Description

Four-roller feeder

Technical Field

The utility model relates to the field of mechanical equipment, in particular to four-roller feeder.

Background

In the production process, the metal strip is often required to be punched by a punch press so as to change the shape of the metal strip to meet the processing requirements of different subsequent products. Some metal bands which are not subjected to stamping processing are mostly stored on the roll shaft in order to facilitate storage and feeding during processing, and the metal bands are only required to be pulled out from one end through a power device to achieve feeding when the metal bands are used.
