[0019] The antibacterial unit further includes an ultraviolet lamp, which is fixedly connected to the fixing frame.

[0020] The present invention has the following advantages:

[0021] 1. The poultry carcass first passes through the second wing spreading assembly, where the rotating flexible rod contacts the wings to separate them from the carcass. The poultry carcass then passes through the wing spreading space of the first wing spreading assembly, which exerts a force opposite to the direction of the carcass's movement on the retracted wings. This forces the retracted wings outward and sets their shape, facilitating subsequent wing segmentation and improving wing segmentation accuracy.

[0022] 2. The guide mechanism of the wing pre-cutting assembly can clamp and guide the wings of the poultry. The cutting knife can cut the skin and flesh at the connection between the middle and the root of the wing, so that in the subsequent wing cutting process, the skin and flesh at the connection between the middle and the root of the wing are cut as much as possible to the middle of the wing, increasing the weight of the wing. At the same time, the introduction part of the second guide component is bent inward to facilitate the introduction of the poultry wings into the guide mechanism.

[0023] 3. The linkage mechanism of the mid-wing cutting assembly connects the chain on the conveyor line and the mid-wing cutting mechanism, which can synchronously transmit the operating power of the chain on the conveyor line to the mid-wing cutting mechanism, realizing the synchronous operation of the conveyor line and the mid-wing cutting mechanism. In this way, the upper and lower parts of the poultry carcass can move forward synchronously along the conveyor line, which can improve the accuracy of mid-wing cutting.

[0024] 4. The wing root cutting assembly gradually reduces its clamping space along the conveying direction of the poultry carcass. While facilitating the entry of the wing root into the clamping space, it gradually clamps and positions the wing root, improving the cutting accuracy of the wing root. This allows the cutting unit to cut the connection between the wing root and the carcass, thereby improving the quality of the wing root product.

[0025] 5. The breast meat cutting assembly pre-cuts the breast meat, creating an incision. The breast meat unloading assembly then tears the breast meat off along the incision. The presence of the incision reduces the force applied by the breast meat unloading assembly, preventing damage to the breast meat due to excessive force.

[0026] 6. The antibacterial unit sprays salt water onto parts that are in direct contact with poultry carcasses, such as knives, thereby inhibiting the growth of bacteria on the surface of these parts. At the same time, the salt water pre-marinates the poultry meat, reducing bacterial growth on the poultry meat surface, shortening the subsequent marinating time, and improving production efficiency.

[0065] like Figures 1 to 33 As shown, this embodiment provides an automated poultry cutting production line, including: an antibacterial assembly, a wing spreading assembly, a wing mid-cutting assembly, a wing root cutting assembly, a neck cutting assembly, a breast meat cutting assembly, a breast meat unloading assembly, a spine removal assembly, a frame 9, a track 9-1 and a clamping device 9-2, wherein the track 9-1 is fixedly connected to the frame 9, the clamping device 9-2 is connected to the track 9-1 and moves along the track 9-1, the wing spreading assembly, the wing mid-cutting assembly 3, the wing root cutting assembly 4, the neck cutting assembly 5, the breast meat cutting assembly 6, the breast meat unloading assembly 7 and the spine removal assembly 8 are arranged in sequence along the track 9-1, and the antibacterial assembly includes a plurality of antibacterial units, and the antibacterial unit includes a nozzle 12 and a nozzle 13, and the nozzle 12 and the nozzle 13 are fixedly connected and communicated. The nozzle 12 is used to spray salt water to the knives of the wing cutting assembly 3, the wing root cutting assembly 4, the neck cutting assembly 5, the breast meat cutting assembly 6, the breast meat unloading assembly 7 and the spine removal assembly 8.

[0066] The conveyor line includes a track 9-1, a clamping device 9-2, and a chain main motor. The main motor drives the chain to move. The clamping device 9-2 is connected to the chain. The chain drives the clamping device 9-2 along the track 9-1 and passes through each assembly in sequence. It should be noted that the conveyor line is existing technology.

[0067] Based on the above technical solution, the wing spreading assembly includes a first wing spreading assembly 1 and / or a second wing spreading assembly 2. When the wing spreading assembly includes the first wing spreading assembly 1 and the second wing spreading assembly 2, the second wing spreading assembly 2 is located upstream of the first wing spreading assembly 1 in the conveying direction, that is, the clamping device 9-2 carrying the poultry carcass passes through the second wing spreading assembly 2 first, and the second wing spreading assembly 2 plays the role of spreading the wings.

[0068] like Figure 31As shown, the drive assembly 2-3 of the two second wing spreading units is used to drive the wing spreading roller 2-1 to rotate, and the poultry carcass passes through the second wing spreading space along the track 9-1, and the flexible rod 2-2 on the side close to the poultry carcass rotates from top to bottom. The flexible rod 2-2 contacts the wings of the poultry carcass, driving the wings to create a gap between the body and the trunk. Preferably, a plurality of groups of flexible rods 2-2 evenly arranged along a spiral line are fixedly provided on the outside of a wing spreading roller 2-1. Preferably, the diameter of the flexible rod 2-2 at one end away from the wing spreading roller 2-1 continuously decreases, and the top of the flexible rod 2-2 is spherical or has rounded corners. Preferably, the flexible rod 2-2 is made of silicone, and the diameter of the flexible rod 2-2 is large enough so that the flexible rod 2-2 will not bend or deform visibly due to its own weight. Preferably, the drive assembly 2-3 is a motor, and the two wing spreading rollers 2-1 rotate in opposite directions and at the same speed.

[0069] After the poultry carcass is pre-spread by the second wing spreading assembly 2, it enters the first wing spreading assembly 1 for wing spreading, wherein the second wing spreading assembly 2 spreads the wings, and the first wing spreading assembly 1 further spreads and shapes the wings along the already spread gaps.

[0070] like Figures 2 to 5 As shown, the first wing spreading assembly 1 includes two symmetrically arranged wing spreading units 1-1 on a first frame 1-2. A wing spreading space 1-3A is formed between the two symmetrically arranged wing spreading units 1-1 for the passage of poultry carcasses. The poultry carcasses are suspended on the conveyor line with their necks facing downward and their feet facing upward. At this point, the poultry carcasses face forward and their backs backward, and as the conveyor line rotates, they pass through this wing spreading space 1-3A. The wing spreading unit 1-1 includes a first adjustment component 1-30, which adjusts the size of the wing spreading space 3A according to the size of the poultry carcasses passing through, thereby accommodating poultry carcasses of different sizes.

