When the wire coil winding mechanism is used, wire coils to be used are placed on the upper portion of the base 1 according to actual requirements, the wire coils are placed on the upper portion of the base 1 in rows, the number of the placed rows is the same as that of the loading cavities 14 in the wire body 6, and the number of the wire coils in one row is the same as that of the bearing plates 13 in the wire coil winding mechanism, so that one bearing plate 13 can correspond to one wire coil.

The parameters required in the work are set through the background electric control system, so that the parts in the whole device can work according to the set program, intelligent operation is realized, and manual operation is not needed.

When the loading is needed, the moving gear in the bottom plate 10 rotates and then moves on the linear rack in the side plate 9, so that the loading mechanism is driven to move towards one end of the twisting body 6 until the end part of the bearing plate 13 enters the loading cavity 14 and is positioned below the inner wire coil. The bottom of the wire coil is contacted with the top of the bearing plate 13, the electric telescopic column 20 on the upper part of the conveying plate 30 extends to drive the moving rod 16 to horizontally move towards one end, and in the process that the moving rod 16 moves towards one end, the fixing plate 19 drives the locking plate 17 to rotate around the intermediate shaft 18. After the locking plate 17 rotates, the bottom end of the locking plate abuts against the top end of the wire coil on the upper portion of the bearing plate 13, and then the wire coil is limited, so that the wire coil can be stably limited on the upper portion of the bearing plate 13, and the wire coil is not prone to shaking and falling.

After the wire coil moves to the top of one end of the base 1 close to the twisting body 6, the driving motor 2 in the wire coil mechanism drives the speed reducer 29 to operate, and then the first rotating rods 11 at the two ends of the speed reducer 29 are driven to rotate. In the process of rotating the first rotating rod 11, the driving gear 12 at one end is driven to rotate, the driving gear 12 drives the fan-shaped rack to rotate towards the lower part of one end of the twisting body 6, so that the fan-shaped toothed plate 3 is driven to overturn downwards until the end part of the bearing plate 13 is perpendicular to the base 1, and a wire coil on the upper part of the bearing plate 13 is parallel to the base 1 and contacts with the base 1 to stop rotating.

After the empty wire coil is taken out and placed on the upper part of the base 1, the driving motor 2 drives the sector toothed plate 3 to rotate back to the original position. The bottom plate 10 is then moved over the side plates 9 to the end remote from the cable 6 and is stopped after it has moved over a new coil at one end. The sector toothed plate 3 rotates downwards until the end of the bearing plate 13 is perpendicular to the base 1 and abuts against one end of a new wire coil. The electric telescopic column 20 drives the locking plate 17 to rotate, and the locking plate 17 limits and fixes the wire coil, so that the wire coil is not easy to fall off. After the wire coil is fixed, the sector toothed plate 3 rotates upwards, and then the wire coil is driven to rotate upwards to be in a vertical state. The wire coil is driven by the wire coil feeding mechanism to move towards one end of the wire coil body 6 until a new wire coil enters the empty loading cavity 14, the locking plate 17 rotates to be separated from the top of the wire coil, and after the wire coil is fixed in the loading cavity 14, the wire coil feeding mechanism moves towards the other end to drive the bearing plate 13 to be separated from the loading cavity 14 and the wire coil.

After a new wire coil is installed in one loading cavity 14, the twisting body 6 rotates to rotate the wire coils in other loading cavities 14 to be in a vertical state, and therefore a subsequent wire coil feeding mechanism can take out an empty wire coil conveniently. The upper disc mechanism takes out the empty discs, puts the empty discs on the base 1 in the positions where the new discs are moved and then the new discs in other rows are taken out and put in the loading cavity 14 in the twisting body 6. And the upper disc mechanism can take out all the empty discs in the reel body 6 and place the empty discs on the base 1, and can install new discs on the base 1 into the reel body 6.

After a new wire coil is installed in the loading cavity 14 in the wire reel body 6, the stepping motor 8 drives the driving wheel 7 at one end of the wire reel body 6 to rotate, and further drives the wire reel body 6 to rotate, so that an empty wire coil in the wire reel body 6 can be conveniently and quickly rotated to one side facing the wire coil loading mechanism, and the wire coil is kept in a vertical state. The empty coils can then be taken out in sequence and new coils can be conveniently and quickly and accurately mounted inside the loading chamber 14.

When the twisting body 6 rotates, the end plates 22 at the two ends rotate together with the twisting body, and a plurality of proximity switches 21 outside the end plate 22 at one side rotate together with the end plate 22. When the proximity switch 21 rotates to the bottom and the vertical plate 24 of iron is located in the detection range of the proximity switch 21, the proximity switch 21 starts to operate and transmits a signal to a background control system, and then the host PLC sends a signal instruction to the winch PLC. The winch PLC controls the hydraulic oil cylinder 23 and the brake 26 to operate, meanwhile, the stepping motor 8 stops rotating, the brake plate at the end part of the brake 26 is abutted to the end plate 22 under the driving of the hydraulic column, the end plate 22 is decelerated, and finally the rotation of the end plate is stopped. The guide block 25 is driven by the hydraulic oil cylinder 23 to move towards the positioning device 27, and finally the guide wheel 28 in the positioning device 27 is clamped in the guide block 25, so that the hinge body 6 can not rotate any more, and the position is stable. The guide block 25 and the brake 26 can carry out dual positioning on the reel body 6, the reel body 6 is high in stopping speed, accurate in positioning, high in precision after stopping, free of displacement and capable of fully guaranteeing the accuracy of the wire coil when the wire coil is taken and placed. The twisting body 6 can realize accurate positioning and complete braking; the problem of artifical location hank body 6 is solved, reach the effect of automatic positioning hank body 6.

After the wire coil in the loading cavity 14 is taken and placed, the brake 26 and the guide block 25 are separated from the end plate 22, the stepping motor 8 drives the wire winding body 6 to continue rotating, after the next proximity switch 21 on the side surface of the end plate 22 is triggered, the wire winding body 6 stops rotating again and is positioned, the wire coil in the wire winding body 6 can be taken and placed in sequence, disorder cannot occur, and accuracy is high.

In the using process, a worker can set relevant parameters in work through the host computer human-computer interface, the relevant parameters set by the host computer human-computer interface are transmitted to the host computer PLC and the side surface disc feeding PLC after being exchanged by the exchanger, and the host computer PLC transmits data to the twisting body PLC so as to realize the synchronization of the data parameters.
