[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figures 1 to 3 , a film cutting and dust removal device 100 of the present utility model is used to remove the dust generated during cutting after the film 300 is cut by the cutting knife 200. Therefore, along the moving direction of the film 300 ( Figure 1 arrow direction), the film cutting and dust removal device 100 is located behind the cutting knife 200, and the film 300 first passes through the cutting of the cutting knife 200, and the cut film 300 moves to the film cutting and dust removal device 100 for dust removal.

[0024] The film cutting and dust removal device 100 includes a lower suction nozzle 10, an upper suction nozzle 20, a detection device 40, a connection block 50, a negative pressure pipe 60, a lifting drive structure 70, a negative pressure generating device, a filter screen and a dust collection bag. The lower suction nozzle 10 and the upper suction nozzle 20 are arranged at intervals so as to form a channel for the edge of the film 300 to move between the lower suction nozzle 10 and the upper suction nozzle 20.

[0025] Specifically, both the lower suction nozzle 10 and the upper suction nozzle 20 are in the shape of a cuboid. A plurality of suction openings 30 are provided on the lower surface of the lower suction nozzle 10 and the upper surface of the upper suction nozzle 20, and the plurality of suction openings 30 are evenly arranged. The positions of the plurality of suction openings 30 on the lower surface of the lower suction nozzle 10 and the upper surface of the upper suction nozzle 20 correspond to each other one by one.

[0026] Since the thin film 300 has a planar structure, the lower surface of the lower suction nozzle 10 and the upper surface of the upper suction nozzle 20 are both planar and parallel to each other. A plurality of air channels are provided inside the lower suction nozzle 10 and the upper suction nozzle 20 or they are hollow structures, so that each air suction port 30 is communicated with a negative pressure generating device, and the air suction port 30 can form a negative pressure to suck air and dust on the surface of the thin film 300.

[0027] The detection device 40 is installed on the lower suction nozzle 10 and / or the upper suction nozzle 20, and is used to detect the distance between the thin film 300 and the air suction port 30, so as to adjust the position of the air suction port 30. In the case where the thin film 300 shakes and the tension of the thin film 300 is unstable, the lower suction nozzle 10 and the upper suction nozzle 20 can be driven to move in the vertical direction by the lifting drive structure 70, ensuring that the lower suction nozzle 10 and the upper suction nozzle 20 do not contact the thin film 300, generating friction and generating new dust.

[0028] Specifically, in this embodiment, the number of the detection devices 40 is two, and the two detection devices 40 are respectively installed on the lower suction nozzle 10 and the upper suction nozzle 20. The detection device 40 and the air suction port 30 are located on the same plane. The detection device 40 is a photoelectric sensor.

[0029] The connecting block 50 is fixed to the lower suction nozzle 10 and the upper suction nozzle 20. The connecting block 50 is located at the end of the channel, and the width of the channel is 5 - 10 cm. The connecting block 50 is provided with an air channel inside or is a hollow structure, and the air suction port 30 is communicated with the negative pressure generating device through the connecting block 50.

[0030] The negative pressure pipe 60 is connected to the connecting block 50. The lower suction nozzle 10 and the upper suction nozzle 20 are communicated with the negative pressure generator through the connecting block 50 and the negative pressure pipe 60. The air outlet of the negative pressure generator is connected to a dust collection bag, and the dust collection bag and the external environment are filtered through a filter screen.

[0031] The lifting drive structure 70 is any one of a cylinder, a linear module, and a lead screw. In this embodiment, the lifting drive structure 70 is a cylinder. Specifically, the lifting drive structure 70 includes a mounting plate 71, a driving body 72, a push rod 73, and a fixing plate 74. The driving body 72 is fixed to the mounting plate 71. One end of the push rod 73 is installed on the driving body 72, and the other end of the push rod 73 is fixedly connected to the fixing plate 74. The fixing plate 74 is fixedly connected to the connecting block 50. The extending direction of the push rod 73 is the vertical direction. The push rod 73 of the lifting drive structure 70 drives the connecting block 50 to move in the vertical direction, adjusting the distance between the air suction port 30 and the thin film 300, which can prevent the dust generated by the cutting of the thin film 300 from not being sucked away by the suction nozzle due to a large distance; and can also prevent the thin film 300 from being sucked onto the suction nozzle due to a small distance, causing scratches on the thin film 300 and generating new dust.

[0032] When using a film cutting and dust removal device 100, dust is sucked through the lower suction nozzle 10 and the upper suction nozzle 20, which can effectively eliminate the dust particles dispersed in the workshop air after the film 300 is trimmed and the dust particles remaining on the surface of the film 300. That is, it can reduce the amount of dust in the air, thereby improving the cleanliness level of the dust-free workshop and increasing the service life of the high-efficiency filter in the dust-free workshop; it can also effectively eliminate the dust within 0-8 mm at both ends of the mother roll of the film 300, which causes product degradation, and improve the product yield; it can also collect the dust particles generated by trimming through the collection bag and recycle the collected dust particles by regranulation.

[0033] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the substantial technology of the present invention, and these all belong to the protection scope of the present invention.
