Description

Technical Field

[0001] This application relates to the field of food processing machinery technology, and more specifically, to a trimming machine for automatically feeding chicken breast and leg meat. Background Technology

[0002] Poultry products, especially chicken breast and leg meat, occupy an important position in the food consumption market due to their high protein and low fat nutritional advantages. On large-scale food processing production lines, to meet the requirements of subsequent deep processing stages such as marinating, coating, and shaping, or to adapt to standardized packaging specifications for direct market consumption, thawed or fresh chicken breast and leg meat must undergo precise trimming and cutting to obtain meat pieces with regular shapes, uniform thickness, and consistent weight. This process directly affects the uniformity of the product's appearance, the stability of the cooking process, and the operational efficiency of automated packaging lines, making it a key link in improving overall production quality.

[0003] Currently, the industry generally employs two shaping and processing methods: manual operation, which relies on workers using knives on a workbench to manually trim, cut, and shape the meat. This method is not only extremely labor-intensive and inefficient, but also suffers from significant product specification fluctuations and difficulty in controlling yield due to over-reliance on the operator's personal experience. It also carries risks of microbial contamination and knife safety hazards. Semi-automatic mechanical assistance achieves partial automation through simple conveyor belts and fixed or easily adjustable cutting devices. However, when faced with the significant differences in individual chicken shapes and the soft, easily deformable texture of chicken meat, the equipment falls short. Specifically, it cannot effectively fix and shape irregular pieces of meat before cutting, resulting in rough cut surfaces and low finished product qualification rates; it lacks a pre-treatment mechanism to standardize the hardness or shape of meat pieces, leading to decreased cutting accuracy; furthermore, the system's automation level is limited, still requiring frequent manual intervention in steps such as feeding, positioning, and material transfer, preventing continuous and efficient assembly line operations and severely restricting production efficiency and product consistency.

Detailed Implementation

[0024] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] In large-scale food processing, the trimming and cutting of chicken breast and leg meat faces technical challenges due to the tender and easily deformable texture of the meat and the large differences in individual shapes. Existing technologies struggle to fix the meat pieces and ensure their regular shape before cutting, resulting in uneven cut surfaces and reduced yield. Furthermore, the lack of a uniform pretreatment mechanism for meat hardness affects cutting accuracy. In addition, insufficient automation necessitates manual loading, positioning, and transfer operations, leading to decreased production efficiency and inconsistent product specifications.

[0027] For example, on a chicken breast processing production line, thawed chicken breasts are manually placed on the feeding conveyor belt. Due to the irregular shape of the meat pieces, the semi-automatic cutting device cannot adapt to individual differences. During the cutting process, the meat pieces shift, resulting in irregular cuts. At the same time, uneven temperature distribution of the meat pieces causes some areas to be too soft, resulting in tearing at the edges after cutting. Operators need to perform secondary trimming, which prolongs the processing cycle and increases the frequency of manual intervention.

[0028] If the above problems are not resolved, it will lead to inconsistent product specifications, affecting the continuity of subsequent marinating and packaging processes; increase food safety risks, such as potential hazards in knife management; reduce the overall automation level of the production line, and hinder the realization of fully automated assembly line operations.

[0029] Please see Figures 1 to 7As shown, this application proposes an automatic chicken breast and leg trimming machine, including a feeding conveyor belt 1. A thickness flattening component 2 is provided at the rear end between the left and right support plates of the feeding conveyor belt 1. A freezing conveyor belt 3 is connected to the discharge port of the feeding conveyor belt 1. A freezer 4 for freezing chicken is sleeved in the middle of the freezing conveyor belt 3. A U-shaped support frame 5 is connected to the rear of the freezing conveyor belt 3. Chain conveyor belts 51 are provided on the inner sides of the two vertical plates of the U-shaped support frame 5. Multiple conveyor plates 53 are connected and fixed between the chain conveyor belts 51 at the left and right ends by a first bolt 52. Chicken trimming and cutting grooves 54 are opened on the left and right ends of the upper surface of the conveyor plate 53. A transfer component 6 for transferring frozen chicken to the chicken trimming and cutting grooves 54 is provided at the rear end of the freezing conveyor belt 3. A cutting component 7 for trimming and cutting chicken is sleeved on the outer side of the U-shaped support frame 5.

[0030] For ease of understanding, the following explains some key terms in this embodiment: Feeding conveyor belt: This conveyor belt is used to carry the chicken to be processed and transport it from the feeding area to the subsequent processing station. Its main function is to achieve the initial conveying of the chicken.

[0031] Thickness flattening component: This component is located at the rear end of the feeding conveyor belt and is used to pre-treat the thickness of the chicken meat during transportation, so that it achieves a relatively uniform thickness, providing consistent input conditions for subsequent freezing and cutting processes.

[0032] Freezing Conveyor Belt: This conveyor belt receives the chicken from the loading conveyor belt and carries it into the freezing area. The conveyor belt itself is typically designed to withstand low-temperature environments and effectively transfer cold energy.

[0033] Freezer: This equipment is used in conjunction with a freezing conveyor belt to quickly freeze chicken on the conveyor belt, thereby increasing the firmness of the chicken and facilitating subsequent trimming and cutting.

[0034] U-shaped support frame: This support frame provides structural support for the entire trimming and cutting area. Its internal space is used to accommodate the chain conveyor belt and conveyor plate, and to support the cut parts.

[0035] Chain conveyor belt: This conveyor belt is set on the inner side of the two vertical plates of the U-shaped support frame. Through chain drive, it drives multiple conveyor plates to move, thereby transporting chicken to different processing positions.

[0036] Conveyor plate: This plate is fixed between the chain conveyor belts at the left and right ends by the first bolt. The upper surface of the plate is provided with a chicken trimming and cutting groove to support and position the chicken for trimming and cutting.

[0037] Chicken trimming and cutting groove: This groove is formed on the upper surface of the conveyor plate. Its shape and size match the target trimmed chicken pieces and are used to position and support the chicken during the cutting process.

[0038] Transfer component: This component is located at the rear end of the frozen conveyor belt and is used to accurately transfer frozen chicken from the frozen conveyor belt into the chicken trimming and cutting slot.

[0039] Cutting component: This component is fitted on the outside of the U-shaped support frame and is used to precisely cut the chicken placed in the chicken trimming cutting groove to obtain pieces of meat of the desired shape and size.

[0040] This embodiment provides an automatic chicken breast and leg meat trimming machine, the main technical features of which are implemented as follows: The feeding conveyor belt can be implemented in two ways: First, a simple flat belt conveyor mechanism can be used, with a motor driving the belt to circulate and transport the chicken, which is manually placed at the front end of the conveyor belt, to the rear end. Second, a roller conveyor belt can be used, where a series of rotating rollers propels the chicken forward.

[0041] The thickness flattening component can be implemented by: setting a pressure plate at a fixed height between the left and right support plates of the feeding conveyor belt at the rear end; when the chicken passes under the pressure plate, its thickness is forcibly flattened. Alternatively, a pair of manually adjustable rollers can be used, with the operator manually adjusting the roller spacing according to the initial thickness of the chicken to achieve flattening.

[0042] One way to implement a freezing conveyor belt is to place a regular mesh conveyor belt in a low-temperature environment, such as above a refrigerator or a container filled with ice. As the chicken moves along the conveyor belt, it freezes through contact with the low temperature. Alternatively, a metal plate conveyor belt with coolant circulation pipes can be used, where the flow of coolant removes heat from the chicken.

[0043] The refrigeration system can be implemented in two ways: First, an industrial refrigeration unit is used, with refrigerant piped to the area below or above the refrigeration conveyor belt to lower the temperature in that area. Second, a simple air-cooling system can be used, where a fan blows cool air onto the chicken on the conveyor belt.

[0044] The U-shaped support frame can be implemented in two ways: using a welded steel frame structure, with its two vertical plates and horizontal plate forming a stable U-shape to support the internal transmission mechanism and the external cutting mechanism; or, using a frame constructed from bolted aluminum alloy profiles.

[0045] The chain conveyor belt can be implemented by installing two parallel chains on the inner sides of the two vertical plates of the U-shaped support frame, and driving the chains to circulate through sprockets. Alternatively, a toothed belt conveyor can be used, achieving synchronous transmission through the meshing of the toothed belt and gears.

