A bone sawing machine for broiler processing

Abstract

This invention discloses a bone saw for broiler processing, relating to the field of broiler processing technology. It includes a rotating feeding assembly mounted on top of a conveyor frame. The rotating feeding assembly comprises a first gear, a second gear, multiple displacement plates, and multiple separator rings. The first gear and the second gear are meshed together. The separator rings are movably connected to one side of each of the multiple displacement plates. Through intermittent meshing of the first and second gears, the multiple displacement plates and the multiple separator rings rotate synchronously to push the meat pieces adhering to the conveyor belt surface. By activating a servo motor, the force on the surface of the first spring decreases, gradually restoring it to its initial state, which in turn drives the displacement plates and separator rings to move. After being squeezed, the separator rings continue to rotate under the rotation of an auxiliary shaft. The angle between the separator rings and the displacement plates is also adjustable to avoid rigid connections that would increase the impact force on the meat pieces and damage their quality.

Description

Technical Field

[0001] This invention relates to the field of broiler processing technology, specifically to a bone saw for broiler processing. Background Technology

[0002] Bone saws are mainly used for cutting hard ingredients such as bones, especially in meat processing. They utilize a high-speed rotating saw blade, typically made of metal with sharp serrations, to easily cut through bone. First, a whole chicken or pieces of chicken are placed on the feeding platform of the bone saw, ensuring its stable position. The operator adjusts the cutting height and position of the bone saw according to the desired cutting area and thickness, ensuring the saw blade can precisely cut the target area. The bone saw is then started; the motor begins running, and the saw blade quickly enters working mode and begins cutting. The chicken is conveyed to the cutting mechanism via a conveyor belt, and the bones are gradually pushed forward, allowing the saw blade to cut along the predetermined trajectory. The operator can then remove the cut meat and bones for further processing and packaging. After cutting, the bone saw should be cleaned promptly to remove residual meat and bone fragments and avoid cross-contamination. Regular inspection and replacement of the saw blade are also necessary to ensure the normal operation of the equipment.

[0003] After the broiler chickens are cut by the bone saw, they are conveyed downwards using a conveyor belt. After being cut, the surface of the meat pieces contains free water and sarcoplasmic proteins, forming a water film. This water film is sticky. Since the conveyor belt is mostly made of rubber, which is hydrophilic, it has an affinity for the water film formed by the meat pieces. The two adhere to each other, attracting and locking in the surface moisture of the meat pieces, causing them to stick together. If cracks or scratches appear on the conveyor belt surface, the oil in the meat pieces seeps into the interior and solidifies, forming a rough layer of dirt that sticks to subsequent new pieces of meat. Therefore, the end of the conveyor belt cannot naturally detach the meat pieces by gravity. As the meat pieces accumulate, the power of the bone saw conveyor belt increases, and workers need to repeatedly go near the conveyor belt to remove the sticky meat pieces to prevent the conveyor belt from stopping and delaying the entire processing cycle. Summary of the Invention

[0004] The purpose of this invention is to provide a bone saw for broiler processing, which solves the problem mentioned in the background art that the grease in the meat chunks seeps into their interior and solidifies to form a rough dirt layer that sticks to subsequent new meat chunks. As a result, the end of the conveyor belt cannot naturally detach the meat chunks by gravity, and the accumulation of meat chunks increases the power of the bone saw conveyor belt.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bone saw for broiler processing, comprising; The conveyor frame and conveyor belt are installed inside the conveyor frame and are used to feed and unload the broilers. The material cutting plate, which is set on one side of the conveyor frame, is used for positioning and cutting broilers. A rotating feeding assembly is installed on top of the conveyor frame. The rotating feeding assembly includes a first gear, a second gear, multiple displacement plates, and multiple separator rings. The first gear and the second gear are meshed together. The multiple separator rings are movably connected to one side of the multiple displacement plates. Through the intermittent meshing of the first gear and the second gear, the multiple displacement plates and the multiple separator rings rotate synchronously to push the meat pieces adhering to the surface of the conveyor belt. A rotary scraping assembly is disposed inside a rotary feeding assembly. The rotary scraping assembly includes multiple guide plates and multiple scraping strips. Every two guide plates are used to restrain the sides of the meat block. One end of each of the multiple scraping strips moves when the separator ring moves to treat the dirt remaining on the surface of the conveyor belt.

[0006] Preferably, a transfer frame is provided on the top of the transfer frame, and a support plate is fixedly installed on the top of the transfer frame.

