Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of poultry processing equipment, and particularly relates to a broiler chicken meat quality flattening machine. BACKGROUND

[0002] In modern poultry processing production, the broiler carcasses (such as chicken breasts, chicken legs, chicken wings, etc.) after slaughtering, feathering and cutting often become curled and uneven due to stress response and muscle contraction. This irregularity in form brings many problems: first, uneven meat pieces have poor appearance in market sales and are difficult to meet the standards of high-end products, reducing economic value; second, in subsequent slicing, marinating, breading and pre-frying processes, uneven thickness of the meat pieces will make it difficult to unify the processing parameters (such as time and temperature), and it is easy to cause some overcooked or overcooked, affecting product quality and food safety; in addition, curled meat pieces occupy more space during shaping and bagging, reducing packaging efficiency, and may need to be manually trimmed due to irregular shape, increasing waste. At present, some enterprises use manual pressing or simple mechanical pressing plates for processing, but these methods have the disadvantages of low efficiency, uneven pressure, high labor intensity, easy cross-contamination and inability to realize continuous production. In particular, during the processing, simple flattening operation is difficult to improve the meat fiber structure, and it is difficult to achieve tenderization effect at the same time; and the lack of online detection function also makes it difficult to judge the flattening effect in real time, and manual secondary inspection is needed; in addition, there is also a lack of automatic solution for sorting and recycling of unqualified products.

Guide openings 36 are provided on the extension blocks 35. A return spring 37 is provided in the guide openings 36. A vibration block 38 is provided at the end of the return spring 37. A connecting rod 39 is connected to the inner side of the vibration block 38. A vibration plate 8 is provided at the end of the connecting rod 39. Mounting grooves (not shown) are provided at both the front and rear ends of the lower surface of the vibration plate 8. A U-shaped plate 81 is embedded in the mounting groove. Multiple tenderizing needles 82 are provided at equal intervals on the lower surface of the cross plate of the U-shaped plate 81. A driving component 9 for driving the vibration plate 8 to vibrate up and down is provided in the upper middle part of the lifting plate 33.

[0021] The conveyor belt refers to the conveyor device used for continuously transporting chicken meat. Specifically, it can be implemented by using a rubber belt or PVC belt body in conjunction with a motor drive structure. In the scheme, it serves as a material transport carrier that connects various processing stations.

[0022] The first flattening mechanism refers to the primary flattening component set at the beginning of the conveyor belt. Specifically, it is implemented by a mechanical structure that adjusts the height of the pressure roller with a screw. In this scheme, it is used to perform preliminary flattening of the curled meat pieces.

[0023] The flattening and tenderizing mechanism refers to a processing component with vibration puncture function. Specifically, it adopts a combination of spring reset structure and motor-driven cam to achieve vertical vibration. In the solution, the tenderizing needle is used to puncture and destroy muscle fiber tissue at high frequency to improve the elasticity of the meat.

[0024] The second flattening mechanism refers to the secondary flattening component located downstream of the flattening and tenderizing mechanism. Specifically, it adopts a screw roller structure symmetrical to the first flattening mechanism and is used in the scheme to perform secondary shaping and flattening on the tenderized meat pieces.

[0025] The testing agency refers to a thickness monitoring device based on visual measurement, specifically using an adjustable camera in conjunction with a transparent observation window structure. In the solution, the thickness data of the meat pieces is detected in real time as a basis for screening qualified products.

[0026] The recycling and diversion conveyor belt refers to the reverse conveying device located below the main conveyor belt. It is specifically implemented using a belt conveyor driven by an independent motor. In this scheme, it is used to recycle meat pieces that do not meet the thickness requirements and re-enter the processing flow.

[0027] Among them, the screening and diversion component refers to the guiding and sorting device set at the end of the conveyor belt. Specifically, it is realized by using an electric flipping guide plate in conjunction with a controller linkage structure. In the scheme, qualified products and reworked products are automatically diverted to different outlets according to the test results.

[0028] The vibrating block refers to the elastic transmission component that connects to the vibrating plate. Specifically, it is implemented using a combination structure of spring and guide rod. In this design, the mechanical vibration generated by the driving component is converted into the vertical reciprocating motion of the vibrating plate.

[0029] Among them, the tenderizing needles refer to densely arranged metal puncture elements, specifically formed by vertically welding stainless steel needles to the bottom of a U-shaped plate. In the solution, the muscle fiber structure is changed through high-frequency puncture to enhance the tenderizing effect.

