Description

Technical Field

[0001] This utility model relates to the field of filter material processing, and in particular to an air filter material composite device. Background Technology

[0002] Air filter media is the core component of filters, removing particulate matter from the air through mechanisms such as physical interception and electrostatic adsorption. It is widely used in automotive, medical, and industrial purification fields. Filter media composite devices are used to combine materials with different properties to create composite materials with specific filtration performance.

[0003] In traditional technology, the composite device uses rigid rollers to extrude and composite sheet filter media. The surface of the rigid rollers cannot effectively adapt to the thickness fluctuations of the filter media, which can easily lead to stress concentration at the edges, resulting in an increased interlayer bubble rate, affecting filtration efficiency and the interlayer sealing of the air filter media, and resulting in poor composite effect. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air filter material composite device capable of adaptive full-scale composite, with uniform and reliable composite effect, and the resulting composite filter material sheet has reliable sealing.

[0005] An air filter material composite device according to an embodiment of the present invention includes:

[0006] The composite molding assembly includes two sets of first elastic pressing molds and two rigid rollers. The two rigid rollers are rotatably connected between the two sets of first elastic pressing molds. The first elastic pressing molds are used to make the two rigid rollers move closer to each other. The circumferential surface of each rigid roller is covered with an elastic buffer sleeve. The outer surface of each elastic buffer sleeve is provided with several spaced elastic pressure flaps. The two rigid rollers are symmetrical about the composite surface.

[0007] The filter media supply assembly includes a surface unwinding roller, a sandwich unwinding roller, a bottom unwinding roller, and surface guide rollers, sandwich guide rollers, and bottom guide rollers, all located on the same side of the rigid roller shaft. The surface unwinding roller is located on the side of the surface guide roller away from the rigid roller shaft, the sandwich unwinding roller is located on the side of the sandwich guide roller away from the rigid roller shaft, and the bottom unwinding roller is located on the side of the bottom guide roller close to the rigid roller shaft. The surface guide roller is located above the composite surface, and the bottom unwinding roller and the bottom guide roller are both located below the composite surface. A surface adhesive brushing roller and a surface adhesive storage box are sequentially arranged below the surface guide roller, and a bottom adhesive brushing roller and a bottom adhesive storage box are sequentially arranged below the bottom guide roller.

[0008] In this embodiment, the elastic pressure flaps are distributed along a circumferential trajectory around the rigid roller shaft, and the interval between each two adjacent elastic pressure flaps is equal.

[0009] In this embodiment, the interval between each two adjacent elastic pressure flaps is hourglass-shaped.

[0010] In this embodiment, the first elastic pressure-blocking module includes a first slide block, a first fixed block, a first lifting block, and a first elastic member. The first fixed block is connected to the bottom of the first slide block, the first lifting block is slidably connected to the first slide block, and the two ends of the first elastic member are respectively connected to the first slide block and the first lifting block, so that the first lifting block forms a tendency to move closer to the first fixed block. Two rigid roller shafts are respectively rotatably connected to the first fixed block and the first lifting block.

[0011] In this embodiment, the composite molding assembly further includes a heating module located on the side of the hard roller shaft opposite to the surface guide roller.

[0012] In this embodiment, the heating module includes a heat insulation box, an arc-shaped heat-conducting plate, and a heater. The arc-shaped heat-conducting plate is connected to the opening of the heat insulation box, and the heater is located inside the heat insulation box. The arc-shaped heat-conducting plate intersects with the composite surface, and the heater is located on the side of the arc-shaped heat-conducting plate away from the composite surface.

[0013] In this embodiment, there are two sets of heating modules, which are located on the upper and lower sides of the composite surface, respectively.

[0014] In this embodiment, the composite molding assembly also includes two leveling rollers. The leveling rollers are located on the side of the heating module away from the hard roller shaft. A set of second elastic pressure modules is rotatably connected to both ends of the leveling rollers. The second elastic pressure modules are used to make the two leveling rollers move closer to each other.

[0015] In this embodiment, the second elastic pressure module includes a second slide, a second fixed block, a second lifting block, and a second elastic member. The second fixed block is connected to the bottom of the second slide, the second lifting block is slidably connected to the second slide, and the two ends of the second elastic member are respectively connected to the second slide and the second lifting block, so that the second lifting block tends to move closer to the second fixed block. Two leveling pressure rollers are respectively rotatably connected to the second fixed block and the second lifting block.

