The single component double twisted polyester fiber production apparatus according to claim 1, characterized in that: The left side of the top plate (3) is fixedly connected with an electric sliding rail (33) through a connecting plate, and the electric sliding rail (33) is located below the winding cylinder (7), one side of the electric sliding rail (33) is provided with a sliding seat (34), and the side, away from the electric sliding rail (33), of the sliding seat (34) is fixedly connected with a third guide ring (35) matched with the polyester fiber body (17).

4. The single component double twisted polyester fiber production apparatus according to claim 2, characterized in that: The main pipe (21) is provided with an air pressure gauge (30) matched with the air pump (31), and the mutually distant ends of the extension seats (27) are in arc structures.

5. The single component double twisted polyester fiber production apparatus according to claim 3, characterized in that: The left side of the top of the inner cavity of the auxiliary frame (18) is rotatably provided with a first guide wheel (19) matched with the polyester fiber body (17), the right side of the inner cavity of the auxiliary frame (18) is sequentially rotatably provided with two groups of second guide wheels (20) matched with the polyester fiber body (17) along the left-right direction, and the first guide wheel (19) is located above the second guide wheels (20), and the auxiliary guide wheels (367) are located on the sides close to each other of the second guide wheels (20).

6. The production method of a single-component double-twisted polyester fiber production apparatus according to any one of claims 1 to 5, characterized in that: The method comprises the following steps: S1, the user starts the air pump (31), the air pump (31) transmits the gas into the main pipe (21) through the butt bend (32), and transmits the gas into the cavity (25) through the air pipe (22), and finally sprays out through two groups of air injection holes (24) to the polyester fiber body (17), the positioning block (23), the limiting seat (26), the air pipe (22), the air injection hole (24) and the cavity (25) can constitute a pre-networker, and two groups of air injection holes (24) are symmetrically distributed at an angle of 45 degrees with the horizontal and vertical plane, when two air flows are opposite to each other, the polyester fiber body (17) is interlaced, the polyester fiber body (17) can be prevented from rotating to produce torque, and the production stability of post-processing is improved; S2, then the user monitors the air pressure in the main pipe (21) through the air pressure gauge (30) until the air pressure reaches the preset value, at this time the user starts two groups of first motors (12) and electric sliding rails (33) through the controller, at this time two groups of first motors (12) can drive the fixed cylinder (5) and the winding cylinder (7) to rotate, one side releases the polyester fiber body (17), and the other side winds the polyester fiber body (17) after processing, at the same time the electric sliding rail (33) can drive the sliding seat (34) and the third guide ring (35) to move back and forth, so as to drive the polyester fiber body (17) to move back and forth, so that the polyester fiber body (17) is wound more evenly on the winding cylinder (7); S3, in order to ensure the stability of the tension, the tension of the polyester fiber body (17) needs to be adjusted according to the on-site situation, at this time the user starts the second motor (361) through the controller, and presets the rotation amplitude of the second motor (361), the second motor (361) can drive the driving frame (362) to rotate, so as to drive the driving plate (363) to swing, and then under the assistance of the fixed square column (368), the U-shaped frame (366) and the auxiliary guide wheel (367) can be pulled to move, so as to adjust the tightness of the polyester fiber body (17) according to the need, and improve the production stability.
