The winding equipment comprises a supporting table, a discharging opening is formed in the top of the supporting table, T-shaped supporting plates are fixedly installed on the two sides of the discharging opening, U-shaped containing grooves are formed in the tops of the T-shaped supporting plates, connecting holes are formed in one sides of the bottoms of the U-shaped containing grooves, and the connecting holes are communicated with the discharging opening. And a connecting block is clamped in the connecting hole, a first electric roller is rotationally installed at the bottom of the U-shaped containing groove, a first limiting hole is formed in one side of the connecting hole, and a convex limiting sliding block is fixedly connected to one side of the connecting block. After a U-shaped connecting rod and two inserting rods are taken out of an L-shaped clamping groove and an inserting groove correspondingly, then the L-shaped connecting rod is moved downwards, the L-shaped connecting rod moves downwards to
