The utility model discloses a theory of operation is:

firstly, a winding mode:

along with unreel motor's drive, the cable is followed the actinobacillus wheel and is emitted, clockwise around the wire wheel of advancing after, the coiling reaches the lead wire wheel of foremost (or last), then with anticlockwise at a plurality of pairs of lead wire wheels, wind down between the fine wheel of winding, again from last (or foremost) lead wire wheel of going up comes out, with clockwise around the line wheel after, with anticlockwise around the detection wheel, pass between fixed block and the roof pressure piece again, then clockwise around the take-up pulley of downside, then anticlockwise around the take-up pulley of upside, pass again between two leading wheels, wind on the take-up pulley after the winding of winding behind the winding ware.

Secondly, a control mode:

when the take-up motor is too fast, the tension of the cable is overlarge at the moment, the distance between the two tensioning wheels overcoming the spring force is reduced, the tension of the take-up cable is buffered, meanwhile, the cable between the upper wire guide wheel and the lower wire guide wheel on the vertical wire storage frame is pulled out, the height of the lower wire guide wheel is increased (the distance between the upper wire guide wheel and the lower wire guide wheel is reduced, the process of releasing the cable is reduced), the height of the balancing weight is separated from a balance point and is reduced, the fixed pulley is rotated, the angle sensor detects the angle change and sends the angle change to the electric control box, the electric control box controls the take-up motor to reduce the speed and take-up the cable, the pay-off motor also accelerates the pay-off, the height of the lower wire guide wheel is gradually reduced (the distance between the upper wire guide wheel is increased, the process of storing, the unwinding motor is not accelerated any more, and the stable operation is kept.

Similarly, when the speed of the take-up motor is too low, the angle sensor detects the change of the angle and sends the change of the angle to the electrical control box, the take-up motor starts to accelerate, and the unreeling motor decelerates until the take-up motor operates stably again.

Thirdly, replacing the take-up reel:

when the meter counter counts the preset length, the electric control box controls the current wire rewinding motor to stop, the other wire rewinding motor is started, the jacking cylinder ejects the wire, the jacking pressing block and the fixing block press the wire, then the wire is cut off and wound on the other wire rewinding disc to perform coiling. Loosening the screw of the take-up reel mounting frame which is completely taken up, detaching the front baffle, then pulling the rolled coil or take-up reel outwards, gathering the expansion block, easily taking down the coil or take-up reel, then mounting a new take-up reel, sleeving the front baffle on the rotating shaft, pushing the expansion block backwards, opening the expansion block until the rear end abuts against the rear baffle, tightly pushing the front baffle at the front end, screwing the screw, locking the positioning sleeve of the front baffle, and waiting for the next take-up.

The above description is only a preferred embodiment of the present invention, and various modifications and changes will occur to those skilled in the art.
