保鲜膜抽取装置
本专利技术涉及一种保鲜膜抽取装置。
技术介绍
保鲜膜是一种塑料包装制品,通常以乙烯为母料通过聚合反应制成,其成品为卷筒形式,常用于微波炉食品加热、冰箱食物保存、生鲜及熟食包装等场合,在家庭生活、超市卖场、宾馆饭店及工业生产的食品包装领域均有广泛应用。由于保鲜膜厚度较薄,且质地较为坚韧,当人工扯断取用时,在保鲜膜断口处多数会产生不规则的啮齿状结构,不便于使用,可能会导致某段保鲜膜的废弃,造成资源浪费。也有采用齿条切断,但往往造成保鲜膜断口黏连,使得保鲜膜取用不便。
技术实现思路
本专利技术所要解决的技术问题是提供一种保鲜膜抽取装置,本装置克服传统保鲜膜抽取的缺陷,其结构简单,适用多种筒装结构的保鲜膜抽取,确保保鲜膜切断可靠、断口齐整,避免保鲜膜的废弃,节省资源,极大方便了保鲜膜的抽取使用。为解决上述技术问题,本专利技术保鲜膜抽取装置,包括壳体,其特征在于:还包括支撑转轴、固定套筒、固定杆、支撑弹簧、支撑脚、割刀、连接柱、压板、滑块、复位弹簧、两个L形连杆、两个支承块、两根撑杆、两个压块和两个承放台,所述壳体端面设有水平的保鲜膜出口,所述支撑转轴两端设于所述壳体前后内壁,所述固定套筒套入所述支撑转轴,所述固定杆对称设于所述固定套筒外圈且端部设有凹槽,所述支撑弹簧和支撑脚依次设于所述固定杆端部的凹槽内并且支撑脚末端抵靠套入所述固定套筒的保鲜膜卷筒内壁,所述连接柱依次穿过所述压板和壳体顶面,所述滑块设于所述连接柱顶端并且活动嵌入所述压板顶面,所述复位弹簧设于所述压板与壳体顶面之间并且位于压板四角,所述割刀垂直设于所述连接柱底端,所述两个承放台平行设于所 ...
