Mute zipper door with automatic sealing mechanism

The invention relates to the technical field of roller shutter doors, in particular to a mute zipper door with an automatic sealing mechanism, which comprises an aluminum alloy section straight rail, a zipper door box fixed at the upper end of the aluminum alloy section straight rail, a tubular motor mounted in the zipper door box and an aluminum alloy section bottom beam fixed at the bottom of the aluminum alloy section straight rail. According to the silent zipper door with the automatic sealing mechanism, an external telescopic rod with a guide roller installed outside is elastically assembled on a cylindrical transverse control frame of a rotary silent rolling frame, so that collision with a motor can be avoided when a roller shutter is quickly started, and the safety, durability and silence performance are improved; a screw overturning type extrusion mechanism used for improving the assembling sealing performance of the flexible roller shutter mechanism is movably assembled in the aluminum alloy section
