Description

一种驱动装置,特别是用于喷墨打印头,具有电磁隔离
技术领域
本发明涉及一种驱动装置,特别是用于喷墨打印头的驱动装置构成了本发明的目的。
背景技术
喷墨打印头,特别是专用于瓷砖装饰的喷墨打印头包括多个促动器装置,这些促动器装置有控制各个喷嘴的打开和关闭的功能,该喷嘴将用于喷射釉料,从而能够精确控制获得合适装饰所需的釉滴的喷射。
促动器装置通常包括多个相同的螺线管,这些螺线管相互平行地并排布置在公共中间平面上。各螺线管包括同心地插入至线圈中的铁磁芯,该线圈的供电能够产生电磁场,该电磁场使得芯在至少两个极端位置之间位移。在芯的两个极端位置中,通常确定了打印头喷嘴的打开位置和关闭位置。
由螺线管产生的电磁场相互干扰,从而产生最接近螺线管的不希望感应。这将损害单个螺线管的合适控制,该螺线管将受到由最接近螺线管接收的控制信号的影响。为了减小在螺线管之间的相互干扰,必须保持在它们之间的特定距离,从而增加了促动器装置的总体尺寸。
而且,在已知的促动器装置中,将产生相当高的温度,这导致各个螺线管的性能退化。
发明内容
本发明的目的是提供一种促动器装置,特别是但并不局限为用于喷墨打印头,该促动器装置允许克服现有装置的缺点。
根据本发明的促动器装置的优点是它能够一致地减少在多个螺线管之间的相互电磁干扰。
根据本发明的促动器装置的还一优点在于它能够一致地降低单个螺线管的工作温度。
附图说明
通过下面对附图中由非限定实例表示的本发明优选实施例的详细说明,将更好地了解本发明的其它特征和优点,附图中:
图1表示了根据本发明的促动器装置的总体示意图;
图1a和1b表示了图1的促动器装置的竖直正视图的两个视图;
图2表示了沿图1b的平面A-A的剖视图;
图3表示了根据图1b的平面B-B的剖视图;
图4表示了沿图1a的C-C平面的剖视图;
图5表示了沿图1a的平面D-D的剖视图。
具体实施方式
根据本发明的促动器装置包括两个或更多个螺线管(S),各螺线管(S)包括线圈(4),各线圈(4)绕纵向轴线(X)缠绕成柱形螺旋。各线圈能够通过图2中所示的连接器(P)进行供电。
各螺线管(S)包括同心地插入相应线圈(4)中的铁磁芯(2)。优选为柱形形状的铁磁芯(2)通过由线圈(4)产生的电磁场的作用而受到趋向于使它沿纵向轴线(X)运动的力,再产生磁场。在根据本发明的促动器装置的优选实施例中,芯(2)保持静止,并利用磁场来驱动打印头喷嘴的闸板元件(未示出)运动。在其它实施例中,通过线圈(4)的控制供电作用,线圈(2)可以沿纵向轴线(X)在至少第一和第二工作位置之间运动。线圈(4)缠绕在管形线轴(3)上,芯(2)布置在线轴(3)的内部。芯(2)的纵向轴线(X)基本与线圈(4)和线轴(3)的纵向轴线(X)重合。
在促动器装置的、用于控制喷墨打印头的优选使用中,各芯(2)再利用它自身的磁场而作用在打印头喷嘴的闸板上。例如,线圈(4)的供电导致打印头喷嘴的打开状态,而线圈(4)的不供电导致它的关闭状态。
在所示实施例中,促动器装置包括沿相同中间平面(T)对齐的八个螺线管(S)。当然,螺线管(S)的数量可以变化。
螺线管(S)相互平行,即线圈(4)的纵向轴线(X)相互平行。优选是,螺线管(S)彼此相等。
螺线管(S)插入容纳体(5)中。特别是,各螺线管(S)插入在容纳体(5)内形成的相应空腔中。这些空腔在其端部处开口,以便均允许螺线管(S)插入,并允许芯(2)凸出至容纳体(5)的外部,以便控制相应的打印头闸板或其它部件的位移。
促动器装置包括用于各螺线管(S)的隔离体元件(1)。各隔离体元件(1)由磁性材料制成,并至少局部在相应螺线管(S)附近或侧部延伸。用于获得隔离体元件的合适材料的实例是坡莫合金。
对于各螺线管(S)使用隔离体元件(1)能够极大地减小在多个螺线管(S)的线圈(4)之间的干扰。这能够通过减小促动器装置的尺寸而减小在螺线管(S)之间的距离。另外,对于各螺线管(S)使用隔离体元件(1)还能够减小在两个相邻促动器装置之间的干扰,从而能够减小它们之间的距离。
在促动器装置的优选实施例中,各隔离体元件(1)包括两个平行和相对的纵向部分(11)。两个纵向部分(11)通过横向部分(12)而连接在一起。如图2中所示,各隔离体元件(1)基本为U形。隔离体元件(1)的优选结构使得对于由各螺线管(S)产生的电磁场的有益屏蔽效果最大化,从而以一致的方式来减少在螺线管(S)之间的干扰。纵向部分(11)优选是包括端部部分(13),该端部部分定向成垂直于纵向轴线(X),并终止于芯(2)附近。
优选是,各螺线管(S)布置在相应隔离体元件(1)的纵向部分(11)之间的空间中。特别是,隔离体元件(1)布置在容纳体(5)的外部。而且,隔离体元件(1)形成为使得纵向部分(11)位于离相应螺线管(S)预定距离处。该距离可以根据由螺线管(S)产生的电磁场的特性来选择,以便尽可能地减少在螺线管(S)自身之间的干扰。
优选是,各隔离体元件(1)还形成为使得相应螺线管(S)的铁磁芯(2)至少在它的一端处布置在离横向部分(12)预定距离处。这能够进一步减少在螺线管(S)之间的相互干扰。
容纳体(5)优选是提供有至少一个冷却导管(6),冷却流体能够在该冷却导管内进行流动。该冷却导管(6)形成在容纳体(5)的外部侧表面上。优选是,导管(6)至少局部由外部盖(7)来界定,该外部盖(7)与容纳体(5)的外部侧表面密封连接。也可选择,导管(6)可以整个在容纳体(5)内获得,以便与螺线管(S)重叠而不与其连通。冷却导管(6)基本在平行于中间平面(T)的两个平面之间延伸,并与这样的隔腔重叠,螺线管(S)在该隔腔中插入容纳体(5)的内部。
如图2、3、4所示,导管(6)在容纳体(5)的外部与螺线管(S)重叠。在优选实施例中,导管(6)的发展形式有相对的凸出部,具有与螺线管(S)平行的直线部分(61)。在优选实施例中,促动器装置包括两个导管(6),这两个导管(6)布置在容纳体(5)的两个相对侧表面处,在螺线管(S)的相对侧,各自由外部盖(7)来界定。优选是,两个导管(6)在它们的端部处与公共进口导管和公共出口导管连接,但是也可选择,可以提供有独立的供给出口。优选是,各隔离体元件(1)布置在外部盖(7)的外侧。
导管或冷却导管(6)的存在能够明显降低螺线管(S)的温度,使它远低于现有装置进行操作时的温度。这能够提高各螺线管(S)的性能和精度。
