Description

Technical Field

[0001] This invention relates to the field of quick-freezing equipment technology, specifically a drying-type quick-freezing machine for quick-freezing fish products. Background Technology

[0002] Meanwhile, traditional quick-freezing equipment mostly uses a horizontal straight conveying structure, which results in a large overall footprint, low space utilization, and fixed material placement inside the equipment. Due to the limited coverage area of ​​the cold air, the cold air can only act on one side of the material, leading to a long freezing period. Furthermore, the contact area between the material and the conveying surface is prone to freezing and sticking due to the lack of cold air in the closed environment, making it difficult to achieve uniform quick-freezing of the entire surface of the material. During discharge, freezing and sticking can also cause product jamming, damage, and residual material. Summary of the Invention

[0003] The purpose of this invention is to provide a drying-type quick-freezing machine for quick-freezing fish products, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drying-type quick-freezing machine for quick-freezing fish products, comprising a quick-freezing chamber, a feeding conveying mechanism, and a discharging conveying mechanism; the upper part of one side of the quick-freezing chamber is connected to a feeding port that connects to the feeding conveying mechanism, and the lower part of the other side is connected to a discharging port that connects to the discharging conveying mechanism, thereby creating a height difference between the feeding conveying mechanism and the discharging conveying mechanism; The quick-freezing chamber is equipped with a quick-freezing device and a vertical loop conveyor on the front and rear sides respectively. The vertical loop conveyor includes a fixed base plate and a guide limiting member arranged vertically. A long waist-shaped through groove is opened in the middle of the fixed base plate. The guide limiting member is suspended inside the through groove by a bracket. The two form a conveying channel at intervals. The side end of the long waist-shaped through groove is equipped with a driving component, and the side end of the guide limiting component is provided with a guide groove. Several slides that move along the conveying channel are connected between the guide groove and the driving component. A clamping component is provided on the slide. The clamping component moves in a loop as driven by the driving component. The quick-freezing device is arranged along its conveying path to perform quick-freezing operation on the products on the conveying track. The clamping component includes a base and a drive assembly. Several clamping plates are hinged to each side of the base. The drive assembly drives all the clamping plates to open and close synchronously. After all the clamping plates are closed, a receiving space is formed inside. This receiving space is larger than the size of the product. When the clamping plates are at the feeding station, they close to receive the product. During the loop conveying process, the product rolls and flips in the receiving space due to gravity. When the product reaches the discharge station, the clamping plates open, and the product falls to the discharge conveying mechanism by its own weight.

[0005] Furthermore, the driving assembly includes an annular drive frame, which is mounted on the rear end of the fixed base plate. An annular channel is formed at the front end of the annular drive frame, located behind the conveying channel. The tail end of the clamping plate has an L-shaped structure, and a rotating shaft and a waist-shaped hole are sequentially arranged at the tail end of the clamping plate. The rotating shaft is rotatably connected to the base. The base is embedded in the slide block, and a guide rod is provided at the rear end of the base. A guide sleeve is slidably mounted on the guide rod. A return spring is connected between the guide sleeve and the guide rod. The rear end is equipped with a guide wheel located within an annular channel. The annular channel, located in the bottom path section from the discharge station to the feed station, has a raised guide strip, and both ends of the guide strip are connected to the bottom of the annular channel with a beveled transition. The front end of the guide sleeve is hinged with several drive rods corresponding to the clamping plates, and the other end of the drive rod extends through and is hinged to the waist-shaped hole of the clamping plate. Thus, when it moves to the guide strip, the squeeze guide wheel drives the guide sleeve forward, and through the drive rod, it links the waist-shaped hole at the tail of the clamping plate to realize the automatic opening of multiple sets of clamping plates.

[0006] Furthermore, the middle part of the clamping plate is convex and arc-shaped, the front end of the clamping plate is bent inward and formed, and a through hole is opened on the clamping plate.

[0007] Furthermore, the base is rotatably embedded in the middle of the slide, and a gear is sleeved on the outer wall of the base; a corresponding rack is provided on the left side of the guide limiting member.

[0008] Furthermore, a support plate is provided at the bottom end of the feed inlet to receive the product fed by the feeding conveyor mechanism, and the support plate has several clamping openings corresponding to the clamping plate on the lower side of the base. A gap is left between the support plate and the conveying channel to allow the clamping components in the open state to pass through; the guide strip extends to the support plate.

[0009] Furthermore, the quick-freezing device includes a main quick-freezing mechanism and an auxiliary quick-freezing mechanism. The main quick-freezing mechanism is fixedly installed in the middle of the front end of the quick-freezing chamber and located on the inner side of the conveying channel. The auxiliary quick-freezing mechanism is arranged on the upper and left sides of the front end of the quick-freezing chamber and located on the outer side of the conveying channel.

