Detailed Description of the Embodiments

[0077] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0078] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0081] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of this application are described from the angles shown in the accompanying drawings and should not be construed as limitations on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0082] Such as Figure 1 and Figure 2As shown in the figure, an edge sealing device is provided in an embodiment of the present application, which includes a frame 1 and a glue coating assembly 2. A first fabric guiding roller 11 and a second fabric guiding roller 12 are arranged on the frame 1, and the filter material 6 is transmitted between the first fabric guiding roller 11 and the second fabric guiding roller 12; the glue coating assembly 2 is connected to the frame 1, and the glue coating assembly 2 includes a glue coating part 2231, and the glue coating part 2231 is used to contact the edge of the filter material 6 for glue coating.

[0083] Among them, the filter material 6 can be a particle-containing fabric, that is, fine particles such as activated carbon, alumina, molecular sieve, etc. can be filled between the fabrics. Of course, it can also be other filter materials 6 that need to be edge-sealed with glue. The unsealed filter material 6 can be wound around the first fabric guiding roller 11, and one end of the filter material 6 can be wound around the second fabric guiding roller 12, so that the first fabric guiding roller 11 serves as an input roller and the second fabric guiding roller 12 serves as an output roller. The filter material 6 can continuously and constantly be transmitted from the first fabric guiding roller 11 to the second fabric guiding roller 12, and during the transmission process, the edge of the filter material 6 can be edge-sealed with glue through the glue coating assembly 2. Among them, the glue coating assembly 2 includes a glue coating part 2231, and there is a glue layer on the glue coating part 2231. When the filter material 6 passes by the glue coating part 2231 during transmission, the edge of the filter material 6 will contact the glue layer on the glue coating part 2231 and achieve edge-sealing with glue.

[0084] Therefore, through the edge sealing device provided in the embodiment of the present application, only by making the filter material 6 continuously be transmitted at a set speed, edge-sealing with glue can be achieved when the filter material 6 passes through the glue coating assembly 2, thereby improving the glue coating speed, improving production efficiency, and the structure of the glue coating assembly 2 is simple, saving costs.

[0085] As Figures 2 to 4 shown, as a specific implementation manner, the glue coating assembly 2 specifically includes a driving mechanism 21, a glue coating roller group 22, and a glue coating mechanism 23; among them, the glue coating roller group 22 is in transmission connection with the driving mechanism 21, and the glue coating roller group 22 includes the above-mentioned glue coating part 2231; the glue coating mechanism 23 is arranged on the frame 1 and is located on one side of the glue coating roller group 22, and is used to spray glue onto the glue coating part 2231 to form a glue layer with a set thickness on the glue coating part 2231.

[0086] Specifically, the glue coating assembly 2 can be installed on the frame 1 of the edge sealing device, so that the edge of the filter material 6 can contact the glue coating part 2231 on the glue coating roller group 22. When the driving mechanism 21 is started, the driving mechanism 21 can control the rotation of the glue coating roller group 22, so that the movement tangent direction of the contact part between the glue coating part 2231 and the filter material 6 is consistent with the transmission direction of the filter material 6. The glue coating mechanism 23 can spray glue onto the glue coating part 2231, so that a glue layer with a set thickness can be formed on the surface of the glue coating part 2231. When the edge of the filter material 6 passes by the glue coating part 2231, the glue layer on the glue coating part 2231 can adhere to the edge of the filter material 6 to achieve edge-sealing with glue for the filter material 6.

[0087] As a specific implementation method, as Figures 2 to 4 shown, the glue coating assembly 2 further includes a glue scraping mechanism 24. A gap is maintained between the glue scraping mechanism 24 and the glue coating part 2231, which is used to form a glue layer with a set thickness on the surface of the glue coating part 2231. It can be understood that the glue coating mechanism 23 can only spray glue onto the glue coating part 2231 in a relatively single direction, and only through the rotation of the glue coating part 2231 can the glue be sprayed comprehensively in the circumferential direction of the glue coating part 2231. However, this glue spraying method is difficult to ensure that the thickness of the glue liquid at each position on the surface of the glue coating part 2231 is uniform.

