[0003] Domestic utility model patent application number 201920157678.9 discloses a monofilament network air jet structure for a texturing machine, including an air jet device and a traction device disposed above the air jet device. A paralleling device is disposed between the air jet device and the traction device. A support frame for fixing the paralleling device is disposed on one side of the paralleling device. The paralleling device includes a cylindrical support base and a paralleling unit disposed above the support base. The upper surface of the support base has a funnel-shaped placement hole that penetrates the support base along its thickness direction. The upper end diameter of the placement hole is larger than the lower end diameter. The paralleling unit is shaped like a frustum and placed in the placement hole. The upper surface of the paralleling unit has a thread feeding hole along its thickness direction. Several thread feeding holes are evenly distributed along the center of the end face of the paralleling unit, parallel to the side of the paralleling unit. A vertical through hole is connected to the lower end of the thread feeding hole.

[0015] Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Normal temperature and pressure air is pressurized to 4 kg / m³ by a centrifugal air compressor. This typically involves two stages of compression. The first stage produces 1.5 kg / m³ primary compressed air at 100°C, which is then cooled by a first-stage cooler to 1.5 kg / m³ at 40°C. The second stage produces 4 kg / m³ at 110°C, and finally, an aftercooler cools it to 4 kg / m³ at 45°C for use by terminal equipment. Now, to avoid water contamination in the air supplied to terminal equipment, the aftercooler has been eliminated, and the 4 kg / m³ 110°C compressed air is directly discharged for supply. Research shows that the 110°C compressed air, after traveling through tens of meters of pipeline to the texturing machine nozzle, still maintains approximately 72°C. This high-temperature compressed air contains no liquid water and does not alter the physical properties of the product, effectively solving the problem of water contamination in the original network's compressed air supply.

[0018] 2. The compressed air that travels through a pipeline of several tens of meters to the nozzle of the texturing machine is still at a high temperature. To prevent condensation during the transportation process, a water supply device connected to the delivery pipe circulates the medium at a temperature of 45°C, which converts the high temperature in the air into heat again. This reduces the impact of the heat in the compressed air on the spinneret network without producing condensation. Attached Figure Description

[0024] This specific embodiment is a structure for preventing the textured network yarn from containing water.

[0025] The original compressed air compressor output temperature is about 45℃. It is transported to the texturing machine through a pipeline of tens of meters. However, once the pipeline is set up in the workshop or outdoors, when the ambient temperature is <45℃, the compressed air will be cooled down, causing condensed liquid water in the air to precipitate out. The liquid water will be sprayed out from the network nozzle of the machine with the compressed air, which will seriously affect the network quality of the texturing wire and produce defective products.

[0026] Its structural diagram is as follows Figures 1-4 As shown. A structure for preventing moisture in texturing network yarn includes a texturing frame 1, with multiple sets of raw material rollers 5 mounted on the top of the texturing frame 1, and a centrifugal air compressor 2 mounted on one side of the texturing frame 1. The centrifugal air compressor 2 is equipped with two sets of air consumption terminals 21, through which compressed air is discharged.

[0027] Multiple sets of network nozzles 4 are installed on the texturing frame 1. A cooling chamber 14 is provided inside the texturing frame 1 at the location of the network nozzle 4. A guide roller 11 is fixedly installed on the top of the texturing frame 1 at the location of the network nozzle 4. A feed roller 12 is fixedly installed on one side of the network nozzle 4. A guide port 15 is provided on the texturing frame 1 at the bottom of the feed roller 12. The filaments that have been spun are guided by the feed roller 12 and conveyed downward through the guide port 15 for further texturing. A filament discharge hole 17 is provided on the texturing frame 1 at the bottom of the guide roller 11. An auxiliary roller 19 is installed inside the texturing frame 1 at the location of the network nozzle 4. A spray hole 18 is provided on the texturing frame 1 between the auxiliary roller 19 and the network nozzle 4. Material fed downwards by the raw material roller 5 is oriented by the guide roller 11, passes through the yarn discharge hole 17 and the nozzle 18, is guided out by the auxiliary roller 19, and is ejected by the network nozzle 4. During the ejection process from the network nozzle 4, compressed air ejected from the air jet 13 assists in the yarn spinning process, increasing the yarn network. A drain port 141 is provided on the texturing frame 1 located between the cooling chamber 14 and the network nozzle 4. A guide plate 16 is installed inside the texturing frame 1 at the bottom of the yarn discharge hole 17. The guide plate 16 guides the compressed air ejected from the drain port 141.

[0028] A conveying pipe 3 is installed through the cooling chamber 14. An air outlet 13 is located inside the texturing frame 1 at the location of the cooling chamber 14. The air supply end 21 is connected to the air outlet 13 via a connecting pipe. Through the connection of the air supply end 21 and the air outlet 13, air compressed by the centrifugal air compressor 2 is discharged. Compressed air is the necessary medium for texturing machine production and is used in conjunction with the network nozzle 4 to increase the network of the yarn. Normal temperature and pressure air is pressurized to 4 kg of compressed air by the centrifugal air compressor 4. Generally, it undergoes two stages of compression. After the first stage compression, 1.5 kg of primary compressed air at 100°C is obtained from normal temperature and pressure. This primary compressed air is then cooled by the first stage cooler to obtain 1.5 kg of compressed air at 40°C. The second stage compression then yields 4 kg of compressed air at 110°C. Finally, the compressed air is cooled by the aftercooler to obtain 4 kg of compressed air at 45°C for use by the terminal equipment. To avoid water contamination in the air used in the terminal equipment, the aftercooler has been eliminated, and 4 kg of 110°C compressed air is directly discharged for supply. Research shows that the 110°C compressed air, after passing through a pipeline of several tens of meters, still maintains a temperature of around 72°C when sprayed through the texturing machine nozzle. This high-temperature compressed air contains no liquid water and does not alter the physical properties of the product, effectively solving the problem of water contamination in the compressed air used in the original network. The compressed air remains at a high temperature after passing through the pipeline to the texturing machine nozzle, preventing condensation during transport. An external water supply device connected to the delivery pipe 3 circulates the medium at 45°C, further converting the high temperature in the air into heat, thus reducing the impact of heat in the compressed air on the spinneret network without producing condensate.

[0029] Example 1: When the impeller inside the centrifugal air compressor 2 rotates at high speed, a low-pressure zone is formed at the center of the impeller, drawing in fresh air from the outside. The gas is accelerated by the impeller blades and thrown out radially. After leaving the impeller, the gas enters the diffuser, where its velocity is gradually reduced while its pressure increases. By eliminating the aftercooler and performing multiple stages of compression, the high-temperature compressed air is directly discharged for supply. The compressed air, combined with the network nozzle 4, is sprayed out to treat the filaments, increasing the network of the filaments while solving the problem of water carried by the compressed air in the original network.

[0030] Example 2: Compressed air is introduced into the cooling chamber 14 through the jet nozzle 13 to avoid condensation during transportation. The medium at 45°C is circulated by a water supply device connected to the external delivery pipe 3, which converts the high temperature in the air into heat again, thereby reducing the impact of the heat in the compressed air on the spinneret network.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
