[0002] The existing electric stage transmission is to transmit motion through the friction between the steel wire and the V-groove transmission wheel, and the steel wire drives the pulley to move on the track; however, during the transmission process of the existing stage, the steel wire must be tightened very tightly to prevent the steel wire and the transmission wheel from appearing. Slip reduces the load of the system, and the system can only work below 17 meters; the steel wire is easily broken due to long-term tension and frictional movement; the steel wire cannot bend and move, and in the track, after the steel wire is tightened, it will form a straight line that is completely close to the track Friction increases the load of the system, exceeding the load capacity of the motor and failing to work

Embodiment 1
[0027] A stage curtain opening and closing device, such as figure 1 As shown, a track 7, a motor, a transmission mechanism and a pulley 5 are provided, and the motor drives the pulley 5 to move through the transmission mechanism. The transmission mechanism includes a main gear 3, a driven gear 6 and a synchronous belt 4, and the synchronous belt 4 is wound around The motor is drivingly connected to the main gear 3 and the driven wheel, and the synchronous belt 4 moves along the track 7 .
[0028] The transmission mechanism of the present invention transmits power movement through the meshing of the toothed belt and the gear, and the toothed belt and the gear are closely connected, so there is no relative sliding between the toothed belt and the gear, which can ensure an accurate transmission ratio, ensure stable transmission, and increase transmission efficiency. The load capacity of the mechanism is that the longest track 7 is 30 meters long;
[0029] The synchronous belt 4 ...

The invention discloses a stage curtain opening and closing device. The stage curtain opening and closing device is provided with a rail, a motor, a transmission mechanism and a pulley, wherein the motor drives the pulley to move through the transmission mechanism; the transmission mechanism comprises a main gear, a driven gear and a synchronous belt; the synchronous belt surrounds the main gear and the driven gear; the motor is in driving connection with the main gear; the synchronous belt moves along the rail. The transmission mechanism is meshed with the gears through a toothed belt, so as to transfer power, and the toothed belt is tightly connected with the gears, so that the toothed belt and the gears cannot slide relative to each other, accurate transmission ration can be guaranteed, stable transmission is guaranteed, the carrying capacity of the transmission mechanism is increased, and the longest rail reaches 30 meters; the frictional force between the synchronous belt made of rubber and the metal rail is small, so that the tighten up force of the synchronous belt is smaller than that of a steel wire, and the load of the motor is reduced; the synchronous belt can move with grooves in the two sides of the rail.
Description
technical field [0001] The invention relates to the technical field of outdoor products, in particular to a stage curtain opening and closing device. Background technique [0002] The existing electric stage transmission is to transmit motion through the friction between the steel wire and the V-groove transmission wheel, and the steel wire drives the pulley to move on the track; however, during the transmission process of the existing stage, the steel wire must be tightened very tightly to prevent the steel wire and the transmission wheel from appearing. Slip reduces the load of the system, and the system can only work below 17 meters; the steel wire is easily broken due to long-term tension and frictional movement; the steel wire cannot bend and move, and in the track, after the steel wire is tightened, it will form a straight line that is completely close to the track Friction increases the load on the system, exceeding the load capacity of the motor and failing to work. ...
