[0002] Flat membrane is a new type of high-efficiency sewage treatment and reuse process that combines membrane high-efficiency separation technology with biodegradation to replace the secondary sedimentation tank. All suspended matter and colloids are separated and retained by the membrane. The membrane separation increases the concentration of activated sludge in the aeration tank, increases the rate of biodegradation, and reduces the discharge of residual sludge. When preparing the flat membrane, in order to facilitate the subsequent transportation and processing of the flat membrane, the flat membrane needs to be rolled up.

[0003] In the prior art, due to the different widths of flat membranes, it is necessary to adjust the width between the shaft and the equipment to achieve the purpose of winding. However, the shaft and the paper tube need to be fixed in position in turn during repeated adjustments, which reduces production efficiency. At the same time, when the pressure of the flat membrane is too small during winding or there is a large difference in pressure on the membrane surface, it is easy to cause uneven end surfaces after winding. Therefore, we propose a winding device for processing hollow fiber flat membranes to solve the above problems. Utility Model Content
