Description

Technical Field

[0001] The invention relates to the technical field of poultry dicing and processing, in particular to a poultry dicing device and a dicing method. Background Art

[0002] The poultry processing industry is experiencing rapid growth, with growing demand for chicken nuggets for fast-food chains and diced chicken and duck for home-prepared meals. These products place extremely high demands on the uniformity of raw meat size, shape, and weight. To meet this large-scale, standardized production demand, 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 utilizes an assembly line operation model. The basic workflow is as follows: Large, pre-processed chunks of raw poultry meat (such as boneless chicken breast) are fed into the equipment, where they are cut by one or more sets of high-speed rotating cutters. The cut chunks then fall onto a conveyor belt below, which transports them to a discharge port for collection. In some applications where the finished product requires precise form, subsequent sorting or shaping processes are often required.

[0004] However, in the actual operation of the equipment, this type of traditional block cutting equipment has some inherent defects in practical applications that need to be solved urgently.

[0005] A common observation is that after the initial cut, meat chunks often accumulate in a chaotic, disorganized pile on the conveyor belt. This disordered accumulation leads to uneven thicknesses in the material layer. When the meat chunks enter the next cutting station, the cutters are unable to evenly and effectively treat the material. The resulting finished products are naturally of varying sizes and shapes, resulting in a suboptimal product quality rate.

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

[0007] Another daunting issue is equipment cleanliness. The internal structures of many existing machines, particularly those used for partitions or guides, are often welded directly to the frame, forming a fixed, integrated structure. This inevitably creates numerous structural gaps and unsanitary corners. During daily production, meat scraps and grease find their way into these nooks and crannies, making them extremely difficult to thoroughly clean out with a water gun or brush. Over time, these areas become breeding grounds for bacteria, posing a significant risk to the food safety of the final product. Summary of the Invention

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

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

[0019] S1. Preparation: Pre-adjustments are made based on the characteristics of the poultry to be processed and the final product specifications. The operator sequentially inserts and secures the bottoms of multiple partitions into the mounting bases on either side of the sorting conveyor, creating multiple independent conveying channels on the sorting conveyor. The vertical height of the leveling brushes in the dynamic leveling mechanism is then set based on the average thickness of the meat by adjusting the positions of pins 1 and 2 on adjustment components 1 and 2 within their corresponding slots.

[0020] S2. Preliminary Cutting: Start the device and feed large chunks of raw poultry meat into the feed port at the top of the working chamber. The meat first enters the drive assembly on the left. The drive motor starts, and its output drives a transmission gear to rotate. The two transmission gears mesh, driving two cutters to rotate towards each other, performing a preliminary cut on the meat, processing it into strips.

[0021] S3. Lifting and Transferring: After the initial cutting, the strips of meat fall under the action of gravity onto the feeding conveyor belt which is tilted upwards to the right. The feeding conveyor belt runs, steadily lifting and transferring the strips of meat to the highest point in the upper right corner.

[0022] S4. Sorting, buffering and draining: The strips of meat fall from the highest point of the loading conveyor belt, enter the channel defined by the partition on the sorting conveyor belt, and fall onto the two load-bearing plates symmetrically arranged in the channel. When the meat falls and contacts the load-bearing plate, its impact force will be transmitted to the buffer assembly through shaft one and shaft two. The load-bearing plate rotates or sinks slightly, causing shaft one to compress the return spring inside the adjustment groove, thereby effectively absorbing the impact energy and preventing damage to the meat. After the impact, the rebound force of the return spring restores the load-bearing plate to its initial horizontal position. At the same time, while the meat is staying and being transported on the load-bearing plate, the blood it carries will drip through the multiple drain grooves opened on the load-bearing plate to achieve preliminary draining.

[0023] S5. Dynamic Leveling: The load-bearing plate carrying the strips of meat continues forward along the sorting conveyor, moving beneath the dynamic leveling mechanism. At this point, the drive motor drives the leveling brush to rotate. The bristles of the leveling brush come into contact with the surface of the meat on the load-bearing plate, gently sweeping and leveling it, pushing any overly accumulated meat to a more even layer, thereby achieving a more even layer of meat on the load-bearing plate within each channel.

