Description

1284524 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a molding method, and more particularly to a molding method for producing a thin layer and a mold thereof. [Prior Art] Hygiene products used in daily life, especially those that are in direct contact with the body's skin, such as diapers and sanitary napkins, must have the characteristics of quickly absorbing liquid and preventing wintering, in order to provide users with a feeling of dryness and comfort. Referring to Figure 1, a perforated film 2, which is commonly used in the aforementioned sanitary articles, has a base layer 21. Referring to FIG. 2, the base layer 21 defines a hydrophobic first surface 211 and an opposite second surface 212, and includes a plurality of through holes 213 extending from the first surface 211 to the second surface 212. In the actual use state, the perforated film 2 is attached to the second surface 212 side with an absorber (not shown), so that the liquid permeates through the perforations 213 to the side of the second surface 212 and is absorbed by the absorber. All the holes 213 疋 are applied with a positive pressure from the first surface 211 , or a negative pressure is applied to the second surface 212 to cause the base layer 21 to be penetrated. Therefore, the aperture of the through hole 23 adjacent to the first surface 211 is larger than the adjacent second surface 212 . If the pore diameter is used to absorb a liquid having a large cohesive force, the surface tension is relatively high, and a liquid having a high viscosity is likely to accumulate at the position of the first surface 211 between the perforations 213, so that the porous membrane 2 cannot be sufficiently utilized. The effect of the flow. In addition, in order to ensure the structural integrity of the porous membrane 2, the distance between the two perforations 213 must be a certain distance, so that the surface area of the base layer 2 is not formed to be too large, so that the porous membrane 2 is in contact with the skin for a long time, which is quite easy to cause friction or Uncomfortable tactile sensation, especially when the liquid that is not removed along the perforation 5 1284524 213 remains on the first side of the crucible, it will cause sultry and allergic phenomena, forming a hygienic, L-reverse, even if some operators try to use the expansion perforation 213 The hand of the aperture:: to increase the liquid removal effect and reduce the area in contact with the skin, but the menstrual period causes the porous membrane 2 to derive a problem of rewet. σ, on the one hand, is also because the surface area between the perforations 213 is too large, meaning that the part of the porous membrane 2 having the wear &

Mould: The contact area with a high ratio makes the porous membrane 2 removed from the mold: Poor: Guangcheng Duo (4) 2 is easy to stick to the mold, and if the external force is strong, a '2 is released' may even make the porous membrane 2 Local rupture = Touch ^ How to create an H with optimal liquid removal efficiency and reduced skin contact surface area while maintaining structural strength is a technical field to be overcome. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a method of producing a surface pressure that can destroy a liquid to produce &贤力Μ produces the thin layer of the car

Therefore, the forming method of the thin layer of the present invention firstly causes a base layer to be attached to the continuous mold heating, wherein the base layer is softened by heat and adheres to the mold. The pure mold includes a plurality of first types which are adjacently arranged and surrounded by a specific shape. And stacked on the first molding portion_ side and arranged in a mesh shape: a portion. A portion of the base layer is in contact with the other side of the first forming portion and has a rib shape. Then, the base layer is evacuated, and the ribbed ring is surrounded by the inner force layer and the second molding portion is pressed to correspond to the second molding (4): the region is broken into a hydrophobic hole. Finally, the base layer is separated from the mold to obtain a thin = Zhengong J284524. Another object of the present invention is to provide a mold capable of forming a base layer into a thin layer having tensile strength, which has a plurality of first molding portions and: two molding unit. Among them, all of the first molding portions are arranged adjacent to each other in a specific form, and the second molding portions are connected in a mesh shape and are not coplanarly stacked on one side of the first molding portion. [Complex method] The foregoing and other technical contents, features and effects of the present invention are

