Split-flow slicing device and method for thermal composite material belt

The invention discloses a thermal composite material belt shunting slicing device and method, and the device comprises a first cutter mechanism, a shunting mechanism, a first vacuum belt assembly, a second cutter mechanism, a suck-back vacuum belt assembly, a second vacuum belt assembly, and a third cutter mechanism. The first cutter mechanism, the first vacuum belt assembly and the second cutter mechanism sequentially form a main machining channel from input to output, and the first cutter mechanism, the suck-back vacuum belt assembly, the second vacuum belt assembly and the third cutter mechanism sequentially form an auxiliary machining channel from input to output. The flow dividing mechanism is arranged between the input end of the first vacuum belt assembly and the input end of the suck-back vacuum belt assembly. According to the invention, a pole piece diaphragm combined material belt can be divided into two paths and more paths are arranged, so that the pole piece diaphragm combined material belt is re
