AI Technical Summary

Technical Problem

In the existing technology, the bottle preforms need to be manually moved at regular intervals during feeding to prevent accumulation, which cannot make full use of the volume of the feeding frame cavity.

Method used

A swing mechanism for the feeding frame is adopted, which uses a drive motor to drive the rotating shaft and the swing frame to swing back and forth to prevent bottle preforms from accumulating. A buffer layer reduces collision noise, a stroke sensor controls the swing amplitude, and an infrared transmitter monitors the feeding situation to achieve automated operation.

Benefits of technology

It achieves automated and uniform distribution of preforms, avoids accumulation, makes full use of the feed frame volume, reduces manual intervention, lowers noise and improves production efficiency.

Abstract

The utility model relates to the technical field of blanking, disclose a kind of swing mechanism for blanking frame, including support, drive assembly being set on support, the pivot of drive assembly connection with drive assembly through transmission component, and the end of pivot is fixedly connected with swing frame;The lower part of the front side of swing frame is provided with a support beam, and the upper surface of support beam is used to support the bottom of blanking frame;The drive assembly is used to drive the swing frame reciprocating swing left and right by the pivot.The pivot is rotated by driving motor, and the swing frame and support beam are driven by the pivot, and the blanking frame placed on the support beam reciprocating swing action left and right, through the above-mentioned continuous swing action, bottle embryo cannot be excessively accumulated in a position in blanking frame, to effectively prevent bottle embryo from being accumulated too high, and reduce the number of blanking frame containing bottle embryo.In addition, in the swing process, bottle embryo in blanking frame can also be displaced to fully fill the gap between bottle embryo and bottle embryo, further utilize the volume of blanking frame.
