Description

Technical Field

[0001] The present invention belongs to the technical field of spinning forming devices, and more specifically, relates to a multifunctional spinning forming device for producing DTY yarns. Background Art

[0002] In today's textile industry, DTY yarn, as an important chemical fiber product, is widely used in many fields such as clothing, home textiles, and industrial textiles. Its market demand continues to grow. However, existing spinning and forming equipment has many drawbacks in the actual production process, which seriously restricts the improvement of DTY yarn quality and production efficiency. The current spinning forming device has been found to have at least the following technical problems: First, in the DTY yarn production process, the fiber cooling link is crucial. Traditional spinning and forming devices usually adopt a fixed-position, single-direction air cooling method. This cooling method causes large differences in the airflow intensity and temperature exposed to different parts of the yarn bundle, resulting in uneven cooling of the yarn bundle. For example, the windward and leeward sides of the yarn bundle cool at different rates, which in turn causes inconsistent internal fiber structure, rough surface, uneven thickness and other problems, seriously affecting the quality and performance of DTY yarn, making it difficult to meet the strict requirements of the high-end textile market for fiber quality.

[0003] Second, existing DTY yarn production equipment wastes energy in preheating the cooling air. Most equipment uses an independent heating system to preheat the cooling air, and does not fully utilize the waste heat generated during the production process. This not only consumes a large amount of electricity or other energy, increasing production costs, but also causes a waste of energy resources. At the same time, the heat inside the equipment cannot be effectively recycled, resulting in excessively high internal temperatures of the device, affecting the stability and service life of the equipment and reducing production efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a multifunctional spinning and forming device for DTY yarn production to solve the above problems.

[0006] Preferably, the hot and cold air switching mechanism includes a ventilation duct, an air pipeline is opened in the ventilation duct, the ventilation duct and the air exchange duct are fixedly installed, the spinning device body is provided with a spinning device heat dissipation port, the spinning device body is provided with an air inlet for connecting to the outside air, the spinning device body is provided with a cold air duct, the spinning device heat dissipation port is provided with a hot air duct, air ducts are opened inside the spinning device heat dissipation port and the hot air duct, a third transmission shaft is fixedly installed on the rotating ventilation duct, a third gear is fixedly installed on the third transmission shaft, a first transmission belt is meshed with a circumferential surface of the third gear, a second gear is meshed with the first transmission belt, and a second transmission shaft is fixedly installed on the second gear.

[0007] Preferably, the rotary blower mechanism includes a blowing outlet guard plate, which is rotatably connected to the spinning blowing nozzle, and a window for air circulation is provided on the blowing outlet guard plate, and the pipe in the ventilation duct is connected to the window provided on the blowing outlet guard plate, and a fourth gear is fixedly mounted on the second transmission shaft, and a second transmission belt is engaged with the circumferential surface of the fourth gear, and a first gear is engaged with the second transmission belt, and a first transmission shaft is fixedly mounted on the first gear, and the first transmission shaft is fixedly connected to the output shaft of the servo motor, the spinning blowing nozzle and the second transmission shaft are fixedly mounted, and a channel is provided in the feed pipe, and the channel provided in the feed pipe and the second transmission shaft are rotatably mounted.

[0008] Preferably, the stirring mechanism includes a wire outlet fixing plate, the wire outlet fixing plate is fixedly connected to the wire outlet, the spinning device body is provided with a wire guide disk, and the spinning device body is provided with a filament winding roller.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a hot and cold air switching mechanism is provided, which includes components such as a ventilation duct, a third transmission shaft, a third gear, a first transmission belt, a second gear and a second transmission shaft. When the turbofan starts to rotate, the motor drives the rotary ventilation duct to rotate, and the external cold air collected by the air inlet and the hot air collected by the heat dissipation outlet of the spinning device will be intermittently injected into the ventilation duct and then blown toward the yarn outlet. This design allows the yarn bundle to be continuously and alternately exposed to hot and cold air in a very short time. When exposed to hot air, the fiber molecular chain segments gain energy, enhance their mobility, and are easier to adjust and arrange; when exposed to cold air, the molecular chain segments are quickly cooled and fixed. In this way, the temperature changes of various parts of the fiber are uniform, which effectively reduces the internal structural differences and greatly improves the quality consistency, so that the produced DTY yarn has better performance in strength, elasticity, dyeing uniformity, etc., and can better meet the production needs of high-end textile products.

