Furthermore it is also possible to which the embossing device setting in the utility model can carry out the axial position of the second roller 22 The adjustment device of adjustment, thus when the knot of positioning pin 37 and dowel hole 36 during assembling the first roller 21 and the second roller 22 Close the fine tuning that can be realized using adjustment device when there is deviation to 36 axial position of dowel hole on the second roller 22.As adjustment One example of device, as shown in Fig. 2, can be used for example by fine adjustment bolt 41 and the fine adjustment being screwed with it Device is adjusted composed by block 40 and mounting blocks 39, by the adjustment to the fine adjustment bolt 41 in fine adjustment block 40, Come the position in 22 axial direction of the second roller of fine adjustment, the accurate combination of positioning pin 37 Yu dowel hole 36 is realized with this, thus The position of engagement for capableing of protrusion 32 and the shrinkage pool portion 33 of the first roller 21 to the second roller 22 is positioned in axial and circumferential.
In addition, as shown in Fig. 2, holding the axially external setting air draught block 38 of lead ring, and by air draught block 38 and the first roller 21 The bottom in shrinkage pool portion 33 is connected, for example, through hole can be arranged in the bottom in shrinkage pool portion 33, air draught block 38 is via the through hole And access etc. is connected to the bottom in shrinkage pool portion 33.Air draught in order to realize the air suction function in preset range, in shaft end two sides The gas source that the axially external setting of block 38 can preset air draught range imports part (not shown), and through hole and the gas source of air draught block 38 are led Enter the connection of part preset air draught range areas, gas source imports part external air intake device (blower, figure in do not show) again.Above setting Mode can carry out air draught (pumping) in shrinkage pool portion 33 via the bottom in shrinkage pool portion 33 by air draught block 38, as a result, to first It, can will be by protrusion 32 the using the air draught effect of the external air intake device of air draught block 38 when non-woven fabrics W1 carries out three-dimensional figuration The inner wall that protrusion is adsorbed on shrinkage pool portion 33 is formed by one non-woven fabrics W1, so as to keep the form for being formed by protrusion So that it will not deform because of reasons such as external force, and the multiple protrusions to be formed can be made to keep uniform, it is ensured that realize the first nothing The three-dimensional figuration of woven fabric W1.The embossing device of the utility model, air draught model of the air draught block 38 in the circumferential direction of the first roller 21 Enclose be not the first roller 21 complete cycle.In embossing device shown in Fig. 1, air draught range is substantially along the rotation of the first roller 21 Turn direction from the position of engagement of the first roller 21 and the second roller 22 to the abutted position of the first roller 21 and the second smooth roll 24.Above-mentioned air draught Range be by gas source import part air draught setting range depending on, under actual conditions the air draught range can according to different factors and It suitably changes.
In addition, such as Fig. 2, Fig. 3, Fig. 5, Fig. 7 (a), shown in Fig. 7 (b), the embossing device of the utility model also has pair Multiple temperature sensors 34,44 that the temperature of each roller is detected.The temperature sensor 34 of first roller 21 uses contactless temperature Sensor is spent, raised flower pattern 31 is arranged on and holds between lead ring 35 and is located at the radial outside of the first roller 21 close to radial end face Position, such as the position of distance the first roller radial end face 10mm~20mm.But temperature sensor 34 and the first roller 21 away from From without being limited thereto, as long as in its detection range.Non-woven fabrics is sealed when using the first roller 21 and the first smooth roll 23 When bonding, raised flower pattern 31 is needed to be maintained at suitable temperature, the temperature of raised flower pattern 31 it is too low or it is excessively high can be to the first nonwoven Cloth W1 and the heat-sealing bonding effect of the second non-woven fabrics W2 impact, and occur that heat-seal bond strength is non-uniform to be happened, very There is the non-uniform phenomenon of pliability to first non-woven fabrics W1 solid figuration (protrusion) portion that will cause to occur, when raised flower pattern 31 Temperature is excessively high, the pliability of the first non-woven fabrics W1 lug boss can be reduced, as sanitary napkin, paper diaper surface layer material in use, shadow Ring wearing comfort, it is therefore necessary to control the temperature of raised flower pattern 31.Have in the prior art by the temperature of the first roller The situation of the inside of each roller is arranged in sensor, but at this time because cannot especially cannot be close to being sealed close to raised flower pattern 31 The surface of the raised flower pattern 31 of bonding measures temperature, therefore can not accurately grasp the temperature of raised flower pattern 31.In addition, due to The inside of each roller is additionally provided with heating rod for heating, and therefore, being equally also disposed at the temperature sensor inside roller will receive The interference of heating rod and accurately the surface temperature of raised flower pattern for being located at outermost radial outside cannot be measured.It is practical at this In novel, as shown in Fig. 2, because the temperature sensor 34 of the first roller 21 be arranged on raised flower pattern 31 and hold between lead ring 35 and Radial outside positioned at the first roller 21 is close to the position of radial end face, so temperature sensor 34 is closer to needing to carry out temperature The raised flower pattern 31 of control, therefore the surface temperature of raised flower pattern 31 can be accurately grasped, be conducive to heat-sealing bonding.In addition, such as Shown in Fig. 2, Fig. 5, Fig. 7 (a), Fig. 7 (b), the temperature sensor 44 of the second roller 22 and the first smooth roll 23 is arranged on the inside of roller It is contact type temperature sensor close to the position of radial end face.
