Description

Technical Field

[0001] This utility model relates to the field of poultry processing equipment, specifically a neck-skinning device. Background Technology

[0002] In the poultry processing industry, neck skinning is one of the key processes after poultry slaughter. Traditional manual skinning methods are labor-intensive and inefficient, and can no longer meet the needs of large-scale production lines. To achieve automated skinning, the industry has developed a variety of skinning equipment with matching chain conveyor mechanisms. Although these skinning equipment have replaced manual labor and improved skinning efficiency, there are still some shortcomings in the process of skinning poultry necks in conjunction with the chain conveyor mechanism.

[0003] Taking the patent with publication number CN107744008A as an example, the skinning device disclosed in this patent, when used in conjunction with a chain conveyor mechanism, transports the poultry neck to a position near the guide cylinder. The outer edge of the guide disc at the upper end of the guide cylinder has an outward-facing V-shaped guide portion corresponding to the skinning mechanism. The guide portion is inclined on both sides to facilitate the movement of the poultry neck on the conveyor line to the middle of the guide portion, thereby guiding the poultry neck into the space between the two clamping modules of the skinning mechanism. However, during this process, because the surface of the poultry neck is smooth and contains grease, the poultry neck sometimes slides out along the V-shaped guide portion as the guide disc rotates, instead of entering the V-shaped guide portion, resulting in missed skinning. In addition, after the skinning operation is completed, sometimes the skinned neck will get stuck in the two clamping modules of the skinning mechanism, requiring manual removal, which affects the smoothness of automated production. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a neck-skin-scratching device.

[0005] The technical solution of this utility model is as follows: A neck-skinning device includes a frame and a skinning device on it, as well as a material guiding device and a material unloading device located outside the skinning device.

[0006] Specifically, the peeling device includes a rotating frame and a peeling mechanism on it, the peeling mechanism including two peeling claws that can open and close and move vertically; the material guiding device includes a horizontally arranged guide rod, and a lever plate is provided on the upper side of the rotating frame, which is located on one side of the two peeling claws when viewed from above, and the lever plate is configured to be able to rotate to intersect with the guide rod, and the two peeling claws are located between the guide rod and the lever plate; the material unloading device is configured to push out the material on the two peeling claws.

[0007] As one implementation method, a push plate is also rotatably provided on the lower side of the guide rod. The rotation paths of the push plate and the lever plate intersect vertically and are opposite to the rotation direction of the lever plate.

[0008] Furthermore, the plane containing the guide rod is located between the rotation planes of the lever plate and the push plate; both the push plate and the lever plate are arc-shaped structures with arc-shaped openings facing their own rotation direction; the vertical plane containing the guide rod is parallel to the tangent of the rotation path of the two claws, and the distance between them is adjustable; the vertical height of the guide rod is adjustable; the position of the lever plate in the direction in which the guide rod is set is adjustable.

[0009] As a further implementation, the stripping device includes a lever perpendicular to the rotation axis of the two claws, and the two claws are configured to pass over or under the lever.

[0010] Furthermore, the vertical height of the lever is adjustable; the lever is made of rubber.

[0011] This invention automates the entire process of skinning poultry necks. On the one hand, the limiting channel formed by the guide rod and the lever plate can effectively constrain the trajectory of the poultry neck, solving the problem of missed skinning caused by the poultry neck slipping out in traditional equipment and improving the skinning success rate. On the other hand, the automatic unloading device can remove the stuck neck skin in the claw in real time, replacing manual cleaning, greatly reducing labor intensity and ensuring continuous operation of the production line.

[0013] Combination Figure 1 This embodiment provides a neck-skinning device, including a frame 1 and two sprockets arranged laterally opposite each other on it. A chain is wound around the two sprockets. A skinning device 3 capable of skinning poultry necks is provided on the lower side of one of the sprockets. A guide device 4 and a stripping device 5 are provided on the outside of the skinning device 3.

