Next, the pressing mechanism 400 in the roll supporting and pressing device disclosed in this embodiment will be explained in detail:

Referring to fig. 2 and 3, the pressing mechanism 400 has a pair of pressing rollers including a driving pressing roller 410 and a driven pressing roller 420 arranged in a vertical direction, and a pressing gap extending in a horizontal direction is provided between the driving pressing roller 410 and the driven pressing roller 420. It should be noted that the lamination gap extends in the horizontal direction because the single sheet 122 and the sheet 310 to be laminated are conveyed in the horizontal direction, and thus this design can ensure that the adhesive lamination is performed. And, the driving nip roller 410 and the driven nip roller 420 are also provided with nip mating rollers 470 at both sides.

The driving nip roller 410 is located below the driven nip roller 420, and a driving unit is disposed at the outer side of one axial end of the driving nip roller 410. Wherein the driving unit includes a press-fit driving motor 430 fixedly provided on the frame 100 in driving connection with the corresponding one side shaft end of the driving press-fit roller 410.

And the side of the single sheet 122 coated with the adhesive faces upward while passing through the synchronous conveying roller 600, and the sheet 310 to be laminated is located above the single sheet 122. This design ensures that the adhesive is not contaminated or damaged during the transport and lamination process, while also facilitating adequate contact and adhesion of the adhesive to the sheet 310 to be laminated.
