[0036] In the description of the present invention, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a welding connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 to Figure 2 As shown, a preferred embodiment of the present invention provides a shrimp decapitation device, comprising a first driving member 100, a decapitation wheel 200, a conveyor belt 300 and a clamping frame 400, wherein the first driving member 100 is used to provide a rotational driving force; the decapitation wheel 200 is connected to a first output end 110 of the first driving member 100, and the decapitation wheel 200 is provided with a plurality of stripping teeth 210 along its circumference; the conveyor belt 300 is used to transport shrimp bodies; the interior of the clamping frame 400 is provided with a plurality of stripping teeth 210 for the conveyor belt 300 to pass through from back to front. The channel 410 through which the shrimp passes is provided, and the top of the clamping frame 400 is provided with a processing opening 420 communicated with the channel 410. The head removal wheel 200 is arranged on the processing opening 420. The stripping teeth 210 extend into the channel 410. When the conveyor belt 300 passes through the first channel 410, the two sides of the conveyor belt 300 are bent upward relative to each other to clamp the shrimp body in a vertical state for conveying. When the shrimp body to be processed passes through the processing opening 420, the stripping teeth 210 abut against the shrimp head shell and scrape the shrimp head shell away.

[0038] In the shrimp deheading device based on the above technical features, the deheading wheel 200 is controlled to rotate by the first driving member 100 so that the stripping teeth 210 rotate, and the channel 410 enables the two sides of the conveyor belt 300 to bend upward relative to each other so as to clamp the shrimp bodies in a vertical state for conveying one by one. When the shrimp bodies to be processed pass through the processing port 420, the rotating stripping teeth 210 scrape the edges of the shrimp head shells to strip the shrimp head shells upwards, thereby achieving the deheading effect and retaining the shrimp head meat on the shrimp bodies. There is no need to accurately locate the positions of each shrimp body, and the production efficiency is high and has good economic benefits.

[0039] In this embodiment, a transmission assembly 500 is provided between the first driving member 100 and the head removal wheel 200, and the transmission assembly 500 includes a first transmission wheel 510, a second transmission wheel 520, a rotating shaft 530 and a transmission belt 540. The first transmission wheel 510 is connected to the first output end 110 of the first driving member 100; one end of the rotating shaft 530 is connected to the head removal wheel 200, and the other end of the rotating shaft 530 is connected to the second transmission wheel 520; the transmission belt 540 is connected to the first output end 110 of the first driving member 100; The de-heading wheel 200 is driven to rotate by the transmission belt 540 between the first transmission wheel 510 and the second transmission wheel 520, so as to control the distance from the first driving member 100 to the clamping frame 400 and avoid position interference. Moreover, the transmission belt 540 can mitigate impact and vibration loads and run smoothly without noise. When the de-heading wheel 200 is overloaded, the transmission belt 540 can slip on the first transmission wheel 510 and the second transmission wheel 520 to prevent damage to other components.

[0040] Furthermore, the transmission assembly 500 also includes a connecting plate 550, one end of which is rotatably connected to the rotating shaft 530 via a bearing seat, and the other end of the connecting plate 550 is rotatably connected to the first output end 110 of the first driving member 100 via a bearing seat. During the rotation of the deheading wheel 200, the stripping teeth 210 are in direct contact with the shrimp body, and the connecting plate 550 is configured to be rotatably connected to the first output end 110 of the first driving member 100, so that the deheading wheel 200 can rotate slightly with the first output end 110 as the center, that is, the deheading wheel 200 can automatically float up and down freely according to the size and height of the shrimp body, thereby ensuring that the deheading process is not affected by shrimp bodies of different sizes, and the processing is more applicable.

[0041] In this embodiment, it also includes a frame 600, a second driving member 700, a first conveying wheel 800 and a second conveying wheel 900. The second driving member 700 is used to provide a conveying driving force and is installed on the frame 600. The first conveying wheel 800 is connected to the second output end 710 of the second driving member 700 and is installed on the frame 600. The second conveying wheel 900 is installed on the frame 600. The conveyor belt 300 is transmission-connected to the first conveying wheel 800 and the second conveying wheel 900. The second driving member 700 is used as a driving source to realize automatic conveying of the conveyor belt 300, and the degree of automation is high.

