Parallel Compaction Ejection Press for Compactable Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compacting presses for materials are sequential in operation, limiting the duration of compaction, ejection, and binding processes, as strapping can only occur after complete ejection and retraction, which restricts productivity.
Innovation Solution
Decoupling compaction and ejection processes allows for independent operation, enabling strapping during ejection and parallel preparation for the next compaction cycle, with distinct axes for compaction, transfer, and ejection, and the use of hydraulic pistons for efficient thrust generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sequential compaction and ejection process is used, then the structure is simple, but the productivity is limited due to sequential operation
Solution Approach 1:
The press is divided into independent functional modules: compaction means with compaction means, transfer means, and ejection means. Each module operates independently along its own axis, allowing parallel execution of compaction, transfer, and ejection operations, thereby increasing productivity without excessive complexity
Solution Approach 2:
The invention introduces multiple spatial dimensions for different operations: compaction occurs along a first axis, transfer along a second axis, and ejection along a third axis. This multi-dimensional arrangement enables simultaneous operations in different directions, resolving the productivity-complexity contradiction
2Loss of time
If strapping occurs after complete ejection and retraction, then the operation is simple, but the processing time is extended
Solution Approach 1:
The strapping operation is performed in advance during the ejection phase rather than waiting for complete compaction and retraction. The binding device applies straps to the compacted material while it is being ejected, overlapping operations to reduce total cycle time
Solution Approach 2:
The press maintains continuous operation by overlapping the compaction cycle with the ejection and strapping cycle. While one block is being compacted, the previous block is being ejected and strapped simultaneously, eliminating idle time and reducing overall processing time
3Ease of repair
If the compaction axis and ejection axis are aligned, then the structure is compact, but the maintenance access is difficult
Solution Approach 1:
The invention positions the ejection axis perpendicular to the compaction axis, utilizing a different spatial dimension. This orthogonal arrangement provides clear access paths for maintenance personnel and equipment to reach internal components without increasing the overall footprint excessively

Implementation Method 1
the compaction means and the ejection means each comprise a piston and a thrust block, respectively called the compaction block and the ejection block, the piston driving the compaction block and the piston driving the ejection block each being connected to a separate hydraulic pressure line
