Description

Technical Field

[0001] The present invention relates to the technical field of composite protection structures of diapers, and more specifically, to a three-dimensional side protection structure of a diaper and a composite device and a composite method thereof. Background Art

[0002] Diapers are disposable sanitary products designed for infants and incontinent adults to absorb and retain urine, feces and other excretions. Modern diapers usually have three-dimensional leak-proof edges and elastic leg cuffs to effectively prevent side leakage.

[0003] Usually, non-woven fabric and rubber band are required to be compounded to produce a three-dimensional side protection structure. When producing the three-dimensional side protection structure, since the three-dimensional side protection structure needs to be erected when in use, the internal rubber band needs to be installed in an arc shape, and the existing rubber band is sprayed with glue on the surface before installation. When limiting, the fixing glue on the surface of the rubber band is easily taken away by the limiting roller, which can easily lead to the loose installation of the rubber band, causing the internal rubber band to be offset during use, and when the viscosity of the fixing glue is too high, the rubber band will also stick to the surface of the limiting roller, resulting in the rubber band being unable to be installed on the non-woven surface.

[0004] In order to ensure the fit of the diapers during production, some diapers will adjust the elastic band spacing inside the three-dimensional protective structure to shorten the distance between the two elastic bands. In addition, in order to ensure the comfort of the diapers during production, some diapers will also adjust the elastic band spacing inside the three-dimensional protective structure to lengthen the distance between the two elastic bands. However, the existing three-dimensional protective structure installation equipment cannot automatically adjust the elastic band spacing inside the three-dimensional protective structure, and manual adjustment is required, resulting in reduced production efficiency of diapers of two different specifications.

[0036] Specifically, the extension and retraction of the output end of the dual-axis cylinder 813 is used to control the sliding of the slider 814, thereby controlling the movement of the limit assembly 83 and the material pulling assembly 82, and then adjusting the installation spacing of the two rubber bands 123.

[0037] See also Figure 5 The material pulling assembly 82 includes a guide slider 821 fixedly connected to the lower side of the slider 814 , a slide groove 822 is provided inside the guide slider 821 , and a material pulling module 823 is provided on one side of the guide slider 821 .

[0038] Specifically, the guide slide block 821 is used to guide the material pulling module 823 to slide.

[0039] See also Figure 6The material pulling module 823 includes an electric slider 8237 slidably connected to the inside of the slide groove 822, one side of the electric slider 8237 is fixedly connected to the second hydraulic cylinder 8238, the output end of the second hydraulic cylinder 8238 is fixedly connected to the second electric clamp 8239, one side of the second electric clamp 8239 is provided with a limit plate 8235 and the limit plate 8235 is fixedly connected to the guide slider 821, the upper side of the limit plate 8235 is provided with two limit baffles, and one side of the limit plate 8235 is provided with a first hydraulic Cylinder 8233 and the first hydraulic cylinder 8233 is fixedly connected to the guide sliding block 821, the output end of the first hydraulic cylinder 8233 is fixedly connected to the first electric clamp 8234, the upper side of the first electric clamp 8234 is provided with a fifth support plate 8231 and the fifth support plate 8231 is fixedly connected to the guide sliding block 821, the upper side of the fifth support plate 8231 is fixedly connected to the second cylinder 8236, the output end of the second cylinder 8236 passes through the fifth support plate 8231 and is fixedly connected to the cutter 8232.

[0040] Specifically, the first electric clamp 8234 and the second electric clamp 8239 are both used to clamp one end of the rubber band 123. When clamping, a section of the rubber band 123 is left between the clamping ends of the first electric clamp 8234 and the second electric clamp 8239. The extension of the output end of the second cylinder 8236 is used to control the cutter 8232 to move downward, thereby cutting the rubber band 123. The extension and retraction of the output end of the first hydraulic cylinder 8233 controls the movement of the first electric clamp 8234, and the extension and retraction of the output end of the second hydraulic cylinder 8238 controls the movement of the second electric clamp 8239. The electric slider 8237 is an internal motor that controls the roller to rotate, and the roller rolls inside the slide groove 822, thereby driving the electric slider 8237 to move along the slide groove 822, thereby controlling the second electric clamp 8239 to move along the slide groove 822.

