技术领域
本发明涉及物流运输领域,具体涉及一种流体排放系统以及流体排放方法。
背景技术
为了粘稠性液体储存,运输及灌装排放等,目前市场上有很多液体储运装置。
国外专利US5765723A,公开了一种密封液袋,它的主体部分是采用PVC涂塑布通过热熔焊接或高频焊接制成的密封软体容器;该密封软体容器的两端分别设置有进液阀门和出液阀门。该液体内衬本体在一般高流速,流质液体中使用效果比较好;但是在粘稠液体的排放中,液体排放慢,效率低;排放完成后液体在内衬本体中残留大,造成成本浪费。一般在排放快结束时会用螺旋缠绕挤压等外在物体让此内衬本体缠绕挤出残留的液体。
国外专利IL156984A,公开的一种密封袋液,它的主体部分是采用PVC涂塑布或PE膜,通过热熔焊接或高频焊接制成的密封软体容器;该密封软体容器的两端分别设置有进液阀门和出液阀门;主体还包括辅助排放的气袋,气袋上设置有充气的进气口。液体排放过程中,需要往辅助的气袋中充气,靠气体的挤压来排放较粘稠的液体。此方案不能根本解决液体残留问题,并且还要辅助充气,增加成本。

具体实施方式
以下将结合附图对本发明的较佳实施例进行详细说明,以便更清楚理解本发明的目的、特点和优点。应理解的是,附图所示的实施例并不是对本发明范围的限制,而只是为了说明本发明技术方案的实质精神。
术语说明
中型散装容器:复合型中型散装容器(下文称为IBC容器)是一类在国际范围内被食品、生化、医药、化工等行业广泛所使用的包装周转容器。由于IBC集装桶可以被多次重复使用,在灌装、储运和运输时具备明显的优势,并且与圆桶相比,IBC集装桶可以节约35%的储存空间,尺寸符合ISO标准,不仅适用于无菌罐装而且箱体紧凑,便于大批量安全高效存储,故而大量运用于液体、颗粒和薄片等形态物料的运输、包装、存储过程中。目前,现存规格有820L、1000L、1250L三种,通常情况下,其组成结构包含塑料内胆、灌装口、排放装置(阀门或简易排放口等)、侧板、底座及盖板。
本发明的流体排放系统通常包括容器和内衬袋,内衬袋安装于容器内并设有排放口,其中,安装该内衬袋的容器通常为中型散装容器(IBC)。本发明的流体排放系统还包括挤推装置和驱动装置,驱动装置与挤推装置连接并用于驱动挤推装置运动,其中,该挤推装置包括至少一对挤推件,例如至少两根滚轴,当需要排放内衬袋内的液体时,将两根滚轴夹持住内衬袋,在驱动装置的驱动下,该对挤推件作相对运动,例如两根滚轴做相对反向转动,对内衬袋施加挤推力,从而对内衬袋内的液体进行挤排,在液体排放过程中,随着内衬袋内液体的减少,两根滚轴在驱动装置的驱动下自动随液面下降并对液体进行挤推。本文中,挤推力指的是对力作用对象,例如内衬袋及其内容纳的液体,同时产生挤压和推动效果的力。
下面结合附图对本发明的各示例实施例进行描述。
第一实施例
下面结合图1-23对本发明的第一实施例进行描述。
图1是本实施例的流体排放系统的立体图,其中,容器的侧板处于折叠状态,图2是图1的流体排放系统的分解图,图3是本实施例的流体排放系统的挤推装置和驱动装置的立体图,其中,挤推装置和驱动装置组装在一起,图4是图3的挤推装置和驱动装置的分解图,图17示出本实施例的排放系统的立体图。
如图1-4、17所示,流体排放系统100包括容器1、设置于容器1内的内衬袋2、挤推装置3和驱动装置4,其中,挤推装置3通常至少包括两根滚轴(下文将会进一步详细描述)。在需要排放时,挤推装置3和驱动装置4可以放置于容器的内部,诸如图1所示的容器内部的侧壁上,而需要排放内衬袋内的液体时,将挤推装置3的两根滚轴夹持住内衬袋的袋体(即使得内衬袋的袋体穿入两根滚轴之间),并将驱动装置4与挤推装置3连接,从而在驱动装置4的带动下,挤推装置3的两根滚 轴向下做相对反向转动并挤压内衬袋2的袋体,从而对内衬袋内的液体进行挤排,在液体排放过程中,随着内衬袋内液体的减少,两根滚轴在驱动装置的驱动下自动随液面下降并对液体进行挤推。
