The utility model discloses a guide plate structure of a steel ball rotary cutter. The guide plate structure comprises a mounting piece and a guide plate, an installation area is arranged on the installation part, an opening is formed in the lower end of the installation area, baffles are arranged on the two sides of the installation part, and a supporting section is formed at the opening. The guide plate is provided with an arc-shaped section, the arc-shaped section is arranged in the installation area through the opening, and the arc-shaped section is kept to be arranged on the supporting section. The guide plate structure of the steel ball rotary cutter moves downwards under the self weight of the guide plate by being matched with the mounting piece, so that the guide plate structure reaches a designated position and is matched with the spiral piece, and rolling of the steel ball is achieved. And meanwhile, during installation, the guide plate only needs to be rotated to be perpendicular to the installation piece, then the positioning section is arranged in the opening, and then the vertical section is rotated to be vertically parallel to the first vertical plate, so that rapid installation is achieved, the situation that the guide plate is located in a high-temperature area for a long time due to screwing of bolts is avoided, the personal safety of workers is guaranteed, and the working efficiency is improved.

The utility model relates to fireproof roller shutter door technical field discloses a kind of self-cleaning noise reduction mechanism of fireproof roller shutter door guide rail, including the limiting noise reduction piece being installed on the inner wall of fireproof roller shutter door guide rail notch and the cleaning piece for the self-cleaning of limiting noise reduction piece, limiting noise reduction piece and roller shutter side end contact, cleaning piece and limiting noise reduction piece contact. By setting the limiting noise reduction piece of roller shutter side end contact, the running track of roller shutter can be limited, and the friction noise between roller shutter and guide rail is reduced, by setting the contact of cleaning piece and limiting noise reduction piece, dust and sundries on the surface of limiting noise reduction piece can be automatically removed, to avoid pollutants affecting its performance, realize the self-cleaning and noise reduction double function of fireproof roller shutter door guide rail, improve the running stability and service life of roller shutter door.
