Technical Field
[0001] The utility model relates to the technical field of spinning and stretching, in particular to a stretching and winding device for polyester monofilament. Background Art
[0002] Spinning and stretching is one of the important processes in the production of synthetic fibers. The primary fiber filaments are continuously stretched through a pre-stretching machine to rearrange the molecular structure of the fiber and improve the tensile strength and other mechanical properties of the fiber. At the same time, stretching will make the fiber thinner and longer, and improve the uniformity and glossiness of the fiber.
[0003] During the stretching process, the spinning needs to be softened and then stretched by pulling the ends. During this process, after stretching to the specified position, the stretching part needs to be reset before the next stage of stretching can be carried out. At this time, continuous stretching cannot be carried out during the time required for reset, which will lead to reduced stretching efficiency and difficulty in ensuring the continuity of stretching.

DETAILED DESCRIPTION
[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

A mounting frame 11 is provided, on which a winding disk 3 and a raw material disk 2 are rotatably connected, a winding motor 31 is fixed on the mounting frame 11 at a position corresponding to the winding disk 3, a wire inlet hole 12 and a wire outlet hole 13 are respectively provided on both sides of the stretching box 1, the position of the wire inlet hole 12 is aligned with the position of the raw material disk 2, and the position of the wire outlet hole 13 is aligned with the position of the winding disk 3, an outer bracket 4 is fixed on both sides of the stretching box 1 and at a position corresponding to the wire inlet hole 12 and the heat dissipation hole 15, a wire wheel 41 is rotatably connected inside the outer bracket 4, and a controller 14 is fixed on the front side of the stretching box 1, which controls and is electrically connected to the winding motor 31 and the driving motor 63.
[0019] A heat insulation board 16 is fixed at the center position in the stretching box 1, and a threading hole 17 is opened on the heat insulation board 16. A heat dissipation hole 15 is opened at the upper end of the stretching box 1 and at a position corresponding to the stretching roller 8. A heat dissipation fan 5 is installed in the heat dissipation hole 15. A dustproof net 51 is fixed at the upper end of the stretching box 1 and at a position corresponding to the heat dissipation hole 15.
[0020] In this embodiment, the entire device is first connected to an external power supply, and then the yarn is passed through the stretching box 1 and wound in the winding disk 3.
