[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The following embodiments are implemented based on the technical solution of the present invention, providing detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0026] Example 1

[0027] A meltblown pressure-stabilized gas supply device, such as Figure 1As shown, the system includes an air compressor 2, an air tank 3, an air heater 4, and a spinning box 5, all connected in sequence via an air duct 1. A pressure regulator 6, a pressure gauge 7, and a flow controller 8 are installed between the air tank 3 and the air heater 4. Through multiple pressure stabilization processes, including air storage and stabilization, the air pressure and flow rate are more stable, reducing the impact on meltblown fiber stretching caused by unstable hot air pressure and flow.

[0028] Example 2

[0029] A meltblown pressure-stabilized gas supply device, comprising:

[0030] Air compressor 2;

[0031] Air storage tank 3 is connected to air compressor 2, and compressed air generated by air compressor 2 enters the air storage tank.

[0032] Air duct 1, which connects the air storage tank 3 to the meltblown air supply pipe of the spinning box 5;

[0033] Voltage regulator 6, which is installed in the middle of air duct 1;

[0034] Flow controller 8 is installed on air duct 1, located after voltage regulator 6;

[0035] Air heater 4 is connected to air duct 1 and is located after flow controller 8.

[0036] Air compressor 2 produces compressed air at a pressure of 0.6–1.0 MPa. Air tank 3 has a storage capacity of 2–10 m³. 3 The gas storage tank 3 can withstand a pressure >1.0MPa. The pressure regulator 6 consists of two units, front and rear, with pressure settings from high to low. The first regulator (front regulator 61) is set within the range of 0.5-0.6MPa, and the second regulator (rear regulator 62) is set within the range of 0.4-0.5MPa. Pressure gauges 7 are installed at both ends of both regulators.

[0037] In this invention, compressed air is generated by an air compressor. The compressed air enters an air storage tank for storage and pressure stabilization. The high-pressure air in the air storage tank enters an air pipeline and is reduced and stabilized by a pressure regulator. After pressure stabilization, the compressed air enters a flow controller to control the flow rate, and then enters an air heater. After being heated by the air heater, the air enters the spinning box, and the hot air stretches the fibers ejected from the spinneret.
