[0006] On the basis of the above technical scheme, preferably, two rollers are further arranged on the movable part and symmetrically arranged on both sides of the cutting blade; wherein when the wheel surface of the roller is attached to the outer circumferential wall of the steel coil, the cutting blade contacts the steel strip for cutting.

[0007] Further preferably, the radial surface of the roller and the radial surface of the cutting blade are cross arranged.

[0008] On the basis of the above technical scheme, preferably, a base is further arranged beside the steel coil; a rotating shaft is vertically arranged on the base; a rotating seat is arranged at one end of the rotating shaft and the other end of the rotating seat is arranged with the movable part; wherein the end of the rotating seat arranged with the movable part swings around the end of the rotating shaft; the movable part moves relative to the rotating seat along the extension direction of the two ends of the rotating seat, and the movable part approaches or moves away from the steel coil.

[0009] More preferably, it also includes a swing arm, one end of which is sleeved on the rotating shaft and the other end extends radially along the rotating shaft; and a telescopic mechanism, which is mounted on the base and whose output end is connected to the free end of the swing arm.

[0010] Based on the above technical solutions, preferably, it also includes two support seats, which are spaced apart on the outside of the two rollers and used to support the steel coil; wherein the two rollers are arranged between the two support seats.

[0011] More preferably, the upper surface of the support base is set as an inclined plane, with both inclined planes tilted toward the direction of the two rollers.

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] As Figure 1 shown, in combination with Figure 4The steel strip cutting device of the present application comprises two rollers 1, which are arranged at intervals and on which the steel roll 20 with the steel strip 21 is placed; a movable part 2, which is arranged beside the steel roll 20; and a cutting blade 3, which is arranged on the movable part 2 and is the main part of the cutting machine. In the present embodiment, the cutting machine is referred to as the cutting machine, which can be fixed on the movable part 2 by means of a clamp. The middle part of each roller 1 is provided with an annular groove 101, and when the steel roll 20 is placed on the two rollers 1, the steel strip 21 passes through the two grooves 101 at the same time. The movable part 2 with the cutting blade 3 moves relative to the steel roll 20, so that the cutting blade 3 approaches the steel strip 21 and cuts the steel strip 21. When the movable part 3 moves forward and approaches the surface of the steel roll 20, the cutting blade 3 is first released from the steel strip 21, and then the movable part 3 reciprocates along the axial direction of the steel roll 20, while the cutting blade 3 rotates in the cutting machine and cuts the steel strip. When the cutting blade 3 reciprocates synchronously with the movable part 3, the steel strip 21 can be gradually cut off. After the steel strip 21 is cut off, the two rollers 1 roll relative to each other. In this working condition, the steel roll 20 is subjected to two opposite frictional forces and does not roll, but the steel strip 21 wound on the surface of the steel roll 20 is cut off, and the two ends of the steel strip 21 are subjected to the frictional driving force of the two rollers 1, so that the steel strip 21 is extruded between the two rollers 1 and finally exits the groove 101. Thus, the steel strip 21 cut off can be removed without lifting the steel roll 20.

[0022] In Figure 2 In an optional embodiment shown in the figure, two rollers 4 are arranged on the movable part 2 and symmetrically arranged on both sides of the cutting blade 3. When the surface of the roller 4 is attached to the outer circumferential wall of the steel roll 20, the cutting blade 3 contacts the steel strip 21 for cutting. Side arms can be arranged on both sides of the clamp for clamping the cutting machine, and the roller 4 is installed on the side arm. The roller 4 has two functions: firstly, when the movable part 2 reciprocates, the surface of the roller 4 can be tightly attached to the surface of the steel roll 20, which helps to assist the reciprocating movement of the movable part 2; and secondly, the roller 4 extends to the steel roll 20 through the side arm, so that the roller 4 also plays a role in limiting the distance between the cutting blade 3 and the surface of the steel roll 20. The cutting edge of the cutting blade 3 is limited from contacting the surface of the steel roll 20 by tightly attaching the roller 4 to the surface of the steel roll 20. Since the steel strip 21 is tightly wound on the steel roll 20 and has a certain thickness, the cutting blade 3 will not damage the surface of the steel roll 20 when cutting the steel strip 21.

[0023] In Figure 2 In an optional embodiment shown in the figure, the radial surface of the roller 4 is arranged to intersect the radial surface of the cutting blade 3, so that the radial surface of the cutting blade 3 is not parallel to the radial surface of the steel strip 21. Therefore, the cutting blade 3 cuts the steel strip 21 obliquely, further avoiding damage to the surface of the steel roll 20 during cutting.

