Description

Technical Field

[0001] The utility model relates to the technical field of PET plastic bottle production and processing, in particular to an automatic turning device for PET plastic bottle production. Background Art

[0002] PET plastic bottles have excellent transparency and gloss, making them suitable for packaging transparent or translucent liquid products, such as beverages, juices, water, etc. Transparency helps consumers intuitively observe the appearance and quality of the product. PET has good chemical resistance and will not react to most food and beverage ingredients, and will not affect the taste or smell of the product. This makes PET plastic bottles very suitable for food and beverage packaging.

[0003] The automatic flipping device can automatically transfer plastic bottles from one manufacturing stage to another, such as from the blow mold to the cooling area, thereby reducing manual intervention and operation time. This helps to improve the overall efficiency and production capacity of the production line. The automatic flipping device can reduce the operation of workers in the manufacturing process, reduce the risk of accidents in operation, and improve the safety of the production site.

[0004] However, most of the flipping devices usually use mechanical grippers to flip the plastic bottles during use. When a large number of plastic bottles need to be flipped during use, the flipping will not be timely, causing the materials to be stuck in the flipping area and unable to enter the next step, resulting in slow production progress and low efficiency.
