Description

Technical Field

[0001] This utility model relates to the technical field of spinning cooling devices, and in particular to a gas mist liquid nitrogen composite cooling device for spinning. Background Technology

[0002] The aerosol-liquid nitrogen composite cooling device for spinning is a highly efficient cooling equipment specifically designed for the spinning process. This device combines the advantages of aerosol cooling and liquid nitrogen cooling, achieving rapid and uniform cooling of the spun fibers through the uniform heat dissipation of the aerosol and the extremely low temperature characteristics of liquid nitrogen. Aerosol cooling initially lowers the fiber temperature, while liquid nitrogen further and rapidly solidifies the fiber structure, improving the fiber's strength and toughness. This composite cooling method not only improves production efficiency but also significantly enhances the fiber's quality stability and reduces the defect rate.

[0003] The cooling mechanism of existing cooling devices usually adopts air cooling or water cooling alone. The cooling rate of traditional processes is difficult to exceed 10^7 K / S. At the same time, the crystallinity of spinning is high, usually greater than 0.8%, and the surface energy is higher than 15%. Traditional spinning processes have "necking" defects, making it difficult to meet the standards of high-quality spinning. Meanwhile, the residual stress reaches more than 200 MPa.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment: an aerosol-liquid nitrogen composite cooling device for spinning, including a worktable 1, with supporting legs 11 at the bottom for raising the worktable 1, and a cooling assembly at the top of the worktable 1. The cooling assembly includes a limiting block 31, with a spinning channel 311 at the top of the limiting block 31 for accommodating spinning. Liquid nitrogen tanks 33 for spinning cooling are respectively attached to the left and right sides of the limiting block 31. A water tank 32 is provided above the limiting block 31, and an aerosol nozzle 322 for spraying water mist into the spinning channel 311 is provided at the bottom of the water tank 32 corresponding to the position of the spinning channel 311. A winding assembly is provided at the top of the worktable 1 corresponding to the front of the cooling assembly. The winding assembly includes... The spiral tube 21 includes an outlet end face 211 and an inlet end face. The outlet end face 211 faces away from the cooling component, and the inlet end face faces closer to the cooling component. The filaments in the spinning channel 311 can enter the spiral tube 21. Through the cooperation of the water tank 32 and the aerosol nozzle 322 in the cooling component, aerosol is sprayed into the spinning channel 311 to cool the filaments that need to be cooled. At the same time, the liquid nitrogen tanks 33 attached to the left and right sides of the limiting block 31 can also cool the filaments in the spinning channel 311, thus constructing an aerosol-liquid nitrogen composite cooling system. The cooling speed exceeds 10^7 K / S, inhibits crystallization, reduces surface energy by 15%, and eliminates filament necking defects.

[0023] Please see Figure 1 - Figure 4 In this embodiment, the bottom of the limiting block 31 is provided with two plates 302 on the front and rear sides respectively. The bottom of the two plates 302 is provided with one plate 301 on the left and right sides respectively, which is connected to the top of the worktable 1. The top of the two plates 302 is provided with three plates 303 on the left and right sides of the limiting block 31. The top of the three plates 303 supports the water tank 32. The top of the water tank 32 is provided with a water inlet 321 for filling the water tank 32. The two plates 302 are lifted by the one plate 301, raising the height of the limiting block 31. The three plates 303 support the water tank 32, which facilitates the aerosol nozzle 322 to spray the spinning nozzle into the spinning channel 311. The liquid nitrogen tank 33 is away from the limiting block 31. One side is provided with a liquid nitrogen inlet pipe 331 and a liquid nitrogen outlet pipe 332. The distance between the liquid nitrogen outlet pipe 332 and the workbench 1 is greater than the distance between the liquid nitrogen inlet pipe 331 and the workbench 1. Liquid nitrogen can be easily filled into the liquid nitrogen tank 33 through the liquid nitrogen inlet pipe 331. The liquid nitrogen in the liquid nitrogen tank 33 can be discharged from the liquid nitrogen outlet pipe 332, increasing the cooling efficiency. The spiral tube 21 is provided with a positioning block 2 to limit the spiral tube 21. The right side of the positioning block 2 is provided with a vertical plate 22 connected to the top of the workbench 1. The left side of the positioning block 2 is provided with a weight reduction groove 20. The weight reduction groove 20 reduces the weight of the positioning block 2, making the vertical plate 22 more stable on the top of the workbench 1.

