Bag Making Apparatus Corner Cut Device Baffle Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag making apparatuses struggle to apply corner cutting processes to plastic bags with functional parts on the end face without compromising the functional elements, as conventional corner cutting methods often cut these features.
Innovation Solution
A bag making apparatus with a corner cut device that includes a cutter and a baffle plate to prevent cutting the base part of the first sheet panel, allowing for precise corner cut formation on plastic bags with protruding parts by folding and heat-sealing the sheets in a specific manner, ensuring the functional parts remain intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner cutting is applied to the end face part using conventional methods, then corner cut parts are formed to improve safety, but functional parts on the end face are also cut and damaged
Solution Approach 1:
The sheet panel is divided into different functional zones: a base part containing the functional part, and a folded part forming the end face. The corner cutting is applied only to the folded part while the base part remains intact, achieving segmentation of the cutting operation to protect functional elements.
Solution Approach 2:
A baffle plate is introduced as an intermediary component between the cutter and the base part. The baffle plate prevents the cutter from reaching and damaging the functional part on the base part, while allowing corner cutting to proceed on the folded part.
2Ease of manufacture
If the sheet panel is folded and heat-sealed to form the end face, then the structure is suitable for corner cutting, but the functional part on the base part is at risk of being cut
Solution Approach 1:
The baffle plate serves as a protective intermediary that physically blocks the cutter from contacting the base part containing the functional element. This allows the folded structure to be manufactured with corner cuts while protecting the functional part from damage.
Solution Approach 2:
The sheet panel is pre-folded and heat-sealed to create the end face structure before corner cutting is applied. The baffle plate is positioned in advance to define the cutting boundary, ensuring the functional part is protected during the subsequent corner cutting operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the creation of plastic bags with corner cut parts on the end face while preserving functional elements like protruding parts, enhancing safety and functionality by preventing the cutting of base parts during the corner cutting process.
Implementation Method 1
the first sheet panel is folded along a first fold line on a side of a side edge thereof to form a first folded part therein, such that the second sheet panel is folded along a second fold line
Implementation Method 2
heat-seals the first and second sheet panels in the longitudinal direction of the first and second sheet panels
Implementation Method 3
cut the second sheet panel and the folded-back part to form corner cut parts

AI summary
A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.
