Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fully automatic gravure plate-making systems experience low contact tightness of chuck cones with the unprocessed plate-making roll, leading to plating defects.
Innovation Solution
A single-motor-driven gravure cylinder chuck mechanism with a pair of opposed chuck cones and a servo motor for synchronized contact and separation, utilizing ball screws and motor control for precise positional and torque control, enhancing contact tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motors are provided to respective chuck cones for individual chucking, then the chuck cones can independently adjust, but the contact tightness with the unprocessed plate-making roll becomes low
Solution Approach 1:
The patent combines two independent motor-driven chuck cone systems into a single motor-driven synchronized chucking system. The single motor drives both chuck cones simultaneously through a common transmission mechanism, ensuring they move together and apply uniform pressure on the unprocessed plate-making roll, thereby improving contact tightness while maintaining operational capability
2Reliability
If a single motor is used to drive both chuck cones, then contact tightness is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a synchronous belt or gear mechanism as an intermediary transmission component that couples the single motor to both chuck cones. This intermediary mechanism ensures synchronized movement of both chuck cones while keeping the overall structure relatively simple and maintainable, balancing the trade-off between improved contact tightness and device complexity

AI summary
Provided is a single-motor-driven gravure cylinder chuck mechanism that is enhanced in contact tightness of chuck cones with respect to an unprocessed plate-making roll in each processing unit of a fully automatic plate-making system. The gravure cylinder chuck mechanism is to be used for a processing unit of the fully automatic gravure plate-making processing system for manufacturing a plate-making roll by performing a series of processes on an unprocessed plate-making roll. The gravure cylinder chuck mechanism includes: a pair of chuck cones provided to be opposed to each other, for chucking both end surfaces of the unprocessed plate-making roll; chuck cone moving means for allowing the pair of chuck cones to be freely brought into contact with and separated away from both the end surfaces of the unprocessed plate-making roll; and a single motor for driving the chuck cone moving means. The single motor allows the pair of chuck cones to be freely brought into contact with and separated away from both the end surfaces of the unprocessed plate-making roll so that the pair of chuck cones chuck the unprocessed plate-making roll.
