Description

Technical Field

[0001] This invention relates to the technical field of fish processing, specifically to a processing method and apparatus for continuous descaling, gutting, and eviscerating of fish. Background Technology

[0002] In the initial processing of aquatic products, fish usually need to undergo a series of steps, including scaling, gutting, removing internal organs, and cleaning. These steps are important processing steps before the fish enters the subsequent deep processing or sales.

[0003] Currently, in most aquatic product processing facilities, the above-mentioned processing is still mainly done manually, which is not only labor-intensive and inefficient, but also makes it difficult to effectively guarantee the accuracy of gutting, processing consistency and hygiene conditions.

[0004] To improve processing efficiency, mechanized equipment for fish processing has emerged in existing technologies. However, most existing fish processing equipment is single-function, capable of performing only single steps such as scaling or gutting, and cannot achieve integrated continuous processing. This step-by-step processing method not only requires multiple machines, occupying a large production space, but also necessitates manual transfer of fish between steps, increasing labor intensity and processing time, and reducing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for continuously descaling, gutting and removing internal organs from fish, so as to overcome the above-mentioned defects in the prior art.

[0006] A processing device for continuous descaling, gutting and eviscerating of fish includes a frame, a descaling mechanism and a gutting and cleaning mechanism. Two connecting plates are symmetrically arranged on both sides of the frame, and one end of the two connecting plates is provided with the same receiving plate. An initial positioning component is provided on the frame above the receiving plate. The descaling knife and elastic scraper on the descaling mechanism scale the fish being transported under the drive of the conveying assembly. The gutting and cleaning mechanism uses a gutting knife and a peeling brush to gut and remove the internal organs from the fish under the drive of the conveying assembly.

[0007] Preferably, the initial positioning component includes a cylinder and a pressure plate, wherein the cylinder body of the cylinder is mounted on the frame, and the pressure plate is located at the lower end of the piston rod of the cylinder.

[0008] Preferably, the conveying assembly includes conveying rollers and a motor. The conveying rollers are arranged in two rows and rotatably connected to the frame. The two conveying rollers in each row are directly opposite each other. Each conveying roller has a synchronous pulley at its upper end and several conveying soft teeth along its circumference. The synchronous pulleys in the same row are connected by a synchronous belt. There are two motors and they are mounted on the frame. The output shaft of each motor is connected to one of the synchronous pulleys in the same row.

[0009] Preferably, the descaling mechanism further includes a second cylinder, and the descaling knife is provided with two blades and rotatably connected to the frame, and the upper end of the blade is provided with a second synchronous pulley connected to the first synchronous belt. The surface of the descaling knife is provided with scraping teeth that are spirally distributed along the axial direction. The second cylinder is provided on the frame and has two layers, each layer having two opposing second cylinders. The piston rod end of each second cylinder is provided with an elastic scraper.

[0010] Preferably, the guillotine cleaning mechanism further includes a second motor, a third cylinder, and a nozzle. The guillotine blade is rotatably connected to the frame and located below the elastic scraper. A third synchronous pulley is installed at the end of the guillotine blade. The second motor is mounted on the frame and its output shaft is connected to the third synchronous pulley. The stripping brush is rotatably connected to the frame and its end is provided with a fourth synchronous pulley. The third synchronous pulley and the fourth synchronous pulley are connected by a second synchronous belt. The third cylinder is mounted above the stripping brush and its piston rod has an arc-shaped abutment at its lower end. The nozzle is located on the frame on one side of the stripping brush and is connected to a water pump through a pipe.

[0011] Preferably, each elastic scraper is inclinedly disposed at the end of the piston rod of cylinder two.

[0012] Preferably, the receiving plate is provided with a trapezoidal groove.

[0013] Preferably, a collection trough is provided on the lower side of the frame, and a guide hopper is provided at the outlet at the bottom of the collection trough.

