Technical Field
[0001] The utility model relates to a clutch connecting rod mechanism with a function of detecting the lifting height of a knife shaft, belonging to the technical field of slitting machine equipment. Background Art
[0002] Slitting machines are essential equipment for steel production, used for longitudinal shearing of metal strips. A typical slitting machine structure consists of a power-driven cutter shaft seat and a movable cutter shaft seat. The cutter shaft seat houses a slider, which is attached to a screw lift. The slider and screw lift are fixedly connected, housing the cutter shaft. The screw lifts are connected by a connecting rod, allowing the cutter shafts to rise and fall synchronously. If the two ends of the cutter shaft rise and fall inconsistently, the sheared material quality can be low, and in severe cases, damage can occur to the blades or even cause the cutter shaft to shut down, impacting production schedules. When the cutter shaft seat is assembled and the movable cutter shaft seat is removed, the connecting rod between the screw lifts will not disengage.
[0003] The existing slitting machine is different from the conventional design. When the blade is assembled, the movable blade shaft seat moves out, and the connecting rod between the screw elevator will disengage. When the movable blade shaft seat moves in, the connecting rod docking requires manual intervention, which is complicated to operate, has low precision, and reduces production efficiency.

DETAILED DESCRIPTION
[0013] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1 、 2As shown, in this embodiment, a clutch connecting rod mechanism with a function of detecting the lifting height of the knife shaft comprises a first bracket 1 and a second bracket 6. The first bracket 1 and the second bracket 6 are fixed on the slitting frame and are arranged in the same straight line. Screw lifts 9 are respectively provided at both ends of the slitting frame, and the sliders on the two screw lifts 9 are respectively connected to the two ends of the knife shaft. A first bearing block group is provided on the first bracket 1, and a second bearing block group is provided on the second bracket 6. A first connecting rod 11 is horizontally passed through the first bearing block group, and a second connecting rod 14 is horizontally passed through the second bearing block group. One end of the first connecting rod 11 is connected to the worm gear shaft of the screw lift 9 on the corresponding side through a coupling 10, and one end of the second connecting rod 14 is connected to the worm gear shaft of the other screw lift 9 through a coupling 10. The other end of the first connecting rod 11 and the other end of the second connecting rod 14 are connected to each other through a clutch unit, which facilitates the connection between the two screw lifts 9 and improves the centering accuracy of the first connecting rod 11 and the second connecting rod 14. The first connecting rod 11 and the second connecting rod 14 are connected through the clutch unit to form a whole; the motor drives the worm shaft of the screw lift 9 to rotate, so that the screw of the screw lift rotates and the slider rises and falls along the screw, driving the two ends of the knife shaft to rise and fall synchronously, ensuring that the lifting heights of the two ends of the knife shaft are consistent.
[0015] A height detection unit is provided on the first support 1 and the second support 6, and the height detection unit detects the height of the rise and fall of the two ends of the knife shaft. The height detection unit includes a plate 3, a plate 3 is provided on the first bracket 1 and the second bracket 6 respectively, a mechanical counter 4 is provided on the plate 3, a slave pulley 5 is provided on the central axis of the mechanical counter 4, a main pulley 12 is provided on the first connecting rod 11 and the second connecting rod 14 respectively, a bushing 13 is provided on the first connecting rod 11 and the second connecting rod 14 respectively, and the bushing 13 fixes the main pulley 12. The main pulley 12 and the corresponding slave pulley 5 are connected by a belt. When the screw elevator drives the knife shaft to rise and fall, it drives the first connecting rod and the second connecting rod to rotate, and the two mechanical counters record the number of rotations of the first connecting rod and the second connecting rod, thereby reflecting the rise or fall height of the two ends of the knife shaft.
[0016] The above-mentioned clutch unit includes a first clutch 7 and a second clutch 8. The first clutch 7 is fixed to the other end of the first connecting rod 11, and the second clutch 8 is fixed to the other end of the second connecting rod 14. The first clutch 7 and the second clutch 8 are engaged with each other, so that the first connecting rod 11 and the second connecting rod 14 are fixedly connected. The first clutch 7 and the second clutch 8 are separated, so that the first connecting rod and the second connecting rod are separated, which facilitates the movement of the knife shaft seat out.
[0017] The first bearing unit consists of two spaced-apart first bearing units, while the second bearing unit consists of two spaced-apart second bearing units. Grease nipples are installed on each of the first and second bearing units. Lubricating oil is evenly distributed between the first bearing unit and the first connecting rod, and between the second bearing unit and the second connecting rod, providing lubrication and reducing failure rates.
[0018] The first and second connecting rods are connected by two clutches, and the first and second connecting rods are connected to the mechanical counter via a pulley drive. When assembling the blade, the movable cutter shaft holder is moved out. Once the blade assembly is complete, the cutter shaft height is adjusted so that the numbers displayed on the two mechanical counters match. The movable cutter shaft holder is then moved in, and the two clutches are engaged, achieving synchronous raising and lowering of the cutter shafts. This shortens the cutter shaft height detection time, improves the centering accuracy of the first and second connecting rods, and enhances production efficiency.
[0019] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
