[0002] Fiberglass gas collection hoods are mainly used to collect waste gases generated during industrial production processes, such as waste gases from chemical, metallurgical, and power industries, and guide them to waste gas treatment equipment for purification, thereby reducing the emission of harmful gases.

[0003] In the prior art, such as the Chinese announcement number CN213052012U, a printing press exhaust gas collection hood includes a housing. A driving mechanism is located at the rear of the top of the housing's inner cavity. Anti-sway mechanisms are vertically arranged on both sides of the housing's inner cavity. An exhaust pipe is installed within the housing's inner cavity, and its bottom extends through to the bottom of the housing and is fixedly connected to the exhaust hood. This invention, through the coordinated arrangement of the housing, driving mechanism, anti-sway mechanism, exhaust pipe, exhaust hood, opening, exhaust fan, fixing block, bearing seat, slide groove, slider, fixing plate, and fixing hole, achieves the advantage of adjustable operating height. This solves the problem of existing printing press exhaust gas collection hoods being unable to adjust their operating height. When using the printing press exhaust gas collection hood, it can be moved upwards or downwards according to the gas collection needs, effectively meeting the process requirements of the printing equipment and providing convenience for users.

[0004] The aforementioned application achieves the effect of adjustable height for the gas collection hood through multiple components. However, the device is not easy to achieve effective protection and may be damaged when subjected to impact, which reduces the overall convenience and timeliness to some extent.
