Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a silent rolling door for a clean room comprises an outer cover 1, a motor 2, a scroll 3, a curtain cloth 4 and a slideway 5, wherein the motor 2 is fixedly installed inside the outer cover 1, the motor 2 drives the scroll 3 to rotate through a chain, the side surface of the scroll 3 is fixedly connected with one side of the curtain cloth 4, two sides of the curtain cloth 4 in the vertical direction are movably clamped inside the slideway 5, and the curtain cloth 4 can move up and down by the rotation of the scroll 3. The equal fixed mounting in the part of the limit portion of

curtain cloth

4 and 5 joints of slide has electro-magnet 6, electro-magnet 6 is a plurality of and arranges neatly, electro-magnet 6 establishes ties with motor 2, the internal surface fixed mounting of the both sides slide 5 of electro-magnet 6 has magnet I7 and magnet II 8, electro-magnet 6 all is homopolar with the adjacent face of magnet I7 and magnet II 8, electro-magnet 6 and slide 5 contactless under the repulsion effect during the circular telegram, thereby there can not be noise and resistance, consequently power saving more.

Wherein, a sealing strip 9 is fixedly arranged on the surface of one side of the electromagnet 6 facing the magnet I7, the sealing strip 9 is made of rubber, a sliding block 10 is fixedly arranged under the sealing strip 9, the surface of one side of the sliding block 10 has a slope, a guide block 11 is fixedly arranged in the slide way 5 under the sliding block 10, the inclined plane of the guide block 11 is parallel to the inclined plane of the sliding block 10, so that the sliding block 10 slides rightwards when contacting with the guide block 11, the electromagnet 6 at the lowest end is driven to approach the sealing strip 9 rightwards, the motor 2 is automatically powered off when the curtain cloth 4 moves downwards to the lowest end, the repulsion force of the electromagnet 6 disappears, at the moment, under the action of the sliding block 10 and the guide block 11, the bottom end of the electromagnet 6 is closer to the magnet I7, therefore, the electromagnet 6 is sequentially attracted with the magnet I7 from bottom to top under the interlocking reaction, and the sealing strip 9 is contacted with the magnet I7, so that the sealing effect is better.

The slider 10 and the guide block 11 are permanent magnets, and the opposite surfaces are homopolar, so that noise and resistance can be reduced to the maximum extent.

Wherein, the inside of dustcoat 1 is provided with soundproof cotton for absorb the noise that the motor 2 produced when moving altogether.

Since the current of the motor 2 changes its direction when it rises and falls, and the current of the electromagnet 6 cannot change its direction, a bridge rectifier circuit is applied to this, specifically (as shown in fig. 5), a main circuit is connected between the motor 2 and one end of the power supply, a branch circuit is connected between the two ends of the rectifier diode, and the electromagnet 6 is connected to the branch circuit, so the current direction of the electromagnet 6 is always kept unchanged. The mode that the power supply supplies positive and negative electricity to the circuit is controlled by the remote switch.

The use method (working principle) of the invention is as follows:

this silence rolling slats door only need press the switch, electro-magnet 6 will be circular telegram with motor 2, motor 2 rotates and drives 3 rotations of spool, realize the lift of curtain cloth 4, curtain cloth 4 convolutes on the spool when rising, curtain cloth 4 slides down along slide 5 inboards when descending, because electro-magnet 6 is homopolar with the magnet I7 in the slide 5 and the face in opposite directions of magnet II 8, electro-magnet 6 does not take place the contact with magnet I7 and magnet II 8 under the repulsion effect, consequently, there is not frictional force between curtain cloth 4 and the slide 5, just can not produce the noise, according to the law of conservation of energy, the resistance reduces between curtain cloth 4 and the slide 5, corresponding motor 2's energy consumption also can reduce, consequently, power saving more. When the curtain cloth 4 slides to the bottom, under the action of the sliding block 10 and the guide block 11, the bottom of the electromagnet 6 is close to the magnet I7, meanwhile, the motor 2 is powered off at the maximum stroke, and the repulsive force of the electromagnet 6 disappears, so that the electromagnet 6 is sequentially attracted with the magnet I7 from bottom to top under the chain reaction, and the sealing strip 9 is in contact with the magnet I7 at the moment, so that the sealing effect is better.
