[0020] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 to 3 , the present invention provides a technical solution: a non-woven fabric guiding device for mask production, including a third U-shaped frame 25 connected to the top of the operating table 3 and opening downward. Through grooves 15 are provided on the side walls of the third U-shaped frame 25. A third guiding roller 20 and a second guiding roller 7 are connected to be lifted up and down in the through groove 15 from top to bottom. A slide block 12 is slidably connected in the through groove 15. The end of the second guiding roller 7 is rotatably connected between the two slide blocks 12. A second guiding rod 14 passing through the through groove 15 is vertically connected to the bottom of the slide block 12. A return spring 13 is coaxially provided on the second guiding rod 14. The return spring 13 is located between the slide block 12 and the inner bottom surface of the through groove 15. As Figure 1 , 2 shown, after the non-woven fabric passes between the second guiding roller 7 and the third guiding roller 20, a force is generated on the second guiding roller 7 at the bottom. Under the action of the pressure, the slide block 12 is driven to slide up and down in the through groove 15. At this time, the return spring 13 at the bottom of the slide block 12 generates an upward elastic force under the pressing action, which can not only avoid damage to the non-woven fabric caused by excessive tension, but also ensure the transportation of the non-woven fabric.

[0022] As Figure 1 , 2As shown in the figure, a second U-shaped frame 18 with a downward opening is arranged above the third U-shaped frame 25. The end of the second U-shaped frame 18 is bent and extended into the through groove 15. The third guide roller 20 is rotatably connected between the two bent parts. One end of the third guide roller 20 is connected to the motor 16 fastened to the outer wall of the second U-shaped frame 18. A second electric telescopic rod 17 is connected between the top of the second U-shaped frame 18 and the top of the third U-shaped frame 25. The top of the third U-shaped frame 25 is symmetrically connected with third guide rods 19. The tops of the third guide rods 19 penetrate through the second U-shaped frame 18. The second electric telescopic rod 17 pushes the second U-shaped frame 18 to slide up and down above the third U-shaped frame 25. Since the third guide roller 20 is rotatably connected to the end of the second U-shaped frame 18, the up and down sliding adjustment of the third guide roller 20 can be realized, which is beneficial for the user to adjust the distance between the third guide roller 20 and the second guide roller 7, improving the practicability of the device.

[0023] As Figure 2 , 3 As shown in the figure, an installation frame 24 is connected between the side walls of the second U-shaped frame 18. A threaded rod 23 is rotatably connected to the installation frame 24. The threads on the threaded rod 23 are symmetrically arranged along its center. Connecting blocks 22 are symmetrically connected to the threaded rod 23. A first guide rod 1 parallel to the threaded rod 23 is arranged in the installation frame 24. The first guide rod 1 penetrates through the connecting block 22. A vertical rod 8 is vertically connected to the bottom of the connecting block 22. U-shaped limit plates 9 are rotatably connected to the sides of the lower ends of the two vertical rods 8 close to each other. One side of the U-shaped limit plate 9 is fastened with a screw rod 10 penetrating through the vertical rod 8. An adjusting nut 11 is connected to the end of the screw rod 10. The side of the non-woven fabric passing through the second guide roller 7 and the third guide roller 20 is located inside the U-shaped limit plate 9. Since the two U-shaped limit plates 9 can be slidably adjusted by rotating the threaded rod 23, the distance between the two U-shaped limit plates 9 can be quickly adjusted, thus meeting the guiding and transporting of non-woven fabrics of different widths. And the U-shaped limit plate 9 is connected to the lower end of the vertical rod 8 through the screw rod 10 and the adjusting nut 11, so that the tightness of the connection between the U-shaped limit plate 9 and the vertical rod 8 can be adjusted, and fine adjustment can be made according to the movement of the non-woven fabric, avoiding damage to the side of the non-woven fabric caused by excessive pressure.

[0024] In summary, for the non-woven fabric guiding device for mask production, when in use, a first guide roller 2 and a cloth roller 21 are respectively connected to both ends of the operation table 3. The third U-shaped frame 25 is located between the first guide roller 2 and the cloth roller 21. A first U-shaped frame 5 with a downward opening is vertically connected to the top of the operation table 3. The first guide roller 2 is connected to the inside of the first U-shaped frame 5 through a first electric telescopic rod 4. A chute 6 is opened on the side wall of the first U-shaped frame 5. The end of the first guide roller 2 is slidably connected to the chute 6;

[0025] The non-woven fabric moves from the fabric roll 21 to between the second guide roller 7 and the third guide roller 20, and extends to the bottom of the first guide roller 2. The side of the non-woven fabric passing between the second guide roller 7 and the third guide roller 20 is limited by the U-shaped limit plate 9, which can ensure the stable sliding of the non-woven fabric, avoid deviation, and thus improve the quality of mask production. At the same time, the U-shaped limit plate 9 can be slidably adjusted by rotating the threaded rod 23, so as to meet the use of non-woven fabrics of different widths, and further improve the practicability of the device.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
