[0043] The heating device is an electric heating wire, which heats the upper welding cylinder 207 and the lower welding cylinder 204. In some other embodiments of the present invention, the heating device is an electromagnetic heater, which heats the upper welding cylinder 207 and the lower welding cylinder 204, has a good heating effect, and can achieve contactless heating.

[0044] The upper welding tube 207 and the lower welding tube 204 are provided with temperature sensors, which can monitor the temperature of the upper welding tube 207 and the lower welding tube 204, so as to confirm whether the temperature of the upper welding tube 207 and the lower welding tube 204 is within a suitable range.

[0045] A pressure sensor is provided below the upper welding cylinder 207, and the pressure sensor is used to monitor the pressure on the upper welding cylinder 207. In this embodiment, the compression amount of the upper welding cylinder 207 when melting the wire mesh belt 202 is 0.1 mm, that is, when the upper welding cylinder 207 is pressed down, the compression amount of the wire mesh belt 202 is 0.1 mm. At this time, the pressure detected by the pressure sensor is set as P1, P1 is the initial pressure, and the pressure detected by the pressure sensor when the wire mesh belt 202 is heated and melted to reach the melting welding standard is P2. When the wire mesh belt 202 is heated and melted, the pressure on the upper pressure cylinder is reduced. The pressure detected by the pressure sensor at this time is set as Px. When Px is reduced to P2, the melting degree of the wire mesh belt 202 reaches the melting welding standard. At this time, the melting welding cylinder moves to raise the upper welding cylinder 207, and the wire mesh belt 202 is cooled to complete the melting welding. The specific value of P2 may vary due to the installation error of the pressure sensor and the different melting welding standards of the wire mesh belt 202. Therefore, in the specific implementation, the P2 value can be obtained by experiment or experience. In summary, the pressure can be detected by the pressure sensor to control the action time of the upper welding cylinder 207, ensuring that the wire mesh belt 202 has a better melting standard.

The air nozzle 209 receives a high-pressure airflow. After the mesh bag 210 is cut, the air nozzle 209 blows out an airflow to blow the mesh bag 210 into the barrel 211 for collection.

[0047] The reel 1 is connected to a feeding motor for driving the reel 1 to rotate. When the third clamp 212 and the fourth clamp 213 pull the wire mesh belt 202 to move, the feeding motor drives the reel 1 to rotate, and the rolled wire mesh material 201 rotates, thereby preventing the wire mesh belt 202 from being tensilely deformed.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
