The three-dimensional knitting machine with the lubrication system of claim 8, wherein: the up end of driver plate (4) is equipped with spiral oil trap, the spiral of oil trap is revolved to rotating opposite direction with driver plate (4), after fluid is promoted to driver plate (4) up end by the helicla flute in the through-hole, the centrifugal force that rotatory driver plate (4) produced gets rid of driver plate (4) with fluid and spindle (2) handing-over department lubricates, fixed axle (3-1) center department is collected with fluid to the oil trap on rethread driver plate (4) terminal surface, avoids too much fluid to throw away the pollution establishment thing.
10. A lubrication method for a three-dimensional knitting machine using a lubrication system according to any of the preceding claims, characterised by the steps of:
when the three-dimensional knitting machine normally operates, the driving plate (4) is driven to rotate at a constant speed; the driving plate (4) and the fixed shaft (3-1) generate relative motion, and because the inner wall of the through hole at the circle center of the driving plate (4) is provided with a spiral groove, the spiral motion can generate micro lift force, so that a small amount of oil is sucked to the end surface of the driving plate (4) through the spiral groove, the end surface of the driving plate (4) and the fixed shaft (3-1) are lubricated, and the oil is collected in a way of carving an oil collecting groove to prevent the oil from being thrown out of the woven fabric to be polluted;
the oil injection mechanism (5) is arranged at the position where the spindle (2) is reversed when in work, the spindle (2) periodically impacts a pulley (5-10) of the oil injection mechanism (5) when in operation, so that a piston rod (5-9) extrudes a spring (5-8) in a cavity (5-3), the compression in a rodless cavity of the cavity (5-3) is reduced, pressure is generated, lubricating oil is sprayed to the joint of the spindle (2) and the drive plate (4) through the atomized oil spray nozzle (5-1), and the abrasion of the spindle (2) during reversing is effectively reduced; the oil injection mechanism (5) enables the volume in the rodless cavity to be enlarged through the restoring force of the spring (5-8) to generate negative pressure, and lubricating oil is supplemented through the oil suction pipe (5-6).
