Description

Technical Field

[0001] This invention relates to the field of fish processing equipment technology, and in particular to a multifunctional fish processing machine and a fish processing method. Background Technology

[0002] my country is a major aquaculture and consumer of aquatic products. Scale, back opening, and viscera cleaning are the core steps in the initial processing of fish. Currently, fish processing equipment on the market generally suffers from single functionality and poor adaptability: most equipment only has independent scale or back opening functions, requiring multiple machines to complete the entire processing step by step. The processes are scattered and require multiple manual transfers, resulting in low overall processing efficiency and high labor costs.

[0003] Meanwhile, most existing descaling equipment can only process the scales on the sides of the fish, making it difficult to cover the back and belly of the fish. The scales are not fully covered and the residue rate is high. Moreover, the working gaps of the equipment are mostly fixed structures, which cannot adapt to different fish sizes. This can easily lead to problems such as incomplete scaling of small fish and damage to the flesh of large fish due to compression. The equipment's versatility and processing quality are difficult to meet production needs. Summary of the Invention

[0029] like Figures 1-7As shown in the figure, this embodiment of the invention provides a multifunctional fish processing machine.

[0030] A multi-functional fish processing machine includes a frame 1. The frame 1 is equipped with a conveying mechanism for conveying fish. Along the fish conveying direction, the frame 1 is sequentially arranged a fish-clamping assembly 3, a descaling roller assembly 4, a fish belly descaling assembly 5, a back-opening module 8, and an internal organ cleaning module 9. The conveying mechanism, the fish-clamping assembly 3, the descaling roller assembly 4, and the fish belly descaling assembly 5 are all elastically connected to the frame 1. The descaling roller assembly 4 includes two descaling rollers 42 and two descaling roller drive components 43. The descaling rollers 42 are rotatably mounted one-to-one in the vertical direction. On the frame 1, the descaling roller drive unit 43 is mounted one by one on the frame 1. The output end of the descaling roller drive unit 43 is connected to the descaling roller 42. A first gap is provided between the two descaling rollers 42. The fish belly descaling assembly 5 includes two descaling wheels 53 and two descaling drive units 54. The descaling wheels 53 are rotatably mounted on the frame 1 in the horizontal direction. The descaling drive units 54 are mounted one by one on the frame 1. The descaling drive units 54 are connected to the descaling wheels 53 in a transmission manner. A second gap is provided between the two descaling wheels 53.

[0031] This invention integrates five core processes—fish clamping and positioning, side descaling, belly and back descaling, back opening, and internal organ cleaning—into a single machine. These processes are sequentially connected along the fish conveying direction, allowing for complete processing with a single fish feed. This eliminates the need for manual handling involving multiple machines and process switching, effectively shortening the processing cycle and reducing labor costs. The machine employs a structure where vertical double descaling rollers 42 and horizontal double descaling wheels 53 work in tandem, enabling circumferential descaling of the fish's sides, back, and belly. This addresses the shortcomings of existing equipment that does not thoroughly descale the belly and back, improving descaling quality. Furthermore, the conveying mechanism, fish clamping assembly 3, descaling roller assembly 4, and belly descaling assembly 5 are all elastically connected to the frame 1, allowing for adaptive adjustment of the working gap according to fish size. This adapts to different fish species, avoiding rigid compression that could damage the fish meat, and ensuring the equipment's versatility.

[0032] The multifunctional fish processing machine described in this embodiment has an assembly plate 2 in the middle of the frame 1, which facilitates the connection and fixation of various components to the assembly plate 2.

[0033] This embodiment describes a multifunctional fish processing machine. The fish clamping assembly 3 includes a lower clamping plate 31 and an upper clamping plate 32 arranged opposite each other. The lower clamping plate 31 is fixed to the frame 1, and a first telescopic rod assembly 33 is provided between the upper clamping plate 32 and the frame 1. A first spring 34 is sleeved on the outer periphery of the first telescopic rod assembly 33. The two ends of the first spring 34 respectively abut against the upper end surfaces of the frame 1 and the upper clamping plate 32, allowing the upper clamping plate 32 to reciprocate vertically. Specifically, by cooperating with the vertically arranged first telescopic rod assembly 33 and the first spring 34, the fish clamping assembly 3 can adaptively adjust the clamping gap according to the thickness of the fish, forming a stable clamp for fish of different thicknesses, ensuring the correct feeding posture of the fish, and avoiding fish displacement that affects the subsequent descaling accuracy. It can be understood that the cross-section of both the lower clamping plate 31 and the upper clamping plate 32 is a V-shaped groove to facilitate the insertion of the fish.

