The feeding mechanism is located at the output end of the traction mechanism. The slitting mechanism is located at the output end of the feeding mechanism and is used for slitting the ear patch material into individual ear patches. The horizontal adjustment mechanism is located at the output end of the slitting mechanism and is used for redirecting and conveying the slit ear patches. The transfer mechanism is... At the output end of the horizontal adjustment mechanism, the composite mechanism is located at the output end of the transfer mechanism and is used to composite the transferred ear flaps with the conveyed diaper body. The composite mechanism includes several conveying rollers, a belt conveyor assembly, a correction assembly, and ear flap adhesion aids. Each of the conveying rollers is arranged in two rows on both sides of the belt conveyor assembly and is rotatably mounted on the frame for conveying the two waist edges of the diaper body. The correction assembly has two correction rollers, which are spaced apart along the conveying direction of the diaper body. The ear flap adhesion aids are located below the transfer mechanism, and the waist circumference rolling and cutting mechanism is located at the output end of the composite mechanism.

[0006] Furthermore, the waistband rolling cutting mechanism includes a blade holder, a first cutting roller, a second cutting roller, a first bottom roller, a second bottom roller, two first bearing seats, two second bearing seats, two third bearing seats, two fourth bearing seats, two first pressure adjusting components, two second pressure adjusting components, two first spacing adjusting components, and two second spacing adjusting components. The axial ends of the first cutting roller are mounted on the blade holder via two first bearing seats, and the axial ends of the first bottom roller are mounted on the blade holder via two second bearing seats, and are distributed below the first cutting roller. The two first pressure adjusting components are mounted on the blade holder and distributed at the axial ends of the first cutting roller, used to adjust the spacing between the first cutting roller and the first bottom roller. The pressure between the two first gap adjustment components is disposed between the first cutter roller and the first bottom roller to adjust the distance between the first cutter roller and the first bottom roller. The axial ends of the second cutter roller are disposed on the cutter holder through two third bearing seats and are distributed on the transverse side of the first cutter roller.

Specifically, the ear patch unwinding mechanism can stably unwind and transport the ear patch material, and the traction mechanism accurately pulls the ear patch material, ensuring a stable supply of ear patch material in subsequent processes and avoiding production problems caused by material supply interruption or instability. Furthermore, the slitting mechanism... The ear patch material is precisely cut into individual ear patches, and the horizontal adjustment mechanism turns and conveys the cut ear patches, preparing them for subsequent lamination with the diaper body. This ensures that the ear patches are laminated with the diaper body in the correct direction and position, improving lamination accuracy and product quality. The lamination mechanism also ensures the stability of the diaper body during transport. The correction component has two correction rollers spaced apart along the transport direction of the diaper body, effectively correcting any deviation during transport and ensuring accurate lamination of the ear patches. Ear patch adhesion aids are located below the transfer mechanism, helping the ear patches adhere better to the diaper body and improving lamination strength. The waistband cutting mechanism, located at the output end of the lamination mechanism, performs waistband cutting on the laminated diaper, ensuring the product meets design requirements.

[0012] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0013] The embodiment of this utility model is as follows:

[0014] refer to Figure 1 and Figure 2As shown, an ear patch preparation device for trousers includes a frame, an ear patch unwinding mechanism 1, a traction mechanism 2, a feeding mechanism 3, a slitting mechanism 4, a cross-changing mechanism 5, a transfer mechanism 6, a composite mechanism 7, and a waistband rolling and cutting mechanism 8. The ear patch unwinding mechanism 1 is mounted on the frame and is used for unwinding and conveying ear patch material. The traction mechanism 2 is located at the output end of the ear patch unwinding mechanism 1 and is used for traction of the ear patch material. The feeding mechanism 3 is located at the output end of the traction mechanism 2. The slitting mechanism 4 is located at the output end of the feeding mechanism 3 and is used for slitting the ear patch material into individual ear patches.

The composite mechanism 7 is located at the output end of the transfer mechanism 6 and is used to combine the transferred ear tabs with the conveyed diaper body. The composite mechanism 7 includes several conveying rollers 71, a belt conveyor assembly 72, a correction assembly 73, and ear tab adhesion aids 74. Each of the conveying rollers 71 is distributed in two rows on both sides of the belt conveyor assembly 72 and is rotatably mounted on the frame for conveying the two waist edges of the diaper body. The correction assembly 73 has two correction rollers 731, which are spaced apart along the conveying direction of the diaper body. The ear tab adhesion aids 74 is located on the lower side of the transfer mechanism 6, and the waist circumference rolling and cutting mechanism 8 is located at the output end of the composite mechanism 7.

