Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 An adjustable nonwoven meltblown mechanism in this embodiment includes a belt conveyor 1, a support frame 2 fixed on the upper surface of the belt conveyor 1, a spraying mechanism 3 for improving the uniformity of spraying on the left end of the upper surface of the support frame 2, and a cooling mechanism 4 for improving the cooling efficiency of the nonwoven fabric on the right end of the upper surface of the support frame 2.

[0023] In this embodiment, the cross-sectional shape of the support frame 2 is an inverted U-shape.

[0024] Please see Figure 2To ensure more uniform molten material during meltblowing, the spraying mechanism 3 in this embodiment includes a heating box 301 fixed to the left end of the upper surface of the support frame 2. An insulation layer 302 is fixed to the inner wall of the heating box 301. A storage box 303 is fixed inside the heating box 301. Multiple connecting seats 304 are fixed to the upper and lower ends of the left and right side walls of the inner cavity of the heating box 301. A heating pipe 305 is fixed between opposite sides of the upper and lower connecting seats 304. When the heating pipe 305 is connected to a power source, the surface temperature of the heating pipe 305 increases, thereby increasing the surface temperature of the storage box 303 located within the multiple heating pipes 305. A drive motor 306 is fixed at the center of the surface. The output shaft of the drive motor 306 passes through and extends into the inner cavity of the storage tank 303 and is fixed with a rotating rod 307. The rotating rod 307 is rotatably connected to the inner top wall of the storage tank 303 through a bearing. Multiple stirring rods 308 are fixed on the outer surface of the rotating rod 307. When the drive motor 306 is started, the output shaft of the drive motor 306 rotates, causing the rotating rod 307 to rotate. The rotation of the rotating rod 307 causes the multiple stirring rods 308 fixed on its surface to rotate. The rotation of the stirring rods 308 can stir the molten material in the inner cavity of the storage tank 303, so that the surface of the molten material is heated evenly.

[0025] In this embodiment, multiple heating tubes 305 are evenly distributed in the inner cavity of the storage tank 303. The upper surface of the storage tank 303 is connected to a feed pipe that extends through one end to the upper side of the heating tank 301. A sealing cap is threaded onto the upper surface of the feed pipe. Multiple stirring rods 308 are evenly distributed in the inner cavity of the storage tank 303. Several stirring supports are fixed on the outer surface of the stirring rods 308.

[0026] The storage tank 303 has a discharge pipe that extends from one end through the lower surface of the heating tank 301. A control valve is fixed on the outer surface of the discharge pipe, and a discharge nozzle is connected to the lower surface of the discharge pipe. The nonwoven fabric is placed on the belt surface of the belt conveyor 1, and then multiple control valves are opened, so that the molten material in the inner cavity of the storage tank 303 can be sprayed out to the surface of the nonwoven fabric through the discharge pipe and the discharge nozzle.

[0027] It should be noted that ensuring uniform heating of the molten material surface results in more uniform melting and spraying of the molten material, thus ensuring a good yield of nonwoven fabric and improving the production efficiency of nonwoven fabric.

[0028] Please see Figures 3-4To prevent adhesion of the nonwoven fabric surface, the cooling mechanism 4 in this embodiment includes a mounting box 401 fixed to the right end of the upper surface of the support frame 2. A fan 402 is fixed in the middle of the upper surface of the mounting box 401. The air inlet of the fan 402 is connected to a filter screen 403. When the fan 402 is started, air is drawn in through the filter screen 403 and filtered. The drawn-in air can then enter the inner cavity of the mounting box 401 through the air outlet of the fan 402. Cooling plates 404 are fixed at both ends of the main wall. A hollow tube 405 is fixed at the right end of the lower surface of the support frame 2. Multiple air jets 406 are connected to the lower surface of the hollow tube 405. After being cooled by the cooling plates 404, the air temperature drops and then enters the inner cavity of the hollow tube 405. Finally, it is sprayed out through the air jets 406. As the belt is conveyed, the molten material adheres to the surface of the nonwoven fabric. By blowing air onto the surface of the nonwoven fabric through the multiple air jets 406, the meltblown material on the surface of the nonwoven fabric can be cooled quickly.

[0029] In this embodiment, the air outlet of the fan 402 is connected to the inner cavity of the mounting box 401, the filter screen cover 403 includes a fixing ring and a filter plate, and the hollow tube 405 is connected to the inner cavity of the mounting box 401.

[0030] It should be noted that the cooling chip 404 includes a heat-absorbing end and a heat-releasing end. The heat-absorbing end is located in the inner cavity of the mounting box 401, and the heat-releasing end is located on the back of the mounting box 401. The heat-absorbing end absorbs heat from the air and then dissipates it through the heat-releasing end.

[0031] Understandably, blowing air onto the surface of the nonwoven fabric through multiple jet nozzles 406 can rapidly cool the meltblown material on the surface of the nonwoven fabric, thus preventing adhesion from occurring on the surface of the nonwoven fabric.

[0032] The working principle of the above embodiments is as follows:

[0033] (1) When melting and blowing nonwoven fabric, first connect the heating tube 305 to the power supply. The temperature of the surface of the heating tube 305 rises, thereby raising the temperature of the surface of the storage box 303 located in the multiple heating tubes 305. Then start the drive motor 306. The output shaft of the drive motor 306 rotates, driving the rotating rod 307 to rotate. The rotation of the rotating rod 307 causes the multiple stirring rods 308 fixed on its surface to rotate. The rotation of the stirring rods 308 can stir the molten material in the inner cavity of the storage box 303, so that the surface of the molten material is heated evenly. Then place the nonwoven fabric on the belt surface of the belt conveyor 1. Then open multiple control valves, so that the molten material in the inner cavity of the storage box 303 can be sprayed out to the surface of the nonwoven fabric through the feeding pipe and the discharge nozzle.

[0034] (2) Start the fan 402. The air inlet of the fan 402 draws in air through the filter screen 403 and filters the air. The air drawn in can enter the inner cavity of the mounting box 401 through the outlet of the fan 402. After being cooled by the cooling plate 404, the air temperature drops. Then it enters the inner cavity of the hollow tube 405 and is finally sprayed out through the jet nozzle 406. As the belt is conveyed, the molten material adheres to the surface of the nonwoven fabric. By blowing air onto the surface of the nonwoven fabric through multiple jet nozzles 406, the meltblown material on the surface of the nonwoven fabric can be cooled quickly.