[0046] The conveyor plate can be implemented in two ways: First, multiple independent flat plates can be used, connected to the chain conveyor belts at both ends via simple hooks or clips, moving with the chain. Second, a single-piece molded plastic plate can be used, with holes pre-drilled at both ends for connection to the chain.

[0047] The chicken trimming and cutting groove can be implemented by: stamping or milling a groove of a predetermined shape on the upper surface of the conveyor plate using a die to hold and position the chicken. Alternatively, a detachable die block can be used and fixed to the conveyor plate to accommodate the trimming needs of chickens of different shapes.

[0048] The transfer mechanism can be implemented in two ways: First, a simple pusher mechanism can be used. When the frozen chicken reaches the rear end of the freezing conveyor belt, the pusher pushes the chicken laterally into the chicken trimming and cutting slot. Second, a robotic arm with suction cups can be used, which is manually operated to pick up the chicken from the freezing conveyor belt and place it into the cutting slot.

[0049] The cutting mechanism can be implemented as follows: A fixed-position blade holder is installed on the outside of the U-shaped support frame, and a blade matching the shape of the chicken trimming cutting groove is fixed on the blade holder. When the conveyor plate moves below the blade, the blade is manually pressed down to cut. Alternatively, a cylinder-driven cutter can be used, with the cylinder's extension and retraction driving the cutter to make up-and-down cutting movements.

[0050] The following example will provide a more detailed explanation of the above technical solution: Imagine a food processing plant that needs to standardize the cutting and shaping of a batch of irregularly shaped chicken breasts with varying thicknesses. First, operators place the unprocessed chicken breasts on a conveyor belt. Once the conveyor belt starts, the chicken breasts are transported to its rear end. At this rear end, a thickness flattening device performs initial thickness straightening on the chicken breasts, ensuring a relatively uniform thickness before proceeding to subsequent processes. This step effectively solves the problem of inconsistent original chicken shapes, laying the foundation for precise processing later.

[0051] The chicken breasts, after being flattened, are then conveyed to a freezing conveyor belt. A freezer is installed in the middle of this conveyor belt, which rapidly freezes the chicken breasts. Freezing hardens the chicken breasts, preventing deformation and uneven cuts caused by soft meat during cutting, significantly improving cutting accuracy and yield.

[0052] The frozen chicken breasts continue moving to the rear end of the freezing conveyor belt, where the transfer unit comes into play. This unit accurately picks up the frozen chicken breasts from the conveyor belt and places them into the chicken trimming and cutting slots on the conveyor plate inside the U-shaped support frame. The shape of the chicken trimming and cutting slots corresponds to the target trimmed chicken pieces, ensuring precise alignment and fixation of the chicken before cutting and preventing displacement during the cutting process.

[0053] After the chicken meat is accurately placed into the chicken trimming and cutting slot, the chain conveyor belts on the inner sides of the two vertical plates of the U-shaped support frame drive multiple conveyor plates to move, transporting the conveyor plates carrying the chicken meat to the cutting area. In this area, the cutting device, which is sleeved on the outer side of the U-shaped support frame, is activated. According to a preset program, the cutting device precisely trims and cuts the chicken meat in the trimming and cutting slot. Because the chicken meat has been frozen and is hardened, and is effectively fixed in the cutting slot, the cutting device can efficiently and accurately complete the cutting, obtaining chicken pieces with regular shapes and uniform sizes. The entire process achieves fully automated and continuous operation from feeding, flattening, freezing, transfer to cutting. The various technical features work together closely to solve the problems of low efficiency, poor precision, and insufficient automation in chicken trimming processing.

[0054] Based on the above examples, the automatic chicken breast and leg trimming machine provided in this embodiment demonstrates significant technological contributions. Compared to traditional manual operation, this application achieves full automation of the chicken trimming process by introducing a series of automated components, including a feeding conveyor belt, a thickness flattening component, a freezing conveyor belt, a freezer, a transfer component, a U-shaped support frame, a chain conveyor belt, a conveyor plate, a chicken trimming and cutting groove, and a cutting component. This completely changes the problems of high labor intensity, low production efficiency, inconsistent product specifications, and food safety hazards associated with relying on manual trimming in the past.

[0055] Specifically, the thickness flattening component effectively solves the problem of uneven original chicken thickness, providing a uniform input for subsequent standardized processing. This contrasts sharply with the shortcomings of existing semi-automatic equipment, which struggles to effectively standardize irregularly shaped meat pieces before cutting. The combination of the freezing conveyor belt and the freezer ensures the chicken achieves suitable hardness before cutting, significantly improving cutting precision and efficiency, avoiding deformation and uneven cut surfaces caused by soft meat, thereby increasing the yield. This compensates for the lack of effective pretreatment methods in existing technologies to standardize meat hardness.

[0056] Furthermore, the introduction of the transfer component enables precise transfer of frozen chicken to the trimming and cutting slot. Combined with the positioning function of the trimming and cutting slot, accurate alignment before cutting is ensured. The automated operation of the cutting component further guarantees the regularity and consistency of the cuts. The entire system, driven by a chain conveyor belt, achieves continuous and efficient flow of chicken between different processes, overcoming the limitations of existing semi-automatic equipment, which suffers from poor automation and continuity, and still requires a large amount of manual labor for loading, positioning, and transfer. Therefore, the trimming machine in this embodiment can stably produce standardized chicken products with regular shape, uniform thickness, and consistent weight, significantly improving processing efficiency and product quality, and providing an advanced solution for large-scale food processing.

[0057] In some other embodiments, this application proposes an automatic chicken breast and leg shaping machine, in which a thickness flattening component is provided at the rear end between the left and right support plates of the feeding conveyor belt. However, in actual operation, if the structure and driving method of the thickness flattening component are not clearly defined or optimized, it may lead to uneven flattening of the chicken meat thickness, thereby affecting the subsequent processing accuracy and efficiency.

[0058] Please continue reading. Figures 1 to 3 As shown, this application further proposes that the aforementioned thickness flattening component 2 includes a flattening roller 21, and a support rod 22 is provided at the rear end of the outer side of the left and right support plates of the feeding conveyor belt 1. A fixed cover 24 is connected to the support rod 22 by a second bolt 23. A plurality of flattening rollers 21 are arranged at equal intervals inside the fixed cover 24. A driving component 8 for driving the flattening roller 21 is provided on the outer side of the left support plate of the feeding conveyor belt 1.

[0059] The flattening roller is a cylindrical or conical rotating component that applies pressure to the chicken entering the shaping machine, making its thickness uniform or its surface flat. The flattening roller can be made of metal (such as stainless steel) with a polished surface to reduce adhesion to the chicken and facilitate cleaning; alternatively, it can be a composite structure with a metal core encased in a polymer material (such as polyurethane or silicone) to provide elasticity, better adapt to the irregular shape of the chicken, and avoid damage. Support rods are used to fix and support the thickness flattening components, ensuring their stability and accuracy during operation. Support rods can be solid cylindrical or square cross-section metal rods, fixed to the rear end of the left and right support plates of the feeding conveyor belt by welding or bolting; alternatively, the support rods can be profiles with a certain strength and rigidity, such as L-shaped or U-shaped steel, with one end fixed to the support plate and the other end used to support the fixing cover. A second bolt is a fastener used to connect and fix the fixing cover to the support rod, providing a reliable mechanical connection. The second bolt can be a standard hex bolt with a nut, with pre-tightening force ensuring a secure connection; alternatively, the second bolt can be an internal hex bolt or countersunk bolt, directly screwed into the support rod or fixing cover with threaded holes to achieve a more compact structure or avoid protrusions. The fixing cover houses and protects the flattening roller, providing a mounting base for the roller and potentially serving as a dust and splash protector. The fixing cover can be a box-shaped or U-shaped structure, made of sheet metal (such as stainless steel) through bending, welding, or riveting, with bearing housing holes inside for mounting the bearings of the flattening roller; alternatively, the fixing cover can be a structure manufactured using casting or integral molding processes, offering higher overall rigidity and precision, with its internal structure optimized according to the arrangement of the flattening roller. The drive component is a device that provides power to the mechanical system, enabling its movement. In this application, the drive component is used to drive the flattening roller to rotate, thereby flattening the chicken meat. The drive unit can be an electric motor that transmits power to the flattening rollers through a reducer and transmission mechanism (such as gears, chains, or belts); or it can be a hydraulic motor or a pneumatic motor that provides power through a hydraulic or pneumatic system, suitable for applications requiring high torque or explosion-proof environments.

