[0002] Non-woven fabric is a fiber material made without going through the textile process. It is composed of short fibers or long fibers combined together by physical mechanics, chemistry or thermodynamics. It does not require weaving or weaving. It has a fiber structure and is soft, breathable, water-resistant and wear-resistant. It is widely used in medical, health, environmental protection, agriculture, construction, home textiles and other fields. It is a functional and new material.

The number of the sealing disks 13 is the same as the number of the upper nozzles of the coating nozzle 3. The top of the sealing disk 13 contacts the bottom of the nozzle of the coating nozzle 3, so that the sealing disk 13 provides sealing protection for the bottom of the nozzle.

The sealing disk 13 on the hanging cross plate 12 corresponds to the nozzle on the coating nozzle 3 one by one, so as to provide sealing protection for the bottom of the nozzle, and when the rotating rod 9 rotates, the external thread 2 on the rotating rod 9 can drive the movable plate 15 to move downward along the outer side of the slide plate 14, and the movable plate 15 drives the hanging cross plate 12 to move downward through the slider 16, so that the nozzle of the coating nozzle 3 is opened, and the hanging cross plate 12 can drive the slide bar 19 to move downward along the V-shaped groove on the device housing 1 through the positioning plate 18. When the slide bar 19 moves to the inclined end of the V-shaped groove, the slide bar 19 drives the hanging cross plate 12 to move obliquely downward through the positioning plate 18, and the hanging cross plate 12 drives the slider 16 to move along the inner side of the movable plate 15, and stretches the tension spring 17, so that the hanging cross plate 12 can be moved away from the coating nozzle 3, thereby achieving the effect of sealing protection and automatic opening.

[0024] The clearing mechanism includes three pins 20 which are symmetrically distributed and fixedly installed on the top of the sealing disk 13. The outer side of the pin 20 contacts the inner side of the nozzle of the coating nozzle 3. A synchronous belt 21 is rotatably installed between the multiple sealing disks 13. The synchronous belt 21 is located on the inner side of the suspension horizontal plate 12, so that the multiple sealing disks 13 can rotate synchronously. A conical wheel 22 is fixedly installed at the bottom of the sealing disk 13 located on the far right side of the suspension horizontal plate 12. The end of the slide rod 19 close to the positioning plate 18 is fixedly installed with a conical wheel 22 which cooperates with the conical wheel 22. The conical wheel 23 can drive the corresponding sealing disk 13 to rotate through the conical wheel 1 22. A rack plate 24 is fixedly installed in the V-shaped groove of the device housing 1. The rack plate 24 is located at the vertical end of the V-shaped groove on the device housing 1. A gear 25 that cooperates with the rack plate 24 is fixedly installed at one end of the slide bar 19 away from the conical wheel 23, so that when the slide bar 19 moves downward, the slide bar 19 can rotate by the cooperation of the rack plate 24 and the gear 25. The outer diameter of the gear 25 is smaller than the outer diameter of the slide bar 19. When the slide bar 19 moves downward along the V-shaped groove on the device housing 1, the gear 25 on the slide bar 19 can move along the outer side of the rack plate 24, so that the gear 25 drives the slide bar 19 to rotate, and the slide bar 19 drives the conical wheel 1 22 to rotate through the conical wheel 2 23, so that the conical wheel 1 22 drives the corresponding sealing disk 13 to rotate, and the sealing disk 13 drives the remaining sealing disks 13 to rotate synchronously through the synchronous belt 2 21, so that the three pins 20 on the sealing disk 13 scrape out the residue on the inner side of the nozzle on the coating nozzle 3, ensuring the normal coating of the coating nozzle 3, thereby achieving the anti-blocking effect and improving the convenience of cleaning the coating nozzle 3.

