具体实施方式
为了能够更清楚地描述本发明的技术内容，下面结合具体实施例来进行进一步的描述。
本发明提供了一种用于阀板计量机的计量控制系统，所述的阀板计量机包括具有出料口2的料斗1，所述的料斗的下方设置有带称重装置的物料收集器，所述的料斗的出料口设置有阀板3，所述的阀板与气缸6相连接，所述的气缸6设置有电磁阀，所述的电磁阀设置成控制所述的气缸从而带动所述的阀板相对于出料口具有第一位置A、第二位置B和第三位置C。
在一种较佳地实施方式中，所述的气缸设置有第一磁环限位装置4和第二磁环限位装置5所述的电磁阀通过所述的第一磁环限位装置和第二磁环限位装置实现控制所述的气缸从而带动所述的阀板相对于出料口具有第一位置、第二位置和第三位置。
在一种较佳地实施方式中，所述的计量控制系统设置有计时器，所述的电磁阀通过所述的计时器实现控制所述的气缸从而带动所述的阀板相对于出料口具有第一位置、第二位置和 第三位置。
在一种较佳地实施方式中，所述的阀板的第一位置为阀板处于全开状态的位置，所述的阀板的第二位置为阀板处于部分关闭状态的位置，所述的阀板的第三位置为阀板处于全关闭状态的位置。
本发明提供了一种用于阀板计量机的计量控制方法，其主要特点是，所述的计量控制方法包括步骤：
(1)根据设定的计量总值和第一重量阈值，所述的电磁阀控制所述的气缸，使得所述的阀板计量机的阀板处于全开状态，直至由所述的阀板计量机的称重结构获得的实时测量值为所述的重量阈值，进入步骤(2)；
(2)所述的电磁阀控制所述的气缸从而带动所述的阀板使得所述的阀板计量机的阀板处于部分关闭状态，直至由所述的阀板计量机的称重结构获得的实时测量值为计量总值与落差值之间的差值时，进入步骤(3)；
(3)所述的电磁阀控制所述的气缸从而带动所述的阀板使得所述的阀板计量机的阀板处于全关闭状态，且结束计量过程。
在一种较佳地实施方式中，所述的计量方法具体包括步骤：
(1)根据设定的计量总值和第一重量阈值，所述的电磁阀通过所述的第一磁环限位装置和第二磁环限位装置控制所述的气缸，使得所述的阀板计量机的阀板处于全开状态，直至由所述的阀板计量机的称重结构获得的实时测量值为所述的重量阈值，进入步骤(2)；
(2)所述的电磁阀控制所述的气缸的第一磁环限位装置和第二磁环限位装置从而带动所述的阀板，使得所述的阀板计量机的阀板处于部分关闭状态，直至由所述的阀板计量机的称重结构获得的实时测量值为计量总值与落差值之间的差值时，进入步骤(3)；

在单次计量时，需要进行大、小计量的配合使用，即粗计量和精计量的配合。大计量满足计量能力，小计量+落差实现计量精度。在上述实施方式中，小计量的控制可以通过2个磁环限位、三位中泄式电磁阀和秤共通达成，但也可以通过时间等方法控制。其中，时间控制为：控制大计量(全开)a秒，小计量(部分关闭)b秒后阀板关闭，a、b可以根据测试得到理论值，相当于磁环限位的位置转换为时间。
在一种较佳地实施方式中，所述的步骤(1)中：所述的电磁阀控制所述的第一磁环限位 装置和第二磁环限位装置，以关闭所述的第一磁环限位装置和关闭所述的第二磁环限位装置，使得所述的阀板计量机的阀板处于全开状态；

在一种较佳地实施方式中，所述的步骤(2)中：所述的阀板计量机的阀板处于部分关闭状态的程度为可调整的。
在一种较佳地实施方式中，所述的电磁阀为三位电磁阀，例如三位中泄式电磁阀。
本发明提供的计量方法对小计量方式进行改进，使阀板停在小计量位置进行精确计量，以此避免阀板机构的频繁动作。
传统计量机同一计量组件在单次计量量较大的场合下，往往需要进行大、小计量的配合使用，大计量满足计量能力，小计量+落差实现计量精度。
如图1所示，A为计量阀板全开状态，用于大计量，优先满足计量能力，精度差；B为计量阀板部分关闭状态，用于小计量，优先满足计量精度，能力小，称重结构获得的实时测量时至预设定量前值时，A→B，并保持一段时间以替代气缸频繁开闭；C为计量阀板关闭瞬间，B→C过程中的落料量+C时刻还未反映到秤上的材料重量为"落差"，精度由此时的达成。
当限位1由ON→OFF，限位2由OFF→ON→OFF时，计量阀板为A状态；
当秤上反映的值到达预设定量前值时，计量阀板开始关闭；
当限位2再次由OFF→ON时，电磁阀两个线圈同时失电，并使计量阀板停在当前位置(B状态)；
当秤上反映的值到达“计量值-落差”时，计量阀板开始关闭，直至C状态。
采用了本发明的用于阀板计量机的计量控制方法，能延长气缸和阀板机构寿命；阀板处于部分关闭状态的程度可以通过调整第二磁环限位装置的测量位置进行任意调整，应对各种材料；在阀板计量结构中加入大、小计量，兼顾了计量精度和能力。
在此说明书中，本发明已参照其特定的实施例作了描述。但是，很显然仍可以作出各种修改和变换而不背离本发明的精神和范围。因此，说明书和附图应被认为是说明性的而非限制性的。
