Embodiment Construction

[0032] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0033] refer to Figure 1 to Figure 5 , the present embodiment provides a pull-up pants waist welding process, comprising the following steps:

[0034] (1) Waistline part 1 before manufacture: a plurality of elastic bands 11 and waistline non-woven fabric 12 are conveyed up and down in sequence, glue is sprayed on the waistline non-woven fabric 12, the elastic bands 11 are compounded on the waistline non-woven fabric 12, and passed through the adsorption wheel The mechanism attaches the cotton block 13 longitudinally and intermittently to the waist non-woven fabric 12, the cotton block 13 is attached to one side of the longitudinal centerline of the waist non-woven fabric 12, and the waist non-woven fabric 12 is folded and compounded along the center line to form a front Waist section 1;

[0035] (2) Manufacturing the back waistline part 2: the man...

Abstract

The invention relates to a waistline welding process for pull-ups. The pull-ups comprise a front waistline part, a rear waistline part and an absorption core body, wherein cotton blocks on the front waistline part and the rear waistline part have a buffering effect to prevent the pull-ups from forming red pull marks on the human body; a first welding part and a second welding part are arranged on the front waistline part and the rear waistline part; and the second welding part comprises a plurality of point-shaped welding points. When acting force is large, the welding points can be opened, so that the tension degree of the pull-ups can be controlled, and the pull-ups are comfortable to wear; and in a production process of the pull-ups, a detecting and adjusting mechanism not only has a buffering effect to prevent the pull-ups from being lengthened, but also can adjust the welding time of a welding mechanism, so that the welding and cutting positions of the pull-ups are accurate, and the quality of the pull-ups is improved. The invention relates to the field of disposable sanitary products, and solves the technical problems that the pull-ups are prone to forming the red pull marks on the human body, inaccurate cutting possibly occurs to waistline, and the product quality is affected.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a waist circumference welding process for pull-up trousers. Background technique [0002] When the pull-up pants are manufactured, they are welded by a welding mechanism. When the pull-up pants are worn, the waist is usually close to the human body. When worn for a long time, it is easy to form red stretch marks on the human body, which is uncomfortable to wear, especially when the human body squats down. The elastic of pull-up pants is elongated, and the stretch marks are more obvious, which is easy to cause harm to the human body. During the production of pull-up pants, when the cutter mechanism cuts the pull-up pants into sheets, the cutter mechanism needs to cut on the center line of the pull-up pants welding, because the pull-up pants may slip during transportation, and equipment Vibration or other factors may cause deviation during the conveying of the pull-up p...
