一种科里奥利粉体秤主要采用齿轮传动机构,该计量秤有一个进料口和一个出料口,主要测量部件是位于进料口下部的测量盘,驱动装置是一台旁置式的减速电机,通过同步带把动力传递至位于秤体内部的齿轮箱,齿轮箱的驱动轴带动测量盘旋转,粉体从进料口流入到测量盘上,测量盘受到反向 阻力,通过安装于齿轮箱机构上的传感器检测装置能检测到主轴受到的扭矩,通过一定的算法可以将扭矩信号换算成物料的质量。
由于上述计量秤的传动装置由内置于测量秤体的齿轮箱构成,为了保证测量的精度,这个齿轮箱的加工装配要求比较高的精度,这就造成了箱体和齿轮副机构的加工装配难度大大增加,造成成本增加;同时由于其结构复杂,后期使用过程中的维护成本也很大,这样就使该设备的综合成本居高不下,不利于其推广。因此,需要一种既测量精确又经济合理的新型计量秤。
本公开的实施例提供一种科里奥利计量秤,包括驱动部分,该驱动部分包括:外壳体,内部限定容置空间;驱动电机,具有底座以及输出轴件,所述驱动电机的至少一部分设置在所述外壳体外部;电机座,固定到驱动电机的所述底座,且具有第一轴孔,且所述输出轴穿过所述第一轴孔;轴承支座,沿径向方向设置在所述电机座外侧,且具有第二轴孔,其中所述电机座、所述轴承支座设置在所述容置空间中,所述轴承支座固定到所述外壳体,所述第一轴孔和所述第二轴孔共轴,所述电机座的所述第一轴孔的侧壁与所述输出轴件之间设置有第一轴承,所述电机座的外壁与所述轴承支座的所述第二轴孔的侧壁之间设置有第二轴承。这里,应该注意的是的,电机的输出轴件包括电机的输出轴本体以及与之连接的加长部分,例如,接长轴套。第一轴承设置在所述第一轴孔的侧壁与所述输出轴件之间可以是设置在输出轴和/或接长轴套与所述第一轴孔的侧壁之间。由于输出轴和接长轴套是固定的一起的,下面的有些描述并没有刻意区分输出轴和输出轴件。由于将驱动电机的输出轴和/或其加长部分通过第一轴承与电机座配合,电机座通过第二轴承与轴承支座配合,这样相对于轴承支座而言,驱动电机和电机座整体通过第二轴承与轴承支座配合连接,驱动电机的输出轴和/或轴的加长部分与电机座之间的第一轴承在结构上变为驱动电机的内部轴承,其间的摩擦力变为内力,从而在后续测量物料质量时,不会影响使得驱动电机的输出轴和电机座反向旋转的扭矩力,使得测量精度更高,适于测量小流量物料的质量。
备选地,如果电机是输出轴本体长度足够,则电机的输出轴件可以只包括输出轴,本公开的实施例并不对此进行限制。
下面将结合附图对本公开的实施例的技术方案进行详细描述。
图1示出了本公开实施例的科里奥利计量秤的驱动部分的示例图,参见图1,该驱动部分100包括:外壳体4,所述外壳体4的内部限定容置空间 410;驱动电机1,具有底座110以及输出轴件120,该驱动电机1的至少一部分设置在所述外壳体4外部;电机座21,固定到驱动电机1的所述底座110,且具有第一轴孔210,且所述输出轴件120穿过所述第一轴孔210;轴承支座3,沿径向方向设置在所述电机座21外侧,且具有第二轴孔310,其中所述电机座21、所述轴承支座3设置在所述容置空间410中,所述轴承支座3固定到所述外壳体4,所述第一轴孔210和所述第二轴孔310共轴,所述电机座21的所述第一轴孔210的侧壁与所述输出轴件120之间设置有第一轴承31,所述电机座21的外壁与所述轴承支座3的所述第二轴孔310的侧壁之间设置有第二轴承41。
这样,驱动电机的输出轴以及输出轴上的接长轴套与电机座之间为转动配合,而电机座与轴承支座之间也是转动配合。