[0015] This diaper ear patch manufacturing device integrates various components on the frame, including an ear patch unwinding mechanism 1, a traction mechanism 2, a feeding mechanism 3, a slitting mechanism 4, a cross-sectional mechanism 5, a transfer mechanism, a composite mechanism 7, and a waistband rolling and cutting mechanism 8. This integrated design reduces material transfer and waiting time between processes, improving production efficiency and lowering production costs. Specifically, the ear patch unwinding mechanism 1 stably unwinds and conveys the ear patch material, while the traction mechanism 2 accurately pulls the material, ensuring a stable supply in subsequent processes and preventing production problems caused by material interruptions or instability. Furthermore, the slitting mechanism 4 precisely cuts the ear patch material into individual pieces. The ear patch and the horizontal adjustment mechanism 5 redirect and transport the slit ear patches, preparing them for subsequent lamination with the diaper body. This ensures the ear patches are laminated with the diaper body in the correct direction and position, improving lamination accuracy and product quality. Simultaneously, the lamination mechanism 7 ensures the stability of the diaper body during transport. The correction component 73 has two correction rollers 731, spaced apart along the transport direction of the diaper body, effectively correcting any deviation during transport and ensuring accurate lamination of the ear patches. The ear patch adhesion aid roller 74, located below the transfer mechanism 6, helps the ear patches adhere better to the diaper body, improving lamination strength. The waistband rolling and cutting mechanism 8, located at the output end of the lamination mechanism 7, performs waistband rolling and cutting on the laminated diaper, ensuring the product meets design requirements.

[0016] Specifically, the waistband rolling cutting mechanism 8 includes a blade holder 81, a first cutting roller 82, a second cutting roller 83, a first bottom roller 84, a second bottom roller 85, two first bearing seats 86, two second bearing seats 87, two third bearing seats 88, two fourth bearing seats 89, two first pressure adjusting components 90, two second pressure adjusting components 91, two first spacing adjusting components 92, and two second spacing adjusting components 93. The axial ends of the first cutting roller 82 are mounted on the blade holder 81 via two first bearing seats 86. The axial ends of the first bottom roller 84 are mounted on the blade holder 81 via two second bearing seats 87 and are distributed below the first cutting roller 82. The two first pressure adjusting components 90 are mounted on the blade holder 81 and distributed at the axial ends of the first cutting roller 82, used to adjust the distance between the first cutting roller 82 and the first bottom roller 85. The pressure between 4, the two first spacing adjustment components 92 are disposed between the first cutting roller 82 and the first bottom roller 84, and are used to adjust the distance between the first cutting roller 82 and the first bottom roller 84. The two axial ends of the second cutting roller 83 are disposed on the cutter holder 81 through two third bearing seats 88 and are distributed on the transverse side of the second cutting roller 83. The two axial ends of the second bottom roller 85 are disposed on the cutter holder 81 through two fourth bearing seats 89 and are distributed on the lower side of the second cutting roller 83. The two second pressure adjustment components 91 are disposed on the cutter holder 81 and are distributed at the two axial ends of the second cutting roller 83, and are used to adjust the pressure between the second cutting roller 83 and the second bottom roller 85. The two second spacing adjustment components 93 are disposed between the second cutting roller 83 and the second bottom roller 85, and are used to adjust the distance between the second cutting roller 83 and the second bottom roller 85.

[0017] The waistband cutting mechanism 8 enables precise cutting of the diaper waistband. The dual-cutting roller design allows for simultaneous or separate cutting operations to meet different production needs, improving production flexibility and efficiency. Two first pressure adjustment components 90 are located at opposite ends of the first cutting roller 82's axial direction to adjust the pressure between the first cutting roller 82 and the first bottom roller 84. Two second pressure adjustment components 91 are located at opposite ends of the second cutting roller 83's axial direction to adjust the pressure between the second cutting roller 83 and the second bottom roller 85. This independent pressure adjustment design allows for precise control of the pressure between the cutting roller and the bottom roller based on the characteristics of different materials and cutting requirements, ensuring cutting quality and avoiding incomplete cutting or material damage caused by excessive or insufficient pressure. Two first spacing adjustment components 92 are located between the first cutting roller 82 and the first bottom roller 84 to adjust the distance between them; two second spacing adjustment components 93 are located between the second cutting roller 83 and the second bottom roller 85 to adjust the distance between them. By adjusting the spacing, the device can accommodate the cutting of diaper waistbands of different thicknesses and sizes, thus improving its versatility and adaptability.

[0018] Furthermore, both the first pressure regulating component 90 and the second pressure regulating component 91 include a first regulating screw 901 rotatably mounted on the blade holder 81, a support plate 902 rotatably mounted at the lower end of the first regulating screw 901, a through hole on the support plate 902, a bolt 903 passing through the through hole and threadedly connected at its lower end to the first bearing seat 86 or the second bearing seat 88, and a spring 904 sleeved on the bolt 903. The spring 904 is distributed between the support plate 902 and the first bearing seat 86 or the second bearing seat 88, making pressure regulation more convenient and precise. The operator only needs to rotate the first regulating screw 901 to adjust the pressure between the cutter roller and the bottom roller through the linkage of the support plate 902, the bolt 903 and the spring 904. The spring 904 also acts as a buffer, making pressure regulation more stable and ensuring the stability of the cutting process.

[0019] Furthermore, both the first spacing adjustment assembly 92 and the second spacing adjustment assembly 93 include a second adjusting screw 921 rotatably mounted on the cutter holder 81, a wedge block 922 threadedly connected to the second adjusting screw 921, and an inclined surface 923 located on the lower surface of the first bearing seat 86 or the second bearing seat 88 and engaging with the wedge block 922. By rotating the second adjusting screw 921, the wedge block 922 is moved. The engagement of the wedge block 922 with the inclined surface 923 causes the first bearing seat 86 or the second bearing seat 88 to rise or fall, thereby adjusting the spacing between the cutter roller and the bottom roller. This adjustment method is simple in structure, convenient to operate, and can precisely control the spacing to meet different production needs.
