Description

Technical Field

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

[0002] In the processing of poultry necks, especially duck necks, removing the skin is a crucial step. The skinning device proposed in patent CN107744008B is used for this purpose. It uses a rotating power module to drive a tearing mechanism in a circular motion in the horizontal plane, and works in conjunction with a lifting mechanism to automatically remove the duck skin. While this skinning device improves efficiency by replacing manual skinning, it was found that the clamping module structure is overly complex when used to peel duck necks. It employs a multi-layered sliding assembly structure including a mounting base, guide seat, and tearing sleeve, and also requires additional components. The system consists of a swing gear, a clamping power module, and other drive components. It relies on an external clamping power module to drive the swing gear, which in turn drives the input gear to rotate. The input gear then drives the clamping module to swing, thereby achieving the closing action of the clamping module to clamp the duck neck. This not only results in a large number of parts and high manufacturing costs, but also means that the symmetrically arranged arc-shaped tear sleeves can only provide elastic clamping force through the compression springs located inside the guide seats. The compression springs and sliding parts are easily affected by impurities such as sewage and grease in the slaughtering environment, leading to frequent jamming failures, increased maintenance costs and downtime, and reduced production efficiency. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a neck-cleaning leather clip.

[0004] The technical solution of this utility model is as follows: A neck-griping claw includes a mounting base and a fixed plate and a movable plate disposed opposite to each other on it. The same end of the fixed plate and the movable plate is fixedly connected to the mounting base and rotatably connected to it, respectively. The other end of each plate extends outward from the mounting base to form a clamping part. The two clamping parts have corresponding notches on opposite sides, and the two notches enclose an annular locking opening. The locking opening is adapted to the shape of a duck neck. An elastic element is connected between the two clamping parts. The movable plate is configured to be clamped and closed with the fixed plate by the elastic force of the elastic element.

[0005] Furthermore, the two gaps are arc-shaped structures with openings facing each other.

[0006] Furthermore, the notches in the fixed plate and the movable plate are the first notch and the second notch, respectively, with the arc-shaped section in the middle of the second notch located inside the extended section of the first notch.

[0007] Furthermore, the movable plate also includes an anti-detachment part located outside the second notch. The anti-detachment part extends toward the fixed plate and abuts against the fixed plate, and the beginning of the two notches corresponds to the middle position of the anti-detachment part.

[0008] As one implementation, the movable plate also includes a contact portion that extends away from the clamping portion and beyond the mounting base. A roller is rotatably provided on the lower side of the contact portion, and the roller is configured to drive the movable plate to rotate under the action of external force.

[0009] Furthermore, the fixed plate has a rotation avoidance tilt angle on the side of the contact portion near the movable plate.

[0010] In one implementation, the elastic element is a tension spring, which is located on the lower side of the clamping part and is positioned close to the mounting base relative to the clamping part.

[0011] Furthermore, connecting rods are vertically provided on the lower sides of the two clamping parts, and the two ends of the tension spring are respectively connected to the lower sides of the two clamping parts.

[0012] Furthermore, the lower sides of the two clamping parts are connected to the tension springs via connecting rods, and the upper end of the connecting rods passes through the clamping parts and is helically connected to them.

[0013] As one implementation method, the vertical distance between the connecting rod and the rotation axis of the movable plate is adjustable, and the fixed plate and the movable plate are of equal thickness, with a thickness of 5mm-8mm.

[0014] This utility model discloses a neck-peeling gripper that replaces the traditional complex clamping module and its complicated external drive mechanism with a simple cooperation between a fixed plate and a movable plate. The opening and closing of the locking port is achieved by the rotation of the movable plate, avoiding the failure probability caused by the frequent opening and closing of the traditional clamping module, thereby reducing maintenance costs and downtime. The external elastic element directly connects the two clamping parts, and the movable plate can be clamped and closed with the fixed plate by the elastic force of the elastic element. Compared with the existing technology that relies on gear transmission for closing, it improves efficiency. Moreover, the closing method under the action of the elastic element can automatically adjust the clamping force according to the size of the duck neck, adaptively clamping the duck neck, improving the adaptability to duck necks of different sizes and shapes, and ensuring a stable and efficient skinning effect.

[0016] Combination Figure 1 This embodiment provides a neck-gripping leather clip, including a mounting base 1 and a fixed plate 2 and a movable plate 3 disposed opposite to each other on it. The same end of the fixed plate 2 and the movable plate 3 are fixedly connected to the mounting base 1 and rotatably connected to it, respectively. The other end of each plate extends outward from the mounting base 1 to form a clamping part. The two clamping parts have corresponding notches on opposite sides, and the two notches enclose an annular locking opening 4. An elastic element is connected between the two clamping parts. The movable plate 3 is configured to be clamped and closed with the fixed plate by the elastic force of the elastic element.

[0017] Mounting base 1 is provided with mounting holes for an external drive mechanism. The external drive mechanism adopts existing technology, such as the lifting mechanism in patent publication number CN107744008A. In use, the gripper is mounted on the lifting mechanism. After clamping the duck neck, it descends with the lifting mechanism to perform the skinning operation.

[0018] This neck-removing gripper replaces the traditional, complex clamping module and its complicated external drive mechanism with the simple cooperation of the fixed plate 2 and the movable plate 3. The opening and closing of the locking port 4 is achieved by the rotation of the movable plate 3, avoiding the failure probability caused by the frequent opening and closing of the traditional clamping module, thereby reducing maintenance costs and downtime. The external elastic element directly connects the two clamping parts. The movable plate 3 can be clamped and closed with the fixed plate 2 by the elastic force of the elastic element. Compared with the existing technology that relies on gear transmission for closing, it improves efficiency. Moreover, the closing method under the action of the elastic element can automatically adjust the clamping force according to the size of the duck neck, adaptively clamping the duck neck, improving the adaptability to duck necks of different sizes and shapes, and ensuring a stable and efficient skinning effect.

