Description

Technical Field

[0001] This invention belongs to the field of shrimp peeling equipment technology, specifically relating to an automatic shrimp peeling device and its usage method. Background Technology

[0002] Shrimp peeling equipment is a type of machinery specifically designed for shelling or processing shrimp. This type of equipment is designed to improve efficiency in food processing and reduce the costs and hygiene risks associated with manual labor. Shrimp peeling equipment is typically adjusted to the size of the shrimp to remove the shell more effectively without damaging the shrimp meat.

[0003] A search revealed a Chinese patent with authorization announcement number "CN105852583B" that discloses a slicing-type shrimp peeling device. The device features a skewer with a handle and a sliding blade connected to the handle or skewer via a connector. The handle has a support arm extending to one side, connected to two parallel cantilever arms extending forward. A gap exists between the two cantilever arms, allowing the sliding blade's cutting edge to pass through. Longitudinal tracks are provided on the outer sides of the two cantilever arms, running through both ends. A pressing plate is provided on the back of the sliding blade, with one end of the pressing plate connected to connecting blocks located on both sides of the cantilever arms in the direction of the cutting edge. Each connecting block has a protrusion that fits into the longitudinal track on the same side. When eating crayfish, the skewer can be inserted into the crayfish, gradually unfolding it until it is flat. The sliding blade then slices the crayfish shell, neatly opening it. Once opened, the shrimp meat is neatly arranged, allowing for an elegant way to eat it.

[0004] The above-mentioned technical solution gradually flattens the crayfish during the insertion process, and then uses a sliding knife to cut the crayfish shell to neatly split it open. After breaking it open, the crayfish meat is regular and orderly, and can be eaten elegantly. However, under the needs of large-scale or diversified production, manual operation is not as flexible as automated equipment, and manually peeling crayfish can easily cut people's fingers, causing the risk of cross-contamination, and the efficiency is relatively slow. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic shrimp peeling device and its usage method, aiming to solve the problems in the prior art where manual operation is less flexible than automated equipment under large-scale or diversified production needs, and manual shrimp peeling is prone to cutting people's fingers, causing cross-contamination risks, and is also slow.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] The servo motor is fixedly connected to the output shaft of the support frame.

[0013] A circular plate, which is fixedly connected to one side of the support frame;

[0014] A shrimp-holding trough is formed on the circumferential surface of a circular plate;

[0015] A clamping mechanism includes a triangular support block, a rack, a gear, a small motor, a clamping plate, a limiting post, and a socket. The triangular support block is fixedly connected to the circumferential surface of a circular plate. The small motor is fixedly connected to one side of the triangular support block. The gear is fixedly connected to the output shaft of the small motor. The clamping plate is located on one side of the circular plate. The socket is opened on one side of the circular plate. A limiting post is fixedly connected to the inner wall of the clamping plate. The limiting post is located inside the socket. The rack is fixedly connected to one side of the clamping plate. The rack and the gear mesh with each other.

[0016] A fixing mechanism is provided on the upper side of the support block. 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.

[0017] In a preferred embodiment of the present invention, the fixing mechanism includes an L-shaped support platform, a cylinder, a fixing plate, a separating plate, a needle, and a round hole. The L-shaped support platform is fixedly connected to the upper end of the support block, and the separating plate is fixedly connected to the lower end of the L-shaped support platform. The round hole is opened in the lower inner wall of the separating plate. The cylinder is fixedly connected to the lower end of the L-shaped support platform, and the fixing plate is fixedly connected to the extended end of the cylinder. The needle is fixedly connected to the lower end of the fixing plate, and the needle penetrates the round hole and is used to pierce the shrimp meat under the drive of the cylinder to achieve fixing.

[0018] As a preferred embodiment of the present invention, the surface of the shrimp-holding trough is provided with a second groove, the width of which is the same as that of the needle.

[0019] As a preferred embodiment of the present invention, anti-shrimp arc-shaped plates are fixedly connected to the inner walls of the two sides of the shrimp-holding trough at their close ends, and the anti-shrimp arc-shaped plates are made of stainless steel.

