[0028] Coil 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 reeling line, the coil undergoes steps such as unwinding, leveling, slitting, and rewinding to produce smaller coils. During the slitting process, the sheet material is cut longitudinally into multiple strips. These strips tend to overlap in the buffer pit, so they must be pre-separated before being coiled to facilitate subsequent reeling.

[0029] like Figure 1-4 The figure shows an embodiment of the material strip pre-separation mechanism provided by the present invention.

[0030] Please refer to Figure 1-4 This embodiment is used for pre-splitting web strips before winding. It includes a frame 110 equipped with a tensioning assembly 120 and at least two separator rollers 130. Multiple separator rollers 130 are arranged in parallel. A pressure roller 140 is positioned between adjacent separator rollers 130. The tensioning assembly 120 is positioned adjacent to the separator rollers 130, which are located at the entrance of the tensioning assembly 140. Separator rollers 130 are provided with multiple partitions 131 on their surfaces. These partitions 131 are used to separate the web strips after slitting. The tensioning assembly 120 applies tension to the separated web strips.

[0031] The partitions 131 in each separator roller 130 have the same spacing width, and the spacing between each separator roller 130 is aligned with each other. Bushings 132 are provided between the partitions 131 in the separator rollers 130, which secure and separate the partitions 131. The sheet strips are located between adjacent partitions 131. This embodiment uses two separator rollers 130, which extend the separation interval of the separator rollers 130, ensuring the separation effect of the sheet strips and effectively reducing the risk of overlap after the sheet strips are separated by a single separator roller 130. The tension assembly 120 applies pressure to the separated sheet strips to reduce the lateral displacement of the sheet strips, which could cause overlap.

[0032] In one embodiment, the tension assembly 120 includes an upper pressure block 121, a lower pressure block 122, and a first oil cylinder 123. The upper pressure block 121, lower pressure block 122, and first oil cylinder 123 are mounted on the frame 110. The upper pressure block 121 is positioned above the lower pressure block 122, which is fixedly connected to the frame 110. The upper pressure block 121 and lower pressure block 122 are positioned opposite each other, and the space between the upper pressure block 121 and lower pressure block 122 is used to pass the web into strips. The telescopic end of the first oil cylinder 123 is connected to the upper pressure block 121, and the first oil cylinder 123 drives the upper pressure block 121 toward or away from the lower pressure block 122.

[0033] Furthermore, there are two first oil cylinders 123, the telescopic ends of which are connected to the upper pressing block 121 via a second synchronizing shaft 124. A second gear 125 is provided at each end of the second synchronizing shaft 124, and the frame 110 is provided with a second rack 126, which meshes with the second gear 125. The second synchronizing shaft 124 ensures that the upper pressing block 121 moves synchronously as a whole, making the tension applied by the upper pressing block 121 to the sheet strip more uniform.

[0034] In one embodiment, the pressing surfaces of the upper pressing block 121 and the lower pressing block 122 are respectively provided with felt 127. When the sheet strips pass through the upper pressing block 121 and the lower pressing block 122, the felt 127 can remove debris on the surface of the sheet strips.

[0035] In one embodiment, the separator rollers 130 include a first separator roller 133 and a second separator roller 134. The first separator roller 133 is mounted on a lifting platform 135. A second oil cylinder 136 is provided on the frame 110. The telescopic end of the second oil cylinder 136 is connected to the lifting platform 135. The second oil cylinder 136 drives the lifting platform 135 up and down. Changing the height of the lifting platform 135 changes the height of the first separator roller 133, thereby varying the height difference between the first separator roller 133 and the second separator roller 134. The second separator roller 134 is mounted on the frame 110 at a fixed height. A pressure roller 140 is provided between the first and second separator rollers 133, 134.

[0036] In one embodiment, the lifting platform 135 is connected to the guide rod 1351, the guide rod 1351 is provided on the frame 110, and the guide rods 1351 are respectively provided on both sides of the lifting platform 135. Adjacent guide rods 1351 are connected by a first synchronization shaft 1352. The guide rod 1351 is provided with a vertical first rack 1353, and first gears 1354 are provided at both ends of the synchronization shaft 1352. The first gear 1354 is engaged with the first rack 1353.

