DETAILED DESCRIPTION

[0029] Figures 1 - 7 It is the best embodiment of the utility model, and the following Figures 1 - 7 The utility model is further described.

[0030] like Figures 1 - 3As shown, a poultry head and neck positioning device (hereinafter referred to as the positioning device) includes a base 10, an inner shaft 1 is arranged at the center of the upper surface of the base 10, and the inner shaft 1 is arranged coaxially with the base 10. An outer shaft 2 is rotatably mounted on the outside of the inner shaft 1, and a chuck 6 is coaxially fixed on the bottom of the outer shaft 2, the chuck 6 is located on the upper part of the base 10, and the chuck 6 is also mounted on the outside of the inner shaft 1, and the chuck 6 and the outer shaft 2 rotate synchronously with the inner shaft 1 as the axis.

[0031] A number of bayonet ports 7 are evenly arranged on the outer periphery of the chuck 6. The inner wall of the bayonet port 7 is open, one side of the opening is the input side, and the other side is the output side. The inclination angle of the input side is smaller than the inclination angle of the output side. The objects to be processed (heads with necks) enter each bayonet port 7 one by one. Since the inclination angle of the input side is smaller than the inclination angle of the output side, when entering the bayonet port 7, the neck 24 (see FIG. Figure 7 ) can be snapped into the inner end of the bayonet 7 more quickly. Arc-shaped guide strips 8 are provided at both ends of the output side of the bayonet 7 to guide the neck 24 when the neck 24 is output.

[0032] The surface of the chuck 6 is provided with guide grooves 9 corresponding to the bayonet 7, and the guide grooves 9 are arc-shaped grooves. A toggle assembly 5 is arranged on the side of each guide groove 9, one side of the toggle assembly 5 is rotatably mounted on the surface of the chuck 6, and the other side of the toggle assembly 5 passes through the corresponding guide groove 9, and the toggle assembly 5 swings back and forth along the contour of the guide groove 9.

[0033] A positioning plate 3 is coaxially arranged on the upper surface of the chuck 6, and a tension spring 4 corresponding to the toggle assembly 5 is arranged on the surface of the positioning plate 3. One end of the tension spring 4 is fixed to the surface of the positioning plate 3, and the other end is hung on the surface of the toggle assembly 5. The tension applied to the toggle assembly 5 by the tension spring 4 drives the toggle assembly 5 to reset after rotation.

[0034] A guide rail 12 is provided at the lower part of the chuck 6, and the guide rail 12 is mounted at the lower part of the chuck 6 through a support rod (not shown in the figure). The guide rail 12 includes an arc segment and a straight segment connected to both ends of the arc segment. The two straight segments are parallel to each other, and an opening of the guide rail 12 is formed at one end of the two straight segments of the guide rail 12 away from the arc segment. The two ends of the open end of the guide rail 12 are spaced from the chuck 6 to form the entrance and exit of the positioning device. The head with the neck 24 is inverted (head facing down) and is hung on the hanging frame (not shown in the figure) to move toward the positioning device. When it moves to the entrance of the guide rail 12, it is clamped in the corresponding bayonet 7, and then rotates along the chuck 6. The head with the neck 24 also provides power for the rotation of the chuck 6. After rotating one circle with the chuck 6, the head with the neck 24 is output from the exit of the guide rail 12 and enters the subsequent process.

[0035] CombinationFigure 4 A driving rail 13 is also provided on the lower surface of the chuck 6, and the driving rail 13 is entirely located inside the guide rail 12. A plurality of connecting rods are provided on the inner circle of the driving rail 13, and the inner ends of the plurality of connecting rods are fixed to the bottom of the inner shaft 1, so as to fix the driving rail 13 to the inner shaft 1.

[0036] The driving rail 13 is a closed-loop vortex structure. The intersection of the straight section and the arc section at the entrance of the guide rail 12 is also the intersection point where the maximum diameter is at the minimum diameter in the driving rail 13. The above-mentioned toggle assembly 5 fits on the outer ring of the driving rail 13 after passing through the corresponding guide groove 9. Due to the relative rotation between the chuck 6 and the driving rail 13, all the toggle assemblies 5 gradually move along the contour of the guide groove 9 to the outer end of the guide groove 9 under the driving action of the outer contour of the driving rail 13 during the rotation of the chuck 6. When the toggle assembly 5 moves to the maximum diameter of the driving rail 13, it is at the outermost section of the guide groove 9. Since the maximum diameter and the minimum diameter of the driving rail 13 are connected, the toggle assembly 5 immediately moves to the minimum diameter of the driving rail 13 after passing the maximum diameter of the driving rail 13. At this time, the toggle assembly 5 is pulled to the inner end of the guide groove 9 under the action of the corresponding tension spring 4 to achieve reset.

