[0002] Hollow fiber membrane is a self-supporting membrane with a fiber-like appearance, a hollow structure inside, and a surface covered with micropores. It is mainly used in food processing, water treatment, and biomedical fields. After production is completed, it is usually necessary to arrange the membrane fibers. This can ensure that the distribution of the membrane fibers in the membrane assembly is more uniform and can easily detect and eliminate defective membrane fibers that may occur during the production process, such as breakage, deformation, or contamination.

[0003] In the prior art, for example, Chinese patent CN214031867U discloses "a hollow fiber membrane wire arrangement device", which includes: a PLC, two winding wheels, a limiting system, a tension adjustment system, a guide wheel group and a terminal guide wheel. The PLC, the tension adjustment system, the limiting system, the guide wheel group and the terminal guide wheel are arranged in sequence; the PLC includes a telescopic rod fixedly connected to a screw motor, which is used to control the extension and retraction of the telescopic rod through the PLC.

[0004] At present, some hollow fiber membrane wire arrangement devices usually require a guide device for guidance when in use. Since the guide device operates independently, if the rotation speed of the winding wheel does not match the operating speed of the optical fiber guide device, the wire arrangement will still overlap, which requires manual correction, which is time-consuming and labor-intensive.

[0009] As a further preferred embodiment of the present technical solution, a sliding groove is provided at the top of the bottom plate, a support plate is slidably connected to the inside of the sliding groove, and the top of the support plate is in contact with the outer surface of the hollow fixed shaft.

[0010] As a further preferred embodiment of the present technical solution, positioning columns are fixedly connected to both side walls inside the guide frame, and outer surfaces of the positioning columns are slidably connected to the interior of the driven block.

[0011] As a further preferred embodiment of the present technical solution, a plurality of the shifting teeth are provided with limiting grooves, and the inner surfaces of the limiting grooves are in contact with the outer surface of the shifting wheel.

[0012] As a further preferred embodiment of the present technical solution, avoidance grooves are provided on the outer surface of the toggle wheel and located on both sides of the toggle rod, and the outer surfaces of the toggle teeth can move inside the avoidance grooves.

[0013] The utility model provides a hollow fiber membrane arranging device, which has the following beneficial effects:

[0014] (1) The utility model drives the driving wheel to rotate by driving the motor, and the driving wheel drives the driven wheel connected to the transmission belt to rotate.
