movement of the two support frames close to each other to drive the loop bar to move to clamp and install the winding drum, the dismounting process of the whole winding drum is simple and easy to operate, time and labor are saved, when the winding drum after being wound is taken down, the second spring loses the limit to drive the placing plate to reset so as to drive the motor and the speed reducer to reset, at the moment, the first spring loses the limit to drive the support frames to move upwards to drive the stand columns to move along with the support frames, the stand columns drive the sliding blocks to drive the moving plate to move upwards to separate the first contact from the second contact, so that the electromagnetic coil is powered off, at the moment, the first restoring spring loses the limit force to drive the T-shaped plate to reset, the pulling force of the T-shaped plate to the first pulling rope is reduced, the pulling force of the first pulling rope to, thereby pulling second stay cord makes its motion to the right drive the rotation of second rolling pole, second rolling pole drives the clockwise rotation of second helical gear, thereby drive first helical gear and rotate, first helical gear drives first rolling pole and rotates the partly rolling that pulls out before with first stay cord and reset, simultaneously in stopper motion to the right, the pulling force to the third stay cord reduces, thereby the third is replied the spring and is lost the restriction and drive the movable rod and reset and drive third contact and the separation of power contact, thereby make the controller outage, accomplish whole rolling process.

The winding device can automatically wind the fuse and has an automatic cutting function after the wound fuse reaches the rated weight, thereby saving a large amount of time and labor compared with the traditional manual operation, and the winding drum is convenient to mount and dismount, saves time and labor, can adjust the tension of the fuse, ensures that the winding process is stably carried out, effectively solves the problems of untight winding or breaking of the fuse caused by poor tension of the traditional manual winding control, and is worthy of popularization and use.
