Description

TECHNICAL FIELD

It uses the multiple action mechanisms of fibers on particles to achieve filtration. With the development of industry, there is an urgent need for high-performance air filters, starting with high-efficiency low-resistance air filtration materials (such as nanofiber membranes and melt-blown ultrafine fiber composites).

[0040] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Reference Figure 1 A method for manufacturing a high-efficiency, low-resistance air filter material: First, the manufacturing equipment for the high-efficiency, low-resistance air filter material is inspected before startup, and the multi-port adapter 140 is connected to the metering pump to pump the molten raw material into the first meltblown box 100 and the second meltblown box 500.

[0042] Next, the melt is ejected from the first spinneret 111 and straight filaments ejected from the adjacent second spinneret 510 through the spiral-structured melt channel 600, thus forming a stable and uniform fiber web (see...). Figure 2 );

[0043] During the spinning process, the lifting block 330 is always driven to slide back and forth along the axial direction of the fourth through hole 116, thereby continuously changing the shape of the first spinneret hole 111, causing uneven protrusions on the surface of the spiral fiber that is ejected, which is equivalent to barbs that are more conducive to hooking and wrapping the fiber filaments ejected from the second spinneret hole 510.

[0044] Finally, the intertwined and firmly entangled fibers form a more stable web on the surface of the web forming machine 800, and are then conveyed to the next process.

[0045] To ensure more stable fiber web formation and prevent it from becoming loose and cloud-like, a high-efficiency, low-resistance air filter material manufacturing device is employed. This device includes a main frame 700 and a meltblown unit and a web-forming machine 800 installed within the main frame 700. The meltblown unit comprises a first meltblown box 100, multiple first shafts 200, and multiple second meltblown boxes 500. The multiple first shafts 200 are installed within the first meltblown box 100 to form multiple spiral-shaped melt channels 600. The molten material is ejected through the melt channels 600 to obtain spiral-shaped fibers, which interlock and intertwine with the straight fibers ejected from the second meltblown boxes 500. Then, the fibers are formed on the surface of the web forming machine 800 and conveyed to the next process. The spiral fibers take longer to reach the web forming machine 800 than the straight fibers, allowing for some degree of curing earlier. Therefore, the spiral fibers are the main component during the winding process, acting as a "skeleton" to support the entire fiber web. The spiral fibers and straight fibers achieve multi-layer and multi-angle winding during the forming process, forming a stable "skeleton-filler" composite structure, which greatly improves the mechanical strength and morphological stability of the fiber web and avoids the "cloud-like" looseness or transmission deformation problems that are common in traditional meltblown fiber webs.

[0046] In order to melt-blown spiral fibers, in one specific implementation, such asFigure 1 As shown, the first meltblown box 100 has a hollow internal structure. The bottom of the first meltblown box 100 has multiple first through holes 112 communicating with its interior. Each first through hole 112 has a first spiral groove 1121. The first shaft 200 has multiple shafts and is coupled to the multiple first through holes 112 respectively. By connecting the first shaft 200 with the spiral grooves in the first through holes 112, a spiral channel with a variable cross-section is formed, so that the melt naturally forms spiral fibers during extrusion. This structure is not only conducive to the self-entanglement of fibers, but also allows the fiber shape to be adjusted by changing the position of the shaft. The spiral fibers partially solidify earlier than traditional straight fibers, providing support as a "skeleton". Straight fibers shuttle and wrap around it to form a stable fiber web, preventing the fiber web from fraying or deforming during transmission.

[0047] More specifically, such as Figure 5 As shown, the outer diameter of the first shaft 200 is the same as the diameter of the first through hole 112, and a second spiral groove 210 is formed on the surface of each first shaft 200 (see...). Figure 6 The second spiral groove 210 is aligned and spliced ​​with the first spiral groove 1121 to form a filament channel 600 with a variable aperture cross-sectional shape (see...). Figure 1 The filament channel 600 has an open structure at both ends, communicating with the inside and outside of the first meltblown box 100, respectively. The opening on the outer surface of the first meltblown box 100 is designated as the first spinneret hole 111. The fibers ejected from the first spinneret hole 111 are spirally sprayed toward the web forming machine 800 (see...). Figure 3 ).

