Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric deep processing technology, and in particular to a device for impregnating nonwoven fabrics with natural plant extracts. Background Technology

[0002] Many natural plant extracts have antibacterial and anti-inflammatory effects. For example, extracts from plants such as honeysuckle, chamomile, and licorice can be gently applied to the skin surface to achieve antibacterial effects. Compared with chemical disinfectants, natural plant extracts are safer and less harmful to human health and the environment, meeting people's pursuit of green and environmentally friendly products. Therefore, they have broad application prospects in the field of non-woven fabric impregnation. Although some existing non-woven fabric antibacterial impregnation liquid formulas use traditional Chinese medicine, most of them are simple mixtures and lack the theoretical basis of traditional Chinese medicine. This leads to unclear mechanisms of action of the impregnation liquid, affecting the antibacterial effect and other properties of non-woven fabrics. On the other hand, in terms of impregnation equipment and processes, some existing technologies have problems such as cumbersome procedures and waste of resources.

[0003] When manufacturing nonwoven fabrics, they need to be impregnated to ensure their effectiveness. Currently, when using impregnation equipment, the process generally involves placing the fabric in a tank containing water, adding an impregnating agent, and then completing the impregnation process.

[0004] The existing patent (publication number: CN219059370U) discloses an impregnation device for nonwoven fabric production. Through the cooperation between the hydraulic cylinder, the connecting plate, and the extrusion frame, the impregnation device can apply pressure to the fabric submerged in the impregnation tank during use. This ensures the impregnation effect while saving water usage, thereby reducing the overall operating cost of the device. At the same time, it ensures that the fabric is completely impregnated in the water, preventing some fabric from floating on the surface and thus affecting the impregnation effect.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing impregnation devices for natural plant extracts in nonwoven fabrics typically lack an integrated structure for dynamic mixing and circulating filtration, making it difficult to continuously maintain the uniformity and cleanliness of the impregnation solution. This leads to the precipitation of extract components and the presence of impurities, affecting the stability of the impregnation solution and the safety of the product. Furthermore, existing impregnation devices for natural plant extracts in nonwoven fabrics do not facilitate the phased solidification and shaping of the extract, resulting in weak bonding between the extract and the nonwoven fibers, easy loss, and impacting the durability of the product's efficacy.

[0006] To address this, a device for impregnating nonwoven fabrics with natural plant extracts is proposed. Utility Model Content

This device addresses the common problem that existing devices for impregnating nonwoven fabrics with natural plant extracts often lack an integrated structure for dynamic mixing and circulating filtration, making it difficult to maintain the uniformity and cleanliness of the impregnation solution. This results in the precipitation of extract components and the presence of impurities, affecting the stability of the impregnation solution and the safety of the product. Furthermore, existing devices for impregnating nonwoven fabrics with natural plant extracts are not suitable for staged solidification and shaping of the extract, leading to weak bonding between the extract and the nonwoven fibers, easy loss, and affecting the durability of the product's efficacy.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This application achieves the effect of non-woven fabric fully absorbing natural plant extracts and the impregnation liquid being uniform and free of impurities through the dynamic impregnation component, thereby improving the uniformity of impregnation and the stability of product quality. Compared with the traditional impregnation device, which has insufficient impregnation of non-woven fabric, many impurities in the liquid, and easy precipitation of components, this component can realize the functions of adaptive adjustment of impregnation pressure, dynamic mixing of plant extracts and solvents, and circulation filtration and purification. It solves the problems of large differences in the efficacy of non-woven fabric due to uneven impregnation, product safety affected by impurity residue, and precipitation of extract components due to insufficient manual stirring in the traditional method.

[0020] 2. This application achieves a strong bond and stable shaping effect between natural plant extracts and nonwoven fibers through a gradient curing component, improving the durability of the efficacy and structural integrity of the impregnated nonwoven fabric. Compared with traditional curing devices where extracts are not firmly attached and easily lost, product deformation is caused by untimely cooling, and unstable conveying affects the processing effect, this component can realize the function of pre-drying-curing-cooling gradient synergistic processing and stable conveying. It solves the problems of rapid efficacy decay caused by incomplete curing, shrinkage and deformation of nonwoven fabric caused by improper cooling, and uneven local processing caused by conveying deviation in traditional methods.