[0088] For this reason, the glue scraping mechanism 24 is designed in this embodiment. A relatively constant gap can be maintained between the glue scraping mechanism 24 and the glue coating part 2231. After the glue coating mechanism 23 sprays glue onto the glue coating part 2231, when the glue coating roller set 22 is rotated by the driving mechanism 21, the glue layer with an excessive thickness on the glue coating part 2231 can be smoothed by the glue scraping mechanism 24. When the glue coating part 2231 rotates one week, the glue scraping mechanism 24 can ensure that the thickness of the glue liquid at each position in the circumferential direction of the glue coating part 2231 is consistent, thereby ensuring the consistency of the edge sealing of the filter material 6.

[0089] As a specific implementation method, as Figures 2 to 4 shown, the glue scraping mechanism 24 includes a scraper 241, a connecting rod 242, and an adjusting nut 243. The connecting rod 242 is threadedly connected to the adjusting nut 243. The scraper 241 is connected to the end of the connecting rod 242, and a gap is maintained between the scraper 241 and the surface of the glue coating part 2231.

[0090] Among them, the connecting rod 242 can be connected to the frame 1 of the edge sealing device through the adjusting nut 243. When the adjusting nut 243 is rotated, the connecting rod 242 can be moved axially, thereby realizing the adjustment of the distance between the scraper 241 and the glue coating part 2231, that is, realizing the adjustment of the thickness of the glue layer on the glue coating part 2231, so that the glue coating assembly 2 can meet the glue coating and edge sealing requirements for filter materials 6 with different thicknesses and achieve versatility.

[0091] As a specific implementation method, as Figure 3 , Figure 4 and Figure 6 shown, the glue coating roller set 22 includes an upper roller 221, a lower roller 222, and a glue coating roller 223. The upper roller 221 and the lower roller 222 are both sleeved on the glue coating roller 223. A distance is maintained between the upper roller 221 and the lower roller 222. The part of the glue coating roller 223 located between the upper roller 221 and the lower roller 222 forms the glue coating part 2231.

[0092] Among them, a groove structure is formed between the upper roller 221, the lower roller 222 and the glue - applying roller 223. The distance between the upper roller 221 and the lower roller 222 is the width of the groove structure, and the distance between the upper roller 221 and the glue - applying roller 223 in the radial direction is the depth of the groove structure. In this embodiment, the width of the groove structure can be slightly larger than the thickness of the filter material 6. For example, when the thickness of the filter material 6 is 1.5 mm, the width of the groove structure can be 1.6 mm; when the thickness of the filter material 6 is 2.0 mm, the width of the groove structure can be 2.1 mm. Thus, it can not only ensure that the filter material 6 can be stably and normally transported in the groove structure, but also ensure the uniformity of gluing the filter material 6.

[0093] Among them, for different filter materials 6, the edge sealing width of the filter material 6 may also be different. The edge sealing width of the filter material 6 can be changed by adjusting the thickness of the glue layer on the glue - applying part 2231. When the thickness of the glue layer is larger, the glue - applying width at the edge of the filter material 6 is larger, so that the filter material 6 can have a larger edge sealing width. Correspondingly, when the thickness of the glue layer is smaller, the glue - applying width at the edge of the filter material 6 is smaller, so that the filter material 6 can have a smaller edge sealing width. Specifically, the thickness of the glue layer can be adjusted by adjusting the position of the squeegee 241 relative to the glue - applying part 2231. When the distance between the squeegee 241 and the glue - applying part 2231 is larger, a larger glue layer thickness can be obtained on the glue - applying part 2231. When the distance between the squeegee 241 and the glue - applying part 2231 is smaller, a smaller glue layer thickness can be obtained on the glue - applying part 2231.

