Abstract
Description
Technical Field
[0001] This invention relates to the field of freezing and preservation equipment technology, specifically to a freezing and preservation equipment for aquatic products. Background Technology
[0002] In the production and processing of aquatic products (such as shellfish, fish fillets, and raw shrimp), liquid nitrogen flash freezing is usually used to freeze aquatic products in order to quickly lock in freshness and maintain quality. Liquid nitrogen flash freezing can quickly form an ice film, reduce moisture loss, maintain the elasticity and original flavor of the meat, and make the taste closer to the fresh state after thawing. Among them, the liquid nitrogen tunnel freezer is a tunnel-type equipment that uses the ultra-low temperature characteristics of liquid nitrogen to achieve rapid freezing and is widely used in the production and processing of aquatic products. Existing quick-freezing machines typically pre-place aquatic products evenly onto trays before freezing them. These trays are then neatly arranged on a conveyor belt, which transports them into the machine's tunnel for quick-freezing with liquid nitrogen. However, during unloading, the trays containing the frozen aquatic products are usually manually lifted and the products poured out. This prolonged contact between workers and the low-temperature frozen products not only causes physical discomfort but also reduces unloading efficiency due to physical exertion. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the present invention provides a freezing and preservation device for aquatic products to overcome the above-mentioned technical problems existing in the existing related technologies.
[0004] To solve the above technical problems, the present invention provides the following technical solution: a freezing and preservation device for aquatic products, comprising a freezer body, a tilting frame, a clamping assembly, and a beating assembly. A conveyor belt is installed on the freezer body, with a feeding end and a discharging end at both ends of the conveyor belt. The conveyor belt transports a tray containing aquatic products from the feeding end to the discharging end. The tilting frame is rotatably mounted on the discharging end of the conveyor belt. Several tray supports are slidably installed on both sides of the tilting frame, and the tray supports on the same side can slide synchronously along the tilting frame. During unloading, the tilting frame rotates several pallet supports on one side to the unloading end. The pallet supports on that side simultaneously slide out of the tilting frame and move onto the conveyor belt to pick up the pallets. After picking up the pallets, the pallet supports drive the pallets back onto the tilting frame. The tilting frame continues to rotate, tilting the picked-up pallets to pour out the products inside, and rotating several pallet supports on the other side to the unloading end. The clamping assembly includes a fixed clamp plate, which is slidably mounted above the pallet support. When the pallet support extends the fixed clamp plate out of the flip frame, the fixed clamp plate slides upward to open the pallet support. When the pallet support retracts the fixed clamp plate into the flip frame, the fixed clamp plate slides downward to close the pallet support. The tapping component is used to tap the overturned tray, causing the frozen seafood inside the tray to fall out completely.
[0005] Preferably, a support frame is fixedly connected to the main body of the freezer, the support frame is located at the unloading end of the conveyor belt, and a pneumatic slide rail is fixedly connected to the outer side of the support frame.
[0006] Preferably, a rotating shaft is fixedly connected to the middle of the tilting frame, and the rotating shaft is rotatably connected to the inner side of the support frame.

Several spring grooves are provided on both sides of the tray support, and a support spring is provided in each spring groove. The lower end of the support spring is fixedly connected to the bottom of the spring groove. A limit strip is fixedly connected to the closed end of the tray support.
[0008] Preferably, the fixing clamp is also C-shaped, and the fixing clamp fits into the tray support. The open end of the fixing clamp corresponds to the open end of the tray support. Several sliding cylinders are fixedly connected to the bottom of both sides of the fixing clamp. Each sliding cylinder corresponds to a spring groove and is slidably connected in the spring groove. The upper end of the support spring is fixedly connected to the top of the sliding cylinder. Baffles are fixedly connected to both sides of the open end of the fixing clamp. A limit groove is opened on the closed end of the fixing clamp, and the limit strip is slidably connected in the limit groove.
[0009] Preferably, the tilting frame has several cylinder slots, each corresponding to one of the tray supports. The cylinder slots are located between the recycling tank and the rotating shaft. Each cylinder slot has a drive cylinder fixedly installed inside it. The output shaft of the drive cylinder is fixedly connected to the lower part of the closed end of the tray support. The tilting frame is fixedly connected to a mounting frame, and a pressure rod is rotatably connected to the upper end of the mounting frame.
