Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and more particularly to a grabbing mechanism for coil packaging. Background Art

[0002] At present, in order to facilitate the transportation and storage of rolled materials, it is often necessary to wrap the outer surface and both ends of the rolled materials with protective cardboard to prevent the outside of the rolled materials from being worn or sticky, thereby protecting the outside of the rolled materials.

[0003] Based on the above, the inventors found that when packaging the two ends of the coil, workers are usually required to manually place the protective cardboard at the end position of the coil and then fix it with glue. This operation not only increases the workload of the workers, but also has a relatively low packaging efficiency. Therefore, in view of this, the existing structure is studied and improved to provide a gripping mechanism for coil packaging, in order to achieve a more practical purpose. Utility Model Content
