Description

卧式圆网转移印花装置 技术领域
本公开涉及一种用于纺织工业的印染机械，尤其是涉及一种卧式圆网转移印花装置。
背景技术
圆网印花机是在1963年由荷兰斯托克公司首创，虽然其历史不长，但却发展迅速。圆网印花机具有劳动强度低、生产效率高、对织物适应性强的优点。圆网印花机适合于对化纤织物、针织物、轻薄织物进行印花，在此能获得花型活泼、色泽鲜艳的效果，并且可避免传色的疵病。因此，近二三十年来，圆网印花机成为纺织品印花的主流印染机械，在我国印花生产中得到广泛应用。我国自1973年引进圆网印花机以来，逐步用其取代了原先的滚筒印花机，这也因为采用圆网印花机而使生产效率提高、成本降低、操作劳动强度减小，从而深受印花企业的欢迎，国产圆网印花机也获得了长足的技术进步。但圆网印花机受圆网结构的限制，印制精细线条时效果还不十分理想。而在众多印花技术和装置中，如圆网印花、平网印花、辊筒印花、台板印花、转移印花、数码喷墨印花，其中转移印花以其印花精细度高、层次感强且适合于大批量生产而受到关注，并且近年来发展迅速。早期的转移印花主要采用热转移印花工艺，即先将某种染料印在纸等其他材料上，然后再用热压等方式使花纹转移到织物上的一种印花方法。近年来，除了热转移印花外，冷转移印花发展迅速。冷转移印花是采用水性色浆将花型图案印刷到涂层纸上，在室温下转印到织物上，再通过冷堆或蒸化发色，最后水洗去除浮色，从而完成整个印花过程的一种印花工艺。转移印花具有仿数码的印花品质、可大批量生产并且成本远低于数码印花，因此市场前景广阔，但转印纸张的消耗成为其绿色化生产的障碍。
在目前转移印花领域，无论是热转移印花还是冷转移印花，绝大多数采用的是凹版作为版辊进行印刷，以体现其线条精细的特性，而将圆网应用于转移印花领域并商品化生产的实践此前也有企业进行了尝试，例如专利号为CN99812635.7《转印法中所用图案载体，以及为获得该载体以非晶形糖浆于涂布纸材的分散液中的应用》所公开的技术方案中，实施例1、3、4都采用了Stock RT印染机，其用圆网印刷转移至印花纸，之后再进行转印。但是其仅仅是将用于印花的圆网印花机来印刷纸张，只是采用 了圆网相对凹版而言上墨量较大的优点，而在印花精细度上却逊色于凹版。

根据本公开的实施例，所提供的卧式圆网转移印花装置整体上参见图1所示。该卧式圆网转移印花装置包括机架，在所述机架上水平布置至少两套圆网转印组件(亦称印花色组单元)3。根据印花套色或叠色需求例如可在机架长度范围内安装多套圆网转印组件3，优选安装8套圆网转印组件3。在这些圆网转印组件3之间分别安装有烘燥装置16，所述烘燥装置16为红外线烘燥装置或热风烘燥装置，优选红外烘燥装置。圆网转印组件3和烘燥装置16位于导带7的上侧。
导带7为环形导带，因此其可以在卧式圆网转移印花装置中循环移动。导带7与完成印花的织物分离之后经由导带传动装置5传动而首先经过位于导带传动装置5下游的导带清洗装置4，该导带清洗装置4用于对印制过程中可能透过织物而留在导带7上的墨水进行清洗，优选为喷水清洗装置，喷水清洗装置下游设置有毛刷。在导带 清洗装置4下游相继设置第一传送辊17、第二传送辊18、第三传送辊19以及转向辊20，其中，第一传送辊17和第二传送辊18的顶端与导带传动装置5的底端基本上位于同一水平面上(在实践中，位于不同水平面上也是可行的)，而第三传送辊19的顶端与转向辊20的底端基本上位于同一水平面上(在实践中，位于不同水平面上也是可行的)。经由三个传送辊17、18和19将导带7继续向前传送，其中，在第二传送辊18和第三传送辊19之间设置有导带纠偏装置6，经由该导带纠偏装置6将导带张紧并精确定位。在第三传送辊19和转向辊20之间设置有用于为导带上胶的导带上胶装置2，上胶之后的导带容易与待印花的织物贴合并在印花过程中不易与织物松脱。织物在经由导带上胶装置2上胶之后经由转向辊20转向，然后导带7进入贴合装置21中与待印花的织物面状地贴合在一起，之后引导织物进入圆网转印组件3和烘燥装置16中进行印花。在印花完成之后，将完成印花的织物和导带7分离，并通过导带引导装置5再次将导带传送至导带清洗装置4进行清洗，以重新开始下一个循环。