The detailed description of the preferred embodiment with reference to the drawings will be apparent. Referring to Figure 3, the method for forming the thin layer of the present invention is to process a base layer 3 through multiple processes ' and the base | 3 may be a high molecular polymer or a material such as a woven fabric. A larger non-woven fabric is taken as an example for explanation. The processing equipment of the lance and the forming step are respectively as follows: a conveying unit W defining a winding path and a closing path, a rotary mold 42 disposed on the conveying path of the conveying unit 41, and inputting one of the conveying paths A heating unit 45 between the ends 43 44, a pumping valve for the air pumping step 46, and a water needle step downstream of the drawing unit 46 on the conveying path, 4+歩W η. 61. A drying unit 62 located downstream of the water pair CS 61 and a separation assist unit 63 at a 42° separation point. /, the mouth conveying unit 41 is driven by a plurality of rollers 411, and the base layer 3 is driven to pass through the heating unit and the silverware 42-seat extraction unit 46 on the conveying path. Finally, the base layer 3 is separated from the mold 42 to obtain a thin layer. Referring to Figures 4 and 5, the mold 42 is wound. The end point continuously rotates the mold, which is made of metal, ceramic or "axial" material. 7 J284524. The chandelier 42 includes a plurality of first forming portions 42i, and a second molding portion 422 stacked on one side of the forming surface 421. All of the first forming portions 421 are adjacently arranged to form a perforated plate 47, and the first forming portion 421 is wound into a special shape: ^ 4 4 The setting pattern can be any geometric figure #, such as a diamond shape (Benbesch) The examples are disclosed) or elliptical. Similarly, all of the second molding portions 仏 are also arranged in a mesh-like porous & 48, each of which has a smaller pore diameter than the inner diameter of the wound shape of the first molding portion 421, and a perforated plate formed with the first molding portion 421.

47 is not coplanar. The mold 42 may also be composed of a transfer belt having first and second molding portions 421 and 422. • The 4-lead unit 46 is disposed integrally with the mold 42 but does not rotate synchronously with the mold 42. The base portion has a first molding portion 42 ι overlapping the same side of the second molding portion 仏 2, and has a molding and molding. An air suction port 461 in which the partial air-vacuum regions of the portions 42 i and 422 communicate with each other, and an air extractor 462 that performs air suction from the air suction port 461. The stacking order of the base layer 3, the first molding portion 421, and the second molding portion 422 can be defined, and the direction of the drawing machine 462 is the pumping direction. The operation of the drawing machine 462 can cause the mold 42 to be relatively adjacent to the drawing unit. The side pressure is low and it is a negative pressure environment. The X-hand needle government 61 is disposed on the side opposite to the second molding portion 422, and emits a high-pressure water column containing the abrasive particles in the same direction, which is a conventional hole or cut 1j in years jrc v. 11 - 7- t? Yu slave, Fang; this is not repeated. The drying unit 62 is the same as 1 c)], and the cooling airflow flowing in the direction of pumping is extracted. The separation assisting unit 63, the rabbit n f- ^ ^ ^ 0 is a fan, whose air flow direction is opposite to the direction in which the high-pressure water column and the cold portion air flow are carried. Referring back to FIG. 3, the base layer 3 is fed from the wheel-in terminal 43 so that the base layer 3 is attached to the first forming portion 421 of the 8 1284524 opposite to the first _, and when the twisting unit 45 is passed, the portion 422 is surrounded by the lateral hot air. The local high temperature environment 45 sends the ribs 51 toward the base layer 3 (the protruding direction of the ribs 51 is 21 corresponding to the base layer 3 along with the mold 42 =, the two molding portions 422) ° to the (4) unit 46, _^4 Rotating forward on the 6th feed path, and creating a partial outline in the vicinity of the straight line: the part 2 of the near-two forming part 422 is surrounded by the rib 51 of the soil layer 3 under the pulling force to define m toward the second forming part 422 The tensile deformation of the two-part base layer 3 abuts against the hollowed-out region of the second forming portion 422. The second base is ruptured into a hydrophobic hole 52 ^ - the partial base layer 3 receives an attractive force, and the thickness of the knitted fabric is larger. It must be impacted by the water needle device 6" with the water hole:: the entire hydrophobic hole 52, to ensure that the degree is sufficient for the liquid to flow. The water droplets of the base layer must be thoroughly modified by the boring wheel to be blown by the drying unit 62 of the turret, so that the base layer 3 becomes dry. This step is also advantageous for the subsequent demolding action.

