However, this winding structure has two problems: firstly, utilize numerical control programming's mode, lead to the wire drawing machine when receiving line to the wire drawing section of thick bamboo of unidimensional, all need operating personnel to reprogram to operating personnel's work complexity has been increased. Secondly, the distance detection mode is realized through a proximity switch, and the detection accuracy can be ensured only when an obvious distance difference exists between the wire rewinding part and the side wall of the wire rewinding cylinder; the wire drawing cylinder can not be fully drawn in order to reserve a detection space in the wire drawing process, and the utilization rate and the winding effect of the wire winding cylinder are further reduced.

The working principle of the invention is as follows: when the enameled wire is produced, a wire drawing machine 1 firstly draws a thick copper wire to enable the thick copper wire to extend to a thin wire with a specified outer diameter. Before the wire drawing machine 1 is used, the zero position of the zero position part 13 is adjusted according to the wire drawing machine, namely when the wire arranging rod 8 is positioned at the wire collecting center position of the wire drawing machine 1, the positions of the positioning rod 12 and the zero position part 13 in the horizontal direction are flush. After the parts 13 are positioned, the transverse positions of the limit switches 14 on the two sides are respectively adjusted according to the length and the installation position of the wire drawing cylinder; so that when the winding displacement rod 8 is moved to the edge of the drawing tube, the positioning rod 12 triggers the limit switch 14. When the limit switch 14 is adjusted, the screw rod 16 can be driven to rotate by rotating the operating handle 18, so that the limit switch 14 is driven to transversely move on the screw rod 16, an operator can accurately position the limit switch 14 by using the operating handle 18 with digital scales, and the detection effect of the invention is improved.
When the wire drawing machine 1 is used, the transmission belt 10 drives the wire arranging rod 8 to do reciprocating transverse movement through the driving seat 9, so that a drawn copper wire is uniformly wound on the wire drawing cylinder. When the winding displacement rod 8 moves, the positioning rod 12 on the driving seat 9 is driven to move in a matching manner, the positioning rod 12 triggers the limit switch 14 when the winding displacement rod 8 moves to the edge position of the wire drawing cylinder, and the winding displacement rod 8 is controlled to return after the limit switch 14 triggers, so that the winding displacement rod 8 can realize reciprocating motion under the action of the limit switches 14 on the two sides, and the winding displacement rod 8 is effectively prevented from exceeding the wire drawing cylinder.

When wire drawing cylinders of different specifications need to be replaced temporarily, the operator can directly utilize the position switch 14 to replace numerical control programming to realize reciprocating control on the wire arranging rod 8, so that the workload caused by reprogramming is prevented from being increased, and the temporary treatment of the operator is facilitated.
After the copper wire is rolled by the wire drawing cylinder, the wire drawing cylinder is unloaded from the wire drawing machine 1 by an operator and then is connected into the conveying mechanism again, so that the conveying mechanism can sequentially send the copper wire into the baking oven 2 and the enamelling machine 3 for treatment and then is rolled by the wire rewinding machine 4, and the production of enamelled wires is realized. When the oven 2 and the enamelling machine 3 process the copper wire, the copper wire sequentially passes through the tensioning group at the wire inlet end of the oven 2, the enamelling machine 3, the tension sensing mechanism 6 at the wire outlet end of the enamelling machine 3 and the tensioning group at the wire outlet end of the enamelling machine 3 along the wiring direction.

When the copper wire passes through the oven 2 and enters the tension sensing mechanism 6, the copper wire passes through the first guide wheel 21 from the lower part and is led out from the upper part, so that the copper wire can support the first guide wheel 21, and the sensing frame 19 is kept in a horizontal and free floating state. When the copper wire jumps, the induction frame 19 can float up and down along with the jumping of the copper wire, so that the rotating gear is driven to rotate; the rotating gear, upon rotation, triggers the angle sensor via the mating gear 26 so that the angle sensor can sense the runout amplitude of the copper wire. When the jumping amplitude of the copper wire exceeds the floating threshold value, the tension of the copper wire is insufficient, and then the push rod 39 drives the swinging rod 37 to further rotate and strain the enameled wire, so that the jumping amplitude of the enameled wire is relieved.
When movable balancing weight 25 and fixed balancing weight 24 are installed, operating personnel can also be through changing the pressure of exerting pressure of the first leading wheel 21 of movable balancing weight 25 lateral position adjustment in the sliding tray to the copper line, guarantee promptly the timely reflection of first leading wheel 21 one end after the copper line broken string, avoid first leading wheel 21 to exert pressure too big the excessive straining that leads to the fact the enameled wire to the enameled wire simultaneously, and then guarantee the transport stability to the enameled wire.
After the enameled wire is processed and formed by the enamelling machine 3, the surface of the enameled wire is oiled by the lubricating oil coating device and then is sent to the wire rewinding machine 4, and a wire rewinding motor on the wire rewinding machine 4 drives a wire rewinding cylinder to rotate to rewind the enameled wire. During the winding process, the enameled wire firstly passes through the second guide wheel 29 and the pressing felt 33 on the wire breaking clamping mechanism 7 and then enters the corresponding wire winding cylinder. The enameled wires can be limited and guided through the second guide wheel 29, so that the intervals among the enameled wires are kept consistent; through the cooperation of walking line passageway 32 between the adjacent spacing post 31 and compressing tightly felt 33, can form two ascending spacing to the enameled wire respectively to prevent the horizontal deviation of enameled wire when the broken string and break away from, the friction that forms between felt piece and the lower felt piece in the cooperation simultaneously alleviates the enameled wire along walking the drunkenness of line direction, and then realizes the tight effect of clamp to the enameled wire. When the enameled wire is broken, the induction frame 19 where the enameled wire is located directly drops due to the fact that the position of the induction frame is lost, the corresponding wire winding motor is controlled to stop after the rotating angle sensing the induction frame 19 exceeds the wire breaking threshold value, the phenomenon that the enameled wire on the wire winding drum is whipped around due to the rotation of the enameled wire is avoided, and the normal winding of the adjacent enameled wire is guaranteed. Meanwhile, the enameled wire positioned on the wire breaking clamping mechanism 7 is clamped after being broken, so that the enameled wire can be prevented from being separated from the routing channel 32 and falling into an adjacent wire collecting barrel, and the wire collecting stability of the adjacent enameled wire is further improved.
When the wire breaking clamping mechanisms 7 are installed, the wire breaking clamping mechanisms 7 are respectively installed on the wire rewinding machine 4 through the fixing frame 27, and the wire breaking clamping mechanisms 7 are in one-to-one correspondence with the wire rewinding cylinders, so that the enameled wires can extend downwards into the wire rewinding cylinders after passing through the wire breaking clamping mechanisms 7. After the fixing frame 27 is installed, the second mounting frame 40 and the third mounting frame 41 are respectively rotated, so that the second guide wheel 29 and the pressing felt 33 can be flush with the trend height of the enameled wire, and meanwhile, the positioning shaft 30 is rotated to enable the pressing felt 33 to be horizontally placed, so that the enameled wire can sequentially pass through the second guide wheel 29 and the pressing felt 33 in a linear state, and the conveying effect on the enameled wire is improved.
