Description

一种整粒轮及整粒机构 技术领域
本发明涉及制药技术领域，特别涉及一种整粒轮及整粒机构。
背景技术
在制药领域当中，干法制粒是制备药粒的一种重要方式。干法制粒过程是将混合好的粉料用真空上料机输送至料斗内，或用提升机加料，再通过水平螺杆送料至挤压室，经过一对垂直分布的压轮，将粉料压制成片，再经过破碎、整粒机构制成颗粒。最后真空出料至振动筛，筛分出合格颗粒。细粉回收，重新压制。
其中，整粒机构一般包括整粒轮及布置在整粒轮外围的筛网，整粒轮上设有整粒刀刃，整粒机构的工作原理为：高速旋转的整粒刀刃对落入整粒轮和筛网之间的结团或不均匀的颗粒进行作业，以最终经筛网的网孔排出均匀的颗粒。
现有技术当中，目前使用的整粒轮大都采用6-8片整粒刀刃，整粒刀刃之间间距较宽，属于宽距大刀面，主要以挤压破碎的方式进行整粒，这种整粒轮整粒效率低，且一次性收粒率低。
发明内容
基于此，本发明的目的是提供一种整粒轮及整粒机构，以解决现有技术当中整粒效率低的技术问题。
根据本发明实施例当中的一种整粒轮，包括轮体及设于所述轮体的轮面上的若干刀刃，所述若干刀刃沿所述轮体的周向均匀分布，且相邻两个所述刀刃相互衔接，所述轮体的中心部位上设有安装孔，所述整粒轮的轮面上设有若干缓冲凹陷，所述若干缓冲凹陷沿所述整粒轮的周向均匀分布，所述缓冲凹陷分布在所述刀刃上。
进一步地，每一所述缓冲凹陷分布在相邻的多个所述刀刃上。
进一步地，所述缓冲凹陷的宽度及深度均由中心往两侧逐渐减少。
进一步地，所述缓冲凹陷的最大宽度小于等于所述刀刃的长度的一半，所述缓冲凹陷的最大深度小于等于所述刀刃的高度。
进一步地，所述若干刀刃均朝所述整粒轮的旋转方向倾斜布置，相邻两个所述刀刃之间通过圆弧光滑过渡连接。
进一步地，所述缓冲凹陷位于所述整粒轮轮面的中心部位上。
进一步地，所述轮体的两端面均向内凹陷形成凹槽，所述安装孔开设于所述凹槽底部且连通两个所述凹槽。
进一步地，所述刀刃与所述轮体的中轴交叉设置。

与现有技术相比：通过将各个刀刃相互衔接布置，缩小刀刃之间的间距，增加了整粒过程中刀刃对颗粒的切削作用，减少挤压作用，提高整粒效率和收粒率。此外，在刀刃间距变窄的情况下，通过在整粒轮的轮面上设置若干缓冲凹陷，该缓冲凹陷可以暂时容纳不能及时切削成粒的物料，避免物料堆积而形成堵塞。