[0010] Preferably, a plurality of guide rails are fixedly connected to the flipping frame, and the plurality of guide rails are all located on the side of the recycling tank near the rotating shaft. Each pair of guide rails corresponds to the two sides of one of the tray supports. A slider is slidably installed on the guide rail, and a secondary connecting seat is fixedly connected to the slider. The secondary connecting seat is located below the pressure rod.
[0011] Preferably, the clamping assembly further includes a main connecting seat and a connecting rod. The main connecting seat is slidably mounted on the top of the fixed clamping plate, one end of the connecting rod is rotatably connected to the main connecting seat, and the other end of the connecting rod is rotatably connected to the auxiliary connecting seat.
[0012] Preferably, the tapping assembly includes a sliding frame, a rotating roller, and a motor. The lower end of the sliding frame is slidably mounted on the pneumatic slide rail, and the upper end of the sliding frame is rotatably connected to the rotating roller. A plurality of soft rubber rods for tapping the tray are fixedly connected to the rotating roller. The plurality of soft rubber rods are evenly distributed in a circumferential shape on the outer side of the rotating roller.

[0013] Preferably, a tray recycling bin and a collection bin are placed sequentially below the flipping frame, and the tray recycling bin and the collection bin are used to collect trays and frozen aquatic products, respectively.
[0014] Compared with the prior art, the present invention provides a freezing and preservation device for aquatic products, which has the following beneficial effects: 1. This aquatic product freezing and preservation device, through the cooperation of a tilting frame, a tray support, and a clamping assembly, allows the tilting frame to turn one side of the tray support towards the unloading end during unloading, extending that side of the tray support onto the conveyor belt. Simultaneously, the fixing plate of the clamping assembly slides upward on the tray support, opening it to receive a row of trays from the conveyor belt. Subsequently, the tray support pulls the trays back onto the tilting frame, and the fixing plate slides downward to clamp and fix the trays. The tilting frame then rotates 180 degrees to flip the trays, emptying the frozen aquatic products from the trays, completing the unloading process. At the same time, the tray support on the other side of the tilting frame takes over from the previous tray support to receive the next row of trays from the conveyor belt. This avoids physical discomfort to workers due to prolonged contact with low-temperature frozen aquatic products and improves the unloading efficiency of aquatic products.
[0015] 2. This aquatic product freezing and preservation device, through the setting of the tapping component, when the flipping frame has not flipped the tray above the collection box, the sliding frame of the tapping component moves away from the flipping frame under the drive of the pneumatic slide rail, leaving enough space for the flipping frame to flip. This allows the flipping frame to drive the tray to complete the flipping after receiving the tray. After the flipping frame flips the tray, the sliding frame moves to above the tray under the drive of the pneumatic slide rail. The rotating roller drives the soft rubber rod to rotate, and the soft rubber rod taps the flipped tray, so that all the frozen aquatic products in the tray can be poured out, avoiding waste caused by incomplete unloading.

Detailed Implementation
[0018] 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.
[0019] Please see Figures 1-12 A freezing and preservation device for aquatic products includes a freezer body 1, a tilting frame 2, a clamping assembly 3, and a beating assembly 4. A conveyor belt 11 is installed on the freezer body 1. The two ends of the conveyor belt 11 are a feeding end 111 and a discharging end 112, respectively. The conveyor belt 11 conveys a tray containing aquatic products from the feeding end 111 to the discharging end 112. The tilting frame 2 is rotatably installed on the discharging end 112 of the conveyor belt 11. Several tray supports 24 are slidably installed on both sides of the tilting frame 2. Several tray supports 24 on the same side can slide synchronously along the tilting frame 2. During unloading, the tilting frame 2 rotates several pallet supports 24 on one side to the unloading end 112. The pallet supports 24 on this side simultaneously slide out of the tilting frame 2 and move to the conveyor belt 11 to pick up the pallet. After picking up the pallet, the pallet supports 24 drive the pallet back to the tilting frame 2. The tilting frame 2 continues to rotate, flipping the picked-up pallet to pour out the product inside, and rotating several pallet supports 24 on the other side to the unloading end 112. The clamping assembly 3 includes a fixed clamping plate 31, which is slidably mounted above the pallet support 24. When the pallet support 24 drives the fixed clamping plate 31 to extend out of the flipping frame 2, the fixed clamping plate 31 slides upward to open the pallet support 24. When the pallet support 24 drives the fixed clamping plate 31 to retract into the flipping frame 2, the fixed clamping plate 31 slides downward to close the pallet support 24. The slapping component 4 is used to slap the overturned tray, causing the frozen seafood inside the tray to fall completely.
