DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1: According to Figure 1-Figure 5 As shown, a sorting conveyor for packaging aquatic products comprises a conveyor platform 1, on which mounting brackets 2 are symmetrically arranged, on which a sorting conveying mechanism 3 for sorting aquatic products by size is movably mounted, a continuous feeding mechanism 4 for removing moisture from the surface of the aquatic products is arranged above the sorting conveying mechanism 3, a sorting auxiliary mechanism 5 for marking the aquatic products to avoid confusion is arranged on the mounting bracket 2, a spray cleaning mechanism 6 is arranged between the two mounting brackets 2, and a circulating material receiving mechanism 7 is arranged on the conveyor platform 1. When the aquatic products are packaged and sorted, first, the aquatic products will intermittently fall onto the sorting conveying mechanism 3 under the action of the continuous feeding mechanism 4, and then the sorting conveying mechanism 3 will sort the aquatic products according to their weight, and during the sorting process, the sorting auxiliary mechanism 5 will automatically leave color marks on the surface of the aquatic products.

[0040] Specifically, the sorting and conveying mechanism 3 includes a weight sensor 301 fixedly installed between two mounting brackets 2, feeding components 302 are symmetrically arranged on both sides of the weight sensor 301, and a guide lever 303 is symmetrically arranged above the feeding component 302. A push spring is arranged between the guide lever 303 and the mounting bracket 2. When the aquatic product moves horizontally under the action of the feeding component 302, it will enter from the middle of the conveyor belt 304 under the guidance of the guide lever 303. The conveyor belt 304 is movably installed on the mounting bracket 2, and a discharge notch 305 is respectively opened on the two mounting brackets 2. A discharge inclined plate 306 is fixedly installed on the discharge notch 305. A mounting seat 307 is fixedly installed on the upper end of the mounting bracket 2, and a movably mounted mounting seat 307 is arranged on the mounting seat 307. Equipped with a dividing component 308, after the aquatic product falls onto the feeding component 302, first, the weight sensor 301 will weigh the aquatic product. After the weighing is completed, the feeding component 302 will transport the aquatic product to the conveyor belt 304. Next, the aquatic product that moves synchronously with the conveyor belt 304 will slide down from the corresponding unloading inclined plate 306 under the action of the dividing component 308. The dividing component 308 includes a dividing rod rotatably connected to the mounting seat 307. A driving motor for driving the dividing rod is fixedly installed on the mounting seat 307. After the weighing is completed, the driving motor will automatically be powered on and operated under the action of the controller. Subsequently, the dividing rod will rotate to the middle of the conveyor belt 304, thereby guiding the moving aquatic product to fall through the unloading inclined plate 306.

[0041] In this embodiment, during the aquatic product sorting operation, first, the aquatic product will fall onto the feeding assembly 302 under the action of the continuous feeding mechanism 4, then the weight sensor 301 will measure the weight of the aquatic product and transmit the measured data to the controller (not shown in the figure), then the drive motor will automatically power on and operate under the program control of the controller.

[0042] If the weight of the aquatic product is large and reaches the weight range corresponding to the special-grade product, the driving motor closer to the feeding component 302 will be automatically powered on and operated, and then the dividing lever closer to the feeding component 302 will rotate toward the middle of the conveyor belt 304.

[0043] If the weight of the aquatic product is moderate and reaches the weight range corresponding to the first-level product, then the driving motor farther away from the feeding component 302 will be automatically powered on and operated, and then the dividing rod farther away from the feeding component 302 will rotate toward the middle of the conveyor belt 304.

[0044] If the weight of the aquatic product is small and it is an inferior product, then the two material dividing levers will not rotate toward the middle of the conveyor belt 304.

[0045] Next, the feeding component 302 will horizontally convey the weighed aquatic products until they move to the top of the conveyor belt 304. Next, the aquatic products will move synchronously with the conveyor belt 304. During the movement, if there is a dividing rod located in the middle of the conveyor belt 304, the aquatic products will be discharged through the corresponding unloading inclined plate 306 under the guidance of the dividing rod. If there is no dividing rod located in the middle of the conveyor belt 304, the aquatic products will continue to move with the conveyor belt 304 until they move to the end of the conveyor belt 304 and then fall downwards, thereby completing the sorting operation of the aquatic products.

