A processing device for producing signal cables for rail transit according to claim 5, characterized in that: The surface cleaning mechanism (20), the cable combing and guiding mechanism (30), and the intersection of the heating box (60) and the frame (10) are all provided with a lifting assembly (70); The lifting assembly (70) comprises a hydraulic lifting column (710) installed on the top of the frame (10) and a mounting plate (720) installed on the lifting end of the hydraulic lifting column (710).

7. The processing method of a processing device for producing a signal cable for rail transit as claimed in claim 6, characterized in that: The following steps are involved: S1: When twisting a plurality of single-wire cables, the first electric telescopic rod (220) and the third electric telescopic rod (320) on the first layout plate (210) and the second layout plate (310) are in a retracted state, so that the first layout plate (210) and the second layout plate (310) are brought closer to each other, and then the single-wire cables are respectively passed through the gap between the active roller brush (272) and the driven roller brush (273), and passed through the gap between the upper guide roller (350) and the lower guide roller (360). The single-wire cable passes through the gap between the upper guide roller (350) and the lower guide roller (360), and then enters the limiting hole formed on the positioning seat (560) and is fixed by the locking bolt (570). When the single-wire cable passes through the roller brush assembly (270), impurities on the surface of the single-wire cable can be effectively cleaned. Secondly, when the single-wire cable enters between the upper guide roller (350) and the lower guide roller (360), the electric heating rod (380) embedded therein can heat the single-wire cable to soften it, thereby facilitating winding. S2: When the single-wire cable passes through the heating box (60), the electric heating pipe (610) in the heating box (60) and the hot air blower (620) at the bottom maintain a certain temperature in the inner cavity of the heating box (60), thereby heating the passing single-wire cable and further softening it; S3: Then, the driving pulley (510) is turned on, and the driving pulley (510) drives the driven pulley (530) to rotate through the transmission belt (540), thereby driving the twisting drum (550) to rotate, thereby realizing the twisting function of the single-wire cable connected to the positioning seat (560); S4: When temporarily wiring or winding up a single-line cable, the first electric telescopic rod (220) and the third electric telescopic rod (320) on the first wiring plate (210) and the second wiring plate (310) are in an extended state, and the first limiting plate (240) and the second limiting plate (370) on the outer side walls of the first wiring plate (210) and the second wiring plate (310) are in contact with each other. At this time, the plurality of first wiring plates (210) and the plurality of second wiring plates (310) are in the same straight line, and then the cables to be wired are respectively passed through the filling roller brush assembly (270) and the cable combing guide mechanism (30), and are wound around the winding drum (430); S5: At this time, the driving shaft (420) is turned on, and the driving shaft (420) drives the winding drum (430) to rotate, and the winding drum (430) winds up the cable wound on the outer wall of the winding drum (430), so that the wiring cable is kept in a taut state, and at the same time, the wiring height is adjusted by the hydraulic lifting column (710) in the lifting assembly (70).
