[0002] With consumers placing increasing emphasis on food safety and processing efficiency, the fish processing industry is facing unprecedented challenges. While existing automated fish-killing machines alleviate some of the manual labor burden, they still have many shortcomings in practical application. First, their poor sealing means that fishy odors inevitably spread into the surrounding environment during the killing process, creating a persistent unpleasant smell in the kitchen. Second, the equipment has limited capabilities in fish fixation and detection, making it difficult to precisely adjust according to the size, species, and other attributes of the fish. This results in less refined scaling and other processing steps, potentially even damaging the fish. Finally, the equipment's control system lacks sufficient intelligence, failing to provide real-time feedback and dynamic adjustments, leading to inconsistent processing results and often requiring manual intervention, thus reducing overall efficiency and automation levels. Summary of the Invention

[0038] The following combination Figures 1-4 This application provides an automated fish-killing machine, which includes a main frame 1, a pull-out fish drawer 2, a descaling device 3, a cleaning device 4, and a control device 5.

[0039] The fish drawer 2 is equipped with a fixing and detection device 6. The fixing and detection device 6 is used to fix the fish, automatically adjust the fixing position according to the size of the fish, and detect the fish's attribute parameters, which include at least the fish's species, posture, or size parameters.

[0040] The descaling device 3 is used to adjust the scaling structure 311 according to the fish's attribute parameters and to perform descaling operations on the fish.

[0041] The cleaning device 4 is used to rinse the scaled fish to remove residue.

[0042] Cleanliness testing unit 40 is used to test the cleanliness parameters of the fish surface, which characterize the removal of fish scales.

[0043] The control device 5 is electrically connected to the fixing and detection device 6, the descaling device 3, the cleaning device 4, and the cleaning detection mechanism 40. The control device 5 is used to control the descaling device 3 and the cleaning device 4 to perform descaling and cleaning operations according to the attribute parameters and cleanliness parameters, and to determine whether to perform a second descaling operation based on the cleanliness parameters of the fish surface after cleaning.

[0044] The automatic fish-killing machine operates as follows: Fish are placed in a pull-out fish drawer 2 within the main frame 1. The fish is secured by a fixing and detection device 6, which adjusts its position according to the fish's size to ensure stability. Simultaneously, the device detects and identifies the fish's species, posture, and size parameters. These parameters are transmitted to the control device 5. Upon receiving these parameters, the control device 5 adjusts the scaling structure 311 in the descaling device 3 to a suitable working state based on the fish's species, posture, and size. The descaling device 3 then performs the descaling operation, ensuring moderate scraping force without damaging the fish flesh. The fish is then thoroughly rinsed by a washing device 4 to remove residual scales and other impurities. After washing, the cleanliness parameters of the fish surface are detected and transmitted to the control device 5. The control device 5 determines whether secondary descaling is necessary based on these parameters. If the cleanliness parameter exceeds a preset threshold, the descaling device 3 performs a secondary descaling operation; otherwise, this step is skipped. After all operations are completed, the control device 5 sends a signal to the operator, prompting them to pull out the fish drawer 2 and take out the processed fish.

[0045] In this embodiment, the cleanliness threshold is a pre-set value for the fish surface cleanliness when the fish's scaling condition meets the standard. The higher the fish surface cleanliness parameter, the worse the current scaling condition of the fish.

[0046] This embodiment achieves a high degree of automation in the entire fish-killing process, reducing manual intervention and improving processing efficiency. The fixing and detection device can automatically adjust its fixing position according to the size of the fish, and the descaling device can also adjust the scaling structure according to the type and size of the fish to ensure consistent processing results. The control device can intelligently adjust the descaling device 3 and the cleaning device 4 based on real-time detected data, achieving precise control and improving processing efficiency and descaling quality.

[0047] Furthermore, the fixing and detection device 6 includes a fixing device 61 and a first detection mechanism. The fixing device 61 includes an elastic reset structure 611, which is used to connect to the tail of the fish. The elastic reset structure 611 is provided with a first detection mechanism for real-time detection of attribute parameters.