[0010] Furthermore, a cleaning mechanism is provided in the area from the discharge station to the feed station at the front end of the quick-freezing chamber. The cleaning mechanism includes a cleaning plate and a power motor. The cleaning plate is rotatably mounted in the front end of the quick-freezing chamber and is connected to the power motor for transmission. Several flexible cleaning strips are provided at one end of the cleaning plate near the vertical loop conveyor. A chip collection trough is provided below the cleaning mechanism. The chip collection trough can be detachably installed at the bottom of the quick-freezing chamber.

[0011] Furthermore, both the inlet and outlet extend outwards, and anti-leakage cold strips are installed on the outer side of the ports, which respectively constitute the pre-cooling section of the feeding conveying mechanism and the cold preservation section of the discharging conveying mechanism.

[0012] Furthermore, both the feeding conveyor and the discharging conveyor adopt a conveyor belt structure, and several drying fans are installed above the feeding conveyor; the driving component is a chain conveyor.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention features a compact and rationally designed structure. It employs a vertical loop conveyor with a clamping plate structure, allowing materials to tumble naturally within the containment space due to their own weight. Simultaneously, the base is equipped with gears and racks that mesh to drive the material's rotation. The material's revolution, rotation, and gravity-induced tumbling combine to ensure that all surfaces are fully exposed to the freezing air, eliminating defects such as incomplete freezing and uneven freezing thickness. This significantly improves the quick-freezing efficiency and the consistency of the finished frozen product. The unloading station relies on the linkage between the guide strip and the spring to automatically open the clamping plate. After the product is completely freed from the clamping constraint, it falls freely by its own weight. This breaks the static state of the product sticking to the clamping plate and avoids the product freezing and sticking to the inner wall of the clamping plate at low temperature. Structurally, this avoids problems such as material hanging, jamming, and product tearing and damage. This invention relies on a mechanical linkage structure composed of an annular channel, guide strips, and a return spring. Without additional power, the clamps automatically gather and pick up materials at the feeding station and automatically open and unload materials at the discharging station. The entire process requires no manual assistance for feeding and unloading, has a high degree of automation, and is suitable for continuous mass production operations on assembly lines.

[0014] The discharge and return paths are equipped with a cleaning mechanism with flexible cleaning strips, which can dynamically clean the debris and frost adhering to the surface of the clamping plate during equipment operation. Impurities fall into the detachable chip collection trough for centralized collection, eliminating the need for frequent machine shutdowns and disassembly for cleaning, effectively extending the continuous operating time of the equipment and reducing equipment maintenance time.

Detailed Implementation

[0017] 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.

[0018] like Figures 1 to 6 As shown, a quick-freezing dryer for quick-freezing fish products includes a quick-freezing chamber 1, a feeding conveying mechanism 2, and a discharging conveying mechanism 3; the upper part of one side of the quick-freezing chamber 1 is connected to a feeding port 4 that is connected to the feeding conveying mechanism 2, and the lower part of the other side is connected to a discharging port 5 that is connected to the discharging conveying mechanism 3, so that the feeding conveying mechanism 2 and the discharging conveying mechanism 3 have a height difference. The quick-freezing chamber 1 is equipped with a quick-freezing device and a vertical loop conveying device on the front and rear sides respectively. The vertical loop conveying device includes a fixed base plate 6 and a guide limiting member 7 arranged vertically. The fixed base plate 6 has an elongated through groove in the middle. The guide limiting member 7 is suspended inside the through groove by a bracket 30. The two are spaced apart to form a conveying channel 8. The side end of the elongated through groove is fitted with a driving component, and the side end of the guide limiting component 7 is provided with a guide groove. Several slides 9 that move along the conveying channel 8 are connected between the guide groove and the driving component. A clamping component 10 is provided on the slide 9. The clamping component 10 moves in a loop as driven by the driving component, and the quick-freezing device is arranged along its conveying path to perform quick-freezing operation on the products on the conveying track. The clamping component 10 includes a base 11 and a drive assembly. Several clamping plates 12 are hinged to each side of the base 11. The drive assembly drives all the clamping plates 12 to open and close synchronously. After all the clamping plates 12 are closed, they form an internal accommodating space. This accommodating space is larger than the size of the product. When the clamping plates 12 are at the feeding station, they close to receive the product. During the back-shaped conveying process, the product rolls and flips within the accommodating space due to gravity. When the product reaches the discharge station, the clamping plates 12 open, and the product falls to the discharge conveying mechanism 3 by its own weight.