[0048] To ensure that the fibers ejected from the meltblown unit can better wind and form a stable fiber web, in one specific implementation, such as... Figure 1 and Figure 2 As shown, the second meltblown box 500 is circumferentially distributed at the bottom of the first meltblown box 100, and its top is open and connected to the inside of the first meltblown box 100. It is used for the melt to enter the second meltblown box 500 through the first meltblown box 100. Each second meltblown box 500 has a second spinneret hole 510 on both sides. The second spinneret hole 510 faces the spiral fiber filament. The fiber filament ejected from the second spinneret hole 510 is straight and wraps around the adjacent spiral fiber filament. The straight fiber filament shuttles through the spiral fiber filament and fully hooks with it, which improves the entanglement effect between the fiber filaments and makes the formed fiber web more stable.

[0049] It should be noted that each of the first shafts 200 has a second groove 220 at one end inside the first meltblown box 100 (see...). Figure 6 The second groove 220 allows the molten material to be better guided into the molten wire channel 600. To facilitate installation and make the first spinneret orifices 111 more evenly distributed, the process continues as follows... Figure 6As shown, a positioning notch 230 is provided at the other end of the first shaft 200, and a positioning protrusion 114 is provided in the open end of each first through hole 112 that communicates with the outside (see...). Figure 8 The first shaft 200 is slidably installed in the first through hole 112 and engages with the positioning protrusion 114 through the positioning notch 230, which enables the rapid installation of the first shaft 200 and improves the work efficiency of equipment assembly.

[0050] To prevent the linearly distributed first spinnerets 111 from being too widely spaced due to the influence of the first shaft 200, they are arranged in a circular pattern, such as... Figure 4 As shown, the top-view projection positions of the multiple first spinnerets 111 are not in the same vertical direction (the arrows indicate the direction of the fiber web conveying).

[0051] More specifically, such as Figure 5 As shown, the first meltblown box 100 includes a base 110, an end cap 120, and an isolation cap 130, which together form a melt cavity (see...). Figure 1 Furthermore, the separate design facilitates maintenance. The base 110 has a cylindrical structure, with a first through hole 112 opened on the circular end face of the base 110. The bottom projection of the base 110 has a first dividing line a perpendicular to the fiber mesh conveying direction (see...). Figure 4 The dividing line a divides the spinneret coverage of the first meltblown box 100 into zone I and zone II. The first through holes 112 are first arranged in a linear array (the linear direction is the dividing line a), and then arranged in a circular array (divided into 180 degrees) in zone I and zone II respectively. The number of arrays in zone I and zone II differs by one, so that the centers of the multiple first through holes 112 are misaligned, so that the multiple first spinneret holes 111 are not on the same line, which improves the uniformity of the spinneret coverage of the equipment and reduces the "weak mesh" area.

[0052] In order to ensure that the melt can fully fill the first meltblown box 100 and the second meltblown box 500, in a specific embodiment, such as Figure 6 As shown, a first groove 115 with an annular structure is formed around the top of the base 110. Multiple third through holes 1151 penetrating the outer surface of the base 110 are formed circumferentially within the first groove 115. These third through holes 1151 communicate with the interior of the second meltblown box 500, and the bottom of the second meltblown box 500 is inclined (see...). Figure 1This allows the melt to smoothly reach all the second spinneret holes 510. The isolation cover 130 is fixedly installed in the middle of the surface of the base 110 in a funnel shape. Its conical outer surface is used to guide the material flow to the first through hole 112 and the third through hole 1151. The end cover 120 is fixedly installed around the top of the base 110. The top of the end cover has a feed port. A multi-port adapter 140 is fixedly installed in the feed port. The multi-port adapter 140 works with the metering pump to ensure that the first and second meltblown boxes are fed synchronously and the pressure is stable, thus preventing uneven fiber production from the source.

[0053] More specifically, the multi-port adapter 140 uses a cross-shaped four-way connector, one end of which is connected to the feed inlet, and the other two ends are connected to the metering pump through pipes.

