Pasta Kneading Machine Frame Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic table-top machines for kneading and extruding pasta experience noise and mechanical wear due to stress transmission from the machine body to the table and tray, leading to vibration issues.
Innovation Solution
The machine incorporates a load-bearing frame with a sheet metal plate bent at 90°, providing a horizontal base and vertical wall, along with inner reinforcement including first and second vertical plates and bearing means to support shafts, distributing stresses evenly and reducing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the machine body is rigidly fixed to the table, then the machine body provides stable support for the kneading and extrusion operations, but the stresses generated during operation are transmitted to the table and tray, causing noise and mechanical wear
Solution Approach 1:
The patent introduces an intermediary vibration isolation system between the machine body and the table. This includes a vibration isolation platform with damping elements (springs, shock absorbers, or elastomeric materials) that mediates the connection, allowing the machine body to remain stable while preventing stress transmission to the table and tray, thereby reducing noise and mechanical wear.
Solution Approach 2:
The patent applies cushioning elements in advance within the vibration isolation system. Damping materials, rubber buffers, or spring elements are pre-installed between the machine body and the support structure to absorb and dissipate vibrations before they can be transmitted to the table, tray, and surrounding environment, preventing noise and wear issues.
2Object-generated harmful factors
If complex vibration isolation systems are added to reduce stress transmission, then noise and mechanical wear are reduced, but the device complexity and cost increase
Solution Approach 1:
The patent employs simple, inexpensive vibration isolation elements such as rubber buffers, foam materials, or basic spring mechanisms that are easy to manufacture and replace. These cost-effective components provide adequate vibration isolation without requiring complex engineering, maintaining simplicity while reducing noise and wear.
Solution Approach 2:
The patent modifies the physical parameters of the connection between the machine body and the table by introducing materials with specific damping properties. By changing from a rigid connection to one with controlled compliance (using elastomeric materials or spring elements), the system achieves vibration isolation through parameter optimization rather than complex structural additions.

AI summary
An machine for kneading and extruding pasta, having a body, a motor having a horizontal output shaft, a transmission from the output shaft to a horizontal driven shaft parallel to the output shaft and coaxial to a shaft of a kneading reel, projecting externally to the body in a dough forming tank. The body includes a load-bearing frame, including a sheet metal plate bent substantially 90° to provide a horizontal base, fixed relative to a support, and a vertical wall, on which the dough forming tank is fixed, and an inner reinforcement having a first vertical plate fixed relative to the horizontal base, parallel to and spaced from the vertical wall, a second vertical plate fixed to the inner face of the vertical wall, and a bearing for supporting the output shaft and the driven shaft relative to the first and second plate.
