Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing film packaging machines are limited in producing bubble wrap in continuous operation and are often complex and bulky, unable to directly utilize air cushion films for packaging goods.
Innovation Solution
A film packaging machine equipped with a conveyor device, cross-cut welding device, and longitudinal cutting welding devices, featuring an air cushion film production system that produces bubble films from two film webs in continuous operation using welding roller devices with heating mechanisms, allowing for direct integration into the packaging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air cushion films are produced in advance using traditional methods, then the films can be used for packaging, but the production process is not continuous and the equipment is complex and bulky
Solution Approach 1:
The patent combines the air cushion film production system directly with the film packaging machine by integrating the welding roller device into the film feeding mechanism. This merging allows the bubble wrap to be produced continuously in-line with the packaging process, eliminating the need for separate production equipment and achieving both continuous operation and simplified device structure.
Solution Approach 2:
The welding roller device enables continuous production of air cushion films by continuously welding two film webs together as they pass through the device. The heating element maintains constant temperature to ensure uninterrupted welding, and the roller mechanism continuously feeds and seals the films, achieving non-stop production without manual intervention or batch processing.
2Adaptability or versatility
If traditional film packaging machines are used, then packaging can be performed, but they cannot directly utilize air cushion films produced in continuous operation
Solution Approach 1:
The film packaging machine is designed with multi-functionality by incorporating the welding roller device that can process air cushion films specifically. The device can handle both traditional films and bubble wrap materials, making the machine versatile for different packaging needs while enabling continuous operation through the integrated film production and packaging capabilities.
3Productivity
If complex equipment is used to produce bubble wrap, then continuous production is possible, but the machine becomes bulky and difficult to operate
Solution Approach 1:
By merging the air cushion film production system with the film packaging machine, the patent eliminates the need for separate bulky equipment. The welding roller device is integrated into the existing packaging machine structure, combining multiple functions (film welding, feeding, and packaging) into a single compact unit that is easier to operate and less space-consuming.
