The invention discloses a material storage mechanism with a direction detection module. The material storage mechanism comprises a material storage bottom plate provided with a discharge groove, material storage vertical plates fixedly arranged on the portions, on the left side and the right side of the discharge groove, on the material storage bottom plate respectively, a separation module arranged on the material storage bottom plate and used in cooperation with the discharge groove, and the direction detection module arranged on the material storage bottom plate and corresponding to the discharge groove. The direction detection module comprises a detection cylinder support arranged on the material storage bottom plate, and a direction detection cylinder arranged on the detection cylinder support, and a direction detection probe is connected to a cylinder shaft of the direction detection cylinder. Compared with the prior art, the material storage mechanism has the advantages that the direction of a material plate, at the lowest end, stored in the material storage mechanism can be automatically detected without allocating additional personnel for manual assistance, and the production efficiency is improved.