[0030] The core innovation of this application lies in forming a continuous processing line by arranging multiple flattening mechanisms and vibration tenderizing mechanisms in series, and combining them with an online detection and automatic sorting system to achieve fully automated processing of broiler carcasses from initial flattening and meat tenderizing to finished product sorting, effectively solving the technical defects of low efficiency and unstable quality of traditional manual processing.

[0031] The working process and principle of this application are as follows: A first flattening mechanism, a smoothing and tenderizing mechanism, a second flattening mechanism, and a detection mechanism are sequentially arranged from left to right on the conveyor belt. The first flattening mechanism performs preliminary flattening treatment on the chicken. The smoothing and tenderizing mechanism includes an L-shaped support plate, with a first screw spirally embedded in the horizontal plate of the L-shaped support plate. A lifting plate is located at the end of the first screw. Extension blocks are arranged around the lower surface of the lifting plate, with guide openings on the extension blocks and return springs installed inside the guide openings. A vibration block is located at the end of the return spring, with a connecting rod connected to the inner side of the vibration block, and a vibration plate is located at the end of the connecting rod. Mounting grooves are formed at both ends of the lower surface of the vibration plate, with U-shaped plates embedded in the mounting grooves. Multiple tenderizing needles are evenly spaced on the lower surface of the horizontal plate of the U-shaped plate. A driving component is located in the middle of the lifting plate to drive the vibration plate to vibrate up and down. Through the up-and-down vibration of the vibration plate and the action of the tenderizing needles, the chicken is smoothed and tenderized. The second flattening mechanism performs secondary flattening treatment on the chicken. The detection mechanism detects the thickness of the chicken. A recycling and diversion conveyor belt is installed below the main conveyor belt, and a screening and diversion component is installed at the discharge end of the conveyor belt to divert unqualified products.

[0032] As a preferred embodiment, the solution of this application is implemented as follows: The conveyor belt is made of food-grade conveyor belt material with an anti-stick coating on the surface. Both the first and second flattening mechanisms adopt height-adjustable pressure roller structures. In the flattening and tenderizing mechanism, the L-shaped support plate is made of stainless steel. The first screw is driven by an electric motor and the height of the lifting plate can be adjusted. The extension block is made of wear-resistant nylon material. The return spring is made of stainless steel, which has good elasticity and corrosion resistance. The vibration block and connecting rod are made of lightweight alloy material to reduce inertia during vibration. The vibration plate is made of food-grade silicone material, which has good flexibility and wear resistance. The U-shaped plate is made of stainless steel, and the tenderizing needle is made of food-grade stainless steel, with the needle tip specially treated to improve the tenderizing effect. The driving component adopts a combination of a waterproof motor and a cam mechanism to achieve high-frequency micro-amplitude vibration. The detection mechanism adopts a high-precision laser rangefinder sensor to detect the thickness of the chicken meat in real time. The screening and diversion component adopts a pneumatic diversion gate structure, which is linked with the detection mechanism to quickly divert unqualified products.

[0033] Through the above-described scheme, this application achieves continuous flattening and tenderizing treatment of chicken meat. The dual flattening action of the first and second flattening mechanisms, combined with the vibration tenderizing treatment of the flattening and tenderizing mechanism, effectively improves the surface smoothness and internal fiber structure of the chicken meat. The coordinated use of the detection mechanism and screening / diverting components ensures consistent product quality. This scheme increases the automation level and production efficiency of chicken meat processing, improves product quality, reduces manual operation, and lowers production costs.

[0034] Please continue reading. Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the driving component 9 includes a fixed box 91 with an open lower surface. The fixed box 91 is embedded in the upper middle part of the lifting plate 33. A first motor 92 is embedded in the right side of the fixed box 91. The output end of the first motor 92 is connected to a first rotating shaft 93. A second rotating shaft 94 is connected to the left side of the fixed box 91 via a first bearing. The ends of the first rotating shaft 93 and the second rotating shaft 94 are connected to cams 95 via second bearings. A third rotating shaft 96 is rotatably connected to the cams 95 at both ends via third bearings. A connecting plate 97 is connected to the lower surface of the third rotating shaft 96. A fourth rotating shaft 98 is provided on the lower surface of the connecting plate 97. The fourth rotating shaft 98 is rotatably disposed in a U-shaped block 99 via a fourth bearing. The horizontal plate of the U-shaped block 99 is connected to the vibrating plate 8.