The C-axis is rolled away from the take-off path and becomes wrapable. As noted here, in order to avoid the product being stuck to t-. On the illusion 4 occurs, the separation of the auxiliary shore is set by the separation point of the finished product, which is in the direction of anti-pumping, which is equivalent to the side of the second squad 422 to the gentleman / L soil. The airflow is blown in the direction to assist in the removal of the finished product. 4 to 6 are the finished views of the thin layer 5, and the base layer 3 attached to the first portion J284524 portion 421 becomes a rib 5, and the rib 51 shown in the figure is a diamond shape, which is only formed according to the first molding. The other various geometrical structures formed by the portion 421, such as the honeycomb shape, the elliptical shape, and the triangular shape, are all within the flexible range, and even the non-slip-like rib 53 of FIG. 7 and the polygonal petal-like continuous rib shown in FIG. The honeycomb hydrophobic hole 52' is fitted to the crucible, and is not limited to this embodiment.

The present invention utilizes a portion of the base layer 3 after softening to contact the first molding portion 421 to form the rib 51. In practical use, the thin layer 5 is directly contacted by the user with the rib 51, instead of the thin layer 5. The total contact area of the side surface completely attached to the user's skin is limited to the rib 51, which greatly reduces the contact surface area between the thin layer 5 and the user, which is different from the distance between the two perforations 213 of the conventional perforated film 2 The problem is that the contact area with the user is too large to solve the problem of sultry heat and discomfort. Furthermore, 'because the thin layer 5 and the user only contact the rib 5', the liquid retention rate dropped on the thin (four) 5 is reduced, and most of the liquid is quickly discharged from the rib gap 'by the hydrophobic hole 52, which is not easy. Remaining in the thin: layer 5 'and the rib 5 1 also has the effect of breaking the surface tension of the liquid' can improve the problem that the liquid has low discharge due to excessive cohesion. From the structural point of view, 'especially in the thin layer 5, the thin layer 5 is subjected to a large tensile tension, and the shank of the temple 4 is connected to the rib 51 for the mechanical strength to resist the tensile force. Cooperating with the separation assisting unit 63 to blow the gas >, rL, lowering the finished product and the fourth (4) lifting, will cause the mold to be detached from the mold, and conversely, the distance between the perforated film 2 and the door of the perforated 213 is too long. The tension between the pomelo chess player I r 1 · 3 ... stretched the tension between the (four) 'easily easily plagued by two perforations 213 曰 directly (four), causing the perforated membrane 2 to be unusable. 10 1284524 值 思 疋 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , And not coplanar, it means that the mold 42 can exhibit various combinations, and the different porous plates cooperate with each other to produce a plurality of variations of the arrangement of the ribs 51 and the hydrophobic holes 52. The present invention further utilizes the water needle device 61 to provide a high pressure water column: when used for the base layer 3 having a relatively thick thickness, the hydrophobic hole 52 can be prevented from being broken due to insufficient suction force.

The problem of extraordinary, ensuring that each of the hydrophobic holes 52 can properly perform the function of removing the liquid, and if the present invention is applied to other base layers having a lower thickness, and the rupture of the hydrophobic holes 52 is easy to grasp, the water needle is loaded. 61 can be selected for temporary use. In summary, the molding method for manufacturing the thin layer 5 of the present invention and the mold 42 thereof are formed on the base layer 3 through the first molding portion 421 to form a rib 5, which greatly reduces the contact with the user. In addition, the liquid can be quickly and efficiently removed from the hydrophobic hole 52. The mold 42' composed of the first and second molding portions 42|, 422 is matched to make the thin layer material of the unevenness and the like a mechanical strength sufficient to resist stretching.