[0016] The embodiments of this utility model have at least the following beneficial effects:

[0017] By using a split-spaced elastic buffer sleeve to form elastic pressure flaps, dynamic pressure balance can be achieved. When two rigid rollers approach each other to extrude and laminate the air filter material, multiple discrete elastic pressure flaps can achieve regional adaptive extrusion lamination. The elastic pressure flaps adapt to the thickness and shape of the filter material in the corresponding area through independent deformation. The lamination extrusion pressure distribution is flexible and balanced, the lamination effect is comprehensive and reliable, and the lamination sealing performance is good, which can effectively ensure the filtration efficiency of the produced filter material composite sheet. The bottom layer of filter material is coated from bottom to top by the bottom brushing roller, and the bottom layer guide roller flips the bottom layer of filter material between the bottom unwinding roller and the rigid roller on the same side. This allows the brushed surface of the bottom layer of filter material to be flipped upward to adapt to the lamination of the three layers of filter material. The brushed surfaces of each filter material are concentrated in the center of the lamination interface, which can effectively improve the firmness and tightness of the lamination. Furthermore, the brushing roller and glue storage box, which brush glue from bottom to top, can not only effectively ensure the uniformity of the glue application and the uniform and reliable lamination effect, but also effectively avoid glue dripping and waste and equipment contamination, which can effectively save glue costs and maintenance costs.

[0032] Air filter media is the core component of filters, removing particulate matter from the air through mechanisms such as physical interception and electrostatic adsorption. It is widely used in automotive, medical, and industrial purification fields. Filter media composite devices are used to combine materials with different properties to create composite materials with specific filtration performance.

[0033] In traditional technologies, composite devices use rigid rollers to extrude and laminate sheet filter media. The surface of these rigid rollers cannot effectively adapt to variations in filter media thickness, easily leading to stress concentration at the edges. This increases the interlayer bubble rate, affecting filtration efficiency and the interlayer sealing of the air filter media, resulting in poor lamination. Adhesives are typically used to bond the filter media layers. Current technologies usually employ a glue-applying roller with a glue-applying box to apply adhesive. The roller rotates to pick up adhesive from the box and coat the bottom surface of the filter media. When multiple layers of filter media need to be laminated, the top surface can only be coated by dripping adhesive from top to bottom. This method results in uneven coating, prone to over-coating, and the adhesive is easily dripped and contaminated, making the device difficult to maintain.

[0034] The following is for reference only. Figure 1 To be continued Figure 6 The air filter material composite device described in this utility model is capable of adaptive full composite, with uniform and reliable composite effect, and the composite filter material sheet produced by the composite is reliably sealed.

[0035] Reference Figures 1 to 6 An air filter material composite device according to an embodiment of the present invention includes:

[0036] The composite molding assembly 100 includes two sets of first elastic pressing molds 110 and two vertically distributed rigid rollers 120. The two rigid rollers 120 are parallel to each other and rotatably connected between the two sets of first elastic pressing molds 110. The first elastic pressing molds 110 are used to cause the two rigid rollers 120 to move closer to each other. One of the rigid rollers 120 is connected to a bonding motor. The circumferential surface of each rigid roller 120 is covered with an elastic buffer sleeve 121. The outer surface of each elastic buffer sleeve 121 is provided with a plurality of spaced elastic pressure flaps 122. The elastic pressure flap 122 and the elastic buffer sleeve 121 are integrally formed. The elastic pressure flap 122 forms an arc transition structure, which can suppress stress cracking and thus extend service life. Through the elastic extrusion structure of multiple elastic pressure flaps 122, when the air filter material is laminated, the elastic pressure flap 122 can achieve adaptive full fit of each layer of the air filter material through its elastic deformation capability and sufficient spacing space. The composite molding component 100 is provided with a composite surface, and the two hard rollers 120 are symmetrical about the composite surface. Preferably, the composite surface is parallel to the horizontal plane.