[0007] Preferably, the rotating material feeding assembly further includes a servo motor, a passive rod, and a circumferential rod. The servo motor is disposed on the top of the support plate. One end of the first gear is connected to the output shaft of the servo motor. The rotating material feeding assembly also includes multiple passive plates, multiple embedded strips, multiple first springs, multiple vertical strips, multiple auxiliary plates, and multiple auxiliary shafts. One side of each of the multiple passive plates is fixedly connected to the outer wall of the circumferential rod. The multiple embedded strips are fixedly installed inside the multiple passive plates. The multiple displacement plates are movably sleeved with one end of each of the multiple embedded strips. The movement of the displacement plates drives the separator ring to move slightly.

[0008] Preferably, multiple first springs are respectively wound around the outside of multiple embedded strips for the displacement plate to return to its initial position when it loses pressure. One end of each of the multiple vertical strips is fixed to the top of the multiple displacement plates. One end of each of the multiple auxiliary shafts is fixed to the top of the multiple separating rings. Multiple auxiliary plates are respectively sleeved on one end of the multiple vertical strips and interpenetrate with one end of the auxiliary shafts for adjusting the tilt angle between the displacement plate and the separating rings.

[0009] Preferably, the rotating feeding assembly further includes multiple second springs, multiple abutment plates, multiple straight racks, and multiple third gears. The two ends of the multiple second springs are respectively connected to one side of the separator ring and the displacement plate. The bottom of the multiple abutment plates is respectively connected to the top of the multiple displacement plates. One side of the multiple straight racks is respectively connected to one side of the multiple abutment plates. The multiple straight racks are meshed with the multiple third gears. The movement of the displacement plate drives the straight racks to mesh with the third gears, thereby applying pressure to the separator ring again to adjust its angle.

[0010] Preferably, the rotating feeding assembly further includes multiple reinforcing plates, multiple reinforcing rods, multiple first cams, multiple loading plates, and multiple second cams. One side of each of the multiple reinforcing plates is connected to one side of each of the multiple passive plates, and one end of each of the multiple reinforcing rods is inserted into the bottom of each of the multiple reinforcing plates to support the third gear so that it meshes with the straight rack.

[0011] Preferably, the first cams are connected to the reinforcing rods, and the second cams are connected to the separator rings through the mounting plates. The first cams rotate their protruding parts to apply pressure to the second cams, and the separator rings gradually tilt after being subjected to force, so as to disperse the concentrated stress generated by the meat pieces on the separator rings and keep the meat pieces intact.

[0012] Preferably, the rotary scraping assembly further includes multiple arc-shaped frames, multiple guide rods, and multiple scraping rings. One end of each of the multiple scraping strips is fixedly connected to the bottom of the multiple scraping rings. The multiple guide rods are fixedly installed inside the multiple arc-shaped frames. The multiple guide plates are movably sleeved with one end of each of the multiple guide rods.

[0013] Preferably, the material feed plate is provided with an outer cover, the outer cover is provided with a motor base, the top of the motor base is provided with a motor, and the output shaft of the motor is connected to a motor shaft.

[0014] Preferably, one end of the motor shaft is provided with a blade, one side of the motor base is provided with an adjusting screw, one end of the adjusting screw is provided with a guide rod for through-cutting the broiler, and one side of the motor base is provided with a protective cover to cover the bloodstains when cutting the broiler.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by starting the servo motor, the first gear, which is connected to its output shaft, is driven to rotate. Referring to the accompanying drawings, the number of teeth on the surface of the first gear is less than the number of teeth on the surface of the second gear. The rotation of the first gear drives the rotation of the second gear meshing with it, transmitting force to the driven rod. The driven rod then rotates at the bottom of the support plate. Connected by the circumferential rod, it drives multiple driven plates to rotate synchronously. These multiple driven plates then perform circumferential motion on the surface of the conveyor belt. At this time, the cut meat pieces are transported by the conveyor belt to the positions of multiple separating rings. The separating rings collect the meat pieces, and as they rotate, they exert a pushing force on the collected meat pieces, pushing them to the side of the conveyor belt for easy separation and subsequent unloading. This solves the problem that most conveyor belts are made of rubber, which has certain limitations. Because of its hydrophilic nature, it has an affinity for the water film produced by the meat, and the two will adhere to each other, attracting and locking in the moisture on the surface of the meat, causing it to stick together. After the teeth of the first gear mesh with the teeth on the surface of the second gear, the rotation of the second gear will drive the driven rod and multiple driven plates to rotate. The first gear will only mesh with the teeth on the surface of the second gear after rotating one revolution. Therefore, the two are intermittently meshing and rotating. As the first spring is subjected to force, it is compressed and deformed. The purpose is that after the displacement plate loses the squeezing force, the force on the surface of the first spring will decrease, and it will gradually return to its initial state, thereby driving the displacement plate and the separator ring to move. After being squeezed, the separator ring continues to rotate under the rotation of the auxiliary shaft. The angle between the separator ring and the displacement plate can also be adjusted to avoid a rigid connection that would increase the impact force on the meat and damage its quality.