[0035] The fixed housing features a bottom-opening design to accommodate the transmission components, with its bottom forming a closed installation space with the lifting plate. The first motor is bolted to the right side wall of the housing, its output shaft extending horizontally and coaxially connected to the first rotating shaft. The second rotating shaft is mounted on the left side wall of the housing via ball bearings, and cams with the same eccentricity are mounted at the ends of both shafts. The third rotating shaft is connected to the outer edges of the cams at both ends via spherical roller bearings, forming an adjustable eccentric transmission structure. The connecting plate has an I-shaped cross-section to enhance bending strength, and its bottom is hinged to a U-shaped block via a fourth rotating shaft.

[0036] Specifically, when the first motor is powered on, the output shaft drives the first rotating shaft to rotate at a speed of 1200 revolutions per minute. Since the first and second rotating shafts rotate synchronously via a gear set, the cams at both ends generate an eccentric motion with a 180-degree phase difference during rotation. The third rotating shaft, driven by the cams, makes periodic up-and-down displacements, converting the rotational motion into the vertical reciprocating motion of the U-shaped block via a connecting plate. A self-aligning bearing between the fourth rotating shaft and the U-shaped block compensates for assembly errors, ensuring that the vibrating plate vibrates vertically at a frequency of 2400 times per minute with an amplitude of 3-5 mm. This dual-cam drive structure, through its phase difference design, cancels out the horizontal component of the force, concentrating the vibration energy in the vertical direction, effectively improving the consistency of the puncture depth of the rejuvenation needle.

[0037] As a preferred embodiment, the solution of this application is specifically implemented as follows: The driving component includes a fixed housing with an open lower surface. The fixed housing is embedded in the center of the lifting plate. A first motor is embedded in the right side of the fixed housing. The output end of the first motor is connected to a first rotating shaft. A second rotating shaft is connected to the left side of the fixed housing via a first bearing. Cams are connected to the ends of the first and second rotating shafts via second bearings. A third rotating shaft is rotatably connected to the cams at both ends via third bearings. A connecting plate is connected to the lower surface of the third rotating shaft. A fourth rotating shaft is mounted on the lower surface of the connecting plate. The fourth rotating shaft is rotatably mounted inside a U-shaped block via a fourth bearing. The cross plate of the U-shaped block is connected to the vibrating plate.

[0038] Specifically, the mounting box is made of stainless steel and measures 200mm × 150mm × 100mm. The first motor is a servo motor with a rated power of 500W. Both the first and second rotating shafts are made of 45# steel and have a diameter of 20mm. The cam is made of high-strength alloy steel with an outer diameter of 80mm and an eccentricity of 10mm. The third rotating shaft is made of stainless steel and has a diameter of 15mm. The connecting plate is made of aluminum alloy and has a thickness of 5mm. The U-shaped block is made of high-strength engineering plastic with a smooth inner wall to reduce friction.

[0039] Through the above technical solution, this application achieves precise control and stable movement of the vibrating plate. Due to the use of a cam mechanism, the movement trajectory of the vibrating plate can be customized according to the shape of the cam, thus adapting to chicken of different thicknesses and textures. Simultaneously, the use of multi-stage bearings reduces mechanical friction and extends the service life of the equipment. Furthermore, the modular design simplifies maintenance and component replacement, improving equipment reliability and maintenance efficiency.

[0040] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the first flattening mechanism 2 includes a first support frame 21. The first support frame 21 is provided on both the left and right support plates of the conveyor belt 1. The first support frame 21 is installed and fixed on the support plate of the conveyor belt 1 by a first bolt 22. A second screw 23 is spirally embedded in the middle of the upper horizontal plate of the first support frame 21. A first support block 24 is provided at the end of the second screw 23. A first flattening roller 25 is rotatably connected between the first support blocks 24 at the left and right ends via a fifth bearing. A first anti-stick coating (not shown) is provided on the outer surface of the first flattening roller 25.

[0041] The first support frame is fixed to the conveyor belt support plate by the first bolt, realizing a rigid connection between the frame and the conveyor belt; the second screw is embedded in the middle of the frame cross plate, and the first support block is driven to move vertically by rotating the screw, thereby adjusting the height position of the first flattening roller; the fifth bearing is installed between the left and right support blocks to keep the flattening roller free to rotate; the first anti-stick coating covers the surface of the flattening roller to prevent chicken tissue from sticking together.

