Description

Technical Field

[0001] The invention relates to a braiding machine and a braiding assembly thereof, in particular to a braiding assembly of a steel wire braiding machine and a steel wire braiding machine using the braiding assembly. Background Art

[0002] Most of the existing wire braiding machines are 8-shaped braiding machines, and the front and rear spindles are braided in a circular motion around the 8-shaped track. This wire braiding machine has the following disadvantages during use: 1. Since the braiding machine adopts the principle of the 8-shaped circular track, its mechanical operation has large resistance and low speed, large mechanical consumption and greatly reduced work efficiency; 2. During braiding, the spindle keeps moving up and down on the 8-shaped track. When the spindle runs to the upper rotation, the spindle is far away from the braiding point. At this time, the spindle tension spring is compressed, the line is released, and the tension is increased. When the spindle runs to the lower rotation, the spindle is close to the braiding point, the tension spring is extended, and the tension is reduced. As a result, the tension of the wire harness woven on the tube body is unstable and inconsistent, which seriously affects and reduces the quality of the woven product; 3. The wire harness released from the spindle to the tube body of the traditional braiding machine constantly moves freely to find the braiding point. Therefore, the position of the braiding point of the wire harness woven on the tube body is inaccurate and uneven, which can easily cause the bearing pressure of the tube body to decrease and reduce the pulse number of the tube body, seriously affecting the quality of the tube product.
