top structure: the transmission mechanism of the quick soft curtain door (quick rolling curtain door) is installed in the cabinet at the top of the door opening. The cabinet is made of galvanized steel plate with a thickness of 2mm, and both ends are made of steel plate with a thickness of 6mm. The end plate is provided with mounting seats and mounting holes for mounting the reel bearing, driving motor and balancing system components, and the surface of the steel plate is sprayed to the color required by customers. The reel is installed in the cabinet and consists of a reel, a shaft end and a bearing seat. The size of the drum is calculated according to the height and width of the door opening, and the reasonable size is selected. On this door, the diameter of the drum is 219 mm.
guide box: the guide box is made of 2mm-thick galvanized steel plate, which stands on both sides of the door opening and is fixed on the wall, while the chassis is placed on the top of the guide box and fixed on the guide box and the wall by bolts. Sealing tops are fixed on both sides of the guide groove of the guide groove box to ensure certain sealing requirements, and the installation position of the infrared monitor is reserved at the height of about 1m from the ground at the bottom of the guide groove box. The guide groove box is sprayed with plastic, which is the same color as the chassis. The brush in the inner part of the guide groove abuts against the curtain to prevent the curtain from leaving the guide groove, so that when the car hits the door, the door curtain will leave the guide groove, thus preventing the door from being damaged.
curtain cloth: the curtain cloth is made in sections, and the height of each section is about 7 mm. All the sections of curtain cloth are connected into a whole curtain cloth through special aluminum wind-resistant strips, and the curtain cloth is 1.2mm thick, which has the advantages of high strength, impact resistance, and difficulty in piercing. You can also use the transparent PVC material with δ=2mm to make the curtain or use some transparent PVC materials to make the curtain, so as to observe the situation on both sides of the soft curtain door. The bottom of the curtain is provided with an aluminum bottom beam, and the top of the curtain of the anti-collision soft bag is fixed on the drum through screws and layering.
drive device: the shaft of the soft curtain door is directly driven by the reduction motor, and reducers with different speed ratios are selected according to the requirements of lifting speed to achieve the required lifting speed, and the fastest speed can reach more than 2 px/s. The control circuit adopts frequency conversion control, so that the curtain cloth can start slowly and stop slowly during operation, and the curtain cloth can stop automatically when it is in place and stop moving during operation.
control: the soft curtain door is equipped with a control box, which can be operated on "on", "off" and a control button can be set on the other wall of the control box to operate "on", "off". Remote control operation and radar detection or geomagnetic induction automatic door opening and closing can be selected as required, and infrared monitoring devices are installed at both sides of the door opening. When an obstacle passes through the door opening when the door body moves, the curtain movement will stop or return to the door opening state. ?
