[0027] See also Figure 2 , Figure 3 and Figure 4 The first embodiment of the double-sided dust removal system for thin materials of the present invention comprises a base 1, two dust removal devices 2, and two conveying devices 6.

[0028] The base 1 includes a base body 11 and two lifting frames 12 stacked on the base body 11. Each lifting frame 12 has two frame bodies 121 spaced apart from each other.

[0029] In the first embodiment, both ends of each dust removal device 2 are connected to the frame 121 of the respective lifting frame 12, and each dust removal device 2 is movably arranged on the respective lifting frame 12, and the height of each dust removal device 2 in the vertical direction Z can be adjusted. The dust removal devices 2 are arranged at intervals up and down, and a dust removal passage 3 is formed between the dust removal devices 2 for the thin material 9 to pass through. Each dust removal device 2 includes a dust removal head 4 and a baffle unit 5.

[0030] See also Figure 5 , Figure 6 and Figure 7 Each of the dust removal heads 4 has a dust removal body 41 , a shell cover 42 , an air supply duct 43 , an exhaust duct 44 , and a plurality of shielding plates 45 .

[0031] Each of the dust removal bodies 41 extends forward and backward and has an injection chamber 411 adjacent to the dust removal passage 3, two side suction chambers 412 respectively located on the left and right sides of the injection chamber 411 and adjacent to the dust removal passage 3, a main suction chamber 413 away from the dust removal passage 3, an injection port 414 connected to the injection chamber 411 and facing the dust removal passage 3, two suction ports 415 respectively connected to the side suction chambers 412 and facing the dust removal passage 3, a plurality of side openings 416 spaced forward and backward and arranged on the left and right sides and connected to the corresponding side suction chambers 412, and a plurality of side openings 417 spaced forward and backward and arranged on the left and right sides and connected to the main suction chamber 413. In the first embodiment, the number of suction ports 415 of each of the dust removal heads 4 is two, but in other variations, the number of suction ports 415 of each of the dust removal heads 4 may also be only one.

[0032] Each of the shells 42 covers the respective dust removal body 41 and defines two suction channels 421 with the respective dust removal body 41. Each of the suction channels 421 is connected to the corresponding side suction chamber 412 and the respective main suction chamber 413, and is connected to the corresponding side opening 416 and the corresponding side opening 417.

[0033] Each of the air supply ducts 43 is connected to the injection chamber 411 and is disposed at the rear end of the respective dust removal body 41 .

[0034] Each of the exhaust air ducts 44 is connected to the main air intake chamber 413 and is disposed at the rear end of the respective dust removal body 41 .

[0035] The shielding plates 45 are respectively used to shield the side openings 417 , and the area size of each shielding plate 45 shielding the respective side opening 417 decreases as the distance between the corresponding side opening 417 and the exhaust duct 44 increases.

[0036] Each of the barrier units 5 has a plurality of barrier members 51 and a driving member 52 .

[0037] In the first embodiment, the baffles 51 are spaced apart from each other and are disposed between the respective dust removal heads 4 and the dust removal passages 3. A plurality of gaps 53 connected to the outside are formed between the baffles 51. Each of the baffles 51 has a baffle body 511, and a plurality of flanges 512 located on the outer surface of the baffle body 511 and spaced apart. Each of the baffle bodies 511 is a shaft extending forward and backward, and each of the flanges 512 is a collar sleeved on the respective baffle bodies 511. A gap 54 connected to the gap 53 is formed between each of the flanges 512 and the thin material 9. Each of the air jets 414 and each of the air intakes 415 are respectively connected to the corresponding gap 53 and the dust removal passage 3.

[0038] Each of the driving members 52 is used to drive the barrier members 51 of the respective barrier unit 5 to rotate about its own axis. In the first embodiment, the number of driving members 52 of each barrier unit 5 is one, and drives the plurality of barrier members 51 to rotate at the same time. However, in other variations, the number of driving members 52 of each barrier unit 5 may also be multiple and the same as the number of barrier members 51, and drives the barrier members 51 to rotate respectively, and the present invention is not limited thereto.

[0039] See also Figure 2 and Figure 3 The conveying devices 6 are respectively arranged on the left and right sides of the dust removal device 2 , and each of the conveying devices 6 includes a plurality of rollers 61 and a clamping shaft 62 .

[0040] The rollers 61 extend forward and backward and are spaced apart from each other and can rotate about their own axes, and are used to drive the thin material 9 to move. Each of the rollers 61 has a plurality of convex rings 611 spaced apart and sleeved on the outer surface of the rollers 61.