[0016] In this invention, after the meat chunks are gathered by the separating ring, a backward force is generated, causing the displacement plate to move closer to the circumferential rod. The two second springs compress and deform, and the movement of the displacement plate also causes the abutment plate to move, which in turn moves the connected straight rack. Since the straight rack meshes with the third gear, it also causes the third gear to rotate circumferentially. Referring to the attached diagram, when the straight rack moves to the right, it causes the third gear to rotate clockwise, which in turn causes the first cam to rotate clockwise. During rotation, the first cam gradually contacts the second cam. After contact, the first cam continues to exert a forward thrust on the second cam. With the connection of the mounting plate, the force on the second cam is transmitted to the separating ring, which continues to rotate, increasing the angle between the separating ring and the displacement plate. If the separating ring is rigid, when encountering sticky or large pieces of meat, a "hard-on-hard" contact point will be formed, causing scratches, cuts, and even compression and deformation of the internal tissues of the meat chunks. The tiltable separating ring... When the separator ring encounters resistance, it will make a deflection motion to disperse concentrated stress and maintain the integrity of the meat pieces to the greatest extent. The separator ring is no longer a fixed-angle cutter. When facing small meat scraps, it can effectively move them in place. When facing large and sticky meat pieces, its tilt angle will automatically adjust slightly to increase the contact area and buffer the force. This achieves uniform adaptability from processing minced meat to whole pieces of meat, reducing downtime caused by jamming. Both reduce hard collisions. The movable guide plate can adjust the channel width in real time according to the size of the meat pieces and the flow rate, avoiding congestion and blockage at the edge of the conveyor belt due to excessive material intake or large meat pieces. This ensures continuous and stable operation of the production line, reduces the number of downtime cleaning due to blockage, and improves overall production efficiency. As the separator ring swings, the multiple scrapers installed on the scraper ring will also rub against the surface of the conveyor belt, removing residual meat scraps from the previous batch. Dirt will reduce the friction between the conveyor belt and the drive roller, causing the conveyor belt to slip, the speed to be unstable, and the belt to deviate. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the problem in existing bone saws used in broiler processing where grease from the meat penetrates and solidifies into a rough layer of dirt, trapping new pieces of meat and preventing gravity from detaching them from the conveyor belt, thus increasing the conveyor belt's power consumption as meat accumulates, this invention provides a bone saw for broiler processing. (Refer to...) Figure 1 and Figure 2 As shown: including: The conveyor frame 100 and the conveyor belt 300 are configured inside the conveyor frame 100 for feeding and unloading broilers. Material cutting plate 200 is set on one side of conveyor frame 100 and is used for positioning and cutting broiler chickens. The rotating feeding assembly 1 is disposed on the top of the conveyor frame 100. The rotating feeding assembly 1 includes a first gear 102, a second gear 103, multiple displacement plates 109 and multiple separator rings 113. The first gear 102 and the second gear 103 are meshed and connected. The multiple separator rings 113 are movably connected to one side of the multiple displacement plates 109 respectively. Through the intermittent meshing of the first gear 102 and the second gear 103, the multiple displacement plates 109 and the multiple separator rings 113 rotate synchronously to push the meat pieces adhering to the surface of the conveyor belt 300. The rotating scraping assembly 5 is located inside the rotating feeding assembly 1. The rotating scraping assembly 5 includes multiple guide plates 503 and multiple scraper strips 505. Every two guide plates 503 are used to bind the two sides of the meat block. One end of each of the multiple scraper strips 505 moves when the separating ring 113 moves to treat the dirt remaining on the surface of the conveyor belt 300.

