纸张压纹辊01
1、石
1, stone roller
石辊为优质天然花岗石或人造石组成。由于其表面共有无数微孔,使纸页易于从其表面脱开。天然花岗石抗弯强度差,不宜作下压辊,以免压断,也不宜过冷、过热或局部受热,否则会使辊面爆裂,表面不能接触强酸、强碱以免破坏表面光泽度。
The stone roller is made of high quality natural granite or artificial stone. Because of its numerous pores, the surface of the paper is easily removed from its surface. The bending strength of natural granite is poor, it should not be used as a lower pressure roller so as not to break down, it should not be overcooled, overheated or partially heated, otherwise the roll surface will burst, and the surface can not contact strong acid and strong alkali to prevent surface gloss.
石辊与轴的结合是用两个左右旋向不同的螺母锁紧,在花岗石体与轴之间用水泥填塞或粘上。每一个石辊都有一定运转方向,使用时必须检查制造厂规定的转动方向与实际运动方向是否相符。
The combination of the stone roller and the shaft is locked by two left and right rotating nuts, and cement is filled or glued between the granite body and the shaft. Each stone roller has a certain direction of operation. When used, it must check whether the direction of rotation specified by the manufacturer is consistent with the actual direction of movement.
2、铜辊
2, copper roll
真空引纸辊、光泽辊等采用磷青铜制造。由于铜质辊面硬度低,不耐磨、钢度较差。因此,在生产、维修过程中,必须避免碰撞其表面。
The vacuum paper roller and the gloss roll are made of phosphor bronze. Because copper roller surface hardness is low, no wear resistance, poor steel. Therefore, in the production and maintenance process, we must avoid colliding the surface.
3、包胶辊
3. Bao Jiaogun
辊体材质为铸铁或铸钢,表面车有2.5~3.0mm螺距的左右螺纹。辊体外包硬质橡胶,其硬度一般在850(肖氏)左右。在压区线压相同时,橡胶硬度较高的辊子,脱水大,但横幅水分均一性差,因而对辊子的中高精度要求更高。当车速加快,压区线压力加大,辊面硬度要求相应提高,为确保有足够的强度的弹性,覆面胶采用聚氨脂型料覆面。
The material of the roller body is cast iron or cast steel, and the surface car has 2.5~3.0mm pitch left and right threads. The hardness of the roller body is about 850 (Shaw). At the same time in the pressure zone, the roller with high rubber hardness is dehydrated, but the uniformity of the horizontal moisture is poor. Therefore, the roller has higher precision and higher accuracy. When the speed of the car is quicker, the pressure of the pressure zone is increased, the hardness of the roller face is required to be improved accordingly. In order to ensure the elasticity with sufficient strength, the covering adhesive is used to cover the surface of the polyurethane material.
