outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 纵观各种子棉清理设备,其清理部件主要有刺钉滚筒、齿条滚筒、锯片滚筒三种形式。不管何种形式的滚筒,都需结合周围部件完成清理。为了提高清杂效率,可同时使用几种不同形式的清理设备清杂。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 1.刺钉滚筒清花机<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 刺钉滚筒式子棉清理机,也称刺钉滚筒清花机或刺钉式清花机。它应用较早,早先用于加工手工摘棉,现今与其他设备配合使用,可以加工机采棉和手工快速采棉。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 刺钉滚筒式清理部件由刺钉滚筒和下弧形筛网构成,利用筛分作用原理实现杂质与子棉分离。子棉进入刺钉滚筒与排杂网之间,在刺钉连续不断的冲击下,沿排杂网表面滚翻、碰撞、抖动,促使棉纤维中的尘杂分离,并从排杂网孔排出。同时使子棉也得到开松。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 影响刺钉滚筒清花清杂效能的因素有:<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (1)子棉的特性:品质好、含水率低的子棉,棉纤维弹性大,杂质易分离,清杂效能高。反之,品质差,含水率高的子棉纤维弹性小,杂质易与纤维纠缠在一起,不易分离,清杂效能低。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (2)清花机的生产率:在一定条件下,清理子棉的数量越多,清杂效能越差。因此,清花机的技术规格应根据处理子棉量和含杂量而定,刺钉式清花机的清杂效率与生产率的关系如图7-17所示。</span></p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; font-size: 14px; text-align: center;

margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 对于多滚筒清花机,为防止子棉团堵塞,保证清花机的正常运转,刺钉滚筒表面线速度应随子棉清理逐个递增,递增率应大于3%。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (4)筛网的结构形式及其清洁程度:刺钉滚筒清花机的排杂网有铁丝编织网、钢板冲孔网、格条栅筛网和钢板网等类型。除杂筛网的清杂效率与筛孔的有效面积、筛孔的排列、筛孔的形状及筛网表面积等有关。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 筛孔有效面积(S<sub style="max-inline-size: 100%; margin: 0px; padding: 0px; font-size: 10.5px;

margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (5)刺钉尖端与除杂筛网表面的距离:这是子棉清理过程的有效空间,称“清理过道”。要想保证这个过道的畅通。就要求:刺钉在滚筒表面分布适中;刺钉到网面间距应根据子棉的品质及棉瓣的大小确定。此间距大小应以子棉在网面上能向前滚动为宜,一般取18～25mm。对于多滚筒清花机,此间距应顺着子棉的打松、从进棉口到出棉口逐渐加大,在出棉口处,该间隙宜大不宜小。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 除杂筛网应与刺钉滚筒相配合,其形状一般呈圆弧形。除杂筛网的圆弧对应于刺钉滚筒的中心角φ(图7-19),这是一个比较重要的参数。其数值过大,子棉易随刺钉返回而造成重复打击,产生棉结、索丝等疵点;反之,除杂筛网之间不可避免地出现直线连接段,子棉易在此处停留,引起堵塞,其次,还减少了刺钉与除杂筛网的配合作用范围,影响清杂效率。一般φ应控制在110°～115°。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (6)刺钉滚筒上的刺钉及滚筒直径和数量:刺钉滚筒大体有三种。一种是大直径滚筒,刺钉细、矮,这种形式见于80A型轧花机的清理部件和冲击式清花机的喂棉滚筒。直径大,子棉匀布于滚筒表面的机会多,小矮式刺钉对子棉起抖动作用,出来的棉花比较均匀。另一种是中等直径滚筒,刺钉相对高且粗,松懈子棉能力强。还有一种小直径滚筒,这种滚筒缠绕效果好,见于冲击式清花机的软特杂回收辊,能回收绳索、布条、粗长麻等杂质。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 刺钉滚筒清理时易对子棉形成搓揉,联合打击的滚筒数目过多就会形成索丝,一般以3～7辊为宜。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 对于五六个滚筒的多滚筒清花机,可将第一个刺钉滚筒改成打僵滚筒,并相应地配上排杂网,且用电动机单独驱动,就成为开僵清花两用机。当加工低级子棉时,先由打僵滚筒强行开松,再由刺钉滚筒打松;当加工白棉时,子棉由间道板引导直接进入刺钉滚筒。这种一机两用的形式既方便,又减少了单机配置。打僵滚筒由4～6根铸铁斜齿条围装在薄钢板圆筒表面而成。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 打僵滚筒直径可与刺钉滚筒相同。为保证打僵滚筒对僵瓣的强行开松作用,其表面线速度应控制在20～25m/s,铸铁斜齿条与除杂网的距离为16～18mm,格条栅间隙为6～8mm。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 传统清花机和机采棉设备中各类倾斜式子棉清理机均属六滚筒刺钉清花机。倾斜式子棉清理机主要由6个清花刺钉辊、格条栅、阻风阀、机器侧壁、溜杂槽及传动系统等几部分组成。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 一般需要与沉积箱、风机、沙克龙等设备配套使用,其配套工艺如图7-20所示,刺钉滚筒的结构如图7-21所示。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 齿条滚筒式清理机是在刺钉滚筒清花机的基础上发展起来的,其原理与先前认为的大滚筒小刺钉清理有相似之处,尽可能将子棉铺开。齿条滚筒式清理既可以清除子棉中的大颗粒杂物,如铃壳、僵瓣,也可以清除子棉中的小颗粒杂物,如棉叶、不孕子,还能起到松棉的作用。齿条滚筒式清花机的结构形式较多,但就杂质和子棉分离的作用原理而言,可分为抛掷式剥铃机和擦拭式提净机两种。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 擦拭式提净机是利用“擦拭抖动结合惯性离心力”的作用,使子棉与杂质分离。具体地说,是利用锯齿滚筒钩带子棉时,与刷条产生擦拭和抖动作用,使铃壳、僵瓣等不易被锯齿钩住的杂质抖落,抛离锯齿滚筒与子棉分离。该形式提净机多用于机采棉设备中的除棉秆机、大型轧花设备中的清理部、冲击式清花机下脚回收部。同样单纯的齿条滚筒不能单独完成清理过程。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 擦拭式提净机的清理部件由齿辊及周围的钢丝刷、尘棒、格条栅、刷棉辊构成。前道过来的子棉滑落到钢丝刷,再由与齿条滚筒齿尖紧密接触的钢丝“喂、逼”到齿条滚筒上,这里钢丝刷起淌棉作用,淌棉角度一般取45°～50°。齿条滚筒不能反转,否则会引起钢丝的弯曲,影响清理效果。齿条钩拉含杂子棉时,由于充分暴露的子棉和杂质在同样转速下受离心力作用,经过与尘棒、格条栅的阻隔,使僵瓣、铃壳、不孕子、小花头被清出。齿辊钩住子棉之后被刷棉辊刷下。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 刷棉辊与齿辊转向相反,相对齿辊转速高一些。刷棉辊有两种结构形式,一种是毛刷滚筒,一种是叶片滚筒。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 齿条滚筒的锯齿齿形、锯齿齿距、齿尖角对生产率和清杂效率有一定的影响。锯齿条的横截面为U形,锯齿有直齿和弧形齿两种。直齿的抓棉性能较好,但也容易抓取杂质,影响清杂效率,且刷棉较困难。弧形齿克服了直齿的缺点,在国内外应用较广。锯齿齿距大,生产率高;齿尖角小,抓取子棉的能力强,但清杂效率下降且锯齿强度减弱。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 回收式子棉清理机是一种组合式子棉清理机,清理部分有刺钉滚筒清花单元,回收部分有齿条滚筒单元。该机主要由清理部分、回收部分及传动系统组成,如图7-22所示。</span></p><p style="max-inline-size: 100%;

