Overview
The TBJ-FJLZ-DJ2 Automatic Film Applicator is a China unwinding device that integrates manual unwinding of the head, fixed fixture, automatic feeding, metering rod & doctor blade, heating, vacuum adsorption, fixed fixture at the tail and manual unwinding functions. By precisely controlling the speed and stable pressure, it ensures the uniformity and smoothness of the glue application of the Spreader, providing a larger Spreader area than the ordinary model, effectively solving the problem of artificial film inconsistency.
Features
1. Multi-function integration: with unwinding, automatic feeding, metering rod & doctor blade, heating and vacuum adsorption functions.
2. High Accuracy Control: Spreader rate 5~ 180mm/s (can be customized < 5mm/s), Wire Spreader accuracy +/- 1μm, Spreader accuracy +/- 0.003mm.
3. Large Spreader area: Effective Spreader area 400 * 300mm, vacuum adsorption size 400 * 300mm (can be customized).
4. Customizable options: Support automatic inking system, vacuum adsorption size customization and low speed Spreader customization.
5. Stable performance: Infinitely variable speed control, aluminum alloy Spreader table and vacuum adsorption system are used to ensure uniform Spreader.
Principle
The Film Applicator achieves uniform Spreader by controlling the speed of the Spreader and the steady pressure applied to the film applicator. The automatic feeding system uses the principle of outflow of air source pressure, adjusts the amount of material by reciprocating linear motion, and combines the functions of metering rod & doctor blade and vacuum adsorption to ensure coating conformity and smoothness.
Applications
Spreader coating, sample testing, material coating prepative
Standards
No specific criteria are mentioned
Steps
1. Manually unwind the substrate to the head fixture.
2. Start the automatic feeding system, adjust the air pressure and speed to control the discharge volume.
3. Set the Spreader speed and heating temperature (RT +~ 200 ° C).
4. Spreader with metering rod & doctor blade, vacuum adsorption fixed substrate.
5. After the Spreader is completed, manually rewind to the tail fixing fixture.
Notice
• Spreader rate adjustable range is 5~ 180mm/s, lower than 5mm/s need to be customized.
• The air source pressure of the feeding system is 0.6Mpa, and it needs to be equipped with a φ 8 trachea.
• The maximum pressure of the feeding drum is 8Mpa. Pay attention to the safety valve and pressure gauge when using it.
• Heating Temperature Uniformity is +/- 3 ℃, avoid using beyond the range.
• Optional accessories such as leakage tanks, substrate fixtures, etc. can be configured according to application requirements.
