Two second feeding rollers 22 are slidably connected to the lower surface of the second crossbar 15.

[0026] Two sets of first vertical plates 9 are symmetrically fixedly connected to the left and right ends of the upper surface of the base 1. A first movable plate 10 is slidably connected between two adjacent first vertical plates 9. Limiting rollers 8 are rotatably connected to the lower surfaces of the two first movable plates 10. The two limiting rollers 8 can limit the plastic bag, allowing the plastic bag to move below the glue coating roller 17. The limiting roller 8 located on one side of the receiving roller 21 can press the laminated plastic bag. A first fixed plate 11 is fixedly connected between two adjacent first vertical plates 9. A first electric rod 12 is installed on the upper surface of the two first fixed plates 11.

[0028] The plastic bag passes under one of the limiting rollers 8 to limit its position. A second electric lever 14 moves the coating roller 17, discharging adhesive from the hopper 13 through the connecting pipe 25 into the outlet 19, where it is discharged and covers the coating roller 17. Another second electric lever 14 moves the coating roller 17 to apply adhesive to the plastic bag. After coating, another layer of plastic bag passes under the pressure roller 31 to cover the coated bag. This layer then passes under another limiting roller 8. During this process, a first electric lever 12 moves the limiting roller 8 to press the plastic bag. Finally, the bag is collected by the receiving roller 21.
