Description

Technical Field

[0001] The invention relates to the field of disposable sanitary products, and in particular to a core production process with skin care particles and diapers and pull-up pants. Background Art

[0002] The core of existing disposable sanitary products is usually formed by only SAP and wood pulp materials, and has only the functions of absorbing water and diverting water. If users wear them for a long time and do not replace urine or feces in time, they are prone to diapering. Especially when adults use pants-type diapers, they need to wear them for a long time. Therefore, the existing core has poor skin care effect.

[0003] Chinese patent application number: 201821700092.4, provides a 3D diversion absorption core, and is connected from top to bottom by an upper covering layer, a composite absorption core layer, and a lower covering layer, and the composite absorption core layer is composed of one or more absorption cores, and a high water-absorbent resin low-density distribution area is arranged at the central position on the lateral width of the composite absorption core layer or / and the central symmetrical position on both sides; a top diversion body and a bottom diversion body corresponding to and facing away from the top diversion body are respectively arranged at the top and bottom of the 3D diversion absorption core corresponding to the high water-absorbent resin low-density distribution area, and a diversion groove circumferentially surrounding the 3D convex body is respectively arranged in the top diversion body and the bottom diversion body, and the depth of the diversion groove is 30% to 40% of the thickness of the 3D diversion absorption core; the 3D convex body is an elliptical 3D convex body, whose width is 1mm to 6mm, and whose height is less than or equal to the depth of the diversion groove, and forms an angle of 55° to 65° with the longitudinal center line of the diversion body. The absorbent core only has the effects of absorption and drainage, but not skin care. The skin care effect is poor, and red buttocks are likely to occur if worn for a long time.

After the urine seeps down, part of the skin care agent adheres to the human body for skin care, and part of the skin care agent adheres to the human body for skin care. The skin care agent will fall onto the core body and continue to provide skin care for the human body.

[0045] S2. Unloading from the first unloading bin 211: the wood pulp unloading box 214 and the SAP unloading box 215 unload and mix the wood pulp and SAP respectively. At the same time, the antibacterial and deodorizing particles 15 are unloaded from the rear end of the first unloading bin 211. The antibacterial and deodorizing particles 15 are unloaded in the first unloading bin 211, and the antibacterial and deodorizing particles 15 are mixed with the polymer material to form a core bottom layer 12. The number of antibacterial and deodorizing particles 15 on the top of the core bottom layer 12 is greater than that of the antibacterial and deodorizing particles 15 at the bottom. The negative pressure on the adsorption holes 222 adsorbs the wood pulp, SAP and the antibacterial and deodorizing particles 15 on the polymer surface layer 10 to form a core bottom layer 12.

[0046] S3. Unloading from the second unloading bin 212: The first particle unloading box 216 first unloads the first skin care particles 13, and the first skin care particles 13 first fall on the core bottom layer 12, and the wood pulp and SAP are then unloaded onto the core bottom layer 12 through another first unloading valve 2140 and a second unloading valve 2150, and the wood pulp and SAP partially wrap and fix the first skin care particles 13, and at least half of the first skin care particles 13 are located in the core top layer 11, and at least a portion of the first skin care particles 13 exceeds the top surface of the core top layer 11 to form the core top layer 11.

[0051] S5. Forming the core body 1: Compounding and wrapping the wrapping layer 17 through the wrapping device 52 to form the core body 1.

[0052] The driving device 51, the wrapping device 52, and the adsorption device 23 are well-known devices and will not be described in detail here.

[0053] The above-mentioned guide groove 16 may also be not set, that is, the adsorption hole 222 is also set in the middle of the second adsorption area 224, so that the middle of the core top layer 11 formed does not have a guide groove 16. The number of the above-mentioned guide grooves 16 can also be two, three or even more, depending on the specific situation.

[0054] The second skin care particles 14 can also be fed to a position other than the guide groove 16, that is, adsorption holes 222 are also provided on both sides of the third adsorption area 225, so that the second skin care particles 14 can evenly fall to the top of the core top layer 11. The second skin care particles 14 can also be fed in other distribution methods, which can be set according to the specific situation.

[0055] The above-mentioned antibacterial and deodorizing particles 15 may also be arranged only in the bottom layer 12 of the core, that is, the antibacterial and deodorizing particles 15 are not discharged at the second discharge bin 212; the above-mentioned antibacterial and deodorizing particles 15 may also be arranged only in the top layer 11 of the core, that is, the antibacterial and deodorizing particles 15 are not discharged at the first discharge bin 211; the above-mentioned antibacterial and deodorizing particles 15 may also not be arranged, that is, the third particle discharge box 218 is not arranged, and it is arranged according to the specific situation.

[0056] The above-mentioned antibacterial and deodorizing particles 15 can also be evenly distributed, that is, the antibacterial and deodorizing particles 15 are evenly discharged from the first discharge bin 211. In this structure, the utilization rate of the antibacterial and deodorizing particles 15 at the bottom is low, which reduces the overall utilization rate of the antibacterial and deodorizing particles 15. The specific setting depends on the situation.

[0057] The first skin care particles 13 are collagen particles, pearl particles or other particles with skin care effects, which are well-known materials and will not be described in detail herein.

[0060] The diameter of the first skin care particles 13 is usually set to 1.5 mm to 5 mm, which is set according to specific circumstances.

[0061] Usually, six-tenths to two-thirds of the first skin care particles 13 are arranged in the top layer 11 of the core, such as two-thirds, three-quarters, three-fifths, etc., depending on the specific situation.

[0062] The wrapping layer 17 is usually provided with ventilation holes, and the first skin care particles 13 can apply the skin care material to the upper material and / or the human body through the ventilation holes to continuously protect the human body.

[0063] The antibacterial deodorant 152 is usually in powder form and is a well-known material, which will not be described in detail here.

[0067] refer to Fig.10 The molding chamber 21 is provided with a glue spraying device 53, which sprays glue on both sides of the core bottom layer 12 in a dot-shaped glue spraying manner to fix the first skin care particles 13 on the core bottom layer 12. This structure, through the double-layer fixation of glue and polymer material, makes it difficult for the first skin care particles 13 to fall off after being squeezed.

[0068] refer to Fig.11 The first skin care particles 13 are provided with a plurality of inwardly recessed notches 130 . When the polymer material is fed, the polymer material can fill the notches 130 , thereby better fixing the first skin care particles 13 .

[0070] The feed ratio of SAP to wood pulp in the second feed bin 212 is greater than 3 and less than 10. The amount of SAP is large, and the top layer 11 of the core has good water absorption and high density. It not only has good water absorption performance, but also is conducive to the fixation of the first skin care particles 13.