[0020] As a preferred embodiment of the present invention, a long plate is fixedly connected to one side of the L-shaped support platform, an arc-shaped piece is fixedly connected to one side of the long plate, a groove is provided at the lower end of the long plate, a spring is fixedly connected to one side of the arc-shaped piece, and a figure-eight correction plate is fixedly connected to one side of the spring.

[0021] In a preferred embodiment of the present invention, the distance between the long plate and the conveyor belt is 0.5 cm, and a first groove is provided on one side of the clamping piece.

[0022] As a preferred embodiment of the present invention, a placement platform is provided on one side of the conveyor belt, and a shrimp meat collection box and a shrimp shell collection box are provided on the upper end of the placement platform.

[0023] In a preferred embodiment of the present invention, the spring and the figure-eight correction plate are both made of stainless steel, and the shrimp collection box and the shrimp shell collection box are both made of food-grade PP5 material.

[0024] As a preferred embodiment of the present invention, a hexagonal reinforcing ring is fixedly connected to one side of the circular plate, and the hexagonal reinforcing ring is a solid core structure.

[0025] A method for using an automatic shrimp peeler includes the following steps:

[0026] S1. After the conveyor belt transports the headless and deveined shrimp to the designated position, when the shrimp product moves near the circular plate, the servo motor drives the support frame to rotate the circular plate and align the shrimp trough with the conveyed product. The small motor starts working and drives the gear to rotate, thereby driving the rack meshing with it, causing the clamping plate to move inward. The shrimp product is clamped by the sliding of the limiting post in the insertion hole.

[0027] S2. The figure-eight correction plate is connected by a spring and can be slightly deformed according to the size and shape of the shrimp products, and move along the groove on the long plate for correction.

[0028] S3. The cylinder starts, and its extended end pushes the fixing plate downward. The needle on the fixing plate passes through the round hole on the separating plate to further fix the shrimp meat. After the shrimp shell and shrimp meat are separated, the cylinder retracts, the needle disengages from the round hole, the shrimp product is released, the small motor of the clamping mechanism reverses, the clamp opens, and the shrimp product falls into the next process or collection area.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. By fixing a hexagonal reinforcing ring to one end of the circular plate, the overall structure of the equipment is significantly strengthened. The solid core structure of the hexagonal reinforcing ring effectively disperses the centrifugal force generated by the circular plate during high-speed rotation, reducing the risk of deformation or damage caused by external impacts. This design not only improves the rigidity of the circular plate but also enhances the stability of the equipment during long-term operation, thereby extending the service life of the equipment and reducing maintenance costs.

[0031] 2. The 0.5cm gap between the long plate and the conveyor belt, combined with the curved plate and the figure-eight correction plate, ensures that the shrimp are accurately guided and corrected before entering the shrimp loading tank. The first groove on the clamping plate further improves the positioning accuracy of the shrimp during the clamping process, reducing damage caused by improper clamping. These designs optimize the shrimp processing flow, improve processing accuracy, and also increase production efficiency, ensuring the high quality of the final product.

[0032] 3. All food-contact components, such as springs, the figure-eight correction plate, shrimp collection boxes, and shrimp shell collection boxes, are made of stainless steel or food-grade PP material. Stainless steel components are corrosion-resistant and easy to clean, while food-grade PP collection boxes are safe and hygienic, meeting food safety standards. This material selection not only ensures the hygiene of the equipment but also improves food safety, guaranteeing the quality of the final product and consumer health. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figures 1-8 The present invention provides the following technical solutions:

[0046] An automatic shrimp peeling device includes:

[0047] Conveyor belt 1;

[0048] W-shaped placement belt 2, the W-shaped placement belt 2 is disposed on the surface of conveyor belt 1;

[0049] Support block 6 is fixedly connected to one side of conveyor belt 1;

[0050] Servo motor 803 is fixedly connected to one side of support block 6;

[0051] The support frame 802 and the servo motor 803 are fixedly connected to the output shaft of the support frame 802;

