Description

Technical Field

[0001] The present invention relates to a device suitable for spraying non-woven fabrics, and more particularly to a functional layer spraying device for non-woven fabrics. Background Art

[0002] The functional layer spraying of non-woven fabrics mainly uses spraying technology to evenly apply coatings or solutions with specific functions to the surface of non-woven fabrics, thereby giving them various functionalities. First, the non-woven fabric is pretreated, such as removing impurities such as oil and dust on the surface to ensure the adhesion of the coating. Then, according to the needs, the appropriate coating and spraying equipment are selected to carry out the spraying operation. After the spraying is completed, the non-woven fabric usually needs to be dried and cured so that the coating and the non-woven fabric are tightly combined to form a stable functional surface. Usually, the functional layer of non-woven fabrics is a hydrophilic and breathable coating, a waterproof and moisture-permeable coating, an antibacterial and deodorizing coating, an anti-ultraviolet coating, and an anti-static coating. However, the existing technology still has the following problems: there are usually certain gaps between the fibers of non-woven fabrics, and the spraying devices used on the market use ultrasonic spraying and high-pressure nozzles to increase the impact force to accelerate the penetration of the paint into the pores of the non-woven fabric. The use of ultrasonic spraying is slow and cannot meet the needs of rapid production. Secondly, the use of high-pressure nozzles to increase the impact force to accelerate the penetration of the paint into the non-woven fabric has a large impact force on the paint sprayed by the high-pressure nozzle, which can easily lead to local coating accumulation and uneven overall coating thickness, resulting in uneven production of the functional layer and a high defective rate. Therefore, we propose a functional layer spraying device for non-woven fabrics. Summary of the Invention

[0010] Optionally, a plurality of groups of uniform holes are provided on one side of the uniform plate, and one side inside the plurality of groups of uniform holes is inclined.

[0012] Optionally, a driving gear plate is fixedly installed on the outside of the lifting sleeve, and a driven gear meshing with the driving gear plate is fixedly installed on one end of one set of winding wheels.

And relying on the inclined angle, V-shaped groove and V-shaped scraper plate design, it can avoid the scraped waste material from dripping onto the non-woven fabric and affecting the uniformity of the sprayed coating.

Detailed implementation manners

[0019] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention, its application, or use.

[0021] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered as part of the specification.

[0022] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0023] As Figures 1 - 16 shown, a spraying device for a functional layer of non-woven fabric includes a spraying support base 1, a spraying box 2, and a non-woven fabric transmission mechanism 3. Inside the spraying box 2, there are multiple groups of transmission rollers 5 driven and connected through the non-woven fabric transmission mechanism 3. It further includes: an auxiliary penetration mechanism 4 and a transmission mechanism 6. The auxiliary penetration mechanism 4 includes two groups of fabric pressing plates 403. A material pressing area is formed between the two groups of fabric pressing plates 403. The transmission mechanism 6 is arranged on one side of the spraying box 2, and both groups of fabric pressing plates 403 rotate closer to or away from each other through the transmission mechanism 6; Due to the design that both groups of fabric pressing plates 403 rotate closer to or away from each other through the transmission mechanism 6, the two groups of fabric pressing plates 403 can squeeze the non-woven fabric by approaching each other, thereby accelerating the penetration speed of the coating on the surface of the non-woven fabric, improving the forming speed of the functional layer, and the impact force of the auxiliary nozzle further accelerates the formation of the functional layer.

[0024] In addition, it should be noted that by changing the impact force of the nozzle, local coating accumulation is likely to occur. Therefore, in the present invention, by using two groups of fabric pressing plates 403 to squeeze the non-woven fabric, it is more efficient to increase the penetration speed of the coating and can avoid coating accumulation.

[0025] A waste scraping mechanism 10, which includes two groups of scrapers 102 and two groups of driving components 101. Both groups of driving components 101 are in transmission connection with the transmission mechanism 6, and both groups of scrapers 102 are slidably arranged inside the spraying box 2 through the driving components 101, and the scrapers 102 contact the surface of the fabric pressing plates 403 through the driving components 101.

