Outpouring Assembly Paste Discharge Pipe Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backflow outpouring assemblies in color mixers face issues with precision due to surface tension of color pastes adhering to outlet surfaces, leading to incomplete discharge and inefficient cleaning of residual pastes.
Innovation Solution
A backflow outpouring assembly with a paste discharge pipe having a thin-wall lower end and oscillating mechanism, combined with a sloped contact surface between the valve member and outpouring plate, facilitates downward gathering and easier cleaning of residual pastes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional paste discharge channel is used, then the structure is simple, but the color paste adheres to the outlet due to surface tension, reducing outpouring precision
Solution Approach 1:
The paste discharge channel is segmented into an upper discharge portion and a lower storage portion, with the outlet positioned at the lower end. This segmentation allows the color paste to be stored in the lower portion and discharged controllably, preventing adhesion issues at the outlet and improving outpouring precision.
Solution Approach 2:
The paste discharge channel transitions from a conventional horizontal or simple vertical structure to a multi-dimensional configuration where the outlet is positioned at the lower end, creating a vertical discharge path. This dimensional change utilizes gravity to prevent adhesion and improve discharge precision.
2Ease of operation
If a conventional outpouring assembly is used, then the cleaning mechanism is simple, but the residual color paste cannot be cleaned effectively
Solution Approach 1:
The lower end of the paste discharge channel is designed as a detachable cleaning component that can be separated from the main body. This allows the cleaning mechanism to access and remove residual color paste effectively from the outlet area, improving cleaning effectiveness while maintaining reasonable structural complexity.
3Strength
If the paste discharge pipe wall thickness is increased, then the structural strength is improved, but the adhesion of color paste to the outlet increases
Solution Approach 1:
The paste discharge pipe is designed with varying wall thickness: the upper portion has sufficient wall thickness for structural strength, while the lower discharge portion has reduced wall thickness to minimize color paste adhesion at the outlet. This local quality variation resolves the contradiction between strength and precision.
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
Enhances the precision of color paste discharge and simplifies the cleaning process by reducing adhesion and allowing for effective collection of residual pastes.
Implementation Method 1
Because of tension of a liquid such as a color paste, the liquid is easily adsorbed at a paste outlet of a paste discharge channel
Implementation Method 2
the paste discharge pipe is subjected to downward force to extend downwards and is subjected to upward force to retract
Implementation Method 3
A contact surface between the first valve member and the outpouring plate is slope surfaces... facilitates downward gathering and easier cleaning of residual pastes

AI summary
An outpouring assembly, comprising an outpouring plate (20), wherein the outpouring plate (20) is provided with a liquid outlet through hole (201), a paste discharge pipe (22) is disposed in the liquid outlet through hole, the paste discharge pipe moves up and down in the liquid outlet through hole, and when a lower end of the paste discharge pipe extends out of the liquid outlet through hole, the paste discharge pipe is in a liquid outpouring state. A beneficial effect of the present invention is as follows: Because a liquid such as the color paste or water has surface tension, the color paste adheres to a surface of an outlet, outpouring precision of the outpouring assembly is affected. A paste discharge pipe (22) is disposed in the liquid outlet through hole (201), so that a quantity of color pastes adhered to a paste discharge outlet of the paste discharge pipe can be effectively reduced.
