Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric disinfection technology, specifically a fireproof and flame-retardant nonwoven fabric ultraviolet disinfection preparation machine. Background Technology

[0002] Fire-retardant nonwoven fabrics play a crucial role in numerous fields, including medical, industrial, and daily life. These fabrics are specially treated to possess fire-retardant properties, effectively preventing the spread of fire and reducing damage from fires. Furthermore, in applications with extremely high hygiene requirements, such as medical supply manufacturing and food processing, nonwoven fabrics undergo rigorous disinfection to kill any potential bacteria and viruses, ensuring safe use. Therefore, nonwoven fabrics that combine fire resistance, flame retardancy, and hygiene have become a pressing market demand.

[0003] However, traditional nonwoven fabric processing technologies have significant shortcomings. In terms of disinfection, some traditional methods are limited in effectiveness, failing to completely eliminate various microorganisms on the nonwoven fabric, resulting in lingering hygiene risks even after disinfection. Furthermore, traditional technologies often treat fire-retardant treatment and disinfection as two separate processes. This separate approach not only increases production costs and time but may also lead to secondary contamination of the nonwoven fabric during processing, affecting the quality and performance of the final product. In addition, traditional processing equipment lacks automation and precision, making it difficult to ensure consistent treatment results for each batch of nonwoven fabric, failing to meet the demands of large-scale, high-quality production, and severely restricting the widespread application of fire-retardant nonwoven fabrics in related fields. Therefore, we propose a UV disinfection preparation machine for fire-retardant nonwoven fabrics. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a fire-retardant and flame-retardant nonwoven fabric ultraviolet disinfection preparation machine, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a fire-retardant and flame-retardant nonwoven fabric ultraviolet disinfection preparation machine, comprising a fixed base, a working box provided at the bottom of the inner wall of the fixed base, the top of the working box extending to the top of the fixed base, a fixed frame fixedly connected to one end of the inner wall of the working box, an adjusting ring movably connected to the inner wall of the fixed frame, movable sleeves movably connected to both ends of the inner wall of the adjusting ring, a second movable sleeve movably connected to the inner wall of the adjusting ring near the movable sleeve, the second movable sleeve and the ultraviolet disinfection plate being distributed in a ring at equal intervals, an adjusting arm movably connected to the outer wall of one end of the fixed frame, and one end of the adjusting arm movably sleeved onto one end of the inner wall of the movable sleeve.

[0006] Preferably, an ultraviolet disinfection plate is movably connected to the end of the adjusting arm away from the fixed frame.

[0007] Preferably, a second adjusting arm is movably connected to the outer wall of the fixed frame near the adjusting arm, and the outer wall of the second adjusting arm is movably sleeved on the inner wall of the second movable sleeve. A second ultraviolet disinfection plate is movably connected to the end of the second adjusting arm away from the fixed frame.

[0008] Preferably, the second ultraviolet disinfection plate is located directly below the ultraviolet disinfection plate, and the output direction of the second ultraviolet disinfection plate is opposite to that of the ultraviolet disinfection plate.

[0009] Preferably, a gear ring is sleeved on the outer wall of the adjusting ring, and a forward and reverse motor is fixedly connected to the outer wall of the fixed frame near the adjusting arm. A gear is fixedly connected to the rotating shaft of the forward and reverse motor, and the gear and the gear ring are meshed.

[0010] Preferably, an infeed roller is movably connected to the outer wall of one end of the fixed base, a take-up roller is movably connected to the outer wall of the fixed base away from the infeed roller, a servo motor is fixedly connected to the outer wall of the fixed base near the take-up roller, and the rotation shaft of the servo motor is fixedly connected to a connecting shaft on one side of the take-up roller.

[0011] Preferably, the in-wind roller and the take-up roller are parallel to the output direction of the fixed frame.

