Shot Processing Machine Door Adhesion Prevention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shot blasting machines, projection material adheres to the door inside the projection chamber and spills over when opened, causing material to drop outside the cleaning chamber during the loading and discharging process.
Innovation Solution
A shot processing machine is designed with a projection material adhesion prevention mechanism on the door's interior surface, including angled surfaces on fixing members and an agitating mechanism with an L-shaped agitating belt, along with seal members and a control section to manage the door's opening and closing, ensuring projection material is contained within the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is opened to remove processed workpieces, then workpiece discharge is enabled, but projection material spills over and drops outside the cleaning chamber
Solution Approach 1:
A receiving plate is introduced as an intermediary component between the door and the external environment. The receiving plate captures projection material that spills over when the door is opened, preventing it from dropping outside the cleaning chamber. This mediator component solves the contradiction by allowing the door to open for workpiece discharge while intercepting the harmful projection material spill.
2Quantity of substance
If projection material accumulates on the door surface, then adhesion occurs, but material spills over when the door opens
Solution Approach 1:
The invention converts the harmful effect of projection material accumulation on the door surface into a beneficial controlled spill. By designing the door opening trajectory and positioning the receiving plate strategically, the accumulated material is guided to spill onto the receiving plate rather than outside the chamber. This transforms the harmful uncontrolled spill into a controlled deposition on the receiving plate.
3Object-generated harmful factors
If the door is kept closed to prevent material spill, then projection material is contained, but workpiece loading and discharging cannot be performed
Solution Approach 1:
The receiving plate serves as a mediator that enables the door to remain open for workpiece operations while maintaining projection material containment. The plate intercepts spilled material, allowing the door to be open without causing external contamination, thus resolving the contradiction between door openness for operations and material containment.
