[0047] Coil refers to the plate material that is rolled into a roll for the convenience of transportation and storage, which can be steel coil, aluminum coil, etc. In the slitting production line, the coil is unrolled, leveled, slitting, and rewinding to obtain a coil unit with a smaller width. In the slitting process, the sheet is slitting to obtain multiple strips, and finally the strips need to be rewinded to obtain a coil unit.

[0048] like Figure 1-24 The figure is a schematic diagram of an embodiment of the roll material splitting system provided by the present invention.

[0049] Please refer to Figure 1-24 This embodiment is used for winding the coiled material in strips, and includes an unwinding mechanism 100, a longitudinal cutting mechanism 400, a pre-separating mechanism 500, and a winding mechanism 600 which are arranged in sequence. A flattening mechanism 200 and a shearing mechanism 300 are arranged between the unwinding mechanism 100 and the longitudinal cutting mechanism 400, and a flattening mechanism 200 and a shearing mechanism 300 are arranged between the pre-separating mechanism 500 and the winding mechanism 600. That is, the unwinding mechanism 100, the flattening mechanism 200, the shearing mechanism 300, the longitudinal cutting mechanism 400, the pre-separating mechanism 500, the flattening mechanism 200, the shearing mechanism 300, and the winding mechanism 600 are arranged in sequence.

[0050] The unwinding mechanism 100 is used to load the coil and unwind the coil into a sheet and convey it to the flattening mechanism. The first flattening mechanism 200 receives the unwinding sheet and flattens it and conveys it to the first cutting mechanism 300. The cutting mechanism 300 is used to shear the sheet horizontally. In this embodiment, it is mainly used to shear the head of the sheet. The sheet with the head of the sheet cut is conveyed to the longitudinal cutting mechanism 400. The longitudinal cutting mechanism 400 longitudinally cuts the sheet to obtain strips. The pre-separation mechanism 500 separates the strips in parallel. The separated strips are conveyed to the second flattening mechanism 200 for flattening and the second cutting mechanism 300 for shearing the head of the sheet. Finally, they are conveyed to the winding mechanism 600 for winding to obtain multiple coil units.

The expansion and contraction shaft 121 expands and contracts the inner wall of the coil hole. Compared with the connecting rod transmission mode, this transmission mode structure can withstand greater external force. The pressure arm assembly 130 is arranged above the expansion and contraction reel assembly 120, and can be close to or away from the coil, and exert pressure on the axial surface of the coil to prevent the coil from spreading. The shaft lifting arm assembly 140 moves upward from bottom to the front end of the expansion and contraction shaft 121 to support the front end of the expansion and contraction shaft 121 .

The telescopic assembly 830 is in transmission connection with the coil assembly 840, and the telescopic assembly 830 drives the coil assembly 840 to expand or contract. When the coil assembly 840 expands, the waste material is rolled up, and when the coil assembly 840 contracts, the rolled waste material is separated from the coil assembly 840, and the unloading is completed. The material guide assembly 850 is arranged on the side of the coil assembly 840.

The connecting strips 844 can be in a vertical state, and the cylindrical structure formed by the plurality of connecting strips 844 serves as the main axis for winding the waste material. The head end of the connecting strip 844 is connected to the rotating plate 841, and the tail end of each connecting strip 844 is respectively connected to a support strip 843, and the tail end of the connecting strip is connected to the middle of the support strip 843.

Specifically, the supporting surface formed by the support strips 843 is circular, and the cross-sectional size formed by the connecting strips 844 is circular. Because the circular shape of the supporting surface is larger than the cross-sectional size, the size of the supporting surface can match the size of the rotating plate 841. The supporting surface formed by the support strips 843 is used to support the waste material wound by the connecting strips 844.

[0092] When the telescopic assembly 830 drives the rotating shaft 842 to move downward in the axial direction, the support bars 843 are stretched outward. When the rotating shaft 842 moves downward to the end of the interval, the connecting bars 844 are in a vertical state, and the supporting surface surrounded by the supporting bars 843 is opposite to the rotating plate 841. The outer diameter of the supporting surface surrounded by the supporting bars 843 is larger than the cross-sectional size surrounded by the connecting bars 844. The support bars 843 are used for waste winding in the stretched state.

[0093] When the telescopic assembly 830 drives the rotating shaft 842 to move upward in the axial direction, the support bar 843 shrinks inward, and the lower side of the connecting bar 844 shrinks inward.

The waste strip passes through the guide port 852 and is wound in the coil assembly 840. The lifting cylinder 851 drives the guide port 852 to move up and down, and then drives the waste strip passing through the guide port 852 to move up and down, so that the waste is wound evenly.

[0097] Furthermore, the guide port 852 includes a support frame 8521 and a plurality of rollers 8522. The support frame 8521 is connected to the telescopic end of the lifting cylinder 851. The rollers 8522 are arranged on the support frame 8521. The plurality of rollers 8522 form a through hole 8523 for the waste strip to pass through. Specifically, the number of rollers 8522 is 4, and the four rollers 8522 form a rectangular through hole 8523.