[0010] In the present invention, a rotating blower mechanism is provided, including a blower outlet guard plate, a first transmission shaft, a first gear, a second transmission belt, a fourth gear, a second transmission shaft, etc. When working, the wind blown by the turbofan blows toward the spinning blower nozzle along the ventilation duct, and the servo motor drives the first transmission shaft to rotate. Through the transmission of a series of gears and transmission belts, the spinning blower nozzle rotates around the outlet, which makes the cooling air blow toward the filament bundle from all directions and different angles, effectively eliminating the cooling dead corners. In traditional fixed-angle blowing cooling, some areas of the filament bundle are insufficiently cooled or over-cooled, resulting in quality defects. The rotating blower mechanism of the present invention makes the cooling conditions of various parts in the circumferential direction of the filament bundle tend to be consistent, which can effectively avoid problems such as uneven fiber thickness and strength differences caused by uneven cooling, and significantly improve the fiber quality.

[0011] In the present invention, a stirring mechanism is provided, which is composed of a wire outlet fixing plate, a stirring chamber and a stirring rod. The motor drives the stirring rod to rotate. The raw material enters the chamber formed by the stirring chamber and the wire outlet under the push of the spiral extrusion rod of the feed pipe. The stirring rod rotates at high speed in the chamber to fully stir the raw material. This design enables the spinning raw material and various additives to be fully mixed, ensuring that the various components in the fiber are evenly distributed. The evenly mixed raw materials can ensure that the fiber performance is stable and consistent. In subsequent processing such as stretching and weaving, the fiber performance is more stable, the defective rate is reduced, the continuity and stability of the production process are guaranteed, and the production efficiency is improved.

[0012] In the present invention, a hot and cold air circulation system is formed by components such as air exchange ducts, rotary ventilation ducts and turbo fans. The alternating hot and cold airflows can accelerate heat transfer. Under the switching action of the rotary ventilation ducts, the waste heat carried by the hot air is fully utilized. While cooling the filament bundles, the subsequent cooling air is preheated. Compared with traditional cooling methods, the present invention greatly reduces the additional energy consumption required for cooling air preheating. This not only saves a lot of energy costs for the enterprise, but also effectively reduces energy waste, conforms to the current green and environmentally friendly production concept, improves energy utilization efficiency, and enhances the sustainable development capabilities of the enterprise.

During operation, when the turbofan 37 starts to rotate, the motor drives the rotating ventilation duct 35 to start rotating, and the cold air and hot air collected by the air inlet 12 and the heat dissipation outlet 13 of the spinning device are intermittently injected into the ventilation duct 16 and then blown toward the silk outlet 34, so that the silk bundle can be continuously and alternately exposed to cold and hot air in a very short time, so that the temperature changes of various parts of the fiber are uniform, the internal structure differences are reduced, and the quality consistency is improved.

[0018] In this embodiment, Figure 3 、 Figure 5 and Figure 6 As shown, the rotary blower mechanism includes a blowing port guard plate 36, which is rotatably connected to the spinning blowing nozzle 31, and a window for air circulation is provided on the blowing port guard plate 36. The pipe in the ventilation duct 16 is connected to the window opened in the blowing port guard plate 36. A fourth gear 27 is fixedly mounted on the second transmission shaft 22, and a second transmission belt 29 is engaged with the circumferential surface of the fourth gear 27. The second transmission belt 29 is engaged with the first gear 24. The first transmission shaft 21 is fixedly mounted on the first gear 24, and the first transmission shaft 21 is fixedly connected to the output shaft of the servo motor. The spinning blowing nozzle 31 It is fixedly installed with the second transmission shaft 22, and the feed pipe 15 is provided with a channel. The channel opened in the feed pipe 15 is rotatably installed with the second transmission shaft 22. During operation, the wind blown by the turbofan 37 blows along the air path opened in the ventilation duct 16 to the spinning nozzle 31, and then the air outlet opened on the spinning nozzle 31 is used to blow and cool the filament bundle. The motor drives the spinning nozzle 31 to start rotating, so that the device rotates slowly around the central axis of the filament bundle, and the cooling wind blows to the filament bundle from all directions and different angles, effectively eliminating the cooling dead corners and making the cooling conditions of various parts in the circumferential direction of the filament bundle tend to be consistent.