[0034] The multifunctional fish processing machine described in this embodiment includes a descaling roller assembly 4 comprising two descaling roller supports 41; descaling rollers 42 are rotatably mounted on the descaling roller supports 41, and descaling roller drive components 43 are fixed to the top of the descaling roller supports 41; a second telescopic rod assembly 44 is provided between the descaling roller supports 41 and the frame 1, the second telescopic rod assembly 44 is arranged in a horizontal direction, and a second spring 45 is sleeved on the outer periphery of the second telescopic rod assembly 44, the two ends of the second spring 45 respectively abutting against the outer sides of the frame 1 and the descaling roller supports 41, so that the descaling roller supports 41 can reciprocate in a horizontal direction; the outer periphery of the descaling rollers 42 is provided with multiple layers of first serrations 46. Specifically, the descaling roller bracket 41 is connected to the frame 1 via the horizontally arranged second telescopic rod assembly 44 and the second spring 45, which can drive the descaling roller 42 to adapt to the horizontal displacement of the fish body width, so that the descaling roller 42 always fits the side of the fish body with a stable force; in conjunction with the first serration 46 structure on the outer periphery of the descaling roller 42, the thoroughness of descaling on the side can be effectively improved, and it can be adapted to fish species of different widths.

[0035] The multifunctional fish processing machine described in this embodiment includes a fish belly descaling assembly 5 comprising an upper frame 51 and a lower frame 52. Two descaling wheels 53 are rotatably mounted on the upper frame 51 and the lower frame 52, respectively. A third telescopic rod assembly 55 is provided on the top of the frame 1. The bottom of the third telescopic rod assembly 55 is connected to the top of the upper frame 51. A third spring 56 is sleeved on the outer periphery of the third telescopic rod assembly 55. The two ends of the third spring 56 abut against the top of the frame 1 and the upper frame 51, respectively, allowing the upper frame 51 to reciprocate in the vertical direction. The descaling wheels 53 are provided with a plurality of second serrations 57 on their outer periphery. Specifically, the upper frame 51 is connected to the frame 1 via a vertically arranged third telescopic rod assembly 55 and a third spring 56, which can drive the upper descaling wheel 53 to rise and fall adaptively with the height of the fish, ensuring that the upper and lower descaling wheels 53 fit tightly against the back and abdomen of the fish; in conjunction with the second serration 57 structure on the outer periphery of the descaling wheel 53, the descaling effect on the abdomen and back is enhanced, solving the problem of incomplete descaling of the abdomen and back in traditional equipment.

[0036] This embodiment describes a multi-functional fish processing machine. The conveying mechanism includes two first conveying components 6. First conveying components 6 are provided between the descaling roller assembly 4 and the fish belly descaling assembly 5, and between the fish belly descaling assembly 5 and the back-opening module 8. Each first conveying component 6 includes two upper conveying bases 61 and two lower conveying bases 62 arranged opposite each other. A rotating rod 63 is rotatably mounted between each of the upper and lower conveying bases 61 and 62. Multiple conveying wheels 64 are sleeved on the rotating rods 63. A conveying drive component 65 is provided on the top of each upper conveying base 61. The output end of the conveying drive component 65 is connected to the rotating rod 63. Multiple abutment blocks 610 are provided around the outer wall of each conveying wheel 64. Specifically, two sets of wheel-type first conveying components 6 are set between descaling process nodes. The fish is smoothly conveyed by the clamping action of the two conveying wheels 64, ensuring smooth transition of the fish between each descaling module, stable conveying posture, avoiding fish movement deviation, and ensuring the processing position accuracy of each process.

[0037] Understandably, for the descaling roller assembly 4 and the two first conveying assemblies 6, in order to control the vertical position of the fish, the descaling roller assembly 4 uses multiple layers of first serrations 46 arranged in a ring, with gaps between each layer of first serrations 46. During descaling, the outer walls of the first serrations 46 located at the upper and lower ends of the fish abut against the fish, making it difficult for the fish to rise or fall during descaling. Similarly, for the first conveying assemblies 6, the abutting block 610 outside the conveying wheel 64 abuts against the fish during conveying, making it difficult for the fish to rise or fall during descaling. This facilitates vertical control of the fish and makes it easier to open the back and clean the internal organs later.