[0042] Specifically, during operation, the first support frame is first fixed to the support plates on both sides of the conveyor belt using the first bolt, forming a stable installation foundation. When the flattening height needs to be adjusted, the second screw is rotated to move it up and down within the threaded holes of the frame's cross plate, causing the first support block and the flattening roller to move up and down as a whole. The fifth bearing allows the flattening roller to rotate freely during the chicken conveying process, preventing sliding friction with the conveyor belt. During the flattening operation, the first anti-stick coating continuously acts on the roller surface, effectively preventing direct contact between meat fibers and the metal roller surface. This structure ensures the mechanical stability of the equipment during operation through bolt fixing, provides precise control of the pressing gap through the screw adjustment mechanism, and ensures cleanliness and processing efficiency during continuous operation through the anti-stick treatment.

[0043] As a preferred embodiment, the solution of this application is specifically implemented as follows: The first flattening mechanism includes a first support frame. The first support frame is provided on both the left and right support plates of the conveyor belt. The first support frame is fixed to the support plate of the conveyor belt by the first bolt. A second screw is spirally embedded in the middle of the horizontal plate of the first support frame. A first support block is provided at the end of the second screw. A first flattening roller is rotatably connected between the first support blocks at the left and right ends by a fifth bearing. A first anti-stick coating is provided on the outer surface of the first flattening roller.

[0044] Specifically, the first support frame is made of stainless steel and has a rectangular structure. The first bolts are M8 stainless steel bolts, and four bolts are used to secure each first support frame. The second screw is made of 304 stainless steel, with a diameter of 20mm and a pitch of 2mm. The first support block is made of aluminum alloy and has a cuboid structure. The fifth bearing is a deep groove ball bearing, model 6205. The first flattening roller is made of 304 stainless steel, with a diameter of 100mm and a length of 600mm. The first anti-stick coating is made of food-grade polytetrafluoroethylene (PTFE) with a thickness of 0.5mm.

[0045] Through the above technical solution, this application achieves the preliminary flattening treatment of chicken meat. The first flattening mechanism can effectively flatten curled and uneven chicken meat, improving its shape. The height of the first flattening roller can be precisely controlled by adjusting the second screw to accommodate chicken meat of different thicknesses. The use of the first anti-stick coating effectively prevents chicken meat from adhering to the flattening roller, ensuring the continuity of the flattening process and the integrity of the chicken meat surface. In addition, the design of the first flattening mechanism facilitates disassembly and cleaning, which helps maintain the hygiene of the equipment.

[0046] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the second flattening mechanism 4 includes a second support frame 41. The second support frame 41 is provided on both the left and right support plates of the conveyor belt 1. The second support frame 41 is fixed to the support plate of the conveyor belt 1 by a second bolt. A third screw 42 is spirally embedded in the middle of the upper horizontal plate of the second support frame 41. A second support block 43 is provided at the end of the third screw 42. A second flattening roller 44 is rotatably connected between the second support blocks 43 at the left and right ends via a sixth bearing. A second anti-stick coating (not shown) is provided on the outer surface of the second flattening roller 44.

[0047] The second support frame is detachably connected to the conveyor belt support plate via a second bolt, facilitating equipment maintenance and component replacement. A third screw is helically embedded in the middle of the second support frame's cross plate; rotating the third screw drives the second support block to move vertically, thereby adjusting the gap between the second flattening roller and the conveyor belt. A sixth bearing allows the second flattening roller to rotate freely while maintaining radial constraint. The second anti-stick coating is made of polytetrafluoroethylene (PTFE) material covering the surface of the flattening roller, with a coating thickness controlled within the range of 0.2-0.5 mm.

[0048] Specifically, when the meat chunks enter the second flattening area after being processed in the previous step, the operator adjusts the pressing gap of the second flattening roller by rotating the third screw based on the thickness data fed back by the detection mechanism, ensuring that the gap value precisely matches the target thickness requirement. The second flattening roller rotates passively under the drive of the conveyor belt, and its surface has a second anti-stick coating that effectively reduces the adhesion between the meat protein and the metal roller surface. Supported by the sixth bearing, the second flattening roller maintains a uniform linear speed during the pressing process, preventing tearing of the meat surface due to frictional resistance. This structural design integrates precise adjustment of pressure parameters and anti-sticking functions in the flattening process, ensuring that the meat chunks reach the preset thickness standard and maintain surface integrity after the second flattening.

