Adjustable Removal Belt for Strip Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cutting devices for strip materials, such as textile or steel cord strips, have complex and expensive designs due to the need for a separate vertically movable belt section holder and a complex pick-up mechanism, which increases costs without significant functional improvements.
Innovation Solution
A cutting device with an adjustable removal belt that changes position to support the material during cutting, eliminating the need for a separate belt section holder and using a pivotable sheet metal or frame with a lifting device to adjust the belt's angle, allowing for simpler design and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate vertically movable belt section holder and complex pick-up mechanism are used, then the belt support function is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The invention merges the belt support function directly into the removal belt structure itself. The removal belt is designed with a movable section that can be raised to provide support, eliminating the need for separate belt support holders and complex pick-up mechanisms. This integration maintains the necessary belt support function while significantly reducing device complexity.
Solution Approach 2:
The removal belt is designed to perform multiple functions: it serves as both the material transport conveyor and the belt support structure. By making the removal belt itself adjustable and capable of providing support when needed, the invention eliminates the need for dedicated support devices, thereby reducing overall system complexity while maintaining functionality.

3Ease of operation
If the removal belt is kept at a lower position, then the material tongs can move above it, but the belt cannot support the material during cutting
Solution Approach 1:
The invention makes the removal belt dynamic by enabling it to change its position and configuration based on operational requirements. The removal belt can be raised to a first position to support material during cutting, and lowered to a second position to allow material tongs movement. This dynamic adjustment capability allows the system to adapt between different operational states, resolving the contradiction between support function and operational clearance.
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 reduces the complexity and cost of the cutting device while maintaining functionality by using a single adjustment device to change the belt's position, supporting the material during cutting and transporting it efficiently to a splicing device, thus enhancing operational efficiency and reducing expenses.
