Description

Technical Field

[0001] This invention relates to a diaper elastic band lamination device, belonging to the field of diaper processing equipment. Background Technology

[0002] Disposable diapers, also known as baby diapers, are disposable products used by infants and adults to absorb excrement. Their core function is to quickly absorb urine and lock in moisture to keep the skin dry.

[0003] Elastic bands are elastic materials located in the interlayer of the non-woven fabric substrate of the diaper. They are mainly responsible for fitting the baby's waist and leg circumference to prevent urine leakage.

[0004] The existing diaper elastic band lamination process uses separate bottom nonwoven fabric unwinding units and separate elastic band unwinding units. After the bottom nonwoven fabric unwinding unit outputs the glued bottom nonwoven fabric and the elastic band output from the elastic band unwinding unit, they are initially bonded together and then wound together and guided to the lamination mechanism for lamination. When it is necessary to adjust the elastic band spacing, the adjustment is made through the electronic shaft in the elastic band conveying structure. Since each elastic band is equipped with an electronic shaft, it is impossible to compensate for the sudden change in tension in time during transient conditions such as roll changing and material splicing, which can easily cause the elastic band to stretch and break. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a diaper elastic band lamination device to solve the problems of existing diaper elastic band lamination processes. This device employs separate unwinding units for the bottom nonwoven fabric and elastic bands. After the bottom nonwoven fabric, coated with adhesive, is initially bonded to the elastic bands from the unwinding unit, both are then wound together and guided to the lamination mechanism for lamination. When the elastic band spacing needs adjustment, it is done via an electronic shaft in the elastic band conveying structure. However, because each elastic band is equipped with an electronic shaft, it cannot immediately compensate for sudden tension changes during transient conditions such as roll changes and material splicing, easily leading to elastic band tensile breakage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a diaper elastic band laminating device, comprising a base, with an elastic band laminating module and a positioning plate respectively located at the front and rear of the upper surface of the base; a bottom non-woven fabric conveying module located on the right side of the upper surface of the base; and an outlet module located on the left side of the upper surface of the base. The elastic band laminating module consists of an outer shell and a laminating mechanism inside the shell. The outer shell has openings at its top and sides, which are used for the input of elastic bands, the input of bottom non-woven fabric, and the output of semi-finished products, respectively. The laminating mechanism laminates the bottom non-woven fabric input from the bottom non-woven fabric conveying module with the elastic bands, and finally guides the product to the next diaper via the outlet module. The process includes a composite mechanism comprising a guide plate horizontally fixed to the upper part of the front end face of a positioning plate, a first elastic guide roller horizontally connected to the front end of the guide plate, a bracket fixed to the middle of the front end face of the positioning plate, a second elastic guide roller vertically arranged on the upper end of the bracket, a composite pressure roller assembly arranged at the bottom of the front end face of the positioning plate, a conveying plate horizontally connected to the input end of the composite pressure roller assembly, and a multi-spacing adjustable guide assembly connected to the other end of the conveying plate. A third elastic guide roller is arranged horizontally and longitudinally on the side of the guide plate near the multi-spacing adjustable guide assembly. The multi-spacing adjustable guide assembly is used to guide the bottom nonwoven fabric to the conveying plate and to press the multi-strand elastic bands onto the upper end face of the bottom nonwoven fabric after adjusting the spacing.

[0007] Furthermore, in order to dynamically adjust the elastic band spacing and perform tension compensation during the adjustment process, the multi-spacing adjustable guide assembly includes a guide shell located inside the right side of the outer shell and fixed to the positioning plate, an elastic band outlet, a bottom non-woven fabric outlet, an elastic band inlet, a spacing adjustment seat, a fourth elastic band guide roller, a lifting cylinder, and a bottom non-woven fabric inlet. The elastic band outlet is located at the bottom of the left end face of the guide shell, the bottom non-woven fabric outlet is located on the bottom surface of the guide shell, and the elastic band inlet is located on the top surface of the guide shell. The spacing adjustment seat is movably located inside the guide shell. The fourth elastic band guide roller is horizontally and longitudinally located between the spacing adjustment seat and the elastic band inlet. The lifting cylinder is located on the top surface of the inner wall of the guide shell, with its output end facing downwards and connected to the spacing adjustment seat to drive the spacing adjustment seat to move up and down. The bottom non-woven fabric inlet is located at the bottom of the right end face of the guide shell and communicates with the bottom non-woven fabric outlet.