[0014] A method for continuously descaling, gutting, and removing internal organs from fish, using the aforementioned processing apparatus for continuously descaling, gutting, and removing internal organs from fish, includes the following steps: S1. Place the fish to be processed in the receiving plate with the belly facing down, and drive the pressure plate down through the piston rod of cylinder one to initially position and fix the fish. S2. Then start motor one and control the piston rod of cylinder one to retract, which will cause the pressure plate to loosen the fish body. The synchronous belt one will drive the descaling knife to rotate, and the scraping teeth on it will scrape the scales on both sides of the fish body. S3. Simultaneously, the conveyor roller is driven to rotate by the synchronous belt, and the soft teeth of the conveyor flexibly clamp the fish and convey it forward; at the same time, the piston rod of the cylinder drives the elastic scraper to fit the surface of the fish and perform secondary scaling on the fish. S4. After scaling, the fish continues to be transported to the gutting and cleaning mechanism. The piston rod on cylinder three drives the arc-shaped plate to press down on the fish. At the same time, the gutting knife rotates under the drive of motor two to cut the belly of the fish. After gutting, the fish passes through the peeling brush, which rotates under the drive of synchronous belt two and peels the internal organs out of the fish. At the same time, the nozzle sprays high-pressure water to rinse the inside of the fish cavity. S5. After processing, the processed fish is output from the device outlet and can proceed to subsequent processes.

[0015] The beneficial effects achieved by this invention are as follows: 1. This application achieves integrated continuous processing of fish by setting up a descaling mechanism and a gutting and cleaning mechanism. The fish can complete all processing steps in one transport process, without the need for manual transfer and multiple clamping, which greatly improves processing efficiency and reduces labor intensity.

[0016] 2. The conveying assembly of this application uses a conveying roller with soft conveying teeth, which can flexibly hold the fish body, ensuring conveying stability while avoiding damage to the fish surface. It is suitable for processing fish of different sizes. The descaling mechanism uses a rotating descaling knife in conjunction with an elastic scraper. The spirally distributed scraping teeth on the surface of the descaling knife can effectively remove fish scales. The elastic scraper, driven by a cylinder, assists in scraping the fish surface. The two-layer scraping structure ensures cleaner descaling. At the same time, the tilt setting and elastic design of the elastic scraper can adapt to fish of different sizes. The gutting knife rotates under the drive of a motor, which can accurately cut the belly of the fish. The peeling brush, in conjunction with the arc-shaped baffle and the spray nozzle, can clean the internal organs of the fish. Attached Figure Description

Detailed Implementation To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1-6 As shown, the present invention provides a processing device for continuous descaling, gutting and eviscerating of fish, including a frame 1, a descaling mechanism 6 and a gutting and cleaning mechanism 7. The frame 1 serves as the supporting structure of the entire device. A collection trough 11 is provided on the lower side of the frame 1. A guide hopper 12 is provided at the outlet of the bottom of the collection trough 11. The collection trough 11 is used to collect waste such as fish scales and evisceration generated during the processing. The guide hopper 12 facilitates the centralized discharge and treatment of waste. Two connecting plates 2 are symmetrically arranged on both sides inside the frame 1, and one end of the two connecting plates 2 is provided with the same receiving plate 3. The receiving plate 3 is used to place the fish to be processed. The receiving plate 3 is provided with a trapezoidal groove 31. The design of the trapezoidal groove 31 facilitates the positioning and placement of the fish, so that the fish can be easily placed into the groove when the belly is facing down. The frame 1 is provided with a preliminary positioning component 4 above the receiving plate 3. The preliminary positioning component 4 includes a cylinder 41 and a pressure plate 42. The cylinder body of the cylinder 41 is installed on the frame 1, and the pressure plate 42 is located at the lower end of the piston rod of the cylinder 41. When the fish is placed on the receiving plate 3, the cylinder 41 drives the pressure plate 42 to press down, so as to perform preliminary positioning and fixation of the fish. The conveying assembly 5 includes conveying rollers 51 and motors 52. Two rows of conveying rollers 51 are rotatably connected to the frame 1. Two conveying rollers 51 in each row face each other, forming a clamping and conveying channel for the fish. Each conveying roller 51 has a synchronous pulley 53 at its upper end and several soft conveying teeth 511 along its circumference. Synchronous pulleys 53 in the same row are connected by a synchronous belt 54. Two motors 52 are mounted on the frame 1, and the output shaft of each motor 52 is connected to one of the synchronous pulleys 53 in the same row.

[0025] The soft conveyor teeth 511 have appropriate elasticity, which can avoid damaging the surface of the fish while clamping the fish. The two rows of conveyor rollers 51 are arranged opposite each other to ensure the stability and straightness of the fish during the conveying process, so that the fish can be accurately conveyed to the gutting and cleaning mechanism 7. The descaling mechanism 6 also includes a second cylinder 64. Two descaling blades 61 are provided and rotatably connected to the frame 1, and their upper ends are provided with a second synchronous pulley 62 connected to the first synchronous belt 54. The surface of the descaling blades 61 is provided with scraping teeth 611 that are spirally distributed along the axial direction. The second cylinder 64 is provided on the frame 1 and is provided in two layers. Each layer has two opposing second cylinders 64. The piston rod end of each second cylinder 64 is provided with an elastic scraper 63.

