Printer Cutting Head Coupling With Rotatable Magnet Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling mechanisms for print and cutting heads in printers suffer from unstable coupling forces due to the curvature of the magnet-supporting member under impact loads, leading to inconsistent adsorption and reduced stability.
Innovation Solution
A coupling mechanism with a rotatable magnet support and reinforcing structure, allowing precise alignment and increased rigidity through adjustable orientation of the magnet and adsorption body, ensuring stable coupling and decoupling of print and cutting carriages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a low rigidity member is used to support the magnet, then the ease of manufacture is improved, but the member curves under impact load, causing unstable coupling force
Solution Approach 1:
The support member is designed to be rotatable around a first axial line extending in a first perpendicular direction, allowing dynamic adjustment of the magnet's orientation to maintain parallel alignment between adsorbing surfaces during coupling and separation operations, thereby preventing curvature-induced misalignment while maintaining manufacturing simplicity
Solution Approach 2:
The invention introduces rotation around a first axial line (first perpendicular direction) to add a degree of freedom in the perpendicular dimension, enabling the magnet to self-align and maintain stable adsorption despite impact loads, thus resolving the contradiction between ease of manufacture and coupling stability
2Reliability
If the magnet support structure is made more rigid to prevent curvature, then the coupling force stability is improved, but the device complexity increases
Solution Approach 1:
Instead of increasing structural rigidity, the invention uses a rotatable support member that dynamically adjusts the magnet's position, maintaining coupling stability through motion rather than stiffness, thereby avoiding increased device complexity
Solution Approach 2:
The invention changes the operational parameter from static rigid support to dynamic rotatable support, allowing the system to adapt to impact loads through rotational movement, thus maintaining reliability without increasing complexity
3Force
If the magnet and sheet metal are coupled with increased contact area using a rubber member, then the adsorption force is strengthened, but the support member is more susceptible to curvature under impact load
Solution Approach 1:
The rotatable support member compensates for curvature and maintains parallel alignment between the magnet and sheet metal adsorbing surfaces during coupling and separation, ensuring stable adsorption force while accommodating the flexibility of the rubber member without compromising surface parallelism

AI summary
In a printer including a cutting head, a coupling mechanism includes a magnet, a first support provided on one of a print carriage and a cut carriage and supporting the magnet, and an adsorption body provided on the other of the print carriage and the cut carriage and adsorbable to the magnet. The first support includes a support portion supporting the magnet, an attachment portion attachable to the one of the print carriage and the cut carriage, and a reinforcing portion connected with the support portion and the attachment portion, and is rotatable around a first axial line extending in a first perpendicular direction crossing a main scanning direction perpendicularly, with respect to the one of the print carriage and the cut carriage.
