Solution Overview
Problem
Conventional grinding machines face issues with dust accumulation on the grinding disc and transmission members, leading to friction and temperature rise, and moisture ingress during wet grinding, which requires frequent disassembly and maintenance, increasing costs and reducing robot working hours.
Innovation Solution
A grinding machine design featuring a pressure cavity with a gas intake pipe creating a positive-pressure environment, preventing dust and moisture entry by continuously releasing high-pressure gas through a pressure release gap, enhancing heat dissipation and maintaining a dry environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a dust sucking structure is used to remove dust during grinding, then dust can be extracted from the grinding area, but dust accumulates on the grinding disc and transmission member causing friction and temperature rise
Solution Approach 1:
Instead of using suction to remove dust (negative pressure), the invention uses high-pressure gas to blow dust away (positive pressure). The gas blowing structure reverses the conventional approach by pressurizing gas through a gas source to create positive pressure in the cavity, which actively pushes dust and moisture away from critical components rather than attempting to suck them away.
Solution Approach 2:
The invention employs pneumatic principles by introducing a gas source that generates high-pressure gas. This gas is directed into the cavity through a gas blowing structure, creating a positive pressure environment that prevents dust and moisture accumulation. The pneumatic system replaces the mechanical dust sucking approach with a more effective gas-based cleaning mechanism.
2Adaptability or versatility
If wet grinding is performed, then grinding can proceed in a wet environment, but moisture enters the grinding machine requiring disassembly for evaporation
Solution Approach 1:
The invention performs preliminary action by creating a positive pressure environment before moisture can cause problems. The high-pressure gas is continuously supplied to the cavity, forming a protective barrier that prevents moisture from entering critical internal components in the first place, eliminating the need for subsequent disassembly and evaporation steps.
Solution Approach 2:
The high-pressure gas acts as an intermediary substance between the wet grinding environment and the internal machine components. It creates a protective atmosphere in the cavity that allows wet grinding to proceed while preventing moisture from reaching sensitive parts, thus enabling adaptability without the time loss of disassembly.
3Reliability
If the grinding machine is disassembled for moisture evaporation after each use, then moisture can be removed, but working hours are reduced and costs increase
Solution Approach 1:
The high-pressure gas protection operates continuously during the grinding process, maintaining constant positive pressure in the cavity. This continuous protective action prevents moisture accumulation throughout operation, eliminating the need for intermittent disassembly and evaporation cycles, thereby maintaining both reliability and productivity.
Solution Approach 2:
The system provides self-service protection by automatically maintaining a positive pressure environment that continuously prevents moisture ingress. The gas source and blowing structure work autonomously to protect the internal components, eliminating the need for external intervention through disassembly and manual drying procedures.
4Object-generated harmful factors
If dust accumulates on transmission members, then friction increases, but conventional dust sucking fails to prevent this accumulation
Solution Approach 1:
The invention inverts the dust removal approach by using positive pressure gas blowing instead of negative pressure suction. The high-pressure gas directly targets the transmission members and grinding disc, actively blowing dust away from these surfaces rather than attempting to suck it away, thereby preventing friction and temperature rise more effectively.
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
The positive-pressure environment effectively prevents dust and moisture ingress, reduces maintenance needs, and improves heat dissipation, making the grinding machine suitable for both dry and wet grinding applications while minimizing downtime and extending robot operation.
Implementation Method 1
The gas intake pipe induces a high-pressure gas into the pressure cavity. The pressure cavity receives an effect of the high-pressure gas to cause its internal pressure to be greater than the pressure outside the grinding machine body
Implementation Method 2
The pressure cavity is in communication with the pressure release gap to allow the high-pressure gas to be continually released via the pressure release gap, so as to prohibit external dust from entering the pressure cavity

AI summary
A grinding machine includes a grinding machine body and a grinding disc connected to the grinding machine body. The grinding machine body is provided with a pressure cavity at a position facing the grinding disc and a gas intake pipe corresponding to the pressure cavity. A pressure release gap in communication with the pressure cavity is formed between the grinding machine body and the grinding disc. The gas intake pipe induces a high-pressure gas into the pressure cavity, which receives an effect of the high-pressure gas to become a positive-pressure environment. The high-pressure gas is continually released via the pressure release gap to prohibit external dust from entering the pressure cavity. Thus, the grinding machine is capable of preventing dust from accumulating in the pressure cavity as well as effectively preventing moisture from entering the pressure cavity when the grinding machine is applied for wet grinding.
