[0055] The fixing mechanism is arranged on the upper side of the supporting block 6. When the shrimp tail is clamped by the clamping mechanism, the shrimp meat can be fixed by the fixing mechanism so that it can be separated and processed.

[0056] In a specific embodiment of the present invention, the rack 805, the clamping piece 808, the limiting column 809 and the jack 810 are provided in two groups in the device. The conveyor belt 1 is used to continuously convey the shrimp to be processed. The W-shaped placing belt 2 is used to arrange the shrimp into a specific form for subsequent processing. The servo motor 803 is used as a power source for rotational motion. The support block 6 provides support. The support frame 802 is used to fix the servo motor 803 and ensure its stable operation. The circular plate 801 is provided with a shrimp placing groove 13 on its circumferential surface. The shrimp placing groove 13 is used to place a single shrimp for subsequent operation. The triangular support block 804 provides support for other components in the clamping mechanism. The rack 805 is connected to the gear 806. The gear 806 is fixedly connected to the output shaft of the small motor 807, and drives the clip 808 to move through the meshing action with the rack 805. The small motor 807 serves as the power source of the clamping mechanism. The clip 808 achieves the clamping action of the shrimp through the cooperation of the rack 805 and the gear 806. The limiting column 809 is inserted into the socket 810 to ensure the accurate positioning of the clip 808 during the movement. The socket 810 is for the limiting column 809 to be inserted to ensure that the position of the clip 808 is fixed during work. After the shrimp is fixed, the shrimp meat can also be fixed by the set fixing mechanism so that it can be separated.

[0057] For details, please refer to Figure 1-Figure 8The fixing mechanism includes an L-shaped support platform 7, a cylinder 1001, a fixing plate 1002, a separation plate 1003, a needle 1004 and a circular hole 1005. The L-shaped support platform 7 is fixedly connected to the upper end of the support block 6, the lower end of the L-shaped support platform 7 is fixedly connected to the separation plate 1003, the circular hole 1005 is opened on the lower inner wall of the separation plate 1003, the cylinder 1001 is fixedly connected to the lower end of the L-shaped support platform 7, the fixing plate 1002 is fixedly connected to the extended end of the cylinder 1001, the needle 1004 is fixedly connected to the lower end of the fixing plate 1002, and the needle 1004 passes through the circular hole 1005.

[0058] In this embodiment: the L-shaped support platform 7 provides a stable basic platform for the fixing mechanism, the cylinder 1001 is used as a power device to provide linear push and pull force, the fixing plate 1002 moves with the action of the cylinder 1001, the separation plate 1003 is located below the fixing plate 1002, and is used to assist in the separation of the shrimp body, the needle 1004 is used to pierce a specific part of the shrimp body for subsequent shelling operations, and the circular hole 1005 allows the needle 1004 to pass through, ensuring that the needle 1004 can accurately act on the shrimp body. When the shrimp is sent to the bottom of the fixing mechanism , the cylinder 1001 is started, pushing the fixed plate 1002 to move downward, and the fixed plate 1002 drives the needle 1004 to move downward together. The needle 1004 passes through the round hole 1005 on the separation plate 1003 and accurately pierces the predetermined position of the shrimp body. In this way, the shrimp is fixed, and the shrimp tail is clamped by the clamping mechanism and rotated continuously. After that, the needle 1004 can help separate the shrimp shell and shrimp meat through further actions. After completing the operation, the cylinder 1001 retracts, and when the shrimp meat contacts the separation plate 1003, the needle 1004 withdraws from the shrimp body.

[0059] For details, please refer to Figure 1-Figure 8 A second groove 14 is provided on the surface of the shrimp slot 13 , and the second groove 14 is consistent with the width of the needle 1004 .

[0060] In this embodiment: the cylinder 1001 is started, pushing the fixing plate 1002 and the needle 1004 to move downward. Since the width of the needle 1004 is consistent with the width of the second groove 14, the needle 1004 will accurately penetrate the shrimp body along the direction of the second groove 14 to fix the shrimp or perform pre-treatment work before peeling the shell.

[0061] For details, please refer to Figure 1-Figure 8 The inner walls of both sides of the shrimp trough 13 are fixedly connected with shrimp-proof arc plates 15 near the ends, and the material of the shrimp-proof arc plates 15 is stainless steel.

[0062] In this embodiment, stainless steel is selected because it has good corrosion resistance, is easy to clean, is suitable for food processing environments, and will not cause infection when in contact with shrimp. When the needle 1004 is withdrawn from the shrimp body, the shrimp will fall, and the shrimp will be caught by the shrimp anti-arc plate 15 without splashing out.

[0063] For details, please refer to Figure 1-Figure 8 One side end of the L-shaped support platform 7 is fixedly connected to a long plate 1101, one side end of the long plate 1101 is fixedly connected to an arc-shaped piece 1102, a groove is provided at the lower end of the long plate 1101, one side of the arc-shaped piece 1102 is fixedly connected to a spring 1103, and one side of the spring 1103 is fixedly connected to an eight-shaped correction plate 1104.

