[0002] The existing plastic film is transported to the receiving roller for winding through fixed guide rollers. However, in the actual transportation process, the mechanical vibration, guide roller deviation, bearing wear, tension fluctuation caused by the viscosity difference of the moving diaphragm and the imbalance of the operating speed of each production unit in the equipment objectively exist in the equipment processing and production process. The plastic film cannot be kept neat at all times and will deviate to a certain extent. This will cause uneven edges when winding the plastic film, thereby affecting the appearance of the wound plastic film. Therefore, a correction device is needed.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 7As shown, a deviation correction device for film winding includes a frame 1, a deviation correction roller 3 is installed on the frame 1 through a drive structure 2, the drive structure 2 includes a slide rail 201, two slide rails 201 are installed on the frame 1, a mounting block 4 is fixedly connected to the side wall of one of the slide rails 201, an adjustment structure 5 is installed on the mounting block 4, the adjustment structure 5 includes a sliding sleeve 501, the sliding sleeve 501 is installed on the mounting block 4, and a sliding rod is slidably connected in the sliding sleeve 501 502, a mounting structure 6 is installed at the end of the sliding rod 502, and the mounting structure 6 includes a mounting seat 601. The end of the sliding rod 502 is fixedly connected to the mounting seat 601, and a fixing rod 602 is engaged with the mounting seat 601. A slot 604 is provided on the fixing rod 602, and a block 603 is slidably connected to the mounting seat 601. The end of the block 603 is engaged with the slot 604, and the end of the fixing rod 602 is fixedly connected to the correction sensor 7.

[0026] As a technical optimization solution of the present invention, the fixing rod 602 is an "L"-shaped structure as a whole, and the end of the fixing rod 602 is a trapezoidal structure; the fixing rod 602 drives the correction sensor 7 to quickly achieve initial fixation, preventing the fixing rod 602 from slipping off the mounting seat 601.

[0027] As a technical optimization solution of the present invention, a second guide rod 606 is fixedly connected to the mounting seat 601, and the clamping block 603 is slidably connected to the second guide rod 606. A tension spring 605 is provided on the outer sleeve of the second guide rod 606. The two ends of the tension spring 605 are respectively fixedly connected to the mounting seat 601 and the clamping block 603. The clamping block 603 is an "L"-shaped structure as a whole, and the end of the clamping block 603 is an inclined structure. When installing the deviation correction sensor 7, the end of the fixing rod 602 is aligned with the end of the mounting seat 601. The mounting slots are aligned, and then the fixing rod 602 is pressed into the mounting slot. Since the end of the block 603 is a sloped structure, it has a guiding effect on the block 603, so that the fixing rod 602 resists the block 603 and slides toward the outside of the mounting seat 601. The block 603 drives the tension spring 605 to extend. When the slot 604 on the fixing rod 602 is aligned with the block 603, the tension spring 605 resets and drives the block 603 to engage in the slot 604, thereby further limiting the fixing rod 602, and making the installation of the correction sensor 7 more stable and firm.

[0028] As a technical optimization solution of the present invention, the end of the sliding sleeve 501 is fixedly connected to a connecting sleeve 504, and a limiting rod 505 is slidably connected inside the connecting sleeve 504. A plurality of limiting holes 503 are equidistantly provided on the sliding rod 502, and the limiting rod 505 is engaged with one of the limiting holes 503. An anti-slip ring 506 is fixedly connected to the limiting rod 505, and a spring 507 is fixedly connected between the anti-slip ring 506 and the connecting sleeve 504. When the position of the deviation correction sensor 7 needs to be adjusted according to the width of the film to be reeled in, the limiting rod 505 is pulled outward to release the spring. The positioning rod 505 and the limiting rod 505 drive the anti-slip ring 506 to slide outward, and the anti-slip ring 506 resists the spring 507 and contracts, so that the limiting rod 505 no longer engages with the limiting hole 503, and then the sliding rod 502 is pulled toward the outside of the sliding sleeve 501, and the sliding rod 502 drives the correction sensor 7 to move toward the film through the mounting structure 6. When the correction sensor 7 is adjusted to a suitable position, the limiting rod 505 is released, and the spring 507 resets and drives the limiting rod 505 to engage with the limiting hole 503, thereby quickly limiting the sliding rod 502, and thus keeping the correction sensor 7 stable.