[0041] Each of the clamping shafts 62 extends forward and backward and is located above the corresponding roller 61 and can rotate on its own axis. Each of the clamping shafts 62 is adjacent to the dust removal channel 3 and is used to clamp the thin material 9 with the corresponding roller 61. Each of the clamping shafts 62 has a plurality of cams 621 spaced apart and sleeved on the outer surface of the clamping shaft 62. In the first embodiment, the number of the clamping shafts 62 of each of the conveying devices 6 is only one, but in other variations, the number of the clamping shafts 62 of each of the conveying devices 6 can also be adjusted to more than two according to the size of the thin material 9.

[0042] The first embodiment is suitable for connecting two air supply blowers (not shown) and two air suction blowers (not shown), the air supply blowers are respectively connected to the air supply duct 43, and the air suction blowers are respectively connected to the exhaust duct 44, so as to remove dust (not shown) on two opposite sides of the thin material 9. The steps for dust removal in the first embodiment are as follows:

[0043] First, the distance of the dust removal device 2 in the vertical direction Z can be adjusted according to the thickness of the thin material 9, that is, the height of the dust removal passage 3 can be adjusted. Next, the thin material 9 is placed on one of the conveying devices 6, and the thin material 9 is driven into the dust removal passage 3 by the rolling of the roller 61 of one of the conveying devices 6, and the thin material 9 is clamped by the clamping shaft 62 and the corresponding roller 61. During transportation, the thin material 9 will only contact the convex ring 611 of each roller 61 and the cam 621 of each clamping shaft 62, which can reduce the contact area and reduce the probability of the thin material 9 being contaminated with dust.

[0044] When the thin material 9 is transported into the dust removal passage 3, the air supply blower blows air into the jet chamber 411. Each of the air suction blowers draws air from the respective main suction chamber 413. When the air in the jet chamber 411 is ejected through the respective jet ports 414 and the dust on the two opposite sides of the thin material 9 is blown away through the gap 53 between the baffles 51, the dust can be dispersed and blown away by ultra-high-speed vibration (i.e., ultrasonic dust removal), and the dust removal effect is better. The air containing dust is attracted to the corresponding side suction chamber 412 through the suction port 415, and then enters each of the main suction chambers 413 through the corresponding suction passage 421 in sequence. At this time, each of the jet ports 414 and each of the suction ports 415 are respectively connected to the corresponding gap 53 and the dust removal passage 3, and the gap 53 is connected to the outside world, so that the air flow from the outside world can be introduced to prevent the thin material 9 from being attracted by the dust removal head 4 and deformed when passing through the dust removal passage 3. Furthermore, the gap 54 between the flange 512 of each of the baffles 51 and the thin material 9 can not only reduce the contact area between the thin material 9 and the baffles 51, but also help introduce external airflow to prevent the thin material 9 from being deformed by the suction of the dust removal head 4, so that the present invention can be applied to thin materials 9 of various materials, such as paper, optical film, copper foil or glass. In addition, the area size of each of the side openings 417 shielded by each of the shields 45 decreases as the distance between the corresponding side opening 417 and the exhaust duct 44 increases, which can maintain the suction pressure at both ends of each of the suction chambers and make the dust collection effect at both ends more consistent. Then, the dust-containing air is discharged by the suction blower through the exhaust duct 44.

[0045] Finally, the thin material 9 is driven by the other conveying device 6 and leaves the dust removal passage 3, thus completing the double-sided dust removal operation.

[0046] It is worth noting that, in the first embodiment, the driving member 52 of each of the barrier units 5 is used to drive the barrier 51 to rotate about its own axis, so that the thin material 9 can be smoothly conveyed when it contacts the barrier 51 in the dust removal passage 3. However, in other variations, the driving member 52 may be omitted from each of the barrier units 5. In addition, in the first embodiment, each of the barrier 51 is a cylinder.

[0047] The present invention forms the dust removal channel 3 between the dust removal devices 2, so that the thin material 9 can clean the two opposite sides of the thin material 9 at the same time when passing through the dust removal channel 3, thereby achieving the effect of double-sided dust removal. In addition, each of the air jets 414 and each of the air inlet 415 are respectively connected to the corresponding gap 53 and the dust removal channel 3, and the gap 53 is connected to the outside world, which can introduce the outside airflow and prevent the thin material 9 from being attracted by the dust removal head 4 and deformed when passing through the dust removal channel 3, so that the present invention is applicable to thin materials 9 of various materials and has a wide range of applications. Therefore, the purpose of the present invention can be achieved.

[0048] See also Figure 8 and Fig. 9 The second embodiment of the double-sided dust removal device 2 for thin material 9 of the present invention is substantially the same as the first embodiment, except that:

[0049] The barrier element 51' of each barrier unit 5 is a plurality of crisscrossed mesh wires, and the driving element 52 is omitted from each barrier unit 5 (see Figure 4 ), the gap 53 is formed between the baffles 51', which can also introduce external airflow to prevent the thin material 9 from being attracted by the dust removal head 4 and deformed. In this way, the second embodiment has the same purpose and effect as the first embodiment.

[0050] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
