Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-unit die cutting & hot stamping machines suffer from deformation of the chain, leading to printing accuracy issues due to tension changes, which existing positioning devices cannot effectively fine-tune in real-time, resulting in reduced efficiency and increased labor costs.
Innovation Solution
A precision positioning device with positioning blocks on a rotating rod matching reference surfaces on a gripper, allowing for consistent positioning and adjustment to compensate for chain deformation by adjusting the distance between the blocks and matching surfaces, ensuring accurate and efficient die cutting & hot stamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-unit die pressing element and aluminum foil control element are employed to accomplish multiple hot stamping and die cutting, then production efficiency is improved and production cycle is shortened, but the chain undergoes frequent tension changes causing deformation and reducing printing accuracy
Solution Approach 1:
The patent employs adjustable positioning elements that can be fine-tuned to compensate for chain deformation. The positioning elements include adjustable positioning blocks that can be moved along the chain to maintain accurate registration despite tension changes and chain stretching over time, thus preserving printing accuracy while maintaining high productivity
Solution Approach 2:
The patent incorporates a positioning reference system that provides feedback on the actual position of the chain relative to the workpiece. This allows for real-time detection and compensation of chain deformation through adjustable positioning elements, ensuring that printing accuracy is maintained even as the chain undergoes tension changes during operation
2Duration of action of stationary object
If existing positioning devices are used, then the apparatus can operate continuously, but positioning deviation cannot be fine-tuned in time and processing accuracy deteriorates
Solution Approach 1:
The patent replaces fixed positioning devices with dynamic, adjustable positioning elements that can be fine-tuned during operation. The positioning blocks can be adjusted along the chain to compensate for deformation, allowing the system to maintain both continuous operation and high processing accuracy through real-time adaptability
3Manufacturing precision
If the printing apparatus is turned off for constant adjustment to guarantee processing accuracy, then positioning accuracy is maintained, but working efficiency is reduced and labor cost increases
Solution Approach 1:
The patent implements a self-adjusting positioning system where the adjustable positioning elements can be fine-tuned to compensate for chain deformation without requiring complete shutdown of the apparatus. This reduces downtime and labor costs while maintaining positioning accuracy, as the system can be adjusted during operation rather than requiring frequent interruptions

AI summary
A precision positioning device of a unit-type die cutting & hot stamping machine includes a positioning element on an input end of a first imprinting element and a positioning element on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. Each positioning element is constituted by a positioning assembly installed symmetrically on each end of the imprinting element. The positioning assembly includes a positioning rod which can rotate against an installation shaft. Each positioning rod includes a positioning block which is provided with a reference surface. A rear side of the gripper is provided with a reference matching surface. By the positioning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure.
