Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a grading and screening device for frozen shrimp processing. Background Technology

[0002] In the frozen shrimp processing industry, to meet the needs of different consumption scenarios and market demands, frozen shrimp need to be graded according to size. The accuracy and efficiency of grading directly affect product quality and the continuity of subsequent processing steps. Currently, the commonly used grading methods for frozen shrimp in the industry mostly rely on manual screening or simple screening equipment. Manual screening requires workers to compare the size of frozen shrimp one by one, which is not only labor-intensive and time-consuming, but also prone to low grading accuracy due to human judgment errors, making it difficult to adapt to the needs of large-scale production. Simple screening equipment mostly uses screens with fixed apertures for grading. Due to the irregular shape of frozen shrimp, the screens are prone to clogging, and only one size can be screened at a time. Multiple screen replacements are required to complete grading of multiple sizes, which is cumbersome and inefficient. In addition, some screening equipment lacks a stable material conveying and dispersing structure, and frozen shrimp tend to accumulate in certain parts of the equipment after being poured in, further reducing the uniformity of grading. This cannot meet the actual needs of efficient and accurate grading in the frozen shrimp processing process. Therefore, it is necessary to design a grading and screening device for frozen shrimp processing to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a grading and screening device for frozen shrimp processing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A grading and screening device for frozen shrimp processing includes a base, with upright plates fixedly connected to all four sides of the upper end of the base. Sliding grooves are formed on the upper left and upper right sides of the base. A placement groove is formed in the middle of the upper end of the base. Four long boxes are placed on the lower wall of the placement groove. A recess is formed at the rear right end of the base, and a power supply box is fixedly connected to the rear right end of the base, located behind the recess. A component for sorting frozen shrimp by size is slidably connected to the upper end of the base.

[0006] Preferably, the frozen shrimp size sorting component includes two sliders. The upper ends of the two sliders are fixedly connected to a sorting box. A spacer conical roller is fixedly connected between the left and right walls of the sorting box. Multiple spacer conical rollers are provided. A discharge box is fixedly connected to the upper right part of the sorting box. Multiple spacer plates are fixedly connected between the left and right walls of the discharge box. A driving component is fixedly connected to the lower right part of the sorting box. The sliders are slidably connected in the grooves.

[0007] Preferably, the driving component includes a driving motor and a fixing block. The output end of the driving motor passes through the base and is fixedly connected to a turntable. A connecting rod is fixedly connected to the outer surface of the turntable. Springs are fixedly connected to both the front and rear ends of the fixing block. A fixing rod is fixedly connected to the other end of each spring. A connecting block is fixedly connected to the right end of the fixing block on the right side. The driving motor is fixedly connected to the upper groove wall of the groove.

[0008] Preferably, the right end of the fixing block on the left is fixedly connected to the lower left end of the sorting box, and the left end of the fixing block on the right is fixedly connected to the lower right end of the sorting box.

[0009] Preferably, the other end of the fixing rod is fixedly connected to the upright plate, and the connecting rod is movably connected to the connecting block and can drive the connecting block to move back and forth.

[0010] Preferably, the plurality of spacers are equidistantly distributed along the length of the pouring box.

[0011] Preferably, the plurality of spacer conical rollers are arranged with the left side lower than the right side, and the plurality of spacer conical rollers are equally distributed along the width of the sorting box. The plurality of spacer conical rollers have the same tilt angle of 15°, and the gap between the spacer conical rollers gradually decreases from left to right.

[0012] Preferably, the four upright plates are arranged in a rectangular shape, the placement slot is located between two sliding grooves, the four long boxes are arranged horizontally in the placement slot, and the power supply box is electrically connected to the drive motor through a circuit to provide power to the drive motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, through the cooperative relationship between the feeding box and the partition plate, and between the sorting box and the interval conical roller, the feeding box can evenly disperse the frozen shrimp to be screened through the internal partition plate, avoiding the accumulation of frozen shrimp. At the same time, the sorting box can allow the dispersed frozen shrimp to slide along the inclined roller surface through the internal interval conical roller with a left-low and right-high gradient. Frozen shrimp of different sizes fall from the corresponding gaps, realizing accurate grading of multiple specifications, effectively solving the problem of poor grading uniformity of existing equipment.

