Abstract
Description
Technical Field
[0001] This invention relates to the field of meltblown material processing equipment, specifically to a special meltblown material processing equipment and process for twin spinning. Background Technology
[0002] Meltblown fabrication is a nonwoven fabric processing technology that stretches polymer melt into ultrafine fibers through high-speed hot air and directly forms a web on a receiving device. In the twin-spinning meltblown process, a composite die extruder simultaneously extrudes two polymer melts of different components, which are then stretched, cooled, and deposited onto the surface of an annular roller under the action of high-temperature, high-speed airflow to form a fiber web. In this process, uniform fiber deposition, rapid cooling and setting, and the stability of the web quality are key factors determining the performance of the final product.
[0003] However, because the fibers are at a high temperature when they are ejected, and the annular rollers usually use internal cooling water circulation to cool them down, the surface temperature of the rollers is significantly lower than the dew point of the surrounding environment. Water vapor in the air is very easy to condense on the surface of the rollers. If this moisture adheres to the surface of the fibers or the web, it will not only reduce the insulation, strength and bulk of the fibers, but may also cause local adhesion, mold or spot defects in the web. Summary of the Invention
[0004] The purpose of this invention is to provide a special meltblown material processing equipment and process for twin spinning, so as to solve the problems mentioned in the background art.

The dehumidification mechanism includes an annular roller installed inside the mounting frame. The annular roller has several annular grooves, and several circular holes are provided on the inner walls of the annular grooves. The annular roller also has several fan-shaped grooves, which are all connected to the annular grooves. Several strip grooves are provided on the inner walls of the annular grooves.

The cooling mechanism is used to continuously cool the annular drum. A blower mechanism is mounted on a rotating shaft. The blower mechanism includes an isosceles triangular block mounted on the rotating shaft. An annular hollow block is provided on the back of the mounting frame. A rectangular jet box is provided on the mounting frame. The blower mechanism is used for secondary cooling of the fiber web.
[0006] Furthermore, the dehumidification mechanism also includes a hollow support frame and a fixed support frame fixedly installed on the annular drum. The hollow support frame and the fixed support frame respectively pass through the rotating mounting frame. An exhaust fan is fixedly installed on the back of the mounting frame. Several annular grooves are opened inside the annular drum. The exhaust fan communicates with the hollow support frame and the several annular grooves.
[0007] Furthermore, several circular holes are respectively opened on the inner walls of several annular grooves, several fan-shaped grooves are respectively opened in the inner walls of several annular rollers, several strip-shaped grooves are respectively opened on the inner walls of several fan-shaped grooves, and several fan-shaped grooves, several strip-shaped grooves, several annular grooves and several circular holes are all interconnected.
[0008] Furthermore, a water tank is fixedly installed inside the mounting frame, the water tank being located directly below the annular roller, and a composite die head ejector is fixedly installed on the top inner wall of the mounting frame.
[0009] Furthermore, the cooling mechanism also includes a threaded cavity formed inside the annular drum. Annular boxes are rotatably mounted on the front and back sides of the annular drum, and both annular boxes are connected to the threaded cavity. A water inlet pipe is fixedly mounted on the front side of the corresponding annular box. A water pump is fixedly mounted on the front side of the mounting bracket. The water pump is connected to the water tank, and the end of the water inlet pipe is connected to the water pump.
[0010] Furthermore, a water outlet pipe is fixedly installed on the back of the corresponding annular box, a nozzle is fixedly installed at the end of the water outlet pipe, an inclined filter plate is fixedly installed inside the water tank, a take-up roller is fixedly sleeved on the rotating shaft, a drive motor is fixedly installed on the front of the mounting frame, and the output end of the drive motor is fixedly connected to the rotating shaft.
[0011] Furthermore, a guide roller is rotatably installed inside the mounting frame, the fiber web passes through the annular roller and the guide roller and is wound around the take-up roller, and pulleys are fixedly sleeved on the fixed support frame and the rotating shaft, and synchronous belts are sleeved on the two pulleys.
[0012] Furthermore, the blower mechanism also includes an isosceles triangular block fixedly sleeved on the rotating shaft. The isosceles triangular block has two ends. An annular hollow block is fixedly installed on the back of the mounting bracket. Several rectangular boxes are fixedly installed on the annular hollow block. Each of the several rectangular boxes has an L-shaped groove. The several L-shaped grooves are all connected to the annular hollow block. Limiting springs are fixedly installed on the inner walls of the several rectangular boxes on the sides that are far apart from each other. Rectangular plates are fixedly installed on the ends of the several limiting springs that are close to each other.
