Heating device for preventing OLED material from being heated and aged

The invention relates to a heating device for preventing an OLED (Organic Light Emitting Diode) material from being heated and aged. The heating device comprises a crucible main body, a heating module, a cooling module and a power mechanism. The crucible main body is filled with a material and comprises an evaporation area positioned at the upper part of the crucible main body and a cooling area positioned at the lower part of the crucible main body. The power mechanism is arranged at the bottom of the crucible main body and is used for pushing the material to move in the crucible main body. The heating device has the beneficial effects that a water cooling assembly is additionally arranged in a heating source, so that the problem that the OLED material in the heating source is heated andaged for a long time is effectively prevented, the quantity of the OLED material added at a time can be greatly increased, a longer feeding period is realized, and the production efficiency is remarkably improved. 本发明为涉及一种防止O