[0014] Specifically, the peeling device 3 includes a rotating frame 32 that rotates synchronously with the corresponding sprocket and a peeling mechanism on the rotating frame 32. The peeling mechanism includes two peeling claws 33 that can open and close and move vertically. The material guiding device 4 includes a horizontally arranged guide rod 41. The rotating frame 32 has a deflector plate 35 on the upper side, which is located on one side of the two peeling claws 33 when viewed from above. The deflector plate 35 is configured to be able to rotate to intersect with the guide rod 41. The two peeling claws 33 are located between the guide rod 41 and the deflector plate 35. The material unloading device 5 is configured to push out the material on the two peeling claws 33.

[0015] Combination Figure 2 and Figure 3 A push plate 42 is also rotatably provided on the lower side of the guide rod 41. The rotation paths of the push plate 42 and the deflector plate 35 intersect vertically, and the rotation directions of the push plate 42 and the deflector plate 35 are opposite, forming a two-way collaborative material guiding mechanism in which the deflector plate 35 actively pushes and the push plate 42 provides reverse auxiliary limiting. When the deflector plate 35 pushes the poultry neck towards the claw 33 in the direction of rotation, the push plate 42, which rotates in the opposite direction, can provide reverse support to the poultry neck from below, preventing the poultry neck from shifting downward due to inertia or slippage of grease. The vertical intersection design of the two further covers the vertical movement space of the poultry neck, reduces the probability of missing the claw, and improves the stability of material guiding.

[0016] The horizontal plane of the guide rod 41 is located between the rotation planes of the paddle plate 35 and the push plate 42, so as to construct a three-dimensional guiding space of the upper paddle plate 35, the middle guide rod 41, and the lower push plate 42. The guide rod 41 laterally limits the horizontal displacement of the poultry neck in the middle, the paddle plate 35 pushes in the rotation direction from above, and the push plate 42 assists in the opposite direction from below. This three-layer structure wraps the movement trajectory of the poultry neck from different dimensions, completely eliminating the poultry neck from moving in the up-down and left-right directions. It is especially suitable for poultry necks with high surface oil content and easy slippage, further improving the guiding accuracy and skinning success rate.

[0017] Both the push plate 42 and the paddle plate 35 are arc-shaped structures with their openings facing the direction of their own rotation, in order to fit the near-cylindrical contour of the poultry neck, reduce the scratching damage to the poultry neck skin during the feeding process, and ensure the quality of poultry meat processing; secondly, the arc-shaped surface with the opening facing the direction of rotation can form a gradual guide, which can push the poultry neck into the space between the two claws 33 more smoothly than the straight surface structure.

[0018] The vertical plane of the guide rod 41 is parallel to the tangent of the rotation path of the two claws 33, and the distance between them is adjustable. That is, the vertical plane of the guide rod 41 is parallel to the outer circle tangent of the corresponding sprocket, and the distance between them is adjustable. On the one hand, the setting of being parallel to the sprocket tangent ensures that the guiding direction of the guide rod 41 is consistent with the movement direction of the poultry neck as it is conveyed by the chain, reducing the movement resistance of the poultry neck during the feeding process and avoiding jamming. On the other hand, the adjustable distance allows for flexible adjustment of the distance between the guide rod 41 and the sprocket according to the thickness of the poultry neck of different types of poultry (such as chickens, ducks, geese) or the chain conveying speed, ensuring that the width of the guiding channel is adapted to the current processing object. It can meet the processing needs of poultry necks of multiple specifications without replacing the entire feeding assembly, thus improving the applicability of the equipment.

[0019] The vertical height of the guide rod 41 is adjustable, further refining the equipment's adaptability to poultry necks of different sizes. For the short and thick necks of small poultry (such as young chickens) or the slender necks of large poultry (such as geese), the vertical height of the guide rod 41 can be adjusted so that it fits precisely against the middle area of ​​the poultry neck. This avoids the problem of the guide rod being too high, which would fail to restrain the lower part of the poultry neck and cause it to be missed, and also avoids the problem of the guide rod being too low, which would compress the poultry neck and cause skin damage. This adjustment does not require disassembling the equipment, is easy to operate, and can quickly respond to the product switching needs of the production line, improving production flexibility.

[0020] The position of the lever 35 in the direction of the guide rod 41 is adjustable, so that during installation and debugging, the lever 35 can be adjusted along the direction of the guide rod 41 to match the position of the two claws 33.

[0021] The unloading device 5 includes a lever 51 perpendicular to the rotation axis of the two claws 33, and the two claws 33 are configured to pass over or under the lever 51.

