Cooling Device Belt Swing Overflow Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording material cooling devices face issues with deposited matter overflowing from the receiving container when the belt is swung, leading to reduced cooling performance due to accumulated abrasion powder and paper powder.
Innovation Solution
A recording material cooling device with a mechanism allowing the belt to swing relative to the feeding member, featuring a receiving container with a wall surface portion to prevent overflow, and a scraper to remove deposited matter, which includes a collecting box with partition wall ribs to increase storage capacity and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the belt is cooled by the heat sink with predetermined pressure applied, then the cooling efficiency is improved, but the belt is abraded by the heat sink generating abrasion powder that accumulates and reduces heat resistance
Solution Approach 1:
The patent extracts and removes the harmful deposited matter (abrasion powder and paper powder) from the heat sink area using a removing member, preventing it from accumulating and affecting heat resistance while maintaining the cooling function
Solution Approach 2:
The patent discards the harmful deposited matter through the removing member that removes abrasion powder and paper powder from the heat sink area, preventing accumulation that would otherwise reduce cooling performance
2Ease of operation
If the upper unit is swung to separate the belt from the feeding member for feeding abnormality, then the recording material can be removed, but the deposited matter overflows from the receiving container
Solution Approach 1:
The receiving container is segmented into multiple compartments by partition walls, which prevents deposited matter from overflowing during swinging motion by containing it within specific sections
Solution Approach 2:
The patent adds a vertical dimension to the receiving container structure with partition walls that extend upward, creating a three-dimensional containment structure that prevents overflow during the swinging motion
3Reliability
If the removing member is provided to remove deposited matter, then the cooling performance is maintained, but the device complexity increases
Solution Approach 1:
The removing member is merged with the receiving container structure, combining the removal function and containment function into an integrated component assembly that reduces overall device complexity
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 effectively suppresses overflow of deposited matter, maintains cooling performance, and extends the time before the container needs to be exchanged, reducing operational frequency and maintaining efficient cooling.
Implementation Method 1
a cooling member configured to cool the belt in contact with an inner peripheral surface of the belt
Implementation Method 2
the belt is contacted to the heat sink in a state in which predetermined pressure is applied to the heat sink

AI summary
A recording material cooling device includes a belt, a plurality of rollers, a belt cooling member, a recording material feeding member, a deposited matter removing member, a deposited matter receiving container, a roller holding member, and a supporting member for supporting the roller holding member so as to be swingable between a first position where the belt and the recording material feeding member contact each other and a second position where the belt is spaced from the recording material feeding member. The supporting member supports the roller holding member so that a swing center is positioned on one end side with respect to a rotational axis direction of the rollers. The receiving container includes a wall surface portion for preventing overflow of the deposited matter received through an opening of the receiving container when the roller holding member is positioned in the second position.
