At this time, the internal air pump inside the feeding support frame transmits gas to the connected connector and the bottom of the film blowing table through the connected T-tube interval.

The arc-shaped semi-arc connecting tube structure is used to facilitate the subsequent scraping and cleaning of the notch. At the same time, the air introduced into the connector is discharged from the top of the film blowing table through the connected outer drum tube. The discharged air corrects the position of the film blowing, prevents the blow mold from tilting to one side, and cooperates with the air blown out from the center of the film blowing table to cool the shaped blown film.

In addition, the arc-shaped semi-arc connecting tube 65 structure facilitates the subsequent scraping and cleaning of the notch. At the same time, the air introduced into the connector 510 is discharged from the top of the film blowing table 55 through the connected outer drum tube 511. The discharged air plays a role in correcting the film blowing position, preventing the blow mold from tilting to one side, and cooperates with the air blown out from the center of the film blowing table 55 to cool the shaped blown film.

When the transmitted air in the exhaust pipe 61 passes through the connected agitation groove 64, the air at the agitation groove 64 will blow the vortex blades 63 in the blast end shell 62 to rotate, so that the vortex blades 63 rotate and then pump the air inside the blast end shell 62 to flow and be discharged outward through the vortex blades 63. The air in the semi-arc connecting pipe 65 connected to the blast end shell 62 will flow with the air discharged from the inside of the blast end shell 62. When the air inside the semi-arc connecting pipe 65 is reduced, the air is extracted from the outside of the semi-arc connecting pipe 65 through the small holes on the surface of the semi-arc connecting pipe 65. The small holes on the general semi-arc connecting pipe 65 are used for extraction. The air drives the air flow around the blown film in the form of air, thereby preventing the blown film that has not been completely cooled from being deformed and wrinkled after being blown, thereby preventing the non-woven fabric from being coated and causing the film to be cooled. The effect of direct gas blowing on the blown film is reduced, and the film can be cooled. At the same time, the hydraulic rod 613 on the top plate 8 contracts downward to drive the vertical connecting rod 612 to push the connected pressure roller 611 downward, so that the pressure roller 611 moves along the bevel of the guide die side plate 67, so that the bevel of the guide die side plates 67 on both sides is compressed and squeezes the return spring along the transverse groove rod 69 through the connected slider 68 and approaches each other, so that the guide die side plate 67 drives the connected guide die roller 614 to squeeze the cooled blown film, so that the cooled blown film is squeezed flat for subsequent winding;

[0038] When the sliders 68 connected under the two guide mold side plates 67 approach each other, the sliders 68 move and drive the connected short sliding rods 71 ​​to move, and the V-shaped groove rods 72 slide through the short sliding rods 71 ​​to make the V-shaped groove rods 72 move downward as a whole, and the movement of the V-shaped groove rods 72 drives the connected thin connecting rods 73 and the pressure groove rods 74 to move downward together, and the connected pressure folding rods 75 are pressed downward through the pressure groove rods 74, so that the pressure folding rods 75 slide downward along the hinge plate 76, and when the pressure folding rods 75 move, they drive the connected upper locking hooks 78 to approach the lower locking hooks 77 connected to the hinge plate 76, so that the upper locking hooks 78 and the lower locking hooks 77 are The rotating shaft of the reel 79 is fixed, and the structure of the upper locking hook 78 and the lower locking hook 77 cooperates to facilitate the replacement and installation of the reel 79, thereby improving the work efficiency of replacing the reel 79. At the same time, when the left and right guide mold side plates 67 approach each other, the guide mold side plates 67 will drive the connected linkage rod 710, so that the linkage rod 710 pulls the hinge plate 76 toward the blow mold support frame 3, and the elastic sliding rod 713 connected to the support rod 712 pushes the connected pressure wheel arc plate 711 through the elastic spring to apply pressure to the blown film rolled on the reel 79, so as to avoid wrinkles in the blown film wrapped around the reel 79 and prevent the blown film rolled on the reel 79 from being too fluffy to improve the winding effect.
