Band saw blade coating equipment and method

The invention relates to the technical field of band saw blade coating, and discloses band saw blade coating equipment and method.The band saw blade coating equipment comprises a main body, a stock bin is fixedly connected to the upper surface of the main body, a hose is fixedly connected to the outer surface of the stock bin, and a spraying device is arranged at one end of the hose. When the band saw blade completely enters the main body, the first motor rotates through meshing of the output end and conducts meshing movement with the tooth block set on the outer surface of the main body, the sliding block slides on the main body to make preparation for follow-up spraying work of the band saw blade, in the moving process, the hose connected with the stock bin can also move along with the main body, and in the moving process, the hose is connected with the stock bin. And when the outer surface of the hose slides relative to a ball in the rolling vessel and moves, traction force can be generated on the rolling
