Description

Technical Field

[0001] This utility model belongs to the technical field of double screening machines, specifically a self-cleaning stainless steel shrimp tail double screening machine. Background Technology

[0002] In the traditional shrimp processing industry, the sorting and washing of shrimp tails are crucial steps affecting production efficiency and product quality. Early manual sorting methods were not only labor-intensive and inefficient, but also struggled to maintain consistent hygiene standards. With the widespread adoption of automation technology, mechanical screening equipment has gradually replaced manual operation, but its cleaning and maintenance have become new challenges.

[0003] Existing technologies have the following shortcomings: When screening shrimp tails, current technologies typically employ a fixed-angle screen structure, making it difficult to efficiently discharge the screened shrimp tails. Residual material tends to accumulate, increasing the difficulty and time cost of manual cleaning. Furthermore, traditional screening mechanisms lack dynamic adjustment capabilities, resulting in uneven distribution of shrimp tails on the screen, easily leading to localized accumulation or incomplete screening, affecting screening efficiency and product quality. In addition, fixed screen structures create blind spots during cleaning, making thorough cleaning difficult and prone to bacterial growth over long-term use, failing to meet food processing hygiene requirements. Existing equipment generally relies on a single vibration mode, resulting in low screening efficiency and long processing times, failing to meet the high-efficiency demands of modern aquatic product processing. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a self-cleaning stainless steel shrimp tail screening machine, which solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning stainless steel shrimp tail screening machine, comprising: The equipment body has a pair of stable support legs at the bottom. The top and bottom of the equipment body are respectively provided with a feed inlet and a discharge outlet. A combined frame plate is slidably connected to the bottom of the equipment body. Multiple screen plates are arranged in the combined frame plate. A grading outlet is opened on one side of the equipment body corresponding to the position of the screen plate. Both sides of the screen plate are provided with strip groove plates. Circular buttons are provided on the inner walls of both sides of the combined frame plate. The circular buttons are slidably connected in the strip groove plates. A threaded rod is rotatably connected to the combined frame plate near the top. A servo motor is installed on the combined frame plate. The servo motor is coaxially and fixedly connected to the threaded rod. A nut is threaded onto the threaded rod. A connecting frame is fixedly connected to one side of the nut. The connecting frame is rotatably connected to multiple screen plates. A screening mechanism is also installed inside the main body of the equipment.

[0006] As a further embodiment of this utility model: two connecting plates are fixedly connected to the inner top of the main body of the device, and multiple cleaning nozzles are provided on the connecting plates.

[0007] As a further embodiment of this utility model: the screening mechanism includes a rotating seat fixedly connected to one side of the combined frame plate.

[0008] As a further embodiment of this utility model: a support arm is rotatably connected inside the rotating seat.

[0009] As a further embodiment of this utility model: a drive motor is fixedly connected to the inner bottom of the main body of the device, and a rotating disk is coaxially fixedly connected to the output end of the drive motor.

[0010] As a further embodiment of this utility model: the end of the support arm away from the rotating seat is rotatably connected to a position on the rotating disk away from the axis.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a servo motor to drive a threaded rod, adjusting the position of the nut and connecting frame. This, in turn, pulls multiple sieve plates within the connecting frame to adjust their angles, facilitating the discharge of sieved shrimp tails and making subsequent cleaning of the sieve plates easier. Furthermore, to improve sieving efficiency and reduce sieving time, a matching sieving mechanism is included. A drive motor rotates a rotating disc, causing the support arm to reciprocate along the combined frame and sieve plates. This results in a more even distribution of shrimp tails on the sieve plates and a better sieving effect. Attached Figure Description