下面结合图3-11对本实施例的流体排放系统100的挤推装置3和驱动装置4进行详细描述。
图5-7是本发明的挤推装置3的立体图,其示出本发明的挤推装置3从分开状态向连接状态变化的过程,图8是图7的挤推装置3的立体剖视图,图9是图8的端视图,图10是本发明的挤推装置3的另一立体剖视图,其示出齿轮啮合状态,图11是图10的端视图。
如图3-11所示,挤推装置3包括第一部分31和第二部分32,第一部分31和第二部分32的大部分结构完全相同。第一部分31包括滚轴311、齿轮312和挤推支架313。挤推支架313具有一个两端开口的空腔,滚轴311的一端安装于挤推支架313的空腔内,齿轮312环绕滚轴安装并也位于挤推支架313的空腔内。
如图5所示,在本发明中,滚轴311为长条杆状件,其沿轴向方向的尺寸远大于其沿径向方向的尺寸,且挤推支架的长度远小于滚轴311的长度,从而滚轴311只是两端的一定长度容纳于空腔内,其余中间的大部分用来与内衬袋2的袋体接触,从而挤压袋体,下文还会详细描述。
参见图4,在本实施例中,滚轴311包括弹性软体3111和支撑轴3112,弹性软体3111环绕支撑轴3112设置,具体为弹性软体3111为圆筒状,其具有与支撑轴3112的外径配合的内径的内部腔体,支撑轴3112伸入弹性软体3111的内部腔体中。例如,支撑轴3112的外表面可以进行涂胶处理,弹性软体3111包裹吸附于支撑轴3112的整个外表面,从而在驱动装置的驱动下支撑轴3112转动时弹性软体3111同步转动。应理解的是,滚轴311外包裹的弹性软体也可以是其他形状,例如椭圆形、三角形或者如图34所示的方形。图34所示的滚轴与图9所示的滚轴之间不同之处仅在于其外包裹的弹性软体3111a和3211a的横截面形状,其余相同,在此不再详述。
继续参见图4,支撑轴3111包括第一段311A、第二段311B和第三段311C,其中,第一段311A的外径小于第二段311B的外径,第二段311B的外径小于第三段311C的外径。齿轮312安装于第二段311B上,第一段311A和第二段311B皆安装于挤推支架312内,即第一段311A和第二段311B的总长度与挤推之间312的长度大致相等,其中,第一段311A的端部一体向外(在图4中为向右)伸出一驱动柱311D,驱动柱311D的外径小于第一段311A的外径,并用于与驱动装置4中的驱动槽配合,下文会进一步描述。弹性软体3111环绕第三段311C的外周设置。
参见图5,挤推支架313的外部轮廓近似半圆柱形,其包括弧面313A和平面313B,平面313B用于与第二部分的挤推支架323的平面配合。挤推支架313的设置齿轮的部分的平面设有开口313B1,开口313B1的尺寸根据实际工艺需要确定, 第一部分31的齿轮和第二部分32的齿轮通过开口313B1相互啮合。
继续参见图5,在第一部分31的挤推支架313的平面313B上设置有连接结构,在第二部分32的平面323B上设置有配合连接结构,通过连接结构和配合连接结构的配合,将第一部分31和第二部分32相互固定。在本实施例中,第一部分31的挤推支架313上的连接结构为多个连接孔31B2,这些孔的形状和尺寸可以相同也可以不同,第二部分32的挤推支架323上的配合连接结构为多个连接销(图未示),连接销的形状和尺寸分别与对应的第一部分31上的连接孔31B2的形状和尺寸配合,通过将第二部分32的连接销(图未示)插入第一部分31的连接孔31B2中从而将第一部分31和第二部分32相互固定。
