Technical Field

The invention relates to tension on-line detection equipment, in particular to a steel cord outer winding paying-off tension on-line detection control device.

Background

The outer winding machine is an important device in steel cord production equipment and is used for winding a thin monofilament on the surface of a cord so that the cord is more easily attached with glue. When the outer winding machine is used for producing products, the rotating speed of an outer winding main shaft is high and is normally more than 10000r/min, an outer winding head is screwed on the outer winding main shaft, the outer winding head is used for uniformly winding an outer winding wire with 0.15mm on a strand produced in the previous process, how to control the uniform winding of the outer winding wire on a cord and ensure that the outer winding wire with 0.15mm is not broken at the rotating speed of more than 10000r/min in the production process is controlled by the tension of the outer winding wire, therefore, whether the tension control of the outer winding wire is proper or not is particularly important, the uneven twisting can be caused once the tension of the outer winding wire is small, and the phenomenon of breaking the outer winding wire can be caused once the tension of the outer winding wire is large. This problem also has the following adverse effects: 1. the first yield of the product is reduced; 2. the labor intensity of the staff is increased; 3. the loss is increased; 4. the effective running rate of the machine tool is reduced, the maintenance is frequent, and the complaints of maintenance personnel are more; 5. there is a certain quality safety hidden trouble.
