[0044] In the embodiment, when the film piece 12 is conveyed from the supporting roller 10 to the traction conveying roller assembly 37, it first needs to pass through the wiping of the two dust wiping cotton blocks 30 arranged above and below to wipe off the dust falling on the surface of the film piece 12, and then needs to pass through the dust scraping of the two groups of rubber dust scraping plates 34 arranged inwards to scrape off the adsorbed dust. At the same time, the film piece 12 is lifted up under the lifting action of the rubber separation top abutting plate piece 36, and the position of the film piece 12 being lifted up is referred to as a convex shape structure, so that the film piece 12 can increase the friction force between the opposite rubber dust scraping plates 34, thereby improving the dust removal effect and applying force to scrape off the dust particles adsorbed on the surface of the film piece 12, thereby improving the dust removal effect. At the same time, the tip part of the rubber separation top abutting plate piece 36 can further scrape dust.

The L-shaped support vertical plate 20 does not need to be moved under the normal conveying and winding dust removal of the film piece 12. Only when the film piece 12 is not moving, the electric push-pull rod 29 can be started to drive the L-shaped support vertical plate 20 to move linearly and reciprocally to realize the dust removal and cleaning of the film piece 12.

[0051] In the embodiment, the middle position of the upper part of each fixed vertical plate 2 is provided with a lifting stroke groove 14, each lifting stroke groove 14 is longitudinally and slidingly connected with a lifting block 3, the top surface of the fixed vertical plate 2 is threadedly penetrated and connected with a rotating lifting shaft 4 towards the lifting stroke groove 14, and the bottom light pole end of the rotating lifting shaft 4 is connected with the lifting block 3 through a bearing. When the rotating lifting shaft 4 is screwed, the lifting block 3 is driven to move longitudinally in the lifting stroke groove 14 under the action of the bearing, so as to adjust the height of the conveying upper roller 5. By adjusting the position of the lifting block 3, the height of the conveying upper roller 5 can be adjusted to adapt to the film piece 12 with different thicknesses or widths. The rotating lifting shaft 4 is used to drive the lifting block 3 to move up and down.

[0052] In this embodiment, the traction conveying roller assembly 37 includes a conveying upper roller 5 rotatably mounted between the two lifting blocks 3 and a conveying lower roller 11 rotatably mounted between the two fixed vertical plates 2, and the film piece 12 is output from between the conveying upper roller 5 and the conveying lower roller 11.

The motor 7 is fixed at the bottom of the film auxiliary winding moving table 1, the output shaft of the motor 7 is interference-fitted with the driving wheel 17, and the driven wheel 16 and the driving wheel 17 are connected through the belt 18. The bottom wall of the film auxiliary winding moving table 1 is provided with a power distribution operation box (not shown in the figure), and the power distribution operation box is provided with a PLC for controlling the opening and closing of the above electronic device structure. The type of the PLC should be selected according to the actual installation site. The upper visual recognition CCD camera 32 and the lower visual recognition CCD camera 19 are connected with the PLC through wired or wireless mode.

[0053] Working principle:

[0054] The film production is used for an online dust removal device. The film piece 12 is output from the end of the production line, enters the film auxiliary winding moving table 1 through the supporting roller 10, the motor 7 drives the driving wheel 17, the driving wheel 17 drives the driven wheel 16 to rotate through the belt 18, and then drives the driving shaft 15 and the conveying lower roller 11 to rotate, together with the conveying upper roller 5 to constitute the traction conveying roller assembly 37, and jointly act on the film piece 12 to convey it forward smoothly.

[0055] According to the film piece 12 with different thicknesses, the position of the lifting block 3 can be adjusted by screwing the rotating lifting shaft 4, so as to change the height of the conveying upper roller 5, so as to ensure the appropriate pressing force and maintain the tension and flatness of the film piece 12.

[0056] After the film piece 12 passes through the supporting roller 10, it first contacts the dust removal wiping cotton block 30, which preliminarily cleans the film surface and removes larger particles. Then, the film piece 12 passes through the rubber dust scraping plate 34, which further removes the dust attached to the film by using the dust scraping tip 35. The rubber partition top abutting plate piece 36 is located between the two groups of rubber dust scraping plates 34, which can lift the film piece 12 to form a convex shape, increase the contact pressure between the film and the rubber dust scraping plate 34, and improve the dust removal efficiency.

[0057] After the film piece 12 is cleaned, it continues to move forward, and the upper visual recognition CCD camera 32 and the lower visual recognition CCD camera 19 arranged above and below monitor the surface of the film piece 12 in real time, checking whether there are residual dirt or parts that are not cleaned. If the detected dust particles exceed the preset value, the system will issue an alarm to prompt the operator to replace or clean the dust removal assembly 13; if the detection result is good, it indicates that the film piece 12 has reached the quality requirement. After the above processing, the clean and flat film piece 12 is finally sent to the winding equipment by the traction conveying roller assembly 37 for collection and arrangement.