例如,驱动电机1可以一部分或者全部位于所述外壳体4外部。为了使得驱动电机1能够穿出,外壳体4上会开设有供驱动电极1穿出的通孔,驱动电机的底座可以通过法兰等固定到电机座,法兰可以位于外壳体的通孔处,也就是固定法兰之上的部分均在外壳体外部,驱动电机的底座的上侧表面和下侧表面之间的任意位置可以恰好与外壳体4的位于驱动电机侧的外侧表面位于同一高度处、或者其上侧表面或下侧表面与该外侧表面位于同一位置处;或者,电机座与电机底座法兰连接的径向部分的上侧表面和下侧表面之间的任意位置可以恰好与外壳体的位于驱动电机侧的外侧表面位于同一高度处,或者上侧表面或下侧表面与该外侧表面位于同一位置处,这里的上侧表面指的是朝向电机一侧的表面,下侧表面指的是背向电机一侧的表面,通过将法兰设置在外壳体的通孔处,电机座和输出轴的整体都位于外壳体内,从而可以更好地保护电机座、输出轴、轴承支座以及第一轴承和第二轴承,且还可以减小外壳体的体积,降低成本,而且在维修或更换电机时,由于法兰位于通孔处,使得操作更方便。或者,底座与电机座的固定法兰以位于外壳体内部,也就是驱动电机的除底座之外的一部分位于外壳体的通孔处。
例如,驱动电机的底座可以通过采用螺栓、螺钉、卡接等方式固定到电机座,本公开的实施例并不对此进行限制,只要能够实现将电机底座固定到电机座即可。
例如,电机座可以包括中空而带有轴孔的柱形主体部分,例如,圆柱形、 棱柱等,为了和电机的底座固定,电机座还可以包括位于主体部分的朝向驱动电机一端的径向向外延伸的周缘,从而方便固定。
例如,所述轴承支座3的主体可以为中空而带有轴孔310的柱形,例如,圆柱形、棱柱形等,为了便于将第二轴承41安装在轴承支座3与电机座21之间,该轴承支座内的第二轴孔310可以为台阶孔,例如,如图1所示,该第二轴孔310可以具有内径不同的二个部分,由驱动电机侧开始向下依次为第一部分3101和第二部分3102,且第一部分和第二部分内径依次减小,其中第二部分3102位于轴承支座的最远离所述驱动电机的一侧。
备选地,为了方便轴承的安装和定位,所述轴承支座的第二轴孔310可以具有内径不同的两个部分或者三个以上的部分,本公开的实施例并不对此进行限制,也就是,第二轴孔310至少包括内径不同的至少两个部分。
例如,所述第一轴承31包括沿着所述输出轴件120上下设置的至少两个第一子轴承311和312,所述至少两个第一轴承311和312在所述输出轴件120的延伸方向上由所述隔套313间隔,第一子轴承311的内圈的下端面可以与套接在输出轴件1200或者输出轴件1200的接长轴套上的隔挡件挡止配合或者电机座21的远离电机的端部定位;第一子轴承311的上端面,例如,内圈的上端面可以设置有隔套313,隔套313的远离第一子轴承311的一端设置有第二子轴承312,第二子轴承312的远离隔套313的外圈的上端面可以与电机座挡止配合和/或第二子轴承312的远离隔套313的内圈的上端面可以与电机的底座挡止配合,例如,可以通过驱动电机底座的台阶或者电机座的向内伸出的凸出部而定位,从而通过这样的配合而防止至少两个第一子轴承上下窜动,而仅是绕输出轴旋转。
例如,为了进一步减小输出轴或套接在输出轴上的接长轴套与电机座相对转动时的摩擦力,第一轴承31还可以包括沿轴上下设置的三个或三个以上的子轴承,为了定位,三个子轴承之间可以通过隔套、接长轴套上的台阶或凹槽或者电机座第一轴孔210的内壁上的台阶或凹槽而定位,本公开的实施例并不对此限制,只要能够实现三个子轴承的定位即可。
例如,为了便于轴承的安装和定位,电机座21的面对第二轴孔310的内壁的外壁也可以设置为具有台阶状,通过提供台阶可以为第二轴承41的安装提供定位面。