[0041] In the initial state, the first electric clamp 8234 and the second electric clamp 8239 both clamp one end of the rubber band 123, and non-woven fabric is placed under the rubber band 123. Before adjusting the shape of the rubber band 123, the rubber band unwinding roller 3 unwinds the rubber band 123, and the first electric clamp 8234 releases the rubber band 123. The electric slider 8237 controls the second electric clamp 8239 to move along the slide groove 822, so as to pull one end of the rubber band 123 from the initial end of the slide groove 822 to the end of the slide groove 822. At this time, the output ends of the first hydraulic cylinder 8233 and the second hydraulic cylinder 8238 extend to control the movement of the rubber band 123 so that it is stuck at the lower end of the limiting roller 838. When the limiting component 83 pulls the rubber band 123 3 Adjust the angle to spray glue, and fix it above the non-woven fabric sprayed with fixed glue, the extension control cutter 8232 at the output end of the second cylinder 8236 moves downward to cut the rubber band 123, the second electric clamp 8239 stops clamping the rubber band 123 and returns to its position, and clamps one end of the rubber band 123 above the limit plate 8235, the first electric clamp 8234 stops clamping the rubber band 123, the rubber band unwinding roller 3 unwinds the rubber band 123 again, the second electric clamp 8239 drives the clamped rubber band 123 to move again, the output end of the double-axis cylinder 813 retracts, and the spacing between the two rubber bands 123 is adjusted, so that the second rubber band 123 is fixed above the non-woven fabric.

[0042] When a fitted diaper is required, after the first elastic band 123 is fixed, the output end of the double-axis cylinder 813 is retracted by one third, so that the distance between the two elastic bands 123 becomes shorter, thereby enhancing the elasticity of the two elastic bands 123 .

[0043] When it is necessary to produce a comfortable diaper, after the first elastic band 123 is fixed, the output end of the double-axis cylinder 813 is retracted by two-thirds, so that the distance between the two elastic bands 123 becomes longer and the elasticity of the two elastic bands 123 is weakened.

[0044] The elastic band 123 is cut through the pulling module 823, and the two ends of the elastic band 123 are fixed. The limiting component 83 adjusts the bending curvature of the elastic band 123, and sprays glue on the elastic band while adjusting, and presses it above the non-woven fabric sprayed with fixing glue. The output end of the double-axis cylinder 813 extends or retracts to control the sliding block 814 to slide, thereby controlling the movement of the limiting component 83 and the pulling component 82, and then adjusting the installation spacing of the two elastic bands 123, controlling the elasticity of the three-dimensional protective structure of the diaper, thereby producing comfortable diapers and fitting diapers, and achieving the effect of automatically adjusting the spacing of the elastic bands 123 inside the three-dimensional protective structure according to actual needs.

[0045] In the second embodiment, when producing the side three-dimensional protective structure, since the side three-dimensional protective structure needs to be erected when in use, the internal elastic band 123 needs to be installed in an arc shape, and the existing elastic band 123 is sprayed with glue on the surface before installation. When limiting, the fixing glue on the surface of the elastic band 123 is easily taken away by the limiting roller 838, which can easily lead to the elastic band 123 being installed loosely, causing the internal elastic band 123 to be displaced when in use, and when the viscosity of the fixing glue is too high, the elastic band 123 will also stick to the surface of the limiting roller 838, thereby causing the elastic band 123 to be unable to be installed on the non-woven fabric surface.