[0071] Figure 2 and Figure 4 The arrow in the figure indicates the conveying direction of the poultry carcass. When the poultry carcass enters the wing spreading space 1-3A along this direction, the wing spreading unit 1-1 blocks the wings of the poultry, allowing the retracted wings to be spread out, facilitating subsequent wing segmentation and improving wing segmentation accuracy. Simultaneously, the first adjustment assembly 1-30 provided on the wing spreading unit 1-1 can change the size of the wing spreading space 1-3A according to the size of the poultry carcass passing through, thereby accommodating the passage of poultry carcasses of different sizes. This allows the wing spreading space 1-3A to adapt to the size of poultry carcasses of different sizes, resulting in a better wing spreading effect.

[0072] like Figures 3 to 5As shown, the wing spreading unit 1-1 includes a first guide portion 1-10 arranged along the conveying direction of the poultry carcass, the first guide portion 1-10 is fixedly connected to one end of the second guide portion 1-20, the other end of the second guide portion 1-20 is connected to the first adjusting component 1-30, and the first adjusting component 1-30 is rotatably arranged on the first frame 1-2.

[0073] like Figure 4 As shown, the first guide portion 1-10 can guide the poultry carcass in the horizontal direction. Specifically, the first guide portion 1-10 includes a first section 1-101, a second section 1-102, and a third section 1-103 that are sequentially connected to each other. The first section 1-101, the second section 1-102, and the third section 1-103 are integrally formed. The extension direction of the second section 1-102 is consistent with the movement direction of the poultry carcass. The first section 1-101 and the third section 1-103 are respectively arranged at an obtuse angle to the second section 1-102, so that the distance between the first guide portions 1-10 gradually decreases and then gradually increases along the movement direction of the poultry carcass. The distance between the two first sections 1-101 gradually decreases, which facilitates the poultry carcass to enter the wing-spreading space 1-3A. At the same time, the gradually decreasing wing-spreading space 1-3A can force the wings of the poultry to spread when approaching the second guide portion 1-20.

[0074] like Figure 3 As shown, the second guide portion 1-20 includes a first guide segment 1-201, a second guide segment 1-202, a third guide segment 1-203 and a fourth guide segment 1-204 which are connected to each other in sequence. The first guide segment 1-201, the second guide segment 1-202, the third guide segment 1-203 and the fourth guide segment 1-204 are formed as one piece. The first guide segment 1-201 is fixedly connected to the second segment 1-102 of the first guide portion 1-10, and the fourth guide segment 1-204 is movably connected to the first adjustment component 1-30. The height of the first guide portion 1-10 can be adjusted according to the size of the poultry carcass, so that the height of the first guide portion 1-10 is adapted to the size of the poultry carcass.

[0075] The extension direction of the second guide segment 202 is perpendicular to the movement direction of the poultry carcass, and the first guide segment 1-201 has a curvature adapted to the size of the poultry wing. Specifically, the curvature of the first guide segment 201 is adapted to the outer dimensions of the wing.

[0076] The distance between the second guide parts 1-20 gradually decreases and then gradually increases from top to bottom to adapt to the size of the upside-down poultry carcass.

[0077] When the wings of a poultry carcass are spread, the poultry carcass enters the wing spreading space 1-3A from the first section 1-101 of the first guide portion 1-10. At this time, the wings of the poultry are located below the first guide portion 1-10. Specifically, the root of the wing is attached to the lower part of the first guide portion 1-10 and is transported forward. As the wing spreading space 1-3A gradually becomes smaller, the wings of the poultry gradually approach the second guide portion 1-20. When the wings of the poultry carcass contact the second guide portion 1-20, the first guide section 1-201 can block the movement of the wings, that is, generate a force on the wings in the opposite direction of the movement of the poultry carcass. At this time, the retracted wings can be stretched toward the back to achieve the purpose of spreading the wings.

[0078] Preferably, if Figure 5 As shown, the first adjustment assembly 1-30 includes a locking sleeve 1-301 connected to the second guide portion 1-20. By adjusting the relative position between the second guide portion 1-20 and the locking sleeve 1-301, the height of the first guide portion 1-10 can be adjusted so that the height of the first guide portion 1-10 is compatible with the size of the poultry carcass. A connecting shaft 1-302 is also provided on the locking sleeve 1-301, and a shaft sleeve 1-303 is mounted on the connecting shaft 1-302. Along the axial direction of the sleeve 1-303, an elongated hole 1-3031 is provided on the sleeve 1-303; a threaded hole 1-3021 is provided on the connecting shaft 1-302, and the threaded hole 1-3021 is adapted to the position of the elongated hole 1-3031. The fastener passes through the elongated hole 1-3031 and is threadedly connected to the threaded hole 1-3021 to fix the sleeve 1-303 and the connecting shaft 1-302. By adjusting the distance between the threaded hole 1-3021 and one end of the elongated hole 1-3031, the distance between the two wing-spreading units 1-1 can be adjusted to adjust the size of the wing-spreading space 1-3A to adapt to poultry carcasses of different sizes.

[0079] The first frame 1-2 is provided with a through hole. A sleeve 1-303 passes through the first frame 1-2 and is rotatably connected to the first frame 1-2. The end of the sleeve 1-303 is fixedly connected to the first end of the connecting portion 304. The second end of the connecting portion 1-304 is provided with an elastic component 1-305. The elastic component 1-305 includes a fastener disposed on the connecting portion 1-304. The fastener may be a bolt or a screw. The fastener passes through a mounting hole in the connecting portion 1-304. One end of the fastener is located between the connecting portion 1-304 and the first frame 1-2, and the fastener abuts the first frame 1-2. A spring is sleeved on the fastener extending from the mounting hole. Under normal operating conditions, the spring is in a compressed state. In this state, the elastic component 1-305 can generate an external force on the wing spreading unit 1-1 in the direction of the wing spreading space 1-3A, so that the first guide portion 1-10 can be closely positioned against the poultry carcass, thereby better guiding the poultry carcass.