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-3 As shown, this utility model provides a technical solution: A self-cleaning stainless steel shrimp tail screening machine includes: The equipment body 1 has a pair of stable support legs 2 at the bottom. The top and bottom of the equipment body 1 are respectively provided with a feed inlet and a discharge outlet. A combined frame plate 3 is slidably connected to the bottom of the equipment body 1. Multiple screen plates 4 are provided in the combined frame plate 3. A grading outlet 5 is provided on one side of the equipment body 1 corresponding to the position of the screen plate 4. A strip groove plate 6 is provided on both sides of the screen plate 4. A round button is provided on the inner wall of both sides of the combined frame plate 3. The round button is slidably connected to the strip groove plate 6. When the device is working, the shrimp tails to be screened are slowly poured into the feed inlet at the top of the equipment body 1. After screening, the shrimp tails with the smallest particle size are discharged from the discharge outlet at the bottom of the equipment body 1. The remaining shrimp tails are discharged from top to bottom in the grading outlet 5 on one side of the equipment body 1 according to the particle size from large to small. The screening of shrimp tails can be completed. A threaded rod 7 is rotatably connected to the top of the combined frame plate 3. A servo motor 8 is installed on the combined frame plate 3. The servo motor 8 is coaxially and fixedly connected to the threaded rod 7. A nut 9 is threadedly connected to the threaded rod 7. A connecting frame 10 is fixedly connected to one side of the nut 9. The connecting frame 10 is rotatably connected to multiple screen plates 4. The main body of the equipment 1 is also equipped with a screening mechanism. When the shrimp tails are initially screened, the servo motor 8 is controlled to drive the threaded rod 7. The rotation of the threaded rod 7 will drive the nut 9 threadedly connected to it to move up and down. The connecting frame 10 can then move accordingly, causing the inclination angle of the screen plate 4 to change. At the same time, the circular knob will slide a certain distance in the strip groove plate 6. The side of the screen plate 4 corresponding to the grading port 5 should be raised to prevent the shrimp tails from being discharged from the grading port 5 before being completely screened. Two connecting plates 11 are fixedly connected to the inner top of the main body 1 of the equipment. Multiple cleaning nozzles 12 are provided on the connecting plates 11. The screening mechanism includes a rotating seat 13 fixedly connected to one side of the combined frame plate 3. A support arm 14 is rotatably connected inside the rotating seat 13. A drive motor 15 is fixedly connected to the inner bottom of the main body 1 of the equipment. A rotating disk 16 is coaxially fixedly connected to the output end of the drive motor 15. The end of the support arm 14 away from the rotating seat 13 is rotatably connected to the rotating disk 16 at a position away from the axis. When screening shrimp tails, in order to make the shrimp tails move continuously on the screen plate 4 to cooperate with the screen plate 4 for screening, this device drives the rotating disk 16 by setting the drive motor 15. When the rotating disk 16 rotates, the support arm 14 on it will drive the rotating seat 13, the combined frame plate 3, and the screen plate 4 to reciprocate, thereby meeting the requirements of shrimp tail screening. It should also be noted that after screening for a certain period of time, the angle of the screen plate 4 needs to be adjusted again by controlling the servo motor 8 so that the screen plate 4 is inclined to the side of the grading port 5 and aligned with the grading port 5. In addition, when it is necessary to clean the screen plate 4, the screen plate 4 can also be rotated at a certain angle to cooperate with the cleaning nozzle 12 for cleaning and maintenance.

[0016] The working principle of this utility model is as follows: First, when the device is working, the shrimp tails to be screened are slowly poured in from the feed inlet at the top of the main body 1. After screening, the shrimp tails with the smallest particle size are discharged from the discharge outlet at the bottom of the main body 1. The remaining shrimp tails are discharged from top to bottom through the grading outlet 5 on one side of the main body 1 according to the particle size from large to small, thus completing the screening of the shrimp tails. Secondly, when the shrimp tails are initially screened, the servo motor 8 is controlled to drive the threaded rod 7. The rotation of the threaded rod 7 will cause the nut 9 connected to it to move up and down, and the connecting frame 10 will move accordingly, causing the inclination angle of the screen plate 4 to change. At the same time, the round button will slide a certain distance in the strip groove plate 6. The side of the screen plate 4 corresponding to the grading port 5 should be raised to prevent the shrimp tails from being discharged from the grading port 5 before being completely screened. Finally, when screening the shrimp tails, in order to make the shrimp tails move continuously on the screen plate 4 to cooperate with the screen plate 4 for screening, this device is equipped with a drive motor 15 to drive the rotating disk 16. When the rotating disk 16 rotates, the support arm 14 on it will drive the rotating seat 13, the combined frame plate 3, and the screen plate 4 to reciprocate, thereby meeting the requirements of shrimp tail screening. It should also be noted that after screening for a certain period of time, the angle of the screen plate 4 needs to be adjusted again by controlling the servo motor 8 so that the screen plate 4 is inclined to the side of the grading port 5 and aligned with the grading port 5. In addition, when it is necessary to clean the screen plate 4, the screen plate 4 can also be rotated at a certain angle to cooperate with the cleaning nozzle 12 for cleaning and maintenance.

[0017] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
