Detailed Embodiments

[0034] The following will combine the attached Figures 1-4 in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment:

[0036] As Figures 1 to 4As shown in the figure, an aluminized paper double-sided dust removal device includes a dust removal chamber 11. A dust removal cavity 13 is formed in the dust removal chamber 11, and a number of driving rollers 18 for transporting aluminized paper are arranged in the dust removal cavity 13.

[0037] Openings 12 for the aluminized paper to enter and exit the dust removal cavity 13 are formed at both ends of the dust removal chamber 11. An air extraction mechanism extending into the dust removal cavity 13 is provided outside the dust removal chamber 11. The air extraction mechanism includes an air extraction vacuum pump 19, an air extraction main pipe 20, and air extraction branch pipes 21. The specific structure of the air extraction mechanism is as follows: The vacuum pump 19 is installed outside the dust removal chamber 11. The air extraction main pipe 20 is fixedly connected to the air extraction port of the vacuum pump 19. The air extraction branch pipes 21 are communicated with the air extraction main pipe 20, and the air extraction branch pipes 21 extend into the dust removal cavity 13.

[0038] A fixed dust suction hood 14 is installed on the lower side of the dust removal cavity 13. A first dust suction cavity 22 with an upward opening is formed inside the inner wall of the fixed dust suction hood 14. The first dust suction cavity 22 is communicated with the air extraction branch pipes 21. During the dust removal operation, the dust on the lower side of the aluminized paper is sucked into the air extraction branch pipes 21 through the first dust suction cavity 22. A dust collection box 16 is connected to the air outlet of the vacuum pump 19, and the sucked dust is transported into the dust collection box 16.

[0039] Moreover, a movable dust suction assembly is installed on the upper side of the installation cavity 13 to clean the dust on the upper side of the aluminized paper. The movable dust suction assembly includes a movable dust suction hood 24, a corrugated pipe 25, and a lifting assembly. The specific structure and connection method of the movable dust suction assembly are as follows: An installation frame 26 is fixedly connected to the top of the opening 12. The corrugated pipe 25 is fixedly connected to the lower end of the installation frame 26 and is communicated with the air extraction branch pipes 21.

[0040] The movable dust suction hood 24 is fixedly connected to the lower end of the corrugated pipe 25, and a second dust suction cavity 27 with a downward opening is formed inside the inner wall of the movable dust suction hood 24. When the vacuum pump 19 works, the dust on the upper side of the aluminized paper is sucked into the air extraction branch pipes 21 through the second dust suction cavity 27 and is finally collected in the dust collection box 16.

[0041] A connecting plate 28 is fixedly connected to the lower side of the corrugated pipe 25. The lifting assembly is symmetrically arranged between the connecting plate 28 and the installation frame 26. The movable dust suction hood 24 moves up and down through the lifting assembly, so that the movable dust suction hood 24 can be lifted according to the thickness of different aluminized papers and ensure that the upper pressing roller 17 always presses on the aluminized paper.

[0042] The lifting assembly includes a first sliding sleeve 29, a sliding rod 30, and a compression spring 31. The first sliding sleeve 29 is fixedly connected to the lower end of the mounting bracket 26. The sliding rod 30 is fixedly connected to the upper end of the connecting plate 28. The sliding rod 30 is movably connected within the first sliding sleeve 29. The compression spring 31 is installed between the first sliding sleeve 29 and the connecting plate 28.

[0043] When aluminized paper of different specifications passes between the lower pressing roller 15 and the upper pressing roller 17, the lower pressing roller 15 lifts upward according to the thickness of the aluminized paper, so that the aluminized paper can pass through between the lower pressing roller 15 and the upper pressing roller 17. And under the action of the compression spring 31, the upper pressing roller 17 can always press tightly on the aluminized paper.

[0044] In addition, the lower pressing roller 15 is rotatably connected within the fixed dust suction hood assembly, and the upper pressing roller 17 is rotatably connected within the movable dust suction assembly. The aluminized paper is clamped between the lower pressing roller 15 and the upper pressing roller 17, so as to ensure that the surface of the aluminized paper can be fully cleaned by the fixed dust suction hood 14 and the movable dust suction assembly.

[0045] When the aluminized paper passes between the lower pressing roller 15 and the upper pressing roller 17, the vacuum pump 19 starts to work, and makes the main air extraction pipe 20 and the air extraction branch pipe 21 generate negative pressure, so that the dust on the surface of the aluminized paper is sucked into the air extraction branch pipe 21 through the first dust suction cavity 22 and the second dust suction cavity 27, and finally is collected in the dust collection box 16, thus completing the first cleaning of the surface of the aluminized paper.

[0046] After the aluminized paper passes between the movable dust suction hood 24 and the fixed dust suction hood 14, most of the dust on its surface is sucked away, but there may still be a small amount of dust remaining on the surface of the aluminized paper. Therefore, in order to ensure that the surface of the aluminized paper is clean and dust-free and facilitate subsequent embossing processing, a secondary cleaning roller group is provided in the dust removal chamber 13 to perform secondary dust removal on the surface of the aluminized paper.

[0047] The secondary cleaning roller set includes an upper cleaning roller 32 and a lower cleaning roller 33. The specific structure and connection method of the secondary cleaning roller set are as follows: The lower cleaning roller 33 is rotatably connected to the dust removal chamber 13. A cylinder 34 is installed on the upper side of the opening 12. The end of the piston rod of the cylinder 34 is fixedly connected to a mounting seat 35. The upper cleaning roller 32 is rotatably connected to the mounting seat 35. The cylinder 34 drives the upper cleaning roller 32 to move up and down, so that the upper cleaning roller 32 can adjust its own height according to the thickness of different aluminized papers, enabling the aluminized paper to pass through between the upper cleaning roller 32 and the lower cleaning roller 33. Moreover, dust removal felts 36 are provided on both the upper cleaning roller 32 and the lower cleaning roller 33. The dust removal felts 36 can stick away the dust remaining on the surface of the aluminized paper. The dust removal felts 36 are fixed to the curved surfaces of the upper cleaning roller 32 and the lower cleaning roller 33 through Velcro (not shown in the figure), so that it is convenient for technicians to replace them when enough dust is adsorbed on the dust removal felts.

[0048] The driving mechanisms of all the rollers in this embodiment are prior arts well-known to those skilled in the art, so no more details will be given in this embodiment and the accompanying drawings of the specification.

[0049] It should be noted that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the protection scope of the present invention.

[0050] The above is only a preferred embodiment of the present invention and is 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 within the protection scope of the present invention.
