Description

Technical Field

[0001] The utility model relates to the technical field of disposable hygiene product manufacturing equipment, especially diapers, pull-up pants, women's sanitary pants, sanitary napkins, pads, etc., and specifically relates to a raw material fixed-length cutting and non-glue compounding device. Background Art

[0002] Disposable hygiene products (such as disposable diapers) are composed of multiple materials compounded together. In disposable diapers (specifically, it can be diapers, pull-up pants, etc.), fixed-length materials (such as conductive layer materials, etc.) are usually intermittently arranged in the material compounding layer. In order to realize the compounding of the fixed-length materials in the product, a gluing device is usually arranged in the disposable hygiene product manufacturing equipment, which is used to apply glue to the continuously moving first raw material, and then transfer the glued first raw material into the cutting device, and perform fixed-length cutting on the first raw material to obtain short sheets of the first raw material. Finally, the short sheets of the first raw material are adsorbed and transferred to the second raw material (or semi-finished product of the product) and bonded and compounded with it, thus completing the fixed-length cutting and compounding process of the first raw material.

[0003] In the above process, the cut short sheets of the first raw material are coated with hot melt glue by the gluing device and bonded and compounded with the second raw material (or semi-finished product of the product). Due to the use of hot melt glue, the semi-finished product after compounding is prone to hardening, affecting comfort. Moreover, hot melt glue is relatively expensive, resulting in a higher production cost for disposable hygiene products. In addition, hot melt glue is not easily degraded and will cause certain pollution to the environment.

[0004] In addition, in the existing compounding process of fixed-length materials, the gluing device, cutting device, and compounding device are usually arranged at workstations in different units, which easily leads to an increase in the length of the entire production line and the number of process workstations, thus increasing the manufacturing cost.

[0005] Therefore, a solution needs to be proposed for the problems in the existing technology. Summary of the Utility Model

[0042] The following will detail a raw material fixed-length cutting and non-glue compounding device provided in the embodiments of the present utility model. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present utility model. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0043] Refer to Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, a raw material fixed-length cutting and non-glue compounding device is provided. The device includes a guide roller 1, a conveying device 2, and a cutting and compounding device 3. Among them, the guide roller 1 is arranged at the working stations that need to be guided throughout the process. The conveying device 2 is arranged on the upstream side of the cutting and compounding device 3. As Figure 1 shown, the continuously pulled first sheet W1 is conveyed to the conveying device 2 under the guidance of the guide roller 1. The conveying device 2 includes a hollow vacuum box structure and is connected to an external air suction device (including an air duct, a vacuum generator, etc., not shown in the figure), and introduces negative pressure gas into the vacuum box for adsorbing and conveying the first sheet W1. Thus, the first sheet W1 adsorbed and conveyed by the conveying device 2 is conveyed to the cutting and compounding device 3.

[0044] Continuing to refer to Figure 1 and Figure 2 shown, the cutting and compounding device 3 has a first direction X (the first direction is the transverse direction in this embodiment), a second direction Y (the second direction is the longitudinal direction in this embodiment), and a third direction Z (the third direction is the axial direction in this embodiment) that are perpendicular to each other. The cutting and compounding device 3 includes a cutting knife roller 31, a bottom roller 32, an embossing roller 33, a power member 35, a frame 36, a driving part 37, and a transmission part 38. Among them, the cutting knife roller 31, the bottom roller 32, and the embossing roller 33 are all installed in the same frame unit 36.

[0045] Specifically, the cutting knife roller 31 and the bottom roller 32 are correspondingly arranged. The cutting knife roller 31 includes a core shaft 311 and at least one blade 312 arranged on the outer periphery of the core shaft 311 in the radial direction. Among them, the blade 312 can be adjustably fixed on the core shaft 311 by means of a fixture or the like. Further, the blade 312 can be adjusted in the radial direction of the core shaft 311. In this embodiment, the number of blades 312 is 2. Of course, the number of blades 312 can be calculated and determined according to the preset size (specifically the preset length L, and the preset length L is fixed) that the first sheet W1 needs to be cut into.

