The selection of hot pressing point position has its mesh, and the hot pressing point on the first rubber band is close to the intersection department of first rubber band and second rubber band, can be so that the first rubber band keep a trapezoidal state in main shape, perhaps be a sunken state, can realize from the tractive between waistline portion to crotch portion like this, the hot pressing point of second rubber band is close to the intersection department of second rubber band and third rubber band, can guarantee like this that the formation of this position department is an effective tractive to crotch portion middle part, and first rubber band cooperation second rubber band just can realize the effective support to the anter position. Similarly, the third rubber band and the fourth rubber band are basically similar to the first rubber band and the second rubber band.
4. The first rubber band, the second rubber band, the third rubber band and the fourth rubber band form wave-shaped curves on continuous base materials, the vertical distance between the wave crest and the wave trough of the first rubber band is larger than the vertical distance between the wave crest and the wave trough of the second rubber band, the first rubber band and the third rubber band are enabled to form a main lifting support effect, the second rubber band and the fourth rubber band mainly play a role in preventing the bottom center from forming obvious falling in practical application, and more of the first rubber band, the second rubber band, the third rubber band and the fourth rubber band are also a transverse drawing effect. Certainly, the cooperation of first rubber band, second rubber band, the cooperation of third rubber band, fourth rubber band also can play crucial connection effect for the effect of this kind of tractive bearing obtains effectual continuation.
5. The third rubber band and the first rubber band are symmetrically arranged along the crotch, and the fourth rubber band and the second rubber band are symmetrically arranged along the crotch. In practical infant pull-up pant applications, the actual asymmetry tends to shift a small distance towards the front panel portion, which requires more pulling force, since the front panel portion is the portion that primarily receives urine. And adult pull-up diaper is because adopted four rubber bands, and its absorption rate, diffusion rate are all very fast moreover, and pulling force is not the problem, as long as diffusion rate satisfies the demand can, the distribution of pulling force can also be realized better to the mode of equipartition for the effect of bearing is better. It is also more even for the profile.
6. Because the unreeling is different from the unreeling of the two existing rubber bands, the structure of the unreeling device needs to be correspondingly improved. In this scheme, adopted first S-shaped to apply mechanism, second S-shaped to apply the mechanism, utilized first S-shaped to apply mechanism input first rubber band, second rubber band on the substrate material, utilized second S-shaped to apply mechanism input third rubber band, fourth rubber band on the substrate material for first rubber band, second rubber band, third rubber band, fourth rubber band form wavy curve. Specifically, the guide control of the first rubber band and the second rubber band is realized through an auxiliary servo motor and an auxiliary rotating rod, and the rubber band is moved in a large direction by utilizing a main servo motor and a main rotating rod. In addition, due to the problem of pulling force, the main rotating rod is configured, so that balance can be effectively realized, better rubber band application is realized, and longer service life is obtained. In addition, the ratio of the angular velocity of the rotation of the auxiliary rotating rod to the angular velocity of the rotation of the main rotating rod is 1: (1.5 ~ 3), its numerical value can set up according to actual need, usually speaking should not too big nor too little of the ratio of rotation angular velocity, can not reach better control when too big can lead to the elastic ribbon to apply, and the undersize can lead to the deformation of elastic ribbon.

Referring again to fig. 6, there is provided an adult pull-up pant based on the same inventive concept, which differs from the product shown in fig. 1 in that: the wavy bent portion 311 is formed between the hot pressing points in the core body range on the first rubber band, and is formed by swinging and oscillating the auxiliary rotating rod at the position, namely when the main rotating rod is basically fixed, the auxiliary rotating rod swings at a small angle, so that the first rubber band can be arranged in a wavy manner, the aim is to weaken the elastic tension of the rubber band at the position, the absorption of wrinkles and distortion of the core body is more effectively prevented, and the flatness of the product form is kept. Similarly, the second rubber band, the third rubber band and the fourth rubber band can be molded in the mode to form the same wavy bending part.
