[0040] Working principle:

[0041] When in use, first place the frame 1 on the ground. After the frame 1 is firmly placed, pass the film body 7 through the frame 1 along the correction mechanism 4, then start the stepper motor 2, and drive the belt group 6 to rotate through the stepper motor 2. The correction mechanism 4 is connected to the belt group 6, and the belt group 6 drives the correction mechanism 4 to operate, and then carry out the correction work. When the size of the discharge roller 43 and the feed roller 41 needs to be changed due to production needs, the fixing mechanism 5 to the flip plate 3 can be released. It should be noted that before releasing the fixing of the flip plate 3 Before the material is corrected, it is necessary to stop the stepper motor 2. After the stepper motor 2 stops rotating, the flip plate 3 can be released. After the fixing mechanism 5 releases the fixation of the flip plate 3, the flip plate 3 is flipped in the direction away from the correcting mechanism 4 to expose the discharge roller 43 and the feed roller 41 in the correcting mechanism 4. Only then can the discharge roller 43 and the feed roller 41 be replaced. After the replacement of the discharge roller 43 and the feed roller 41 is completed, the flip plate 3 is rotated in the opposite direction so that the flip plate 3 restricts the discharge roller 43 and the feed roller 41 again, and then the position of the flip plate 3 is re-locked by the fixing mechanism 5.

[0042] After the stepper motor 2 is started, the belt group 6 drives the rotating shaft 42 and the discharge roller 43 to rotate through the pulley, and the feed roller 41 on the rotating shaft 42 is used to guide the film body 7 into the correction mechanism 4. When the film body 7 passes through the discharge roller 43, the guide rings 46 on both sides of the discharge roller 43 are used to guide the deviated film body 7 to the discharge roller 43. At the same time, because the discharge roller 43 and the rotating shaft 44 are connected by the sliding ball 45, the discharge roller 43 can slide freely on the rotating shaft 44. When the film body 7 passes through the discharge roller 43, through the stretching between the discharge rollers 43, if the film body 7 does not deviate, the tension on both sides of the film body 7 is equal, and the discharge roller 43 will not slide in position. After the position of the film body 7 deviates, under the stretching between the discharge rollers 43, there is a tension difference between the tension on both sides of the film body 7, so the discharge roller 43 automatically slides in the direction of greater tension, thereby automatically correcting the position of the film body 7.

[0043] When it is necessary to change the discharge roller 43 and the feed roller 41, the stepper motor 2 must be stopped first. After the stepper motor 2 stops rotating, the plug block 55 is pulled upward to make the plug block 55 slide out of the groove on the frame 1. At the same time, as the plug block 55 slides, the top spring 54 is compressed, so that the top spring 54 accumulates elastic potential energy. After the plug block 55 slides out of the groove, the lock on the rotating rod 51 is released. Then the rotating rod 51 is rotated in the direction of the frame 1, and the plug block 55 is inserted into the frame 1 along the limiting groove 8 on the frame 1, thereby limiting the position of the rotating rod 51. It should be noted that two sets of fixing mechanisms 5 are provided on the frame 1. When it is necessary to detach the plug blocks 55 in the two sets of fixing mechanisms 5 from the flip plate 3 and then limit the fixing mechanisms 5 on the frame 1, it is only necessary to fix any one set of the fixing mechanisms 5 on the limiting groove 8, and the other set of the fixing mechanisms 5 can be rotated to the belt group 6.

[0044] After the plug block 55 releases the restriction on the flip plate 3, the flip plate 3 can be flipped in the direction away from the frame 1, so as to release the restriction on the discharge roller 43 and the feed roller 41, and then the replacement work can be carried out. After the discharge roller 43 and the feed roller 41 are replaced, it is only necessary to rotate the flip plate 3 in the opposite direction. After the flip plate 3 is reset, the position of the flip plate 3 is first maintained, and then the plug block 55 is pulled up to rotate the rotating rod 51 along the fixed axis 52 so that the plug block 55 is aligned with the groove on the flip plate 3. The limit rod 56 on the support frame 53 is used to limit the position of the plug block 55 to prevent the position of the plug block 55 from shifting. Then the pulling force on the plug block 55 is released, and the top spring 54 is able to release the elastic potential energy, thereby pushing the plug plate to be inserted into the groove, so as to re-limit the position of the flip plate 3.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