[0052] A circular plate 801 is fixedly connected to one side of the support frame 802;

[0053] Shrimp placement trough 13 is formed on the circumferential surface of circular plate 801;

[0054] The clamping mechanism includes a triangular support block 804, a rack 805, a gear 806, a small motor 807, a clamping plate 808, a limiting post 809, and a socket 810. The triangular support block 804 is fixedly connected to the circumferential surface of the circular plate 801. The small motor 807 is fixedly connected to one side of the triangular support block 804. The gear 806 is fixedly connected to the output shaft of the small motor 807. The clamping plate 808 is located on one side of the circular plate 801. The socket 810 is opened on one side of the circular plate 801. The limiting post 809 is fixedly connected to the inner wall of the clamping plate 808 and is located inside the socket 810. The rack 805 is fixedly connected to one side of the clamping plate 808, and the rack 805 and the gear 806 mesh with each other.

[0055] The fixing mechanism is located on the upper side of the support 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.

[0056] In a specific embodiment of the present invention, the device comprises two sets of rack 805, clamping plate 808, limiting post 809, and insertion hole 810. Conveyor belt 1 continuously transports shrimp to be processed. W-shaped placement belt 2 arranges the shrimp in a specific pattern for subsequent processing. Servo motor 803 serves as the power source for rotational motion. Support block 6 provides support. Support frame 802 is used to fix servo motor 803 and ensure its stable operation. Circular plate 801 has a shrimp placement groove 13 on its circumferential surface for placing individual shrimp for easy subsequent operation. Triangular support block 804 provides support for other components in the clamping mechanism. Rack 805 and gear 806 are connected... The meshing mechanism converts linear motion into rotary motion. Gear 806 is fixedly connected to the output shaft of small motor 807. Through meshing with rack 805, it drives clamping plate 808 to move. Small motor 807 serves as the power source for the clamping mechanism. Clamping plate 808 clamps the shrimp through the cooperation of rack 805 and gear 806. Limiting post 809 is inserted into socket 810 to ensure accurate positioning of clamping plate 808 during movement. Socket 810 allows limiting post 809 to be inserted to ensure that clamping plate 808 is fixed in position during operation. After the shrimp is fixed, the shrimp meat can also be fixed through the set fixing mechanism so that it can be separated.

[0057] Please refer to the details. Figures 1-8The fixing mechanism includes an L-shaped support platform 7, a cylinder 1001, a fixing plate 1002, a separating plate 1003, a needle 1004, and a round hole 1005. The L-shaped support platform 7 is fixedly connected to the upper end of the support block 6. The separating plate 1003 is fixedly connected to the lower end of the L-shaped support platform 7. The round hole 1005 is opened in the lower inner wall of the separating 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 penetrates the round hole 1005.

[0058] In this embodiment: the L-shaped support platform 7 provides a stable base platform for the fixing mechanism; the cylinder 1001 serves as a power device providing linear pushing and pulling force; the fixing plate 1002 moves with the movement of the cylinder 1001; the separating plate 1003 is located below the fixing plate 1002 and is used to assist in the separation of the shrimp; the needle 1004 is used to pierce a specific part of the shrimp for subsequent shelling operations; the round hole 1005 allows the needle 1004 to pass through, ensuring that the needle 1004 can accurately act on the shrimp. When the shrimp is delivered to the area below the fixing mechanism... When cylinder 1001 is activated, it pushes fixed plate 1002 downward. Fixed plate 1002 drives needle 1004 downward together. Needle 1004 passes through round hole 1005 on separation plate 1003 and accurately pierces the predetermined position of shrimp body. In this way, shrimp is fixed. The shrimp tail is clamped and rotated continuously by clamping mechanism. Then, needle 1004 can help separate shrimp shell and shrimp meat through further action. After the operation is completed, cylinder 1001 retracts. When shrimp meat comes into contact with separation plate 1003, needle 1004 withdraws from shrimp body.

[0059] Please refer to the details. Figures 1-8 The surface of the shrimp tray 13 is provided with a second groove 14, the width of which is the same as that of the needle 1004.

