AI Technical Summary

Technical Problem

Existing sealing and cutting mechanisms are time-consuming to transfer materials between production processes, making it difficult to meet the demands of modern high-speed continuous production. Furthermore, the sealing and cutting actions are prone to misalignment or tilting, leading to seal cracking or slow production pace.

Method used

The heat-sealing and cutting cylinders are controlled synchronously by PLC, combined with a mechanical guide design to ensure automatic cutting within 0.5-1 seconds after heat sealing. Elastic rubber positioning baffles limit the offset of the packaging bag, and the serrated cutting blade cooperates with the guide hole to achieve precise connection between sealing and cutting, and adapt to the heat sealing temperature adjustment of packaging bags of different materials.

Benefits of technology

It achieves precise connection between sealing and cutting, improves production efficiency, reduces scrap rate, adapts to the production needs of multiple types of packaging bags, and ensures sealing and verticality of the cut.

Abstract

本实用新型属于包装袋技术领域,尤其涉及一种包装袋封口切断机构,包括底座和垂直固定在底座顶部一侧的支撑板,所述支撑板从上至下依次设置有切断组件和热封组件,所述热封组件包括固定在底座上方的下模具、与下模具对应设置的上模具,以及驱动上模具运动的热封驱动件。该包装袋封口切断机构实现了通过“PLC同步控制+机械导向”双重设计,解决传统集成设备“动作错位、切口倾斜”的问题,实现动作精准衔接,严格限制切断刀竖直运动轨迹,避免切断切口倾斜;可限制包装袋横向偏移,确保封口位置与切断位置对齐,下模具内置加热丝并电连接温度控制器,可根据塑料、复合膜等不同材质包装袋的热封需求。