[0080] When the size of the poultry carcass becomes larger, when the poultry carcass passes through this wing space 1-3A, the poultry carcass will generate an outward force from the wing space 1-3A on the wing unit 1-1, causing the wing unit 1-1 to rotate with the part where the sleeve 1-303 is connected to the first frame 1-2 as the rotation center. At this time, the first guide part 1-10 moves away from the wing space 1-3A, and the spring is further compressed to adjust the wing space 1-3A, thereby achieving the purpose of adapting to poultry carcasses of different sizes.

[0081] After the poultry carcasses have been spread their wings, they can first be pre-cut by the wing pre-cutting assembly and then enter the wing cutting assembly, or they can directly enter the wing cutting assembly for cutting the wings.

[0082] like Figures 28 to 30 As shown, the wing pre-cutting assembly includes a guide mechanism 20 and a first cutting knife 30. Figure 28 The middle arrow indicates the conveying direction of the poultry carcasses. Preferably, two symmetrically arranged guide mechanisms 20 are included, forming a conveying space between the two guide mechanisms 20 for the poultry carcasses to pass through. Poultry carcasses are typically suspended on the conveyor line with their necks facing downward and their feet facing upward. In this position, the poultry carcasses face forward and their backs backward, passing through this conveying space as the conveyor line rotates.

[0083] Preferably, the guide mechanism 20 includes a first guide assembly 201 with adjustable height and a second guide assembly 202 fixed to the second frame 10. A clamping space for clamping the wing root is formed between the first guide assembly 201 and the second guide assembly 202. The clamping space gradually decreases in size along the conveying direction of the poultry carcass, making it easier for the wing root to enter the clamping space. Preferably, the first guide assembly 201 and the second guide assembly 202 are both guide rods.

[0084] Preferably, if Figure 29 As shown, the wing pre-cutting assembly also includes an adjustment component 40, which is used to adjust the gap between the first guide component 201 and the second guide component 202 to accommodate poultry carcasses of different sizes and specifications, thereby improving the clamping effect of the poultry wings. The adjustment component 40 includes a guide column 401 disposed on the second frame 10. The guide column 401 is adjustable and is provided with a locking block 402. The locking block 402 is mounted on the guide column 401 and fixed by a set screw. The locking block 402 can slide on the guide column 401 to adjust the height of the clamping space to accommodate poultry carcasses of different sizes and specifications. The locking block 402 is adjustably connected to the first guide component 201. Specifically, the locking block 402 is mounted on the first guide component 201, and the first guide component 201 and the locking block 402 are fixed using a set screw.

[0085] Preferably, continue to refer to Figure 29The first guide assembly 201 includes a first guide portion 2010 extending along the conveying direction of the poultry carcass. A second guide portion 2011 is provided at the front end of the first guide portion 2010, a third guide portion 2012 is provided at the rear end, and a fourth guide portion 2013 is provided in the middle. The third guide portion 2012 and the fourth guide portion 2013 are respectively connected to the adjustment assembly 40. A clamping space is formed between the first guide portion 2010 and the second guide assembly 202. Preferably, the second guide portion 2011 is arc-shaped, and its opening direction is consistent with the conveying direction of the poultry carcass to facilitate the poultry carcass to enter the clamping space. The arc-shaped second guide portion 2011 will not puncture the poultry carcass, and can keep the poultry carcass intact.

[0086] The second guide assembly 202 includes an inlet portion 2020 and a clamping portion 2021. The inlet portion 2020 is bent inward to facilitate the introduction of the poultry carcass into the clamping space. The first cutting blade 30 is positioned near the end of the clamping portion 2021. The inlet portion 2020 includes a first inlet section connected to the second frame 10 and a second inlet section connecting the first inlet section and the clamping portion 2021. The first and second inlet sections are bent inward, gradually increasing the conveying space from small to large. Along the conveying direction of the poultry carcass, the inward-bent introduction part 2020 can facilitate the wings of the poultry carcass to enter the clamping space. As the conveying space becomes larger and the clamping space becomes smaller, the connection between the root part of the wing and the middle part of the wing of the poultry is clamped by the first guide component 201 and the second guide component 202. At this time, as the poultry carcass continues to move, the connection between the root part of the wing and the middle part of the wing of the poultry passes through the first cutting knife 30. The first cutting knife 30 is set at an angle. The first cutting knife 30 cuts the skin and flesh at the connection between the root part of the wing and the middle part of the wing of the poultry to form an incision, so that in the subsequent wing cutting process, the skin and flesh at the connection between the wing and the root part can be divided into the wing as much as possible, thereby increasing the weight of the wing.

[0087] like Figures 6 to 11 As shown, the mid-wing cutting assembly 3 includes a mid-wing cutting mechanism 3-1 and a linkage mechanism 3-2. The linkage mechanism 3-2 connects the chain on the conveyor line and the mid-wing cutting mechanism 3-1, synchronously transmitting the operating power of the conveyor chain to the mid-wing cutting mechanism 3-1, achieving synchronized operation of the conveyor line and the mid-wing cutting mechanism 3-1. This allows the upper and lower parts of the poultry carcass to move forward synchronously along the conveyor line, improving the accuracy of the mid-wing cutting.

[0088] like Figures 7 to 10As shown, the wing mid-cutting mechanism 3-1 includes a left wing mid-cutting mechanism 3-11 and a right wing mid-cutting mechanism 3-12, which are sequentially arranged along the poultry carcass conveying line, and a supporting unit 3-13 arranged between the left wing mid-cutting mechanism 3-11 and the right wing mid-cutting mechanism 3-12. The left wing mid-cutting mechanism 3-11 is provided with a left cutting knife 3-111 for cutting the left wing mid-cutting; the right wing mid-cutting mechanism 3-12 is provided with a right cutting knife 3-121 for cutting the right wing mid-cutting. Preferably, the left cutting knife 3-111 and the right cutting knife 3-121 are both long serrated knives.

