UV LED Inkjet Printer Guide Rail Cutter for Precise Roll Substrate Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV printers face inefficiencies in substrate replacement and poor cutting accuracy when using roll substrates, requiring manual cutting with scissors or knives.
Innovation Solution
An ultraviolet LED inkjet printer equipped with a printing member, carrying member, supporting platform, and cutting member, featuring a guide rail and cutter that orthogonally extends across the supporting platform, allowing the cutter to abut against and cut the substrate accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual cutting with scissors or knives is used, then the device complexity is reduced, but the cutting accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical cutting (scissors or knives) with an automated cutting member that moves along a guide rail. The cutting member is driven by a driving mechanism that provides automated control, substituting the manual mechanical system with an automated one that achieves both simplicity and accuracy.
Solution Approach 2:
The guide rail serves as an intermediary component between the cutting member and the substrate. It provides a predetermined path for the cutting member to follow, ensuring accurate cutting positions without requiring complex control systems. The guide rail mediates between the simple cutting action and the precision requirement.
2Productivity
If roll substrates are continuously fed, then the substrate replacement efficiency is improved, but the cutting operation becomes inconvenient
Solution Approach 1:
The cutting member is designed to automatically perform cutting operations as substrates pass through the printing platform. The driving mechanism automatically positions and actuates the cutting member without requiring manual intervention, allowing the system to service itself during continuous substrate feeding.
Solution Approach 2:
The cutting member is designed with movable components that can dynamically adjust its position and orientation along the guide rail. This dynamic design allows the cutting operation to adapt to the continuous flow of substrates while maintaining ease of operation through automated control.

AI summary
An ultraviolet (UV) light-emitting diode (LED) inkjet printer includes a printing member for performing printing on a surface of a substrate, a carrying member configured to continuously pull the substrate so that the substrate can be conveyed forward from the printing member, a supporting platform and a cutting member. The supporting platform is provided in front of the carrying member to support the substrate conveyed from the carrying member. The cutting member is provided above the supporting platform, and includes a guide rail and a cutter. The guide rail extends in a direction orthogonal to a direction in which the substrate is conveyed, and extends at least across an area of the supporting platform for supporting the substrate. The cutter is carried on the guide rail, and is movable along the guide rail. The cutter is configured to abut against and cut the substrate on the supporting platform.
