The needle cloth cover with a new type of carding machine, the needle (1) and bottom cloth (2), needle (1) according to the implantation of base cloth (2) of the state is divided into knee bend needle and straight leg needle two, two tip plane and the bottom cloth to form a needle needle angle, to meet the Tg or TG alpha =0.0168168 alpha = 0.0270270. When the steel needle (1) is bent knee needle shape, the bending knee point connection is parallel to the needle base surface height (C) of the implanted base cloth. It can also be parallel to the knee point connection of the knee steel needle tip, that is to say, the angle angle is also equal to the steel pin base of the implanted base cloth (2). By using this new needle cloth cover plate of carding machine, using the angle of needle tip and bottom surface to realize the difference between heel and toe; not only solve the steel frame or aluminum bone heel and toe processing quality is not controllable, affect the distance accurately layout and sort the problem, but also reduce the production process, simplify installation mode, reduce the maintenance cost.

一种新型梳棉机用盖板针布条
本技术涉及一种盖板针布条,具体涉及一种新型梳棉机用盖板针布条。
技术介绍
梳棉机是通过包覆在刺辊、锡林、道夫和盖板上的针布,对棉束、纤维进行分梳、除杂、均匀、混合、伸值、转移等作用。在纤维进入锡林-盖板工作区时,锡林和盖板的隔距分布是入口大出口较小,因此梳理逐步得到加强,促使每根盖板针布充分发挥对纤维分梳成单纤维状态。为了满足上述梳理工艺要求,就要使盖板存在踵趾差。传统盖板针布条中弯膝针形或者直脚针形的钢针植入底布,经磨削后其针尖面与底布的钢针基面平行,盖板针布条经过上夹、包夹在专用铁骨或者铝骨架之上,骨架两端有踵趾面,高度相差0.9mm或0.56mm,每根盖板与锡林齿面间的隔距在盖板入口趾面大,出口踵面小。也就是铁骨或铝骨架的入口铣削量多的一端为趾面,出口铣削量小的一端为踵面;盖板针布条就装这样的踵趾面上形成踵趾差。由于传统盖板针布条和铁骨包覆成盖板系统,其一受铁骨或铝骨架的转运、加工和撞击变形等,易使盖板针布针高累积超差,与锡林针布发生接针损伤针布,严重影响梳理质量;其二每次更换盖板针布,需要对铁骨或铝骨重复修磨,机械强度、精度稳定 ...
