Vacuum Packaging Machine Detachable Contrast Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vacuum packaging machines face challenges in effective cleaning and sanitizing due to the non-removable contrast bars on the lid, which are prone to soiling from liquid and vapor deposition during the packaging process, making maintenance difficult and posing reliability and safety concerns.
Innovation Solution
A vacuum packaging machine with a detachable contrast bar using a quick coupling/uncoupling device, allowing for easy removal and reattachment, facilitating cleaning and maintenance, and featuring a profiled element with an elastically flexible contact body for sealing the vacuum bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contrast bar is mounted on the lid in a non-removable manner, then the sealing function is reliable, but the cleaning and sanitizing effectiveness deteriorates
Solution Approach 1:
The contrast bar is divided into a removable component that can be separated from the lid, allowing the lid to be cleaned independently while maintaining the sealing function when assembled. The quick coupling device enables easy segmentation and reassembly without compromising reliability.
Solution Approach 2:
The contrast bar transitions from a static non-removable mounting to a dynamic removable mounting system. The quick coupling device allows the contrast bar to be easily attached and detached, providing flexibility for cleaning while maintaining sealing reliability during operation.
2Device complexity
If the contrast bar is integrated in the body of the lid, then the structural simplicity is maintained, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
The contrast bar is segmented from the lid body, allowing it to be removed for cleaning while maintaining a simple overall structure. The quick coupling device provides a straightforward attachment mechanism that does not complicate the structural design.
Solution Approach 2:
The contrast bar is extracted as a separate removable component from the lid body, enabling easy cleaning and maintenance without requiring disassembly of the entire lid structure. This extraction maintains structural simplicity while improving maintainability.
3Strength
If the contrast bar is mounted with screws and adhesive elements, then the attachment strength is sufficient, but the ease of removal for cleaning deteriorates
Solution Approach 1:
The attachment mechanism transitions from a fixed permanent mounting to a dynamic removable mounting. The quick coupling device provides strong attachment during operation but enables easy removal for cleaning, combining strength with operational flexibility.
Solution Approach 2:
The contrast bar can be easily removed and reattached multiple times for cleaning purposes. The quick coupling device allows the contrast bar to be discarded from the lid for cleaning and then recovered by simple reattachment, facilitating maintenance without compromising attachment strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine provides improved cleaning and maintenance capabilities, ensuring reliability and safety while maintaining constructiveness and cost-effectiveness, as the detachable contrast bar allows for effective cleaning and easy operation.
Implementation Method 1
the heat-sealing bag is provided with an electric resistance heater and can move in the direction of the contrast bar, so as to be able to press the bag against the contrast bar, and allows to be able to seal it subsequently, by heat-sealing its sheets made of plastic material, as a consequence of the electric power supply of its electric resistance heater
Implementation Method 2
vacuum is created in the vacuum chamber by means of the activation of a vacuum pump
Implementation Method 3
a profiled element with an elastically flexible contact body for sealing the vacuum bags
