Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, and more specifically, to a slitting circular blade for longitudinal slitting. Background Art

[0002] A slitting machine, also known as a slitting line or a slitting cutter, is used to uncoil, longitudinally slit, and rewind a metal coil into a strip coil of the required width, and is suitable for processing various metal materials such as cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, and those with surface coating.

[0003] For example, a patent document with the publication number CN219053066U discloses an improved slitting circular blade. Through the provided first U-shaped frame, first circular blade, drive shaft seat, side frame, second U-shaped frame, second circular blade, through slot, limit piece slot, and wear-resistant pad, the utility model can achieve efficient, stable, and continuous slitting operation on metal coil sheets. During actual use, the staff can pass the metal coil sheet to be slit through the space between the first U-shaped frame and the second U-shaped frame, and then use the first circular blade and the second circular blade on the inner side walls of the first U-shaped frame and the second U-shaped frame respectively to perform stable slitting and cutting operations on both sides of the metal coil sheet.

[0004] However, when the above structure is used for slitting metal coil plates, it cannot adjust the above structure according to the size of the metal coil plate, so that the above structure cannot slit metal coil plates of different sizes, and is only limited to slitting metal coil plates of specified sizes, which greatly affects its practicality.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0006] In view of the problems in the related technology, the utility model provides a slitting circular blade for longitudinal slitting to overcome the above technical problems existing in the existing related technology.

[0007] Therefore, the specific technical solution adopted by the utility model is as follows:

[0008] A slitting circular blade, comprising a bottom box, on which U-shaped frames are symmetrically arranged. The U-shaped frames are slidably connected to the bottom box. A sliding assembly is provided on the bottom box. The inner side walls of the U-shaped frames are provided with circular blade bodies. A driving shaft seat is arranged inside the circular blade bodies. A regulating support is fixedly connected to the side of the driving shaft seat. A regulating assembly is arranged inside the regulating support. The regulating assembly includes a regulating cavity opened inside the regulating support. A lead screw is rotatably connected inside the regulating cavity. Symmetrical sliding circular blocks are arranged on the lead screw. The sliding circular blocks are in threaded connection with the lead screw. First connecting pieces are welded at equal intervals on the outer surfaces of the sliding circular blocks. Side grooves are opened at equal intervals on the outer surface of the regulating support. The side grooves communicate with the regulating cavity. A regulating slider is slidably connected inside the side grooves. A second connecting piece is fixedly connected to the inner side of the regulating slider. The second connecting piece is connected to the first connecting piece through a connecting rod.

[0009] Further, to facilitate the sliding of the U-shaped frames, the sliding assembly includes a bottom cavity opened inside the bottom box. A bidirectional threaded rod is rotatably connected inside the bottom cavity. Symmetrical T-shaped sliders are arranged on the bidirectional threaded rod. The T-shaped sliders are in threaded connection with the bidirectional threaded rod. The tops of the T-shaped sliders all extend outside the bottom box and are fixedly connected to the U-shaped frames.

[0010] Further, to enable the regulating sliders to slide stably inside the side grooves, sliding grooves are opened at both ends of the inner surface of the side grooves. Sliding blocks are fixedly connected to both ends of the outer surface of the regulating slider. The sliding blocks are slidably connected to the sliding grooves.

[0011] Further, to facilitate the separation of metal coil sheets, an adjusting screw is threadedly connected to the outer side wall of the U-shaped frame. A through hole is opened at one end of the U-shaped frame close to the adjusting screw. One end of the adjusting screw extends into the through hole and is connected to a limiting vertical block. The limiting vertical block is slidably connected to the through hole. An arc-shaped block is fixedly connected to the inner side of the limiting vertical block.

[0012] Further, to enable the limiting vertical block to slide stably inside the through hole, limiting grooves are opened at the top and bottom ends of the inner surface of the through hole. Limiting blocks are fixedly connected to the top and bottom ends of the outer surface of the limiting vertical block. The limiting blocks are slidably connected to the limiting grooves.

[0013] Further, to facilitate the rotation of the lead screw, an adjusting groove is opened at one end of the U-shaped frame far from the through hole. One end of the lead screw extends into the adjusting groove and is fixedly connected to an adjusting turntable.

[0014] Further, to increase the friction between the regulating slider and the metal coil sheet, an anti-slip gasket is fixedly connected to the outer side of the regulating slider.

[0015] Furthermore, in order to facilitate the rotation of the bidirectional threaded rod, one end of the bidirectional threaded rod extends outside the bottom box and is connected to a crank.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The staff places the metal coil plate to be slit between the U-shaped frames. By rotating the crank, the bidirectional threaded rod rotates in the bottom cavity, and the two T-shaped sliders slide towards each other. The sliding of the T-shaped sliders towards each other positions the adjusting support at the central part of the metal coil plate, facilitating the fixation of the metal coil plate. The sliding of the T-shaped sliders towards each other is convenient for fixing metal coil plates of different lengths.