[0013] Furthermore, strip-shaped limiting plates are fixedly installed on the adjacent sides of several rectangular plates, and the adjacent ends of several strip-shaped limiting plates slide out of several rectangular boxes. Strip-shaped air inlet slots are opened on the left and right sides of several rectangular boxes. A rectangular jet box is fixedly installed on the top of the mounting frame, and an L-shaped air supply pipe is fixedly installed on the left side of the rectangular jet box. The L-shaped air supply pipe communicates with the annular hollow block.
[0014] This invention also discloses a processing technology for meltblown materials specifically for twin spinning, the steps of which are as follows: S1, Dehumidification: When water condenses into water droplets, it will pass through the strip groove and enter the fan groove due to gravity and the rotation of the annular roller and be sucked out by the exhaust fan. While the strip groove and several circular holes are simultaneously exhausting air, the movement of airflow around the annular roller will be accelerated, further reducing the condensation of water droplets and the drying of water. This prevents condensate or cooling water from seeping into the fiber web and leaving mineral residues after evaporation, which would affect the quality of the fiber web. S2, Water cooling: The water pump draws cooling water from the water tank and injects it into the threaded cavity through the inlet pipe and the annular box. When the cooling water passes through the threaded cavity, it will uniformly cool the outer wall of the annular roller, thereby indirectly cooling the fiber web and preventing the fiber web from deforming due to uneven cooling. S3, Air Cooling: The rectangular plate compresses the air inside the rectangular box. The compressed air enters the annular hollow block through the L-shaped groove. The air is then injected into the L-shaped air supply pipe from the annular hollow block, and then into the rectangular jet box through the L-shaped air supply pipe. The gas ejected from the rectangular jet box will perform secondary cooling on the fiber web, which not only reduces the warping of the fiber web caused by the difference in shrinkage rate, but also improves the uniformity of the fiber web. S4, Air Replenishment: Under normal conditions, the rectangular plate will open the strip air inlet slot to communicate with the outside. At this time, since the other two rectangular boxes are connected to the outside, the rectangular plate will replenish air through the annular hollow block and the strip air inlet slot on the other rectangular box when it resets, thereby ensuring that the rectangular box can quickly replenish air to prepare for the next blowing.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a special meltblown material processing device for twin spinning. During use, when the composite die head feeder spins yarn onto the annular roller, an exhaust fan is activated. The exhaust fan generates suction force through a hollow support frame, annular groove, fan-shaped groove, and several circular holes. Because the spun yarn drifts with the hot air, the suction force guides the yarn onto the annular roller, providing a force that ensures the yarn falls stably onto the roller. Since the spun yarn is at a high temperature, it is cooled by the cooling mechanism upon landing on the annular roller. Moisture condenses on the surface of the roller, which can affect the quality of the yarn. As the annular roller rotates, the moisture moves and drips into the water tank under the influence of gravity for collection. If the moisture condenses into droplets, it will pass through the strip groove and enter the fan groove due to gravity and the rotation of the annular roller, where it will be sucked out by the fan. Simultaneous suction in the strip groove and several circular holes will accelerate the airflow around the annular roller, further reducing the condensation of water droplets and the drying of moisture. This prevents condensate or cooling water from seeping into the fiber web and leaving mineral residues after evaporation, which would affect the quality of the fiber web. 2. This invention provides a special meltblown material processing equipment for twin spinning. When the device is working, the drive motor and water pump are started. The drive motor drives the rotating shaft to rotate, the rotating shaft drives the pulley to rotate, and the pulley and synchronous belt drive the fixed support frame to rotate. The fixed support frame rotates synchronously with the annular drum to ensure stable cooling and collection of the fiber web after spraying. The water pump draws cooling water from the water tank and injects it into the threaded cavity through the inlet pipe and the annular box. When the cooling water passes through the threaded cavity, it will uniformly cool the outer wall of the annular drum, thereby indirectly cooling the fiber web. This can effectively prevent the fiber web from deforming due to uneven cooling. Correspondingly, the cooling water sprayed from the annular box and the outlet pipe on the front of the annular drum will re-enter the water tank through the nozzle. Because the nozzle opening is narrow, the water flow will increase the contact area with the air when spraying, further cooling the cooled water and ensuring the temperature of the cooling water is stable for continuous use. 3. The present invention provides a special meltblown material processing equipment for twin spinning. When the rotating shaft rotates, it also drives the isosceles triangular block to rotate. The two ends