[0026] As Figures 1 to 15As shown, due to the design that the scraper 102 contacts the surface of the cloth pressing plate 403 through the driving component 101, the scraper 102 can contact the side of the cloth pressing plate 403 that contacts the non-woven fabric, thereby scraping off the paint attached to the pressing surface of the cloth pressing plate 403, avoiding the accumulation of the attached paint, which leads to uneven coating when the cloth pressing plate 403 squeezes the non-woven fabric surface later.

[0027] Furthermore, a rotating gear 401 is fixedly mounted on one end of the material pressing plate 403, and a lifting hole 8 is opened on one side of the spray box 2. Two sets of sliding sleeves 402 are slidably mounted inside the lifting hole 8. The sliding sleeves 402 are rotatably sleeved on the outer side of the rotating gear 401, and one set of the rotating gears 401 is in transmission connection with the transmission mechanism 6; like Figures 1 to 15 As shown, by the design that the sliding sleeve 402 is rotatably sleeved on the outside of the rotating gear 401, the rotating gear 401 can rotate and, at the same time, can also realize linear lifting motion along the guiding effect of the lifting hole 8, so that the cloth pressing plate 403 can not only be lifted and slid, but also rotate.

[0028] Furthermore, a V-shaped groove is provided on one side of the cloth pressing plate 403, and teeth 9 are provided on one end of both sides of the lifting hole 8 to engage with the rotating gear 401; Through the design of the engagement between the rotating gear 401 and the teeth 9, when the cloth pressing plate 403 is lifted and slid to a certain position, it will rotate through the engagement transmission of the rotating gear 401 and the teeth 9, and one side of the cloth pressing plate 403 will tilt downward, thereby facilitating the paint attached to the surface of the cloth pressing plate 403 to accumulate and drip along the inclined angle.

[0029] like Figures 1 to 15 As shown, by the design of a V-shaped groove on one side of the cloth pressing plate 403, when the paint is accumulated along the inclined angle, the accumulated paint can follow the design of the V-shaped groove and gradually accumulate along the V-shaped edge toward the two ends of the cloth pressing plate 403, thereby effectively preventing the paint from dripping onto the non-woven fabric and causing uneven coating.

[0030] Secondly, if Figure 15 As shown, the other side of the fabric pressing plate 403 is V-shaped, which complements the V-shaped groove, so that the V-shaped groove can be evenly filled, avoiding the fabric pressing plate 403 squeezing the non-woven fabric surface to cause uneven coating.

[0031] Furthermore, the transmission mechanism 6 includes a rotating disk 601 and a lifting sleeve 602. The rotating disk 601 is rotatably arranged on one side of the spray box 2 by being connected to one set of transmission rollers 5. One end of the lifting sleeve 602 is sleeved on the outside of one set of rotating gears 401. A docking rod 603 is provided on one end of one side of the rotating disk 601. The docking rod 603 is located in the hollow area of the lifting sleeve 602. likeFigures 1 to 15 As shown, through the design that one end of the lifting sleeve 602 is sleeved outside one set of rotating gears 401, when one set of transmission rollers 5 rotates and transports the non-woven fabric through the non-woven fabric transmission mechanism 3, one set of transmission rollers 5 will drive the rotating disk 601 to rotate. At the same time, the rotating disk 601 can control the lifting sleeve 602 to slide up and down along the lifting hole 8 through the docking rod 603, so that during the spraying and transportation of the non-woven fabric, the fabric pressing plate 403 can continuously press the surface of the non-woven fabric.

[0032] Specifically, as Figure 4 and Figure 5 shown, an adjustment groove is formed at one end on one side of the rotating disk 601, and an adjustment screw rod 604 is rotatably connected inside the adjustment groove. The end of the docking rod 603 is threadedly sleeved outside the adjustment screw rod 604.

