[0032] Coiled material refers to sheet material, such as steel or aluminum coils, that has been rolled into a coil for easy transportation and storage. On a slitting and coiling line, the coil undergoes steps such as unwinding, flattening, slitting, and rewinding to produce smaller coil units. During the slitting and coiling process, the sheet material is cut longitudinally to produce multiple strips, which are then rewound to form coil units. During the rewinding process, the coil units must be separated to prevent interference between the units.

[0033] like Figure 1-8 The figure shows a schematic diagram of an embodiment of the strip winding mechanism provided by the present invention.

[0034] Please refer to Figure 1-8 This embodiment is used for winding the strips of material obtained after slitting the material sheet. This embodiment includes a frame 110, which is equipped with a winding assembly 120 and a separator assembly 130.

[0035] In one embodiment, the winding assembly 120 includes a DC motor 122 and a first oil cylinder 123, which are mounted on the frame 110. A slit 124 is defined on the axial surface of the winding shaft 121, with the slit 124 being parallel to the axial direction of the winding shaft 121. The DC motor 122 is in transmission connection with the front end of the winding shaft 121 via a gear train 125, driving the winding shaft 121 to rotate. The first oil cylinder 123 is in transmission connection with the front end of the winding shaft 121, pushing the upper thrust plate 1213 and the lower thrust plate 1212 on the inner side of the winding shaft 121 to change the width of the slit 124.

The lower thrust plate 1212 is disposed on the outside of the main shaft 1211. Multiple lower thrust plates 1212 are evenly distributed around the circumference of the main shaft 1211. The lower thrust plate 1211 is elongated, with multiple continuous inclined steps on its outer surface. The upper thrust plate 1213 is disposed correspondingly to the lower thrust plate 1212. The opposing surfaces of the upper thrust plate 1213 and the lower thrust plate 1212 are provided with multiple inclined steps that match the inclined steps of the lower thrust plate 1212. The outer side of the upper thrust plate 1213 and the inner side of the circular plate 1214 form a gap 124. The arc plates 1214 are fixedly connected to the main shaft 1211 via a connecting shaft 1215. There are multiple arc plates 1214, each with a circular cross-section formed by its outer surfaces. There are gaps between adjacent arc plates 1214. The first oil cylinder 123 pushes the main shaft 1211, driving the lower thrust plate 1212 to push the upper thrust plate 1213 outward or pull the upper thrust plate 1213 inward, thereby changing the distance between the outer side of the upper thrust plate 1213 and the inner side of the arc plates 1214, thereby changing the width of the gap 124.

[0037] In one embodiment, the partition assembly 130 includes a bracket 132 connected to the frame 110. A partition shaft 131 is mounted on the bracket 132.

The pusher assembly 137 is used to unload the coil unit after winding, pushing the coil unit to move axially along the winding shaft 121 and separate from the winding shaft 121.

[0041] Specifically, the push plate 1371 is provided with an arc-shaped notch, the shape of which is larger than the radial cross-section of the reel 121 , so as to avoid interference between the push plate 1371 and the reel 121 when pushing the material.

[0042] In one embodiment, a shaft-lifting assembly 140 is further included.
