Cold rolled thin plate unwinding leveling longitudinal cutting winding production line This series of production lines is used to unwind, longitudinally cut and coil metal coils of different specifications into coils of the required width size through unwinding, longitudinal cutting and slitting, and winding, providing raw materials for various processes such as rolling, cold bending, pipe making, and stamping production lines. Suitable for processing various metal sheets such as cold-rolled sheet, galvanized sheet, color coated sheet, stainless steel sheet, silicon steel sheet, aluminum sheet, etc. Widely used in metal sheet processing industries such as automobiles, containers, household appliances, food, packaging, and building materials. This series of production lines is equipped with a feeding trolley → an unwinding machine → a feeding device → a traction leveling machine → a transition bridge → a correction device → a longitudinal shearing machine → an edge wire machine → a material table and tail pressing device → a transition bridge → pre separation → a tension station → a feeding mechanism → a slitting shear → a turning roller group and feeding plate → a winding machine → an unloading trolley. The maximum operating speed of this series of production lines is 120 meters per minute& nbsp; Main technical parameters: Model ZSL-0.8 x Board Width ZSL-1.2 x Board Width ZSL-2 x Board Width ZSL-3 x Board Width ZSL-4 x Board Width Machinable Width mm1300, 1600, 1300, 1800, 1300, 2000 Machinable Board Thickness mm0.30-0.800.4-1.205-2.00.6-3.0-1.01.0-4.0 Production line speed m/min 80, 12070, 100 uncoiling weight t10, 15, 20 longitudinal cutting strips MAX 20 longitudinal cutting accuracy mm/m ＜ ± 0.5 ＜ ± 0.5 ＜ ± 0.5 ＜ ± 0.5 The above parameters are standard models and can be customized according to customer requirements& nbsp; ◆  The overall design structure is reasonable, the shape is compact, the precision is high, the efficiency is high, and the adjustment is flexible and convenient ◆  The frame is made of welded steel plates, annealed, and processed by a CNC machining center to ensure high strength and precision; The manufacturing process of the whole machine strictly follows the mechanical design specifications, and the material of the longitudinal cutting machine blade shaft is made of bearing steel 42CrMo ◆  The working shaft support of the whole machine adopts heavy-duty bearings, combined with advanced lubrication system, which has a long service life; Whole line PLC control, touch screen display and operation, high degree of automation ◆  All electrical components are selected from high-end foreign brands, and mechanical accessories are from well-known domestic brands& nbsp;