[0046] Moreover, during horizontal conveying, Figure 3 As shown, the aquatic product will be located in the middle of the conveyor belt 304 under the guidance of the two material guide rods 303, preventing the aquatic product from moving to the edge of the conveyor belt 304 and affecting the work of the material distribution rods.

[0047] This embodiment, by setting up a sorting and conveying mechanism 3 and utilizing the mutual cooperation between the weight sensor 301 and the material separation component 308, can automatically grade and sort the aquatic products according to their weight, which is convenient for subsequent packaging operations and eliminates the need for manual sorting by staff, thereby greatly improving the work efficiency and accuracy of aquatic product sorting operations; moreover, this embodiment, by setting up a sorting and conveying mechanism 3 and utilizing the mutual cooperation between the feeding component 302 and the guide rod 303, can automatically correct and guide the position of the aquatic products during horizontal conveying, so that the aquatic products are located in the middle of the conveyor belt 304, preventing the aquatic products from being located at the edge of the conveyor belt 304 and causing an adverse effect on the work of the material separation rod, thereby providing convenience for subsequent sorting processing.

[0048] Embodiment 2: If the staff manually places the aquatic products on the feeding assembly 302 for weighing, it will lead to low efficiency and cannot ensure the accuracy of weighing. In order to solve this technical defect in the prior art, Figure 1 , Figure 2 as well as Figure 6-Figure 8As shown, on the basis of the first embodiment, the present embodiment is provided with a continuous feeding mechanism 4, specifically, the continuous feeding mechanism 4 comprises a telescopic support rod 401 fixedly mounted on the mounting bracket 2, a rectangular box 402 is fixedly mounted on the telescopic support rod 401, drying fans 403 are symmetrically arranged on both sides of the rectangular box 402, a feed cover plate 404 is detachably mounted on the upper end of the rectangular box 402, a feed channel is penetrated through the feed cover plate 404, two groups of transmission circular shafts 405 are symmetrically arranged inside the rectangular box 402, each group of transmission circular shafts 405 is provided with a transmission belt 406, and a plurality of rectangular shafts 406 are evenly spaced on the transmission belt 406. shaped protrusion 407, the outside of the transmission belt 406 and the rectangular protrusion 407 are wrapped with absorbent cotton cloth 408, and an exhaust circular hole 409 is opened on the inner wall of the rectangular box 402. After the staff puts the aquatic product into the rectangular box 402, the aquatic product will be located above the rectangular protrusion 407. Next, the transmission belt 406 will move downward under the action of the transmission circular shaft 405, thereby transporting the aquatic product downward, and the drying fan 403 is connected with the exhaust circular hole 409. A conveying cavity is formed between the two adjacent groups of rectangular protrusions 407. When the two groups of transmission circular shafts 405 rotate synchronously, the aquatic product will be located inside the conveying cavity and transported downward.

[0049] In this embodiment, Figure 7 As shown, a plurality of symmetrically arranged rectangular protrusions 407 will form a plurality of independent conveying cavities inside the rectangular box 402. When in use, the staff will sequentially place a plurality of aquatic products into the interior of the rectangular box 402 through the feed channel. At the same time, the transmission belt 406 will intermittently move downward under the action of the transmission circular shaft 405, so that the aquatic products are located inside the conveying cavity and move downward synchronously.

[0050] When the aquatic product moves to the lower end of the transmission belt 406, it will fall downward from the lower end of the rectangular box 402, thereby completing automatic discharge. There is no need for the staff to manually place the aquatic products one by one on the top of the weight sensor 301 for weighing. Through the cyclic movement of multiple rectangular protrusions 407, the discharge and feeding can be carried out synchronously without stopping and waiting, thus achieving continuous operation.

[0051] Moreover, before the discharge operation, the staff can adjust the height of the rectangular box 402 according to the volume of the aquatic products. When the telescopic support rod 401 is extended upward, the rectangular box 402 will move upward synchronously. When the telescopic support rod 401 is retracted downward, the rectangular box 402 will move downward, so that the distance between the bottom of the rectangular box 402 and the feeding assembly 302 is appropriate, which can avoid the aquatic products from bouncing up again due to inertia after falling due to excessive spacing, and avoid the movement of the aquatic products from being hindered due to too small spacing.

[0052] In addition, since the outside of the transmission belt 406 and the rectangular protrusion 407 are wrapped with absorbent cotton cloth 408, when the aquatic product is located inside the conveying cavity and moves downward, the surface will contact the absorbent cotton cloth 408, thereby removing part of the moisture on the surface of the aquatic product, which can effectively ensure the accuracy of weighing.

