In the tension adjusting device with the anti-slip function of CN215797464U, the wire/film material forms an S shape between the two guide rollers, and the increase of the contact area provides traction force which is not suitable for the production of micro wires.

In addition, in the existing welding strip manufacturing process, in order to prevent the welding strip from slipping, a glue roller is generally used to press a driving wheel to pull the welding strip, or a mode of winding a plurality of circles on the driving wheel is adopted. Both of which are prone to deformation of the solder strip or increase in yield strength of the solder strip.
