Folding Dialysis Paper/Filter Paper Automatic Winding Machine——Precision Manufacturing Solutions

In the medical, biopharmaceutical and laboratory fields, the folding and winding accuracy of dialysis paper and filter paper directly affects the filtration efficiency, sealing and safety of the products. Our fully automatic folding and winding machine is designed for high-demand application scenarios, with intelligence, high precision and sterilization as the core, to ensure that each roll of dialysis paper meets strict quality standards.

Core functions and advantages

1. High-precision folding and winding to ensure product consistency

Intelligent correction system: CCD visual detection + servo correction is used to ensure that the filter paper folding alignment accuracy is ≤±0.1mm, avoiding interlayer misalignment affecting filtration performance.

Adaptive tension control: Real-time adjustment of winding tension (adjustable from 5 to 50N) to prevent stretching deformation or loose winding, suitable for dialysis paper of different weights (30 to 200g/m²).

Multiple folding methods: Support Z-type, W-type, wave-type and other folding processes to meet different needs such as blood bags, liquid filtration, laboratory consumables, etc.

2. Fully automated production, efficient and stable
Automatic unwinding → folding → slitting → winding → packaging integrated process, production speed can reach 30~60 meters/minute, efficiency is more than 20 times higher than manual.

Quick changeover design: modular structure supports switching of different widths (100~600mm) and length specifications, and production change time is ≤5 minutes.

3. Clean production environment, in line with medical standards
Enclosed dust-free design: equipped with HEPA filtration system, the cleanliness of the work area reaches ISO 8 level (100,000 level) to avoid fiber shedding and pollution.

Antistatic treatment: ion wind cleaning of the coil surface prevents electrostatic adsorption of particles and ensures the biosafety of dialysis paper.

4. Intelligent quality monitoring and traceability
Online defect detection: real-time monitoring of pinholes, stains, and poor creases through high-speed cameras, automatic marking and removal of unqualified products.

Data traceability: record the length, tension, and folding parameters of each roll of products, support MES/QMS system docking, and meet FDA 21 CFR Part 11 requirements.

Industry applications
Medical consumables: hemodialysis paper, infusion filter membrane, sterile packaging materials

Biopharmaceuticals: filtration media for vaccines, serum, and cell culture media

Laboratory: filter paper for chromatography analysis and microbial detection

Technological innovation value
Through high-precision automation + digital quality control, the equipment completely solves the problems of low efficiency, large errors, and high contamination risk of traditional manual folding, providing zero-defect manufacturing guarantee for medical-grade filtration materials, and helping the pharmaceutical and medical device industries to improve product reliability and compliance.

Optional upgrades:

Laser marking: Print batch number and production date on the edge of the coil

Automatic packaging machine connection: realize unmanned full process of coil → slitting → vacuum packaging
