Solution Overview

Problem

Existing packaging machines require manual adjustment of rotating assembly axes to accommodate different film materials, which is time-consuming and inefficient.

Innovation Solution

A packaging machine with adjustable rotating assemblies that allow for automatic or manual adjustment of the relative position and orientation of the axes of rotation, enabling easy adaptation to films of varying thickness and material properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment of rotating assembly axes is used, then the machine can accommodate different film materials, but the adjustment process is time-consuming and inefficient

Engineering Contradiction:
Improveability to accommodate different film materialsVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements adjustable rotating assemblies where the axes of rotation can be dynamically repositioned relative to each other. The adjustment mechanism allows the second axis to be moved closer to or farther from the first axis, enabling adaptation to different film thicknesses and material properties without manual intervention during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the positional parameter of the rotating assembly axes to accommodate different packaging requirements. By adjusting the distance between the first and second axes of rotation, the system can optimize sealing and cutting operations for various film materials, transforming a fixed-parameter system into a variable-parameter one.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the axes of rotation are fixed in position, then the machine structure is simple, but the machine cannot adapt to films of varying thickness and material properties

Engineering Contradiction:
Improveadaptation to varying film thicknessVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic adjustability to the rotating assembly system. The second rotating assembly can be repositioned along the vertical direction to change the distance between axes, allowing the system to adapt to different film thicknesses while maintaining a relatively simple overall structure through controlled mobility rather than complete redesign.

Inventive Principle:
Principle #15Dynamics

3Productivity

If manual intervention is required for axis adjustment, then the structure remains simple, but the machine efficiency is reduced

Engineering Contradiction:
Improvemachine efficiencyVSAvoidautomation mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-adjusting capabilities where the rotating assemblies can be repositioned without continuous manual intervention. The adjustment mechanisms are designed to allow the system to adapt to different film materials autonomously, improving productivity by eliminating repeated manual adjustments while maintaining reasonable structural complexity through integrated adjustment features.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a packaging machine with a sealing and cutting assembly comprising two lateral frames (7.1, 7.2) facing each other; a first rotating assembly (1) with an axis of rotation (1.0) and an actuation tool (1.1) arranged between the lateral frames (7.1, 7.2) with possibility to rotate; a second rotating assembly (2) with an axis of rotation (2.0) and an actuation tool (2.1) arranged between the lateral frames (7.1, 7.2) with possibility to rotate; and a respective adjustment assembly (9) associated with each lateral frame (7.1, 7.2). Each adjustment assembly (9) comprises a lateral plate (9.0) associated with a lateral frame (7.1, 7.2) by means of a plate rotating shaft (9.00) with respect to which it can rotate. The second axis of rotation (2.0) is associated with the lateral plate (9.0) at a point not coincident with the plate rotating shaft (9.00).
