一、概述 ZKD复合式气功气动刮刀是我厂引进消化吸收国外先进技术，结合我国国情而研制生产的一种新型卫生纸起皱刮刀。该刮刀结构简单，调整方便，通过气缸推动刮刀架转动，气囊推动后压标对刀片加压的复合运动，能自动弥补因烘缸缸面不平而不起皱或起皱不均匀的缺陷，广泛适用于高低速纸机。 二、结构原理 ZKD复合式气动刮刀是由气缸（9）、杠杆（8）、刮刀支撑架（7）、气囊（6）、前后压标（3）、刀片（2）等几大部分组成。 其原理为，气缸推动杠杆摆动带动刮刀架转动，使刮刀靠近烘缸面（一般调为1-1.5mm）不接触烘缸，然后给气囊冲气加压，气囊推动后压标对刀片加压，从而使刮刀紧贴烘缸面。若烘缸表面不平，通过烘缸表面对刀片的反作用力，自行调节前后压标，使刮刀作用在烘缸轴线方向压力均匀，从而使纸面起皱均匀。 三、优越性 ZKD复合式气动刮刀与普通刮刀相比，具有以下优越性： 1、由于压缩空气的弹性作用及各压标的独立作用，能确保烘缸表面与刀片的接触线压力始终保持一致。保证纸张起皱均匀。 2、由于烘缸表面与刀片的接触线压始终保持一致，从而使刮刀刀沿的磨损均匀。减少刀片磨刀次数，提高生产效率。 3、由于特殊的复合式加压，减少了烘缸表面的磨损。具有保护烘缸缸面，延长烘缸使用寿命的优点。 4、刮刀架的特殊构造，提高了刮刀刀片的利用率，可在50mm-120mm范围内调整使用，延长了刮刀刀片的使用寿命。 5、由于复合式加压方式，气缸的推动可调，气囊的压力可调，所以皱纹度可自由调整。 6、操作简单，换刀迅速，一般只需30秒钟即可完成。 由于上述几点优点的综合作用，使停机的时间显著减少，对提高纸张抄造率、减少工人的劳动强度、提高产品的质量等均有显著效果。

First, an overview composite ZKD qigong-pneumatic blade factory is the introduction of digestion and absorption of advanced foreign technology, combined with China's national conditions and development and production of a new type of wrinkle-free toilet paper scraper. The simple structure of the scraper, to facilitate adjustment by promoting the scraper plane rotating cylinder, pressure gasbag promote post-marked pressure on the blade of the complex, to make up for the automatic dryer cylinder as a result of uneven surface without wrinkling or uneven wrinkle defects Applicable to a wide range of high low-speed paper machine. Second, the ZKD composite structure of the principle of pneumatic cylinders by the scraper (9), leverage (8), supporting frames scraper (7), balloon (6), before and after the standard pressure (3), blade (2), and so most of the few Composition. The principle that the cylinder drive swing lever to promote scraper plane rotation, so close to the blade surface Dryer (adjusted for normal 1-1.5mm) non-contact dryer, and then to the red balloon gas pressure, air pressure to promote post-marked increase on the blade Pressure, so that the blade surface close to Dryer. If the dryer uneven surface, the surface of the blade through the dryer's reaction, self-regulation before and after the standard pressure, so that the role of the scraper in the direction of the axis of pressure Dryer uniform, so that the uniformity of paper wrinkling. Third, the ZKD superiority of the compound with the general aerodynamic blade scraper, has the following advantages: 1, due to the flexibility of the role of air pressure and the subject of an independent role to ensure that the dryer on the surface of the blade with the pressure on the contact line has always been consistent . To ensure uniformity of paper wrinkling. 2, due to the dryer with the blade surface pressure of the contact line has always been consistent, so that the knife blade along the wear uniform. Brothers to reduce the number of blades, increasing productivity. 3, as a result of the special compound pressure to reduce the wear and tear on the surface of the dryer. Dryer surface protection Cylinder, Dryer extend the service life of the merits. 4, the special structure of the scraper plane, blade scraper to increase the utilization of the available 50mm-120mm in the range of adjustment, to extend the service life of the scraper blade. 5, due to pressure composite manner, driving tunable cylinder, air pressure adjustable, so be free to adjust the degree of wrinkles. 6, is simple, quick tool change is generally only 30 seconds to complete. As a result of a few of the advantages of an integrated, so that's down significantly reduce the time for making copy paper to raise rates, reduce labor intensity and improve product quality, and so have a significant effect.
