As a nutritional supplement, fish oil is rich in omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) and other beneficial ingredients for the human body. Edible fish oil has the effects of protecting the cardiovascular system, promoting brain development, anti-inflammatory, moisturizing the eyes, reducing anxiety and anti-depression. In the production process of fish oil, fish oil is obtained by squeezing the fish fat after cooking through a screw press. The screw press in the prior art includes a shell and a gradually shrinking spiral auger, the spiral auger is arranged in the shell, and a plurality of oil drain holes are provided on the shell. During the squeezing process, the fish fat is put into the large end of the spiral auger, and then the fish fat is transported forward by the spiral auger. Since the pitch and the inner diameter of the spiral auger are gradually reduced, under the cooperation of the shell, the transmission space will also be gradually reduced, thereby squeezing out the fish oil in the fish fat, and the fish oil will flow out of the outer shell through the oil drain hole, and the de-oiled fish fat will be discharged from the end of the shell. After the pressing is completed, a large amount of fish fat residue will adhere to the shell, the spiral auger and the oil drain hole and needs to be cleaned. However, due to the narrow space inside the shell, it is difficult to clean the fish fat residue inside the shell and the oil drain hole. Utility Model Content

A U-shaped frame 2 is fixedly arranged on the upper surface of the base 1. A hydraulic cylinder 10 is fixedly arranged at the top middle of the U-shaped frame 2. The telescopic end of the hydraulic cylinder 10 is fixedly connected with an arc-shaped convex seat 9. Avoidance openings 4 are arranged on the opposite side walls of the U-shaped frame 2. A free roller 6 and an electric roller 11 are respectively arranged in the two avoidance openings 4 on the left and right sides. The two ends of the free roller 6 are transferred to the opposite side walls of the avoidance opening 4. A support frame 15 is fixedly connected to the side wall of the oil collecting cylinder 5. The support frame 15 is fixedly arranged at On the upper surface of the base 1, the oil collecting cylinder 5 and the support frame 15 are both located in the middle of the inner side of the U-shaped frame 2. The top of the oil collecting cylinder 5 is provided with an arc-shaped recess 7, which is vertically aligned with the arc-shaped protrusion 9. The arc-shaped recess 7 is provided with a plurality of oil drain holes 8. Both ends of the free roller 2 13 are connected with sliding sleeves 21. The sliding sleeves 21 are provided with sliding rods 12 for sliding, so that the free roller 2 13 can rotate on the two sliding sleeves 21, and the free roller 2 13 can drive the sliding sleeves 21 to slide on the two sliding rods 12 respectively. The sliding rods 12 are fixed on the base 1, and an elastic mechanism is connected between the sliding sleeves 21 and the sliding rods 12. A conveyor filter belt 3 is connected between the free roller 16, the free roller 2 13 and the electric roller 11. The conveyor filter belt 3 is made of existing fabrics such as cotton cloth, polypropylene cloth or vinyl cloth. The electric roller 11 can drive the conveyor filter belt 3 to rotate, and the conveyor filter belt 3 drives the free roller 16 and the free roller 2 13 to rotate, so that the conveyor filter belt 3 is transmitted. The upper side of the conveyor filter belt 3 is located between the arc-shaped convex seat 9 and the arc-shaped concave seat 7. The oil collecting drum 5 is located on the inner side of the conveyor filter belt 3. When the arc-shaped convex seat 9 presses the conveyor filter belt 3 into the arc-shaped concave seat 7, the conveyor filter belt 3 pulls the free roller 2 13 upward from both sides. Under the action of the elastic mechanism, the sliding sleeve 21 overcomes the elastic force and slides upward on the sliding rod 12. When the arc-shaped convex seat 9 leaves the arc-shaped concave seat 7, the sliding sleeve 21 is driven to slide downward on the sliding rod 12 by the resilience of the elastic mechanism. The sliding sleeves 21 on both sides drive the free roller 2 13 to move downward from both sides. The free roller 2 13 pulls the conveyor filter belt 3 downward, so that the conveyor filter belt 3 is tightened on the motor roller 11, the free roller 1 6 and the free roller 2 13, so as to ensure that the motor roller 11 can drive the conveyor filter belt 3 to rotate on the motor roller 11, the free roller 1 6 and the free roller 2 13.
[0020] When squeezing fish fat, the utility model places the fish fat on the conveyor filter belt 3 between the arc-shaped convex seat 9 and the arc-shaped concave seat 7, and then drives the arc-shaped convex seat 9 to move downward through the hydraulic cylinder 10 to press the fish fat on the conveyor filter belt 3 into the arc-shaped concave seat 7, so that the fish oil is filtered by the conveyor filter belt 3 and then discharged from the oil drain hole 8, which can effectively squeeze and filter the fish fat. Under the action of the conveyor filter belt 3, the fish fat is prevented from being blocked in the oil drain hole 8. After the hydraulic cylinder 10 drives the arc-shaped convex seat 9 to rise and leave the arc-shaped concave seat 7, the conveyor filter belt 3 is used to move the squeezed fish fat to the outside of the electric roller 11, so that the fish fat can be continuously squeezed. Since the utility model is an open structure and has a simple structure, it is convenient to clean the fish fat residues on the arc-shaped concave seat 7, the arc-shaped convex seat 9 and the conveyor filter belt 3.
