Automatic grinder and grinding method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinders lack the ability to prevent contamination of materials when grinding multiple substances due to the reuse of the same grinding sleeves and heads, leading to compromised quality and taste of subsequent powders.
Innovation Solution
An automatic grinder design featuring interchangeable grinding sleeves and heads, with an adjustable gap mechanism and a sealed compartment to prevent the introduction of impurities, ensuring the quality and taste of each material is maintained by using different components for each grinding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same grinding head and grinding sleeve are used for multiple materials, then device complexity is reduced, but material quality deteriorates due to contamination
Solution Approach 1:
The grinding system is segmented into detachable components: the grinding head can be separated from the grinding sleeve. This allows different grinding heads to be used for different materials while keeping the grinding sleeve stationary, preventing cross-contamination between materials while maintaining relatively simple device structure
Solution Approach 2:
The grinding head is extracted as a separate, replaceable component from the grinding sleeve. By taking out the grinding head, the system enables different grinding heads to be used for different materials without affecting the grinding sleeve, thus preventing material contamination while keeping the overall device complexity low
2Ease of operation
If the grinding head is fixed to the material container body, then ease of operation is improved, but adaptability decreases when grinding different materials
Solution Approach 1:
The grinding head connection is made dynamic rather than fixed. The grinding head can be rotated relative to the material container body and locked at different angles, allowing the system to adapt to different grinding requirements for various materials while maintaining ease of operation through simple rotational adjustment
3Productivity
If materials are fed through the same grinding sleeve for multiple materials, then productivity is improved, but material quality deteriorates due to particle introduction
Solution Approach 1:
A sealing structure acts as an intermediary between the grinding head and grinding sleeve interface. This sealing intermediary prevents particles and air from entering the grinding zone during material feeding, maintaining material quality while allowing continuous high-productivity grinding operations
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 automatic grinder effectively prevents contamination by allowing separate grinding sleeves and heads for each material, ensuring the quality and taste are preserved, and the adjustable gap mechanism allows for precise control over particle size.

AI summary
An automatic grinder and a grinding method thereof. The grinder includes a control structure and at least one material container assembly. The control structure includes a driving assembly and a connecting structure connected to the driving assembly. The material container assembly includes a material container body (20), a grinding head (22) fixedly connected to the material container body (20), and a grinding sleeve (25) rotatably connected to the grinding head (22). A recess (201) is provided on the material container body (20), and the connecting structure is engaged with the recess (201). The grinding head (22) is fitted into the grinding sleeve (25), and the grinding head (22) and the grinding sleeve (25) define therebetween a material compartment (40) for accommodating a material. The driving assembly drives, via the connecting structure, the material container body (20) to rotate. The material container body (20) drives the grinding head (22) to rotate. The grinding head (22) moves relative to the grinding sleeve (25), such that the material between the grinding head (22) and the grinding sleeve (25) is ground into powder. The automated grinder is provided with different grinding sleeves and grinding heads for grinding a variety of materials, and prevents the introduction of impurities during feeding, thereby preserving the original flavor of the material.
