[0018] (3) The exhaust fan is started to extract the heat generated by the hot melt machine through the exhaust pipe, and then the heat is passed into the machine body to dry the cleaned rubber material so that the rubber material remains dry and loose, which is convenient for subsequent processing and treatment. At the same time, the waste heat generated by the hot melt machine is used to dry the rubber material, which can save energy while completing the drying task and reduce production costs. The rubber material to be dried is stirred by rotating the rotating plate to ensure that the rubber material can be in contact with the hot air over a large area to accelerate its drying speed, avoid excessive drying of the rubber surface or incomplete evaporation of internal moisture, and prevent the rubber material from caking or agglomerating during the drying process, resulting in incomplete drying.