[0049] As a preferred embodiment, the solution of this application is specifically implemented as follows: The second flattening mechanism includes a second support frame. The second support frame is installed on the left and right support plates of the conveyor belt. The second support frame is fixed to the support plate of the conveyor belt by a second bolt. A third screw is spirally embedded in the middle of the upper horizontal plate of the second support frame. A second support block is installed at the end of the third screw. The second flattening roller is rotatably connected between the second support blocks at the left and right ends by a sixth bearing. A second anti-stick coating is provided on the outer surface of the second flattening roller.

[0050] Furthermore, the second support frame is made of stainless steel, offering excellent strength and corrosion resistance. The second bolt is an M8 stainless steel bolt, ensuring a secure connection between the second support frame and the conveyor belt support plate. The third screw is made of 304 stainless steel, with a diameter of 20mm and a pitch of 2mm, facilitating precise adjustment of the second flattening roller's height. The second support block is made of aluminum alloy, offering lightweight yet high strength. The sixth bearing is a sealed deep groove ball bearing, model 6204, capable of withstanding significant radial loads. The second flattening roller is made of food-grade stainless steel, with a diameter of 100mm and a length adapted to the conveyor belt width. The second anti-stick coating is made of food-grade polytetrafluoroethylene, with a thickness of 0.5mm, providing excellent anti-stick properties and wear resistance.

[0051] Therefore, the second flattening mechanism uses an adjustable-height second flattening roller to flatten the chicken meat a second time after it has been treated by the first flattening mechanism and the leveling and tenderizing mechanism, further improving the flatness of the chicken meat. The second anti-stick coating effectively prevents the chicken meat from sticking to the surface of the flattening roller, ensuring the continuity and stability of the flattening effect.

[0052] Through the above technical solution, this application achieves a secondary flattening process for chicken meat, further improving its flatness. The adjustable height of the second flattening roller makes the flattening process more flexible and adaptable to chicken meat of different thicknesses. The application of a second anti-stick coating effectively prevents chicken meat from adhering, improving the stability of the flattening effect and the cleanliness of the equipment. This secondary flattening mechanism design improves the appearance quality of the chicken meat, enhances the product's market competitiveness, and also provides more uniform raw materials for subsequent processing steps, which is conducive to improving processing efficiency and product quality.

[0053] Please continue reading. Figure 1 and Figure 5 As shown, in one embodiment of the present invention, the detection mechanism 5 includes a gantry frame 51. The gantry frame 51 is mounted on the outer side of the left and right support plates of the conveyor belt 1. A strip-shaped opening 52 is provided on both vertical plates of the gantry frame 51. A second motor (not shown) is installed in the strip-shaped opening 52. The output end of the second motor is connected to a fourth screw 53. A moving block 54 is spirally sleeved on the second screw 53. A camera 55 is installed on the inner side of the moving block 54. A controller 56 is installed on the upper surface of the horizontal plate of the gantry frame 51. A detection port 57 corresponding to the camera 55 is provided on both the left and right support plates of the conveyor belt 1. A glass baffle 58 is installed in the detection port 57.

[0054] The gantry frame is constructed from welded steel, with the distance between its two vertical plates greater than the width of the conveyor belt to form a detection channel. A strip-shaped opening extends longitudinally along the vertical plates, covering two-thirds of the conveyor belt width. The fourth screw uses a ball screw structure with an 8mm lead, and a matching nut pair is built into the moving block. The camera uses an industrial-grade CCD sensor with at least 5 megapixels and a frame rate set to 60fps to adapt to the conveyor belt's operating speed. The glass baffle is made of tempered glass, 5mm thick, with an anti-fog coating.

[0055] Specifically, when the second motor drives the fourth screw to rotate, the moving block moves laterally along the strip opening, causing the camera to scan in the width direction of the conveyor belt. When the conveyor belt runs at a speed of 0.5 m / s, the controller controls the two second motors to operate synchronously according to a preset program, causing the moving blocks on both sides to move towards each other at a speed of 0.2 m / s, forming a reciprocating scanning path. During the movement, the camera captures images of the chicken surface at intervals of 0.1 seconds, and the image data is transmitted to the controller in real time for 3D modeling. The glass baffle at the detection port isolates meat scraps from contamination while controlling its flatness error within ±0.05 mm to ensure distortion-free imaging. When the thickness of the chicken exceeds the set threshold, the controller sends a command to the sorting and diverting component to start the sorting process.

