本发明提供了一种抽真空系统,其包括并联的若干条支路,各支路分别与真空腔相连通,各支路上分别设有串联的多个真空泵组,真空泵组包括一个真空泵体或并联的多个真空泵体,且各真空泵组的真空泵体的数量相等或不等。基于上述结构,该抽真空系统通过各支路内的多个真空泵组同时完成对真空腔内气体的抽吸,与单一的真空泵相比能够快速完成抽吸操作,有效提升了抽真空系统的抽吸效率,减少真空包装袋的密封时间。
本发明还提供了一种真空包装机,其采用了上述的抽真空系统,因此同样具有结构设计巧妙、用户使用体验好等优点。
附图说明
图1为本发明实施例的抽真空系统的结构示意图。
图中,1、进口主路;2、第一支路;21、第一真空泵组;22、第二真空泵组;3、第二支路;31、第三真空泵组;32、第四真空泵组;4、真空泵体。
具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明,但不用来限制本发明的范围。
应当理解的是,本发明中采用术语“前”、“后”等来描述各种信息,但这些信息不应限于这些术语,这些术语仅用来将同一类型的信息彼此区别开。例如,在不脱离本发明范围的情况下“前”信息也可以被称为“后”信息,“后”信息也可以被称为“前”信息。
如图1所示,本发明提供了一种抽真空系统,其包括并联的若干条支路,各支路分别与真空腔相连通,各支路上分别设有串联的多个真空泵组,真空泵组包括一个真空泵体4或并联的多个真空泵体4,且各真空泵组的真空泵体4的数量相等或不等,也即各真空泵组的真空泵体4数量之间并不存在任何关系,真空泵体4的数量都是相互独立的。具体而言,在本发明实施例中,抽真空系统包括并联的第一支路2和第二支路3,需要注意的是,此处的第一支路2和第二支路3也即上述的若干条支路,进一步的,第一支路2上设有串联的第一真空泵组21和第二真空泵组22,第一真空泵组21包括并联的两个真空泵体4,第二真空泵组22包括一个真空泵体4,第二支路3上设有串联的第三真空泵组31和第四真空泵组32,第三真空泵组31包括并联的两个真空泵体4,第四真空泵组32包括一个真空泵体4。
基于上述结构,使用时启动抽真空系统,第一真空泵组21、第二真空泵组22、第三真空泵组31和第四真空泵组32同时运转,真空腔内的气体被抽吸并排出真空腔外,这种多支路多泵组的设计与现有的单一真空泵相比提升了抽吸速度,减少了抽吸时间,有效提升了真空包装袋的密封速度。
进一步的,在本申请的一些实施例中,第一真空泵组21位于第一支路2的上游,第二真空泵组22位于第一支路2的下游,具体的,此处的上游与下游指的是真空腔内的气体经过第一支路2排出真空腔外时的气体流向,也即真空腔内的气体经过第一支路2排出真空腔外时首先经过第一真空泵组21,随后经过第二真空泵组22,因此第一真空泵组21位于第一支路2的上游,第二真空泵组22位于第一支路2的下游。
同样的,在本申请的一些实施例中,第三真空泵组31位于第二支路3的上游,第四真空泵组32位于第二支路3的下游。此处的上游与下游指的是真空腔内的气体经过第二支路3排出真空腔外时的气体流向,也即真空腔的气体经过第二支路3排出真空腔外时首先经过第三真空泵组31,随后经过第四真空泵组32,因此第三真空泵组31位于第二支路3的上游,第四真空泵组32位于第二支路3的下游。
进一步的,在本申请的一些实施例中,该抽真空系统还包括进口主路1,进口主路1与真空腔相连通,第一支路2和第二支路3的吸气端分别与进口主路1相连通。为了完成对真空腔内气体的正常抽吸,需要在真空腔的腔壁设置连接第一支路2和第二支路3的开口,而进口主路1的设置则避免了这一情况的出现,第一支路2、第二支路3以及可能设置的更多支路通过进口主路1与真空腔相连通,真空腔内的气体经过进口主路1进入第一支路2和第二支路3,能够有效提升真空腔的结构稳定性,进口主路1的结构设计巧妙,使用方便。
与之相类似的,在本申请的一些实施例中,该抽真空系统还包括出口主路(图未示),此时,第一支路2和第二支路3的排气端分别与出口主路相连通,第一支路2和第二支路3的气体经过出口主路流出真空腔外,同样能够减少真空包装机的开口设计,提升真空包装机的结构稳定性。
综上所述,本发明提供了一种抽真空系统,其包括并联设置的第一支路和第二支路,第一支路上设有串联的第一真空泵组和第二真空 泵组,第一真空泵组包括并联的两个真空泵体,第二真空泵组包括一个真空泵体,第一真空泵组位于第一支路的上游,第二真空泵组位于第一支路的下游,第二支路上设有串联的第三真空泵组和第四真空泵组,第三真空泵组包括并联的两个真空泵体,第四真空泵组包括一个真空泵体,第三真空泵组位于第二支路的上游,第四真空泵组位于第二支路的下游。与现有技术相比,该抽真空系统通过两条支路的多个真空泵组完成对真空腔内气体的抽吸,其结构设计巧妙,抽吸速度快,减少了抽吸时间与真空包装袋的密封时间,提升了用户的使用体验。
本发明还提供了一种真空包装机,由于其具有上述的抽真空系统,因此同样具有结构设计巧妙、用户使用体验好等优点。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明技术原理的前提下,还可以做出若干改进和替换,这些改进和替换也应视为本发明的保护范围。