[0024] S6, Secondary Precision Cutting: The flattened and aligned strips are conveyed to the end of the sorting conveyor and into the operating range of another drive assembly located below. This drive assembly operates in the same manner as in step S2, cutting the aligned strips horizontally into precisely defined lengths.

[0025] S7, Finished Product Discharge: The finished poultry pieces fall from the end of the sorting conveyor belt and land on the discharge conveyor belt located directly below. The discharge conveyor belt transports the processed finished meat pieces out of the working box for collection or further packaging.

[0026] The present invention provides a poultry dicing device and dicing method, which have the following beneficial effects:

[0027] 1. In the present invention, the pluggable connection between the partition and the mounting base allows the operator to easily remove all the partitions used to separate the channels by hand after production is completed, and perform independent, corner-free cleaning and disinfection. Compared with the prior art, similar structures are often fixed by welding or bolts, forming a large number of hard-to-reach sanitary dead corners, resulting in the long-term accumulation of meat scraps and grease, and the breeding of bacteria. The solution of the present invention solves this stubborn problem from the root, greatly improving the cleanliness of the equipment, ensuring food safety, and significantly reducing the intensity and time cost of cleaning work.

[0028] 2. In the present invention, a double-layer stepped load-bearing plate structure is adopted, which greatly improves the processing capacity of the material shaping area. When the meat strips fall from a height, the upper load-bearing plate will be filled first. When the upper layer is full, the excess meat strips will naturally overflow by gravity and be caught by the load-bearing plate below. The buffer component can effectively eliminate the impact force when the meat pieces fall, thereby realizing three-dimensional and adaptive filling of the material. Compared with the flat single-layer conveyor belt commonly used in the prior art, its materials are often piled up in one place in a disorderly manner, which not only wastes a lot of effective carrying space, but also brings great difficulties to the subsequent leveling work. The present invention doubles the carrying capacity per unit area and the initial uniform distribution effect of the material through simple structural changes, and is more efficient.

[0029] 3. In the present invention, a dynamic leveling mechanism with adjustable height is provided. The core of the mechanism is a rotating leveling brush, which does not passively block, but actively "combs" and "guides" the meat strips that are piled too high on the load-bearing plate to the empty space. The existing technologies either lack this leveling link, resulting in different sizes of finished products; or use fixed scrapers, which are stiff and cannot adapt to materials of different sizes. The dynamic leveling mechanism of the present invention is not only gentle in action and can protect the meat material, but its height-adjustable design gives the equipment great flexibility, and can perfectly adapt to the processing of different batches and types of poultry meat blocks, thereby ensuring that the final product has extremely high consistency in size and weight.

[0030] 4. The present invention provides a complete set of coherent automation solutions from "shaping and arrangement" to "synchronous precision cutting". From the moment the material enters the sorting conveyor belt, it is always kept in an independent channel defined by the partition, and is arranged in order throughout the process until it is finally cut into blocks by the synchronized cutting knife group. This completely overturns the backward model in the prior art where the meat pieces are piled together in a disorderly manner after the cutting machine discharges the material, and a large number of manual labor is required for secondary sorting and arrangement. The solution of the present invention directly eliminates the high labor cost and low efficiency process of "secondary sorting", and realizes the automated flow operation from raw materials to regular finished products, which not only greatly improves the overall production efficiency, but also avoids the risk of secondary contamination caused by manual handling and contact.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Please see the attached Figure 1 -Attached Figure 8The present invention provides a poultry chunking device whose main structure is integrated into a durable work box 1. Made of stainless steel with a brushed or mirrored surface, this box not only ensures hygienic standards for food processing but also facilitates daily cleaning and maintenance. Multiple feet 11 are evenly spaced at the bottom of the box 1, ensuring stable operation under varying floor conditions and reducing vibrations caused by uneven surfaces.

[0043] Inside the work box 1, the entire processing flow follows the material movement trajectory from left to right and from top to bottom, and the functional units are compactly arranged and smoothly connected. At the upper leftmost part of the device, there is a feed hopper (not shown), below which is the first drive assembly 4 that performs the preliminary cutting task. Following closely behind is a loading conveyor belt 3 that is tilted to the upper right, which is used to lift the meat blocks after the initial cutting. The end point of the loading conveyor belt 3 is just above the starting end of the sorting conveyor belt 7. A dynamic leveling mechanism 5 is arranged across the conveying path of the sorting conveyor belt 7. When the material reaches the end of the sorting conveyor belt 7, another drive assembly 4 for final fine cutting is arranged below it, and the finished product after cutting falls directly onto 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.

