[0002] Yarn is a textile product made from various textile fibers processed into a certain fineness for weaving, rope making, thread making, embroidery, knitting, etc. After the yarn is formed into a linear shape, it needs to be cleaned to remove dust and other impurities. After cleaning, it also needs to be dried, so yarn drying equipment is required.
[0003] The prior art, disclosed in CN223192005U, describes a conductive drying device for spandex yarn. This device has a simple structure and is entirely exposed, resulting in a large amount of heat loss into the air during the drying process. This leads to low heat utilization. Furthermore, since the yarn passes directly through the drying area, the contact area between the heat and the yarn is small and the contact time is short, resulting in incomplete drying and easy retention of moisture in the yarn. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a conductive drying device for yarn.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn conduction drying device, comprising a box body that can be opened, with an inlet and an outlet on the left and right sides of the box body, respectively. Two vertical plates, arranged front and back, are fixedly connected inside the box body. The inlet and outlet are located between the two vertical plates. Each of the two vertical plates has several ventilation holes. A rotating tube is provided between the two vertical plates, and an annular groove is formed on the outer periphery of the rotating tube. Connecting tubes are movably connected to both ends of the rotating tube. A connecting pipe penetrates the adjacent vertical plate. An electric heating tube is fixedly connected to the inner wall of the front side of the box. A fan is fixedly connected to the connecting pipe on the rear side.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a yarn conduction drying device, including a box 1, which can be opened. An inlet and an outlet are respectively provided on the left and right sides of the box 1. Two vertical plates 14, arranged front and back, are fixedly connected inside the box 1. The inlet and outlet are both located between the two vertical plates 14. Several ventilation holes are provided on each of the two vertical plates 14. A rotating tube 11 is provided between the two vertical plates 14, and an annular groove is provided on the outer periphery of the rotating tube 11. Connecting tubes 12 are movably connected to both ends of the rotating tube 11, and the connecting tubes 12 penetrate adjacent... The vertical plate 14 is fixedly connected to the inner wall of the front side of the box 1. The fan 13 is fixedly connected to the rear connecting pipe 12. The water pump 9 is fixedly connected to the rear side of the box 1. A metal pipe 16 is provided between the rear vertical plate 14 and the box 1. Both ends of the metal pipe 16 pass through the box 1 and extend to the outside. The metal pipe 16 is connected to the water pump 9. A motor 8 is fixedly connected to the right side of the box 1. A rotating rod 7 is fixedly connected to the output end of the motor 8. The rotating rod 7 is located at the outlet. A movable rod 5 is movably connected to the left side of the box 1. The movable rod 5 is located at the outlet.
[0021] According to the overall structure of the device, connect the device to an external power source, place the yarn roll to be dried on the movable rod 5, start the heating element 15, open the chamber 1, pass the yarn end through the inlet into the chamber 1, and wind it once in the annular groove of the rotating tube 11. After the heating element 15 dries the yarn end, pass the yarn end through the outlet and wind it onto the rotating rod 7. Close the chamber 1, then start the fan 13 and motor 8, and start the water pump 9 to deliver cold water into the metal tube 16, keeping the metal tube 16 at a relatively low temperature compared to the inside of the chamber 1. The fan 13 drives the airflow inside the rotating tube 11, drawing the hot air between the front vertical plate 14 and the chamber 1 into the rotating tube 11, and then sending it into the space between the rear vertical plate 14 and the chamber 1. The air between the rear vertical plate 14 and the box 1 is squeezed and flows through the vent to the space between the front vertical plate 14 and the box 1. It is then heated again by the electric heating tube 15, thus forming a circulating hot airflow. At the same time, the hot air heats the rotating tube 11 as it passes through it, thereby drying the yarn evenly. Meanwhile, the motor 8 drives the rotating rod 7 to rotate, pulling the dried yarn out from the outlet and winding it up. The moisture in the yarn is heated and forms steam. As the hot air flows, the steam flows to the metal tube 16. When the steam comes into contact with the low temperature of the metal tube 16, it condenses into water droplets on the surface of the metal tube 16 and falls to the bottom of the box 1 to accumulate, thus preventing the steam from flowing back between the two vertical plates 14 and ensuring that the yarn is completely and thoroughly dried.
