Description

Technical Field

[0001] The present invention relates to the field of polyester fiber preparation, and particularly to a preparation device and method for a porous structure cool-sensation functional composite polyester fiber. Background Art

[0002] The porous structure cool-sensation functional composite polyester fiber is a new type of functional fiber obtained by compounding a cool-sensation functional material (such as mineral particles, phase change microcapsules or heat-conducting fillers) with a polyester matrix and introducing a controllable porous structure. Its porous structure can enhance the air permeability and moisture absorption and sweat discharge ability of the fiber, while the cool-sensation functional material endows the fabric with contact cool-sensation and long-term temperature control performance through heat conduction or heat buffer effect. During the preparation process, stirring and mixing equipment and heating equipment are the core process equipment: for example, a reaction kettle is equipped with jacket heating (60 - 80°C) and a mechanical stirring paddle for mixing a polyester solution and a pore-forming agent (such as a water-soluble salt); Since the temperature during the mixing of the polyester solution and the pore-forming agent is not heated high, the traditional jacket heating only transfers heat through the outer periphery of the container, resulting in heat lag in the inner layer of the material and the dead corner area at the bottom, forming a temperature gradient, which affects the uniform dispersion of the functional material. Moreover, the single-form stirring is prone to generating a laminar flow region and is difficult to break the agglomeration of the functional material, and the uneven heating further exacerbates the local melt viscosity difference, leading to an imbalance in the shear force distribution, and ultimately reducing the consistency of the porous structure and the stability of the cool-sensation function.

[0003] Therefore, it is necessary to propose a preparation device and method for a porous structure cool-sensation functional composite polyester fiber to solve the above problems. Summary of the Invention

A spring 20 sleeved in the depression is arranged on the side of the sliding ring 19 close to the nozzle 11, and the nozzle 11 is horizontally arranged in the initial state of the spring 20.

[0022] In combination with an embodiment of the present invention Figures 1-3 andFigure 8 Shown. In order to realize the rotation of the rotating shaft 7 and the lifting of the inner rod 8, a driving source for driving the rotation of the rotating shaft 7 and the lifting of the inner rod 8 is provided at the upper end of the housing 1. At the same time, a transmission box 2 is also provided at the upper end of the housing 1. The driving source is arranged in the transmission box 2. The driving source includes a worm 32 arranged on the outer wall of the upper end of the rotating shaft 7. A worm wheel 31 meshing with the worm 32 is rotatably arranged at one end of the top of the housing 1. A driven wheel 33 is arranged on the outer wall of the upper end of the rotating shaft 7. A reduction motor 5 is arranged at one end of the top of the housing 1. The output end of the reduction motor 5 is provided with a driving wheel 34 driven by the reduction motor 5 and meshing with the driven wheel 33. An eccentric wheel 6 driven to rotate by the worm wheel 31 is arranged on the side of the worm wheel 31. A movable ring 29 is movably sleeved on the outside of the eccentric wheel 6. A second traction arm 30 is fixed to the upper end of the movable ring 29. A first traction arm 4 corresponding to the second traction arm 30 is movably arranged at one end of the top of the housing 1. One end of the first traction arm 4 is movably arranged on the inner wall of the transmission box 2. The upper end of the second traction arm 30 is movably connected to the side wall of the first traction arm 4. A rotating rod 28 is rotatably arranged at the top of the inner rod 8. One end of the first traction arm 4 is movably connected to the side wall of the rotating rod 28.

[0023] The specific operating principle is: the raw material is injected into the shell 1, and the driving wheel 34 is driven to rotate by the reduction motor 5, and the driving wheel 34 drives the rotating shaft 7 and the inner rod 8 to rotate synchronously through the driven wheel 33. Since the worm wheel 31 is meshed with the worm 32, the worm wheel 31 will be driven to rotate through the worm 32 when the rotating shaft 7 rotates, and the worm wheel 31 will drive the eccentric wheel 6 to rotate. The eccentric wheel 6 continuously pulls the first traction arm 4 through the movable ring 29 and the second traction arm 30. One end of the first traction arm 4 continuously pulls the inner rod 8 through the rotating rod 28, and then the inner rod 8 will rise and fall reciprocatingly while following the rotation of the rotating shaft 7. When the rotating shaft 7 and the inner rod 8 rotate, the first paddle 9, the second paddle 10, and the stirring plate 12 will be driven to rotate. The second paddle 10 transports the upper material downward, and the first paddle 9 transports the bottom deposited material upward, and the stirring plate 12 stirs and breaks it up. Due to the action of centrifugal force, the nozzle 11 drives the outer cylinder 14 to move outward, and the outer cylinder is 14 drives the nozzle 11 to rotate vertically, and at the same time the slip ring 19 compresses the spring 20. At this time, the multiple nozzles 11 are all in a vertical state and are arranged along the height direction of the inner wall of the shell 1. When the inner rod 8 moves up and down, it will drive the stirring plate 12 and the nozzle 11 to move as a whole through the fixed base frame 13. Due to the action of the guide shaft 26 and the first guide groove 16, the piston rod 25 continuously moves back and forth horizontally. Due to the action of the second one-way valve 24 and the first one-way valve 23, when the piston rod 25 moves toward the direction of the nozzle 11, the material in the piston cylinder 21 can be sprayed out to the periphery of the shell 1 through the nozzle 11. When the piston rod 25 moves toward the direction of the rotating shaft 7, the suction pipe 22 sucks the middle material into the piston cylinder 21, waiting for the subsequent spraying to the periphery through the nozzle 11. This cycle improves the reaction effect and efficiency. Moreover, when the inner rod 8 moves, it will also drive the first paddle 9 to move longitudinally, reducing the deposition in the bottom dead corner. At the same time, the lateral transportation of the nozzle 11 is also beneficial to the cooling of the cooling coil 3. After completion, the speed of the reduction motor 5 is reduced, and then the speed of the rotating shaft 7 and the inner rod 8 is reduced, the centrifugal force on the nozzle 11 is reduced, the spring 20 is gradually reset, and the outer cylinder 14 drives the nozzle 11 to gradually rotate to a horizontal position. As the discharge progresses, the rotating shaft 7 drives the inner rod 8 to rotate slowly, and the inner rod 8 still reciprocates up and down. When the piston cylinder 21 moves upward, the suction tube 22 fills the interior of the piston cylinder 21 with liquid or gas, and when the inner rod 8 moves downward, the liquid or gas in the piston cylinder 21 is sprayed out through the nozzle 11, and the nozzle 11 moves downward when spraying. Therefore, as the discharge progresses, the nozzle 11 can continuously blow down the attachments on the inner wall of the shell 1, reducing attachments and facilitating subsequent cleaning.
