A filter screen 21 and a heating plate 22 are also installed between the first suction pump 20 and the input ends of the two air supply pipes 19, and multiple groups of heaters 23 are fixedly installed on the heating plate 22.

[0030] like Figure 5 As shown, the negative pressure dust removal device 30 includes a negative pressure box 31, which is fixedly connected to the side wall of the oven 11, and the middle part of the negative pressure box 31 is hollowed out. A negative pressure box 32 protruding upward is integrally formed on the top wall of the negative pressure box 31. The negative pressure box 31 and the negative pressure box 32 are both hollow bodies. A sealing end cover 33 is hinged on the top of the negative pressure box 32. A second air suction pump 34 is installed in the cavity of the negative pressure box 32, and the output end of the second air suction pump 34 passes through the side wall of the negative pressure box 32. Air suction ports 36 are provided on the upper and lower side walls of the cavity of the hollow part of the negative pressure box 31, and first protective rubber strips 35 are fixedly installed on the end faces of both sides of the hollow part of the negative pressure box 31, and the first protective rubber strips 35 are in an arc-shaped protruding state.

[0031] like Figure 6 , Figure 7 As shown, the electrostatic dust removal device 40 includes a frame 41, which is fixedly connected to the side wall of the oven 11. The frame 41 is in a state where all four walls are hollowed out. Glass sleeves 44 are provided on the inner walls of the hollowed-out parts on the upper and lower sides of the frame 41. Servo motors 42 are fixedly installed on the front and rear side walls of the frame 41. The output end of the servo motor 42 is fixedly connected to a rotating rod 43, which extends into the corresponding hollowed-out cavities on the upper and lower sides of the frame 41. The glass sleeves 44 and the corresponding rotating rods 43 are fixedly sleeved together, and the release film passes between the upper and lower glass sleeves 44. Cover plates 45 are installed on the upper and lower side walls of the frame 41 by screws. An arc-shaped friction groove 46 is opened on the side wall of the cover plate 45 close to the corresponding glass sleeve 44. Silk cloth is installed in the friction groove 46, and the arc-shaped wall of the glass sleeve 44 is in friction contact with the silk cloth. Second protective rubber strips 47 are also fixedly mounted on the end surfaces of the left and right hollow portions of the frame 41 , and the second protective rubber strips 47 are in an arc-shaped convex state.

[0032] When in use, the release film to be dried is mounted on the conveying roller 25, one end of the release film is passed through the negative pressure dust removal device 30 and the inlet 13 into the cavity of the oven 11, the other end of the release film first passes through the second guide rod 17 on the lower side, and then passes through the first guide rod 16, and finally the other end of the release film passes through the second guide rod 17 on the upper side again, and then the other end of the release film is wound around the collecting roller 26 through the inlet and outlet 14 and the electrostatic dust removal device 40 and collected, the collecting roller 26 is driven by a motor to rotate, the working switches of the first suction pump 20 and the heater 23 are turned on, the air is sucked into the heating filter box 18 by the first suction pump 20, first filtered through the filter screen 21, and then heated by the heater 23 after filtration, and after heating, the hot air is discharged into the cavity of the oven 11 through the two air pipes 19 through the air outlet box 15, and finally the release film in the cavity of the oven 11 is dried on both sides through the air outlet pipe on the air outlet box 15. By drying the release film on both sides, the bonding between the subsequent layers of the release film is made more stable.

[0033] When the release film passes through the negative pressure dust removal device 30, the working switch of the second air suction pump 34 in the negative pressure box 32 is turned on. When the second air suction pump 34 works, negative pressure is generated in the cavities of the negative pressure box 31 and the negative pressure box 32, and the dirt and dust on both sides of the release film can be adsorbed away. The dust and dirt are sucked into the negative pressure box 32 through the air suction port 36, which can effectively remove the dust from the release film. It is worth mentioning that when the release film passes through the negative pressure box 31, the first protective rubber strip 35 can guide and protect the release film, thereby reducing damage to the release film when it passes through.

[0034] After the release film is dried, the release film enters through the entrance 14 and passes through the frame 41, and the working switches of the upper and lower servo motors 42 are turned on. When the servo motor 42 is working, it drives the rotating rod 43 to rotate. When the rotating rod 43 rotates, it drives the corresponding glass sleeve 44 to rotate. When the glass sleeve 44 rotates continuously, it rubs against the silk cloth in the corresponding friction groove 46, so that static electricity is generated on the glass sleeve 44, so that the release film passing between the upper and lower glass sleeves 44 can be effectively electrostatically dusted, and the fine dust and dirt on the surface of the release film can be adsorbed by static electricity, thereby improving the production and processing quality of the release film. It is worth mentioning that the rotation of the two glass sleeves 44 will not produce resistance to the release film, and the two glass sleeves 44 may not contact the passing release film. Similarly, the second protective rubber strip 47 is also set to guide and protect the release film, reducing the damage of the release film during transportation.
