Description

Technical Field

[0001] This application relates to the technical field of nonwoven fabric production, and in particular to an apparatus for scenting nonwoven fabrics. Background Technology

[0002] Nonwoven fabrics are a versatile material used in various fields such as hygiene products, home décor, and packaging. By adding fragrance, nonwoven fabrics can not only emit pleasant scents but also enhance product added value and market competitiveness. Common fragrance-adding processes for nonwoven fabrics mainly include soaking, roller coating, and spraying.

[0003] In the fragrance addition process of nonwoven fabrics, the spray method is widely used due to its simplicity and low cost. In actual production, an appropriate amount of fragrance raw materials are first mixed in a specific ratio to make a fragrance. Then, the fragrance is put into a container with a nozzle, and the fragrance is converted into fine droplets by pressure and sprayed onto the surface of the nonwoven fabric.

[0004] Regarding the aforementioned technologies, the spray from the spray device is difficult to adhere evenly to the surface of the non-woven fabric, resulting in differences in fragrance concentration in some areas of the non-woven fabric. Furthermore, the fine spray particles may drift in the air and fail to adhere to the surface of the non-woven fabric, causing fragrance waste. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a device for adding fragrance to non-woven fabrics.

[0006] This application provides a device for scenting nonwoven fabrics, which adopts the following technical solution: A device for scenting nonwoven fabrics includes a housing, a spraying device, a conveying device, and a fan. The spraying device is installed on the outside of the housing and has a nozzle that extends into the interior of the housing. The inner wall of the housing has an inlet and an outlet, with the outlet located on the inner wall opposite the inlet. The fan is installed on the inner wall of the housing, located on the left and right sides of the inlet and outlet. The conveying device is installed inside the housing.

[0007] By adopting the above technical solution, the conveying device ensures that every area of ​​the nonwoven fabric is fully in contact with the evenly diffused mist fragrance during the movement of the conveyor, avoiding fragrance differences caused by uneven residence time or dead air zones. The fan layout utilizes the relative positions of the inlet and outlet to create air convection, which not only accelerates the diffusion speed of the mist fragrance but also makes the fragrance molecules more evenly adsorbed on the surface of the nonwoven fabric through the dynamic balance of airflow. Moreover, the device can achieve a highly efficient and uniform fragrance effect through the synergistic action of mechanical components, reducing equipment costs and maintenance difficulties, while meeting the dual requirements of fragrance adhesion uniformity and production efficiency in nonwoven fabric production.

[0008] Preferably, the conveying device includes an upper conveying roller and a lower conveying roller, which are installed horizontally. The axial directions of the upper and lower conveying rollers are perpendicular to the conveying direction of the nonwoven fabric. The upper conveying roller is installed in the top area of ​​the inner wall of the box, and its axis is higher than the nozzle. The lower conveying roller is installed in the bottom area of ​​the inner wall of the box, and its axis is lower than the nozzle.

[0009] By adopting the above technical solution, the height difference design causes the non-woven fabric to frequently change direction during the conveying process, thereby increasing the actual running path length of the non-woven fabric in the box and the contact area with the mist fragrance. This avoids sagging or wrinkling of the non-woven fabric due to gravity during horizontal conveying, providing a flat surface for uniform fragrance adhesion. At the same time, the upper and lower conveying rollers allow the non-woven fabric to pass through the fragrance application area in a stable posture, enabling the mist fragrance to be evenly adsorbed on the surface of the non-woven fabric. This design achieves all-round, dead-angle-free, and uniform adhesion of fragrance during the movement of the non-woven fabric, improving the fragrance application quality while ensuring the stability and continuity of the production process.

[0010] Preferably, there are multiple upper and lower conveying rollers, with adjacent upper conveying rollers having a horizontal distance between them, and the horizontal distance between adjacent lower conveying rollers being the same as the horizontal distance between the upper conveying rollers. The upper and lower conveying rollers are horizontally staggered, meaning that the lower conveying rollers are located between two upper conveying rollers.

