It is mainly to solve the technical problems that the existing metal wire coil basically does not have an ideal packaging and packaging methods. The main point of its technical solution is that the inner diameter of the packaging sleeve made of fiber woven fabric matches the shape of the wire coil, the length of the packaging sleeve is larger than the total length of the metal wire coil bundled, and both ends of the packaging sleeve are locked The device is characterized in that the locking device is a fixed lock at one end and an inactive lock at the other end or an active lock at both ends. It can effectively semi-closed or fully enclosed metal wire coils and is made of flexible and moisture-proof materials. Therefore, the metal coils packaged by the utility model can be effectively handled during handling and loading and unloading. Anti-collision, and the packaging effect is good, it has pest control, moisture-proof function and temperature deformation, high strength, good toughness and other characteristics. Sovereignty item 1. A packing sleeve for coil packaging of metal wire coils, characterized in that: the inner diameter of the packing sleeve (3) made of fiber woven cloth matches the shape of the metal wire coil (2), and the packing sleeve The length of (3) is greater than the total length of the bundle of metal wire coils after baling, and the two ends of the packaging sleeve (3) are provided with a locking device, wherein the locking device is a fixed lock at one end or an inactive lock at the other end or both ends Are all active locks.
