Vacuum Switching Valve Segmentation for CNC Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum switching valves in CNC machine tools are prone to blockages due to fine debris and dust, complicating maintenance and reducing production efficiency, as the entire negative pressure path needs to be closed for repairs.
Innovation Solution
A vacuum switching valve design featuring a movable valve element, stopper, and sealing rings that allows for isolation of the intake channel without closing the entire negative pressure path, enabling maintenance without disrupting the system's operation.

Engineering Contradiction Analysis
1Ease of repair
If the entire negative pressure path is closed for maintenance of the intake pipeline, then the blockage problem can be addressed, but production efficiency is reduced and the maintenance process becomes complicated
Solution Approach 1:
The negative pressure path is segmented into multiple independent sections. The intake pipeline is divided into a first intake pipeline section and a second intake pipeline section, allowing one section to be maintained while the other remains operational. This is achieved through separate valve control mechanisms that can isolate specific segments without shutting down the entire system.
Solution Approach 2:
The system employs dynamic valve control to switch between different pipeline configurations. The first and second vacuum switching valves can dynamically change the flow path, enabling maintenance operations on one intake pipeline section while maintaining negative pressure through the other section, thus adapting the system configuration based on operational needs.
2Ease of repair
If the intake pipeline is disassembled for cleaning and repair, then blockages can be removed, but the entire negative pressure path must be closed, complicating the maintenance process
Solution Approach 1:
The intake pipeline is segmented into independent maintainable sections with isolated valve control. The first intake pipeline section has its own vacuum switching valve, allowing it to be isolated and maintained independently from the second intake pipeline section, simplifying the maintenance process by eliminating the need to close the entire negative pressure path.
3Ease of operation
If a vacuum switching valve is used to break the vacuum airway for product removal, then product ejection is enabled, but fine debris and dust block the intake pipeline during operation
Solution Approach 1:
The system segments the vacuum pathway into multiple independent channels with separate valve control. This allows the intake pipelines to remain open and operational while product removal is achieved through controlled valve switching, preventing debris accumulation in the main intake path and maintaining its reliability.
Solution Approach 2:
The vacuum switching valves act as intermediary components that mediate between product removal requirements and intake pipeline reliability. By using the valves to control vacuum release and product ejection, the system prevents direct contamination of the intake pipeline with debris generated during product removal operations.

AI summary
A vacuum switching valve and a suction system having the same. The vacuum switching valve comprises: a valve body, comprising a first end and a second end, the second end being provided with an air inlet, an air outlet and a through hole; a valve element movably arranged in the valve body; a cylinder, the cylinder being connected to the first end and the valve element, the cylinder drives the valve element to move in the valve body, to close or open the air inlet; a stopper passing through the through hole, the stopper comprising a third end and a fourth end, the third end being connected to the valve element, the fourth end being located on the side of the through hole away from the valve element.