[0053] Moreover, if Figure 7 As shown, the drying fan 403 will continue to blow air outward through the multiple exhaust circular holes 409. Therefore, during the circular movement of the transmission belt 406 and the rectangular protrusion 407, the absorbent cotton cloth 408 can be automatically and quickly dried, thereby ensuring the water absorption capacity of the absorbent cotton cloth 408.

[0054] In this embodiment, by setting up a continuous feeding mechanism 4, the mutual cooperation between the transmission circular shaft 405 and the transmission belt 406 can be used to make the discharge and feeding proceed simultaneously, thus realizing continuous feeding without stopping for waiting, and effectively improving the efficiency of aquatic product sorting. Moreover, the distance between the rectangular box 402 and the feeding assembly 302 can be freely adjusted according to the volume of the aquatic product, which can avoid the aquatic product from bouncing up again due to inertia after falling due to too large a distance, and can also avoid the aquatic product from being obstructed due to too small a distance. In addition, in this embodiment, by setting up a continuous feeding mechanism 4, the aquatic product can be discharged and fed at the same time, and the feeding and feeding of the aquatic product can be carried out at the same time. Mechanism 4, by utilizing the mutual cooperation between the rectangular protrusion 407 and the absorbent cotton cloth 408, can automatically absorb water and dry the surface of the aquatic product in the process of conveying the aquatic product downward, thereby removing most of the moisture on the surface of the aquatic product, which can effectively improve the accuracy of weighing and sorting operations; moreover, this embodiment, by setting up a continuous feeding mechanism 4, utilizes the mutual cooperation between the drying fan 403 and the exhaust circular hole 409, and can automatically blow dry the absorbent cotton cloth 408 in the process of the circulating movement of the transmission belt 406, thereby maintaining the water absorption capacity of the absorbent cotton cloth 408.

[0055] Embodiment 3: According to Figure 1 , Figure 2 , Fig. 9 as well as Fig.10As shown, on the basis of the above embodiments, in order to improve the distinction between different grades of aquatic products as much as possible, the present embodiment is provided with a sorting auxiliary mechanism 5. Specifically, the sorting auxiliary mechanism 5 includes a sorting baffle 501 fixedly mounted on the sorting lever for guiding the aquatic products, a rectangular cotton block 502 is detachably mounted on one side of the sorting baffle 501, a mounting protrusion 503 is fixedly mounted on the other side of the sorting baffle 501, a liquid storage box 504 for soaking the rectangular cotton block 502 is fixedly mounted on the mounting protrusion 503, the liquid storage box 504 is filled with food dye, and the two liquid storage boxes 504 are respectively filled with food dyes of different colors, when the sorting baffle 501 guides the aquatic products to be discharged downward through the discharge inclined plate 306, the aquatic products will contact with the rectangular cotton block 502, and during the contact process, the food dye will adhere to the surface of the aquatic products, thereby distinguishing the special products, the first-grade products and the inferior products.

[0056] In this embodiment, according to the above content, it can be known that when aquatic products of different sizes and grades move on the conveyor belt 304, there will be corresponding material dividing rods to guide and discharge them. During the guiding process, since there is always sliding friction between the conveyor belt 304 and the aquatic products, the aquatic products will cause a certain amount of squeezing on the rectangular cotton block 502, and the interior of the rectangular cotton block 502 is soaked with food coloring agent, so a certain color mark will be formed on the surface of the aquatic products.

[0057] Moreover, the two liquid storage boxes 504 are respectively filled with food dyes of different colors, so the surfaces of the special-grade products and the first-grade products will be printed with marks of different colors, while the surfaces of the inferior products will have no marks, thereby helping the staff to distinguish the aquatic products.

[0058] This embodiment provides a sorting auxiliary mechanism 5 and utilizes the cooperation between the material dividing baffle 501 and the rectangular cotton block 502 to automatically leave different color marks on the surface of the special-grade product and the first-grade product during the grading and sorting process, thereby improving the recognition between different grades of aquatic products and helping staff to quickly distinguish different grades of aquatic products in the subsequent packaging process to avoid confusion.

