[0042] Working principle:

[0043] First, when in use, the distance between the shearing cutter disc 1205 on the surface of the rotating shaft 1202 on the longitudinal shearing assembly 12 is adjusted according to the shearing requirements of the cold-rolled coil. After the adjustment, the adjusting screw 1207 at the upper end of the limiting frame 1206 on the side of the shearing cutter disc 1205 is rotated so that the adjusting screw 1207 and the clamping plate 1208 inside the limiting frame 1206 can be threadedly moved, so that the clamping plate 1208 slides downward inside the limiting frame 1206 so that the clamping plate 1208 is clamped into the limiting block 1204 inside the groove 1203 on the surface of the rotating shaft 1202, which is convenient for the positioning of the shearing cutter disc 1205 after adjustment. Then, the driving motor 1201 is used so that the driving motor 1201 drives the rotating shaft 1202 to rotate, so that the shearing cutter disc 1205 can perform longitudinal shearing on the cold-rolled coil.

[0044] When the cold-rolled coil is wound, the first motor 1301 and the second motor 1307 on the grinding assembly 13 can be turned on so that the first motor 1301 drives the first grinding wheel 1303 to rotate through the first connecting rod 1302, and the second motor 1307 drives the second grinding wheel 1306 to rotate through the second connecting rod 1305. The upper end surface of the first grinding wheel 1303 is flush with the upper end surface of the fixed drive roller 3, so that the lower end surface of the cold-rolled coil can be ground after shearing.

[0045] The lower end surface of the second grinding wheel 1306 can drive the second motor 1307 to move downward through the electric telescopic rod 1308, so that the second connecting rod 1305 slides on the second slot 1304, so that the lower end surface of the second grinding wheel 1306 fits with the upper end surface of the cold-rolled coil, so as to grind the incision on the upper end surface of the cold-rolled coil.

[0046] The utility model discloses a longitudinal shearing mechanism for cold-rolled coils, which can adjust the distance between different shearing discs by using a shearing disc that can slide on the surface of a rotating shaft on a longitudinal shearing assembly, and at the same time cooperate with the threaded movement of the adjusting screw rod and the clamping plate inside the limiting frame, so that the clamping plate is clamped between the limiting blocks inside the groove on the surface of the rotating shaft, so as to facilitate the positioning of the shearing disc after adjustment, and facilitate the shearing assembly to be used for shearing cold-rolled coils of different widths;

[0047] The longitudinal shearing mechanism of the cold-rolled coil of the utility model can use the grinding component located on the side of the shearing component on the machine base so as to grind the surface of the sheared cold-rolled coil by the first grinding wheel and the second grinding wheel to avoid the phenomenon of uneven cuts after the cold-rolled coil is sheared.
