Description
本发明涉及纺纱细纱机须条的输送机构,一般称环锭细纱机牵伸系统,特别涉及其下纺纱组件。The present invention relates to the conveying mechanism of the strands of the spinning frame, which is generally called the drafting system of the ring spinning frame, and particularly relates to the lower spinning assembly.
如图1所示,中国专利文献CN112760766A公开的环锭纺细纱机的纤维须条输送机构,其后罗拉胶辊35、中罗拉胶辊4、前罗拉胶辊30顺时针旋转,后罗拉轴32、中罗拉轴3和前罗拉轴1逆时针旋转,把纱线F输送到导纱钩36再到钢领38,绕在锭管37旋转加捻形成纱线L,其中后罗拉轴32、中罗拉轴3、前罗拉轴1是主动旋转,后罗拉胶辊35、中罗拉胶辊4、前罗拉胶辊30是被动旋转,一般中罗拉轴3的转速是后罗拉轴32的1.1-3倍,前罗拉轴1的转速是中罗拉轴3的10-150倍,粗纱经过牵伸变细。由于中罗拉胶辊4和前罗拉胶辊30速度比大,须条急剧变化,因此,在此中间设定上销盖板6、下销2、输送带7而形成稳定的摩擦空间以控制须条。弹簧罩15被摇架9下压后,经过上销弹簧16传递到盖板支撑件13,上销盖板6通过铰接块17和铰接块座18与盖板支撑件13连接,使上销盖板6得到一个下压力,上销盖板6弧面和下销2弧面之间形成一个稳定配合的间隙,须条一直由输送带7带动在该间隙中输送向前,须条一直在下销2上滑动摩擦。这样,纺纱须条F一直在下销2的工作段弧面摩擦。上述机构纺不同粗细纱线、不同原料时需要不同的工作段弧面配合,这样需要更换整个下销,并且,如果整根下销改变弧面,那么隔距块也必须更换,会导致成本增加和管理混乱。As shown in Figure 1, the fiber strand conveying mechanism of the disclosed ring spinning frame of Chinese patent document CN112760766A, thereafter the roller rubber roller 35, the middle roller rubber roller 4, the front roller rubber roller 30 rotate clockwise, and the rear roller shaft 32 , the middle roller shaft 3 and the front roller shaft 1 rotate counterclockwise, the yarn F is delivered to the yarn guide hook 36 and then to the steel collar 38, and the yarn L is formed by rotating and twisting around the spindle tube 37, wherein the rear roller shaft 32, the middle roller shaft The roller shaft 3 and the front roller shaft 1 are actively rotating, and the rear roller rubber roller 35, the middle roller rubber roller 4, and the front roller rubber roller 30 are passively rotating. Generally, the speed of the middle roller shaft 3 is 1.1-3 times that of the rear roller shaft 32 , the speed of the front roller shaft 1 is 10-150 times that of the middle roller shaft 3, and the roving becomes thinner through drafting. Because the speed ratio of the middle roller rubber roller 4 and the front roller rubber roller 30 is large, the whiskers change rapidly. Therefore, the upper pin cover plate 6, the lower pin 2, and the conveyor belt 7 are set in the middle to form a stable friction space to control the whiskers. strip. After the spring cover 15 is pressed down by the cradle 9, it is transmitted to the cover support 13 through the upper pin spring 16, and the upper pin cover 6 is connected with the cover support 13 through the hinge block 17 and the hinge block seat 18, so that the upper pin cover The plate 6 gets a downward pressure, and a stable fit gap is formed between the arc surface of the upper pin cover plate 6 and the arc surface of the lower pin 2. The whiskers are always driven by the conveyor belt 7 and transported forward in the gap, and the whiskers are always on the lower pins. 2 on sliding friction. Like this, the spinning sliver F always rubs against the arc surface of the working section of the lower pin 2. When the above-mentioned mechanism spins yarns of different thicknesses and different raw materials, different arc surfaces of the working section need to be matched, so that the entire lower pin needs to be replaced, and if the entire lower pin changes the arc surface, the spacer must also be replaced, which will increase the cost and management chaos.
传统的环锭细纱机纺纱都是一股粗纱纺制一股细纱,缆型纺是将一股喂入的粗纱先行分割成两股或两股以上的纤维束,每一股纤维束在纺纱力的作用下绕自身的轴线旋转加捻,接着所有带有一定捻度的被分割纤维束都汇交在一起,再绕着纱线的轴心加捻成一股纱线。如中国专利文献CN101736470A公开的芳砜纶纤维缆型纺纱方法,中国专利文献CN101392421A公开的环锭细纱机的缆型纺装置,须条在经过前罗拉胶辊以后,经过分梳辊分梳,然后加捻成纱线,缆形纺需要在前罗拉胶辊、前罗拉轴之间设置分割棍以及一系列加压装置,从而增加零件、增加操作难度和成本。In traditional ring spinning machine spinning, one roving is spun into one spun yarn. Cable spinning is to divide a fed roving into two or more fiber bundles, and each fiber bundle is spun Under the action of the yarn force, it rotates and twists around its own axis, and then all the divided fiber bundles with a certain twist converge together, and then twist around the axis of the yarn to form a strand of yarn. As disclosed in the Chinese patent document CN101736470A, the cable-type spinning method of sulfonamide fibers, and in the cable-type spinning device of the ring spinning frame disclosed in the Chinese patent document CN101392421A, the strands are combed through the carding roller after passing through the front roller rubber roller. Then it is twisted into yarn, and the cable spinning needs to install a split roller and a series of pressing devices between the front roller rubber roller and the front roller shaft, thereby increasing the number of parts, increasing the difficulty of operation and cost.
根据公知技术,在前罗拉和下销之间安装集合器能明显改变纱线质量,减少毛羽,如中国专利文献CN205398820U公开的复合式压力棒集合器,其包括压力棒和两个门形集合器,在所述压力棒的中部穿接有隔距块,所述门形集合器包括门梁和连接在所述门梁两端 的前伸折臂,两个所述前伸折臂的前端头折角相对,在所述门梁中开有轴向通孔,所述通孔的孔径略大于所述压力棒的直径;所述门形集合器从所述压力棒的端部穿接在所述压力棒上,并与所述隔距块保持相反的朝向。但其需要单独增加集合器,而且,集合器的结构也很复杂。如果通过增加集聚槽也需要更换整个下销。According to the known technology, installing a collector between the front roller and the lower pin can significantly change the yarn quality and reduce hairiness, such as the composite pressure rod collector disclosed in Chinese patent document CN205398820U, which includes a pressure rod and two door-shaped collectors , the middle part of the pressure rod is pierced with a spacer, the door-shaped collector includes a door beam and a forward folding arm connected to both ends of the door beam, and the front ends of the two forward folding arms have knuckles In contrast, an axial through hole is opened in the door beam, and the diameter of the through hole is slightly larger than the diameter of the pressure rod; the gate collector is connected to the pressure rod from the end of the pressure rod , and keep the opposite direction from the distance block. But it needs to increase the collector separately, and the structure of the collector is also very complicated. If the accumulation groove is added, the entire lower pin needs to be replaced.
