  • Patent number: 11840007
    Abstract: Provided are a handle-orienting preform feeding mechanism and orienting preform feeding method for a bottle preform with a handle. Under the combined action of the axial rotation of a plastic bottle preform and a handle positioning structure on a preform feeding tray, the handle of the plastic bottle preform with an integrated handle (especially a PET plastic bottle preform with an integrated handle) is positioned so that the plastic bottle preform with an integrated handle enters a heating machine and a bottle blowing machine of the next process according to the predetermined orientation. Accordingly, the wrong orientation of the integrated handle of the plastic bottle preform is avoided so that a mechanical arm can grasp the plastic bottle preform correctly and place the plastic bottle preform at the correct position of a bottle blowing mold. Thus the plastic bottle preform can be blown successfully.
