[0025] When producing polyester monofilaments, firstly, the polyester monofilament raw material is introduced into the stirring barrel 3 along the feed port 6, and then the stirring assembly and the heating ring 4 are used to heat and stir the polyester monofilament raw material entering the stirring barrel 3 to increase the activity of the raw material. After the stirring is completed, the raw material after stirring is passed through the electromagnetic valve 18 along the connecting pipe 21 into the extrusion barrel 2, and then the displacement assembly is used to drive the piston block 7 to move inside the extrusion barrel 2, so that the piston block 7 extrude the polyester monofilament raw material from the discharge port 5 with the assistance of the rubber ring 20, thereby completing the production of the polyester monofilament. In this way, the displacement assembly is used to replace the previous screw rod conveying method for extrusion, which improves the production efficiency of the polyester monofilament, and can effectively avoid the residual raw materials, thereby improving the use efficiency of the extrusion molding machine.

[0026] like Figure 1-Figure 5 As shown, the displacement assembly includes a mounting plate 11, which is fixedly connected to one side of the extrusion barrel 2, a worm 14 is rotatably connected to the bottom of the mounting plate 11, a worm wheel 13 is rotatably connected to one side of the extrusion barrel 2, a threaded rod 8 is connected to the internal thread of the worm wheel 13, one end of the threaded rod 8 is fixedly connected to the piston block 7, the outer side of the worm 14 is meshed with the tooth edge of the worm wheel 13, a guide rod 9 is fixedly connected to one side of the piston block 7, one end of the guide rod 9 extends to the outside of the extrusion barrel 2 and is fixedly connected to the limiting plate 10, a servo motor 12 is fixedly installed on the top of the mounting plate 11, and the output end of the servo motor 12 passes through the mounting plate 11 and is fixedly connected to the worm 14.

After the stirring is completed, the raw material after stirring is introduced into the extrusion barrel 2 along the connecting pipe 21 through the electromagnetic valve 18, and then the servo motor 12 is used to drive the worm 14 to rotate at the bottom of the mounting plate 11, so that the worm wheel 13 meshingly connected therewith rotates on one side of the extrusion barrel 2, so that the threaded rod 8 connected to the internal thread of the worm wheel 13 pushes the piston block 7 to move between the inner walls of the extrusion barrel 2 under the action of the guide rod 9, so that the piston block 7 extrude the polyester monofilament raw material from the discharge port 5 under the auxiliary action of the rubber ring 20, thereby completing the production of the polyester monofilament.
