Wiping Device for Inkjet Ejecting Heads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiping devices for ejecting heads in image forming apparatuses face challenges in effectively removing attached matter from the side surfaces of nozzle-formed surfaces, leading to potential ink stains on the paper.
Innovation Solution
A wiping device comprising an impregnated member with a contact surface, where the contact surface is longer than the nozzle-formed surface in both longitudinal and transverse directions, contacts and wets the nozzle-formed surface, and a wiping member removes the wetted ink and attached matter, utilizing a cleaning liquid to dissolve and remove ink and foreign particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wiping member directly wipes the nozzle-formed surface, then attached matter can be removed, but the side surface of the ejecting head cannot be effectively cleaned and ink stains may occur
Solution Approach 1:
An impregnated member soaked with cleaning liquid is introduced as an intermediary between the wiping member and the nozzle-formed surface. This impregnated member first wets the nozzle-formed surface and dissolves attached matter, enabling the wiping member to effectively remove both the nozzle surface contaminants and side surface attached matter without causing ink stains on paper.
Solution Approach 2:
The impregnated member performs preliminary wetting and dissolution of attached matter on the nozzle-formed surface before the wiping member makes contact. This preliminary action softens and loosens the attached matter, making the subsequent wiping process more effective and preventing direct mechanical contact that could cause ink stains.
2Ease of operation
If the contact surface of the impregnated member is smaller than the nozzle-formed surface, then the impregnated member can be easily managed, but thorough wetting and cleaning of the entire nozzle-formed surface cannot be achieved
Solution Approach 1:
The impregnated member is designed with a contact surface that extends not only in the longitudinal direction but also in the transverse direction beyond the nozzle-formed surface boundaries. This two-dimensional extension ensures complete coverage of the nozzle-formed surface including side surfaces, achieving thorough wetting and cleaning without compromising operational manageability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures thorough removal of ink and foreign matter from the nozzle-formed surfaces, reducing ink stains on the paper and maintaining the integrity of the ejecting heads, while the cleaning liquid effectively dissolves and redeposits ink, preventing clogging and ensuring continuous operation.
Implementation Method 1
The impregnated member causes the contact surface to contact with the nozzle-formed surface and wet the nozzle-formed surface
Implementation Method 2
the cleaning liquid effectively dissolves and redeposits ink
Implementation Method 3
The wiping member wipes the nozzle-formed surface wetted by the impregnated member

AI summary
Provided is a wiping device including: an impregnated member that is impregnated with a liquid, has a contact surface having lengths which are longer than that of a nozzle-formed surface in a longitudinal direction and in a transverse direction intersecting with the longitudinal direction of the nozzle-formed surface of an ejecting head that ejects an ejection liquid, and causes the contact surface to come into contact with the nozzle-formed surface such that the nozzle-formed surface is wetted; and a wiping member that wipes the nozzle-formed surface wetted by the impregnated member.
