Description

Technical Field

[0001] This invention relates to the field of poultry cutting and processing technology, specifically to a poultry cutting device and cutting method. Background Technology

[0002] Currently, the poultry product processing industry is developing rapidly. Whether it's chicken nuggets from fast-food chains or diced chicken and duck pieces in home-cooked meals, market demand is increasingly strong. These products place extremely high demands on the uniformity of the size, shape, and weight of the raw meat pieces. To meet this demand for large-scale, standardized production, automated cutting equipment has emerged and has become an indispensable core piece of equipment in this field.

[0003] Regarding the aforementioned issues, existing poultry cutting equipment typically employs an assembly line operation mode. Its basic workflow generally involves feeding large, pre-processed pieces of poultry meat (such as boneless chicken breast) into the equipment, where they are cut by one or more sets of high-speed rotating blades. The cut pieces fall onto a conveyor belt below and are transported to the discharge port for collection. In some cases where the final product shape is critical, subsequent sorting or shaping processes are often required after discharge.

[0004] However, in actual operation, these traditional block cutting devices have some inherent defects that urgently need to be addressed.

[0005] A very obvious phenomenon is that after the initial cutting, the meat chunks often pile up haphazardly on the conveyor belt, completely lacking any order. This disorderly accumulation directly leads to uneven material layers, making it impossible for the blades to process the material evenly and effectively when it enters the next cutting station. The final cut products naturally vary in size and shape, resulting in a less than ideal product qualification rate.

[0006] To compensate for this deficiency, factories commonly add an extra manual sorting and arrangement process at the output end of the cutting equipment. This patchwork approach not only significantly increases valuable labor costs but also severely slows down the entire production line, creating an efficiency bottleneck. More importantly, the repeated manual contact also brings the risk of secondary contamination, which is something that must be avoided in the food processing industry.

[0007] Another headache is cleaning the equipment. The internal structure of many existing machines, especially components used for separation or guidance, is often directly welded to the frame, forming a fixed unit. This inevitably creates numerous structural gaps and unsanitary corners. In the daily production process, meat scraps and grease, once they get into these nooks and crannies, are extremely difficult to thoroughly clean with water guns or brushes. Over time, these areas become breeding grounds for bacteria, posing a significant threat to the food safety of the final product. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a poultry cutting device and cutting method, aiming to solve the problems of inconsistent finished product sizes caused by disorderly accumulation of materials after cutting in existing poultry cutting equipment, as well as the resulting inefficiency and high hygiene risks due to the need for secondary manual sorting.

[0014] Preferably, the second adjustment component includes a second adjustment plate, the bottom end of the flat brush is rotatably connected to the inside of the second adjustment plate, both sides of the second adjustment plate are provided with limiting side plates, and multiple slots are provided between the two. The second adjustment plate is slidably connected to the inside of the work box, and a second pin is inserted between the two limiting side plates and the second adjustment plate.

[0015] Preferably, the buffer assembly includes a first rotating shaft and a second rotating shaft, both of which are rotatably connected inside the load-bearing plate. An installation groove is provided on the opposite side between two adjacent partitions. The first rotating shaft and the second rotating shaft are slidably connected inside the installation groove. An adjustment groove is provided at the bottom front end of the installation groove, and a return spring is provided inside the adjustment groove.

[0016] Preferably, the rotating shaft is slidably connected inside the adjustment groove, and the top end of the return spring abuts against the outside of the rotating shaft, while the bottom end of the return spring is fixedly connected to the bottom of the adjustment groove.

[0017] Preferably, the load-bearing plate is rotatably connected between the two partitions.