[0022] like Figure 2 As shown, support plates 3 are fixedly connected to both the left and right sides of the housing 1. The motor 8 is fixedly connected to the rear side of the support plate 3. The rotating rod 7 and the movable rod 5 are movably connected to the front side of the support plate 3. The front end of the rotating rod 7 and the movable rod 5 is provided with a baffle 4. The baffle 4 includes a fixed plate 401 and a movable plate 402. The fixed plate 401 is fixedly connected to the housing 1. The movable plate 402 is movably connected to the fixed plate 401 through a hinge. A slot is opened on the movable plate 402. The rotating rod 7 and the movable rod 5 are inserted into the slot. A spring 403 is fixedly connected between the movable plate 402 and the housing 1.
[0023] The movable rod 5 and the rotating rod 7 are supported by the support plate 3 and the baffle 4. The baffle 4 is formed by the fixed plate 401 and the movable plate 402. When the movable plate 402 is flipped outward, the restriction on the movable rod 5 and the rotating rod 7 can be removed, so that the yarn roll can be placed on the movable rod 5 and the dried yarn roll can be removed from the rotating rod 7. The spring 403 provides tension to hold the movable plate 402 to prevent the movable plate 402 from deflecting during operation and affecting the yarn feeding and take-up.
[0024] like Figure 3 The metal pipe 16 shown is provided in several parts. The water pump 9 has a water supply pipe 10 fixedly connected to both the inlet and outlet. The two ends of the several metal pipes 16 are fixedly connected to the adjacent water supply pipes 10 respectively.
[0025] The metal pipe 16 is connected to the water pump 9 at both ends by the water supply pipe 10 to form a circulation loop. The water pump 9 pumps the cold water in the metal pipe 16 to circulate, maintaining the metal pipe 16 at a low temperature relative to the inside of the box 1.
[0026] like Figure 2 The top of the box 1 shown is open, and the top of the box 1 is provided with a cover plate 2. The rear side of the cover plate 2 is movably connected to the box 1 by a hinge, and the front side of the cover plate 2 is fixed to the box 1 by bolts. A sealing strip that is tightly attached to the bottom of the cover plate 2 is fixedly connected to the box 1.
[0027] The cover plate 2 can be easily loosened by bolts, the chamber 1 can be opened, the yarn to be dried can be placed on the device, then the cover plate 2 can be closed, the bolts can be tightened to fix the cover plate 2, and the chamber 1 can be closed. The operation is simple and quick.
[0028] like Figure 4 A level gauge 17 is fixedly connected inside the box 1 shown. The level gauge 17 is located between the rear vertical plate 14 and the box 1. The dial of the level gauge 17 extends from the top of the box 1 to the outside. A drain pipe is fixedly connected to the bottom of the box 1, and a drain valve is installed on the drain pipe.
[0029] The water level gauge 17 is used to detect the water accumulated in the tank 1. When the water level is detected to be close to the bottom of the connecting pipe 12, the drain valve is opened to allow the accumulated water to be discharged from the drain pipe.
[0030] like Figure 3 The inlet and outlet ports shown are provided with several, the rotating tube 11 is provided with several annular grooves, the rotating rod 7 and the movable rod 5 are provided with partition plates 6, the partition plates 6 are provided with threaded holes, and the rotating rod 7 and the movable rod 5 are provided with external threads that match the threaded holes on their peripheral sides.
[0031] The areas on the movable rod 5 and the rotating rod 7 are separated by the partition 6, and multiple partitions 6 can be quickly assembled by threaded connection, so that multiple yarns can be placed and wound at the same time. Several inlets, outlets and annular grooves make the multiple yarns independent of each other and prevent them from getting tangled. Thus, the drying of multiple yarns can be operated at the same time.
[0032] Working principle: When in use, connect the device to an external power source, place the yarn roll to be dried on the movable rod 5, start the heating element 15, open the chamber 1, and feed the yarn end through the inlet into the chamber 1, winding it once in the annular groove of the rotating tube 11. After the heating element 15 dries the yarn end, pass the yarn end through the outlet and wind it onto the rotating rod 7. Close the chamber 1, then start the fan 13 and motor 8, and start the water pump 9 to circulate the cold water in the metal tube 16. The fan 13 drives the hot air inside the chamber 1 through the rotating rod 7. The rotating tube 11 circulates, and the hot air passing through the rotating tube 11 heats the rotating tube 11, thereby drying the yarn evenly. At the same time, the motor 8 drives the rotating rod 7 to rotate, pulling the dried yarn out from the outlet and winding it up. The moisture in the yarn is heated and forms steam. As the hot air flows, the steam flows to the metal tube 16. When the steam comes into contact with the low temperature of the metal tube 16, it condenses into water droplets on the surface of the metal tube 16 and falls to the bottom of the box 1 to accumulate. When the liquid level is high as observed by the liquid level gauge 17, the drain valve is opened to drain the water.
