Lamination Device Belt Pre-Heating Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamination devices require pre-heating before use, leading to inefficient thermal sealing if the device is turned on immediately.
Innovation Solution
The lamination device incorporates heater members surrounded by transmission belts, with pre-heat pieces that conduct heat to the belts and the object to be laminated, allowing for effective pre-heating and thermal sealing without prior device activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional thermal sealing is used with heaters beside rollers, then thermal sealing function is achieved, but pre-heating time is required and sealing speed is slow
Solution Approach 1:
The patent applies preliminary action by incorporating pre-heat pieces that wrap around the heating elements. These pre-heat pieces are positioned to contact the object before it reaches the main heating zone, performing preliminary heating in advance. This allows the object to arrive at the sealing zone already warmed, eliminating the need for prolonged pre-heating of the entire device and significantly reducing the pre-heating time requirement.
Solution Approach 2:
The heating system is segmented into distinct functional zones: pre-heat pieces for initial warming and main heating elements for final sealing. This segmentation allows each component to perform its specific function efficiently, with pre-heat pieces handling the initial temperature rise and heating elements completing the sealing process, thereby increasing overall sealing speed without requiring the entire device to be pre-heated.
2Ease of operation
If heaters are activated immediately without pre-heating, then device readiness is improved, but thermal sealing quality deteriorates
Solution Approach 1:
The pre-heat pieces perform preliminary heating action on the object immediately when it contacts the heating zone, eliminating the need for advance device pre-heating. This allows the device to be ready for immediate use while ensuring the object receives sufficient heat treatment for quality sealing, as the pre-heat pieces directly transfer heat to the object rather than requiring the entire device to reach operating temperature first.
Solution Approach 2:
The patent applies local quality by concentrating heating action precisely where needed - the pre-heat pieces are positioned to contact only the specific portions of the object requiring initial warming. This localized heating approach ensures that sealing quality is maintained by delivering heat exactly where required, while allowing the rest of the device to remain at ambient temperature, thus improving ease of operation without compromising sealing reliability.
3Use of energy by moving object
If heating elements directly contact the object, then heating efficiency is improved, but temperature control becomes difficult
Solution Approach 1:
The pre-heat pieces serve as intermediaries between the heating elements and the object. They wrap around the heating elements and contact the object, mediating the heat transfer process. This intermediary layer maintains high heating efficiency by ensuring direct thermal contact, while simultaneously providing temperature control by acting as a heat distribution medium that prevents localized overheating and ensures uniform heat transfer to the object surface.
