Hydrogel Die Cutting Machine

Junssen is a Manufacturer of round die-cutting machines. The Hydrogel Die Cutting Machine is a specialized equipment that performs continuous die-cutting processing on roll-type materials through the rotation of circular die rollers. It belongs to the sub-category of post-print processing equipment in the light industry machinery sector.

Structure

The overall structure of the rotary die cutting machine consists of six major parts: unwinding unit, feeding traction unit, die cutting main unit, waste discharge unit, winding/slicing unit, and electrical control unit. Each unit contains multiple sub-functional components. The components of the Multi-Station Rotary Die Cutting Machine work collaboratively to achieve continuous processing.

1. Unwinding Unit

The unwinding unit serves as the raw material input port for the equipment. Its primary function is to steadily feed the roll material to be processed, preventing tension fluctuations that could affect die-cutting accuracy. Depending on the form of the raw material, there are two types of structures: single-roll unwinding and multi-roll unwinding:

2. Feed and Tension Control Unit

The feed and tension control unit is responsible for steadily conveying the material from the unwind unit to the die-cutting station. Its primary function is to eliminate fluctuations in unwind tension, ensuring that the material entering the die-cutting station maintains constant tension and a stable feed speed

3. Die-Cutting Main Unit

The die-cutting main unit is the core processing unit of a rotary die-cutting machine; all die-cutting and forming operations are performed here. Its core components include the die roller, the backing roller, the pressure adjustment mechanism, and the die holder body

4. Waste Removal Unit

After die-cutting is complete, excess waste material must be separated from the finished product and removed. Depending on the form of the waste, waste removal units are classified into two types: edge waste removal and inner hole waste removal

5. Winding/Slitting Unit

After waste removal, the finished product can be output in two ways depending on requirements

6. Electrical Control Unit

The electrical control unit serves as the“brain”of the equipment, coordinating the operation of all components and controlling processing accuracy and speed

Component function

The unwinding unit is the input port for raw materials in the equipment. Its main function is to steadily release the raw material rolls to be processed, avoiding tension fluctuations of the rolls that may affect the die-cutting accuracy. According to the shape of the raw materials, it is divided into single-roll unwinding and multi-roll unwinding structures. The unwinding frame is divided into fixed type and air-expand type. Usually, it is combined with a magnetic powder brake to achieve tension control. The air-expand shaft relies on air pressure to control the expansion of the key to fix the roll core of the material. During material replacement, the pressure is released to quickly remove the core. The replacement efficiency is much higher than that of the fixed type shaft. The tension controller is divided into manual tension and automatic tension. Conductive Gel Sheet Die Cutter uses vector frequency automatic tension control, which can adjust the braking torque in real time according to the change in the roll unwinding diameter to maintain a constant unwinding tension and avoid the material from breaking due to excessive tension in thick materials or wrinkling due to insufficient tension in thin materials.

Processing technology

Circular knife die-cutting mainly consists of full-cut and half-cut processes. They are suitable for Medical Gel Converting Lines:

1. Full-cut process: Completely cuts the material. This is mostly used for forming processing on the outside of the finished product. The die-cutting pressure needs to be precise to ensure that all positions can be cut, and excessive pressure should be avoided to prevent damage to the bottom roller and reduce the lifespan of the cutting tool.

2. Half-cut process: Only cuts the upper layer of the material. It does not require cutting the release paper or the base film. It is the most commonly used processing method. The equipment pressure regulation accuracy is required to be high, and the die-cutting depth should be uniform to avoid problems such as incomplete cutting or cutting through the release paper.
