[0027] Working principle: The motor 3 drives the screw rod 5 to rotate so that the movable platform 8 moves; the heating wire set outside the vertical rod 11 passes through a pair of horizontal clamping rollers 27, a pair of vertical clamping rollers 28, two rollers 30, three pairs of horizontal rollers 12, and a pair of vertical rollers 17 in sequence and is wound on the winding shaft 7. The winding shaft 7 is driven to rotate by the headstock 2 and the movable platform 8 is moved so that the heating wire is spirally wound on the winding shaft 7; the winding shaft 7 is lifted by the upper clamping block 25 and the lower clamping block 21. When the hot wire is wound around the lower clamping block 21, the sensor 9 detects the moving platform 8 and drives the small cylinder 19 to drive the lifting plate 20 to descend and release the support on the L rod 22, so that the front end of the L rod 22 rises under the action of the tension spring 18, thereby preventing the upper clamping block 25 and the lower clamping block 21 from interfering with the winding; the electric push rod 14 drives the U-shaped plate 16 and the clamping roller 34 forward to provide accompanying support for the winding shaft 7 and reduce vibration; the cylinder 32 drives the roller 30 forward and backward to keep the heating wire taut.

[0028] When processing the heating wire, the device can control the moving speed of the movable table 8 and the rotation speed of the winding shaft 7. The heating wire can be formed in one time according to the design parameters. The pitch, spiral middle diameter and bridge position are adjustable. The parameters are precisely controlled and adjustable by the equipment. The pitch is uniform, so that the error between the resistance parameters of the heating wire and the designed resistance parameters is small. There is no need to stretch the pitch in sections again after the heating wire is densely wound, as in the traditional winding process, thereby improving production efficiency.
