The first collecting box 320 is provided with a material receiving trough with an opening facing upward. 321, two purging mechanisms are arranged on the top inner wall of the material blocking hood 310, and the two purging mechanisms are respectively located on the left and right sides of the production line 400, and the purging mechanisms include a first blower 330 and a main air pipe 340, the first blower 330 is installed on the material blocking hood 310, and an air inlet is arranged on the upper surface of the main air pipe 340, and an air outlet end of the first blower 330 is connected to the air inlet through a pipeline, and a plurality of air nozzles 350 are arranged on the lower surface of the main air pipe 340, and the air nozzles 350 face the production line 400.
[0031] Specifically, the film blowing system provided in the embodiment of the utility model uses the air nozzle 350 to quickly blow the tailings on the production line 400 into the receiving troughs 321 on both sides of the production line 400 to complete the collection of the tailings and facilitate unified processing of the tailings. The material blocking cover 310 prevents the tailings from scattering during the blowing process, which can protect the production environment and is beneficial to the health of the workers.
[0032] Further, see Figure 3 According to some embodiments of the present invention, a filter plate 322 is provided at the opening of the receiving trough 321, and the filter plate 322 is evenly provided with a plurality of filter ports, so as to prevent the finished film from being blown into the receiving trough 321 when the wind force is too strong.
[0033] Further, see Figure 3 According to some embodiments of the present invention, a water inlet port 323 connected to the material receiving trough 321 is provided on one side outer wall of the first collecting box 320, and a water outlet port 324 connected to the material receiving trough 321 is provided at the bottom of the first collecting box 320. The water outlet port 324 is provided with a drain valve. Water is injected into the material receiving trough 321 through the water inlet port 323. The tailings enter the material receiving trough 321 and come into contact with the water. The tailings are adsorbed by the water to the inside of the material receiving trough 321, which is convenient for collecting the tailings. The water and tailings in the material receiving trough 321 can be conveniently discharged through the drain valve, which is convenient for the staff to collect and process the tailings.

When the pellets come into contact with the bevel of the thread, the rotating bevel surface generates a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel of the extruder 110, and the collision and friction between the particles, and also due to the external heating of the barrel, the molten plastic is gradually melted. The impurities are removed by the head filter 130 and come out from the die mouth of the die head 140. After being cooled by the cooling ring 150, the film is blown into a film by the herringbone plate 160. The film is collected by the collecting roller 170 and then pulled to the cutting device 200 by the pulling roller 180.
[0038] Further, see Figure 5 According to some embodiments of the utility model, a sieve plate 123 is provided in the feed box 120, and the sieve plate 123 is provided with mesh holes.

[0039] Specifically, the plastic to be processed is put into the lower hopper 121, and then the plastic falls onto the screen plate 123, and is screened through the provided meshes to let particles of appropriate size fall, and then the unqualified plastic falls into the second collection box 124 for recycling.
[0040] Further, see Figure 1According to some embodiments of the utility model, the film blowing device 100 also includes a second blower 151 and a refrigerator 152. The air outlet of the second blower 151 is connected to the refrigerator 152. The air outlet of the refrigerator 152 is connected to the cooling ring 150 through a pipeline. The wind speed can be increased by the second blower 151, and then the refrigerator 152 is connected to the cooling ring 150, so that the cooling ring 150 can quickly discharge cold air to cool down and accelerate the cooling rate.
[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
