Viscous Material Feeder Nozzle with Dividable Bent Feed Route
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viscous material feeders, such as solder printers, face challenges with solder remaining in the feed route due to bent feed routes, which hinder cleaning and make it difficult to check the cleanliness of the interior portions.
Innovation Solution
A viscous material feeder with a nozzle featuring a bent feed route that is dividable along its length, including straight and inclined passage portions with smoothly curved connections, allowing for easy cleaning and maintenance by exposing the feed route and reducing flow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bent feed route is used to guide viscous material from storage to nozzle, then the material flow path is achieved, but cleaning workability deteriorates and material remains in the feed route
Solution Approach 1:
The nozzle body is divided into multiple detachable sections along the feed route, allowing the feed route to be segmented and separated for cleaning. This enables direct access to interior portions that would otherwise be inaccessible in a continuous bent feed route structure.
Solution Approach 2:
The feed route includes a vertically extending passage portion that changes the spatial dimension of material flow. This vertical section provides a straight accessible path for cleaning tools from above, transforming the cleaning approach from horizontal access to vertical access, thereby improving cleaning workability.
2Difficulty of detecting and measuring
If a bent feed route is used, then material guidance is achieved, but interior portions cannot be checked from outside
Solution Approach 1:
By segmenting the nozzle body into detachable sections, the interior of the feed route becomes visible and accessible when sections are separated. This allows direct visual inspection and cleaning of previously hidden interior portions.
Solution Approach 2:
The nozzle sections are designed to be detachable in advance, allowing the feed route to be opened for inspection and cleaning before material hardening occurs. This preliminary accessibility prevents material accumulation issues.
3Ease of operation
If the feed route is made straight and accessible, then cleaning workability improves, but flow resistance increases
Solution Approach 1:
The feed route utilizes vertical space by including a vertically extending passage portion. This three-dimensional routing allows the feed route to maintain smooth continuous flow characteristics while providing vertical accessibility for cleaning, avoiding the need for horizontal bends that would increase flow resistance.
Solution Approach 2:
The feed route passages are designed with smooth curved transitions rather than sharp angles. The vertically extending portion connects smoothly to horizontal sections, maintaining laminar flow and minimizing turbulence, thereby reducing flow resistance while keeping the route accessible.

AI summary
This viscous material feeder (4) includes a nozzle (43) to discharge a viscous material stored in a storage portion (110) storing the viscous material and a feeding mechanism (44) transferring the viscous material from the storage portion to the nozzle and discharging the viscous material from the nozzle. The nozzle has a bent feed route (50) to guide the viscous material from the storage portion to a tip of the nozzle and is configured to be dividable along the bent feed route.
