Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of the preparation of sanitary products, and particularly relates to a method for manufacturing a core that can be conveniently replaced. Background Art
[0002] At present, absorbent sanitary products used by women during menstruation sold on the market are mostly sanitary napkins, tampons, etc. The overall structure of the sanitary napkin is flat, and it needs to be fixed on the underwear first when worn. During use, it cannot be completely attached to the body, and the product's position cannot be fixed as the underwear deforms. The structure of the tampon is very inconvenient and uncomfortable during use.
[0003] Therefore, we propose a method for manufacturing a core that can be conveniently replaced to solve the above problems. Summary of the Invention
[0004] The present invention aims to provide a method for manufacturing a core that can be conveniently replaced to overcome or at least partially solve the above problems.
[0005] To achieve the above object, the technical solution of the present invention is specifically implemented as follows:
[0006] The present invention provides a method for manufacturing a core that can be conveniently replaced, including the following steps:
[0007] S1, The wood pulp material is fed into the wood pulp crushing mechanism of the production line at a stable conveying speed by the first unwinding unit, and the wood pulp material is crushed by the wood pulp crushing mechanism to form fiber flocs and enter the fiber accumulation cavity;
[0008] S2, The superabsorbent resin material is fed into the fiber accumulation cavity of the production line at a stable application amount by the superabsorbent resin feeding mechanism, and is uniformly mixed with the fiber flocs formed by the wood pulp material and adsorbed and fallen in the cotton core mold wheel to form a cotton core with a certain density;
[0009] S3, The cotton core is transferred from the cotton core mold wheel to the cotton core forming mechanism, and the required convex effect of the cotton core is formed through the extrusion and forming of the cotton core forming mechanism;
[0010] S4, The fabric is fed into the production line in a flat manner by the second unwinding unit. Using the first tension control unit, the fabric is kept at a stable conveying tension, and is conveyed by the first traction wheel and the first tension swing rod unit. The center position and material tension of the fabric are adjusted by the first deviation correction unit, and hot melt adhesive I is applied to the fabric by a glue gun;
[0011] S5. The bottom water-repellent material is fed into the production line in a flat manner by the third unwinding unit. Using the second tension control unit, the bottom water-repellent material is kept under a stable conveying tension. It is conveyed by the second traction wheel and the second tension swing rod unit. The center position and material tension of the bottom water-repellent material are adjusted by the second deviation rectifying unit. Hot melt adhesive two is applied to the bottom water-repellent material by glue gun two.
[0012] S6. The magic fastener material is fed into the production line in a flat manner by the fourth unwinding unit. Using the third tension control unit, the magic fastener material is kept under a stable conveying tension. It is conveyed by the third traction wheel. The center position and material tension of the magic fastener material are adjusted by the third deviation rectifying unit. Hot melt adhesive three is applied to the magic fastener material by glue gun three. After passing through the magic fastener material forming mechanism, the magic fastener material is attached to the bottom water-repellent material.
[0013] S7. After the fabric, cotton core, bottom water-repellent material, and magic fastener material are all compounded, the whole enters the product forming mechanism through the first negative pressure conveying unit to form the core body. The material waste edges are processed by the waste suction unit. The core body then enters the second negative pressure conveying unit through the product transfer mechanism and is conveyed to the rear end of the equipment.
[0014] As a further solution of the present invention, in the step S2, the high water-absorbing resin material and the wood pulp material are uniformly mixed according to a ratio of 10-20%: 80-90%.
[0015] As a further solution of the present invention, in the step S3, the upper roller of the cotton core forming mechanism is provided with grooves matching the shape required for the cotton core to be formed. The cotton core is sucked into the grooves of the upper roller by the suction effect. The upper roller and the lower roller of the cotton core forming mechanism then form a cotton core with a middle convex effect through extrusion.
[0016] As a further solution of the present invention, in the step S6, the magic fastener material forming mechanism is used to cut the magic fastener material into the required shape.
[0017] As a further solution of the present invention, in the step S7, the product forming mechanism cuts the compounded all materials into the required shape.
[0018] The present invention provides a method for manufacturing a replaceable core body, and the beneficial effects are as follows:
[0019] The product has a good middle convex effect and can be well attached to the user's body. When in use, the middle convex area of the product is first put into the user's body, and then the underwear is put on and attached to the back of the product for fixation, without displacement, enhancing the wearing comfort between the product body and the user. The product can be well embedded in the user's body, can well block and absorb menstrual blood, and prevent the problem of side leakage of the product. It solves the technical problems such as uncomfortable wearing and limited structure of the existing products.
[0020] The mechanization of the equipment is realized, and the manufacturing process is stable, solving the short - board problems of unreasonable conventional product structures and poor wearing experience. BRIEF DESCRIPTION OF THE DRAWINGS
