A film 4 is installed on the surface of the two conveying rollers 3. Dust collection hoods 5 are installed on both sides of the bottom of the film 4. Through the dust collection components 13, in conjunction with filter bags 10, a negative pressure can be generated inside the dust collection box 6. Combined with branch pipes 7 and 8 and the dust collection hoods 5 on both sides of the film 4, the dust removal area of ​​the film is increased, and the dust removal effect on the film surface is improved. The dust collection box 6 is fixedly installed at the bottom of the housing 1, wherein one A branch pipe 7 is fixed between one dust hood 5 and the dust collection box 6, and a branch pipe 8 is fixed between the other dust hood 5 and the dust collection box 6. Slides 11 are fixed on both sides of the inner wall of the dust collection box 6, and a slide plate 9 is slidably mounted between the two slides 11. A filter bag 10 is mounted in the middle of the slide plate 9. A dust collection assembly 13 is installed inside the dust collection box 6. A door 12 is hinged to the surface of the dust collection box 6. By opening the door 12 and engaging the slides 11, the slide plate 9 can be easily slid off, allowing the filter bag 10 that collects dust to be disassembled and removed, reducing the difficulty of operation for users and making it more convenient to use.

[0026] The dust collection assembly 13 includes an exhaust fan 1301, which is located at the bottom inside the dust collection box 6. Support rods 1302 are fixedly installed on both sides of the exhaust fan 1301, and one end of each support rod 1302 is fixedly connected to the inner wall of the dust collection box 6. The dust collection assembly 13 also includes a ventilation mesh 1303, which is fixedly installed at the bottom of the inner wall of the dust collection box 6. The exhaust fan 1301 is installed at the bottom inside the dust collection box 6, and its two side support rods 1302 are fixedly connected to the inner wall of the dust collection box 6, providing stable support for the exhaust fan 1301. The ventilation mesh 1303 effectively exhausts air.