[0037] The filter media supply assembly 200 includes a surface unwinding roller 210, a sandwich unwinding roller 220, a bottom unwinding roller 230, a surface guide roller 240, a sandwich guide roller 250, and a bottom guide roller 260. With the horizontal direction as a reference, the surface guide roller 240, sandwich guide roller 250, and bottom guide roller 260 are all located on one side of the rigid roller shaft 120. The surface unwinding roller 210 is located on the side of the surface guide roller 240 away from the rigid roller shaft 120, and the sandwich unwinding roller 220 is located on the side of the sandwich guide roller 250 away from the rigid roller shaft 120. The sandwich guide roller 250 is used to deliver the sandwich filter media output from the sandwich unwinding roller 220 to the rigid roller shaft 120. 0. The bottom unwinding roller 230 is located on the side of the bottom guide roller 260 closest to the hard roller shaft 120, that is, the hard roller shaft 120 and the bottom unwinding roller 230 are located on the same side of the bottom guide roller 260. With a direction perpendicular to the horizontal plane as a reference, the surface guide roller 240 is located above the composite surface. The surface guide roller 240 is used to feed the surface filter material output from the surface unwinding roller 210 to the hard roller shaft 120 after passing through the bottom of the surface guide roller 240. The bottom unwinding roller 230 and the bottom guide roller 260 are both located below the composite surface. The bottom guide roller 260 is used to feed the bottom filter material output from the bottom unwinding roller 230 from the bottom of the bottom guide roller 260. The bottom layer filter material, including the bottom layer and side layers, is fed to the rigid roller shaft 120 so that the bottom layer filter material output from the bottom layer unwinding roller 230 rotates more than 90 degrees after passing through the bottom layer guide roller 260 and then advances towards the rigid roller shaft 120. The interlayer guide roller 250 is located between the surface layer guide roller 240 and the bottom layer guide roller 260. Below the surface layer guide roller 240, there are parallel surface layer adhesive rollers 270, which are used to apply adhesive to the bottom surface of the surface layer filter material wound on the surface layer guide roller 240. Below the surface layer adhesive roller 270, there is a surface layer adhesive storage box 271, which is used to provide adhesive for the surface layer adhesive roller 270. Below the bottom layer guide roller 260, there is a... There are parallel bottom glue-applying rollers 280. The bottom glue-applying rollers 280 are used to apply glue to the bottom surface of the bottom filter material wound on the bottom guide roller 260. After the bottom surface of the bottom filter material is rotated by more than 90 degrees, the glue layer is flipped to face upward. The layout design of the bottom glue-applying rollers 280 has few restrictions, which can effectively reduce the design difficulty and simplify the device structure. The bottom glue-applying rollers 280 are provided with a bottom glue storage box 281 below them. The bottom glue storage box 281 is used to provide adhesive for the bottom glue-applying rollers 280. The surface unwinding roller 210 is connected to the surface motor, the interlayer unwinding shaft is connected to the interlayer motor, and the bottom unwinding shaft is connected to the bottom motor.

[0038] When applying, refer to Figure 6As shown, the surface unwinding roller 210 is used to unwind the surface filter material. After the surface filter material passes around the surface guide roller 240, it reaches between the two rigid roller shafts 120. The surface filter material advances along the surface trajectory between the surface unwinding roller 210 and the rigid roller shafts 120. The surface guide roller 240 is located on the surface trajectory, and the surface adhesive roller 270 is located below the surface trajectory. The interlayer unwinding roller 220 is used to unwind the interlayer filter material. The interlayer filter material passes around the interlayer guide roller 250. The filter media then reaches the space between the two rigid rollers 120. The sandwiched filter media advances along a sandwich track between the sandwich unwinding roller 220 and the rigid roller 120. The sandwich guide roller 250 is positioned above or below the sandwich track. The bottom unwinding roller 230 is used to unwind the bottom filter media. After passing the bottom guide roller 260, the bottom filter media reaches the space between the two rigid rollers 120. The bottom filter media advances along a bottom track between the bottom unwinding roller 230 and the rigid roller 120. The bottom track starts from... The bottom guide roller 260 passes around the side of the rigid roller shaft 120 from bottom to top, and the bottom adhesive roller 280 is located below the bottom track. The surface filter material, the interlayer filter material, and the bottom filter material pass between the two rigid roller shafts 120. Driven by the first elastic pressure module 110, the two rigid roller shafts 120 form a tendency to move closer to each other, so that the two elastic buffer sleeves 121 clamp the surface filter material, the interlayer filter material, and the bottom filter material between them. The elastic buffer sleeve 121 specifically contacts the filter material through the elastic pressure flaps 122 on its surface, which can achieve a tight extrusion composite effect through adaptive deformation. Especially when the interlayer filter material is set as a metal mesh structure, the elastic pressure flap 122 structure can effectively adapt to this kind of filter material with obvious concavity and convexity to achieve extrusion composite. The surface filter material can be set as glass fiber filter material, and the bottom filter material can be set as activated carbon filter material. Finally, the filter material composite sheet is obtained by extrusion composite.

