Description

Technical Field

[0001] The utility model relates to the field of bottle preform demoulding, in particular to a bottle preform demoulding device. Background Art

[0002] Plastic hollow containers are widely used in beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price and high safety. They have attracted more manufacturers to choose plastic containers instead of glass containers. Bottle blowing machines are machines that can blow plastic particles or finished bottle blanks into bottles through certain process means. Bottle blowing machines include opening and closing mold mechanisms, bottom molds, lifting mechanisms, bottom mold locking mechanisms and driving mechanisms. After a product is completed, the bottle needs to be demoulded and taken out before proceeding to the next step.

[0003] Conventional devices mostly rely on relatively simple mechanical ejection methods. Due to the lack of precise control during demolding, the force on the preform is extremely uneven. During the demolding process, the preform often deforms due to excessive local force, and scratches are easily generated on the surface, which not only destroys the appearance integrity of the preform, but also damages its internal structure, seriously affecting the quality of the preform, making it difficult to proceed with the subsequent blow molding process smoothly, and the scrap rate remains high. Therefore, we propose a preform demolding device to solve the above problems. Utility Model Content
