Description

Technical Field

[0001] The present application relates to the technical field of steel cord production, and in particular to a real-time speed measuring device for a steel cord stranding machine. Background Art

[0002] At present, steel cord is a skeleton material used for tires. The production process of steel cord needs to go through a series of processes such as rough drawing, medium drawing, medium drawing heat treatment, electroplating, wet drawing, and stranding. Among them, the steel wire is twisted into steel cord by a stranding machine. During the twisting process of the steel wire, the steel wire is driven by the main shaft of the stranding machine to move in a uniform circular motion, and at the same time is driven by the traction device to move forward at a uniform speed, so that the steel wire is in a cylindrical spiral state in the strand and in the cord. The steel wire is twisted into strands along the conductor tube through the pre-deformer to the twisting point, and then guided by the traction wheel, and wound on the take-up I-shaped wheel through the straightener.

After the position of the mounting bracket is adjusted, the fastening screws need to be tightened. This operation is cumbersome, making it inconvenient to adjust the position of the mounting bracket.