[0021] First, the operator places the broiler chickens on the surface of the conveyor belt 300. The conveyor belt 300 is driven by the transmission system and rotates continuously inside the conveyor frame 100, thereby transporting the broiler chickens to the inside of the material feed plate 200. The broiler chickens are cut by the cutting mechanism, and the cut pieces of meat continue to be transported to one side by the conveyor belt 300. Gradually, they are fed through the rotating feeding assembly 1 and the rotating scraping assembly 5. The material feed plate 200 is equipped with a special high-strength stainless steel band saw blade with fine teeth to reduce bone fragments and meat damage. The saw blade is tensioned on the drive wheel and the driven wheel and moves in a high-speed unidirectional cycle. The broiler chickens are first transported to the material feed plate 200 by the conveyor belt 300, and are cut as the saw blade rotates.

[0022] Preferred, according to Figure 3 As shown, a transfer rack 400 is provided on the top of the transfer rack 100, and a support plate 411 is fixedly installed on the top of the transfer rack 400.

[0023] A feeder frame 400 is fixedly installed on the top of the conveyor frame 100, and a support plate 411 is fixedly installed on the top of the feeder frame 400. The support plate 411 mainly supports the servo motor 101 installed on the rotating feeder assembly 1.

[0024] To address the issue of water film generated after meat cutting sticking to the conveyor belt 300 and failing to detach naturally, a rotating feeding component 1 is installed to apply pressure to the cut meat pieces, causing them to separate from the conveyor belt 300.

[0025] Preferably, the specific working process of the rotating feeding assembly 1 is as follows: Figure 4As shown, the rotating material feeding assembly 1 also includes a servo motor 101, a passive rod 104, and a circumferential rod 105. The servo motor 101 is located on the top of the support plate 411. One end of the first gear 102 is connected to the output shaft of the servo motor 101. The rotating material feeding assembly 1 also includes multiple passive plates 106, multiple embedded strips 107, multiple first springs 108, multiple vertical strips 110, multiple auxiliary plates 111, and multiple auxiliary shafts 112. One side of each of the multiple passive plates 106 is fixedly connected to the outer wall of the circumferential rod 105. The multiple embedded strips 107 are fixedly installed inside the multiple passive plates 106. Multiple displacement plates 109 are movably sleeved with one end of each of the multiple embedded strips 107. The movement of the displacement plates 109 drives the separator ring 113 to move slightly.

[0026] A servo motor 101 is fixedly mounted on the top of the support plate 411. The output shaft of the servo motor 101 is connected to a first gear 102. A passive rod 104 is inserted through the bottom of the support plate 411. A second gear 103 is sleeved on one end of the passive rod 104. A circumferential rod 105 is fixedly mounted on one end of the passive rod 104. Multiple passive plates 106 are fixedly mounted on the outer wall of the circumferential rod 105. An embedded strip 107 is fixedly mounted inside each of the multiple passive plates 106. A displacement plate 109 is movably sleeved on one end of each of the multiple embedded strips 107. A first spring 108 is wound around the outside of each of the multiple embedded strips 107. One end of each is fixed to one side of a plurality of displacement plates 109. A vertical bar 110 is fixedly installed on the top of each of the plurality of displacement plates 109. An auxiliary plate 111 is fixedly sleeved on one end of each of the plurality of vertical bars 110. An auxiliary shaft 112 is rotatably installed on the bottom of each of the plurality of auxiliary plates 111. A separator ring 113 is fixedly installed on one end of each of the plurality of auxiliary shafts 112. The plurality of displacement plates 109 and the plurality of separator rings 113 are respectively connected by two second springs 114. By applying pressure to one side of the separator ring 113, the auxiliary shaft 112 rotates inside the auxiliary plate 111, thereby adjusting the angle between the displacement plate 109 and the separator ring 113.

[0027] By starting the servo motor 101, the first gear 102, which is connected to its output shaft, is first driven to rotate. (Refer to the attached diagram.) Figure 4It is known that the number of teeth on the surface of the first gear 102 is less than the number of teeth on the surface of the second gear 103. When the first gear 102 rotates, it drives the second gear 103, which meshes with it, to rotate, transmitting force to the driven rod 104. The driven rod 104 then rotates at the bottom of the support plate 411. Under the connection of the circumferential rod 105, it drives multiple driven plates 106 to rotate synchronously. The multiple driven plates 106 then perform circumferential motion on the surface of the conveyor belt 300. At this time, the cut meat pieces pass through the conveyor belt 300. The meat is transported to the positions of multiple separating rings 113, where the separating rings 113 collect the meat pieces. As the separating rings 113 rotate, they push the collected meat pieces to the side of the conveyor belt 300, making it easier for them to separate from the conveyor belt 300 for subsequent unloading. This solves the problem that since the conveyor belt 300 is mostly made of rubber, which is hydrophilic, it has an affinity with the water film generated by the meat pieces, causing them to adhere to each other and attract and lock in the moisture on the surface of the meat pieces.

