Description
Technical Field
[0001] The invention relates to the technical field of armored cable manufacturing, and in particular to a steel strip edge glue-coated spiral wrapping device. Background Art
[0002] Armored cables usually use a double-layer spiral gap wrapping process, and after armoring, a plastic sheath is extruded to protect the steel belt to prevent corrosion. Double-layer spiral gap wrapped armored cables have excellent compressive resistance, can resist external impact and positive pressure, and can effectively protect the cable core and avoid mechanical damage. Since there is a layer of steel belt between the gap and the overlap of the double-layer armor, which is equivalent to a step, when the outer sheath is produced, the sheath is easily formed at the step after longitudinal stretching, resulting in the thinnest point of the sheath thickness on the step. When the armored cable is used, the bending process may cause the sharp corners of the outer steel belt and the thinnest point of the sheath to be subjected to excessive force. When the external environment temperature, humidity, etc. change, it is easy to cause the sheath to crack. In order to solve this problem, a layer of wrapping tape is usually used to wrap the cable armor outside, the purpose is to increase the thinnest point of the sheath thickness and wrap the edges and corners of the steel belt to avoid directly piercing the outer sheath structure.