[0018] A method for cutting poultry into pieces includes the following steps:

[0019] S1. Preparation Stage: Pre-adjustments are made based on the characteristics of the poultry meat pieces to be processed and the final product specifications. Operators sequentially insert and fix the bottoms of multiple partitions into the mounting bases on both sides of the sorting conveyor belt, thus forming multiple independent conveying channels on the conveyor belt. Subsequently, based on the average thickness of the meat pieces, the vertical height of the leveling brush in the dynamic leveling mechanism is set by adjusting the positions of pins one and two on adjustment components one and two within their corresponding slots.

[0020] S2. Preliminary Cutting: Start the device and feed large pieces of poultry meat into the feed inlet at the top of the working box. The meat first enters the drive assembly located on the left. The drive motor starts, driving a transmission gear to rotate through its output end. Since the two transmission gears mesh with each other, they drive two cutters to rotate in opposite directions, performing preliminary cutting on the meat pieces and processing them into strips.

[0021] S3. Lifting and Transfer: The initially cut strips of meat fall onto a feeding conveyor belt that is inclined to the upper right under the influence of gravity. The feeding conveyor belt runs, steadily lifting and transferring the strips of meat to its highest point on the upper right.

[0022] S4. Sorting, Buffering, and Draining: Strip-shaped meat pieces fall from the highest point of the feeding conveyor belt into the sorting conveyor belt, where they enter a channel defined by partitions and land on two symmetrically arranged load-bearing plates within the channel. When the meat pieces fall and contact the load-bearing plates, their impact force is transmitted to the buffer assembly through shaft one and shaft two. The load-bearing plates rotate or sink slightly, causing shaft one to compress the return spring inside the adjustment groove, effectively absorbing the impact energy and preventing damage to the meat pieces. After the impact, the rebound force of the return spring restores the load-bearing plates to their initial horizontal position. Simultaneously, during the process of the meat pieces remaining on and being conveyed on the load-bearing plates, the blood and water they carry drips through multiple draining grooves on the load-bearing plates, achieving initial drainage.

[0023] S5. Dynamic Leveling: The load-bearing plate carrying the strips of meat continues to move forward with the sorting conveyor belt, reaching below the dynamic leveling mechanism. At this time, the drive motor drives the leveling brush to rotate. The bristles of the leveling brush contact the surface of the meat on the load-bearing plate, gently sweeping and leveling it, pushing excessively piled meat to empty spaces, making the thickness of the meat layer on the load-bearing plate in each channel tend to be uniform.

[0024] S6. Secondary Fine Cutting: The flattened and arranged strips of meat are conveyed to the end of the sorting conveyor belt and enter the working range of another drive component located below it. This drive component works in the same way as in step S2, laterally cutting the neatly arranged strips of meat to precisely cut them into finished blocks of a set length.

[0025] S7. Finished Product Discharge: The final cut poultry meat pieces fall from the end of the sorting conveyor belt onto the discharge conveyor belt directly below. The discharge conveyor belt transports the processed finished meat pieces out of the work box for collection or to the next packaging process.

[0026] This invention provides a poultry cutting device and a cutting method. It has the following beneficial effects:

[0027] 1. In this invention, the pluggable connection between the partitions and the mounting base allows operators to easily remove all partitions used to separate passageways by hand after production, enabling independent, thorough cleaning and disinfection. In contrast, existing technologies often use welding or bolting for similar structures, creating numerous hard-to-reach hygiene dead zones that lead to the long-term accumulation of meat scraps and grease, fostering bacterial growth. This invention fundamentally solves this persistent problem, significantly improving equipment cleanliness, ensuring food safety, and also significantly reducing the intensity and time cost of cleaning work.

[0028] 2. This invention employs a double-layer stepped load-bearing plate structure, significantly enhancing the processing capacity of the material shaping area. When meat strips fall from a height, they preferentially fill the upper load-bearing plate. Once the upper plate is full, excess meat strips overflow naturally due to gravity and are caught by the lower load-bearing plate. Furthermore, the buffer component effectively eliminates the impact force of falling meat, achieving three-dimensional, self-adaptive material filling. In contrast, the commonly used flat single-layer conveyor belts in existing technologies often result in disorderly material accumulation, wasting significant effective carrying space and creating considerable difficulties for subsequent leveling. This invention, through a simple structural change, doubles the carrying capacity per unit area and the initial uniform distribution of materials, resulting in higher efficiency.