[0089] The supporting unit 3-13 is used to support the poultry carcasses, and the supporting surface of the supporting unit 3-13 gradually rises along the poultry conveying direction. Figure 7 and 8 The direction of the middle arrow indicates the conveying direction of the poultry carcass. Along the conveying direction, the lower portion of the poultry carcass first contacts the support unit 3-13. As the support surface gradually rises, the poultry carcass is supported by the support unit 3-13. The poultry carcass first passes through the left wing mid-cutting mechanism 3-11 for cutting the left wing mid-cutting. After the left wing mid-cutting is completed, the poultry carcass enters the right wing mid-cutting mechanism 3-12 for cutting the right wing mid-cutting. After the right wing mid-cutting is completed, the poultry carcass continues to move forward along the conveyor line to the next cutting process.

[0090] Continue to refer Figures 7 to 10 The left mid-wing cutting mechanism 3-11 is provided with a left guide plate 3-113, a left pressure plate 3-114, a first transmission mechanism 3-112 and a guide rail 3-16. The left guide plate 3-113 is arranged vertically, and its thickness is adapted to the size of the connection joint between the mid-wing and the wing root of the poultry. When cutting the left mid-wing, the connection joint between the mid-wing and the wing root of the left side is just stuck on the left guide plate 3-113. The left pressure plate 3-114 is arranged above the left guide plate 3-113, and a gap is set with the left guide plate 3-113. The first transmission mechanism 3-112 is arranged below the left guide plate 3-113. The guide rail 3-16 is arranged on both sides of the first transmission mechanism 3-112, and its extension direction is the same as the poultry conveying direction. The left cutting knife 3-111 extends along the conveying direction of the poultry carcass. The left cutting knife 3-111 is arranged on the left guide plate 113. Preferably, the first transmission mechanism 3-112 is a chain transmission mechanism, and a plurality of guide assemblies 3-15 are provided on the first transmission mechanism 3-112. The first transmission mechanism 3-112 can drive the guide assemblies 3-15 to perform circular motion along the transmission direction of the chain.

[0091] like Figure 10As shown, the guide assembly 3-15 includes a first guide portion 3-151 and second guide portions 3-152 disposed on both sides of the first guide portion 3-151. The first guide portion 3-151 is provided with guide grooves 3-153. When the guide assembly 3-15 moves upward along with the first transmission mechanism 3-112, the guide grooves 3-153 open upward. At this time, the left guide plate 3-113 is disposed in the guide grooves 3-153, and the guide assembly 3-15 can move along the left guide plate 3-113.

[0092] The right mid-wing cutting mechanism 3-12 is provided with a right guide plate 3-123, a right pressure plate 3-124, a second transmission mechanism 3-122 and a guide rail 3-16. The right guide plate 3-123 is vertically arranged, and its thickness is adapted to the size of the joint connecting the mid-wing and the wing root of the poultry. When cutting the right mid-wing, the joint connecting the mid-wing and the wing root of the right side is just stuck on the right guide plate 3-123. The right pressure plate 3-124 is arranged above the right guide plate 3-123, and a gap is set between the right guide plate 3-123. The second transmission mechanism 3-122 is arranged below the right guide plate 3-123. The guide rail 3-16 is arranged on both sides of the second transmission mechanism 3-122, and its extension direction is the same as the poultry conveying direction. The right cutting knife 3-121 extends along the conveying direction of the poultry carcass. The right cutting knife 3-121 is arranged on the right guide plate 3-123. Preferably, the second transmission mechanism 3-122 is a chain transmission mechanism, and a plurality of guide assemblies 3-15 are provided on the second transmission mechanism 3-122. The second transmission mechanism 3-122 can drive the guide assemblies 3-15 to perform circular motion along the transmission direction of the chain.

[0093] In one embodiment, the mid-wing cutting mechanism 3-1 further includes a right guide rod 3-14, which is disposed on the opposite side of the left mid-wing cutting mechanism 3-11. When cutting the left mid-wing, the right guide rod 3-14 can guide the movement of the right wing portion to facilitate the right wing portion to enter the right mid-wing cutting mechanism 3-12.

[0094] like Figure 11 Shown and referenced Figure 7 The linkage mechanism 3-2 includes a large sprocket 3-20 that meshes with the chain on the conveyor line. The large sprocket 3-20 is in transmission connection with a first transmission assembly 3-21 provided on the frame. The first transmission assembly 3-21 can be a chain transmission assembly. The first transmission assembly 3-21 is in transmission connection with a second transmission assembly 3-22, and the second transmission assembly 3-22 is in transmission connection with a second transmission mechanism 3-122. In this way, the power from the conveyor line can be transmitted to the cutting mechanism, so that the first transmission mechanism 3-112 and the second transmission mechanism 3-122 of the cutting mechanism move synchronously with the conveyor line.

[0095] When the poultry carcass enters the wing cutting assembly 3, the supporting unit 3-13 supports the carcass of the poultry, and the left wing of the poultry enters between the left guide plate 3-113 and the left pressure plate 3-114. The connection joint between the wing and the wing root is stuck on the left guide plate 3-113. At this time, the first guide part 3-151 of the guide assembly 3-15 is close to the side of the supporting unit 3-13, which can generate a force on the wing root of the poultry in the opposite direction of the poultry conveying direction, so that the wings of the poultry are unfolded in the direction opposite to the conveying direction. When the poultry moves to the left cutting knife 3-111, the left cutting knife 3-111 cuts the connection between the left wing and the wing root joint, which can improve the cutting accuracy of the wing. After that, the poultry carcass enters the right wing cutting mechanism 3-12 to cut the right wing.

[0096] It should be noted that, according to the requirements of the product, a wing tip cutting device of the prior art can be installed before the wing mid-cutting assembly 3. Afterwards, the poultry carcass enters the wing root cutting assembly 4 along the conveyor line.

[0097] like Figures 12 to 14 As shown, the wing root cutting assembly 4 includes a guide unit 60, a cutting unit 70 and a support unit 80 arranged on a third frame 50. For example, in order to simultaneously cut the wing root parts of the poultry located on both sides of the carcass, the device includes a symmetrically arranged guide unit 60, a cutting unit 70 and a support unit 80, and a conveying space for the poultry carcass to pass through is formed between the two guide units 60. Figure 3 The direction of the arrow in the figure indicates the conveying direction of the poultry carcass. When cutting the wing root, the poultry carcass is usually hung on the conveyor line with the neck facing down and the feet facing up. At this time, the chest of the poultry carcass faces forward and the back faces backward, and it passes through this device as the conveyor line runs to achieve cutting of the wing root.

