Fabric Braking Assembly for Stretching and Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric working machines face difficulties in efficiently stretching fabrics and performing maintenance due to the cumbersome placement of fold removal mechanisms adjacent to the working areas, which complicates operations and maintenance.
Innovation Solution
A fabric braking assembly with a system of rollers, including a rotary roller with braking means and idle transmission rollers, is integrated into the fabric working machine, allowing for efficient stretching and easy repositioning to facilitate maintenance by using handling means like linear actuators or kinematic systems to move the braking assembly between operating and rest positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fold removal means are placed immediately adjacent to the working means, then fabric stretching effectiveness is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The fabric treatment system is divided into separate functional modules: the fold removal means is separated from the working means and integrated into an independent fabric supply machine. This segmentation allows each module to be optimized independently while maintaining their functional relationship through the fabric feed path.
Solution Approach 2:
The patent introduces an intermediary fabric supply machine that acts as a mediator between the fabric source and the working machine. This intermediary contains the fold removal means and supplies pre-treated fabric to the working machine, eliminating the need for complex integration of fold removal functionality within the working machine itself.
2Manufacturing precision
If fold removal means are placed immediately adjacent to the working means, then fabric stretching effectiveness is improved, but ease of operation and maintenance worsen
Solution Approach 1:
The fold removal means is extracted from the working machine and relocated to a separate fabric supply machine. This extraction allows operators to access and maintain the working machine without interference from the fold removal mechanism, while the fabric supply machine can be positioned for optimal maintenance accessibility.
Solution Approach 2:
The fabric supply machine is designed with movable and adjustable components, including the fabric braking assembly with adjustable braking force and repositionable fabric braking means. This dynamic design allows easy adjustment and maintenance without requiring complex disassembly procedures.
3Productivity
If fabric braking assembly is used for stretching fabric, then stretching efficiency is improved, but device complexity increases
Solution Approach 1:
The fabric supply machine integrates multiple functions into a single device: it performs fabric centering, fold removal, and stretching operations. The fabric braking assembly serves both as a stretching mechanism and a speed control device, reducing the need for separate mechanisms and overall system complexity.
Solution Approach 2:
The fabric stretching is achieved by adjusting the braking force parameter applied to the fabric. By varying the braking force, the system can control both the stretching degree and the fabric feeding speed, providing efficient stretching through simple parameter adjustment rather than complex mechanical changes.