[0029] 3. This invention incorporates a dynamically leveling mechanism with adjustable height. The core of this mechanism is a rotating leveling brush that actively "combs" and "guides" excessively piled meat strips from the load-bearing plate into open spaces, rather than passively blocking them. Existing technologies either lack this leveling step, resulting in inconsistent finished product sizes, or use fixed scrapers, which are rigid and unsuitable for materials of different sizes. The dynamic leveling mechanism of this invention not only acts gently and protects the meat, but its height-adjustable design also gives the equipment great flexibility, perfectly adapting to the processing of different batches and types of poultry meat, thus ensuring a high degree of consistency in the size and weight of the final product.

[0030] 4. This invention provides a complete automated solution from "shaping and arranging" to "synchronous precision cutting." From the moment the material enters the sorting conveyor belt, it remains within an independent channel defined by partitions, arranged in an orderly manner throughout the process, until finally cut into pieces by a synchronized cutting blade assembly. This completely overturns the outdated model in existing technologies where, after the cutting machine outputs the meat pieces, they pile up haphazardly, requiring extensive manual secondary sorting and arranging. The solution of this invention directly eliminates the high-labor-cost, low-efficiency "secondary sorting" process, realizing automated assembly line operations from raw materials to well-ordered finished products. This not only greatly improves overall production efficiency but also avoids the risk of secondary contamination from manual handling and contact. Attached Figure Description

Detailed Implementation

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see the appendix Figure 1 - Appendix Figure 8This invention provides a poultry dicing device. The main structure of the device is integrated into a robust and durable working box 1. The working box 1 is made of stainless steel with a brushed or mirror-finished surface, which not only ensures the hygiene standards of the food processing environment but also facilitates daily cleaning and maintenance. Multiple feet 11 are evenly arranged at the bottom of the working box 1 to ensure stable operation of the equipment under different ground conditions and reduce vibration caused by unevenness.

[0043] Inside the work chamber 1, the entire processing flow follows a material movement trajectory from left to right and from top to bottom, with each functional unit compactly arranged and seamlessly connected. At the upper left of the device, there is a feed hopper (not shown), below which is the first drive assembly 4, which performs the initial cutting task. Immediately following is a feeding conveyor belt 3, angled upwards to the right, used to lift the initially cut meat pieces. The end point of the feeding conveyor belt 3 is directly above the starting end of the sorting conveyor belt 7. Above the conveying path of the sorting conveyor belt 7, a dynamic leveling mechanism 5 is installed. When the material reaches the end of the sorting conveyor belt 7, another drive assembly 4 is located below it for final precision cutting, while the finished product falls directly into the discharge conveyor belt 2 at the bottom of the device, which is responsible for transporting the finished product to an external collection container or the next process step.

[0044] There are two sets of drive components 4, with identical structure and function, responsible for initial cutting and fine cutting respectively. A thickened pad 401 is fixedly connected to the side wall of the work box 1 by high-strength bolts, providing a stable mounting base for the drive motor 402. The output shaft of the drive motor 402 transmits its power to one of the transmission gears 403 via a coupling. This transmission gear 403 meshes precisely with another transmission gear 403 of the same specification. The central hole of each transmission gear 403 is coaxially fixed to the blade shaft of a cutter 404. The cutter 404 is preferably a disc-shaped grid blade made of high-hardness alloy steel, with multiple parallel sharp blades. When the drive motor 402 starts, its rotational motion is converted into synchronous, opposite rotational motion of the two cutters 404 through the meshing of the pair of transmission gears 403. This quickly and cleanly cuts the poultry meat pieces passing between them into uniform strips or blocks, resulting in high cutting efficiency and neat finished products.