[0037] like Figures 5 - 6 As shown, the toggle assembly 5 includes a swing arm, which includes a first swing arm 21 and a second swing arm 22 arranged horizontally, and the first swing arm 21 and the second swing arm 22 are arranged at an acute angle. A swing seat 15 is provided at the bottom of the junction of the first swing arm 21 and the second swing arm 22, and the hexagon socket bolt penetrates the swing arm and the swing seat 15 at the same time and then is screwed into the surface of the chuck 6, and the hexagon socket screw also serves as the swing shaft 14 for the toggle assembly 5 to rotate.

[0038] A support arm 16 is vertically arranged upward at the end of the first swing arm 21, and an arc-shaped lever 19 is arranged at the upper end of the support arm 16. The strength is increased by reinforcing ribs 23 at the top of the lever 19 and the support arm 16. A hooking rod 17 is horizontally arranged in the middle of the support arm 16, and a hanging ring is arranged at the end of the hooking rod 17. The two ends of the tension spring 4 are respectively fixed to the surface of the positioning plate 3 and the hanging ring of the corresponding hooking rod 17.

[0039] A roller shaft 18 is vertically fixed at the end of the second swing arm 22. The roller shaft 18 is fixed to the end of the second swing arm 22 by two upper and lower nuts. A roller 20 is rotatably installed at the bottom of the roller shaft 18. The roller shaft 18 passes through the corresponding guide groove 9 and extends to the bottom of the chuck 6. The roller 20 contacts the outer wall of the driving rail 13.

[0040] The specific working process and working principle are as follows:

[0041] like Figure 7As shown, the neck 24 moves upside down toward the positioning device, and when it moves to the entrance of the guide rail 12, it is clamped in the corresponding bayonet 7, and then rotates along the chuck 6. The head with the neck 24 provides power for the rotation of the chuck 6 at the same time.

[0042] When the head with the neck 24 is mounted in the bayonet 7 and rotates with the chuck 6, when it just enters the bayonet 7, the roller 20 at the bottom of the corresponding toggle assembly 5 is about to move to the maximum diameter of the driving rail 13, that is, the roller shaft 18 in the toggle assembly 5 is about to move to the outermost end of the guide groove 9. As the chuck 6 rotates, the roller 20 at the bottom of the toggle assembly 5 moves to the maximum diameter of the driving rail 13. At this time, the roller shaft 18 in the toggle assembly 5 is about to move to the outermost end of the guide groove 9, and the toggle rod 19 of the toggle assembly 5 is located at the outermost side, and the corresponding tension spring 4 is in the maximum tension state. Figure 7 The state shown by arrow A in the middle.

[0043] When the roller 20 at the bottom of the toggle assembly 5 passes the maximum diameter of the driving rail 13 and immediately moves to the minimum diameter of the driving rail 13, the toggle assembly 5 rotates with the swing shaft 14 as the axis under the tension of the tension spring 4, and the roller shaft 18 moves to the inner end of the guide groove 9. The lever 19 of the toggle assembly 5 contacts the neck 24 with the swing of the toggle assembly 5 and toggles the neck 24 toward the axis of the chuck 6. In the current state, since the head is stuck in the inner end of the bayonet 7, and the upper end of the neck 24 is in a hanging state at the same time, when the lever 19 toggles the neck 24, the head is tightly stuck in the bottom of the chuck 6. An arc-shaped support plate 11 is also provided at the lower part of the inner end of each bayonet 7, and the support plate 11 supports and positions the head, so that each head is in an approximately same tilt state after positioning, thereby achieving accurate positioning of the junction of the head and the neck 24.

[0044] The neck 24 gradually rotates with the chuck 6 to the exit of the positioning device and then is output and enters the subsequent process. At the same time, as the toggle assembly 5 rotates with the chuck 6, the roller 20 at the bottom gradually moves to the maximum diameter of the driving rail 13, that is, the toggle assembly 5 gradually swings outward along the guide groove 9, and the toggle rod 19 gradually separates from the neck 24, so that when it moves to the entrance of the guide rail 12, the neck 24 newly entering the bayonet 7 is toggle, and so on.

[0045] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
