[0002] The bottom knife sleeve of the slitting machine is a device used to install and adjust the blade of the slitting machine. It ensures the correct positioning and stable cutting of the blade. The bottom knife sleeve of the slitting machine is a key mechanical component and plays a vital role in the slitting process. Correct selection, installation and maintenance of the bottom knife sleeve are of great significance to improving the quality and efficiency of slitting. The bottom knife sleeve needs to be clamped with a fixture during production and processing to facilitate processing. Most of the existing fixtures use movable blocks that can move in a straight line to clamp the bottom knife sleeve. The contact surface of the fixture with the bottom knife sleeve is small when in use, and it is easy to slip during the clamping process. It does not have the function of automatically adjusting and adapting according to the curvature of the outer surface of the bottom knife sleeve, and the clamping effect is not good when used.

The inner side of the rotating block 6 passes through and is movably connected to a fixed column 7, and the bottom end of the fixed column 7 is fixedly connected to the base 5. The top of the rotating block 6 is fixedly connected to a claw 8, and the claw 8 is arc-shaped. The outer surfaces of both ends of the claw 8 are fixedly connected to gaskets 9, which are made of rubber material and can play an anti-slip role. The inner side of the main body 1 is rotatably connected to a first screw 10, which is a double-thread screw Rod, the threads at both ends of the first screw rod 10 are symmetrically distributed, and the two ends of the first screw rod 10 are threadedly connected to the two first screw rods 10 respectively. One end of the first screw rod 10 passes through the main body 1 and is fixedly connected to the first knob 11. A placement table 12 is provided in the middle of the upper surface of the main body 1, and a bottom knife sleeve 20 is placed on the upper end of the placement table 12. The inner sides of the two movable beams 3 are rotatably connected to the first bevel gear 13, and the bottom ends of the two movable beams 3 are fixedly connected to the movable column 14. The inner lower end of the movable column 14 is rotatably connected to the second bevel gear 15. The movable beam 3 and the inner side of the movable column 14 are rotatably connected to the bevel gear rod 16. The upper and lower ends of the bevel gear rod 16 are respectively meshed with the first bevel gear 13 and the second bevel gear 15. The inner lower end of the main body 1 is rotatably connected to the rotating rod 17. The cross section of the rotating rod 17 is a regular hexagon, which is not only convenient for processing, but also can avoid idling during transmission. The rotating rod 17 passes through and is transmission-connected to the two second bevel gears 15 at the same time. One end of the rotating rod 17 passes through the main body 1 and is fixedly connected to the second knob 18. The inner side of the first bevel gear 13 passes through and is fixedly connected to the second screw 19. The second screw 19 is a double-threaded screw. The threads at both ends of the second screw 19 are symmetrically distributed. The two ends of the second screw 19 are respectively threadedly adapted to the two threaded blocks 4. The first screw 10 can be driven to rotate by the first knob 11, so that the two movable beams 3 can be moved closer to or away from each other. The claw 8 can be driven to rotate by the rotating block 6, so that the bottom knife sleeve 20 can be achieved by the rotation of the claw 8. The arc-shaped outer surface is used for stable clamping, and the gasket 9 can prevent slipping.

Therefore, the movable column 14 is not affected when the movable beam 3 drives the movable column 14 to move. The second bevel gear 15 is connected to the first bevel gear 13 through the bevel gear rod 16, which in turn drives the second screw 19 to rotate. The second screw 19 can be used to move the two threaded blocks 4 closer or farther away. The threaded block 4 can drive the base 5 and the rotating block 6 inside it to move, so that when the bottom knife sleeve 20 is too large or too small, it can be clamped after adjustment, which improves the effect during use.