[0033] As Figure 5 shown, one end of the adjustment screw rod 604 extends out of the adjustment groove, which is convenient for the staff to manually adjust. Thus, the docking rod 603 can adjust the position close to the center point of the rotating disk 601 according to the usage situation, and can adjust the frequency of the rotating disk 601 driving the fabric pressing plate 403 to move up and down repeatedly in cooperation with the docking rod 603 according to non-woven fabrics of different thicknesses.

[0034] Furthermore, connection shafts 105 are rotatably connected to the same ends of the two fabric pressing plates 403. A sliding groove is formed on one side inside the spraying box 2. Linkage toothed plates 103 are fixedly installed at one ends of the two connection shafts 105. The linkage toothed plates 103 are slidably installed inside the sliding groove. A linkage gear 104 is rotatably connected to the center inside the sliding groove. The two linkage toothed plates 103 are both meshed with the linkage gear 104; As Figures 1 to 15 shown, through the design that the two linkage toothed plates 103 are both meshed with the linkage gear 104, when the lifting sleeve 602 drives the lower fabric pressing plate 403 to slide up and down through one set of rotating gears 401, the lower fabric pressing plate 403 can rotate through the linkage gear 104, so that the two linkage toothed plates 103 slide in opposite directions, thereby realizing the sliding of the two fabric pressing plates 403 moving away from each other simultaneously, achieving the extrusion of the upper and lower surfaces of the non-woven fabric and effectively accelerating the penetration speed of the coating.

[0035] Furthermore, the scraper 102 is composed of a scraping plate 1021 and a uniform plate 1023. One side of the scraping plate 1021 is arranged in a V shape. The uniform plate 1023 is fixedly installed on one side of the scraping plate 1021, and a scraping cavity is formed between the uniform plate 1023 and the scraping plate 1021; As Figures 1 to 15As shown, through the design of one side of the scraping plate 1021 being V-shaped, one side of the scraping plate 1021 faces the V-shaped groove. Thus, when the scraping plate 1021 slides while adhering to the surface of the fabric pressing plate 403, the surplus material can be pushed to both ends of the scraping plate 1021 by one side of the V-shape, which is also both ends of the fabric pressing plate 403. Therefore, through the mutual cooperation of the scraping plate 1021 with one side being V-shaped and the fabric pressing plate 403 provided with a V-shaped groove, it can well avoid the surplus material dripping onto the surface of the non-woven fabric and effectively accumulate and concentrate the surplus material together for recycling.

[0036] Furthermore, multiple groups of uniform holes are provided on one side of the uniform plate 1023, and one side inside each of the multiple groups of uniform holes is inclined. As Figures 1 to 15 shown, through the design of multiple groups of uniform holes being provided on one side of the uniform plate 1023, the uniform plate 1023 acts in front of the scraping plate 1021. The uniform plate 1023 can separate the surplus material adhering to the fabric pressing plate 403, and can avoid the surplus material being too concentrated, resulting in the scraping plate 1021 being unable to quickly push the surplus material along the V-shaped edge to both ends of the fabric pressing plate 403. It should be noted that the above-mentioned uniform holes are inclined on one side inside, which can better evenly separate the surplus material and enable the surplus material to enter the scraping cavity faster along the inclined surface and be pushed away by the scraping plate 1021.

[0037] Specifically, as Figure 11 shown, the upper surface of the above-mentioned scraping plate 1021 is inclined, and the inclined angle is the same as the angle after the fabric pressing plate 403 rotates, so as to better scrape off the surplus material. And a first anti-overflow groove 1022 is provided on one side of the scraping plate 1021, and the first anti-overflow groove 1022 is arc-shaped. A second anti-overflow groove 1024 is provided on one side of the uniform plate 1023, and multiple groups of uniform holes communicate with the second anti-overflow groove 1024, and the second anti-overflow groove 1024 is arc-shaped.

