The present utility model discloses a material accumulation alarm device for a twin‑screw extruder, comprising a hopper, an infrared sensor, a camera and a high‑pressure air nozzle. The infrared sensor includes a transmitter and a receiver, installed opposite the outer side of the bottom of the hopper, with infrared rays passing through the discharge port of the hopper. The camera is located above the middle of the hopper and faces the discharge port of the hopper. The high‑pressure air nozzle is located above the infrared sensor, and its high‑pressure air nozzle is connected with an external air pipe, which can be purged by compressed air in case of slight material accumulation. It also includes a control box comprising an alarm, a display screen and a power switch. The control box is connected with the camera, and the display screen can monitor the real‑time picture of the discharge port of the hopper through the camera. The control box is connected with the infrared sensor. When material accumulation and blockage occur at the discharge port of the hopper, the alarm sends an alarm signal through the blocked infrared rays emitted by the infrared sensor to remind timely treatment and avoid the risk of screw jamming and equipment damage.
