Automatic Hydrogel Coating and Cutting Machine

The Automatic Hydrogel Coating and Cutting Machine is an integrated production system designed for the continuous manufacturing of hydrogel-based patches and personal care products. It combines doctor blade coating, material feeding, photoelectric tracking, conveying, pressing, slitting, and cutting in one automated machine.

The machine adopts a doctor blade coating system with a coating thickness tolerance of ±5 μm, supporting controlled hydrogel application onto different substrate materials. It is suitable for processing medical-grade spunlace fabrics, elastic nonwoven fabrics, and other compatible flexible materials.

Designed for stable continuous operation at speeds of 200–250 pieces per minute, the machine integrates automatic counting, positioning, and cutting functions to support efficient production.

Typical applications include hydrogel cooling patches, hydrogel facial masks, hydrogel eye patches, under-eye patches, and other hydrogel-based products.

With customizable product dimensions and flexible material compatibility, the machine can be configured according to different product designs and manufacturing requirements.

Integrated Doctor Blade Coating System

The machine adopts a doctor blade coating method for applying hydrogel formulations onto flexible substrate materials.

The coating system is designed to provide controlled coating thickness, with a specified thickness tolerance of ±5 μm.

The coating process can be adjusted according to hydrogel viscosity, formulation characteristics, substrate properties, and target product requirements.

Hydrogel Feeding System

The machine is equipped with a hydrogel feeding hopper with a capacity of approximately 25 kg.

The feeding system supplies hydrogel to the coating section for continuous processing. Feeding conditions can be adjusted according to the material's flow characteristics and production requirements.

Photoelectric Tracking and Positioning System

An integrated photoelectric tracking system detects material positioning and helps maintain alignment during continuous operation.

This system supports consistent material positioning during conveying, pressing, and subsequent cutting processes.

Pressing, Slitting and Cutting Units

The machine integrates longitudinal pressing, transverse pressing, slitting, and cutting units.

These functional sections work together to process coated materials into individual hydrogel products.

Product dimensions and cutting configurations can be customized according to customer requirements, allowing the machine to accommodate different product shapes and sizes.

 Automatic Production Control

The machine adopts variable-frequency stepless speed adjustment to regulate production speed according to actual manufacturing requirements.

Its automatic functions include:

Automatic product counting.

Continuous material conveying and processing.

Automatic cutting operations.

High-position cutter stopping for convenient adjustment and troubleshooting.

With a stable continuous operating speed of 200–250 pieces per minute, the machine is designed to support high-throughput hydrogel patch manufacturing.

Hydrogel Cooling Patches

Suitable for manufacturing hydrogel cooling patches using compatible nonwoven and elastic fabric substrates. Typical products include forehead cooling patches and other topical cooling products.

Hydrogel Facial Masks

Designed for coating and processing hydrogel facial mask materials, including compatible spunlace fabrics and other flexible substrates.