[0011] By adopting the above technical solution, the horizontal spacing between adjacent rollers is consistent and their staggered layout creates a wavy conveying trajectory for the nonwoven fabric. This avoids substrate sagging or central loosening caused by a large span of a single roller, ensuring that the surface can accept the adhesion of the mist fragrance. Simultaneously, the alternating distribution of the upper and lower conveying rollers provides stable adhesion conditions for uniform fragrance application. This allows the mist fragrance to quickly diffuse within the gap between the upper and lower rollers, penetrating both sides of the nonwoven fabric.

[0012] Preferably, the inlet and outlet are provided with shielding curtains, which are fixed to the inner sides of the inlet and outlet and are evenly arranged along the circumference of the opening, with their length consistent with the width of the nonwoven fabric.

[0013] By adopting the above technical solution, the shielding curtains at the inlet and outlet can directly contact the nonwoven fabric when it enters and leaves, smoothing the surface of the nonwoven fabric and eliminating wrinkles that may be caused by external contact, fan airflow or roller contact. At the same time, it prevents the leakage of fragrance droplets that are not fully attached inside the box, keeping the production environment clean. The circumferentially uniform distribution design of the shielding curtain allows it to fit the width direction of the nonwoven fabric, contacting the edges and center of the nonwoven fabric without dead angles, ensuring that the nonwoven fabric can enter the box in a stable posture.

[0014] Preferably, the blind curtain is made of nylon.

[0015] By adopting the above technical solutions, the high strength and wear-resistant properties of the nylon curtain make it less prone to wear or breakage when in long-term contact with the edges and surfaces of the non-woven fabric. This ensures the long-lasting and stable cleaning and combing function of the inlet and outlet, preventing contamination or equipment malfunction caused by curtain detachment. Furthermore, its soft texture effectively removes dust and other impurities from the non-woven fabric surface without damaging it, providing an excellent carrier for even fragrance application. Simultaneously, the chemical resistance of nylon resists the erosion of alcohol, surfactants, and other components that may be present in the fragrance solution, preventing the curtain from hardening, deforming, or developing odors due to prolonged contact with chemicals, ensuring it maintains excellent flexible contact performance.

[0016] Preferably, the top of the box is provided with a spray pipe, the end of the spray pipe is provided with a spray head with the spray end facing downward, the tail end of the spray pipe passes through the box and is connected to an external spraying device, and a water receiving tray is installed at the bottom of the box, the water receiving tray covering the bottom of the box.

[0017] By adopting the above technical solution, the combined use of the spray pipes and the water tray allows the interior of the chamber to be cleaned and maintained after long-term operation. The full-coverage design of the water tray fits tightly into the chamber structure, eliminating cleaning dead corners and ensuring no wastewater residue after rinsing. The downward spray angle of the spray pipes effectively eliminates odor problems caused by fragrance residue. From an equipment maintenance perspective, this ensures the stability of the fragrance application process and the quality and safety of the non-woven fabric product, while also improving the automated cleaning capability of the device.

[0018] Preferably, the water receiving tray is funnel-shaped and has a drain outlet at the lowest point of the water receiving tray.

[0019] By adopting the above technical solution, the funnel-shaped layout allows the wastewater generated by spray cleaning to naturally converge to the drain outlet at the lowest point of the water receiving tray by gravity, avoiding problems such as bacterial growth, equipment corrosion, or odor residue caused by flat water accumulation.

[0020] Preferably, a removable water tank is provided below the drain outlet.

