Solution Overview
Problem
Existing fiber product suction systems face issues with uneven and insufficient negative pressure on longer folding wheels or at higher rotation speeds, leading to paper falling and poor quality folding.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the passage length or folding wheel length is increased, then the folding wheel can handle longer paper products, but the negative pressure becomes insufficient or uneven in the middle section
Solution Approach 1:
The passage is divided into multiple segments with individual valves at different positions along the folding wheel. Each valve independently controls the suction channels in its region, allowing localized adjustment of negative pressure. This segmentation enables even distribution of negative pressure across the entire length of the folding wheel, solving the problem of insufficient or uneven pressure in the middle section of long folding wheels.
2Productivity
If the rotation speed of the folding wheel is increased, then the productivity improves, but the negative pressure becomes insufficient and paper may fall from the folding wheel
Solution Approach 1:
The multiple valves are positioned to create negative pressure in advance across different sections of the folding wheel. By having valves distributed along the passage, the system preliminarily establishes sufficient negative pressure throughout the folding wheel before the paper reaches each section, ensuring paper remains firmly attached even at high rotation speeds.
3Device complexity
If two connecting pipes are used to connect the air extractor to both ends of the passage, then the system structure is simple, but the negative pressure generation speed is slow and insufficient in the middle section
Solution Approach 1:
Instead of using only two connecting pipes at the ends, the system segments the passage and places multiple valves at different positions. This segmentation allows the air extractor to simultaneously create negative pressure at multiple locations along the passage, significantly reducing the time required for negative pressure formation and ensuring adequate pressure in the middle section without requiring excessive piping complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system generates even negative pressure across the folding wheel, preventing paper from falling and improving the quality of folded products even at high speeds and longer lengths.
Implementation Method 1
the air extractor can extract the gas in the suction channels through the plurality of valves and the connecting channels, so that the suction channels at the top surface of the protruding wheel will generate an even negative pressure, and the paper will be quickly sucked on the folding wheel
Implementation Method 2
the suction channels at the top surface of the protruding wheel will generate an even negative pressure, and the paper will be quickly sucked on the folding wheel

AI summary
The invention provides a fiber product suction system, comprising a folding wheel and a plurality of valves. The folding wheel comprises a plurality of protruding wheels and a plurality of recessing wheels adjacent each other. A plurality of suction channels and at least one connecting channel are disposed within the protruding wheel, wherein the connecting channel is fluidly connected to the suction channel. The valve is disposed on the recessing wheel of the folding wheel, and includes a connecting opening, a valve channel and a plurality of valve openings, wherein the valve openings are disposed on two sides of the valve, and are fluidly connected to the connecting opening via the valve channel. An air extractor can extract the gas in each suction channel through the valve, and generate a negative pressure on part of suction channels of the protruding wheel, so that the fiber product suction system can be used to suck and fold paper.
