丨Core Functions
Deeply developed based on hygiene material production technology, the equipment is equipped with a full set of automatic, high-precision and damage-free core functions, which strictly match the refined and high-quality production standards of the industry:
- Multi-material Intelligent Slitting：The machine is equipped with a modular quick‑change tool holder for optional switching between circular knives and razor blades. For PE breathable films, non‑breathable films and composite films with different material properties, operators can replace the matching tool holders and cutters and adjust slitting parameters. Without changing the whole machine, flexible production of various hygiene material films can be realized.
- High-precision Fixed-size Cutting：Equipped with servo positioning & CNC auto width‑adjustment system, it achieves high slitting width precision for various custom narrow‑width slitting. Great dimensional consistency and tight tolerances are guaranteed to satisfy fine, standardized hygiene material production requirements.
- Constant Tension Closed-loop Control, Film Damage-free：Aiming at the thin and stretchable characteristics of hygiene material films, it is equipped with a dynamic constant tension control system to adjust tension in real time throughout the process, eliminating problems such as film stretching, wrinkling, deviation and loose rolling. It completely retains the microporous structure of breathable films without damaging the core waterproof and breathable performance.
- Automatic Deviation Correction：The high-precision photoelectric deviation correction system corrects coil offset in real time to ensure straight and flat slitting. consumables.
- Intelligent Meter Counting & Neat Rewinding：It supports precise meter counting, quantitative cutting and automatic shutdown. The finished rolls are tight, flat, taper-free, uniform in tightness and neat in end face. It can flexibly produce large/small and long/short rolls, perfectly adapting to subsequent high-speed compounding, cutting and forming assembly line operations.
- One-click Parameter Storage, Efficient Order Switching：Equipped with PLC intelligent touch control system, it can store multiple sets of common film production parameters. No repeated debugging is required for material and specification replacement. The production formula can be called with one click, greatly shortening order switching time and improving production efficiency.
丨Industry Application & Functions
PE film slitting is a pre-core process in hygiene material product production. The processing precision and stability of the equipment directly determine the qualification rate of terminal products and the overall production capacity of the production line, playing a vital role in industrial production:
- Standard Raw Material Preprocessing：Original large-width PE film master rolls cannot be directly used for hygiene material product forming production. After precise slitting by this machine, they can be processed into standard narrow-width coils suitable for equipment, connecting subsequent full processes of compounding, pressing, cutting and forming to realize seamless assembly line production.
- Guarantee Core Performance of Terminal Products：It avoids pore blockage and tensile deformation of breathable films during slitting, ensuring the core waterproof, breathable, dry and anti-leakage functions of diaper and sanitary napkin bottom films; it prevents delamination and degumming of composite films, ensuring the structural stability and protective sealing performance of disposable products.
- Unify Product Quality Standards：It solves the problems of size deviation, burrs and defective products caused by manual slitting and ordinary equipment slitting, unifying the size and quality of each batch of finished films and stabilizing the qualification rate of hygiene material.
- Adapt to Industrial Mass Production Demand：Adopting high-speed continuous operation mode, it can match the large-batch and uninterrupted production rhythm of hygiene material, break the bottleneck of raw material processing capacity and support large-scale mass production.
丨Core Advantages
Designed exclusively for the in-depth development of the hygiene material industry, different from universal film slitting machines, it solves industrial pain points targeted with high cost performance and practicability:
- Industry Exclusive Adaptation, No Film Performance Damage：Different from universal slitting equipment, it is specially developed for thin and light hygiene material PE films. With low-speed flexible film feeding and precise knife control, breathable films have no pore blockage or deformation, and composite films have no delamination or degumming. It perfectly retains the core functions of raw materials and reduces the defect rate of terminal products from the source.
- Multi-purpose Machine for Full-category Orders：A single machine is compatible with slitting processing of PE breathable films, non-breathable films and multi-layer composite films. It can switch production of different raw materials without equipment replacement, adapting to multi-product and multi-specification order production of hygiene material enterprises and greatly reducing equipment procurement costs.
- High Precision & Low Loss, Significant Cost Reduction & Efficiency Improvement：The slitting incision is flat without burrs and scrap edge collapse, which greatly improves the utilization rate of raw materials and reduces material waste. With high automation, no special on-duty personnel is required, and one person can operate multiple devices, greatly saving labor costs while the yield rate can reach more than 98%.
- High Speed & Stability, Adapt to Mass Production Lines：Optimized transmission structure ensures no jitter or deviation during high-speed operation. It supports 24-hour uninterrupted continuous operation with stable performance and low failure rate, fully matching the high-intensity mass production rhythm of the hygiene material industry and effectively improving the overall production line capacity.
- Simple Operation & High Fault Tolerance：Intelligent touch operation interface with visualized parameters enables new operators to get started quickly without professional debugging. One-click parameter storage and calling ensures efficient and convenient order switching, adapting to small and medium-batch, multi-frequency order production.
丨Necessity of Equipment Deployment
In the production of sanitary napkins, diapers, disposable medical supplies and other hygiene material, PE film slitting is an indispensable pre-core process. Without special high-precision slitting equipment, enterprises' production capacity, product quality and market competitiveness will be directly restricted:
- Make Up Quality Deficiencies of Universal Equipment：Ordinary film slitting machines cannot adapt to the special material characteristics of hygiene material PE films, and are prone to problems such as breathable film micropore blockage, film tensile deformation, composite film delamination and incision burrs, which directly cause liquid leakage, poor air permeability and appearance defects of terminal products, leading to customer complaints and returns. Special hygiene material slitting equipment can completely avoid such problems.
- Realize Standardized Mass Production：Manual slitting has low precision, low efficiency and large errors, failing to meet the requirements of large-scale and standardized production. Special slitting equipment features accurate size and uniform finished products, serving as the basic guarantee for enterprises' standardized production and stable delivery of high-quality products.
- Meet Industrial Compliance & Quality Upgrade Requirements：With increasingly strict quality standards in the hygiene material and disposable product industry, clean, high-precision and damage-free raw material processing has become an industrial rigid demand. Special slitting equipment is a necessary core equipment for enterprises to achieve compliant production, upgrade high-end products and expand high-quality customers.
