Description

Technical Field

[0001] This invention belongs to the technical field of shrimp deveining machines, specifically relating to a shrimp deveining machine and its usage method. Background Technology

[0002] A shrimp deveining machine is a specialized machine designed to remove the vein from shrimp, improving the efficiency and quality of seafood processing. These machines are typically equipped with robotic arms or blades to automate the peeling and deveining process.

[0003] A search revealed a Chinese patent (CN110402997B) disclosing an automatic shrimp vein removal device and its usage method. This device automatically removes the shrimp vein based on a detection device, a loading system, and a feeding system. First, the shrimp is positioned and clamped on the loading system. Then, under strong light, a miniature camera takes a picture to identify the position of the shrimp vein. A combination of blades then cuts open the shrimp's back according to the generated blade trajectory, simultaneously automatically extracting the shrimp vein. This invention uses a flexible clamping method to position and clamp the shrimp, adapting to shrimp of different shapes and sizes. The strong light makes it easier to locate the shrimp vein. The optimized design of the combination blades improves the force direction during the shrimp vein extraction process, making it easier to remove the shrimp vein, and also has an anti-clogging function.

[0004] However, the above-mentioned technical solutions improve the force direction during the shrimp vein extraction process, making the shrimp vein easier to extract, and also have an anti-clogging function. However, in the existing technology, when removing the shrimp vein from shrimp, the shrimp vein is not removed completely, resulting in some shrimp vein remaining at the shrimp tail, which in turn affects the processing efficiency.
