A chute 30 is arranged on the opposite side of the two groups of mounting brackets 3, and a first stepping motor is arranged on the top of the chute 30
The first travel switch 31 that machine 6 connects, the linking bridge 10 is installed at the both ends of blade 1, the last wheel 11 that rotates of linking bridge 10 is installed, wheel 11 is located the spout 30 and rolls the motion, drive the first rope 2 that winds at dwang 60 at first step motor 6 and make blade 1 rise to draw in or descend to scatter and make, because blade 1 both ends pass through linking bridge 10 drive wheel 11 up-and-down motion in spout 30, this motion is roll connection, so greatly reduced the frictional force that produces when blade 1 and installing support 3 relative motion, make blade 1 lift more easily, and owing to set up spout 30, so blade 1 goes up and down very steadily, can not take place horizontal displacement.
The third rope 8 is provided with a clamping block 80, a notch 81 is formed in the clamping block 80, the front face of each blade 1 is matched with the notch 81 in a clamping manner, when the front end of each blade 1 is driven by the second stepping motor 7 to change in opening and closing angle so as to realize the dimming function, the clamping block 80 is provided with the notch 81, the notch 81 is matched with the front face of each blade 1 in a clamping manner, and therefore the third rope 8, namely the first annular rope, on which the second stepping motor 7 is driven is used for rotating each blade 1 by taking the connecting support 10 as a fulcrum, the opening and closing angle of each blade 1 is changed, and the dimming function is realized.
The bottom of the fixed plate 5 is embedded with a second travel switch 50 connected with a second stepping motor 7 at the penetrating position of a third rope 8, the uppermost clamping block 80 is in point contact with the second travel switch 50, when the second stepping motor 7 drives a first annular rope to pull the front of the blade 1 upwards, the second travel switch 50 is used for limiting the uppermost clamping block 80, and when the uppermost clamping block 80 is contacted with the second travel switch 50, the second stepping motor 7 can be controlled in a power-off mode, and damage to a shutter caused by overdriving of the second stepping motor 7 is prevented.
The first pulley 9 and the second pulley 90 are coaxially sleeved on the round rod 91 through bearings, the round rod 91 is installed at the bottom between the two groups of installation supports 3, the first annular rope is driven by the second stepping motor 7 or the second annular rope is driven manually, the front end opening and closing angle change of the blade 1 is achieved, and then the dimming function is achieved.
The driving gear 70 is sleeved on the second stepping motor 7 in a rotating manner, the tooth groove 82 is formed in the first annular rope, the first annular rope is in linkage with the driving gear 70 through the tooth groove 82, and the first annular rope is in linkage fit with the driving gear 70 through the tooth groove 82, so that movement can be more accurate, slipping is avoided, and accordingly lifting speed is increased.
The blade 1 is made of glass fiber and is made into a finely synthesized cloth-type shutter with waterproof, fireproof and ultraviolet-proof materials, and in order to make the whole shutter curtain lighter, the mounting bracket 3, the first pulley 9, the connecting bracket 10, the wheels 11, the driving gear 70, the clamping blocks 80, the second pulley 90, the round rods 91 and the like can be made of polypropylene or PVC plastic, and the first stepping motor 6 and the second stepping motor 7 are 12SSN20 miniature gear motors, so that the size is small, the power consumption is low, and the power is high.
The first stepping motor 6 and the second stepping motor 7 are also connected in series with an emergency stop switch, the emergency stop switch is arranged on the switch 12, and when an emergency occurs, the first stepping motor 6 and the second stepping motor 7 can be powered off through the emergency stop switch, so that the shutter curtain is prevented from being damaged.
When the intelligent dimming device is used, the first stepping motor 6 and the second stepping motor 7 are electrified, then the first stepping motor 6 is respectively controlled by the switch 12 to rotate forwards and backwards through the driving rotating rod 60, the purpose of driving the two groups of first ropes 2 to pull up and fold the blades 1 in an electric telescopic regulation and control mode is achieved, then the second stepping motor 7 is controlled to drive the front end of the blades 1 to change in opening and closing angles through the driving of the third ropes 8, the dimming function is achieved through the driving of the clamping blocks 80 on the third ropes 8 in an electric telescopic regulation and control mode, the second ropes 20 can be pulled manually to pull up and fold the blades 1, and the dimming function is achieved through the driving of the clamping blocks 80 on the other group of the third ropes 8 in a manual telescopic regulation and control mode to drive the front end of the blades 1 to change in opening and closing angles.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
