Infusion Capsule Filter Forming Machine With Automated Reciprocating Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for forming filters in infusion capsules suffer from soiling due to material release during the forming process, leading to inadequate cleaning that requires significant downtime and labor, and is not effectively addressed by manual methods.
Innovation Solution
A machine with integrated cleaning devices featuring reciprocating linear motion cleaning elements that move between disengagement and cleaning positions, allowing for rapid and effective cleaning of forming surfaces without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual cleaning is performed on forming devices, then cleaning can be done with simple equipment, but cleaning time is long and machine downtime is high
Solution Approach 1:
The forming device performs its own cleaning through integrated cleaning elements (brushes or scarifiers) that are automatically actuated during the forming cycle, eliminating the need for separate manual cleaning operations and reducing machine downtime
Solution Approach 2:
The cleaning operation is integrated into the continuous forming cycle, allowing cleaning to occur during idle periods or between forming operations without interrupting the overall production flow, thus maintaining continuous useful action
2Ease of operation
If manual cleaning is performed on forming devices, then labor requirements are reduced, but cleaning quality is inadequate and time-consuming
Solution Approach 1:
The forming device automatically cleans itself using integrated cleaning elements that are positioned and actuated during the forming cycle, ensuring consistent cleaning quality without manual intervention
Solution Approach 2:
The cleaning elements are actuated periodically during the forming cycle (e.g., during idle periods or between operations) to maintain consistent cleaning quality through repeated automated action
3Reliability
If cleaning elements are always in contact with forming devices, then cleaning is continuous, but interference with normal machine functioning occurs
Solution Approach 1:
The cleaning elements are designed to be movable, transitioning between an engaged position during idle periods and a disengaged position during active forming operations, allowing the system to adapt dynamically to operational requirements
Solution Approach 2:
The cleaning elements are activated periodically during the forming cycle rather than continuously, engaging during idle periods and disengaging during active operations to prevent interference while maintaining cleaning consistency