[0060] This application's solution addresses the problem of uneven chicken thickness flattening by specifying the thickness flattening component as a structure including flattening rollers, support rods, second bolts, a fixed cover, and a drive unit. Specifically, the thickness flattening component comprises multiple flattening rollers evenly spaced within the fixed cover. The fixed cover is securely connected to the support rods located at the rear end of the outer sides of the left and right support plates of the feeding conveyor belt via second bolts, providing a stable mounting base and support for the flattening rollers. When the chicken is conveyed to the area below the thickness flattening component via the feeding conveyor belt, the drive unit located on the outer side of the left support plate of the feeding conveyor belt is activated, driving the flattening rollers to rotate. Because the flattening rollers are evenly spaced, they can apply uniform pressure to the passing chicken, flattening its thickness to a preset value. This structural design ensures uniform contact area and pressure distribution between the flattening rollers and the chicken, avoiding localized over- or under-pressure. In this way, the thickness of the chicken can be effectively and uniformly controlled before entering the freezing conveyor belt for freezing processing, laying the foundation for subsequent precise freezing and trimming cutting. Compared to simply setting up an abstract thickness flattening component, this solution makes the chicken flattening process more controllable and efficient by clearly defining the structure of the flattening roller, its equidistant arrangement within the fixed cover, and the power provided by the drive component. This significantly improves the consistency of chicken thickness, thereby enhancing the processing accuracy and product quality of the entire shaping machine.

[0061] The following is a concrete example illustrating the thickness flattening component. Specifically, the aforementioned flattening component comprises three flattening rollers made of stainless steel with a finely polished surface. These rollers are mounted via bearings within a fixed housing welded from stainless steel plates. The housing has a U-shaped structure, with its opening facing the feeding direction. The two sides of the fixed housing are fixed to two solid round steel support rods with a diameter of 20mm via four M8 bolts. These support rods are welded to the rear ends of the left and right support plates of the feeding conveyor belt. The driving component is an AC servo motor, mounted on the outer side of the left support plate of the feeding conveyor belt. This servo motor is connected to the shaft end of one of the flattening rollers via a gear reducer and a chain drive mechanism, thereby driving all the flattening rollers to rotate synchronously. When the chicken slices are conveyed by the feeding conveyor belt to the area below the flattening rollers, the servo motor drives the rollers to rotate at a preset linear speed, applying uniform downward pressure to the chicken slices and flattening their thickness to, for example, 10mm.

[0062] The above technical solution concretizes the thickness flattening component into a structure including a flattening roller, support rod, second bolt, fixing cover, and drive component, thus solving the problem of uneven chicken thickness flattening. The equidistant arrangement of the flattening rollers ensures uniform pressure applied to the chicken, avoiding flattening defects caused by unclear structure or improper drive. The introduction of the drive component allows the flattening rollers to rotate stably and controllably, ensuring the continuity and consistency of the flattening process. This well-defined structure and drive method enable the chicken to achieve a highly consistent thickness before entering the subsequent freezing and trimming / cutting stages, thereby significantly improving freezing efficiency and cutting accuracy, ultimately enhancing the overall processing quality and product qualification rate of the trimming machine.

[0063] In some embodiments described above in this application, a thickness flattening component is proposed, including a flattening roller, and a driving component for driving the flattening roller is provided on the outer side of the left support plate of the feeding conveyor belt. However, in its implementation, how to ensure that the driving component can stably and reliably drive multiple flattening rollers and effectively protect the driving mechanism from the influence of the external environment is a problem that needs further consideration.

[0064] Please continue reading. Figure 2 As shown, this application further proposes that the driving component 8 includes a first motor (not shown), a driving wheel is provided on the output shaft of the first motor, the driving wheel is connected to the end of the flattening roller 21 via a transmission chain, and the first motor is covered by a protective cover 81.

[0065] Specifically, the first motor is a device that converts electrical energy into mechanical energy, providing rotational power to the pressing rollers. The first motor can take various forms, such as an AC asynchronous motor, a DC brushless motor, or a servo motor; the specific choice depends on factors such as required torque, speed accuracy, and operating environment. The drive wheel, mounted on the output shaft of the first motor, transmits the motor's rotational motion to the drive chain. The drive wheel is typically a sprocket, its teeth matching the pitch of the drive chain to ensure smooth and efficient power transmission. The drive chain is a flexible transmission element composed of a series of links, used to transmit the power from the drive wheel to the end of the pressing rollers. The drive chain enables synchronous driving of multiple pressing rollers, ensuring uniform force on the chicken during pressing. The drive chain can be a roller chain, sleeve chain, or toothed chain, to adapt to different load and speed requirements. The protective cover is a shell used to cover and protect the first motor. The protective cover effectively prevents external impurities such as dust, moisture, and oil from entering the interior of the primary motor, while also preventing operators from accidentally coming into contact with high-speed rotating motor components, thereby improving the safety and reliability of the equipment. The protective cover can be made of metal sheet (such as stainless steel or aluminum alloy) or high-strength engineering plastics, and can be designed as a sealed or semi-sealed structure as needed.

[0066] This application's solution achieves stable driving of the flattening rollers by specifying the driving component as a combination of a first motor, a drive wheel, and a transmission chain, supplemented by a protective cover. The first motor provides power, and the drive wheel on its output shaft transmits power to the ends of multiple flattening rollers via the transmission chain, enabling all flattening rollers to rotate synchronously, thereby uniformly flattening the chicken meat. The connection method of the transmission chain ensures the reliability and efficiency of power transmission. Simultaneously, the first motor is covered by the protective cover, protecting the motor and its transmission components from external environmental corrosion and physical damage, ensuring long-term stable operation of the equipment and operator safety. This structural design makes the entire thickness flattening mechanism's drive system more integrated, efficient, and durable.

[0067] The following is a specific example. As a concrete implementation, the first motor can be a three-phase AC asynchronous motor, of the Y-series type, suitable for industrial environments. The drive wheel can be a sprocket matched with the transmission chain, its tooth profile and pitch conforming to the chain standard, and its material being high-strength alloy steel. The transmission chain can be a roller chain conforming to national standards, possessing good wear resistance and tensile strength. The protective cover can be a box structure made of stainless steel plate, possessing good corrosion resistance and equipped with necessary sealing structures to provide dust and water protection.

[0068] Through the above technical solution, the present application's solution ensures that multiple flattening rollers receive stable and synchronized driving force, thereby achieving precise and uniform flattening of the chicken meat's thickness. The use of a transmission chain makes power transmission efficient and reliable, and easy to maintain. Simultaneously, the protective cover effectively isolates dust, moisture, and other impurities from the external environment, protecting the primary motor and transmission mechanism, significantly extending the equipment's service life, improving operational safety, avoiding malfunctions caused by external factors, and ensuring the continuous and stable operation of the production line.

[0069] In some embodiments described above in this application, an automatic chicken breast and leg meat trimming machine is proposed, which freezes the chicken meat via a feeding conveyor belt, a freezing conveyor belt, and a freezer. However, after the chicken meat undergoes rapid cooling, its temperature may be too low, causing the meat to become too stiff or brittle. This not only affects the efficiency and accuracy of subsequent trimming and cutting but may also adversely affect the quality of the chicken meat, and may even produce debris or irregular fracture surfaces during the cutting process.

[0070] Please continue reading. Figures 1 to 3 As shown, this application further proposes that the frozen conveyor belt 3 has multiple strip-shaped air vents 31 evenly spaced on the conveyor belt body, and a heater 32 is provided at the rear end of the frozen conveyor belt 3, so as to warm the chicken after rapid cooling back to 0 degrees Celsius.

