[0002] A bottle preform is an intermediate product in the plastic bottle production process. It is formed by injecting plastic particles (such as PET, PE, PP, etc.) into a bottle preform mold under high temperature and high pressure by a plastic injection molding machine. The bottle preform is usually a prefabricated tubular object with the basic shape and size of a bottle, but the bottom and the bottle mouth are not fully formed yet.

[0003] During the turnover process of bottle preforms, it is necessary to ensure that the surface is clean and pollution-free to prevent affecting the quality of the finished product during injection molding. For example, in the prior art, a bottle preform turnover box with the Chinese patent publication number "CN220536218U" includes a bottom plate, a cover body, two first side plates and two second side plates. The two first side plates are movably connected to both ends of the bottom plate at intervals, and the two second side plates are movably connected to both sides of the bottom plate at intervals, so as to form an accommodation cavity for placing bottle preforms at intervals. The first side plate abuts against the first surface of the bottom plate through a first sealing layer, the second side plate abuts against the first surface of the bottom plate through a second sealing layer, and the first side plate abuts against the second side plate through a third sealing layer, which can enhance the sealing performance of the bottle preform turnover box, better store and transport the bottle preforms, and avoid the bottle preforms in the turnover box from being polluted, meeting the requirements of food packaging hygiene.
