[0002] 目前， 工业喷绘机被广泛应用在瓷砖、 玻璃、 木材、 织物等加工产业上， 通过 喷绘的方式将釉料喷绘至瓷砖的砖胚或玻璃上， 然后再进行烧制， 烧制后釉料 颜色和质感即会变化成色。 现有的工业喷绘机可应用于任意材质的平面全彩打 印， 其颠覆性的数码打印理念给瓷砖、 玻璃的加工行业带来一股新风， 以势不 可挡的席卷了整个行业， 为客户大幅度的降低生产成本， 提高生产效率创造了 良好的条件可代替丝印、 移印、 转印设备， 无需制版、 无需套色即可制作出比 传统方式更高的印刷质量， 且机器操作简单方便、 性能稳定， 完全满足行业批 量生产要求。 再有， 喷绘机的应用同吋也大大减少加工过程中产生的粉尘， 育 够降低该过程的有害物质对操作工人身体的损害， 并能进一步降低该工业污染 的程度， 因此目前该项技术广受行业的推崇。
[0003] 工业生产使用喷绘机的墨路系统结构复杂， 且所用颜料较为特殊， 一般是采用 有机溶剂将特殊颜料进行溶解， 颜料在有机溶剂中呈悬浮态， 因此喷绘机经过 长吋间使用， 不仅喷头容易被干的热熔颜料或污物阻塞， 或喷头周围容易积集 了颜料或灰尘， 或在喷头内形成了气泡， 喷头托盘面板也会粘附、 积聚颜料液 滴， 这样的废液长吋间积聚， 不仅会减损喷头的喷绘精度和喷头使用寿命， 而 且还会影响喷绘的效果， 甚至对机器本身造成一定的腐蚀损害， 因此必须为这 种工业使用的大型喷绘机提供一种合适的喷头及喷头托盘定期清理装置， 以保 证其较好的长期使用状态。

[0006] 本专利的吸附机构单元是针对单个喷绘单元进行设计的， 由刮板、 吸附头、 容 置腔和导管组成， 所述刮板优选为软质薄片状， 与喷头托盘紧密接触， 通过吸 附机构单元相对喷头托盘进行来回移动， 随即带动刮板对喷头间隔位面板进行 刮动， 从而将其上的悬挂液滴刮落到所述容置腔的上侧面， 当该刮落的液滴积 攒到一定量， 即可被所述吸附头吸附进所述容置腔中进行收集清理； 另一方面 ， 所述吸附头经过喷头吋， 即可将喷头中多余的颜料或污物吸附清理， 再将废 液导向所述容置腔， 当容置腔收集的废液达到一定量吋， 即可通过所述导管进 行排放清理， 从而完成整个喷头及喷头间隔位面板的清理过程。
[0007] 上述方案中， 所述刮板设有 2至 4个齿状结构， 以对应喷头的间隔位面板， 从而 使所述刮板避幵喷头， 与喷头间隔位的面板充分接触， 刮动清理悬挂液滴的效 果更全面、 彻底。
[0008] 上述方案中， 所述刮板的齿状结构与吸附头相错排布， 因此进一步地， 所述吸 附头对应所述齿状结构的数量设置 1至 3个。
[0009] 所述刮板与吸附头分别对应清理喷头的间隔位面板与喷头， 因此作错幵排布的 设计更有利于两者分工、 各司其职， 从而达到最优的清理效果。 此外， 还能根 据喷绘单元设置的喷头数量来对应设计刮板齿状结构、 吸附头的数量， 使刮动 清理与吸附清理分别和喷头的间隔位面板和喷头一一对应， 针对性更强。
[0010] 上述方案中， 所述吸附头向喷头方向突起。 由于喷头多为内凹式设计， 因此相 应地吸附头作突起式设计， 有利于对喷头进行更充分的吸附清理。
[0011] 本专利继而采用上述方案中的吸附机构单元连接而成的整体吸附机构， 并且还 包括汇总管， 所述多个机构单元分别通过各自的导管接入所述汇总管， 沿所述 汇总管依次排列， 所述汇总管跨设于喷车架下侧， 用于汇总各个机构单元的废 液并将废液排放至回收槽。
[0012] 所述吸附单元通过所述汇总管而依次连接， 并且一个吸附单元对应一个喷绘单 元， 从而连结形成一整体的吸附机构， 安装在喷绘单元托盘的下方， 当汇总管 带动其上的吸附单元一同在喷车架下侧的平面上来回移动吋， 即可实现对所有 喷头及喷头间隔位面板的清理， 更为简单便捷。
[0013] 上述方案中， 所述汇总管一端连有负压源， 用于为所述吸附头提供吸附负压。
由于所有吸附单元的导管均与汇总管相连， 因此只要再汇总管的一端设置负压 源， 即可同吋使多个吸附单元的吸附头产生负压吸附的效果， 一方面以较少的 装置即实现并保证吸附清理的整体性， 简化零部件的安装、 修补； 另一方面以 负压吸附的方式进行喷头的清理， 有助于提高清理的效率与彻底性。
[0014] 上述方案中， 本专利还包括移动装置， 所述移动装置安装于喷车架的下侧、 与 所述汇总管相连， 用于带动汇总管在喷车架下侧的平面上来回移动。 在所述移 动装置的驱动下， 汇总管能在喷车架下侧的平面上实现自动来回移动， 从而使 用者可通过控制移动装置的启动来控制本专利的清理进程， 提高本专利的自动 化程度。
[0015] 上述方案中， 所述移动装置包括电机、 动轮组和皮带， 所述皮带经绕所述动轮 组， 所述电机与动轮组相连， 用于驱动动轮组带动所述皮带传动， 所述汇总管 固定于所述皮带。 优选地， 所述移动装置为皮带牵引的动轮式移动装置， 该装 置的机械组件较简单， 无论是额外安装还是维护更换， 都更加方便使用者。

发明的有益效果
有益效果 [0017] 本专利通过汇总管将多个吸附单元连结起来组成一整体吸附机构， 对喷头和托 盘实现一次性、 自动化清理， 且单个吸附单元的局部维护较方便操作。 再有， 每个吸附单元上的吸附头和刮板分别有针对性地吸附清理喷头和扫刮清理喷头 间隔位的面板， 达到细致、 彻底的清理效果。 清理后的废液进一步通过每个吸 附单元的导管排入汇总管， 从而实现统一的排放或回收。 此外， 本专利通过增 加负压源、 皮带-动轮组移动装置等， 进一步提高清理效率以及自动化清理的 程度， 有利于工业化生产应用。 本专利可针对不同的喷绘单元或喷头数量设置 不同的吸附头和刮板排布、 以及设置数量不同的吸附单元， 具有针对性强、 清 理效果好、 装卸简单、 维护方便、 自动化程度高等优点。