虽然在本实施例中,第一部分31的挤推支架313上只设置连接孔,在第二部分32的挤推支架323上只设置连接销,然而本领域的技术人员可以理解,也可以在第二部分的挤推支架323上设置连接孔,在第一部分31的挤推支架313上设置连接销,或在第一部分31和第二部分32的挤推支架313、323同时设置连接孔或连接销,只要这些连接孔或连接销相互配合即可。
继续参照图5,第一部分31的挤推支架313上设置有锁紧机构,第二部分32的挤推支架323上设置有配合锁紧结构,通过该锁紧结构和配合锁紧结构的配合,将第一部分31和第二部分32相互锁紧。在本实施例中,锁紧结构为设置于第一部分31的挤推支架313的上表面上的锁紧钩31B3,配合锁紧机构为设置于第二部分32的挤推支架323的上表面的锁紧柱32B3,通过旋转锁紧钩31B3可以将锁紧钩31B3挂扣在锁紧柱32B3上,从而将第一部分31和第二部分32相互锁紧。
如图5-8所示,在本实施例中,挤推装置的第一部分31还包括支撑杆314,支撑杆314的两端分别连接于滚轴311两端的挤推支架313上,从而将滚轴两端的挤推支架连接在一起。
在本实施例中,驱动装置3的第二部分32的结构与第一部分31的基本相同,相同之处在此不再详细描述,请参见上述第一部分31的有关描述。
如图3-11所示,第二部分32包括滚轴321、齿轮322和挤推支架323。滚轴321包括弹性软体3211和支撑轴3212,弹性软体3211环绕支撑轴3212设置,具体为弹性软体3211为圆筒状,其具有与支撑轴3212的外径配合的内径的内部腔体,支撑轴3212伸入弹性软体3211的内部腔体中。挤推装置的第二部分32也包括支撑杆315,支撑杆315的两端分别连接于滚轴321两端的挤推支架323上,从而将滚轴321两端的挤推支架323连接在一起。
第二部分32与第一部分31不同之处在于,驱动装置3的第二部分32的挤推支架323与第一部分31的挤推支架313不同。参见上文,在本实施例中,第二部分32的挤推支架323的平面上设有多个连接销,而第一部分31的挤推支架313的平面上设有多个连接孔。然而,本领域的技术人员可以理解,也可以在第二部分的挤推支架323上设置连接孔,在第一部分31的挤推支架313上设置连接销,或在 第一部分31和第二部分32的挤推支架313、323同时设置连接孔或连接销,只要这些连接孔或连接销相互配合即可。
图12是本发明的驱动装置4的立体图,图13是本发明的驱动装置3与挤推装置4的组装立体示意图,如图12-13所示,驱动装置4包括马达41、传动箱42和组装母座43,马达41与传动箱42连接,组装母座43设置于传动箱42的侧面,在组装母座43内设有驱动件431,驱动件431的端部设有驱动槽432,驱动槽423用于与第一部分31的支撑轴311的端部的驱动柱311D或第二部分32的支撑轴321的端部的驱动柱321D配合,第一部分31的挤推支架313的一端和第二部分32的挤推支架323的一端皆容纳于组装母座43内。
图14-15示出本实施例的内衬袋2的平面示意图,如图14-15所示,内衬袋2由前片2a和后片2b密封焊接形成,在前片2a或后片2b上设有排放口21,排放口21靠近内衬袋2底部的焊线23设置。通常,在本发明中,排放口的下边缘与内衬袋的底部的焊线的距离小于或等于15cm,更佳地,小于或等于10cm。在本实施例中,排放口21焊接在后片2b上,以及在前片2a的上部还焊接有灌装口22,灌装口22用于装入液体(通常为粘度大于30万CPS的粘稠液体),排放口21用于排出液体(通常为粘度大于30万CPS的粘稠液体)。在本实施例中,内衬袋2由规则的前片2a和后片2b(例如呈矩形的前片2a和后片2b)密封焊接形成。
