Description

Technical Field

[0001] This utility model relates to the field of hollow polyester staple fiber technology, and in particular to a pretreatment and impregnation device for hollow polyester staple fibers. Background Technology

[0002] Polyester (polyester fiber) is inherently hydrophobic, lacking polar groups in its molecular structure and exhibiting poor affinity for water or aqueous media. While its hollow structure increases specific surface area, it does not alter its hydrophobic nature. Pretreatment impregnation typically uses water or a solution containing surfactants. This impregnation causes the fiber surface to absorb moisture or auxiliaries, breaking down the hydrophobic state and creating conditions for subsequent processing (such as spinning, weaving, and nonwoven fabric production) to bond with other materials.

[0003] A search revealed a pretreatment device for hollow polyester staple fibers, application number 202421582667.2. The device includes a structural frame. A motor, mounted on a fixed plate, slides along a sliding groove under the operation of a hydraulic rod. The motor drives a bidirectional threaded rod, causing two flow shells to slide back and forth above a fine metal mesh, either facing each other or moving away from each other. Water is introduced into the flow shells via a pump and a delivery hose from a water tank and sprayed through an atomizing nozzle to moisten the material. As the flow shells slide, they cause brushes to slide against the fine metal mesh, preventing material adhesion and adhesion.

[0004] In existing technical solutions, water is introduced into the flow shell through a water tank via a pump and a delivery hose, and then sprayed out through an atomizing nozzle to wet the material. However, this method has the problem of insufficient wetting of hollow polyester staple fibers. Summary of the Invention

[0005] The purpose of this utility model is to provide a pretreatment and wetting device for hollow polyester staple fibers, wherein the vibration draining component (5) and the vibration cleaning component (7) work together to vibrate, thereby enabling the hollow polyester staple fibers (2) to be fully vibrated and wetting in the water in the wetting tank (1), so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pretreatment impregnation device for hollow polyester staple fibers, comprising an impregnation tank, an impregnation pressure roller rotatably mounted inside the impregnation tank, hollow polyester staple fibers adhering to the lower end face of the impregnation pressure roller being disposed inside the impregnation tank, and a first transmission roller rotatably mounted at the rear of the upper end of the impregnation tank.

[0007] An immersion drive assembly is provided at the middle of the upper end of the immersion tank. A vibration drain assembly and a vibration cleaning assembly are respectively provided at the output end of the immersion drive assembly. A cleaning collection box is fixedly installed at the front end of the immersion tank. A cleaning auxiliary assembly is provided at the upper end of the cleaning collection box. A second transmission roller is rotatably installed at the front of the upper end of the cleaning collection box.

[0008] Preferably, the immersion drive assembly includes a first support frame fixedly installed at the middle position of the upper end of the immersion tank, and a drive motor is fixedly installed on the side wall of the first support frame.

[0009] Preferably, the output end of the drive motor is fixedly connected to a drive shaft through the inner wall of the first support frame, and multiple drive helical gears are fixedly installed at equal intervals on the shaft wall of the drive shaft.

[0010] Preferably, the vibratory drain assembly includes a second support frame fixed to the upper surface of the soaking tank, a first shaft frame fixedly installed at the bottom end of the second support frame, and a first drive shaft rotatably installed inside the first shaft frame.

[0011] Preferably, a first transmission helical gear is fixedly connected to the power input end of the first transmission shaft, a first transmission sleeve is fixedly connected to the power output end of the first transmission shaft, and first paddles with equal angle distribution are fixedly installed on the outer wall of the first transmission sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The vibration drainage component and the vibration cleaning component of this utility model work together to vibrate, thereby enabling the hollow polyester staple fibers to be fully vibrated and wetted in the water in the immersion tank. This ensures the overall wettability of the hollow polyester staple fibers. For hollow polyester staple fibers, this elasticity can also promote the uniform distribution of the wetting liquid in the hollow cavities and on the surface of the fibers, ensuring that each bundle and each fiber can fully interact with the wetting liquid and improve the consistency of overall wettability.

[0017] 2. The driving helical gear in this invention simultaneously drives the first transmission helical gear and the second transmission helical gear to rotate, enabling the vibration cleaning component to operate in conjunction with the vibration draining component after immersion. This eliminates the need for an additional power source, simplifies the device structure, and reduces energy consumption. This linkage design ensures seamless connection between the three key stages of cleaning, immersion, and draining, reducing waiting time between processes and improving the overall efficiency of pretreatment.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A pretreatment impregnation device for hollow polyester staple fibers includes an impregnation tank 1, an impregnation pressure roller 3 rotatably mounted inside the impregnation tank 1, hollow polyester staple fibers 2 adhering to the lower end face of the impregnation pressure roller 3 inside the impregnation tank 1, a first drive roller 6 rotatably mounted at the upper rear of the impregnation tank 1, an impregnation drive assembly 4 disposed at the middle position of the upper end of the impregnation tank 1, a vibration draining assembly 5 and a vibration cleaning assembly 7 respectively disposed at the output end of the impregnation drive assembly 4, a cleaning collection box 9 fixedly mounted at the front end of the impregnation tank 1, a cleaning auxiliary assembly 8 disposed at the upper end of the cleaning collection box 9, and a second drive roller 10 rotatably mounted at the front of the upper end of the cleaning collection box 9.

