Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machines, in particular to an equal amount embryo dividing device for bottle blowing machines. Background Art

[0002] When making hollow bottles, a plastic bottle blowing machine is needed. During production, the automatic preform sorting mechanism automatically transports the preforms to the preform separating mechanism, and the preform loading mechanism then places the preforms on the preform separating mechanism onto the heating conveying mechanism to achieve early conveyance of the preforms.

[0003] After searching, it was found that the publication number is CN215619897U, and the name is a slide embryo separation mechanism of a bottle blowing machine. The application proposed a Chinese patent application number 202021012141.2 for a thin-walled positioning ring preform loading mechanism for a plastic bottle blowing machine. There is a single slide corresponding to only one embryo receiving groove, which has low efficiency. When the robot does not process it in time, the preforms may accumulate in the slide, affecting the subsequent transportation of the preforms or the operation of the slide embryo separation mechanism. The embryo separation grooves of the embryo separation assembly divide the preforms in the slide on the conveying assembly into groups equal to the number of embryo receiving grooves, and the lateral reciprocating motion of the embryo separation assembly can make the number of embryo separation grooves less than the embryo receiving grooves, while all the embryo receiving grooves can still be filled in sequence through the embryo separation grooves. Furthermore, multiple batches of bottle preforms in one slide can be processed through the lateral reciprocating motion of the embryo separation groove, the embryo receiving groove and the embryo separation assembly, thereby improving the working efficiency of the embryo separation mechanism of the slide. However, when the application is in use, the upper embryo assembly needs to be full of bottle preforms before it can be flipped over for loading. The reciprocating movement of the embryo separation assembly takes time, which results in a longer operating interval of the upper embryo assembly, reduced work continuity and efficiency, and a more complicated structure, which can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