本实施例的内衬袋由于由前片和后片密封焊接形成,以及排放口靠近内衬袋的底部焊线设置,因此,当内衬袋内装入液体时,排放口大致位于内衬袋底部的中线(焊线)位置,即内衬袋大致关于排放口呈轴对称,从而在液体排放过程中,液体能够比较彻底地通过排放口从内衬袋内排出。
图16示出本发明的排放系统的立体图,图17-20为本发明的排放系统的剖视图,其示出本发明的排放系统的排放液体的过程,图21-23示出本发明的排放系统的剖视图,其剖面与图17-20的剖面不同。
如图16-23所示,排放内衬袋内的液体时,将挤推装置的第一部分和第二部分夹持住内衬袋,并使得第一部分上的齿轮与第二部分上的齿轮相互啮合,并通过设置在第一部分上的连接结构(例如连接孔)和设置在第二部分上的配合连接结构(例如连接销)将第一部分和第二部分相互连接,通过第一部分上的锁紧结构(例如锁紧沟31B3)和第二部分上的配合锁紧结构(例如锁紧柱32B3)将第一部分和第二部分相互锁紧,最后将驱动装置连接到挤推装置,最后启动驱动装置,通过驱动装置的驱动柱的旋转带动滚轴旋转,通过第一部分的齿轮和第二部分的齿轮相互啮合,两根滚轴做相对反向转动,从而对内衬袋内的液体进行挤排,在液体排放过程中,随着内衬袋内液体的减少,两根滚轴在驱动装置的驱动下自动随液面下降并对液体始终进行挤推。
从图16-23可以看出,整个挤推装置随着内衬袋内液面的下降自动下降,内 衬袋中的液体最后通过排放口全部排出,由于滚轴始终对内衬袋进行挤压,因此,内衬袋内的液体基本全部通过排放口排出,从而实现内衬袋内的液体的零残留排放。
虽然在上述实施例中,挤推装置和驱动装置一体形成,然而应理解的是,在另一实施例中,挤推装置内可以集成有驱动装置,其中,该驱动装置可自带电源或使用外接电源。
第二实施例
下面结合图24-31对本发明的第二实施例进行详细说明。第二实施例与第一实施例的主要区别在于,在第二实施例中,挤推装置的滚轴具有锥度,从而在挤推排放过程中,可以将内衬袋内的液体朝排放口集中,从而加快液体排放速度以及使得液体的排放更彻底。本文仅就第二实施例的流体排放系统与第一实施例的流体排放系统的区别之处进行描述,其与第一实施例相同的地方在此不再详细描述,相关内容可参见第一实施例的相关描述。
图24是本实施例的挤推装置的立体图,图25是图24的挤推装置的剖视图,图26是本实施例流体排放系统100A的俯视图,图27示出图26的挤推装置,图28图27中A部分的放大图,图29-31是本发明的流体排放系统的剖视图,其示出流体排放过程的不同阶段。
如图24-31所示,本实施例的排放系统100A包括容器1、内衬袋2、挤推装置3A和驱动装置4A。内衬袋2安装于容器1内。挤推装置3A包括至少两根滚轴31A和32A,驱动装置4A集成于挤推装置3A的端部,并用于为挤推装置3A提供动力。当需要排放内衬袋内的液体时,两根滚轴31A和32A夹持住内衬袋2,在驱动装置4A的驱动下,两根滚轴31A、32A做相对反向转动,从而对内衬袋2内的液体进行挤排,在液体排放过程中,随着内衬袋2内液体的减少,两根滚轴31A、32A在驱动装置4A的驱动下自动随液面下降并通过自身的相对转动对内衬袋2内的液体始终挤推。
如图25所示,滚轴31A包括支撑轴31A1和弹性软体31A2,弹性软体31A2环绕支撑轴31A1设置,其中,支撑轴31A1为大致圆柱状,即其外径沿轴向基本不变化,而弹性软体31A1的外径沿轴向均匀变化,从而形成具有锥度的弹性软体。
