Description

一种三辊逆向涂布装置
技术领域
本实用新型涉及一种涂布装置,尤其涉及的是一种三辊逆向涂布装置。
背景技术
溶剂型树脂由于其具有非常强的挥发性,在涂布的过程中将近80%的溶剂会挥发掉,而且溶剂在挥发的同时还伴随有大量的有毒物质一起挥发到空气中。所以从环保和成本节约的角度出发,人们都更青睐于用水性树脂进行涂布生产。但是,由于水性树脂的流平性相对溶剂型树脂要差,所以现有的同向涂布装置用水性树脂进行涂布,其涂布均匀度不够,涂布效果通常都达不到要求。现有的同向涂布装置的结构如图1所示,包括胶辊1、网纹辊2、树脂槽3、电机(图中未示出)和刮刀(图中未示出),网纹辊2设置在树脂槽3的上方,胶辊1设置在网纹辊2的上方,网纹辊2由电机带动,刮刀设置在网纹辊2的上料侧,胶辊1由网纹辊2带动。涂布时,将膜4穿在网纹辊2和胶辊1之间,调整胶辊1和网纹辊2之间的距离使两者之间产生紧压力,由转动的胶辊1和网纹辊2带动膜4移动,网纹辊2直接从树脂槽3中上料并对膜4进行涂布。由于膜4和网纹辊2的运动方向相同,所以树脂相当于是网纹辊2直接粘贴到膜4上面的,由于水性树脂的流平性差等原因,这种现有的同向涂布装置的涂层不均匀,另外,其胶辊1是直接将膜4压在网纹辊2上的,会进一步导致涂层外观差,明显有涂布痕。
因此,现有技术还有待于改进和发展。
实用新型内容
本实用新型的目的在于提供一种三辊逆向涂布装置,以解决上述现有技术中同向涂布装置在使用水性树脂涂布时效果不佳的技术问题。
本实用新型的技术方案如下:
一种三辊逆向涂布装置,包括钢压辊、胶辊、网纹辊、树脂槽、电机和刮刀,所述网纹辊设置在树脂槽的上方且网纹辊的下部浸入树脂槽中,所述胶辊紧贴设置在网纹辊的上方,所述钢压辊紧贴设置在胶辊的上方,所述网纹辊与电机电联接,所述刮刀设置在网纹辊的上料侧。
所述的三辊逆向涂布装置,其中,所述网纹辊下部浸入树脂槽中的深度30毫米。
所述的三辊逆向涂布装置,其中,还包括一个控制树脂槽升降的升降装置,所述升降装置与树脂槽连接。
所述的三辊逆向涂布装置,其中,所述网纹辊的截面直径为120毫米,所述胶辊和钢压辊的截面直径为100毫米。
本实用新型通过利用网纹辊和胶辊进行一次树脂传导,由网纹辊从树脂槽中上料,再将树脂传导至胶辊上,由胶辊对膜进行涂布。另外,胶辊的转动方向与膜的移动方向相反,胶辊对膜进行逆向涂布。这种逆向涂布有剪切树脂流动的作用,涂层非常均匀,而且这种逆向涂布装置的钢压辊不直接将膜压在网纹辊上,有利于消除网纹辊留下的涂布痕。
附图说明
图1是现有涂布装置的结构示意图。
图2是本实用新型中三辊逆向涂布装置结构示意图。
具体实施方式
为使本实用新型的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本实用新型进一步详细说明。
本实施例提供一种三辊逆向涂布装置,如图2本实用新型中三辊逆向涂布装置结构示意图所示,该三辊逆向涂布装置包括钢压辊5、胶辊6、网纹辊7、树脂槽8、电机(图中未示出)、刮刀(图中未示出)和升降装置(图中未示出)。网纹辊7设置在树脂槽8的上方,网纹辊7的下部约网纹辊7的截面直径的1/4的深度浸入到树脂槽8中。胶辊6紧贴设置在网纹辊7的上方,钢压辊5紧贴设置在胶辊6的上方。网纹辊7由电机带动。刮刀设置在网纹辊7的上料侧。升降装置与树脂槽8连接,控制树脂槽的升降。在本实施例中,网纹辊7的截面直径为120毫米,胶辊6和钢压辊5的截面直径为100毫米。
当进行逆向涂布时,将膜9穿在胶辊6和钢压辊5之间。网纹辊7由电机带动旋转,胶辊6从随网纹辊7而转动,网纹辊7从树脂槽8中上料,网纹辊7上的树脂传导至胶辊6上。膜9由牵引装置带动移动,钢压辊5从随膜9而转动。膜9 的移动方向与胶辊6 的转动方向相反,胶辊6对膜9进行涂布。
由上述实施例可以看出,在该三辊逆向涂布装置中由胶辊6对膜9进行逆向涂布,这种逆向涂布的方式有剪切树脂流动的作用,树脂可以均匀的涂覆到膜9上去,其所得涂层非常均匀美观。另外,该三辊逆向涂布装置中树脂槽8中的树脂经网纹辊7传导至胶辊6上在进行涂布,膜9不与网纹辊7直接接触,有利于消除涂布痕。
应当理解的是,本实用新型的应用不限于上述的举例,对本领域普通技术人员来说,可以根据上述说明加以改进或变换,所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