[0094] Exemplarily, when edge - sealing the filter material 6 with a thickness of 1.5 mm, the scraping width of the squeegee 241 is 1.5 mm, and at the same time, the distance between the squeegee 241 and the glue - applying part 2231 can be made smaller to make the glue layer thickness on the glue - applying part 2231 smaller, so that the filter material 6 can have an edge sealing width of 1.0 mm. When edge - sealing the filter material 6 with a thickness of 2.0 mm, the scraping width of the squeegee 241 is 2.0 mm, and at the same time, the distance between the squeegee 241 and the glue - applying part 2231 can be made larger to make the glue layer thickness on the glue - applying part 2231 larger, so that the filter material 6 can have an edge sealing width of 1.2 mm.

[0095] Specifically, the material of the glue - applying roller 223 can be stainless steel, enabling the glue - applying part 2231 of the stainless - steel material to store a specific thickness of glue, thereby ensuring that the edges of the passing filter material 6 can be fully coated with glue. Among them, the surface with a uniform glue layer on the glue - applying part 2231 is perpendicular to the surface of the filter material 6. Except for this surface with a uniform glue layer, the surfaces of the upper roller 221, the lower roller 222, and the glue - applying roller 223 that can come into contact with the glue can all be provided with a low - surface - energy coating, such as a polytetrafluoroethylene material layer. The low - surface - energy coating can facilitate the flow of the glue, reduce the ability of the glue to adhere to the coating surface, enable the glue to quickly fall into the glue layer below the edge - sealing device for recycling, prevent the glue from accumulating on the surfaces other than the glue - applying part 2231, and at the same time facilitate the cleaning of the surfaces with low surface energy.

[0096] As a specific implementation method, as Figure 3 and Figure 4 shown, the glue - applying roller group 22 further includes a first motor 224 and a first worm 225. One end of the first worm 225 is connected to the first motor 224; the upper roller 221 and the lower roller 222 are respectively rotatably sleeved on the glue - applying roller 223. The upper roller 221 is axially provided with a first threaded hole 2211, and the lower roller 222 is axially provided with a second threaded hole 2221. The rotation directions of the first threaded hole 2211 and the second threaded hole 2221 are opposite, and the first worm 225 is respectively threadedly connected to the first threaded hole 2211 and the second threaded hole 2221.

[0097] Among them, the first worm 225 has threads distributed in a single direction. When the first motor 224 drives the first worm 225 to rotate, the first worm 225 can drive the upper roller 221 and the lower roller 222 to approach or move away from each other through the cooperation with the first threaded hole 2211 and the second threaded hole 2221 with opposite rotation directions, thereby realizing the adjustment of the distance between the upper roller 221 and the lower roller 222, that is, the adjustment of the groove width, so as to be able to meet the requirements of gluing and edge - sealing for filter materials 6 of different thicknesses and achieve versatility.

[0098] As a specific implementation method, as Figure 5 shown, the upper roller 221 and the lower roller 222 are respectively provided with adjustment slots 226. The two ends of the squeegee 241 along the axis of the upper roller 221 are respectively inserted into the corresponding adjustment slots 226, and the length of the squeegee 241 is less than the length of the adjustment slots 226, so that the squeegee 241 can move and adjust in the direction of approaching or moving away from the glue - applying part 2231.

[0099] Among them, by making the length of the squeegee 241 less than the length of the adjustment groove 226, a certain adjustment space can be provided for the squeegee 241 in the adjustment groove 226. Specifically, when gluing and sealing the edge of the filter material 6 with a larger thickness is required, the squeegee 241 can be moved in the adjustment groove 226 in a direction away from the gluing part 2231, so that the distance between the squeegee 241 and the gluing part 2231 can be increased. Furthermore, the thickness of the glue layer on the surface of the gluing part 2231 can be increased, and the requirements for gluing and sealing the edge of the filter material 6 with a larger thickness can be met. Conversely, when gluing and sealing the edge of the filter material 6 with a smaller thickness is required, the squeegee 241 can be moved in the adjustment groove 226 in a direction closer to the gluing part 2231, so that the distance between the squeegee 241 and the gluing part 2231 can be decreased. Furthermore, the thickness of the glue layer on the surface of the gluing part 2231 can be decreased, and the requirements for gluing and sealing the edge of the filter material 6 with a smaller thickness can be met.

