Transporting Belt Drying Section for Liquid Discharging Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid discharging apparatuses using endless transporting belts, the mist of discharged liquid often adheres to the belt's contact face with rollers, leading to slippage and degradation of transport accuracy.
Innovation Solution
Incorporating a drying section that dries the liquid adhering to the contact face of the transporting belt, either through air-blowing, heating rollers, or infrared heaters, to prevent moisture and subsequent slippage, along with a cleaning section to manage ink deposits and maintain transport accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transporting belt is used to transport the medium, then the medium can be continuously transported, but liquid mist adheres to the contact face causing slippage and degradation of transport accuracy
Solution Approach 1:
The patent extracts and removes the harmful liquid mist from the contact face using a blowing unit that blows air to remove the liquid. This separates the transport function from the contaminating effect, allowing continuous transport while maintaining accuracy by actively removing the slippage-causing liquid layer.
Solution Approach 2:
The patent introduces air as an intermediary substance between the liquid mist and the contact face. The blown air acts as a mediator to carry away the liquid mist, preventing direct adhesion to the contact face and eliminating the slippage problem while preserving continuous transport capability.
2Manufacturing precision
If the contact face is dried to prevent slippage, then transport accuracy is maintained, but additional drying components increase device complexity
Solution Approach 1:
The blowing unit serves multiple functions: it dries the contact face to prevent slippage, removes liquid mist, and can be integrated with existing transport components. This multi-functionality maintains transport accuracy while minimizing additional device complexity by making a single component perform multiple protective roles.
Solution Approach 2:
The system uses the existing air supply infrastructure and the natural flow characteristics of the transporting belt to achieve self-drying. The blowing unit leverages the belt's movement and existing air sources, allowing the system to maintain its own contact face dryness without requiring separate complex drying mechanisms.

AI summary
A liquid discharging apparatus includes a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium by a support face being a face on an opposite side from a contact face with the roller, to transport the medium in a transport direction, a liquid discharging unit configured to discharge a liquid onto the medium supported by the support face, and a drying section configured to dry, from a side of the contact face, the liquid adhering to the contact face.