[0015] 2. In this utility model, through the mutual cooperation between the driving component and the sorting box, the slider and the chute, the driving component can drive the turntable, connecting rod and connecting block to move through the driving motor. With the buffering and reset effect of the spring, the sorting box is driven to slide back and forth stably in the chute through the slider. This movement, combined with the structure of the spaced conical roller, can complete the grading of multiple specifications without replacing the screening components, effectively solving the problem of low grading efficiency of existing equipment.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A grading and screening device for frozen shrimp processing, such as Figure 1-4 As shown, the system includes a base 1, with upright plates 3 fixedly connected to the upper four sides of the base 1. Sliding grooves 8 are opened on the upper left and upper right sides of the base 1. A placement groove 6 is opened in the middle of the upper part of the base 1. A long box 7 is placed on the lower wall of the placement groove 6. Four long boxes 7 are provided. A groove 4 is opened in the rear right part of the base 1. A power box 5 is fixedly connected to the rear right part of the base 1, and the power box 5 is located behind the groove 4. A sorting and freezing shrimp size component 2 is slidably connected to the upper part of the base 1.

[0026] The four upright plates 3 are arranged in a rectangular shape, the placement slot 6 is located between the two sliding slots 8, the four long boxes 7 are arranged horizontally in the placement slot 6, and the power supply box 5 is electrically connected to the drive motor 261 through the line to provide power to the drive motor 261.

[0027] Through the above scheme: In the grading and screening device for frozen shrimp processing, four rectangularly distributed upright plates 3 provide stable support for the entire device, ensuring the stability of the structure during the screening process. The placement trough 6 is designed to be located between two chutes 8, allowing frozen shrimp of different sizes falling from the sorting components to fall accurately into the placement trough 6. At the same time, four long boxes 7 arranged horizontally in the placement trough 6 can respectively receive frozen shrimp of different sizes, realizing graded collection and avoiding mixing of frozen shrimp after screening. The power box 5 is electrically connected to the drive motor 261 through the circuit and provides it with power, ensuring that the drive motor 261 can operate stably and providing a power source for the screening action of the device.

[0028] Please see Figure 3The frozen shrimp size sorting component 2 includes two sliders 25. The upper ends of the two sliders 25 are fixedly connected to a sorting box 21. The left and right walls of the sorting box 21 are fixedly connected to a spacer conical roller 27. Multiple spacer conical rollers 27 are provided. The upper right part of the sorting box 21 is fixedly connected to a feeding box 22. The left and right walls of the feeding box 22 are fixedly connected to multiple spacer plates 23. The lower right part of the sorting box 21 is fixedly connected to a drive component 26. The sliders 25 are slidably connected in the chute 8. The multiple spacer plates 23 are equidistantly distributed along the length of the feeding box 22. The multiple spacer conical rollers 27 are all arranged with the left side lower than the right side. The multiple spacer conical rollers 27 are equidistantly distributed along the width of the sorting box 21. The multiple spacer conical rollers 27 have the same inclination angle of 15°, and the gap between the spacer conical rollers 27 gradually decreases from left to right.

[0029] Through the above scheme: In the frozen shrimp size sorting component 2 of the grading and screening device for frozen shrimp processing, two sliders 25 are slidably connected in the chute 8, which can drive the sorting box 21, which is fixed at the upper end, to slide stably, providing a stable moving path for the sorting box 21 and preventing it from shifting during the screening process. Multiple spaced conical rollers 27 fixed between the left and right walls of the sorting box 21 are all arranged with a left-low and right-high orientation and the same tilt angle of 15°, and are equidistantly distributed along the width of the sorting box 21. At the same time, the gap between the spaced conical rollers 27 gradually decreases from left to right. This structure ensures that the poured-in frozen shrimp... Frozen shrimp can slide along the inclined roller surface under the action of gravity. During the process, frozen shrimp of different sizes will fall from the corresponding gaps according to their own specifications, achieving precise grading and screening. The pouring box 22 fixed on the upper right side of the sorting box 21 makes it convenient for workers to pour in the frozen shrimp to be screened. Moreover, multiple partition plates 23 evenly distributed along the length of the pouring box 22 can evenly disperse the frozen shrimp to be screened, avoiding the accumulation of frozen shrimp during pouring. This ensures that the frozen shrimp entering the sorting box 21 can pass through the spaced conical rollers 27 one by one or in an orderly manner, which greatly improves the efficiency and accuracy of frozen shrimp grading and screening, and meets the grading requirements of frozen shrimp processing.