[0039] The air filter material composite device also includes a composite molding assembly 100, a surface material supply assembly, a sandwich material supply assembly, and a bottom material supply assembly for mounting the composite molding assembly 100.

[0040] By setting elastic buffer sleeves 121 at separate intervals to form elastic pressure flaps 122, dynamic pressure balance can be achieved. When two rigid rollers 120 approach each other to extrude and laminate the air filter material, multiple discrete elastic pressure flaps 122 replace the whole-surface extrusion in traditional technology, enabling regional adaptive extrusion lamination. The elastic pressure flaps 122 adapt to the thickness and shape of the filter material in the corresponding area through independent deformation, resulting in flexible and balanced distribution of lamination pressure, comprehensive and reliable lamination effect, and good lamination sealing performance. This effectively reduces the bubble rate and edge delamination rate of the resulting filter material composite sheet, effectively ensuring the filtration efficiency of the resulting filter material composite sheet. The bottom layer filter material is coated from bottom to top by the bottom layer adhesive roller 280. The bottom guide roller 260 flips the bottom filter material between the bottom unwinding roller 230 and the rigid roller shaft 120 on the same side, allowing the glue-applied surface of the bottom filter material to face upwards to accommodate the composite of three layers of filter material. The surface glue-applied roller applies glue to the bottom surface of the surface filter material, and the glue-applied surfaces of each filter material are concentrated at the center of the composite interface, which can effectively improve the strength and tightness of the composite. The resulting filter material composite sheet has high peel strength. Furthermore, the glue-applied roller and glue storage box, which apply glue from bottom to top, can not only effectively ensure the uniformity of glue application and the uniform and reliable composite effect, but also effectively avoid glue dripping and waste and contamination of the equipment. This can effectively save on glue costs and maintenance costs. The overall structure is simple and reliable, the layout design is convenient, and the space utilization rate is high.

[0041] It is understood that the elastic pressure flaps 122 on the outer surface of the same elastic buffer sleeve 121 are distributed along a circumferential trajectory around the hard roller shaft 120, and the interval between each two adjacent elastic pressure flaps 122 is equal. That is, the elastic pressure flaps 122 on the outer surface of the same elastic buffer sleeve 121 are distributed along a circumferential trajectory with the axis of the hard roller shaft 120 as the circle, and the interval between each two adjacent elastic pressure flaps 122 is equal.

[0042] It is understandable that, along the cross section perpendicular to the rigid roller shaft 120, the interval between each two adjacent elastic pressure plates 122 is hourglass-shaped, that is, the radial width of the elastic pressure plate 122 is narrow at both ends and wide in the middle, which can simultaneously obtain the extrusion composite effect of stable support and reliable deformation.

[0043] Specifically, the central angle formed by the center lines of every two adjacent elastic pressure flaps 122 on the same elastic buffer sleeve 121 within the cross-section of the hard roller shaft 120 is θ, where 5°≤θ≤10°. The cross-sectional shape of the elastic pressure flap 122 is narrow at both ends and wide in the middle. When projected along the radial direction of the hard roller shaft 120, the arc length of the projection of the elastic pressure flap 122 onto the circumference of the hard roller shaft 120 is L1, and the circumference of the hard roller shaft 120 is L2, where L1=kL2, and 0.65≤k≤0.98. Through the combination of low coverage and high elastic deformation, both pressure continuity and adaptive compensation capability are ensured, resulting in reliable extrusion composite molding effect.

[0044] It is understood that the first elastic compression module 110 includes a first slide block 111, a first fixed block 112, a first lifting block 113, and a first elastic element 114. The first fixed block 112 is connected to the bottom of the first slide block 111, and the first lifting block 113 is slidably connected to the first slide block 111 so that the first lifting block 113 can rise and fall relative to the first slide block 111. The first slide block 111 is equipped with a linear guide rail to effectively limit the position of the first lifting block 113. The first lifting block 113 is located above the first fixed block 112. The two ends of an elastic element 114 are respectively connected to the first slide block 111 and the first lifting block 113, so that the first lifting block 113 tends to move closer to the first fixed block 112. Preferably, the first elastic element 114 is a spring. Two rigid roller shafts 120 are respectively rotatably connected to the first fixed block 112 and the first lifting block 113. That is, the two ends of one rigid roller shaft 120 are respectively rotatably connected to the two first fixed blocks 112, and the two ends of the other rigid roller shaft 120 are respectively rotatably connected to the two first lifting blocks 113.

