Technical Field
[0001] The utility model belongs to the technical field of film pasting correction, and more specifically, particularly relates to a position correction component for a film pasting machine. Background Technique
[0002] The reasons for the deviation of the position during film feeding may include the quality of the packaging material, the installation position of the guide wheel, the wear and cleaning of the roller, the levelness of the film rack, and the failure of the control system. The deviation of the film feeding will cause an offset in the packaging finished product, which needs to be adjusted and corrected through the fine-tuning device on the film rack. This not only increases the operation complexity but also may require random adjustment during the operation of the packaging machine due to the uneven edges of the film roll. For the existing film pasting machines, when installing the rolled film, it is necessary to manually adjust it to be centered, which is time-consuming. Therefore, a position correction component for a film pasting machine is proposed. Content of the Utility Model

After placing the rolled film on the film feeding shaft, by rotating the first nut with an external wrench to drive the worm to rotate, the worm drives the rotating shaft and the driving block to rotate through the worm gear. Since one end of the driving block is larger than the other end in size, the slider inside the chute is pushed to move outwards. The slider comes to the outside through the movable groove on the film feeding shaft, and the inclined surface on the slider pushes the film feeding shaft to be centered to solve the problem that for the existing film pasting machines, when installing the rolled film, it is necessary to manually adjust it to be centered, which is time-consuming as proposed in the above background technique.

A plurality of movable grooves 2 are formed on the outer side of the film feeding roller 1. The outer side of the film feeding roller 1 is also provided with a first installation groove 3 and a second installation groove 4. The inner side of the film feeding roller 1 is rotatably connected with a rotating shaft 5. A plurality of driving blocks 6 are fixed on the outer side of the rotating shaft 5. The inner side of the film feeding roller 1 is also rotatably connected with a worm 7. One end of the worm 7 is fixed with a first nut 8. The outer side of the worm 7 is meshed with a worm gear 9. The inner side of the worm gear 9 is coaxially fixed with the outer side of the rotating shaft 5. The inner side of the film feeding roller 1 is also rotatably connected with a bidirectional lead screw 10. One end of the bidirectional lead screw 10 is fixed with a second nut 11. Two movable rings 12 are threadedly connected to the outer side of the bidirectional lead screw 10. A guide rod 14 is slidably connected inside the movable ring 12. Both ends of the guide rod 14 are fixed to the inner side of the film feeding roller 1. The guide rod 14 is parallel to the bidirectional lead screw 10. A plurality of sliding grooves 15 are formed on the outer side of the movable ring 12. A slider 16 is slidably connected inside the sliding groove 15. A sliding surface 17 is formed on the side of the slider 16 close to the rotating shaft 5. The outer shape of the sliding surface 17 matches the outer shape of the outer side of the driving block 6. The inner side of the sliding surface 17 is in sliding contact with the outer side of the driving block 6. An inclined surface 13 is formed on the side of the slider 16 away from the rotating shaft 5. The slider 16 is made of a magnetic material, and the driving block 6 is made of a ferromagnetic material. The center of the rotating shaft 5 coincides with the center of the film feeding roller 1.

The worm 7 drives the rotating shaft 5 and the driving block 6 to rotate through the worm gear 9. Since one end of the driving block 6 has a larger size than the other end, the slider 16 inside the sliding groove 15 is pushed to move outwards. The slider 16 comes to the outside through the movable groove 2 on the film feeding roller 1. The inclined surface 13 on the slider 16 pushes the film feeding roller 1 to be centered. Through the above process, the problem that in the existing film laminating machine, when installing the roll film, it is necessary to manually adjust it to be centered, which is time-consuming, is solved. The second nut 11 is rotated by an external wrench to drive the bidirectional lead screw 10 to rotate.

[0025] Specific usage method and function of this embodiment: After placing the winding film on the feeding reel 1, the first nut 8 is rotated by an external wrench to drive the worm 7 to rotate. The worm 7 drives the rotating shaft 5 and the driving block 6 to rotate through the worm gear 9. Since one end of the driving block 6 is larger than the other end, the slider 16 inside the chute 15 is pushed to move outwards. The slider 16 comes to the outside through the movable groove 2 on the feeding reel 1, and the inclined surface 13 on the slider 16 pushes the feeding reel 1 to be centered;
