s2, feeding: controlling a fourth motor (40) to enable the fourth motor (40) to drive a transmission mechanism (39) to feed, wherein the transmission mechanism (39) drives the plastic to be fed into a feeding channel (49), and in the feeding process, a compression roller (38) can flatten the plastic bag;
s3, folding for one time: when a plastic bag enters the feeding channel (49), the first motor (16) is controlled, so that the first motor (16) drives the rotary head (15) to rotate for one circle, the rotary head (15) drives the rotary disc (13) to rotate for one circle, the rotary disc (13) drives the pull rod (11) to pull for one time, the pull rod (11) drives the first folding plate (10) to move for one time, and then the plastic bag can be folded for one time, and is positioned at the position where the longitudinal folding channel (48) and the transverse folding channel (29) are staggered;
s4, secondary folding: controlling a second motor (25) to enable the second motor (25) to drive a crank (21) to rotate for a circle, and enabling the crank (21) to drive a second folding plate (27) to complete primary stretching through a connecting rod (19) so as to complete secondary folding of the plastic bag, and enabling the plastic bag to be located at the top of the pressing table (2);
s5, flattening and pressing: before feeding, the cam (33) is rotated through the third motor (31) to jack up the pressing plate (3), when a plastic bag is folded twice and guided into the top of the pressing table (2), the third motor (31) is controlled to drive the rotating shaft (32) to rotate, so that the cam (33) rotates, the jacking effect on the pressing plate (3) is cancelled, and the pressing plate (3) presses the folded plastic bag through the action of the spring (4);
s6, taking materials: after the plastic bag is compressed for a period of time, the third motor (31) is controlled to drive the rotating shaft (32) to rotate, and then the cam (33) is rotated, so that the cam (33) upwards jacks the compression plate (3), and the folded and compressed plastic bag can be taken out.
