Description

Aluminum die pulling-on piece strapping machine

Technical Field

The utility model belongs to the technical field of the strapper structure, especially, relate to an aluminium mould pulling-on piece strapper.

Background

At present, manufacturers for producing aluminum die pull tabs still need to manually tie up the aluminum die pull tabs when the aluminum die pull tabs are produced and need to be tied up for transportation, time and labor are wasted, a large amount of labor needs to be consumed, labor cost needs to be increased for a production side, resource waste is caused, and the working efficiency is low and the labor intensity is high. And the aluminum die pull tab is not easy to operate and may be scratched or cut due to the sharp appearance caused by the imparted function of the aluminum die pull tab itself when manually bundling.

The strapping machines available on the market include automatic tape strapping machines, automatic packing-tape strapping machines and automatic steel-tape strapping machines. The automatic tape binding machine is limited in that the binding material is too light and thin and is not wear-resistant, and the binding fails or even loosens due to the sharp edge of the aluminum die pull tab during transportation, thereby bringing great difficulty to transportation and handling. The automatic strapping machine has low reliability because the package is too loose and the automatic strapping machine is easy to fall off and loose when a small-volume workpiece such as an aluminum die pull sheet is strapped. When the automatic steel strip bundling machine is used for bundling, the area of a used material steel strip is too large, reliable bundling cannot be carried out when the edge of an aluminum die pull sheet is complex, and the material steel strip can fall off from two ends in the transportation process.

The existing strapping machine is not suitable for strapping and packaging the aluminum die pull piece.
