Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a meltblown nonwoven fabric device. Background Technology

[0002] Nonwoven fabrics are characterized by moisture resistance, breathability, flexibility, and recyclability. They can be used in various industries, such as masks, clothing, medical applications, and filling materials. Nonwoven fabrics are mostly made from polypropylene granules as raw materials, produced in a continuous one-step process involving high-temperature melting, spinning, laying, and hot-pressing. Meltblowing equipment is required in the production process of nonwoven fabrics.

[0003] The meltblown nonwoven fabric production process uses high-speed hot air to stretch molten polymers into ultrafine fibers, which are then condensed into nonwoven fabric on a receiving device. This technology can produce nonwoven fabrics with fiber diameters of less than a few micrometers, which have high filtration efficiency and air permeability. However, in the current meltblown production process, a large amount of high-temperature hot air is required to form ultrafine fibers from the polymer melt. If this hot air cannot be recycled, energy needs to be continuously consumed to generate new hot air, which will lead to a significant increase in energy consumption during the production process and increase production costs.

[0004] Therefore, it is necessary to provide a meltblown nonwoven fabric device to solve the above-mentioned technical problems. Utility Model Content

The nonwoven fabric meltblown device includes: a workbench 1, a square cover 2 fixedly connected to the top of the workbench 1, a meltblown mechanism 3 fixedly connected inside the square cover 2, an air suction pump 4 fixedly connected to the top of the square cover 2, an inlet pipe 5 fixedly connected to the bottom of the air suction pump 4, the inlet pipe 5 penetrating through the square cover 2 and extending into the interior of the square cover 2, a return pipe 6 fixedly connected to the top of the air suction pump 4, an arch frame 7 fixedly connected to the outside of the workbench 1, a heating cylinder 8 fixedly connected to the top of the arch frame 7, a purification cylinder 9 fixedly connected to the top of the heating cylinder 8, an air supply pipe 10 fixedly connected to the bottom of the purification cylinder 9, the bottom of the air supply pipe 10 fixedly connected to the top of the heating cylinder 8, and a screw block 11 threadedly connected to the other end of the purification cylinder 9.

The other end of the purification pipe 13 is inserted into the other end of the return suction pipe 6. A support plate 14 is fixedly connected to the outside of the arch frame 7. An exhaust pump 15 is fixedly connected to the top of the support plate 14. An exhaust pipe 16 is fixedly connected to the outside of the exhaust pump 15. The other end of the exhaust pipe 16 is fixedly connected to the outside of the heating cylinder 8. An exhaust pipe 17 is fixedly connected to the outside of the exhaust pump 15. A gas collection box 18 is fixedly connected to the top of the square cover 2. The other end of the exhaust pipe 17 is fixedly connected to the top of the gas collection box 18. A side air pipe 19 is fixedly connected to one side of the gas collection box 18. A side box 20 is fixedly connected to one side of the square cover 2. The other end of the side box 20 is fixedly connected to the outside of the side air pipe 19.

[0030] The hot air used by the meltblown mechanism 3 inside the square cover 2 during operation is absorbed by the suction pump 4 and then filtered through the purification cylinder 9 to remove impurities before being transported to the heating cylinder 8 for reheating. Although the heat of the hot air is reduced, it is not completely cooled and can be quickly heated in the heating cylinder 8. The hot air drawn from the heating cylinder 8 by the exhaust pump 15 is collected by the air collection box 18. The reheated hot air is transported to the inside of the square cover 2 through the side air pipes 19 that are equidistantly arranged on both sides of the air collection box 18, which helps to reduce the energy consumption of the nonwoven meltblown device during operation.