[0046] As shown Figure 1 in the figure, the connecting line between the axis of the cutting roller 31 and the axis of the bottom roller 32 passes through the cutting edge of the blade 312 of the cutting roller 31, and the angle α formed by the connecting line between the axis of the cutting roller 31 and the axis of the bottom roller 32 and the longitudinal direction Y is an acute angle, that is, the angle α < 90°. The cutting edge of the blade 312 is arranged corresponding to the bottom roller 32. That is, when the cutting edge of the blade 312 abuts against the bottom roller 32, the continuously drawn first sheet W1 is cut into the first short sheet W11. In this way, the first sheet W1 can be effectively cut.

[0047] In this embodiment, the bottom roller 32 has a drum-like structure, and a plurality of through holes 321 are formed on the surface of the bottom roller 32. As shown Figure 2 in the figure, these through holes 321 are evenly distributed on the surface of the bottom roller 32 according to the size of the first short sheet W11. An air vent passage (not shown in the figure) is provided inside the bottom roller 32, and the air vent passage is communicated with the through holes 321. An air distribution plate 34 is provided at the end of the bottom roller 32 along the third direction Z (i.e., the axial direction). The air distribution plate 34 is connected to an air suction device (including an air duct, a vacuum generator, etc., not shown in the figure), and the air suction device is communicated with the air vent passage inside the bottom roller 32 through the air distribution plate 34. In this way, the negative pressure gas generated by the air suction device can be transmitted to the through holes 321 through the air distribution plate 34 and the air vent passage to adsorb and convey the first short sheet W11. It should be noted that the air distribution plate 34 is fixed and can be arranged at one end of the bottom roller 32 along the axial direction Z, or can be arranged at both ends of the bottom roller 32 along the axial direction Z. The air distribution plate 34 has a negative pressure passage inside, and the setting area of the negative pressure passage is between the blade 312 and the embossing roller 33, as shown Figure 1 in the angle β in the figure. When the bottom roller 32 rotates to the setting area corresponding to the negative pressure passage of the air distribution plate 34, the first short sheet W11 is adsorbed on the through holes 321 and is conveyed to the embossing roller 33 along with the rotation of the bottom roller 32 (this process can also be called transfer printing). That is, when the first sheet W1 is cut into the first short sheet W11 by the blade 312, the first short sheet W11 is adsorbed on the through holes 321 under the action of negative pressure and is conveyed to the downstream side.

[0048] As shown Figure 1 and Figure 3 in the figure, an embossing roller 33 is arranged on the opposite side of the bottom roller 32. Along the third direction Z (here it is the axial direction), the middle position of the embossing roller 33 along the axial direction Z is defined as the working area D. In this working area D, the embossing roller 33 includes a base 331 and a flower-shaped convex part 332 protruding from the base 331 along the circumferential direction, as shown Figure 2 、 Figure 3 and Figure 4As shown. The flower-shaped convex part 332 can be designed into various shapes, and its cross-sectional shape can be one of a circle, an ellipse, and a polygon. Among them, the polygon can include quadrilaterals such as a square, a rectangle, and a rhombus, and can also include polygons such as a trapezoid. In this embodiment, the cross-sectional shape of the flower-shaped convex part 332 is a circle. Further, a plurality of flower-shaped convex parts 332 are arranged according to a preset rule to form a group of flower patterns T, and the preset rule can be set according to actual needs. Further, at least one group of flower patterns T is arranged on the outer circumference of the embossing roller 33, as Figure 4 shown. In this embodiment, the number of groups of the flower patterns T is 2 groups. Of course, the number of groups of the flower patterns T can be determined according to the preset size L (the preset size has a fixed length) of the first short sheet W11 and the diameter of the embossing roller 33.

