficiently after simple training, reducing labor costs and operation difficulties, and improving production efficiency. Brief Description of the Drawings