[0038] Understandably, a positioning groove 58 is provided in the middle of the two descaling wheels 53. The cross-section of the positioning groove 58 is trapezoidal, and the side closest to the shaft of the descaling wheel is the narrow side of the trapezoid. The second serration 53 is provided on both sides of the positioning groove 58. With the above configuration, the fish body can be better positioned when it is in the fish belly descaling component 5, the fish body will not sway from side to side, the belly descaling effect is better, and it is also convenient to send it into the next first conveying component 6.

[0039] This embodiment of a multi-functional fish processing machine includes a fourth telescopic rod assembly 66 and a fifth telescopic rod assembly 67 horizontally positioned between the lower conveyor base 62, the upper conveyor base 61, and the frame 1. A fourth spring 68 is fitted around the outer periphery of the fourth telescopic rod assembly 66, with both ends abutting against the outer sides of the frame 1 and the lower conveyor base 62. A fifth spring 69 is fitted around the outer periphery of the fifth telescopic rod assembly 67, with both ends abutting against the outer sides of the frame 1 and the upper conveyor base 61. Specifically, the upper and lower conveyor bases achieve self-adaptive horizontal adjustment through the fourth telescopic rod assembly 66 and the fifth telescopic rod assembly 67 in conjunction with the springs. This allows the spacing between the conveyor wheels 64 to automatically adjust according to the width of the fish, maintaining a suitable clamping force. This avoids both excessive clamping that could damage the fish meat and excessive clamping that could cause the fish to slip and shift.

[0040] This embodiment describes a multi-functional fish processing machine. The conveying mechanism includes a second conveying component 7, which comprises two driving wheels 71, two driven wheels 72, and two conveyor belts 73. The conveyor belts 73 are wound around the driving wheels 71 and the driven wheels 72. The driving wheels 71 are rotatably mounted on the frame 1. A belt drive mechanism 77 is provided on the mounting plate 2. The output end of the belt drive mechanism 77 is connected to the driving wheels 71. A base 74 is provided at the bottom of the driven wheels 72. A sixth telescopic rod assembly 75 is provided horizontally between the base 74 and the frame 1. A sixth spring 76 is sleeved on the sixth telescopic rod assembly 75. The two ends of the sixth spring 76 abut against the outer sides of the frame 1 and the base 74, respectively, so that the driven wheels 72 can reciprocate horizontally to adjust the position of the conveyor belts 73. The back-opening module 8 and the internal organ cleaning module 9 are both disposed between the two conveyor belts 73. Specifically, multiple driven wheels 72 are provided. In this embodiment, each conveyor belt 73 is connected to three driven wheels 72. The belt-type second conveyor assembly 7 carries the back opening and internal organ cleaning process. The flexible conveyor belt 73 can reduce the squeezing damage to the fish body and can stably clamp from both sides of the fish body, which is very beneficial to the back opening action. The driven wheels 72 can achieve horizontal adaptive adjustment through the sixth telescopic rod assembly 75 and the sixth spring 76, which can synchronously adjust the belt spacing to adapt to fish of different sizes while ensuring the stability of the conveying.

[0041] This embodiment describes a multi-functional fish processing machine. The back-opening module 8 includes a back-opening support plate 81, a back-opening drive mechanism 82, and a back-opening cutter 83. The back-opening support plate 81 is connected to the frame 1. The back-opening drive mechanism 82 is mounted on the back-opening support plate 81, and its output end is connected to the back-opening cutter 83. Specifically, the back-opening module 8 adopts an independent support plate structure for mounting the drive mechanism and the cutter. The overall structure is stable, and the installation and positioning are precise, ensuring the positional accuracy and operational stability of the back-opening cutter 83 during operation, resulting in neat and consistent fish back cuts.

[0042] This embodiment describes a multi-functional fish processing machine. The viscera cleaning module 9 includes a viscera cleaning support plate 91, a cleaning drive mechanism 92, and a cleaning brush 93. The viscera cleaning support plate 91 is connected to the frame 1. The cleaning drive mechanism 92 is mounted on the viscera cleaning support plate 91, and its output end is connected to the cleaning brush 93. Specifically, the viscera cleaning module 9 adopts a brush-type cleaning structure. The drive mechanism drives the cleaning brush 93 to rotate, which can efficiently and thoroughly remove the fish's internal organs without damaging the fish's internal tissues and flesh, ensuring the integrity of the processed fish.