[0044] The drive assembly 4 consists of two groups, each with identical structure and function, responsible for the initial and final cutting tasks, respectively. A thickened pad 401 is fixedly attached to the side wall of the work box 1 via high-strength bolts. This pad 401 provides 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 precisely meshes with another transmission gear 403 of the same specifications. The center hole of each transmission gear 403 is coaxially fixedly mounted on the blade shaft of a cutter 404. The cutter 404 is preferably a disc-shaped grid knife made of high-hardness alloy steel, with multiple parallel, sharp blades. When the drive motor 402 is activated, its rotational motion is converted into synchronized, opposite-direction rotational motion by the meshing of a pair of transmission gears 403. This allows the poultry passing through it to be quickly and neatly cut into uniform strips or chunks, achieving high cutting efficiency and a uniform finished product.

[0045] After initial cutting, the strips of meat fall under the influence of gravity onto the surface of the loading conveyor 3. This conveyor 3 features an integrated baffle, with a precisely calculated inclination angle, ensuring that the meat strips neither slide down due to gravity nor are thrown out due to centrifugal force during the lifting process. The discharge end, at its highest point on the upper right, precisely overhangs the sorting conveyor 7, ensuring smooth material transfer to the next station.

[0046] Multiple reinforced mounting bases 702 are welded to the outside of the sorting conveyor 7 frame at equal intervals along the conveying direction. Each mounting base 702 features a vertical slot for the partitions 701. The partitions 701 are designed with mortise and tenon joints that match the slots, allowing operators to quickly install and remove them by hand without any tools. After a production task is completed, all partitions 701 can be easily removed for independent, seamless soaking, scrubbing, and disinfection, fundamentally ensuring food safety.

[0047] Within each independent conveying channel, defined by two adjacent partitions 701, are two symmetrically positioned load-bearing plates 703. These two load-bearing plates 703 are not coplanar, but are cleverly designed in a stepped pattern: one is slightly higher and closer to the channel's centerline, while the other is slightly lower and closer to the partitions 701. When meat strips fall from above, they preferentially land on the higher load-bearing plates 703. Once these plates are full, subsequent strips naturally overflow and are stably caught by the lower load-bearing plates 703 below. This design significantly improves the channel's material carrying capacity and space utilization. Furthermore, to address the issue of blood loss during poultry processing, each load-bearing plate 703 is stamped or cut with a plurality of drain grooves 704 arranged in an array. The width and length of these drain grooves 704 are optimized to ensure smooth drainage while preventing small pieces of meat from becoming stuck or leaking out. This ensures simultaneous drainage during conveyance, improving the quality of the final product.

[0048] To mitigate the impact of falling meat and protect its structural integrity, the present invention incorporates a buffer assembly 8. Each load-bearing plate 703 is not rigidly fixed between the partitions 701. Instead, it is rotatably connected at a certain angle via internally embedded pivots 801 and 802. On the inner wall of each partition 701, corresponding to the pivot of the load-bearing plate 703, a mounting slot 803 is provided, allowing the end of the pivot to slide within a small range. Specifically, the front end of the mounting slot 803 is further recessed to form an adjustment slot 804, which houses a return spring 805. The end of pivot 801 slides snugly within the adjustment slot 804 and abuts the top of the return spring 805. When the meat falls and creates an impact, the load-bearing plate 703 drives pivot 801 downward within the adjustment slot 804, compressing the return spring 805. The deformation of the spring absorbs most of the impact energy and plays an excellent cushioning role. 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 fast.

[0049] After the meat pieces have been buffered and initially arranged, the dynamic leveling mechanism 5 comes into play to ensure a more even distribution. The main body of this mechanism is a horizontally arranged leveling brush 51, whose length covers all conveying 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 as it rotates, it gently contacts and moves the meat pieces on the load-bearing plate 703 without damaging them or sweeping them out of the channel. The rotational power of the leveling brush 51 comes from a transmission motor 522 mounted at one end, which is securely mounted to the adjustable adjustment plate 1 521 via a fixing 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 the guide rail base, is fixedly attached 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 vertical slots are provided on the plate body of adjustment plate 1 521, and corresponding through-holes are provided on the rear extension wall 6. The operator simply pulls out latch 1 524, moves adjustment plate 1 521 to the desired height, and then inserts latch 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 within the 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 latch 2 533 engaging the multiple slots provided on the limiting side plate 532. This double-ended independently adjustable design not only allows the brush to be raised and lowered as a whole, but can even be tilted to meet various complex material leveling requirements, with extremely high flexibility and adaptability.