[0029] 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.

[0030] Please see Figure 1-7 The present invention provides the following technical solution:

[0031] A device for impregnating nonwoven fabrics with natural plant extracts includes a base 1, an impregnation tank 2 fixedly connected to the top of the base 1, a dynamic impregnation component 4 inside the impregnation tank 2, a gradient curing component 5 on the right side of the base 1, the dynamic impregnation component 4 including a lifting cylinder 401 fixedly connected to the top of the impregnation tank 2, a top plate 402 fixedly connected to the output end of the lifting cylinder 401, an impregnation roller 403 fixedly connected to the bottom of the top plate 402, a stirring tank 404 fixedly connected to the top of the impregnation tank 2, a water inlet pipe 405 connected to the top of the stirring tank 404, a circulation pump 406 connected to the outside of the water inlet pipe 405, the water inlet pipe 405 connected to the impregnation tank 2, a filter box 407 connected to the outside of the impregnation tank 2, a circulation pipe 408 connected to the outside of the filter box 407, and the circulation pipe 408 connected to the impregnation tank 2.

[0032] In this embodiment: the rotary motor 10 at the top of the mixing tank 404 drives the stirring blades 11 to rotate, thoroughly mixing the natural plant extracts and water in the mixing tank 404 to form a uniform impregnation solution. The mixed impregnation solution enters the filter box 407 through the connecting pipe 12. After impurities are removed by the filter plate 13, a portion is transported to the impregnation tank 2 through the water inlet pipe 405 under the action of the circulating pump 406 to replenish the liquid level in the tank. At the same time, the conveying rollers 9 on the conveying supports 8 on both sides of the impregnation tank 2 start to rotate, smoothly conveying the nonwoven fabric to be processed into the impregnation tank 2. When the nonwoven fabric enters the impregnation area, the lifting cylinder 401 at the top of the impregnation tank 2 is activated, and its output end pushes... The top plate 402 descends, causing the impregnation roller 403 at the bottom of the top plate 402 to gently press against the surface of the nonwoven fabric. The pressure of the impregnation roller 403 is controlled by adjusting the extension and retraction of the lifting cylinder 401 to ensure that the nonwoven fabric fully adheres to the impregnation liquid in the impregnation tank 2, achieving full impregnation. During the impregnation process, the impregnation liquid in the impregnation tank 2 will continuously flow into the filter box 407 through the outer pipe. After being filtered again by the filter plate 13, it will flow back to the impregnation tank 2 through the circulation pipe 408, forming a dynamic circulation to ensure that the impregnation liquid is always uniform and clean. The impregnated nonwoven fabric flows out from the right side of the impregnation tank 2 under the drive of the conveying roller 9 and enters the auxiliary tank 6. The scraper 7 removes the excess impregnation liquid from the surface, and then it continues to be conveyed forward.

[0033] Specifically, such as Figure 3 As shown, the gradient curing component 5 includes a support frame 501 fixedly connected to the top of the base 1, a hot air circulation fan 502 fixedly connected to the bottom of the support frame 501, and a pre-drying seat 503 connected to the output end of the hot air circulation fan 502.

[0034] Specifically, such as Figure 3 As shown, a curing frame 504 is fixedly connected to the right side of the support frame 501, and a curing lamp tube 505 is installed inside the support frame 501.

[0035] Specifically, such as Figure 3 As shown, guide supports 506 are fixedly connected to both sides of the support frame 501, guide rollers 507 are rotatably connected to the inner side of the guide supports 506, and auxiliary conveying rollers 508 are fixedly connected to the top of the support frame 501.

