Swingable Wiper Blade Load Control for Inkjet Nozzle Cleaning

The blade load is controlled by changing the swing angle parameter rather than increasing blade stiffness or force. By precisely adjusting the swing angle to a small range (e.g., 1-5 degrees), the blade applies sufficient load to remove ink residue while keeping the maximum load below the threshold that would damage the water-repellent film.

The blade is designed to swing dynamically rather than remain fixed, allowing the contact point and contact duration to be controlled. The blade swings in contact with the nozzle surface during holder movement, creating a controlled dynamic interaction that removes ink without excessive static pressure that would damage the film.

Each blade is independently supported by its own shaft rather than being fixed to a common rotational shaft. This segmentation allows each blade to be adjusted independently according to the specific requirements of each inkjet head, eliminating the need for complex gear mechanisms while maintaining manufacturing simplicity.

Each blade is made swingable on its support shaft rather than being fixed, allowing dynamic adjustment of the blade angle. The blade can swing within a controlled range to achieve the optimal contact angle with the nozzle surface, providing flexibility without requiring complex adjustment mechanisms.

The blade swing range is precisely controlled within a small angular parameter range (e.g., 1-5 degrees) rather than allowing free swinging. This parameter control enables the blade to adapt to nozzle surface variations while preventing excessive swinging that would cause blade deformation or disengagement from the nozzle surface.

A support shaft acts as an intermediary between the blade and the holder, providing a controlled pivot point. The shaft allows the blade to swing within a limited range to adapt to nozzle surface variations while constraining the movement to prevent blade deformation, serving as a mechanical mediator that balances adaptability and stability.

Each blade is swingable rather than fixed, allowing it to dynamically adjust its position and contact force. This dynamic capability compensates for dimensional and assembly errors, enabling each blade to achieve equal load application despite variations in manufacturing tolerances and positioning accuracy during assembly.

Each blade automatically adjusts its own swing angle and contact position through the swingable mechanism, without requiring precise pre-adjustment during assembly. The blade self-adjusts to achieve optimal contact with its corresponding nozzle surface, eliminating the need for complex adjustment procedures and ensuring equal load distribution despite assembly variations.
