Description

Technical Field

[0001] The utility model relates to the technical field of adhesive product production equipment, in particular to a traction mechanism of a continuous die-cutting machine. Background Art

[0002] Die-cut products are widely used in automobile manufacturing and electronics industries. With the rapid development of technology, the die-cutting process has gradually expanded from traditional die-cutting of printed materials to the production of auxiliary materials for electronic products. For example, the die-cutting process is used to prepare adhesive products and film products for electronic product bonding, insulating materials, dustproofing, shockproofing, insulation, and shielding.

[0003] In the prior art, adhesive products are mostly cut using die-cutting machines. Traditional die-cutting machines perform die-cutting by closing the upper and lower molds. However, when the strip material is pressed down, the material will be deformed, resulting in deformation of the cut, which affects the die-cutting quality.

[0004] Therefore, how to provide a traction mechanism for a continuous die-cutting machine to solve the problems existing in the prior art is of great significance to its application. Utility Model Content
