when the laminating device is used for laminating, a plurality of laminating supports (60) are arranged on the output end of the laminating conveying structure (12) from the front to the back side of the baffle bar (61); at the moment, the laminated material stopping top plate (59) acts to prohibit the laminated bracket (60) from passing through; the output end push plate (63) and the input end push plate (64) are respectively pressed on the left side and the right side of the laminated support (60), the material receiving toothed plate (66) extends to the position right above the laminated support (60), and the strip-shaped teeth are positioned right above the laminated circular bosses (68) of the corresponding laminated support (60) and are inserted into a space surrounded by 4 laminated limiting rods (69); the transfer manipulator (11) transfers a plurality of compressed towels (17) on the output end of the waiting platform (10) to the strip-shaped teeth corresponding to the material receiving toothed plate (66), and the multiple transfers realize lamination; after lamination is completed, the material receiving toothed plate (66) shrinks, the compressed towel (17) falls onto the laminated support (60), and the output end push plate (63) and the input end push plate (64) are matched to push the laminated support (60) laminated with the compressed towel (17) to the input end of the laminated conveying structure (12).

9. The automatic packaging system of the compressed towel, as recited in claim 1, characterized in that the alignment device comprises a front film-covering material-stopping top plate (70), an alignment die (72) and a rear film-covering material-stopping top plate (73) which are sequentially arranged on the laminated conveying structure (12) from front to back, the alignment die (72) is positioned right below the laminated film-covering device (13) and is composed of two alignment half dies which are arranged on the left and right sides of the laminated conveying structure (12) and can move relatively, and the inner sides of the alignment half dies are vertically provided with an arc groove matched with the compressed towel (17) and a strip groove matched with the laminated limiting rod (69);

the rear film-covering material stopping top plate (73) is driven by a corresponding air cylinder to move left and right, when the rear film-covering material stopping top plate (73) extends, the rear side of one laminated bracket (60) is abutted against the rear film-covering material stopping top plate (73) and is positioned right below the laminated heat shrinking device (14) for alignment and film covering, and when the laminated bracket (60) passes through when the laminated heat shrinking device shrinks;

the front film stopping material top plate (70) is driven by a corresponding air cylinder to move left and right to stop or pass through the laminated support (60);

the aligning half-moulds are driven by corresponding air cylinders to move left and right, when the aligning half-moulds extend, a plurality of compression towels (17) on the laminated support (60) are aligned up and down, and when the aligning half-moulds contract, the laminated support (60) passes through.

10. The automatic packaging system for the compressed towel according to claim 1, characterized in that a circular pressing plate (79) and a packaging film pressing plate (77) which can move vertically are sequentially arranged between the top label output device (7) and the packaging heat shrinking device (8) from front to back, and the circular pressing plate (79) and the packaging film pressing plate (77) are both positioned right above the packaging conveying structure (4); a lamination film pressing plate capable of moving vertically is arranged between the lamination film covering device (13) and the lamination heat shrinking device (14), and the lamination film pressing plate is positioned right above the lamination conveying structure (12); the packaging film pressing plate (77) and the laminated film pressing plate are arranged in the front-back direction, and the front end of the laminated film pressing plate is tilted upwards.