[0008] Furthermore, in order to sort out the elastic bands during the introduction process, a number of elastic band isolation grooves are arranged sequentially from front to back on the inner wall of the elastic band inlet.

[0009] Furthermore, in order to guide the bottom nonwoven fabric onto the conveyor plate, the outlet of the bottom nonwoven fabric is connected to the conveyor plate.

[0010] Furthermore, in order to adjust the spacing of multiple rubber strands at once, the spacing adjustment seat includes a seat body, a rotating groove, an elastic band guide channel, a spacing orientation pressing component, an adjusting motor, a guide port, and a fifth elastic band guide roller. The rotating groove is located at the bottom of the seat body, the elastic band guide channel is vertically located on the right side of the seat body, the spacing orientation pressing component is horizontally and longitudinally rotatably located in the rotating groove, the adjusting motor is located on the outer wall of the seat body, and the output end of the adjusting motor is horizontally and longitudinally connected to the center of the front end face of the spacing orientation pressing component. One end of the guide port communicates with the rotating groove, and the other end communicates with the bottom of the elastic band guide channel. The fifth elastic band guide roller is horizontally and longitudinally located in the guide port.

[0011] Furthermore, in order to improve the accuracy of the elastic band spacing adjustment, the spacing orientation pressing component is specifically an equilateral prism structure, and each edge has several elastic band positioning grooves arranged side by side. The front center of the equilateral prism structure has an interface that is compatible with the output end of the adjustment motor.

[0012] Furthermore, in order to perform the coating and conveying of the bottom nonwoven fabric, the bottom nonwoven fabric conveying module includes a winding drum for winding the bottom nonwoven fabric and a glue roller for coating the upper surface of the bottom nonwoven fabric. The output module includes a semi-finished product conveying roller for guiding the semi-finished product out.

[0013] Furthermore, in order to perform the lamination of the surface nonwoven fabric and the traction and cutting of the semi-finished product, the system also includes a surface nonwoven fabric conveying module, a surface nonwoven fabric lamination module, a traction module, and a cutting module located at the output end of the output module.

[0014] The beneficial effects of this invention are as follows: the laminating mechanism in the diaper elastic band laminating equipment positions and adheres the input elastic band to the bottom non-woven fabric, and then directly performs the laminating work. Compared with the prior art, which requires the elastic band and the bottom non-woven fabric to go through bonding, winding, and re-introduction, this effectively improves the efficiency of the elastic band laminating work. In addition, the laminating mechanism is equipped with a multi-spacing adjustable guide component, which can dynamically adjust the spacing of the multi-strand elastic bands in a tension-compensated manner, which helps to prevent the elastic band from stretching and breaking under transient conditions such as roll changing and material splicing.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This invention provides a technical solution for a diaper elastic band composite device: its structure includes a base 1, with an elastic band composite module 11 and a positioning plate 12 respectively located at the front and rear of the upper surface of the base 1. A bottom non-woven fabric conveying module 13 is located on the right side of the upper surface of the base 1, and an output module 14 is located on the left side of the upper surface of the base 1. The elastic band composite module 11 consists of an outer shell and a composite mechanism inside the outer shell. The top and sides of the outer shell have openings, which are used for the input of elastic bands, the input of bottom non-woven fabric, and the output of semi-finished products, respectively. The composite mechanism composites the bottom non-woven fabric input from the bottom non-woven fabric conveying module 13 with the elastic bands, and finally guides it to the next process through the output module 14. The composite mechanism includes a guide horizontally fixed to the upper part of the front end face of the positioning plate 12. The guide plate 111, a first elastic guide roller 112 horizontally connected to the front end of the guide plate 111, a bracket 113 fixed to the middle of the front end face of the positioning plate 12, a second elastic guide roller 114 vertically arranged on the upper end of the bracket 113, a composite pressure roller assembly 115 arranged at the bottom of the front end face of the positioning plate 12, a conveying plate 116 horizontally connected to the input end of the composite pressure roller assembly 115, and a multi-spacing adjustable guide assembly 117 connected to the other end of the conveying plate 116. A third elastic guide roller 1111 is arranged horizontally and longitudinally on the side of the guide plate 111 near the multi-spacing adjustable guide assembly 117. The multi-spacing adjustable guide assembly 117 is used to guide the bottom nonwoven fabric to the conveying plate 116 and to press the multi-strand elastic bands onto the upper end face of the bottom nonwoven fabric after adjusting the spacing.

