Exploring Customized Diaper Manufacturing: The Role Of Type I Machines in Effortlessly Transitioning Across Various Sizes And Materials.

China's diaper sector is evolving from uniform manufacturing to tailored and adaptable production, propelled by increased maternal and infant consumption and the need for environmental safeguarding. The Type I diaper machine, pivotal in production, leverages its modular design, smart control mechanism, and adaptable material technology to encompass a broad range of scenarios, from infant diapers to adult incontinence items, and from conventional non-woven fabrics to organic materials, offering brands an essential instrument for overcoming uniform competition.
I. Modular Architecture: The Physical Production of "Building Blocks"
The fundamental breakthrough of the Type I diaper machine is its modular architecture, segmenting the manufacturing process into distinct operational units like raw material processing, core shaping, composite assembly, and packaging. Using the Jiangsu Jinwei JWC-NK900-SV full-service gear as a case study, it facilitates swift connectivity among modules via uniform interfaces. In the process of altering product details, it's only necessary to substitute the specific module's mold (like the waistband cutting blade and the guide layer glue spray head), thereby shortening the transition time from 2 hours using conventional tools to 15 minutes.
The design accommodates an adaptable manufacturing approach involving "modest quantities, diverse types."Take, for instance, a brand's creation of a specialized product range for infants with delicate skin. By substituting the ultra-thin core forming module with the natural cotton surface embossing module, the product's thickness was decreased from 4.2 mm to 2.8 mm, yet the speed remained at 600 pieces per minute, and the surface friction coefficient was lowered by 40%.Additionally, the modular design cuts down on the expenses of maintaining equipment-if a module malfunctions, it allows for the swift substitution of an extra module to maintain production, thus preventing total line outages.
II.Smart Control System: Digital "One-Click Switching" Feature
Expanding on the physical components, the smart control mechanism in the Type I diaper machine facilitates the digital handling of production variables.The all-servo 600P machinery from Shengquan Machinery, in partnership with a PLC (Programmable Logic Controller) and HMI (Human-Machine Interface), is capable of holding over 200 product process formula sets, spanning product widths from 80mm to 175mm and lengths from 200mm to 450mm.Simply enter the desired size on the touchscreen, and the system will adjust itself accordingly:
Mechanical specifics: The waistband stretching apparatus is powered by a servo motor, meticulously altering the elastic waistband's stretch proportion from 1:1.5 to 1:2.2;
Procedure specifics: The ultrasonic welding apparatus adapts its welding power in sync with the thickness of the material (0.3mm-1.2mm), guaranteeing a minimum peel strength of 15N between the impervious partition and the primary structure;
Quality metrics: The uniformity in the distribution of the core SAP (superabsorbent polymer) is tracked in real-time by a machine vision system.If there's more than a ±5% variation in local density, the spray nozzle activates on its own as a compensatory action.
The "one-click switching" feature enables the daily single-line production to flexibly adjust to market needs.As an illustration, at the "618" shopping event, a manufacturing facility employed a smart system to modify its daily output from the standard 1.2 million items to 1.8 million, simultaneously broadening the range of product details from 5 to 12, encompassing subcategories like prolonged night-use and models specific to early childhood education institutions.
III.Material Adaptation Technology: Transitioning from "Usable" to "Superior." The Type I diaper machine addresses the issue of conventional machinery being "incompatible" with the prevalent adoption of novel raw materials like bio-based and biodegradable plastics via material adaptation technology.Using bamboo fiber as a case in point, its brief length and weak cohesion predispose it to clumping in the core during conventional hot-pressing methods.The 3D core molding unit of Jinwei Machinery utilizes bamboo fiber effectively via these innovative methods:
Application Technology for Layered Adhesive: A variety of viscosity adhesives are applied to both the top and bottom layers of the core.To secure bamboo fiber, the top layer employs a low-viscosity adhesive (500 mPa·s), and the bottom layer utilizes a high-viscosity adhesive (2000 mPa·s) for attaching SAP particles, enhancing the core's resistance to deformation by 30%.
Process of Negative Pressure Molding: During the core composite phase, a device for vacuum adsorption is implemented.To ensure uniform absorption of bamboo fiber onto the mesh belt, a negative pressure of -80 kPa is applied, preventing the breakage of fibers due to conventional mechanical pressure.
Dynamic Drying System: Leveraging bamboo fiber's superior moisture absorption, the temperature in the drying tunnel is methodically lowered from the standard 120°C to a range of 90°C-110°C, maintaining a moisture level of ≤3% and averting carbonization of the material from elevated temperatures.
A specific bamboo fiber diaper brand, developed through this method and evaluated by SGS, exhibited an absence of formaldehyde (<5mg/kg) and a total heavy metal concentration ≤80mg/kg, aligning with EU Ecolabel's certification criteria.Additionally, the manufacturing expense for each diaper is 18% less compared to conventional items.
Fourth.Ongoing Optimization Driven by Data: Transitioning from Production Based on Experience to Production with Prediction
The ingenuity of the Type I diaper machine is evident in its extensive use of production data.The Manufacturing Execution System (MES) of Shengquan Machinery is capable of gathering more than 1200 production metrics instantaneously, encompassing:
Status of Equipment: Temperature of Servo motors, cylinder pressure, tension of transmission belts;
Quality Information: Weight of the core, permeability of the surface, and the height of the side panels that are leak-resistant;
Data on Energy Usage: Usage of electricity, water, and gas per diaper.
Utilizing AI algorithms for data analysis, the system is capable of accomplishing the following:
Forecasting Upkeep: Should there be a 15% variance in a servo motor's vibration frequency from the standard level, an alert is dispatched 48 hours beforehand to substitute the bearing, thus preventing unexpected operational interruptions;
Optimization of Process: Upon detecting a high leakage rate in a product batch, the system autonomously modifies the angle and volume of the glue nozzle, thereby decreasing the leakage rate from 1.2% to 0.3%.
Energy Management: The schedule for production is auto-modified according to the prices of off-peak electricity (for instance, 22:00-6:00), leading to a 22% decrease in the daily cost of electricity per line.
Post-implementation of this system, a factory witnessed a rise in its total equipment efficiency (OEE) from 78% to 92%, a 31% reduction in per-product energy usage, and achieved the EU ERP energy efficiency certification, essential for penetrating the German market.
V. Impact on the Industry: Redefining Standards for Flexible Manufacturing
The advancement in Type I diaper machine technology is propelling the industry to adopt a "production-on-demand" approach.Its worth is found in:
For cost optimization, modular design boosts the use of equipment to 92%, boosts the daily single-line production from 120,000 to 180,000 units, and leads to a 25% reduction in the cost of spare parts inventory.
Market adaptability: Smart switching features empower brands to swiftly cater to specific market needs, including the creation of mobile packaging for travel situations and extremely tiny items for preterm babies;
Adhering to environmental norms: The adoption of material adaptation technologies boosts the use of bio-based substances by 40%, aiding brands in achieving global benchmarks like FSC forest certification and OK biodegradable certification.
Data from the China Paper Industry Association forecasts that by 2025, factories equipped with Type I machinery will hold a 35% stake in bespoke products, marking a 22% rise from 2020.With an increasing number of Chinese companies challenging the traditional belief in the superiority of "international brands" through "flexible manufacturing," the Type I diaper changing machine is emerging as an "invisible champion" in the realm of industry enhancement, reshaping competitive dynamics in the worldwide maternal and infant market.
