[0002] The unwinding system is the part of the printing equipment used to store flexible roll materials, which can drive the flexible roll materials to be stably output for subsequent printing work; flexible roll materials refer to printing media that have certain flexibility and toughness and can be stored in rolls; when the printing media is output, it is necessary to consider whether its edges are skewed to ensure the printing quality, so the unwinding system also has to bear part of the correction function; in the past, the correction mechanism was usually a horizontally set connecting rod mechanism, and the movable rod of the connecting rod mechanism was used as a vertical swing rod to act on the edge of the horizontally flowing printing medium to achieve correction. The horizontally set correction mechanism requires a large area for layout, which makes the site requirements of the unwinding system high; and the vertical swing rod of the correction mechanism is in line contact with the printing medium, and there is a slipping situation, and the correction effect is difficult to guarantee. Summary of the invention

The photoelectric switch monitors the edge of the flexible rolled material in real time and provides an electrical signal for driving the deflection-correcting push rod. One end of the vertical swing rod is vertically hinged to one side wall panel, and the other end passes through the other side wall panel. The deflection-correcting push rod is installed on the outside of the other side wall panel. The telescopic end of the deflection-correcting push rod presses upward against the lower side of the part of the vertical swing rod that passes through the wall panel. The telescopic end of the deflection-correcting push rod vertically retracts and drives the vertical swing arm to swing vertically. The flexible rolled material released from the unwinding roller flows forward and passes around the upper side of the vertical swing rod.

[0027] Working principle of this embodiment: Figure 3 , the unwinding roller 2 releases the flexible rolled material 0 and conveys it to the vertical swing rod 31; the flexible rolled material 0 passes through the upper end of the vertical swing rod 31 and then passes through the photoelectric switch frame 331; the photoelectric switch 33 on the photoelectric switch frame 331 monitors the edge of the flexible rolled material 0 in real time; the deviation correction push rod 32 acts according to the monitoring situation of the photoelectric switch 33, driving the vertical swing rod 31 to swing vertically; See also Figure 5 When the photoelectric switch 33 detects that the edge of the flexible roll material 0 exceeds the photoelectric switch 33 and blocks the light connection of the photoelectric switch 33, the telescopic end of the correction push rod 32 extends outward to push the right end of the vertical swing rod 31 to rise; when the right end of the vertical swing rod 31 is higher than the left end of the vertical swing rod 31 (the left end of the vertical swing rod 31 is hinged to the wall panel 1), the flexible roll material 0 slides to the left as a whole, causing the flexible roll material 0 at the photoelectric switch 33 to also shift to the left synchronously until the light of the photoelectric switch 33 is connected again; the correction push rod 32 stops outputting.

[0028] The tension roller 41 brings the flexible rolled material 0 that has passed through the tension roller 41 down; because both ends of the tension roller 41 have synchronous gears 411 that mesh with the vertical rack 421; the tension roller 41 has the same effect on the flexible rolled material 0 in the width direction, and can give the flexible rolled material 0 tension, so that the flexible rolled material 0 fits the upper end surface of the vertical swing rod, which can ensure the correction effect of the vertical swing rod 31; in addition, during the vertical swinging process of the vertical swing rod 31, the tension roller 41 also synchronously performs adaptive rise and fall, which is also to ensure that the correction action of the vertical swing rod 31 is successfully completed.
