Adjustable Eccentric Vibrating Mill for Force Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibrating mills have a single oscillating effect that is inconvenient to adjust, requiring manual removal and adjustment of the vibrating motor to change the amplitude or exciting force, which is labor-intensive and inefficient.
Innovation Solution
An adjustment-facilitating vibrating mill design featuring an elastic mechanism with a grinding cylinder, a vibrating motor, and eccentric mechanisms, including adjustable eccentric blocks connected through a transmission mechanism and adjustment motor, allowing for precise adjustment of the exciting force without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of the vibrating motor is used to change amplitude or exciting force, then the adjusting function is achieved, but the operation convenience deteriorates and labor intensity increases
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated motor-driven system. The adjustment motor (62) connects to the eccentric block through a transmission mechanism (transmission rod 7 and transmission gear 8), automatically adjusting the exciting force without requiring manual removal and reassembly of the vibrating motor, thus resolving the contradiction between achieving adjustment function and maintaining operation convenience
Solution Approach 2:
The system enables self-adjustment through the adjustment motor that automatically modifies the eccentric block position based on control signals, eliminating the need for manual intervention. The adjustment mechanism serves itself by using motorized actuation rather than requiring operator disassembly and reassembly, improving both convenience and reducing labor intensity
2Adaptability or versatility
If manual removal and adjustment of the vibrating motor is used, then the exciting force can be changed, but the time consumption increases and productivity decreases
Solution Approach 1:
The patent replaces the time-consuming manual adjustment process with an automated motor-driven transmission system. The adjustment motor (62) drives the transmission rod (7) and transmission gear (8) to reposition the eccentric block quickly and precisely, eliminating the need for manual motor removal and reassembly, thus significantly reducing adjustment time and improving productivity
Solution Approach 2:
The adjustment mechanism allows for pre-positioning of the eccentric block at different angles to achieve desired exciting force levels. The system can be pre-configured with multiple adjustment positions, and the motor quickly transitions between these positions without requiring full manual disassembly, enabling faster adjustments and improving overall productivity

AI summary
An adjustment-facilitating vibrating mill includes a base, a grinding cylinder, and a vibrating motor. An elastic mechanism is arranged on the base. The grinding cylinder is fixedly connected to the elastic mechanism. The vibrating motor is arranged on the grinding cylinder. Two sides of the vibrating motor are provided with eccentric mechanisms; each eccentric mechanism includes a fixed eccentric block, an adjustment motor, and an adjustable eccentric block. The fixed eccentric block sleeves an output shaft of the vibrating motor. The adjustment motor is connected to the fixed eccentric block through a mounting seat. The adjustable eccentric block is connected to the adjustment motor through a transmission mechanism. According to the vibrating mill, an included angle between the adjustable eccentric block and the fixed eccentric block is adjusted using the adjustment motor and the transmission mechanism, so that an exciting force can be adjusted without removing the vibrating motor.
