[0002] Chinese patent document CN219771323U discloses a printing press take-up shaft moving device and a printing press. The take-up shaft moving device includes a bracket, a constant force pressing unit, and a synchronous pulley. The constant force pressing unit is mounted on the machine body, and its pressing end is connected to the bracket. A synchronous pulley is fixed to the lower side of the constant force pressing unit. The take-up shaft is mounted on the bracket, and a slide rail is mounted on the machine body. The bracket is slidably mounted on the slide rail. A mounting block is provided on one side of the bracket. A pressure roller is provided on one side of the synchronous pulley, and a fabric belt is mounted on both the synchronous pulley and the pressure roller. The mounting block is fixed to the fabric belt. The pressing direction of the constant force pressing unit is parallel to the moving direction of the take-up shaft. The synchronous pulley drives the synchronous belt to move, thereby moving the bracket on the slide rail and adjusting the relative position between the take-up shaft and the machine body. The constant force pressing unit provides stable pressure between the machine body and the bracket, maintaining a certain tension between the take-up shaft and the machine body, and maintaining a certain tension during winding.

[0003] The aforementioned printing press rewinding shaft moving device and printing press may not be able to position the material during rewinding when rewinding materials of different thicknesses, which may cause the material to become skewed and wrinkled, reducing the flatness of the rewinding.

A guide rail 13 is fixedly installed on one inner wall of the take-up housing 1. An installation housing 3 is provided inside the take-up housing 1. Two sets of positioning rollers 5 are provided inside the installation housing 3.

[0024] The auxiliary mechanism includes a positioning mechanism 4 and a detachable mechanism 6. The positioning mechanism 4 includes a threaded short bar 401, a connecting bar 402, a connecting frame 403, and a handle 404. The top of the mounting housing 3 is threadedly connected to the threaded short bar 401, and the connecting bar 402 is fixedly installed on the bottom inner side of the mounting housing 3. There are two sets of connecting frames 403. One end of the threaded short bar 401 extends into the interior of the mounting housing 3 and is rotatably mounted with one set of connecting frames 403. The top of the connecting bar 402 is fixedly mounted with another set of connecting frames 403, and the other end of the threaded short bar 401 is fixedly mounted with a handle 404. The positioning mechanism 4 can adjust the height of a set of positioning rollers 5, so that the two sets of positioning rollers 5 can position materials of different thicknesses. When winding them, it reduces the occurrence of material skewing and wrinkling, and improves the flatness of the material winding.

[0025] The detachable mechanism 6 includes a connecting block 601, a threaded short bar 602, and a handle 603. Two sets of connecting blocks 601 are fixedly installed on the top and bottom of the guide rail 13. Each of the four sets of connecting blocks 601 has a set of threaded holes. A set of threaded short bars 602 are threadedly connected to the other side of each of the four sets of connecting blocks 601. A set of handles 603 is fixedly installed at one end of each of the four sets of threaded short bars 602. The detachable mechanism 6 allows the guide rail 13 to be disassembled individually, which facilitates the replacement and maintenance of the guide rail 13, reduces maintenance costs, and improves the service life of the device.

[0026] Both sets of connecting frames 403 are rotatably mounted with a set of positioning rollers 5 inside.

[0027] Four sets of identical threaded holes are provided on one side of the winding housing 1, and the other end of the four sets of threaded short bars 602 extends to one side of the winding housing 1 through the threaded holes.

[0028] A motor 7 is fixedly installed on the rear side of the winding housing 1. The output shaft of the motor 7 extends into the interior of the winding housing 1 and is fixedly installed with a threaded rod 8. One end of the threaded rod 8 is rotatably installed on the inner front wall of the winding housing 1. A slider 9 is threadedly connected to the outer wall of the threaded rod 8. The slider 9 and the guide rail 13 are slidably installed. A fixing plate 10 is fixedly installed on the top of the slider 9. A motor 11 is fixedly installed on one side of the fixing plate 10. The output shaft of the motor 11 extends to the other side of the fixing plate 10 and is fixedly installed with a rotating rod 12. A strip-shaped opening is provided on the front side of the winding housing 1 for the guide rail 13 to pass through. A rectangular opening is provided on the rear side of the winding housing 1.

[0030] Working principle: When winding is required, one end of the material to be wound is passed through the rectangular opening and between the two sets of positioning rollers 5 and fixedly connected to the rotating rod 12. By rotating the threaded short rod 401 through the handle 404, the height of the connecting frame 403 is adjusted, thereby adjusting the distance between the two sets of positioning rollers 5, so that the two sets of positioning rollers 5 contact the material and position it. The start motor 11 is controlled, and the output shaft of the start motor 11 rotates to drive the rotating rod 12 to rotate and wind it. As the roll diameter gradually increases, the start motor 7 is controlled, which eventually drives the slider 9 to move laterally. By starting the cylinder 2, the height of the mounting housing 3 is adjusted. With the lateral movement of the slider 9, the tension during winding can be made uniform. When the guide rail 13 needs to be maintained or replaced, the four sets of threaded short rods 602 are rotated through the four sets of handles 603, so that the four sets of connecting blocks 601 are separated from the inner wall of one side of the winding housing 1. The guide rail 13 can be pulled out through the strip opening on the front side of the winding housing 1.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
