This invention relates to a material feeding device for an injection blow molding machine, which includes an injection blow molding mechanism. The injection blow molding mechanism is a three-station injection blow molding machine, comprising three stations: preform preparation, inflation, and demolding, with each station spaced apart.120°It also includes a demolding assembly, a buffer groove, and a material chute. The demolding assembly is driven by a cylinder and slidably disposed in the groove along the opening direction of the groove. The buffer groove is disposed on one side of the support base, below the demolding assembly. The material chute is connected to the buffer groove along its length. This invention, by setting a feeding mechanism, first makes the bottle rotate at a constant speed to the demolding area during demolding, and then flexibly contacts the buffer groove. While the bottle slides down the buffer groove, the bottle is cooled by the air-cooling mechanism. This solves the technical problem of damage to the bottle shape due to rigid contact between the bottle and the collection frame during demolding in traditional injection blow molding, and improves product quality.