例如,所述第二轴承41包括沿着所述输出轴件上下设置的至少两个第 二子轴承411和412,第二子轴承412的下端面可以与所述轴承支座挡止配合,例如,第二子轴承412可以通过轴承支座的第二轴孔的第二部分312与第一部分311交界处的台阶而定位,第二子轴承412内圈的面对驱动电机的上端面可以与电机座挡止配合或者与电机座的外壁上的台阶档止配合,和/或外圈的上端面设置有隔套,该隔套隔开至少两个第二子轴承411和412,第一子轴承411的外圈的下端面设置有隔套,第一子轴承411可以通过轴承支座3的向内凸出的凸出部或者中间带有轴孔的挡板而定位,例如,第二子轴承411的上端面可以与该凸出部或者挡板挡止配合。
例如,在根据本公开实施例的科里奥利计量秤中,驱动部分100还可以包括:皮带轮调节件61,具有供所述轴承支座穿出的通孔611;所述外壳体4包括凸台401,在所述外壳体4的内壁上向内延伸,且位于所述皮带轮调节件611的下侧,从而所述皮带轮调节件61可以设置在所述凸台401上,该凸台401构造为支撑该皮带轮调节件61。
备选地,该凸台401可以沿着外壳体4的周向设置一圈,或者包括多个间隔设置的凸台段,多个凸台段的长度可以彼此相同也可以彼此不同,本公开的实施例并不对此限制,只要凸台能够足够地支撑该皮带轮调节件61即可。
例如,当外壳体4的截面是矩形时,该凸台411可以是矩形环。
例如,在根据本公开实施例的科里奥利计量秤中,驱动部分100还可以包括:距离调节件612,构造为将所述皮带轮调节件61连接到所述外壳体4且调节所述皮带轮调节件61到所述外壳体4的在垂直于所述驱动电机的输出轴件120方向上的距离,所述轴承支座3包括突出部314,设置在所述轴承支座3的外壁上,沿周向向外伸出且固定到所述皮带轮调节件61,所述轴承支座3固定到所述外壳体4是通过固定到皮带轮调节件61而实现的,所述突出部314可以通过螺栓、螺钉、卡接、粘接等方式固定到所述皮带轮调节件61。
例如,当轴承支座3的横截面是圆环形时,该突出部314可以为圆环形。
例如,皮带轮调节件61可以为L形板,所述L形板包括主板613和边板614,所述通孔611开设在所述主板613中,所述边板614可以垂直于所述主板,且边板614可以沿着平行于输出轴的方向延伸,且边板可以平行于外壳体设置。例如,当外壳体的横截面是矩形,边板614可以平行于其所面 对的外壳体的侧壁。
例如,距离调节件612可以包括螺栓6121,螺栓6121的一端可以穿过所述边板614上的螺孔6141,螺栓6121的另一端可以穿过所述外壳体上的螺孔,所述螺栓可以是张紧螺栓且构造为可通过旋转而调节皮带轮调节件与所述外壳体之间的在垂直于所述驱动电机的输出轴件120方向上的距离,且在调节到需要距离后,距离调节件612将皮带轮调节件61固定到外壳体4。例如,通过旋转螺栓6121,可以调节螺栓位于外壳体与边板之间的距离,从而调节皮带轮调节件与所述外壳体之间的在垂直于所述驱动电机的输出轴件120方向上的距离。
例如,外壳体在垂直于所述输出轴的方向上的截面可以是圆形、正方形或者矩形,当所述外壳体的截面是矩形时,皮带轮调节件61的主板613可以为矩形而中间开设有供轴承支座4穿过的圆形孔的矩形,边板设置在主板613的远离计量部分200的一侧边上,该边板上可以设置多个距离调节件612,例如,设置多个螺栓6121,通过以相同的幅度调节多个螺栓,从而使得调节后的边板614仍然平行于边板614所面对的外壳体的侧壁。
例如,在所述驱动部分中,输出轴件120可以包括输出轴1200和接长轴套121,该接长轴套121固设在所述输出轴1200上,例如,该接长轴套121可以通过螺栓122与输出轴1200压紧配合且通过键槽防止所述接长轴套121与输出轴1200发生相对旋转;第一带轮71,固定到接长轴套121,例如可以通过螺栓、螺钉、铆接或者卡接等固定到接长轴套121,而且第一带轮71和接长轴套121之间的配合面上还可以设置平键,而防止第一带轮71相对于接长轴套121旋转。第一带轮71上设置有同步带6,该同步带6与计量部分的第二带轮72连接,从而将驱动电机的驱动力通过同步带传递到计量部分的主轴,而主轴带动测量盘旋转而实现对进入计量部分200的物料的质量测量。