[0019] In this embodiment, Figure 3 and Figure 6 As shown, the stirring mechanism includes a wire outlet fixing plate 32, which is fixedly connected to the wire outlet 34. The wire outlet fixing plate 32 is used to fix the wire outlet 34. The stirring chamber 39 and the wire outlet 34 are fixedly connected to form a chamber. During operation, the motor drives the stirring rod 33 to rotate, and the raw material flows through the feed pipe 15 and is squeezed into the chamber formed by the stirring chamber 39 and the wire outlet 34 by the spiral extrusion rod. The stirring rod 33 rotates in the chamber to make the raw materials mixed more evenly.

[0020] Working principle: In the first step, after the staff starts the device, the turbofan 37 starts to run, providing power for air flow. At the same time, the servo motor drives the first transmission shaft 21 to rotate. Since the first gear 24 is fixedly mounted on the first transmission shaft 21, the first gear 24 rotates synchronously therewith. The first gear 24 is engaged with the second transmission belt 29, and the second transmission belt 29 is engaged with the fourth gear 27. The fourth gear 27 is fixedly mounted on the second transmission shaft 22. Such a transmission structure enables the rotation of the first transmission shaft 21 to drive the second transmission shaft 22 to rotate. The spinning nozzle 31 is fixedly connected to the second transmission shaft 22. As the second transmission shaft 22 rotates, the spinning nozzle 31 starts to rotate around the outlet 34. During this process, the spinning nozzle 31 continuously blows out airflow, which evenly surrounds the filament bundle extruded from the outlet 34 during the rotation process. All parts of the filament bundle can fully contact the airflow, achieving more uniform cooling. This all-round cooling method can effectively avoid quality problems of the filament bundle caused by uneven cooling, thereby improving the quality of the fiber.

[0021] In the second step, during the rotation of the second transmission shaft 22, since it is fixedly connected to the second gear 25, it will drive the second gear 25 to rotate, the second gear 25 is meshed with the first transmission belt 28, and the first transmission belt 28 is meshed with the third gear 26. The third gear 26 is fixedly mounted on the third transmission shaft 23. Therefore, the rotation of the second transmission shaft 22 can drive the third gear 26 to rotate synchronously, thereby rotating the third transmission shaft 23. The third transmission shaft 23 is fixedly connected to the rotating ventilation duct 35, so the third transmission shaft 23 drives the rotating ventilation duct 35 to rotate synchronously, and the air is continuously switched during the rotation of the rotating ventilation duct 35. The source of gas in the exchange duct 38, when the opening of the rotary ventilation duct 35 is connected to the air inlet 12 or the heat dissipation port 13 of the spinning device, the temperature of the air inhaled by the turbofan 37 will change continuously, forming alternating hot and cold airflows, which blow toward the fibers extruded from the outlet 34, so that the temperature changes of various parts of the fibers are uniform. In this alternating hot and cold environment, the internal structure differences of the fibers are reduced, and the quality consistency is significantly improved. At the same time, the alternating hot and cold airflows can accelerate heat transfer, make full use of the waste heat generated during the operation of the device, further reduce the energy consumption required for cooling air preheating, and improve energy utilization efficiency.

[0022] In the third step, while the device is running, the raw materials enter the device through the feed pipe 15. The spiral extruder inside the feed pipe 15 rotates continuously under the drive of the motor, pushing the raw materials from one end of the feed pipe 15 to the other end, and finally allowing the raw materials to enter the stirring chamber 39. The second transmission shaft 22 is fixedly installed with the stirring rod 33. The second transmission shaft 22 drives the stirring rod 33 to rotate synchronously during the rotation process. The stirring rod 33 rotates at a high speed in the stirring chamber 39 to fully stir the raw materials entering the stirring chamber 39. During the stirring process, the spinning raw materials and various additives are fully mixed, making the performance of the fiber more stable and consistent. The stirring action of the stirring rod 33 can also maintain the material in a uniformly suspended or dissolved state, effectively preventing the raw materials from precipitating and stratifying, providing raw materials with stable quality for subsequent spinning production, and ensuring the high-quality production of DTY yarn.