[0028] After the teeth of the first gear 102 mesh with the teeth on the surface of the second gear 103, the rotation of the second gear 103 will drive the driven rod 104 and multiple driven plates 106 to rotate. The first gear 102 will only mesh with the teeth on the surface of the second gear 103 after rotating one revolution. Therefore, the two are intermittent meshing rotations.

[0029] Preferably, the specific working process of the rotating feeding assembly 1 is as follows: Figure 8 As shown, multiple first springs 108 are respectively wound around the outside of multiple embedded strips 107, for the displacement plate 109 to return to its initial position when it loses pressure. One end of multiple vertical strips 110 is fixed to the top of multiple displacement plates 109, and one end of multiple auxiliary shafts 112 is fixed to the top of multiple partition rings 113. Multiple auxiliary plates 111 are respectively sleeved on one end of multiple vertical strips 110 and interpenetrate with one end of auxiliary shafts 112, for adjusting the tilt angle between the displacement plate 109 and the partition rings 113.

[0030] When the separating ring 113 collects the meat pieces, the meat pieces will exert a reaction force on the separating ring 113, which will also be transmitted to the displacement plate 109. (See attached diagram) Figure 6 and attached Figure 8 The displacement plate 109 will move at one end of the insert strip 107. The first spring 108 receives the thrust of the displacement plate 109. As the first spring 108 is subjected to force, it is compressed and deformed. The purpose is that after the displacement plate 109 loses the squeezing force, the force on the surface of the first spring 108 will decrease, and it will gradually return to its initial state. Then, it will drive the displacement plate 109 and the separator ring 113 to move. After being squeezed, the separator ring 113 continues to rotate under the rotation of the auxiliary shaft 112. The angle between the separator ring 113 and the displacement plate 109 can also be adjusted to avoid rigid connection and increase the impact force on the meat, which would damage the meat quality.

[0031] Preferably, the specific working process of the rotating feeding assembly 1 is as follows: Figure 6 and Figure 7 As shown, the rotary feeding assembly 1 also includes multiple second springs 114, multiple abutment plates 115, multiple straight racks 116, and multiple third gears 119. The two ends of the multiple second springs 114 are respectively connected to the partition ring 113 and one side of the displacement plate 109. The bottom of the multiple abutment plates 115 is respectively connected to the top of the multiple displacement plates 109. One side of the multiple straight racks 116 is respectively connected to one side of the multiple abutment plates 115. The multiple straight racks 116 are meshed with the multiple third gears 119. The movement of the displacement plate 109... The straight rack 116 is driven to mesh with the third gear 119, and pressure is applied to the separator ring 113 again to adjust its angle. The rotating material feeding assembly 1 also includes multiple reinforcing plates 117, multiple reinforcing rods 118, multiple first cams 120, multiple loading plates 121 and multiple second cams 122. One side of each of the multiple reinforcing plates 117 is connected to one side of each of the multiple passive plates 106, and one end of each of the multiple reinforcing rods 118 is inserted into the bottom of each of the multiple reinforcing plates 117 to support the third gear 119 so that it meshes with the straight rack 116.

[0032] After the separating ring 113 gathers the meat pieces, it generates a backward force, causing the displacement plate 109 to move closer to the circumferential rod 105. The two second springs 114 compress and deform, and the movement of the displacement plate 109 causes the abutment plate 115 to move, which in turn moves the connected straight rack 116. Since the straight rack 116 meshes with the third gear 119, it also causes the third gear 119 to rotate circumferentially. (See attached diagram.) Figure 8 When the straight rack 116 moves to the right, it causes the third gear 119 to rotate clockwise, which in turn drives the first cam 120 to rotate clockwise. During the rotation, the first cam 120 gradually contacts the second cam 122. After the two contacts, the first cam 120 continues to push the second cam 122 forward. With the connection of the mounting plate 121, the force on the second cam 122 will be transmitted to the separating ring 113. The separating ring 113 continues to rotate, and the angle between it and the displacement plate 109 increases. If the separating ring 113 is rigid, when it encounters sticky or large pieces of meat, it will form a "hard-on-hard" contact point, which will cause the surface of the meat to be scratched, cut, or even the internal tissue to be squeezed and deformed. When the tiltable separating ring 113 encounters resistance, it will produce a knife-yielding action to disperse the concentrated stress and maintain the integrity of the meat to the greatest extent.

