What are the key equipment for producing all resin carbon ribbon?

The key equipment for producing all resin carbon ribbon covers the complete process from substrate processing to coating, drying, and cutting. The following is a technical analysis of the core equipment and its functions:

1. Base film treatment equipment: corona treatment machine

Function: Perform corona treatment on polyester (PET) base film, activate the surface of the base film through high-voltage discharge, and improve adhesion.

Technical details: The processing strength needs to be precisely controlled to ensure uniform coating of the subsequent toner layer and avoid detachment.

2. Coating equipment: high-precision gravure coating machine

Function: Apply back coating, release layer, and ink layer.

Technical details:

Ceramic mesh roller: The number of lines (100-250 lines) determines the coating accuracy and affects the uniformity of the coating.

Coating speed: 60-150m/min, needs to be matched with the drying temperature (60-100 ℃) to ensure that the solvent evaporates fully.

Multi layer coating process:

Back coating: Contains polyurethane and acrylic modified resin, providing anti-static and lubrication functions.

Release layer: coated with a wax mixture for easy detachment of carbon tape from labels.

Ink layer: containing polyester, chloroacetate resin, etc., determining printing clarity and weather resistance.

3. Drying equipment: hot air circulation drying oven

Function: Curing the coating and removing residual solvents.

Technical details:

Temperature control: segmented drying (such as 60 ℃ for the back coating and 80 ℃ for the ink layer) to prevent coating cracking.

Wind speed regulation: Uniform hot air circulation ensures drying efficiency.

4. Cutting equipment: fully automatic carbon strip cutting machine

Function: Cut large rolls of carbon ribbon into specified specifications (such as width 70-110mm, length 300m).

Technical details:

Tension control: The magnetic powder clutch automatically adjusts the winding tension to avoid carbon ribbon wrinkles.

Accuracy guarantee: The PLC control system achieves a cutting accuracy of ± 0.1mm.

Efficiency: Dual station coiling design improves production efficiency.

5. Auxiliary equipment

Mixing mixer: used for uniformly mixing raw materials such as resin, wax, additives, etc.

Quality inspection instrument:

Color density meter: detects printing contrast.

Wear resistance tester: Simulate friction environment to verify the durability of carbon ribbon.

Equipment collaboration process

Base film treatment: Corona machine activates PET base film.

Coating and drying: gravure coating machine layer coating, drying oven curing.

Cutting and packaging: Customized specifications for cutting machines, automatic winding and packaging.

Summary: The production of all resin carbon ribbons relies on core equipment such as corona treatment machines, gravure coating machines, drying ovens, and slitting machines. Their accuracy and synergy directly determine the printing quality, adhesion, and weather resistance of carbon ribbons.
