Description

A kind of aluminum die pull sheet strapping machine

technical field

The invention belongs to the technical field of strapping machine structures, and in particular relates to an aluminum die pull tab strapping machine.

Background technique

At present, the manufacturers who produce aluminum die pull tabs still need to manually tie them when they need to be bundled and transported after production, which is time-consuming and labor-intensive, and requires a lot of labor. And because of the sharp shape caused by the function endowed by the aluminum mold pull tab itself, it is not easy to operate when manually bundling, and there may be a risk of scratches and cuts.

The existing strapping machines on the market include automatic tape strapping machines, automatic strapping strapping machines and automatic steel strapping machines. The automatic tape strapping machine is limited by the fact that the material used for strapping is too light and thin, and it is not wear-resistant, which will cause the strapping failure or even loosening due to the sharp edge of the aluminum die pull tab during transportation, which brings great difficulties to transportation and handling. Because the packaging of the automatic strapping machine is too loose, it is easy to fall off and loose when bundling small-volume workpieces such as aluminum die pull tabs, and the reliability is low. The area of the material steel belt used by the automatic steel strapping machine for strapping is too large, and it cannot be reliably strapped when it encounters the complex edge of the aluminum mold pull tab, and it will fall off from both ends during transportation.