[0046] See also Figure 7 The limiting assembly 83 includes a guide slide 832 fixedly connected to one side of the slider 814, an arc-shaped limiting groove 839 is provided inside the guide slide 832, a third cylinder 831 is fixedly connected to the upper side of the guide slide 832, a U-shaped plate 833 is fixedly connected to the output end of the third cylinder 831, a connecting rod 834 is hinged inside the U-shaped plate 833, a sliding column 835 is fixedly connected to the other end of the connecting rod 834, and the sliding column 835 is slidably connected to the arc-shaped limiting groove 839, a second glue gun 836 is fixedly connected inside the sliding column 835, the second glue gun 836 is connected to the second storage tank 811 pipeline, and an electric push rod 837 and a limiting roller 838 are respectively provided on both sides of the second glue gun 836, the output end of the electric push rod 837 is fixedly connected to a pressure plate, and the lower side of the limiting roller 838 is I-shaped.

[0047] Specifically, the extension and retraction of the output end of the third cylinder 831 is used to control the sliding column 835 to move along the arc-shaped limit groove 839, thereby controlling the second glue gun 836 to move along the arc-shaped limit groove 839, and the limit roller 838 slides along the arc-shaped limit groove 839, thereby adjusting the angle of the rubber band 123. The second glue gun 836 is used to spray fixing glue on the surface of the rubber band 123, and the extension of the output end of the electric push rod 837 is used to control the pressure plate to press the glue-sprayed rubber band 123 above the non-woven fabric sprayed fixing glue as soon as possible.

[0048] When it is necessary to adjust the angle of the non-woven fabric for spraying glue and fix it above the non-woven fabric spray-fixing glue, the output end of the third cylinder 831 extends the control slide column 835 to move along the arc-shaped limit groove 839. While the limit roller 838 moves, the rubber band 123 is squeezed into an arc angle by extrusion. After the rubber band 123 is squeezed into the arc angle, the second glue gun 836 sprays glue on the rubber band 123 at the arc angle at the same time, and the output end of the electric push rod 837 extends to control the pressing plate to press the glue-sprayed rubber band 123 above the non-woven fabric spray-fixing glue as soon as possible, thereby adjusting the rubber band 123 to the shape of the arc-shaped limit groove 839 and pressing it above the non-woven fabric spray-fixing glue.

[0050] Specifically, the winding roller 4 begins to wind the non-woven fabric with the elastic band 123 installed, and the non-woven fabric passes through the first folding roller 95, the second folding roller 94 and the third folding roller 96 in sequence. One side of the non-woven fabric is first folded forty-five degrees, then folded ninety degrees, and finally folded one hundred and thirty-five degrees, so that one side of the non-woven fabric is evenly folded in sequence. After the folding is completed, the output end of the first cylinder 91 extends out to control the U-shaped pressing block 93 to press the folded side of the non-woven fabric against the top of the elastic band 123, thereby completing the pressing.

[0051] The limiting roller 838 is controlled by the third cylinder 831 to move along the arc-shaped limiting groove 839. The limiting roller 838 squeezes the rubber band 123 to make it squeezed into an arc angle. After squeezing, the rubber band 123 is sprayed with fixing glue. While spraying the fixing glue, the electric push rod 837 controls the pressing plate to press the rubber band 123 on the non-woven fabric sprayed with fixing glue. After the rubber band 123 is adjusted in shape, it is immediately sprayed and pressed, which effectively prevents the fixing glue on the surface of the rubber band 123 from being easily taken away by the limiting roller 838, thereby achieving the effect of high adhesive firmness of the rubber band 123.

[0052] Embodiment 3, a method for compounding a three-dimensional side protective structure of a diaper, according to the compounding device of the three-dimensional side protective structure of a diaper described above, comprises the following steps: S1: The non-woven fabric unwinding roller 2 unwinds the non-woven fabric, and after being cut by the cutting assembly 5, the non-woven fabric spraying mechanism 6 sprays the fixing glue on one side of the two non-woven fabrics, and the two non-woven fabrics are transferred to the upper side of the elastic spraying mechanism 8.

[0053] S2: The rubber unwinding roller 3 unwinds the rubber, the pulling component 82 cuts the rubber and fixes both ends, the limiting component 83 adjusts the rubber into an arc, sprays fixing glue on the surface of the rubber while adjusting it into an arc, and presses it above the non-woven fabric sprayed with fixing glue.