[0042] In order to ensure that the shrimp heads and shells can be removed from the shrimp bodies being transported, the linear speed of the stripping teeth 210 in the head removal wheel 200 needs to be greater than the conveying speed of the conveyor belt 300 to ensure that the stripping teeth 210 carry the shrimp heads and shells forward and separate them from the shrimp bodies.

[0043] Furthermore, it also includes a support plate 610, which is arranged on the outside of the frame 600, and the clamping frame 400 is arranged on the support plate 610. The position of the conveyor belt 300 that is bent upward can be changed by adjusting the position of the support plate 610.

[0044] In this embodiment, combined with Figure 3 As shown, the clamping frame 400 is provided with a first side wall 430 and a second side wall 440 inside, the first side wall 430 and the second side wall 440 are arranged opposite to each other to define the channel 410, the first conveying wheel 800 and the second conveying wheel 900 tighten the conveying belt 300, and the shrimp body is placed on the conveying belt 300. When conveyed to the clamping frame 400, under the action of the first side wall 430 and the second side wall 440, the flat shrimp body can be clamped into a vertical direction with the back facing up and the belly facing down, and conveyed along with the conveying belt 300, and the shrimp body will be straightened in the process of being squeezed by the conveying belt 300, providing an accurate positioning posture for the head removal process. Wherein, the conveying belt 300 adopts a soft flat belt, such as a PVC belt, a nylon belt, etc.

[0045] In this embodiment, the radial height of the first end of the stripping tooth 210 along the head removal wheel 200 is smaller than the radial height of the second end of the stripping tooth 210 along the head removal wheel 200, so that a step corner 211 is formed at the connection position between the first end of any stripping tooth 210 and the second end of an adjacent stripping tooth 210.

[0046] Among them, Figure 6 to Figure 7As shown, the stripping tooth 210 includes a stripping surface 212 and an outer peripheral surface 213, wherein the stripping surface 212 is arranged along the radial direction of the head removal wheel 200, one end of the outer peripheral surface 213 is connected to the top of the stripping surface 212 to define the step corner 211, and the other end of the outer peripheral surface 213 is connected to the bottom end of the adjacent stripping surface 212, and the radial stripping surface 212 ensures that the edge of the shrimp head shell can be effectively clamped during rotation to ensure that the shrimp head shell can be taken away, and the plane where the stripping surface 212 is located is aligned with the central axis of the head removal wheel 200. , wherein the plane where the stripping surface 212 is located passes through the central axis of the head removal wheel 200, or the bottom end of the stripping surface 212 is inclined in the direction opposite to the rotation direction of the head removal wheel 200, that is, the bottom end of the stripping surface 212 of the same stripping tooth 210 and the bottom end of the outer peripheral surface 213 are inclined in the same direction to form a step corner 211 similar to a hook shape, ensuring that the step corner 211 is stuck or hooked on the edge of the shrimp head shell, wherein the edge of the shrimp head shell refers to the junction between the shrimp head shell and the abdominal shrimp shell.

[0047] Furthermore, the step corner 211 is an acute angle, the angle α of the longitudinal section of the step corner 211 is 10° to 80°, and the angle β formed by the other end of the outer peripheral surface 213 and the bottom end of the adjacent peeling surface 212 is 10° to 90°, so that the step corner 211 can hook the shrimp head shell to ensure the peeling effect on the shrimp head shell. Among them, the angle α is preferably 60°, and β is preferably 85°. In this embodiment, the edge of the step corner 211 is in a concave arc shape, and the edge curvature of the step corner 211 is less than the edge curvature of the shrimp head shell, so that the step corner better fits the shape of the shrimp head shell, expands the area of ​​contact with the shrimp head shell, and further improves the peeling effect on the shrimp head shell.

