[0020] The following is combined with Figures 1 to 4 This utility model describes a printing and laminating equipment for producing double-layer nonwoven fabric, including a workbench 1, a first fabric roll 2, a second fabric roll 3, a first sparse fabric assembly 4, a second sparse fabric assembly 5, a transition roller assembly 6, an embossing mechanism 7, an ultrasonic laminating mechanism 8, a cooling mechanism 9, and a winding mechanism 10. The first fabric roll 2 and the second fabric roll 3 are respectively disposed on one side of the workbench 1. The first sparse fabric assembly 4, the second sparse fabric assembly 5, the transition roller assembly 6, the embossing mechanism 7, the ultrasonic composite mechanism 8, the winding mechanism 10 and the cooling mechanism 9 are respectively disposed on the workbench 1. The first sparse fabric assembly 4 is disposed at the output end of the first fabric roll 2, and the second sparse fabric assembly 5 is disposed at the output end of the second fabric roll 3; the transition roller assembly 6 is disposed on one side of the first sparse fabric assembly 4; The embossing mechanism 7 is located at the output end of the transition roller assembly 6, and the ultrasonic composite mechanism 8 is located above the embossing mechanism 7. The embossing mechanism 7 includes an embossing bracket 71, an embossing roller 72, a rotating roller 73, and a drive assembly 74. The embossing roller 72 and the rotating roller 73 are rotatably mounted on the embossing bracket 71, and the rotating roller 73 and the embossing roller 72 are mutually abutting. The rotating roller 73 is connected to the drive end of the drive assembly 74. One end of the embossing roller 72 is provided with a driven gear 721, and one end of the rotating roller 73 is provided with a driving gear 731. The driving gear 731 is meshed with the driven gear 721.

[0021] Currently, nonwoven fabrics used in hygiene products such as diapers and sanitary napkins often require a printed layer to improve comfort and absorbency. This print raises the printed areas, enhancing skin comfort and absorbency. However, existing technologies using single-layer nonwoven printing often produce poor results, with indistinct print elevations, a tendency to collapse, and poor skin comfort. While double-layer nonwoven fabric lamination is possible, current techniques typically use adhesives to bond the fabrics. These adhesives have strong odors and contain chemicals, negatively impacting user experience and health. Furthermore, the process generates harmful gases, affecting worker health. In this embodiment, the working principle is as follows: The first layer of nonwoven fabric is discharged from the first fabric roll 2 and enters the first loosening assembly 4. After being loosened by the first loosening assembly 4, the nonwoven fabric enters the transition roller assembly 6. After being pulled by the transition roller assembly 6, it passes through the embossing roller 72 of the embossing mechanism 7 and enters below the output end of the ultrasonic composite mechanism 8. At this time, the second layer of nonwoven fabric is discharged from the second fabric roll 3 and enters the second loosening assembly 5. After being loosened by the second loosening assembly 5, the nonwoven fabric enters the transition roller assembly 6. After being pulled by the transition roller assembly 6, it enters between the embossing roller 72 and the rotating roller 73 of the embossing mechanism 7. The rotating roller 73 and the embossing roller 72 are arranged to press against each other. One end of the embossing roller 72 is provided with a driven gear 721, and one end of the rotating roller 73 is provided with a driven gear 721. With a drive gear 731, when the drive assembly 74 drives the rotating roller 73 to rotate, the drive gear 731 meshes with the driven gear 721, and the embossing roller 72 rotates synchronously with the rotating roller 73, thereby embossing the second layer of nonwoven fabric between the embossing roller 72 and the rotating roller 73. After embossing, the second layer of nonwoven fabric enters below the output end of the ultrasonic composite mechanism 8 along the rotating roller 73 and is bonded to the first layer of nonwoven fabric. The two layers of nonwoven fabric are then bonded together by the ultrasonic composite mechanism 8, so that the first layer of nonwoven fabric and the second layer of nonwoven fabric are tightly bonded together to form a double-layer nonwoven fabric. The double-layer nonwoven fabric is cooled by the cooling mechanism 9, and the bonding point is quickly cooled and shaped. Finally, it enters the winding mechanism 10, which winds up the double-layer nonwoven fabric. This equipment produces a double-layer nonwoven printed composite fabric layer, which not only has a good printing effect and obvious printing relief, forming a stable air layer, but also provides a comfortable feel against the skin and helps improve water absorption. Furthermore, this equipment uses ultrasonic bonding to bond the nonwoven fabric with ultrasound, eliminating the need for adhesive materials, and producing no chemicals or odors. This improves the user experience of hygiene products and ensures safety and health. Moreover, no harmful gases are produced during the operation, which could affect the health of workers.

