Agent: Dong Jinguo Abstract The utility model relates to a large bank note flattening device for a securities offset printing printing quality detector, which has a negative pressure cabin. Suction plate, a uniform pressure plate with vent holes on the suction plate, and a flat plate arranged on the pressure plate, and the upper end of the flat plate A suction hole is evenly provided, and a negative pressure chamber is arranged at the lower end of the flat plate. The suction hole communicates with the negative pressure chamber. The negative pressure chamber on the flat plate passes through the vent hole on the pressure plate and the negative pressure on the suction plate. The chambers are connected and the negative pressure cabin on the suction plate communicates with the fan through the suction holes. The utility model is applied to the RMB offset printing quality detection instrument, and the utility model is very simple, adopts the pneumatic negative pressure flattening method, and has a large exhibition surface. , notes adsorption and removal speed and so on. Sovereignty item 1. A large-area flattening device for printing paper, characterized in that it comprises a suction plate (5) with a negative pressure chamber (6), a ventilation hole provided on the suction plate (5) ( 4) The pressure plate (3) and the flat plate (1) provided on the pressure plate (3), and the upper end of the flat plate (1) is evenly provided with a suction hole (2), and the lower end of the flat plate (1) is set. There is a negative pressure chamber (9), the suction hole (2) and the negative pressure chamber (9) communicate with each other, and the negative pressure chamber (9) on the flat plate (1) passes through the air hole (4) on the pressure plate (3). It communicates with the negative pressure chamber (6) on the suction plate (5). The negative pressure chamber (6) on the suction plate (5) communicates with the fan through the suction hole (8).

A wooden crate has a self-supporting structure, with or without sheathing. For a wooden container to be a crate, all six of its sides must be put in place to result in the rated strength of the container. Crates are distinct from wooden boxes. The strength of a Wooden Box is rated based on the weight it can carry before the top (top, ends, and sides) is installed, whereas the strength of a crate is rated with the top in place. In general conversation, the term crate is sometimes used to denote a wooden box.

Although the definition of a wooden crate, as compared to a wooden box, is clear, construction of the two often results in a container that is not clearly a crate or a box. Both wooden crates and wooden boxes are constructed to contain unique items, the design of either a crate or box may use principles from both. In this case, the container will typically be defined by how the edges and corners of the container are constructed. If the sheathing (either plywood or lumber) can be removed, and a framed structure will remain standing, the container would likely be termed a crate. If removal of the sheathing results in no way of fastening the lumber around the edges of the container, the container would likely be termed a wooden box.
