The apparatus for opening bulk aramid pulp according to claim 4, wherein: The two sides of the oil storage box (34) are vertically provided with independent oil pipes (35), an oil inlet hole (39) is formed in the lower side of the oil storage box (34) and is connected with the independent oil pipes (35), a downward pushing piston (38) is arranged in the independent oil pipe (35) and is located above the oil inlet hole (39), a one-way valve (37) is arranged in the independent oil pipe (35) and is located below the oil inlet hole (39), a reset spring (40) is arranged between the downward pushing piston (38) and the one-way valve (37), an access hose (42) is arranged in the access mouth (41) of the upper mounting module (6) and is connected with the lower end of the independent oil pipe (35), the upper ends of the two independent oil pipes (35) penetrate the oil storage box (34) and are connected with a shunt pipe (36), one side of the shunt pipe (36) is connected with a switching air pipe (33), and one end of the switching air pipe (33) is connected with the three-way joint (26).

6. A method of using the bulk aramid pulp opening device according to any one of claims 1-5, characterized in that, The method comprises the following steps: Step one: when in use, the two spline roller (3) carries out preliminary crushing treatment on the block-shaped aramid pulp conveyed by the conveying belt, so that the block-shaped aramid pulp keeps a relatively flat state and enters between the auxiliary compression roller (4) and the taker-in (5), and then is subjected to preliminary opening under the dispersion of a plurality of combined taker-in blades (15) on the taker-in (5), so as to reduce the winding condition of subsequent fine opening. Step two: when the tines of the combined tines (15) are damaged, the two end flaps (20) can be moved away from the tine cylinder (12), and then the assembled screw rod (18) is loosened and disassembled. At this time, the combined tines (15) can be removed from the tine cylinder (12) for replacement. The installation is inserted and assembled with screw rod (18) limiting connection. The modularization of tine cylinder (12) can accelerate the convenience of maintenance and replacement; Step three: when the tines of the combined tines (15) are wound, control the worm (27) to control the anti-winding roller (21) to rotate, so that the anti-winding blades (31) of the one side installation strip (30) contact the side of the combined tines (15), cut the aramid pulp fiber wound on the combined tines (15), so that it is easy to separate from the combined tines (15). Three installation strips (30) are used intermittently and alternately; Step four: when the anti-winding blades (31) cut the aramid pulp fiber wound on the combined tines (15), the three-way joint (26) is connected to high pressure gas. The high pressure gas blows to the position of the anti-winding blades (31) through the center gas groove (28) and the blowing groove (32), and cuts the loose aramid pulp fiber to blow off, while avoiding winding the anti-winding blades (31), and cooling the anti-winding blades (31) and the combined tines (15); Step five: after the high pressure gas enters the center gas groove (28), when the air pressure continues to increase, the high pressure gas will enter the two independent oil pipes (35) from the adapter pipe (33) and the shunt pipe (36), so as to make the push down piston (38) descend, extrude the lubricating oil between the push down piston (38) and the one-way valve (37) from the position of the one-way valve (37), and drop on the first support shaft (7) in the two installation modules (6) under the action of gravity, and then fill in the bearing groove (8) under the centrifugal shaking action of the lubricating oil, improve the rotation stability of the first support shaft (7) in the installation module (6).
