Application Nozzle With Segmented Clamping Plates For Viscous Material Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application nozzles for viscous materials suffer from leaks due to the radius-ed transition between the nozzle holder and clamping plates, leading to poor tightness and mechanical instability during use.
Innovation Solution
The nozzle design features sharp-edged clamping plates as separate components with acute angles and a thickened nozzle body, along with two nozzle plates that form the application channel, ensuring precise fitting and enhanced sealing, and using hard metal for increased durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the clamping plate is configured in one piece with the base body to simplify structure, then device complexity is reduced, but manufacturing precision deteriorates due to edge radius preventing precise fitting
Solution Approach 1:
The clamping plate is divided into two separate parts: a first clamping plate connected to the base body and a second clamping plate that can be adjusted independently. This segmentation allows each plate to be optimized separately - the first plate provides structural support while the second plate achieves precise fitting with the nozzle body, resolving the contradiction between structural simplicity and fitting precision.
2Productivity
If the application channel widens in the first spatial direction to produce a wide spray jet, then productivity is improved, but strength deteriorates due to narrowing in the second spatial direction
Solution Approach 1:
The application channel is designed with different cross-sectional characteristics in different regions: it widens in the first spatial direction (x-direction) to produce a wide spray jet for high productivity, while maintaining sufficient thickness in the second spatial direction (y-direction) to ensure mechanical strength. This local differentiation of geometric properties allows simultaneous optimization of both productivity and structural integrity.

AI summary
An application nozzle for applying a viscous material to workpieces has a nozzle body, through which an application duct extends from a material inlet to a material outlet. The nozzle body has, in a first spatial direction, a width greater than a thickness in a second spatial direction perpendicular to the first direction. The application channel widens towards the outlet in the first direction. A nozzle holder has a main body and two clamping plates. A material feed duct extends through the main body, leading into the inlet at a feed opening. The clamping plates, bearing on opposite nozzle body side faces, fix the nozzle body releasably to the main body. The clamping plates are separate components fixed releasably to the main body and the nozzle body, and/or the nozzle body has two nozzle plates bearing flat against one another, with at least one duct portion between the nozzle plates.
