Description

一种流延设备用吸风装置 技术领域
本发明涉及流延膜加工设备技术领域，尤其是指一种用于流延设备冷辊上的负压吸风装置。
背景技术
流延膜的生产工艺是熔融的塑料经挤出后通过模头前端的缝隙流出，形成薄膜，离开模头后，熔体经过一个短的间隙，到达低温的流延辊面而急剧冷却定型，再经牵引、切边后把制品收卷，最终得到具有一定韧性的薄膜，其广泛用于食品、纺织品、化工产品、日用品等的包装。
为了避免流延辊在转动时，将空气带入薄膜与冷辊之间，产生气泡，降低冷却效果并影响薄膜的成型质量，同时为了使流延膜能够很好的贴附在冷辊表面，通常在冷辊上方设置流延膜生产用负压吸风装置，保证熔融薄膜与冷辊的紧密接触，提高塑料薄膜的成型效果和质量。
目前，国内的薄膜生产过程中，有用单腔室的负压吸风装置；有些采用双腔室的，但是腔室内气流流通性差，内壁容易冷凝油滴，有的油滴直接滴在冷辊上，严重影响薄膜的质量。另外，现有双腔室负压吸风装置通常采用双抽风机，系统结构复杂，成本较高，能耗较高。
发明内容
本发明的目的在于克服上述已有技术的不足，提供一种流延膜生产用负压吸风装置，该装置结构简单，能耗较低，可以有效抽出生产过程中产生的气体和高温油烟，减少油烟冷凝，降低废品率。
为了实现上述目的，本发明采用的技术方案是：一种流延设备用负压吸风装置，包括吸风罩体、设置于该吸风罩体上的抽风管及与该抽风管连接的抽风装置，所述吸风罩体内设置有第一真空腔及第二真空腔，其特征在于：所述吸风罩体内内还设有一分流腔，分流腔分别与抽风管、第一真空腔及第二真空腔相连通。

进一步地，所述分流腔内还安装有两套用于调节所述第一开口、第二开口大小的调节机构，调节机构包括导向槽、风量调节板和摇杆，导向槽设有两条，分别固定在分流支架上且位于所述开口两侧，风量调节板两侧嵌套在导向槽内，在风量调节板上固定有齿条，摇杆两端通过轴承安装在所述吸风罩体上，在摇杆上安装有与所述齿条相啮合的齿轮。
进一步地，所述吸风罩体包括安装架、与该安装架可调节安装的侧向挡板、活动地设置于该侧向挡板的侧向冷辊挡板、安装板、隔热板、固定于分流腔底部的中隔板、可调节地安装在中隔板上的中间冷辊挡板及两侧密封板；所述侧向挡板、侧向冷辊挡板、中隔板、中间冷辊挡板与分流腔围设成所述第一真空腔，所述隔热板、安装板、中隔板、中间冷辊挡板与分流腔围设成第二真空腔。