[0019] In this embodiment, the driving assembly includes an annular drive frame 13, which is mounted on the rear end of the fixed base plate 6. An annular channel 14 is provided at the front end of the annular drive frame 13, located behind the conveying channel 8. The tail of the clamping plate 12 has an L-shaped structure, and a rotating shaft and a waist-shaped hole are sequentially provided at the tail end of the clamping plate 12. The rotating shaft is rotatably connected to the base 11. The base 11 is embedded in the slide block 9, and a guide rod 15 is provided at the rear end of the base 11. A guide sleeve 16 is slidably mounted on the guide rod 15. A return spring 17 is connected between the guide sleeve 16 and the guide rod 15. The rear end of the 6 is provided with a guide wheel 18, which is located in the annular channel 14. The annular channel 14 is located in the bottom path section from the discharge station to the feed station and is provided with a protruding guide strip 19. Both ends of the guide strip 19 are connected to the bottom of the annular channel 14 with a bevel transition. The front end of the guide sleeve 16 is hinged with several drive rods 20 corresponding to the clamping plate 12. The other end of the drive rod 20 extends through and is hinged to the waist-shaped hole of the clamping plate 12. Thus, when it moves to the guide strip 19, the squeeze guide wheel 18 drives the guide sleeve 16 to move forward, and through the drive rod 20, it links the waist-shaped hole at the tail of the clamping plate 12 to realize the automatic opening of multiple sets of clamping plates 12. When the clamping component 10 moves with the slide 9 to the area of ​​the guide bar 19, the guide wheel 18 is squeezed forward by the guide bar 19, which drives the guide sleeve 16 to compress the return spring 17 and move forward synchronously. Through the drive rod 20, the tail of the clamping plate 12 is pushed. Using the stroke margin of the waist-shaped hole, all clamping plates 12 are driven to rotate around the rotating shaft, thus opening synchronously. When the clamping component 10 leaves the area of ​​the guide bar 19, the return spring 17 rebounds and drives the guide sleeve 16 to reset, pulling the clamping plates 12 to close synchronously, realizing the automatic opening and closing cycle of the clamping plates 12.

[0020] In this embodiment, a support plate 22 is provided at the bottom end of the feed port 4 to receive the product fed by the feeding conveyor mechanism 2. The support plate 22 is provided with a plurality of clamping openings 23 corresponding to the clamping plate 12 on the lower side of the base 11. A gap is left between the support plate 22 and the conveying channel 8 to allow the clamping component 10 in the open state to pass through. The guide strip 19 extends to the support plate 22.

[0021] During feeding, the feeding conveyor 2 transports the fish products to the end and they slide onto the support plate 22. The clamping component 10, which is in an open state, moves along the conveying trajectory. It first passes through the gap between the support plate 22 and the conveying channel 8, allowing the upper and left and right clamping plates 12 to pass through the area above the support plate 22. At this time, after the guide wheel 18 is released from the squeezing constraint of the guide bar 19, all the clamping plates 12 begin to close synchronously. During the rotation and closing process, the lower clamping plate 12 passes through the clamping opening 23 of the support plate 22. Through the closing and rotating action of the lower clamping plate 12, the fish products on the support plate 22 are lifted up to the lower clamping plate 12. Finally, the multiple sets of clamping plates 12 are completely closed, storing the products in the enclosed space, completing the stable automatic feeding process.

[0022] In this embodiment, the middle part of the clamping plate 12 is convex and arc-shaped, and the front end of the clamping plate 12 is bent inward. The clamping plate 12 is provided with through holes. The arc-shaped convex part of the middle part of the clamping plate 12 structure can effectively expand the accommodating space enclosed by the clamping plate 12 to meet the product flipping requirements. The inward bending of the front end can form a limiting structure to prevent the product from accidentally slipping out during the conveying and flipping process, and also to facilitate the retrieval of the product when loading.

[0023] In this embodiment, the quick-freezing device includes a main quick-freezing mechanism 24 and an auxiliary quick-freezing mechanism 25. The main quick-freezing mechanism 24 is fixedly installed in the middle of the front end of the quick-freezing chamber 1 and is located inside the conveying channel 8. The auxiliary quick-freezing mechanism 25 is arranged on the upper and left sides of the front end of the quick-freezing chamber 1 and is located outside the conveying channel 8. The base 11 is rotatably embedded in the middle of the slide 9, and the outer wall of the base 11 is fitted with a gear 21. A corresponding rack is provided on the left side of the guide limiting member 7.

