Pushing the sliding cover (224) to slide upwards through the first air cylinder (21), placing the material completed in the steps on an L-shaped carrier plate (2244), pushing the sliding cover (224) to slide downwards through the first air cylinder (21), closing the carrying box (253), driving the carrying box (253) to rotate to a next station (12) through a first motor (23), pushing the sliding cover (224) to slide upwards through the first air cylinder (21), taking the material completed in the steps out of the carrying box (253) by the L-shaped carrier plate (2244), and taking the material completed in the steps out;

s3, painting powder

Paving the cloth cut by the step S1 below the powder drawing device (7), controlling the powder drawing die (76) to rotate through a third motor (77), enabling a required die head (763) to rotate to the upper side of the cloth, driving the powder drawing die (76) to move downwards through a seventh cylinder until the toner is stuck on the cloth, repeating the operation of the step, and drawing the powder on all the cloth transmitted in the step S2;

s4 is the same as the step S2;

s5, pruning

Trimming the cloth transmitted by the S4 along the powder line of the S3;

s6 is the same as the step S4;

s7, sewing

And (3) sewing the cloth after trimming in the step (S5) according to the working requirement of a sewing station, conveying the semi-finished product to the next station in the transmission mode of the step (S2) after sewing, and sewing the next station until the case is sewn.
