Adjustable Drying Apparatus Belt Pivoting for Print Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inkjet recording apparatuses face challenges in aligning the height of the sheet conveyance surfaces between the print and drying modules, leading to potential defects in sheet conveyance due to component tolerances.
Innovation Solution
A drying apparatus with an adjustable conveyance unit, featuring an endless belt system and an adjusting unit that allows for height adjustment of the sheet conveyance surface by pivoting the conveyance unit around a pivot shaft, ensuring alignment with the print module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate casings with adjustable heights are used to interconnect print and drying modules, then assembly flexibility and adaptability are improved, but height alignment precision deteriorates due to component tolerances
Solution Approach 1:
The invention makes the sheet conveyance surface height adjustable through a height adjustment mechanism that allows the drying module to be dynamically repositioned vertically. This enables precise height alignment with the print module while maintaining the modular separate-casing design, thus resolving the contradiction between assembly flexibility and height alignment precision.
Solution Approach 2:
The invention changes the vertical position parameter of the drying module by introducing a height adjustment mechanism. This allows the height parameter to be modified to achieve precise alignment with the print module's sheet conveyance surface, overcoming the height alignment precision deterioration caused by component tolerances in fixed-height modular designs.
2Manufacturing precision
If height adjustment is performed at multiple positions, then height alignment precision is improved, but device complexity increases
Solution Approach 1:
The invention segments the height adjustment function into a dedicated height adjustment mechanism separate from the conveyance unit structure. This segmentation allows the adjustment function to be implemented in a localized, simplified manner rather than requiring complex multi-point adjustments throughout the entire conveyance system, thus improving height alignment precision without excessive complexity increase.
Solution Approach 2:
The invention introduces a height adjustment mechanism as an intermediary component between the drying module and the conveyance unit. This intermediary provides a dedicated, simplified adjustment interface that achieves precise height alignment without requiring complex adjustments at multiple positions throughout the system.

AI summary
A drying apparatus includes an opening portion, a conveyance unit, and an adjusting unit. The opening portion receives the sheet conveyed from the printer unit. The conveyance unit includes an endless belt configured to convey the sheet, a first roller configured to stretch the belt, a second roller arranged upstream of the first roller in the conveyance direction and configured to stretch the belt, and a sheet conveyance surface configured to convey the sheet from the second roller toward the first roller on a surface of the belt. The adjusting unit adjusts height of an upstream side in the conveyance direction of the sheet conveyance surface of the belt by pivoting the conveyance unit at a position further downstream than a center of the sheet conveyance surface in the conveyance direction around a pivot shaft arranged along a rotational axis direction of the first roller as a center.