In addition, when embossing device is provided with air draught block 38, if being arranged the temperature sensor of the first roller in roller Inside, then be located at roller inside temperature sensor detection temperature also suffer from air draught block 38 formed wind flowing influence And become inaccuracy.In the present invention, by by the setting of the temperature sensor 34 of the first roller 21 raised flower pattern 31 with hold Radial outside between lead ring 35 and positioned at the first roller 21 can not only be close to raised flower pattern 31 close to the position of radial end face Surface heat-sealing bonding is carried out to raised flower pattern 31 surface nearby carry out thermometric, and because far from air draught block 38, also The flow effect for the wind not generated by air draught block 38, measures so as to the surface temperature accurately to raised flower pattern 31.
In the present invention, as shown in Figure 1, the transport path along non-woven fabrics is further set in the downstream of the first smooth roll 23 The second smooth roll 24 is set, it is viscous further to carry out heat-sealing to the first non-woven fabrics W1 and the second non-woven fabrics W2 by the second smooth roll 24 of setting It closes.At this point, by the first non-woven fabrics W1 after three-dimensional figuration further together with the second non-woven fabrics W2 that another conveying comes by across The first roller 21 and the first smooth roll 23 and the first roller 21 and the second smooth roll that first non-woven fabrics W1 and the second non-woven fabrics W2 are abutted against Between 24, at the same position of raised flower pattern 31, embossing is sealed twice and forms embossing non-woven fabrics 10 together, To obtain more firm heat-seal bond strength, and the higher speed of production of embossing device can be obtained.
The transport path that this concludes the description of in non-woven fabrics is provided with 24 the two smooth rolls of the first smooth roll 23 and the second smooth roll Embodiment, but the embodiments of the present invention is without being limited thereto, is also possible to only be arranged in the transport path of non-woven fabrics One smooth roll 23.Alternatively, it is also possible to only carry out convex-concave without using the second nonwoven layer W2 to the first non-woven fabrics W1 and be embossed to form list The embossing non-woven fabrics of layer material.At this point, the raised flower pattern 31 of the first roller 21 is by being built in the heating of the inside of the first roller 21 Device and be pre-heated to the first predetermined temperature, the first smooth roll 23 is and being arranged in internal heater (such as heating rod etc.) It is pre-heated to third predetermined temperature.It is viscous due to not needing to obtain higher heat-sealing in only the first non-woven fabrics W1 Close intensity, it is generally the case that the first non-woven fabrics W1 is able to maintain that stereo concave-convex after third predetermined temperature need to only reach three-dimensional figuration The heat-sealing setting temperature of effect, the temperature can be less than or equal to the melting temperature of the first non-woven fabrics W1.

The manufacturer of the non-woven fabrics with embossing is manufactured to the embossing device of the utility model is used below One specific example of method is described in detail.
The manufacturing method of the non-woven fabrics with embossing is pressed using the bumps of the utility model being illustrated above Embossing device carries out three-dimensional figuration to non-woven fabrics, to being sealed by the non-woven fabrics of three-dimensional figuration.The manufacturing method includes Three-dimensional figuration process, in the solid figuration process, using the first roller 21 and 22 pairs of the second roller conveyings come in the conveying direction Continuous first non-woven fabrics W1 carries out three-dimensional figuration, forms protrusion on first non-woven fabrics W1.
Then, heat-sealing process is carried out, in the heat-sealing process, such as the raised flower pattern 31 and the first light that pass through the first roller 21 Roller 23 cooperates to the second non-woven fabrics W2 progress heat-sealing bonding come by the above-mentioned first non-woven fabrics W1 of three-dimensional figuration and rear conveying. In the method, the second non-woven fabrics W2 is not required, can also be only hot to being carried out by the first non-woven fabrics W1 of three-dimensional figuration Envelope.