[0100] Among them, the squeegee 241 can be inclined relative to the radial direction of the gluing roller 223, so that the scraped glue can fall into the glue tank below the edge sealing device along the squeegee 241, avoiding the accumulation of glue liquid.

[0101] In another implementation, the width dimension of the squeegee 241 in the axial direction of the gluing roller 223 is less than the width of the groove structure. For example, when the width of the groove structure is 1.6 mm, the width of the squeegee 241 is 1.5 mm; when the width of the groove structure is 2.1 mm, the width of the squeegee 241 is 2.0 mm. That is to say, a gap can be maintained between the squeegee 241 and the upper roller 221 and the lower roller 222 in the axial direction of the gluing roller 223, so as to facilitate the movement of the squeegee 241 for convenient position adjustment and cleaning and replacement.

[0102] As a specific implementation, as Figure 3 shown, the gluing mechanism 23 includes a glue water pump 231, a glue guiding pipe 232, an adjustment motor 233, an adjustment rod 234, a nozzle 235 and a glue storage tank 4; the glue water pump 231 is arranged in the glue storage tank 4, and the glue water pump 231 is connected to the nozzle 235 through the glue guiding pipe 232; the adjustment motor 233 is connected to the nozzle 235 through the adjustment rod 234; the nozzle 235 is opposite to the gluing part 2231 in position.

[0103] Among them, the glue storage tank 4 is used to hold the glue liquid, and the glue water pump 231 can provide power to enable the glue in the glue storage tank 4 to be transported to the nozzle 235 through the glue guiding pipe 232. The adjustment motor 233 can control the rotation of the nozzle 235 through the adjustment rod 234, so that the nozzle 235 can be aligned with the corresponding position on the gluing part 2231 to ensure the uniformity of glue spraying on the gluing part 2231.

[0104] As a specific implementation, as Figure 7As shown in the figure, a sandwich space is provided at the bottom of the glue storage tank 4, and a heating module is provided in the sandwich space. Among them, the heating module can be a heating resistor, an electric heating wire, etc., so as to be able to heat and keep warm the glue liquid in the glue storage tank 4, so that the temperature of the glue liquid is maintained at 50°C to 250°C, to ensure the viscosity, fluidity and other characteristics of the glue liquid, avoid the solidification of the glue liquid, and facilitate the suction of the glue water pump 231.

[0105] Among them, the notch of the glue storage tank 4 adopts a partial sealing design, and the sealed part is the part of the glue storage tank 4 that is vertically projected onto the filter material 6, so as to avoid the influence of the volatilization or temperature change of the glue liquid in the glue storage tank 4 on the filter material 6.

[0106] As a specific implementation manner, the driving mechanism 21 includes a second motor 211 and a second worm 212. The second motor 211 is connected to the second worm 212 and is used to drive the second worm 212 to rotate; the glue application roller group 22 further includes a worm gear 227, and the worm gear 227 meshes with the second worm 212 to make the glue application part 2231 rotate.

[0107] Among them, the worm gear 227 can be fixedly connected to the glue application roller 223. The second worm 212 can rotate through the drive of the second motor 211, and further make the glue application roller 223 rotate through the cooperation of the worm gear 227 and the worm, so that the glue application part 2231 can rotate with the glue application roller 223, and the movement tangent direction of the contact part between the glue application part 2231 and the filter material 6 is the same as the transmission direction of the filter material 6, so as to reduce the friction between the glue application part 2231 and the filter material 6 and ensure the stable transmission of the filter material 6.

[0108] Among them, the rotation speed of the glue application roller 223 and the transmission speed of the filter material 6 can satisfy the following formula:

[0109] x = πdy

[0110] Among them, x is the running speed of the filter material 6, with the unit of m / min; y is the rotation speed of the glue application roller 223, with the unit of revolutions / min; π is approximately 3.14; d is the diameter of the glue application roller 223, with the unit of m.

[0111] As a specific implementation manner, two glue application roller groups 22 are symmetrically arranged, and the rotation directions of the glue application parts 2231 on the two glue application rollers 223 are opposite.

