Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a slitter with adjustable spacing includes a rotating cylinder 1. A plurality of longitudinal cutting blades 3 are assembled on the outer wall of the rotating cylinder 1. An inner clamping mechanism for clamping the inner circumference of the longitudinal cutting blades 3 is rotatably installed on the inner wall of the rotating cylinder 1. A limiting mechanism for limiting the inner clamping mechanism is provided at one end of the rotating cylinder 1; the inner clamping mechanism includes a rotating column 9 rotatably installed at the center of the inner wall of the rotating cylinder 1, and the rotating column 9 has an elliptical cylinder structure; the inner clamping mechanism includes two sliding grooves 4 opened inside the rotating cylinder 1. The two sliding grooves 4 are equidistantly distributed in a circumferential state. The sliding grooves 4 communicate with the inner cavity of the rotating cylinder 1, and the other end of the sliding grooves 4 penetrates to the outside of the rotating cylinder 1.

[0021] In this embodiment: when cutting the steel strip into several narrow strip steel strips, according to production needs, first adjust the spacing between the plurality of longitudinal cutting blades 3 until the adjustment is completed. Then, through the rotating part of the limiting mechanism, the inner clamping mechanism is driven to rotate, so that the inner clamping mechanism clamps and fixes the inner circumference of the plurality of longitudinal cutting blades 3, confines the longitudinal cutting blades 3 in the adjusted position, and fixes the plurality of longitudinal cutting blades 3.

[0022] Please pay special attention to Figure 1 、 Figure 2 And Figure 3 , a clamping plate 5 is slidably connected to the inner wall of the sliding groove 4. One end of the clamping plate 5 is formed with a vertical plate portion. One vertical plate portion is formed at the top of the clamping plate 5, and the other vertical plate portion is formed at the bottom of the other clamping plate 5. The end of the clamping plate 5 away from the vertical plate portion has a pressure receiving inclined surface 10. A plurality of connecting springs 11 are fixedly connected between the vertical plate portion and the inner wall of the rotating cylinder 1.

[0023] In this embodiment: when the rotating part of the limiting mechanism rotates, it drives the rotating column 9 to rotate. When the rotating column 9 rotates, it will gradually approach the pressure receiving inclined surface 10 until the rotating column 9 is squeezed against the pressure receiving inclined surface 10. At this time, the clamping plate 5 slides outward along the sliding groove 4 under the force, and the two clamping plates 5 sliding outward synchronously clamp the inner wall of the longitudinal cutting blade 3;

[0024] Similarly, when rotating in the reverse direction, the rotating column 9 rotates and resets and gradually separates from the pressure receiving inclined surface 10. At this time, the connecting spring 11 resets, which can drive the clamping plate 5 to reset and release the clamping of the longitudinal cutting blade 3.

[0025] Please refer specifically to Figure 1 and Figure 3 , at the position where the outer periphery of the rotating cylinder 1 is misaligned with the two sliding grooves 4, a limiting block 2 protruding outward is integrally formed, and the inner cavity of the longitudinal cutting blade 3 fits with the outer peripheries of the rotating cylinder 1 and the limiting block 2.

[0026] In this embodiment: The setting of the limiting block 2 can ensure that the longitudinal cutting blade 3 can rotate with the rotating cylinder 1. When performing longitudinal cutting operation, a driving motor is installed at one end of the rotating cylinder 1, and the driving motor can drive the longitudinal cutting blade 3 to rotate through the rotating cylinder 1 to achieve the longitudinal cutting function.

[0027] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 , the limiting mechanism includes rotating shafts integrally formed at both ends of the rotating column 9, the rotating shafts are rotatably connected to the rotating cylinder 1, one rotating shaft penetrates to the outside of the rotating cylinder 1, and a connecting head 6 is integrally formed at one end of the rotating shaft. An outwardly protruding protruding plate 7 is integrally formed on the outer periphery of the connecting head 6, and a limiting hole 8 is opened inside the protruding plate 7. The limiting mechanism further includes a sliding sleeve 12 integrally formed at an eccentric position at one end of the rotating cylinder 1. A return spring 16 is fixedly installed on the inner wall of the sliding sleeve 12. One end of the return spring 16 is connected to a limiting column 13. The limiting column 13 is slidably connected to the inner wall of the sliding sleeve 12, and one end of the limiting column 13 penetrates to the outside of the sliding sleeve 12. An outwardly protruding handle 14 is integrally formed at the outer peripheral end of the limiting column 13 located inside the sliding sleeve 12. The handle 14 has a "T" - shaped structure, and a strip - shaped groove 15 for the vertical rod part of the handle 14 to slide is opened inside the sliding sleeve 12.

[0028] In this embodiment: When clamping the longitudinal cutting blade 3, by applying an external force to cause the connecting head 6 to rotate, the connecting head 6 drives the rotating column 9 to rotate self - rotatably through the rotating shaft. At the same time, the connecting head 6 drives the protruding plate 7 to rotate. At the same time, by applying a thrust to the handle 14, the handle 14 slides along the strip - shaped groove 15, and the handle 14 drives the limiting column 13 to slide along the inner wall of the sliding sleeve 12 until one side of the protruding plate 7 contacts the side surface of the limiting plate 17. At this time, the connecting head 6 and the protruding plate 7 cannot continue to rotate, and the limiting hole 8 and the limiting column 13 are in an aligned state. At this time, the force applied to the handle 14 is removed, and at this time, the return spring 16 resets, driving the limiting column 13 to snap into the inner wall of the limiting hole 8 to complete the limiting of the rotating column 9.

[0029] Please refer specifically to Figure 3 , the inner diameter of the limiting hole 8 is equal to the outer diameter of the limiting column 13, and a limiting plate 17 protruding outward is integrally formed at one end of the limiting block 2.

[0030] In this embodiment, by providing the limiting plate 17, the rotational limit of the connector 6 can be achieved, avoiding the problem that the limiting hole 8 and the limiting post 13 are not easily aligned during rotation.

[0031] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
