Compression Pin Assembly for Vibratory Screen Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibratory screening machines face challenges in securely attaching screens due to high compression forces required, which can be difficult to activate manually and pose safety risks, and existing solutions do not allow for adjustable compression levels.
Innovation Solution
A compression assembly system with multiple compression pins and adjustable pin assemblies that distribute energy across multiple assemblies, allowing for increased compression force with reduced activation energy, and providing a single locking position for secure attachment and easy adjustment of compression forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high compression force is applied to secure the screen, then the screen attachment reliability is improved, but the activation energy required increases and manual operation becomes difficult
Solution Approach 1:
The compression assembly is divided into multiple segments including a body, handle, and spring mechanism. The spring is segmented into coils that progressively store and release energy. This segmentation allows the system to accumulate compression force over the compression stroke rather than requiring instantaneous high energy input, resolving the contradiction between reliable attachment and manageable activation energy.
Solution Approach 2:
The spring mechanism performs preliminary energy storage during the compression stroke when the handle is depressed. The spring coils progressively store mechanical energy as they compress, preparing the force needed for secure screen attachment in advance. This preliminary action eliminates the need for instantaneous high energy input during activation, allowing manual operation while maintaining reliable attachment.
2Adaptability or versatility
If fixed compression force is used, then the device structure is simplified, but the adaptability to different screen sizes and compression needs is reduced
Solution Approach 1:
The compression assembly incorporates a dynamic adjustment mechanism where the spring preload can be modified by rotating the handle to different positions. This creates a continuously variable compression force rather than fixed discrete settings. The dynamic adjustment allows adaptation to different screen sizes and compression requirements while maintaining a relatively simple single-assembly structure, resolving the contradiction between adaptability and device complexity.
3Ease of operation
If multiple compression assemblies are used to distribute energy, then the activation energy per assembly is reduced, but the device complexity increases
Solution Approach 1:
Multiple spring mechanisms are merged into a single integrated compression assembly where the springs work together in parallel within one structural unit. This combining approach distributes the energy storage and compression function across multiple spring elements while maintaining a unified structure that operates as a single mechanism. The result is reduced activation effort per assembly while avoiding the complexity of multiple separate assemblies, resolving the contradiction between ease of operation and device complexity.

AI summary
Embodiments of the present disclosure provide for systems, apparatuses, and methods of securing screen assemblies. Embodiments include a system having a compression assembly with a compression pin and a pin assembly having a pin. The compression assembly may be attached to a first wall member of a vibratory screening machine and the pin assembly may be attached to a second wall member of the vibratory screening machine opposite the first wall member such that the compression assembly is configured to assert a force against a first side portion of a screen assembly and drive a second side portion of the screen assembly against the pin of the pin assembly. The pin assembly may include a pin that is internally or externally mounted and that is adjustable and/or replaceable.
