[0029] like Figure 1 and Figure 2 As shown, the film dust removal device includes a conductive body 20, and a conductive top cover 30 is installed on the top of the body 20, such as... Figure 4 As described above, a recessed groove 26 is provided at the top of the main body 20, such as... Figure 3 As shown, the bottom of the top cover 30 has an upper recessed groove 35, and the upper recessed groove 35 and the lower recessed groove 26 form a channel for the film to pass through, as shown. Figure 2 As shown, a lower conductive cotton 21 is installed at the inlet end of the lower recess 26, and the lower conductive cotton 21 contacts the bottom surface of the film. An upper conductive cotton 31 is installed at the inlet end of the upper recess 35, and the upper conductive cotton 31 contacts the top surface of the film. Further, as... Figure 1 and Figure 2 As shown, a bottom cover 10 is also installed at the bottom of the main body 20, such as... Figure 6 and Figure 7 As shown, the bottom cover 10 has an air inlet 11 and an air outlet 12, as... Figure 5 As shown, a wind cavity 41 is provided at the bottom of the main body 20, and a fan (not shown in the figure) is installed inside the wind cavity 41. Figure 2 and 3 As shown, the bottom of the top cover 30 has an upper air outlet 33 that communicates with the air cavity 41, such as... Figure 2 , Figure 4 and Figure 5As shown, the top of the main body 20 has a lower air outlet 23 that communicates with the air cavity 41. The upper air outlet 33 is located above the film, and the lower air outlet 23 is located below the film. During installation, the bottom cover 10 is installed on a conductive base plate, which is grounded. Therefore, the top cover 30, the main body 20, and the bottom cover 10 are grounded, which in turn makes the conductive cotton grounded. When the film passes through the upper conductive cotton 31 and the lower conductive cotton 21, the static electricity on the film is conducted through the conductive cotton, thereby eliminating the static electricity on the film. The conductive cotton also has the function of wiping away dust on the film. Therefore, when the film passes through the conductive cotton, the static electricity on the film is eliminated, and most of the dust is wiped away. Even if there is still dust on the film, it will be removed because the static electricity on the film has been eliminated. Afterwards, dust will not be attracted to the film due to static electricity. Therefore, the dust on the film can be blown away by the wind. That is to say, after the film passes through the conductive cotton, the fan is in working condition. The upper air outlet 33 blows air onto the top surface of the film, and the lower air outlet 23 blows air onto the bottom surface of the film, thereby blowing away the dust on the film. In this embodiment, the top cover 30 is provided with an upper dust outlet 32, which is located between the upper air outlet 33 and the upper conductive cotton 31. The main body 20 is provided with a lower dust outlet 22, which is located between the lower air outlet 23 and the lower conductive cotton 21. The dust blown up is discharged through the upper dust outlet and the lower dust outlet 22, so that the film entering the film holder is free of static electricity and dust, thereby improving the reliability of film copying.

[0030] In this embodiment, as Figure 2 As shown, the upper sinking groove 35 has an upper inlet groove 37 at its inlet end, which is located in front of the upper conductive cotton 31. The lower sinking groove 26 has a lower inlet groove 28 at its inlet end, which is located in front of the lower conductive cotton 21. During the film feeding process, the conductive cotton wipes away the dust on the film, and some of it falls into the inlet groove. In particular, most of the dust on the bottom surface of the film falls into the inlet groove, which facilitates the collection and removal of dust. Moreover, in this embodiment, the inlet grooves all have slopes, which are close to the conductive cotton. The upper inlet groove 37 and the lower inlet groove 28 form an outward opening, which facilitates the installation and feeding of the film.

[0031] In this embodiment, as Figure 5As shown, ventilation channels 24 are provided on both sides of the air cavity 41, and the lower air outlet 23 is located between the two ventilation channels 24. The air outlet of the ventilation channel 24 is connected to the upper air outlet 33. When the fan is working, the fan generates suction on the bottom cover 10, and the outside air enters the air cavity 41 through the air inlet 11 and the air outlet. Then, the fan blows a portion of the air through the lower air outlet 23. The lower air outlet 23 is aimed at the bottom surface of the film, and blows air onto the bottom surface of the film, thereby blowing away the film. One part of the air blows away the dust on the top surface of the film, while another part of the air enters the upper air outlet 33 through the ventilation channel 24. The upper air outlet 33 is aimed at the top surface of the film, and blows air onto the top surface of the film to remove the dust. In this embodiment, a labyrinth groove is provided at the bottom of the top cover 30, which forms the upper air outlet 33. Furthermore, the labyrinth groove spans the left and right sides of the film, thereby improving the reliability of the dust on the top surface of the film being blown away. Moreover, there are three lower air outlets 23, which are spaced apart in the longitudinal direction.