[0019] Among them, the composite pressure roller assembly 115 is the prior art, which consists of a composite support, a drive roller and a pressure roller rotatably disposed in the composite support, and a motor that drives the drive roller to rotate. The elastic band and the bottom non-woven fabric in the initial bonding state are extruded and composited between the drive roller and the pressure roller.

[0020] The laminating mechanism in the diaper elastic band laminating equipment positions and adheres the input elastic band to the bottom non-woven fabric, and then directly performs the laminating work. Compared with the existing technology, which requires the elastic band and the bottom non-woven fabric to go through bonding, winding, and re-introduction, this effectively improves the efficiency of the elastic band laminating work. In addition, the laminating mechanism is equipped with a multi-spacing adjustable guide component 117, which can dynamically adjust the spacing of the multi-strand elastic bands in a tension-compensated manner, which helps to prevent the elastic band from stretching and breaking under transient conditions such as roll changing and material splicing.

[0021] To dynamically adjust the elastic band spacing and compensate for tension during adjustment, the multi-spacing adjustable guide assembly 117 includes a guide housing 1171 located inside the right side of the housing and fixed to the positioning plate 12, an elastic band outlet 1172, a bottom non-woven fabric outlet 1173, an elastic band inlet 1174, a spacing adjustment seat 1175, a fourth elastic band guide roller 1176, a lifting cylinder 1177, and a bottom non-woven fabric inlet 1178. The elastic band outlet 1172 is located at the bottom of the left end face of the guide housing 1171, and the bottom non-woven fabric outlet 1173 is located on the bottom surface of the guide housing 1171. The elastic band inlet 1174 is located on the top surface of the guide housing 1171. The spacing adjustment seat 1175 is movably located inside the guide housing 1171. The fourth elastic band guide roller 1176 is horizontally and longitudinally located between the spacing adjustment seat 1175 and the elastic band inlet 1174. The lifting cylinder 1177 is located on the top surface of the inner wall of the guide housing 1171. The output end of the lifting cylinder 1177 faces downward and is connected to the spacing adjustment seat 1175 to drive the spacing adjustment seat 1175 to move up and down. The bottom nonwoven fabric inlet 1178 is located at the bottom of the right end face of the guide housing 1171 and communicates with the bottom nonwoven fabric outlet 1173.

[0022] The working principle of the multi-spacing adjustable guide assembly 117 is as follows: multiple elastic bands enter the guide housing 1171 through the elastic band inlet 1174. Under the positioning of the fourth elastic band guide roller 1176, they pass under the spacing adjustment seat 1175. Under the spacing positioning and pressing of the spacing adjustment seat 1175, they are finally output through the elastic band outlet 1172. The bottom non-woven fabric enters through the bottom non-woven fabric inlet 1178 and is horizontally output to the conveyor plate 116 through the bottom non-woven fabric outlet 1173, where it is bonded to the elastic bands output from the elastic band outlet 1172. When the spacing adjustment seat 1175 adjusts the elastic band spacing, the lifting cylinder 1177 drives the spacing adjustment seat 1175 to move up or down to compensate for tension.

[0023] In order to sort out the elastic bands during the introduction process, a number of elastic band isolation grooves 11741 are arranged on the inner wall of the elastic band inlet 1174 from front to back.

[0024] In order to guide the bottom nonwoven fabric onto the conveyor plate 116, the bottom nonwoven fabric outlet 1173 is connected to the conveyor plate 116.

