There are two main methods of rewinding for metal coil slitter machine, one of which is the rubber ring rewinding method. For thick plates or wide strip plates, this method is usually used. Generally people use the rewinding rubber ring is mainly used oil-resistant, wear-resistant rubber, such as polyurethane, also known as Urethane, etc.. Another commonly used rubber.
These materials are chosen mainly because they all have high wear resistance and strong oil resistance, as well as strong corrosion resistance and deformation recovery ability. In practice, mainly according to the different metal slitter equipment for shear material, when making this kind of accessories, the corresponding hardness is adjusted according to the thickness and texture of the shear plate.
Generally speaking, its hardness range should be kept between 60-90 degrees. It is also necessary to pay attention to the reasonable selection of the rubber ring size. The rubber ring size is mainly based on the size of the blade, according to the size of the blade to determine the size of the inner diameter. When using metal slitter equipment to process the sheet, select the appropriate retreat rubber ring according to the thickness of the sheet, which can ensure the appearance of the finished product is flat and surface quality.
There is a metal slitting machine equipment, known as the board type rejection, the current human door to use the rejection board is more hard texture of bakelite, red dyed wood, etc., the surface will be accompanied by a layer of anti-scratch material. This kind of rewinding method is mostly used for thin plate multi-specification small specification small specification slitting or the thickness of the plate village is not uniform and other finished products slitting.
