Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrimp vein removal technology, specifically to an automatic shrimp vein removal device. Background Technology
[0002] With the continuous expansion of the seafood market and the increasing demands of consumers for food quality, the processing needs of shrimp and other seafood products are also growing. Traditional manual shrimp deveining methods are inefficient and cannot meet the needs of large-scale production. Therefore, the market demand for automated shrimp deveining equipment is becoming increasingly urgent.
[0003] In existing technologies, the bending and pulling method is used to remove the shrimp vein. This method first uses a bending and squeezing system to bend the shrimp head and squeeze out the shrimp brain, then uses an automatic pulling system to grasp the shrimp brain and pull the shrimp vein out of the shrimp body. Its operation does not rely on complex cutting or precise positioning; only the bending force and gripping action need to be controlled to quickly remove the shrimp vein. It is widely applicable to shrimp of different sizes and can better maintain the integrity of the shrimp body, reducing shrimp meat loss.
[0004] During the process of bending and squeezing the shrimp head to extract the shrimp brain, improper force control may still cause internal damage to the shrimp body, affecting the quality of the shrimp. Especially for some more fragile shrimp species, the shrimp vein may break during the process of pinching the shrimp brain and pulling out the shrimp vein, resulting in some shrimp vein remaining in the shrimp body, which cannot be completely removed, affecting the hygiene quality of the shrimp and making it impossible to efficiently remove the shrimp vein. To address the above problems, an automatic shrimp vein removal device is proposed. Utility Model Content

The two ends of the top side of the base plate 1 are fixedly connected to the first support column 2, and the top of the first support column 2 is fixedly connected to the funnel 3.
[0032] Reference Figure 2 and Figure 3 The base plate 1 has brackets 4 fixedly connected to both ends of the top center. A conveyor belt 5 is fixedly connected to the top of the brackets 4. The brackets 4 can stably support the conveyor belt 5, and the conveyor belt 5 can facilitate the transportation of shrimp.

[0033] Working principle: First, a funnel design (3) is used to facilitate the user in placing the shrimp to be processed into the funnel. Then, the shrimp are transported via a conveyor belt (5) equipped with two infrared detectors (7) to detect the length of the shrimp and determine their size. After detection, a second motor (16) drives a second lead screw (14) to rotate, and a clamping plate (17) holds the shrimp, ensuring its back is facing down for further processing. At this point, an Arduino microcontroller (23) controls a single-chip motor (18) with spiral blades (19) to precisely cut the shrimp's back. For large shrimp, the single-chip motor (18) can cut more precisely. The cutting machine program will cut the blade upward by one millimeter based on the data from the infrared detector 7 to ensure that the shrimp back can be completely cut open. After cutting, the shrimp will be rinsed by the water gun 20 to thoroughly remove the shrimp vein. Finally, the processed shrimp will be rotated by the first motor 10 driving the first lead screw 11, which will cause the slide plate 13 to move the clamping plate 17 and the transfer plate 24 to the top of the holding frame 21, and send the shrimp into the storage basket. This product realizes the fast, efficient and accurate removal of shrimp vein through automation technology, which greatly improves the production efficiency and quality of shrimp processing.