[0022] Furthermore, the ultrasonic composite mechanism 8 includes a composite support 81, a lifting drive 82, a lifting platform 83, several guide columns 84, and an ultrasonic generator 85; the composite support 81 is disposed above the embossed support 71. A plurality of guide posts 84 are disposed between the composite bracket 81 and the embossing bracket 71, and the lifting platform 83 is slidably disposed on the guide posts 84 in the vertical direction; the lifting drive component 82 is disposed above the composite bracket 81, and the lifting platform 83 is disposed at the output end of the lifting drive component 82; the upper end face of the embossing bracket 71 is provided with a lifting hole 711, and the lifting platform 83 moves up and down within the lifting hole 711; the ultrasonic generator 85 is disposed on the lifting platform 83.

[0023] Specifically, in this embodiment, the working principle is as follows: the two ends of the guide post 84 are respectively connected to the top of the composite bracket 81 and the top of the embossed bracket 71. Perforations are provided at the four corners of the lifting platform 83, and these perforations fit around the outer periphery of the guide post 84, thereby ensuring that all four corners of the lifting platform 83 are guided by the guide post 84, guaranteeing the horizontal and stable movement of the lifting platform 83 during lifting. The output end of the lifting drive component 82 is fixedly connected to the top of the lifting platform 83. The lifting drive component 82 can be a cylinder, electric cylinder, or other drive component. The lifting drive component 82 drives the lifting platform 83 to move up and down along the guide post 84, thereby bringing the ultrasonic generator 85 mounted on the lifting platform 83 closer to its rotation. Roller 73, after the first layer of nonwoven fabric and the printed second layer of nonwoven fabric are laminated together in the previous process to form a double-layer nonwoven fabric, rotates along the roller 73. When it passes the ultrasonic generator 85, the ultrasonic generator 85 will be activated and will intermittently fuse the double-layer nonwoven fabric seamlessly. The high-frequency vibration and friction of the ultrasonic waves will generate heat to bond the two layers of nonwoven fabric together. No adhesive materials are needed for bonding, there are no chemical substances or odors, which improves people's experience of using hygiene products and ensures people's safety and health. Moreover, no harmful gases will be generated during the operation, which may affect the health of workers.

[0024] Furthermore, the drive assembly 74 includes a drive motor 741, a transmission chain 742, a drive sprocket 743, a driven sprocket 744, a tension sprocket 745, and a traction sprocket 746. A traction roller 11 is provided between the ultrasonic composite mechanism 8 and the winding mechanism 10, and the traction sprocket 746 is located at one end of the traction roller 11. The drive motor 741 is located below the worktable 1, the drive sprocket 743 is located at the output end of the drive motor 741, the driven sprocket 744 is located at one end of the rotating roller 73, the tension sprocket 745 is located on the worktable 1, and the transmission chain 742 is sequentially connected to the drive sprocket 743, the tension sprocket 745, the driven sprocket 744 and the traction sprocket 746.