[0030] Please see Figure 4The driving component 26 includes a driving motor 261 and a fixing block 265. The output end of the driving motor 261 passes through the base 1 and is fixedly connected to a turntable 262. A connecting rod 263 is fixedly connected to the outer surface of the turntable 262. Springs 266 are fixedly connected to both the front and rear ends of the fixing block 265. A fixing rod 267 is fixedly connected to the other end of each spring 266. A connecting block 264 is fixedly connected to the right end of the fixing block 265 on the right side. The driving motor 261 is fixedly connected to the upper groove wall of the groove 4. The right end of the fixing block 265 on the left side is fixedly connected to the lower left end of the sorting box 21. The left end of the fixing block 265 on the right side is fixedly connected to the lower right end of the sorting box 21. The other end of the fixing rod 267 is fixedly connected to the upright plate 3. The connecting rod 263 is movably connected to the connecting block 264 and can drive the connecting block 264 to move back and forth.

[0031] Through the above scheme: In the drive component 26 of the grading and screening device for frozen shrimp processing, the drive motor 261 is fixedly connected to the upper wall of the groove 4, and its output end passes through the base 1 and is fixedly connected to the turntable 262. When the drive motor 261 runs, it can drive the turntable 262 to rotate. The connecting rod 263 fixed on the outer surface of the turntable 262 rotates with the turntable 262. Because the connecting rod 263 is movably connected to the connecting block 264 fixed at the right end of the right fixed block 265, it can drive the connecting block 264 to move back and forth. The right end of the left fixed block 265 is fixed to the lower left end of the sorting box 21, and the left end of the right fixed block 265 is fixed to the lower right end of the sorting box 21, so that the connection... The forward and backward movement of block 264 can drive the two fixed blocks 265 and the sorting box 21 to move forward and backward synchronously. The other end of the spring 266 fixed at the front and rear ends of the fixed block 265 is inserted and fixed on the fixed rod 267 fixedly connected to the upright plate 3. The spring 266 can play a buffering and resetting role when the sorting box 21 moves forward and backward, avoiding structural damage caused by excessive impact force when the sorting box 21 moves, and ensuring the smoothness of the movement of the sorting box 21. This solution provides stable and controllable forward and backward movement power for the sorting box 21 through the cooperation of the various structures of the drive component 26, ensuring that the interval conical roller 27 can efficiently screen frozen shrimp and improve the stability of the screening process.

[0032] It should be noted that this utility model is a grading and screening device for frozen shrimp processing. The power supply box 5 supplies power to the drive motor 261. The drive motor 261 drives the turntable 262 to rotate, causing the connecting rod 263 to drive the connecting block 264 to move back and forth. Then, with the cooperation of the fixed block 265, the spring 266 and the fixed rod 267, the sorting box 21 slides back and forth in the slide groove 8 through the slider 25. The frozen shrimp are poured into the feeding box 22, dispersed by the partition plate 23 and enter the sorting box 21. Under the sliding action of the sorting box 21 and the action of multiple spaced conical rollers 27 with a left-low and right-high tilt angle of 15° and a gap that gradually decreases from left to right, frozen shrimp of different sizes will fall from the gaps of the corresponding spaced conical rollers 27 and fall into the four long boxes 7 arranged horizontally in sequence in the placement groove 6, realizing the grading and screening of frozen shrimp. The upright plate 3 plays a supporting role for the overall structure.
