s1, enabling double-layer plastic films to sequentially penetrate between the first guide roller (32) and the second guide roller (33) and between the first roller shaft (3) and the second roller shaft (4), enabling the double-layer plastic films to be located below the air injection pipe (30), enabling the starting motor (7) to drive the first roller shaft (3) to rotate, enabling the first roller shaft (3) to drive the first roller shaft (3) to synchronously rotate through a chain, and enabling the conical head (20) to penetrate through the double-layer plastic films;
s2, injecting glue into the second annular cavity (15) through the liquid inlet pipe (14), enabling the glue to flow into the first annular cavity (11) through the liquid guide pipe (9), then enabling the glue to flow into the branch pipe (16) from the liquid guide pipe (12), conveying the glue into the liquid collection pipe (22), enabling the glue to flow out of the straight pipe (18) from the conical head (20), and enabling the glue flowing out of the outer surface of the conical head (20) to bond the penetrated double-layer plastic film part;
s3, conveying hot air with the temperature of 30-60 ℃ into the air injection pipe (30) by the air heater (31), blowing the hot air to the double-layer plastic film by the air injection pipe (30), and drying the glue at the penetrating part of the double-layer plastic film;
and S4, rolling the double-layer plastic film from the outside, wherein the rolling speed is kept consistent with the rotating speed of the first roller shaft (3).
8. A bag making method according to claim 7, characterized in that when adjusting the length of the bag making, the fastening bolts (28) are screwed off obliquely and the corresponding slide rods (25) are pulled, so that the slide rods (25) drive the straight pipe (18) to move along the guide cylinder (17) through the connecting rod (23), thereby conveniently controlling the different conical heads (20) to protrude out of the first roll shaft (3), the distance between two adjacent protruding conical heads (20) represents the corresponding bag making length, and after the adjustment is completed, the fastening bolts (28) are screwed to fix the slide rods (25).
