[0002] Spinning nylon is prone to monomer in production process due to the characteristics of nylon 6, and monomer suction system is the most widely used system in spinning nylon, which is arranged in production spinning position (8 or 10 spinning positions arranged in a row). The monomer suction system can quickly remove the monomer generated after the nylon 6 melt leaves the spinneret, and will not affect the state of the monofilament.

[0003] As shown in Figure 1 The existing monomer suction system includes a suction hood 20, a monomer water inlet pipe 21, a first pipeline 22 and a second pipeline 23 connected between the suction hood 20 and the first pipeline 22. The number of suction hood 20, monomer water inlet pipe 21, first pipeline 22 and second pipeline 23 is adapted to the spinning position. The upper end of the first pipeline 22 is closed, and the upper end of the monomer water inlet pipe 21 extends into the first pipeline 22. The spinning monomer circulating water is transported to the first pipeline 22 through the monomer water inlet pipe 21 by the water pump, and water is sprayed into the first pipeline 22 through the nozzle 24. The water flow generates negative pressure in the suction hood 20 and the second pipeline 23 during the flow process, and the monomer is sucked into the monomer suction system after passing through the suction hood 20. The monomer will adhere to the suction hood 20 due to the sudden drop in temperature after being sucked into the suction hood 20, which will clog the suction pipe and reduce the suction force at the end of the suction pipe; the existing technology for cleaning the suction hood is manual operation, which is low in efficiency and even easy to damage the suction hood during disassembly.
