Solution Overview

Problem

Current paper box forming apparatuses require manual operation for folding and sealing, leading to high labor intensity and low production efficiency, especially when forming boxes with turnover covers, as they struggle to ensure sequential folding and adhesion of side walls during the bending process.

Innovation Solution

A paper box package forming apparatus featuring a continuous feeding device, box folding mechanism, and cover sealing mechanism, which includes a paperboard stacking frame, adsorption mechanism, roll extrusion conveying mechanism, downward-pressing inner punch, box folding outer mold, and cover sealing mechanism, allowing for automatic folding and sealing of paper boxes with reduced manual intervention and increased efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual operation is used for folding and sealing paper boxes, then the device structure can be simple, but the labor intensity is high and production efficiency is low

Engineering Contradiction:
Improveproduction efficiencyVSAvoiddevice structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The paper box forming process is divided into distinct functional modules: a feeding device with paperboard stacking frame and adsorption mechanism, a box folding device with inner punch and outer mold, and a cover sealing mechanism. Each module independently handles a specific operation, enabling automated continuous production while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If pre-bending devices are added to ensure sequential folding of side walls, then the forming yield improves, but the device complexity increases

Engineering Contradiction:
Improveforming yieldVSAvoiddevice structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The paperboard is pre-cut with fold lines and pre-scored at the ear portions before entering the forming apparatus. This preliminary preparation allows the main forming device to complete sequential folding in a single operation cycle without requiring additional pre-bending equipment, thereby maintaining high forming yield while avoiding increased device complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The outer mold of the box folding device serves as an intermediary structure that guides and constrains the folding sequence. The outer mold's geometric features, including guide surfaces and positioning elements, ensure that side walls fold in the correct sequence during the pressing operation, achieving high forming yield without complex control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the inner mold punch presses down to form the box, then the box can be formed, but the inner mold punch conflicts with the pre-folded portion

Engineering Contradiction:
Improveforming speedVSAvoidforming reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The inner punch and outer mold are designed with staggered vertical positioning. The outer mold extends higher than the inner punch in certain regions, creating a vertical dimension hierarchy that allows the inner punch to press down without colliding with pre-folded portions that are contained within the outer mold's higher boundaries. This dimensional arrangement enables reliable high-speed forming.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If automatic cover sealing is implemented, then the labor intensity decreases, but the device complexity increases

Engineering Contradiction:
Improvelabor intensityVSAvoiddevice structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cover sealing mechanism is merged with the existing box folding device structure. The sealing function is integrated into the same press station where the box body is formed, utilizing the downward pressing motion already present in the system. This integration automates cover sealing without requiring a completely separate sealing machine, thereby reducing labor intensity while limiting the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A paper box package forming apparatus includes a continuous feeding device, a box folding mechanism and a cover sealing mechanism. The continuous feeding device includes a paperboard stacking frame, an adsorption mechanism and a roll extrusion conveying mechanism. A paperboard is absorbed from a back side of the paperboard stacking frame through the adsorption mechanism and conveyed to a box folding device through the roll extrusion conveying mechanism. The box folding device includes a downward-pressing inner punch, a box folding outer mold and a pushing mechanism. The pushing mechanism conveys a bottom box to the cover sealing mechanism. The downward-pressing and attaching mechanism includes downward-pressing driving mechanism, a top-pressing plate, side-pressing plates and overturning cylinders. The side-pressing plates are hinged to side edges of the top-pressing plate through the driving of the overturning cylinders.