[0025] Specifically, the working principle of this embodiment is as follows: The drive motor 741 starts, driving the drive sprocket 743 to rotate. The transmission chain 742 forms a closed loop around the drive sprocket 743, tension sprocket 745, driven sprocket 744, and traction sprocket 746. The rotation of the drive sprocket 743 drives the transmission chain 742, thereby synchronously driving the tension sprocket 745, driven sprocket 744, and traction sprocket 746 to rotate. The traction sprocket 746 drives the traction roller to rotate, thus causing the traction roller to transport the nonwoven fabric. The tension sprocket 745 is installed on... On the workbench 1, the installation position of the transmission chain 742 can be adjusted according to the tension of the transmission chain 742 to maintain the tension of the transmission chain 742; the driven sprocket 744 is installed on the rotating roller 73, and the rotation of the driven sprocket 744 will drive the rotating roller 73 to rotate, thereby driving the embossing roller 72 to rotate synchronously with the rotating roller 73 to perform embossing operations through the meshing of the drive gear 731 and the driven gear 721. The synchronous transmission through the transmission chain 742 also drives the traction sprocket 746, the rotating roller 73 and the embossing roller 72, resulting in stable transmission.

[0026] Furthermore, the cooling mechanism 9 includes a mounting base 91 and a plurality of cooling fans 92; the mounting base 91 is disposed at the upper end of the embossing bracket 71, the mounting base 91 is set at an angle to the top surface of the embossing bracket 71, the mounting base 91 faces the output end of the rotating roller 73, and the cooling fans 92 are arranged on the mounting base 91.

[0027] Specifically, in this embodiment, after ultrasonic bonding, the double-layer nonwoven fabric is heat-melted. To avoid deformation caused by pulling or other reasons, the double-layer nonwoven fabric is cooled by air by a cooling fan 92. The cooling fan 92 is installed on the mounting base 91 and faces the bonding point of the nonwoven fabric by the ultrasonic bonding mechanism 8. The cooling fan 92 cools the nonwoven fabric immediately after ultrasonic bonding, so that the heat-melted nonwoven fabric can be quickly solidified and stabilized, avoiding the problem of pulling and deformation.

[0028] Furthermore, the front end of the first sparse distribution assembly 4 is provided with a guide assembly 12, which includes a first guide roller 121, a second guide roller 122, a third guide roller 123 and a fourth guide roller 124. The first guide roller 121 and the second guide roller 122 are located on the same vertical plane, and the third guide roller 123 and the fourth guide roller 124 are located on the same vertical plane. The nonwoven fabric of the first roll 2 is fed into the first sparse fabric assembly 4 after passing over the first guide roller 121 and the third guide roller 123, and the nonwoven fabric of the second roll 3 is fed into the second sparse fabric assembly 5 after passing over the second guide roller 122 and the fourth guide roller 124.

[0029] Specifically, the working principle of this embodiment is as follows: the first layer of nonwoven fabric coming out of the first roll 2 passes over the upper side of the first guide roller 121, then passes over the lower side of the third guide roller 123, and then enters the first sparse fabric assembly 4; the second layer of nonwoven fabric coming out of the second roll 3 passes over the lower side of the second guide roller 122, then passes over the upper side of the fourth guide roller 124, and then enters the second sparse fabric assembly 5. The first guide roller 121, the second guide roller 122, the third guide roller 123 and the fourth guide roller 124 guide the first layer of nonwoven fabric and the second layer of nonwoven fabric respectively to prevent the nonwoven fabric from shifting.

[0030] Furthermore, the first sizing assembly 4 is disposed above the workbench 1, and the second sizing assembly 5 is disposed below the workbench 1. The first sizing assembly 4 and the second sizing assembly 5 each include four support columns 41, a sizing table 42, and two sizing rollers 43. The sizing table 42 of the first sizing assembly 4 is fixedly connected to the top surface of the workbench 1 through the four support columns 41, and the sizing table 42 of the second sizing assembly 5 is fixedly connected to the bottom surface of the workbench 1 through the four support columns 41. The two sizing rollers 43 are rotatably disposed at both ends of the sizing table 42.

