Pivoting Hold-Down Device for Packaging Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging structures often slip and move during evacuation and sealing steps in packaging processes, leading to incorrect sealing and damage to packaging apparatuses, due to excessive force exerted on hold-down devices, which can cause springs to bend or break.
Innovation Solution
A pivoting hold-down device that rotates about its longitudinal axis, increasing pressure and grip on packaging structures, reducing the reliance on springs and minimizing damage to the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hold-down device uses springs to apply force on packaging structures, then the packaging structure can be held in place, but the springs can bend or break due to excessive force during evacuation and sealing steps
Solution Approach 1:
The hold-down device incorporates a pivoting mechanism that allows the device to dynamically adjust its position and apply force in response to packaging pull-back during evacuation and sealing. This dynamic adjustment prevents excessive force transmission to the springs, resolving the contradiction between maintaining reliable holding and preventing spring damage.
Solution Approach 2:
The pivoting mechanism acts as an intermediary between the packaging structure and the springs, absorbing and redistributing the forces generated during packaging operations. This intermediary mechanism protects the springs from direct exposure to excessive forces while maintaining effective holding of the packaging structure.
2Reliability
If excessive force is exerted on hold-down devices during evacuation and sealing, then the packaging structure can be securely held, but the packaging structure can slip and move leading to incorrect sealing
Solution Approach 1:
The pivoting hold-down device dynamically responds to packaging pull-back by rotating about its longitudinal axis, maintaining optimal contact pressure on the packaging structure throughout the evacuation and sealing process. This dynamic adjustment ensures the packaging structure remains stable and prevents slipping, while avoiding excessive force that could cause damage.
3Ease of manufacture
If springs are used to couple the hold-down device to the packaging apparatus, then the device can be easily installed, but the springs are vulnerable to damage from excessive force
Solution Approach 1:
The pivoting mechanism provides a simple yet effective solution that maintains ease of assembly while protecting the springs. The pivot allows the hold-down device to move independently, absorbing forces that would otherwise damage the springs, thus resolving the contradiction between simple assembly and component durability.

AI summary
The present disclosure relates to a hold-down device for use in the packaging industry. For example, the hold-down may be used with an apparatus for manufacturing a package. The hold-down may be configured to retain a packaging structure during the evacuation and/or sealing steps of a packaging process. The hold-down may include an elongate member and an attachment assembly. The elongate member may be configured to pivot and/or rotate about its longitudinal axis in response to a force exerted on the packaging structure during an evacuation and/or sealing step of a packaging process.