[0071] The freezing conveyor belt features multiple evenly spaced strip-shaped vents. These vents, openings on the conveyor belt, facilitate gas flow. During the chicken's rewarming process, these vents help distribute the hot air generated by the heater evenly across the chicken surface, ensuring efficient and uniform heat transfer. One implementation method is to use regular rectangular or elliptical holes, formed on the conveyor belt material through processes such as stamping or laser cutting. Another method is to design the vents as a mesh or honeycomb structure to increase the ventilation area while maintaining the conveyor belt's structural strength and load-bearing capacity. A heater is located at the rear end of the freezing conveyor belt. This heater generates heat and is primarily used to rewarm the frozen chicken. One implementation method is to use an electric heating element or a PTC heating element, working in conjunction with a hot air circulation system to transfer heat to the chicken through forced convection. Another approach is to use an infrared heater to directly heat the surface of the chicken through radiation, achieving rapid and efficient warming. This combination of technologies allows the rapidly cooled chicken to be warmed back to 0 degrees Celsius. This temperature is crucial for subsequent processing, maintaining the firmness of the meat while preventing it from becoming too hard or brittle due to excessively low temperatures, thus facilitating shaping and cutting.

[0072] This application's solution achieves precise rewarming of rapidly cooled chicken by creating multiple equally spaced strip-shaped vents on the conveyor belt of a freezing conveyor and installing a heater at the rear end of the conveyor belt. After the chicken undergoes rapid cooling on the freezing conveyor belt, its temperature drops significantly. To optimize subsequent shaping and cutting, the frozen chicken continues to move forward with the conveyor belt into the heater's operating area. At this point, the heater activates, generating heat. This heat is evenly and efficiently transferred to all surfaces of the chicken through the strip-shaped vents on the conveyor belt. The strip-shaped vent design ensures sufficient hot air circulation, preventing localized overheating or uneven heating, thus guaranteeing the stability and consistency of the rewarming process. By precisely controlling the heater's power and operating time, combined with the conveyor belt's speed, the temperature of the rapidly cooled chicken can gradually rise and eventually stabilize at around 0 degrees Celsius. This temperature point allows the chicken to maintain good shaping ability while possessing moderate firmness, avoiding cutting difficulties or meat damage caused by excessive hardness. It provides an ideal physical state for subsequent shaping and cutting, thus effectively solving the problem of chicken affecting processing quality due to over-freezing.

[0073] The following is a concrete example: the conveyor belt of the freezing conveyor can be made of polyurethane material, which has good low-temperature resistance and food safety. The equally spaced strip-shaped vents on the belt can be rectangular holes approximately 40 mm long and 6 mm wide, with a spacing of 80 mm to ensure sufficient ventilation area and the structural integrity of the conveyor belt. The heater can use a set of 1.5 kW electric heating tubes, combined with a small axial flow fan to form a hot air circulation system, installed below the freezing conveyor belt. Hot air is blown upwards, passing through the strip-shaped vents to heat the chicken. To precisely control the rewarming temperature, an infrared temperature sensor can be installed above the heating area to monitor the surface temperature of the chicken in real time and feed the data back to the controller. The controller automatically adjusts the power output of the heater and / or the operating speed of the freezing conveyor based on the preset target temperature of 0 degrees Celsius to achieve precise rewarming.

[0074] The above technical solution enables precise temperature control of the chicken after rapid cooling. The strip-shaped vents on the freezing conveyor belt, working in conjunction with the internal heaters, ensure that heat is evenly and efficiently transferred to the chicken, preventing it from becoming too stiff or brittle due to excessively low temperatures. Warming the chicken to 0 degrees Celsius maintains its good shape retention while providing moderate firmness, significantly improving the efficiency and precision of subsequent shaping and cutting. This effectively reduces potential debris and irregular breaks during cutting, thus ensuring the appearance quality and processing yield of the chicken products.

[0075] In some embodiments described above in this application, an automatic chicken breast and leg trimming machine is proposed, which includes a transfer component for transferring frozen chicken meat to a chicken trimming and cutting slot. However, in actual operation, the size and shape of the chicken meat may vary. If the transfer component lacks precise positioning and flexible gripping ability, the chicken meat may shift, be damaged, or fail to be accurately placed into the trimming and cutting slot during the transfer process, thereby affecting the efficiency and quality of subsequent trimming and cutting.

[0076] Please continue reading. Figures 1 to 3As shown, this application further proposes that the aforementioned transfer component 6 includes a U-shaped support plate 61. The U-shaped support plate 61 is sleeved on the rear end of the outer side of the refrigeration conveyor belt 3. A first strip groove 62 is provided on both vertical plates of the U-shaped support plate 61. A synchronous motor (not shown) is installed in the first strip groove 62. The output end of the synchronous motor is connected to a first screw 63. A first moving block 64 is spirally sleeved on the first screw 63. A U-shaped plate 65 is provided between the first moving blocks 64 at the left and right ends. A second [unclear] is provided on the lower surface of the horizontal plate of the U-shaped plate 65. A second motor (not shown) is installed in a second groove (not shown). The output end of the second motor is connected to a second screw (not shown). Both ends of the second screw are helically fitted with U-shaped moving blocks 66. A first telescopic cylinder 67 is installed on the lower surface of the U-shaped moving block 66. A first lifting plate 68 is installed at the end of the telescopic rod of the first telescopic cylinder 67. Multiple first vacuum suction cups (not shown) are evenly arranged on the lower surface of the first lifting plate 68. The left half of the second screw has a left-hand thread, and the right half of the second screw has a right-hand thread.

[0077] The U-shaped support plate, serving as the external frame of the transfer component, is typically made of metal, possessing sufficient rigidity and stability to reliably support the internal transmission and gripping mechanisms. A first strip-shaped groove is located on the two vertical plates of the U-shaped support plate, primarily providing precise guidance for the internal transmission mechanism, ensuring that the first moving block driven by the synchronous motor and the first screw can move smoothly and accurately along a preset path. The synchronous motor drives the first screw to rotate, thereby achieving the horizontal movement of the U-shaped plate. It provides precise speed and position control, ensuring that the U-shaped plate accurately moves to the target position during transfer. The first screw is connected to the output end of the synchronous motor, converting the motor's rotational motion into the linear motion of the first moving block, exhibiting high transmission efficiency and positioning accuracy. The first moving block is helically sleeved on the first screw and connected to the U-shaped plate. When the first screw rotates, the first moving block moves along the screw's axis, thereby driving the U-shaped plate to perform horizontal displacement. The U-shaped plate is one of the core actuators of the transfer mechanism. Its lower surface supports components such as the second groove, second motor, second screw, U-shaped moving block, first telescopic cylinder, first lifting plate, and first vacuum suction cup. Its main function is to horizontally grasp and place the chicken. The second groove, located on the lower surface of the U-shaped plate, guides the U-shaped moving block driven by the second motor, ensuring precise lateral adjustment along a preset path. The second motor drives the second screw to rotate, thus achieving lateral adjustment of the U-shaped moving block, requiring a certain level of control precision. The second screw is connected to the output of the second motor, converting the motor's rotational motion into linear motion of the U-shaped moving block. Its key feature is that the left half has a left-hand thread, and the right half has a right-hand thread. This design allows the U-shaped moving blocks at both ends to move inward or outward simultaneously when the screw rotates, thereby achieving synchronous adjustment of the grasping distance. U-shaped moving blocks are spirally sleeved on both ends of the second screw and support the first telescopic cylinder. When the second screw rotates, the U-shaped moving blocks move laterally under its drive, thereby adjusting the distance between them. The first telescopic cylinder is located on the lower surface of the U-shaped moving blocks and is used to drive the first lifting plate to perform vertical lifting movements, featuring fast response and compact structure. The first lifting plate is driven by the end of the telescopic rod of the first telescopic cylinder, and multiple first vacuum suction cups are evenly arranged on its lower surface. Its vertical movement allows the first vacuum suction cups to contact or detach from the chicken surface. The multiple first vacuum suction cups located on the lower surface of the first lifting plate generate negative pressure to adsorb the chicken, ensuring stable and uniform gripping of the chicken. The left half of the second screw has a left-hand thread, and the right half has a right-hand thread. This specially designed screw allows the U-shaped moving blocks on both ends of the spiral sleeve to synchronously move towards the center or separate to the sides when the second motor drives its rotation. This ensures that the gripping mechanism can adjust the gripping width in a centrally symmetrical manner, thereby accurately adapting to chicken of different sizes and ensuring stability during gripping.