[0024] Please see Figure 2 - Figure 5In this embodiment, a bonding plate 231 is provided on the left side of the positioning block 2. A right-protruding pressure post 232 is provided on the side of the bonding plate 231 facing the positioning block 2. The outer side of the pressure post 232 is coated with adhesive. This adhesive coating allows the pressure post 232 to be pressed tightly against the spiral tube 21. The radially outward adhesive coating of the pressure post 232 prevents scratches from forming on the surface of the spiral tube 21, increasing its aesthetic appeal. It also facilitates the fixation of the spiral tube 21, enhancing its overall performance. For stability, a lower roller 42 and an upper roller 43 are provided between the cooling assembly and the winding assembly to drive the spinning movement. The axes of the lower roller 42 and the upper roller 43 are parallel. Support plates 41 are provided on the left and right sides of the lower roller 42. A motor 412 for driving the lower roller 42 to rotate is provided on the side of one of the support plates 41 away from the lower roller 42. The top of the support plate 41 has a downwardly recessed receiving position 411. The left and right sides of the upper roller 43 have cylinders 431 that can be placed in the receiving position 411. The top is provided with a top plate 44. A pressure block 45, tangent to the cylinder 431, is provided above the cylinder 431 within the receiving position 411. A guide rod 451 is provided on the top of the pressure block 45. A guide hole 441 for the guide rod 451 to pass through is provided on the top of the top plate 44. A spring 452 is fitted onto the outer diameter of the guide rod 451. The top of the spring 452 is in contact with the bottom of the top plate 44, and the bottom of the spring 452 is in contact with the top of the pressure block 45. The pressure block 45 is limited by the receiving position 411 and the cylinder 431. The pressure block 45 can only move up and down. The spring 452 can drive the pressure block 45 to press the cylinder 431, reducing the jumping of the cylinder 431. The spring 452 can absorb vibration and prevent damage to the upper roller 43 and lower roller 42 or breakage of the spinning. The motor 412 can provide the force for the spinning to move, so that the spinning can enter the spiral tube 21. A straight tube 5 for receiving the spinning is connected to the front side of the inlet end through a flange. The straight tube 5 facilitates the receiving of the spinning, so that the spinning can smoothly enter the spiral tube 21.

[0025] During operation, the flexible filaments enter the spinning channel 311. Water from the water tank 32 is sprayed from the aerosol nozzle 322 to cool the filaments. Simultaneously, the liquid nitrogen tank 33, which is attached to the limiting block 31, absorbs the heat from the filaments for cooling. The filaments pass between the lower roller 42 and the upper roller 43. The motor 412 drives the lower roller 42 to rotate, moving the filaments forward. The upper roller 43 presses against the filaments and rotates accordingly. Immediately after passing through the lower roller 42 and the upper roller 43, the filaments enter the straight tube 5. It is necessary to ensure that the filaments can directly enter the straight tube 5. The relative position of the spiral tube 21 and the positioning block 2 can be adjusted appropriately to facilitate a certain degree of adjustment of the position of the straight tube 5. The outer diameter of the lower roller 42 and the upper roller 43 can also be provided with concave rings corresponding to spinning, which facilitates the positioning of the spinning. The spinning that enters the straight tube 5 can re-enter the spiral tube 21 and coil inside the spiral tube 21 to form a spiral structure, which is convenient for storage. The bonding plate 231 can rotate relative to the positioning block 2, which facilitates the pressing column 232 to press on the spiral tube 21 and increase the stability of the spiral tube 21. The spraying principle of the aerosol nozzle 322, the water inlet 321 connected to the water pipe, the liquid nitrogen inlet pipe 331 connected to the liquid nitrogen feed pipe, the liquid nitrogen outlet pipe 332 connected to the liquid nitrogen discharge pipe, and the liquid nitrogen production method are all existing technologies. At the same time, the method of driving the rotation by the motor 412 is also well known to those skilled in the art.

[0026] Through the above steps, the water tank 32 and the mist nozzle 322 in the cooling assembly work together to spray mist into the spinning channel 311 to cool the spinning process that needs to be cooled. At the same time, the liquid nitrogen tanks 33 attached to the left and right sides of the limiting block 31 solve the problem of low spinning performance caused by the use of traditional cooling methods in the existing cooling devices.
