[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: an automatic deviation correction device for packaging film processing, comprising: a support bracket 1 and a deviation correction component 7, a first vertical frame 2 is fixed on both sides of one end of the top of the support bracket 1, a film winding drum can be placed on the first vertical frame 2, and a component that is conducive to the rotation of the winding drum can also be assembled on the first vertical frame 2. Subsequently, the packaging film winding rod is placed on the first vertical frame 2 and the winding rod is driven to rotate by the rotating component, so that the packaging film can be rolled up; a mouth frame 3 is fixed on the top of the support bracket 1; the deviation correction component 7 is arranged at the top of the mouth frame 3, and the deviation correction component 7 includes a bidirectional screw 72 rotating on the top of the mouth frame 3, a strip guide hole 71 opened on the top of the mouth frame 3, a servo motor 73 installed on one side of the mouth frame 3 to drive the bidirectional screw 72 to rotate, and an F-type deviation correction bracket 74 passing through the strip guide hole 71, and the F-type deviation correction bracket 74 and the bidirectional screw 72 are threadedly connected. The correction component 7 also includes a short roller body 75 rotating in the F-type correction bracket 74, and the diameter of the short roller body 75 is larger than the side view width of the F-type correction bracket 74. The film is in contact with the short roller body 75 at both sides and near the edge. The friction between the packaging film and the F-type correction bracket 74 is reduced by the cooperation of the short roller body 75, thereby reducing the damage to the packaging film caused by the edge of the F-type correction bracket 74; the servo motor 73 is started, and the output shaft of the servo motor 73 drives the bidirectional screw 72 to rotate while rotating forward and reversely. During the rotation of the bidirectional screw 72 and through the cooperation of the strip guide hole 71, the F-type correction bracket 74 is moved smoothly. At this time, the distance between adjacent F-type correction brackets 74 is adjusted, and the two sides of the film are between the F-type correction brackets 74. The function of the F-type correction bracket 74 can avoid the film from being skewed. If it is not used in the later stage, the edges of the two sides of the winding drum will be uneven after winding, which will affect the aesthetics of the winding drum state.

[0023] See also Figure 1-3, an automatic deviation-correcting device for processing packaging film, further comprising: a leveling assembly 4, the leveling assembly 4 being arranged at the top of the mouth-shaped frame 3. The leveling assembly 4 comprises a first tensioning roller body 41 rotating in the mouth-shaped frame 3, a U-shaped frame bracket 42 arranged in the mouth-shaped frame 3 and close to the top, and an extrusion roller body 44 rotating in the U-shaped frame bracket 42. The extrusion roller body 44 and the first tensioning roller body 41 clamp the film, but in the structure of the movement of the packaging film, the extrusion roller body 44 and the first tensioning roller body 41 can be urged to rotate simultaneously, and the leveling assembly 4 also comprises a one-way threaded screw 43 threadedly connected to the top of the mouth-shaped frame 3 and on both sides, and the bottom end of the one-way threaded screw 43 is rotatably connected to the top of the U-shaped frame bracket 42. The one-way threaded screw 43 is held by hand and rotated. During the rotation of the one-way threaded screw 43, the U-shaped frame bracket 42 can be adjusted in height up and down. The height of the U-shaped frame bracket 42 can be adjusted according to the thickness of the packaging film, so that the squeezing roller body 44 and the first tensioning roller body 41 clamp the packaging film. However, during the movement of the packaging film, the squeezing roller body 44 and the first tensioning roller body 41 are driven to rotate, so that the squeezing roller body 44 and the first tensioning roller body 41 can be used to simply level the packaging film.

[0024] See also Figure 1-4 , a second vertical frame 5 is provided at one end of the top of the support bracket 1 away from the first vertical frame 2, and a second tensioning roller 6 is rotated on the second vertical frame 5. A U-shaped groove is provided at the middle position of the second vertical frame 5, and the second vertical frame 5 supports the second tensioning roller 6, and the tensioning treatment of the packaging film is achieved through the action of the second tensioning roller 6; a reserved hole 9 is provided on the F-type correction bracket 74, and a distance sensor 8 is installed on the F-type correction bracket 74. During the movement of the F-type correction bracket 74, the distance between the F-type correction brackets 74 is obtained through the cooperation of the relative distance sensor 8, so that the distance between the F-type correction brackets 74 can be ensured to be suitable for the distance of the processing film, wherein the device is externally connected to a display control panel, and the display control panel and the input and output ends of the servo motor 73 and the distance sensor 8 are electrically connected.

[0025] Working principle: first, the film is wound around the second tensioning roller 6, and the film is wound around the first tensioning roller 41, and then the one-way threaded screw 43 is rotated, and the U-shaped frame bracket 42 is moved up and down by rotating the one-way threaded screw 43. At this time, the extrusion roller 44 and the first tensioning roller 41 contact the film, and then the servo motor 73 is started, and the output shaft of the servo motor 73 drives the bidirectional screw 72 to rotate. At this time, with the cooperation of the strip guide hole 71, the F-type correction brackets 74 are close to each other, and are started by the distance sensor 8, so as to drive the distance between the F-type correction brackets 74. At this time, both sides of the film are in the F-type correction brackets 74. Through the cooperation of the F-type correction brackets 74 on both sides, the film is prevented from being skewed during the processing process, and at the same time, it is also prevented from being too close to each other, and both sides of the film are in a blocked state; and through the cooperation of the first tensioning roller 41 and the extrusion roller 44, the film can be tightly leveled to ensure the flatness of the film.
