Abstract

The invention discloses a novel large slitting system and process capable of reducing winding exposed ribs. The novel large slitting system capable of reducing the winding exposed ribs comprises an unwinder, a flattening system, a slitting system, winding pressure control systems and winding cores, wherein the flattening system comprises first passing rollers and a flattening roller. the arc height of an arc between two tangent points of a diaphragm on the flattening roller is 5 to 15mm, and the wrap angle is 20 to 45 degrees; the slitting system comprises a cutter roller, a speed metering roller and second passing rollers; the winding pressure control systems are winding compression rollers; the winding compression rollers comprise inner cores and rubber layers wrapping the inner cores; the diameter of each winding compression roller is 100 to 120 mm; the surface of each rubber layer is provided with an outwards-extending double-helix structure; and the winding compression rollers arein rolling connection with the winding cores. The process comprises the following steps of applying the large slitting system; setting the winding speed of the winding cores to be 80 to 120 m / min, and setting the winding tension to be 5 to 8 N / m; setting the unwinding tension to be 1 to 2 times of the winding tension; and setting the winding pressure to be 1.5 to 4 times of the winding tension. Through the novel large slitting system and process capable of reducing the winding exposed ribs provided by the invention, the winding exposed ribs are obviously reduced, and the high one-time yield of large slitting winding is achieved.

Description

technical field [0001] The invention relates to the technical field of diaphragms, in particular to a novel large slitting system and process for reducing wind-up tendons. Background technique [0002] The large slitting machine is used to slit and wind the base film produced by the main line. The process design of the large slitting will directly affect the final winding effect of the separator. Improper process design will lead to violent ribs when the diaphragm is rolled, and serious dead wrinkles will appear at the position of the ribs (it cannot be completely flattened after a certain tension is applied), and the defect of the diaphragm will not only lead to subsequent The problem of leakage of coating occurs during ceramic coating, and at the same time, violent tendons or dead wrinkles will occur when the final product is cut, and battery manufacturers may experience equipment failure and poor product winding when the battery is wound. The structural difference of the...
