A pull-on diaper with uniform force on waist and processing equipment thereof

Abstract

The present invention provides a pull-on diaper with uniform force on the waist, belonging to the technical field of disposable sanitary products. The structure of the pull-on diaper includes an outer layer, a waist assembly, an inner layer and an absorbent core. The waist assembly includes a waist folded inner layer and a waist folded outer layer. A plurality of force strips are arranged vertically at intervals between the waist folded inner layer and the waist folded outer layer. The vertical spacing of the force strips on the waist assembly is small and densely designed, so that the waist assembly is divided into a plurality of small expansion gaps under the lateral expansion and contraction of the elastic strips. When a child moves and pulls, the various expansion gaps will be expanded and contracted by the pulling force respectively, thereby improving the uniform force performance of the waist, avoiding the existing uneven force and large-area expansion and contraction, resulting in one side of the trousers waist being higher and the other side being lower, causing the trousers waist to be repeatedly pulled high and low and the pull-on diaper to fall down continuously. The use is more convenient.

Description

Technical Field

[0001] The invention relates to a pull-on diaper with uniform force on the waist and processing equipment thereof, belonging to the technical field of disposable sanitary products. Background Art

[0002] Most of the pull-on diapers have a front waistline portion corresponding to the front waist of the human body, a front crotch portion corresponding to the front hip of the human body, a rear waistline portion corresponding to the back waist of the human body and a rear crotch portion corresponding to the back hip of the human body. The front waistline portion is integrally connected with the front crotch portion, and the rear waistline portion is integrally connected with the rear crotch portion. The front waistline portion and the rear waistline portion can be arbitrarily separated and connected together by Velcro, which is convenient for mothers to change diapers for their babies.

[0003] During the use of pull-up diapers, I found that the elastic waist parts of the existing pull-up diapers would be unevenly stressed as the child pulled them, so that one side of the waist would be higher than the other. The pull-up diapers would keep falling down due to repeated pulling, and eventually side leakage would occur. Therefore, parents need to frequently lift and adjust the pull-up diapers, which is troublesome to use. In this regard, the present invention proposes a pull-up diaper with uniform waist stress and corresponding processing equipment. Summary of the invention

A cutting knife edge 5135 is longitudinally arranged on the left side of the top surface of the suction plate 5131, and the lower end of the air suction box 5133 is connected to a vacuum pump 514 through an air suction hose.

[0030] The wire pulling mechanism 52 includes a wire pulling slide rail 521, a wire clamping mechanism 522 movably arranged on the rail body of the wire pulling slide rail 521, and a wire pulling moving mechanism 523.

The pneumatic clamp 5232 is connected to a first suction hose, and the other end of the first suction hose is connected to A first vacuum pump 5233, the wire pressing and cutting mechanism 53 includes a wire pressing mechanism bracket 531, a second telescoping device 532 vertically arranged on the wire pressing mechanism bracket 531, a connecting plate 533 connected to the lower end of the second telescoping device 532, a plurality of stabilizing rods 534 arranged on the left and right sides of the top surface of the connecting plate 533, and the other end of each of the stabilizing rods 534 passes through the wire pressing mechanism bracket 531, a wire pressing plate 535 is arranged on the bottom surface of the connecting plate 533, and a cutter 536 is arranged on the left side of the wire pressing plate 535, and the wire arranging assembly 54 includes a wire arranging frame 541, a wire arranging tube horizontal frame 542 arranged on the top surface of the wire arranging frame 541, and a plurality of wire threading tubes 543 nested in the wire arranging tube horizontal frame 542 at intervals.

[0031] The working principle is that through the dense design of the small spacing of each stress strip 23, under the lateral elastic expansion and contraction action of each elastic strip 24, the waist folding inner layer 21 and the waist folding outer layer 22 are divided into a plurality of smaller expansion and contraction gaps after being folded, so that the stress on the waist is more uniform.

[0032] Another processing method of the stress strip is that the staff first places the waist folded inner layer 21 and the waist folded outer layer 22 flat on the top surface of the suction plate 5131. At this time, one side of the waist folded inner layer 21 is sprayed with glue in advance, and then the vacuum pump 514 sucks the waist material. Then, each slider 5132 transports the suction plate 5131 backward to the bottom of the pressing and cutting mechanism 53. At this time, the cutter 536 is vertically aligned with the cutter edge 5135, and then pulls The wire moving mechanism 523 moves to the left on the wire pulling slide rail 521, and then the pneumatic clamp 5232 clamps the wire end on the right side of the wire clamping mechanism 522 through the first vacuum pump 5233, and first the first retractor 5222 retracts to separate the upper wire pressing plate 5223 from the lower wire pressing plate 5224, and then the wire pulling moving mechanism 523 moves to the right to return to its original position, pulling each stress bar 23 through the top surface of the waist folded inner layer 21. In this process, the wire arrangement assembly 54 acts The first retractor 5222 extends out to press the upper wire pressing plate 5223 and the lower wire pressing plate 5224 together to press and fix the left side of each stress bar 23. The second retractor 532 extends out through the connecting plate 533 to drive the wire pressing plate 535 and the cutter 536 to descend synchronously. At this time, the wire pressing plate 535 presses each stress bar 23 downward to make each stress bar 23 adhere to the glue on the waist folding inner layer 21. The cooperation of the cutter 536 and the cutter blade 5135 cuts the left side of each stress bar 23. The wire pressing and cutting mechanism 53 rises back to its original position, the pneumatic clamp 5232 is released, and then each slider 5132 drives the suction plate 5131 to move forward. Finally, the material is taken out and replaced again to complete the one-time uniform spacing arrangement processing of each stress bar 23.
