Pneumatic Adhesive Granulate Feed for Edge Banding Glue Pots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge banding machines face challenges in efficiently and conveniently changing adhesive colors in the glue pot, leading to prolonged downtimes due to the need to completely remove old adhesive residues and the risk of glue caking, with no simple solution for precise glue pot filling.
Innovation Solution
A pneumatically operated glue pot filling device that uses compressed air or negative pressure to convey adhesive granulate from a storage container to the glue pot, featuring a conveying line, filling nozzle, and control unit to manage adhesive flow and prevent cooling of molten adhesive, allowing for precise filling and easy color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If adhesive granulate is stored in the glue pot for extended periods, then adhesive availability is maintained, but adhesive caking occurs on side walls and quality deteriorates
Solution Approach 1:
The invention extracts the adhesive granulate from the glue pot storage and transfers it to a separate storage container. This separation allows the adhesive to be stored without causing caking in the glue pot, while still maintaining availability when needed through on-demand pneumatic transfer.
Solution Approach 2:
The invention introduces a pneumatic conveying system as an intermediary between the storage container and the glue pot. This intermediary mechanism enables controlled transfer of adhesive granulate only when needed, preventing continuous storage in the glue pot that would lead to caking and quality degradation.
2Manufacturing precision
If the glue pot is completely emptied and cleaned when changing adhesive colors, then color change quality is maintained, but downtime increases and productivity decreases
Solution Approach 1:
The invention segments the adhesive storage and delivery system into separate components: a storage container holding the adhesive granulate and a glue pot receiving it only when needed. This segmentation allows for easy color changes by simply changing the storage container without requiring complete emptying and cleaning of the glue pot, thus maintaining color consistency while reducing downtime.
Solution Approach 2:
The invention prepares adhesive granulate in advance in the storage container in the required color before it is needed in the glue pot. This preliminary preparation allows for quick color changes by simply replacing the storage container rather than cleaning the entire system, thereby maintaining color consistency and reducing machine downtime.
3Quantity of substance
If adhesive granulate is transferred to the glue pot in large quantities, then sufficient adhesive is available for operation, but heat exposure increases and physical changes occur
Solution Approach 1:
The invention applies partial action by transferring only the necessary amount of adhesive granulate from the storage container to the glue pot at a time, rather than transferring large quantities. This partial transfer approach ensures sufficient adhesive is available for the current operation while minimizing heat exposure and physical changes to the adhesive.
