A bottle blowing machine

Abstract

The present invention discloses a bottle blowing machine. When in use, the preform to be processed is poured into a vibration plate and continuously vibrated by the vibration plate to a material receiving frame. The loading arm clamps the preform to be processed and installs it on a bottle mouth mounting seat. Then, the preform to be processed is blown by a hair dryer. The preform to be processed that is not installed in place is blown off by the wind. Then, the bottle mouth mounting seat drives the preform to be processed to move to correspond to the bottle blowing mold. The left mold and the right mold are tightened toward each other so that the preform to be processed is located in the bottle blowing cavity. The lifting frame is raised to connect the air duct with the through hole. The preform to be processed is blow-molded by the heating effect of the heating device and the blast of the fan. After the blow molding is completed, the bottle mouth mounting seat drives the bottle body to continue to move. The bottle body is photographed and compared by a comparison camera, so as to determine whether the bottle body is qualified. The unqualified bottle body is taken down and recycled by a manipulator. Compared with the prior art, the loading is more stable, and the bottle body after the blow molding is completed can be effectively screened, and the use effect is better.