[0078] The transfer mechanism of this application achieves precise gripping, horizontal movement, and accurate placement of frozen chicken through a sophisticated mechanical structure and control logic. Specifically, after the frozen conveyor belt transports the chicken to the transfer area, firstly, a second motor drives a second screw with left and right spiral threads to rotate, causing the U-shaped moving blocks at both ends of the screw to move synchronously inward or outward. This adjusts the distance between the first telescopic cylinder, the first lifting plate, and the first vacuum suction cups below, precisely matching the width of the chicken to be gripped. After adjustment, the first telescopic cylinder extends, causing the first lifting plate to descend, allowing multiple first vacuum suction cups to contact and adhere to the chicken. Once the adhesion is stable, the first telescopic cylinder retracts, raising the first lifting plate with the gripped chicken to a safe height. Subsequently, a synchronous motor drives the first screw to rotate, causing the first moving blocks with spiral threads on the first screw and their connected U-shaped plates to move horizontally along the first strip groove, precisely moving the entire mechanism gripping the chicken from above the frozen conveyor belt to above the chicken trimming and cutting groove. Upon reaching the target position, the first telescopic cylinder extends again, precisely placing the chicken meat into the chicken trimming and cutting slot and releasing the vacuum suction. Finally, the first telescopic cylinder retracts, the first lifting plate rises, and the entire transfer unit returns to its initial position, ready for the next transfer. Through this coordinated operation, the transfer unit overcomes the challenges posed by variations in chicken size, ensuring that each piece of chicken is stably and accurately transferred from the frozen conveyor belt to the trimming and cutting slot, greatly improving the automation and precision of trimming and cutting.

[0079] In one specific implementation, the U-shaped support plate of the transfer component can be welded from 5mm thick 304 stainless steel plate to provide good structural strength and corrosion resistance. The first groove can use a high-precision linear guide, such as a ball bearing linear guide, to ensure the smoothness and positioning accuracy of the U-shaped plate during horizontal movement. The synchronous motor can be an AC servo motor with a rated power of 100W, whose output shaft is connected to the first screw via a coupling. The first screw can be a ball screw with a diameter of 16mm and a lead of 5mm, used with corresponding ball nuts as the first moving block. The U-shaped plate can be constructed using lightweight, high-strength aluminum alloy profiles. The second groove can use a small linear guide. The second motor can be a DC stepper motor with a rated power of 30W, whose output shaft is connected to the second screw. The second screw can be a trapezoidal screw with a diameter of 10mm and a lead of 2mm, with left-hand and right-hand threads machined at its left and right ends respectively, used with two trapezoidal nuts as U-shaped moving blocks. The first telescopic cylinder can be a pneumatic telescopic cylinder with a stroke of 50mm and a diameter of 20mm, and its telescopic movement is controlled by a solenoid valve. The first lifting plate can be made of anodized aluminum plate. Multiple first vacuum suction cups can be silicone vacuum suction cups with a diameter of 30mm, with negative pressure provided by a vacuum generator and suction and release controlled by solenoid valves. The entire transfer component's movement can be programmed and controlled by a programmable logic controller (PLC) to achieve linkage with the refrigeration conveyor belt and the shaping and cutting groove, ensuring automation and accuracy of the transfer process.

[0080] Through the above technical solution, the transfer component of this application can achieve precise, stable, and flexible transfer of frozen chicken. Specifically, through the left-right spiral design of the second screw, in conjunction with the second motor and U-shaped moving block, the gripping width can be automatically adjusted according to the different sizes of chicken, ensuring stability during gripping and avoiding weak gripping or damage due to size mismatch. At the same time, the U-shaped plate driven by the synchronous motor and the first screw can accurately move the gripped chicken horizontally above the chicken trimming and cutting groove. Combined with the vertical lifting and suction release functions of the first telescopic cylinder and the first vacuum suction cup, it ensures that the chicken can be accurately placed in the preset position, greatly improving the accuracy and efficiency of chicken placement. This precise transfer mechanism effectively solves the technical problems of large differences in chicken size and easy deviation during transfer, ensuring the smooth progress of subsequent trimming and cutting processes, thereby improving the automation level of the entire trimming machine and the product processing quality.

[0081] In some embodiments described above, a second groove is provided on the lower surface of the cross plate of the U-shaped plate. A second motor is installed within the second groove, and the output end of the second motor is connected to a second screw. U-shaped moving blocks are spirally fitted onto both ends of the second screw. A first telescopic cylinder is installed on the lower surface of the U-shaped moving block, and a first lifting plate is installed at the end of the telescopic rod of the first telescopic cylinder. Multiple first vacuum suction cups are evenly spaced on the lower surface of the first lifting plate as transfer components, used to transfer frozen chicken to the chicken trimming and cutting slot. However, in actual operation, due to differences in the shape and size of the chicken, or slight displacement or rotation during transfer, the position and orientation of the chicken may not be precise enough when it is picked up by the first vacuum suction cup and placed into the chicken trimming and cutting slot, thus affecting the accuracy and efficiency of subsequent trimming and cutting.

[0082] Please continue reading. Figure 1 and Figure 2 As shown, this application further proposes that the front of the U-shaped plate 65 is provided with an L-shaped fixing plate 69, and a detection camera 60 is provided on the L-shaped fixing plate 69.

[0083] The L-shaped fixing plate is a structural component with an L-shaped cross-section, serving as a stable and precise mounting base for the inspection camera. This fixing plate can be implemented in various ways; for example, it can be formed from sheet metal (such as stainless steel) through bending or welding processes and fixed to the front of the cross plate of the U-shaped plate; alternatively, it can be integrated with the cross plate of the U-shaped plate through integral molding to ensure structural strength and positioning accuracy. The inspection camera is a visual sensor device used to capture images or video, monitoring the status of chicken meat in real time during transport or placement. This inspection camera can be an industrial camera, such as a high-resolution CCD or CMOS camera, with a suitable lens and light source to obtain clear images of the chicken meat; or it can be an intelligent visual sensor with integrated image processing capabilities, capable of directly outputting information such as the position and posture of the chicken meat.

[0084] The solution proposed in this application provides a stable mounting position for the detection camera by setting an L-shaped fixing plate on the front of the horizontal plate of the U-shaped plate. When the transfer component picks up the chicken and moves it above the chicken trimming and cutting groove, or after the chicken is placed in the chicken trimming and cutting groove, the detection camera mounted on the L-shaped fixing plate can capture real-time images of the chicken from above or the side. The image data captured by the detection camera can be transmitted to the control system for analysis, thereby accurately identifying the actual position, orientation, and whether the chicken has completely fallen into the chicken trimming and cutting groove. Based on this visual feedback information, the control system can fine-tune the movement of the transfer component, such as adjusting the rotation of the first screw or the second screw, to correct the deviation of the chicken and ensure that the chicken is in the optimal trimming and cutting position before entering the cutting stage. This visual detection and feedback mechanism significantly improves the placement accuracy of the chicken, providing a reliable foundation for subsequent trimming and cutting.

[0085] The following is a concrete example: the L-shaped fixing plate can be made of 3mm thick SUS304 stainless steel sheet and is bolted to the front of the horizontal plate of the U-shaped plate. Its L-shaped structure allows the inspection camera to be mounted approximately 150mm above the chicken trimming and cutting groove, covering the entire area of ​​the groove. The inspection camera can be a 5-megapixel industrial camera, for example, equipped with a 12mm fixed-focus lens and a ring LED light source to ensure clear images of the chicken under various lighting conditions. The inspection camera connects to an industrial computer via an Ethernet interface. The industrial computer runs image processing software that can identify the chicken's outline, calculate its center point coordinates and rotation angle, and send this data in real time to the PLC system controlling the transfer components.

[0086] Through the above technical solution, during the process of transferring chicken to the chicken trimming and cutting slot, the detection camera can acquire real-time image information of the chicken and accurately detect its actual position and posture. If the chicken deviates from the preset position or posture, the control system can immediately adjust the movement of the transfer component based on the detection results, such as fine-tuning the movement distance of the first moving block or the U-shaped moving block, thereby ensuring that the chicken is accurately and stably placed in the chicken trimming and cutting slot. This greatly improves the accuracy and reliability of chicken placement, effectively avoiding cutting errors or product scrap caused by inaccurate chicken positioning, and thus improving the overall trimming and cutting efficiency and yield.

[0087] In some other embodiments, this application proposes an automatic chicken breast and leg trimming machine, which includes a chicken trimming and cutting groove for trimming and cutting the chicken. However, in actual cutting operations, because the surface of the chicken may be slippery or irregular, the chicken is prone to displacement or sliding within the chicken trimming and cutting groove when the cutting blade is in action, thus affecting the cutting accuracy and consistency. Furthermore, if the bottom of the chicken trimming and cutting groove does not provide adequate space for the cutting blade to pass through, the cutting blade may collide with the bottom of the groove after cutting, leading to blade wear or groove damage, thereby affecting the long-term stable operation of the equipment and the cutting effect.

