进一步的在涂布装置的基础上， 本实用新型进一步提供一种涂布装 置， 具体参照附图 3及附图 4, 包括挤压头 1、 过渡辊 3、 基材 2和烘干 箱 4, 所述基材 2跨设在过渡辊 3上并由过渡辊 3沿基材 2传动方向经 过挤压头 1和烘干箱 4, 挤压头 1的头部朝向基材 2, 所述挤压头 1包 括挤压头下唇 11和挤压头上唇 12,沿基材 2传动方向挤压头上唇 12设 置在前端， 挤压头上唇 12与挤压头下唇 11之间设置有供浆料通过的通 道 13, 所述挤压头还设置有腔体 14, 腔体 14从外界通入浆料并与通道 13相通， 挤压头下唇 11的头部高于挤压头上唇 12的头部， 挤压头下唇 11的头部为圓角 111。
涂布装置在运行时， 挤压头下唇 11 的圓弧表面近似的充当涂布辊 的表面， 实现了可以直接将浆料涂覆与悬空的基材 2上， 基材 2的单面 涂覆或者双面涂覆都可以采用该设备；
当基材 2采用双面涂覆时， 具体实施例中， 所述挤压头为两个， 分 别设置在基材 2的上方和下方。
本实施例中， 过渡辊 3为两个， 两个过渡辊的轴线平行排列， 基材 2跨设在两个过渡辊 3上， 之后再传至烘干箱 4, 挤压头 1的朝向与基 材 2垂直。
参照附图 3-附图 5 , 在双面涂布的基础上， 为了防止液态浆料因箔 材弯曲、 漂浮发生流动影响涂布厚度的均匀性， 必须采用托辊承托， 由 于其两面的浆料都处于液态， 具有一定的流延性， 因此传统的烘干箱 4 不能在传动的同时进行烘干， 本实施例中的烘干箱 4包括箱体 41及设 置在箱体 41内的压辊组件，压辊组件相对应的设置在箱体 41内的两侧， 压辊组件包括对应设置的上压辊 42及下压辊 43 ,所述上压辊 42与下压 辊 43由动力装置驱动转动， 所述上压辊 42与所述下压辊 43之间设有 由于夹持基材 2侧边的空白部 21的间隙。
基材 2在涂布时， 基材 2的浆料涂覆在其上， 基材 2的两侧边缘留 出一定宽度的空白部 21 ,采用一定宽度的上压辊 42与下压辊 43夹住基 材 2的空白部 21 , 因此， 上压辊 42与下压辊 43不会触碰到涂覆区域， 因此在传动的过程中不会破坏到涂布浆料， 使双面同时涂布的基材 2也 能实现承托烘干。
本实施例中， 上压辊 42与下压辊 43为多个， 并排设置在箱体 41 内，并由动力装置通过皮带驱动，带传动可以保证每个压辊的速度一样， 当然， 在其他实施例中， 可以采用链传动或者齿轮传动等。
在运行的过程中， 可能会出现需要调节速度的情况， 为了满足该使 用情况， 所述动力装置为伺服电机， 依靠伺服系统来调节脉沖， 进而调 节伺服电机的运作， 其他实施例中， 动力装置为步进电机或变频交流电 机。 本实施例中， 所述过渡辊 3的材质为金属。
通过上述涂布装置， 实现了在一个涂布周期内同时涂覆双面， 单层 的烘箱即可同时烘干双面， 节约能耗 50%以上， 并节约了更换物料的时 间， 提高设备效率， 解决了在传统的涂布装置中不能实现正反面同时涂 布的技术瓶颈， 解决了涂布领域内渴望解决在结构紧凑的基础上实现双 面涂布的技术难题。
以上所述仅为本实用新型的实施例， 并非因此限制本实用新型的专 利范围， 凡是利用本实用新型说明书及附图内容所作的等效结构变换， 或直接或间接运用在其他相关的技术领域， 均同理包括在本实用新型的 专利保护范围内。
