Abstract
The utility model relates a winding tension automatic control device which is characterized by comprising a rotation shaft, a support plate, a first bearing seat, a second bearing seat, a friction-free cylinder, a support, a swinging roller wheel and fixing shafts, wherein the first bearing seat and the second bearing seat are fixed on the support plate. The rotation shaft is arranged on the first bearing seat and the second bearing seat through bearing supports. The support is fixedly connected with the rotation shaft, and two fixing shafts are arranged in parallel mode and respectively fixed on the support. The fixing shafts are respectively sleeved with a winging roller wheel through the bearing supports. One end of a connection block is fixed on the rotation shaft, and the other end of the connection block is hinged with the piston rod end of the friction-free cylinder through a pin shaft. According to the winding tension automatic control device, through combination of machine and electricity, constant tension is achieved. An encoder is used to sense a rotation angle of the rotation shaft, and an unwinding motor is controlled and driven through electricity to accelerate or decelerate unwinding. A certain pressure is maintained through the friction-free cylinder, so an unwinding electrode sheet is enabled to be constant in the tension, and the tension control accuracy is high.
