Preheating mechanism with good energy-saving effect

The utility model discloses a preheating mechanism with a good energy-saving effect, relates to the technical field of liquid glue preheating, and provides the following scheme aiming at the problems that the liquid glue is usually put into a container and then is heated through a heating plate, and only the liquid glue in one container can be preheated, so that the preheating efficiency is low. Comprising a preheating barrel and a barrel cover, the preheating barrel is sleeved with the barrel cover in a threaded mode, three obliquely-arranged supporting legs are fixedly installed on the bottom side of the preheating barrel, and a hand wheel is fixedly arranged on the barrel cover; a motor is fixedly installed on the bottom side of the preheating barrel, and a fulcrum shaft is fixedly connected to an output shaft of the motor. The device is reasonable in design, liquid glue in the four liquid glue containers can be heated and preheated at the same time, heating is uniform, the preheating efficiency is improve
