Splicing Punch Air Suction Layout for Corrugated Tape Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing splicing machines for insulating panels are bulky and expensive, with inefficient air suction systems that hinder vertical compactness and tape adhesion on corrugated surfaces, leading to suboptimal waste minimization and panel continuity.
Innovation Solution
A compact splicing machine with a punch and manifold featuring a horizontal internal cavity and sequential air control via valve members, allowing controlled air suction to adhere tape to the punch surface one portion at a time, and a tape dispenser with anti-friction clamps for easy detachment, enabling efficient tape application on corrugated surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air suction system is developed on the upper frame of the machine, then the tape can be drawn onto the punch, but the vertical compactness of the machine is limited
Solution Approach 1:
The air suction system is repositioned from the upper frame to the lower frame of the machine. The manifold is mounted on the lower frame with its cavity extending horizontally, and air suction holes are provided in the punch at the lower frame level. This spatial reconfiguration maintains tape adhesion functionality while improving vertical compactness.
2Ease of operation
If complicated network of flexible hoses is used to convey air, then sequential tape drawing is possible, but the system becomes cumbersome
Solution Approach 1:
The complex network of flexible hoses is replaced by a simplified rigid manifold structure mounted on the lower frame. The manifold contains internal cavities and passages that directly channel air to the punch holes, eliminating the need for complicated flexible hose connections while maintaining sequential air delivery capability.
Solution Approach 2:
The air conveyance function is integrated into the machine frame structure itself through the manifold assembly. The manifold is directly coupled to the punch, merging the air delivery system with the structural framework and eliminating separate hose connections.
3Productivity
If tape is drawn all at once onto the punch, then the process is faster, but the tape cannot lie evenly on the corrugated surface
Solution Approach 1:
The air suction system operates in a sequential periodic manner, activating different groups of air suction holes in successive time intervals. The controller activates first group holes, then second group holes, and finally third group holes in sequence. This periodic activation pattern allows the tape to be drawn progressively onto the corrugated surface, ensuring even adhesion while maintaining efficient processing speed.
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
The machine reduces waste and enhances panel continuity by ensuring proper tape adhesion on corrugated surfaces, improving operational efficiency and reducing machine size through vertical compactness and precise air management.
Implementation Method 1
the air suction system for attaching the tape to the corrugated punch develops on the upper frame of the machine
Implementation Method 2
the air is conveyed to the punch from the top by means of a complicated and cumbersome network of flexible hoses, because it is necessary to draw the tape onto the punch not all at once but sequentially, one portion at a time

AI summary
A splicing machine (MC) is described for making insulating panels. The machine joins two ends of sheet metals with a deposited tape and comprises- a punch (10) having a supporting surface (S) for the ends of sheet metal to be spliced, a manifold (20) directly coupled to the punch (10) and comprising an internal cavity (22) which at one end comprises a connection to an air passage (24), a plurality of valve members (26) placed inside the cavity (22), a tape dispenser (60) for laying a splicing tape on the supporting surface. By controlling the valve members air is sucked from the holes in the supporting surface (S).
