[0032] like Figure 1As shown, in this embodiment, the advertising soft screen rolling device includes a rolling chamber 1, a transmission component 2, a drive component 3, a guide rail 4, a chain 5, a rope 6 and a curtain 7; wherein, the rolling chamber 1 is provided with two, the two rolling chambers 1 are arranged opposite to each other, and are respectively fixed on a wall (not shown), and a group of transmission components 2 are respectively provided in the two rolling chambers 1, the drive component 3 is arranged between the two rolling chambers 1, and the two ends of the drive component 3 respectively pass through the two rolling chambers 1 and are connected to the two transmission components 2, so as to drive the two groups of transmission components 2 to rotate, and the guide rail 4 is provided There are two guide rails 4 that are arranged opposite to each other, and the opposite sides of the two guide rails 4 are open. One ends of the two guide rails 4 are rolled and are respectively arranged in the two winding chambers 1. The other ends of the two guide rails 4 respectively penetrate the two winding chambers 1 and extend outward. There are two chains 5, which are arranged opposite to each other and are respectively movably arranged in the two guide rails 4, and are respectively engaged with the two transmission components 2, and are driven to slide in the guide rails 4 by the transmission components 2. A plurality of ropes 6 are arranged between the two chains 5, and the curtain 7 is arranged on the ropes 6 and is supported and fixed by the plurality of ropes 6. In the present utility model, through the cooperation of the driving component 3 and the transmission component 2, the chain 5 can be driven to be rolled up or extended outward along the guide rail 4 into the rolling chamber 1, and the rope 6 between the chains 5 can drive the curtain 7 to be rolled up or extended outward together. When the LED large screen needs to be shielded and protected by the curtain 7, for example, at night or on a rainy day, the LED large screen is not needed. The chain 5 can be driven to slide outward by the driving device and the transmission component 2 to drive the curtain 7 to unfold outward, thereby shielding the LED large screen and playing a protective role. When the curtain 7 needs to be stored, the chain 5 can be driven to slide into the rolling chamber 1 by the driving device and the transmission component 2 again to drive the curtain 7 to be rolled inward. The operation is convenient and it is convenient to protect the LED large screen next time to extend its service life.

[0033] like Figure 2 and Figure 4As shown, as a further solution, the transmission assembly 2 includes a driving wheel 201, a synchronous belt 202 and a driven wheel 203, wherein the driving wheel 201 and the driven wheel 203 are respectively rotatably arranged in the winding chamber 1, and the driving wheel 201 is connected to the driving assembly 3, the driven wheel 203 is connected to the driving wheel 201 through the synchronous belt 202, and the driven wheel 203 is engaged with the chain 5. Specifically, the driving wheel 201 is rotatably arranged at the center of one end of the guide rail 4 in a roll shape, and the driven wheel 203 is rotatably arranged in the winding chamber 1 and close to the guide rail 4. The driving wheel 201 is connected to one end of the driving component 3 and is driven by the driving component 3. The driving wheel 201 drives the driven wheel 203 to rotate through the synchronous belt 202, and the driven wheel 203 drives the chain 5 to move, and the positive and negative rotations of the driven wheel 203 can respectively drive the chain 5 to move along the guide rail 4 to the outside of the winding chamber 1 or to be wound into the winding chamber 1. When the two relative chains 5 move at the same time, the rope 6 between the two chains 5 drives the curtain 7 to unfold or roll up.

In this embodiment, the two driving wheels 201 are driven by a transmission shaft 302, so that the synchronous speed can be maintained, thereby ensuring that the moving speed of the two chains 5 is consistent when moving, so that the surface of the curtain 7 is flat when it is unfolded or retracted.

[0035] At the same time, the driving component 3 can also be composed of two motors 301 and two transmission shafts 302, one end of the two transmission shafts 302 is fixedly connected to a driving wheel 201 respectively, and the other ends of the two transmission shafts 302 are respectively connected to the two motors 301. If the driving component 3 includes two motors 301 and two transmission shafts 302, the two motors 301 need to be started at the same time when starting, and the power and speed are consistent.

[0036] In this embodiment, the other end of the guide rail 4 extends in a straight line or in an arc shape. Specifically, when the other end of the guide rail 4 extends in a straight line, the curtain 7 is a plane after unfolding, so the guide rail 4 with a straight line at the other end is suitable for a flat LED screen; when the other end of the guide rail 4 extends in an arc shape, the curtain 7 is an arc surface after unfolding, so the guide rail 4 with an arc at the other end is suitable for a LED screen with an arc surface.

[0037] As a further solution, a plurality of ropes 6 are evenly spaced between the two chains 5, and each rope 6 is connected to the back side of the curtain 7. Specifically, the smaller the distance between the ropes 6 between the two chains 5 and the higher the density of the ropes 6, the better the supporting effect on the curtain 7.

[0038] As a further solution, the two ends of each rope 6 are respectively bolted to the opposite sides of the two chains 5. The rope 6 is bolted to the chain 5 for easy disassembly. Since the rope 6 has a service life, it must be replaced later. The bolt connection makes it easy to replace or overhaul the rope 6.

[0039] In this embodiment, all the ropes 6 are steel cables, which have good corrosion resistance, a long service life, and are suitable for outdoor use.

[0040] like Figure 3 As shown, as a further solution, each of the ropes 6 is provided with a hook 8, and each of the hooks 8 is detachably connected to the back side of the curtain 7. Specifically, a ring or a buckle similar to a ring can be provided on the back side of the curtain 7 for hanging on the hook 8, so that the curtain 7 is hung on each rope 6. At the same time, the curtain 7 is made of any one of polyester fiber, polyurethane or polyvinyl chloride.

[0041] As a further solution, one end of the guide rail 4 in a roll shape is detachably arranged in the winding chamber 1. Specifically, one end of the guide rail 4 in a roll shape is arranged in the winding chamber 1, and the other end is a free end or detachably fixed to an object such as a wall or a bracket, and the guide rail 4 can be taken out of the winding chamber 1 for replacement.
