Solution Overview
Problem
Existing grinding machines face issues with cleaning due to non-removable structures and high manufacturing costs and complexity with detachable designs, which lead to safety concerns and user dissatisfaction.
Innovation Solution
A grinding machine with an integrated double-disc structure and an assembling method that fixes the upper and lower grinding discs on a sealing base, using elastic sealing pieces for alignment and adjustment, allowing for easy disassembly, cleaning, and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the grinding structure is fixed non-removably at the bottom of the container, then the machine is easy to produce and process, but it is not easy to clean and food residues cannot be removed
Solution Approach 1:
The grinding structure is divided into an upper grinding disc and a lower grinding disc that can be separated from each other. The upper grinding disc is detachably connected to the container, while the lower grinding disc remains fixed. This segmentation allows the upper disc to be removed for cleaning, solving the cleaning difficulty while maintaining manufacturing simplicity.
2Ease of operation
If the upper grinding disc is fixed to the container by ultrasonic welding, then the grinding structure becomes detachable, but the disc may fall off during use due to thermal expansion differences
Solution Approach 1:
A sealing base is introduced as an intermediary component between the upper grinding disc and the container. The sealing base provides a stable mounting surface with a sealing cavity that accommodates the upper grinding disc, eliminating the direct ultrasonic welding connection and preventing disc detachment caused by thermal expansion differences.
3Ease of operation
If the blade and grinding structure are arranged detachably, then cleaning becomes easier, but assembly difficulty increases and manufacturing costs rise
Solution Approach 1:
The upper grinding disc and the sealing base are merged into an integrated assembly where the upper grinding disc is positioned within the sealing cavity of the sealing base. This merging simplifies the overall structure by reducing the number of separate components and assembly steps, thereby lowering manufacturing costs while maintaining detachability for cleaning.
4Productivity
If processing parameters of production equipment are adjusted for a certain type of detachable grinding machine, then that type can be produced, but other types cannot be produced, occupying equipment resources
Solution Approach 1:
The sealing base is designed with a universal sealing cavity structure that can accommodate different types of upper grinding discs. This universal design allows the same sealing base and production equipment to be used for manufacturing multiple types of grinding machines, improving equipment versatility and reducing resource occupation.

AI summary
The present disclosure relates to a grinding machine and an assembling method thereof. The grinding machine includes a container, a grinding assembly, and a sealing base. A bottom portion of the container defines a juice outlet. The sealing base seals the juice outlet. The sealing base is detachably connected with the container. The grinding assembly includes a cutting tool, an upper grinding disc, and a lower grinding disc arranged in sequence from top to bottom. A drive shaft is rotatably arranged on the sealing base. The cutting tool and the lower grinding disc are fixed on the drive shaft. The upper grinding disc is fixed on the sealing base. A first positioning step configured to position the upper grinding disc is formed on an inner wall of the juice outlet. A first elastic sealing piece is arranged between the upper grinding disc and the first positioning step.
