钢筘是纺织机械的重要配件,广泛应用于丝、棉、毛、麻、化纤……等纺织行业中.随织物品种规格不同,对钢筘长度、密度,均有不同要求.密度与齿数的要求是十分严格的,某些品种的齿数绝对误差为零.随着化纤高密织物的迅速发展,特别是为了适应国防、化学、科研等单位的特殊需要,钢筘密度也越来越高.有的齿与齿之间的间隙仅为十几丝,甚至几丝.以往计算钢筘筘齿数目是通过蜗轮蜗杆转动在圆盘数板上计数的.由于在钢筘编织过程中,因调换筘片、扎丝等原因而中途停车时,筘齿计数就容易失灵,导致产品不合格,使纺织厂穿径不准,因而会造成浪费大量的人力物力,这是纺织机械上一个急待解决的严重问题. Reed is an important part of textile machinery, widely used in the textile industry such as silk, cotton, wool, hemp, chemical fiber ...... With the different varieties of fabric, the reed length, density, have different requirements. Density and number of teeth The requirements are very strict, the absolute error of the number of teeth of some varieties is zero.With the rapid development of chemical fiber high density fabric, especially in order to meet the special needs of national defense, chemical, scientific research and other units, the reed density is also getting higher and higher. Of the teeth and the gap between the teeth is only a dozen or even a few wires in the past calculated the number of reed dents by worm wheel rotation count on the number plates due to the reed weaving process, Film, tie wire and other reasons and stop the middle, the reed count is easy to malfunction, resulting in product failure, the textile mill is not allowed to wear, which will result in a waste of a lot of manpower and resources, which is an urgent need for textile machinery Serious Problem.
