Retractable Baffle and Lifting Plate for Flexible Box Side Tongue Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic packaging machines are inefficient and unstable when handling flexible materials like disposable gloves and masks, as traditional sealing methods often cause deformation and damage, and lack a reliable mechanism for accurately positioning and supporting side tongues for secure closure.
Innovation Solution
The implementation of a retractable positioning baffle mechanism and a lifting entity supporting insertion plate, combined with a low-friction pressing head mechanism, allows for precise alignment and buckling of side tongues, ensuring accurate positioning and stable closure without damaging the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sealing methods (lock, adhesive, positive sealing) are used on flexible materials, then the packaging process can be completed, but the box deforms and damages during transportation due to material resilience and expansion
Solution Approach 1:
The patent employs dynamic mechanisms including retractable positioning baffles that can extend and retract, lifting entity supporting insertion plates that move vertically, and pressing heads that apply controlled force. These dynamic components adapt to the flexible material's movement and expansion during packaging and transportation, maintaining box integrity while enabling automated packaging operations
Solution Approach 2:
The positioning baffle mechanism performs preliminary positioning of the box and side tongues before the sealing operation. The lifting entity supporting insertion plate pre-positions the side tongues in the correct orientation, and the pressing head pre-applies positioning pressure to ensure proper alignment before final sealing, preventing deformation during subsequent handling
2Productivity
If traditional sealing methods are used, then packaging can be completed, but customs inspection requires destructive disassembly which wastes qualified goods
Solution Approach 1:
The patent segments the sealing structure into multiple independent components: the box body, side tongues with slots, lifting entity supporting insertion plates, and positioning baffles. This segmentation allows the side tongues to be buckled together to form an interlocking structure that maintains box integrity while enabling non-destructive opening for customs inspection
3Reliability
If manual packaging is used to avoid deformation, then box quality is maintained, but packaging efficiency is low
Solution Approach 1:
The positioning baffle mechanism and lifting entity supporting insertion plate work together in an automated sequence where the insertion plate lifts the side tongues into position, the positioning baffle ensures correct alignment, and the pressing head applies controlled pressure to buckle the tongues together. This self-coordinating automated system maintains box quality while achieving high packaging efficiency
