8. A method for processing a sleeve vent based on the sleeve vent folding device of claim 7, wherein the processing method comprises the following steps of:

s1, placing a sleeve fork cutting piece (10) on a machine table (100), wherein a first lifting plate (400) is flush with a first table top (201) and a second lifting plate (400) is lower than the first lifting plate (400), a sword-shaped feeding piece (11) of the sleeve fork cutting piece (10) covers a feeding piece discharging groove (302) area, a discharging piece (12) of the sleeve fork cutting piece (10) covers a discharging piece discharging area (202), and the discharging piece (12) is adsorbed by the discharging piece discharging area (202) and an air suction hole (203) of the first lifting plate (400);

s2, the feeding sheet shaping plate (320) descends and locally presses the sword-shaped feeding sheet (11) into the feeding sheet discharging groove (302);

s3, the lower material sheet folding plates (210) extend upwards out of the first table top (201) and slide towards the lower material sheet discharging area (202) to fold the lower material sheets (12) to form inner folds of the lower material sheets (12), and each upper material sheet folding plate (310) sequentially slides towards the upper material sheet discharging groove (302) to fold the sword-shaped upper material sheets (11) to form inner folds of the sword-shaped upper material sheets (11);

s4, the overturning mechanism (330) drives the feeding sheet folding mechanism (300) to overturn towards the discharging sheet folding mechanism (200);

s5, the second lifting plate (500) descends to be lower than the first table top (201), the second lifting plate (400) ascends to be flush with the first lifting plate (400), the garment piece (20) with the fork seam (21) in the middle is connected with the sleeve fork cut piece (10) in a plug-in mode, and the garment piece (20) on one side of the fork seam (21) covers the upper surface of the blanking piece (12);

s6, the first lifting plate (400) and the second lifting plate (500) synchronously lift to be flush with the first table top (201), and the lower material sheet folding plate (210) is retracted to be flush with the first table top (201);

s7, the overturning mechanism (330) drives the feeding sheet folding mechanism (300) to overturn to the upper surface of the discharging sheet folding mechanism (200) again so as to attach the inner flanging side of the sword-shaped feeding sheet (11) to the inner flanging side of the discharging sheet (12) to form a sword-shaped sleeve fork with the right side facing upwards;

s8, each feeding sheet folding plate (310) is retracted, and then the second table top (301) slides away from the direction of the sword-shaped sleeve fork.

9. The method of forming a cuff as recited in claim 8, further comprising sewing and connecting a right-side-up sword-shaped cuff to a panel (20) as follows:

s9, pressing a transfer mold frame (500) down on the upper surface of the sword-shaped sleeve vent, and then drawing out a feeding sheet shaping plate (320) from the sword-shaped sleeve vent;

s10, transferring the sword-shaped sleeve vent to a sleeve vent sewing machine position by a transferring mold frame (500), and sewing and connecting the sword-shaped sleeve vent with the right side upwards with the garment piece (20) by a sleeve vent sewing machine.
