[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1-3 As shown, a spunbond nonwoven web-forming machine proposed by the utility model comprises an equipment frame 1, an extruder 2 is fixed on the upper end of the equipment frame 1, an extrusion box 4 is fixed at the discharge port of the extruder 2, a pressure sensor 42 is fixed in the extrusion box 4, an air pump 43 is fixed on the upper end of the extrusion box 4, high-pressure gas is injected by the air pump 43, and the solution is quickly extruded without destroying the surface tension of the solution, a group of fiber nozzles 6 are fixed at the bottom of the extrusion box 4, a telescopic groove 7 is opened in the extrusion box 4 and at a position corresponding to the fiber nozzle 6, a baffle 71 is slidably connected in the telescopic groove 7, a telescopic cylinder 72 for driving the baffle 71 to telescope is fixed to the outer wall of the telescopic groove 7, an exhaust pipe 54 is fixed at the bottom of the extrusion box 4 and at a position corresponding to the fiber nozzle 6, a liquid level sensor 41 is fixed on the top of the extrusion box 4, a control panel 44 is fixed on the outer wall of the extrusion box 4, a conveyor belt 3 is installed on the equipment frame 1, the height of the conveyor belt 3 is lower than the height of the extruder 2, and the extrusion box 4 is located above the conveyor belt 3.

[0019] An installation cavity 5 is provided in the side wall of the extrusion box 4 and at a position corresponding to the exhaust pipe 54. A high-pressure fan 53 is fixed in the installation cavity 5. An air inlet 51 is provided in the side wall of the installation cavity 5. A dustproof net 52 is fixed in the air inlet 51. The high-pressure fan 53 drives the gas in the installation cavity 5 to be blown out from the exhaust pipe 54, and the external air enters from the air inlet 51. At this time, the dustproof net 52 can be used to block the dust in the air to prevent the dust from adhering to the non-woven cloth.

[0020] In this embodiment, the entire device is first connected to an external power supply, and the raw materials are melted by the extruder 2 and enter the extrusion box 4, and then the air pump 43 is used to inject high-pressure gas to quickly extrude the solution without destroying the surface tension of the solution. At this time, the high-pressure fan 53 is used to drive the high-pressure air to blow out from the exhaust pipe 54 to realize the web processing of the non-woven fabric. In this process, the higher the air pressure in the extrusion box 4, the faster the fiber nozzle 6 will extrude, and the extrusion speed can be easily controlled. The liquid level height in the extrusion box 4 can be monitored by the liquid level sensor 41, and the feeding speed of the extruder 2 can be controlled to avoid the problem of lack of material or too high liquid level. At the same time, when processing non-woven fabrics of different widths, the telescopic cylinders 72 on both sides can be used to drive the baffle 71 to extend and retract, thereby blocking the upper end of the fiber nozzle 6, so that the fiber nozzle 6 of the specified width can be extruded. The operation is relatively convenient and no subsequent cutting work is required, which improves the practicality of the web forming machine.

[0021] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