[0056] As a preferred embodiment, the solution of this application is specifically implemented as follows: The inspection mechanism includes a gantry frame, which is mounted on the outer sides of the left and right support plates of the conveyor belt. Strip-shaped openings are formed on the two vertical plates of the gantry frame, and a second motor is installed within each opening. The output end of the second motor is connected to a fourth screw, and a moving block is screwed onto the fourth screw. A camera is installed on the inner side of the moving block. A controller is installed on the upper surface of the horizontal plate of the gantry frame. Inspection ports corresponding to the cameras are formed on the left and right support plates of the conveyor belt, and glass baffles are installed within each inspection port.

[0057] The gantry frame is made of stainless steel, with a height of 1.5 meters and a width of 1 meter. The strip opening is 80 centimeters long and 10 centimeters wide. The second motor is a stepper motor with a power of 200 watts. The fourth screw is 90 centimeters long, 2 centimeters in diameter, and has a pitch of 0.5 centimeters. The moving block is made of aluminum alloy, with a length of 15 centimeters, a width of 10 centimeters, and a height of 8 centimeters. The camera is a high-definition industrial camera with a resolution of 1920*1080 pixels. The controller is a PLC programmable controller. The detection port has a diameter of 10 centimeters, and the glass baffle is made of tempered glass with a thickness of 0.5 centimeters.

[0058] Through the above technical solution, this application achieves automated detection of chicken meat thickness. The camera can move up and down under the drive of the second motor and the fourth screw to adapt to detection needs at different heights. A glass baffle prevents chicken meat from contaminating the camera, ensuring detection accuracy. The controller can analyze the chicken meat thickness in real time based on the image data collected by the camera, providing a basis for subsequent screening and sorting. This design improves detection efficiency and accuracy, reduces manual operation, and effectively solves the problems of low efficiency and large errors in traditional manual detection.

[0059] Please continue reading. Figure 1 and Figure 6As shown, in one embodiment of the present invention, the screening and diversion component 7 includes a U-shaped support frame 71. The discharge end of the conveyor belt 1 is fixed to the U-shaped support frame 71 by a third bolt. The middle of the horizontal plate of the U-shaped support frame 71 has a material port (not shown) corresponding to the inlet of the recycling and diversion conveyor belt 6. A first guide discharge plate 72 is rotatably arranged between the two vertical plates of the U-shaped support frame 71 via a fifth rotating shaft at the front end. A second guide discharge plate 73 is rotatably arranged between the two vertical plates of the U-shaped support frame 71 via a sixth rotating shaft at the rear end. The material port is located between the first guide discharge plate 72 and the second guide discharge plate 73. The fifth rotating shaft is driven by a third motor, and the sixth rotating shaft is driven by a fourth motor. Both the third motor and the fourth motor are electrically connected to the controller 56.

[0060] The U-shaped support frame is fixed to the conveyor belt outlet end by a third bolt. The material inlet in the middle of its horizontal plate is aligned with the inlet of the recycling and diversion conveyor belt, ensuring that substandard meat pieces fall accurately into the recycling channel. The first and second guide discharge plates are connected to the vertical plate of the U-shaped support frame via the fifth and sixth rotating shafts, respectively. The rotation angle of the two guide plates is independently controlled by the third and fourth motors, enabling switching of the discharge direction. The material inlet is located between the two guide plates, forming a physical barrier in the diversion channel. The third and fourth motors are connected to the controller signal and trigger corresponding actions after receiving the camera's detection results. For example, when the meat piece thickness is detected as acceptable, the controller only activates the third motor, causing the first guide discharge plate to contact the conveyor belt outlet end, guiding the meat piece into the acceptable product channel; if the thickness is unacceptable, both the third and fourth motors are activated simultaneously, moving the two guide plates away from the conveyor belt outlet end, and the meat piece slides through the second guide discharge plate into the material inlet, entering the recycling and diversion conveyor belt.

[0061] Specifically, when the camera detects that the chicken meat thickness meets the preset standard, the controller sends a signal to the third motor, driving the fifth rotating shaft to rotate the first guide plate downwards until it contacts the discharge end of the conveyor belt. The meat pieces slide along the surface of the first guide plate into the qualified product collection area. If the thickness is not up to standard, the controller simultaneously starts the third and fourth motors. The first guide plate rotates upwards to detach from the conveyor belt, and the second guide plate rotates downwards to form an inclined surface. The meat pieces slide along the second guide plate into the inlet and are sent back to the previous process for reprocessing via the recycling and diversion conveyor belt. The alignment design of the inlet and the recycling channel prevents the meat pieces from scattering, and the independent drive of the two guide plates further ensures the accuracy of the diversion action. By controlling the rotation angle of the guide plates with motors, the sorting process is fully automated, reducing manual intervention and improving sorting efficiency.

