| 放卷装置主要包括膜卷放置架、膜卷制动器、摆辊、EPC装置、三角板叠加辊等组成，以一定张力放卷并把薄膜折叠起来。 Rewinding device mainly consists of film coil placement frame, film coil brake, pendulum roll, EPC device, triangle overlay roll, etc. Rewinding with a certain tension and folding the film. 张力控制先由圆周编码器检出薄膜速度，由位置传感器检出摆辊位置，再由磁粉制动器扭矩控制摆辊在一定位置。薄膜张力由摆辊的汽缸供给，通过调整压力阀进行张力调整，张力一般设置10~40N。 In tension control, film speed is detected by circular encoder, swing roll position is detected by position sensor, and swing roll position is controlled by magnetic powder brake torque. The film tension is supplied by the cylinder of the swing roller. The tension is adjusted by adjusting the pressure valve. The tension is generally set to 10 ~ 40N. 摆辊能使制袋的间歇进给转用卷筒连续卷出，橡胶辊只能向薄膜卷出方向转动，防止停机时回卷。 The pendulum roll can make the intermittent feeding drum of bag making roll out continuously. The rubber roll can only rotate in the direction of film roll out to prevent rollback during shutdown. |