[0020] In operation, workers neatly place trays containing aquatic products onto the conveyor belt 11 at the loading end 111, ensuring that the number of trays in each row corresponds to the number of tray supports 24 on one side of the tilting shaft. When the conveyor belt 11 transports the trays into the freezer body 1, the freezer body 1 freezes the aquatic products in the trays. Subsequently, the conveyor belt 11 delivers the frozen aquatic products out of the freezer body 1 and moves towards the unloading end 112. At this time, the tilting frame 2 turns one side towards the unloading end 112 and drives the tray supports 24 to slide towards the conveyor belt 11, extending from the tilting frame 2. The pallet support 24 moves to the conveyor belt 11 at the unloading end 112, so that the bottom of the pallet support 24 is attached to the surface of the conveyor belt 11. At the same time, the fixing plate 31, which was originally closed on the pallet support 24, slides upward, opening the pallet support 24 and creating a gap between the pallet support 24 and the fixing plate 31. Then, the conveyor belt 11 transports a row of pallets containing frozen aquatic products into the opened pallet support 24. The edges of the pallets on both sides slide into the gap between the pallet support 24 and the fixing plate 31. After the pallets are completely inside the pallet support 24, the pallet support 24 on the conveyor belt 11 moves the pallet... The tray moves towards the tilting frame 2 until the tray support 24 is completely detached from the conveyor belt 11 and retracted onto the tilting frame 2. During this process, as the tray support 24 moves, the fixing clamp 31 slides downward, causing the tray support 24 to close. By clamping the edge of the tray, the tray is fixed onto the tray support 24. Subsequently, the tilting frame 2 rotates 180 degrees towards the tapping assembly 4, thereby tilting the clamped tray and emptying the frozen aquatic products from the tray. At the same time, the tilting frame 2 tilts the other side of the tray support 24 toward the unloading end 112. The above steps are repeated to begin receiving the products from the conveyor belt 11. The next row of trays is rotated, and then the flipping frame 2 continues to rotate. During the process of the flipping frame 2 flipping the next row of trays 180 degrees, the tray support 24 carrying the empty tray will extend the flipping frame 2 again when it turns to the unloading end 112, opening the closed fixing plate 31, thereby putting down the clamped empty tray. After putting down the empty tray, the tray support 24 returns to the flipping frame 2, the fixing plate 31 closes again, and turns to the unloading end 112. When pouring out the frozen aquatic products, the tapping component 4 taps the flipped tray to knock off the aquatic products stuck in the tray that could not be poured out.
[0021] Furthermore, a support frame 13 is fixedly connected to the main body 1 of the refrigeration unit. The support frame 13 is located at the unloading end 112 of the conveyor belt 11, and a pneumatic slide rail 131 is fixedly connected to the outside of the support frame 13.
[0022] Furthermore, a rotating shaft 21 is fixedly connected to the middle of the tilting frame 2. The rotating shaft 21 is rotatably connected to the inner side of the support frame 13. The rotating shaft 21 is located at the end of the pneumatic slide rail 131 near the conveyor belt 11. One end of the rotating shaft 21 passes through the support frame 13 and is coaxially fixedly connected to the output shaft of the drive motor 22. The drive motor 22 is fixedly installed on the outer side of the support frame 13. Several recycling troughs 23 are evenly and orderly opened on both sides of the tilting frame 2. The side of the recycling trough 23 away from the rotating shaft 21 is open. Each recycling trough 23 has a fixing plate 231 on both sides, and the fixing plate 231 is fixedly connected to the tilting frame 2.
