Description

Technical Field

[0001] This utility model relates to the field of poultry esophagus processing equipment, specifically an esophagus shearing device. Background Technology

[0002] After the esophagus is dissected, foreign objects adhering to the inner wall are exposed. The esophagus then needs to be stripped of excess fat to remove these foreign objects from the inner wall and the grease from the outer wall. Finally, the gizzard is severed from the esophagus. Traditionally, this process was done manually, but this was inefficient. While automated processing equipment has improved efficiency, it still has limitations.

[0003] Taking the patent with publication number CN113197243B as an example, on the one hand, the transport of poultry gizzard esophagus during the entire processing is achieved by multiple chains working together with placement rods, which is complex in structure and difficult to install and debug; on the other hand, the quality of the products processed by this equipment is difficult to guarantee. Specifically, when removing the grease from the esophagus, because there is still fascia connected to the surface of the poultry gizzard in the grease on the outer surface of the esophagus head, the close connection between this fascia and the surface of the poultry gizzard will either cause the poultry gizzard to be torn at the point of connection with the fascia, or it will cause the grease on the outer surface of the esophagus to not be completely removed, thus affecting the quality of the final product. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an esophageal scissor.

[0005] The technical solution of this utility model is as follows: An esophageal scissor includes a frame and a support frame rotatably mounted thereon. The support frame has vertically sliding grippers that can open and close. The upper side of the support frame has a placement tray capable of holding poultry gizzards. The placement tray has a vertically arranged passage opening that allows only the esophagus to pass through. The vertical projection of the opening of the grippers is located inside the passage opening. The frame also has a tube-head slicing knife and an esophageal cutting knife. The blade of the tube-head slicing knife extends between the placement tray and the grippers. The esophageal cutting knife is located below the placement tray and is higher than the tube-head slicing knife.

[0006] As one implementation method, the frame is also provided with a baffle plate and an ejector rod located on the upper and lower sides of the through-port rotation path, respectively. One end of the baffle plate is located on the inner ring of the through-port rotation path, and the other end is located on the outer ring of the through-port rotation path, and is located on the side of the ejector rod opposite to the rotation direction of the placement plate.

[0007] Preferably, the opening is elliptical, and the outer edge of the placement plate has a notch that communicates with the opening. The notch is funnel-shaped with the opening facing outwards, and the two sides of the notch are arc-shaped structures that bulge towards each other.

[0008] More preferably, the tube scriber is an arc-shaped structure whose center coincides with the center of the placement tray.

[0009] As a further implementation, two guide plates are also provided on the frame with a gap, and the gap between the esophagus and the two guide plates coincides, with part of the blade of the esophagus cutting knife extending into the gap between the two guide plates.

[0010] Furthermore, the side of the two guide plates facing the direction of rotation of the placement disk is flared with the opening facing outwards.

[0011] Furthermore, the distances from the center of the tube slicing blade and the center of the esophageal cutting blade to the center of the placement tray are adjustable, and the horizontal heights of the tube slicing blade and the esophageal cutting blade are vertically adjustable.

[0012] The beneficial effects of this utility model are that, by using a tube-head slicing knife to sever the fascia connecting the esophageal tube head and the gizzard before the esophageal cutting knife separates the gizzard from the esophagus, the integrity of the gizzard is ensured, and the grease on the esophagus is thoroughly removed, thus guaranteeing product quality. Furthermore, by using a rotary conveyor instead of the traditional complex conveyor structure that uses multiple chains and placement rods, automated continuous operation is achieved, improving processing efficiency.

[0014] Combination Figure 1 and Figure 2This embodiment provides an esophageal scraping and cutting device, including a frame 1, on which a carrier frame 3 for conveying poultry gizzards is rotatably mounted, and a processing component 6 is also assembled for scraping oil from the esophagus, separating the poultry gizzard from the esophagus, and receiving the processed poultry gizzard and esophagus.

