Description

Technical Field

[0001] The utility model relates to the technical field of metal coils, and more specifically, to a precision wrapping machine for metal coils. Background Art

[0002] There are various types of metal coils. For example, galvanized aluminum coils are strips of galvanized aluminum materials cut from galvanized aluminum plates by a slitting machine and wound into coils. Based on the needs of packaging or transportation, a layer of packaging tape needs to be wound around their surfaces.

[0003] After retrieval, the utility model patent with the publication number of CN210822893U discloses a precision wrapping machine for metal coils, which includes a gantry frame, a mounting seat and a base arranged on the gantry frame. A winding mechanism and a packaging tape are arranged on the mounting seat. A placement groove for limiting the metal coil is opened in the middle of the base. A driving roller and a second driving component are arranged in the placement groove. A limiting rod group for limiting the metal coil is also arranged on the base. A jacking component is arranged in the placement groove. The jacking component includes a rotating shaft, a push rod fixedly connected to the rotating shaft along the radial direction of the rotating shaft, and a third driving component for driving the rotating shaft to rotate. The rotating shaft is rotatably connected to the placement groove and has the same axial direction as the metal coil. The rotating shaft and the push rod are both located between two rotating shafts. After the packaging tape completes the packaging of the metal coil, the third driving component drives the rotating shaft to rotate, and the push rod on the rotating shaft jacks up the metal coil towards the discharge end of the base, that is, the packaging of the metal coil is completed.

[0004] However, the above patent still has the following deficiencies: After the metal coil is jacked out by the push rod, the metal coil rolls down through a slope. Although the speed of the metal coil is slowed down by setting a buffer, due to the generally heavy weight of the metal coil and its large rolling inertia, there is a possibility that the metal coil rushes out, which is relatively dangerous; it is also not convenient to place the metal coil on the winding station. For this reason, we propose a precision wrapping machine for metal coils. Summary of the Utility Model
