& nbsp;& nbsp; The leveling machine has a reasonable layout, easy operation, high degree of automation, high production efficiency, high work accuracy, and moderate price. It can process various cold-rolled, hot-rolled coils, silicon steel plates, stainless steel plates, color plates, aluminum plates, as well as various metal plates after electroplating or coating. Widely used in metal sheet processing industries such as automobiles, agricultural vehicles, containers, household appliances, packaging, and building materials. This production line is mainly used for feeding carts, single and double support unwinding machines, longitudinal cutting machines, trimming machines, shearing machines, stacking devices, etc. It is also equipped with swinging intermediate bridges, traction devices, correction devices, CNC feeding and sizing devices, etc. between each machine. This production line is an automatic coil processing equipment that integrates machinery, electricity, liquid, and gas.  & nbsp; The rollers on the leveling machine have more layout options than ordinary leveling machines, which is conducive to reciprocating leveling and feeding; Each upper roller is equipped with a pressing transmission device and a detection device, which can adjust the relative position arbitrarily. Therefore, in addition to other leveling functions such as parallel and inclined pressing, the upper roller can also be arranged in a V-shape, which is convenient for reciprocating leveling of high-strength and explosive composite steel plates. Especially when the deformation of high-strength plates is large, it is more conducive to solving the problem of difficult feeding of the leveling machine. Moreover, the leveling machine also has a variable number of rollers correction method, which is beneficial for reducing power consumption and extending the service life of the machine.