[0088] Please continue reading. Figures 1 to 3 , Figure 5 As shown, this application further proposes that the inner bottom surface of the chicken trimming and cutting groove 54 is provided with a plurality of anti-slip protrusions 55 at equal intervals, and that the inner bottom surface of the chicken trimming and cutting groove 54 is provided with strip-shaped cutting openings (not shown) corresponding to the cutting blades around its perimeter.

[0089] The anti-slip protrusions are raised structures on the bottom surface of the chicken trimming and cutting groove. Their main function is to increase the friction between the chicken and the bottom surface of the groove, effectively securing the chicken during cutting and preventing unnecessary slippage or displacement. These protrusions can be implemented in various forms; for example, they can be designed as a series of regularly arranged conical, hemispherical, or cylindrical protrusions, with their height and spacing optimized to accommodate chicken of different sizes and shapes. Alternatively, the anti-slip protrusions can be achieved by forming a textured surface with a high coefficient of friction on the bottom surface of the groove, such as using a grid, serrated, or dot-matrix structure to provide stronger grip. The strip-shaped cutting slits are narrow openings around the bottom surface of the chicken trimming and cutting groove. Their function is to provide a precise path for the cutting blade, ensuring that the blade can completely penetrate the chicken and complete the cut without interfering with or damaging the body of the chicken trimming and cutting groove. These cutting slits can be customized according to the shape and size of the cutting blade used. For example, if the cutting blade is square, the strip-shaped cutting slits can be designed as rectangular grooves matching the width of the square blade. In addition to simple rectangular slots, strip-shaped cutouts can also be channels with specific guiding functions to guide the cutting blade down accurately.

[0090] This application's solution effectively solves the problems of unstable positioning of chicken and interference between the cutting blade and the groove during the cutting process by setting anti-slip protrusions and strip-shaped cutting openings on the bottom surface of the chicken trimming and cutting groove. When frozen chicken is transferred to the chicken trimming and cutting groove by a transfer device, the chicken is placed on the bottom surface of the groove with anti-slip protrusions. These anti-slip protrusions can form multi-point contact with the chicken surface using their protruding structure, significantly increasing the friction between the chicken and the groove. This allows the chicken to be firmly fixed in the preset cutting position when the cutting blade of the cutting device presses down, preventing the chicken from sliding or shifting due to force and ensuring cutting accuracy. At the same time, strip-shaped cutting openings corresponding to the cutting blade are opened around the bottom surface of the chicken trimming and cutting groove. These cutting openings are precisely matched in position and shape with the cutting blade on the cutting device. When the cutting blade descends to cut, they can smoothly pass through these strip-shaped cutting openings, completely cutting the chicken without touching the bottom or side wall of the chicken trimming and cutting groove. This design not only protects the cutting blades and groove from damage, extending the equipment's lifespan, but also ensures thorough cutting and consistent shaping results. Through the stabilizing effect of the anti-slip protrusions and the precise guidance of the strip-shaped cutting kerf, the entire shaping and cutting process is completed efficiently and accurately, significantly improving the processing quality and production efficiency of chicken products.

[0091] In one specific implementation, the bottom surface of the chicken trimming and cutting groove can be provided with multiple hemispherical anti-slip protrusions made of wear-resistant rubber or polyurethane material at equal intervals. These protrusions are approximately 2-3 mm high and spaced approximately 10-15 mm apart to ensure uniform and sufficient gripping force on the chicken. These anti-slip protrusions can be integrally formed into the bottom of the chicken trimming and cutting groove or fixed by embedding. Simultaneously, strip-shaped cutting openings corresponding to the cutting blade can be formed around the perimeter of the bottom surface of the chicken trimming and cutting groove. For example, if the cutting blade is a square cutting blade approximately 2 mm wide and 50 mm long, the strip-shaped cutting openings can be designed as rectangular grooves slightly wider than 2 mm (e.g., 2.2 mm) and slightly longer than 50 mm (e.g., 52 mm), precisely positioned directly below the downward path of the cutting blade. These cutting openings can be formed at the bottom of the groove using precision milling or laser cutting processes to ensure accuracy in size and position.

[0092] By incorporating anti-slip protrusions on the bottom surface of the chicken trimming and cutting groove, the friction between the chicken and the groove is effectively increased. This securely holds the chicken during cutting, preventing slippage or displacement and significantly improving cutting precision and consistency. Simultaneously, the groove's bottom surface features strip-shaped cutting slits corresponding to the cutting blade, allowing the blade to completely penetrate the chicken and complete the cut without interference. This protects both the blade and the groove, extending the equipment's lifespan and ensuring thorough cutting and consistent trimming results. Therefore, this solution significantly improves the quality and efficiency of chicken trimming and cutting while reducing equipment maintenance costs.

[0093] In some embodiments described above in this application, although a cutting element and a chicken trimming cutting groove are proposed for chicken trimming and cutting, in actual cutting process, the edges of the cut chicken may adhere to the cutting blade, or the cut chicken may not be easily removed from the cutting groove, affecting cutting efficiency and subsequent transfer.

[0094] Please continue reading. Figures 1 to 3 , Figure 6 and Figure 7 In this regard, this application further proposes that the aforementioned cutting component 7 includes a square cutting blade 71, a gantry frame 72 is fitted on the outer middle of the U-shaped support frame 5, and a second telescopic cylinder 73 is embedded at both ends of the horizontal plate of the gantry frame 72. A lifting seat 74 is provided at the end of the telescopic rod of the second telescopic cylinder 73. A blade holder 75 is provided at both ends of the lower surface of the lifting seat 74, and a square cutting blade 71 corresponding to the strip-shaped cutting opening is provided on the lower surface of the blade holder 75. Guide rails 76 are provided on the inner sides of the two vertical plates of the gantry frame 72. The lifting seat 74... The left and right sides are provided with guide rail grooves (not shown) that cooperate with the guide rail 76. The lower surface of the lifting seat 74 is provided with a third telescopic cylinder 77 at both ends. The telescopic rod end of the third telescopic cylinder 77 is provided with a pressing frame 78 for placing the edge that is lifted after cutting. The lower surface of the blade holder 75 is embedded in the middle of a fourth telescopic cylinder (not shown), and the fourth telescopic cylinder is located in the square cutting blade 71. The telescopic rod end of the fourth telescopic cylinder is provided with an ejector block 70. The lower surface of the ejector block 70 is provided with a plurality of ejector protrusions 701 at equal intervals.

[0095] The square cutting blade is a tool with a square or rectangular cross-section used for precise cutting and shaping of chicken. It can be made of materials such as stainless steel, high-carbon steel, or ceramic, and its edges are precision-ground to ensure sharpness. The gantry frame is a support frame with a portal-like structure, typically composed of two vertical plates and one horizontal plate. It supports and guides moving parts and can be constructed from welded or bolted metal profiles, providing sufficient rigidity and stability. The second telescopic cylinder is an actuator that uses compressed air to drive the piston rod to extend and retract, providing linear reciprocating motion. It can be a single-acting or double-acting cylinder, and its extension and retraction are controlled by a pneumatic control valve. The lifting seat is a load-bearing component that can move up and down along a guide rail, used to install and fix the cutting blade and related mechanisms. It can be machined from sheet metal and has guide rail grooves on its sides to mate with the guide rails on the gantry frame. The blade holder is used to fix the square cutting blade, ensuring the blade's stable position during cutting. It can be made of high-strength plastic or metal and the square cutting blade is securely installed on the lower surface of the blade holder using bolts, clamps, or clips. A guide rail is a mechanical component that provides a linear motion trajectory, used to guide moving parts to move precisely in a specific direction. It can be a linear rolling guide rail or a sliding guide rail. A guide rail groove is a recess on the lifting seat that mates with the guide rail, used to allow the lifting seat to slide smoothly along the guide rail. It can be formed on the side of the lifting seat through machining. The third telescopic cylinder is another actuator that uses compressed air to drive the piston rod to extend and retract, used to drive the pressing frame to move up and down. It can be a single-acting or double-acting cylinder, operated through an independent control circuit. The pressing frame is a frame structure with a specific shape and size, used to press the edges of the chicken after cutting to prevent it from being lifted by the cutting blade. It can be made of lightweight materials with a certain degree of rigidity. The fourth telescopic cylinder is a compact cylinder whose size and structure need to adapt to the internal space of the blade. It can be a miniature cylinder or a thin cylinder, achieving rapid extension and retraction through precise pneumatic control. The ejector block is a retractable component with multiple ejector protrusions on its lower surface, used to separate the chicken from the cutting blade after cutting. It can be made of wear-resistant and food-safe materials. The ejector protrusions are protruding structures evenly spaced on the lower surface of the ejector block, which directly contact the chicken meat to achieve the ejection function, and can be integrally formed with the ejector block.

