The pay-off stand body 200 mainly comprises a pay-off stand base 210, an upright column 220 and a conduction bracket 230, wherein the pay-off stand base 210 and the conduction bracket 230 are respectively and fixedly arranged at two ends of the upright column 220, and the pay-off stand body 200 is in an inverted I shape. The pay-off stand body 200 is disposed at one side of the wire reel device 100, and the magnet wire 130 is drawn out from the wire reel device 100 and transferred through the conductive bracket 230.
The conducting support 230 is provided with a plurality of guide wheels for guiding the transmission of the magnet wire 130. Preferably, the guide wheel is made of nylon material, not metal material in the prior art, and the nylon material makes the surface of the guide wheel softer, so as to ensure that the electromagnetic wire 130 does not damage the paint film in operation.
Further, the bottom of the end of the conducting support 230 near the wire coil device 100 is provided with a guide sleeve 240 perpendicular to the conducting support 230, which limits the circumferential freedom of the magnet wire 130 and protects the magnet wire 130 from unnecessary damage.
The conductive path of magnet wire 130 is drawn from wire coil assembly 100, through guide sleeve 240, and further to the guide wheel.
The utility model discloses creative has set up the tensioning guide pulley, and the stand 220 side is provided with the slide along vertical direction, and tensioning guide pulley and stand 220 are along slide sliding connection, and extension spring 270 is connected along vertical direction both sides to the tensioning guide pulley.

Magnet wire 130 passes through the guide pulley and the tension pulley. When the winding machine drives the magnet wire 130 to move, the magnet wire 130 is stressed differently at different positions, which easily causes the magnet wire 130 to deform or the wire diameter to become smaller due to uneven stress, in this embodiment, the magnet wire 130 passes through the tensioning guide wheel, the extension spring 270 connected to the tensioning guide wheel plays a role in buffering, and when the stress changes, the extension spring 270 correspondingly moves up and down to enable the magnet wire 130 to be stressed uniformly.

Furthermore, the number of the guide wheels is three, the circle centers of the guide wheels are on the same horizontal line, and the guide wheels are respectively a first guide wheel 251 and a second guide wheel 252 which are positioned at two ends of the conduction bracket 230, and a third guide wheel 253 which is positioned at the central position, and the central position of the conduction bracket 230 is a position fixedly connected with the upright column 220; the magnet wire 130 is led out from the wire coil device 100, passes through the guide sleeve 240, and sequentially passes through the first guide wheel 251, the first tensioning guide wheel 261, the third guide wheel 253, the second tensioning guide wheel 262 and the second guide wheel 252. The magnet wire 130 is transmitted at intervals between the guide wheel and the tensioning guide wheel, so that the conduction path of the magnet wire 130 is increased, and the continuous tightening of the magnet wire 130 is facilitated; the stress generated in the transmission process of the electromagnetic wire 130 can be effectively buffered by the matching of the tensioning guide wheel and the extension spring 270, so that the stress of the electromagnetic wire 130 is uniform, and the deformation or the reduction of the wire diameter of the electromagnetic wire 130 is avoided.

The increased number of guide wheels further increases and defines the conduction path of the magnet wire 130, so that the conduction control of the magnet wire 130 is more accurate, and the magnet wire 130 is prevented from being separated from the pay-off rack in the conduction process.
Further, the electromagnetic wire 130 is vertically crossed and conducted when being conducted between the adjacent guide wheels and the tension guide wheel, and the conducting path is in an S shape, so that the tension force is increased and the conducting path is increased.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