[0022] The vertical height of the lever 51 is adjustable to ensure that the unloading device 5 can adapt to the position of the claw 33 under different working conditions.

[0023] The lever 51 is made of rubber to prevent the neck skin from breaking or scratching the surface of the poultry neck meat due to rigid impact.

[0024] It should be noted that the guide rod 41, the dial plate 35, and the dial lever 51 mentioned above are all mounted on the frame 1 via brackets. The guide rod 41 is vertically connected to an adjusting rod on the side away from the peeling device 3. The adjusting rod passes through the corresponding bracket, and fastening nuts are provided on the adjusting rods on both sides of the bracket. The position of the guide rod 41 can be adjusted by adjusting the fastening nuts. The dial plate 35 and the dial lever 51 are mounted on the corresponding brackets via supports. The supports have elongated holes for connecting to the brackets in the corresponding adjustment direction, thereby realizing position adjustment, which will not be described in detail here.

[0025] It should be noted that the above-mentioned skinning device can be a skinning device disclosed in the patent with patent publication number CN107744008A, or it can be the skinning device structure shown in this embodiment.

[0026] Specific combination Figure 1 and Figure 4 Regarding the structure of the skinning device 3 in this embodiment: the two sprockets are a driving sprocket and a driven sprocket 2, respectively. The skinning device 3 is located below the driven sprocket 2. The rotating frame 32 rotates synchronously with the driven sprocket 2. The driven sprocket 2 is coaxially connected to a rotating shaft. The rotating frame 32 is synchronously rotated on the rotating shaft to match the rhythm of the chain conveying the poultry neck. A fixed cylinder 31 is also provided on the rotating shaft. The rotating shaft passes through the fixed cylinder 31, and its lower end is fixed to the frame 1. The fixed cylinder 31 and the rotating shaft are connected by a bearing. The frame 32 includes a chuck 34 and a fixed plate below it, as well as several uprights arranged vertically between the chuck 34 and the fixed plate. The uprights are arranged in an array around the outer circumference of the fixed plate. The chuck 34 and the fixed plate are respectively connected to the upper and lower rotating shafts of the fixed cylinder 31. The lever 35 is located at the upper outer edge of the chuck 34, and the chuck 34 has a limiting notch 341 with the opening facing outward at the opening and closing opening of the two claws 33. The lever 35 is located on the side of the limiting notch 341 opposite to the direction of rotation.

[0027] The fixed cylinder 31 includes a cylinder body with a guide groove 312. The guide groove 312 includes an ascending groove section, an upper groove section, a descending groove section and a lower groove section connected sequentially along the outer periphery of the fixed cylinder 31. The ascending groove section and the descending groove section are both inclined along the axial direction of the fixed cylinder 31. The peeling mechanism also includes a fixed seat 36 that is vertically slidably mounted on the upright. Two peeling claws 33 are mounted on the fixed seat 36. The inner side of the fixed seat 36 is also rotatably provided with a first guide wheel 37 that rolls with the inner wall of the guide groove 312.

[0028] The planes containing the upper and lower groove sections are perpendicular to the axis of the fixed cylinder 31. The fixed cylinder 31 also has arc-shaped opening and closing guide rails 311 protruding from the outer side of the upper and lower groove sections, respectively. The center of the opening and closing guide rails 311 coincides with the axis of the fixed cylinder 31. The two claws 33 are horizontally arranged plate-like structures, with one end extending outwards towards the fixed seat 36 to form a clamping part. The two clamping parts are connected by an elastic element, allowing the two claws 33 to adapt to bird necks of different thicknesses, ensuring uniform skinning force. The design ensures even distribution and reduces poultry meat damage. One of the claws 33 is rotatably connected to the fixed base 36 in the middle, and a second guide wheel 38 is rotatably provided at the end opposite to the clamping part, which can abut against the opening and closing guide rail 311. In use, the two claws 33 clamp the poultry neck in the upper groove section and release the neck skin in the lower groove section. Thus, the skinning operation is completed during the descent from the upper groove section to the lower groove section. This achieves spatial separation of the clamping function and the guiding function, with a compact structural layout that maximizes the vertical sliding skinning stroke of the two claws 33.