[0059] Embodiment 4: According to Figure 2 , Figure 4 as well as Fig.11As shown, on the basis of the above embodiment, in order to prevent the residual food dye on the conveyor belt 304 from being contaminated on the aquatic products and causing confusion in the markings, a spray cleaning mechanism 6 is provided in this embodiment. Specifically, the spray cleaning mechanism 6 includes a dirt collecting box 601 arranged below the conveyor belt 304, and a drainage pump body 602 is fixedly installed inside the dirt collecting box 601. A liquid storage cavity is opened inside the conveyor platform 1, and the liquid storage cavity is filled with cleaning liquid. The liquid outlet end of the drainage pump body 602 is connected to a spray assembly 603, and an inclined scraper 604 is detachably installed on the dirt collecting box 601. When the drainage pump body 602 is powered on, the cleaning liquid in the liquid storage cavity is sprayed obliquely upward through the spray assembly 603, thereby spraying and flushing the conveyor belt 304.

[0060] In this embodiment, Figure 4 As shown, during the aquatic product sorting process, the cleaning liquid in the liquid storage cavity will be sprayed obliquely upward through the liquid spray component 603 under the action of the drainage pump body 602. After being sprayed, the cleaning liquid will contact the conveyor belt 304, thereby dissolving the food coloring agent that may fall on the conveyor belt 304, and preventing the residual food coloring agent on the conveyor belt 304 from being contaminated on the aquatic products and causing chaos.

[0061] At the same time, the inclined scraper 604 will scrape off the sewage generated during the dissolution process and make it fall into the interior of the sewage collecting box 601, thereby ensuring that the conveyor belt 304 is in a clean state.

[0062] This embodiment provides a spray cleaning mechanism 6, and utilizes the cooperation between the liquid spray component 603 and the inclined scraper 604 to automatically dissolve and remove the food coloring agent that has fallen onto the conveyor belt 304, thereby preventing the residual food coloring agent on the conveyor belt 304 from being contaminated on the aquatic products and causing confusion in the markings, and can effectively improve the accuracy of grading and sorting.

[0063] Embodiment 5: According to Figure 1 , Figure 2 , Figure 3 as well as Fig.12As shown, on the basis of the above embodiment, in order to facilitate rapid material collection, the present embodiment is provided with a circulating material collection mechanism 7. Specifically, the circulating material collection mechanism 7 comprises a rectangular chute 701 provided on the conveyor platform 1, a sliding base 702 is movably mounted on the rectangular chute 701, a driving screw rod 703 for horizontally moving the sliding base 702 is rotatably connected inside the rectangular chute 701, a first material storage box 704 and a second material storage box 705 are symmetrically arranged on the sliding base 702, and the first material storage box 704 and the second material storage box 705 are symmetrically arranged on the sliding base 702. The inside of the material box 705 is respectively provided with an elliptical cavity 706, and biological ice cubes are placed inside the elliptical cavity 706, which can keep the aquatic products fresh during the material receiving process to prevent the aquatic products from spoiling. The mounting bracket 2 is provided with a side wall slide groove 707, and a third material storage box 708 is movably installed between the two side wall slide grooves 707. When the driving screw rod 703 rotates around its own axis, the sliding base 702 will move horizontally. When the sliding base 702 moves, the first material storage box 704 and the second material storage box 705 will move synchronously.

[0064] In this embodiment, Figure 3 As shown, a first storage box 704 and a second storage box 705 are provided below the two unloading inclined plates 306 . Therefore, after the aquatic products fall downward through the unloading inclined plates 306 , they will enter the interior of the first storage box 704 or the second storage box 705 .

[0065] When the first storage box 704 is full, the sliding base 702 will move horizontally under the action of the driving screw rod 703, thereby removing the first storage box 704 and moving the second storage box 705 to the bottom of the unloading inclined plate 306. Next, the staff will pour out the aquatic products inside the first storage box 704. When the second storage box 705 is full, the sliding base 702 will move horizontally under the action of the driving screw rod 703, thereby removing the second storage box 705 and moving the first storage box 704 to the bottom of the unloading inclined plate 306. Next, the staff will pour out the aquatic products inside the second storage box 705, thereby realizing the circulation of materials.

[0066] This embodiment provides a circulating material receiving mechanism 7, and utilizes the mutual cooperation between the sliding base 702 and the driving screw 703 to automatically complete the alternating replacement between the first material storage box 704 and the second material storage box 705, thereby realizing circulating material receiving without the need to frequently replace the material storage box. Moreover, biological ice cubes are placed inside the elliptical cavity 706, which can play a certain role in preserving the aquatic products and preventing the aquatic products from deteriorating.
