Description

Technical Field

[0001] This utility model relates to the field of poultry slaughtering production line technology, specifically to a hanging device for a poultry slaughtering production line. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] During poultry slaughtering and processing, poultry need to be defecate. For fine down feathers, this is usually done through waxing and dewaxing. To prevent wax from entering the poultry's nasal cavity or other respiratory tracts and causing contamination, current methods typically involve hanging the poultry by their legs on racks, with their heads down, before entering the waxing line. Before waxing, the poultry's head is manually turned to a higher position, so that the poultry is in a position where the neck is bent and the torso is horizontal, maintaining this position on the rack for immersion in the wax. During waxing, the poultry's head is kept above the surface of the wax. While this method solves the problem of wax contamination, it is labor-intensive, requiring multiple workers for each waxing line.

[0004] Some existing technologies attempt to solve the above problems through automation. For example, the automatic duck head hanging device, wax-impregnation conveying system, and method proposed in existing technology CN104286133 involve setting an arc-shaped guide rail, higher than the surface of the wax tank, in the parallel direction of the production line. During wax impregnation, the poultry's head on the hanger is inserted into the guide rail. As the hanger descends, it enters the wax tank, and the poultry's torso, neck, and legs are immersed in the wax. The guide rail keeps the poultry's head above the surface of the wax, thus avoiding wax contamination. This method has two problems:

[0005] The guide rail can only lift the poultry's head during the waxing process. After the waxing, the head returns to a plumb position. The not-fully-solidified wax may flow back into the respiratory tract of the head under the influence of gravity, posing a potential risk of contamination.

[0006] Poultry heads vary in size, and some poultry with smaller heads may not fit well in the guide rails and may fall out during the waxing process, thus entering the wax solution and causing contamination. Utility Model Content

[0007] In order to solve the technical problems existing in the background art, the present invention provides a hanging device for poultry slaughtering production line. The poultry slaughtering production line operates synchronously, imitating the way of manually turning the poultry head. The poultry head is pushed into the hanging frame by the upward action of the hook, so that the poultry head is in the high position of the hanging frame, and is held on the hanging frame in a state of neck bending and body horizontal, and then immersed in wax liquid.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This utility model provides a head-hanging device for a poultry slaughtering line, including a main shaft arranged vertically, a sprocket connected to the upper space of the main shaft, and multiple hangers arranged circumferentially on the sprocket for suspending poultry; a moving plate connected to the lower space of the main shaft, and multiple head-pushing mechanisms arranged circumferentially on the moving plate, each head-pushing mechanism corresponding to a hanger in a vertical position, and each head-pushing mechanism having a hook that is rotatably connected to the moving plate; the sprocket and the moving plate rotate to a set position under the drive of the main shaft, the hook rotates, and flips the poultry head, which is in a suspended state below the hanger, onto the hanger, so that the poultry head is at the highest point of the hanger, forming a state of neck bending and body transverse.

[0010] Furthermore, the hook is fixedly connected to the fixed plate, and the fixed plate is rotatably connected to the moving plate via a rotating shaft.

[0011] Furthermore, the sprocket and the moving disc rotate synchronously under the drive of the main shaft.

[0012] Furthermore, the hooks are powered by a cam mechanism to perform the flipping motion. The cam mechanism includes a disc positioned in the space below the hooks. The outer edge of the disc has a groove, and the grooves form a non-circular trajectory. Each hook has a corresponding roller inside the groove, and the rollers are movably connected to the moving disc via a connector.

[0013] Furthermore, the roller is located at the bottom of the connector.

[0014] Furthermore, the connector is movably connected to one end of the connecting rod.

[0015] Furthermore, the other end of the linkage is movably connected to the back of the hook's fixing plate.

[0016] Furthermore, the disc is fixedly connected to the space below the moving turntable.

[0017] Furthermore, the hook is powered by a cylinder to perform the flipping action. Multiple cylinders are located in the space below the rotating disk. The actuating end of each cylinder is movably connected to the fixed plate, and the fixed end is connected to the bottom surface of the rotating disk and moves with the rotating disk. All cylinders extend outward from the center of the rotating disk in a radial direction, pushing the fixed plate and the hook to rotate around the rotating shaft, thereby realizing the upward flipping action of the hook.

