Embodiment Construction

[0028] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiments of the invention are:

[0030] A method for producing a pant-type absorbent article, the pant-type absorbent article is a pant-type sanitary napkin, comprising the following steps:

[0031] 1) Prepare a liquid-permeable surface layer;

[0032] 2) Prepare the absorbent core layer;

[0033] 3) Prepare a liquid-impermeable bottom layer;

[0034] 4) The liquid-permeable surface layer, absorbent core layer, and liquid-impermeable bottom layer are sequentially stacked and fixed into one body;

[0035] 5) Divide the product in step 4 into individual products, define that the product has a transverse direction along its own length direction and a longitudinal direction along its own width direction, and change the single product from horizontal conveying to longitudinal conveying;

[0036] 6) Prepare the clothing layer, and fix the pro...

Abstract

The present invention relates to the field of sanitary products, in particular to a production method of trouser-type absorbent products, which mainly solves the problems of seam offset, missing seam, incomplete seam and undetectable seam failure in the production line of trouser-type absorbent products in the prior art , resulting in the problem of bad products flowing into the market, including welding the longitudinal ends of the clothing layer to form a stitched area, and performing online inspection on the stitched area, and rejecting unqualified products in the subsequent process; in the ultrasonic welding station There is a linear lighting device between the cutting station and the slitting station, and a linear camera is installed on the other side of the linear photo device; the host controller or an independently set controller obtains the production speed information of the host, and determines the slitting line of each stitching area as the S baseline, compare the stitched area captured by the line camera with the S baseline, and determine whether the deviation between the sealing edge of the stitched area and the S baseline is ≤ 3mm, and if it exceeds, reject the defective product in the subsequent process.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a production method of pants-type absorbent products. Background technique [0002] Pants-style absorbent products include pant-style sanitary napkins, trouser-style diapers and other pant-style products with a 360-degree elastic waist design. The structure of pants-type absorbent articles is generally: from top to bottom, it includes a liquid-permeable surface layer, an absorbent core layer, a liquid-impermeable bottom layer and a clothing layer. The absorbent core layer is used to absorb and retain human excretions. , the liquid-permeable surface layer is used to provide a comfortable and dry feeling when in contact with the body, while allowing liquid to pass freely into the lower absorbent core layer, and the liquid-impermeable bottom layer is composed of a breathable impermeable film and a hydrophobic non-woven fabric It is used to keep the absorbent liquid in the absorbent...