[0028] The immersion drive assembly 4 includes a first support frame 401 fixedly installed at the middle position of the upper end of the immersion tank 1. A drive motor 402 is fixedly installed on the side wall of the first support frame 401. The output end of the drive motor 402 is fixedly connected to a transmission shaft 403 through the inner wall of the first support frame 401. Multiple drive helical gears 404 are fixedly installed at equal intervals on the shaft wall of the transmission shaft 403.

[0029] The vibration cleaning assembly 7 includes a third support frame 701 fixedly installed on the upper surface of the immersion tank 1. A second shaft frame 702 is fixedly installed on the lower surface of the third support frame 701. A second transmission shaft 703 is rotatably installed inside the second shaft frame 702. A second transmission helical gear 706 is fixedly connected to the power input end of the second transmission shaft 703. A second transmission sleeve 704 is fixedly connected to the power output end of the second transmission shaft 703. Second paddles 705 distributed at equal angles are fixedly installed on the outer wall of the second transmission sleeve 704. The cleaning auxiliary assembly 8 includes a sleeve 801 fixedly installed at the middle position of the upper end of the cleaning collection box 9. Springs 802 are fixedly installed on both sides of the bottom end of the sleeve 801. A cleaning brush 803 is fixedly installed inside the hollow interior of the sleeve 801.

[0030] By adopting the above technical solution, when pre-treating and impregnating the hollow polyester staple fiber 2, the hollow polyester staple fiber 2 is threaded into a suitable position inside the device. During the impregnation process, the second transmission roller 10 and the first transmission roller 6 can drive the hollow polyester staple fiber 2 by rotation. The impregnation pressure roller 3 presses the pulled hollow polyester staple fiber 2 below the water surface inside the impregnation tank 1. At the same time, the drive motor 402 is started. The drive motor 402 drives the transmission shaft 403 to rotate. The rotation of the transmission shaft 403 drives the drive helical gear 404 to rotate. The rotation of the gear drives the meshing second transmission helical gear 706 to rotate, which in turn drives the second transmission shaft 703 to rotate on the second shaft bracket 702. The rotation of the second transmission shaft 703 drives the second transmission sleeve 704 and the second paddle 705 to rotate, thereby causing the arc-shaped inclined surface at the top of the second paddle 705 to move the corresponding hollow polyester staple fiber 2. When the hollow polyester staple fiber 2 moves to a certain position, it slides off the arc-shaped inclined surface at the top of the second paddle 705, causing it to bounce. This allows the hollow polyester staple fiber 2 to... Dust and other debris fall into the corresponding cleaning collection box 9. The second paddle 705, through its curved inclined surface, flicks and bounces the hollow polyester staple fibers 2. Utilizing the vibration of the fibers themselves, it efficiently shakes off dust and impurities adhering to the surface, causing them to fall into the cleaning collection box 9, reducing contaminants on the fiber surface. Simultaneously, the movement of multiple bundles of hollow polyester staple fibers 2 causes the sleeve 801 to elastically vibrate at the upper end of the cleaning collection box 9 via the spring 802, further improving the dust cleaning effect. The sleeve 801, under the action of the spring 802, generates elastic vibration with the fiber movement, further enhancing the amplitude and frequency of fiber vibration, allowing... Impurities hidden in fiber gaps or difficult to remove are more easily removed. Furthermore, the movement of the hollow polyester staple fiber 2 within the holder 801 allows for further cleaning of its surface by the cleaning brush 803. This ensures the cleanliness of the hollow polyester staple fiber 2 before impregnation. The cleaning brush 803 directly contacts the moving fiber surface, providing comprehensive wiping and removing fine dust or sticky impurities that did not dislodge during the bouncing process. This ensures the fiber achieves a high degree of cleanliness before entering the impregnation stage, laying a good foundation for subsequent processing and preventing impurities from affecting the quality of the final product. After thorough cleaning, the hollow polyester staple fiber 2 has no impurities obstructing its surface, allowing for faster and more even contact with the impregnation liquid during impregnation. This enables the fiber to fully absorb the impregnation liquid, shortening the impregnation time and improving pretreatment efficiency.

[0031] Specifically, such as Figures 1-2As shown, the vibrating drainage assembly 5 includes a second support frame 501 fixed to the upper surface of the soaking tank 1. A first shaft frame 502 is fixedly installed at the bottom end of the second support frame 501. A first transmission shaft 503 is rotatably installed inside the first shaft frame 502. A first transmission helical gear 506 is fixedly connected to the power input end of the first transmission shaft 503. A first transmission sleeve 504 is fixedly connected to the power output end of the first transmission shaft 503. First paddles 505 with equal angle distribution are fixedly installed on the outer wall of the first transmission sleeve 504.

