After the wiping roller 710 has finished wiping and cleaning the surface of the wood body 5, the heating tube 97 can be started for heating, and at the same time, the fourth motor 96 is started to drive the fan blades 95 to rotate inside the wind guide cover 94, so that the external wind is sucked into the inside of the wind guide cover 94, and then enters the inside of the wind guide frame 93 and passes through several heating tubes 97, and contacts the surface of the heating tubes 97, so that heat exchange occurs and the temperature of the wind is increased. Finally, the wind is discharged from the jet hood 91 and blown to the surface of the wood body 5, and its surface is dried to prevent the cleaning agent from wetting the wood and affecting the subsequent polishing, thereby improving the polishing efficiency and effect. It should be particularly noted that the heating tube is a mature heating technology means and equipment in the prior art. In this scheme, its heating function is used, and its internal structure, connection method and principle are no longer elaborated. The drying device 9 also includes a plurality of filter screens 98, wherein a plurality of filter screens 98 are respectively fixedly installed in the inner walls of several outlets of the jet hood 91. The inner walls of several outlets of the jet hood 91 can be protected to prevent external dust and impurities from entering and causing blockage, while also preventing the dust absorbed by the fan blades 95 from being blown out.

[0034] The working principle is as follows: first, according to the diameter size of the circular wood body 5 to be polished, the telescopic frame 61 is adjusted to a certain height, and then it is fixed with bolts, and then the wood body 5 to be polished is placed on the placement plate, so that one side of it abuts against one side of the clamping plate 66 fixed by the second motor 65, and at this time, the second cylinder 67 is started to drive the other clamping plate 66 to move to one end, and the wood body 5 is clamped and fixed between the two clamping plates 66, and finally the first cylinder 63 is started to drive the slide 64 to slide in the direction of the polishing roller 2 on the polishing machine 1, and at the same time, the second motor 65 is started to drive the clamping plate 66 to rotate and move in the direction of the polishing roller 2. When it is transported to a certain position, the sprocket brush roller 73 will be squeezed by the limit plate 716, so that it drives the first rectangular rod 72 to slide downward in the inner wall of the slide groove 741, thereby driving the telescopic rod 742 and the spring 743 to contract, and at the same time, the spring 743 will drive the first rectangular rod 72 and the sprocket brush roller 73 to reset, so that it is always close to the wood body. The surface of the wood body 5 is convenient for cleaning the surface of the wood body 5 of different sizes, so that it can achieve the effect of automatic adjustment, and it is convenient to clean the surface of the wood body 5 of different diameters, and then start the fan 84 to absorb air into the guide tube 83 through the first dust suction cover 81 and the second dust suction cover 82, drive the sprocket impeller rod 751 to rotate, drive the second chain 753 to rotate, and then drive one of the sprocket brush rollers 73 to rotate, so that under the transmission of the first chain 752, it can drive another sprocket brush roller 73 to rotate, so that it is opposite to the rotation direction of the wood body 5, and brush its surface to clean the dust and impurities attached to its surface, so that the grinding roller 2 can smoothly contact the surface of the wood body 5, avoid uneven grinding, and improve the quality of the wood body 5 after grinding. The cleaned dust and impurities will be sucked into the guide tube 83 by the first dust suction cover 81, and then transported to the inside of the threaded tube 85 with the help of the fan 84, and finally enter the inside of the cloth bag 86 for collection; Then, when the wood body 5 is transported to the bottom of the wiping roller 710, similarly, the height of the wiping roller 710 is adjusted with the help of the adjusting mechanism 74, and then the water pump 713 and the third motor 711 are started at the same time, the water pump 713 will draw the cleaning agent inside the liquid storage barrel 712 into the first hose 714, and then the cleaning agent will flow into the interior of the hollow rod 77 through the through hole 79 inside the circular ring block 715, and finally be discharged from a plurality of circular holes 78 to penetrate into the interior of the wiping block and soak it, and then the third motor 711 will drive the wiping roller 710 and the hollow rod 77 to rotate on the second rectangular rod 76, so that it rotates in the opposite direction to the wood body 5, and wipes and cleans its surface. Wash and clean, clean the oil stains attached to its surface, avoid adhesion to the grinding roller 2 in the later stage, causing blockage, improve the grinding efficiency and effect of the wood body 5, avoid damage to the grinding equipment, and increase the service life of the equipment; at the same time, start the heating tube 97 for heating, and start the fourth motor 96 to drive the fan blades 95 to rotate inside the wind guide cover 94, suck the external wind into the interior of the wind guide cover 94, and then enter the interior of the wind guide frame 93 to pass through several heating tubes 97, contact with the surface of the heating tube 97, heat exchange occurs, and the temperature of the wind is increased, and finally discharged from the jet hood 91 to blow to the surface of the wood body 5, and its surface is dried.

[0035] Finally, when the wood body 5 is transported to a certain position, the first motor 3 is started to drive the grinding roller 2 to rotate at a high speed on the grinder 1 and inside the protective cover 4. Then, when the surface of the wood body 5 is in close contact with the outer surface of the grinding roller 2, its surface can be polished. The grinding debris will pass through the second dust suction cover 82, be absorbed into the guide pipe 83, and finally enter the cloth bag 86 for collection, which is convenient for later processing.
