Description

Technical Field

[0001] This utility model relates to the field of packaging manufacturing, specifically a one-time forming equipment that integrates blow molding, filling and sealing. Background Technology

[0002] In the blow molding process of plastic bottles, the preform needs to be placed in the predetermined position of the corresponding mold first. Then, the mold is closed, and the preform is heated, blow-molded, cooled, and the mold is opened to produce the required plastic bottle. A search reveals a plastic bottle blow molding equipment disclosed in application number CN202222083752.1, which includes a first mold assembly and a second mold assembly arranged opposite each other, and the two mold assemblies can be assembled into a mold body. The mold body has a mold cavity, and fins extend outward from the outer walls of the two mold assemblies, with heat dissipation space between each pair of adjacent fins. Multiple through holes are opened on the fins, and a heat dissipation pipe passes through the through holes and is coiled in a serpentine manner on the outer wall of the mold assembly. A base is placed below the mold body, and the base... The device has multiple air outlets, which correspond to the heat dissipation space. It uses heat dissipation pipes and fins to cool the mold. At the same time, the upward blowing air from below lowers the temperature of the bottom of the mold, thereby increasing the cooling rate of the plastic bottle after contact with the inner wall of the mold. This ensures that the plastic bottle is in a low-temperature state after mold opening, improving the stability of the plastic and preventing plastic deformation caused by subsequent transfer and processing after mold opening. However, the above description still has the following defects in actual use: the molding equipment cannot trim the opening of the plastic bottle after blow molding, and it lacks continuous operation for subsequent filling and sealing. Therefore, it is necessary to design a practical one-time molding equipment that integrates blow molding, filling and sealing. Utility Model Content