[0051] In summary, the workflow of the present invention can be summarized as follows: the operator first installs the partition 701 and sets the height of the leveling brush 51 according to production requirements. After starting the equipment, the large pieces of poultry meat are initially cut into strips by the first drive component 4, lifted by the loading conveyor belt 3, and scattered into the various channels of the sorting conveyor belt 7. The buffer component 8 effectively resolves the impact of falling, 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 with uniform thickness and orderly arrangement. Finally, these neatly arranged meat strips are finally fine-cut by the second drive component 4 at the end of the sorting conveyor belt 7, and the regular meat blocks formed fall into the discharge conveyor belt 2, completing the entire automated processing flow.

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

[0053] S1. Preparation and Setup: This stage is the preparatory work before the equipment officially begins operation and is crucial for ensuring a smooth processing process and that the finished product meets expectations. First, the operator performs a routine pre-startup inspection, confirming that all safety devices, such as the emergency stop button and safety shield, are in proper working order. The operator also checks the cleanliness of the interior of the work box 1 to ensure there are no residues from previous production. The operator then proceeds to the channel construction step. Based on the meat specifications required for the day's production, the operator obtains clean, dry partitions 701 from the spare parts area. The operator aligns the bottom of the partition 701 with the vertical slots on the mounting base 702 on the outside of the sorting conveyor belt 7 and smoothly inserts it until the bottom is fully seated, ensuring a secure fit. This process requires no tools and can be performed manually. The operator sequentially installs all partitions 701, thereby creating multiple, parallel conveying 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 according to the approximate thickness of the meat to be processed, for example, whether it is thicker chicken breast strips or thinner duck strips. He / she first walks to the 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, and the operator moves it up and down to the preset height scale line, which corresponds to a specific slot on the rear extension wall 6. After alignment, the pin 524 is reinserted to complete the locking of this end. Subsequently, the adjustment component 2 53 at the other end is operated in the same way, and the height of the adjustment plate 2 531 is set by plugging and unplugging the pin 2 533. Through this independent adjustment at both ends, it can be ensured that the leveling brush 51 maintains an optimal working distance from the surface of the load-bearing plate 703 of the sorting conveyor belt 7. Finally, the operator uses the equipment's integrated control panel to set process parameters such as the operating speed of the loading 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 leveling 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 chunks of pre-processed poultry meat, such as those that have been boned and skinned, into the feed hopper at the top of the working box 1. Under the influence of gravity, the meat chunks fall into the cutting area of ​​the first drive assembly 4. At this point, the drive motor 402 of this drive assembly 4 is energized at high speed. The torque it generates, through two meshing transmission gears 403, drives two grid-shaped cutting blades 404 to rotate in opposite directions at high speed. As the meat chunks pass through the gap between the two cutting blades 404, the sharp blades instantly cut them into multiple strips of uniform width.

[0055] S3, Lifting and Transfer Stage: The initially cut meat strips fall directly onto the inclined loading conveyor belt 3 immediately below. Once the conveyor belt is activated, its integrated baffles effectively support the strips, preventing them from sliding downward due to the inclined angle. At a steady and continuous speed, the loading conveyor belt 3 steadily lifts and transfers the strips from a lower position to its highest point, above and to the right, ready for the next core process.