[0045] After initial cutting, the strips of meat fall onto the surface of the feeding conveyor belt 3 under the influence of gravity. This feeding conveyor belt 3 features an integral baffle, and its tilt angle is precisely calculated to ensure that the meat strips will neither slip due to gravity nor be thrown out by centrifugal force during lifting. Its highest point on the upper right side, the discharge end, extends precisely above the sorting conveyor belt 7, ensuring a smooth transition of materials to the next workstation.

[0046] On both sides of the outer side of the sorting conveyor belt 7 frame, multiple reinforced mounting bases 702 are fixedly welded at equal intervals along the conveying direction. Each mounting base 702 has a vertical slot for inserting a partition 701. The bottom of the partition 701 is designed with a tenon and mortise structure that matches the slot, allowing operators to quickly install or remove it by hand without any tools. After the production task is completed, all partitions 701 can be easily removed for independent, thorough soaking, scrubbing, and disinfection, fundamentally ensuring food safety.

[0047] Within each independent conveying channel defined by two adjacent partitions 701, two symmetrically arranged load-bearing plates 703 are installed. These two load-bearing plates 703 are not on the same horizontal plane, but cleverly designed in a stepped shape: one is slightly higher and closer to the channel centerline, while the other is slightly lower and closer to the partition 701. When meat strips fall from above, they preferentially fall onto the higher load-bearing plate 703; once it is full, subsequent meat strips will naturally overflow and be stably caught by the lower load-bearing plate 703. This design greatly improves the material carrying capacity and space utilization within the channel. Furthermore, to address the issue of blood seepage from poultry meat pieces during processing, each load-bearing plate 703 has multiple arrayed drainage channels 704 stamped or cut on its surface. The width and length of these drainage channels 704 are optimized to ensure smooth drainage of blood without allowing small pieces of meat to get stuck or leak, thus achieving synchronous drainage during conveying and improving the quality of the final product.

[0048] To mitigate the impact of meat falling from a height and protect its structure, this invention incorporates a cushioning component 8. Each load-bearing plate 703 is not rigidly fixed between the partitions 701, but rather rotatably connected at a certain angle via two internally embedded pivots 801 and 802. On the inner wall of each partition 701, corresponding to the pivot position of the load-bearing plate 703, a mounting groove 803 is formed, allowing the end of the pivot to slide within a small range. Specifically, at the bottom front end of the mounting groove 803, an adjustment groove 804 is further recessed downwards, containing a pre-installed return spring 805. The end of pivot 801 is slidably connected inside the adjustment groove 804 and abuts against the top of the return spring 805. When the meat falls and impacts, the load-bearing plate 703 causes pivot 801 to move downwards within the adjustment groove 804, thereby compressing the return spring 805. The deformation of the spring absorbs most of the impact energy, providing excellent cushioning. After the impact, the elastic potential energy stored in the return spring 805 is released, gently pushing the load-bearing plate 703 back to its initial horizontal position. The whole process is smooth and rapid.

[0049] After the meat pieces have been buffered and initially arranged, the dynamic leveling mechanism 5 begins to function to ensure a more even distribution. The main body of this mechanism is a horizontally positioned leveling brush 51, its length covering all conveyor channels. The bristles of the leveling brush 51 are made of soft and elastic food-grade nylon, and their length is precisely calculated to ensure that they gently contact and agitate the meat pieces on the support plate 703 during rotation without damaging them or sweeping them out of the channels. The rotational power of the leveling brush 51 comes from a drive motor 522 mounted at one end, which is securely mounted on an adjustable adjustment plate 521 via a retaining ring 523.

