[0036] The limiting strip 7 passes through the third sprocket 613, the fourth sprocket 614, the first rotating wheel 641 and the second rotating wheel 642. A strip-shaped through groove is opened on the axis of the bottom surface of the limiting strip 7. The width of the strip-shaped through groove is greater than the thickness of the promotional paper. The strip-shaped through groove is located directly above the contact surface between the first rotating wheel 641 and the second rotating wheel 642. The bottom surface of the limiting strip 7 does not contact the first rotating wheel 641 and the second rotating wheel 642. The limiting strip 7 is fixedly connected to the rear railing frame 2 by vertical strips 71 at both ends. There are two groups of limiting strips 7 and vertical strips 71 and they are symmetrically distributed up and down.

[0037] The power device 4 includes a motor 41, a motor box 42 and a control panel 43. The motor box 42 is welded to the bottom surface of the rear fence frame 2. The motor 41 is installed in the motor box 42. The control panel 43 is provided on the outer side of the motor box 42. The control panel 43 is electrically connected to the motor 41. The bottom end of the transmission main shaft 51 passes through the rear fence frame 2 and is connected to the output end of the motor 41.

[0038] Specifically, the motor box 42 protects the motor 41 , and the motor box 42 can be opened to repair the motor 41 .

[0039] A glass 8 is installed in the middle of the front fence frame 1, and the distance from the glass 8 to the side plate of the rear fence frame 2 is greater than the distance from the limit strip 7 to the side plate of the rear fence frame 2.

[0040] A support column 21 is provided at the bottom of the rear fence frame 2 , and the rear fence frame 2 is fixed on the ground through the support column 21 .

[0041] Specifically, the motor 41 is turned on through the control panel 43, and the motor 41 drives the transmission main shaft 51 to rotate. The transmission main shaft 51 drives the transmission shaft 52 to rotate through the cooperation of the first sprocket 611 and the chain 62. The chain 62 drives the second sprocket 612 to rotate during the transmission process. The second sprocket 612 drives the third sprocket 613 and the first rotating wheel 641 to rotate through the long rotating drum 651. The third sprocket 613 correspondingly drives the fourth sprocket 614 and the second rotating wheel 642, so that the first rotating wheel 641 and the second rotating wheel 642 rotate in opposite directions.

[0042] Specifically, during the operation of the first rotating wheel 641 and the second rotating wheel 642, the movable plate 3 on one side is opened, and the side edge of the promotional paper is placed in the strip-shaped slot of the limiting strip 7. Under the guidance of the strip-shaped slot, the promotional paper is pushed in the direction of the first rotating wheel 641 and the second rotating wheel 642 until the side edge of the promotional paper contacts the first rotating wheel 641 and the second rotating wheel 642. Since the first rotating wheel 641 and the second rotating wheel 642 are in contact and rotate in opposite directions, the first rotating wheel 641 cooperates with the second rotating wheel 642 to clamp the promotional paper and push the promotional paper in the strip-shaped slot. Slide until the promotional paper completely enters the front column frame 1 and the rear column frame 2, the first rotating wheel 641 and the second rotating wheel 642 stop rotating, and the promotional paper is placed. Similarly, when replacing the promotional paper, the first rotating wheel 641 and the second rotating wheel 642 drive the promotional paper and push it out of the strip groove; the first rotating wheel 641 and the second rotating wheel 642 can not only move the promotional paper horizontally, but also clamp and fix the promotional paper after placement. The staff only needs to operate on the control panel 43 to automatically complete the placement of the promotional paper, which improves the convenience of replacing the promotional paper.

[0043] Working principle: The motor 41 is turned on through the control panel 43, and the motor 41 drives the transmission main shaft 51 to rotate. The transmission main shaft 51 drives the transmission cluster shaft 52 to rotate through the cooperation of the first sprocket 611 and the chain 62. The chain 62 drives the second sprocket 612 to rotate during the transmission process. The second sprocket 612 drives the third sprocket 613 and the first rotating wheel 641 to rotate through the long rotating drum 651. The third sprocket 613 correspondingly drives the fourth sprocket 614 and the second rotating wheel 642, so that the first rotating wheel 641 and the second rotating wheel 642 rotate in opposite directions. During the operation of the first rotating wheel 641 and the second rotating wheel 642, open the movable plate 3 on one side and put the side of the promotional paper into the limit position. In the strip groove of strip 7, under the guidance of the strip groove, the promotional paper is pushed into the direction of the first rotating wheel 641 and the second rotating wheel 642 until the side of the promotional paper contacts the first rotating wheel 641 and the second rotating wheel 642. Since the first rotating wheel 641 and the second rotating wheel 642 are in contact and rotate towards each other, the first rotating wheel 641 cooperates with the second rotating wheel 642 to clamp the promotional paper and push the promotional paper to slide in the strip groove until the promotional paper completely enters the front column frame 1 and the rear column frame 2. The first rotating wheel 641 and the second rotating wheel 642 stop rotating and the promotional paper is placed. Similarly, when replacing the promotional paper, the first rotating wheel 641 and the second rotating wheel 642 drive the promotional paper and push it out of the strip groove.
