Blister Box Pusher Guide Rail Weight Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing material pushing apparatus of blister boxing machines is noisy and has a short chain service life due to the chain bearing the weight and pulling the entire material pushing unit, leading to increased noise and reduced durability.
Innovation Solution
The apparatus features annular guide rails on both sides of the push plate guide rail, with movable sliding bases that bear the weight of the material pushing unit, allowing the chain to only pull the unit, reducing noise and prolonging the chain's service life. Additionally, an adaptive member connects the material pushing base to the chain, and adjustable guide grooves and rail change assemblies facilitate height adjustments and prevent wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the chain bears the weight and pulls the entire material pushing unit, then the material pushing unit can be moved along the annular track, but the noise increases and the chain service life decreases
Solution Approach 1:
The patent introduces guide rails as an intermediary structure between the chain and the material pushing unit. The guide rails bear the weight of the material pushing unit, while the chain only provides the pulling force to move it along the annular track. This separation of functions reduces the load on the chain, thereby decreasing noise and extending service life.
2Device complexity
If the chain bears the weight of the material pushing unit, then the structure can be simplified, but the chain wear increases and noise increases
Solution Approach 1:
The patent segments the functional responsibilities between the guide rails and the chain. The guide rails are responsible for supporting the weight and providing guidance, while the chain is responsible only for propulsion. This functional segmentation allows each component to be optimized for its specific role, reducing overall wear and improving reliability.
3Power
If the chain pulls the entire material pushing unit including its weight, then the driving force requirement is reduced, but the chain noise increases and service life decreases
Solution Approach 1:
The guide rails act as a mediator that supports the weight of the material pushing unit, allowing the chain to focus solely on providing the pulling force for movement. This reduces the power requirement for the chain while simultaneously decreasing noise and extending service life.
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
This design significantly reduces noise and extends the chain's service life by distributing the weight to the guide rails, while enabling efficient height adjustments and reducing wear on push plate and paper rollers, thereby improving the overall operation and longevity of the system.
Implementation Method 1
the annular guide rail is in a form of groove, the movable sliding base is a roller and the movable sliding base rolls in the groove