[0098] Along the conveying direction of the poultry carcass, the cutting unit 70 is arranged downstream of the conveying direction, and the support unit 80 is arranged below the guide unit 60. The extension direction of the support unit 80 is the same as the conveying direction of the poultry carcass. The support surface of the support unit 80 gradually changes from low to high, and the support surface is arranged at an angle. The support unit 80 is used to support the back of the poultry carcass. The inclined support surface can make the poultry carcass cut at an inclined angle at the wing root, which can improve the cutting accuracy and cutting quality of the wing root.

[0099] In one embodiment, the guide unit 60 includes a third guide portion 601, a fourth guide portion 602, and a fifth guide portion 603, arranged sequentially from top to bottom. A clamping space for clamping the wing root is formed between the fourth guide portion 602 and the fifth guide portion 603. The clamping space gradually decreases in size along the conveying direction of the poultry carcass. The larger clamping space at the initial end facilitates the entry of the poultry wing root into the clamping space. At the same time, as the clamping space gradually decreases, the wing root is gradually clamped and positioned, thereby improving the cutting accuracy of the poultry wing root. This allows the cutting unit 70 to cut the joint connecting the wing root and the carcass, thereby improving the quality of the wing root product.

[0100] In one embodiment, Figure 13 As shown, the third guide portion 601 is used to guide the transportation of poultry carcasses to reduce the swing of the poultry carcasses during transportation and prevent low wing root cutting accuracy. The third guide portion 601 includes a fifth guide segment 6010 extending along the direction of conveying the poultry carcasses, a sixth guide segment 6011 disposed at the front end of the fifth guide segment 6010, and a seventh guide segment 6012 disposed in the middle of the fifth guide segment 6010. The fifth guide segment 6010 and the sixth guide segment 6011 are integrally formed. The seventh guide segment 6012 is adjustably connected to the third frame 50 to adjust the distance between the two third guide segments 601 to accommodate poultry carcasses of different sizes. Specifically, the seventh guide segment 6012 is provided with an external thread and is fixed to the third frame 50 using a fastener. The position of the third guide portion 601 can be adjusted by adjusting the distance between the fastener and the end of the seventh guide segment 6012.

[0101] Preferably, the sixth guide segment 6011 is arc-shaped, and its opening direction is consistent with the conveying direction of the poultry carcass, so as to provide space for conveying the poultry carcass. At the same time, the arc-shaped sixth guide segment 6011 is not easy to puncture the poultry carcass, and can maintain the integrity of the poultry carcass.

[0102] In one embodiment, Figure 13 and 14 As shown, the fourth guide portion 602 and the fifth guide portion 603 are adjustably connected to the third frame 50 to change the size of the conveying space to accommodate poultry carcasses of different sizes. The fourth guide portion 602 and the fifth guide portion 603 are adjustable connected to the third frame 50 in the same manner as the third guide portion 601 is adjustable connected to the third frame 50.

[0103] Continue to refer Figure 13 and 14The fifth guide portion 603 includes an inwardly bent introduction section 6030 and a clamping section 6031 extending along the conveying direction of the poultry carcass. The introduction section 6030 and the clamping section 6031 are integrally formed. The inwardly bent introduction section 6030 causes the conveying space to gradually increase from small to large along the conveying direction of the poultry carcass. When the poultry carcass enters the conveying space of the introduction section 6030, the inwardly bent introduction section 6030 can facilitate the wing root portion of the poultry carcass to enter the clamping space. As the poultry carcass is conveyed forward, the conveying space gradually increases, causing the wing root portion of the poultry to be pulled outward, causing the wing root portion to unfold. At this time, the clamping space becomes smaller, and the fourth guide portion 602 and the fifth guide portion 603 clamp and position the wing root portion, so that the cutting unit 70 can accurately cut the wing root portion. The initial end of the fourth guide portion 602 is bent upward, so that the clamping space of the introduction portion becomes larger, making it easier for the wing root portion of the poultry to be introduced into the clamping space.

[0104] In one embodiment, the cutting unit 70 includes a drive unit 702 and a second cutting blade 701 in transmission connection with the drive unit 702. Exemplarily, the drive unit 702 is a motor, the output end of which is in transmission connection with the second cutting blade 701, for driving the rotation of the second cutting blade 701. The second cutting blade 701 is positioned downstream of the fourth guide portion 602 and the fifth guide portion 603. When the poultry carcass is conveyed along the conveyor line to the second cutting blade 701, the high-speed rotating second cutting blade 701 can cut off the wing root portion.

[0105] Preferably, the second cutting knife 701 is a disc knife, and the second cutting knife 701 is set at a preset angle to the conveying direction of the poultry carcass. Before cutting, the setting angle of the second cutting knife 701 is first adjusted according to the size of the poultry carcass so as to accurately cut the wing root part.

[0106] After the wings of the poultry carcasses are cut off along the conveyor line, the poultry carcasses enter the neck cutting assembly 5.

[0107] like Figures 15 to 17As shown, the neck cutting assembly 5 includes a second guide unit 5-20, a second cutting unit 5-40 and a stretching unit 5-30. The second guide unit 5-20 is arranged above the stretching unit 5-30, and the second cutting unit 5-40 is arranged between the second guide unit 5-20 and the stretching unit 5-30. When cutting the neck of a poultry, the poultry carcass is usually hung on the conveyor line with the neck facing downward and the feet facing upward. At this time, the chest of the poultry carcass faces forward and the back faces backward. As the poultry carcass moves, the poultry neck enters between the second guide unit 5-20. The second guide unit 5-20 can guide the movement direction of the poultry neck to prevent the poultry neck from deviating and facilitate the poultry neck to enter the stretching unit 5-30, so that the poultry neck is clamped by the stretching unit 5-30 and the poultry neck is continuously stretched as the poultry carcass is continuously conveyed forward.

[0108] Among them, the second guide unit 5-20 includes a guide plate 5-201, a second adjustment component 5-202 for fixing the guide plate 5-201 and adjusting the tilt angle of the guide plate 5-201, and a second guide groove 5-2010 is provided on the guide plate 5-201.