[0021] By adopting the above technical solution, the detachable structure allows the water tank to be easily removed, facilitating the regular emptying of the spray wastewater and any impurities that may be mixed in, preventing the waste liquid from stagnating for a long time and generating odors or polluting the environment. At the same time, the inclined diversion design of the water tank and the water tray complements each other, improving the cleaning and maintenance chain of the equipment, simplifying the manual operation process, and ensuring the environmental friendliness of the fragrance addition process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying device ensures that every area of ​​the nonwoven fabric is fully in contact with the evenly diffused mist fragrance during the movement of the conveyor, avoiding fragrance differences caused by uneven residence time or dead air zones. The fan layout utilizes the relative positions of the inlet and outlet to create air convection, which not only accelerates the diffusion speed of the mist fragrance but also makes the fragrance molecules more evenly adsorbed on the surface of the nonwoven fabric through the dynamic balance of airflow. Moreover, this device can achieve a highly efficient and uniform fragrance effect through the synergistic action of mechanical components, reducing equipment costs and maintenance difficulties, while meeting the dual requirements of fragrance adhesion uniformity and production efficiency in nonwoven fabric production. 2. The height difference design of the conveying device causes the non-woven fabric to frequently change direction during the conveying process, thereby increasing the actual running path length of the non-woven fabric in the box and the contact area with the mist fragrance. This avoids the sagging or wrinkling of the non-woven fabric due to gravity when it is conveyed horizontally, and provides a flat surface for the uniform adhesion of the fragrance. At the same time, the upper and lower conveying rollers allow the non-woven fabric to pass through the fragrance application area in a stable posture, so that the mist fragrance can be evenly absorbed on the surface of the non-woven fabric. This design achieves all-round, dead-angle-free uniform adhesion of the fragrance during the movement of the non-woven fabric, improving the fragrance application quality while ensuring the stability and continuity of the production process. 3. The consistent horizontal spacing and staggered arrangement of adjacent rollers create a wavy conveying trajectory for the nonwoven fabric, preventing substrate sagging or central loosening caused by large spans of a single roller, thus ensuring the surface can accept the adhesion of the mist fragrance. Simultaneously, the alternating distribution of the upper and lower conveying rollers provides stable adhesion conditions for uniform fragrance application. This allows the mist fragrance to quickly diffuse within the gaps between the upper and lower rollers, penetrating both sides of the nonwoven fabric. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0026] This application discloses an apparatus for scenting nonwoven fabrics.

[0027] Reference Figure 1 and Figure 2 A device for scenting non-woven fabric includes a housing 1, a spraying device 2, a conveying device 3, and two fans 4. The spraying device 2 is installed on the outside of the housing 1, and the spraying device 2 has nozzles 5 that extend into the interior of the housing 1. The inner wall of the housing 1 has an inlet 6 and an outlet 7, with the outlet 7 located on the inner wall opposite to the inlet 6. The two fans 4 are installed on the inner wall of the housing 1, located on the left and right sides of the inlet 6 and outlet 7. The conveying device 3 is installed inside the housing 1. Non-woven fabric 00 enters through the inlet 6, is transported by the conveying device 3, and exits through the outlet 7. When non-woven fabric 00 enters the housing 1, the nozzles 5 spray the fragrance from the spraying device 2. At the same time, the fans 4 start and disperse the mist fragrance, allowing it to adhere to the non-woven fabric 00. The fans 4 disperse the mist fragrance to avoid localized concentrations of fragrance on the non-woven fabric 00, ensuring that the mist fragrance adheres more evenly to the surface of the non-woven fabric 00.

[0028] The inlet 6 and outlet 7 are equipped with shielding curtains 8, which are fixed to the inner sides of the inlet 6 and outlet 7 and are evenly arranged along the circumference of the opening. The length of the shielding curtains is consistent with the width of the non-woven fabric 00. Preferably, the shielding curtains 8 are made of nylon. When the non-woven fabric 00 enters the box 1 from the inlet 6, the shielding curtains 8 can prevent the incompletely attached mist fragrance from escaping from the box 1 with the airflow, thereby reducing the outward diffusion of fragrance inside the box 1 and the waste of fragrance. The flexible material of the shielding curtains 8 avoids rigid contact between the inlet 6 and outlet 7 and the non-woven fabric 00, preventing damage to the surface of the non-woven fabric 00 and further protecting the quality of the non-woven fabric 00.

