Rapid detection frame for processing size of tray

The utility model relates to the technical field of detection frame equipment, in particular to a rapid detection frame for the processing size of a tray. Comprising a feeding assembly, a discharging assembly, a limiting assembly, a frame body assembly and a detection assembly, the output end of a telescopic rod is connected with a limiting vertical plate, the inner ring of a sliding clamping block is connected with a positioning rod, the detection assembly comprises a linkage plate, one end of the linkage plate is connected with the sliding clamping block, and the other end of the linkage plate is connected with the frame body assembly. The end, away from the sliding clamping block, of the linkage plate is connected with a detection transverse plate. The tray thickness detection device has the advantages that when the linkage plate is driven by the sliding clamping block to move, the linkage plate drives the detection transverse plate to move synchronously in the moving process, the height from the detection