[0033] Multiple first cams 120 are connected to multiple reinforcing rods 118 respectively, and multiple second cams 122 are connected to the partition ring 113 through multiple mounting plates 121 respectively. The first cams 120 rotate their protruding parts to apply pressure to the second cams 122, and the partition ring 113 gradually tilts after being subjected to force, in order to disperse the concentrated stress generated by the meat block on the partition ring 113 and keep the meat block intact.

[0034] One side of each of the multiple reinforcing plates 117 is fixedly connected to one side of each of the multiple passive plates 106; the bottom of each of the multiple abutment plates 115 is fixedly connected to the top of each of the multiple displacement plates 109; one side of each of the multiple straight racks 116 is fixedly connected to one side of each of the multiple abutment plates 115; reinforcing rods 118 are interwoven inside each of the multiple reinforcing plates 117; a third gear 119 is fixedly fitted at one end of each of the multiple reinforcing rods 118; a first cam 120 is fixedly installed on one side of each of the multiple reinforcing rods 118; a mounting plate 121 is fixedly installed on one side of each of the multiple partition rings 113; a second cam 122 is fixedly installed inside each of the multiple mounting plates 121; when the straight racks 116 move, they drive the third gear 119, which meshes with them, to rotate; and with the connection of the reinforcing rods 118, the first cam 120 rotates. The rotation of the first cam 120 gradually contacts the second cam 122, thus generating a thrust on the second cam 122. This thrust drives the separator ring 113 to tilt and rotate. The tilting function allows the separator ring 113 to better conform to the surface of the conveyor belt 300 and the contour of the meat piece, smoothly separating the meat piece, rather than inserting it into the bottom of the meat piece like a lever and suddenly prying it up and sending it flying. This ensures that the meat piece can fall smoothly to the next process along a predetermined trajectory. The next process includes packaging. The separator ring 113 is no longer a fixed angle cut. When facing small meat scraps, it can basically maintain its original position and effectively move the meat. When facing large and sticky meat pieces, its tilt angle will automatically be finely adjusted to increase the contact area and buffer the force, thereby achieving uniform adaptability from processing minced meat to whole pieces of meat, reducing downtime caused by jamming, and reducing hard collisions between the two.

[0035] To address the issue of residual dirt on the surface of the conveyor belt 300, a rotating scraping component 5 is installed to scrape away the dirt by rubbing against the conveyor belt 300 during the meat feeding process.

[0036] Preferably, the specific working process of the rotating scraping component 5 is as follows: Figure 5 As shown, the rotating scraping assembly 5 also includes multiple arc-shaped frames 501, multiple guide rods 502 and multiple scraping rings 504. One end of multiple scraping strips 505 is fixedly connected to the bottom of multiple scraping rings 504 respectively. Multiple guide rods 502 are fixedly installed inside multiple arc-shaped frames 501 respectively. Multiple guide plates 503 are movably sleeved with one end of multiple guide rods 502 respectively.

[0037] Two arc-shaped frames 501 are fixedly installed on one side of each of the multiple separating rings 113. Guide rods 502 are fixedly installed inside each of the multiple arc-shaped frames 501. A guide plate 503 is movably fitted onto one end of each of the multiple guide rods 502. Scraper rings 504 are fixedly installed at the bottom of each of the multiple separating rings 113. Multiple scraper strips 505 are fixedly connected to the bottom of each of the multiple scraper rings 504. The guide plates 503 move at one end of each of the guide rods 502. Meat pieces are mainly collected between two guide plates 503. The movable guide plates 503 can be adjusted in real time according to the size of the meat pieces and the flow rate. The channel width prevents congestion and blockage at the edge of the conveyor belt 300 due to excessive material intake or large meat pieces, ensuring continuous and stable operation of the production line, reducing downtime for cleaning due to blockage, and improving overall production efficiency. As the separator ring 113 swings, the multiple scraper blades 505 installed on the scraper ring 504 will also rub against the surface of the conveyor belt 300, which can remove residual meat scraps from the previous batch. Dirt will reduce the friction between the conveyor belt 300 and the drive roller, causing the conveyor belt 300 to slip, have unstable speed, and run off-track. After scraping, the transmission efficiency and conveying accuracy can be guaranteed.

[0038] It should be noted that the scraper 505 is made of polyurethane, which is elastic and flexible and can conform to the surface of the conveyor belt 300.