[0032] By adopting the above technical solution, when the driving helical gear 404 rotates, it can simultaneously drive the meshing first transmission helical gear 506 to rotate. The rotation of the first transmission helical gear 506 can drive the first transmission shaft 503 to rotate on the first shaft bracket 502. The rotation of the first transmission shaft 503 can drive the first transmission sleeve 504 and the first paddle 505 to rotate, thereby enabling the arc-shaped inclined surface at the top of the first paddle 505 to move the corresponding wetted hollow polyester staple fiber 2. When the hollow polyester staple fiber 2 moves to a certain position, the hollow polyester staple fiber 2 slides down through the arc-shaped inclined surface at the top of the first paddle 505, thereby causing the hollow polyester staple fiber 2 to bounce. The elasticity of the short fibers 2 allows excess water to be shaken off after impregnation, ensuring uniform water penetration. During impregnation, the coordinated vibration of the vibrating draining component 5 and the vibrating cleaning component 7 ensures thorough wetting of the fibers in the impregnation tank 1, guaranteeing overall impregnation. For hollow polyester short fibers, this elasticity also promotes uniform distribution of the impregnation solution within the hollow cavities and on the surface of the fiber, ensuring each bundle and each fiber interacts fully with the solution and improving overall impregnation consistency. The coordinated vibration of the vibrating draining component 5 and the vibrating cleaning component 7 keeps the fibers in a dynamic state within the impregnation tank 1, preventing insufficient localized impregnation caused by gravity or entanglement when the fibers are stationary. Dynamic vibration allows the impregnation solution to penetrate the gaps and hollow parts of the fibers more efficiently, especially for short fibers, reducing impregnation blind spots caused by mutual shading between fibers. The driving helical gear 404 simultaneously drives the first transmission helical gear 506 and the second transmission helical gear 706 to rotate, creating a linkage between the vibration cleaning component 7 (before impregnation) and the vibration draining component 5 (after impregnation). This eliminates the need for an additional power source, simplifying the device structure and reducing energy consumption. This linkage design seamlessly connects the three key stages of cleaning, impregnation, and draining, reducing waiting time between processes and improving the overall efficiency of pretreatment.

[0033] Working principle: During use, when pre-treating and impregnating the hollow polyester staple fiber 2, the hollow polyester staple fiber 2 is threaded into a suitable position inside the device. During the impregnation process, the second transmission roller 10 and the first transmission roller 6 drive the hollow polyester staple fiber 2 through rotation. The impregnation pressure roller 3 presses the pulled hollow polyester staple fiber 2 below the water surface inside the impregnation tank 1. At the same time, the drive motor 402 is started. The drive motor 402 drives the transmission shaft 403 to rotate. The rotation of the transmission shaft 403 drives the drive helical gear 404 to rotate. The rotation of the drive helical gear 404 drives the meshed second transmission helical gear 706 to rotate. The rotation of gear 706 drives the second transmission shaft 703 to rotate on the second shaft bracket 702. The rotation of the second transmission shaft 703 drives the second transmission sleeve 704 and the second paddle 705 to rotate, thereby causing the arc-shaped inclined surface at the top of the second paddle 705 to move the corresponding hollow polyester staple fiber 2. When the hollow polyester staple fiber 2 moves to a certain position, it slides off the arc-shaped inclined surface at the top of the second paddle 705, causing it to bounce. This allows dust and other debris on the hollow polyester staple fiber 2 to fall into the corresponding cleaning collection box 9. At the same time, the movement of multiple bundles of hollow polyester staple fibers 2 causes the sleeve 801 to rotate via spring 802. The upper end of the cleaning collection box 9 vibrates elastically, thereby further improving the dust cleaning effect. Furthermore, the movement of the hollow polyester staple fiber 2 within the sleeve 801 allows the cleaning brush 803 to further clean the surface of the hollow polyester staple fiber 2. When the drive helical gear 404 rotates, it simultaneously drives the meshing first transmission helical gear 506 to rotate. The rotation of the first transmission helical gear 506 drives the first transmission shaft 503 to rotate on the first shaft bracket 502. The rotation of the first transmission shaft 503 drives the first transmission sleeve 504 and the first paddle 505 to rotate, thereby causing the arc-shaped inclined surface at the top of the first paddle 505 to pick up the corresponding wetted hollow polyester staple fiber. The hollow polyester staple fiber 2 moves, and when it reaches a certain position, it slides down the arc-shaped inclined surface at the top of the first deflector 505, causing it to bounce. This bounce helps to remove excess water from the hollow polyester staple fiber 2 after immersion, ensuring uniform water immersion. During immersion, the vibration and drainage assembly 5 and the vibration and cleaning assembly 7 work together to ensure the hollow polyester staple fiber 2 receives sufficient vibration and immersion treatment in the immersion tank 1, thus guaranteeing the overall immersion effect.
