Embodiment 2
This embodiment is a further improvement of embodiment 1, and the main improvement lies in that after the user wears the diaper manufactured by the device of embodiment 1, the suspended core is three-dimensional after wearing, and can not fit well with the groin and the inner thigh of the human body, which can cause urine side leakage and uncomfortable wearing experience. In the present embodiment, however, the above-described drawbacks can be effectively avoided.
Specifically, as shown in fig. 1, in the production apparatus for a suspended core diaper according to the present embodiment, a suspended film elastic roll 16 and a suspended film elastic lifting/separating mechanism 17, that is, the suspended film roll 5, the suspended film elastic roll 16, the suspended film elastic lifting/separating mechanism 17, the first glue spraying mechanism 12, and the first pressing roller 7 are provided in this order between the suspended film roll 5 and the first glue spraying mechanism 12. The suspension film elastic ribbon winding wheel 16 is wound with two first elastic ribbons 38, the two first elastic ribbons 38 are separated and stretched to two sides of the suspension film 29 through the suspension film elastic ribbon lifting and separating mechanism 17, the distance between the two first elastic ribbons 38 is equal to the width w of the core 23, and the two first elastic ribbons 38 are adhered to the transition positions where the suspension film 29 is folded with the upper surface and the lower surface of the core 23 while the suspension film 29 is adhered to the upper surface of the core 23. Otherwise, the structure of the device in this embodiment is identical to that in embodiment 1, and a detailed description thereof will be omitted.
As shown in fig. 7, the structure of the suspended core diaper produced by the apparatus in this embodiment is that a first elastic band 38 is added to the folding transition portions between the two sides of the suspended film 29 and the upper surface and the lower surface of the core 23, respectively, that is, the interval between the two first elastic bands 38 is equal to the width w of the core 23. The arrangement of the first rubber band 38 enables the suspending core paper diaper to be attached to the inner sides of groins and thighs of a human body after the suspending core paper diaper is worn, so that side leakage is effectively prevented, and a user wears the suspending core paper diaper more comfortably. In addition, the structure of the suspended core diaper produced by the apparatus in this embodiment is identical to that of the diaper in embodiment 1, and details thereof will not be described here.
Embodiment 3
This embodiment is a further improvement of embodiment 2, and is mainly improved in that in embodiment 2, when the core 23 covered with the suspension film 29 is to be conveyed from the first forward suction cup conveyor 1 to between the reverse suction cup conveyor 2 and the lower folding mechanism 9, since both sides of the suspension film 29 are kept taut, it is easy to cause that the suspension film 29 having the first preset width w1 on both sides is not smoothly pressed and folded by the two pressing bars 32 in the folding mechanism 9 to the lower surface of the core 23, which may cause the occurrence of defective products. In the present embodiment, however, the above-described drawbacks can be effectively avoided.
Specifically, in this embodiment, as shown in fig. 1 and 8, two arc-shaped limiting rods 28 are further vertically fixed between the first forward sucking disc conveying belt 1 and the reverse sucking disc conveying belt 2 through a bracket 39, the cambered surfaces of the two limiting rods 28 are oppositely arranged, the distance between the cambered surfaces of the two limiting rods is smaller than the width of the suspension film 29, and both sides of the suspension film 29 can be slightly pressed down by the cambered surfaces of the two limiting rods. In this way, before the suspension film 29 and the core 23 enter between the reverse suction cup conveyor belt 2 and the folding mechanism 9, the edges of the suspension film 29 with the first preset widths w1 on both sides can be pressed down by the cambered surfaces of the cambered limiting rods 28 on both sides, so that the edges of the suspension film 29 with the first preset widths w1 on both sides can be smoothly folded to the lower surface of the core 23 under the cooperation of the two pressing rods 32 and the positioning wheels 31.
Otherwise, this embodiment is identical to embodiment 2, and a detailed description thereof will be omitted.
The foregoing embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