[0039] Preferred, according to Figure 2 As shown, the material feed plate 200 has an outer cover 211 inside, a motor base 212 inside the outer cover 211, a motor 213 on the top of the motor base 212, a motor shaft 216 connected to the output shaft of the motor 213, a blade 217 at one end of the motor shaft 216, an adjusting screw 214 on one side of the motor base 212, a guide rod 215 at one end of the adjusting screw 214 for through-cutting the broiler, a protective cover 218 on one side of the motor base 212 to cover the bloodstains during broiler cutting, and a sealing cover hinged to one side of the outer cover 211. Opening the sealing cover exposes the material feed plate 200. The guide rod 215 facilitates the insertion of broiler chickens. The motor 213 is fixedly mounted on the top of the motor base 212. One end of the motor shaft 216 is connected to the output shaft of the motor 213. One side of the blade 217 is fixedly connected to the other end of the motor shaft 216. One side of the protective cover 218 is fixedly connected to the top of the motor base 212 and is located on top of the blade 217. Its main function is to block bloodstains generated when the blade 217 cuts the broiler chickens. The adjusting screw 214 is threaded onto one side of the motor base 212 and fixedly connected to one side of the guide rod 215. The position of the guide rod 215 can be adjusted by moving the adjusting screw 214.

[0040] Working Principle: The bone saw is primarily used for cutting hard ingredients such as bones, especially in meat processing. It utilizes a high-speed rotating saw blade, typically made of metal with sharp serrations, to easily cut through bone. First, the whole chicken or pieces of chicken are placed on the feeding platform of the bone saw, ensuring its stable position. The operator adjusts the cutting height and position of the bone saw according to the desired cutting area and thickness, ensuring the saw blade can precisely cut the target area. Once the bone saw is started, the motor begins to run, and the saw blade quickly enters its working state and begins cutting. The chicken is conveyed to the cutting mechanism via a conveyor belt, and the chicken bones are gradually pushed in. The saw blade cuts along a predetermined path, allowing operators to remove the cut meat and bones for further processing and packaging. After cutting, the bone saw should be cleaned promptly to remove residual meat and bone fragments and prevent cross-contamination. Regular inspection and replacement of the saw blade are also necessary to ensure proper equipment operation. After being cut by the bone saw, the broiler chickens are conveyed downwards via a conveyor belt. As the meat is cut, free water and sarcoplasmic proteins seep out, forming a water film. This water film is sticky, and since the conveyor belt is mostly made of rubber, which is hydrophilic, it has an affinity for the water film formed by the meat, causing them to attract each other. The conveyor belt will attract and lock in the surface moisture of the meat pieces, causing them to stick together. This is further exacerbated by cracks and scratches on the conveyor belt surface, allowing the grease in the meat to seep into and solidify, forming a rough layer of dirt that traps new pieces of meat. As a result, the conveyor belt cannot naturally detach the meat pieces by gravity. The accumulation of meat pieces increases the power of the bone saw conveyor belt, requiring operators to repeatedly remove the stuck pieces to prevent the conveyor belt from stalling and delaying the entire processing cycle. First, the operator places the chicken on the surface of the conveyor belt 300. The conveyor belt 300, driven by the transmission system, continuously rotates inside the conveyor frame 100, thus transporting the chicken. Inside the material feed plate 200, the broiler chicken is cut by a cutting mechanism. The cut pieces continue to be conveyed to one side by the conveyor belt 300, and are gradually fed through the rotating feeding assembly 1 and the rotating scraping assembly 5. The material feed plate 200 is equipped with a special high-strength stainless steel band saw blade with fine teeth to reduce bone fragments and meat damage. The saw blade is tensioned on the drive wheel and the driven wheel, and moves in a high-speed unidirectional cycle. The broiler chicken is first conveyed into the material feed plate 200 by the conveyor belt 300. As the saw blade rotates, the broiler chicken is cut. By starting the servo motor 101, the first gear 102, which is connected to its output shaft, is driven to rotate. (Refer to the attached diagram.) Figure 4It is known that the number of teeth on the surface of the first gear 102 is less than the number of teeth on the surface of the second gear 103. After the first gear 102 rotates, it also drives the second gear 103, which meshes with it, to rotate, transmitting force to the driven rod 104. The driven rod 104 rotates at the bottom of the support plate 411. Under the connection of the circumferential rod 105, it drives multiple driven plates 106 to rotate synchronously. The multiple driven plates 106 then perform circumferential motion on the surface of the conveyor belt 300. At this time, the cut meat pieces are transported by the conveyor belt 300 to the positions of multiple separating rings 113. 