Patent ID: 11479436

Abstract:
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.
