Adjustable Press Roller Registration for Plastic Flooring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional equipment for manufacturing plastic flooring struggles to accurately align the pattern area of the printing layer with the pressing pattern section of the third press roller, especially when the printing layer offsets at an angle, leading to registration errors.
Innovation Solution
A device with a rolling unit and an adjusting unit, where the rolling unit includes a press roller set with a third and fourth press roller, and the adjusting unit features a movable segment driven by a power source to correct misalignment by moving the pattern area to align with the pressing pattern section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional registration system with sensors and encoders is used, then speed information and color code detection are achieved, but accurate alignment of pattern area with pressing pattern section cannot be achieved when printing layer offsets at an angle
Solution Approach 1:
The patent makes the press roller set dynamically adjustable by introducing a movable segment that can shift position along the printing layer's width direction. The press roller set includes fixed and movable segments that can be adjusted relative to each other, allowing the system to dynamically correct angular offsets between the printing layer pattern area and the pressing pattern section, transforming a static registration system into a dynamic one capable of real-time correction.
Solution Approach 2:
The press roller set is divided into fixed and movable segments. The movable segment can be independently adjusted along the width direction of the printing layer, allowing selective correction of pattern misalignment. This segmentation enables the system to address angular offsets by moving only the necessary portion of the press roller set without affecting the entire system.
2Adaptability or versatility
If fixed press roller configuration is used, then device structure is simple, but cannot correct angular offset between printing layer pattern and pressing pattern section
Solution Approach 1:
The press roller set is designed with both fixed and movable segments, where the movable segment can be adjusted along the width direction of the printing layer. This dynamic configuration allows the system to adapt to angular offsets between the printing layer pattern area and the pressing pattern section while maintaining a relatively simple overall structure.
Solution Approach 2:
The press roller set is segmented into fixed and movable portions. The movable segment can be independently positioned to correct angular misalignment, providing adaptability without requiring complete reconfiguration of the entire press roller system, thus balancing versatility with structural simplicity.
3Manufacturing precision
If conventional registration system is used, then basic pressing function is achieved, but pattern area cannot be accurately aligned with pressing pattern section under offset conditions
Solution Approach 1:
The system incorporates a movable segment in the press roller set that can be adjusted along the width direction of the printing layer. This dynamic adjustment capability enables accurate alignment of the pattern area with the pressing pattern section even when angular offsets occur, significantly improving manufacturing precision while maintaining ease of operation through automated or semi-automated adjustment mechanisms.
Solution Approach 2:
By dividing the press roller set into fixed and movable segments, the system enables precise local adjustment of the pressing position. The movable segment can be independently positioned to correct pattern misalignment, achieving high manufacturing precision without requiring complex overall system reconfiguration.