例如,可以在接长轴套121的远离电机的一侧设置有压盖5,压盖5通过螺栓122固定到接长轴套121,在安装过程中,在轴承支座3内部的第一和第二轴承已经安装好了之后,该压盖5可以对轴承支座进行定位,从而可以对轴承支座内安装的第一和第二轴承进行沿轴方向的定位,防止轴承支座内的第一和第二轴承上下窜动,例如,可以通过螺钉、铆钉、卡接等方式固定,本公开的实施例并不对此进行限制。
例如,所述外壳体4上设置有供所述同步带6穿过的通孔(图中未示出),从而所述同步带穿过所述外壳体4上的通孔而进入所述计量部分200的壳体而套设在计量部分的第二带轮72上。
这样,当将同步带6安装到所述第一带轮71时,可以调节距离调节件612使得皮带轮调节件61朝向计量部分200的方向移动,也就是,增加皮带轮调节件61的远离计量部分200的部分与外壳体4之间的在垂直于所述驱动电机的输出轴件120方向上的距离,由于轴承支座3固定到皮带轮调节件61且轴承支座3支撑电机座21以及驱动电机1,则当皮带轮调节件61移动时,会带动轴承支座4、电机座21和驱动电极1整体朝向计量部分200移动,从而可以方便地将同步带6安装到第一带轮71。而当同步带6需要调紧时,可以调节距离调节件612使得皮带轮调节件61向远离计量部分200的方向移动,也就是,增加皮带轮调节件61的远离计量部分200的部分与外壳体4之间的距离,从而张紧同步带,便于动力的稳定传输。例如,皮带轮调节件61的移动方向沿着垂直于输出轴方向的平移,从而利于移动的稳定性,且便于控制。
备选地,为了给驱动电机1的移动留出空间,外壳体4上开设的供驱动电极1穿出的通孔可以比驱动电机1的外径稍微大一些,例如比驱动电机1的外径大0.1-1%,例如,可以是0.5%、0.6%等。本公开的实施例并不对此进行限制,本领域的技术人员可以根据移动的需要等选择适当的通孔尺寸。
例如,在根据本公开实施例的科里奥利计量秤中,所述驱动部分还包括:测量触碰件81,固定在所述电机座21上,且构造为在所述电机座21带动下转动;传感器测量装置82,设置在所述外壳体4上或者固定到外壳体的部件上,且包括感测部,其中所述测量触碰件81在电机座的带动下具有与电机输出动力时的运动方向相反的运动趋势时抵接在所述传感器测量装置82的感测部821上,所述传感器测量装置82构造为检测所述测量触碰件81施加到其上的作用力且所述作用力转换为电信号。
例如,如图1和图2所示,驱动部分100还可以包括:外罩2,设置在所述外壳体4上方,与所述外壳体4形成其中容置所述测量触碰件81以及所述传感器测量装置82的空间,从而保护内部设置的测量触碰件81以及所述传感器测量装置82,其中所述电机1的至少一部分位于所述外罩2外部。
例如,测量触碰件81和传感器测量装置82的感测部821可以设置为位 于垂直于输出轴件120同一平面上,也就是,如果驱动部分平行于地面设置,二者设置在同一高度处,或者,可以根据测量触碰件81和传感器测量装置82的感测部在平行于输出轴方向上的厚度而高度稍微有偏差,只要能够保证测量触碰件81在电机或电机座的带动下旋转时能够抵接到传感器测量装置82的感测部821即可。
备选地,测量触碰件81可以是推杆、挡板等刚性件,测量触碰件81可以是直线形状,也可以是弯曲形状,只要能够使得测量触碰件81能够抵接到传感器测量装置82的感测部821即可。
