Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, and in particular to a cylinder-adjustable pressure roller device. Background Technology

[0002] Pull-head pressure roller structures are widely used in roll material processing. These structures achieve pressure engagement between the pull-head roller and the pressure roller, preventing slippage of the roll material during the printing process. Currently, pull-head pressure roller structures in roll material processing primarily employ spring adjustment. The pressure between the pull-head roller and the pressure roller is adjusted manually by regulating the spring force. However, this method of adjusting the pressure is inaccurate, inconvenient to operate, and prone to poor printing results due to low manual adjustment precision. Utility Model Content
