Description

Technical Field

[0001] This utility model relates to the field of fish processing technology, specifically a fully automatic fish descaling and viscera cleaning device. Background Technology

[0002] As the scale of the fishery continues to expand, primary processing of aquatic products (such as scaling, gutting, and cleaning fish) still relies mainly on manual labor. This method is inefficient, costly, and produces inconsistent quality. Existing equipment generally has limited functionality and cannot meet the demands of large-scale processing. However, the increasing maturity of mechanical structure technology has made automation in fishery processing a realistic possibility.

[0003] Currently, fish visceration and descaling machines are available in China, replacing traditional manual methods of descaling and visceration, thus improving processing efficiency and reducing labor intensity. However, current fish processing facilities in China have relatively limited functionality and poor adaptability to different fish types. Most facilities separate the descaling and devising processes, resulting in poor continuity.

[0004] Existing fish descaling and eviscerating machines mainly consist of a descaling mechanism, an evisceration mechanism, and a conveying mechanism. Regarding the descaling mechanism, Chinese patent CN218245448U discloses a fish descaling mechanism that is easy to clean, using nylon bristles on the brush body to brush off fish scales attached to the descaling roller. Chinese patent CN201029397Y discloses a fish processing machine for removing fish scales, evisceration, and black membrane, employing a high-pressure water evisceration method.

[0005] While the aforementioned technical solutions can achieve descaling and eviscerating of fish, the former uses a nylon brush for scaler removal, and the continuous friction during the process shortens the brush's length, affecting its lifespan. The latter uses high-pressure water to remove viscera, increasing energy consumption. Furthermore, some traditional descaling mechanisms on the market lack a clamping mechanism designed to keep the fish stable during the descaling process. Utility Model Content

[0006] In view of the technical problems existing in the prior art, this utility model proposes a fully automatic fish descaling and viscera cleaning mechanism. Compared with traditional equipment on the market, it ensures the continuity of the descaling and viscera removal process, achieves better descaling and viscera removal results, and improves work efficiency.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a fully automatic fish descaling and eviscerating device, comprising a frame, a clamping mechanism and a descaling mechanism, an abdominal opening and eviscerating mechanism, a pushing mechanism, and a waste collection box.

[0008] The clamping mechanism is installed at the front end of the frame. The clamping mechanism includes a pair of pressure plates arranged opposite each other and a spring assembly connected to the pressure plates. The spring assembly is adjustablely installed on the side plate by a nut to elastically clamp the fish and adapt to different thicknesses. The descaling mechanism is located above the clamping mechanism. The descaling mechanism includes: a servo motor fixed to the second bracket, an eccentric wheel installed at the output end of the servo motor, a first slide rail and a slider. The slider slides in cooperation with the first slide rail. The slider is connected to the scaler through the spring assembly. The eccentric wheel drives the slider to reciprocate along the first slide rail through a roller so that the scaler fits against the surface of the fish to remove scales.

[0009] The evisceration and abdominal opening mechanism is located below the descaling mechanism. The evisceration and abdominal opening mechanism includes: a second cylinder fixed to the frame and inclined at a 10° angle to the frame, and an abdominal opening knife connected to the output end of the second cylinder, so as to separate the internal organs from the fish body while opening the abdomen.

[0010] The pushing mechanism is used to push the fish body from the feeding port into the clamping mechanism and push it out of the discharge port after processing; the waste collection box is located directly below the descaling mechanism and the evisceration mechanism, and is used to collect fish scales and viscera simultaneously.

[0011] The scraper blade has serrated teeth and an arc-shaped cutting edge, and is detachably connected to the second connecting plate by bolts to achieve modular replacement.

[0012] The spring assembly is configured to adjust the spacing between the pressure plates within the range of 2 cm to 40 cm by rotating the nut.

[0013] The servo motor has multiple adjustable speeds to allow the reciprocating frequency of the scaler to adapt to different fish species.

[0014] The pushing mechanism includes: a first cylinder fixed to the frame, a pair of baffles that limit the path of the fish into the clamping mechanism, one end of the output end of the first cylinder is connected to a push rod, and the other end of the push rod is provided with a push block.

[0015] The frame is 40 cm high and 120 cm long, and is made of solid material to ensure processing stability.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Spring assemblies are incorporated into the clamping and scaling mechanisms. The elastic compression of the springs allows the pressure plate and scaling blade to conform to different fish bodies, thus improving the fit. The clamping force can be adjusted by rotating the nut to ensure the stability of the fish during processing.