[0036] In this embodiment: the nonwoven fabric after scraping is conveyed into the support frame 501 of the gradient curing component 5. First, it passes through the guide rollers 507 on the guide supports 506 on both sides of the support frame 501. The guide rollers 507 guide and limit the nonwoven fabric by rotating, ensuring that it enters the pre-drying seat 503 in a stable posture. At this time, the hot air circulation fan 502 at the bottom of the support frame 501 is started, and the heated hot air is sent into the pre-drying seat 503 through the output end. The hot air forms a circulating airflow in the pre-drying seat 503, which preliminarily dries the impregnation liquid on the surface of the nonwoven fabric, evaporates some of the moisture, and allows the extract to initially adhere to the fibers. The pre-dried nonwoven fabric is then conveyed by the auxiliary conveyor rollers at the top of the support frame 501. Driven by 508, the material enters the curing frame 504 on the right. The curing lamp 505 inside the curing frame 504 is powered on and emits light of a specific wavelength. Through photochemical reaction, the extract is firmly bonded to the nonwoven fabric fibers. The cured nonwoven fabric continues to move to the cooling area on the bottom right of the support frame 501. The cooling fan 14 is started, and the generated cold air is blown evenly onto the surface of the nonwoven fabric through the cooling nozzle 15 to cool it quickly and set the impregnation layer. Under the guidance of the guide roller 507, the cooled nonwoven fabric is finally transported to the winding support 16 and wound up by the winding roller 17. The whole process realizes the gradient curing treatment of the impregnated nonwoven fabric, ensuring the durability of the product's efficacy and structural stability.

[0037] Specifically, such as Figure 4 As shown, an auxiliary tank 6 is fixedly connected to the right side of the impregnation tank 2, and a scraper 7 is fixedly connected inside the auxiliary tank 6.

[0038] Specifically, such as Figure 4 As shown, conveyor supports 8 are fixedly connected to both sides of the impregnation tank 2, and conveyor rollers 9 are fixedly connected to the inner side of the conveyor supports 8.

[0039] In this embodiment: By setting up an auxiliary tank 6 and a scraper 7, after the nonwoven fabric completes the impregnation process in the impregnation tank 2, it will continue to move forward and flow out from the right side of the impregnation tank 2. At this time, the auxiliary tank 6 fixed on the right side of the impregnation tank 2 will guide the nonwoven fabric, allowing it to smoothly enter the tank. The scraper 7 inside the auxiliary tank 6 is in close contact with the surface of the nonwoven fabric. As the nonwoven fabric continues to move, the scraper 7 will scrape off the excess natural plant extract impregnation liquid adhering to its surface, ensuring that the impregnation amount on the surface of the nonwoven fabric is uniform and consistent, avoiding problems such as clumping or uneven efficacy during the subsequent curing process due to local liquid accumulation. The scraped-off excess impregnation liquid will flow along the inner wall of the auxiliary tank 6 to the bottom of the tank, and then flow back into the impregnation tank 2 through the connecting pipe between the tank and the impregnation tank 2, realizing the impregnation process. The recycling of the impregnation liquid is achieved by setting up a conveyor support 8 and a conveyor roller 9. Before the device is started, the roll of nonwoven fabric to be impregnated is placed next to the conveyor support 8 at the input end of the device. One end of the nonwoven fabric passes through the conveyor roller 9 inside the conveyor support 8. The conveyor support 8 provides stable support for the conveyor roller 9, ensuring that the conveyor roller 9 will not deviate during rotation. When the device starts running, the conveyor roller 9 rotates under the drive of the drive structure. The friction between its surface and the nonwoven fabric will drive the nonwoven fabric forward, smoothly introducing the nonwoven fabric into the impregnation area inside the impregnation tank 2. After the nonwoven fabric has been impregnated and excess impregnation liquid has been scraped off, the conveyor support 8 and the conveyor roller 9 on the other side of the impregnation tank 2 will continue to receive and convey the nonwoven fabric, allowing it to smoothly enter the subsequent gradient curing component 5.

[0040] Specifically, such as Figure 5 As shown, a rotary motor 10 is fixedly connected to the top of the mixing tank 404, and a stirring blade 11 is fixedly connected to the output end of the rotary motor 10. A connecting pipe 12 is connected to the outside of the mixing tank 404, and the connecting pipe 12 is connected to the filter box 407. A filter plate 13 is slidably connected inside the filter box 407.

[0041] Specifically, such as Figure 6 As shown, a cooling fan 14 is fixedly connected to the right side of the bottom of the support frame 501, and a cooling nozzle 15 is connected to the top of the cooling fan 14.

