Description

Technical Field

[0001] The utility model relates to the technical field of plate surface treatment, in particular to a surface grinding device for processing pine painted plates. Background Art

[0002] Pine painted board is a kind of wood board made of pine wood as raw material. It has the advantages of light weight, easy processing and good stability. Therefore, it is widely used in various painting and decoration projects inside the house. As a natural wood, pine wood may have natural defects such as scars, cracks, burrs, etc. on its surface. During processing, it usually needs to be polished to eliminate the unevenness caused by the early processing such as sawing and planing, to ensure the flatness of the board, and to eliminate the fiber burrs on the wood surface, making the wood texture clearer and more beautiful, and improving the visual effect of the final product.

[0003] Common grinding methods can be divided into manual grinding and mechanical grinding. Mechanical grinding uses sanding machines, etc., which are suitable for grinding some larger areas of boards. However, when grinding boards of different thicknesses, it is necessary to adjust the resistance between the sanding machine and the board. For some smaller areas, they are manually ground with handheld sandpaper or grinding equipment, such as grinders. Although it is convenient for grinding boards of different thicknesses, the pressure during manual grinding is unevenly controlled. The greater the pressure, the more likely the grinding equipment will exert excessive grinding action on a local area of the board, resulting in a large amount of material removal in this area, while other areas are relatively less, resulting in uneven grinding effects on the entire board surface. Based on the above situation, it is necessary to design a surface grinding device for pine painted board processing to solve the above problems. Utility Model Content

[0004] The utility model provides a surface grinding device for processing pine painted boards, which solves the problem of uneven grinding of boards in the prior art.

[0005] The technical problem solved by the present invention is achieved by the following technical solutions:

[0006] A surface grinding device for processing pine painted boards includes a grinding platform, a grinding mechanism and a connecting piece. The grinding platform is provided with a movable component, and the movable component includes a fixed slide rail, a movable slide slidably connected to the fixed slide rail, and a mounting seat slidably connected to the movable slide. The grinding mechanism is located below the mounting seat and is used to grind the board synchronously with the movement of the mounting seat. The connecting piece is used to connect the grinding mechanism to the mounting seat, and the connecting piece can adjust the height position of the grinding mechanism according to the thickness of the board to be polished.

[0007] Preferably, the connecting member includes a connecting plate connected to the grinding mechanism and an elastic member provided on the connecting plate. The connecting plate is slidably connected to the mounting seat, and the other end of the elastic member is connected to the inner top wall of the mounting seat.

[0008] Preferably, the connecting member includes a connecting plate connected to the grinding mechanism and an adjusting rod rotatably connected to the connecting plate.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] Refer to Figures 1-4 As shown, a surface grinding device for processing pine coated boards includes a grinding platform 1. A moving component is provided on the grinding platform 1. The moving component includes a fixed slide rail 2, a movable slide plate 3 slidably connected to the fixed slide rail 2, and a mounting seat 4 slidably connected to the movable slide plate 3. A grinding mechanism 5 is connected to the lower part of the mounting seat 4 through a connecting member 6, which is used to move synchronously with the movement of the mounting seat 4 to grind the board. In order to improve stability, the number of fixed slide rails 2 can be two and they are arranged in parallel. The movable slide plate 3 is slidably connected to the two fixed slide rails 2. The length extension direction of the movable slide plate 3 is perpendicular to the length extension direction of the fixed slide rail 2. The mounting seat 4 can slide along the length extension direction of the fixed slide plate. As Figure 1 shown, the fixed slide rail 2 can be arranged horizontally. The movable slide plate 3 can drive the mounting seat 4 to slide horizontally, and the mounting seat 4 can slide longitudinally on the movable slide plate 3. Through the movement of the mounting seat 4 and the movable slide plate 3, the horizontal and longitudinal movement of the grinding mechanism 5 can be realized, so as to grind the entire surface of the board on the grinding platform 1. The connecting member 6 is used to connect the grinding mechanism 5 with the mounting seat 4, and the connecting member 6 can adjust the height position of the grinding mechanism 5 according to the thickness of the board to be ground, so as to be applicable to grinding boards of different thicknesses. And the grinding mechanism 5 can be driven by the connecting member 6 to fit the surface of the board with a uniform contact force for grinding, avoiding the situation of over-grinding in some areas and under-grinding in other areas, making the roughness of the entire board surface uniform and ensuring the grinding smoothness.

