In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or practice. Therefore, the definition of these terms should be described based on the contents throughout this specification.

In addition, the described embodiments are provided for illustrative purposes only, and do not limit the technical scope of the present invention.

Hereinafter, an apparatus for manufacturing an absorber for diapers according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Structure of forming drum

This will be described with reference to FIGS. 1 to 3. The forming drum 100 used in the apparatus for manufacturing an absorber for diapers according to the present invention includes a main body 110 and a slit forming plate 130.

The main body 110 is formed in a cylindrical shape (roller), and is formed to rotate in one direction about the rotation shaft 112, and for this purpose, is connected to a power means (not shown). At this time, the outer circumferential surface of the main body 110 may be formed in a concave structure along the rotational direction of the main body 110, a plurality of slit forming plates 130 to be described later may be mounted on the concave structure, and the slit It is preferable that the forming plate 130 is tightly mounted along the outer circumferential surface of the main body 110 to enclose all the outer circumferential surfaces of the main body 110.

The slit forming plate 130 is formed to be mounted on the outer circumferential surface of the main body 110, and the slit forming plate 130 is installed so that the outer circumferential surface of the main body 110 and the bottom surface of the slit forming plate 130 are closely mounted to facilitate rotation. The curvature of is preferably formed to be the same as the curvature of the main body 110.

The slit forming plate 130 is composed of an outer shape forming portion 132 and a slit forming portion 134.

The outer shape forming portion 132 is a shape indented in a predetermined shape toward the inner side which is the direction of the rotation shaft 112. Accordingly, when the main body 110 rotates, the absorber is formed on the outer surface of the slit forming plate 130 by pressing the pulp (pulverized pulp) and absorbent material constituting the absorber.

The slit forming portion 134 is disposed in a direction extending along the rotational direction of the forming drum 100 in the outer forming portion 132, and is formed in a bar shape protruding on the outer forming portion 132. As described above, as the slit forming portion 134 is formed in a protruding structure, the slit channel indented in the protruding direction of the slit forming portion 134 may be formed by being pressed against the absorber by facing it. As the fluid, which is the wearer's urine fluid, can flow through the slit channel, the fluid does not stay in one site and exerts an effect that can be absorbed more quickly by the absorber in the process of flowing further through the slit channel.

If it is not absorbed quickly, there may be a problem that may cause a rash in a child with weaker skin than an adult, or a skin disease and an obstetrics disease in the perineum of a woman in which cleanliness is important. For women's sanitary napkins, fast absorption is of utmost importance.

As described above, the present invention can form a slit channel that is a flow path through which a fluid can flow through a bar-shaped slit forming part 134 extending in one direction, and the thickness, height, and shape of the slit forming part 134. The back may be designed considering the wearer's gender and age. Specifically, the shape of the slit forming portion 134 is also not limited, but has both ends that extend from the parallelly facing intermediate portions of each channel, and each of the two ends are separated from each other (see FIG. 5A ), and both ends are Wider than the middle portion (see b in Fig. 5), each end portion is a shape that is split from the middle portion and can be configured by different angles (see c and d in Fig. 5), and thus formed on the absorber The slit channel 110 may be formed in various shapes.

On the other hand, referring to Figure 4 again, unlike the outer circumferential surface of the forming drum 100, it may be made of a structure having a round indentation groove is formed. This may have a different body structure (meaning length and width) depending on the age of the wearer. For example, the structure of FIG. 4 may be used for an adult diaper or the like.

In addition, a bar-shaped slit forming portion 134 is provided in a pair, and is spaced apart by a predetermined distance to be uniformly absorbed throughout the absorber, and both ends of the slit forming portion 134 are outside It is bent by a predetermined angle toward the bar, through which the wearer's urination fluid does not stay in the center of the absorber, but is absorbed uniformly toward the outside of the absorber, thereby preventing the urination fluid from leaking out of the diaper.

On the other hand, the height of the slit forming portion 134 is smaller than the depth at which the outer forming portion 132 is indented, and it is preferable that the outer forming portion 132 is formed at 80 to 95% of the indented depth. If it is less than 80%, the amount of urination fluid flowing through the slit channel is too small, and if it is more than 95%, the depth of the slit channel becomes too large, which may cause a problem that the urination solution remains in the slit channel. , Because this also prevents uniform absorption into the entire absorber. At this time, it is preferable that the slit forming portion 134 has a lower step than the edge of the slit forming plate 130 (meaning an indented portion) to prevent collision when the forming drum 10 rotates.

In addition, the slit forming portion 134 may be positioned to be detachable on the outer forming portion 132, for example, by forming a fitting groove (not shown) in the outer forming portion 132 to fit the fitting groove/ It may be configured to be detachable or detachable by forming an engaging portion (not shown) in the outer forming portion 132 to engage/separate the engaging groove, but is not limited thereto.

Referring to FIG. 6, when the diaper in which the absorbent body 20 is located is worn by the user (mainly young, infant) by the slit channel 24 in which the central portion 21 and the peripheral portion 22 of the absorbent body 20 are positioned therebetween. By allowing the perineal portion 1 to flexibly adhere along the curve, it is possible to prevent the discharged thixoside from leaking out of the diaper. In addition, the edge portion 26 is formed of a non-woven fabric, as described below, the center portion 21 and the peripheral portion 22 may be sealed by a non-woven fabric using a hot melt adhesive.

On the other hand, referring back to Figure 3, the slit forming plate 130 according to the present invention, the outer forming portion 132 is provided with a mesh network, the pulverized pulp and polymer absorbent mixed by the vacuum chamber 101 to form the outer shape It is formed to be adsorbed on the outer surface of the portion (132).

To this end, referring to b of FIG. 3, a mesh network is also provided on the bottom surface of the slit forming plate 130. At this time, in order to smoothly apply the vacuum, the size of the mesh network grid of the outer shape forming unit 132 is preferably smaller than the size of the mesh grid of the slit forming plate 130.
