Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple extrusion head systems for blow molding machines are complex to clean and produce, particularly when distributing plastic masses to extrusion heads arranged in a single plane, limiting flexibility and efficiency.
Innovation Solution
A multiple extrusion head design featuring distributing devices in multiple planes, allowing for uniform distribution to extrusion heads arranged in rows and planes, with channels that can be continuously produced and easily cleaned, and enabling flexible cross-sectional shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If channels are manufactured as bores closed by plugs, then the distributing device can supply multiple extrusion heads, but the production process becomes complicated and cleaning becomes difficult
Solution Approach 1:
The distributing device is divided into multiple separate distributing devices, each responsible for a specific plane of extrusion heads. This segmentation allows each device to be simpler to manufacture without plugs, while collectively supplying multiple extrusion heads across different planes.
Solution Approach 2:
The patent transitions from supplying extrusion heads in a single plane to supplying heads arranged in multiple planes (first plane, second plane, etc.). This dimensional expansion allows the distributing device to serve more extrusion heads while maintaining simpler channel structures that are easier to manufacture and clean.
2Productivity
If channels are manufactured as bores closed by plugs, then the distributing device can distribute mass, but cleaning during system stoppage becomes complicated
Solution Approach 1:
By dividing the distributing device into separate units corresponding to different planes, each unit can be independently cleaned. The channels are designed as continuous passages without plugs, allowing cleaning tools to access all areas easily during system stoppage.
Solution Approach 2:
Instead of creating closed bores that require disassembly for cleaning, the patent uses open continuous channels that are accessible for cleaning from the outside. This inverts the design approach from enclosed to open structures, facilitating easier maintenance.
3Device complexity
If extrusion heads are arranged in one plane, then the distributing device is simpler, but flexibility in arrangement is limited
Solution Approach 1:
The patent extends the arrangement from a single plane to multiple planes (first plane with first extrusion heads, second plane with second extrusion heads, etc.). This allows flexible spatial arrangement of extrusion heads while the distributing devices are designed specifically for each plane, maintaining reasonable complexity.
Solution Approach 2:
Each distributing device is designed to handle a specific plane of extrusion heads, creating a modular system where similar distributing devices can serve different planes. This multi-planar approach provides universal applicability while maintaining individual simplicity.

AI summary
A multiple extrusion head (1) for blow molding extrusion machines has a plurality of first extrusion heads (2) fixedly arranged side by side in a first row forming a first plane (3). A plurality of second extrusion heads (4) are fixedly arranged side by side in a second row forming a second plane (5) that extends parallel to the first plane (3). Per row, distributing devices (6, 6a, 6b) are provided with first distributing channels (7, 10) that are arranged in the first plane (3) and the second plane (5), respectively. The distributing devices (6a, 6b) are separated in the region of the first plane (3) and second plane (5), A third distributing device (15) is provided with third distributing channels (18) that are arranged in a third plane (16) extending at a right angle relative to the first plane (3) and to the second plane (5).