[0062] As a preferred embodiment, the solution of this application is specifically implemented as follows: The screening and diversion component includes a U-shaped support frame. The discharge end of the conveyor belt is fixed to the U-shaped support frame by a third bolt. A material inlet corresponding to the inlet of the recycling and diversion conveyor belt is opened in the middle of the horizontal plate of the U-shaped support frame. A first guide discharge plate is set at the front end between the two vertical plates of the U-shaped support frame via a fifth rotating shaft. A second guide discharge plate is set at the rear end between the two vertical plates of the U-shaped support frame via a sixth rotating shaft. The material inlet is set between the first guide discharge plate and the second guide discharge plate. The fifth rotating shaft is driven by a third motor, and the sixth rotating shaft is driven by a fourth motor. Both the third and fourth motors are electrically connected to the controller.

[0063] The U-shaped support frame is made of stainless steel, with a horizontal plate length of 600mm, a width of 400mm, and two vertical plates each 300mm high. The feed inlet size is 200mm × 300mm. The first and second guide discharge plates are both made of food-grade plastic, with a length of 400mm and a width of 300mm. The fifth and sixth rotating shafts are both made of stainless steel, with a diameter of 20mm. The third and fourth motors are both servo motors with a rated power of 100W. The controller is a programmable logic controller (PLC).

[0064] In practical applications, when the chicken meat thickness is detected to be within acceptable limits, the controller activates the third motor, driving the first guide plate to rotate to a position contacting the conveyor belt's discharge end, thus ensuring the normal discharge of the acceptable chicken meat. When the chicken meat thickness is detected to be unacceptable, the controller simultaneously activates the third and fourth motors, causing the first guide plate to rotate away from the conveyor belt's discharge end, while the second guide plate rotates to a position contacting the conveyor belt's discharge end. This guides the unacceptable chicken meat to the discharge port, where it is then collected by the recycling conveyor belt for further flattening.

[0065] Through the above technical solution, this application achieves automatic linkage control between chicken thickness detection results and discharge direction, improving the accuracy and efficiency of screening and diversion. Simultaneously, the adjustable guide discharge plate design increases the equipment's flexibility, enabling it to adapt to the processing needs of chicken with different specifications and quality requirements. Furthermore, the use of a motor-driven system to replace manual operation reduces human error, improving the level of automation in production and the consistency of product quality.

[0066] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the thickness of the chicken meat is detected by a camera. If the detection is qualified, the third motor is turned on, and the first guide discharge plate contacts the discharge end of the conveyor belt to realize the discharge. If the detection is unqualified, the third motor and the fourth motor are turned on, so that the first guide discharge plate is moved away from the discharge end of the conveyor belt, and the material is guided to the feed port by the second guide discharge plate. The material is then recycled by the recycling and diversion conveyor belt and flattened again.

[0067] The camera is electrically connected to the controller to collect real-time thickness data of the chicken meat on the conveyor belt. The third and fourth motors drive the first and second guide discharge plates to rotate via the fifth and sixth rotating shafts, respectively. The feed inlet is located between the first and second guide discharge plates and aligned with the inlet of the recycling and diversion conveyor belt. A glass baffle embedded in the detection port prevents chicken meat scraps from contaminating the camera.

[0068] Specifically, when the chicken is conveyed to the discharge end by the conveyor belt, the camera collects its thickness data through the detection port and transmits it to the controller. If the thickness meets the preset threshold, the controller only sends a start signal to the third motor, driving the fifth rotating shaft to bring the first guide discharge plate into contact with the discharge end of the conveyor belt, allowing the chicken to slide out along the first guide discharge plate. If the thickness does not meet the standard, the controller simultaneously starts the third and fourth motors, and the fifth and sixth rotating shafts respectively drive the first and second guide discharge plates to rotate synchronously, causing the first guide discharge plate to separate from the discharge end of the conveyor belt. The second guide discharge plate forms an inclined guide surface, guiding the chicken to the discharge port and falling into the recycling and diversion conveyor belt, returning to the previous process for reprocessing. During this process, the glass baffle can prevent chicken fragments from splashing onto the camera surface, ensuring detection accuracy.