[0109] like Figure 16 As shown, the arrow direction in the figure is the poultry conveying direction. Along the poultry conveying direction, the width of the second guide groove 5-2010 first gradually decreases, and when it reaches the preset size, the preset size is maintained unchanged. Specifically, the preset size is compatible with the circumferential size of the poultry neck and is slightly larger than the circumferential size of the poultry neck. The second guide groove 5-2010 at the entry end is large in size, which facilitates the poultry necks conveyed along the conveyor line to enter the second guide groove 5-2010. After the poultry neck enters the second guide groove 5-2010, the poultry neck is located in the second guide groove 5-2010 and below the second guide groove 5-2010, and the rest of the poultry carcass is located above the second guide groove 5-2010.

[0110] In one embodiment, along the poultry conveying direction, the guide plate 5-201 includes a first section and a second section, and the first section is bent downward to allow the poultry neck to enter the second guide groove 5-2010. The guide plate 5-201 is arranged at an angle, and along the poultry conveying direction, the guide plate 5-201 gradually moves away from the stretching unit 5-30. That is, after the poultry neck enters the second guide groove 5-2010, the end of the poultry neck is clamped by the stretching unit 5-30. As the conveyor line conveys forward, the guide plate 5-201 continuously tilts upward, causing the guide plate 5-201 to move away from the stretching unit 5-30. At this time, the top surface of the guide plate 5-201 will support the poultry carcass, thereby continuously stretching the poultry neck, keeping the poultry neck in a taut state, and accurately positioning the connection position between the poultry neck and the spine, so that the second cutting unit 5-40 can accurately cut the poultry neck.

[0111] In one embodiment, Figures 15 to 17 As shown, the second guide unit 5-20 includes a first adjustment rod disposed on the fourth frame 5-10, a locking sleeve disposed at the top of the first adjustment rod, a second adjustment rod disposed on the locking sleeve, and the extended end of the second adjustment rod connected to the guide plate 5-201. The first adjustment rod is adjustably connected to the fourth frame 5-10. Specifically, the bottom of the first adjustment rod is provided with an external thread that can be threadedly connected to the fourth frame 5-10. To facilitate securing the first adjustment rod, a nut is also provided on the first adjustment rod, and the nut is fixedly connected to the fourth frame 5-10. The axial directions of the second adjustment rod and the first adjustment rod are perpendicular to each other. Therefore, by adjusting the vertical distance between the top of the first adjustment rod and the fourth frame 5-10, the distance between the guide plate 5-201 and the fourth frame 5-10 can be adjusted, and the inclination angle of the guide plate 5-201 can be adjusted to accommodate poultry of different sizes and specifications, and to accurately cut the necks of poultry of different sizes and specifications.

[0112] The stretching unit 5-30 includes two symmetrically arranged chain assemblies 5-301, which are arranged horizontally. A clamping space for accommodating the poultry neck is formed between the two chain assemblies 5-301. The first drive unit 5-302 simultaneously drives the two chain assemblies 5-301 to rotate through a gear assembly to achieve synchronous operation of the two chain assemblies 5-301. At this time, no relative movement occurs between the poultry neck and the chain assemblies 5-301, and the poultry neck has a good clamping effect, which can reduce the damage caused to the poultry neck by the stretching unit 5-300 and ensure that the poultry neck maintains good quality after being cut. The chain assemblies 5-301 on both sides are clamped, and no relative movement occurs between the poultry neck and the chain assemblies 5-301. The poultry neck has a good clamping effect. When the second cutting unit 5-40 cuts, the poultry neck is fully stretched, and the cutting position can be accurately located, improving cutting accuracy. Preferably, the first drive unit 5-302 can be a motor.

[0113] Along the poultry conveying direction, the second cutting unit 5-40 is arranged downstream of the conveying direction. The second cutting unit 5-40 includes a second drive unit and a disc knife connected to the second drive unit. The second drive unit can drive the disc knife to rotate to cut the poultry necks. Preferably, the second drive unit is a motor. The disc knife is arranged at an angle, and the inclination angle of the disc knife is the same as the inclination angle of the guide plate 5-201, so as to accurately cut the poultry necks. Preferably, the rotating surface of the disc knife is parallel to the guide plate 5-201, and the disc knife is arranged close to the bottom surface of the guide plate 5-201 to facilitate cutting off more poultry necks and prevent the poultry necks from remaining on the poultry carcasses.

[0114] The neck cutting assembly 5 of the present application includes two symmetrically arranged chain assemblies 5-301. The two chain assemblies 5-301 operate synchronously, which can reduce the damage caused to the poultry neck by the stretching unit 5-30, so that the poultry neck maintains good quality after being cut; at the same time, the poultry neck is fully stretched, and when the second cutting unit 5-40 is cutting, the cutting position can be accurately located, thereby improving the cutting accuracy.

[0115] The poultry carcass then enters the breast meat cutting assembly 6, which pre-cuts the breast meat, ie, does not completely separate the breast meat from the poultry carcass.

[0116] Before the brisket is removed from a poultry carcass, the wings and neck have already been removed. At this point, the carcass has two openings: a first opening located between the legs in the lower abdomen, and a second opening located at the junction of the neck and spine. Prior to the brisket and spine removal, the carcass is typically hung on a conveyor line with the second opening facing downward and the feet facing upward. At this point, the carcass' chest faces forward, its back faces backward, and the first opening is positioned forward at a downward angle.

[0117] like Figures 18 to 20 As shown, the breast meat cutting assembly 6 includes a first guide mechanism 6-1, a first cutting mechanism 6-3, a pressing unit 6-4, and a second supporting unit 6-5, which are arranged on the fifth frame 6-0. Along the conveying direction of the poultry carcass, the first cutting mechanism 6-3 is arranged downstream of the first guide mechanism 6-1, the pressing unit 6-4 and the second supporting unit 6-5 are arranged in the middle of the first guide mechanism 6-1, and the pressing unit 6-4 is located above the second supporting unit 6-5. When the poultry carcass runs to the front end of the breast meat cutting assembly 6 along the conveying direction, the second supporting unit 6-5 supports the bottom of the poultry carcass, allowing the poultry carcass to enter the conveying space in a forward-leaning posture. At this time, the first opening is basically located in the vertical direction, which can facilitate the pressing unit 6-4 to enter the interior of the poultry carcass through the first opening. As the poultry carcass is continuously conveyed forward, the pressing unit 6-4 will pass through the second opening, and then the pressing unit 6-4 will generate a downward pressing force on the large breast part of the poultry carcass to position the large breast of the poultry carcass and prevent the large breast part from being offset when being cut.