[0018] Furthermore, the hook provides the power required for the flipping action through a curved track located in the space below the motion turntable and in contact with the back side of the hook; the motion turntable drives the hook to rotate, and the hook rotates around the axis under the push of the curved track, realizing the upward flipping action of the hook.

[0019] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0020] 1. Poultry are hung head-down on the racks and enter the head-hanging device. The hooks in the head-hanging device correspond one-to-one with the racks. When the moving plate rotates to the set position, the hooks perform an upward flipping action. During the flipping, the hooks lift the poultry's head and flip it into the rack, changing the poultry's original head-down posture to a posture where the head is at a higher position, the neck is bent, and the torso is horizontal. After this, the poultry leaves the head-hanging device and proceeds to the subsequent waxing process on the assembly line. This ensures that the poultry's head is not covered by wax, while the area below the head is completely immersed in wax, solving the problem of wax contamination during the feather removal process and improving the efficiency of the feather removal operation. Because the poultry's torso is in a horizontal position after passing through the head-hanging device, the fine down feathers on the poultry's legs can be removed more effectively.

[0021] 2. After waxing, the poultry's head remains at a high point, avoiding the risk of contamination caused by wax backflow. The hook is used to push the head upwards, eliminating the need for the guide rail at the connector in existing technology. This allows it to accommodate poultry with different head sizes, making it more reliable in application.

[0022] 3. Driven by the cam mechanism, the hook flips upward, converting the rotational motion from the moving plate into the reciprocating motion of the connecting rod through rollers and non-circular discs, thereby pushing the hook to flip upward. No complex control process is required; mechanical parts can be used to achieve this, which is conducive to the stable and reliable operation of the poultry slaughtering production line.

[0023] 3. The hook can also perform an upward flipping action driven by the cylinder. By controlling the sequence of multiple cylinder actions, the heads of poultry on the corresponding rack can be flipped upward into the rack, changing their head-down posture to a posture with the head at a higher position, the neck bent, and the torso horizontal, thus solving the problem of wax contamination during subsequent waxing operations. Using cylinders instead of cam mechanisms reduces the number of mechanical parts and lowers the overall complexity of the device.

[0024] 4. The hook can also perform an upward flipping action in conjunction with a curved track. Using a curved track instead of a cam mechanism, the shape change of the curved track pushes the hook upward, flipping the poultry's head onto the corresponding rack. This further simplifies the device structure, significantly reduces the number of mechanical parts, lowers the overall complexity of the device, and reduces subsequent maintenance costs.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] The following embodiments provide a head-hanging device for poultry slaughtering lines. It operates synchronously with the poultry slaughtering line, mimicking the way poultry heads are manually turned over. The poultry head is pushed into the hanging rack by a hook, so that the poultry head is in the highest position of the hanging rack, and is held on the hanging rack with the neck bent and the torso horizontal, and then immersed in wax liquid.

[0040] Example 1:

[0041] like Figures 1-2 As shown, the hanging device for a poultry slaughtering line includes a main shaft arranged vertically on a frame 1, a sprocket 2 connected above the main shaft, and multiple hangers 3 arranged in the circumferential direction of the sprocket 2 for hanging poultry.

[0042] The space below the main shaft is connected to the motion plate 4. Multiple head pushing mechanisms 5 are provided in the circumferential direction of the motion plate 4. Each head pushing mechanism 5 corresponds to the hanging frame 3 in the vertical direction. The sprocket 2 rotates synchronously with the motion plate 4. When it rotates to the set position, the head pushing mechanism 5 is activated, flipping the poultry head that is hanging below the hanging frame 3 onto the hanging frame 3, so that the poultry head is at the high point of the hanging frame, forming a state of neck bending and body horizontal. The hanging frame 3, together with the poultry in this state, enters the subsequent waxing operation, solving the problem of waxing contamination, and can also handle poultry with different head sizes.

