[0025] After the large-sized three-layer paper is separated into the first layer of paper, the second layer of paper, and the third layer of paper arranged from top to bottom by the paper separating mechanism, it enters the horizontal gluing mechanism of the present utility model for gluing. The first layer of paper is glued at the first coating unit 1, the second layer of paper is glued at the second coating unit 2, and the third layer of paper is glued at the third coating unit 3.

The glue applicator roller 6 is located between the adhesive roller 4 and the paper tensioning roller 7, and a rhythmical dispensing mechanism 9 is installed on the glue applicator roller 6. When the adhesive roller 4 rotates, it drives glue from a glue trough (not shown in the figure) to adhere to its surface. When the glue applicator roller 6 rotates, the rhythmical dispensing mechanism 9 contacts the adhesive roller 4 to adhere the glue, and then applies the glue to the paper 8 tensioned on the paper tensioning roller 7 during operation.

[0027] In one or more specific embodiments of the present utility model, the rhythmical dispensing mechanism 9 includes two sets of rings 11. The two sets of rings 11 are installed on the glue applicator roller 6, and a mounting plate 12 is installed between the two sets of rings 11. A number of rows of dispensing heads 10 are installed on the mounting plate 12.

[0030] In one or more specific embodiments of the present utility model, each coating unit further includes an auxiliary glue applicator roller 5. The outer surface of the auxiliary glue applicator roller 5 is attached to the outer surface of the adhesive roller 4. The glue applicator roller 6 is located between the auxiliary glue applicator roller 5 and the paper tensioning roller 7. At this time, when the adhesive roller 4 rotates, it drives glue from a glue trough (not shown in the figure) to adhere to its surface. When the auxiliary glue applicator roller 5 rotates, it adheres the glue. The auxiliary glue applicator roller 5 and the adhesive roller 4 form a glue space for accommodating the glue. When the glue applicator roller 6 rotates, the rhythmical dispensing mechanism 9 contacts the auxiliary glue applicator roller 5 to adhere the glue, and then applies the glue to the paper 8 tensioned on the paper tensioning roller 7 during operation. The setting of the auxiliary glue applicator roller 5 makes the glue adhered on each dispensing head 10 more uniform, so that the glue applied to each dispensing point on the paper 8 is more uniform.

[0031] In one or more specific embodiments of the present utility model, the two sets of rings 11 are detachably installed on the glue applicator roller 6. The ring 11 can be a clamp or other detachable fasteners.

[0032] Those skilled in the art should be aware that in the present utility model, the adhesive roller 4, the glue coating roller 6, the auxiliary dispensing roller 5, and the paper tensioning roller 7 can all be rotated by a motor or by other driving means, as long as the adhesive roller 4 can rotate to adhere from the glue coating roller, the auxiliary dispensing roller 5 can rotate to adhere the glue coming from the adhesive roller 4, and the glue coating roller 6 can rotate to coat the glue onto the paper. The present utility model does not make special limitations on the driving providing method.