[0024] like Figure 6 As shown, the main quick-freezing mechanism 24 has a cylindrical structure with cold air outlets distributed around it, quickly freezing fish products on the conveying track at close range. The auxiliary quick-freezing mechanism 25 is arranged on the upper and left sides of the front end of the quick-freezing chamber 1, covering the outer area of ​​the conveying channel 8 and compensating for the edge cooling blind spots of the cylindrical main quick-freezing mechanism 24. The rack is located between the main quick-freezing mechanism 24 and the auxiliary quick-freezing mechanism 25. When the drive component moves the slide 9 to the rack, the gear 21 continuously meshes with the rack, driving the base 11 and the clamp. The product rotates at a constant speed, and the rotating and tumbling conveyor, along with the circular conveyor's orbital trajectory, allows the fish to come into contact with the low-temperature cold air from all directions—up, down, front, back, left, and right—to quickly achieve low-temperature freezing. At the same time, the continuous rotation of the product effectively prevents the fish from sticking to the surface of the clamping plate 12 after freezing, breaking the static state of the product and the clamping plate 12 and eliminating the possibility of freezing and sticking. This ensures that when the product arrives at the discharge station and the clamping plate 12 opens, it can fall smoothly by its own weight, ensuring smooth discharge without jamming or residue.

[0025] In this embodiment, a cleaning mechanism is provided in the area from the discharge station to the feed station at the front end of the quick-freezing chamber 1. The cleaning mechanism includes a cleaning plate 26 and a power motor. The cleaning plate 26 is rotatably mounted in the front end of the quick-freezing chamber 1 and is connected to the power motor for transmission. Several flexible cleaning strips 27 are provided at one end of the cleaning plate 26 near the vertical loop conveyor. A chip collection groove is provided below the cleaning mechanism. The chip collection groove can be detachably installed at the bottom of the quick-freezing chamber 1.

[0026] The cleaning plate 26 is driven to rotate by a motor. The flexible cleaning strip 27 at its end adheres to the surface of the open clamping plate 12 and dynamically sweeps away fish scales, debris, frost, and other impurities that adhere to the clamping plate 12 during the quick-freezing process. This effectively keeps the clamping plate 12 clean and prevents residual impurities from affecting subsequent clamping, quick-freezing, and unloading operations. All impurities and frost debris that fall off the brush fall into the debris collection trough, which can be disassembled and cleaned periodically by the staff.

[0027] In this embodiment, both the feed inlet 4 and the discharge outlet 5 extend outwards, and a leak-proof cold strip 28 is installed on the outside of the port, which respectively constitute the pre-cooling section of the feed conveying mechanism 2 and the cold preservation section of the discharge conveying mechanism 3.

[0028] In this embodiment, both the feeding conveyor 2 and the discharging conveyor 3 adopt a conveyor mesh belt structure, and several drying fans 29 are installed above the feeding conveyor 2; the driving component is a chain conveyor; both the feeding conveyor 2 and the discharging conveyor 3 adopt a hollow conveyor mesh belt structure, which is unobstructed and highly breathable, and can avoid product accumulation of water and frost, which is suitable for quick-freezing and drying operations; and the drying fans 29 can quickly dry the moisture attached to the surface of the fish before the fish products enter the quick-freezing chamber 1, realizing pre-drying treatment and reducing frost and ice formation during quick-freezing from the source.

[0029] The anti-leakage cold strip 28 can seal the gaps at the ports, greatly reducing the leakage of low-temperature cold air from the quick-freezing chamber 1. This not only reduces cold loss and saves energy, but also cools the incoming products in advance through the pre-cooling section and maintains the low temperature of the outgoing products through the cold preservation section, preventing the products from rapidly warming up after being discharged.

[0030] The working principle of this embodiment is as follows: After the quick-frozen product has undergone surface pre-drying by the feeding conveyor mechanism 2, it is conveyed to the feeding station bearing plate 22. The cyclically running clamping component 10 automatically picks up and clamps the product through mechanical linkage, achieving fully automatic feeding. Subsequently, the product moves in a closed loop with the vertical loop conveyor device. During the conveying process, it is combined with mechanical rotation and gravity free flipping, relying on the surrounding low-temperature cavity formed by the main quick-freezing mechanism 24 and the auxiliary quick-freezing mechanism 25 to complete all-round uniform quick-freezing. After quick-freezing, the clamping component 10 moves to the discharge station clamping plate 12, which automatically opens and actively and completely separates from the product contact surface to avoid freeze-stick adhesion. The product is automatically unloaded by its own weight and stably delivered by the discharge conveyor mechanism 3. The discharge cold preservation structure can effectively maintain the low-temperature quality of the product. After unloading, the clamping component 10 is cleaned by the cleaning plate 26 and the flexible cleaning strip 27 and continues to be conveyed to enter the next round of operation.

[0031] 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.
