the bottom of the sealing strip (571) is attached to the tensioning sheet (55), and the top of the sealing strip (571) is attached to the flexible strip (541).

3. The intelligent centralized oil lubrication system of claim 2,

the flexible strip (541) is provided with a plurality of strip-shaped inserting grooves (542), and the tops of the arc-shaped pieces (56) are clamped in the inserting grooves (542).

4. The intelligent centralized oil lubrication system of claim 3,

the insertion grooves (542) in the same mounting chamber (54) are not communicated with each other.

5. The intelligent centralized oil lubrication system of claim 4,

the arc-shaped sheet (56) bulges outwards, and the upper part of the arc-shaped sheet (56) can be attached to the side wall of the mounting chamber (54).

6. The intelligent centralized oil lubrication system of claim 5,

the side wall of the arc-shaped sheet (56) is provided with a guide arc (561).

7. The intelligent centralized oil lubrication system of claim 6,

the vertex angle of the tensioning piece (55) is provided with an attaching arc (551), and the curvature of the attaching arc (551) is equal to that of the guide arc (561).

8. The intelligent centralized oil lubrication system of claim 7,

the top of the tensioning sheet (55) is welded with a honeycomb plate.

9. The intelligent centralized oil lubrication system of claim 8,

an upper cover plate (58) is welded at the top of the floating plate (5).

10. The intelligent centralized oil lubrication system of claim 9,

one end of the piston sleeve (42) is arranged outside the lubricating tank (1), the other end of the piston sleeve (42) is arranged inside the lubricating tank (1), and the piston sleeve (42) faces the eccentric disc (3);

a first accommodating bin (421) and a second accommodating bin (422) are formed in the piston sleeve (42), the inner diameter of the second accommodating bin (422) is larger than that of the first accommodating bin (421), and the first accommodating bin (421) is arranged at one end, close to the eccentric disc (3), of the piston sleeve (42);

an oil inlet hole (423) is formed in the outer wall of the piston sleeve (42), the oil inlet hole (423) is formed in the outer wall of the second accommodating bin (422), and the oil inlet hole (423) is communicated with the second accommodating bin (422);

the sealing ring (43) is sleeved on the outer wall of the end part of the piston rod (41), and the outer diameter of the sealing ring (43) is the same as the inner diameter of the second accommodating bin (422); wherein

When the eccentric disc (3) axially rotates to sequentially push the piston rod (41) to slide outwards, the piston rod (41) drives the sealing ring (43) to slide outwards so as to spray lubricating oil outwards;

when the piston rod (41) slides inwards and passes through the oil inlet hole (423), lubricating oil is injected into the second accommodating bin (422) through the oil inlet hole (423);

when the piston rod (41) moves inwards continuously until the sealing ring (43) slides into the inner wall of the first accommodating bin (421) through the second accommodating bin (422), the sealing ring (43) can push lubricating oil to flow from the second accommodating bin (422) to the inner wall of the first accommodating bin (421).
