Description

Fish body posture restraining mechanism for fish bloodletting Technical Field The utility model relates to the technical field of fish product processing machinery, in particular to a fish body posture restraining mechanism for fish bloodletting. Background China is a large country of aquaculture, the total yield of aquatic products in 2023 China reaches 7116.17 ten thousand tons, and the total amount of aquatic products for processing is 2623.71 ten thousand tons. The manual processing mode can not meet the requirement of large-scale production, and the processing of high-quality, high-efficiency and mechanical aquatic products becomes a necessary requirement. At present, the pretreatment process of aquatic product processing in China has higher manual participation degree, is weak in technology as a whole and low in mechanization degree, still depends on manual work in key links, and belongs to labor-intensive industries. Therefore, the development of the key technical equipment for pretreatment of the aquatic products has important practical significance. Killing fish and bleeding are key steps of fish pretreatment. During the processing of the fish fillets, hemoglobin in blood remains in muscle tissues without bloodletting treatment, so that the brightness value of the fish meat is reduced, and the color of the fish meat becomes dark. Thus, hemoglobin residues can cause discoloration of the fish meat, and the bleeding treatment can cause the fish fillet to take on a whiter appearance. The fish meat subjected to the bleeding treatment has less fishy smell, and is beneficial to improving the taste and quality of the fish meat. In the conventional bloodletting process, a knife is pricked at the lower edge of the gill cover at two sides to cut the throat, and then the fish is put into clear water to swim. Blood in the fish body can accelerate to flow out of the body in the process of free swimming, so that the residual blood in the fish body is minimized. Taking snakehead (snakehead) slices as common raw materials for dishes such as pickled fish, boiled fish and the like as an example, bleeding is the first process link of snakehead slice production. The processing amount of finished black fish slices in China is about 50 ten thousand tons at present, and the market demand of mechanical bloodletting basically depends on manual bloodletting is huge. The domestic research on fish processing mainly focuses on links such as orientation, scale removal, head removal, viscera removal, peeling and the like, and related reports of fish bloodletting technical equipment are not found at present. The domestic bloodletting link completely depends on the manual hand-held cutter to carry out bloodletting treatment, the fish killing bloodletting method also depends on the experience of workers, and a standardized operation process is not formed, so that the processing mode has low efficiency, high labor intensity and certain danger, and therefore, the domestic fish killing bloodletting link is in an inorganic available state, and practical equipment with strong adaptability is needed in the market. When the equipment for killing fish and exsanguinating is developed, the posture of the live fish is required to be restrained and limited so as to adapt to the technological requirements of fish throat cutting and exsanguinating, and therefore, a fish body posture restraining mechanism for fish exsanguinating is required to be developed. Disclosure of utility model The utility model provides a fish body posture restraining mechanism for fish bloodletting, which prevents the posture of fish from deflecting and creates conditions for automatic bloodletting. The utility model adopts the following technical scheme: The fish body posture restraining mechanism for fish bloodletting comprises a V-shaped restraining channel, a cover plate arranged at the top of the channel, a supporting bottom plate arranged below the bottom of the channel and a plurality of spring groups, wherein through holes are formed in two side plates of the V-shaped restraining channel, one end of each spring is fixedly connected to the supporting bottom plate, the other end of each spring passes through the through holes and is fixed to top flanges of the two side plates, and the top flanges of the two side plates extend oppositely, so that a part of each spring is contained in the V-shaped restraining channel; The two side plates of the V-shaped constraint channel are symmetrically provided with springs to form spring groups, the distance between the two springs of the spring groups is smaller than the maximum distance between the two sides of the fish body, and the spring groups are arranged at intervals in the passing direction of the V-shaped constraint channel. Further, the cover plate is not covered above the channel for fixing the position of the fish head, or the cover plate is covered by the V-shaped constraint channel corresponding to the position of
