The vertical plate 2 is provided with a push-out cylinder 4 through a fixing frame, a cylinder rod of the push-out cylinder 4 is positioned at the tail end of the push-out shaft 10, the cylinder rod of the push-out cylinder 4 is not connected with the push-out shaft 10 and is provided with a gap, the push-out shaft 10 can rotate freely, and when the cylinder rod of the push-out cylinder 4 extends, the push-out shaft 10 is pushed to move towards the head end.

As shown in fig. 3 and 4, the fixed winding head 5 is fixedly connected to the head end of the winding shaft 9, and the pushing block 6 is fixedly connected to the head end of the pushing shaft 10. The end face of the fixed winding head 5 is provided with an embedded groove 51, in the embodiment, the embedded groove 51 is cross-shaped, the pushing-out block 6 is corresponding to the embedded groove 51 in shape and is arranged in the embedded groove 51 to form clearance fit with the fixed winding head 5, and the fixed winding head 5 and the pushing-out block 6 are in sliding connection in the axial direction of the winding shaft 9. Thus, when the fixed winding head 5 rotates, torque can be transmitted to the ejector block 6 through the insertion groove 51 to rotate synchronously. When the cylinder rod of the push-out cylinder 4 is extended, the push-out shaft 10 is pushed, and the corresponding push-out block 6 comes out of the insertion groove 51 in an axially forward movement.

Four axial winding columns 7 and four axial guiding columns 12 are also arranged in the embedding groove 51 of the fixed winding head 5, and the axial winding columns 7 and the axial guiding columns 12 are arranged in a direction parallel to the winding shaft 9. The four axial guide columns 12 are fixedly arranged, the four axial winding columns 7 are connected to the adjusting slide blocks 52 of the embedded grooves 51, the two axial winding columns 7 are fixed on one adjusting slide block 52, the two adjusting slide blocks 52 are arranged to be distributed in a central symmetry mode by the winding shaft 9, and the two adjusting slide blocks 52 are connected at intervals by the adjusting screw rods 53 on the side edges of the fixed winding head 5. Four axial winding posts 7 are used as vertexes, connecting lines form a first rectangle, four axial guiding posts 12 are used as vertexes, connecting lines form a second rectangle, the long sides of the first rectangle are perpendicular to the long sides of the second rectangle, and the distance between the axial winding posts 7 and the winding shaft 9 is not smaller than the distance between the axial guiding posts 12 and the winding shaft 9. Four axial winding posts 7 and four axial guide posts 12 all run through the pushing block 6, so set up four bar holes 61 and four guide through holes 62 on the pushing block 6, the axial winding post 7 wears to locate in the bar hole 61, the length direction of bar hole 61 is the moving direction of adjusting the slider 52 promptly, the axial guide post 12 wears to locate in the guide through hole 62.