[0096] This application's solution refines the cutting component into a combined structure comprising a square cutting blade, a gantry frame, a second telescopic cylinder, a lifting seat, a blade holder, a guide rail, a guide rail groove, a third telescopic cylinder, a pressing frame, a fourth telescopic cylinder, an ejector block, and an ejector protrusion. This achieves precise cutting of chicken, effective pressing of the cut edges, and reliable ejection of the cut chicken. Specifically, the gantry frame is stably mounted on the outside of the U-shaped support frame. The second telescopic cylinder embedded in its horizontal plate drives the lifting seat to perform precise vertical lifting movements along the guide rail on the inner side of the gantry frame's vertical plate and the guide rail groove on the side of the lifting seat. The blade holder on the lower surface of the lifting seat fixes the square cutting blade, enabling it to accurately align with the strip-shaped cutting opening within the chicken trimming cutting groove for cutting. When the cutting blade completes the cutting and begins its return stroke, the third telescopic cylinder on the lower surface of the lifting seat extends, driving the pressing frame to press the cut edges of the chicken, thereby effectively preventing the chicken edges from being lifted by the cutting blade due to adhesion. Next, the fourth telescopic cylinder embedded in the center of the lower surface of the blade holder extends its ejector block. Multiple ejector protrusions on the lower surface of the ejector block directly act on the cut chicken, forcibly separating it from the square cutting blade and ejecting it. This ensures that the cut chicken remains intact and stable in the chicken trimming cutting groove, preparing it for subsequent transfer. This collaborative working mechanism ensures a smooth cutting process and the integrity of the cut chicken.

[0097] The following is a concrete example: The square cutting blade can be made of food-grade stainless steel, 1mm thick, with laser-cut and finely ground edges. The gantry frame can be constructed from anodized aluminum profiles, with its vertical plates bolted to the outside of the U-shaped support frame, and the horizontal plates reinforced with ribs. The second telescopic cylinder can be a double-acting cylinder with a 50mm stroke, controlled by a solenoid valve for air intake and exhaust. The lifting seat can be made of high-strength engineering plastic, with guide grooves milled on its left and right sides to mate with linear ball bearing guides. The blade holder can be modularly designed, consisting of two detachable polyoxymethylene (POM) pieces, with the square cutting blade clamped and fixed to the lower surface of the blade holder by screws. The guide rails can be two 100mm long miniature linear ball bearing guides, installed on the inner sides of the two vertical plates of the gantry frame. The third telescopic cylinder can be a single-acting cylinder with a 20mm stroke, whose piston rod automatically retracts when there is no air pressure. The pressing frame can be welded from lightweight aluminum alloy profiles, with a food-grade silicone pad adhered to its lower surface. The fourth telescopic cylinder can be an ultra-thin cylinder with a diameter of 10mm and a stroke of 5mm. Its body is embedded inside the blade holder, and the piston rod passes through the pre-drilled hole inside the square cutting blade. The ejector block can be injection molded from food-grade polyethylene material, and its lower surface has four cylindrical ejector protrusions evenly spaced, each protrusion having a diameter of 3mm and a height of 2mm.

[0098] Through the above technical solution, the square cutting blade can accurately cut the chicken during the chicken trimming and cutting process. After cutting, the third telescopic cylinder drives the pressing frame to press down on the edges of the cut chicken in a timely manner, effectively preventing the edges of the chicken from being lifted by the cutting blade due to adhesion. At the same time, the fourth telescopic cylinder drives the ejector block and its ejection protrusion to forcibly separate and eject the cut chicken from the square cutting blade, ensuring that the chicken remains intact in the chicken trimming and cutting groove. This significantly improves cutting efficiency and the integrity of the chicken, avoiding production interruptions or product damage caused by adhesion or difficulty in removal, thus ensuring smooth subsequent transfer and processing.

[0099] In some embodiments described above, an automatic chicken breast and leg trimming machine is proposed, capable of flattening, freezing, and trimming the chicken. However, after the chicken has been trimmed and cut, the key to the smooth operation of the entire automated process lies in how to efficiently, accurately, and without damage transfer the cut chicken from the trimming area to subsequent processing stages. Without a flexible and reliable discharge and transfer mechanism, the cut chicken may accumulate, become misaligned, or be damaged during transfer, thus affecting production efficiency and product quality.

[0100] Please continue reading. Figures 1 to 4 As shown, in some other embodiments, this application proposes an automatic shaping machine for feeding chicken breast and leg meat. A support column 9 is provided on the right rear end of the U-shaped support frame 5. A discharge conveyor belt 91 is mounted on the support column 9. Slide rail grooves 92 are provided on the outer sides of the front and rear support plates of the discharge conveyor belt 91. A multi-section telescopic cylinder 93 is installed in the rear slide rail groove 92. An L-shaped moving block 94 is slidably mounted in the slide rail groove 92. The telescopic rod ends of the multi-section telescopic cylinder 93 are connected to the L-shaped moving block 94. A U-shaped connecting plate 95 is provided between the upper surfaces of the L-shaped moving blocks 94 at both ends. A fixing plate 96 is provided on the left side of the horizontal plate of the U-shaped connecting plate 95. A strip-shaped opening 97 is provided on the fixing plate 96. A third motor (not shown) is provided in the strip-shaped opening 97. The output end of the third motor is connected to a third screw 98. A U-shaped slider 99 is spirally sleeved on the third screw 98. A fifth telescopic cylinder 90 is provided on the lower surface of the U-shaped slider 99. A second lifting plate 901 is provided at the end of the telescopic rod of the fifth telescopic cylinder 90. A plurality of second vacuum suction cups (not shown) are provided on the lower surface of the second lifting plate 901 for transferring the cut chicken to the discharge conveyor belt 91.

[0101] The support columns, serving as the structural foundation, provide stable support for the entire material handling and transfer mechanism. They can be made of solid or hollow metal profiles, such as square or round steel pipes, or a truss structure welded from multiple profiles, ensuring rigidity and stability during equipment operation. The discharge conveyor belt carries and transports the cut chicken pieces. It can be a modular plastic mesh belt, rubber belt, or chain conveyor to adapt to the chicken's transport needs, and its length and width can be adjusted according to the actual production line layout. The slide rails provide precise linear guidance for the L-shaped moving blocks, ensuring stable horizontal movement. They can be in the form of dovetail grooves, T-grooves, or linear guides, and can integrate rolling or sliding bearings to reduce friction. Multi-section telescopic cylinders provide variable stroke linear driving force for adjusting the overall position of the L-shaped moving blocks. They can be multi-stage pneumatic telescopic cylinders or electric push rods to achieve precise stopping at different positions. The L-shaped moving block is the component that supports the U-shaped connecting plate and moves along the slide rail groove. It can be made of aluminum alloy, stainless steel, or high-strength engineering plastics and can be designed with self-lubricating or low-friction surfaces. The U-shaped connecting plate connects the L-shaped moving block and serves as the mounting platform for the subsequent transfer mechanism. It can be a welded or integrally formed U-shaped metal plate structure to provide sufficient strength and rigidity. The fixing plate provides a mounting base for the third motor and defines the range of the strip opening. It can be a metal plate or composite material plate of appropriate thickness. The strip opening allows the third motor or its driven components to move horizontally. It can be a precision-machined long slot or guide hole. The third motor provides rotational power, driving the third screw to achieve the horizontal movement of the U-shaped slider. It can be a stepper motor, servo motor, or DC geared motor to meet positioning accuracy and speed requirements. The third screw converts the rotational motion of the third motor into the linear motion of the U-shaped slider. It can be a trapezoidal screw or ball screw to achieve high-precision and high-efficiency transmission. The U-shaped slider moves along the third screw, carrying the fifth telescopic cylinder and the second lifting plate. It can be a combination of a nut seat and a U-shaped bracket, or a one-piece slider. The fifth telescopic cylinder provides vertical linear drive for raising and lowering the second lifting plate; it can be a small pneumatic cylinder or an electric linear actuator. The second lifting plate supports the second vacuum suction cup and moves vertically with the fifth telescopic cylinder; it can be a flat metal plate or a structure with reinforcing ribs. The second vacuum suction cup uses negative pressure to adsorb and cut the chicken meat, achieving non-destructive gripping and transfer. It can be made of materials such as silicone, rubber, or polyurethane, and the appropriate number and arrangement of suction cups can be selected according to the shape and size of the chicken meat.