[0031] Specifically, in this embodiment, the first sizing assembly 4 and the second sizing assembly 5 have the same structure. The first sizing assembly 4 is located above the workbench 1, and the second sizing assembly 5 is located below the workbench 1. This allows the first layer of nonwoven fabric to enter the first sizing assembly 4 above the workbench 1, and the second layer of nonwoven fabric to enter the second sizing assembly 5 below the workbench 1. The two do not interfere with each other and simultaneously sizing the first and second layers of nonwoven fabric, effectively utilizing space and making the overall structure more compact. The sizing table 42 is installed through the support column 41, and the sizing roller 43 can be installed on the sizing table 42 through bearings. The sizing roller 43 drives the nonwoven fabric to be transported. The sizing roller 43 is a flattening and spreading roller, which can comb the nonwoven fabric, making the nonwoven fabric spread out and avoiding overlapping.

[0032] Furthermore, a fabric roll box 101 is provided on one side of the workbench 1, and the first fabric roll 2 and the second fabric roll 3 are respectively rotatably disposed in the fabric roll box 101. A first fabric outlet 102 and a second fabric outlet 103 are respectively provided on one side of the fabric roll box 101, and a first baffle 104 and a second baffle 105 are respectively provided at the outlets of the first fabric outlet 102 and the second fabric outlet 103.

[0033] Specifically, in this embodiment, the first fabric roll 2 and the second fabric roll 3 are rotatably installed inside the fabric roll box 101. The vertical arrangement allows the nonwoven fabric to be discharged synchronously. The first layer of nonwoven fabric of the first fabric roll 2 is discharged from the first fabric outlet 102, and the second layer of nonwoven fabric of the second fabric roll 3 is discharged from the second fabric outlet 103. A first baffle 104 and a second baffle 105 are respectively provided at the outlets of the first fabric outlet 102 and the second fabric outlet 103. The first baffle 104 and the second baffle 105 are used to block dust and other debris, reduce the occurrence of debris falling into the fabric roll box 101 and onto the nonwoven fabric, and ensure the cleanliness of the nonwoven fabric.

[0034] Furthermore, a pressing roller 75 is provided above the pressing position of the embossing roller 72 and the rotating roller 73, and a lifting roller 76 is provided at the input end of the embossing roller 72. The two ends of the pressing roller 75 and the lifting roller 76 are respectively rotatably connected to the two sides of the embossing bracket 71.

[0035] Specifically, in this embodiment, the two ends of the pressing roller 75 and the lifting roller 76 can be connected to the embossing bracket 71 through bearings to achieve a rotatable connection. The pressing roller 75 is used to press the two layers of non-woven fabric after embossing, so that the non-woven fabric is pressed on the rotating roller 73. This not only avoids the two layers of non-woven fabric from becoming loose or shifting after embossing, but also ensures the fit between the non-woven fabric and the rotating roller 73, and ensures the traction effect of the rotating roller 73 on the non-woven fabric.

[0036] Furthermore, it also includes a slitting mechanism 13, which is disposed at the output end of the ultrasonic composite mechanism 8. The slitting mechanism 13 includes a slitting fixing frame 131 and a plurality of slitting machines 132. The slitting fixing frame 131 is disposed at the output end of the ultrasonic composite mechanism 8. The traction roller 11 is rotatably disposed in the middle of the slitting fixing frame 131. The slitting machines 132 are arranged above the traction roller 11 along the axial direction of the traction roller 11. The slitting machines 132 are fixedly disposed on the top of the slitting fixing frame 131.

[0037] Specifically, in this embodiment, a slitting mechanism 13 is provided after ultrasonic lamination. This mechanism can be used to cut the laminated double-layer nonwoven fabric to a specific length according to the required size, and then wind it up through the winding mechanism 10. The slitting machine 132 is arranged and installed on the slitting fixing frame 131. The position of the slitting machine 132 can be adjusted according to the size requirements, thereby changing the size of the slitting nonwoven fabric. The slitting machine 132 is located above the traction roller 11. While the nonwoven fabric is being conveyed forward on the traction roller 11, the slitting machine 132 performs slitting operations on the traction roller 11 to ensure the stable completion of the slitting operation.