(3)松棉效果好。能充分开松子棉,在松棉、除杂过程中对子棉纤维的损伤很小。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 影响冲击式清花机清杂效率的因素除子棉性状以外还有以下几方面。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ①刺钉滚筒、锯片滚筒的表面线速度及线速度比:冲击式清花机依靠刺钉和锯齿对子棉冲击、撕扯进行松棉除杂,因此,刺钉滚筒、锯片滚筒的表面线速度越高,子棉受到的冲击作用越强烈,清杂效率越高。但线速度过高会损伤纤维和棉子,产生棉结、索丝等疵点。为此,刺钉滚筒表面线速度不得超过11m/s,锯片滚筒的表面线速度不得超过8m/s。刺钉滚筒与锯片滚筒表面线速度比越大,子棉受到的撕扯作用就越强烈,松棉效率、清杂效率越高。但线速度比过大,会损伤纤维和棉子。通常,刺钉滚筒与锯片滚筒的线速度比不得超过1∶0.6。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ②锯片片距:锯片滚筒不仅起到冲击、阻滞子棉的作用,还起到筛分杂质的作用。一般地,锯片片距越大,杂质越容易从锯片之间坠落,清杂效率高,但同时也易排落单粒子棉,加重回收部分的负担,甚至造成落棉损失,增加衣分亏损。反之,大型杂质不易排落,清杂效率低。锯片片距应小于子棉瓣的腰径或单粒子棉的直径,要求小于20mm。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ③相邻锯片滚筒齿尖之间的距离:此距离大,清杂效率高,但排落的单粒子棉也多;反之,杂质难于排落,甚至发生锯齿相碰擦的事故。故此距不宜过大或过小,要求最小不低于5mm,最大不超过18mm。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ④刺钉滚筒刺端与锯片滚筒齿尖之间的距离:此距离大,既减弱了刺钉对子棉的打击作用力,也减弱了锯片滚筒对子棉的摩擦阻滞作用,使清杂效率下降;反之,清杂效率高,但会产生许多单粒子棉并造成落棉过多,严重时产生破子现象。此距离必须大于棉子的腰径,要求最小不低于9mm。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ⑤U形锯齿滚筒与钢丝刷条、格条栅及排杂调节板的间距:一般情况,这些间距大,杂质不易被U形锯齿滚筒钩住,清杂效率高,但排出机外的杂质中单粒子棉和小花头也多,衣亏加大;反之,清杂效率低。一般锯齿与圆钢格条栅的间距为10mm,锯齿与钢丝刷条的间距为0～5mm,锯齿与可调排杂板的间距为5mm。<br style="max-inline-size: 100%;
