This utility model discloses a slitting machine for processing printed velvet floor mats, including a support frame. A slitting mechanism is fixedly connected to the upper end of the support frame, and a cutting saw is fixedly connected to the bottom of the slitting mechanism. A fixed plate is fixedly connected to the lower end of the support frame. Multiple sets of first rotating shafts are movably connected to the outer side of the fixed plate, and the multiple sets of first rotating shafts are connected to each other via a second belt drive. Support legs are fixedly connected to the four corners of the bottom of the fixed plate. A pushing mechanism is installed on the upper end of the support legs, and a push plate is fixedly connected to one end of the pushing mechanism. A storage box is placed on the ground on one side of the push plate. The bottom of the cutting saw of this slitting machine for processing printed velvet floor mats is equipped with a bottom plate, which can more effectively cut the floor mats and prevent the conveyor belt from being cut, thus protecting the conveyor belt. At the same time, it can neatly collect the cut floor mats for easy transportation later.

This utility model relates to the field of civil defense door technology, specifically to a composite material civil defense door, comprising a door panel assembly, which includes a panel, a first fiber layer, and a filling layer. The panel is disposed outside the first fiber layer, and the first fiber layer is disposed outside the filling layer. The panel, the first fiber layer, and the filling layer are integrally formed. A reinforcing rib assembly is disposed on the panel to reinforce it. The reinforcing rib assembly includes a second fiber layer and an adhesive layer stacked together. The second fiber layer includes one or more of high-strength glass fiber cloth or glass fiber felt. The adhesive layer includes one or more of high-hardness unsaturated polyester resin, silica, and polyurethane foam board stacked together. The protective airtight door of this utility model reduces weight by 60%, has a simple product structure, increases production efficiency by more than 50%, facilitates subsequent transportation and on-site installation, and has good production efficiency and cost advantages.