[0042] In this embodiment: By setting up a rotary motor 10, stirring blades 11, connecting pipe 12, and filter plate 13, the rotary motor 10 at the top of the stirring tank 404 is started. The output end of the rotary motor 10 drives the fixedly connected stirring blades 11 to rotate at high speed inside the stirring tank 404. During the rotation, the stirring blades 11 continuously cut and agitate the liquid inside the tank, so that the natural plant extract and water are fully mixed to form a uniform impurity solution, avoiding precipitation or stratification of the extract due to standing. The mixed impurity solution flows into the filter box 407 through the connecting pipe 12 connected to the outside of the stirring tank 404. The filter plate 13 inside the filter box 407 filters the impurity solution, intercepting any plant residues, undissolved particles, and other impurities that may be present, ensuring that the impurity solution entering the subsequent circulation is clean and free of impurities. Part of the filtered impurity solution is transported to the impurity tank 2 through the circulation structure, and the other part can flow back to the stirring tank 404 through other pipes, forming a dynamic circulation. When the surface of the filter plate 13... When impurities accumulate, they can be slid out of the filter box 407 for cleaning or replacement to ensure a continuous and stable filtration effect, ultimately providing high-quality impregnation liquid for the nonwoven fabric and improving the quality of the impregnated product. By setting up a cooling fan 14 and a cooling spray pipe 15, when the nonwoven fabric, after being treated by the curing lamp 505 in the curing frame 504, continues to move forward and reaches the cooling area on the right side of the bottom of the support frame 501, the cooling fan 14 fixed at the bottom of the support frame 501 starts. The cold air generated by the cooling fan 14 will be evenly blown onto the surface of the nonwoven fabric through the cooling spray pipe 15 connected at the top. The outlet of the cooling spray pipe 15 is distributed in a diffused manner, which can make the cold air cover the entire width of the nonwoven fabric, ensuring that all parts of the nonwoven fabric can be uniformly cooled. After the cold air comes into contact with the high-temperature impregnation layer on the surface of the nonwoven fabric, it will quickly remove the heat, so that the temperature of the cured impregnation layer will drop rapidly and set, avoiding shrinkage or deformation of the nonwoven fabric due to excessive temperature, or softening or adhesion of the impregnation layer.

[0043] Specifically, such as Figure 6 As shown, a winding support 16 is fixedly connected to the right side of the base 1, and a winding roller 17 is fixedly connected inside the winding support 16.

[0044] Specifically, such as Figure 4 As shown, a control main board 3 is provided on the outside of the immersion tank 2, and a drain pipe 18 is connected to the bottom of the immersion tank 2. A control valve 19 is provided on the outside of the drain pipe 18.

[0045] In this embodiment: by setting up a winding support 16 and a winding roller 17, the winding roller 17 rotates under the drive of the drive device, which can neatly wind and store the non-woven fabric after a series of treatments such as impregnation, curing, and cooling, avoiding the non-woven fabric from becoming loose, wrinkled, or tangled after processing, and ensuring the product's shape is regular. By setting up a control board 3, a drain pipe 18, and a control valve 19, the control board 3 can centrally monitor and regulate the operating parameters of various components such as the dynamic impregnation component 4 and the gradient curing component 5. Through precise control, the coordination of each link is achieved, ensuring that the impregnation, curing and other processing processes are stable and controllable, and avoiding product quality differences caused by parameter fluctuations. The drain pipe 18 at the bottom of the impregnation tank 2 cooperates with the control valve 19, which can quickly discharge the residual liquid or waste liquid in the impregnation tank 2 by opening the control valve 19 when it is necessary to replace the impregnation liquid, clean the equipment, or discharge the waste liquid.