例如,在垂直于输出轴的平面上,当从驱动电机侧观察时测量触碰件81可以设置在感测部821的逆时针方向或者顺时针方向上。从驱动电机侧观察,当驱动电机1的输出轴件120正常输出动力以驱动计量部分200的测量盘旋转时,输出轴件120的旋转方向在垂直于输出轴的平面上是顺时针方向时,感测部821相对于测量触碰件81设置在其顺时针方向上,从而当输出轴件120受到反向扭矩而电机座会产生正向,也就是顺时针方向的运动趋势,从而测量触碰件81也有顺时针方向的运动趋势,由于其顺时针方向的感测部821的阻挡而感测部821受到测量触碰件81施加的作用力,而是根据该作用力可以得到物料质量。
备选地,如图2所示,当从驱动电机侧观察时,当驱动电机1的输出轴件120正常输出动力以驱动计量部分200的测量盘旋转时,输出轴件120的旋转方向在垂直于输出轴的平面上是逆时针方向时,感测部821相对于测量触碰件81可以设置在逆时针方向上,从而当输出轴件120受到反向扭矩而电机座会产生逆时针方向的运动趋势,从而测量触碰件81也有逆时针方向的运动趋势,由于其逆时针方向的感测部821的阻挡而感测部821受到测量触碰件81施加的作用力,根据该作用力可以得到物料质量。当从轴承支座侧观察时,可以参照以上,这里将不再赘述。从而,当开机后,驱动电机转动,通过同步带驱动计量部分200的主轴而带动上部的测量盘旋转,粉体物料从进料口落到测量盘上,会对旋转的测量盘叶片产生一个科里奥利力,这样会有一个反向的扭矩作用在主轴上,再通过同步带传递到电机输出轴上从而传递到电机座上,电机座会有反向旋转的运动趋势,从而带动电机座上的测量触碰件81推动感测部,传感器测量装置82就会检测到这个扭矩,进而测算出物料的质量。

例如,为了便于对安装或者对密封空间913进行更好地密封,在主轴座的远离测量盘的一侧还可以设置盖板916,该盖板916固定到主轴座91,例如,通过铆接、螺钉、螺栓、卡接等固定到主轴座9。这样,可以在第三轴承51、间隔不同轴承的套筒等部件安装之后,在主轴座的远离测量盘的一侧加装盖板。
例如,第三轴承51可以包括沿着主轴设置的至少两个第三子轴承,所述至少两个第三子轴承之间通过套筒隔开,该套筒可以通过主轴9上的台阶例如轴肩定位而隔开至少两个第三子轴承。为了示例的方便,图3中示出了 两个第三子轴承511和512,第三子轴承511的上端面可以通过压盖912定位和/或通过主轴9上的台阶定位和/或通过另外设置的止挡板而定位,本公开的实施例并不对此进行限制。例如,第三子轴承511的内圈的上端面与主轴9的台阶挡止配合,外圈的上端面可以与主轴座或者止挡板挡止配合;外圈的下端面可以与主轴座和/或套筒挡止配合,例如外圈的下端面与主轴座挡止配合,其余下端面与套筒挡止配合。第三子轴承512的上端面可以与主轴座和/或套筒挡止配合,例如,外圈的上端面可以与主轴座挡止配合和/或其余上端面或者内圈的上端面可以与套筒挡止配合;下端面可以与止挡板和/或主轴座和/或盖板挡止配合,例如,下端面可以与主轴座的凸出部的朝向密闭空间的侧面挡止配合和/或与盖板挡止配合和/或另外设置的止挡板配合。这样,第三轴承51便可以被定位在密闭空间913中,通过挡止配合而防止第三轴承上下窜动。
例如,为了安装方便,主轴座91可以包括两个套接而固定到一起的第一部分915和第二部分916,第二部分916可以在第一部分915沿着径向方向的外侧,而管件914要穿过第一部分和第二部分二者而开口到主轴座内部的容置主轴的密闭空间。第一部分915和第二部分916通过螺钉、螺栓、卡接等彼此固定,例如第一部分915上可以设置卡槽,第二部分916可以设置卡扣,通过卡接而实现二者的固定,和/或可以通过螺钉、螺栓实现固定配合。压盖912和盖板916可以固定到第一部分915和第二部分916二者,例如通过螺钉、螺栓、卡接等实现固定。
这里,需要说明的是,为了避免物料粉末等进入主轴座而污染其内部的轴承,不同部件的接合面处可以设置有密封件,例如,弹性胶带、胶圈、毛毡垫等,例如,保护壳体30和壳体18的接合面处可以设置有毛毡垫,盖板和压盖与主轴座的接合面处也可以设置有毛毡垫。
