Nozzle Adapter Prevents Paste Clogging in Dispensing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paste application machines experience nozzle clogging and discontinuous paste material application due to cured material formation when connecting a new nozzle to the nozzle support, leading to failures in applying paste materials effectively.
Innovation Solution
A nozzle adapter system with a first portion having a first channel and a second portion with a second channel, where the second portion has a nozzle connecting part, and the first portion has a hollow part for fitting the second portion, ensuring that the nozzle connects without coming into contact with the paste material, thereby preventing cured material formation and clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new nozzle is connected to a nozzle support with paste material remaining in the channel, then the nozzle can be replaced and used, but cured material is produced at the connection point causing nozzle clogging and application failure
Solution Approach 1:
The invention introduces a nozzle adapter as an intermediary component between the nozzle support and the nozzle. The adapter includes a first portion that connects to the nozzle support and a second portion that connects to the nozzle, with a separating surface between them. This intermediary structure prevents direct contact between the nozzle and the paste material in the nozzle support channel, thereby eliminating the curing reaction that occurs at the connection point while still allowing nozzle replacement.
2Device complexity
If the nozzle is directly connected to the nozzle support, then the structure is simple, but cured material enters the channel causing clogging and discontinuous paste material flow
Solution Approach 1:
The nozzle adapter serves as a mediator that separates the nozzle from the paste material flow path in the nozzle support. The first portion of the adapter connects to the nozzle support while the second portion connects to the nozzle, with the separating surface preventing cured material from entering the channel. This maintains continuous paste material flow while adding only one intermediate component.
3Ease of operation
If the nozzle connects directly to the nozzle support, then the connection is direct and simple, but the cured material formation causes nozzle clogging
Solution Approach 1:
The nozzle adapter acts as an intermediary connection component that maintains operational simplicity while preventing harmful cured material formation. The adapter can be easily attached and detached between the nozzle support and nozzle, providing a simple connection mechanism that simultaneously prevents cured material from clogging the nozzle channel.
Solution Approach 2:
The connection system is segmented into three distinct parts: the nozzle support, the nozzle adapter (with first and second portions), and the nozzle itself. This segmentation allows the adapter to be positioned at the critical interface where paste material contact occurs, preventing curing while maintaining ease of assembly and disassembly.

AI summary
A nozzle adapter comprises a first portion having a first channel; and a second portion having a second channel, a paste material entering the second channel along the first direction and released from the second channel along a second direction, wherein the second portion has a nozzle connecting part, to which a nozzle is connected; a downstream end of the second channel is linked to the nozzle connecting part; the first portion has a hollow part for fitting the second portion, the hollow part being formed along the second direction, or along a third direction; and a downstream end of the first channel is linked to the hollow part.