[0024] InFigure 3 In an optional embodiment shown, a base 5 is arranged beside the steel coil 20; a rotating shaft 6 is arranged vertically on the base 5; a rotating seat 7 is arranged on the rotating shaft 6, one end of which is sleeved on the top end of the rotating shaft 6 and the other end of which is provided with the movable part 2; wherein the end of the rotating seat 7 provided with the movable part 2 swings around the end of the rotating shaft 6; the movable part 2 moves along the extension direction of the two ends of the rotating seat 7 relative to the rotating seat 7, and approaches or moves away from the steel coil 20, and a telescopic rod can be arranged on the distal end of the rotating seat 7 to drive the movable part 2 to move forward and backward. When the above technical scheme is adopted, the movable part 2 is first driven by the telescopic rod to approach the steel coil 20, and the cutting blade 3 on the movable part 2 is then released from the steel strip 21, and then the position of the base 5 is fixed, while the distal end of the rotating seat 7 reciprocatingly rotates around the rotating shaft 6, thereby driving the movable part 2 and the cutting blade 3 thereon to reciprocatingly cut the steel strip 21; after the cutting is completed, the distal end of the rotating seat 7 stops swinging, and the movable part 2 is retracted to the initial position by the telescopic rod.

[0025] In Figure 3 In an optional embodiment shown, a swing arm 8 is arranged on the rotating shaft 6, one end of which is sleeved on the rotating shaft 6 and the other end of which extends radially along the rotating shaft 6; a telescopic mechanism 9 can be a telescopic electric rod, a telescopic air cylinder or the like, which is arranged on the base 5 and the output end of which is connected to the free end of the swing arm 8. When the above technical scheme is adopted, the output end of the telescopic mechanism 9 reciprocatingly extends and retracts to drive the swing arm 8 to reciprocatingly swing, thereby driving the distal end of the rotating seat 7 to reciprocatingly rotate.

[0026] In Figure 4 In an optional embodiment shown, two supporting seats 10 are arranged on the outer sides of the two rollers 1 and are used to support the steel coil 20; wherein the two rollers 1 are arranged between the two supporting seats 10. The supporting seat 10 is used to temporarily support the steel coil 20, and can be arranged as a right-angled trapezoid with the hypotenuse being two or three stepped.

[0027] In Figure 4 In an optional embodiment shown, the upper surface of the supporting seat 10 is arranged as a slope, both of which are inclined towards the direction of the two rollers 1, and the slope can support the steel coil 20 from the two sides of the bottom of the steel coil 20 to avoid the steel coil 20 from being separated from the supporting seat 10.

[0028] In Figure 4In an optional embodiment shown, a bottom plate 11 is arranged between the two supporting seats 10 and the two rollers 1 are arranged on the bottom plate 11; wherein the bottom plate 11 vertically moves up and down; when the bottom plate 11 is lifted to a first position, the bottom plate 11 lifts the two rollers 1 to support the steel coil 20 and make the steel coil 20 separate from the two supporting seats 10; when the bottom plate 11 is lowered to a second position, the bottom plate 11 lowers the two rollers 1 to place the steel coil 20 on the two supporting seats 10. The bottom plate 11 is provided with a jacking cylinder or the like at the bottom to drive the bottom plate 11 to move up and down; the bottom plate 11 is lifted to a higher position only when the rollers 1 need to rotate to provide a moving driving force for the steel coil 20 or the steel strip 21; generally, the bottom plate 11 is lowered to a lower position and does not contact the steel coil 20.

[0029] In Figure 4 In an optional embodiment shown, the groove 101 has a width greater than the width of the steel strip 21; when the forklift places the steel coil 20 on the two rollers 1, there is a larger redundant space to ensure that the steel strip 21 is located in the groove 101, so as to avoid that the steel strip 21 is pressed between the steel coil 20 and the rollers 1 and is difficult to move away.

[0030] As Figure 1 shown, in combination with Figure 2 , Figure 3 and Figure 4 , a use method of the steel coil and steel strip cutting device, the use method comprises the following steps: step one, placing the steel coil 20 on the two rollers 1 by the forklift and arranging the steel strip 21 in the groove 101; step two, driving the movable part 2 to approach the steel coil 20 relative to the rotating seat 7, and making the roller 4 adhere to the surface of the steel coil 20 and making the cutting blade 3 contact the steel strip 21; step three, starting the telescopic mechanism 9 to drive the rotating shaft 6 to reciprocatingly rotate axially through the swing arm 8, the rotating shaft 6 drives the rotating seat 7 to synchronously rotate, the rotating seat 7 drives the movable part 2 to reciprocatingly swing, in the swinging process of the movable part 2, the roller 4 rolls on the surface of the steel coil 20, and the cutting blade 3 reciprocatingly cuts the steel strip 21; step four, after the cutting blade 3 cuts off the steel strip 21, moving the movable part 2 to separate from the steel coil 20, and starting the two rollers 1 to drive the steel coil 20 to roll, the steel strip 21 rolls synchronously with the steel coil 20 and gradually exits the groove 101.

[0031] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