[0043] As a further implementation, the hanging rack 3 is a component used to hang poultry in a poultry slaughtering line. This embodiment does not limit the specific structure of the hanging rack 3; any mature existing product can be selected. To explain this solution, the hanging rack 3 has three sets of V-shaped grooves arranged side by side. The grooves on both sides engage with the poultry legs, and the groove in the middle is used to engage the poultry head. Before entering the head-hanging device, the poultry legs are engaged in the grooves on both sides, and the head is suspended on the hanging rack 3 with its head facing down. With the synchronous operation of the sprocket 2 and the moving disc 4, when it rotates to the set position, the head-hanging device pushes the poultry head into the V-shaped groove in the middle of the hanging rack 3, so that the poultry head is in a high position, forming a state of neck bending and torso horizontal, thereby mimicking the method of manual operation to solve the problem of wax contamination.

[0044] As a further implementation, the sprocket 2 connected in the space above the main shaft, together with the hanging bracket 3, is part of the poultry slaughtering production line. The sprocket 2 is driven to rotate by the chain, so that the hanging bracket 3 can enter and exit the hanging head device.

[0045] like Figure 3 As shown, the head pushing mechanism 5 includes a hook 51, which is fixedly connected to the fixed plate 52. The fixed plate 52 is rotatably connected to the moving plate 4 via a rotating shaft 53.

[0046] As a further embodiment, the hook 51 is a part used to support the poultry's head. This embodiment does not limit the specific structure and has at least one groove for accommodating the poultry's head. When the head-hanging device is working, the groove of the hook 51 supports the poultry's head and flips it up onto the hanger 3, changing the poultry's original head-down posture to a posture where the head is at a high position, the neck is bent, and the torso is horizontal.

[0047] like Figures 4-5 As shown, the hook 51 is powered by the cam mechanism 6 to perform the flipping action. The cam mechanism 6 includes a disc disposed in the space below the hook 51. The outer edge of the disc has a groove 61. The groove 61 contains a roller 62 corresponding to each hook 51. Each roller 62 is movably connected to one end of a connecting rod 64 through a corresponding connector 63. The other end of the connecting rod 64 is movably connected to the back of the fixing plate 52 of the hook 51. The connector 63 is movably connected to the moving disc 4.

[0048] The disc is fixedly connected to the space below the rotating turntable 4. The groove 61 in the disc forms a non-circular trajectory. The groove 61 is rotatably connected to the roller 62. When the rotating turntable 4 drives the hook 51 and the connecting piece 63 to rotate around the center of the rotating turntable 4 to the set position, the non-circular groove 61 pushes the roller 62 to convert the rotational motion into the reciprocating motion of the connecting rod 64. During the reciprocating motion, when the connecting piece 63 drives the connecting rod 64 to move outward in the radial direction from the center of the rotating turntable 4, it pushes the fixed plate 52 and the hook 51 to rotate around the rotating shaft 53, realizing the upward flipping action of the hook 51, thereby flipping the poultry's head upward into the hanging rack 3, changing the poultry's original head-down posture to a posture with the head at a high position, the neck bent and the torso horizontal.

[0049] As a further implementation, after the upward movement is completed, the non-circular groove 61 pushes the roller 62, which drives the connecting rod 64 to move in the opposite direction through the connector 63, restoring the hook 51 in the upward state to the initial state, thus forming a cycle.

[0050] As a further implementation, when the disc in the cam mechanism 6 rotates, the radial change in its profile forces the roller 62 and the connecting member 63 to move according to a predetermined pattern. Its motion characteristics (displacement, speed, acceleration) are determined by the trajectory formed by the groove 61. Since the moving disc 4 is a rotary component and rotates synchronously with the sprocket 2, when the moving disc 4 rotates to the set area of ​​the disc, the connecting member 63 can gradually push the connecting rod 64 to move outward from the center of the moving disc 4 in the radial direction, thereby pushing the fixed plate 52 and the hook 51 to rotate around the rotating shaft 53, realizing the upward flipping action of the hook 51.

[0051] In this embodiment, the connector 63 is movably connected to the rotating disk 4, transmitting the rotational motion of the rotating disk 4 to the roller 62. The roller 62 rolls in the groove 61 of the disk, and the non-circular groove 61 causes the roller 62, together with the connector 63, to drive the connecting rod 64 to push the fixed plate 52 and the hook 51 to rotate around the rotating shaft 53, thereby realizing the upward flipping action of the hook 51. After the upward flipping is completed, the roller 62, together with the connector 63, moves towards the center of the rotating disk 4, pulling the hook 51 back to its initial state.

