Notching scrap no load drainage system and scrap drainage method

摘要

An object of the present invention is to provide a no-load discharge system for notched scrap, which includes: a scrap pipe 10 disposed under a notched mold for forming a tab on an electrode plate during a secondary battery manufacturing process; A blade assembly that is rotatably mounted in the scrap discharge space inside the scrap pipe 10 to partition the scrap discharge space of the scrap pipe 10 into an upper atmospheric pressure discharge space 10DC and a lower vacuum pressure discharge space 10VC (20); including, the blade assembly 20 is a rotary drive shaft 22 rotatably coupled to the scrap pipe (10); and a plurality of rotary blades 24 coupled to the outer circumferential surface of the rotary drive shaft 22 so as to be radially disposed on the periphery of the rotary drive shaft 22 .
