Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The dust collection cylinder 22 is installed at the front end of the housing 9, and the negative pressure fan 23 is installed and fixed inside the rear end of the housing 9.

[0027] The right side of the connecting pipe 8 passes through the interior of the front end of the casing 9 and is fixedly connected to the front end of the dust collection cylinder 22. The bottom end of the corrugated pipe 7 is fixedly connected to the top end of the bottom pipe 6. The threaded inner hole 26 passes through the interior of the left side of the bottom pipe 6. The locking rod 25 is threadedly rotatably connected in the threaded inner hole 26.

[0028] Specifically, such as Figures 1-3As shown, during the internal spraying process of the membrane material introduction mechanism, the negative pressure fan 23 can be started to generate negative pressure inside the machine box 9. The suction hood 5 can be used to perform auxiliary suction pre-cleaning of some dust and other debris on the surface of the membrane material that is conveyed into the top frame 2, thereby improving the cleanliness of the membrane material surface. The dust and debris that are sucked up can be guided into the dust collection cylinder 22 for collection by the bottom pipe 6, the corrugated pipe 7 and the connecting pipe 8. At the same time, when suctioning and removing dust, the bottom pipe 6 can be unlocked by turning the locking rod 25 to the left.

The top ends of the two sets of limiting slide rods 27 pass through the inside of the top of the mounting frame 19.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, after the membrane material is conveyed into the interior of the top frame 2, it passes between the lower rotating roller 20 and the upper rotating roller 30. The lower rotating roller 20 and the upper rotating roller 30 can be used to assist in flattening the surface of the membrane material. The pressure can also be adjusted by rotating the drive rod 28 to adjust the upper position of the upper rotating roller 30.

[0031] A top plate 17 is fixed to the top of the liquid distribution seat 15, and guide rods 10 are fixed to the four corners of the top of the top plate 17. A threaded sleeve 12 is movably connected to the middle position of the bottom of the mounting seat 18, and a worm gear 14 is fixed to the outside of the threaded sleeve 12. A threaded stud 11 is threadedly connected to the inside of the threaded sleeve 12. The bottom end of the threaded stud 11 passes through the inside of the bottom of the mounting seat 18 and is movably connected to the top of the top plate 17. The top ends of the four sets of guide rods 10 pass through the inside of the bottom of the mounting seat 18. A servo motor 24 is fixedly installed on the right side of the rear end of the mounting seat 18. A worm gear 13 is movably installed on the right side of the bottom of the mounting seat 18. The worm gear 13 is meshed with the worm gear 14. The output shaft of the servo motor 24 is fixedly connected to the rear end of the worm gear 13. A limit plate is fixed to the top of the threaded stud 11.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the servo motor 24 can be controlled to start and drive the worm gear 13 to rotate. When the worm gear 13 rotates, the meshing worm wheel 14 can drive the threaded sleeve 12 to rotate. When the threaded sleeve 12 rotates, it can drive the threaded column 11 to move downward, and at the same time push the liquid distribution seat 15 and the nozzle 16 to move downward. By adjusting the spraying distance between the nozzle 16 and the film material, the spraying thickness of the coating on the surface of the film material can be easily adjusted.

[0033] Side frames 21 are fixed to the bottom ends of both sides of the top frame 2, and conveying rollers 4 are movably connected to the top of the side frames 21. Mounting frames 19 are opened inside both sides of the top frame 2. Several nozzles 16 are installed at equal intervals at the bottom of the liquid distribution seat 15. A lower rotating roller 20 is hinged to the front end of the top frame 2.

[0034] Working Principle: During the spraying process inside the membrane material introduction mechanism, the negative pressure fan 23 can be activated to create negative pressure inside the casing 9. The suction hood 5 can then assist in pre-cleaning the surface of the membrane material, removing dust and other debris, improving its cleanliness and facilitating the coating application. The extracted dust and debris are collected in the dust collection cylinder 22 via the bottom pipe 6, corrugated pipe 7, and connecting pipe 8. After the membrane material enters the top frame 2, it passes between the lower roller 20 and the upper roller 30. The lower roller 20 and upper roller 30 assist in flattening the membrane surface. The pressure can be adjusted by rotating the drive rod 28 to change the upper position of the upper roller 30. After the membrane material moves past the bottom of the liquid distribution seat 15, multiple nozzles 16 at the bottom can be used to spray a nano-cellulose coating onto the membrane surface. During the spraying process, the servo motor 24 can be controlled to start and drive the worm gear 13 to rotate. The rotation of the worm gear 13 can drive the threaded sleeve 12 to rotate through the meshing worm wheel 14. The rotation of the threaded sleeve 12 can drive the threaded column 11 to move downward, and at the same time push the liquid distribution seat 15 and the spray head 16 to move downward. By adjusting the spraying distance between the spray head 16 and the film material, the spraying thickness of the coating on the surface of the film material can be adjusted.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