[0023] When the pallet is flipped, the drive motor 22 drives the flipping frame 2 to rotate through the rotating shaft 21. When the pallet support 24 drives the pallet to retract into the flipping frame 2, the bottom of the pallet is located in the recycling trough 23, thereby further restricting the pallet.
[0024] Furthermore, the pallet support 24 is U-shaped, and the two sides of the pallet support 24 are slidably mounted on the fixed plate 231. The open end of the pallet support 24 is on the same side as the opening of the recycling trough 23. Several spring grooves 241 are provided on both sides of the pallet support 24. Each spring groove 241 is provided with a support spring 242. The lower end of the support spring 242 is fixedly connected to the bottom of the spring groove 241. A limit strip 243 is fixedly connected to the closed end of the pallet support 24.
[0025] Furthermore, the fixing plate 31 is also C-shaped, and the fixing plate 31 fits into the tray support 24. The open end of the fixing plate 31 corresponds to the open end of the tray support 24. Several sliding cylinders 311 are fixedly connected to the bottom of both sides of the fixing plate 31. Each sliding cylinder 311 corresponds to a spring groove 241 and is slidably connected in the spring groove 241. The upper end of the supporting spring 242 is fixedly connected to the top of the sliding cylinder 311. Baffles 312 are fixedly connected to both sides of the open end of the fixing plate 31. A limiting groove 313 is opened on the closed end of the fixing plate 31, and the limiting strip 243 is slidably connected in the limiting groove 313.
[0026] Furthermore, the tilting frame 2 is provided with several cylinder slots 28, each cylinder slot 28 corresponding to a tray support 24. The cylinder slots 28 are located between the recycling tank 23 and the rotating shaft 21. Each cylinder slot 28 is fixedly installed with a drive cylinder 281. The output shaft of the drive cylinder 281 is fixedly connected to the lower part of the closed end of the tray support 24. The tilting frame 2 is fixedly connected with a mounting frame 27, and a pressure rod 271 is rotatably connected to the upper end of the mounting frame 27.
[0027] When the pallet support 24 retracts onto the tilting frame 2, the pressure rod 271 constrains the fixed clamp 31, causing the fixed clamp 31 to close onto the pallet support 24. The baffle 312 is inserted into the recycling trough 23, sealing both sides of the opening ends of the pallet support 24 and the fixed clamp 31. When the pallet enters the pallet support 24, the falling baffle 312 prevents the pallet from sliding out of the opening ends of the pallet support 24 and the fixed clamp 31. The slide cylinder 311 slides towards the bottom of the spring groove 241, thereby compressing the support spring 242. When it is necessary to extend the pallet support 24, the drive cylinder 281 pushes the pallet support 24 through the extended output shaft, causing the pallet support 24 to drive the fixed clamp 31 to slide along the fixed plate 231 in a direction away from the rotating shaft 21. During this process, the fixed clamp 31... When the clamp 31 is released from the constraint of the pressure rod 271, the compressed support spring 242 recovers its deformation, pushing the fixed clamp 31 to slide upward, thereby opening the pallet support 24 and lifting the baffle 312 so that the baffle 312 is above the pallet support 24. The pallet on the conveyor belt 11 can pass under the baffle 312 and slide into the gap between the pallet support 24 and the fixed clamp 31. When it is necessary to retract the pallet support 24, the drive cylinder 281 retracts the output shaft to pull the pallet support 24, so that the pallet support 24 drives the fixed clamp 31 to slide along the fixed plate 231 toward the rotating shaft 21. During this process, the fixed clamp 31 moves closer to the pressure rod 271, and the pressure rod 271 re-constrains the fixed clamp 31, so that the fixed clamp 31 closes on the pallet support 24 again.
[0028] Furthermore, several guide rails 25 are fixedly connected to the flipping frame 2. The guide rails 25 are all located on the side of the recycling tank 23 near the rotating shaft 21. Each pair of guide rails 25 corresponds to the two sides of a tray support 24. A slider 251 is slidably installed on the guide rail 25. A secondary connecting seat 26 is fixedly connected to the slider 251. The secondary connecting seat 26 is located below the pressure rod 271.