[0050] The height adjustment function of the dynamic leveling mechanism 5 is achieved by adjustment component 1 52 and adjustment component 2 53. A rear extension wall 6, serving as a guide rail base, is fixedly connected to the top rear side of the work box 1. Adjustment plate 1 521 can slide up and down on this rear extension wall 6. To lock its height, multiple slots are vertically formed on the plate body of adjustment plate 1 521, and corresponding through holes are provided on the rear extension wall 6. The operator only needs to pull out pin 1 524, move adjustment plate 1 521 to the desired height, and then insert pin 1 524 through the through hole of the rear extension wall 6 and into the selected slot to complete the height setting of that end. Similarly, the other end of the leveling brush 51 is also rotatably connected via adjustment plate 2 531, which moves in a slide rail formed by the inner wall of the work box 1 and the limiting side plate 532. The height of the other end can be locked by the engagement of pin 2 533 with the multiple slots formed on the limiting side plate 532. This dual-end independently adjustable design not only allows for the overall raising and lowering of the brush, but also enables it to be tilted to meet various complex material leveling needs, demonstrating extremely high flexibility and adaptability.

[0051] In summary, the workflow of this invention can be summarized as follows: First, the operator installs the partition 701 and sets the height of the leveling brush 51 according to production needs. After starting the equipment, large pieces of poultry meat are initially cut into strips by the first drive component 4, lifted by the feeding conveyor belt 3, and scattered into various channels of the sorting conveyor belt 7. The buffer component 8 effectively mitigates the impact of the fall, and the drain trough 704 on the load-bearing plate 703 drains excess blood. Subsequently, under the action of the dynamic leveling mechanism 5, the meat strips are arranged to be of uniform thickness and orderly. Finally, these neatly arranged meat strips are finally finely cut by the second drive component 4 at the end of the sorting conveyor belt 7, and the resulting regular meat blocks fall into the discharge conveyor belt 2, completing the entire automated processing flow.

[0052] Please see the appendix Figure 9 The present invention also provides a method for cutting poultry into pieces:

[0053] S1. Preparation and Setup Phase: This phase involves preparation work before the equipment's official operation and is crucial for ensuring smooth processing and that the finished product meets expectations. First, the operator performs a routine pre-start check, including confirming that all safety devices, such as the emergency stop button and safety guards, are in normal working order, and checking the cleanliness of the inside of the work chamber 1 to ensure there are no residues from the previous production run. Next, the channel construction step begins. The operator retrieves clean, dry partitions 701 from the spare parts area according to the meat block specifications required for the day's production. He / she aligns the bottom of the partition 701 with the vertical slot on the mounting base 702 on the outside of the sorting conveyor belt 7 and smoothly inserts it until its bottom is completely flush with the bottom of the slot, ensuring a secure installation. This process can be done by hand without any tools. The operator installs all partitions 701 in sequence, thus creating multiple parallel conveyor channels of uniform width on the sorting conveyor belt 7. Next, the height of the dynamic leveling mechanism 5 is calibrated. The operator needs to set the working height of the leveling brush 51 based on the approximate thickness of the meat piece to be processed, such as whether it is a thicker chicken breast strip or a thinner duck strip. He / she first walks to one side of the equipment and pulls out the locking pin 524, which passes through the rear extension wall 6 and the adjustment plate 521. After being pulled out, the adjustment plate 521 is in a sliding state. The operator moves it up and down to the preset height mark, which corresponds to a specific slot on the rear extension wall 6. After alignment, the pin 524 is reinserted to lock that end. Subsequently, the other end of the adjustment assembly 53 is operated in the same way, setting the height of the adjustment plate 531 by inserting and removing the pin 533. This independent adjustment at both ends ensures that the leveling brush 51 maintains the optimal working distance from the surface of the load-bearing plate 703 of the sorting conveyor belt 7. Finally, the operator uses the integrated control panel to set process parameters such as the running speed of the feeding conveyor belt 3, the sorting conveyor belt 7, and the discharge conveyor belt 2, the rotation speed of the drive motor 402, and the rotation speed of the flattening brush 51 driven by the transmission motor 522. At this point, all preparations are complete, and the equipment is in standby mode.