[0118] In one embodiment, the first guide mechanism 6-1 includes symmetrically arranged first guide plates 6-11, with a central portion of the first guide mechanism 6-1 defining a conveying space for the poultry carcasses. Along the conveying direction of the poultry carcasses, the first guide plates 6-11 include a third guide segment, a fourth guide segment, and a fifth guide segment connected in sequence. The fifth guide segment extends horizontally, and the third and fourth guide segments each bend downward, resulting in a gradually rising upper surface of the first guide plates 6-11 to facilitate the passage of the poultry carcasses into the conveying space.

[0119] The first guide mechanism 6-1 also includes a third adjustment component 6-12, which is used to adjust the height of the first guide plate 6-11 and the width of the conveying space to accommodate poultry carcasses of different sizes and achieve better cutting effects.

[0120] like Figure 18 As shown, the first cutting mechanism 6-3 includes first cutting units symmetrically arranged on either side of the conveying space. The first cutting units include a first disc blade 6-31 and a third drive unit 6-32 for rotating the first disc blade 6-31. The third drive unit 6-32 can be a motor. To thoroughly and conveniently cut the breast of the poultry, the pressing unit 6-4 is provided with an elongated hole extending along the conveying direction of the poultry carcass. The edges of the two disc blades are respectively accommodated in the elongated holes.

[0121] Continue to refer Figure 18 The second supporting unit 6-5 is arranged in the conveying space. The second supporting unit 6-5 includes supporting parts that are symmetrical and arranged at an obtuse angle. A concave supporting space is formed between the two supporting parts for supporting the poultry carcasses. Along the conveying direction of the poultry carcasses, the supporting part includes a first supporting segment 6-51, a second supporting segment 6-52, and a third supporting segment 6-53 that are connected in sequence. The third supporting segment 6-53 extends in the horizontal direction. The end of the third supporting segment 6-53 extends to the bottom of the first cutting mechanism 6-3. The first supporting segment 6-51 and the second supporting segment 6-52 are bent downward respectively. The supporting space gradually increases from low to high to facilitate supporting the bottom of the poultry carcass. At the same time, the poultry carcass can enter the conveying space in a forward-leaning posture.

[0122] like Figure 20 As shown, along the conveying direction of the poultry carcass, the pressing unit 6-4 includes a first pressing part 6-41, a second pressing part 6-42 and a third pressing part 6-43 connected in sequence, the third pressing part 6-43 extends in the horizontal direction and is arranged between the two disc knives, and the second pressing part 6-42 is bent upward to facilitate the pressing part to enter the interior of the poultry carcass from the first opening.

[0123] After the breast meat is cut by the breast meat cutting assembly 6, the poultry carcass enters the breast meat unloading assembly 7, which completely tears off the breast meat.

[0124] like Figures 21 to 24As shown, the breast meat unloading assembly 7 includes a fourth drive unit 7-20 and a breast meat unloading unit 7-30; the fourth drive unit 7-20 is arranged on the sixth frame 7-10 and is transmission-connected to the breast meat unloading unit 7-30, and is used to drive the breast meat unloading unit 7-30 to rotate; the direction of the arrow in the figure is the conveying direction of the breast cover portion, and the breast meat unloading unit 7-30 is used to guide the breast meat on the breast cover portion conveyed by the conveyor line into the breast meat unloading unit 7-30, and tear off the breast meat as the breast meat unloading unit 7-30 rotates, so that the breast meat is separated from the breast cover, and the breast meat will eventually fall into a preset container below. After the breast meat is unloaded from the breast cover portion, the remaining breast cover will continue to be conveyed forward to the next process. The use of this poultry breast meat unloading device replaces manual labor, and the breast meat can be quickly unloaded from the breast cover portion, with high work efficiency, cleanliness, and no pollution.

[0125] The breast meat unloading unit 7-30 includes a first rotating assembly 7-301, a second rotating assembly 7-302, a baffle plate 7-303, and a third guide assembly 7-304. The third guide assembly 7-304 is arranged on one side of the second rotating assembly 7-302. The extension direction of the third guide assembly 7-304 is arranged at an acute angle to the conveying direction of the breast cover part, which can facilitate the breast meat conveyed along the conveyor line to enter the third guide assembly 7-304. The third guide assembly 7-304 includes guide units that are symmetrical and spaced apart from each other, and a guide space is formed between the two guide units. The guide unit includes a guide plate and a guide rod arranged at the end of the guide plate. The guide rod is arranged at an angle, and the guide space gradually becomes smaller in the direction away from the conveyor line, so as to facilitate the breast meat conveyed along the conveyor line to enter between the two guide units.

[0126] The second rotating assembly 7-302 is provided on one side of the first rotating assembly 7-301. The second rotating assembly 7-302 may be a roller. An entrance for introducing the breast meat is formed between the first rotating assembly 7-301 and the second rotating assembly 7-302. The fourth driving unit 7-20 drives the second rotating assembly 7-302 and the first rotating assembly 7-301 to rotate simultaneously, so that the first rotating unit rotates in a clockwise direction and the second rotating unit rotates in a counterclockwise direction, which can facilitate the breast meat to enter the entrance. For example, Figure 24As shown, the fourth drive unit 7-20 includes a drive unit 7-201 and a driving gear 7-202 connected to the drive unit 7-201. The drive unit 7-201 can be a motor. The driving gear 7-202 is meshed with the first passive gear 7-203, and the first passive gear 7-203 is meshed with the second passive gear 204. The first passive gear 7-203 drives the first rotating assembly 7-301 to rotate, and the second passive gear 204 drives the second rotating assembly 7-302 to rotate. The breast meat entering the guide space is clamped by the joint rotation of the first rotating assembly 7-301 and the second rotating assembly 7-302, so that the breast meat enters the entrance. As the first rotating assembly 7-301 rotates, the breast meat is removed from the breast cover and enters between the baffle plate 7-303 and the first rotating assembly 7-301.