[0037] In one embodiment, the lifting platform 135 is provided with an auxiliary roller 1355 . The auxiliary roller 1355 is arranged parallel to the first separating roller 133 . The height of the auxiliary roller 1355 is lower than that of the first separating roller 133 .

[0038] Specifically, the web strip passes through the auxiliary roller 1355, the first separator roller 133, and the pressure roller 140 in sequence, then passes between the pressure roller 140 and the second separator roller 134 to the top of the second separator roller 234, and finally passes through the tension assembly 120. The height of the auxiliary roller 1355 is lower than that of the first separator roller 133, and the first separator roller 133 is lower than that of the second separator roller 134. This height difference can apply downward pressure to the web strip passing through, thereby tensioning the web strip.

[0039] In one embodiment, one end of the separator roller 130 is connected to the frame 110 via a support base 137. A movable slide 138 is provided below the support base 137. The movable slide 138 is connected to the frame 110, and the support base 137 can slide along the movable slide 138 to separate from the separator roller 130. The support base 137 is used to support the separator roller 130. After the support base 137 is separated from the separator roller 130 via the movable slide 138, the separators 131 and sleeves 132 mounted on the separator roller 130 can be replaced and adjusted, and the width between the separators 131 can be adjusted to accommodate the width of the strips of the web.

[0040] In one embodiment, third cylinders 141 are provided at both ends of the pressing roller 140. The third cylinders 141 are installed on the frame 110. The third cylinders 141 drive the pressing roller 140 to rise and fall. A supporting plate 142 is provided below the pressing roller 140. The supporting plate 142 rises and falls synchronously with the pressing roller 140. The supporting plate 142 is used to support the slits of the web.

[0041] like Figure 5 The figure shows a schematic diagram of an embodiment of the volume separation system provided by the present invention.

[0042] Please refer to Figure 5 This embodiment is used for winding coiled materials into strips. This embodiment includes an unwinding mechanism 500, a slitting mechanism 400, a material strip pre-separating mechanism 100, and a winding mechanism 600, which are arranged in sequence. A flattening mechanism 200 and a material cutting mechanism 300 are arranged between the unwinding mechanism 500 and the slitting mechanism 400, and a flattening mechanism 200 and a material cutting mechanism 300 are arranged between the material strip pre-separating mechanism 100 and the winding mechanism 600. That is, the unwinding mechanism 500, the flattening mechanism 200, the material cutting mechanism 300, the slitting mechanism 400, the material strip pre-separating mechanism 100, the flattening mechanism 200, the material cutting mechanism 300, and the winding mechanism 600 are arranged in sequence.

[0043] The unwinding mechanism 500 is used to load the coiled material and unwind the coiled material into sheets and convey it to the flattening mechanism. The first flattening mechanism 200 receives the unwinded sheet and flattens it and conveys it to the first shearing mechanism 300. The shearing mechanism 300 is used to shear the sheet horizontally. In this embodiment, it is mainly used to shear the material head. The sheet with the sheared material head is conveyed to the longitudinal shearing mechanism 400. The longitudinal shearing mechanism 400 longitudinally shears the sheet to obtain strips. The sheet strip pre-separation mechanism 100 separates the strips in parallel. The separated strips are conveyed to the second flattening mechanism 200 for flattening and the second shearing mechanism 300 for shearing the material head. Finally, they are conveyed to the winding mechanism 600 for winding to obtain multiple coil units. It also includes a film laminating mechanism 700, which is arranged between the flattening mechanism 200 and the shearing mechanism 300, specifically the flattening mechanism 200 and the shearing mechanism 300 between the unwinding mechanism 500 and the longitudinal shearing mechanism 400. The film laminating mechanism 700 is used to laminar the upper and lower surfaces of the web.

[0044] The slitting mechanism 400 and the web stripping and pre-separating mechanism 100 are connected by a conveyor belt 900. The waste recovery mechanism 800 is located on both sides of the conveyor belt 900 between the slitting mechanism 400 and the web stripping and pre-separating mechanism 100. The waste recovery mechanism 800 is used to recover waste material from both sides of the web after the slitting mechanism 400 slits the web.
