DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The cold rolled steel coil can be pressed down when it is cut to prevent it from shifting or warping. Figure 1-4 As shown, a cold-rolled steel coil slitting machine described in the utility model comprises a base 1, a slitting assembly 3 and a pressing assembly 5, a structural seat 4 is fixed to the top of the base 1 by bolts, a pressing assembly 5 is arranged on the top of the structural seat 4, the pressing assembly 5 comprises a second gantry 501 fixed to the top of the structural seat 4 by bolts, vertical rods 502 are sleeved through both ends of the top of the second gantry 501, the bottom end of the vertical rod 502 located inside the second gantry 501 is connected to the second structural frame 503 through a threaded groove, a pressing roller 504 is rotatably connected to the inside of the second structural frame 503 through a bearing, and a compression spring 505 is sleeved on the outer side of the vertical rod 502 located inside the second gantry 501;

[0024] The top of the base 1 located outside the structural seat 4 is fixed with a first gantry 2 by bolts, and a cutting assembly 3 is arranged on the top of the first gantry 2. The cutting assembly 3 includes an internal threaded sleeve 301 welded to the top of the first gantry 2, and a screw rod 302 is inserted through the internal threaded sleeve 301.

[0025] When in use, the compression spring 505 pushes the second structural frame 503 downward, so that the pressing roller 504 at the bottom of the second structural frame 503 presses on the cold-rolled steel coil, which can press the cold-rolled steel coil without affecting its movement, thereby preventing the cold-rolled steel coil from warping and shifting.

[0026] In order to slit the cold rolled steel coil, for example, Figure 2 As shown, the utility model also includes that the bottom end of the screw rod 302 located inside the first gantry 2 is connected to the first structural frame 303 through a bearing, the first structural frame 303 is rotatably connected to a slitting roller 304 through a bearing, and one end of the first structural frame 303 is installed with a driving motor 305 through a mounting frame.

[0027] When in use, the driving motor 305 drives the slitting roller 304 to rotate, so as to slit the cold-rolled steel coil.

[0028] For example, Figure 2 As shown, the utility model also includes that the two ends of the top of the first structural frame 303 are connected with auxiliary rods 306 through threaded grooves, the auxiliary rods 306 pass through the first gantry 2, and the top of the screw rod 302 is provided with a rocker 307 through a flat key fixing sleeve.

[0029] When in use, the screw rod 302 can be rotated by holding the rocking plate 307 , and the auxiliary rod 306 can improve the structural stability of the first structural frame 303 without affecting its up and down movement.

[0030] For example, Figure 2 As shown, the utility model also includes that the output shaft on one side of the driving motor 305 is fixedly connected to one end of the slitting roller 304 through a connecting sleeve.

[0031] When in use, the driving motor 305 can drive the slitting roller 304 to rotate.

[0032] For example, Figure 1 , Figure 4 As shown, the utility model also includes that auxiliary rollers 6 are installed at both ends of the top of the base 1 through mounting frames, and knife grooves 7 corresponding to the slitting rollers 304 are equidistantly opened on the top of the structural seat 4.

[0033] When in use, the knife groove 7 can prevent the slitting roller 304 from cutting the top of the structural seat 4, and the auxiliary roller 6 can facilitate the movement of the cold-rolled steel coil on the base 1 and the structural seat 4.

[0034] When the utility model is used, the device is connected to an external power source using a power cord, and one end of the cold-rolled steel coil is passed through the second gantry 501 and the first gantry 2 in sequence, and fixed on an external winding device;

[0035] The external winding device drives the cold-rolled steel coil to move. The shaking plate 307 is held to rotate the screw rod 302. The screw rod 302 rotates and pushes the first structural frame 303 downward through the internal thread sleeve 301, so that the slitting roller 304 presses the cold-rolled steel coil onto the structural seat 4. The driving motor 305 is turned on to drive the slitting roller 304 to rotate, so that the cold-rolled steel coil can be slit.

[0036] When one end of the cold-rolled steel coil passes through the second gantry 501, the compression spring 505 on the outside of the vertical rod 502 pushes the second structural frame 503 downward, so that the pressing roller 504 at the bottom of the second structural frame 503 presses on the cold-rolled steel coil, which can press the cold-rolled steel coil without affecting its movement, thereby preventing the cold-rolled steel coil from being tilted or shifted when the slitting roller 304 slits the cold-rolled steel coil.

[0037] The opening of multiple knife grooves 7 can prevent the rotating slitting roller 304 from contacting the structural seat 4. The auxiliary rod 306 can improve its structural stability without affecting the up and down movement of the first structural frame 303. The setting of the auxiliary roller 6 facilitates the movement of the cold-rolled steel coil on the base 1 and the structural seat 4.