[0127] like Figure 23 Shown and referenced Figure 24 The first rotating assembly 7-301 includes breast meat unloading plates 7-3011 arranged around the circumference of the rotating shaft. The breast meat unloading plates 7-3011 are arranged on a central sleeve, a rotating shaft is arranged inside the central sleeve, and a first passive gear 7-203 is arranged on the top of the rotating shaft. Since the breast meat is usually thicker in the middle part, the breast meat unloading plates 7-3011 are provided with a V-shaped groove 7-3012 with an opening away from the rotating shaft. The V-shaped groove 7-3012 is provided in the middle part of the breast meat unloading plates 7-3011, which can conveniently accommodate the thicker breast meat in the middle part. Preferably, twelve breast meat unloading plates 7-3011 are provided on the first rotating assembly 7-301. The twelve breast meat unloading plates 7-3011 are arranged at a preset inclination angle with respect to the rotation center of the rotating shaft, and each breast meat unloading plate 7-3011 forms a rotation direction opposite to the rotation direction of the first rotating assembly 7-301.

[0128] A gap is provided between the baffle plate 7-303 and the first rotating assembly 7-301. This gap is adapted to the thickness of the breast meat, and gradually increases from a small size as it approaches the second rotating assembly 7-302. When the breast meat enters between the baffle plate 7-303 and the first rotating assembly 7-301 from the entrance, the unloaded breast meat is clamped in the gap. As the first rotating assembly 7-301 rotates, it enters the larger gap. At this point, the breast meat will separate from the first rotating assembly 7-301 and fall into a pre-set container below.

[0129] The working process of the breast meat unloading assembly 7 is as follows: when the breast cover of the poultry is transported to the cutting station along the conveyor line, the breast meat enters the guide space and is clamped by the first rotating component 7-301 and the second rotating component 7-302, so that the breast meat enters between the first rotating component 7-301 and the baffle 7-303, thereby unloading the breast meat from the breast cover. The unloaded breast meat moves to the end of the baffle 7-303 with the movement of the first rotating component 7-301, and falls into the container below the breast meat unloading assembly 7. The continuously rotating first rotating component 7-301 can continuously unload the breast meat transported from the conveyor line, and the working efficiency is high.

[0130] After the breast meat has been removed, the poultry carcass enters the spine removal assembly 8.

[0131] like Figures 25 to 27 As shown, the spine removal assembly 8 includes a second guide mechanism 8-1 and a second cutting mechanism 8-2 disposed on the seventh frame 8-0. The second cutting mechanism 8-2 is disposed downstream of the second guide mechanism 8-1. The second cutting mechanism 8-2 includes two symmetrically arranged second cutting units, each of which includes a second disc and a second drive unit for rotating the second disc. The second drive unit can be a motor.

[0132] The second guide mechanism 8-1 includes symmetrically arranged second guide plates 8-11, with a central portion of the second guide mechanism 8-1 defining a conveying space for the poultry carcasses to pass through. The second guide mechanism 8-1 also includes a fourth adjustment assembly that adjusts the distance between the two second guide plates 8-11 to accommodate poultry carcasses of varying sizes.

[0133] In order to facilitate the introduction of poultry carcasses into the conveying space, along the conveying direction of the poultry carcasses, the second guide plate 8-11 includes a first section, a second section and a third section connected in sequence, the third section extends in the horizontal direction, and the second section and the first section are bent downward.

[0134] After removing the spine, the clamping device 9-2 unloads or transfers the remaining part of the poultry carcass (including parts such as chicken legs) to other cutting lines. Finally, the empty clamping device 9-2 clamps the new poultry carcass and continues the circular motion to enter the wing assembly.

[0135] like Figure 32 and 33 As shown, each antibacterial assembly includes two antibacterial units, and the two antibacterial units of the same antibacterial assembly are located on both sides of the knife; among them, the parts of the wing-spreading assembly and other assemblies that are in direct contact with the poultry carcass (such as guide rods, supporting units and other mechanisms) can also be provided with antibacterial assemblies for antibacterial purposes.

[0136] The antibacterial unit also includes a fixing frame 11 and a three-way solenoid valve 14. The outlet of the three-way solenoid valve 14 is fixedly connected and communicated with the nozzle 13. The three-way solenoid valve 14 and / or the nozzle 13 are fixedly connected to the fixing frame 11. The two inlets of the three-way solenoid valve 14 are respectively communicated with brine and water; the brine and water are respectively stored in corresponding water tanks and pumped out to the nozzle 12 by a water pump.

[0137] The antibacterial unit further comprises an ultraviolet lamp 15 , which is fixedly connected to the fixing frame 11 . The ultraviolet lamp 15 irradiates the knife and / or the part in direct contact with the poultry carcass to kill and inhibit the growth of bacteria.

[0138] like Figure 32 As shown, when the antibacterial assembly is used in conjunction with the rotating knife, the nozzle 12 sprays toward the side of the knife away from the poultry carcass, so that the knife can also work normally when the nozzle 12 is cut. Figure 33 As shown, when the antibacterial assembly is used in conjunction with a fixed knife or a part that is in direct contact with a poultry carcass, the spray head 12 sprays in the gap between the two poultry carcasses.

[0139] Salt water and pure water are sprayed alternately through nozzle 12. The salt water pressure is lower than that of the pure water. The pure water is used to rinse away residual meat and grease from components such as knives, and to flush out excess salt to prevent salt (sodium chloride) crystallization. It should be noted that this alternation not only includes equal spraying of salt water and pure water, but also allows for salt water to be sprayed more frequently than pure water, such as five sprays of salt water and one spray of pure water, and so on. The salt water is a low-pressure spray, covering a large area of ​​the knives to inhibit and kill bacteria; the pure water is a high-pressure water column, used to rinse the knives. Preferably, the salt water concentration is 5-12%. If vinegar and / or protease are required for subsequent pickling operations in the factory, a small amount of vinegar and / or protease can be added to the brine. When vinegar and protease are used together, a neutral or slightly acidic protease, such as papain, should be used. The use of acetic acid can adjust the pH of the brine, thereby optimizing the protease's pH and enhancing its activity.

[0140] After the poultry meat comes into contact with the brine, the brine acts as a cure for the meat, saving time in subsequent processing. If subsequent curing is not required, only pure water is used for regular rinsing.

[0141] The present invention has been described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