例如,如图3所示,计量部分200还可以包括:第二带轮容置部720,其上开设有供所述同步带6穿过的带孔;带轮盖板721,设置在所述第二带轮容置部720的背向所述进料件20的一侧,使得所述第二带轮容置部720、所述带轮盖板721、所述主轴座91的位于所述测量盘14的相反侧端面和盖板916共同构成容置所述第二带轮的空间。
例如,带轮盖板721通过螺钉、卡接、铆接等固定到第二带轮容置部720,第二带轮容置部720通过螺钉、卡接、铆接等固定到所述主轴座91。
例如,在根据本公开实施例的计量部分中,如图4所示,测量盘14可以包括:轮盘141,其中设置有供所述主轴穿过的轴孔142;端环143,设置在所述轮盘141的朝向所述进料件20的一侧;多个叶片144,沿着所述测量盘14的周向设置在所述轮盘141与所述端环143之间。
例如,计量部分200还可以包括:导料构件145,固连到所述主轴9的顶端,且设置在所述轮盘141的轴孔142的中心轴线位置处,且延伸设置在所述进料件与所述测量盘的边界与所述轮盘之间。

例如,导料构件145也可以是一体的导料锥,其中形成有主轴可以插入的槽,主轴的顶端和导料锥尖端部开设有螺孔,螺栓可以穿入而主轴和导料锥两者而固定主轴和导料锥。导料锥底部和测量盘的轮盘固定到一起,且导料锥或轮盘通过张紧套固定到主轴。
例如,主轴、测量盘、导料锥、主轴座、进料口、出料口可以是中心对称的,且可以共轴设置,也就是,主轴的轴线可以穿过测量盘的中心、进料口和出料口的中心,从而在能够平稳运行,提高测量精度,更利于测量小流量物料。
例如,为了防止物料对同步带6的运转产生影响,计量部分还可以包括容置同步带6的空心筒,在计量部分中,该空心筒的一端与第二带轮容置部连通,另一端与壳体的外部连通,从而将位于第二带轮上的同步带通过空心 筒引出,而安装到第一带轮上。
例如,计量部分200的壳体18可以包括至少两个彼此固定连接的子壳体,例如,可以包括上部子壳体181和下部子壳体7,上部子壳体181的下端和下部子壳体7的上端均设置有翻沿,通过翻沿上穿装螺栓而将二者固定到一起,上部子壳体181和下部子壳体7之间密封配合,接合面处可以设置有密封件,例如,毛毡垫、橡胶垫、弹性胶带、胶圈等。
备选地,壳体18还可以包括中间壳体,设置在上部子壳体和下部子壳体之间,上端和上部子壳体,下端与下部子壳体密封配合。本领域的技术人员可以根据需要选择适当的子壳体数量。
例如,进料件20可以分为两个部分,上部是由进料口朝向物料行进方向渐细的锥形部分,下部部分可以呈柱形,从而有利于物料的进入。进料件20的上端可以具有翻沿,与保护壳体30的上端的翻沿通过螺栓而固定到一起,进料件的下端外壁可以设置固连件与保护壳体30固定到一起,保护壳体30的下端具有长的翻边,通过该翻边固连到上部子壳体181,且固连处均设置有用于密封的毛毡垫。
例如,计量部分200中,壳体18的远离所述进料口的一端设置有出料口8,例如可以是下部子壳体7的未固连到上部子壳体181的一端形成有开口而作为出料口8,或者可以是另外设置的部件而固设到下部子壳体7而形成出料口8,该部件可以在沿着物料的行进方向呈渐细的锥形,从而利于物料流出,该部件的上端和下部子壳体7的下端可以形成有翻沿,通过穿过该翻沿的螺钉而实现二者固连,且二者接合面处设置有密封件,例如毛毡垫等。
例如,下部子壳体7可以在物料的行进方向上呈现渐细的锥形,下部子壳体7和上部子壳体181的接合处的高度可以略低于测量盘的所处的位置,这样物料从测量盘的侧面被甩出后,将进入下部子壳体7所围设的空间中,这样为了利于物料的流出,下部子壳体7也可以设置为呈现在物料行进方向上渐细的锥形,例如,上部子壳体181可以呈现直筒形,本领域的技术可以根据需要而为壳体和壳体的各个部分选择合适的形状,本公开的实施例并不对此进行限制。
