[0032] In a further embodiment, referring to Figure 1-Figure 4 The straight-moving rolling mechanism 2 includes a first frame 21 and a balancing roller 23. The lower end of the control rod 1 is rotatably connected to the first frame 21. The lower end of the front side of the first frame 21 is rotatably connected to the balancing roller 23. The balancing roller 23 is provided with two groups. The left and right ends of the first frame 21 are rotatably connected to the first roller 24. The first frame 21 is provided with a first driving component 25. The first driving component 25 includes a first motor 251 and a driving roller 255. The first frame 21 is rotatably connected to the driving roller 25 5. The driving roller 255 is located at the upper ends of the two groups of balancing rollers 23. The first motor 251 is fixedly connected inside the first frame 21. The first worm 252 is fixedly connected to the output shaft end of the first motor 251. The first rotating shaft 253 is rotatably connected inside the first frame 21. The first worm wheel 254 is fixedly connected to the side wall of the first rotating shaft 253. The first worm 252 and the first worm wheel 254 are meshed with each other. The right end of the first rotating shaft 253 is connected to the right end of the driving roller 255 through the first sprocket assembly 256.

[0033] In this embodiment, when the base paper roll only needs to move in a straight line, the first frame 21 can be moved to one side of the base paper roll by the control rod 1, so that the driving roller 255 is in contact with the side wall of the base paper roll, and then the first motor 251 is started to drive the first worm 252 to rotate, and then drive the first worm wheel 254 to rotate. The rotation of the first worm wheel 254 drives the first rotating shaft 253 to rotate. Since the right end of the first rotating shaft 253 is connected to the right end of the driving roller 255 through the first sprocket assembly 256, the driving roller 255 is driven to rotate. The rotation of the driving roller 255 will push the base paper roll to the specified position, thereby achieving the effect of saving the labor intensity of workers.

[0034] In a further embodiment, referring to Figure 5-Figure 6A reserved groove 26 is provided on the rear end surface of the first frame 21, and an arc groove 261 is provided on the side wall of the reserved groove 26.

The downward moving top rod 45 drives the extension rod to rotate with the rotating shaft 41, and drives the limit clamp 42 to move through the lever principle. At this time, the first bracket is moved backward again, so that the two-way electric telescopic rod 31 moves into the arc groove 261. At this time, the foot leaves the top rod 45, and the spring 44 restores the deformation, which drives the top rod 45 and the limit clamp 42 to reset. The reset limit clamp 42 fixes the two-way electric telescopic rod 31 in the reserved groove 26, thereby achieving the effect of fixing the turning assist mechanism 3.
