Waste gas suction device for spinning production

The utility model relates to the technical field of spinning, in particular to a waste gas suction device for spinning production. Comprising a shell, a waste extraction ring, a distribution plate, an air pressure adjusting structure and a buffering structure, a suction pump is started to extract air, the air pressure adjusting structure is used for adjusting the air suction pressure of exhaust gas to the proper pressure intensity, air in a harness cord hole is absorbed into a waste extraction cavity after passing through a distribution hole, and due to the radial arrangement of the distribution hole, airflow in the radial direction of the harness cord hole is formed in the harness cord hole; when polyester staple fiber spinning with higher temperature falls from the spinning assembly and passes through the harness cord hole, the generated waste gas is sucked into the waste extraction cavity along the radial airflow of the harness cord hole, so that the waste gas generated by the polyester staple fiber spinni