[0012] Compared with the prior art, this utility model provides a fireproof and flame-retardant non-woven fabric ultraviolet disinfection preparation machine, which has the following beneficial effects:

[0013] 1. This fire-retardant and flame-retardant nonwoven fabric ultraviolet disinfection preparation machine addresses the shortcomings of traditional nonwoven fabric disinfection technologies, which often suffer from incomplete disinfection and low efficiency. Traditional methods often fail to completely eliminate various microorganisms on nonwoven fabrics, and the disinfection process can be cumbersome, impacting production efficiency. This fire-retardant and flame-retardant nonwoven fabric ultraviolet disinfection preparation machine utilizes a unique dual ultraviolet disinfection plate design: an upper ultraviolet disinfection plate and a lower second ultraviolet disinfection plate with opposite output directions. The nonwoven fabric receives ultraviolet irradiation from both directions simultaneously as it passes through. This comprehensive disinfection method significantly improves efficiency, ensuring the complete elimination of bacteria and viruses on the nonwoven fabric. Compared to traditional technologies, this device not only shortens disinfection time but also significantly improves disinfection effectiveness, providing a more reliable guarantee for the application of nonwoven fabrics in medical and hygiene fields with extremely high hygiene requirements, and effectively reducing the risk of cross-infection due to incomplete disinfection.

[0014] 2. This fire-retardant nonwoven fabric ultraviolet disinfection preparation machine differs from traditional nonwoven fabric treatment equipment. Traditional equipment typically uses a fixed spacing between ultraviolet disinfection plates, making it difficult to adjust flexibly to accommodate different specifications and thicknesses of nonwoven fabric, resulting in inconsistent disinfection effects. This machine utilizes a combination of forward and reverse motors, gears, and a gear ring to drive an adjusting ring, enabling precise adjustment of the second and third ultraviolet disinfection plates. This flexible adjustment function allows the device to adapt to nonwoven fabrics of varying widths, thicknesses, and materials, ensuring that ultraviolet light fully irradiates all parts of the fabric, guaranteeing uniform and comprehensive disinfection. Compared to traditional technologies, this device significantly improves production adaptability and flexibility, meeting diverse customer needs, reducing production problems caused by equipment incompatibility with nonwoven fabric specifications, and improving production efficiency and product quality.

[0015] 3. This fire-retardant nonwoven fabric ultraviolet disinfection preparation machine addresses the traditional nonwoven fabric disinfection process, where the fabric conveying often relies on manual operation. This is not only labor-intensive but also prone to problems such as unstable conveying and inconsistent speeds, affecting disinfection effectiveness and production efficiency. This machine achieves automated nonwoven fabric conveying through the cooperation of the infeed and take-up rollers and the precise control of a servo motor. The servo motor provides stable power to the take-up roller, ensuring the nonwoven fabric passes through the disinfection area at a constant speed, guaranteeing that each section of nonwoven fabric receives the same intensity of ultraviolet irradiation, thus ensuring consistent disinfection results. Compared to traditional technologies, the automated conveying and precise control functions of this device reduce manual intervention, lower labor intensity, and improve production stability and reliability. Simultaneously, the automated production method increases production efficiency, meeting the needs of large-scale production, reducing production costs for enterprises, and improving economic benefits.

A working box 2 is provided at the bottom of the inner wall of the fixed base 1, and the top of the working box 2 extends to the top of the fixed base 1, providing a relatively closed and stable working environment for the entire disinfection preparation process, reducing external interference and ensuring the smooth progress of disinfection. A fixed frame 3 is fixedly connected to one end of the inner wall of the working box 2. The fixed frame 3 provides support for the adjusting ring 4. The adjusting ring 4 can be movably connected to facilitate subsequent adjustment of the spacing of the ultraviolet disinfection plates to adapt to different production needs. The adjusting ring 4 is movably connected to the inner wall of the fixed frame 3. Movable sleeves 5 are movably connected to both ends of the inner wall of the adjusting ring 4. A second movable sleeve 8 is movably connected to the inner wall of the adjusting ring 4 near the movable sleeve 5. The second movable sleeve 8 and the ultraviolet disinfection plates 7 are distributed in a ring at equal intervals. The arrangement of the movable sleeves 5 and the second movable sleeve 8 allows the ultraviolet disinfection plates 7 to flexibly adjust the spacing. The ring at equal intervals ensures the uniformity of ultraviolet irradiation. An adjusting arm 6 is movably connected to the outer wall of one end of the fixed frame 3. The outer wall of the adjusting arm 6 is movably sleeved on one end of the inner wall of the movable sleeve 5.

