[0060] Embodiment three:

[0061] A nonwoven fabric production process of a medical nonwoven fabric meltblown machine comprises the following steps:

[0062] S1, putting the raw material into the melting tank 10 for melting, conveying the molten raw material through the conveying pump 708, and spraying it through the nozzle on one side of the spinneret 701 to form molten fibers and attach them to the receiving conveyor belt 101 to form a non-woven fabric;

[0063] S2, at the same time, the pressing and cutting assembly 2 is lowered by the hydraulic rod 3, and the pressing roller 202 is driven by the second motor 2011 to rotate and press the non-woven fabric, so that the thickness difference of each part of the non-woven fabric is reduced, and at the same time, the ultrasonic cutting knife 209 is started to cut the redundant parts on both sides of the non-woven fabric, so as to obtain the required specifications of the non-woven fabric;

[0064] S3, wherein the rotation of the pressure roller 202 can drive the driving plate 505 in the driving structure 5 to move, and as the smooth portion and the protruding portion on one side of the driving plate 505 contact the fixed block 703, the spinneret plate 701 will be driven to move laterally and can return to its original position through the return assembly 8, and this process is repeated, so that the molten fibers can be evenly distributed, the defects of the non-woven fabric are reduced, and the quality and performance of the product are improved;

[0065] S4. When the driving plate 505 moves, the cleaning roller brush 604 in the cleaning assembly 6 will also rotate accordingly, thereby cleaning the residual fibers on the outside of the receiving conveyor belt 101 and collecting them in the receiving tray 9, thereby achieving the effect of recycling and preventing the residual fibers from affecting the production and transportation of non-woven fabrics, thereby improving the production quality of non-woven fabrics.

[0066] Working principle: First, the raw materials for making non-woven fabrics are placed in the melting tank 10 for melting, and then the spinneret 701 in the spinneret mechanism 7 is started, so that the melted raw materials can be transported through the second conveying pipe 711, the telescopic pipe 710 and the first conveying pipe 709, so that molten fibers are ejected through the spinneret 701 and received by the receiving conveyor belt 101 in the receiving component 1. With the transmission of the receiving conveyor belt 101, the molten fibers are slowly cooled into non-woven fabrics;

[0067] Before the production of non-woven fabrics, the height of the pressing and cutting assembly 2 is adjusted by the hydraulic rod 3 according to the required specifications of the non-woven fabrics, and the pressing roller 202 is driven to rotate by the second motor 2011, so that the non-woven fabrics can be more stable during transportation, and the non-woven fabrics are rolled into the required thickness, so that the thickness difference of the non-woven fabrics at various places is reduced, and the production quality of the non-woven fabrics is improved. The rolling process helps to closely combine the fiber layers, so that the structure of the non-woven fabrics is more stable and not easy to be delaminated or deformed;

[0068] At the same time, the inclined electric telescopic rod 207 in the pressing and cutting component 2 is started, so that the ultrasonic cutting knife 209 can contact the non-woven fabric, and the air pump 203 can also be used to evacuate and inhale air, so that the pneumatic rods 205 can move away from or close to each other, thereby adjusting the distance between the ultrasonic cutting knives 209, wherein the working range of the ultrasonic cutting knife 209 does not exceed the metal pad cutting belt 102, and the uneven parts on both sides of the non-woven fabric can be cut off by starting the side support plate 208, and with the conveyance of the receiving conveyor belt 101 and its own gravity, it falls into the receiving tray 9 for collection, which is convenient for recycling and reuse, thereby saving resource consumption;

[0069] When the pressing roller 202 rotates, it can drive the rotating disk 501 in the driving structure 5 to move, thereby driving the eccentric connecting plate 502, the adaptive electric telescopic rod 503 and the extension plate 504 to swing. The swing of the extension plate 504 can drive the driving plate 505 to move. Due to the arrangement of the guide rail 506 and the connecting frame 507, the driving plate 505 can move back and forth along a fixed track. When the driving plate 505 moves, the smooth part and the protruding part on one side thereof will contact the fixed block 703, so that the fixed block 703 can drive the carrier frame 702 and the spinneret plate 701 to move horizontally, so that the molten fibers ejected from the spinneret plate 701 can be evenly distributed, thereby reducing the defects of the non-woven fabric and improving the quality and performance of the product.

[0070] When the spinneret 701 moves, the return spring 805 in the return assembly 8 is compressed, and the angle between the first connecting rod 802 and the second connecting rod 803 becomes smaller, and the stabilizing slide bar 804 also slides on the inner side of the fixed plate 806, thereby stabilizing the movement of the spinneret 701, and the elastic force of the return spring 805 makes the spinneret 701 return to its original position, so that the spinneret 701 can move back and forth laterally, wherein the telescopic tube 710 can bend back and forth, thereby adapting to the movement of the spinneret 701, and will not affect the transportation of the molten raw materials;

[0071] Among them, the driving plate 505 will drive the continuous drive gear 601 in the cleaning component 6 to rotate while moving, and the rotation of the continuous drive gear 601 will drive the first pulley 602 to rotate. The rotation of the first pulley 602 drives the second pulley 603 to rotate through the belt, and the second pulley 603 will drive the cleaning roller brush 604 to rotate. The rotation of the cleaning roller brush 604 can brush off the residual fibers on the outside of the receiving conveyor belt 101, thereby preventing the residual fibers from affecting the production quality of the non-woven fabric.

[0072] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