of the isosceles triangular block will contact two symmetrical strip-shaped limiting plates. Under the action of the inclined surface of the isosceles triangular block, the two strip-shaped limiting plates will move away synchronously. The strip-shaped limiting plates will drive the rectangular plate to move, and the corresponding limiting spring will undergo compression deformation. The rectangular plate will squeeze the air in the rectangular box. The squeezed air will enter the annular hollow block from the L-shaped groove. The air will be injected into the L-shaped air supply pipe from the annular hollow block, and then input into the rectangular air jet box from the L-shaped air supply pipe. The gas ejected from the rectangular air jet box will perform secondary cooling on the fiber web. This can not only reduce the warping of the fiber web caused by the difference in shrinkage rate and improve the uniformity of the fiber web, but also promote the formation of a more uniform microporous structure of the fibers and improve the fiber web's interception rate of particulate matter. 4. The present invention provides a special meltblown material processing device for twin spinning. After the isosceles triangular block leaves the corresponding two strip-shaped limiting plates, the strip-shaped limiting plates and the rectangular plate will reset under the elastic force of the limiting spring. Under the normal state of the limiting spring, the rectangular plate will open the strip-shaped air inlet groove to communicate with the outside. At this time, since the other two rectangular boxes are connected to the outside, the reset of the rectangular plate will replenish air through the annular hollow block and the strip-shaped air inlet groove on the other rectangular box, thereby ensuring that the rectangular box can quickly replenish air to prepare for the next blowing. The corresponding isosceles triangular block will immediately connect with the next adjacent strip-shaped limiting plate after leaving the corresponding strip-shaped limiting plate, thereby ensuring that the rectangular jet box can continuously blow air and enhance the stability of secondary cooling.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1 - Figure 8 As shown, the present invention is a special meltblown material processing equipment for twin spinning, including a mounting frame 1 and a fiber web 211, and further including: The dehumidification mechanism is installed inside the mounting frame 1. The dehumidification mechanism includes an annular roller 101 installed inside the mounting frame 1. The annular roller 101 has several annular grooves 105. Several circular holes 106 are provided on the inner walls of the several annular grooves 105. Several fan-shaped grooves 107 are provided inside the annular roller 101. The several fan-shaped grooves 107 are all connected to the several annular grooves 105. Several strip grooves 108 are provided on the inner walls of the several annular grooves 105. The dehumidification mechanism is used to remove the moisture condensed on the annular roller 101. The cooling mechanism is set inside the annular drum 101. The cooling mechanism includes a threaded cavity 2 set inside the annular drum 101. The front and back of the annular drum 101 are respectively provided with annular boxes 201. The water tank 109 is provided with inclined filter plates 206. A rotating shaft 207 is rotatably mounted through the mounting frame 1. The cooling mechanism is used to continuously cool the annular drum 101. The blower mechanism is mounted on the rotating shaft 207. The blower mechanism includes an isosceles triangular block 3 mounted on the rotating shaft 207. An annular hollow block 301 is provided on the back of the mounting frame 1. A rectangular jet box 307 is provided on the mounting frame 1. The blower mechanism is used to perform secondary cooling on the fiber web 211.
[0020] like Figure 2 , Figure 3 ,and Figure 4 As shown, the dehumidification mechanism also includes a hollow support frame 102 and a fixed support frame 103 fixedly installed on the annular drum 101. The hollow support frame 102 and the fixed support frame 103 respectively pass through the rotating mounting frame 1. An exhaust fan 104 is fixedly installed on the back of the mounting frame 1. Several annular grooves 105 are opened in the annular drum 101. The exhaust fan 104 communicates with the hollow support frame 102 and the several annular grooves 105.
[0021] When the composite die head feeder 110 spins silk onto the annular roller 101, the exhaust fan 104 is started. The exhaust fan 104 generates suction force through the hollow support frame 102, the annular groove 105, the fan-shaped groove 107 and several circular holes 106.
[0022] like Figure 7 As shown, several annular grooves 105 have several circular holes 106 on their inner walls, several annular rollers 101 have several fan-shaped grooves 107 in their inner walls, several strip grooves 108 are formed on the inner walls of the fan-shaped grooves 107, and the fan-shaped grooves 107, the strip grooves 108, the annular grooves 105 and the circular holes 106 are all interconnected.
[0023] Correspondingly, when water condenses into droplets, it will pass through the strip groove 108 and enter the fan groove 107 due to gravity and the rotation of the annular roller 101, and be sucked out by the exhaust fan 104. While the strip groove 108 and several circular holes 106 are simultaneously exhausting air, the movement of the airflow around the annular roller 101 will be accelerated, further reducing the condensation of water droplets and the drying of water.
