By setting a straight air knife, an annular air knife 6 and a flat mouth air tube or a pointed air tube capable of bending the tube body, the principle of the division cleaning is used, and the surface dirt and saponification liquid are removed from the preliminary cleaning, the ring cleaning, and the dead angle cleaning; By using high-quality high-density PE sound-insulating cotton (wave type), the noise amplitude is effectively absorbed, the resonance is reduced, and the jitter is reduced; the anti-vibration unit of the left and right dislocations in the sliding base 41 is used to chuck the product opening and rotate it on the rotating clip 45. The product is completely fixed, so that it can be effectively and stably conveyed to the gluing process, ensuring the clean and tidy sizing and the progress of the gluing position, and improving the yield rate.

The specific work arrangement is as follows:

1 The product enters from the inlet of the noise reduction box 1 and rotates through the through hole in the support base. By rotating the support base, the angle of the straight air knife is adjusted by 180°, and the product is blown at an angle of 45° with the product, and the upper and lower saponification liquid is initially filtered. And dirty, the air outlet direction of the straight air knife is shown in the arrow of Figure 3;

2 The product passes through the annular air knife 6, and the rotary airflow blows to filter out 90% of the surface of the product, and the air outlet direction of the annular air knife 6 is as shown by the arrow in FIG. 4;

3 The product passes through the tracheal shunt 7 and separates 8 nozzle-shaped trachea or / or flat-mouth trachea to clean the dead corner of the product, and finally achieves the function of completely clearing the tear. The pressure of the pointed or flat mouth trachea is relatively reduced, and the noise is small;

4 After the product passes through the first space, the second space and the third space in turn, the step blowing can reduce the jitter of the product, clean up the overall effect, and the blowing sound of the straight air knife is muffled, which is better than the sharp sound of the trachea. More; finally, the product passes through the anti-shake device 4 to substantially remove the blown jitter.

5 There is a blue film on the surface of the product. When the air is blown, the air pressure causes jitter. When the blue film is torn, the camera will also generate a large amount of jitter, which makes the position of the glue to be greatly deviated. By adjusting the rotating clip 45 on the seat 42, it is stuck. The opening of the product adjusts the height of the adjusting seat 42 in a vertical direction by twisting the second adjusting screw 490 so as to be on a horizontal line, so that the anti-shake device 4 can secure all the retort products, absorb the blowing and tearing molds. The jitter, and finally ensure that the product delivered to the gluing process is not shaken.

6 The above combination of the high-density PE sound-insulating cotton in the side wall of the noise-reducing box 1 effectively absorbs the vibration of the air-injection and the vibration of the box caused by the noise resonance.
