Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle processing, in particular to a blow molding device for plastic bottle processing. Background Art

[0002] The processing of plastic bottles uses the blow molding process. The blow molding machine is used to process the heated and softened preforms to produce plastic bottles. During the processing of the preforms, the heat of the preforms will be lost during the heating and blow molding process, affecting the blow molding effect and prolonging the heating time. This will not only cause a large amount of energy consumption, but also make the preforms too soft. Under the action of gravity, the thickness of the preforms will be uneven, resulting in different quality of the processed plastic bottles. In addition, the plastic bottles are not easy to demold after processing, which affects the production efficiency and the appearance of the plastic bottles. Therefore, we propose a blow molding device for plastic bottle processing. Utility Model Content