[0023] Furthermore, an ultraviolet disinfection plate 7 is movably connected to the end of the adjusting arm 6 away from the fixed frame 3. The adjusting arm 6 can drive the ultraviolet disinfection plate 7 to adjust the spacing, so that the ultraviolet rays can accurately and comprehensively irradiate the non-woven fabric, thereby improving the disinfection effect.

[0024] Furthermore, a second adjusting arm 9 is movably connected to the outer wall of the fixed frame 3 near the adjusting arm 6. The outer wall of the second adjusting arm 9 is movably sleeved on the inner wall of the second movable sleeve 8.

The cooperation between the second adjusting arm 9 and the second movable sleeve 8 allows the second ultraviolet disinfection plate 10 to be flexibly adjusted and work in conjunction with the ultraviolet disinfection plate 7 to enhance the disinfection capability.

[0025] Furthermore, the second ultraviolet disinfection plate 10 is located directly below the ultraviolet disinfection plate 7. The output directions of the second ultraviolet disinfection plate 10 and the ultraviolet disinfection plate 7 are opposite. This top-to-bottom arrangement allows the non-woven fabric to receive ultraviolet irradiation from both top and bottom directions simultaneously when it passes through, greatly improving the efficiency and comprehensiveness of disinfection.

[0026] Furthermore, a gear ring 11 is sleeved on the outer wall of the adjusting ring 4, and a forward and reverse motor 12 is fixedly connected to the outer wall of the fixed frame 3 near the adjusting arm 6. A gear 13 is fixedly connected to the rotating shaft of the forward and reverse motor 12. The gear 13 and the gear ring 11 are meshed. The forward and reverse motor 12 drives the adjusting ring 4 to rotate through the meshing transmission of the gear 13 and the gear ring 11, thereby realizing the precise adjustment of the ultraviolet disinfection plate 7 and the second ultraviolet disinfection plate 10, and meeting the disinfection needs of non-woven fabrics of different specifications.

[0027] Furthermore, an infeed roller 14 is movably connected to the outer wall of one end of the fixed base 1, and a take-up roller 15 is movably connected to the outer wall of the fixed base 1 away from the infeed roller 14. A servo motor 16 is fixedly connected to the outer wall of the fixed base 1 near the take-up roller 15. The rotation shaft of the servo motor 16 is fixedly connected to a connecting shaft on one side of the take-up roller 15. The infeed roller 14 and the take-up roller 15 cooperate with each other to realize the automatic feeding of nonwoven fabric. The servo motor 16 provides power to the take-up roller 15 to ensure that the nonwoven fabric passes through the disinfection area at a stable speed and ensures the consistency of the disinfection effect.

[0028] Furthermore, the in-wind roller 14 and the take-up roller 15 are parallel to the output direction of the fixed frame 3 to ensure that the nonwoven fabric remains stable during the conveying process, avoid wrinkles or deviations in the nonwoven fabric due to inconsistent directions, and ensure that ultraviolet rays can irradiate the nonwoven fabric evenly, thereby improving the disinfection quality.

[0047] Working Principle: The nonwoven fabric first enters the entire process through the infeed roller 14. The infeed roller 14 and take-up roller 15 are parallel to the output direction of the fixed frame 3, providing a foundation for the smooth transport of the nonwoven fabric. The servo motor 16 starts, and its rotating shaft drives the take-up roller 15 to rotate. The rotation of the take-up roller 15 generates tension, causing the nonwoven fabric to be pulled out from the infeed roller 14 and move towards the interior of the working box 2 along the output direction of the fixed frame 3. Inside the working box 2, the fixed frame 3 plays a crucial supporting and connecting role. An adjusting arm 6 is movably connected to the outer wall of one end of the fixed frame 3.

The design of the adjusting ring 4 makes it possible to adjust the distance between the ultraviolet disinfection plate 7 and the second ultraviolet disinfection plate 10. Movable sleeves 5 are movably connected to both ends of the inner wall of the adjusting ring 4. A second movable sleeve 8 is movably connected to the inner wall of the adjusting ring 4 near the movable sleeve 5. The second movable sleeve 8 and the ultraviolet disinfection plate 7 are distributed in a ring at equal intervals. One end of the adjusting arm 6 is movably sleeved on the outer wall of the movable sleeve 5, and one end of the second adjusting arm 9 is movably sleeved on the outer wall of the second movable sleeve 8.