[0054] S2. Preliminary Cutting Stage: The operator continuously and evenly feeds large pieces of pre-treated poultry meat, such as deboned and skinned meat, into the feed hopper at the top of the working box 1. Under the influence of gravity, the meat pieces fall into the cutting area of ​​the first drive assembly 4. At this time, the drive motor 402 of the drive assembly 4 has started at high speed, and its output torque drives two grid-shaped cutters 404 to rotate at high speed in opposite directions through two meshing transmission gears 403. When the meat pieces pass through the gap between the two cutters 404, they are instantly cut into multiple strips of uniform width by the sharp blades.

[0055] S3, Lifting and Transfer Stage: After initial cutting, the meat strips fall directly onto the surface of the inclined feeding conveyor belt 3 located immediately below. Once the conveyor belt starts, its integral baffles effectively support the meat strips, preventing them from sliding down due to the inclination angle. The feeding conveyor belt 3 steadily lifts and transfers these meat strips from their lower position to their highest point on the upper right at a smooth and continuous speed, preparing them for the next core process.

[0056] S4. Sorting, Buffering, and Draining Stage: After the meat strips are lifted to the highest point of the feeding conveyor belt 3, they will naturally tumble down and enter the sorting conveyor belt 7. During the descent, they are physically separated by the pre-installed partitions 701, ensuring that they fall accurately into different conveying channels and finally land on the load-bearing plate 703 inside the channel. At the moment the meat strips come into contact with the load-bearing plate 703, the core function of the buffer assembly 8 is triggered. The impact force of the meat strips causes the load-bearing plate 703 to rotate slightly downwards. This action is transmitted through its internal rotating shafts 801 and 802. The end of rotating shaft 801 slides downwards in the adjustment groove 804 on the inner wall of the partition 701 and directly compresses the return spring 805 located below it. The elastic deformation of the return spring 805 effectively absorbs the impact energy, achieving a "soft landing" and maximizing the protection of the meat fibers from damage. After the impact, the return spring 805 quickly rebounds, gently pushing the load-bearing plate 703 back to its initial horizontal position, preparing it for the next batch of meat strips. Simultaneously, the draining function operates. As the meat strips remain on and are transported on the load-bearing plate 703, any blood or juices seeping out during cutting flow down the surface and drip quickly through the densely spaced drain grooves 704 on the plate. A collection tray (not shown) below collects this waste liquid, ensuring the meat remains dry.

[0057] S5. Dynamic Leveling Stage: The load-bearing plate 703, carrying the meat strips, continues forward with the sorting conveyor belt 7, entering the working area below the dynamic leveling mechanism 5. At this time, the leveling brush 51, driven by the drive motor 522, is rotating at a set speed. Its soft and resilient bristles penetrate deep into the channel defined by the partition 701, gently sweeping across the top surface of the meat strips. For meat strips that are piled up too high or unevenly arranged, the rotating bristles will move and guide them to the side or in front of the empty space, like combing, so that the height of the meat strips on the entire load-bearing plate 703 tends to be uniform, forming a flat material layer. This step is crucial to ensuring the uniformity of the final cut product size.

[0058] S6. Secondary Fine Cutting Stage: After sorting, buffering, draining, and dynamic leveling, the neatly arranged and uniformly thick meat strips are conveyed to the end of the sorting conveyor belt 7. Here, they will enter the cutting range of the second drive assembly 4. The structure and working principle of this drive assembly 4 are exactly the same as the first. When the neat array of meat strips enters its working area, the high-speed, counter-rotating cutter 404 performs a second and final cut on them. Since the meat strips are arranged longitudinally, this cut is transverse, simultaneously and synchronously cutting all the meat strips in the channels into uniformly long cubes or blocks.