待印花的织物经由进布装置1进入贴合装置21与导带7贴合。离开圆网转印组件3的完成印花的织物与导带7分离之后，进入后续固色水洗等工序环节。
接下来参照图2详细描述图1中的圆网转印组件3之一。圆网转印组件3固定在支架外框11内，并且支架外框11通过螺栓固定在卧式圆网转移印花装置的机架上。所述圆网转印组件3还包括圆网版辊(亦称圆网印版)10、刮刀、转印辊(亦称转移辊)14、支架升降气缸12、圆网转印组件施压气缸15、刮刀组件调节机构、调节机构施压装置。
所述圆网版辊10、转印辊14和背压辊13的两端分别通过一个支撑轴(未示出)支撑在支架外框11中，其中，转印辊14和背压辊13固定在支架外框11下端部的两侧。背压辊13与转印辊14相对布置，导带7和织物经过两者之间。背压辊13为金属辊或橡胶辊。
圆网版辊10和转印辊14可以采用双伺服驱动，即圆网版辊10和转印辊14均由一独立伺服电机驱动；也可以采用单伺服驱动，即转印辊14由伺服电机驱动，而圆网版辊10则通过齿轮传动机构由该伺服电机带动旋转。
设有两个支架升降气缸12，它们用于使支架外框11上移以便更换圆网版辊10，其中，各支架升降气缸的活塞杆的一端支撑在支架外框11上并且各支架升降气缸以对置的一端固定在机架上。
圆网转印组件施压气缸15固定在支架外框11上方，用于对整个圆网转印组件3 施压以使转印辊14靠近或远离背压辊13。在根据图1的卧式圆网转移印花装置中，圆网转印组件3垂直于导带7安装，并且圆网转印组件施压气缸15的施压方向垂直于导带7向下。圆网印版10和转印辊14沿着彼此平行的轴向延伸方向布置。
圆网印版14的外周表面和转印辊13的外周表面可以彼此抵靠或分开。特别地，在一实施例中，转印辊14两端分别设有合适的致动器(例如液压缸、气压缸或电动缸)(未示出)，用于驱动转印辊14选择性地运动至合近位置和离远位置。在合近位置中，转印辊14抵近圆网版辊，由此使得圆网版辊与转印辊14之间的间隙为0.3±0.1mm；在离远位置，转印辊14不抵近圆网版辊10。因此实现首先利用圆网版辊10将花型图案印制在转印辊14上，再经转印辊14将花型图案印制在织物8上，从而不仅降低制版成本，而且实现了无纸化的转移印花。
转印辊14直径与圆网版辊10相同，或是圆网版辊10直径的整倍数。转印辊14的表面被无缝橡胶或树脂包覆，因此对水性墨水亲和性好，该表面的邵氏硬度为70～85度。
所述背压辊13为金属辊或橡胶辊，为可转动而不可移动的辊。
在以织物8为例的情况下，通过本公开的卧式圆网转移印花装置对织物印花的过程如下：
织物8经张力调节装置和纠偏装置的精确调节定位之后，随着由中心辊伺服电机驱动的中心辊的转动，织物8被带动通过导辊进入所述卧式圆网转移印花装置。接下来参照图1和图2进行描述，织物8经过进布装置1之后与上胶后的导带7贴合，然后进入圆网转印组件3进行印花。通过控制转印辊14两端的致动器，使圆网转印组件3中的圆网版辊10与转印辊14合近，利用内置刮刀对圆网所施加的压力，随着自动连续供墨系统的运行，实现将图案花型印制在转印辊14上。然后经由圆网转印组件施压气缸15对整个圆网转印组件3施压，即可使转印辊14将图案花型转印到织物8上。在此期间，自动控制系统通过伺服电机控制每个圆网转印组件3的速度以及被施加的压力，通过多个圆网转印组件印制完成套色印花，之后将经印花的织物8连同导带7通过导辊引出，进入后续固色水洗等工序环节。导带7经过印花区域之后经导带清洗装置4清洗，并再次经由导带纠偏装置6纠偏之后重新循环运行。
