Elastic Body Roller With Low Hardness Silicone Outer Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elastic body rollers used for feeding and printing linerless labels face issues with adhesive attachment, leading to label sticking and maintenance challenges, and struggle with anti-stick and release properties, especially when handling labels with liners or film bases.
Innovation Solution
An elastic body roller design featuring an inner layer elastic material member and an outer layer made of silicone resin with a C hardness of 20 degrees or less, providing non-stick and release properties while maintaining necessary frictional force and anti-wear capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a silicone rubber material is used for the platen roller to prevent adhesive attachment, then the release property is improved, but the frictional force (gripping force) is insufficient causing feeding slippage
Solution Approach 1:
The patent employs a composite structure consisting of a platen roller surface treated with a fluororesin coating or plasma treatment. This composite approach combines the low surface energy properties of fluororesin (providing release properties) with the underlying silicone rubber material (providing frictional force), thereby simultaneously achieving both release property and gripping force without contradiction.
2Reliability
If the platen roller is cleaned or exchanged to maintain feeding function, then the feeding reliability is improved, but the maintenance frequency and operational time loss increase
Solution Approach 1:
The patent implements a self-service mechanism through the fluororesin coating or plasma treatment on the platen roller surface, which inherently prevents adhesive attachment and label sticking. This self-release property eliminates the need for frequent manual cleaning or roller exchange, allowing the system to maintain feeding reliability over extended periods without intervention, thereby reducing maintenance time and operational disruptions.
3Reliability
If a groove is formed on the platen roller surface to reduce contact area, then the release property is improved, but the manufacturing complexity and surface precision requirements increase
Solution Approach 1:
Instead of modifying the physical geometry of the platen roller surface through grooves, the patent changes the surface parameter by applying a fluororesin coating or plasma treatment. This chemical/physical surface modification alters the surface energy characteristics to provide release properties without introducing structural complexity, maintaining a simple cylindrical roller geometry while achieving the desired release effect.

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 roller effectively prevents adhesive attachment, ensures stable feeding and printing of linerless labels and labels with liners, and exhibits minimal wear over extended use, maintaining performance and accuracy.
Implementation Method 1
an outer layer elastic material member composed of a silicone resin having a C hardness of 20 degrees or less that is in contact with a belt-shaped member
Implementation Method 2

AI summary
An elastic body roller which has an excellent non-stick property or release property, and frictional force (gripping force) and is able to stably feed and guide a belt-shaped member such as a linerless label, a typical liner label, or the like is provided. Attention has been paid to coating an outer layer of an inner layer elastic material member having a silicone resin (a outer layer elastic material member) with a C hardness (hardness by a spring-type Asker C type defined in the SRIS 0101 standard) set low. An elastic material member of an elastic body roller has an inner layer elastic material member provided on the outer periphery of a roller shaft, and a outer layer elastic material member provided on the outer periphery of the inner layer elastic material member and being in contact with a belt-shaped member, and the outer layer elastic material member is formed from a silicone resin with a C hardness of 20 degrees or less.
