Now, a defecation pad manufacturing method according to an embodiment of the present invention and a defecation pad manufactured thereby will be described in detail with reference to the drawings.

1 is a flowchart illustrating a method for manufacturing a defecation pad according to a first embodiment of the present invention.

1, the defecation pad manufacturing method includes a breathable film manufacturing step (S100), a sheet manufacturing step (S200), and a pad manufacturing step (S300).

In the air permeable film manufacturing step (S100), a plurality of through-holes 101 are formed in the film to prepare the air permeable film 100 . Here, as the film, various types of films such as polyethylene, polypropylene, polyurethane, and polyether may be used.

In one embodiment, the air-permeable film manufacturing step (S100), the film may be continuously passed through a perforator to form a through hole 101 of a fine size over the entire surface of the film.

In one embodiment, the air-permeable film manufacturing step (S100), when forming the plurality of through-holes 101 in the film, may be formed to become narrower from one side of the film to the other side. Accordingly, even if pressure is applied by stepping on the part where the toilet is absorbed by the companion animal, it may serve to prevent the toilet from coming up on one surface of the breathable film 100 again.

In one embodiment, in the air-permeable film manufacturing step (S100), the diameter of the through-hole 101 formed on one side of the film may be larger than the diameter of the through-hole 101 formed on the other side of the film.

In the sheet manufacturing step (S200), the sheet 200 is prepared by mixing the pulp and SAP.

Here, pulp is an aggregate of cellulose fibers obtained by mechanical, chemical or intermediate methods from wood or other fiber plants, and SAP (Superabsorbent Polymer) is a superabsorbent polymer, which is several tens to hundreds of times its own weight. It absorbs water up to the stomach, and since the material itself absorbs water, it absorbs more than cotton or cotton cloth, and does not release water at any pressure.

In one embodiment, in the sheet manufacturing step (S200), the pulp is crushed, and the sheet 200 may be manufactured by sucking the crushed pulp and SAP (Superabsorbent Polymer).

In one embodiment, in the sheet manufacturing step (S200), a fragrance may be added by spraying a predetermined fragrance (eg, natural aroma fragrance, etc.) on the sheet 200, and adding a natural aroma fragrance to the toilet pad In this case, it is possible to keep the indoor air cleaner by suppressing the unpleasant odor generated from the toilet of the companion animal.

In the pad manufacturing step (S300), the breathable film 100 and the sheet 200 are delivered and the waterproof film 300 is delivered at the same time, and the breathable film 100 is attached to one side of the sheet 200 and the sheet 200 ) to prepare a pad by attaching a waterproof film 300 to the other side.

In an embodiment, the waterproof film 300 may be one of a polyurethane film, a polyethylene film, and a polypropylene film.

In one embodiment, the pad manufacturing step (S300), when attaching the breathable film 100 to one side of the sheet 200 and the waterproof film 300 to the other side of the sheet 200, an adhesive between them A method of applying and attaching (eg, hot melt) may be used, and in addition, it may be attached using various methods such as thermal bonding and ultrasonic bonding.

The defecation pad manufacturing method having the steps as described above is shown in the flow chart as if the air permeable film manufacturing step (S100) proceeds before the sheet manufacturing step (S200), but their order may be changed or may proceed simultaneously, and accordingly The manufactured defecation pad is well shown in FIGS.

The defecation pad manufacturing method having the steps as described above, by providing a defecation pad of the breathable film 100, the sheet 200, and the waterproof film 300 triple structure, when the companion animal sees a bowel movement on the defecation pad, The feces flows through the through-hole 101 of the breathable film 100 and is absorbed into the sheet 200, and prevents unabsorbed feces from leaking to the floor by the waterproof film 300, so that a non-woven fabric is not used. Since this excellent defecation pad can be manufactured, product production is easy and manufacturing cost can be reduced.

4 is a flowchart illustrating the sheet manufacturing step in FIG. 1 .

In one embodiment, in the pulp grinding process (S210), natural pulp, which is an eco-friendly material, is supplied and pulverized and delivered to a sheet maker, and a bowel pad made of natural pulp is manufactured so that consumers can use the defecation pad with confidence. can

In the SAP supply process (S220), SAP is supplied by using the SAP supplier.

In one embodiment, the SAP supply process (S220), by supplying the SAP to the sheet maker and allowing not only the toilet containing moisture but also the bacteria that cause the smell to be absorbed by the SAP, it is possible to keep the indoor environment clean.

In the sheet manufacturing process (S230), the sheet 200 is manufactured by adsorbing the crushed pulp and SAP using a sheet maker.

In one embodiment, in the sheet manufacturing process (S230), the sheet 200 may be manufactured by sucking the crushed pulp supplied from the pulp crusher and the SAP supplied from the SAP supply unit.

In one embodiment, the sheet maker may include a rotary roller means, a suction means and a plurality of adsorption means.

The rotary roller means is formed in a cylindrical shape of a preset diameter (for example, 1 meter to 5 meters, etc.), a suction means is formed therein, and an absorption means is formed on a part of the side surface to rotate by receiving commercial power. do.

In an embodiment, the rotary roller means may be formed in a polygonal shape (eg, a triangular prism, a square prism, or a pentagonal prism, etc.) forming a plurality of surfaces for sucking the crushed pulp and SAP.

The suction means is formed inside the rotary roller means, and sucks air into the rotary roller means through the suction means.

In one embodiment, the suction means may suck air through the adsorption means for sucking the pulverized pulp and SAP, and block air suction through the adsorption means that does not adsorb the pulverized pulp and SAP.

The adsorption means is formed in a predetermined shape (eg, a square shape, a triangular shape, or a heart shape, etc.) and a size (eg, 30 cm to 300 cm in width, 30 cm to 300 cm in length, etc.) on a part of the side of the rotating roller means , the crushed pulp supplied from the pulp grinder and the SAP supplied from the SAP supplier in a preset shape (eg, a square shape, a triangular shape, or a heart shape, etc.) and size (eg, 30 cm to 300 cm in width, 30 cm in length to 300 cm, etc.).

5 is a flowchart illustrating a method of manufacturing a defecation pad according to a second embodiment of the present invention.

5, the defecation pad manufacturing method includes a breathable film manufacturing step (S100), a nonwoven fabric attaching step (S400), a sheet manufacturing step (S200), and a pad manufacturing step (S300). Here, the breathable film manufacturing step (S100), the sheet manufacturing step (S200), and the pad manufacturing step (S300) are similar to the method of FIG. 1 , so the description thereof will be omitted and only other parts will be described below.

In the step of attaching the nonwoven fabric ( S400 ), the nonwoven fabric 400 is attached to the edge portion of the breathable film 100 .

In an embodiment, the nonwoven fabric attaching step (S400) may attach the nonwoven fabric 400 to the edge portion of one side of the breathable film 100. At this time, various methods such as adhesion using an adhesive, thermal bonding, ultrasonic bonding, etc. are used. can be attached.

The defecation pad thus manufactured is well shown in FIG. 6 .

The defecation pad manufacturing method having the steps as described above, by forming the nonwoven fabric 400 only on the edge portion of the breathable film 100 rather than the entire surface of the defecation pad, minimize the use of the nonwoven fabric 400 to reduce the cost as much as possible. While doing so, there is an effect that can prevent the feces that do not flow through the through-hole 101 of the breathable film 100 from leaking to the outside.