如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的若干实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容更加透彻全面。
需要说明的是，当元件被称为“固设于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1至图2，所示为本发明第一实施例中的整粒轮10，包括轮体11及设于轮体11的轮面上的若干刀刃12，其中：
若干刀刃12沿轮体11的周向均匀分布，且相邻两个刀刃12相互衔接，即刀刃12之间相互紧靠布置，以降低刀刃间距。刀刃12与轮体11的中轴交叉设置，并且若干刀刃12均朝整粒轮10的旋转方向倾斜布置，使若干刀刃12呈螺旋方式设置于轮体11的轮面上，形成螺旋刀刃，提高整粒时的切削作用。在具体实施时，刀刃12与轮体11的中轴之间的夹角可以为2-5°，本实施例优选为3°，刀刃12朝整粒轮10的旋转方向的倾斜角度可以为40-45°，本实施例优选为45°。
在本发明一些可选实施例当中，相邻两个刀刃12之间的间距可以小于等于一个刀刃12的宽度，优选为两者相等。在具体实施时，刀刃12的数量优选为30-40个，但刀刃12的数量实际不受限制，可以根据轮体11的外径大小而做适当调整，例如轮体11的外径变小时，可减少刀刃12的数量，反之轮体11的外径变大时，可增大刀刃12的数量。或者刀刃12的数量也可以保持不变，通过 缩小或增大刀刃12的宽度来适应轮体11外径的变化。
另一方面，整粒轮10的轮面上设有若干缓冲凹陷13，若干缓冲凹陷13沿整粒轮10的周向均匀分布，缓冲凹陷13分布在刀刃12上，且每一缓冲凹陷13分布在相邻的多个刀刃12上，在本实施例当中，每一缓冲凹陷13分布在相邻的三个刀刃12上。在本实施例当中缓冲凹陷13的数量为六个，但在具体实施时，缓冲凹陷13的数量不受限制，可以根据刀刃12的数量来进行调整，例如，刀刃12数量可以为缓冲凹陷13数量的K倍，例如K为6，刀刃12数量为36个，则缓冲凹陷13数量为6个。
为了在保证刀刃12的切削效果的前提下，最大程度提升缓冲凹陷13的容纳量，优选地，缓冲凹陷13位于整粒轮11轮面的中心部位上，缓冲凹陷13的宽度及深度均由中心往两侧逐渐减少，缓冲凹陷的最大宽度小于等于所述刀刃的长度的一半，所述缓冲凹陷的最大深度小于等于所述刀刃的高度。另外，缓冲凹陷13的宽度及深度往两侧减少的幅度可以相等，使缓冲凹陷13两侧的宽度及深度相等，或者缓冲凹陷13的宽度及深度往两侧减少的幅度也可以不相等，使缓冲凹陷13一侧的宽度及深度大于另一侧的宽度及深度。
为了保证刀刃12之间不易粘附物料，相邻两个刀刃12之间通过圆弧光滑过渡连接，使刀刃12之间不存在狭缝，物料不易残留在刀刃12之间。此外，为了保证缓冲凹陷13内不易粘附物料，缓冲凹陷13设置为内凹的弧面。
进一步地，轮体11的中心部位上设有安装孔111，以通过安装孔111来固定安装轮体11(如与电机轴连接)。具体地，轮体11的两端面均向内凹陷形成凹槽112，安装孔111开设于凹槽112底部且连通两个凹槽112，凹槽112便于安装轮体11。
在具体实施时，整粒轮10可以由整块不锈钢材料(如316不锈钢材料)雕刻而成，方便清洗、拆卸，无死角。
综上，本发明上述实施例当中的整粒轮10，通过将各个刀刃12相互衔接布置，缩小刀刃12之间的间距，增加了整粒过程中刀刃对颗粒的切削作用，减少挤压作用，提高整粒效率和收粒率。此外，在刀刃间距变窄的情况下，通过在整粒轮10的轮面上设置若干缓冲凹陷13，当物料经破碎后，落料不能做到绝对 连续，整粒轮也不能完全做到一次性切削成粒的情况下，该缓冲凹陷13可以暂时容纳不能及时切削成粒的物料，避免物料堆积而形成堵塞和挤压，进一步提高收粒率。其中，缓冲凹陷13中的物料会随着刀刃12的流线方向带出，并完成制粒。
本发明另一方面还提出一种整粒机构，请参阅图3，所示为本发明第二实施例当中的整粒机构，包括整粒轮10、布置在整粒轮10外围的整粒网20、以及驱动整粒轮10旋转的动力装置(图未示出)，其中，所示整粒轮10为上述任一实施例当中的整粒轮10，整粒网20整体呈U形结构，整粒网20顶部设有进料开口21，待制粒的物料经进料开口21掉入整粒网20内，动力装置驱动整粒轮10高速旋转，使物料进入整粒轮10与整粒网20之间的缝隙中，并在整粒轮10的刀刃12的切削作用下，完成制粒，最终经整粒网20的网孔排出均匀的颗粒。
综上，本发明上述实施例当中的整粒机构，其将整粒轮的各个刀刃相互衔接布置，缩小刀刃之间的间距，增加了整粒过程中刀刃对颗粒的切削作用，减少挤压作用，提高整粒效率和收粒率。此外，在刀刃间距变窄的情况下，通过在整粒轮的轮面上设置若干缓冲凹陷，当物料经破碎后，落料不能做到绝对连续，整粒轮也不能完全做到一次性切削成粒的情况下，该缓冲凹陷13可以暂时容纳不能及时切削成粒的物料，避免物料堆积而形成堵塞和挤压，进一步提高收粒率。其中，缓冲凹陷会随着刀刃流线方向带出，并完成制粒。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
