Description

一种具有吹风机构的膜包机热缩箱
技术领域
本发明涉及一种具有吹风机构的膜包机热缩箱。
背景技术
膜包成形质量取决于热收缩膜在热缩箱中的收缩效果，其中热缩箱内热空气的流动对收缩效果有很大的影响。同时，不同包型要达到良好的外观质量，其收缩条件也不相同，所以要求热缩箱内的热空气流动可以控制。
参见附图1所示，传统的膜包机中：风机1产生风压，使热空气在固定侧板2和内胆3形成的空气通道内流动，通过内胆3上的吹风口进入热缩箱内，由于固定侧板2和内胆3是依托箱体结构安装的，无法调节，热空气只是单纯地被注入热缩箱内而没有任何流向控制，无法满足不同包型的收缩条件，部分包型的成形质量较差，同时由于上述的无差别吹风，导致整机能耗较高。