[0032] In this embodiment, as Figure 6 and Figure 7 As shown, the bottom cover 10 has a cavity, with a hollow air outlet 12 formed at the top of the cavity and a grid-shaped air inlet 11 formed at the bottom of the cavity. The cavity is filled with filter cotton (not shown in the figure). Preferably, one side wall of the cavity is open, forming a side air inlet 13, which facilitates the filling of filter cotton. When the fan is working, the air is filtered by the filter cotton and enters the air cavity 41 through the air outlet 12, thereby ensuring the cleanliness of the fresh air and ensuring the reliability of the film dust removal.

[0033] In this embodiment, as Figure 2 and Figure 3 As shown, an upper dust removal cotton 34 is installed at the film outlet end of the upper sink 35. The upper dust removal cotton 34 is located behind the upper air outlet 33, and the upper dust removal cotton 34 is in contact with the top surface of the film. Figure 2 and Figure 5 As shown, a lower dust removal cotton 25 is installed at the film outlet end of the sink trough 26. The lower dust removal cotton 25 is located behind the lower air outlet 23 and is in contact with the bottom surface of the film. After the dust on the film is blown away by the wind, in order to further improve the dust removal rate on the film, the dust removal cotton wipes away the dust on the film again. The dust wiped away by the dust removal cotton is discharged by the wind blown out by the upper air outlet 33 and the lower air outlet 23, and finally discharged through the corresponding dust outlet.

[0034] In this embodiment, as Figure 2 and Figure 4 As shown, an upper dust collection trough 38 is provided on the upper settling trough 35. The upper dust collection trough 38 is located between the upper dust collection cotton 34 and the upper air outlet 33, as shown. Figure 2 and Figure 5As shown, a lower dust removal groove 29 is provided on the sink trough 26. The lower dust removal groove 29 is located between the lower dust removal cotton 25 and the lower air outlet 23. Preferably, the dust removal grooves all have slopes, which are close to the dust removal cotton. The upper dust removal groove 38 and the lower dust removal groove 29 form outward openings, which facilitates the installation and feeding of the film. At the same time, the dust removal grooves also have the function of accommodating wind force, which facilitates the dust being rolled up from the edge of the dust removal cotton. In this embodiment, the dust removal cotton can be ordinary sponge. Preferably, it is light-blocking cotton. Although the film and sponge will rub against each other when the film passes through the light-blocking cotton, thus generating an electric charge, since the main body 20 is conductive, the film will come into contact with the main body 20 after passing through the light-blocking cotton. Since the main body 20 is conductive and grounded, the charge on the film will also be eliminated. Of course, in this embodiment, the dust removal cotton can also be conductive cotton.

[0035] In this embodiment, as Figure 3 and Figure 4 As shown, the main body 20 located on the left and right sides of the sinking trough 26 has slots 36, and the top cover 30 located on the left and right sides of the upper sinking trough 35 has a locking block 27 that matches the slot 36. The locking block 27 is locked in the slot 36, so the main body 20 and the top cover 30 can be well positioned during assembly, which facilitates installation.

[0036] The working process of this utility model is as follows: After assembling the bottom cover 10, the main body 20 and the top cover 30, the bottom cover 10 is placed on a conductive base plate, which is grounded. Therefore, the bottom cover 10, the main body 20 and the top cover 30 are all grounded. Then, the end of the film is inserted into the inlet groove and passes through conductive cotton and dust removal cotton in sequence, and finally exits from the end of the channel. Then, the fan is turned on, and the film is pulled by the traction mechanism. Of course, the film can be pulled manually. In this embodiment, when the film dust removal device is used in conjunction with the film copying clip, the film can be pulled directly by the traction mechanism on the film copying clip. During the film pulling process, the film eliminates static electricity and is dusted once through the conductive cotton, then is dusted a second time through the blower, and finally is dusted a third time through the dust removal cotton, thereby improving the dust removal efficiency of the film and improving the reliability of film copying.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
