This is a well-known technical method and will not be described in detail here.

[0027] A heating cover 7 is installed on the top surface of the baffle 1. A known electric heating wire structure is fixedly connected to the inner surface of the heating cover 7 to generate heat. An exhaust fan 8 draws air and blows it into the heating cover 7 to form hot air, which dries and heats the release agent on the film. An exhaust fan 8 is fixedly connected to the air inlet of the heating cover 7 through a hose. A filter box 9 is fixedly connected to the end of the exhaust fan 8 away from the heating cover 7. A filter screen 20 is fixedly embedded in the front surface of the filter box 9. When the exhaust fan 8 is started, the air enters the heating cover 7 after being filtered by the filter screen 20. A brush layer 21 is fixedly connected to the rear surface of the dust collection box 11. The brush layer 21 is slidably connected to the filter screen 20. A clip box 23 is fixedly embedded in the front surface of the filter box 9. A second sliding block 24 is fixedly connected to the front surface of the dust collection box 23. A groove matching the structural dimensions of the second sliding block 24 is opened on the front surface of the dust collection box 11. When the dust collection box 11 moves up and down, the second sliding block 24 slides in the groove of the groove, improving the stability of the movement of the dust collection box 11. A guide rail mechanism 10 is provided on the front surface of the filter box 9. The dust collection box 11 is provided on the front side of the filter box 9. A dust collection box 12 is provided on one side of the dust collection box 11. A dust filter box 13 is fixedly connected to one side surface of the dust collection box 12.

The dust filter plate is a known filter structure that filters dust and prevents dust from damaging the dust pump 14. A dust pump 14 is fixedly connected to one side surface of the dust filter box 13.

[0028] like Figure 4 As shown, the guide rail mechanism 10 includes a guide rail box 101 that is fixedly connected to the front surface of the filter box 9. The inner cavity of the guide rail box 101 is provided with a threaded rod 102. A servo motor 103 is fixedly connected to the top of the guide rail box 101. The top of the threaded rod 102 is fixedly connected to the output end of the servo motor 103. The bottom end of the threaded rod 102 is movably connected to the guide rail box 101 through a bearing. When the servo motor 103 is started, it drives the threaded rod 102 to rotate. A first sliding block 22 is fixedly connected to the rear surface of the dust collection box 11. The first sliding block 22 is threadedly connected to the outer surface of the threaded rod 102. A groove matching the structural size of the first sliding block 22 is opened on the front surface of the guide rail box 101. As the threaded rod 102 rotates forward and backward, the first sliding block 22 and the dust collection box 11 assembly move up and down.

[0029] Working principle: During use, place the device in a suitable position and place the film to be coated with the release agent on the surface of the conveyor 2. The pressure roller under the support plate 15 assists in the movement of the film. If the width of the film is large, open the switch valves on the outside of the two liquid outlet ends of the three-way pipe 43. This controls the start of the suction pump 41 and the coating motor 19. The suction pump 41 draws the paste-like release agent from the storage tank 3 through the suction pipe 42 and discharges it through the three-way pipe 43 into the first coating tank 5 and the second coating tank 6. The start of the coating motor 19 drives the coating roller 18 to rotate, coating the paste-like release agent onto the surface of the film. After the release agent is applied, the film moves to below the heating hood 7. When the exhaust fan 8 starts, air passes through... After filtration by the filter screen 20, the filter screen enters the heating hood 7. The electric heating wire in the heating hood 7 generates heat to form hot air, which dries and heats the release agent on the film. Furthermore, when it is necessary to clean the filter screen 20, the exhaust fan 8 is turned off, and the servo motor 103 and the dust pump 14 are started. The start of the servo motor 103 drives the rotation of the threaded rod 102. As the threaded rod 102 rotates forward and backward, the first sliding block 22 and the dust collection box 11 assembly move up and down. At this time, the brush layer 21 on the dust collection box 11 brushes and cleans the filter screen 20. The start of the dust pump 14 causes the dust collection box 12 to generate suction, sucking the brushed dust into the dust collection box 12.