[0025] To adjust the spacing of multiple rubber strands at once, the spacing adjustment seat 1175 includes a seat body 11751, a rotating groove 11752, an elastic band guide channel 11753, a spacing orientation pressing component 11754, an adjustment motor 11755, a guide port 11756, and a fifth elastic band guide roller 11757. The rotating groove 11752 is located at the bottom of the seat body 11751, and the elastic band guide channel 11753 is vertically located on the right side of the seat body 11751. The spacing orientation pressing component 11754... The pressing component 11754 is horizontally and longitudinally rotatably disposed within the rotating groove 11752. The adjusting motor 11755 is disposed on the outer wall of the base 11751. The output end of the adjusting motor 11755 is horizontally and longitudinally connected to the center of the front end face of the spacing-oriented pressing component 11754. One end of the guide port 11756 communicates with the rotating groove 11752, and the other end communicates with the bottom of the elastic band guide channel 11753. The fifth elastic band guide roller 11757 is horizontally and longitudinally disposed within the guide port 11756.

[0026] like Figure 5 As shown, in order to improve the accuracy of elastic band spacing adjustment, the spacing orientation pressing member 11754 is specifically an equilateral triangular prism structure, and each edge has several elastic band positioning grooves 117541 arranged side by side. The front center of the equilateral prism structure has an interface adapted to the output end of the adjusting motor 11755. However, the invention is not limited to this. The spacing orientation pressing member 11754 can also be an equilateral polyprism structure such as an equilateral quadrangular prism, an equilateral pentagonal prism, or an equilateral hexagonal prism. The more edges there are, the more adjustable elastic band spacing dimensions there are.

[0027] The working principle of the spacing adjustment seat 1175 is as follows: multiple elastic bands first pass through the elastic band guide channel 11753, and then, under the guidance of the fifth elastic band guide roller 11757 in the guide port 11756, they contact the directional pressing member 11754. Each elastic band corresponds to an elastic band positioning groove 117541. The spacing of the elastic band positioning groove 117541 on each edge is different. The edge at the bottom position is in the working state. During adjustment, the adjustment motor 11755 drives the directional pressing member 11754 to rotate, adjusting the position of the edge. During the adjustment process, under the positioning of the inclined inner wall of the elastic band positioning groove 117541, the elastic band will be squeezed into the elastic band positioning groove 117541 of the downward rotating edge. Since the spacing of the elastic band positioning groove 117541 is different, the spacing of the multiple elastic bands will also be adjusted accordingly. This adjustment action will not affect the conveying and traction of the elastic band, that is, dynamic adjustment is achieved.

[0028] In order to perform the coating and conveying of the bottom nonwoven fabric, the bottom nonwoven fabric conveying module 13 includes a winding drum for winding the bottom nonwoven fabric and a glue roller for coating the upper surface of the bottom nonwoven fabric. The output module 14 includes a semi-finished product conveying roller for guiding the semi-finished product out.

[0029] In order to perform the lamination of the surface nonwoven fabric and the traction and cutting of the semi-finished products, the system also includes a surface nonwoven fabric conveying module, a surface nonwoven fabric lamination module, a traction module and a cutting module, which are set at the output end of the output module 14.

[0030] The working principle of the diaper elastic band laminating equipment is as follows: the elastic band conveying equipment outside the equipment introduces multiple strands of elastic bands through the opening above the elastic band laminating module 11, and the bottom non-woven fabric conveying module 13 introduces the bottom non-woven fabric through the opening on the right side of the elastic band laminating module 11. The multiple strands of elastic bands pass sequentially through the first elastic band guide roller 112, the second elastic band guide roller 114, and the third elastic band guide roller 1111, and then are introduced into the multi-spacing adjustable guide component 117. Under the spacing positioning and downward pressure of the multi-spacing adjustable guide component 117, they are initially bonded to the adhesive bottom non-woven fabric passing under the multi-spacing adjustable guide component 117. The initially bonded elastic bands and bottom non-woven fabric are positioned by the conveying plate 116 and enter the laminating pressure roller component 115 for lamination. Then, the laminated semi-finished product is guided by the export module 14 to the surface non-woven fabric conveying module and the surface non-woven fabric laminating module for the lamination of the surface non-woven fabric. Finally, it is cut by the cutting module. All the above material movements are traction-controlled by the traction module.
