From coil to finished product: How does the hot stamping foil slitting machine achieve efficient slitting at the touch of a button?

To achieve one-button and efficient slitting of the hot stamping foil slitting machine from coil to finished product, it is necessary to integrate intelligent control, high-precision slitting technology and automatic process optimization. Here are the step-by-step solutions:

1. The core module of one-click operation

(1) Fully automatic parameter matching

• Material Recognition System:

Through infrared sensor or laser thickness gauge, the material (PET, OPP, laser film, etc.), thickness (12μm~50μm) and metal layer characteristics of hot stamping foil are automatically detected, and the pre-stored tension, temperature and speed parameters are retrieved.

Example: Laser foil needs to reduce the slitting speed (150 m/min) to avoid coating peeling, while ordinary PET foil can be increased to 300 m/min. *

• Barcode/RFID linkage:

The coil label contains slitting requirements (width, length, roll diameter), and the machine automatically configures the tool spacing, winding tension, etc. after scanning the code.

(2) Intelligent slitting execution

• Servo turret cluster:

Multiple sets of independent servo turrets (accuracy ± 0.02mm) adjust the width synchronously according to the instructions, and support dynamic variable specification slitting (such as a roll divided into two widths of 20mm/50mm at the same time).

Advantage: Avoid the time-consuming problem of manual calibration due to the need for shutdown of traditional mechanical tool adjustment. *

• Constant Tension Closed-Loop Control:

Magnetic particle brake + tension sensor adjusts the unwinding/winding tension in real time (usually set to 5~15N) to prevent the hot stamping foil from stretching and deforming or wrinkling.

2. Key technology of high-speed and high-precision slitting

(1) Special tool system

• Low Temperature Slitting Knife:

The titanium-plated alloy round knife is combined with the cooling aerosol device to avoid the adhesion of the hot stamping layer caused by friction and heating during high-speed slitting (≥400m/min).

Comparison: Ordinary steel knives are prone to burrs above 200m/min. *

- Laser online monitoring:

Real-time detection of slitting edge quality, found burrs or flying gold immediately feedback to adjust the knife pressure.

(2) Adaptive deviation correction

• CCD Vision Correction:

The hot stamping pattern (such as the positioning cursor) is tracked, and the deviation correction accuracy is ± 0.1mm to ensure that the slitting does not destroy the integrity of the pattern.

Application scenario: slitting of bronzing logo in the packaging industry. *

3. Automated production flow integration

(1) Unmanned material circulation

• Automatic roll changing manipulator:

After the full reel is fully discharged, the new reel is automatically loaded and the connection time is ≤ 1 minute (5~8 minutes traditionally).

• AGV linkage:

It is connected with the AGV trolley to realize the automatic transportation of raw materials in storage→ slitting → finished products out of the warehouse.

(2) Intelligent quality control and traceability

• Defect Detection System:

The high-speed camera detects scratches and bubbles in the hot stamping foil after slitting, and automatically marks the defective sections and rejects them.

• Blockchain Traceability:

Each roll of finished products generates a unique ID, and records slitting parameters, operators, and quality inspection data for customers to scan the code for query.

4. Comparison of efficiency improvement data

5. Implementation points

• Selection suggestion: Choose a model equipped with servo motor + CCD deviation correction + Internet of Things interface, such as the high-end models of Omet and Bando Machinery.

• Maintenance highlights: daily cleaning of the optical sensor, weekly lubrication of the cutter shaft, regular calibration of the tension system.

• Risk prevention and control: Set up an emergency module to automatically stop and alarm when the foil is broken or over-temperature.

summary

The hot stamping foil slitting machine can achieve the following through one-button intelligent control + high-speed precision slitting + full-process automation:

• The production cycle is shortened by 30%~50%, especially suitable for short-term fast reverse orders;

• Material loss rate is reduced to less than 1%, significantly reducing the cost of gold foil;

• Seamless transition from coil to finished product towards the "Black Light Factory" standard.

(Note: The specific parameters need to be adjusted according to the type of hot stamping foil and the model of the equipment, and it is recommended to carry out small batch trial production verification first.) ）
