Automatic weighing apparatus type evaluation test device

The utility model relates to the field of automatic weighing instruments, in particular to an automatic weighing instrument type evaluation test device which comprises a test box body, a door frame is fixedly connected to one side of the test box body, a sliding door is slidably connected to the interior of the door frame, supports are fixedly connected to the two ends of the test box body, and air cylinders are installed at the top ends of the supports. The output end of the cylinder is fixedly connected with a standard sensor, and an infrared distance measuring sensor is mounted at the top end of the test box body on one side below the cylinder. According to the utility model, the test simulation device can be quickly placed in the middle, the side marker post can be pulled to be flush with a to-be-applied load point of the test simulation device, and then the test platform is pushed into the test box body until the infrared distance measuring sensor measures the top end of the side marker post, so that the
