[0002] In the field of metal plate processing, plate rolling machines are key equipment for realizing plate bending and forming, and are widely used in mechanical manufacturing, shipbuilding, chemical industry and other industries. Traditional plate rolling machines usually include a frame, a transmission roller assembly, a pressure roller assembly, and a carrier roller assembly, etc. basic structure, through the coordinated action of the transmission roller assembly and the pressure roller assembly, pressure is applied to the plate to cause plastic deformation, thereby achieving the purpose of rolling.

[0003] However, the existing plate rolling machine has many problems in actual use. In terms of lubrication and cleaning, the traditional lubrication method mostly uses simple oil dripping lubrication, which cannot achieve uniform distribution and efficient use of lubricating oil, and it is difficult to clean the oxide and impurity particles on the surface of the pressure roller in time, which not only affects the rolling quality of the plate, but also accelerates the wear of the pressure roller, shortening the service life of the equipment. At the same time, the lubrication system and cooling system of the existing plate rolling machine are independent of each other, which cannot realize the effective integration and utilization of resources, resulting in high energy consumption of the equipment.

[0004] In terms of transmission system, the transmission structure of some plate rolling machines is complex, and the synchronization is poor, which is easy to cause the transmission roller assembly to rotate out of sync, thereby affecting the precision and stability of plate rolling.
