Drying is an important step, mainly used to adjust the moisture regain of the yarn to ensure the quality and stability of the yarn. As shown in a yarn drying device for yarn production disclosed on the existing patent website (public announcement number CN221197942U), this type of yarn drying device drives the dryer to move by a servo motor, and through the cooperation of the ventilation pipe and the bellows, the hot air in the inner cavity of the device box is transported to the surface of the yarn body.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution for a yarn drying device for yarn production: a yarn drying device for yarn production, comprising a drying box 1, wherein a first traction wheel group 6, a second traction wheel group 7, and a third traction wheel group 8 are sequentially arranged inside the drying box 1 from left to right. By sequentially arranging the yarn group and hanging it on the traction wheels of the first traction wheel group 6, the second traction wheel group 7, and the third traction wheel group 8, and utilizing the traction wheels to perform line traction on the yarn group, the yarn group can be evenly arranged for drying, thereby ensuring efficient drying.

[0024] A tensioning mechanism 2 is installed on one side of the drying box 1, facing the first traction wheel group 6 and the second traction wheel group 7. The tensioning mechanism 2 includes a lifting screw sleeve 21 installed on the drying box 1, and a lifting screw rod 22 is installed inside the shaft sleeve of the lifting screw sleeve 21. A lifting handwheel 23 is installed on the top of the shaft rod of the lifting screw rod 22, and an arm truss 26 is connected to the bottom end of the shaft rod of the lifting screw rod 22. The shaft sleeves of the lifting screw sleeve 21 are symmetrically installed on both sides of the lifting sleeve 24 on the drying box 1, and the shaft sleeve of the lifting sleeve 24 is slidably connected to a lifting guide rod 25 fixedly connected to the arm truss 26. By rotating the lifting handwheel 23, the lifting screw rod 22 is driven to rise and fall along the lifting screw sleeve 21, and then the arm force of the lifting sleeve 24 and the lifting guide rod 25 is used to push the arm truss 26 downward as a driving source to push the tensioning wheel group 29 downward to tension and traction the yarn group.

[0025] Both ends of the base frame of the arm truss 26 are equipped with rotating shaft seats 28, and a tensioning wheel group 29 is installed between the two opposite sets of rotating shaft seats 28. The arm truss 26 and the rotating shaft seats 28 are elastically connected through a spring seat 27. When the arm truss 26 moves downward, it drives the tensioning wheel group 29 to elastically tension the yarn group. On the one hand, it keeps the yarn group in a suitable tensioning state to improve the smoothness of yarn transportation. On the other hand, its tensioning force is used to tension and squeeze the moisture in the yarn group to squeeze out the moisture to reduce the subsequent drying intensity.

[0026] A hot air drying mechanism is installed on the other side of the drying box 1, facing the second traction wheel group 7 and the third traction wheel group 8. The hot air drying mechanism includes a hot air box 3 installed on the drying box 1. A blower 4 is installed on the upper end of the hot air box 3, and a heater 9 is installed inside the hot air box 3 facing the vent of the blower 4. A plurality of drying air ducts 5 are arranged at the bottom of the hot air box 3. The plurality of drying air ducts 5 are arranged at equal intervals, and each group of drying air ducts 5 is U-shaped. Closed structure, the bottom tube arrangement of the drying air duct 5 is installed with multiple groups of first hot air nozzles 10, and the top tube arrangement of the drying air duct 5 is installed with multiple groups of second hot air nozzles 11. By controlling the combined operation of the blower 4 and the heater 9, the hot air is diverted and blown into the drying air duct 5, and then the first hot air nozzle 10 on the drying air duct 5 is blown upward and the second hot air nozzle 11 is blown downward to perform synchronous hot air drying on the front and back sides of the yarn group flowing through the route to ensure comprehensive hot air drying.

[0027] The working principle of the present invention is as follows: when the yarn drying device is used to dry the yarn group, the yarn group is sequentially arranged and hung on the traction wheels of the first traction wheel group 6, the second traction wheel group 7, and the third traction wheel group 8, and the traction wheels are used to separate and pull the yarn group so that the yarn group is evenly arranged for drying;

[0028] Then, the lifting hand wheel 23 in the tensioning mechanism 2 is rotated to drive the lifting screw 22 to lift and rotate along the lifting screw sleeve 21, and then the arm force of the lifting sleeve 24 and the lifting guide rod 25 is used to guide the arm force truss 26 downward. When the arm force truss 26 moves downward, it drives the tensioning wheel group 29 to elastically tension the yarn group, so that the yarn group is kept in a suitable tension state. At the same time, the tensioning force can be used to squeeze the moisture in the yarn group to squeeze out the moisture, thereby reducing the subsequent drying intensity.

[0029] Furthermore, during the continuous conveying process of the yarn, the hot air is diverted and blown into the drying air duct 5 by controlling the combined operation of the blower 4 and the heater 9, and then the first hot air nozzle 10 on the drying air duct 5 is used to blow upward and the second hot air nozzle 11 is used to blow downward to perform synchronous hot air drying on the front and back sides of the yarn group flowing through the route, so as to ensure the comprehensiveness of the hot air drying, improve the yarn drying efficiency, and ensure the yarn drying quality.

[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