[0025] Working principle: First, the staff loads the non-woven fabric under the two feed rollers 4 and starts the drive motor 33. The drive motor 33 drives the corresponding rotating rod 9 to rotate. The rotating rod 9 drives another rotating rod 9 to rotate synchronously through the synchronous belt 10. The two rotating rods 9 drive the fixed plate 7 to move upward through the external thread 1 on the outer side and the moving cylinder 11. The fixed plate 7 drives the two mounting plates 6 to move along the inner side of the device shell 1, so that the mounting plate 6 steadily drives the two pressing rollers 5 to contact the bottom of the non-woven fabric, so that the non-woven fabric bulges upward and leans against the bottom of the coating nozzle 3, and the top of the non-woven fabric is against the outer side of the two feed rollers 4, so as to stretch the non-woven fabric and solve the problem of wrinkles of the non-woven fabric. At the same time, the rotating rod 9 drives the moving plate 15 to move downward along the outer side of the slide plate 14 through the external thread 2, so that the moving plate 15 drives the hanging cross plate 12 to move downward through the slider 16, and the nozzle of the coating nozzle 3 is opened, and the hanging cross plate 12 drives the slide bar 19 on the positioning plate 18 to move downward along the V-shaped groove on the device shell 1 The sliding rod 19 drives the gear 25 to move along the outer side of the rack plate 24. The gear 25 cooperates with the rack plate 24 to drive the sliding rod 19 to rotate. The sliding rod 19 drives the conical wheel 1 22 to rotate through the conical wheel 2 23. The conical wheel 1 22 drives the corresponding sealing disk 13 to rotate. The sealing disk 13 drives the other sealing disks 13 to rotate synchronously through the synchronous belt 2 21, so that the three pins 20 on the sealing disk 13 rotate along the inner side of the nozzle of the laminating nozzle 3 to scrape out the residue inside the nozzle. Subsequently, the slide bar 19 moves to the inclined end of the V-shaped groove, and the slide bar 19 moves along the inclined end of the V-shaped groove, and drives the hanging cross plate 12 to move downward at the same inclination through the positioning plate 18, so that the hanging cross plate 12 drives the slider 16 to move along the inner side of the moving plate 15, and the hanging cross plate 12 can be away from the coating nozzle 3. Finally, the feeding roller 4 and the pressing roller 5 convey the non-woven fabric, and the extruder 2 coats the non-woven fabric in a moving state through the coating nozzle 3, thereby achieving the effect of rapid installation and uniform coating.

[0026] Example 2: Please refer to Figure 1-Figure 5 The present embodiment further explains the first embodiment. A baffle 26 is rotatably installed on the inner side of the feed port of the device housing 1 in the figure. The height of the baffle 26 is less than the height of the feed port on the device housing 1. A pull strip 27 is fixedly installed on the outer side of the baffle 26 to facilitate the loading of the non-woven fabric into the device housing 1. Two symmetrically distributed baffles 28 are fixedly installed on the bottom of the mounting plate 6. The outer side of the baffle 28 is in contact with the inner side of the device housing 1. The four baffles 28 are respectively located directly below the four slide grooves on the device housing 1. The length and width of the baffle 28 are greater than the length and width of the slide groove on the device housing 1, providing a seal for the slide groove on the device housing 1.

[0027] In this embodiment: the staff can rotate the baffle 26 on the feed port of the device housing 1 upward to open the feed port, so as to facilitate the loading of the non-woven fabric into the interior of the device housing 1, thereby improving the convenience of installing the non-woven fabric and the two pressing rollers 5. When the mounting plate 6 moves, it can drive the baffle 28 to move along the outer side of the slide groove on the device housing 1, thereby providing a seal for the slide groove and preventing overflow of the coating film from flowing out of the slide groove.

[0028] Example 3: Please refer to Figure 6-Figure 8 , this embodiment further explains other embodiments. A guide rod 29 that slides through the slider 16 is fixedly installed on the inner side of the movable plate 15 in the figure to improve the stability of the movement of the slider 16. A material receiving frame 30 is fixedly installed on the top of the hanging cross plate 12. The nozzle on the coating nozzle 3 is located on the inner side of the material receiving frame 30 to facilitate catching the cleaned residues. A support cylinder 31 is fixedly installed on the side of the positioning plate 18 close to the inner side of the device housing 1. The slide bar 19 is rotatably installed on the inner side of the support cylinder 31 to provide support for the slide bar 19. A baffle 32 is fixedly installed on the end of the support cylinder 31 away from the positioning plate 18. The outer side of the baffle 32 contacts the inner side of the device housing 1. The size of the baffle 32 is larger than the size of the V-shaped groove on the device housing 1, which provides protection for the V-shaped groove and improves the stability of the movement of the slide bar 19.

[0029] In this embodiment: when the slider 16 moves, it can move along the inner side of the movable plate 15 and the outer side of the guide rod 29, providing support for the movement of the slider 16, preventing the movable plate 15 from tilting when driving the slider 16 to move; when the pin 20 scrapes out the residue on the inner side of the nozzle of the coating nozzle 3, the material receiving frame 30 can catch the fallen residue, which is convenient for later cleaning; the support tube 31 on the positioning plate 18 can provide support for the slide bar 19, and when the slide bar 19 moves, it can drive the baffle plate 32 to move along the inner side of the device housing 1 through the support tube 31, thereby improving the stability of the slide bar 19 when moving, and the baffle plate 32 can provide protection for the V-shaped groove on the device housing 1 to prevent overflowing coating from entering the V-shaped groove.