[0060] In this embodiment: the cylinder 1001 is activated, pushing the fixing plate 1002 and the needle 1004 to move downward. Since the width of the needle 1004 is the same as the width of the second groove 14, the needle 1004 will accurately pierce the shrimp body along the direction of the second groove 14, thereby fixing the shrimp or performing pre-treatment work before peeling.

[0061] Please refer to the details. Figures 1-8 The shrimp-proof arc plate 15 is fixedly connected to the inner walls of both sides of the shrimp-holding tank 13 at the near ends. The shrimp-proof arc plate 15 is made of stainless steel.

[0062] In this embodiment, stainless steel was chosen 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, the shrimp will fall off, and the anti-shrimp arc plate 15 will catch the shrimp and prevent it from splashing out.

[0063] Please refer to the details. Figures 1-8 A long plate 1101 is fixedly connected to one side of the L-shaped support platform 7. An arc-shaped piece 1102 is fixedly connected to one side of the long plate 1101. A groove is provided at the lower end of the long plate 1101. A spring 1103 is fixedly connected to one side of the arc-shaped piece 1102. A figure-eight correction plate 1104 is fixedly connected to one side of the spring 1103.

[0064] In this embodiment: the long plate 1101 serves as the mounting base for the additional components. The arc-shaped piece 1102 is designed in an arc shape to help guide and position the shrimp. The groove facilitates the shrimp meat entering the shrimp placement trough 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 in elastic support. The figure-eight correction plate 1104 is designed in a figure-eight shape to correct and adjust the position of the shrimp. When the shrimp is clamped and enters the shrimp placement trough 13, it can play a corrective 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 to ensure that the shrimp is gently corrected to the optimal position. In this way, when the shrimp enters the shrimp placement trough 13, it can be accurately placed above the second groove 14, waiting for the piercing operation of the needle 1004.

[0065] Please refer to the details. Figures 1-8 The distance between the long plate 1101 and the conveyor belt 1 is 0.5cm, and a first groove 12 is provided on one side of the clamping piece 808.

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

[0067] Please refer to the details. Figures 1-8A placement platform 3 is provided on one side of the conveyor belt 1, and a shrimp meat collection box 4 and a shrimp shell collection box 5 are provided on the upper end of the placement platform 3.

[0068] In this embodiment: the placement platform 3 serves as a platform for placing the shrimp meat collection box 4 and the shrimp shell collection box 5. The shrimp meat collection box 4 is used to collect the shrimp meat that has been shelled, 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 shrimp meat in the anti-shrimp arc plate 15 will fall into the shrimp meat collection box 4 due to gravity. After the clamping mechanism clamps the shrimp shells, it will release them after reaching the top of the shrimp shell collection box 5, and the shrimp shells will fall into it.

[0069] Please refer to the details. Figures 1-8 The spring 1103 and the figure-eight correction plate 1104 are both made of stainless steel, while the shrimp collection box 4 and the shrimp shell collection box 5 are both made of food-grade PP5 material.

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

[0071] Please refer to the details. Figures 1-8 A hexagonal reinforcing ring 9 is fixedly connected to one side of the circular plate 801. The hexagonal reinforcing ring 9 is a solid core structure.

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

[0073] The working principle and usage process of this invention are as follows: When the shrimp pass through the conveyor belt 1 and the W-shaped placement belt 2 and are aligned with the shrimp placement slots 13 on the circular plate 801, the servo motor 803 starts and drives the circular plate 801 to rotate, so that each shrimp placement slot 13 is aligned with the clamping mechanism in sequence. At this time, the small motor 807 starts and drives the clamping plate 808 to approach the shrimp through the meshing action of the gear 806 and the rack 805, thus completing the clamping action. After clamping, the servo motor 803 rotates the circular plate 801 again to move the clamped shrimp to the next station for peeling. The design of the limiting post 809 and the insertion hole 810 ensures that the clamping plate 808 will not shift during the operation, thereby ensuring the accuracy and efficiency of peeling.

[0074] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
