In the first embodiment, the barrier members 51 are spaced left and right and are disposed between the respective cleaning heads 4 and the cleaning channels 3.

Each of the clamping shafts 62 has a plurality of cams 621 that are disposed on the outer surface of the clamping shaft 62 at intervals. In the first embodiment, the number of the clamp shafts 62 of each of the transport devices 6 is only one, but in other variations, the number of the clamp shafts 62 of each of the transport devices 6 may be adjusted to two or more depending on the size of the sheet material 9.
The first embodiment is adapted to connect two air supply blowers (not shown) respectively connected to the air supply duct 43 and two air suction blowers (not shown) respectively connected to the air discharge duct 44 to remove dust (not shown) on opposite sides of the thin material 9. The steps for removing dust in this first embodiment are as follows:
first, the distance of the dust removing device 2 in the up-down direction Z, that is, the height of the dust removing channel 3 may be adjusted according to the thickness of the thin material 9. Then, the thin material 9 is placed on one of the conveying devices 6, the roller 61 of one of the conveying devices 6 rolls to drive the thin material 9 to enter the dust removing channel 3, and the clamping shaft 62 and the corresponding roller 61 clamp the thin material 9. During the transportation, the thin material 9 only contacts the convex ring 611 of each roller 61 and the cam 621 of each clamping shaft 62, so that the contact area can be reduced and the probability of dust contamination of the thin material 9 can be reduced.
When the thin material 9 is conveyed into the dust removal passage 3, the air supply blower blows air into the air ejection chamber 411. Each of the suction blowers draws air in a respective main suction chamber 413. When the air in the air injection chamber 411 is injected through the respective air injection ports 414 and blows off the dust on the two opposite sides of the thin material 9 through the gaps 53 between the blocking members 51, the dust can be scattered and sprayed away in a super-high speed vibration (i.e. ultrasonic dust removal) manner, the dust removal effect is better, and the air containing the dust is sucked into the corresponding side air suction chamber 412 through the air suction port 415 and then sequentially enters each main air suction chamber 413 through the corresponding air suction channel 421. At this time, each of the air outlets 414 and the air inlets 415 are respectively communicated with the corresponding gap 53 and the dust removing channel 3, and the gap 53 is communicated with the outside, so that the external air flow can be introduced to prevent the thin material 9 from being sucked by the dust removing head 4 and deformed when passing through the dust removing channel 3. And through the gap 54 between the flange 512 of each barrier 51 and the thin material 9, the contact area between the thin material 9 and the barrier 51 can be reduced, and the external air flow can be guided to avoid the deformation of the thin material 9 due to the suction of the dust removing head 4, so that the invention can be applied to the thin materials 9 made of various materials, such as paper, optical films, copper foils or glass. In addition, the area size of each of the shutters 45 covering the respective side opening 417 is reduced as the distance between the corresponding side opening 417 and the exhaust duct 44 is increased, so that the suction pressure at both ends in each of the suction chambers can be maintained and the dust suction effect at both ends can be more uniform. Then, the air containing dust is discharged by the suction blower through the exhaust air duct 44.
Finally, the thin material 9 is driven by the other conveying device 6 and leaves the dust removing channel 3, and the double-sided dust removing operation is completed.
It should be noted that, in the first embodiment, the driving member 52 of each of the blocking units 5 is used to drive the blocking member 51 to rotate along its own axis, so that the thin material 9 can be smoothly conveyed in the dust removing channel 3 if contacting the blocking member 51. In other variants, however, the drive element 52 can also be omitted for each of the blocking units 5. Further, in the present first embodiment, each of the stoppers 51 is a cylinder.
In the invention, the dust removing channel 3 is formed between the dust removing devices 2, so that two opposite sides of the thin material 9 can be cleaned simultaneously when the thin material 9 passes through the dust removing channel 3, and the effect of double-sided dust removal is achieved, in addition, each air jet 414 and each air suction port 415 are respectively communicated with the corresponding gap 53 and the dust removing channel 3, and the gap 53 is communicated with the outside, and the external air flow can be introduced to avoid the thin material 9 from being sucked by the dust removing head 4 and deformed when the thin material 9 passes through the dust removing channel 3, so that the invention is suitable for thin materials 9 of various materials, and has a wider application range. Therefore, the object of the present invention can be achieved.
Referring to fig. 8 and 9, the second embodiment of the double-sided dust removing device 2 for the thin material 9 of the present invention is substantially the same as the first embodiment, except that:
the barrier pieces 51 'of each barrier unit 5 are a plurality of criss-cross mesh wires, the driving pieces 52 (see fig. 4) are omitted from each barrier unit 5, the gaps 53 are formed between the barrier pieces 51', and external air flow can be introduced to prevent the thin material 9 from being attracted by the dust removing head 4 and deformed. Therefore, the second embodiment has the same purpose and efficacy as the first embodiment.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
