Artificial lung membrane fiber weaving equipment includes key mechanisms such as membrane curtain weaving and edge cutting, and needs to adapt to the processing requirements of membrane curtains of different widths. In the membrane curtain cutting stage, traditional processes generally use ultrasonic cutting technology, but this method has the following significant shortcomings: 1. There are strict requirements for the composition of membrane fiber materials. Membrane fibers with a high polymer content will carbonize during the cutting process, affecting the pass rate of the membrane curtain.
[0003] 2. Ultrasonic devices occupy a large space, and the design for amplitude adjustment makes it difficult to coordinate the cutter wheel with the mold for adjustment; 3. Ultrasonic devices are expensive, and the cutting wheel, mold, and vibrator are all vulnerable parts, resulting in high operating costs in the later stages. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable roller cutting mechanism. This mechanism mainly solves the problems of difficulty in adjusting the cutting width of the membrane curtain, strict requirements on the composition of the membrane fibers in the traditional ultrasonic cutting method, and high maintenance costs in the later stage.
[0005] The objective of this utility model is achieved through the following technical solution: An adjustable roller cutting mechanism comprises three parts: a width adjustment device, a roller device, and an auxiliary wheel device.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are: This invention effectively solves the pain points of traditional ultrasonic cutting technology. Traditional technology has strict requirements on the composition of membrane fiber materials.

Through targeted design, this invention not only significantly reduces the impact of membrane fiber material composition on the cutting effect and greatly improves the yield of the membrane curtain, but also has the advantages of small footprint, convenient adjustment, and low maintenance cost.