[0024] like Figure 6 As shown, a water tank 109 is fixedly installed inside the mounting frame 1. The water tank 109 is located directly below the annular roller 101. A composite die head ejector 110 is fixedly installed on the top inner wall of the mounting frame 1.
[0025] When the yarn falls onto the annular roller 101, water will condense on the surface of the annular roller 101 under the action of the cooling mechanism. The water will affect the quality of the yarn. During the rotation of the annular roller 101, the water will move and drip into the water tank 109 for collection under the action of gravity.
[0026] like Figure 5 , Figure 6 and Figure 7As shown, the cooling mechanism also includes a threaded cavity 2 opened in the annular drum 101. Annular boxes 201 are rotatably installed on the front and back of the annular drum 101, and both annular boxes 201 are connected to the threaded cavity 2. A water inlet pipe 202 is fixedly installed on the front of the corresponding annular box 201. A water pump 203 is fixedly installed on the front of the mounting bracket 1. The water pump 203 is connected to the water tank 109, and the end of the water inlet pipe 202 is connected to the water pump 203.
[0027] The water pump 203 draws the cooling water from the water tank 109 and injects it into the threaded cavity 2 through the water inlet pipe 202 and the annular box 201. When the cooling water passes through the threaded cavity 2, it will uniformly cool the outer wall of the annular roller 101.
[0028] like Figure 1 and Figure 6 As shown, a water outlet pipe 204 is fixedly installed on the back of the corresponding annular box 201, and a nozzle 205 is fixedly installed at the end of the water outlet pipe 204. An inclined filter plate 206 is fixedly installed inside the water tank 109. A winding roller 208 is fixedly sleeved on the rotating shaft 207. A drive motor 209 is fixedly installed on the front of the mounting frame 1, and the output end of the drive motor 209 is fixedly connected to the rotating shaft 207.
[0029] Correspondingly, the cooling water sprayed from the annular box 201 and the water outlet pipe 204 on the front of the annular roller 101 will re-enter the water tank 109 through the nozzle 205. Since the nozzle 205 has a narrow nozzle opening, the water flow will increase the contact area with the air when it is sprayed out, further cooling the cooled water and ensuring that the temperature of the cooling water is stable for continuous use.
[0030] like Figure 1 As shown, a guide roller 210 is rotatably installed inside the mounting frame 1. The fiber web 211 passes through the annular roller 101 and the guide roller 210 and is wound onto the take-up roller 208. Pulleys 212 are fixedly sleeved on the fixed support frame 103 and the rotating shaft 207, respectively. Synchronous belts 213 are sleeved on the two pulleys 212.
[0031] The drive motor 209 drives the rotating shaft 207 to rotate, the rotating shaft 207 drives the pulley 212 to rotate, the pulley 212 and the synchronous belt 213 drive the fixed support frame 103 to rotate, and the fixed support frame 103 rotates synchronously with the annular roller 101 to ensure stable cooling and collection of the fiber web 211 after it is ejected.
[0032] like Figure 6 and Figure 8As shown, the blower mechanism also includes an isosceles triangular block 3 fixedly sleeved on the rotating shaft 207. The isosceles triangular block 3 has two ends. An annular hollow block 301 is fixedly installed on the back of the mounting bracket 1. Several rectangular boxes 302 are fixedly installed on the annular hollow block 301. L-shaped grooves 303 are opened in the several rectangular boxes 302 respectively. The several L-shaped grooves 303 are all connected to the annular hollow block 301. Limiting springs 304 are fixedly installed on the inner walls of the several rectangular boxes 302 on the side away from each other. Rectangular plates 305 are fixedly installed on the ends of the several limiting springs 304 that are close to each other.
[0033] After the isosceles triangular block 3 leaves the corresponding two strip-shaped limiting plates 306, the strip-shaped limiting plates 306 and the rectangular plate 305 will reset under the elastic force of the limiting spring 304. Under the normal state of the limiting spring 304, the rectangular plate 305 will open the strip-shaped air intake groove to communicate with the outside. At this time, since the other two rectangular boxes 302 are connected to the outside, the reset of the rectangular plate 305 will replenish air through the strip-shaped air intake groove on the annular hollow block 301 and the other rectangular box 302.