[0038] Through the design that both the first anti-overflow groove 1022 and the second anti-overflow groove 1024 are arc-shaped, it can well avoid that when the scraping plate 1021 and the uniform plate 1023 scrape off a large amount of surplus material, the height of the accumulated surplus material becomes too high, thus exceeding the thickness of the scraping plate 1021 and the uniform plate 1023 and resulting in the inability to scrape off all the surplus material.

[0039] It is worth noting that when the scraping plate 1021 and the uniform plate 1023 scrape off the surplus material, a large amount of surplus material can follow the arc characteristics of the first anti-overflow groove 1022 and the second anti-overflow groove 1024 and turn over like a wave, so as to avoid the height of the accumulated surplus material exceeding the height of the scraping plate 1021 and the uniform plate 1023.

[0040] Further, the driving component 101 includes two sets of winding wheels 1017. Both sets of winding wheels 1017 are rotatably installed inside the spraying box 2. One of the sets of winding wheels 1017 is in transmission connection with the lifting sleeve 602. Pulling ropes 1012 are wound and connected to both sets of winding wheels 1017. A sliding seat 1011 fixedly installed with the scraping plate 1021 is arranged between the two pulling ropes 1012. The sliding seat 1011 is slidably installed inside the spraying box 2. A driving gear plate 1015 is fixedly installed on the outer side of the lifting sleeve 602. A driven gear 1013 meshing with the driving gear plate 1015 is fixedly installed at one end of one of the sets of winding wheels 1017. The driving gear plate 1015 is slidably installed outside the spraying box 2. A synchronization mechanism 1016 is jointly arranged between one of the sets of winding wheels 1017 included in the two driving components 101. Thus, the two sets of winding wheels 1017 are synchronously rotated through the synchronization mechanism 1016. Exemplarily, the above-mentioned synchronization mechanism 1016 adopts the structure of two synchronous wheels and a synchronous belt to achieve synchronous transmission. The structure of using a synchronous wheel in cooperation with a synchronous belt to achieve synchronous transmission has already become a mature existing technology. Those skilled in the art should know how to install and use the synchronization mechanism 1016 to achieve the synchronous rotation of the two sets of winding wheels 1017. Therefore, the present invention will not elaborate herein.

[0041] Through the design of the synchronization mechanism 1016, when the driving gear plate 1015 drives one of the sets of winding wheels 1017 to rotate through the driven gear 1013, one of the sets of winding wheels 1017 included in the other driving component 101 can achieve synchronous rotation through the synchronization mechanism 1016. Thus, the synchronous movement of the two scraping plates 102 can be realized to respectively scrape the surplus materials on the upper and lower sets of fabric pressing plates 403.

[0042] As Figures 1 to 15 shown, through the design that a sliding seat 1011 fixedly installed with the scraping plate 1021 is arranged between the two pulling ropes 1012, when the fabric pressing plate 403 rotates by an angle and continues to slide, the driving gear plate 1015 will mesh with the driven gear 1013, causing one of the sets of winding wheels 1017 to wind the pulling rope 1012, making the sliding seat 1011 drive the scraping plate 102 to slide. The scraping plate 102 moves to the surface of the fabric pressing plate 403 to scrape the surplus materials attached to its surface.

[0043] Specifically, as Figure 7As shown, a guide groove 7 for guiding the pull rope 1012 is opened inside the spray box 2, and the pull rope 1012 is located inside the guide groove 7. The guide groove 7 is opened to bypass the lifting hole 8, and mounting grooves are opened at both ends of the guide groove 7, and a mounting shell 1014 is provided inside the mounting groove. Two sets of winding wheels 1017 are rotatably installed inside the mounting shells 1014, and the driven gear 1013 is rotatably installed in one set of mounting shells 1014. A transmission groove is opened on the outside of the spray box 2, the driven gear 1013 is located inside the transmission groove, and the driving gear plate 1015 is slidably installed inside the transmission groove; It should be noted that Figure 7 Only the guide groove 7 opened at the bottom is shown. There are two groups of guide grooves 7, which are located at the upper and lower ends of the lifting hole 8 respectively, and the lifting hole 8 and the guide groove 7 are not interconnected.

