[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] The fiber spinning air cooling pre-setting device is a device for rapidly cooling the fiber spinning after drying.

[0021] After drying, fiber spinning usually needs to be cooled down quickly to complete shaping. Traditional air cooling cannot meet the cooling speed. Therefore, air cooling is often used to remove the heat from the fiber spinning surface and achieve rapid cooling. However, the existing air cooling method is to install an air outlet below or above the fiber layer, and the cold air has an unsatisfactory cooling effect on the fiber.

[0022] In response to the above technical issues, Figure 1 Shows the overall structural diagram of the fiber spinning air-cooling pre-forming device; Figure 2 A schematic cross-sectional view of a fiber spinning air-cooling preforming device is shown; Figure 3 A cross-sectional view of the conveyor roller 210 is shown; Figure 1-Figure 3 The fiber spinning air-cooling presetting device includes a housing 110, a fiber layer 120 is passed through the housing 110, and a plurality of groups of air-cooling components are equidistantly arranged along the path of the fiber layer 120 in the housing 110. The air-cooling components include:

[0023] Two sets of conveying rollers 210 are rotatably connected to the housing 110. A gap is formed between the two sets of conveying rollers 210 to allow the fiber layer 120 to pass through. One end of the conveying roller 210 extends through the housing 110 and is evenly distributed with a plurality of air ducts 211 around its axis. Each set of air ducts 211 is spaced apart and has air outlets 212.

[0024] A cover body 220 is disposed on the side wall of the housing 110. The cover body 220 and the housing 110 cooperate to form an air inlet bin, and the air duct 211 is connected to the air inlet bin;

[0025] An air blower 230 is installed on the housing 110 , and the output end of the air blower 230 is connected to the air inlet bin.

[0026] During use, when the two sets of conveying rollers 210 rotate in opposite directions to convey the fiber layer 120, the two sets of conveying rollers 210 will generate an extrusion force on the fiber layer 120, causing the fiber holes in the fiber layer 120 to open. At this time, the gas is transported to the air inlet bin by the blower 230 and discharged from the air outlet 212 through the air duct 211. It can pass through the fiber holes and take away the heat in the fiber layer 120 from the inside out, thereby improving the air cooling effect.

[0027] It should be noted that the counter-rotating of the two sets of conveying rollers 210 to extrude and convey the fiber layer 120 is a prior art technology and is not protected by this application. It can be easily implemented. For example, the ends of the two sets of conveying rollers 210 away from the air duct 211 are both connected to a gear 214, and the two sets of gears 214 are meshed with each other. By driving any set of conveying rollers 210 by the output motor, the two sets of conveying rollers 210 can be rotated in the opposite direction to convey the fiber layer 120.

[0028] Reference Figure 2 The fiber spinning air-cooled presetting device also includes a water-cooling component, which includes:

[0029] A closed pipe 240 passing through the two sets of conveying rollers 210, wherein the conveying rollers 210 and the closed pipe 240 are clearance-fitted;

[0030] The closed pipeline 240 is provided with a condenser 250 and a water pump 260 in sequence along the flow path of the liquid inside the closed pipeline 240.

[0031] During use, the closed pipe 240 with a clearance fit will fit tightly against the conveying roller 210, thereby reducing the temperature of the conveying roller 210. When cold air flows through the air duct 211, the conveying roller 210 will further cool the cold air in the air duct 211, thereby enhancing the cooling effect of the cold air on the fiber layer 120. The coolant is driven by the water pump 260 to circulate in the closed pipe 240, and the coolant that heats up after absorbing heat can be cooled by the condenser 250 to ensure the stability of the temperature of the coolant flowing through the conveying roller 210.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
