Solution Overview
Problem
Existing bag sealing machines either have a constant and limited sealing length or lack vacuum functionality, making them incompatible for sealing long bags.
Innovation Solution
A bag sealing machine with a machine head for hot melt sealing and a machine body for vacuumizing, featuring a roller mechanism, heat generating module, upper and lower sealing rings, and a lifting mechanism that allows for adjustable sealing length and automatic vacuumization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sealing length is extended to accommodate long bags, then the adaptability is improved, but the vacuum function is lost
Solution Approach 1:
The sealing mechanism is divided into two independent parts: an upper sealing unit with a heating element for hot melt sealing, and a lower sealing unit with a vacuum hole for vacuumizing. These two units can operate independently or in combination, allowing the machine to seal bags of any length while maintaining vacuum functionality for shorter bags.
Solution Approach 2:
The lower bin is designed to move vertically relative to the upper bin through a lifting mechanism. This dynamic adjustment allows the distance between the upper and lower sealing units to be changed, enabling the machine to accommodate bags of different lengths and switch between sealing-only mode and sealing-plus-vacuum mode.
2Device complexity
If a fixed sealing mechanism is used, then the device complexity is reduced, but the sealing length is limited
Solution Approach 1:
The lower bin is designed to move vertically relative to the upper bin through a lifting mechanism. This dynamic adjustment allows the distance between the upper and lower sealing units to be changed, enabling the machine to accommodate bags of different lengths while maintaining vacuum functionality for shorter bags.
3Device complexity
If manual operation is required for sealing, then the device complexity is reduced, but the productivity is lowered
Solution Approach 1:
A detection switch is installed to automatically detect when a bag is present in the sealing position. When the switch detects the bag, it automatically triggers the sealing and vacuumizing processes, eliminating the need for manual operation and improving productivity while maintaining simple device structure.

AI summary
The present invention relates to the technical field of sealing devices, for solving the technical problem that sealing and vacuumizing are incompatible when the sealing length of the bag is too long, and discloses a bag sealing machine, the machine head includes an upper bin, a roller for driving the bag to move and a heat generating module cooperating with the roller to seal the bag are arranged in the upper bin. An upper sealing ring is arranged at an outer side of a groove of the upper bin. A lower bin is arranged in the machine body, a vacuum hole is defined in the lower bin, and a lower sealing ring corresponding to the upper sealing ring is arranged at an outer side of a groove of the lower bin. A lifting mechanism for driving the lower bin to move up and down is provided in the machine body.
