[0002] The shredder plays a vital role in the tobacco processing process. The shredder can cut tobacco into shredded tobacco. Testing the feeding before shredding can ensure the quality and uniformity of the shredded tobacco.

[0003] Before the conventional shredding operation, tobacco is delivered to the entrance of the shredder by a feeding trolley, and then the upper and lower copper chains at the entrance of the shredder compact the tobacco, and the compacted tobacco is quickly cut into shredded tobacco required by the production process by the blades on the cutter roller of the shredder. However, the entrance of the existing shredder is not equipped with a device that can detect the material entering the shredder. If a person mistakenly enters the shredder feeding trolley and is transported to the shredder, the operator at this time is easily injured by the upper and lower copper chains or the shredder.