[0046] Working Principle: In the process of using this nonwoven fabric natural plant extract impregnation device, the roll of nonwoven fabric to be treated is first placed at the input end of the device. One end of the nonwoven fabric is introduced into the impregnation tank 2 via the conveying roller 9 on the conveying support 8. When the nonwoven fabric enters the impregnation tank 2 area, the control main board 3 will activate the lifting cylinder 401 in the dynamic impregnation component 4 according to preset parameters. The output end of the lifting cylinder 401 extends downward, causing the connected top plate 402 to descend synchronously. The impregnation roller 403 at the bottom of the top plate 402 then approaches and gently presses against the surface of the nonwoven fabric. By adjusting the extension and retraction of the lifting cylinder 401, the pressure of the impregnation roller 403 on the nonwoven fabric can be controlled, ensuring that the nonwoven fabric fully adheres to the natural plant extract impregnation solution in the impregnation tank 2, avoiding... Because the fabric floats, some areas do not come into contact with the impregnation liquid, affecting the impregnation effect. Simultaneously, the mixing tank 404 starts working, with its top rotary motor 10 energized, driving the agitator blades 11 connected to the output end to rotate at high speed within the mixing tank 404. This thoroughly mixes the pre-added natural plant extracts and water to form a uniform impregnation liquid. During the mixing process, the circulation pump 406 starts, pumping the initially mixed impregnation liquid from the mixing tank 404 into the impregnation tank 2 through the water inlet pipe 405 to replenish the liquid level. The impregnation liquid in the impregnation tank 2 flows into the filter box 407 through an external connecting pipe. After being filtered by the filter plate 13 inside the filter box 407, any plant residues or impurities that may be present in the impregnation liquid are removed. The filtered clean impregnation liquid is then... The impregnating solution is returned to the impregnation tank 2 via the circulation pipe 408, forming a closed-loop circulation system. This ensures uniform concentration of the impregnation solution and prevents impurities from clogging the pipes or adhering to the surface of the nonwoven fabric, affecting product quality. After the nonwoven fabric fully absorbs the impregnation solution under the pressure of the impregnation roller 403, it continues to move forward and flows out from the right side of the impregnation tank 2, then enters the auxiliary tank 6. The scraper 7 inside the auxiliary tank 6 is in close contact with the surface of the nonwoven fabric. During the movement of the nonwoven fabric, the scraper 7 scrapes off the excess impregnation solution on its surface, keeping the impregnation amount uniform. The scraped-off excess impregnation solution flows back to the bottom of the auxiliary tank 6 and is then returned to the impregnation tank 2 through the pipe, realizing resource recycling. The nonwoven fabric that has undergone scraping treatment is then conveyed to the gradient curing component 5, first passing through the support... Guide rollers 507 on the guide supports 506 on both sides of the support frame 501 guide and limit the nonwoven fabric through their own rotation, ensuring that it enters the pre-drying seat 503 in a stable posture. At this time, the hot air circulation fan 502 at the bottom of the support frame 501 starts, sending heated hot air into the pre-drying seat 503 through the output end. The hot air forms a circulating airflow in the pre-drying seat 503, which preliminarily dries the impregnation liquid on the surface of the nonwoven fabric, evaporating some of the moisture, so that the effective components in the impregnation liquid initially adhere to the nonwoven fabric fibers, avoiding the phenomenon of dripping in subsequent processing. The pre-dried nonwoven fabric enters the curing frame 504 under the drive of the auxiliary conveyor roller 508, and then the curing lamp 505 inside the curing frame 504 is energized to emit light.The system emits light of a specific wavelength to solidify the impregnation solution on the surface of the nonwoven fabric. Through a photochemical reaction, the effective components of the natural plant extracts are firmly bonded to the nonwoven fibers, enhancing adhesion and preventing extract loss during subsequent use. The solidified nonwoven fabric continues to move forward, reaching the cooling area on the right side of the support frame 501. The cooling fan 14 on the bottom right side of the support frame 501 is activated, and the generated cold air is evenly blown onto the surface of the nonwoven fabric through the cooling nozzle 15 connected to the top, rapidly cooling it and setting the solidified impregnated layer. This prevents deformation of the nonwoven fabric or changes in the properties of the impregnated layer due to excessive temperature. Guided by the guide roller 507, the cooled nonwoven fabric finally reaches the winding support 16. The winding roller 17 inside the winding support 16 rotates under the drive of the drive device, neatly winding the treated nonwoven fabric onto the roller, completing the entire impregnation and curing process.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
