Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for producing electric wires and cables, in particular to a steel strip pay-off reel for an armoring machine used for producing cables. Background Art

[0002] Armored cables are cables with an armor layer added to the outer sheath to increase the mechanical strength of the cable and improve its anti-corrosion ability. Armored cables can be laid in any way and are more suitable for direct burial in rocky areas. They are widely used in places susceptible to mechanical damage and erosion. Armored cables are divided into steel belt armored cables and steel wire armored cables.

[0003] At present, the production of steel belt armored cables is achieved by winding the steel belt around the cable using a steel belt wrapping head. The steel belt used in production is mostly purchased in the form of rolls, which do not have a reel and cannot be directly fixed on the steel belt wrapping head for unwinding. Before production, it is first necessary to use special winding equipment to wind the steel belt on the reel that matches the wrapping head, and then use the reel to fix the steel belt on the wrapping head. The winding process is time-consuming and labor-intensive, with low work efficiency and high labor intensity. Utility Model Content

The tension spring 9 is an annular spring. One annular spring pulls four sector-shaped sliders 6 together. The inner arc surface of the sector-shaped slider 6 is inclined to form an inclined surface 10. The inclined surface on the outer side of the wedge ring 11 is pressed on the inner arc surface of the sector-shaped slider 6. The inner ring 1 is connected to the reel 12 through a key. The fixed baffle 13 is fixed on the reel 12 at the rear side of the inner ring 1. The movable baffle 15 is movably sleeved on the reel 12 at the front side of the inner ring 1 and fixed by the clamping nut 16 threadedly assembled on the reel 12. The fixed baffle 13 and the movable baffle 15 are both perpendicular to the reel. The steel strip is rolled into the reel formed by the sector-shaped slider, and the fixed baffle and the movable baffle are used to limit the axial position.

[0026] A radial dovetail guide rail 4 is arranged on the front end face of the annular boss by means of a screw 5, and a dovetail groove 7 adapted to the dovetail guide rail 4 is arranged on the rear end face of the fan-shaped slider 6, that is, the dovetail guide rail and the dovetail groove are perpendicular to the reel, and the fan-shaped slider 6 can slide radially along the dovetail guide rail 4.
