The invention discloses a heating device for evaporation and evaporation equipment, and relates to the field of display device manufacturing. The heating device for evaporation and the evaporation equipment can solve the problems that existing evaporation equipment is not uniform in heating, evaporation material is easily sprayed, performance deterioration of the evaporation material occurs easily, and stabilization is difficult in the process of adjusting the evaporation rate. The heating device for evaporation comprises a crucible, a movable heating unit, a weighing sensing device and a controller; the crucible is used for containing the raw evaporation material; the movable heating unit is arranged outside the crucible and is higher than the raw evaporation material in the evaporation process; the weighing sensing device is arranged below the crucible and is used for weighing the crucible and the raw evaporation material in the crucible and outputting the weight data; the controller is used for receiving the weight data output by the weighing sensing device, the liquid level height of the raw evaporation material in the crucible can be calculated according to the weight of the crucible and the raw evaporation material in the crucible, and the movable heating unit can be controlled to reach the height of the raw evaporation material according to the liquid level height.