[0059] S7. Finished Product Discharge Stage: After the secondary fine cutting, the poultry meat chunks, now the final finished product, slide down from the end of the load-bearing plate 703 and fall onto the discharge conveyor belt 2 located at the bottom of the equipment. The discharge conveyor belt 2 then transports these processed, distinct meat chunks out of the working box 1, into an external collection box, or directly connects to subsequent seasoning, coating, or packaging equipment. At this point, the entire automated block cutting process is complete.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A method for cutting poultry into pieces, applied to the poultry cutting apparatus according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Preparation stage: Based on the characteristics of the poultry meat pieces to be processed and the final product specifications, make pre-adjustments; the operator inserts and fixes the bottom of multiple partitions (701) into the mounting bases (702) on both sides of the outside of the sorting conveyor belt (7) in sequence, thereby forming multiple independent conveying channels on the sorting conveyor belt (7); then, based on the average thickness of the meat pieces, by adjusting the positions of pins 1 (524) and pins 2 (533) on adjustment component 1 (52) and adjustment component 2 (53) in the corresponding slots, the vertical height of the leveling brush (51) in the dynamic leveling mechanism (5) is set; S2, Preliminary cutting: Start the device and put large pieces of poultry raw meat into the feed port at the top of the working box (1). The raw meat first enters the drive assembly (4) located on the left. The drive motor (402) starts and drives a transmission gear (403) to rotate through its output end. Since the two transmission gears (403) mesh with each other, they drive two cutters (404) to rotate in opposite directions to perform preliminary cutting on the put-in meat pieces and process them into strips. S3, Lifting and Transfer: The strip-shaped meat pieces after initial cutting fall onto the feeding conveyor belt (3) which is inclined to the upper right under gravity. The feeding conveyor belt (3) runs and steadily lifts and transfers the strip-shaped meat pieces to the highest point on the upper right. S4. Sorting, Buffering and Draining: Strip-shaped meat pieces fall from the highest point of the feeding conveyor belt (3) and enter the sorting conveyor belt (7) within the channel defined by the partition (701), and fall onto two symmetrically arranged load-bearing plates (703) within the channel; when the meat pieces fall and contact the load-bearing plates (703), their impact force is transmitted to the buffer assembly (8) through the first rotating shaft (801) and the second rotating shaft (802), causing the load-bearing plates (703) to rotate slightly or sink. The rotating shaft (801) compresses the return spring (805) inside the adjustment groove (804), thereby effectively absorbing the impact energy and preventing damage to the meat. After the impact, the rebound force of the return spring (805) restores the load-bearing plate (703) to the initial horizontal position. At the same time, during the process of the meat staying and being transported on the load-bearing plate (703), the blood water it carries will drip through the multiple drain grooves (704) opened on the load-bearing plate (703) to achieve preliminary drainage. S5. Dynamic leveling: The load-bearing plate (703) carrying the strip-shaped meat pieces continues to be conveyed forward with the sorting conveyor belt (7) and runs to the bottom of the dynamic leveling mechanism (5). At this time, the drive motor (522) drives the leveling brush (51) to rotate. The bristles of the leveling brush (51) contact the surface of the meat pieces on the load-bearing plate (703) to gently sweep and level it, pushing the excessively piled meat pieces to the empty space, so that the thickness of the meat layer on the load-bearing plate in each channel tends to be uniform. S6, Secondary fine cutting: The flattened and arranged strips of meat are transported to the end of the sorting conveyor belt (7) and enter the working range of another drive component (4) located below it. The drive component (4) works in the same way as in step S2, and performs transverse cutting on the neatly arranged strips of meat to precisely cut them into block-shaped finished products of a set length. S7. Finished product discharge: The poultry meat pieces that have been cut into pieces fall from the end of the sorting conveyor belt (7) and land on the discharge conveyor belt (2) located directly below. The discharge conveyor belt (2) transports the finished meat pieces out of the work box (1) for collection or into the next packaging process.
