Description

Technical Field

[0001] The invention relates to the technical field of cable surface drying, in particular to a positioning device for an adjustable top cone of a stranding machine. Background Art

[0002] In the cable manufacturing process, several single wires need to be twisted together according to the process requirements and collected on a take-up wheel. Before starting to twist, the empty take-up wheel should be installed on the equipment, and the take-up wheel should be removed from the equipment after the wire wheel is full. The take-up wheel is installed on two top cones of the equipment, one of which is an active fixed top cone, which is driven to rotate by the internal transmission mechanism of the equipment and cannot move axially; the other top cone is a driven top cone, and its built-in bearing is installed on a top cone shaft and driven by the take-up wheel, and can be driven by the drive mechanism to move axially back and forth, so as to be used for loading and unloading the take-up wheel. However, the existing drive mechanism does not have a reliable locking structure, which makes the top cone at risk of sliding, which leads to safety hazards of the take-up wheel.