[0049] As Figure 1 shown, in this embodiment, along the second direction Y (here is the longitudinal direction), the axis of the embossing roller 33 and the axis of the bottom roller 32 are arranged on the same horizontal line to ensure the effect of embossing and laminating.

[0050] There is a gap between the bottom roller 32 and the embossing roller 33 for the first short sheet W11 and the second sheet W2 to pass through. When the cut first short sheet W11 is adsorbed on the through hole 321 under negative pressure and is conveyed to the position of the embossing roller 33, at the same time, the continuously pulled second sheet W2 fed from the downstream side is also conveyed to the position of the embossing roller 33. As the embossing roller 33 rotates, the first short sheet W11 is laminated on the second sheet W2 in a non-adhesive manner, thereby forming a composite sheet (semi-finished product). During this process, the second sheet W2 is guided to the required position by the guide roller 1. As Figure 5 shown, the first sheet W1 is cut into the first short sheet W11, and the length of the first short sheet W11 is L. When the first short sheet W11 is laminated on the second sheet W2, the flower-shaped convex part 332 of the embossing roller 33 correspondingly forms a joint part F1 on the composite sheet, as Figure 5 shown, the flower pattern T of the embossing roller 33 correspondingly forms a composite pattern F on the composite sheet.

[0051] Further, in this embodiment, a heater (not shown in the figure) is provided inside the embossing roller 33, and the materials are laminated by hot pressing, so that the embossing and laminating of the embossing roller 33 achieve a better effect. The first short sheet W11 and the second sheet W2 are laminated in a non-adhesive manner by the embossing roller 33, and the embossing roller 33 with a unique flower design is used to realize the lamination of the materials. In this way, various composite patterns F can be formed on the material surface while laminating the materials, thereby enhancing the comfort of the material and increasing the beauty of the product, and also making a great contribution to environmental protection.

[0052] In this embodiment, on one side of the frame unit close to the embossing roller 33 (such asFigure 1 As shown in the figure, a power member 35 is provided on the side of the embossing roller 33 away from the bottom roller 32. The power member 35 is connected to the embossing roller 33 through a screw rod to adjust the gap between the embossing roller 33 and the bottom roller 32. Among them, the power member 35 can specifically be a cylinder, a hydraulic cylinder, etc. By adjusting the power member 35, the acting force of the embossing roller 33 on the bottom roller 32 (that is, changing its pressing force) can be changed, so that a composite sheet (semi-finished product) that meets the composite requirements can be processed.

[0053] Refer to Figure 2 As shown in the figure, a driving part 37 is provided on one side of the bottom roller 32 along the axial direction Z. The driving part 37 provides a driving force to the bottom roller 32 to make the bottom roller 32 rotate. A transmission part 38 is provided on the other side of the bottom roller 32 along the axial direction Z. The transmission part 38 includes a first transmission part 381 connected to the bottom roller 32, a second transmission part 382 connected to the cutter roller 31, and a third transmission part 383 connected to the embossing roller 33. Among them, the first transmission part 381 is connected to the second transmission part 382, the second transmission part 382 is connected to the third transmission part 383, and along the axial direction Z, the first transmission part 381, the second transmission part 382, and the third transmission part 383 are correspondingly arranged. Such a design can achieve that when the driving part 37 drives the bottom roller 32, the cutter roller 31 and the embossing roller 33 are simultaneously driven to rotate.

[0054] In addition, in this embodiment, guide rings 333 are provided at both ends of the working area D of the embossing roller 33 along the axial direction Z of the embossing roller 33, as Figure 3 shown in the figure. Among them, the radial dimension of the guide ring 333 is equal to or slightly smaller than the radial dimension of the flower-shaped convex part 332. By providing the guide rings 333, the positioning of the embossing roller 33 and the bottom roller 32 along the axial direction Z can be realized, and at the same time, the pressure of the flower-shaped convex part 332 of the embossing roller 33 on the bottom roller 32 can be relieved, thereby effectively protecting the flower-shaped convex part 332.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