[0056] S4, sorting, buffering and draining stage: When the meat strips are lifted to the highest point of the feeding conveyor belt 3, they will naturally fall down and enter the range of the sorting conveyor belt 7. During the falling process, they are physically separated by the installed partitions 701 to ensure that they fall accurately into different conveying channels and eventually fall on the load-bearing plate 703 inside the channel. At the moment when 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 downward, and this action is transmitted through the internal rotating shaft 1 801 and rotating shaft 2 802. Among them, the end of the rotating shaft 1 801 slides downward in the adjustment groove 804 on the inner wall of the partition 701, and directly compresses the reset spring 805 located below it. The elastic deformation of the reset spring 805 effectively absorbs the impact energy, achieves a "soft landing", and protects the meat fibers from damage to the greatest extent. After the impact, the return spring 805 quickly rebounds, gently pushing the load-bearing plate 703 back to its initial horizontal position, ready for the next batch of meat strips. Simultaneously, the drain function operates simultaneously. As the meat strips rest and are transported on the load-bearing plate 703, any blood or juice exuded during cutting flows along the plate surface and rapidly drips through the densely arranged drain troughs 704 on the load-bearing plate 703. A water collection tray (not shown) collects this waste liquid, ensuring the meat remains dry.

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

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

[0059] S7, Finished Product Discharge: After the second fine-cutting phase, the finished poultry chunks slide down the end of the load-bearing plate 703 and fall onto the discharge conveyor 2 at the bottom of the equipment. The discharge conveyor 2 then transports the processed, clearly granulated chunks out of the working box 1, into an external collection bin or directly to subsequent seasoning, coating, or packaging equipment. This completes the automated chunking process.

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

10. The poultry dicing method according to claim 1, applied to a poultry dicing device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Preparation stage: Preliminary adjustments are made based on the characteristics of the poultry meat to be processed and the specifications of the final product. The operator sequentially plugs and fixes the bottoms of multiple partitions (701) into the interior of the mounting bases (702) on both sides of the outside of the sorting conveyor (7), thereby forming multiple independent conveying channels on the sorting conveyor (7). Subsequently, the vertical height of the leveling brush (51) in the dynamic leveling mechanism (5) is set by adjusting the positions of the first latch (524) and the second latch (533) on the adjustment component (52) and the adjustment component (53) in the corresponding slots according to the average thickness of the meat. S2. Preliminary cutting: The device is started and a large piece of raw poultry meat is fed 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 side. The drive motor (402) is started and drives a transmission gear (403) to rotate through its output end. As the two transmission gears (403) mesh with each other, they drive the two cutters (404) to rotate in opposite directions, performing preliminary cutting on the fed meat piece and processing it into strips. S3, lifting and transporting: The strips of meat after the initial cutting fall under the action of gravity onto the feeding conveyor (3) arranged at an upper right angle. The feeding conveyor (3) runs and stably lifts and transports the strips of meat to the highest point at the upper right. S4. Sorting, buffering and draining: The strips of meat fall from the highest point of the feeding conveyor belt (3), enter the channel defined by the partition (701) on the sorting conveyor belt (7), and fall onto the two load-bearing plates (703) symmetrically arranged in the channel. When the meat falls and contacts the load-bearing plates (703), its impact force is transmitted to the buffer assembly (8) through the rotating shaft 1 (801) and the rotating shaft 2 (802). The load-bearing plate (703) rotates or sinks slightly, causing the rotating shaft 1 (801) to compress the return spring (805) inside the adjustment groove (804), thereby effectively absorbing the impact energy and preventing the meat from being damaged. After the impact, the rebound force of the return spring (805) restores the load-bearing plate (703) to its initial horizontal position. At the same time, during the process of the meat pieces staying and being transported on the load-bearing plate (703), the blood carried by the meat pieces will drip through the multiple drain grooves (704) provided on the load-bearing plate (703), thereby achieving preliminary draining. S5. Dynamic leveling: The load-bearing plate (703) carrying the strips of meat continues to be transported forward along the sorting conveyor belt (7) and moves to the bottom of the dynamic leveling mechanism (5). At this time, the transmission motor (522) drives the leveling brush (51) to rotate. The bristles of the leveling brush (51) come into contact with the surface of the meat on the load-bearing plate (703), gently sweeping and leveling it, pushing the meat that is piled too high 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 Precision Cutting: The flattened and aligned strips of meat are conveyed to the end of the sorting conveyor belt (7) and enter the working range of another drive assembly (4) located below it. The drive assembly (4) here operates in the same manner as step S2, cutting the aligned strips of meat horizontally and accurately into finished blocks of a set length. S7, finished product discharge: The finally cut poultry meat pieces fall from the end of the sorting conveyor belt (7) and fall onto the discharge conveyor belt (2) located directly below. The discharge conveyor belt (2) transports the processed finished meat pieces out of the working box (1) for collection or entering the next packaging process.
