Corrugated Box Machine Displacement Mechanism for Quick Blade Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing corrugated paperboard box making machines require significant time for replacing cutting blades when switching between normal and large-size corrugated paperboard sheet production, due to the need for attaching and detaching cutting blades equipped with punching dies, which increases setup time and complicates the production process.
Innovation Solution
A corrugated paperboard box making machine with a displacement mechanism that allows the cutting blade to be selectively set in a cutting or non-cutting position, eliminating the need for blade attachment and detachment, and enabling quick switching between cutting and punching operations using a single die-cutter system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cutting blade-equipped punching die is attached to the blade-mounting cylinder for cutting large-size corrugated paperboard sheets, then cutting capability is achieved, but replacement time increases due to multiple attachment positions required
Solution Approach 1:
The patent combines the cutting blade and punching die into a single integrated assembly that can be mounted once on the blade-mounting cylinder. This merged structure eliminates the need for separate attachment of cutting blades and punching dies, reducing replacement time while maintaining both cutting and punching capabilities.
Solution Approach 2:
The cutting blade-equipped punching die serves multiple functions: it can perform cutting operations when needed and punching operations at other times. This multi-functional component replaces the need for separate cutting and punching tools, enabling quick switching between operations without full replacement of components.
2Adaptability or versatility
If multiple punching dies are attached to the blade-mounting cylinder for different corrugated paperboard sheet sizes, then production versatility is improved, but setup time increases due to frequent replacement work
Solution Approach 1:
The system employs a movable or adjustable mechanism that allows the single cutting blade-equipped punching die to be repositioned or reconfigured for different cutting positions and configurations. This dynamic adjustment capability enables the same component to handle various corrugated paperboard sheet sizes without requiring physical replacement of the die assembly.