例如,根据本公开实施例的科里奥利计量秤还可以包括:控制系统300,包括:处理器301,信号连接到所述传感器测量装置82,构造为根据所述传感器测量装置82通过作用力转换而成的电信号计算得到所述待测量物料的 质量;存储器302,存储有指令,当所述处理器301执行所述指令时执行以上动作,而且存储有所述待测量物料的质量数据。
例如,该处理器301还可以构造为控制驱动电机旋转,而驱动测量盘转动。备选地,该控制系统300可以设置在驱动部分100的外壳体内部或者外罩内部,或者可以单独设置在外部而对驱动部分100进行控制。本公开的实施例并不对此进行限制,本领域的技术人员可以根据需要而进行设定。
例如,图5示出了包括驱动部分和计量部分的科里奥利计量秤的示例性截面示意图,如图5所示,驱动部分和计量部分可以通过螺钉、螺栓等固连到一起,例如,驱动部分的外壳体和/或外罩可以和计量部分的壳体固连到一起,例如通过螺钉、卡扣等固连到一起。为了稳固地支撑包括驱动部分和计量部分的科里奥利计量秤整体,还可以设置支腿,例如可以设置至少四个支腿12。
例如,计量部分200的管件914还可以从壳体18穿过且穿过支腿12上方设置的横向管道而通向外部,而在横向管道和管件的远离计量部分200的一端设置接头或油杯等。
例如,如图5所示,驱动部分100的外壳体4和外罩2通过螺钉与计量部分200的壳体18固连到一起,驱动部分100的外壳体的靠近计量部分200的一侧可以固定连接到支腿12上方的而其中设置从计量部分200的壳体穿过的管件的外壳体上,而在此处,驱动部分100和计量部分200可以共用一条支腿12,在其上方,驱动部分的外罩2可以通过翻沿固连到计量部分200的壳体18。
下面将结合附图5对根据本公开实施例的科里奥利计量秤的工作过程进行示例性地描述:科里奥利计量秤启动后,驱动电机1的输出轴1200和接长轴套121转动,带动固定到输出轴1200和接长轴套121的第一带轮71转动,从而通过同步带6驱动计量部分200的第二带轮72转动,进而驱动主轴9转动,带动上部的测量盘14旋转。粉体从进料口201进入秤体,从上部落到导料锥1451上,再分流到测量盘上,由于惯性作用,相对静止的粉体会对旋转的测量盘叶片产生一个反向的科里奥利力,这样会有一个反向的扭矩作用在主轴9上,通过同步带6的连接作用,驱动电机的输出轴件120也会受到反向的扭矩,由于电机座在径向上是自由转动的,这样,电机座就会产生正向旋转的运动趋势,带动固定在电机座上的测量触碰件对传感器测 量装置产生一个推力,传感器测量装置就会检测到这个推力,并把这个推力信号转换为电信号,并传输到控制系统300,控制系统的处理器通过一定的算法进而测算出物料的质量。
本公开实施例提供的科里奥利计量秤的计量部分中,测量盘位于进料口的正下方,内置于计量部分中的主轴带动测量盘旋转,主轴设置在主轴座中,主轴座中采用了上下设置的至少两个轴承,从而采用轴承支撑代替了复杂的齿轮箱结构,相比于零部件众多、加工装配的精度和难度高、需要定期更换润滑油的齿轮箱结构,而本申请采用的轴承件结构简单,零部件数量少,有较好的密封和润滑条件,生产装配的难度就大大降低,不仅简单实用,且制造成本和后期维护检修成本也会降低。而且传感器测量装置和驱动部分旁置与计量仓外侧,进一步降低了装配的难度,易于维修和更换,节约了维护成本。