[0102] This application's solution provides a dedicated discharge channel for cut chicken by setting a support column on the right rear end of a U-shaped support frame and installing a discharge conveyor belt on the support column. To ensure that the cut chicken can be accurately picked up, the solution designs a transfer mechanism with flexible adjustable position. Specifically, an L-shaped moving block is driven by a multi-section telescopic cylinder to slide within a slide rail groove, allowing the U-shaped connecting plate and its mounted transfer components to adjust their overall horizontal position within a certain range. Furthermore, a strip-shaped opening is provided on the fixing plate of the U-shaped connecting plate, and a third motor drives a third screw to make the U-shaped slider move precisely horizontally within the strip-shaped opening, thereby further accurately adjusting the lateral position of the transfer mechanism. When the transfer mechanism reaches the target position, the fifth telescopic cylinder below the U-shaped slider extends and retracts, causing the second lifting plate to rise and fall vertically, allowing multiple second vacuum suction cups on the lower surface of the second lifting plate to accurately contact and adsorb the cut chicken. After adsorption is complete, the fifth telescopic cylinder retracts, lifting the chicken meat. Then, through the coordinated action of the third motor and multiple telescopic cylinders, the adsorbed chicken meat is moved above the discharge conveyor belt, and the vacuum is released, placing the chicken meat onto the discharge conveyor belt to complete the transfer. The entire process achieves automated, precise, and non-destructive transfer of cut chicken meat.

[0103] The following is a specific example: The support column can be made of 100mm x 100mm square steel tubing, welded and fixed to the U-shaped support frame. The discharge conveyor belt can be a 300mm wide food-grade polyurethane mesh belt, driven by a small geared motor. The slide rail can be two parallel linear guides, each 500mm long, equipped with corresponding sliders. The multi-section telescopic cylinder can be a three-section cylinder with a stroke of 200mm, precisely controlled by a pneumatic control valve. The L-shaped moving block can be machined from 10mm thick aluminum alloy plate, with sliders integrated at its bottom to mate with the linear guides. The U-shaped connecting plate can be bent and welded from 5mm thick stainless steel plate, with a cross section length of 400mm. The fixing plate can be made of 8mm thick aluminum plate, with a 250mm long strip opening. The third motor can be a 50W rated power stepper motor, connected to the third screw via a coupling. The third screw can be a ball screw with a diameter of 12mm and a lead of 5mm. The U-shaped slider can be an aluminum alloy slider with a ball nut, and its bottom is designed with an interface for installing the fifth telescopic cylinder. The fifth telescopic cylinder can be a miniature cylinder with a stroke of 80mm. The second lifting plate can be a perforated aluminum plate with dimensions of 200mm x 150mm. The second vacuum suction cup can be a flat silicone suction cup with a diameter of 20mm, evenly distributed on the lower surface of the second lifting plate, and the suction is provided by a vacuum generator.

[0104] Through the above technical solution, this application provides a highly automated and flexible material handling and transfer mechanism. This mechanism can make multi-dimensional and precise adjustments based on the actual position of the cut chicken, ensuring that the second vacuum suction cup can accurately pick up the cut chicken. This adjustable transfer method effectively avoids missed picking or damage caused by chicken position deviation, significantly improving the success rate and efficiency of transfer. At the same time, using a vacuum suction cup for gripping can protect the integrity and appearance of the chicken to the greatest extent, avoiding squeezing or deformation that may be caused by mechanical clamping. The entire material handling process is automated, reducing manual intervention, thereby improving the overall automation level, hygiene standards, and product consistency of the production line, providing high-quality semi-finished products for subsequent packaging or deep processing stages.

[0105] In some other embodiments, this application proposes an automatic chicken breast and leg meat trimming machine, which processes the chicken through a series of steps including conveying, freezing, trimming, and cutting. However, after the chicken is cut and trimmed, especially the cut edges, there may be issues such as poor discharge, accumulation, or deviation from the predetermined path, affecting subsequent automated processing and reducing the overall operating efficiency of the equipment.

[0106] Please continue reading. Figures 1 to 3 As shown, this application further proposes to provide an inclined guide plate 50 on the rear surface of the cross plate of the U-shaped support frame 5 for guiding the chicken meat out of the cut edge.

[0107] This inclined guide plate is a planar structure with a certain tilt angle. Its main function is to guide the cut edges of the chicken meat in a predetermined direction using gravity or inertia, thus facilitating smooth discharge. The guide plate can be made of materials such as food-grade stainless steel, high-molecular-weight polyethylene (UHMW-PE), or polyoxymethylene (POM) to ensure wear resistance, easy cleaning, and compliance with food hygiene standards. Its surface can be polished to reduce friction and ensure smooth sliding of the chicken meat edges. The tilt angle of the inclined guide plate can be adjusted according to the characteristics of the chicken meat, the cutting speed, and the discharge requirements to optimize the guiding effect. For example, a fixed-angle plate can be used, as can an adjustable-angle hinged structure, or a curved guide surface can be formed using flexible materials.

[0108] This application's solution effectively solves the problem of poor discharge from the edges of cut chicken by installing an inclined guide plate on the rear surface of the horizontal plate of the U-shaped support frame. After the chicken is trimmed by the cutting components, especially the edge parts separated from the main body, due to their irregular shape and potential stickiness, they tend to accumulate or scatter randomly near the cutting area without external guidance. The inclined guide plate is precisely installed on the rear surface of the horizontal plate of the U-shaped support frame, and its inclination angle allows these trimmed edge chicken pieces to slide along the surface of the guide plate under gravity and be guided to the predetermined discharge path. This setup ensures that cutting waste or trimmed edge parts can be discharged from the working area in a timely and orderly manner, avoiding interference with subsequent conveying or processing stages. In this way, the inclined guide plate and the structure of the U-shaped support frame form an efficient waste management mechanism, enabling the entire trimming machine to achieve continuous and stable automated operation, significantly improving the overall processing efficiency and reliability of the equipment.

[0109] In one specific implementation, the inclined guide plate can be a rectangular plate made of food-grade stainless steel. One edge of the plate is fixed to the rear surface of the cross plate of the U-shaped support frame by welding or bolting, while the other edge slopes downwards, forming a fixed inclination angle of approximately 15 to 30 degrees. The surface of the stainless steel plate is finely polished to ensure smoothness and reduce frictional resistance of the chicken edges during sliding. The width of the inclined guide plate can match the width of the chicken trimming and cutting groove to ensure that all cut edges are effectively collected and guided. Furthermore, the lower end of the inclined guide plate can extend above a waste collection container or another waste conveyor belt, thereby achieving automatic collection and transfer of the cut chicken edges.

[0110] By installing an inclined guide plate on the rear surface of the cross plate of the U-shaped support frame, the solution of this application effectively solves the problem of poor material discharge from the edge of the cut chicken after trimming. The inclined guide plate, with its specific inclination angle, provides a smooth sliding channel for the cut chicken edge, allowing it to be automatically and orderly discharged from the cutting area, avoiding accumulation or scattering inside the equipment. This not only ensures the cleanliness and unobstructed flow of the cutting area, preventing equipment blockage or operational interruptions due to waste accumulation, but also significantly improves the automation level and continuous operation capability of the entire automatic trimming machine. Therefore, this solution ensures the stability and efficiency of the chicken trimming and cutting process, reduces the need for manual cleaning and intervention, and thus improves the overall operational reliability and economic benefits of the production line.

[0111] In this invention, the refrigeration unit, multi-section telescopic cylinder, telescopic cylinder, synchronous motor, motor, heater, and detection camera are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0112] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