[0044] The synchronization mechanism 1016 is disposed between the two sets of mounting shells 1014 , and the two sets of mounting slots are communicated with each other, and the synchronization mechanism 1016 is disposed at the communication point between the two sets of mounting slots.

[0045] The design of the guide groove 7 can prevent the pull rope 1012 from being located inside the lifting hole 8 and affecting the normal up and down sliding of the sliding sleeve 402.

[0046] It should be noted that if Figure 6 and Figure 8 As shown, one end of the sliding seat 1011 is a rectangular parallelepiped, and the sliding seat 1011 can stably pass through the interior of the lifting hole 8 to prevent the sliding seat 1011 from falling into the lifting hole 8, causing the scraper 102 to be unable to always fit on the surface of the cloth pressing plate 403.

[0047] like Figures 1 to 15 As shown, the clockwork spring 11 mentioned above can rotate one set of winding wheels 1017 when the cloth pressing plate 403 is close to the non-woven fabric for squeezing, and the other set of winding wheels 1017 can retract the winding rope 1012 through the action of the clockwork spring 11, so that the scraper 102 is reset to the initial position, making it convenient for the subsequent repeated scraping of residual material on the surface of the cloth pressing plate 403.

[0048] Therefore, the present invention adopts a simple structural linkage to effectively reduce the use cost of the spraying device, while accelerating the speed of forming the functional layer sprayed by the functional layer spraying device on the surface of the non-woven fabric, thereby further improving the practicality of the spraying device.

[0049] Furthermore, one end of another set of winding wheels 1017 is connected to a spring spring 11, and two sets of sliding grooves are provided on both sides of the interior of the spray box 2, one set of sliding grooves on both sides is inclined, and the other set of sliding grooves on one side is horizontally arranged; It is worth noting that if Figure 7As shown, one set of the above-mentioned sliding grooves is inclined, and the inclination angle of one set of sliding grooves is larger than the inclination state angle after the fabric pressing plate 403 rotates, so as to ensure that the scraper 102 can fit on the surface of the fabric pressing plate 403 during the descending process, and stably scrape off the remaining materials.

[0050] Secondly, the other set of sliding grooves is horizontally arranged. When the upper fabric pressing plate 403 slides upward and rotates, the upper scraper 102 can slide horizontally and cooperate with the angle after the fabric pressing plate 403 rotates, and always fit on the pressing surface of the upper fabric pressing plate 403. Therefore, the two sets of sliding grooves are respectively inclined and horizontally designed, and can respectively achieve the effect that the scraper 102 always fits on the upper surface of the fabric pressing plate 403 to scrape off the remaining materials.

[0051] As Figures 1 to 15 shown, it should be noted that the two sets of fabric pressing plates 403 above can rotate synchronously and in the same direction through the teeth 9, and are both inclined at the same angle, so as to ensure that the scraped remaining materials are piled up together for collection.

[0052] It should be noted that through the design of the docking rod 603 adjusting the screw rod 604 to realize the adjustable repeated lifting frequency of the fabric pressing plate 403 in the above, when the repeated lifting frequency of the fabric pressing plate 403 of the present invention is too large, the moving distance of the scraper 102 driven by the driving tooth plate 1015 and the driven gear 1013 can still exceed the width of the fabric pressing plate 403. Therefore, the moving distance of the scraper 102 is larger than the width of the fabric pressing plate 403. Thus, when the lifting frequency of the fabric pressing plate 403 is too fast, the scraper 102 can still completely cover and scrape the surface of the fabric pressing plate 403, effectively avoiding the remaining materials staying on the surface of the fabric pressing plate 403.

[0053] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