[0069] As a preferred embodiment, the solution of this application is specifically implemented as follows: The thickness of the chicken meat is detected by a camera. If the thickness passes the inspection, the third motor is activated, bringing one end of the first guide plate into contact with the discharge end of the conveyor belt to discharge the chicken. If the thickness fails the inspection, the third and fourth motors are activated, moving the first guide plate away from the discharge end of the conveyor belt. The material is then guided to the feed inlet by the second guide plate and collected by the recycling and diversion conveyor belt for further flattening.

[0070] Specifically, the camera uses a high-resolution CCD sensor to measure the chicken thickness in real time through image processing algorithms. When the chicken thickness is detected to be within a preset range, the controller sends a signal to the third motor. The third motor drives the fifth shaft to rotate, causing the first guide plate to tilt and align with the conveyor belt's discharge end. The qualified chicken then smoothly slides into the subsequent packaging process.

[0071] When the thickness of the chicken meat exceeds the preset range, the controller simultaneously activates the third and fourth motors. The third motor drives the first guide plate to flip upwards, and the fourth motor drives the second guide plate to tilt downwards. The substandard chicken meat slides down the second guide plate to the inlet and enters the recycling and diversion conveyor belt. The recycled chicken meat is transported back to the starting point of the flattening process for secondary flattening.

[0072] Through the above technical solution, this application achieves automatic detection and sorting of chicken meat thickness. Qualified products directly enter subsequent processes, improving production efficiency. Unqualified products are automatically recycled and reprocessed, avoiding manual screening and rework, reducing labor costs. At the same time, it ensures the consistency of finished products and improves product quality. In addition, the entire process requires no manual intervention, reducing the risk of cross-contamination and contributing to food safety.

[0073] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the conveyor belt 1 is provided with an auxiliary support plate (not shown) to facilitate the flattening of chicken meat.

[0074] The auxiliary support plate is embedded inside the conveyor belt, with its length aligned with the belt's running direction and its width covering the transverse range of the conveyor belt's working area. The auxiliary support plate is made of metal or a polymer composite material, and its surface is bonded to the inner layer of the conveyor belt. The auxiliary support plate is positioned corresponding to the working areas of the first flattening roller, the second flattening roller, and the smoothing and tenderizing mechanism, providing rigid support when pressure is applied by the flattening rollers. The distance between the auxiliary support plate and the outer layer of the conveyor belt is controlled by adjusting bolts to ensure the conveyor belt remains flat under pressure.

[0075] Specifically, when the flattening roller applies vertical pressure to the chicken on the conveyor belt surface, the auxiliary support plate resists the deformation caused by the pressure through its rigid structure, maintaining the flatness of the conveyor belt's working surface. When the vibrating plate of the flattening and tenderizing mechanism performs up-and-down vibration, the auxiliary support plate limits the amplitude range of the conveyor belt, ensuring consistent piercing depth of the tenderizing needles. A ramp transition structure is provided at the junction of the auxiliary support plate and the recycling and diversion conveyor belt to prevent chicken pieces from getting stuck during transfer. An array of drainage holes is formed on the surface of the auxiliary support plate, allowing water to flow through during the washing process while maintaining structural rigidity. By adjusting the installation position of the auxiliary support plate, it can be adapted to the processing requirements of chicken pieces of different thicknesses.

[0076] As a preferred embodiment, the solution of this application is implemented as follows: An auxiliary support plate is provided inside the conveyor belt. The auxiliary support plate is made of stainless steel, and its length matches the internal width of the conveyor belt. The upper surface of the auxiliary support plate is tightly fitted to the inner surface of the conveyor belt and is evenly distributed along the running direction of the conveyor belt. The two ends of the auxiliary support plate are fixedly connected to the left and right support plates of the conveyor belt by support rods. The support rods penetrate vertically through the conveyor belt and are fixed by locking nuts. The width of the auxiliary support plate is two-thirds of the width of the conveyor belt, and the surface is processed with transverse anti-slip textures with a texture depth of 0.5 mm.

[0077] Through the above technical solution, this application enhances the rigidity of the conveyor belt in the flattening mechanism's operating area by installing an auxiliary support plate within the conveyor belt body, preventing uneven stress on the chicken due to conveyor belt deformation under pressure. The auxiliary support plate operates synchronously with the conveyor belt, maintaining a flat contact between the chicken's bottom surface and preventing displacement or wrinkling during flattening. The transverse anti-slip texture further increases the friction between the chicken and the conveyor belt, ensuring the flattening action is effectively transmitted to the meat tissue, thereby improving overall flattening uniformity.

[0078] The motor, conveyor belt, camera, and controller in this invention are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0079] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
