[0002] In today's advertising field, advertising scrolling devices have become an extremely common advertising tool due to their ability to display multiple advertisements in a loop. Most of these devices on the market consist of a scroll system, a drive motor, a control system, and an outer frame structure. The scroll system is responsible for carrying the scrolling and unrolling of the advertisement images, the drive motor provides power output, and the control system uses a preset program to achieve timed switching of multiple images.

[0003] However, during long-term use, the connection between the scroll and the advertising image is prone to wear due to frequent opening and closing. During the high-frequency start-stop process, the uneven force often causes jamming, thus shortening the overall service life of the equipment. Furthermore, when the image material is thick or the ambient humidity is high, the connecting fasteners are prone to loosening, causing the image to shift or even wrinkle, affecting the display effect. Utility Model Content

[0004] The purpose of this utility model is to provide an advertising scrolling playback device to solve the problems mentioned in the background art, such as the wear and tear of the connection between the scroll and the advertising image due to frequent opening and closing, the frequent jamming due to uneven force during the high-frequency start and stop of the device, which shortens the overall service life of the device, and the loosening of the connecting fasteners when the image material is thick or the ambient humidity is high, which can cause the image to shift or even wrinkle, affecting the display effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an advertising scrolling playback device, including an outer frame, which is the shell of the advertising playback device, and a display panel is covered at the opening of the outer frame. The display panel is used to display advertising images and is made of transparent or semi-transparent material, which protects the internal advertising images while allowing the audience to view them. The outer frame of the equipment is a hollow frame structure, and the display panel is sealed to the outer frame of the equipment. One drive roller is installed at the upper and lower ends of the inner side of the outer frame of the equipment, and a limiting roller is installed between the two drive rollers. The two ends of the drive roller are rotatably connected to the outer frame of the equipment through bearings, and one end of the drive roller is connected to a drive motor. The drive motors of the two drive rollers rotate in the same direction. The limiting roller and the driving roller are wrapped with display canvas, and the surface of the limiting roller is uniformly arrayed with rubber friction protrusions that contact the display canvas. The middle part of the display canvas unfolds through the inner area of ​​the display panel. A limiting ball frame is installed on the side of the limiting frame near the display canvas, and the balls in the limiting ball frame roll in contact with the side of the display canvas.

[0006] By adopting the above technical solution, the outer frame of the equipment is sealed to the display panel, which can protect the internal components from dust and moisture.

[0007] Preferably, a controller is installed inside the outer frame of the device, and an electric drive slide rail and a limiting rod are provided on the inner wall of the outer frame of the device.

[0008] By adopting the above technical solution, the controller is set up to realize the automated control of the equipment, and the electric drive slide rail one and limit rod two provide the structural basis for canvas tension adjustment, enhancing the controllability of equipment operation.

[0009] Preferably, the controller includes a microprocessor, a wireless communication module, and a motor drive module, and the microprocessor is connected to the drive components of the drive motor, the first electric drive slide rail, and the second electric drive slide rail respectively through the motor drive module.

[0010] By adopting the above technical solution, the modular composition of the controller enables it to precisely control the drive motor and electric drive slide rail, realize the adjustment of screen switching speed and dynamic adjustment of limit components, and improve the operating accuracy of the equipment.

[0011] Preferably, the display canvas has two upper and lower limiting frames at one end near the display panel, and a limiting ball frame is installed between the two limiting frames, and the two limiting ball frames and the two limiting frames together form a rectangular frame.

[0012] Using the above technical solution, the rectangular frame structure and the ball bearing restraint form a stable constraint from the side of the canvas, further preventing image shift and ensuring smooth scrolling.

[0013] Preferably, the ball bearing retainer includes a frame and balls, the frame has a U-shaped structure, and the balls are evenly installed inside the opening of the frame via a rotating shaft.

[0014] By adopting the above technical solution, the combination of the U-shaped frame and the ball bearings reduces friction on the sides of the canvas, reduces wear, and at the same time ensures effective positioning of the canvas.

