The present utility model discloses a material preparation device for an injection stretch blow molding machine, relating to the technical field of material preparation for blow molding machines. It comprises a vertical cylinder, a discharge pipe is installed on the bottom wall of the vertical cylinder, an air inlet pipe is installed on the upper wall of the vertical cylinder, a feeding hopper is installed on the upper wall of the vertical cylinder, an exhaust mechanism is installed on the upper wall of the vertical cylinder, and a transmission mechanism is arranged above the discharge pipe. Through the cooperation of the air inlet pipe, exhaust mechanism, transmission mechanism, reflux mechanism and cleaning mechanism, the air inlet pipe can first fill sufficient hot air into the vertical cylinder, and when the air pressure inside the vertical cylinder is too high, the gas inside the vertical cylinder can be discharged through the exhaust mechanism, so that the raw materials inside the vertical cylinder are always kept in a high-temperature environment without solidification, solving the problem that raw materials are prone to solidification when placed in the feeding hopper for a long time, which affects subsequent product processing.
