Main machine | Automatic roll to roll heating coating Machine |
Vacuum pump | 1.Substrate Fixation: In some coating machines (such as roll coaters, spray coaters, spin coaters, etc.), vacuum adsorption helps fix the substrate (e.g., film or paper) onto the worktable, preventing the substrate from moving or deforming during the coating process. Vacuum adsorption ensures that the substrate remains securely in place within the coating machine’s work area, ensuring the precision and consistency of the coating process. 2.Preventing Substrate Warping or Floating: For flexible materials, vacuum adsorption can prevent the material from warping or floating due to air currents or other forces during the coating process. This is especially important for materials like films and papers, helping to ensure that the coating is applied evenly and smoothly. 3.Improving Coating Precision: By ensuring that the substrate remains fixed in place during the coating process, vacuum adsorption improves the coating precision, reducing substrate displacement or tilting. This helps ensure the uniformity and quality of the coating. 4.Stability During the Coating Process: Vacuum adsorption helps maintain stable contact between the substrate and the coating head or nozzle throughout the entire coating process, reducing issues caused by substrate movement, such as uneven coatings or incomplete coating application. |
Tension control | 1. Maintain uniformity of the film layer During the coating process, the tension of the substrate needs to remain stable. If the tension is uneven, the coated film layer may have uneven thickness, ripples or stretching problems, affecting the quality of the final product. The tension control system ensures the uniformity and accuracy of the film layer by adjusting the tension in real time to ensure that the substrate runs smoothly during the coating process. 2. Prevent material deformation or damage Excessive tension may cause the substrate or coating layer to overstretch, causing the material to crack, wrinkle or break; too little tension may cause the material to relax, fail to coat effectively, or wrinkle. Precise tension control helps to maintain appropriate tension at different stages of the process (such as coating, drying, cooling, winding, etc.), thereby avoiding these problems. 3. Control the feeding and winding process of the coil The roll-to-roll coater adjusts the tension of the substrate during the feeding and winding process through the tension control system to ensure that the substrate can pass through each process evenly and be accurately wound into a roll at the end. 4. Improve coating quality During the coating process, the tension on the surface of the material affects the coating effect of the slurry. Stable tension helps ensure uniform contact between coating equipment (such as scrapers, rollers, etc.) and the substrate, thereby improving the quality of coating. |

Application Case (Preparation of PET film):
In the roll-to-roll (R2R) coating process, PET film (polyethylene terephthalate film) is commonly used in multiple fields, such as packaging, electronics, optical films, etc. The roll-to-roll coating machine can efficiently and accurately coat the functional film layer to improve the performance of the PET film, such as conductivity, UV resistance, light transmittance, etc. The following are the basic steps for preparing PET film using a roll-to-roll coating machine:
1. Substrate preparation
PET film selection: Select the raw material PET film with appropriate thickness and specifications. The thickness of the PET film usually ranges from 12 to 250μm.
Substrate tension adjustment: During the coating process, it is necessary to ensure that the tension of the PET film on the coating machine is uniform. Improper tension may cause the film material to stretch or break, affecting the coating quality.
2. Coating material preparation
Coating slurry preparation: Prepare appropriate coating slurry according to the functional layer to be coated (such as conductive layer, optical film, protective layer, etc.). Common coating materials include:
Solution-type materials: such as conductive polymers, optoelectronic materials, and UV-resistant materials.
Solvent selection: The solvent in the coating slurry needs to be selected according to the properties of the coating. Commonly used solvents include water, alcohols, organic solvents, etc.
Coating viscosity adjustment: The viscosity of the coating slurry needs to be adjusted according to the coating method (such as knife coating, roll coating, roller coating, etc.) to ensure coating uniformity.
3. Coating process
Coating method selection: Select a suitable coating method according to the requirements of the coating layer. Commonly used coating methods are:
Doctor Blade: High coating accuracy, suitable for uniform coating of thin film coatings.
Roller coating: Suitable for large-area coating, with good coating uniformity.
Spraying or dipping: Suitable for fast and mass production.
Coating machine configuration:
Coating head: The coating slurry is evenly coated on the surface of the PET film through the coating head.
Drying system: The PET film after coating needs to be processed by a drying system (such as hot air drying, infrared heating, etc.) to remove the solvent to ensure that the coating layer is dry and stable.
4. Drying and curing
Drying/curing: The PET film after coating needs to be processed by a drying system or curing furnace to remove the solvent or moisture in the coating slurry. Common drying methods include:
Hot air drying: Use hot air heating equipment to quickly dry the coating layer.
Infrared drying: Use infrared heating to quickly evaporate the solvent.
UV curing: If the coating is UV curing paint, you can use a UV lamp to cure it to cure the coating into a film.
5. Quality inspection and control
Coating uniformity detection: Use online measuring instruments (such as coating thickness measuring instruments, surface roughness testers, etc.) to monitor the thickness and uniformity of the coating layer in real time.
Film layer performance test: After coating, it is necessary to test the performance of the film layer, such as optical properties (light transmittance, reflectivity), mechanical properties (tensile strength, elongation at break), chemical stability, etc.
Defect inspection: Check whether there are defects such as bubbles, wrinkles, scratches, etc. in the film layer to ensure that the coating quality meets the requirements.
6. Winding and rewinding
Rewinding: The coated and dried PET film needs to be rewound in the rewinding part of the roll-to-roll coater. At this time, the rewinding tension needs to be precisely controlled to ensure smooth winding and avoid slack or overtightening.
Rewinding tension control: The tension control system is used to ensure that the tension of the film material remains stable during the rewinding process to prevent deformation or damage of the film material.
7. Final processing and packaging
Film cutting and rewinding: On the rewound PET film, cutting and rewinding may be required for subsequent use. When rewinding, it is necessary to ensure that the width, length, roll diameter, etc. of the film material meet the requirements.
Packaging: The finished PET film needs to be properly packaged to prevent moisture, contamination or mechanical damage. Common packaging methods include roll packaging, box packaging, etc.