[0015] The processing component 6 includes a tube head slicing knife 61 and an esophageal cutting knife 62. The tube head slicing knife 61 is used to cut the fascia connecting the esophageal tube head and the gizzard, while the esophageal cutting knife 62 is specifically used for separating the gizzard from the esophagus.

[0016] Combination Figure 3 and Figure 4 On the support frame 3, a vertically slidable gripper 4 is provided, and a placement tray 5 for holding poultry gizzards is installed on the upper side of the support frame 3. The placement tray 5 has a vertically opened passage 51 that allows only the esophagus to pass through. The vertical projection of the opening of the gripper 4 falls exactly inside the passage 51, and the gripper 4 can accurately clamp the esophagus extending from the passage 51.

[0017] Combination Figure 1 and Figure 4 The tube-head slicing knife 61 is designed as an arc-shaped structure with its center coinciding with the center of the placement tray 5. Its blade extends between the placement tray 5 and the gripper 4, and can continuously act on the fascia connected to each gizzard when the placement tray 5 rotates with the support frame 3, so as to cut the fascia connecting the esophagus and the gizzard before passing the esophageal slicing knife 62.

[0018] Combination Figure 4 and Figure 6 The esophageal cutting blade 62 is located below the placement tray 5 and is installed at a higher height than the tube head slicing blade 61. At the same time, two guide plates 63 are also spaced on the frame 1. The side of the two guide plates 63 facing the rotation direction of the placement tray 5 is flared outwards. The esophagus can overlap with the gap between the two guide plates 63. Part of the blade of the esophageal cutting blade 62 extends into the gap between the two guide plates 63. As the esophagus rotates with the placement tray 5, it enters the gap between the two guide plates 63 under the action of the two guide plates 63. Part of the blade of the esophageal cutting blade 62 extends into this gap, thereby achieving precise cutting by limiting the esophagus with the help of the two guide plates 63.

[0019] Combination Figure 2An esophageal receiving box 7 is horizontally provided on the lower side of the esophageal cutting knife 62, and an esophageal straightening plate 8 is provided between the esophageal receiving box 7 and the esophageal cutting knife 62. The esophageal straightening plate 8 is an inclined plate set on the side facing the rotation direction of the placement tray 5. After the esophagus has completed the oil removal operation, it is prone to bounce upward or sway laterally due to its own toughness. The inclined esophageal straightening plate 8 can limit and guide the esophagus by contacting the plate surface before it enters the cutting station, guiding the esophagus to naturally return to its position and remain stationary, effectively avoiding the deviation of the cutting position caused by the esophagus shaking, ensuring that the esophageal cutting knife 62 can accurately act on the preset separation point, and further improving the cutting accuracy and product quality stability.

[0020] Combination Figure 4 The opening 51 is oval-shaped to better fit the natural shape of the non-circular connection between the gizzard and esophagus, allowing the connection between the gizzard and esophagus to rest within the oval opening 51. This design also prevents the esophagus from springing up after oil removal, causing the gizzard to detach from the opening 51, and prevents the gizzard from swaying or shifting laterally within the opening 51 during transport. This ensures that the gripper 4 can accurately clamp the esophagus, improving the thoroughness of oil removal and the accuracy of subsequent cutting.

[0021] To optimize the feeding and unloading process, the outer edge of the placement tray 5 is also provided with a notch 52 that communicates with the passage 51. The notch 52 is a funnel shape with the opening facing outward, forming a widened guide channel, which makes it convenient for operators or feeding mechanisms to quickly guide the poultry gizzard and esophagus into the passage 51 without the need for precise alignment, greatly reducing the difficulty of feeding. In addition, the two sides of the notch 52 are arc-shaped structures that bulge towards each other to avoid scratching the esophagus or poultry gizzard.

[0022] In addition, the distance from the center of the tube head slicing knife 61 and the esophageal cutting knife 62 to the center of the placement tray 5 can be adjusted separately, and the horizontal height of the tube head slicing knife 61 and the esophageal cutting knife 62 can also be adjusted vertically to adapt to the processing needs of poultry gizzards and esophagus of different sizes of poultry.

