Heat Sealer Module Segmentation for Vacuum Packaging

The vacuum chamber is divided into a first chamber and a second chamber separated by a partition wall. The first chamber receives the bag-shaped package for evacuation, while the second chamber houses the heating element. This segmentation allows the system to achieve effective gas evacuation without requiring a single large complex chamber, thus improving productivity while managing apparatus complexity.

A partition wall with a through-hole acts as an intermediary structure between the first and second chambers. This intermediary element enables thermal coupling between chambers while maintaining their functional separation, allowing efficient gas evacuation through the heating element without direct contact between the package and heating source.

By segmenting the vacuum chamber into two smaller interconnected chambers rather than using one large chamber, the system can accommodate larger products through the combined volume while maintaining smaller individual chamber dimensions. This preserves component durability and process reliability as the heating element and vacuum pump do not need to service an excessively large volume.

The first chamber is effectively nested within the overall vacuum system architecture, with the second chamber containing the heating element. This nested arrangement allows the system to scale for larger products while keeping critical components within manageable size limits, maintaining reliability.

The patent replaces the traditional mechanical sealing bar system with a thermal sealing approach using a heating element in the second chamber. The heating element thermally softens and seals the package material without requiring complex mechanical pressing mechanisms, thus maintaining sealing capability while reducing device complexity.

The vacuum pressure differential created by the vacuum pump in the first chamber provides the force necessary to press the package material against the heating element for sealing. This pneumatic pressure substitution eliminates the need for complex mechanical sealing bar actuation systems.

The partition wall with through-hole acts as a thermal intermediary, allowing controlled heat transfer from the heating element in the second chamber to the package material in the first chamber. This intermediary structure enables sufficient sealing temperature while preventing direct exposure to excessive heat that would cause material degradation.

The heating element provides localized heating precisely where needed at the package sealing location, rather than heating the entire vacuum chamber. This local quality approach ensures adequate sealing temperature at the seal point while keeping overall temperatures low enough to prevent material degradation and contamination.
