The cylindrical film may be wrinkled when it is gradually pressed into a flat shape by the pressing roll 4. In order to reduce the possibility of the generation of the film wrinkles, referring to fig. 1, shallow grooves 41 may be formed in the squeeze roll 4, the shallow grooves 41 extend spirally from the middle of the squeeze roll 4 to both ends of the squeeze roll 4, the spiral directions of the shallow grooves 41 at both ends of the squeeze roll 4 are opposite, and when the film drives the squeeze roll 4 to rotate, the shallow grooves 41 enable the squeeze roll 4 to drive the film to spread from the middle of the squeeze roll 4 to both ends, so as to reduce the possibility of the generation of the film wrinkles.
The film blowing machine extrusion device is large and is installed indoors, and the indoor space is limited. When adjusting the contained angle of film direction of motion both sides support frame 3, in order to reduce the possibility that 3 butts of support frame cause the damage on the wall, refer to fig. 2, can be close to driven gear 5 fixedly connected with lug 7 in pivot 2, and connecting plate 1 is close to lug 7 fixedly connected with stopper 8. When driven gear 5 adjusts the contained angle of film direction of motion both sides support frame 3, lug 7 butt is on stopper 8, restriction driven gear 5 turned angle, reduces driven gear 5 and drives 3 butts of support frame and cause the possibility of damaging on the wall.
The cylindrical film may be displaced along the length of the squeeze roll 4 when passing through the squeeze device, thereby increasing the possibility of wrinkles occurring after the film is squeezed. In order to reduce the possibility of generating film wrinkles, referring to fig. 3, a cross bar 31 and a roller 9 may be disposed on the support frame 3, the cross bar 31 and the roller 9 are both horizontally disposed, the cross bar 31 is fixedly connected to the support frame 3, the cross bar 31 is disposed parallel to the squeeze roll 4, the roller 9 is detachably connected to the cross bar 31, the roller 9 is disposed on two sides of the film moving direction, and the roller 9 is perpendicular to the cross bar 31. After the included angle of the supporting frames 3 on the two sides of the film moving direction is adjusted to a proper position, the roller shaft 9 and the cross rod 31 are installed, the roller shaft 9 limits the film to deviate along the length direction of the squeezing roller 4, and the possibility of film wrinkle generation is further reduced.
The angle of film direction of motion both sides support frame 3 can be adjusted according to the film diameter, in order to make roller 9 can install on the support frame 3 of different states, refer to fig. 3, can be on horizontal sliding connection fixed block 91 on horizontal pole 31, the roller 9 both ends are pegged graft respectively and are passed fixed block 91, threaded connection has bolt 92 on the fixed block 91, bolt 92 can with the butt of roller 9.

Since the cylindrical film moves upward when it comes into contact with the roller shaft 9, the roller shaft 9 generates a large resistance to the cylindrical film. To prevent the resistance from damaging the film, referring to fig. 3, a roller 93 may be rotatably coupled to the peripheral wall of the roller shaft 9. When the film contacts with the roller, the film moves upwards to drive the roller 93 to rotate relative to the roller shaft 9, so that the resistance of the roller shaft to the cylindrical film is reduced, and the possibility that the film is damaged by the roller shaft is reduced.
When the cylindrical film is greatly deviated, the film comes into contact with the roller 93. In order to prevent the film from being scratched at the edges of the two ends of the roller 93, referring to fig. 3, the two ends of the roller 93 may be set to be smooth ends, so that the possibility of damaging the film can be reduced.
The film will be pushed against the roller 93, and at this time, the film will be deformed, and the film may be wrinkled when continuing to move upward, and in order to unfold the film passing through the roller 93, a rubber sleeve may be fixedly sleeved outside the roller 93. The rubber sleeve increases the friction force of the film for driving the roller 93 to rotate, the film can be vertically unfolded, and the possibility of wrinkles generated by the film is reduced.
Since the film will be deflected and abut against the roller 93, when the film deflection is large, the film will press the roller 93 inward greatly, and at this time, the film will continue to move upward and pass through the pressing device to be laminated, and the film may be wrinkled. In order to reduce the possibility of wrinkles occurring when the films are stacked, rollers 93 may be provided to be gradually thicker from the middle to both ends, referring to fig. 3. When the film deflection is large, the possibility of inward deformation of the film is reduced, and thus the possibility of wrinkles occurring when the film is flattened is reduced.