By adopting the technical scheme, the invention has the beneficial effects that:
1. this scheme is through the setting of first rubber band, second rubber band, third rubber band, fourth rubber band, solves current adult pull-up diaper bearing power not enough and the technical problem of tenesmus. Also solves the problem that the process is difficult to realize when the rubber band is compounded. It has effectively solved the tenesmic problem through four mutual collocation of rubber band, provides a better bearing structure. The adult pull-up pants cannot fall down, but can be supported to a certain extent when falling down, so that the wearing comfort is realized, and only compared with the existing adult pull-up pants, the falling-down degree of the adult pull-up pants is reduced, and the comfort is improved.
2. A plurality of hot pressing points are arranged, and the rubber band is compounded in a viscose mode generally, but the glue has irritating taste and is not environment-friendly. Can be as few as possible use glue, be a better mode to panty-shape diapers product itself, but the glueing is few just causes easily to come unstuck, or causes the product to cause the distortion outward appearance under the uneven condition of rubber band bonding, or just reduces the efficiency of bearing. The mode that hot pressing point combines the glueing has been adopted in this scheme, and it can realize the complex of rubber band better, can realize the purpose of bearing better, has also reduced the use of glue.
3. The selection of hot pressing point position has its mesh, and the hot pressing point on the first rubber band is close to the intersection department of first rubber band and second rubber band, can be so that the first rubber band keep a trapezoidal state in main shape, perhaps be a sunken state, can realize from the tractive between waistline portion to crotch portion like this, the hot pressing point of second rubber band is close to the intersection department of second rubber band and third rubber band, can guarantee like this that the formation of this position department is an effective tractive to crotch portion middle part, and first rubber band cooperation second rubber band just can realize the effective support to the anter position. Similarly, the third rubber band and the fourth rubber band are basically similar to the first rubber band and the second rubber band.
4. The first rubber band, the second rubber band, the third rubber band and the fourth rubber band form wave-shaped curves on continuous base materials, the vertical distance between the wave crest and the wave trough of the first rubber band is larger than the vertical distance between the wave crest and the wave trough of the second rubber band, the purpose of the arrangement is to enable the first rubber band and the third rubber band to form a main lifting supporting effect, the second rubber band and the fourth rubber band mainly play a role in preventing the bottom center from forming obvious falling in practical application, and more is a horizontal drawing effect. Certainly, the cooperation of first rubber band, second rubber band, the cooperation of third rubber band, fourth rubber band also can play crucial connection effect for the effect of this kind of tractive bearing obtains effectual continuation.
5. The third rubber band and the first rubber band are symmetrically arranged along the crotch, and the fourth rubber band and the second rubber band are symmetrically arranged along the crotch. In practical infant pull-up pant applications, the actual asymmetry tends to shift a small distance towards the front panel portion, which requires more pulling force, since the front panel portion is the portion that primarily receives urine. And adult pull-up diaper is because adopted four rubber bands, and its absorption rate, diffusion rate are all very fast moreover, and pulling force is just not a problem, as long as diffusion rate satisfies the demand can, the distribution of pulling force can also be realized better to the mode of equipartition for the effect of bearing is better. It is also more even for the profile.
6. Because the unreeling is different from the unreeling of the two existing rubber bands, the structure of the unreeling device needs to be correspondingly improved. In this scheme, adopted first S-shaped to apply mechanism, second S-shaped to apply the mechanism, utilized first S-shaped to apply mechanism input first rubber band, second rubber band on the substrate material, utilized second S-shaped to apply mechanism input third rubber band, fourth rubber band on the substrate material for first rubber band, second rubber band, third rubber band, fourth rubber band form wavy curve. Specifically, the guide control of the first rubber band and the second rubber band is realized through an auxiliary servo motor and an auxiliary rotating rod, and the rubber band is moved in a large direction by utilizing a main servo motor and a main rotating rod. In addition, due to the problem of pulling force, the main rotating rod is configured, so that balance can be effectively realized, rubber bands can be better applied, and the service life is longer. In addition, the ratio of the angular velocity of the rotation of the auxiliary rotating rod to the angular velocity of the rotation of the main rotating rod is 1: (1.5-3), its numerical value can set up according to actual need, should not too big nor too little of the specific value of the angular velocity of rotation usually, too big can lead to the elastic ribbon to exert the time can not reach better control, and too little can lead to the deformation of elastic ribbon.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