[0029] The conveying device 3 includes multiple conveying rollers, all of which are installed horizontally with their axes perpendicular to the conveying direction of the nonwoven fabric 00, ensuring that the nonwoven fabric 00 moves smoothly under the friction of the roller surfaces during conveying. Further, the multiple conveying rollers are divided into upper conveying rollers 301 and lower conveying rollers 302. The upper conveying rollers 301 are installed in the top area of ​​the inner wall of the housing 1, with their axes higher than the nozzle 5, and adjacent upper conveying rollers 301 are spaced a certain distance apart in the horizontal direction. The lower conveying rollers 302 are installed in the bottom area of ​​the inner wall of the housing 1, with their axes lower than the nozzle 5. The horizontal distance between adjacent lower conveying rollers 302 is the same as the horizontal distance between upper conveying rollers 301, but the horizontal positions of the upper conveying rollers 301 and lower conveying rollers 302 are staggered, i.e., the lower conveying rollers 302 are located between the two upper conveying rollers 301.

[0030] By setting multiple conveying rollers, and staggering the positions of the upper conveying roller 301 and the lower conveying roller 302, the nonwoven fabric 00 frequently changes direction during the conveying process, thereby increasing the actual running path length of the nonwoven fabric 00 in the box 1 and the contact area with the mist fragrance, effectively improving the efficiency of fragrance adhering to the nonwoven fabric 00.

[0031] The top of the box body 1 is provided with a spray pipe 9, and the end of the spray pipe 9 is provided with several spray heads 10 with the spray end facing downward. The tail end of the spray pipe 9 passes through the box body 1 and is connected to the external spray equipment. Furthermore, a water receiving tray 11 is installed at the bottom of the box body 1. The water receiving tray 11 covers the bottom of the box body 1 and is funnel-shaped. Furthermore, a drain outlet 12 is provided at the lowest point of the water receiving tray 11, and a detachable water tank 13 is provided below the drain outlet 12.

[0032] When it is necessary to change the fragrance type or clean the entire cabinet 1, replace the external storage bottle. At the same time, remove all the non-woven fabric 00 inside the cabinet 1, open the spray pipe 9 to spray cleaning liquid, clean the inside of the cabinet 1 and deodorize it. The water tray 11 at the bottom of the cabinet 1 will collect the waste liquid after cleaning. The waste liquid will flow to the lowest point of the water tray 11 and flow into the water tank 13 from the drain outlet 12.

[0033] The implementation principle of this application embodiment is as follows: During the operation of the device for scenting non-woven fabric, the non-woven fabric 00 first enters the box 1 from the feed port 6. The non-woven fabric 00 is alternately pulled by the upper and lower layers of staggered conveyor rollers. The upper conveyor roller 301 bends the non-woven fabric 00 upward, while the lower conveyor roller 302 bends it downward. This way of traveling not only prolongs the movement trajectory of the non-woven fabric 00 in the box 1, but also fully exposes both sides of it.

[0034] After the non-woven fabric 00 enters, the operator uses the spray device 2 to spray a mist of fragrance into the chamber 1. At the same time, the fans 4 installed on both sides of the inner wall of the chamber 1 are activated, and the fragrance mist particles are dispersed and accelerated through directional airflow. As the non-woven fabric 00 moves up and down through the mist of fragrance, the fragrance adheres to the surface of the non-woven fabric 00 under the action of airflow. The scented non-woven fabric 00 continues to move towards the discharge port 7, where the curtain 8 effectively prevents the fragrance from escaping from the chamber 1.

[0035] When the fragrance needs to be changed or maintenance is required, the operator can activate the top spray pipe 9 for a thorough cleaning. The inclined water tray 11 automatically collects the wastewater and directs it to the water tank 13.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
