When adjusting, the turntables 10 at both ends are rotated to drive the studs 9 to rotate and move downward, thereby driving the slide plate 6 to move downward, and driving the coating roller 7 to move downward to adjust the distance between it and the coating drive roller 11, and adjust the distance to a suitable thickness for the coated packaging bags.

[0030] The end of the film sleeved on the film spreading roller 3 is passed through the auxiliary roller 4 to the front side of the lower end and then adhered to one end of the packaging bag. The motor 12 drives the film transmission roller 11 to rotate counterclockwise. With the cooperation of the film pressing roller 7, the film between the film pressing roller 7 and the film transmission roller 11 is pressed and laminated with the packaging bag. The motor 2 14.2 rotates to drive the rotating roller 14.1 to rotate, thereby driving the conveyor belt 13 to move and convey the laminated packaging bag.

[0031] The fan 18 is started to supply air to the heating box 17, and the external air enters from the filter cover 19.1. After the dust is adsorbed by multiple dust removal filter cartridges 19.3, the clean air is sent to the heating box 17 for heating. At the same time, the dust can be removed from the surrounding environment of the coating to prevent dust from being adsorbed on the coating or packaging bags and affecting the coating quality. The air slightly heated by the heating box 17 is transmitted to the lower end of the air outlet 22 through the air supply pipe 21, and the coated plastic bags transmitted by the conveyor belt 13 are slightly heated by hot air to make the adhesion between the coating and the packaging bags stronger. Then the cylinder 25.3 is started to drive the pressing roller 24 to move downward. When the conveyor belt 13 transmits the coated packaging bags blown by hot air after coating to the lower end of the pressing roller 24, the pressing roller 24 presses the coated packaging bags again to fully ensure the coating effect between the coated packaging bags.
