in the first case, when the aluminum plate cold rolling unit and the object carrying plate (2) vibrate downwards as a whole, the aluminum plate cold rolling unit and the object carrying plate are downwards transmitted to the fixed block (14) through the double-lug seat and the hinging rod (30), the fixed block (14) drives the piston slide rod (12) to slide along the piston sleeve (11) to drive the piston spring (13) to deform, and the piston slide rod (12), the piston sleeve (11) and the piston spring (13) jointly form a resistance spring effect;
meanwhile, the whole downward acting force is dispersed to a T-shaped seat (27), the T-shaped seat (27) is transmitted to a T-shaped connecting plate (26) through a second connecting rod (28), and then is transmitted to an L-shaped sliding plate (22) through a first connecting rod (25), so that the first connecting rod (25) and the second connecting rod (28) are in a V-shaped shape, and due to the combined action of a plurality of torsion springs (29), the first connecting rod (25) is driven to recover towards an initial state, and the whole shock absorption stability of an aluminum plate cold rolling unit and an object carrying plate (2) is further ensured;
secondly, when the aluminum plate cold rolling unit and the carrying plate (2) vibrate forwards or backwards as a whole, the double-lug seat and the hinging rod (30) play a role of a fulcrum, the carrying plate (2) is driven to incline forwards or backwards, and the L-shaped sliding plate (22) and the T-shaped sliding block (23) are driven to slide along the U-shaped clamping plate (24) through the T-shaped seat (27), the second connecting rod (28), the T-shaped connecting plate (26) and the first connecting rod (25) at one side;
when the L-shaped sliding plate (22) slides forwards and backwards, the H-shaped connecting plate (21) drives the fixed lug seat (15) and the fixed block (14) to rotate and incline, the limiting swing arm (20) drives the L-shaped swing arm (18) to swing, the L-shaped swing arm (18) swings in a limited range under the limiting effect of the limiting stop pin (17) to drive the tension spring (19) to deform, and the bottom plate (1), the object carrying plate (2) and the aluminum plate cold rolling unit keep a relative dynamic balance state.
