一种高耐热性锂电涂覆隔膜生产用热风循环烘箱

Abstract

本实用新型公开了一种高耐热性锂电涂覆隔膜生产用热风循环烘箱，属于锂电涂覆隔膜加工技术领域。该装置包括热风循环烘箱，所述热风循环烘箱一侧开设有进料口，另一侧开设有出料口，所述热风循环烘箱内部固定设置有用于输送锂电涂覆隔膜的传送装置，所述热风循环烘箱内部靠近进料口一侧设置有预热加热板，靠近出料口一侧设置有主烘加热板。本实用新型在使用时，在涂覆隔膜进入烘箱后，随着传送装置的移动，它逐渐靠近预热加热板。由于预热加热板和主烘加热板倾斜设置，隔膜表面与加热板的接触角度和距离呈渐变状态，这使得热量能够以均匀、线性的方式传递到隔膜上，避免了局部温度骤升或骤降导致的涂层收缩不均问题。