[0048] Specifically, the fixing device 61 also includes a fish head fixing structure 612, which is located inside the fish drawer 2 at the end away from the elastic reset structure 611, and is used to fix the fish head or gills. In one possible embodiment, the fish head fixing structure 612 is a set of adjustable clamping arms or a piercing fixing structure that can pierce the fish head or gills. In one possible embodiment, the elastic reset structure 611 is a spring-type reset structure, with one end of the spring connected to the inner wall of the fish drawer 2 and the other end used to connect to the fish tail, which can accommodate fish of different sizes. The first detection mechanism can be a pose sensor installed on the elastic reset structure 611, which can detect the size of the fish fixed inside the fish drawer 2. In one possible embodiment, the first detection mechanism can be an image recognition system combining a pose sensor and a camera, which can accurately identify the species, posture, and size of the fish. In this embodiment, when using the fish-killing machine, the fish drawer 2 needs to be opened first, and the fish is fixed in the fish drawer 2 by the fixing and detection device 61. Then the fish drawer 2 is closed before further scaling and cleaning steps are performed. The fish fixing steps are simple and ensure the fish are stably fixed during the processing.

[0049] Furthermore, the cleaning device 4 includes a spraying mechanism, which includes a connecting pipe 42 and multiple spray heads 41. The connecting pipe 42 is connected to the water inlet of the main frame 1.

[0050] Specifically, the spraying mechanism is located on one side of the main frame 1. The spraying mechanism includes multiple spray heads 41, which are connected to the water inlet of the main frame 1 via connecting pipes 42 to achieve uniform spraying of high-pressure water. In one possible embodiment, the spraying mechanism includes two spray heads 41, which are respectively located on the upper and lower sides of the fish catcher drawer 2 to simultaneously rinse both sides of the fish.

[0051] In one possible implementation, the cleaning detection mechanism 40 is a pressure sensor mounted on the descaling device 3, used to acquire cleanliness parameters of the fish surface. The pressure sensor adheres to the fish surface, and when scales are not completely removed, it detects minute pressure differences caused by protruding scales or uneven surfaces. If the pressure sensor outputs high pressure signals at multiple locations on the fish surface, it indicates that scale removal is incomplete and further processing is needed. If the electrical signal output by the pressure sensor is relatively uniform and below a set threshold, it indicates that the scales on the fish surface have been largely removed, achieving the expected cleanliness requirements. In another possible implementation, the cleaning detection mechanism 40 can also be configured as a device that uses a camera in conjunction with the pressure sensor to acquire fish surface cleanliness parameters. In this embodiment, the cleaning detection mechanism 40 can acquire fish surface cleanliness parameters to determine the descaling status of the fish.

[0052] Furthermore, the descaling device 3 includes a first descaling component 31, a second descaling component 32 and a corresponding descaling motor 33 respectively disposed on both sides of the fish body. The first descaling component 31 and the second descaling component 32 each include a plurality of scale scraping structures 311 disposed at intervals.

[0053] Specifically, the scaling structure 311 includes a rotating shaft and multiple scrapers evenly arranged circumferentially and axially on the rotating shaft. Each scaling structure 311 can be controlled to rotate by a descaling motor 33 to perform the scaling operation. The first descaling assembly 31 and the second descaling assembly 32 are respectively located on the upper and lower sides of the fish drawer 2 so that the scales on both sides of the fish can be removed after the fish is fixed. In one possible embodiment, the descaling motor 33 can be a variable frequency speed control motor. The descaling motor 33 is connected to the rotating shaft through a gear or belt drive system to realize the rotation of the scaling structure. The descaling motor 33 can adjust its speed according to the instructions of the control device 5 to adapt to the scaling needs of different fish.

[0054] Furthermore, the main frame 1 is equipped with a garbage drawer 11, which is located below the fish catch drawer 2 and is used to collect garbage and waste generated during the scaling process.

[0055] In this embodiment, the waste drawer 11 is located below the fish catch drawer 2, featuring a compact structure that facilitates the direct collection of waste and debris generated during the scaling process. The pull-out fish catch drawer 2 and waste drawer 11 create a more compact overall structure for the fish-killing machine, ensuring good sealing and facilitating the securing of fish and the removal of waste. This contributes to maintaining a clean and hygienic environment and makes it suitable for a wider range of applications.

[0056] In another possible implementation, a garbage box 12 is provided inside the main frame 1, located below the descaling device 3, for collecting garbage and waste generated during the descaling process. A water outlet 13 is located below the garbage box 12 for discharging liquids and wastewater generated during the use of the fish-killing machine.

[0057] Furthermore, the control device 5 includes a descaling control module, which controls the corresponding number and interval of scale-scraping structures 311 to descale the fish based on the attribute parameters detected by the first detection mechanism. In this embodiment, the control device 5 calculates the appropriate number of scale-scraping structures 311 and their activation intervals for the current fish species based on the fish attribute parameters detected by the first detection mechanism, according to a preset algorithm and rules. For example, for large fish, more scale-scraping structures 311 may need to work simultaneously with a smaller interval; while for small fish, the number of scale-scraping structures 311 may be reduced and the interval increased. The control device 5 sends a control signal to the descaling motor 33 to activate the corresponding number and interval of scale-scraping structures 311 for descaling. During the descaling process, the motor speed can be dynamically adjusted as needed to ensure optimal descaling effect.

