Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the utility model, the heat exchanger for heat recovery of textile equipment includes a drying box 1, a winding roller 2 for winding the yarn is provided on one side of the drying box 1, a circulation pipe 3 for circulating heat is provided on the outer wall of the drying box 1, and a circulation mechanism 4 is provided on the drying box 1 and the circulation pipe 3; the circulation mechanism 4 includes a transmission unit and a circulation unit; the transmission unit is used to provide power for the operation of the circulation unit; the circulation unit is used to recycle the hot air rising to the top.

[0019] The transmission unit includes a first transmission rod 401, a rotating rod 402, a second transmission rod 403, a turntable 404, a first gear 405, and a second gear 406. The first transmission rod 401 is eccentrically rotatably connected to the outer wall of the end of the circulation pipe 3, and is used to transmit power to the rotation of the rotating rod 402. The rotating rod 402 is rotatably mounted on the inner wall of the drying chamber 1, and is used to provide power to the rotation of the second transmission rod 403. The second transmission rod 403 is eccentrically rotatably connected to the outer wall of the end of the rotating rod 402, and is used to drive the turntable 404 to rotate synchronously. The turntable 404 is rotatably connected to a support on the drying chamber 1, and is used to drive the first gear 405 to rotate synchronously. The first gear 405 is fixed to one end of the shaft of the turntable 404, and is used to drive the second gear 406 to rotate. The second gear 406 is fixed to the outer wall of the connecting rod 407, and is used to drive the connecting rod 407 to rotate synchronously.

[0020] The circulation unit includes a connecting rod 407, a fan blade 408, and a third transmission rod 409. The connecting rod 407 passes through the second gear 406 and is rotatably connected to the inner wall of the drying chamber 1. The connecting rod 407 is used to synchronously drive the fan blade 408 to rotate. The fan blade 408 is fixed to the end of the connecting rod 407 and is used to draw hot air through the circulation pipe 3. The third transmission rod 409 is eccentrically rotatably connected to the outer wall of one side of the first gear 405. The third transmission rod 409 is used to synchronously drive the other first gears 405 to rotate. There are multiple circulation pipes 3, which are symmetrically and evenly distributed on both sides of the drying chamber 1.

[0021] In this embodiment: In the prior art, when drying the yarn, the yarn is wound around the take-up roller 2 through the drying chamber 1, and the take-up roller 2 winds up the yarn. The yarn is then dried in the drying chamber 1. During the winding process, the rotation of the take-up roller 2 synchronously drives one end of the first transmission rod 401, which is eccentrically connected to the outer wall, to rotate circumferentially. This drives the other end of the first transmission rod 401, which is eccentrically connected to the rotating rod 402, to rotate. The rotating rod 402 synchronously drives one end of the second transmission rod 403 to rotate circumferentially about the axis of the rotating rod 402, thereby driving the other end of the second transmission rod 403 to rotate. A turntable 404, eccentrically connected at one end, rotates. The rotating turntable 404 synchronously drives the first gear 405 to rotate, causing the second gear 406 meshing above the first gear 405 to rotate. The rotating second gear 406 synchronously drives the connecting rod 407 and the fan blade 408 to rotate. The rotating fan blade 408 absorbs the hot air rising after drying the yarn, allowing the hot air to enter the circulation pipe 3 and be discharged through the rotation of the fan blade 408. The hot air then acts on the yarn again from the lower inner side of the drying chamber 1 to dry the yarn, increasing the heat of the drying tank inside the drying chamber 1 and improving the utilization rate of heat energy.

[0022] Please refer to this carefully. Figures 1-3 There are multiple first gears 405 and second gears 406, which are evenly distributed on the inner wall of the drying box 1. The inner wall of the circulation pipe 3 is formed with space for the fan blades 408 to rotate. The two ends of the first transmission rod 401 are equidistant from the axis of the rotating rod 402 and the winding roller 2. Two symmetrically arranged fan blades 408 are fixed to the outer wall of the connecting rod 407.

[0023] In this embodiment: With this structure, when the first gear 405 rotates, the third transmission rod 409, which is eccentrically rotatably connected to the outer wall of the first gear 405, will also rotate circumferentially with the rotation of the first gear 405. Then, the other first gears 405, which are eccentrically rotatably connected to the third transmission rod 409, will also rotate synchronously, thereby synchronously driving multiple fan blades 408 to rotate, increasing the efficiency of hot air recovery.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
