In the present invention, a buoyancy control box is disposed below the oil storage tank. A belt drive assembly is rotatably disposed on one side of the buoyancy control box. A first meshing portion that moves up and down is engaged on one side of the belt drive assembly. The belt drive assembly is coupled to the upper oil pulley assembly for transmission. A flow guide assembly is disposed between the oil storage tank and the upper oil pulley assembly. A flow guide assembly is rotatably disposed on the flow guide assembly. A buoyancy transmission assembly that meshes with the meshing assembly is longitudinally slid on the buoyancy control box.

Description

Technical Field

[0001] The invention belongs to the technical field of polymer fibers, and in particular relates to a production process of regenerated antibacterial and flame-retardant polyester DTY fibers. Background Art

[0002] Currently, most of the antibacterial and flame-retardant polyester fibers on the market are virgin fibers, which consume petroleum resources during the production process. After being discarded, the virgin fibers will produce a large amount of waste polyester that cannot be effectively treated, which can easily cause environmental pollution and energy loss. Therefore, it is necessary to develop recycled antibacterial and flame-retardant polyester fibers to improve the environmental pollution problem caused by waste polyester.

[0003] In the existing technology, the POY texturing production DTY process includes steps such as deformation by heating in a deformation hot box, twisting, networking, and shaping in a shaping hot box. The cooling plate is an important equipment component required for fiber texturing production. The function of the cooling plate is to allow the yarn to enter the cooling plate after high-temperature plasticization in the hot box, and to dissipate the internal heat to the surrounding environment by utilizing the large surface area of ​​the cooling plate to dissipate the internal heat, thereby fixing the thermal deformation of the yarn and reducing its thermoplasticity. At the same time, the fiber needs to be oiled after cooling.

[0004] While traditional V-grooved cooling plates can achieve a certain degree of heat dissipation and cooling for fibers, they are ineffective. Furthermore, existing fiber oiling processes often involve directly pulling the fibers through an oil tank. While this direct oiling process can achieve fiber oiling, it can easily lead to uneven oil coverage on the fiber surface. To address this, we have developed a production process for recycled antibacterial and flame-retardant polyester DTY fibers to address these issues. Summary of the Invention

[0016] 2. The present invention uses an air supply device to transport air flow along the main air duct and each air inlet duct to each air flow duct. Part of the air flow entering the air flow duct enters the interior of the lower arc-shaped cooling plate along the first air-cooling pipe, and is blown out from the escape holes on the inner wall of the lower arc-shaped cooling plate to cool the fiber filaments.

In this way, air cooling and heat dissipation can be performed on various parts of the fiber filaments, which is beneficial to improving the cooling effect on the fiber filaments. At the same time, Part of the air flow enters the hollow air guide portion along the air guide pipe and flows out from the air outlet. In this process, the wind-driven impeller is driven to rotate by the air flow, and the water delivery auger in the first water guide pipe is driven to rotate synchronously under the joint action of the third transmission wheel, the fourth transmission wheel and the second transmission belt. Under the action of the water delivery auger, part of the water flow in the water cooling box is transported to the interior of the hollow water flow portion along the first water guide pipe and the second water guide pipe. The water flow entering the hollow water flow portion flows out along the drain pipe. The air flow pipe is cooled by the heat conduction effect of the water flow passing through the hollow water flow portion on the air flow pipe, thereby greatly improving the heat dissipation and cooling effect on the fiber filaments.

After oiling, the regenerated antibacterial and flame-retardant polyester DTY fiber is formed by winding. The oiling system is composed of a front oiler and a rear oiler.

[0038] A flow guide component 4 is provided between the oil storage tank 101 and the upper oil wheel group 3, and a passage-closing component 5 is rotatably provided on the flow guide component 4. The passage-closing component 5 is used to transport the oil in the oil storage tank 101 to the inner cavity of the upper oil wheel group 3. A buoyancy transmission component 6 is longitudinally slid on the buoyancy control box 102 and meshes with the passage-closing component 5 for transmission.

In this process, the water pressure plate 107 that moves downward synchronously with the support frame 109 squeezes the water in the hydraulic chamber 104, so that the water in the hydraulic chamber 104 gradually enters the buoyancy chamber 105 along the flow port 106, so that the water level in the buoyancy chamber 105 gradually rises, and then under the action of buoyancy, the buoyancy transmission assembly 6 moves upward to drive the opening and closing assembly 5 to rotate, thereby part of the oil in the oil storage tank 101 can be transported to the inner cavity of the upper oil wheel group 3 through the rotation of the opening and closing assembly 5. After the support frame 109 is controlled to move upward and reset by the hydraulic cylinder 108, the water pressure plate 107 returns to its initial position upward, and the upward-moving buoyancy transmission assembly 6 drives the opening and closing assembly 5 to rotate in the opposite direction, so that the opening and closing assembly 5 returns to its original state.

The transmission shaft 110 that rotates synchronously with the first gear 112 drives the first pulleys 111 thereon to rotate synchronously. In this process, the water pressure plate 107 that moves downward synchronously with the support frame 109 squeezes the water in the hydraulic chamber 104, so that the water in the hydraulic chamber 104 gradually enters the buoyancy chamber 105 along the flow port 106, so that The water level in the buoyancy chamber 105 gradually rises, and then under the action of buoyancy, the buoyancy ball 602 moves upward to drive the second gear 503 to rotate, thereby allowing part of the oil in the oil storage tank 101 to be transported to the inner cavity of the hollow upper oil wheel 301 through the rotation of the closure member 501 (that is, when the oil transfer chamber 502 rotates from the top to the bottom, the oil entering the oil transfer chamber 502 through the vertical guide pipe 403 is transported to the horizontal guide pipe 402, and then flows by gravity into the inner cavity of the hollow upper oil wheel 301 through the horizontal guide pipe 402 and is absorbed by the annular oil-absorbing cotton 12.

The air flow is transported to each air flow duct 903 along the main air duct 702 and each air inlet pipe 703 through the air supply equipment. Part of the air flow entering the air flow duct 903 enters the lower arc cooling plate 1002 along the first air cooling pipe 1001, and is blown out from the escape holes on the inner wall of the lower arc cooling plate 1002 to cool the fiber filaments. At the same time, part of the air flow in the air flow duct 903 enters the upper arc cooling plate 1101 along the second air cooling pipe 1103 and the hollow connecting seat 1102, and is blown out from the escape holes on the inner wall of the upper arc cooling plate 1101 to cool the fiber filaments. In this way, various parts of the fiber filaments can be cooled and dissipated, which is beneficial to improving the heat dissipation of the fiber filaments. The cooling effect is achieved, and at the same time, part of the air flow in the wind duct 903 enters the hollow wind guide part 707 along the air guide pipe 709 and flows out from the air outlet 708. In this process, the wind drive impeller is driven to rotate by the air flow, and the water delivery auger in the first water guide pipe 705 is driven to rotate synchronously under the joint action of the third transmission wheel 710, the fourth transmission wheel 711 and the second transmission belt 712. Under the action of the water delivery auger, part of the water flow in the water cooling box 704 is transported to the interior of the hollow water flow part 901 along the first water guide pipe 705 and the second water guide pipe 706. The water flow entering the hollow water flow part 901 flows out along the drain pipe 902, and the heat conduction effect of the water flow flowing through the hollow water flow part 901 on the wind duct 903 is realized. The wind duct 903 is cooled. This can greatly improve the heat dissipation and cooling effect on the fiber filaments.