[0023] Specifically, in Figure 4 As can be seen, the esophageal cutting knife 62 is a circular knife that is rotatably mounted on the mounting base. Both the mounting base and the tube-end slicing knife 61 are mounted on the frame 1 by bolts. The mounting base has an elongated hole along the adjustment direction of the esophageal cutting knife 62, thereby realizing the position adjustment of the esophageal cutting knife 62. The tube-end slicing knife 61 is mounted on the frame 1 by a support. The tube-end slicing knife 61 has an elongated hole on the side opposite to the blade that is placed against the center of the disc 5. An elongated hole is also vertically opened on the support, thereby realizing the position adjustment of the tube-end slicing knife 61.

[0024] Combination Figure 5The frame 1 is also equipped with a baffle plate 64, a push rod 65, and a duck gizzard discharge chute 9. The top view projections of the baffle plate 64 and the push rod 65 both fall within the duck gizzard discharge chute 9. The baffle plate 64 and the push rod 65 are located on the upper and lower sides of the rotation path of the passage 51, respectively. One end of the baffle plate 64 is located on the inner circle of the rotation path of the passage 51, and the other end is located on the outer circle of the rotation path of the passage 51, and is on the side of the push rod 65 away from the rotation direction of the placement plate 5. When the support frame 3 drives the placement plate 5 to rotate to this position, the push rod 65 pushes the separated poultry gizzard product from the bottom to the top, while the baffle plate 64 blocks and guides it from the top to detach from the passage 51 and fall into the duck gizzard discharge chute 9, realizing automatic unloading of the poultry gizzard product without manual intervention. This design further improves the automation level of the equipment, avoids operation interruption caused by manual unloading, reduces efficiency loss, and ensures the continuity of the processing flow.

[0025] For the gripper 4, which is vertically slidably mounted on the support frame 3 and can be opened and closed, the support frame 3 is also provided with a guide cylinder 2 on its inner side. The guide cylinder 2 has a sliding groove 21 on its outer ring. The sliding groove 21 includes an ascending groove section, an upper groove section, a descending groove section, and a lower groove section connected sequentially along the outer ring of the guide cylinder 2. The ascending groove section and the descending groove section are both inclined along the axis of the guide cylinder 2. The planes where the upper groove section and the lower groove section are located are perpendicular to the axis of the guide cylinder 2. The guide cylinder 2 also has an outwardly protruding arc-shaped block on the upper side corresponding to the upper groove section and the lower groove section. 22. The clamp 4 includes a mounting base and two clamping plates arranged opposite to each other on it. The middle of the two clamping plates is rotatably connected to the mounting base through a rotating shaft, and the two clamping plates are provided with meshing transmission teeth around the rotating shaft on opposite sides. One end of the two clamping plates is an oiling part, and the other end is a connecting part. A compression spring is connected between the connecting parts of the two clamping plates, and a roller is rotatably provided below the side of one of the clamping plates away from the oiling part. The mounting base is vertically slidably mounted on the support frame 3 and is slidably engaged with the slide groove 21 through a guide wheel. The roller is in contact with the arc-shaped block 22.

[0026] During operation, the gizzards are placed in the passage 51 of the rotating placement tray 5, while the esophagus is suspended and transported with the placement tray 5. When passing the tube head slicing knife 61, the fascia is cut. When the gripper 4 passes the arc-shaped block 22 located on the upper side of the guide cylinder 2, it clamps the esophagus and rotates and moves downward to complete the oil removal work of the esophagus. When passing the lower arc-shaped block 22, the gripper 4 opens again. There is also an esophagus guide rod 10 on the outer side of the corresponding lower trough section. The esophagus guide rod 10 is located on the lower side of the gripper 4. When the open gripper 4 passes by, it removes the esophagus that has not fallen off, so that when the gripper 4 rotates to the lower oil removal position, the new esophagus can be oiled. Finally, the gizzards continue to rotate with the placement tray 5 and when passing the baffle plate 64 and the push rod 65, the gizzards are unloaded.
