Description

Rolling Double-siders and Square Rolling Double-siders

technical field

The invention relates to a multi-sided flip, in particular to a rolling multi-sided flip and a phalanx rolling multi-sided flip.

Background technique

At present, the products used for advertising include picture-changing light boxes, which have the following disadvantages:

1. Large-scale advertisements cannot be realized: the maximum size is below 18 square meters;

2. There are 2 motors for the upper and lower reels, which drive the upper and lower reels respectively. The circuit is complicated and the cost is high;

3. If a lot of ordinary picture-changing light boxes are combined, due to structural limitations, the distance between the pictures of the two light boxes is very large, which seriously affects the effect of the picture;

4. In order to prevent the picture from being deformed by the wind, the light box has a glass cover to protect it, but it is impossible to completely protect it with glass for large outdoor advertisements.

In addition, products used for advertising also have rolling flips, which have the following disadvantages:

1. Generally, the picture ring structure is adopted (that is, the upper end of the first picture is connected with the lower end of the last picture), which is prone to picture deviation;

2. The picture will be deformed after being blown by the wind, so it cannot be used outdoors;

In addition, I once invented a large-scale scrolling advertising machine, but I used two wire ropes to drive the upper and lower reels. Because the logical direction of the two wire ropes plus the direction of the picture is very complicated, and because the winding direction of the wire rope is changing all the time, the operation It is very difficult and the failure rate is also high.

The tensioner pulley is connected with the second transmission wheel or the first transmission wheel; there is a pulley block between the drive shaft and the tensioner shaft, and the pulley block includes a fixed pulley, a lifting differential pulley and a belt rope. The fixed pulley is installed in the outer frame with relative rotation. The fixed pulley is located between the drive shaft and the retractable tension shaft. The two ends of the belt rope are fixedly connected with the drive shaft and the retractable tension shaft. fall.

The present invention is driven by a motor, the driving wheel drives the first transmission wheel, the upper reel rotates to unwind the advertising picture, the first transmission wheel runs in the opposite direction to the driving wheel, the retracting and tensioning wheel runs in the opposite direction to the second transmission wheel, and the first transmission The wheel and the second transmission wheel run in the same direction, and the retractable tensioner wheel rotates through the belt rope under the effect of the gravity adjustment pendant, and the tension of the advertising picture is realized by the lifting of the gravity adjustment pendant. While the motor is driving the first transmission wheel, the belt rope passes through the fixed pulley and the auxiliary pulley for retraction and expansion, and then moves the retraction and tensioner pulley to tighten the poster. Due to the gravity of the gravity adjustment pendant, the poster will Can always be in a tense state.

Advantage of the present invention has:

1. The screen can be automatically tightened, and the windproof effect is good;

2. The "rotational speed difference" caused by the continuous change of the diameter of the reel due to the different number of winding layers of the picture on the upper reel and the lower reel can be automatically adjusted, and the flipping effect is good;

3. One motor drive can realize the flipping of the screen, the circuit structure is simple, the failure rate is low, the cost is low, and it is easy to operate.