本公开实施例提供的科里奥利计量秤的驱动部分中,电机座在径向方向上设置在驱动电机的输出轴件(输出轴和/或接长轴套)外侧,轴承支座在径向方向上设置在电机座外侧,而驱动电机的和/或其接长轴套通过第一轴承与电机座配合,电机座通过第二轴承与轴承支座配合,这样相对于轴承支座而言,驱动电机和电机座整体通过第二轴承与轴承支座配合连接,驱动电机的输出轴和/或轴的加长部分与电机座之间的第一轴承在结构上变为驱动电机的内部轴承,其间的摩擦力变为内力,从而在后续测量物料质量时,不会影响使得驱动电机的输出轴和电机座反向旋转的扭矩力,使得测量精度更好,适于测量小流量物料的质量。
进一步地,在计量部分中,在进料件处设置有通过压缩空气的连接管,从而在物料进入时,通过连接管可以通入压缩空气,进一步地可以通过导流件通入压缩空气,从而压缩空气可以被引导到所述进料件与测量盘的接缝处,可以避免物料从该接缝处溢出,而且能够避免物料在测量盘的进口处产生局部紊乱,使得物料更快流出,提高测量精度。
进一步地,在计量部分中,在主轴座的周向设置有管件,该管件之一可以为注油嘴,由于本申请中轴承采用多道密封,并通入压缩空气,主轴座内的密闭空间有一定的正压可以防止轴承进灰,当轴承润滑时,采用常规方法无法将润滑油打进去,反而内部的润滑油有可能被压出来,该管件可以为空气置换式注油嘴,加润滑油时将密封盖打开,将主轴座内部空间中的空气导 出,通过注油嘴将润滑油注入,再将密封盖压紧,就可完成加油工作,从而利于设备维护,提升测量精度。
进一步地,本公开实施例的科里奥利计量秤采用电机作为动力,并没有包括减速电机,这样便减少了传动环节,降低了系统摩擦力。而且由于减速机齿轮箱是浸油润滑方式,润滑油对齿轮有阻力,并且是变化的,这个阻力对测量力有影响,对测量精度不利,避免采用减速机便消除了减速箱齿轮箱对测量精度的影响,进一步提升了测量精度,且更有利于对小流量物料质量的测量。
进一步地,通过采用将电机座和输出轴件之间的轴承变为电机内部轴承、驱动部分置于计量部分外部、避免采用减速电机等措施,本公开的实施例的科里奥利计量秤整体结构更加牢固,能够承受1MPa的压力。
本公开的实施例还提供一种采用如上所述的科里奥利计量秤的计量方法,如图6所示,包括如下步骤:
S100,驱动电机的输出轴件旋转,从而带动所述测量盘旋转;
S200,使得待测量的物料从所述进料口进入所述计量部分;
S300,通过传感器测量装置测量测量触碰件施加到其上的作用力;
S400,利用所述作用力计算得到所述待测量物料的质量。
例如,在所述使得待测量的物料从所述进料口进入所述计量部分的同时,该计量方法还包括:通过所述连接管通入压缩空气。
例如,该计量方法还可以包括:向所述主轴座的密闭空间中加注润滑油,包括:通过空气置换式注油嘴导出所述密闭空间中的压缩空气;利用该空气置换式注油嘴向所述密闭空间中注入所述润滑油。
例如,利用所述作用力计算得到所述待测量物料的质量可以包括:将所述作用力转换为电信号,利用所述电信号计算得到所述待测量物料的质量。
本公开的实施例的计量方法,通过采用如上任意所述的科里奥利计量秤,能够提升测量精度,且能够测量小流量的物料质量,因此,应用范围更广泛。
还有以下几点需要说明:
(1)本公开实施例附图只涉及到与本公开实施例涉及到的结构,其他结构可参考通常设计。
(2)为了清晰起见,在用于描述本公开的实施例的附图中,层或区域的 厚度被放大或缩小,即这些附图并非按照实际的比例绘制。可以理解,当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时,该元件可以“直接”位于另一元件“上”或“下”或者可以存在中间元件。
(3)在不冲突的情况下,本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上所述,仅为本公开的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以权利要求的保护范围为准。