[0015] Preferably, the surface of the display canvas is in rolling contact with the first limiting rod and the second electric drive slide rail, and the first limiting rod and the second electric drive slide rail are respectively located on the inner and outer sides of the display canvas.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This advertising scrolling playback device: 1. The ball bearing retainer adopts a U-shaped frame design. The internal ball bearings roll and contact the side of the display canvas through a pivot. The rolling contact reduces the coefficient of friction when the canvas is unfolded and retracted, reducing wear on the connection parts and maintaining contact stability when the canvas material is thick. At the same time, the rectangular frame formed by the two retainers and the two ball bearing retainers forms a closed-loop constraint from both sides of the canvas. Combined with the elastic tension of limit rod one and limit rod two, it effectively avoids the image shift or wrinkles caused by loose connection fasteners when the ambient humidity is high, thus improving the stability of the display effect. 2. The limiting rollers are rotatably connected to the outer frame of the equipment through bearings to ensure the coaxiality of power transmission. The drive rollers at both ends form auxiliary support, making the canvas more evenly stressed. In addition, the controller precisely controls the speed of the drive motor through the motor drive module, and works with the electric drive slide rail one and electric drive slide rail two to drive the limiting rod one and limiting rod two to adjust their positions in real time. It can dynamically compensate for the force deviation according to the change of canvas tension. Attached Figure Description

[0023] Please see Figures 1-6 This utility model provides a technical solution: an advertising scrolling playback device, including an outer frame 1, a controller 2, a display panel 3, a limiting frame 4, a limiting ball frame 5, a display canvas 6, a limiting roller 7, a driving roller 8, a first limiting rod 9, a first electric drive slide rail 10, a second electric drive slide rail 11, and a second limiting rod 12. Among them, the outer frame 1 is the shell of the advertising playback device. The opening of the outer frame 1 is covered with a display panel 3, which is used to display the advertising image. It is made of transparent or semi-transparent material, which protects the internal advertising image while allowing the audience to view it. The outer frame 1 of the equipment is equipped with a controller 2, and the inner wall of the outer frame 1 is provided with an electric drive slide rail 10 and a limit rod 2 12. The controller 2 includes a microprocessor, a wireless communication module and a motor drive module. The microprocessor is connected to the drive components of the drive motor, the electric drive slide rail 10 and the electric drive slide rail 2 11 through the motor drive module. The outer frame 1 of the equipment is a hollow frame structure, and the display panel 3 is sealed to the outer frame 1 of the equipment. One drive roller 8 is installed at the upper and lower ends of the inner frame 1 of the equipment. The limit roller 7 is installed between the two drive rollers 8. The two ends of the drive roller 8 are rotatably connected to the outer frame 1 of the equipment through bearings, and one end of the drive roller 8 is connected to a drive motor. The drive motors of the two drive rollers 8 rotate in the same direction. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the outer frame 1 of the equipment is fixed in the preset installation position to ensure that the frame is stable. The display panel 3 is installed at the opening of the outer frame 1 to seal it with the outer frame and form a closed display space. Drive rollers 8 are installed at the upper and lower ends inside the outer frame 1 to ensure that both ends are firmly fixed. The limiting roller 7 is installed between the two drive rollers 8, and both ends are connected to the outer frame 1 of the equipment through bearings. A drive motor is installed at one end of the drive roller 8. The display canvas 6 is wrapped around the surface of the limiting roller 7 and the two drive rollers 8, so that the middle part of the canvas is unfolded in the inner area of ​​the display panel 3. The limiting frame 4 is installed at the upper and lower positions of the display canvas 6 near the display panel 3, and the limiting ball frame 5 is installed between the two limiting frames 4 to form a rectangular frame, ensuring that the balls of the limiting ball frame 5 are in contact with the side of the canvas. Electric drive slide rail 10 and electric drive slide rail 21 are installed on the inner wall of the outer frame 1 of the equipment. The two ends of the limiting rod 19 are slidably connected to the electric drive slide rail 10, and the two ends of the limiting rod 212 are slidably connected to the electric drive slide rail 21, so that the limiting rod 19 and the electric drive slide rail 211 are in contact with the inner and outer sides of the display canvas 6 respectively. The controller 2 is installed inside the outer frame 1 of the equipment, and the controller 2 is connected to the drive motor, electric drive slide rail 10 and electric drive slide rail 2 11 through the circuit to complete the circuit deployment.