[0029] Furthermore, the clamping assembly 3 also includes a main connecting seat 32 and a connecting rod 33. The main connecting seat 32 is slidably mounted on the top of the fixed clamping plate 31, one end of the connecting rod 33 is rotatably connected to the main connecting seat 32, and the other end of the connecting rod 33 is rotatably connected to the auxiliary connecting seat 26.
[0030] When the pallet support 24 retracts onto the tilting frame 2, the fixed clamp 31 pushes the connecting rod 33 towards the rotating shaft 21 via the main connecting seat 32. This causes the connecting rod 33 to push the slider 251 at its other end to slide onto the guide rail 25 near the rotating shaft 21. At this time, the pressure rod 271 presses against the connecting rod 33, causing the connecting rod 33 to push the fixed clamp 31 downward, thus closing it onto the pallet support 24. When the pallet support 24 extends out of the tilting frame 2, the fixed clamp 31 pulls the connecting rod 33 away from the rotating shaft 21 via the main connecting seat 32. This causes the connecting rod 33 to drag the slider 251 at its other end to slide onto the guide rail 25 away from the rotating shaft 21. At one end, the slider 251 passes under the pressure rod 271, causing the connecting rod 33 to disengage from the pressure rod 271, ending the pressure of the pressure rod 271 on the connecting rod 33. This allows the fixed clamping plate 31 to slide upward under the action of the support spring 242, thereby opening the closed tray bracket 24 and lifting the connecting rod 33 upward at a certain angle. When the fixed clamping plate 31 returns to the flipping frame 2, the fixed clamping plate 31 pushes the slider 251 to move towards the rotating shaft 21 through the connecting rod 33. When the slider 251 drives the secondary connecting seat 26 to pass through the bottom of the pressure rod 271 again, the pressure rod 271 abuts against the connecting rod 33 again, pressing the lifted connecting rod 33 downward.
[0031] Furthermore, the tapping assembly 4 includes a sliding frame 41, a rotating roller 42, and a motor 44. The lower end of the sliding frame 41 is slidably mounted on the pneumatic slide rail 131, and the upper end of the sliding frame 41 is rotatably connected to the rotating roller 42. Several soft rubber rods 43 for tapping the tray are fixedly connected to the rotating roller 42. The several soft rubber rods 43 are evenly distributed in a circumferential shape on the outer side of the rotating roller 42. One end of the rotating roller 42 is coaxially fixedly connected to the output shaft of the motor 44, and the motor 44 is fixedly mounted on the sliding frame 41.
[0032] When the flipping frame 2 has not flipped the tray containing frozen aquatic products, the pneumatic slide rail 131 drives the sliding frame 41 to slide away from the flipping frame 2, so that the flipping frame 2 can flip between the conveyor belt 11 and the tapping assembly 4. After the flipping frame 2 flips the tray containing frozen aquatic products 180 degrees, the pneumatic slide rail 131 drives the sliding frame 41 to move closer to the flipping frame 2, so that the rotating roller 42 is above the flipped tray. At the same time, the motor 44 drives the rotating roller 42 to rotate. The rotating roller continuously taps the bottom of the tray through the soft rubber rod 43, so that the aquatic products in the tray can be completely poured out. After all the aquatic products are poured out, the pneumatic slide rail 131 drives the sliding frame 41 away from the flipping frame 2 again.
[0033] Furthermore, a tray recycling bin 5 and a collection bin 6 are placed sequentially below the flipping frame 2. The tray recycling bin 5 and the collection bin 6 are used to collect trays and frozen aquatic products, respectively.
[0034] When the flipping frame 2 flips the tray containing frozen aquatic products 180 degrees, the flipped tray is directly above the collection box 6. The tray pours the frozen aquatic products into the collection box 6. When the flipping frame 2 continues to rotate 90 degrees, the empty tray is above the tray recycling box 5. The tray support 24 carrying the empty tray then extends out of the flipping frame 2 again and puts the empty tray into the tray recycling box 5.