[0054] The more specific steps of S2 are as follows: S21: in the initial state, the first electric clamp 8234 and the second electric clamp 8239 both clamp one end of the rubber band 123, and non-woven fabric is placed under the rubber band 123. Before adjusting the shape of the rubber band 123, the rubber band unwinding roller 3 unwinds the rubber band, and the first electric clamp 8234 releases the rubber band 123. The electric slider 8237 controls the second electric clamp 8239 to move along the slide groove 822, thereby pulling one end of the rubber band 123 from the initial end of the slide groove 822 to the end of the slide groove 822. At this time, the output ends of the first hydraulic cylinder 8233 and the second hydraulic cylinder 8238 extend to control the movement of the rubber band 123 so that it is stuck at the lower end of the limiting roller 838. S22: When the non-woven fabric needs to be adjusted to a good angle for spraying glue and fixed above the non-woven fabric sprayed fixing glue, the output end of the third cylinder 831 extends the control slide column 835 to move along the arc-shaped limit groove 839. While the limit roller 838 moves, the rubber band is squeezed into an arc angle by extrusion. After the rubber band 123 is squeezed into an arc angle, the second glue gun 836 sprays glue on the rubber band at the arc angle at the same time, and the output end of the electric push rod 837 extends to control the pressing plate to press the glue-sprayed rubber band 123 above the non-woven fabric sprayed fixing glue for the first time, thereby adjusting the rubber band to the shape of the arc-shaped limit groove 839 and pressing it above the non-woven fabric sprayed fixing glue.

[0055] S23: The extension control cutter 8232 at the output end of the second cylinder 8236 moves downward to cut the rubber band 123, the second electric clamp 8239 stops clamping the rubber band 123 and returns to its position, and clamps one end of the rubber band 123 above the limit plate 8235, the first electric clamp 8234 stops clamping the rubber band 123, the rubber band unwinding roller 3 unwinds the rubber band again, the second electric clamp 8239 drives the clamped rubber band 123 to move again, the output end of the double-axis cylinder 813 retracts, and the spacing between the two rubber bands 123 is adjusted, so that the second rubber band is fixed above the non-woven fabric.

[0056] S24: When a fitted diaper needs to be produced, after the first elastic band 123 is fixed, the output end of the double-axis cylinder 813 is retracted by one third, so that the distance between the two elastic bands becomes shorter, thereby enhancing the elasticity of the two elastic bands 123.

[0057] S25: When it is necessary to produce a comfortable diaper, after the first elastic band 123 is fixed, the output end of the double-axis cylinder 813 is retracted by two-thirds, so that the distance between the two elastic bands becomes longer, and the elasticity of the two elastic bands 123 is weakened.

[0058] S3: The winding roller 4 continues to wind up the non-woven fabric with the rubber band attached. When the non-woven fabric passes through the folding mechanism 9, the folding mechanism 9 adjusts the bending angle of one side of the non-woven fabric in sequence, and each adjustment angle is forty-five degrees, thereby folding one side of the non-woven fabric.

[0059] The more specific steps of S3 are, S31: the winding roller 4 starts to wind the non-woven fabric with the elastic band 123, and the non-woven fabric passes through the first folding roller 95, the second folding roller 94 and the third folding roller 96 in sequence, and one side of the non-woven fabric is first folded forty-five degrees, then folded ninety degrees, and finally folded one hundred and thirty-five degrees, so that one side of the non-woven fabric is evenly folded in sequence.

[0060] S4: When one side of the non-woven fabric is completely folded over and pressed on the elastic band, the folding mechanism 9 presses the folded side of the non-woven fabric tightly, and the winding roller 4 rolls up the manufactured side three-dimensional protective structure.

[0061] The more specific step of S4 is, S41: after the folding is completed, the output end of the first cylinder 91 extends to control the U-shaped pressing block 93 to press the folded side of the non-woven fabric tightly on the top of the elastic band 123, thereby completing the pressing.

[0062] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
