Description

Technical Field

[0001] This invention relates to the field of rosewood processing technology, and in particular to a rosewood processing and polishing equipment and its control method. Background Technology

[0002] In the traditional furniture making process, after the entire piece is assembled, each component is individually sanded using tools such as scrapers, planes, burrs, straw, and hemp fibers until all four sides are smooth. Sanding techniques include scraping, polishing, and wet sanding. Modern sanding processes incorporate many new tools, such as sandpaper, angle grinders, and belt sanders.

[0003] Polishing is a crucial step in furniture making; there's an old saying that goes, "Three parts carving, seven parts polishing." This is because the lines and surfaces of furniture need polishing to finalize their shape, and the spirit of the carving is perfectly brought out through polishing. Finely polished furniture is not only smooth and rounded like a baby's skin, with vivid and lifelike carvings, but it's also incredibly translucent, showcasing the natural grain and texture of the wood to its fullest extent.

[0004] However, the polishing process is usually done manually, relying entirely on experience, and requires high technical skills from the operator. Therefore, there is an urgent need for a mahogany processing and polishing equipment that can replace manual labor with machinery and ensure consistent polishing quality. Summary of the Invention

[0065] like Figure 3 As shown, the grinding device 120 includes: a support frame 121, a first conical wheel mechanism 122 and a second conical wheel mechanism 123. The first conical wheel mechanism 122 is rotatably supported on the support frame 121; the second conical wheel mechanism 123 is rotatably supported on the support frame and has a gap with the first conical wheel mechanism 122.

[0066] like Figure 4 As shown, the first conical wheel mechanism 122 includes: a first conical wheel 1221, which is conical and has multiple annular grooves on its surface; a second conical wheel 1222, which is conical and has multiple annular grooves on its surface, and is arranged parallel to the first conical wheel; multiple synchronous sanding belts 1223, which are sleeved on the first conical wheel and the second conical wheel; and a first limiting wheel 1224, which is detachably mounted on the support frame to prevent the synchronous belts from curving; wherein, the surface of the synchronous sanding belt is sandpaper, and the surface roughness of each sanding belt is different.

Under a high-magnification electronic scanning microscope, their roughness was similar and the polishing effect was good.

[0078] In a preferred embodiment, since the required surface roughness of the workpieces varies, an empirical formula for grinding is provided in this embodiment:

[0079]

[0080] Where v0 represents the travel speed of the wood conveyor on the conveyor table, Ra0 represents the original roughness before sanding, and Ra e Indicates the target roughness after polishing, e δ This represents the grinding correlation coefficient, where F represents the applied pressure of the grinding conical wheel structure, and v a The value represents the rotational speed of the conical wheel mechanism, t represents the grinding time, and K represents the grinding grit size.

[0081] Among them, e δ It is positively correlated with the number of applications, the particle size of the grinding belt, the length of the grinding belt, and the tension of the grinding belt. It can be derived based on empirical test data or solved by establishing a linear regression equation.