In the installation and debugging stage of embossing device, or need positioning to first roller 21 and the second roller 22 into The first calibration positioning process is carried out when row adjustment.When needs mentioned here are adjusted positioning, when e.g. passing through one section Between operation after when being safeguarded to embossing device.In the first calibration positioning process, such as utilize 37 He of positioning pin The cooperation of dowel hole 36 carries out calibration positioning to the first roller 21 and the second roller 22 on circumferential and axial, and can be sharp simultaneously Calibration positioning is carried out to the first roller 21 and the second roller 22 radially with lead ring 35 is held.Utilizing positioning pin 37 and dowel hole 36 After having carried out calibration positioning, positioning pin 37 is extracted from dowel hole 36.
Equally in the installation and debugging stage of embossing device, or need to first roller 21 and the first smooth roll 23 When positioning is adjusted, the second calibration positioning process is carried out.Lead ring is held in the second calibration positioning process, such as using above-mentioned 35 pair of first roller 21 and the first smooth roll 23 carry out calibration positioning.In the method, the second calibration positioning process is not required, The first calibration positioning process can only be carried out.
In addition, manufacturing the manufacturing method of the non-woven fabrics with embossing using the embossing device of the utility model also With thermometric process, which implements in the manufacturing process of the non-woven fabrics with embossing, at least using contactless Temperature sensor measures the surface temperature of the first roller 21, and the thermometric process can be in the non-woven fabrics with embossing Manufacturing process in temperature is detected in real time.
It is accurately positioned between the first roller and the second roller, the first roller and smooth roll due to not being directed in the prior art, Will appear following problem: non-woven fabrics is easy to be wound in the raised flower pattern of the first roller, and the raised flower pattern of the first roller is easy to fall off, the The protrusion of two rollers is easy broken needle, and protrusion can not be formed on the first non-woven fabrics, and protrusion is possible to pierce through the first non-woven fabrics, can not be right First non-woven fabrics and the second non-woven fabrics carry out heat-sealing bonding, and the problems such as fold occurs in the first non-woven fabrics during three-dimensional figuration. In addition, pressure generally all directly acts on the raised flower pattern of the first roller, and it is therefore possible to lead to flower pattern when carrying out heat-sealing bonding It falls off, the problems such as non-woven fabrics is wrapped in raised flower pattern.
In the manufacturing method for manufacturing the non-woven fabrics with embossing using the embossing device of the utility model, because To calibrate positioning process with first, so can ensure that the first roller 21 and the second roller 22 are in axial direction, circumferential direction, diameter in three-dimensional figuration Upward accurate positionin, therefore the protrusion 32 of the second roller 22 can be properly inserted in the shrinkage pool portion 33 of the first roller 21, it will not Occur that such as non-woven fabrics in the prior art is easy to be wound in raised flower pattern, the raised flower pattern of the first roller is easy to fall off, the second roller Protrusion be easy broken needle, the problems such as piercing through the first non-woven fabrics can not be possible to forming concave-convex pattern, protrusion on the first non-woven fabrics.
In addition, the temperature of the first roller is highly prone to external influence in the manufacturing process of the non-woven fabrics with embossing It (is such as influenced by the flowing for the wind that air draught block 38 is formed) with interference, still, the prior art can not be grasped accurately in manufacturing process Each roller temperature, the especially temperature of the first roller.In the manufacturing method using the embossing device of the utility model, Because having thermometric process, the temperature change of each roller can be accurately measured, especially for the first roller 21, use is non- Contact type temperature sensor measures the surface temperature of the first roller 21, can control in real time temperature.
The manufacturing method that the non-woven fabrics with embossing is manufactured using the embossing device of the utility model can be with With air draught process, air-breathing is carried out to shrinkage pool portion 33 by the lower part via shrinkage pool portion 33, and can be in three-dimensional figuration process In the shape of protrusion that is formed on the first non-woven fabrics W1 by three-dimensional figuration consolidated and kept so that protrusion will not go out The case where now collapsing, and because thermometric process is detected to the surface temperature of raised flower pattern 31, in shrinkage pool portion 31 The air draught process of interior implementation will not influence the precision of thermometric process.It and is to be carried out from the inside of roller to temperature in the prior art Detection, so if wishing to ensure that the protrusion of non-woven fabrics, it is likely that temperature detecting precision is influenced, if to guarantee temperature detection Precision can not be then kept fixed using protrusion of the air draught process to non-woven fabrics.
Described above is the embossing device using the utility model to manufacture the non-woven fabrics with embossing One example of manufacturing method can carry out various modifications to it.Such as it can be carried out again after heat-sealing bonding process Heat-sealing bonding can obtain the higher speed of production of embossing device to consolidate heat-sealing bonding effect.