3. The meat pieces are collected separately. As the separator ring 113 rotates, it pushes the collected meat pieces to the side of the conveyor belt 300, facilitating their subsequent separation from the conveyor belt 300 for unloading. This solves the problem that the conveyor belt 300 is mostly made of rubber, which is hydrophilic and therefore has an affinity with the water film generated by the meat pieces. The two will attract each other, trapping the moisture on the surface of the meat pieces and causing them to stick together. When the separator ring 113 collects the meat pieces, the meat pieces will exert a reaction force on the separator ring 113, which will also be transmitted to the displacement plate 109. (See attached diagram) Figure 6 and attached Figure 8 The displacement plate 109 will move at one end of the embedded strip 107. The first spring 108 receives the thrust of the displacement plate 109. As the first spring 108 is subjected to force, it is compressed and deformed. The purpose is that after the displacement plate 109 loses the compressive force, the force on the surface of the first spring 108 will decrease, and it will gradually return to its initial state. This will then drive the displacement plate 109 and the partition ring 113 to move. After being compressed, the partition ring 113 continues to rotate under the rotation of the auxiliary shaft 112. The angle between the partition ring 113 and the displacement plate 109 also... It is adjustable to avoid rigid connections that would increase the impact force on the meat and damage its quality. After the separating ring 113 gathers the meat, it generates a backward force, causing the displacement plate 109 to move closer to the circumferential rod 105. The two second springs 114 are compressed and deformed. The movement of the displacement plate 109 also causes the abutment plate 115 to move, which in turn causes the connected straight rack 116 to move. Since the straight rack 116 and the third gear 119 are meshed, the third gear 119 is also rotated. (See attached diagram) Figure 8When the straight rack 116 moves to the right, it causes the third gear 119 to rotate clockwise, which in turn drives the first cam 120 to rotate clockwise. During rotation, the first cam 120 gradually contacts the second cam 122. After contact, the first cam 120 continues to push the second cam 122 forward. With the connection of the mounting plate 121, the force on the second cam 122 is transmitted to the separating ring 113, which continues to rotate, increasing the angle between it and the displacement plate 109. If the separating ring 113 is rigid, when it encounters sticky or large pieces of meat, it will form a "hard-on-hard" contact point, which will cause the meat to... When the surface is scratched, cut, or even the internal tissue is squeezed and deformed, the tiltable separator ring 113 will produce a knife-yielding action when encountering resistance, dispersing the concentrated stress and maintaining the integrity of the meat piece to the greatest extent. After the straight rack 116 moves, it will drive the third gear 119, which is meshed with it, to rotate. Under the connection of the reinforcing rod 118, it will drive the first cam 120 to rotate. As the first cam 120 rotates, it will gradually contact the second cam 122, thus generating a thrust on the second cam 122. Through this thrust, the separator ring 113 can be tilted and rotated. The tilting function allows the separator ring 113 to better conform to the conveyor belt. The 300-inch surface and the contour of the meat block advance smoothly, gently separating the meat block rather than inserting it into the bottom of the meat block like a lever to suddenly pry it up and bounce it away. This ensures that the meat block falls smoothly along a predetermined trajectory to the next process, which includes packaging. The separator ring 113 is no longer a fixed-angle cut; when dealing with small meat scraps, it can effectively separate them while maintaining its original position. When dealing with large and sticky meat blocks, its tilt angle will automatically adjust slightly to increase the contact area and buffer the force, thus achieving uniform adaptability from processing minced meat to whole pieces of meat. This reduces downtime caused by jamming, and both reduce hard collisions. The meat block is mainly collected between the two guide plates 503, which are movable. The guide plate 503 can adjust the channel width in real time according to the size of the meat pieces and the flow rate, avoiding congestion and blockage at the edge of the conveyor belt 300 due to excessive material intake or large meat pieces, ensuring continuous and stable operation of the production line, reducing the number of downtime cleanings caused by blockages, and improving overall production efficiency. As the separator ring 113 swings, the multiple scraper strips 505 installed on the scraper ring 504 will also rub against the surface of the conveyor belt 300, which can remove the residual meat scraps from the previous batch. Dirt will reduce the friction between the conveyor belt 300 and the drive roller, causing the conveyor belt 300 to slip, have unstable speed, and run off-track. After scraping, the transmission efficiency and conveying accuracy can be guaranteed.
