[0003] The blowing process of plastic bottles is divided into one-step and two-step. The two-step blowing process is relatively widely used because of its high machine output, but the one-step blowing process has advantages in energy saving because it utilizes the residual heat of the preform.

[0036] like Figure 1As shown, the linear injection-blowing integrated plastic bottle forming equipment of this embodiment includes an injection molding module 100 for injection molding rows of blanks and a blowing module 200 for simultaneously blowing the rows of blanks to form rows of plastic bottles. The injection molding module 100 and the blowing module 200 are arranged in sequence in a linear manner, and the arrangement direction of the rows of blanks injection-molded by the injection molding module 100, the arrangement direction of the rows of plastic bottles formed by blowing the bottles by the blowing module 200, and the arrangement direction of the injection molding module 100 and the blowing module 200 are arranged in the same direction; the linear injection-blowing integrated plastic bottle forming equipment also includes a transfer mechanism 300 for translating the rows of blanks molded and output by the injection molding module 100 to the blowing module 200. The linear injection-blowing integrated plastic bottle forming equipment of the present invention is characterized in that the injection molding module 100 injection molds the blanks arranged in rows, and then the transfer mechanism 300 simultaneously clamps the injection-molded rows of blanks and transfers them to the next station in a translational manner; the transfer mechanism 300 translates the rows of blanks into the bottle blowing module 200, and the bottle blowing module 200 simultaneously blows the rows of blanks, and then the transfer mechanism 300 removes the rows of plastic bottles that have been blown in rows, thereby realizing the entire plastic bottle manufacturing process; the required temperature of the rows of blanks due to the movement from the injection molding module 100 to the bottle blowing module 200 is comprehensively guaranteed by the spacing between the injection molding module 100 and the bottle blowing module 200, the translation transfer speed of the transfer module, and the working environment temperature of the entire plastic bottle molding equipment. The entire plastic bottle production process, conveying process, and driving method are simple and single. The injection molding module 100 injection molds rows of blanks, which are then translated as a whole to the bottle blowing module 200 for bottle blowing. The resulting rows of plastic bottles are output as a whole, and the transfer mechanism 300 only needs to perform reciprocating translational movements. In addition, due to the use of a linear injection-blowing integrated process, there is less interference and restriction between the various process links, and the number of blanks in a row and the number of plastic bottles in a row obtained are not easily restricted by space. It is easy to achieve multiple rows of plastic bottles, or even multiple rows of the same batch production, so the output can be doubled or even dozens of times increased, providing a favorable process basis for the large-scale and rapid production of various types of plastic bottles. Figure 1As shown, the injection molding machine realizes the diversion of injection materials through the injection pipe, and enters the material flow path of multiple blank mold assemblies respectively, thereby realizing blank molding in the blank molding cavity of the blank mold assembly. Preferably, the number of blank mold assemblies is two groups. Optionally, the injection pipe itself has a heat preservation and heat insulation function, and a heating pipe clamp can be arranged outside the injection pipe when necessary. Optionally, the blank molding cavities in the blank mold assembly are arranged in a single row, and each blank molding cavity is arranged at intervals from each other, and the number of single-row blank molding cavities is 3-20.
