Abstract

The invention discloses an unwinding device for insulating paper, which comprises a support, a paper roller, two support seats, a driving roller, a driven roller, a driving motor and a driving chain. The advantage of the unwinding device for insulating paper of the present invention is that it has a driven roller connected with a movable block, and the movable block is connected with a spring, which can effectively prevent the insulating paper from being damaged while ensuring a certain tension of the insulating paper. Torn off; also with studs, by adjusting the length of the studs, the elastic force of the spring can be adjusted more conveniently, so that it can adapt to various specifications of insulating paper.

Description

technical field [0001] The invention relates to the field of transformer manufacturing, more precisely, it relates to an unwinding device for insulating paper. Background technique [0002] In the process of transformer production, a large amount of insulating paper is used. In order to make these insulating paper fit better on the silicon steel sheet, when removing the insulating paper from the paper roll, the paper roll must be kept at a certain tension; use The unwinding device in the prior art is easy to tear off the insulating paper, which seriously affects the production efficiency of the transformer. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a driven roller with a movable block connected with a spring, which can effectively prevent the The insulating paper is torn off; there is also a stud, by adjusting the length of the stud, the elastic force of the spring can be adju...