[0043] The multifunctional fish processing machine described in this embodiment includes two descaling roller assemblies 4, which are arranged sequentially along the fish conveying direction. Specifically, the two sets of descaling roller assemblies 4 arranged sequentially along the conveying direction can perform continuous secondary descaling on the side of the fish, further reducing the scale residue rate, improving the processing quality of side descaling, and making it suitable for fish species with thicker scales and stronger adhesion.

[0044] This embodiment also provides a fish processing method based on a multi-functional fish processing machine. The fish processing method includes the following steps: S1. Place the fish to be processed at the feeding end of the equipment, clamp the fish with the fish clamping component 3, and then convey the fish backward along the conveying direction through the conveying mechanism. S2. The fish body enters the first gap between the two descaling rollers 42. The two descaling roller drive units 43 drive the corresponding descaling rollers 42 to rotate, and scrape off the fish scales on both sides of the fish body. S3. The fish body is conveyed by the conveying mechanism to the second gap between the two descaling wheels 42. The two descaling drive components drive the corresponding descaling wheels to rotate, scraping off the scales on the back and belly of the fish body. S4. The scaled fish is conveyed to the back-opening module by the conveying mechanism. The back-opening drive mechanism drives the back-opening blade to cut open the back of the fish. S5. After the fish is opened, it continues to be transported to the internal organ cleaning module via the conveying mechanism. The cleaning drive mechanism drives the cleaning brush to remove the internal organs of the fish. After processing, the finished product is output.

[0045] The specific working principle and steps are as follows: S1. Place the fish body into the V-shaped groove between the lower clamping plate 31 and the upper clamping plate 32 of the fish clamping assembly 3. The thickness of the fish body pushes the upper clamping plate 32 to rise along the first telescopic rod assembly 33. The first spring 34 is compressed and generates a reverse elastic force, pushing the upper clamping plate 32 down to clamp the fish body, so that the fish body maintains an upright conveying posture and enters the subsequent process. It can automatically adapt to fish bodies of different thicknesses.

[0046] S2. The fish body, influenced by the rotational force of the descaling roller assembly 4, enters the first gap between the two sets of descaling roller assemblies 4. The width of the fish body pushes the descaling rollers 42 to both sides, causing the descaling roller support 41 to move outward along the second telescopic rod assembly 44. The second spring 45 is compressed and provides a reverse thrust, so that the first serrations 46 of the two descaling rollers 42 on both sides fit tightly against the side of the fish body. The descaling roller drive 43 drives the descaling rollers 42 to rotate at high speed, scraping off the fish scales on both sides of the fish body through the first serrations 46. The two sets of descaling roller assemblies 4 work in sequence to achieve secondary scaling, further reducing the fish scale residue rate. During the process, the spacing of the descaling rollers 42 can be adaptively adjusted according to the width of the fish body to adapt to different sizes of fish species.

[0047] S3. After the side scaling is completed, the fish body is transported to the second gap of the fish belly scaling component 5 via the second group of first conveying components 6. The fish body pushes the upper scaling wheel 53 upward, causing the upper frame 51 to rise along the third telescopic rod component 55. The third spring 56 is compressed and provides a reverse elastic force, pushing the second serrations 57 of the upper and lower scaling wheels 53 to fit against the back and belly of the fish body respectively. The scaling drive component 54 drives the scaling wheel 53 to rotate, and the scales on the back and belly of the fish body are scraped off by the second serrations 57, which, together with the side scaling, achieves all-round scaling of the fish body.

[0048] S4. The scaled fish carcass enters the second conveyor assembly 7 through the first conveyor assembly 6, where it is flexibly held and conveyed forward by the conveyor belts 73 on both sides. The sixth spring 76 pushes the driven wheel 72 to adaptively adjust the distance between the two conveyor belts 73, ensuring stable holding of fish carcasses of different sizes while avoiding rigid compression that could damage the fish meat. When the fish carcass passes under the back-opening module 8, the back-opening drive mechanism 82 drives the back-opening cutter 83 to rotate, cutting the fish carcass along the center line of the back.
