Problems solved by technology

[0004] The traditional 3D surface layer embossing process is cut into the required width specification embossing after other enterprises or workshops are processed, and then transported to various diaper assembly enterprises or workshops for assembly, so the offline embossed surface layer in There are multiple processing procedures in the process of production and transportation, which increases the risk of increased microbial indicators of raw materials. Excessive microbial indicators directly lead to the appearance of diaper rash during the use of infants and young children

Embodiment

[0030] Embodiment: 1. Forming of the absorbent core: put wood pulp into a pulverizer and pulverize it into fibrous fluff pulp, shape the fluff pulp into the cotton core in the absorbent core layer in the product, and add the polymer material evenly through the polymer adder Into the cotton core of the product, the cotton core is conveyed through the vacuum box device, and the toilet paper roll is unrolled at the same time, the cotton core is attached to the toilet paper and compacted, and the cotton core is wrapped with toilet paper through the vacuum box and folding tool, and passed The pinch roller compacts the wrapped cotton core to form an absorbent core;

[0031] 2. The absorbent core is subjected to grid-pressing treatment;

[0032] 3. Cut the absorbent core into the specified shape according to the product drawing;

[0033] 4. Compounding of the bottom non-woven fabric: adding PE film and non-woven fabric to form the bottom non-woven fabric;

[0034] 5. The 100% natur...

Abstract

The invention discloses an online production process of 3D embossed paper diapers. The process comprises the steps of using a 3D embossing device to make a lower surface layer pass between a first embossing roller and a second embossing roller, then pass between a left roller and the second embossing roller, finally pass between a right roller and the second embossing roller, at the same time making the upper surface layer pass between a left roller and the second embossing roller, and then making the upper surface layer and the lower surface layer pass through between the right roller and the second embossing roller to form a composite surface layer and achieve the 3D embossing of the upper and lower surface layers. All the steps including the final forming of the composite layer are integrated into one time of operation. No hand touch is involved in the middle stages. The online direct composite forming of 3D embossed surface layers with multiple surface layers in production process can be achieved. The risk that in production process multiple times of contact with the surface layers causes increase of microorganism indexes is reduced.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to an online production process of 3D embossed diapers. Background technique [0002] Diapers generally consist of three main parts: a top sheet, an absorbent core, and a bottom nonwoven. The absorbent core layer includes cotton core, polymer material and toilet paper. The bottom non-woven fabric includes PE film and non-woven fabric. The surface layer exists on the top of the diaper and is divided into an upper layer and a lower layer. The upper layer is the inner surface layer of the diaper, and the upper layer Directly in contact with the delicate skin of infants and young children, it receives and transmits liquids. The lower layer is a diversion layer, which has the function of guiding liquids to the core layer and permeating water. Therefore, it is often necessary to perform 3D embossing on the upper and lower layers of the surface layer. 3D On the premise of the existing adv...
