Pole piece infrared hot air drying system

Abstract

The invention discloses a pole piece infrared hot air drying system. The pole piece infrared hot air drying system comprises an unwinding pattern assembly, a hot roller pattern assembly, a drying furnace pattern assembly, a driving pattern assembly and a winding pattern assembly, wherein the unwinding pattern assembly is provided with an unwinding rectification assembly, an unwinding swinging roller and an unwinding pressing belt platform assembly; a pole piece base band sequentially passes through the unwinding rectification assembly, the unwinding swinging roller and the unwinding pressing belt platform assembly and then enters the hot roller pattern assembly; the hot roller pattern assembly is provided with multiple hot rollers; the pole piece base band sequentially passes through each hot roller and then enters the drying furnace pattern assembly; furnace rollers are arranged up and down in parallel in a box of the drying furnace pattern assembly; multiple infrared lamps are arranged between the furnace rollers; a hot air circulation structure and a cooling circulation structure are also arranged at one side of the box; and the pole piece base band enters the driving pattern assembly sequentially through the furnace rollers and then enter the winding pattern assembly. The pole piece infrared hot air drying system has the beneficial effects that the pole piece base band is pretreated by using the hot roller pattern assembly and then enters the thermostatic controlled drying furnace pattern assembly; and the pole piece infrared hot air drying system meets the technological requirements of pole piece heating equipment on fast operation speed, fast temperature rising, high uniformity and short heating time.