[0048] Furthermore, the outer peripheral surface 213 is an inwardly concave arc surface, which matches the arc-shaped step corner 211. The outer peripheral surface 213 is directly processed into a downwardly concave arc surface to form the arc-shaped step corner 211, which greatly reduces the difficulty of production and processing.

[0049] In this embodiment, it also includes a limiting side plate 220, which is arranged on both sides of the head removal wheel 200, and the stripping teeth 210 are located between the limiting side plates 220 on both sides. The limiting side plates 220 on the left and right sides play a limiting role on the conveyor belt 300, ensuring that the shrimp bodies carried by the conveyor belt 300 can pass through the stripping teeth 210 one by one, thereby improving the stability of its head removal.

[0050] Further, combined with Figure 4 and Figure 5As shown, the diameter of the limiting side plate 220 is larger than the diameter of the head removal wheel 200, that is, larger than the diameter of the outer contour circle formed by each of the stripping teeth 210, so that a U-shaped limiting groove 230 is formed between the limiting side plates 220 and the stripping teeth 210 on both sides, and the conveyor belt 300 passes through the limiting groove 230. When the head removal wheel 200 is rotating, the limiting side plates 220 on both sides can assist the conveyor belt 300 to better clamp the shrimp body, thereby ensuring the separation effect of the shrimp head and shell.

[0051] In this embodiment, connecting parts 240 connected to the limiting side plates 220 are provided on both sides of the deheading wheel 200, and the diameters of the connecting parts 240 are smaller than the diameters of the limiting side plates 220 and the diameters of the outer contour circles formed by the stripping teeth 210, so that gap grooves 250 extending inwardly are formed between the stripping teeth 210, the connecting parts 240 and the limiting side plates 220, and the gap grooves 250 are used to accommodate the two side edges of the conveyor belt 300 after bending, so that the stripping teeth 210 extend into the interior of the conveyor belt 300 to dehead the shrimp bodies.

[0052] In this embodiment, a center hole 260 for connecting a driving member is provided at the center of the decapping wheel 200 to control the rotation of the decapping wheel 200. The stripping teeth 210 are distributed in a circular array relative to the center of the decapping wheel 200 to facilitate processing and manufacturing.

[0053] In this embodiment, combined with Figure 3 As shown, the width of the processing opening 420 is greater than the width of the channel 410, that is, the limiting side plate 220 can extend into the channel 410 through the processing opening 420, and is located on both outer sides of the conveyor belt 300 to assist the conveyor belt 300 to better clamp the shrimp body. The width of the stripping tooth 210 is smaller than the width of the channel 410. More specifically, the width of the stripping tooth 210 is smaller than the width between the two side edges of the conveyor belt 300 after bending, ensuring that the stripping tooth 210 can extend into the interior of the conveyor belt 300, thereby realizing the de-heading operation of the shrimp body.

[0054] The working principle of the shrimp deheading device described in this embodiment is as follows: the conveyor belt 300 directs the head of the shrimp body toward the conveying direction and the back of the shrimp toward the upper direction into the U-shaped channel 410 of the clamping frame 400, and the shrimp body is clamped and squeezed by the conveyor belt 300 to be straightened, and passes through the deheading wheel 200 that can float freely up and down and rotate. Because the linear speed of the stripping teeth 210 is greater than the conveying speed of the conveyor belt 300, the stripping teeth 210 can jam or hook the edge of the shrimp head shell during the rotation process, and quickly scrape the shrimp head shell off the shrimp body, thereby achieving the deheading effect and retaining the shrimp head meat.

[0055] In summary, the above-mentioned embodiments of the present invention provide a shrimp deheading device having the following advantages: (1) the peeling teeth 210 are used to remove the shrimp head shell of the clamped shrimp body during rotation, and the shrimp head meat is retained; (2) the deheading wheel 200 can float freely up and down through the connecting plate 550, and is not affected by the size difference of the shrimp body, and has a wide range of applications; (3) the shrimp bodies are transported to the processing port 420 one by one through the conveyor belt 300 for deheading operation, and no positioning is required, which greatly reduces the difficulty of processing; (4) the structure is simple and the manufacturing production cost is low.

[0056] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
