Solution Overview
Problem
Existing textile printing machines are inefficient in handling different wall thicknesses, requiring manual and time-consuming setup changes when switching between printing products of varying thickness, leading to suboptimal ink application and increased ink consumption.
Innovation Solution
A digital printing machine with a vertically adjustable receiving table driven by a motor, allowing for automatic height adjustment based on the printing product's thickness, and an adaptive mechanism to optimize nozzle distance, enabling efficient printing of products with different thicknesses and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiving table is fixed in position, then the machine structure is simple and stable, but it cannot adapt to printing products of different thicknesses, requiring manual setup changes that are time-consuming
Solution Approach 1:
The receiving table is made dynamically adjustable in the vertical direction through a drive mechanism, allowing it to adapt its position according to the thickness of different printing products. This dynamic adjustment capability enables the machine to handle various product types without manual setup changes, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The vertical position of the receiving table is changed as a variable parameter that can be automatically adjusted based on product thickness. By making this parameter changeable through a drive system, the machine achieves versatility in handling different thicknesses while maintaining a relatively simple overall structure.
2Adaptability or versatility
If manual setup changes are made for different product thicknesses, then the machine can print different types of products, but the process is time-consuming and reduces productivity
Solution Approach 1:
The receiving table automatically adjusts its vertical position through the drive mechanism in response to different product thicknesses, eliminating the need for manual operator intervention. This self-adjusting capability maintains adaptability to various product types while significantly improving productivity by removing time-consuming manual setup changes.
3Manufacturing precision
If the distance between printing nozzle and textile is not optimized, then the machine operation is simple, but ink application quality deteriorates with excessive ink or blurred contours
Solution Approach 1:
The vertical position of the receiving table is dynamically adjusted through a drive mechanism to optimize the distance between the printing nozzle and the textile surface. This dynamic adjustment ensures consistent print quality across different product thicknesses without requiring complex manual intervention, balancing precision with operational simplicity.
