AI Technical Summary

Technical Problem

Disposable cups expand at the rim of the film after heat shrinking, making them impossible to stack and affecting the stacking effect.

Method used

A disposable cup conveying mechanism for a heat shrink machine was designed, including a conveying component and a shaping component. By utilizing the cooperation of a cup support component, a cup stop component, and a cup top component, the cup top component extends into the cup during the conveying process, so that the film adheres to the inner wall of the cup. This ensures that the film tightly wraps the cup opening after heat shrinking, and adapts to the adjustment needs of different cup lengths.

Benefits of technology

This technology enables heat-shrinkable disposable cups to be stacked, improving stacking efficiency and packaging effectiveness, and adapting to the needs of different cup lengths.

Abstract

The utility model discloses a disposable cup conveying mechanism of a heat shrinking machine, which comprises a conveying part and a shaping part, the conveying part comprises a left transmission chain, a right transmission chain and a plurality of cup supporting pieces, the cup supporting pieces are transversely arranged, and the two ends of each cup supporting piece are respectively connected with the left transmission chain and the right transmission chain; the shaping component comprises a plurality of shaping sets, one cup supporting piece is provided with one shaping set, each shaping set comprises a cup blocking piece and a cup jacking piece which are installed on the cup supporting piece, and the cup jacking piece transversely moves relative to the cup blocking piece and extends into a cup. A cup is placed on a cup supporting piece of the conveying component and is conveyed in the discharging direction under the driving of a left transmission chain and a right transmission chain, a cup jacking piece moves towards the cup in the conveying process, a cup blocking piece blocks the cup, the cup jacking piece stretches into the cup, a film at a cup opening enters the cup and is attached to the inner wall of the cup body, in this way, the film enters a thermal shrinkage furnace, and the cup body is wrapped by the film in a shrinkage mode. In addition, the containing cavity with the cup opening is reserved, the disposable cups can be stacked together in a sleeved mode when collected, and stacking of the cups is facilitated.
