[0001] The utility model relates to the field of injection molding, and particularly relates to a feeding device for an injection molding machine. Background Art

[0002] In a fan production line, since the capacity of the temporary storage hopper of the injection molding machine is small, a method of hoisting a ton bag and slowly discharging the material from the opening of the ton bag is usually adopted to continuously feed the temporary storage hopper, so as to ensure that the injection molding machine can continuously produce; when discharging the ton bag, it is necessary to hoist the lifting belt at the bottom of the ton bag by a hoisting mechanism to make the opening of the ton bag face downwards, and the feeding personnel need to control the discharging speed of the ton bag by controlling the size of the opening; the ton bag after loading the material has the characteristics of heavy weight and large volume.

[0003] However, during transportation and handling, it is inevitable to drag the ton bag, resulting in wear of the lifting belt. When the lifting belt is hoisted for a long time, the severely worn lifting belt will break, causing the ton bag to fall. If the operating personnel are operating on the opening of the ton bag at this time, the falling ton bag will press on the operator's arm, causing personal injury. Summary of the Utility Model