刮刀组件(也可称为刮印机构)布置在圆网印版10的中空内部并且沿着圆网印版10的轴向方向延伸。刮刀组件可以为适用于圆网转移印花装置的任意适当类型。比如，刮刀组件可以包括分布有孔眼的色浆管、刮刀、刮刀夹具、刮刀架、防溅挡板 等。刮刀可以为橡胶刮刀、金属刮刀、高分子材料刮刀等。优选地，刮刀可以是具有一定弹性的金属刮刀，比如钢刮刀。刮刀的选择应根据织物品种和花型结构的不同而定，以保证适当的给浆量和渗透性，从而获得理想的印制效果。
刮刀通过刮刀夹具安装在适当的刮刀架上，该刮刀架可以在圆网印版内部平移和转动，以便对刮刀在圆网印版内部的位置、取向、以及刮刀与圆网印版内表面的接触压力进行调节。所述调节通过根据本公开的刮刀组件调节机构来进行实施，如将在下文详细描述的那样。
如图2和图3所示，在每个圆网转印组件中还设有刮刀组件(也可以称为“刮印机构”)104，该刮刀组件包括安装在刮刀架上的刮刀，刮刀内置于圆网版辊10中。刮刀可以是金属刮刀、磁棒式刮刀或磁棒-刮板组合式刮刀。通过刮刀调节机构来调节刮刀相对于圆网版辊10的位置和压力，从而控制上墨量。
下面参照图3来描述根据本公开的一个实施例的刮刀调节机构105的具体结构。
刮刀调节机构105包括主调节机构和次级调节机构。所述主调节机构包括摆臂201和摆臂致动装置202。摆臂201由第一摆臂部分201’和第二摆臂部分201”两个部分构成。在图3所示的垂直于圆网印版的轴向的平面(即，纸张平面)中，第一摆臂部分201’为水平延伸的摆臂部分，第二摆臂部分201”为倾斜延伸的摆臂部分。其中，第二摆臂部分201”的一端成角度地固定在第一摆臂部分201’的一端，而摆臂致动装置202可枢转地连接至第一摆臂部分的另一端。第一摆臂部分和第二摆臂部分之间的夹角α可以根据实际情况进行选择。优选地，第一摆臂部分和第二摆臂部分之间的夹角α为钝角。
第一摆臂部分201’和第二摆臂部分201”可以分别形成为独立的部件，然后将这两个部件固定连接(比如，焊接等)而形成摆臂201。替代地，第一摆臂部分201’和第二摆臂部分201”可以形成为一体。另外，第一摆臂部分201’和第二摆臂部分201”的横截面(即，垂直于其轴向方向的截面)优选为矩形，从而使得第一摆臂部分201’和第二摆臂部分201”具有四个平坦的外表面。但是本公开不局限于此，可以将第一摆臂部分和第二摆臂部分设计成具有其它合适形状的横截面。
在第一摆臂部分201’上设置有枢转部203。在根据图3所示的实施例中，该枢转部203具有用于接纳摆臂枢轴(未示出)的枢轴孔，摆臂枢轴可以固定地安装在比如圆网转印组件的框架上，该枢轴孔使得第一摆臂部分201’可以围绕摆臂枢轴转动。其中，枢轴孔的轴线方向垂直于图3所处的纸张平面。该枢轴孔可以根据需要设置在第 一摆臂部分的两个端部之间的任一位置处。优选地，枢轴孔设置在靠近第一摆臂部分的中间位置处。在图3所示的实施例中，枢轴孔设置在从第一摆臂部分的外表面向上凸出的凸起部中，但本公开不局限于此。比如，枢轴孔可以设置在从第一摆臂部分的外表面向后凸出的凸起部中。凸起部可以与第一摆臂部分形成为一体。但是也可以将凸起部设置成单独的部件，然后通过焊接、螺纹连接等各种手段将该凸起部固定到第一摆臂部分的适当位置处。凸起部可以具有任意适当的形状和构造，比如圆柱形、多边形等。另外，枢轴孔可以是通孔，也可以是盲孔，只要该盲孔能够具有一定的深度用于接纳枢轴、并能够使摆臂围绕其转动即可。
