Detailed ways

Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

A chicken hamstring ring cutting machine, as shown in Figure 1, is composed of a lifting cylinder 1, a bracket 2, a knife seat platform 4, a rotating seat 10, a clamping cylinder 9 and a tendon cutting tool 11, and the lifting cylinder is fixed on the bracket , the cylinder head of the lifting cylinder is fixed on the upper plate of the knife seat platform below the support. The four jiaos of the upper panel of the tool holder platform are equipped with linear bearings 3 respectively, and the linear bearings are slidably installed on two pairs of vertical shafts 12 between the support and the workbench 13, and the tool holder platform can be driven to reciprocate up and down by the lifting cylinder.

As shown in Figure 2, on the front panel of the tool holder platform, a rotating seat with an open lower end is installed in rotation. The lower end opening of the rotating seat is in an inverted U-shaped structure. The installation structure of the rotating seat and the front panel of the tool holder platform is as follows: In the middle part of the rotating seat, there is a rotating slideway 16 with the same shape as the rotating seat. The rotating slideway is connected with the front panel of the tool holder platform through a needle roller bearing 14. The needle roller bearing is a needle roller bearing with a stepped shaft. One end of the needle roller bearing is stuck in the rotating slideway, and the other end is fixed with the front panel of the tool seat platform by screws; a toothed belt 7 is formed on the side surface of the rotating seat, and the toothed belt meshes with the gear 6 above it. The gear is vertically slipped through the front panel of the tool holder platform and connected with the servo motor 5 installed at the lower end of the tool holder platform. Sensors 15 are respectively installed on the front panel of the seat platform relative to the two lower ends of the swivel seat. The sensor is a proximity sensor. When left or right, if the sensor on one side fails to detect the signal of the sensor, it will notify the feeding motor to stop working, so the sensor provides the left and right limit function of the rotating base and provides data for the positioning of the rotating base.

A tool holder 8 is installed on the front surface of the swivel seat, a clamping cylinder is installed on the tool holder, and a pair of rib-cutting cutters whose heads are hook-shaped are respectively symmetrically installed on the cylinder head of the clamping cylinder and the lower end of the cylinder body, wherein , the opening of the rib-cutting cutter is upward, and the opening of the other rib-cutting cutter is downward. The clamping cylinder installed on the rotating seat can clamp the chicken leg, so that the tendon-cutting cutter is close to the leg bone, which is strong but not strong. Cracking the bones solves the problem of non-round chicken leg bones, and the hook-shaped knife on the head of the tendon cutting tool can hook the hamstrings on the chicken legs. Through the rotation of the rotating seat, the hook-shaped small hook is driven to break the chicken hamstrings.

The working process of this chicken hamstring ring cutting machine is as follows: the lifting cylinder lifts the knife seat platform, the rotating seat is in the passing state, that is, the opening is directly below, the clamping cylinder is in the open state, and the chicken legs are transmitted to the rotating seat through the matching transmission device The specified position below and stop the transmission, so that the chicken leg is fixed directly under the cutting tool holder. The lifting cylinder presses down and transmits to the knife seat platform so as to drive the rotating seat to move downward so that the chicken leg bone is located in the middle of the tendon cutting tool. The clamping cylinder performs the clamping operation. Since the cylinder head of the clamping cylinder is connected with the tendon cutting tool, and the cylinder body of the clamping cylinder is connected with another rib cutting tool, the two tendon cutting tools can be fully attached to the chicken leg bone, which makes The strength of the two tendon cutting knives acting on the bone of the chicken leg is moderate. Then, the servo motor rotates the rotating base through the toothed belt on the gear meshing rotating base, so that the tendon cutting cutter cuts on the chicken leg bone. The circumcision machine adopts double-knife cutting, so the rotary base only needs to rotate about 180 degrees to complete the circumcision. The clamping cylinder opens the rib cutting tool, and the rotating seat resets, so that the rotating slide of the rotating seat returns to the initial position, thereby completing a cutting operation.

This embodiment is illustrative rather than restrictive, so the scope of protection of the present invention cannot be limited accordingly. All other implementations obtained by those skilled in the art according to the technical solution of the present invention also belong to the protection of the present invention scope.
