What is a sanitary napkin manufacturing machine?

A sanitary napkin manufacturing machine is specialized machinery and equipment used for producing female sanitary napkins. These machines are typically highly automated and designed for large-scale production of sanitary napkins to meet market demands.

Sanitary napkin manufacturing machines typically include the following key components and functions:

  • Raw Material Supply System: These machines are usually capable of handling various materials required for sanitary napkin production, such as absorbent paper, nonwoven fabric, adhesive, and more. The raw material supply system ensures a continuous supply of materials.

  • Cutting System: Sanitary napkins often need to be cut into specific sizes and shapes. The cutting system is responsible for cutting continuous rolls of material into the appropriate dimensions.

  • Embossing Machine: This machine is used to emboss patterns onto the non-woven fabric, enhancing the appearance of the sanitary napkin while also improving its absorbent capacity.

  • Absorbent Core Manufacturing: These machines typically include equipment for manufacturing the absorbent core of the sanitary napkin, which is the primary absorption component and usually contains absorbent paper and superabsorbent polymer (SAP).

  • Stacking and Assembling System: Sanitary napkin materials usually consist of multiple layers, including an absorbent layer, a top sheet, and a backsheet. The stacking and assembling system ensures that these materials are assembled in the correct order and position.

  • Adhesive System: Sanitary napkins often require the addition of adhesive, acquisition layers (ADL), and backsheet tapes at specific locations. The adhesive system ensures that these elements are correctly attached to the sanitary napkin.

  • Packaging System: Finished sanitary napkins need to be packaged for sale and distribution. The packaging system typically includes equipment for placing the napkins in packaging materials, sealing the package, and adding labels or printed information. The packaging system may also count and sort the napkins.

  • Quality Control: Sanitary napkin manufacturing machines usually feature quality control functions to detect and rectify any defects or issues during production, ensuring product consistency and quality.

How does a sanitary napkin manufacturing machine work?

  1. Raw Material Supply: Firstly, the manufacturing machine retrieves the necessary production materials from the raw material inventory. These materials typically include absorbent paper, non-woven fabric, superabsorbent polymer (SAP), adhesive, and adhesion agents, among others. These materials are introduced into the manufacturing machine through the feeding system.
  2. Cutting and Stacking: The manufacturing machine cuts the raw materials into appropriate sizes and shapes. Subsequently, these materials are stacked together to form the basic structure of the sanitary napkin, including the absorbent core, top sheet, and backsheet.

  3. Adding the Absorbent Core: Some sanitary napkins require the addition of superabsorbent polymer (SAP) to the absorbent core to enhance absorption capacity. The manufacturing machine adds SAP at the designated locations within the absorbent core.

  4. Adhesion and Heat Sealing: The manufacturing machine adds adhesive, acquisition layers (ADL), and other supplementary elements at the appropriate locations. These materials are then heat-sealed to ensure a secure bond.

  5. Cutting and Shaping: The completed structure of the sanitary napkin is cut into the correct size and shape. This process often involves cutting the material rolls into individual sanitary napkin shapes.

  6. Packaging: Finished sanitary napkins are packaged using the packaging system. This typically includes placing the napkins in packaging bags, sealing the bag openings, and adding labels or printed information. The packaging system may also perform napkin counting and sorting.

  7. Quality Control: Manufacturing machines often incorporate quality control mechanisms to detect and address any defects or issues that may arise during production. If problems are identified, the machine may automatically stop or issue alerts to reduce the rate of defective products.

  8. Output: Completed sanitary napkins are conveyed to the output conveyor for further processing, storage, and distribution.