[0031] A vertical limiting tube 21 is fixedly connected inside the side box 20. A vertical rod 22 is movably connected inside the vertical limiting tube 21. A guide plate 23 is fixedly connected to the outside of the vertical rod 22. A semi-groove block 24 is fixedly connected inside the side box 20. A displacement rod 25 is fixedly connected to the bottom of the guide plate 23. The displacement rod 25 passes through the guide plate 23 and extends to the outside of the guide plate 23. The displacement rod 25 is slidably connected to the semi-groove block 24. A semi-circular groove 26 is opened at the top of the side box 20. The displacement rod 25 is slidably connected to the semi-circular groove 26. A horizontal limiting tube 27 is fixedly connected to the inner wall of the side box 20. A horizontal bar 28 is movably connected inside the horizontal limiting tube 27. A horizontal plate 29 is fixedly connected to the outside of the horizontal bar 28. A fixing block 30 is fixedly connected to the top of the horizontal plate 29. A short column 31 is fixedly connected to one side of the fixing block 30.

[0032] Currently, the guide vanes 23 are all integral pieces, and when adjusting the airflow direction, the direction of hot air can only be changed as a whole. The angle of the guide vanes 23 can be changed by moving the vertical rods 22 on the side box 20. Furthermore, by setting two equally spaced guide vanes 23, each individual guide vane 23 can guide hot air at different angles. The angle of the horizontal plate 29 can be changed by adjusting the height of the threaded rod 35. The different heights of the threaded rod 35 can be limited by turning the threaded block 36. When the meltblown mechanism 3 is operating, changing the angles of the horizontal plate 29 and the guide vanes 23 allows the hot air to play a better role.

[0033] A support block 37 is fixedly connected to the inner wall of the heating cylinder 8, and a ceramic heater 38 is fixedly connected to the top of the support block 37.

[0034] The support block 37 can support the ceramic heater 38, and the ceramic heater 38 can quickly convert electrical energy into heat energy to increase the temperature of the hot air.

[0035] The purification cylinder 9 is equipped with a velvet plate 39 inside, and the screw block 11 is equipped with a fine filter plate 40 inside.

[0036] Fine filter plate 40 collects and blocks fine impurities in the recovered hot air, while cloth plate 39 can better filter impurities in the hot air.

[0037] A conveyor belt 41 is fixedly connected to the top of the workbench 1.

[0038] The nonwoven fabric is evenly sprayed onto the conveyor belt 41 by the meltblown mechanism 3, which facilitates its rapid transfer to the next process.

[0039] The bottom of the workbench 1 is fixedly connected with casters 42.

[0040] The casters 42 increase the overall flexibility of the device's movement.

[0041] The working principle of the nonwoven meltblown device provided by this utility model is as follows: When the device is in operation, the operator starts the suction pump 4 on the square cover 2. When the suction pump 4 is in operation, the suction pipe 5 absorbs the hot air generated by the meltblown operation inside the square cover 2. The hot air is then transported to the purification cylinder 9 through the return suction pipe 6 to filter the meltblown impurities in the hot air. After filtration, the hot air is transported to the heating cylinder 8 through the air supply pipe 10. Then, the hot air inside the heating cylinder 8 is discharged to the air collection box 18 through the exhaust pump 15 for collection. Finally, the heated hot air is returned to the square cover 2 through the side air pipe 19. The hot air return system can make the meltblown process more stable and efficient, reduce the production interruption and adjustment time caused by temperature fluctuations or unstable airflow, improve the actual operating time and production efficiency of the equipment, and reduce energy consumption.

[0042] Compared with related technologies, the nonwoven fabric meltblown device provided by this utility model has the following beneficial effects:

The device uses an inlet pipe 5, an air pump 4, a return pipe 6, a purification cylinder 9, a heating cylinder 8, an exhaust pump 15, and a side air pipe 19 in cooperation to allow the air pump 4 to recover the hot air from the meltblown process into the purification cylinder 9 for impurity removal. Then, the air is transported to the heating cylinder 8 for further heating and then transported back into the device through the side air pipe 19. By recovering the hot air, the energy efficiency of the entire meltblown process is improved. This not only meets the requirements of sustainable development but also helps enterprises maintain competitiveness in a market environment with fluctuating energy prices.