[0024] The surface of the limiting roller 7 and the driving roller 8 is wrapped with the display canvas 6, and the surface of the limiting roller 7 is uniformly arrayed with rubber friction protrusions that contact the display canvas 6. The middle part of the display canvas 6 unfolds through the inner area of ​​the display panel 3. The limiting frame 4 is equipped with a limiting ball frame 5 on the side near the display canvas 6, and the balls in the limiting ball frame 5 roll in contact with the side of the display canvas 6. There are two limiting frames 4 at the end of the display canvas 6 near the display panel 3, and the limiting ball frame 5 is installed between the two limiting frames 4. The two limiting ball frames 5 and the two limiting frames 4 together form a rectangular frame. The surface of the display canvas 6 rolls in contact with the limiting rod 1 9 and the electric drive slide rail 2 11 respectively. The limiting rod 1 9 and the electric drive slide rail 2 11 are located on the inner and outer sides of the display canvas 6 respectively. The two ends of the limiting rod 1 9 are slidably connected to one electric drive slide rail 1 10 respectively, and the two ends of the limiting rod 2 12 are slidably connected to one electric drive slide rail 2 11 respectively. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, after the device is started, the microprocessor of the controller 2 sends an instruction to control the drive motor to run through the motor drive module. The drive motor drives the drive roller 8 to rotate around the bearing, pulling the display canvas 6 to move synchronously. When the drive roller 8 rotates in the forward direction, the canvas is conveyed from the lower drive roller 8 to the limit roller 7. The limit roller 7 conveys the canvas to the upper drive roller 8. The lower drive roller 8 and the upper drive roller 8 rotate synchronously. The reverse rotation is the opposite, realizing the switching of the image in the inner area of ​​the display panel 3 and completing the cyclic scrolling of multiple advertisements. During the scrolling of the canvas, the rectangular frame consisting of the limiting frame 4 and the limiting ball frame 5 constrains the side of the canvas. The balls of the limiting ball frame 5 rotate with the scrolling of the canvas to prevent side deviation and reduce friction. At the same time, the controller 2 controls the movement of the limiting rod 9 along the electric drive slide rail 10, which, together with the limiting rod 12 on the electric drive slide rail 11, forms an elastic tension force on the canvas from both sides to prevent wrinkles or loosening. Operators can send remote commands to the wireless communication module of controller 2 via external devices to adjust the speed of the drive motor to change the screen switching speed, and adjust the position of the limit rod by controlling the electric drive slide rail 10 and electric drive slide rail 21 to adapt to display canvas 6 of different sizes.

[0025] Working principle: When using this advertising scrolling playback device, the microprocessor of the controller 2 sends a command to start the drive motor via the motor drive module. The drive motor drives the drive roller 8 to rotate around the bearing. Because the display canvas 6 is wrapped around the surface of the limiting roller 7 and the upper and lower drive rollers 8, the rubber friction protrusions evenly arrayed on the surface of the limiting roller 7 further increase the gripping force of the limiting roller 7 on the surface of the display canvas 6. Then, the limiting rod 9 slides inward along the electric drive slide rail 10, which further increases the wrapping area of ​​the display canvas 6 and the limiting roller 7. This causes the drive roller 8 to pull the canvas when it rotates. When rotating in the forward direction, the canvas is conveyed from the lower drive roller 8 to the limiting roller 7, and the limiting roller 7 conveys the canvas to the upper drive roller 8. The lower drive roller 8 and the upper drive roller 8 rotate synchronously. When rotating in the reverse direction, the opposite is true. This realizes the switching of the image in the middle of the canvas in the inner area of ​​the display panel 3, and completes the cyclic scrolling of multiple advertisements. During the scrolling of the canvas, the rectangular frame formed by the limiting frame 4 and the limiting ball frame 5 constrains the sides of the canvas. The U-shaped frame opening of the limiting ball frame 5 faces the canvas, and the internal balls rotate with the scrolling of the canvas, which not only prevents side deviation but also reduces friction to ensure stability. At the same time, the inner and outer sides of the canvas 6 are in rolling contact with the limiting rod 9 and the electric drive slide rail 11 respectively. The limiting rod 9 is slidably connected to the electric drive slide rail 10 at both ends and moves along the slide rail under the control of the controller 2. Together with the limiting rod 12 on the electric drive slide rail 11, it forms an elastic tension force from both sides to prevent the canvas from wrinkling and loosening. The wireless communication module of controller 2 receives remote commands and can adjust the speed of the drive motor to change the switching speed. By controlling the electric drive slide rail 10 and electric drive slide rail 21, the position of the limit rod can be adjusted to adapt to different sized canvases. The sealed connection between the outer frame 1 and the display panel 3 protects the internal components, ensuring continuous and clear display of advertisements and increasing the overall practicality.