[0029] As a technical optimization solution of the present invention, a slider 202 is slidably connected to the slide rail 201, a rotating shaft 206 is fixedly connected to the slider 202, a connecting block 207 is rotatably connected to the rotating shaft 206, a bearing seat 208 is fixedly connected to the connecting block 207, and the correcting roller 3 is rotatably connected between the two bearing seats 208, one of the slide rails 201 is rotatably connected to a screw rod 203, the screw rod 203 is threadedly connected to the slider 202, a motor 209 is installed on the frame 1, the output shaft of the motor 209 and the end of the screw rod 203 are fixedly connected to a pulley 210, and a belt 205 is wound between the two pulleys 210; during the operation of the film winding structure, when the correcting sensor 7 senses the edge position of the film on the surface of the correcting roller 3 When a change occurs, the correction sensor 7 will transmit a signal to the controller unit, which will drive the motor 209 to rotate. The output shaft of the motor 209 will drive one of the pulleys 210 to rotate. The pulley 210 will drive another pulley 210 to rotate through the belt 205. The other pulley 210 will drive the screw rod 203 to rotate on the slide rail 201. The screw rod 203 thread drives the slider 202 to slide on the slide rail 201. The slider 202 drives the correction roller 3 to move. The correction roller 3 drives another slider 202 to slide on the other slide rail 201. At the same time, the correction roller 3 will rotate on the rotating shaft 206 through the bearing seat 208 and the connecting block 207, so that the correction roller 3 rotates around its own axis by a certain angle, thereby changing the force direction of the film on the correction roller 3, so that the film returns to the correct running path.

[0030] As a technical optimization solution of the present invention, a first guide rod 204 is fixedly connected to the slide rail 201, and the slider 202 is slidably connected to the first guide rod 204; the setting of the first guide rod 204 has a guiding effect on the slider 202, making the sliding of the slider 202 more stable.

[0031] When the present invention is in use, first, when installing the deviation correction sensor 7, align the end of the fixing rod 602 with the installation slot on the mounting seat 601, and then press the fixing rod 602 into the installation slot. Since the end of the clamping block 603 is in an inclined structure, it has a guiding effect on the clamping block 603, so that the fixing rod 602 contacts the clamping block 603 and slides toward the outside of the mounting seat 601. The clamping block 603 drives the tension spring 605 to extend. When the clamping slot 604 on the fixing rod 602 is aligned with the clamping block 603, the tension spring 605 is reset and drives the clamping block 603 to engage in the clamping slot 604, thereby further fixing the fixing rod 602. When the film is to be wound up, the limit rod 505 is pulled outward, and the limit rod 505 drives the anti-slip ring 506 to slide outward, and the anti-slip ring 506 resists the spring 507 and contracts, so that the limit rod 505 is no longer engaged with the limit hole 503, and then the sliding rod 502 is pulled toward the outside of the sliding sleeve 501, and the sliding rod 502 drives the correcting sensor 7 to move toward the film through the mounting structure 6. When the correcting sensor 7 is adjusted to a suitable position, the limit rod 505 is released, and the spring 50 7 resets and drives the limit rod 505 to engage with the limit hole 503, thereby quickly limiting the slide bar 502, thereby keeping the correction sensor 7 stable; during the operation of the film winding structure, when the correction sensor 7 senses that the edge position of the film on the surface of the correction roller 3 has changed, the correction sensor 7 will transmit a signal to the controller unit, which drives the motor 209 to rotate. The output shaft of the motor 209 drives one of the pulleys 210 to rotate, and the pulley 210 drives the other pulley 210 to rotate through the belt 205, and the other pulley 210 drives the screw rod 20 3 rotates on the slide rail 201, the lead screw 203 threadedly drives the slider 202 to slide on the slide rail 201, the slider 202 drives the correcting roller 3 to move, and the correcting roller 3 drives another slider 202 to slide on the other slide rail 201. At the same time, the correcting roller 3 rotates on the rotating shaft 206 through the bearing seat 208 and the connecting block 207, so that the correcting roller 3 rotates around its own axis by a certain angle, thereby changing the force direction of the film on the correcting roller 3 and returning the film to the correct running path; the setting of the first guide rod 204 has a guiding effect on the slider 202, making the sliding of the slider 202 more stable.