刮刀组件104可以连接到第二摆臂部分201”上，并且可以跟随第二摆臂部分201”一起运动。
摆臂致动装置202可以是任意类型的施压装置，比如气压缸或液压缸等。摆臂致动装置202用于致动摆臂201，从而通过使摆臂201带动刮刀组件104一起运动来调节刮刀组件104在圆网版辊内的位置，从而使得刮刀以一定的取向靠近或远离圆网版辊的内表面，其中，所述靠近圆网版辊的内表面包括以一定的压力接触圆网版辊的内表面。
以图3为例来具体描述该过程。摆臂致动装置202可以在第一摆臂部分201’的端部(即，二者的连接部位)施加力，使得第一摆臂部分201’的该端部向上或向下运动。此时，第一摆臂部分201’围绕在其凸起部位置处的摆臂枢轴转动，从而导致第一摆臂部分201’的另一端(即，第一摆臂部分与第二摆臂部分连接的端部)向下或向上运动。第一摆臂部分201’的运动使得第二摆臂部分201”产生相应的运动，进而通过第二摆臂部分201”使刮刀组件104在圆网版辊内运动，直至刮刀运动到期望的位置为止。
进一步地，根据本公开的一个实施例，用于卧式圆网转移印花装置的刮刀调节机构105的次级调节机构包括次级刮刀压力调节组件300和次级刮刀位置调节组件400。其中，次级刮刀压力调节组件300布置于摆臂的第一摆臂部分201’，而次级刮刀位置调节组件400布置于摆臂的第二摆臂部分201”。所述次级刮刀压力调节组件300和次级刮刀位置调节组件400分别用于对刮刀在圆网版辊中的压力和位置进行精细调节。优选地，该精细调节手动进行，并且该精细调节适用于在通过主调节机构将刮刀基本调节到位之后进行，这使得能够以简单的方式来对刮刀的位置和压力进行更精细的调节与控制，从而有助于提高卧式圆网转移印花装置的印花品质、并有助于降低刮刀和圆网的磨损。
优选地，根据本公开的一个实施例，摆臂的第一摆臂部分201’和第二摆臂部分202”可以分别被设计成具有中空空腔。这样，可以将次级刮刀压力调节组件300设置在第一摆臂部分201’的中空空腔中，而将次级刮刀位置调节组件400设置在第二摆臂部分202”的中空空腔中。这种设计和布置方式一方面可以节省材料、降低整个刮刀调节机构的重量；另一方面，由于次级刮刀压力调节组件和次级刮刀位置调节组件设置在摆臂的中空空腔内部，从而节省了其在卧式圆网转移印花装置中所占据的空间，更重要的是，可以保护次级刮刀位置调节组件和次级刮刀压力调节组件不受外部环境的影响和破坏。但是，本公开不局限于此，可以根据需要将次级刮刀压力调节组件和次级刮刀位置调节组件设置在摆臂外部的合适位置中。
刮刀压力调节组件300主要包括：压力调节手轮301、压力调节螺母丝杠机构302、压力调节滑动部件303和抵压部件304。其中，压力调节螺母丝杠机构302沿着第一摆臂部分的轴向方向延伸，且优选布置在第一摆臂部分的中空空腔内部。压力调节螺母丝杠机构302的一端(如图3所示，该端为远离摆臂致动装置的一端，亦即靠近第二摆臂部分的一端)连接至压力调节手轮301，而另一端(如图3所示，该端为靠近摆臂致动装置的一端，亦即远离第二摆臂部分的一端)连接至压力调节滑动部件303。
第一摆臂部分的上壁设置有一条狭缝，该狭缝位于第一摆臂部分201’的靠近摆臂致动装置202的一端，并且该狭缝贯穿该上壁且沿着第一摆臂部分的轴向方向延伸一定的长度。压力调节滑动部件303设计成通过该狭缝承坐在第一摆臂部分201’的上壁上，并且因此被分成两个部分，即：位于第一摆臂部分201’外部的第一滑动部和位于第一摆臂部分201’的中空空腔内的第二滑动部，其中，第二滑动部用于与压力调节螺母丝杠机构302相连接，以便使压力调节滑动部件303在压力调节螺母丝杠机构302的带动下滑动。这样，当转动压力调节手轮301时，压力调节螺母丝杠机构302旋转，从而使得压力调节滑动部件303能够在狭缝中沿着狭缝的延伸方向滑动。
