The slitting line is a name for the metal slitting device. It is suitable for longitudinal shearing of metal strips and rewinding the slit strips into rolls. It consists of unwinding, feeding positioning, slitting and slitting, and coiling. Today we mainly look at the structure type of HR Slitting Line.
The equipment composition generally includes an uncoiler, a guiding device, an unwinding tension device, a cutting head shearing, a feeding table, a looper, a disc cutter, a guide roller, a machine transfer roller, an inlet clamping device, and so on.
1. Single inlet looper slitting:
This type of slitting is provided with a looper in front of the shearer. The method of feeding the strip into the inlet loop is in the form of a central drive unwinding, a tensioning unwinding, a floating roller control unwinding method, and the like. Realize micro tension or zero tension shear to avoid slippage of the cutting edge.
2. Single outlet looper slitting:
This type of slitting is provided with a looper after the shearing, and the sheared strip is pushed by the shearing machine into a tensionless looper between the shearing machine and the tensioning device. For thin strips, an inlet edge guide system may be required to ensure stable coil unwinding during shearing. Due to the provision of the outlet looper, the strip can freely flow out of the cutting edge, avoiding the wear of the strip on the cutting edge under tension and affecting the life of the cutting edge.
3. Double looper slitting:
The double looper longitudinal shear combines both the inlet looper slitter and the outlet looper slitter. After the strip enters the shearing machine after leaving the coiler, a free looper is fed by the uncoiler or a pinch roller device or a tensioning device, and the strip after being cut leaves the shearer and is sent to another Loop and then enter the tensioning device. With this form of slitting, the slitter is only used to split the strip, so it eliminates the possibility of the strip slipping at the edge of the scissors. This method is suitable for the shearing of thin flexible strips.
HR Slitting Line has the characteristics of convenient operation, high cutting quality, high material utilization rate and stepless speed regulation of cutting speed. It is suitable for tinplate, silicon steel sheet, aluminum strip, copper, stainless steel sheet, galvanized sheet, etc. It is widely used in transformers, motors, home appliances, automobiles, building materials, packaging and other industries.