[0034] like Figure 6 and Figure 8 As shown, strip-shaped limiting plates 306 are fixedly installed on the adjacent sides of several rectangular plates 305. The adjacent ends of several strip-shaped limiting plates 306 slide and extend to the outside of several rectangular boxes 302. Strip-shaped air inlet slots are opened on the left and right sides of several rectangular boxes 302. A rectangular jet box 307 is fixedly installed on the top of the mounting frame 1. An L-shaped air supply pipe 308 is fixedly installed on the left side of the rectangular jet box 307. The L-shaped air supply pipe 308 communicates with the annular hollow block 301.
[0035] The compressed air enters the annular hollow block 301 through the L-shaped groove 303, and is then injected into the L-shaped air supply pipe 308 from the annular hollow block 301. The air is then fed into the rectangular jet box 307 from the L-shaped air supply pipe 308. The gas ejected from the rectangular jet box 307 provides secondary cooling to the fiber web 211, which not only reduces the warping of the fiber web 211 caused by the difference in shrinkage rate and improves the uniformity of the fiber web 211, but also promotes the formation of a more uniform microporous structure in the fibers, thereby improving the fiber web 211's particulate matter interception rate.
[0036] This invention also discloses a processing technology for meltblown materials specifically for twin spinning, the steps of which are as follows: S1, Dehumidification: When water condenses into water droplets, it will pass through the strip groove 108 and enter the fan groove 107 due to gravity and the rotation of the annular roller 101. It will be sucked out by the exhaust fan 104. While the strip groove 108 and several circular holes 106 are simultaneously exhausting air, the movement of the airflow around the annular roller 101 will be accelerated, further reducing the condensation of water droplets and the drying of water. This will prevent condensate or cooling water from seeping into the fiber web 211 and leaving mineral residues after evaporation, which would affect the quality of the fiber web 211. S2, Water cooling: The water pump 203 will draw the cooling water in the water tank 109 and inject it into the threaded cavity 2 through the water inlet pipe 202 and the annular box 201. When the cooling water passes through the threaded cavity 2, it will uniformly cool the outer wall of the annular roller 101, thereby indirectly cooling the fiber web 211 and preventing the fiber web 211 from deforming due to uneven cooling. S3, Air cooling: The rectangular plate 305 will compress the air in the rectangular box 302. The compressed air will enter the annular hollow block 301 through the L-shaped groove 303. The air will be injected into the L-shaped air supply pipe 308 from the annular hollow block 301, and then input into the rectangular jet box 307 through the L-shaped air supply pipe 308. The gas ejected from the rectangular jet box 307 will perform secondary cooling on the fiber web 211, which will not only reduce the warping of the fiber web 211 caused by the difference in shrinkage rate, but also improve the uniformity of the fiber web 211. S4, Air replenishment: Under the normal state of the limiting spring 304, the rectangular plate 305 will open the strip air inlet slot to communicate with the outside. At this time, since the other two rectangular boxes 302 are connected to the outside, the rectangular plate 305 will replenish air through the annular hollow block 301 and the strip air inlet slot on the other rectangular box 302 when it is reset, thereby ensuring that the rectangular box 302 can quickly replenish air to prepare for the next blowing.
[0037] Working principle: During use, when the composite die head feeder 110 spins filament onto the annular roller 101, the exhaust fan 104 is activated. The exhaust fan 104 generates suction force through the hollow support frame 102, annular groove 105, fan-shaped groove 107, and several circular holes 106. As the filament is carried by the hot air, the suction force guides it onto the annular roller 101, providing a force that ensures the filament lands stably on the annular roller 101. Because the filament is at a high temperature, when it falls onto the annular roller 101... Under the action of the cooling mechanism, water will condense on the surface of the annular roller 101. The water will affect the quality of the yarn. During the rotation of the annular roller 101, the water will move and drip into the water tank 109 for collection under the action of gravity. Correspondingly, if the water condenses into water droplets, it will pass through the strip groove 108 and enter the fan groove 107 due to gravity and the rotation of the annular roller 101, and then be sucked out by the exhaust fan 104. While the strip groove 108 and several circular holes 106 are simultaneously exhausting air, the movement of the airflow around the annular roller 101 will be accelerated, which can effectively further reduce the condensation of water droplets. When the device is working, the drive motor 209 and water pump 203 are started. The drive motor 209 drives the rotating shaft 207 to rotate, which in turn drives the pulley 212 to rotate. The pulley 212 and the synchronous belt 213 drive the fixed support frame 103 to rotate. The fixed support frame 103 rotates synchronously with the annular roller 101 