Description

螺旋给料装置
技术领域
本实用新型涉及工业计量技术领域，更具体地涉及一种螺旋给料装置。
背景技术
工业计量控制行业中，自动称重设备是一种常用的计量设备。现有的自动称重设备主要包括给料装置、计量装置及控制装置。其中，给料装置用于将物料输送到计量装置中，计量装置安装有传感器，传感器可将重量信号返回给控制装置，控制装置进而控制给料装置的给料速度，例如分为快速给料、中速给料及慢速给料三种不同速度，使得给料装置在不同阶段以不同给料速度进行输送，当到达预定值之后，给料装置停止给料。此时，在给料装置中，料槽的出料口会有物料由于惯性及重力作用而自然滑落到计量装置中，影响计量精度。在进行上述称重控制时，当然是希望大多数时间在快速给料阶段，这样可以缩短总体的定量时间，提高效率。然而，由于给料速度越快滑落物料的偏差越大，造成在由快速给料到中速给料，中速给料到慢速给料的切换控制点不容易控制，所以一般只能通过缩小快速给料的物料重量（减小快速给料的时间）而增加中速给料及慢速给料的时间来提高控制精度。
例如在超市中常见的定量包装的面粉，一般都是由螺旋给料装置进行传送并通过上述方式完成称重后进行包装。在称重过程中，通常希望所需传送的面粉全部由快速给料来完成，这样整体时间较短，但是速度过快的话停止时面粉滑落会造成计量精度较差。因此通常是尽可能用快速给料方式完成较多物料的给料，剩下的部分用慢速给料来完成，这时，快速给料的停止点就十分重要，如果每次快速给料结束时，输送的重量相差不大，那么就能更好地去调整设备，使其大多数的物料都由快速给料来完成，并可以更好地判断慢给料结束时由于重力等原因造成的物料滑落的重量，从而提高整体的精度与速度。
鉴于此，有必要提供一种可改善物料滑落问题的给料装置以解决上述技术问题。
实用新型内容
本实用新型所要解决的技术问题是提供一种可改善物料滑落问题的螺旋给料装置。
为了解决上述问题，本实用新型提供一种螺旋给料装置，用于自动称重设备中，所述螺旋给料装置包括筒体、设于筒体上方且与筒体相连通的料斗、设于筒体内的螺旋体、用于驱动所述螺旋体旋转的电机，所述筒体的一端为出料口，所述出料口处设有分流机构，所述分流机构包括至少一隔板而将所述出料口分隔为至少两个出料通口。
优选地，所述分流机构包括多个隔板，所述多个隔板相互连接成多个出料通口。
优选地，所述多个出料通口呈网格状或蜂窝状。
优选地，所述螺旋体包括中间轴及叶片，所述叶片在中间轴上成螺旋状分布，所述中间轴通过联轴器与所述电机的转动轴相连。
与现有技术相比，本实用新型所提供的螺旋给料装置由于在出料口设置分流机构而将出料口分隔为多个出料通口，为物料的惯性滑落增加阻力，从而可减少物料滑落的重量，减小每次滑落的物料的重量变化，因此，更容易控制快速给料、中速给料及慢速给料三种不同给料速度的转换，可以更大程度地利用快速给料，从而缩短时间，提高效率，而由于更容易控制物料滑落的重量，可明显提高整个自动称重设备的计量精度。
通过以下的描述并结合附图，本实用新型将变得更加清晰，这些附图用于解释本实用新型的实施例。

具体实施方式
下面将结合本实用新型实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，附图中类似的组件标号代表类似的组件。显然，以下将描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
本实用新型所提供的螺旋给料装置可用于自动称重设备中，其受控于自动称重设备的控制装置，在控制装置的控制下可为计量装置输送预设重量的物料。
参照图1至图3，其展示了本实用新型螺旋给料装置的第一实施例。本实施例的螺旋给料装置10包括截面为圆形的筒体110、设于筒体110上方且与筒体110相连通的料斗120、设于筒体110内的螺旋体130、用于驱动所述螺旋体130旋转的电机140。其中，螺旋体130包括中间轴131及叶片132，所述叶片132在中间轴131上成螺旋状分布，所述中间轴131通过联轴器（置于图中壳体150之内）与电机140的转动轴相连，在电机140的驱动下，螺旋体130在筒体110内进行旋转，使得物料可在筒体110内以图1中的箭头D所示的方向进行传输，也即从筒体110的进料侧往其出料侧输送。料斗120设置在筒体110的进料侧的上方以向筒体110内输送物料，而筒体110的出料侧的末端为出料口，出料口的下方设有计量装置以接收螺旋给料装置10所输送的物料。
本实用新型的螺旋给料装置10还包括分流机构160，该分流机构160设于筒体110的出料口处，该分流机构160包括至少一隔板而将所述出料口分隔为至少两个出料通口，从而为物料的惯性滑落增加阻力。在某些实施例中，例如本实施例中，所述分流机构160包括两横隔板161、162，两横隔板161、162上下平行设置，每个横隔板161、162的两端均固定在筒体110的内壁，从而两横隔板161、162将出料口分隔为上、中、下三层分布的多个出料通口，此外，该分流机构160还设有纵隔板163，该纵隔板163连接两横隔板161、162且向下延伸并固定在筒体110的内壁，该纵隔板163用于更好地支撑两横隔板161、162且同时将出料口进一步分隔为更多的出料通口。
参照图4，其展示了本实用新型的第二实施例。本实施例与第一实施例的区别仅在于：本实施例的分流机构仅包括一横隔板261，该横隔板261与筒体210固定在筒体210的内壁，从而将出料口分隔为上、下两出料通口。
参照图5，其展示了本实用新型的第三实施例。本实施例与第二实施例的主要区别仅在于：本实施例的分流机构除了包括横隔板361外还包括交错设置的多个倾斜隔板362，该横隔板361和多个倾斜隔板362共同将筒体310的出料口分隔为多个出料通口，多个出料通口呈网格状分布。可理解地，根据具体给料需求，在其它实施例中也可将分流机构设计为蜂窝状分布的多个出料通口或其它可缓冲物料滑落的结构。
如上所述，本实用新型所提供的螺旋给料装置由于在出料口设置分流机构而将出料口分隔为多个出料通口，为物料的惯性滑落增加阻力，从而可减少物料滑落的重量，减小每次滑落的物料的重量变化，因此，更容易控制快速给料、中速给料及慢速给料三种不同给料速度的转换，可以更大程度地利用快速给料，从而缩短时间，提高效率，而由于更容易控制物料滑落的重量，可明显提高整个自动称重设备的计量精度。
以上结合最佳实施例对本实用新型进行了描述，但本实用新型并不局限于以上揭示的实施例，而应当涵盖各种根据本实用新型的本质进行的修改、等效组合。
