AI Technical Summary
Existing metal mesh rolling mills are prone to springback during one-time rolling, requiring multiple rolling cycles to achieve flatness, resulting in low efficiency.
The system employs a bracket, a pressing assembly, and a chain drive system. The tightness between the pressure roller and the roller shaft is controlled by elastic pressure plates and adjusting nuts. Combined with the synchronous rotation of three sets of roller shafts and the design of tensioning wheels, it achieves continuous flattening in three stages.
It improves the flatness and transmission stability of the wire mesh, reduces wear and uneven transmission, and increases production efficiency.