[0064] In this embodiment: the long board 1101 serves as a mounting base for the additional components, the arc-shaped piece 1102 is designed to be arc-shaped, which helps to guide and position the shrimp body, and the groove facilitates the shrimp to enter the shrimp slot 13. One end of the spring 1103 is fixedly connected to one side of the arc-shaped piece 1102, and the other end is fixedly connected to the figure-eight correction plate 1104, which plays a role of elastic support. The figure-eight correction plate 1104 is designed to be figure-eight, which is used to correct and adjust the position of the shrimp body. When the shrimp is clamped and enters the shrimp slot 13, it can play a correction role to prevent the shrimp from bending. Under the action of the spring 1103, the figure-eight correction plate 1104 will be appropriately adjusted according to the size and shape of the shrimp body to ensure that the shrimp body is gently corrected to the optimal position. In this way, when the shrimp body enters the shrimp slot 13, it can be accurately placed above the second groove 14, waiting for the puncture operation of the needle 1004.

[0065] For details, please refer to Figure 1-Figure 8 The distance between the long plate 1101 and the conveyor belt 1 is 0.5 cm, and a first groove 12 is formed at one side end of the clip 808 .

[0066] In this embodiment: the spacing between the long board 1101 and the conveyor belt 1 is 0.5 cm, ensuring that there is enough space between the long board 1101 and the conveyor belt 1 for the shrimp to pass through, while not being too large to cause the shrimp to deviate significantly or become unstable during the conveyance process. The first groove 12 is designed to better adapt to the shape of the shrimp body, especially in the clamping process. The first groove 12 can better fit the curve of the shrimp body, reduce the uneven pressure distribution on the shrimp body during clamping, and thus avoid damage to the shrimp body. Through the reasonable spacing design between the long board 1101 and the conveyor belt 1, and the first groove 12 on the clamping piece 808, the entire device can handle the shrimp body more accurately and gently during the conveying and clamping process of the shrimp, ensuring that the shrimp is in a suitable position before entering the shrimp trough 13 and is effectively protected during the clamping process.

[0067] For details, please refer to Figure 1-Figure 8A placing table 3 is provided on one side of the conveyor belt 1, and a shrimp meat collecting box 4 and a shrimp shell collecting box 5 are provided on the upper end of the placing table 3.

[0068] In this embodiment: the placing table 3 serves as a placement platform for the shrimp collection box 4 and the shrimp shell collection box 5. The shrimp collection box 4 is used to collect the shelled shrimps, and the shrimp shell collection box 5 is used to collect the peeled shrimp shells. When one of the circular plates 801 reaches the bottom, the shrimps in the shrimp anti-arc plate 15 will fall into the shrimp collection box 4 due to gravity. After the clamping mechanism clamps the shrimp shells, it will reach the top of the shrimp shell collection box 5 and release it, and the shrimp shells will fall into it.

[0069] For details, please refer to Figure 1-Figure 8 The materials of the spring 1103 and the eight-shaped correction plate 1104 are both stainless steel, and the materials of the shrimp collection box 4 and the shrimp shell collection box 5 are both edible grade PP5 material.

[0070] In this embodiment: stainless steel has excellent corrosion resistance and can be used for a long time in a humid environment without rusting. PP5 is a food-grade plastic with good chemical stability and hygiene, and is suitable for direct contact with food. PP5 material has good temperature resistance and can be used in a wide temperature range, and is both heat-resistant and cold-resistant.

[0071] For details, please refer to Figure 1-Figure 8 One side end of the circular plate 801 is fixedly connected with a hexagonal reinforcement ring 9, and the hexagonal reinforcement ring 9 is a solid core structure.

[0072] In this embodiment: the hexagonal reinforcement ring 9 is hexagonal in shape and has a solid structure. The design of the hexagonal reinforcement ring 9 is intended to increase the structural strength and stability of the circular plate 801. Since the circular plate 801 needs to carry multiple shrimp troughs 13 and a clamping mechanism, the hexagonal reinforcement ring 9 can provide additional support therefor to prevent deformation or damage when rotating at high speed or being subjected to external forces.

[0073] The working principle and use process of the present invention are as follows: when the shrimps are aligned with the shrimp placing slots 13 on the circular plate 801 through the conveyor belt 1 and the W-shaped placing belt 2, the servo motor 803 starts to drive the circular plate 801 to rotate, so that each shrimp placing slot 13 is aligned with the clamping mechanism in turn. At this time, the small motor 807 starts, and through the meshing action of the gear 806 and the rack 805, the clamping piece 808 is driven to approach the shrimp to complete the clamping action. After clamping, the servo motor 803 rotates the circular plate 801 again to move the clamped shrimps to the next station for shelling. The design of the limit column 809 and the jack 810 ensures that the clamping piece 808 will not be offset during the working process, thereby ensuring the accuracy and efficiency of shelling.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
