s3, then, after the air pump (55) is started, air in the sealed shell (51) is sucked through the exhaust pipe (54), at the moment, the second air inlet pipe (53) is blocked by the blocking block (61), therefore, the sealed shell (51) pumps outside air through the first air inlet pipe (52), then, the outside air enters the air pump (55) through the exhaust pipe (54), and at the moment, the end part of the sliding pipe (75) is blocked by the hollow shell (81), so that the air is output through the shunt pipe (56);

s4, after the second driving motor (78) is started, the hollow screw rod (71) is driven to rotate through the second driving gear (79), the threaded sleeve (72) is driven to move to the right continuously when the hollow screw rod (71) rotates, the threaded sleeve (72) pushes the hollow shell (81) when moving, meanwhile, the connecting sleeve ring (66) is driven to move, when the hollow shell (81) moves to the right, the compressed second spring (76) is reset gradually, the end part of the sliding tube (75) is always attached to the inner wall of the hollow shell (81) under the pushing of the second spring (76), when the connecting sleeve ring (66) moves, the sliding rod (62) is pushed through the connecting rod (65) and the connecting block (64), and then the blocking block (61) moves to the right on the inner side of the sealing shell (51);

s5, when the right movement distance of the threaded sleeve (72) reaches a first threshold value, the sealing block (61) is pushed by the sliding rod (62) to release the sealing of the second air inlet pipe (53), meanwhile, the sealing of the first air inlet pipe (52) is completed, at the moment, air in the hollow rotary roller (31) is sucked into the sealing shell (51) through the second air inlet pipe (53) and the hollow shaft (35), outside air is sucked into the hollow rotary roller (31) through the air inlet channel (34), when the right movement distance of the threaded sleeve (72) reaches a second threshold value, the second spring (76) is completely reset, then in the process that the threaded sleeve (72) continues to move rightwards, the hollow shell (81) does not close the end part of the sliding pipe (75), air flow output by the shunt pipe (56) enters the sliding pipe (75) through the hollow screw (71), is output to the interior of the hollow shell (81) through the sliding pipe (75), and is finally horizontally sprayed out through a plurality of air exhaust channels (83);

s6, when the right movement distance of the threaded sleeve (72) reaches a third threshold value, the cutting knife (82) cuts off the optical film (4) under the pushing of the hollow shell (81), at the moment, the part, which is not coated, of the optical film (4) is separated, then the second driving motor (78) drives the second driving gear (79) to rotate reversely, further the triggering mechanism (6), the driving mechanism (7) and the cutting mechanism (8) are reset, at the moment, under the adsorption action of air flow sprayed from the exhaust channel (83) and the air inlet channel (34), the cut-off optical film (4) is tightly attached to the surface of the bearing sleeve (33) and is adsorbed, and then the bearing sleeve (33) is rolled under the rotation action.
