A groove for placing the support shaft 41 of the roller 4 is provided at the top of the pillar 2. At the same time, a third motor 21 and a rotating assembly are provided on one side of the pillar 2, and the third motor 21 is connected to the rotating assembly through a transmission part 20, and the third motor 21 is connected to an external power supply for power supply. Among them, the rotating assembly includes two fixed blocks 18 provided on one side of the pillar 2, and a rotating shaft 19 is rotatably provided between the two fixed blocks 18, one end of the rotating shaft 19 passes through the fixed block 18 and extends outward, and a connecting block 17 is also provided on the rotating shaft 19, and a limit block 3 is provided on the connecting block 17, and a groove cooperating with the support shaft 41 is provided on the limit block 3, and the groove on the limit block 3 cooperates with the groove at the top of the pillar 2 to limit the support shaft 41 of the roller 4. The transmission part 20 for connecting the third motor 21 and the rotating assembly includes a worm 202 arranged at the output end of the third motor 21 and a worm wheel 201 arranged at the extending end of the rotating shaft 19, and the worm 202 and the worm wheel 201 are meshed.

[0022] Specifically, when it is necessary to limit the support shaft 41 of the roller 4 placed in the groove of the pillar 2, the third motor 21 can be started, the third motor 21 drives the worm 202 on its output end, the worm 202 drives the worm wheel 201 connected to the rotating shaft 19, the rotating shaft 19 rotates together with the worm wheel 201 and drives the limit block 3 to rotate around the rotating shaft 19 through the connecting block 17, so that the limit block 3 is separated from the pillar 2, and the limit block 3 is released from the support shaft 41 of the roller 4. Similarly, when it is necessary to limit the support shaft 41, the third motor 21 can be started and reversed, the third motor 21 drives the worm 202 to reverse, the worm wheel 201 meshed with the worm 202 also starts to rotate in the opposite direction, the rotating shaft 19 connected to the worm wheel 201 rotates, and drives the limit block 3 to rotate through the connecting plate, and implements the limit work of the support shaft 41. The transmission part 20 uses a worm wheel 201 and a worm 202, which have a self-locking function, and can reduce the force on the third motor 21 when the limit block 3 is driven to rotate, thereby increasing the service life of the third motor 21. The transmission part 20 can also be driven by a gear 102, and no further restrictions are made here.

[0023] like Figure 2 and Figure 3As shown, a frame 11 is provided on the base 1, a second motor 12 is provided at the top of the frame 11, and a second rubber wheel 13 is provided at the output end of the second motor 12. At the same time, a first rubber wheel 5 is provided at one end of the support shaft 41, and the second rubber wheel 13 cooperates with the first rubber wheel 5. After the support shaft 41 is limited by the limit block 3, the second motor 12 is started, and the second motor 12 drives the second rubber wheel 13 to rotate. The first rubber wheel 5 that cooperates with the second rubber wheel 13 will also start to rotate under the action of the second rubber wheel 13, and the roller 4 connected to the support shaft 41 will also start to rotate, completing the paper rolling work. As a further improvement, two slide plates 14 are also provided at the bottom end of the second motor 12, and the slide plates 14 and the top plate of the frame 11 are set to slide up and down, and a spring 16 is provided between the top surface of the frame 11 and the bottom surface of the second motor 12. In order to prevent the slide plate 14 from being separated from the top plate of the frame 11 under the action of the spring 16, the bottom ends of the two slide plates 14 are connected by a stop plate 15, and the stop plate 15 and the two slide plates 14 are detachably connected by bolts. After the support shaft 41 is stuck in the groove of the pillar 2, the first rubber wheel 5 on the support shaft 41 lowers the second motor 12 through the second rubber wheel 13, and the second motor 12 slides on the frame 11 through the slide plate 14 and presses down the spring 16, so that the friction between the first rubber wheel 5 and the second rubber wheel 13 can be increased under the action of the spring 16, which is conducive to the transmission between the first rubber wheel 5 and the second rubber wheel 13. In order to facilitate the positioning of the roller 4 relative to the pillar 2, a positioning piece 22 is provided on the support shaft 41, and the distance between the two positioning pieces 22 is adapted to the distance between the outer walls of the two pillars 2.