如图24-31所示,在对内衬袋2内的液体进行挤推排放的过程中,滚轴外部的弹性软体会随着内衬袋内的液体的多少以及两层内衬袋之间的部分的厚薄而进行弹性变化,从而挤在挤推过程中,弹性软体能使内衬的厚薄分布不均的状态都被弹性吸收掉,即:内衬厚的地方,弹性软体弹性变形,滚轴始终对内衬有相对的挤压力,内衬薄的地方,弹性软体同时也贴合内衬袋从而使内衬袋有相对的挤压力。这样在排放的过程中,挤推推装置夹持内衬,不管厚度如何的每个部分,始终在滚轴长度范围内受到滚轴的相对挤压力,内衬袋内的液体始终全部 被挤推装置挤推到排放口,从而实现内衬袋内的液体零残留排放。
此外,由于滚轴具有锥度,因此,在挤推排放过程中,将滚轴的较细的一端置于内衬袋的排放口所在的上方,滚轴的较粗的一端置于内衬袋的与排放口相对的另一端的上方,从而在对内衬袋内的液体进行挤推排放的过程中,滚轴的比较粗的一端由于线速度大,因此,滚动的距离比滚轴的比较细的一端的滚动的距离远,从而将内衬袋内的液体集中到内衬袋的排放口处,从而加快内衬袋内液体的排放速度,并实现内衬袋内的液体零残留。
虽然在本实施例中,弹性软体从一端向另一端均匀变化,从而形成具有相同锥度的弹性软体,然而,本领域的技术人员可以理解,每一根滚轴也可以包括两段外径均匀变化的锥度段,或每一根滚轴可以包括多段(例如三段)外径均匀变化的锥度段。
第三实施例
下面参照图32-33对本发明的第三实施例进行说明。第三实施例与第一实施例和第二实施例的区别在于内衬袋上设有导流结构。其它部分与第一实施例完全相同或与第三实施例完全相同。
图32-33分别示出本实施例的内衬袋的两个表面。如图32-33所示,本实施例的内衬袋20由前片20a和后片20b通过边缘部分相互焊接形成,排放口201设置在前片20a或后片20b上并靠近内衬袋20的底部的焊线26设置。在本实施例中,排放口201焊接在后片20b上,以及在前片20a的上部还焊接有灌装口202,灌装口202用于装入液体(通常为粘度大于30万CPS的粘稠液体),排放口201用于排出液体(通常为粘度大于30万CPS的粘稠液体)。
如图32-33所示,在本实施例中,前片20a和后片20b的底部都形成相互配合的导流结构24和25,在本实施例中,导流结构24和25都是朝向排放口201倾斜的斜面,具体斜面倾斜的角度可以根据需要设置。
虽然在本实施例中,内衬袋20的前片20a和后片20b的底部分别设置了两个倾斜面24、25,然而,本领域的技术人员可以理解,内衬袋的底部也可以形成多个倾斜面,比如三个、四个和五个,多个倾斜面彼此连接次形成,并朝排放口倾斜,从而在排放过程中,内衬袋内的液体能够沿多个倾斜面聚集至内衬袋的排放口。
排放内衬袋内的液体时,两根滚轴在驱动装置的驱动下自动随液面下降并对液体始终进行挤推,液体能够沿导流结构24和25集中流至排放口201,从而能够更彻底地将内衬袋内的液体通过排放口201排出。
在本实施例中,由于内衬袋由前片和后片密封焊接形成和排放口靠近内衬袋的底部焊线设置,以及在内衬袋地底部设置有导流结构,因此,当内衬袋内装入液体时,排放口大致位于内衬袋底部的中线(焊线)位置,即内衬袋大致 关于排放口呈轴对称,以及液体能够通过导流结构聚集至排放口,从而在液体排放过程中,液体能够比较彻底地通过排放口从内衬袋内排出。
本发明的内衬袋的导流结构可以有多种变形,只要其能够将液体沿集中流至排放口即可实现本发明的目的。本领域的技术人员应理解的是,第三实施例的内衬袋既可以用于第一实施例,也可以用于第二实施例。当其用于第二实施例时,通过导流结构与锥度滚轴的配合,可以更高效地将内衬袋内的液体集中排至排放口,并从排放口排出内衬袋。