to ensure stable cooling and collection of the fiber web 211 after it is ejected. The water pump 203 draws cooling water from the water tank 109 and injects it into the threaded cavity 2 through the inlet pipe 202 and the annular box 201. When the cooling water passes through the threaded cavity 2, it will uniformly cool the outer wall of the annular roller 101, thereby indirectly cooling the fiber web. This can effectively prevent the fiber web from deforming due to uneven cooling. Correspondingly, the cooling water sprayed from the annular box 201 and the water outlet pipe 204 on the front of the annular roller 101 will re-enter the water tank 109 through the nozzle 205. Since the nozzle 205 has a narrow nozzle, the water flow will increase the contact area with the air when it is sprayed out, further cooling the cooled water again. When the rotating shaft 207 rotates, it will also drive the isosceles triangular block 3 to rotate. The two ends of the isosceles triangular block 3 will contact the two symmetrical strip limit plates 306. Under the action of the inclined surface of the isosceles triangular block 3, the two strip limit plates 306 will move away synchronously. The strip limit plates 306 will drive the rectangular plate 305 to move. The corresponding limit spring 304 will undergo compression deformation. The rectangular plate 305 will squeeze the air in the rectangular box 302. The squeezed air will enter the annular hollow block 301 from the L-shaped groove 303. The air will be injected from the annular hollow block 301 into the L-shaped air supply pipe 308, and then input into the rectangular jet box 307 from the L-shaped air supply pipe 308. The gas ejected from the rectangular jet box 307 will perform secondary cooling on the fiber web 211, which can reduce the warping of the fiber web 211 caused by the difference in shrinkage rate. After the isosceles triangular block 3 leaves the corresponding two strip-shaped limiting plates 306, the strip-shaped limiting plates 306 and the rectangular plate 305 will reset under the elastic force of the limiting spring 304. Under the normal state of the limiting spring 304, the rectangular plate 305 will open the strip-shaped air inlet slot to communicate with the outside. At this time, since the other two rectangular boxes 302 are connected to the outside, the reset of the rectangular plate 305 will replenish air through the annular hollow block 301 and the strip-shaped air inlet slots on the other rectangular boxes 302, thereby ensuring that the rectangular box 302 can quickly replenish air to prepare for the next blowing. The corresponding isosceles triangular block 3 will immediately connect to the next adjacent strip-shaped limiting plate 306 after leaving the corresponding strip-shaped limiting plate 306, thereby ensuring that the rectangular jet box 307 can continuously blow air.

10. A processing technology for meltblown material specifically for twin-spinning, employing the meltblown material processing equipment for twin-spinning as described in claims 1-9, characterized in that, The steps are as follows: S1, Dehumidification: When water condenses into water droplets, it will pass through the strip groove (108) and enter the fan groove (107) due to gravity and the rotation of the annular roller (101) and be sucked out by the exhaust fan (104). While the strip groove (108) and several circular holes (106) are simultaneously exhausting air, the movement of the airflow around the annular roller (101) will be accelerated, further reducing the condensation of water droplets and the drying of water, and preventing condensate or cooling water from seeping into the fiber web (211) and leaving mineral residues after evaporation, which would affect the quality of the fiber web (211). S2, Water cooling: The water pump (203) will draw the cooling water in the water tank (109) and inject it into the threaded cavity (2) through the water inlet pipe (202) and the annular box (201). When the cooling water passes through the threaded cavity (2), it will uniformly cool the outer wall of the annular roller (101), thereby indirectly cooling the fiber web (211) and preventing the fiber web (211) from deforming due to uneven cooling. S3, air cooling: The rectangular plate (305) will compress the air in the rectangular box (302). The compressed air will enter the annular hollow block (301) through the L-shaped groove (303). The air will be injected from the annular hollow block (301) into the L-shaped air supply pipe (308), and then input into the rectangular jet box (307) through the L-shaped air supply pipe (308). The gas ejected from the rectangular jet box (307) will perform secondary cooling on the fiber web (211) that has passed through, which will not only reduce the warping of the fiber web (211) caused by the difference in shrinkage rate, but also improve the uniformity of the fiber web (211). S4, Air replenishment: Under normal conditions of the limiting spring (304), the rectangular plate (305) will open the strip air inlet slot to communicate with the outside. At this time, since the other two rectangular boxes (302) are connected to the outside, the rectangular plate (305) will replenish air through the annular hollow block (301) and the strip air inlet slot on the other rectangular box (302) when it is reset, thereby ensuring that the rectangular box (302) can quickly replenish air to prepare for the next blowing.