[0054] In actual production, the air filter materials to be manufactured by the equipment vary, thus requiring the selection of different raw materials. However, the adhesion ability of different raw materials after spinning in a molten state differs. To enable the equipment to manufacture different fiber webs and ensure their stability, in a specific implementation plan, such as... Figure 1 As shown, the base 110 has a fourth through hole 116 in the middle. The fourth through hole 116 is equipped with a transmission mechanism 300 for simultaneously changing the shape of the diameter of all the first spinnerets 111. By continuously changing the cross-sectional shape of the spiral fiber during the spinning process, protrusions of different sizes (similar to barbs) are formed on its surface, which significantly enhances the mechanical connection between fibers and improves the peeling strength and stability of the fiber web.

[0055] More specifically, such as Figure 1 and Figure 9 As shown, the transmission mechanism 300 includes a lifting block 330, the outer diameter of which is the same as the inner diameter of the fourth through hole 116. The lifting block 330 can be driven to slide back and forth in the fourth through hole 116. A connecting block 340 is fixedly installed at the bottom of the lifting block 330. The bottom of the base 110 has a groove adapted to the connecting block 340. Multiple connecting rods 350 are circumferentially installed around the connecting block 340. Each connecting rod 350 passes through multiple first shafts 200 and the outer surface of the base 110. The base 110 has multiple second through holes 113 with a waist-groove structure (see...) circumferentially. Figure 7 and Figure 8 ), which is used to avoid the reciprocating movement of the connecting rod 350, in one specific embodiment, such as Figure 9 As shown, the connecting rod 350 is threadedly connected to the adapter block 340. One end of the rod has an external thread 351, and the other end has a marking for partition positioning, which facilitates quick location and replacement of the first shaft 200 during maintenance.

[0056] In one specific implementation, continue as follows Figure 9As shown, the transmission mechanism 300 also includes a second shaft 310 and a reciprocating lead screw 320. One end of the reciprocating lead screw 320 is threadedly connected to the lifting block 330, and the other end is fixedly connected to the end of the second shaft 310. One end of the second shaft 310 passes through the isolation cover 130 and is rotatably connected to it. A servo motor 900 is fixedly installed on the top of the main frame 700. The output end of the servo motor 900 is fixedly installed at the rotation center of one end of the second shaft 310.

[0057] It is important to note that at this time, one end of the second shaft 310 passes through and is rotatably connected to the multi-port adapter 140. The connection is properly sealed. The outer diameter of the second shaft 310 is smaller than the inner diameter of the multi-port adapter 140. The second shaft 310 is driven to rotate by the servo motor 900, which in turn drives the reciprocating screw 320 to rotate. The reciprocating screw 320 drives the lifting block 330 to slide back and forth in the fourth through hole 116. In turn, the multiple connecting rods 350 drive all the first shafts 200 to slide in the first through hole 112, thereby changing the cross-sectional shape of the filament channel 600, so that the first spinneret 111 ejects spiral fibers that are easier to hook into other fibers.

[0058] Considering that the melt dissipates heat quickly at the inner wall of the first meltblown box 100, it is prone to premature solidification, affecting the smoothness of the spinneret. In a specific solution, such as Figure 10 As shown, a stirring assembly 400 is fixedly sleeved on the surface of the second shaft 310. The stirring assembly 400 not only prevents the raw material from solidifying, but also promotes the uniform entry of the molten material into each spinneret hole through continuous stirring, ensuring that the fiber linear density is consistent.

[0059] More specifically, the stirring assembly 400 includes a stirring frame 410, a scraper 420, and a protrusion 430, the protrusion 430 being fixedly connected to the second shaft 310 (see...). Figure 1 The stirring frame 410 has a triangular structure with a hollow structure in the middle to increase the stability of the stirring process. One end of the stirring frame 410 is fixedly connected to the protrusion 430, and the other end is fixedly connected to the scraper 420. The scraper 420 abuts against the inner wall of the first meltblown box 100. The surface of the scraper 420 has two symmetrically opened arc-shaped material grooves 421.

[0060] When the second shaft 310 rotates, it drives the stirring frame 410 to stir in the first meltblown box 100. In particular, the melt on the inner wall is evenly mixed with the melt in the middle under the scraper of the scraper 420, avoiding local solidification and improving the utilization rate of the equipment.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