[0018] 2. The descaling mechanism is driven by an eccentric wheel, and the blade reciprocates on the guide rail. The scaler is connected to the connecting plate by a spring assembly, which reduces damage to the fish during the descaling process.

[0019] 3. After the fish to be processed are placed in the feed, all mechanisms start automatically. The entire processing process requires no manual intervention, greatly improving the automation level of the equipment and helping to save manpower and increase efficiency. This utility model is equipped with a waste collection box to ensure a clean processing environment.

[0020] 4. Modular design allows for individual replacement of each part. The descaling blade can be quickly replaced via bolt connection.

[0021] 5. In the abdominal dissection and visceration mechanism, the abdominal dissection blade is tilted at a 10-degree angle to the frame, so that the internal organs are separated from the fish body while the blade is feeding during the abdominal dissection process, thus avoiding the need to design a separate visceration mechanism.

The servo motor 7 is bolted to the second bracket 8, and the second bracket 8 is bolted to the fourth base plate 33 of the side plate 14. The side plate 14 is bolted to the frame, and the first slide rail 15 is bolted to the fourth base plate 33. The blade 13 is welded to one end of the spring assembly 12. The scraping blade 13 is connected to the second connecting plate 19 via the nut 18. The distance between the scraping blade 13 and the center groove can be adjusted by rotating the nut 18. The scraping blade 13 has serrated teeth and a certain curvature. The second connecting plate 19 is welded to the slider 17 and the second guide rail 10. The servo motor 7 drives the eccentric wheel 9 to rotate. The eccentric wheel 9 is converted into the reciprocating motion of the scraping blade 12 and the slider 17 along the first guide rail 15 by the roller 16.

[0033] The laparotomy and evisceration mechanism consists of a second connecting plate 25, a third base plate 26, an laparotomy knife 27, a first fixed support 28, a second cylinder 29, and a second fixed support 30. The second cylinder 29 is bolted to the frame by the first fixed support 28 and the second fixed support 30, and the second cylinder 29 is tilted at a 10-degree angle to the frame. The laparotomy knife 27 is driven by the second cylinder 29, and moves through the gap between the third base plate 26 to perform the laparotomy. The second connecting plate 25 and the third base plate 26 are connected by bolts. The evisceration organs fall into the waste collection box 4 below.

[0034] The pushing mechanism includes a baffle 21, a first cylinder 22, a hinge support 23, a second base plate 24, and a push block and a push rod 31. The second base plate 24 is fixedly connected to the frame by bolts. The first cylinder 22 is fixedly connected to the frame by bolts. The hinge support 23 fixes the two baffles 21 and the second base plate 24 to each other by bolts. The output end of the first cylinder 22 is fixedly connected to the push rod 31. The fish is pushed from the feeding port 2 to the designated position by the pushing mechanism.

[0035] The frame is a solid frame with a height of 40cm and a length of 120cm.

[0036] The servo motor has a rated speed of 300 r / min.

[0037] The thickness of the pressure plate and connecting plate is 5-10mm.

[0038] The blade spacing of the scraper can be varied from 2cm to 40cm by adjusting the spring with a nut.

[0039] The push rod is a slender rod with a diameter of 20mm and a length of 50cm. The push block and the push rod 31 are connected by bolts. The push block is a hollow cuboid. The push stroke of the push rod is 45cm.

[0040] In the clamping mechanism, the distance between the two pressure plates can be reduced to a size that can clamp the fish by adjusting the spring with a nut.

[0041] The laparotomy knife is a sharp blade. The gap between the two base plates is 5cm. The cylinder-driven blade has a stroke of 45cm.

[0042] Working principle:

[0043] This device is powered by a servo motor 7, a first cylinder 22, and a second cylinder 29. First, the fish to be processed is placed between the feeding port 2 and the baffle 21. Then, the first cylinder 22 is activated, pushing the fish into the clamping and descaling mechanism. The first cylinder then resets, the nut 18 rotates, extending the spring length, and the pressure plate 11 presses the fish tightly. Next, the servo motor 7 starts, driving the eccentric wheel 9 to rotate. The roller 16 fixed on the eccentric wheel 9 moves on the second guide rail 10, causing the scaling blade 13 fixed on the slider 17 to move back and forth on the first slide rail 15, thus achieving the descaling process. After descaling, the second cylinder 29 starts moving, causing the abdominal opening blade 27 to move forward to open the abdomen. After opening, the first cylinder 22 starts again, pushing out the processed fish and pushing in the next fish to be processed. This reciprocating motion continuously performs the fully automatic descaling and viscera cleaning of the fish.