[0045] Specifically, the first lifting block 113 is connected to a height adjustment mechanism. By adjusting the height of the first lifting block 113, the distance between the two hard roller shafts 120 can be easily adjusted when changing lines, thereby reducing the difficulty of picking up and putting down materials.

[0046] It is understood that the composite molding assembly 100 also includes a heating module 130, which is located on the side of the rigid roller shaft 120 away from the surface guide roller 240. The heating module 130 is used to accelerate the curing of each layer of filter material after roll pressing, which can effectively improve the composite molding efficiency.

[0047] It is understood that the heating module 130 includes a heat insulation box 131, an arc-shaped heat-conducting plate 132, and a heater 133. The arc-shaped heat-conducting plate 132 is connected to the opening of the heat insulation box 131, and the heater 133 is located inside the heat insulation box 131. The arc-shaped heat-conducting plate 132 intersects with the composite surface to increase the contact area between the filter material composite sheet and the arc-shaped heat-conducting plate 132. In the same group of heating modules 130, the heater 133 is located on the side of the arc-shaped heat-conducting plate 132 away from the composite surface.

[0048] The heater 133 has its heating surface directly facing the arc-shaped heat-conducting plate 132. The heater 133 heats the arc-shaped heat-conducting plate 132, and through the arc-shaped heat-conducting plate 132 in conjunction with the insulation box 131, it effectively controls most of the heat energy from being transferred to the surface of the filter material via the arc-shaped heat-conducting plate 132, resulting in high safety and high energy utilization. The heater 133 can be an infrared heater. The insulation box 131 has an aerogel interlayer or a heat-insulating cotton layer, which provides good heat insulation protection and effectively reduces heat loss.

[0049] It is understood that there are two sets of heating modules 130. Two sets of heating modules 130 are arranged sequentially along the forward direction of the filter material composite sheet, and the two sets of heating modules 130 are located on the upper and lower sides of the composite surface, respectively. They can heat the upper and lower surfaces of the filter material composite sheet, which can effectively improve the uniformity of heating of the filter material composite sheet, thereby improving the structural stability of the filter material composite sheet formed by the composite.

[0050] It is understood that the composite molding assembly 100 also includes two leveling rollers 140 distributed vertically. Both leveling rollers 140 are located on the side of the heating module 130 away from the hard roller shaft 120. A set of second elastic pressure modules 150 is rotatably connected to the opposite ends of the two leveling rollers 140. The second elastic pressure modules 150 are used to make the two leveling rollers 140 move closer to each other.

[0051] It should be noted that the leveling roller 140 is a metal roller with high thermal conductivity, such as a copper-aluminum alloy roller. The two leveling rollers 140 can not only press and level the heated filter material composite sheet to improve the adhesion and flatness of the filter material composite sheet, but also cool the filter material composite sheet by the metal roller with high thermal conductivity, which can effectively release the internal stress of the filter material composite sheet and effectively improve the structural stability of the final filter material composite sheet.

[0052] It is understood that the second elastic compression module 150 includes a second slide 151, a second fixed block 152, a second lifting block 153, and a second elastic element 154. The second fixed block 152 is connected to the bottom of the second slide 151, and the second lifting block 153 is slidably connected to the second slide 151 so that the second lifting block 153 can rise and fall relative to the second slide 151. The second slide 151 is equipped with a linear guide rail to effectively limit the position of the second lifting block 153. The second lifting block 153 is located above the second fixed block 152. The two ends of the two elastic elements 154 are respectively connected to the second slide block 151 and the second lifting block 153, so that the second lifting block 153 forms a tendency to move closer to the second fixed block 152. Preferably, the second elastic element 154 is a spring. The two leveling pressure rollers 140 are respectively rotatably connected to the second fixed block 152 and the second lifting block 153. That is, the two ends of one leveling pressure roller 140 are respectively rotatably connected to the two second fixed blocks 152, and the two ends of the other leveling pressure roller 140 are respectively rotatably connected to the two second lifting blocks 153.

[0053] Specifically, the second lifting block 153 is connected to a height adjustment mechanism. By adjusting the height of the second lifting block 153, the distance between the two leveling rollers 140 can be easily adjusted when changing lines, thereby reducing the difficulty of material handling operations.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