[0058] This embodiment, by precisely controlling the number and spacing of the scaling structures, enables personalized descaling solutions for fish of different sizes, significantly improving descaling efficiency. It achieves rapid and accurate descaling without manual adjustment, reducing labor costs and intensity. The entire descaling process is highly automated, minimizing errors and uncertainties caused by human intervention and improving the stability and reliability of the production line.

[0059] Furthermore, the control device 5 includes a wireless communication module 51, which is used to communicate with a mobile device and / or a computer to remotely control the operation of the fish-killing machine.

[0060] Specifically, a wireless communication module 51, such as a Wi-Fi, Bluetooth, or 4G / 5G module, is integrated within the control device 5, enabling the fish-killing machine to establish a communication connection with external mobile devices or computers. Users can send control commands to the wireless communication module 51 via their mobile devices or computers. After parsing the commands, the module executes the corresponding operations through the control device 5, such as starting / stopping descaling and adjusting descaling parameters. Users can also view the real-time operating status of the fish-killing machine through a remote control APP or web interface on their mobile devices or computers, including the current number of fish being processed, descaling progress, and cleanliness. This embodiment allows users to remotely monitor and operate the fish-killing machine, improving its flexibility, convenience, and intelligence.

[0061] Furthermore, the control device 5 includes a time prediction module, which is used to obtain the estimated descaling completion time based on the attribute parameters and the preset target parameters after descaling.

[0062] Specifically, the time prediction module predicts the estimated scaling completion time based on the collected fish's attribute parameters, such as species, size, and weight, and preset target parameters after scaling, such as cleanliness standards, using a time prediction model. In one possible implementation, the scaling completion time can be displayed via a remote control app or a display device mounted on the outer wall of the main frame 1. This embodiment of the fish-killing machine allows users to know the estimated scaling completion time in advance by accurately predicting it, enabling them to better plan subsequent work and improve the overall user experience.

[0063] This application embodiment also provides a control method for an automated fish-killing machine, the method comprising:

[0064] The fish to be processed are placed in the fish catch drawer, and their heads and tails are fixed by a fixing and detection device;

[0065] Obtain the attribute parameters of the fish, which include at least the fish species, posture, or size information;

[0066] Based on the aforementioned attribute parameters, the corresponding number and interval of scaling structures are controlled to perform scale removal operations on the fish.

[0067] After scaling is completed, the cleaning device is activated to clean the fish;

[0068] Obtain the cleanliness parameters of the fish surface after cleaning;

[0069] If the cleanliness parameter is greater than the preset cleanliness threshold, then the secondary descaling operation is initiated.

[0070] Before the second descaling operation in this embodiment, the current descaling information of the fish can be obtained. The current descaling information is the surface cleanliness information of the fish. Based on the current descaling information of the fish, the working parameters of the descaling device are adjusted, such as the number of scale scraping structures, the interval distance, and the speed of the descaling motor. Based on the adjusted working parameters, the fish-killing machine is controlled to descale the fish again.

[0071] The control method of the fish-killing machine in this embodiment also includes: predicting the expected descaling completion time based on the fish's attribute parameters and the preset target parameters after descaling.

[0072] In one possible implementation, the control method for the automated fish-killing machine includes:

[0073] The fish to be processed are placed in the fish catch drawer, and their heads and tails are fixed by a fixing and detection device;

[0074] Obtain the attribute parameters of the fish, which include at least the fish species, posture, or size information;

[0075] Based on the fish's attribute parameters and the preset target parameters after descaling, the estimated descaling completion time is predicted and displayed through a display device and / or a remote control APP.

[0076] Based on the aforementioned attribute parameters, the corresponding number and interval of scaling structures are controlled to perform scale removal operations on the fish.

[0077] After the first scaling is completed, the cleaning device is activated to clean the fish;

[0078] Obtain the cleanliness parameters of the fish surface after cleaning;

[0079] If the cleanliness parameter is greater than the preset cleanliness threshold, a second descaling operation is initiated, and the descaling completion time is updated in real time.

[0080] This embodiment achieves a high degree of automation in the entire fish-killing process, reducing manual intervention and improving processing efficiency. The fixing and detection device can automatically adjust its fixing position according to the size of the fish, and the descaling device can also adjust its scaling structure according to the type and size of the fish to ensure consistent processing results.