[0026] The descaling knife 61 rotates under the drive of the synchronous belt 54. Its spirally distributed scraping teeth 611 effectively remove scales from both sides of the fish during rotation and provide axial guidance, thus simultaneously propelling the fish forward along the processing direction during descaling. The elastic scraper 63, driven by the cylinder 64, assists in scraping the fish surface. Each elastic scraper 63 is inclined at the end of the piston rod of the cylinder 64, allowing for a better contact angle between the scraper 63 and the fish surface, improving the scraping effect. The elastic scraper 63 has appropriate elasticity to adapt to fish of different sizes, and the two layers of elastic scrapers 63 ensure that the fish surface receives thorough scraping.

[0027] The guillotine cleaning mechanism 7 also includes a second motor 74, a third cylinder 77, and a nozzle 79. A guillotine cutter 71 is rotatably connected to the frame 1 and located below the elastic scraper 63. A synchronous pulley 73 is mounted at the end of the guillotine cutter 71. The second motor 74 is mounted on the frame 1, and its output shaft is connected to the synchronous pulley 73. A stripping brush 72 is rotatably connected to the frame 1, and its end is equipped with a fourth synchronous pulley 75. The third synchronous pulley 73 and the fourth synchronous pulley 75 are connected by a second synchronous belt 76. The third cylinder 77 is mounted above the stripping brush 72, and its piston rod has an arc-shaped abutment 78 at its lower end. The nozzle 79 is located on the frame 1 on one side of the stripping brush 72 and is connected to a water pump via a pipe.

[0028] Driven by motor 74, the gutting knife 71 rotates to precisely cut the fish's abdomen. The gutting knife 71 is a round blade with a sharp and durable edge, capable of quickly and accurately cutting open the fish's abdomen. The arc-shaped abutment 78 moves downward under the drive of cylinder 77, applying appropriate pressure to the fish's abdomen. The peeling brush 72 rotates under the drive of synchronous belt 76 to peel and clean the fish's internal organs.

[0029] The nozzle 79 is mounted on the frame 1 on one side of the peeling brush 72 and is connected to the water pump through a pipe. During the process of peeling the internal organs, the nozzle 79 sprays water into the fish body to rinse the peeled internal organs and residual impurities, and at the same time flushes the peeled internal organs into the collection tank 11.

[0030] Detailed implementation methods and principles: First, the fish to be processed is placed in the trapezoidal groove 31 of the receiving plate 3, with the belly facing down. Then, cylinder 41 is started, and the piston rod of cylinder 41 drives the pressure plate 42 to press down, initially positioning and fixing the fish. Then, motor 52 is started, and the piston rod of cylinder 41 is controlled to retract, causing the pressure plate 42 to release the fish. The synchronous belt 54 drives the descaling knife 61 to rotate, and during the rotation, it guides and pushes the fish along the conveying direction. The scraping teeth 611 on its surface scrape the scales on both sides of the fish. Simultaneously, the synchronous belt 54 drives the conveyor roller 51 to rotate, and the soft conveyor teeth 511 flexibly clamp the fish body and convey it forward; at the same time, the piston rod of the cylinder 64 drives the elastic scraper 63 to adhere to the surface of the fish body and perform secondary scaling to remove residual fish scales. The scraped fish scales fall into the collection tank 11 below.

[0031] After being scaled, the fish continues to be transported to the gutting and cleaning mechanism 7. The piston rod on cylinder 3 77 drives the arc-shaped abutment 78 to press down on the fish, while the gutting knife 71 rotates under the drive of motor 2 74 to cut open the fish's abdomen. After gutting, the fish passes through the peeling brush 72, which rotates under the drive of synchronous belt 2 76 and peels the fish's internal organs out of the fish. At the same time, the nozzle 79 sprays high-pressure water to rinse the inside of the fish cavity, ensuring that the internal organs are thoroughly cleaned. The peeled internal organs and rinsing water fall into the collection tank 11.

[0032] After processing, the processed fish is output from the device outlet and can be used for subsequent processes. The waste in the collection tank 11 is discharged through the guide hopper 12 and can be used for further processing.