[0112] In this embodiment, the two glue application roller sets 22 are respectively located on both sides of the filter material 6 in the transmission direction, so that the two sides of the filter material 6 can be glued simultaneously, improving the glue application efficiency. Among them, the glue application part 2231 of one glue application roller set 22 can rotate clockwise along with the glue application roller 223, and the glue application part 2231 of the other glue application roller set 22 can rotate counterclockwise along with the glue application roller 223, so that the movement tangent directions of the contact parts of the glue application parts 2231 of the two glue application roller sets 22 with the filter material 6 can be consistent with the transmission direction of the filter material 6, reducing the friction between the glue application part 2231 and the filter material 6 and ensuring the stable transmission of the filter material 6.

[0113] As a specific implementation manner, as Figure 3 and Figure 4 shown, the glue application assembly 2 further includes a heater 3. The heater 3 is arranged on one side of the glue application roller set 22 and is used to heat the glue application part 2231, so as to ensure the viscosity of the glue layer on the glue application part 2231, which is beneficial to the reliable adhesion of the glue liquid to the filter material 6. Among them, in order to ensure that the glue layer on the glue application part 2231 has good properties, the heater 3 can be adjusted within the range of 40°C to 200°C.

[0114] As a specific implementation manner, the edge sealing device further includes a box body 5. The box body 5 is slidably connected to the frame 1 and is used to cover the filter material 6 near the glue application assembly 2 to isolate the heat at the position of the glue application assembly 2 from being transferred to the direction of the second fabric guiding roller 12.

[0115] Among them, the heating module in the glue storage tank 4 or the heater 3 above the glue application roller set 22 will heat the glue liquid to ensure the performance of the glue liquid. However, after the edge of the filter material 6 is glued, the filter material 6 needs to continue to be transmitted in the direction of the second fabric guiding roller 12, and the glue liquid can be cooled and solidified during the transmission process before reaching the second fabric guiding roller 12. However, if the heat at the glue application assembly 2 is conducted in the direction of the second fabric guiding roller 12, it will affect the curing effect of the glue liquid at the edge of the filter material 6. For this reason, in this embodiment, by designing the box body 5 to cover the filter material 6 near the glue application assembly 2, most of the heat near the glue application assembly 2 can be isolated in the box body 5, so that the heat conducted in the direction of the second fabric guiding roller 12 can be effectively reduced, which is beneficial to the curing effect of the glue liquid at the edge of the filter material 6.

[0116] Specifically, as Figure 1As shown in the figure, the box body 5 includes a first housing 51 and a second housing 52. To facilitate the movement of the first housing 51 and the second housing 52, both the first housing 51 and the second housing 52 are slidably connected to the machine frame 1. Among them, when the first housing 51 and the second housing 52 are joined together, the filter material 6 near the glue application assembly 2 can be covered therein to achieve heat insulation; when the first housing 51 and the second housing 52 slide along the machine frame 1 in opposite directions, the first housing 51 and the second housing 52 can be opened, facilitating operations such as replenishing and replacing the glue in the glue storage tank 4.

[0117] In this embodiment, both the first housing 51 and the second housing 52 can be made of materials with high temperature resistance and heat insulation functions, so as to ensure the heat insulation effect.

[0118] Among them, in order to facilitate observing the glue application state of the glue application assembly 2 when the first housing 51 and the second housing 52 are not opened, a transparent observation window 54 can be provided on the first housing 51 or the second housing 52. It can be understood that in order to facilitate the movement of the first housing 51 and the second housing 52, handles 53 can be provided on the first housing 51 and the second housing 52.

[0119] As a specific implementation method, the distance between the side of the box body 5 close to the second fabric guide roller 12 and the center line of the second fabric guide roller 12 is greater than 1.5 m. On the one hand, it can provide enough space for the sliding of the box body 5 to avoid collision interference between the box body 5 and the second fabric guide roller 12 when the box body 5 moves; on the other hand, it can leave enough time for the glue to cool and solidify before winding, avoiding the edge of the material cloth not being firmly bonded and being wound.

[0120] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
