A receiving cavity 5 is opened at the bottom of the strip-shaped rod 4. In the middle of the inner cavity of the receiving cavity 5, two partition plates 6 are symmetrically installed. On one side of the two partition plates 6 away from each other, there are moving blocks 7. It further includes: a transmission assembly 12 arranged between the partition plates 6 and capable of driving the moving blocks 7 to slide along the inner wall of the receiving cavity 5. At the bottom of the moving block 7, a first support plate 8 is fixedly connected. At the bottom of the end of the first support plate 8 away from the moving block 7, a fixed block 9 is fixedly connected. At the bottom of the fixed block 9, a second support plate 10 is fixedly connected. On the outside of the second support plate 10, there is a U-shaped plate 15. On one side of the U-shaped plate 15, there is a blowing pipe 11. By setting the transmission assembly 12, it is convenient for the staff to quickly adjust the distance between the two blowing pipes 11 according to the actual size of the film; on the outside of the blowing pipe 11, there is a blowing assembly 16 capable of preventing the edges of the film from curling up. By setting the blowing assembly 16, it can prevent the edges of the film from curling up by blowing instead of manual labor, thus ensuring the processing quality and effect of the film; a first adjustment assembly 13 is arranged on one side of the U-shaped plate 15 and is convenient for adjusting the distance between the blowing pipe 11 and the film. By setting the first adjustment assembly 13, it is convenient for the staff to quickly adjust the distance between the blowing pipe 11 and the film according to the actual situation of film preparation, thus improving the anti-curling effect; on the other side of the U-shaped plate 15, there is a second adjustment assembly 14 convenient for adjusting the air outlet angle of the blowing pipe 11. By setting the second adjustment assembly 14, it is convenient for the staff to quickly adjust the angle of the blowing pipe 11 facing the film according to the actual situation of film preparation. Combined with the first adjustment assembly 13, the anti-curling effect can be further improved; above the strip-shaped rod 4, there is a top plate 17. The top plate 17 is respectively connected to the second side plates 3 at both ends. On one side of the first side plate 2, there is a third adjustment assembly 19 convenient for adjusting the height of the blowing pipe 11.

The purging pipe 11 can be driven by the connecting rod 146 and the mounting seat 143 to rotate around the circular boss 141. In this way, it is convenient for the staff to quickly adjust the air outlet angle of the purging pipe 11 according to the actual situation of film preparation. Cooperating with the first adjustment component 13 can further improve the anti-curling effect.

[0029] The third adjustment component 19 includes a third support plate 192 fixed to one side of the first side plate 2. A lifting oil cylinder 191 is fixedly installed on the top of the third support plate 192. The top end of the lifting oil cylinder 191 is connected to the top plate 17, as Figure 1 , Figure 2 shown. The purging pipe 11 is driven by the lifting oil cylinder 191 to approach or move away from the film, so as to adjust the purging component 16 in place, facilitating the subsequent anti-curling work.

[0030] The limiting component 18 includes a limiting block 181 fixedly connected to one side of the second side plate 3. A limiting groove 182 corresponding to the limiting block 181 is formed on one side of the first side plate 2. The limiting block 181 is located inside the limiting groove 182, as Figure 1 , Figure 2 shown. It prevents the second side plate 3 from detaching from the first side plate 2, and at the same time makes the lifting displacement of the purging pipe 11 smoother, improving the stability of the structure.

[0031] Working principle: First, the staff installs the present utility model at a suitable position on the film preparation process line. Then, the purging component 16 is adjusted in place through the third adjustment component 19. Next, the distance between the two purging pipes 11 is adjusted according to the actual size of the film through the transmission component 12. The distance between the purging pipe 11 and the film is adjusted through the first adjustment component 13. Then, the air outlet angle of the purging pipe 11 is quickly adjusted in cooperation with the second adjustment component 14. In this way, the operation process of the anti-curling device is simplified, and the operation difficulty of the anti-curling device is reduced. After the purging component 16 is adjusted, a high-speed airflow is blown out through the purging component 16 to prevent the edges of the film from curling up, ensuring the processing quality and processing effect of the film.
