[0036] The drying mechanism 4 adopts the above technical solution. When in use, the drying mechanism 4 is connected to one side of the coating mechanism 3 through the guide tube 14. When in use, the drying plate 44 dries the coated mesh cloth. The heat generated by the drying is passed through the guide tube 14 to the coating mechanism 3 to preheat and dry the cloth that has just been coated, thereby making full use of the heat and reducing waste. At the same time, the hot air is filtered and absorbed by the filter element 45 to reduce exhaust gas emissions.

During transportation, the mesh cloth is pressed on the tensioning roller 12 by the tensioning force, driving the tensioning slider 23 to press on the pushing spring 24. The tensioning slider 23 and the tensioning roller 12 are pushed by the elastic force of the pushing spring 24 to straighten and flatten the mesh cloth, and after entering the coating box 31, the mesh cloth is supported and transported by the roller 32, and the coating frame 33 is driven to descend by the coating hydraulic cylinder 34 so that the cleaning roller 37 and the coating roller 36 contact the mesh cloth, and the surface of the mesh cloth is cleaned by the dust suction device connected to the dust suction pipe 332 and in conjunction with the dust suction port 373 and the cleaning brush 374, and then Afterwards, the material is introduced into the coating roller 36 through the coating material pipe 333 through the feeding equipment, and then the surface of the mesh is coated by the coating roller 36. At the same time, the hydraulic cylinder 39 is adjusted to drive the scraper 38 to rise and fall and adjust the position according to the coating thickness, so as to facilitate the scraping of the coating material, and the dripping coating material is received by the receiving plate 13, heated by the heating tube 445, and horizontally heat-conducted through the heat-conducting graphite film 444 and the heat-conducting fiber layer 443 to the heat-conducting plate 442 and the heat sink 441, so as to evenly heat and dry the mesh. At the same time, the suction fan 47 runs to exhaust air to extract the exhaust gas generated by drying, and the exhaust gas is filtered and absorbed by the filter element 45, and the air is exhausted by the auxiliary fan 46 through the guide pipe 14 and blown into the coating box 31 to preheat the freshly coated mesh.
