Bottle preforming device

The preform arraying device includes a body, and at least two first tracks on which a plurality of preforms are successively advanced are arranged on the body, and the first track is arranged on the body parallel to each other in a manner of low, high, and high. The second track spans over the rear end of the first track; the feeding hopper is disposed on the second track and can reciprocate above the rear end of the first track in the direction of the long axis of the second track, and the interior thereof can carry an appropriate amount of preforms. There is a discharge port at the end of the hopper. The position of the hopper and the opening of the discharge port are controlled by the control circuit. This preforming device can significantly increase the production efficiency, reduce the occupied space, and reduce the production cost.