[0019] Combination Figure 2 and Figure 3 The two notches are arc-shaped structures with openings facing each other, so as to better fit the cylindrical shape of the duck neck, making the contact between the annular locking opening 4 and the surface of the duck neck more compact and uniform, preventing the duck neck from sliding or deforming during clamping, further improving clamping stability, and ensuring the smooth progress of the peeling process.

[0020] The notches of the fixed plate 2 and the movable plate 3 are the first notch 21 and the second notch 31, respectively. The middle arc-shaped section of the second notch 31 is located inside the extension of the first notch 21. That is, the first and last ends of the two arc-shaped notches are connected. The first and last sections of the first notch 21 are located on the extensions of the first and last sections of the second notch 31, respectively. The middle arc-shaped section of the first notch 21 is located inside the extension of the second notch 31. This allows the annular locking opening 4 formed by the two notches to fit the duck neck more snugly when clamping. In particular, it can enhance the adaptability of clamping for the different thicknesses of different parts of the duck neck and avoid local clamping that is too loose or too tight.

[0021] The movable plate 3 also includes an anti-detachment part 32 located outside the second notch 31. The anti-detachment part 32 extends toward the fixed plate 2 and abuts against the fixed plate 2. The first ends of the two notches correspond to the middle position of the anti-detachment part 32. The anti-detachment part 32 abuts against the fixed plate 2, which can limit the relative position of the two clamping parts when the locking opening 4 is closed, preventing the notch from being over-clamped due to excessive elastic force of the elastic element. At the same time, it prevents the duck neck from coming out of the first end of the notch during processing, thus improving the reliability of clamping.

[0022] The movable plate 3 extends away from the clamping part and has a contact part 33 that extends beyond the inner side of the mounting base 1. A roller 7 is also rotatably provided on the lower side of the contact part 33. The roller 7 is designed to drive the movable plate 3 to rotate under the action of external force. This eliminates the need for a complex transmission structure, simplifies the operation process, and improves the automation efficiency of the equipment.

[0023] To illustrate a specific implementation, consider the lifting mechanism and rotation power module in patent publication number CN107744008A. In this patent, a protruding bump 8 is provided on the outer ring of the guide cylinder (see...). Figure 4 The neck-scratching gripper of this embodiment is installed on the lifting mechanism. When the roller 7 passes the protrusion 8, the neck-scratching gripper can contact or disengage from the protrusion 8 under the action of the lifting mechanism and the rotation power module, thereby opening and closing the locking port 4. After the locking port 4 is closed, it descends with the lifting mechanism to complete the neck-scratching operation.

[0024] Combination Figure 3 The fixed plate 2 has a rotation avoidance tilt angle 22 on the side of the contact part 33 near the movable plate 3, which provides sufficient space for the rotation of the contact part 33 of the movable plate 3, avoids interference between the movable plate 3 and the fixed plate 2 when the movable plate 3 rotates, and ensures that the movable plate 3 can be opened smoothly to the required angle, thereby improving the movement flexibility of the structure.

[0025] An inlet bevel 23 is provided on the outer side of the first notch 21 of the fixed plate 2, opposite to the anti-detachment part 32 of the movable plate 3. The anti-detachment part 32 has a mating bevel on the side facing the fixed plate 2. The inlet bevel 23 and the mating bevel abut against each other to form an inclined fitting plane. The inlet bevel 23 extends outward from the beginning of the first notch 21 and gradually moves away from the movable plate 3. The inclination angle of the mating bevel and the inlet bevel 23 are matched. The inlet bevel 23 provides a smooth guide path for the duck neck to enter the notch. When the duck neck contacts the bevel, it can slide naturally into the annular locking port 4 along the bevel, avoiding the duck neck from getting stuck due to the right angle or protrusion at the entrance of the notch. At the same time, the mating bevel of the anti-detachment part 32 and the inlet bevel 23 form an inclined fitting plane, further enhancing the limiting effect.

[0026] Combination Figure 1 and Figure 2 The elastic element is a tension spring 5. The two ends of the tension spring 5 are connected to the lower side of the two clamping parts respectively, and are set close to the mounting base 1 relative to the clamping parts. While ensuring that sufficient tension is applied to the clamping parts, it avoids interfering with the placement and processing of the duck neck. The elastic characteristics of the tension spring 5 can stably provide the restoring force, ensuring the reliability of the locking port 4 closure. It is also simple in structure, low in cost, and easy to maintain.

[0027] The lower sides of the two clamping parts are respectively connected to the tension spring 5 via connecting rods. The upper end of the connecting rod passes through the clamping part and is screwed to it. The connecting rod can preferably be a bolt 6. The upper end of the bolt 6 is threaded to the clamping part. The tension spring 5 is connected to the lower end of the bolt. The specific connection method includes hanging it on the bolt on the upper side of the bolt head and fixing it by pressing with a nut, or directly hanging it by drilling a hole at the lower end of the bolt, so as to facilitate the disassembly and replacement of the tension spring 5.

[0028] Combination Figure 2 The vertical distance between bolt 6 and the rotation axis of movable plate 3 is adjustable to adjust the clamping lever arm of the clamping part, thereby adjusting the clamping force of the two clamping parts on the duck neck. In use, when roller 7 disengages from protrusion 8, tension spring 5 pulls the two clamping parts inward under the action of elastic force, thereby clamping the duck neck. Furthermore, for ease of processing, fixed plate 2 and movable plate 3 are made of sheet metal of equal thickness, with a thickness of 5mm-8mm, preferably 6mm.