如图3所示，压力调节滑动部件303的第一滑动部具有倾斜的上表面，使得第一滑动部的高度沿着第一摆臂部分201’的轴向方向逐渐变化。在图3所示的实施例中，第一滑动部的高度沿着第一摆臂部分的轴向方向从左至右逐渐升高。但本公开不局限于此，比如可以根据需要将第一滑动部的高度设计成沿着轴向方向从左至右逐渐降低。
抵压部件304设置在压力调节滑动部件303的上方。优选地，抵压部件304设置在压力调节滑动部件303的上方的固定位置处。压力调节滑动部件303的第一滑动部 的倾斜上表面与抵压部件304配合使用，以便调节刮刀与圆网版辊之间的接触压力。具体来说，首先通过主调节机构和/或次级刮刀位置调节组件将刮刀调节至与圆网版辊基本接触的适当位置，此时抵压部件304与压力调节滑动部件303的第一滑动部的倾斜上表面靠近或接触。然后，转动压力调节手轮301使压力调节滑动部件303向期望的方向滑动，由于所述倾斜上表面的高度是逐渐变化的，因此抵压部件304与该倾斜上表面的接触压力、以及因此通过倾斜上表面而施加在第一摆臂部分201’上的力逐渐变化，这进而导致第一摆臂部分201’围绕摆臂枢轴做小范围的枢转运动，从而带动刮刀组件104运动并因此改变刮刀与圆网版辊的接触压力。
在根据本公开的一个实施例中，抵压部件304呈圆柱形状，其轴向方向垂直于图3所处的纸张平面。优选地，抵压部件304可以是能够围绕其中心轴线转动的圆柱形部件(比如，滚轮轴承等)。在该情况下，由于抵压部件304可以在第一滑动部的倾斜上表面上滚动，因此抵压部件304与第一滑动部的倾斜上表面之间的摩擦力较小。在进行压力调节时，能够使压力调节滑动部件303相对于抵压部件304更容易地滑动，从而减小转动压力调节手轮301时所需的力。这样，能够更容易地手动调节刮刀与圆网的接触压力。
次级刮刀压力调节组件还可以包括压力指示元件305，用于指示压力的调节幅度。在图3所示的实施例中，压力指示元件305包括压力标尺和压力幅度指示件。压力标尺上刻有用于表示压力调节幅度的数值。压力标尺固定在第一摆臂部分的外表面上，靠近压力调节手轮的那一端。压力标尺可以通过各种连接方式固定在第一摆臂部分上，比如螺钉连接、粘合、焊接等。压力幅度指示件固定在压力调节螺母丝杠机构302上，随着压力调节螺母丝杠机构302的运动而沿着第一摆臂部分的轴向方向前后滑动，从而根据其指示的压力标尺上的数值来确定压力的调节幅度。在图3所示的实施例中，由于压力幅度指示件位于第一摆臂部分的中空空腔内部，因此在第一摆臂部分的相应位置上设置有一条沿着第一摆臂部分的轴向方向延伸的狭缝，以便使压力幅度指示件可见。狭缝的长度基本等于或大于压力标尺的长度。
下面继续参照图3，详细地描述根据本公开的一个实施例的刮刀调节机构中的次级刮刀位置调节组件400。在通过主调节机构将刮刀组件基本调节到适当的位置之后，通过次级刮刀位置调节组件400对刮刀位置进一步地进行精细调节；或者在印花速度改变时，通过次级刮刀位置调节组件400对刮刀位置进行相应的调节。
次级刮刀位置调节组件400主要包括：位置调节手轮401、位置调节螺母丝杠机 构402、位置调节滑动部件403、和刮刀固定手轮404。其中，位置调节螺母丝杠机构402沿着第二摆臂部分的轴向方向延伸，且优选地布置在第二摆臂部分201”的中空空腔内部。位置调节螺母丝杠机构402的一端(如图3所示，该端为远离第一摆臂部分的一端)连接至位置调节手轮401，而另一端(如图3所示，该端为靠近第一摆臂部分的一端)连接至位置调节滑动部件403。