[0035] Working principle: During use, workers neatly place trays containing aquatic products onto the conveyor belt 11 at the loading end 111, ensuring that the number of trays in each row corresponds to the number of tray supports 24 on one side of the tilting shaft. When the conveyor belt 11 transports the trays into the freezer body 1, the freezer body 1 freezes the aquatic products in the trays. Subsequently, the conveyor belt 11 sends the frozen aquatic products out of the freezer body 1 and moves towards the unloading end 112. At this time, the drive motor 22 drives the tilting frame 2 to turn one side towards the unloading end 112 via the rotating shaft 21. The drive cylinder 281 pushes the tray supports 24 to slide towards the conveyor belt 11 via the extended output shaft. The tray supports 24 rotate from the tilting shaft... The tray support 24 extends from the frame 2 and moves to the conveyor belt 11 at the unloading end 112, so that the bottom of the tray support 24 is attached to the surface of the conveyor belt 11. At the same time, the fixed clamp 31 pulls the connecting rod 33 away from the rotating shaft 21 through the main connecting seat 32. The connecting rod 33 then drags the slider 251 at the other end to slide to the end of the guide rail 25 away from the rotating shaft 21. At this time, the slider 251 passes under the pressure rod 271, so that the connecting rod 33 is disengaged from the pressure rod 271, ending the pressure of the pressure rod 271 on the connecting rod 33. The fixed clamp 31 slides upward under the action of the support spring 242, thereby opening the closed tray support 24 and creating a gap between the tray support 24 and the fixed clamp 31. Subsequently, conveyor belt 11 transports a row of pallets containing frozen aquatic products into the open pallet support 24. The edges of the pallets slide into the gap between the pallet support 24 and the fixed clamp 31. After the pallets are fully inside the pallet support 24, the drive cylinder 281 retracts its output shaft, and the pallet support 24 on the conveyor belt 11 moves the pallets toward the tilting frame 2 until the pallet support 24 is completely detached from the conveyor belt 11 and retracts onto the tilting frame 2. During this process, the fixed clamp 31 pushes the connecting rod 33 toward the rotating shaft 21 through the main connecting seat 32, and the slider 251 drives the auxiliary connecting seat 26 to pass through the bottom of the pressure rod 271 again. Then, the pressure rod 271 abuts against the connecting rod 33 again, pressing the lifted connecting rod 33 to move downward, causing the connecting rod 33 to push the fixed clamping plate 31 to slide downward, thereby closing on the pallet support 24, and compressing the support spring 242, which clamps the edge of the pallet, thereby fixing the pallet on the pallet support 24. Subsequently, the drive motor 22 continues to drive the flipping frame 2 to rotate 180 degrees towards the tapping assembly 4, thereby flipping the clamped pallet and pouring out the frozen aquatic products in the pallet. At the same time, the flipping frame 2 turns the other side of the pallet support 24 toward the unloading end 112, repeating the above steps to start receiving the next row of pallets on the conveyor belt 11. Subsequently, the tilting frame 2 continues to rotate. During the process of tilting the next row of pallets 180 degrees, the pallet support 24 carrying the empty pallet extends out of the tilting frame 2 again as it turns to the unloading end 112, opening the closed fixing clamp 31 to release the clamped empty pallet. After releasing the empty pallet, the pallet support 24 retracts back onto the tilting frame 2, the fixing clamp 31 closes again, and it turns to the unloading end 112. Meanwhile, when the tilting frame 2 is not tilting the pallet containing frozen aquatic products, the pneumatic slide rail 131 drives the sliding frame 41 to move away from the tilting frame 2. The directional sliding allows the tilting frame 2 to tilt between the conveyor belt 11 and the tapping assembly 4. After the tilting frame 2 tilts the tray containing frozen aquatic products 180 degrees, the pneumatic slide rail 131 drives the sliding frame 41 to move closer to the tilting frame 2, so that the rotating roller 42 is above the tilted tray. At the same time, the motor 44 drives the rotating roller 42 to rotate. The rotating roller continuously taps the bottom of the tray through the soft rubber rod 43, so that the aquatic products in the tray can be completely poured out. After all the aquatic products are poured out, the pneumatic slide rail 131 drives the sliding frame 41 away from the tilting frame 2 again.
