Description

梳理机的道夫清洁装置 技术领域
本发明属于无纺织机械技术领域，具体涉及一种梳理机的道夫清洁装置。
背景技术
上面提及的梳理机是整个无纺织产品生产系统中的一个不可或缺的组成部分，因为无纺织产品如无纺布、无纺毡等需依次经开松机开松、梳理机梳理、铺网机铺网和针刺机针刺(也可由水刺机水刺)。
在公开的中国专利文献中可大量见诸与梳理机相关的技术信息，略以例举的如CN202671748U(无纺高速杂乱输出梳理机)、CN202671744U(非织造高速杂乱梳理机)、CN115648582A(一种无纺织纤维的梳理设备)、CN104312788A(一种梳理混纺织物的高性能纤维梳理机及其梳理方法)、CN1313660C(以纤维垫的形式多路喂给纤维的盖板梳理机)和CN2816061Y(全固定盖板梳棉机)，等等。
梳理机在工作过程中，作为主锡林的主梳棉辊与作为上道夫的上出棉辊以及作为下道夫的下出棉辊之间各有三角区，具体而言，主锡林与上道夫之间区域称上三角区，而主锡林与下道夫之间的区域称下三角区。由于无法消除的前述三角区的存在会出现气旋效应(即气流旋涡效应)，气旋会影响出棉效果和出棉效率，于是通常采用挡风辊或挡风板来解决这种技术问题，如CN200958134Y(梳理机的梳理装置)和CN206089904U(梳理机)是通过设置挡风辊来缓解气流的；又如CN202466005U(非织造布梳理机)是通过设置挡风板来缓解气流的，即阻止气旋现象。此外，由本申请人提出的授权公告号为CN106222812B推荐的“高速梳理机”利用上、下三角区气流化解机构能有效地消除三角区域的气流旋涡，对于减少梳理环、降低CV值以及提高后续工序的铺网质量均具有积极意义。
但是，由于前述的上、下道夫的表面分别缠覆(即包覆)有针布，因而在工作过程中，上、下道夫的表面的针布内被包括短纤维在内的纤维杂屑缠堵填嵌，那么对于上道夫而言，由于其位于上方，因而定期或不定期清理相对容易，但是对于下道夫而言，由于位于梳理机的下方，因而清理工作是十分麻烦的，必须在拆除相关的部件后才得以清理，于是一方面会因停机时间冗长而影响生产效率，另一方面会增大设备管护人员的工作强度。还有，如果不能依需对下道夫实施良好的清洁，那么，由于包覆在下道夫表面的针布内嵌入了纤维杂屑(包括短纤维)，因而由下道夫转移出的纤维难以满足工艺所要求的程度，例如因纤维减少而影响产品的克重。再有一种情形是：当在纤维转移的过程中，如果将本来缠堵填嵌在针布内的杂屑一下子带出，那么同样会影响后续工序如铺网机铺网效果并且最终同样会影响产品质量，甚至使产品成为瑕疵产品。因此如何使下道夫基本上得以始终保持在 良好的清洁状态，长期以来成了业界关注的并且期望解决的技术问题，下面将要介绍的技术方案便是在这种背景下产生的。
发明内容
本发明的任务在于提供一种有助于避免纤维杂屑缠堵填嵌下道夫的表面的针布内而得以使下道夫始终保持于理想的清洁状态并且无需停机清理而得以确保梳理效率以及减轻设备管理人员对设备的管护作业强度的梳理机的道夫清洁装置。

继续见图1，在前述左支承墙板11上并且在对应于前述的一组调节块挡条连接座固定螺钉511的位置开设有数量与一组调节块挡条连接座固定螺钉511的数量相同的墙板螺钉孔112，一组调节块挡条连接座固定螺钉511旋入该组墙板螺钉孔112内。
由于前述的右负压发生机构43的结构是与前述左负压发生机构42相同的，因而申请人在下面仅对该左负压发生机构42作详细说明。该左负压发生机构42包括一底座421、一负压风机驱动电机422和一负压风机423，底座421在使用状态下直接支承在地坪上或者通过底座支架间接支承在地坪上(本实施例选择前者)，负压风机驱动电机422与负压风机423传动连接并且该负压风机驱动电机422以及负压风机423支承在底座421上，负压风机423具有一负压风机进气接口4231和一负压风机出气接口4232，前述下道夫针布吸尘管4的左端通过前述左连接管路与负压风机进气接口4231配接，而在负压风机出气接口4232上配接有一纤维尘屑引出管，该纤维尘屑引出管的末端既可以与纤维尘屑处理管道连接，也可以配设有滤尘袋，本实施例选择前者。
在梳理机处于工作状态下，结构及作用机理完全相同的左、右负压发生机构42、43 俱处于工作状态，下面仅以左负压发生机构42为例进行说明，在下道夫3工作状态下，其表面包覆的下道夫针布31内会缠堵以及填嵌(嵌入)纤维尘屑，于是在负压风机驱动电机422的工作下带动负压风机423，位于或称进入于下道夫针布31内的前述纤维尘屑会在下道夫针布吸尘管4的左端与负压风机进气接口4231之间的上面已提及的左连接管路引入负压风机423并从负压风机出气接口4232经纤维尘屑引出管引至尘屑处理管道或滤尘袋(本实施例采用滤尘袋)。
继续见图1，前述下挡风板32的横截面形状呈△形(即呈“三角形”)，并且在该下挡风板32对应于前述下道夫针布吸尘管4的位置构成有一朝着背离下道夫针布吸尘管4的方向凹陷的下挡风板吸尘管弧形配合腔322，前述下道夫针布吸尘管4在对应于下挡风板吸尘管弧形配合腔322的位置与下挡风板32焊接固定。
在本实施例中，前述吸尘管进尘槽41与前述下道夫针布31之间的间隙设置为1.5-5.5mm，具体是通过对结构相同并且作用机理一致的前述吸尘管左、右调节机构5、6的同步调节来满足1.5-5.5mm这一范围的调节要求的，因为随着梳理机的工作速度、无纺织纤维的原料等的变化需要按工艺要求相应改变上、下道夫2、3等的速度，同时依需改变吸尘管进尘槽41与下道夫针布31之间的间隙。以前述的吸尘管左调节机构5为例，如果要使前述调节块53向前位移(微调)，那么通过对一对调节块后调节螺钉5141的调节而使调节块53向前位移，同时一对调节块前调节螺钉521也相应向前旋动，反之亦然，实现改变下挡风板32的偏转角度；向上旋调节块上调节螺钉5121，同时相应向上旋调节块下调节螺钉5131，那么调节块53带动下挡风板32连同下道夫针布吸尘管4向上位移，反之亦然，实现前述间隙在1.5-5.5mm范围内的调节。
请参见图2，在图2中还示出了棉网输入辊7a、胸锡林7b、胸锡林剥棉辊7c、胸锡林工和辊7d、转移辊7e、前挡风板7m、主锡林剥棉辊7f、主锡林工作辊7g、一组上道夫纤维转移辊7h、一组下道夫纤维转移辊7i、上出网帘7j和下出网帘7k，由于前述这些部件的配置、功用等都属于已有技术，例如可参见申请人在上面的背景技术栏中提及的专利文献特别是CN206089904U，因而申请人不再展开说明。
综上所述，本发明提供的技术方案弥补了已有技术中的缺憾，顺利地完成了发明任务，如实地兑现了申请人在上面的技术效果栏中载述的技术效果。