虽然在以上实施例中,对挤推装置的挤推支架进行了详细说明,然而本领域的技术人员可以理解,其它形式的挤推支架也可以用于本发明。本发明的主要特点在于,首先,挤推装置无需悬挂,即挤推装置的两根滚轴可以随内衬袋内的液面的下降自动向下运动,从而对内衬袋内的液体始终挤推;其次,滚轴的外部包裹有弹性软体,在挤推排放过程中,滚轴的弹性软体可以随着内衬袋内的液体的增加或减少而进行弹性变化,与内衬袋保持接触,从而内衬的各个阶段都会受到挤推力,实现液体的零残留;再次,滚轴可以为锥度滚轴,从而将液体集中排至排放口并通过排放口排出内衬袋;最后,在内衬袋的底部还可以设置导流结构,从而将内衬袋内的液体集中排至排放口。应理解的是,本发明的锥度滚轴以及导流结构,都是为了实现同样的目的,即将内衬袋内的液体集中排至排放口并通过排放口排出。
此外,虽然在以上实施例中,弹性软体为一个整体并且包裹支撑轴的大部分,然而,本领域的技术人员可以理解,弹性软体也可以仅仅包裹支撑轴的一小部分,在这一定程度上也可以实现本发明的目的。以及虽然在以上实施例中,挤推装置仅仅包括两根滚轴,即挤推装置的第一部分和第二部分都仅仅包括一根滚轴,然而,本领域的技术人员可以理解,挤推装置的第一部分和第二部分也可以包括多根滚轴,例如,三根、四根、五根等,此时,多根滚轴可以相互连接形成一个整体,并与挤推装置的另一部分的滚轴配合。另外,以上实施例中,两根滚轴相对反向转动,然而,仅一根滚轴转动也可实现挤推效果。此外,两根滚轴的相对反向转动既可以是同步转动也可以是不同步转动。以及本发明的容器可以为一般容器,也可以为可折叠容器。挤推装置可为独立部件置于箱体外部,当需要排放液体时,将挤推装置和驱动装置组装好放入箱体内,也可在侧板的内壁上设置滑轨,将驱动装置安装于该滑轨上,当驱动装置与挤推装置连接好进行挤推液体过程中,驱动装置可以随着液面的下降沿着滑动轨道向下滑动。
图35示出根据本发明的又一实施例的挤推器40的结构示意图。如35所示,挤推器包括两个挤推件301和302。挤推件301和302为滚轴。挤推件301和302的第一端可转动地安装于第一安装支架303上,第二端可转动地安装于第二安装支架304上。第一安装支架303和第二安装支架304均包括两个可分离的安装头,挤推件301和302的端部分别安装在相应的安装头上。由此,挤推件 301和302可分离,从而便于夹持内衬袋的操作。这里,滚轴可以采用与上述实施例的滚轴类似的结构,在此不再详述。
第一安装支架303和第二安装支架304上还分别连接有支撑杆307和支撑杆308。转轴305的两端分别可转动地连接于支撑杆307和308。在转轴35的一端还连接有手轮306。手轮306的转动可带动转轴305转动。这里手轮及转轴305用作挤推器40的驱动装置。与上面实施例不同的是,本实施例的驱动装置用于驱动内衬袋,而不是滚轴。
图36至40示出采用了挤推器40来排放中型散装容器内的内衬袋内的液体的过程图。如图36-40所示,在排放液体时,所需使得中型散装容器1内的内衬袋2的顶部穿过两根滚轴301和302并夹持于两根滚轴301与302之间。接着,将内衬袋2的顶部缠绕于转轴305上。然后,转动手轮306。手轮306的转动带动转轴305转动。转轴305的转动将内衬袋卷绕于转轴305上,同时滚轴301和302对内衬袋(及其内的液体)施加挤压力,液体向下移动而排出。在液体排出的同时,挤推器40自动随着内衬袋内液体液位的下降而下降。如此,随着手轮306的不断转动,内衬袋不断被卷绕到转轴305上,内衬袋内的液体液位不断下降,同时挤推器40不断跟随液位的下降而下降,直至液体排放完。由于在内衬袋内液体的排放过程中,内衬袋一直受到挤压力,这种挤压力将会将附着于内衬袋内壁上的粘稠液体向下刮,由此减少了液体在内衬袋内的残留。
