Abstract

The invention provides a roll changing device and method for a battery material belt and a die-cutting machine, relates to the technical field of battery production, and aims to at least solve the problems that due to the fact that a torque control mode is adopted in the related technology, powder falls off from the battery material belt, and the operation accuracy of the die-cutting machine is affected. The roll changing equipment comprises a first unwinding roller and a second unwinding roller, the first unwinding roller is used for unwinding a battery material strip, and the second unwinding roller is used for unwinding a standby battery material strip; the reel changing device is used for pulling the material belt of the first unwinding roller to move; and the control device is used for responding to a received roll changing signal, controlling the roll changing device to pull the tail part of the battery material belt on the first unwinding roller to be jointed with the head part of the battery material belt on the second unwinding roller according to a fixed movement speed, and controlling the roll changing device to cut off the battery material belt on the first unwinding roller.