[0018] 2. When the adjusting support is at the central part of the metal coil plate, rotate the adjusting turntable, so that the lead screw rotates in the adjusting cavity, and the two sliding circular blocks slide towards each other. The sliding of the sliding circular blocks causes the connecting rod to move, and the adjusting slider slides in the side groove. The sliding of the adjusting slider makes the surface with the anti-slip gasket contact the inner surface of the central part of the metal coil plate, fixing the metal coil plate on the adjusting support. The sliding of the adjusting slider can fix metal coil plates of different sizes. The two sides of the metal coil plate are slit and cut by the disc blade body on the inner side wall of the U-shaped frame. The metal strips cut out from both sides of the metal coil plate can pass through the through holes, facilitating the separation operation of the metal coil plate. Description of the Drawings

The staff places the metal coil plate to be slit between the U-shaped frames 6. By rotating the crank 5, the bidirectional threaded rod 3 rotates in the bottom cavity 2, and the two T-shaped sliders 4 slide towards each other. The sliding of the T-shaped sliders 4 towards each other facilitates the fixation of metal coil plates of different lengths.

[0029] Embodiment 2;

[0030] Please refer to Figures 1-3, a disk blade body 7 is provided on the inner sidewall of the U-shaped frame 6. A drive shaft seat 8 is provided inside the disk blade body 7. An adjusting support 9 is fixedly connected to the side of the drive shaft seat 8. An adjusting component is provided inside the adjusting support 9. The adjusting component includes an adjusting cavity 10 opened inside the adjusting support 9. A lead screw 11 is rotatably connected inside the adjusting cavity 10. Symmetrically arranged sliding round blocks 12 are provided on the lead screw 11. The sliding round blocks 12 are threadedly connected to the lead screw 11. First connecting pieces 13 are welded equidistantly on the outer surface of the sliding round blocks 12. Side grooves 14 are opened equidistantly on the outer surface of the adjusting support 9. The side grooves 14 communicate with the adjusting cavity 10. An adjusting slider 15 is slidably connected inside the side grooves 14. In order to enable the adjusting slider 15 to slide stably inside the side grooves 14, sliding grooves 17 are opened at both ends of the inner surface of the side grooves 14. Sliding blocks 16 are fixedly connected to both ends of the outer surface of the adjusting slider 15. The sliding blocks 16 are slidably connected to the sliding grooves 17. A second connecting piece 19 is fixedly connected to the inner side of the adjusting slider 15. The second connecting piece 19 is connected to the first connecting piece 13 through a connecting rod 20. An anti-slip gasket 18 is fixedly connected to the outer side of the adjusting slider 15. In order to facilitate the separation of the metal coil plate, an adjusting screw 24 is threadedly connected to the outer sidewall of the U-shaped frame 6. A through hole 23 is opened at one end of the U-shaped frame 6 close to the adjusting screw 24. One end of the adjusting screw 24 extends into the through hole 23 and is connected to a limiting vertical block 25. The limiting vertical block 25 is slidably connected to the through hole 23.

An adjusting groove 21 is opened at one end of the U-shaped frame 6 far from the through hole 23. One end of the lead screw 11 extends into the adjusting groove 21 and is fixedly connected to an adjusting turntable 22. When the adjusting support 9 is at the central part of the metal coil plate, rotate the adjusting turntable 22 to make the lead screw 11 rotate inside the adjusting cavity 10 and make the two sliding round blocks 12 slide towards each other. The sliding of the sliding round blocks 12 causes the connecting rod 20 to move and makes the adjusting slider 15 slide inside the side grooves 14. The sliding of the adjusting slider 15 makes the side with the anti-slip gasket 18 contact the inner surface of the central part of the metal coil plate, fixing the metal coil plate on the adjusting support 9. The sliding of the adjusting slider 15 can fix metal coil plates of different sizes. The disk blade body 7 on the inner sidewall of the U-shaped frame 6 performs slitting operations on both sides of the metal coil plate. The metal strips cut out from both sides of the metal coil plate can pass through the through hole 23, facilitating the separation operation of the metal coil plate.

[0031] For the convenience of understanding the above technical solution of the present utility model, the working principle or operation method of the present utility model in the actual process will be described in detail below.

[0032] In actual application, first, the staff places the metal coil plate to be slit between the U-shaped frames 6. Secondly, the crank 5 is rotated to make the bidirectional threaded rod 3 rotate in the bottom cavity 2, and the two T-shaped sliders 4 slide towards each other.

Then, the adjusting turntable 22 is rotated to make the lead screw 11 rotate in the adjusting cavity 10, and the two sliding round blocks 12 slide towards each other. The sliding of the sliding round blocks 12 causes the connecting rod 20 to move, and the adjusting slider 15 slides in the side groove 14. The sliding of the adjusting slider 15 makes the surface with the anti-slip gasket 18 contact the inner surface of the central part of the metal coil plate, fixing the metal coil plate on the adjusting support 9. The two sides of the metal coil plate are slit and cut by the disc blade body 7 on the inner side wall of the U-shaped frame 6. The metal strips cut out from the two sides of the metal coil plate can pass through the through holes 23, facilitating the separation operation of the metal coil plate.
