Bottle preform heating device

Abstract

The present application relates to the technical field of bottle-blowing, for example, a bottle preform heating device. The bottle preform heating device includes a preform feeding module, a carrier mechanism, multiple heating mechanisms, multiple preform elevating and rotating mechanisms, and an air cooling module. The carrier mechanism includes a rack, a carrier tray and a carrier tray drive assembly, where the carrier tray is rotatably mounted on the rack, and the carrier tray drive assembly is configured to drive the carrier tray to rotate relative to the rack. The multiple heating mechanisms are disposed at intervals in a circumferential direction of the carrier tray, and each heating mechanism includes a heating barrel. The multiple preform elevating and rotating mechanisms are disposed at intervals in the circumferential direction of the carrier tray and are in one-to-one correspondence with the multiple heating mechanisms, and each of the multiple preform elevating and rotating mechanisms is configured to receive a bottle preform conveyed by the preform feeding module and insert the bottle preform into the heating barrel. The air cooling module is configured to extract air from the heating barrel to avoid local overheating of the bottle preform.
