Rotatable Trimmer Spindle Mounts for Multi-Diameter Container Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container trimming machines require extensive adjustments and changes in components, including gears and blades, to accommodate different container diameters, leading to increased time, cost, and complexity in the change-over process.
Innovation Solution
A trimmer device with a circular inner and outer mounting block system, where the inner and outer spindles are positioned through respective bores, allowing for rotational adjustment relative to the turret shaft to accommodate varying container diameters without changing gears, and utilizing a cartridge assembly for easy setup and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing trimming machines use fixed mounting blocks with precise blade adjustments, then trimming precision is maintained, but the change-over process becomes complex and time-consuming when accommodating different container diameters
Solution Approach 1:
The mounting blocks are made rotatable about the turret shaft, allowing dynamic adjustment of the distance between inner and outer spindles. This rotational capability enables the same mounting blocks to accommodate multiple container diameters without complex reconfiguration, resolving the contradiction between maintaining precision and reducing change-over complexity
Solution Approach 2:
The mounting blocks serve multiple functions: they provide precise blade positioning, enable diameter adjustment through rotation, and allow the same components to be used across different container sizes. This multi-functionality eliminates the need for separate mounting blocks for each diameter, reducing device complexity while maintaining precision
2Adaptability or versatility
If multiple sets of gears are used to accommodate different container diameters, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
A single set of gears is designed to work with all container diameters by combining the gears with rotatable mounting blocks. The gears provide rotational motion while the mounting blocks provide diameter adjustment through their own rotation, creating a universal system that eliminates the need for multiple gear sets
Solution Approach 2:
The diameter adjustment function is separated from the gear system by making the mounting blocks independently rotatable. This segmentation allows the gear system to remain simple and universal while the mounting blocks handle the adaptability to different diameters, reducing overall device complexity
3Manufacturing precision
If precise blade adjustments are made for each container diameter, then trimming quality is maintained, but setup time increases
Solution Approach 1:
The rotatable mounting blocks enable rapid adjustment of spindle distances by simply rotating the blocks to different angular positions, rather than making precise mechanical adjustments to blade positions. This dynamic adjustment mechanism maintains trimming quality while significantly reducing setup time
Solution Approach 2:
The mounting blocks can be pre-positioned at specific rotational angles corresponding to different container diameters. This preliminary positioning allows for quick changeovers by simply rotating to the pre-determined angle, eliminating the need for time-consuming precise adjustments during each change-over
