Efficient hot air circulation structure of tunnel furnace

Abstract

The utility model discloses a kind of tunnel furnace efficient hot air circulation structures, it is related to tunnel furnace technical field, including base, the inside of base is provided with heating band, the top of base is fixedly connected with tunnel, the top of tunnel is provided with top plate, the bottom between the side of tunnel and top plate is fixedly connected with L type board, the side of base is provided with exhaust fan, the both sides of exhaust fan are fixedly connected with air inlet pipe and air outlet pipe respectively, the inside of tunnel is provided with first tensioning roller and second tensioning roller respectively, the top of top plate is provided with adjusting assembly. The utility model discloses a kind of tunnel furnace efficient hot air circulation structures, by introducing adjusting assembly, first telescopic cylinder and second telescopic cylinder can be in real time adjustment first tensioning roller and second tensioning roller position when tunnel furnace operation, without stopping work, effectively improve production efficiency, shorten cycle. Real-time adjustment ensures that rubber drying is moderately tensioned, avoid wrinkle and uneven drying problem.
