[0034] In order to further realize the front and rear conveying function of the tissue paper shell adhesive body, in some optional embodiments, the first front and rear feeding roller module 44, the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 are all connected to the front and rear feeding drive module 43 through a roller synchronous belt, and the first front and rear feeding roller module 44, the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 all include relatively arranged feeding active roller 461 and feeding driven roller 462, and a first skin shell tissue paper activity area is formed between the feeding active roller 461 and the feeding driven roller 462; wherein, the front and rear feeding drive module 43 drives the first front and rear feeding roller module 44, the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 to roll through the roller synchronous belt, thereby driving the tissue paper and the paper shell to move back and forth in the first skin shell tissue paper activity area.

[0035] It should be noted that the front and rear feeding drive modules 43 use a driving motor as a power source. The driving motor drives the feeding active roller 461 and the feeding driven roller 462 to roll through the roller synchronous belt. The feeding active roller 461 and the feeding driven roller 462 drive the facial paper and paper shell to move from the first skin shell facial paper active area with high precision.

[0036] In order to further implement the front and rear edge folding functions of the facial tissue and case bonding body, in some alternative embodiments, the front edge folding module 47 and the rear edge folding module 48 include a front and rear edge folding driving device 471, a front and rear edge folding transmission device 472, and a front and rear edge folding device 473. The front and rear edge folding driving device 471 is fixed on the front and rear edge folding fixing bracket 41. The front and rear edge folding device 473 includes a folding fixing shaft 4731, a folding swing block 4732, a folding fixing bolt 4733, and a folding insertion plate 4734. The folding fixing shaft 4731 is in transmission connection with the folding driving device through the front and rear edge folding transmission device 472. The folding swing block 4732 is provided with an elongated adjustment hole. The folding swing block 4732 is swingably arranged on the folding fixing shaft 4731 through the elongated adjustment hole and the fixing bolt. The folding insertion plate 4734 is arranged on the folding swing block 4732. A facial tissue folding angle 4735 is formed between the folding swing block 4732 and the folding insertion plate 4734. The opening of the facial tissue folding angle 4735 formed between the folding swing block 4732 and the folding insertion plate 4734 of the front edge folding module 47 faces forward, and the opening of the facial tissue folding angle 4735 formed between the folding swing block 4732 and the folding insertion plate 4734 of the rear edge folding module 48 faces backward. Among them, the front and rear edge folding driving device 471 drives the front and rear edge folding device 473 to perform up and down lifting movements through the front and rear edge folding transmission device 472. The facial tissue abuts against the folding swing block 4732 and the folding insertion plate 4734 and swings on the folding fixing shaft 4731 along the elongated adjustment hole with the folding fixing bolt 4733 as the base point, so as to wrap the front and rear sides of the facial tissue around the case through the facial tissue folding angle 4735.

[0037] It should be noted that the front and rear edge folding driving device 471 can drive the front and rear edge folding transmission device 472 to work. Specifically, the front and rear edge folding driving device 471 is a driving cylinder, and the front and rear edge folding transmission device 472 is a crank structure.

The folding swing block 4732 and the folding insertion plate 4734 of the front and rear edge folding device 473 swing on the folding fixing shaft 4731 along the aperture direction of the elongated adjustment hole with the folding fixing bolt 4733 as the base point.

[0038] Further, after the face paper and shell adhesive body is pressed by the auxiliary feeding module 42 and enters the first front and rear feeding roller module 44, the front and rear folding device 473 of the rear side folding module 48 is lifted and avoided by the front and rear folding transmission device 472, so that when the first front and rear feeding roller module 44 and the second front and rear feeding roller module 45 can normally drive the face paper and shell adhesive body to move forward without being blocked. When the front side of the face paper enters the face paper folding angle 4735 of the front side folding module 47, as the forward thrust of the first front and rear feeding roller module 44 and the second front and rear feeding roller module 45 increases, the folding swing block 4732 and the folding insertion plate 4734 of the front side folding module 47 swing on the folding fixed shaft 4731, forcing the front side of the face paper to deform and bend, so that the front side of the face paper adheres to the front side of the shell to complete the front side edge wrapping process; after the front side edge wrapping process is completed, the front and rear folding device 473 of the front side folding module 47 is lifted and avoided by the front and rear folding transmission device 472, so that when the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 can normally drive the face paper and shell adhesive body to move backward without being blocked. When the rear side of the face paper enters the face paper folding angle 4735 of the rear side folding module 48, as the backward thrust of the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 increases, the folding swing block 4732 and the folding insertion plate 4734 of the rear side folding module 48 swing on the folding fixed shaft 4731, forcing the rear side of the face paper to deform and bend, so that the rear side of the face paper adheres to the rear side of the shell to complete the rear side edge wrapping process; after both the front side edge wrapping and the rear side edge wrapping are completed, the first front and rear feeding roller module 44, the second front and rear feeding roller module 45 and the third front and rear feeding roller module 46 jointly drive the edge wrapped semi-finished product to the left and right edge wrapping mechanism 500, with smooth operation, and can automatically complete the front and rear edge wrapping processes with high precision.
