Description

Technical Field

[0001] This utility model relates to a cutting device, specifically a chicken claw tendon cutting and separating device. Background Technology

[0002] In Chinese cuisine, "phoenix tendon" typically refers to the ligamentous part of chicken feet, specifically the thick tendons (flexor tendons) inside the foot. This part is rich in collagen and has a chewy texture, making it a common ingredient in snacks and dishes. Traditionally, this involves manual cutting. First, a vertical cut is made near the chicken foot bone (the end cartilage) to sever the tendon, i.e., the ligament. However, because the ligament is quite hard, cutting is difficult. After cutting, the chicken foot bone is then cut along this area. Manual cutting is laborious and inefficient. To address this, invention application (CN115251131A) discloses an integrated machine for chicken feet and phoenix tendons, relating to the field of poultry processing technology. This machine solves the technical problems of existing technologies requiring manual cutting, resulting in low production efficiency, slow processing, and inconsistent product quality due to manual operation. The main frame has a processing platform fixedly installed outside it. A cutting box is installed on the upper part of the processing platform. A skeleton conveying device is installed inside the main frame. A vertical cutting structure for the phoenix tendon, a tail-cutting structure for the phoenix tendon, and a brittle bone cutting structure are installed inside the cutting box. An outer cover is fixedly installed below the main frame. This invention allows operators to place chicken feet on a fixture, which is then automatically clamped, and the cutting blades automatically cut, separating the phoenix tendon, brittle bone, and chicken feet in one go. This achieves industrialized automated processing of chicken feet, improving production efficiency and resulting in good quality cutting and separation. However, this type of equipment results in a smaller cut at the junction of ligaments and cartilage, meaning the overall cut phoenix tendon is relatively small, failing to fully utilize this part of the chicken foot. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a chicken claw tendon cutting and separating device that can fully cut off the ligaments and cartilage of chicken claws, resulting in larger and higher-quality cut products.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a chicken claw tendon cutting and separating device, comprising a conveyor chain plate and chicken claw placement molds fixed on the outer sides of each plate of the conveyor chain plate. The closed conveyor chain plate is driven to rotate cyclically by a driving device. Each chicken claw placement mold is provided with a groove structure that is recessed inward in the middle. The chicken claw is placed in the groove structure, and a tendon-breaking vertical circular cutter is provided on the straight line where the chicken claw ligament moves. A chicken claw cutting pressure belt is provided above the chicken claw placement mold at the rear end of the tendon-breaking vertical circular cutter. The chicken claw cutting pressure belt is closed and driven to rotate by a driving device. A special-shaped cutter is fixed between the chicken claw cutting pressure belt and the chicken claw placement mold. The front end of the special-shaped cutter is a pointed structure with a blade. The rear part of the special-shaped cutter is provided with an end cartilage cutting blade that is integral with the pointed structure and inclined. The pointed structure of the special-shaped cutter is aligned with the ligament between the cutting part of the tendon-breaking vertical circular cutter on the chicken claw and the end cartilage. The end cartilage cutting blade corresponds to the cartilage part at the outer end of the chicken claw.

[0005] Furthermore, the chicken feet placement mold is composed of multiple partitions, and each partition has a U-shaped or V-shaped groove on its surface.

[0006] Furthermore, the bottom of the irregular-shaped cutter is provided with a hopper that extends to the outside of the conveyor chain plate.

[0007] Furthermore, a vertical circular cutter for dividing chicken feet is provided on the rear side of the conveyor chain plate, and the bottom edge of the circular cutter is aligned with the foot connection part of the chicken feet.

[0008] Furthermore, a discharge hopper extending to the outside is provided at the bottom rear end of the conveyor chain plate.

[0009] Furthermore, it also includes a frame for supporting the cyclic rotation of the fixed conveyor chain plate, and the vertical cutting circular cutter for cutting tendons and the circular cutter for dividing chicken feet are covered with an outer cover that is fixedly connected to the frame.

[0010] Furthermore, the vertical cutting circular cutter for tendon breaking and the circular cutter for chicken claw splitting are driven to rotate by their respective motors.

[0011] Furthermore, the chicken claw cutting and pressing belt is driven to rotate by a geared motor fixed above the frame.

[0012] In operation, when the chicken foot is conveyed to the vertical cutting circular cutter, the cutter vertically cuts the ligament near the tarsal bone, severing the ligament and facilitating the subsequent insertion of the shaped cutter tip. As the cutter moves backward, the chicken foot cutting pressure band and the chicken foot placement mold clamp the main chicken foot. Under the clamping and pushing force, the chicken foot is not only more firmly fixed but also facilitates subsequent cutting. The tip of the shaped cutter first inserts into the ligament-cutting area and continues cutting along the tarsal bone surface towards the tarsal bone until it passes the inclined end of the shaped cutter. The cartilage cutting blade completely cuts off the ligaments in the tarsal bone area. After cutting, the chicken foot can continue to move backward and then be cut by the chicken foot dividing circular cutter to separate the foot from the tarsal bone. The chicken foot is continued to be pushed backward by the conveyor chain and the chicken foot cutting pressure belt. During this process, it gradually comes into contact with the special-shaped cutter, which gradually inserts and cuts. The ligaments, fascia and other tissue structures on the upper surface of the special-shaped cutter are shaved outward. The ligaments and fascia in the tarsal bone and cartilage (i.e., tarsal bone) area of ​​the chicken foot can be picked off and cut off completely. The cut product is larger and of better quality.