应指出的是,图35-40所示的挤推器40能够跟随内衬袋中液体液位的下降而下降主要是因为挤推器10相对于容器1来说是自由活动的,且挤推器与内衬袋关联。应理解的是,还可以取消转轴305与安装支架之间的支撑杆,同样可以实现上述效果。此时,挤压器的挤压装置和驱动装置的分开的。
图41是图35的挤推器的变形例。图41所示的挤推器60与图35所示的挤推器的不同之处主要在于驱动装置。图35的驱动装置为由手动,而图41的驱动装置为自动。具体地,挤推器60包括两个挤推件601和602。挤推件601和602为滚轴。挤推件601和602的第一端可转动地安装于第一安装支架603上,第二端可转动地安装于第二安装支架604上。第一安装支架603和第二安装支架604均包括两个可分离的安装头,挤推件601和602的端部分别安装在相应的安装头上。由此,挤推件601和602可分离,从而便于夹持内衬袋的操作。这里,滚轴可以采用与上述实施例的滚轴类似的结构,在此不再详述。
第一安装支架603和第二安装支架604上还分别连接有支撑杆607和支撑杆608。转轴605的两端分别可转动地连接于支撑杆607和608。在转轴35的一端还连接有马达606。马达606的转动可带动转轴605转动。这里马达及转轴用作挤推器60的驱动装置。与图35所示的实施例相同,本实施例的驱动装置也是用于驱动内衬袋,而不是滚轴。如图42所示,本实施例的挤推器60的工作过程与图35所示的实施例的工作过程基本相同,差别仅在于一个是通过手轮 手动转动,而另一个是通过马达自动转动,在此不再详述。
图43和44示出根据本发明的一实施例的挤推装置50的结构示意图,其中图43的挤推装置50处于打开状态,图44的挤推装置50处于夹持状态。图43和44的挤推装置可以与图35和41的驱动装置配合使用,在此不再详述。所示如图43和44所示,挤推装置50设有推板501和滚轴502。滚轴502的一端铰接于推板501的一端,滚轴502的另一端可拆卸地连接于推板501的另一端。具体地,滚轴502的另一端通过可拆卸的锁紧螺丝503连接于推板501的另一端。工作时,可以先松开锁紧503,将内衬袋置于推板与滚轴之间,然后再将滚轴锁紧,从而使得内衬袋夹持于推板与滚轴之间。
图45和46示出根据本发明的又一实施例的挤推装置70的结构示意图,其中图45的挤推装置70处于打开状态,图46的挤推装置70处于夹持状态。图45和46的挤推装置可以与图35和41的驱动装置配合使用,在此不再详述。所示如图45和46所示,挤推装置70设有第一推板701和第二推板702。第二推板702的一端铰接于推板701的一端,第二推板702的另一端可拆卸地连接于推板701的另一端。具体地,第二推板702的另一端通过可拆卸的锁紧螺丝703连接于推板701的另一端。工作时,可以先松开锁紧703,将内衬袋置于推板与第二推板之间,然后再将第二推板锁紧,从而使得内衬袋夹持于推板与第二推板之间。
应理解的是,在上述原理下,挤推装置还可以采用其他结构形式,在此不再一一列举。类似地,驱动装置可以是手动、气动或者电动,在此不再一一列举。
以上已详细描述了本发明的较佳实施例,但应理解到,在阅读了本发明的上述讲授内容之后,本领域技术人员可以对本发明作各种改动或修改。这些等价形式同样落于本申请所附权利要求书所限定的范围。