优选地，位置调节滑动部件403以可滑动的方式布置在第二摆臂部分201”的中空空腔内。当转动位置调节手轮401时，位置调节螺母丝杠机构402旋转，从而使得位置调节滑动部件403能够在第二摆臂部分的中空空腔内沿着第二摆臂部分的轴向方向滑动。
相应地，在第二摆臂部分的靠近位置调节手轮401的一端设置有第一狭缝405。刮刀组件104的刮刀架通过该第一狭缝405以任意适当的方式连接至位置调节滑动部件403，从而能够跟随位置调节滑动部件403的滑动而上下移动，以便改变刮刀相对于圆网版辊的位置。第一狭缝的长度设计成不妨碍刮刀组件104的运动，以便使刮刀组件104能够在期望的位移范围内自由运动。
在第二摆臂部分上还设置有沿着第二摆臂部分的轴向方向延伸的第二狭缝406，第二狭缝406与第一狭缝405设置在第二摆臂部分的不同壁上。刮刀固定手轮404通过第二狭缝406而螺纹连接到位置调节滑动部件403上。在旋松刮刀固定手轮404时，刮刀固定手轮404能够沿着第二狭缝406的延伸方向在第二狭缝406内上下运动。同样地，第二狭缝406的长度设计成不妨碍刮刀固定手轮404的运动，以便使刮刀固定手轮404能够在期望的位移范围内自由运动。
在进行刮刀位置调节时，首先旋松刮刀固定手轮404，然后手动地旋转位置调节手轮401，以便使位置调节螺母丝杠机构402转动，从而带动位置调节滑动部件403在第二摆臂部分的中空空腔内上下滑动。位置调节滑动部件403进而带动刮刀组件104上下运动，以便将刮刀精细地调节至期望的位置。在将刮刀调节至期望的位置之后，旋紧刮刀固定手轮404，通过使刮刀固定手轮404、第二摆臂部分201”的壁部、以及位置调节滑动部件403三者紧紧抵压在一起而固定刮刀组件104，使其不再能够移动。
可选地，次级刮刀位置调节组件400还包括位置指示元件，用于指示位置的调节幅度。位置指示元件可以与压力指示元件具有类似的结构，并且以类似的连接方式固定在第二摆臂部分的适当位置处。在此不再进行详细的描述。
根据本公开的一个实施例，次级刮刀位置调节组件400能够调节的位置幅度为±10 mm。刮刀位置可以随印刷速度的改变而改变。以全棉织物印花为例，在全棉梭织布的克重为150g/m 2、印刷速度为60m/min时，将刮刀位置控制手轮调节为0mm，则当印刷速度增大到80m/min时，刮刀位置控制手轮调节为+4mm；当印刷速度增大到100m/min时，刮刀位置控制手轮调节为+6mm。
根据本公开的一个实施例，可以在圆网版辊的两个轴端各设有一个根据本公开的刮刀调节机构105。所述两个刮刀调节机构105可以分别具有各自的摆臂枢轴、并且分别围绕各自的摆臂枢轴枢转。但是，所述两个刮刀调节机构105也可以借助于同一摆臂枢轴连接在一起，并且能够围绕该同一摆臂枢轴枢转。在该实施例中，优选地，可以对每个刮刀调节机构105单独进行调节。
本公开可以包括在此隐含或明确公开的任何特征或特征组合或其概括，不局限于上述罗列的任何限定的范围。在此所述的有关任何元件、特征和/或结构布置可以以任何适合的方式组合。
以上公开的特定实施例仅是示例性的，对于受益于本文的教导的本领域技术人员来说显然的是，可以以不同但等同的方式修改和实施本公开。例如，可以按不同的顺序执行上述方法步骤。此外，除了以下权利要求中所述的之外，并不限制本文示出的构造或设计的细节。因此显然的是，可对以上公开的具体实施例进行改变和修改，并且所有这些变型都被认为是落入本公开的范围和精神之内。因此，本文寻求的保护在所附的权利要求中列出。
