Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machines, and particularly relates to a blank returning mechanism of an aligning machine of a bottle blowing machine.

Background Art

[0002] The bottle preform production equipment can produce thousands of bottle preforms per hour, resulting in a large number of bottle preforms being transported to the aligning machine. As shown in the attached Figure 5 figure, currently, the blank returning method of the aligning machine supporting the bottle blowing machine usually adopts the method of using a blank returning pipe 200 or a blank returning chute. This method has requirements for the blank returning landing point and the height of the recovery point of the aligning machine. If the drop height is too small, the sliding angle of the bottle preforms is not enough, which easily causes the bottle preforms to be unable to slide down and get stuck on the blank returning cylinder or the blank returning chute, resulting in the phenomenon of blank accumulation and the inability to achieve the blank returning function.

[0003] In view of this, this case conducts in-depth research on the above problems, and thus this case is generated.
