Modular Textile Drafting Device for Large Cans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile fiber sliver drafting devices face limitations in accommodating larger cans due to structural constraints and transportability issues, making it impractical to scale up for increased can size without compromising efficiency or becoming too heavy.
Innovation Solution
The stretching device is designed with a multi-part storage housing and base plate, allowing for the accommodation of 1200 mm diameter cans, with a stiffened construction that enables transportation in an assembled state, using a combination of main and side plates and strategically placed columns to maintain mechanical resilience and facilitate lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stretching device is enlarged to accommodate larger cans with 1200 mm diameter, then the productivity and efficiency are improved, but the weight and transportability deteriorate
Solution Approach 1:
The stretching device is divided into multiple modular components including a base plate module, storage housing module, stretching unit module, and drive unit module. Each module can be independently manufactured, transported, and assembled, allowing the large device to be moved in manageable sections despite its overall size and weight
2Productivity
If the stretching device is enlarged to accommodate larger cans with 1200 mm diameter, then the productivity and efficiency are improved, but the ease of transport deteriorates
Solution Approach 1:
The device is segmented into transportable modules that can be moved separately and assembled on-site, directly addressing the contradiction between large size needed for productivity and ease of transport
Solution Approach 2:
The device transitions from a static, fixed installation to a dynamic, movable system through modular design with connection elements that allow assembly and disassembly, enabling the large stretching device to be repositioned as needed
3Reliability
If the stretching device is designed as a single integrated unit for stability, then the reliability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The device is divided into functional modules (base plate, storage housing, stretching unit, drive unit) that can be manufactured independently using standard processes, then assembled with connection elements to form a stable integrated system
Solution Approach 2:
Multiple independently manufactured modules are combined through connection elements to form a unified, stable stretching device, achieving both ease of manufacture through modular production and reliability through integrated assembly

AI summary
A drawing device (1) for textile fiber tapes comprises a drawing unit (10) mounted on a storage housing (11) and a base plate (12) on which at least one storage container (13) can be rotatably mounted. The storage housing (11) is arranged above the base plate (12) at intervals by means of columns (14). The drawing device (1) is designed such that at least one storage container (13) with a diameter of 1200 mm can be mounted on the base plate (12) and filled with the textile fiber tape. The storage housing (11) and the base plate (12) are each formed in multiple parts. The storage housing (11) and/or the base plate (12) are also designed to be stiffened in such a way that the drawing device (1) can be transported in an assembled state. A drawing system (100) is provided with a first drawing device (1) and with a second drawing device (1), each according to the aforementioned design.