[0052] In this embodiment, when the head-hanging device is applied to a poultry slaughtering line, the poultry are hung on the rack 3 with their heads down and enter the head-hanging device. The hooks 51 in the head-hanging device correspond one-to-one with the rack 3, and the sprocket 2 and the moving plate 4 rotate synchronously. When the moving plate 4 rotates to the set position, the hooks 51 perform an upward flipping action under the drive of the cam mechanism 6. During the upward flipping, the head of the poultry is received and flipped into the rack 3, changing the poultry's original head-down posture to a posture where the head is at a high point, the neck is bent, and the torso is horizontal. After that, the poultry leaves the head-hanging device and enters the subsequent waxing process. This ensures that the poultry's head is not covered by wax liquid, while the area below the head is completely immersed in wax liquid, solving the problem of wax liquid contamination during the feather removal process and improving the efficiency of the feather removal operation. Since the torso of the poultry is in a horizontal position after passing through the head-hanging device, the fine down feathers on the poultry's legs can be removed more effectively.

[0053] After being dipped in wax, the poultry's head remains at a high point, avoiding the risk of contamination caused by wax backflow. The hook 51 is designed to push the head upwards, instead of using the guide rail at the connector in existing technology. This allows it to accommodate poultry with different head sizes, making the device more reliable in application.

[0054] Example 2:

[0055] like Figures 6-7As shown, the main structure of the hanging device in this embodiment is the same as that in Embodiment 1. The component that drives the hook 51 to flip up has been replaced. The cam mechanism 6 of the mechanical structure in Embodiment 1 has been replaced with a cylinder 7. That is, multiple cylinders 7 are provided in the space below the moving turntable 4. The actuating end of each cylinder 7 is movably connected to the back side of the fixed plate 52, and the fixed end is connected to the bottom surface of the moving turntable 4 and moves with the moving turntable 4. All cylinders 7 extend outward in a radial direction from the center of the moving turntable 4, thereby pushing the fixed plate 52 and the hook 51 to rotate around the rotating shaft 53, realizing the flipping action of the hook 51. After the flipping is completed, the cylinder 7 retracts, pulling the hook 51 back to the initial state.

[0056] When applied to a poultry slaughtering line, this embodiment controls the sequential action of multiple cylinders 7 to flip the heads of poultry on the corresponding racks 3 upwards, changing their head-down posture to one with their heads at a higher position, necks bent, and torsos horizontal. This solves the problem of wax contamination during subsequent waxing operations. This embodiment uses cylinders 7 instead of the cam mechanism 6 in Embodiment 1. While reducing the number of mechanical parts and lowering the overall complexity of the device, it requires more investment in controlling multiple cylinders 7.

[0057] Example 3:

[0058] like Figures 8-9 As shown, the main structure of the hook device in this embodiment is the same as that in Embodiment 1. The component that drives the hook 51 to flip upwards has been replaced. The cam mechanism 6 of the mechanical structure in Embodiment 1 is replaced with a curved track 8. The curved track 8 forms a spline curve or a composite curve of multiple segments according to the motion trajectory required for the hook to rotate one revolution. Specifically, a curved track 8 is provided in the space below the motion turntable 4, located on the back side of the hook 51. When the motion turntable 4 drives the hook 51 to rotate, the back side of the hook 51 contacts the curved track 8. Under the push of the curved track 8, the hook 51 rotates around the rotating shaft 53, realizing the upward flipping action of the hook 51. After the upward flip is completed, the hook 51 returns to its initial state under its own weight.

[0059] When this embodiment is applied to a poultry slaughtering line, the shape design of the curved track 8 is used to flip the heads of the poultry on the corresponding rack 3 upwards into the rack 3, changing the head-down posture to a posture with the head at a high point, the neck bent and the torso horizontal, thus solving the problem of wax contamination during subsequent waxing operations.

[0060] In this embodiment, a curved track 8 is used instead of the cam mechanism 6 in the first embodiment. The mechanical structure is simpler than that of the first embodiment, reducing the use of mechanical parts and the overall complexity of the device. However, the curved track 8 needs to form a spline curve or a multi-segment composite curve according to the motion trajectory required for the hook to rotate one revolution, which requires more investment in the early design and calculation.

[0061] Based on the three embodiments, this solution preferentially selects the solution of Embodiment 1 as the preferred option.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