[0021] As Figure 2As shown, the first embodiment provided by the present invention is that the connecting member 6 includes a connecting plate 61 connected to the grinding mechanism 5 and an elastic member 62 provided on the connecting plate 61, the elastic member 62 is preferably a spring, the connecting plate 61 is slidably connected to the mounting seat 4, the other end of the elastic member 62 is connected to the inner top wall of the mounting seat 4, and the number of springs is preferably four, and they are located at the four corners of the connecting plate 61, so that the connecting plate 61 drives the grinding mechanism 5 to generate a uniform downward resistance force, and the grinding mechanism 5 is uniformly subjected to a resistance force on the surface of the plate according to the elastic force of the spring. For thicker plates The thicker the material, the greater the compression force on the elastic member 62, and the greater the resistance force generated by the elastic member 62. However, when the same plate is polished, the resistance force generated is the same, so the uniformity of polishing is also the same, and the connection between the elastic member 62 and the connecting plate 61 and the mounting seat 4 can be set to a detachable connection, so that when polishing according to the thickness of the plate, the length of the elastic member 62 can be adjusted to adjust the resistance force. A pull rod 63 is provided on the connecting plate 61. At the beginning of the polishing work, the polishing mechanism 5 can be driven upward by the pull rod 63 to place the plate underneath.

[0022] like Figure 3 As shown, the first embodiment provided by the present invention is that the connecting member 6 includes a connecting plate 61 connected to the grinding mechanism 5 and an adjusting rod 601 rotatably connected to the connecting plate 61, the connecting plate 61 is slidably connected to the mounting seat 4, one end of the adjusting rod 601 extends to the outside of the mounting seat 4 and is threadedly connected to the mounting seat 4, and the connecting plate 61 is driven up and down by rotating the adjusting rod 601 to adjust the height of the grinding mechanism 5 so that the grinding mechanism 5 fits appropriately on the surface of the plate. Similar to the first embodiment, although both can adapt to plates of different thicknesses and provide uniform resistance force for grinding the same plate, the first embodiment cannot adjust the resistance force between the grinding mechanism 5 and the plate, and the resistance force of the plate can be adjusted by rotating the adjusting rod 601 to drive the grinding mechanism 5 up and down, which is more practical. In the first embodiment, the elastic force of the elastic member 62 is used to make the grinding mechanism 5 fit the surface of the plate, without manual adjustment, which is more convenient and quick.

[0023] Among them, the grinding mechanism 5 may include a driving motor 51 and a grinding disc 52 or a polishing sheet connected to the output shaft of the driving motor 51. The driving motor 51 drives the grinding disc 52 to rotate and contact the surface of the board to be polished to achieve grinding of the board. A blowing blade 7 is also provided on the grinding mechanism 5. The blowing blade 7 is equidistantly arranged along the central axis of the output shaft of the driving motor 51. When the driving motor 51 drives the output shaft to rotate, it drives the blowing blade 7 to rotate to generate a blowing force, blowing the debris ground on the board to other positions to prevent the debris from entering the depressions or gaps of the board. When the grinding disc 52 moves to the position with debris in contact with the board surface, it may be embedded in the wood surface under the pressure of the grinding disc 52, affecting the grinding flatness and smoothness, and may cause the friction between the grinding disc 52 and the board surface to change, affecting the grinding effect and uniformity.

[0024] Further, such as Figure 4 As shown, in order to prevent the plate from being displaced at will during grinding, a fixed limiting tooth plate 21 is provided on the fixed slide rail 2, and a movable limiting tooth plate 22 is movably connected to the fixed limiting tooth plate 21. The number of movable limiting tooth plates 22 can be two, and both are movably connected between the two fixed limiting tooth plates 21, and a telescopic limiting plate 23 is movably connected to the movable limiting tooth plate 22. The number of telescopic limiting plates 23 can also be two, and they are movably connected between the two movable limiting tooth plates 22. The positions of the movable limiting tooth plate 22 and the telescopic limiting plate 23 can be adjusted according to the size of the plate to be grinded. When the distance between the two movable limiting tooth plates 22 is reduced, the length of the telescopic limiting plate 23 is correspondingly reduced to clamp and limit the plate to prevent the plate from moving during grinding. It is suitable for clamping plates of different sizes.

[0025] Furthermore, an extended operating handle 41 is provided on the mounting seat 4. By holding the extended operating handle 41, the mounting seat 4 and the movable slide 3 can be easily moved to any position on the grinding platform 1, which is more convenient and avoids affecting the grinding efficiency due to the operator's insufficient arm span.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
