Description

Technical Field

[0001] The invention belongs to the technical field of fish ball processing equipment and relates to freezing equipment for fish ball production. Background Art

[0002] During fish ball production, the freezing process significantly impacts product quality and production efficiency. Traditional fish ball freezing equipment often suffers from numerous problems: A low degree of automation requires manual operation for everything from loading and sorting fish balls to pallet transfer, resulting in low efficiency and the risk of damage due to improper operation. Inadequate sorting accuracy leads to fish balls easily stacking and sticking together, resulting in frequent collisions during feeding, impacting product integrity. The freezing effect is poor, with uneven cold air distribution, resulting in insufficient cooling of some fish balls. Furthermore, surface moisture cannot be drained smoothly during freezing, further reducing freezing efficiency. Furthermore, the various processes are loosely connected, and equipment coordination is poor, making it difficult to adapt to subsequent automated packaging processes, which in turn restricts the overall production process.

[0003] Therefore, we propose a freezing equipment for fish ball production, which can realize the fully automatic circulation, precise material distribution and efficient and uniform freezing of fish balls. The various processes are closely connected and can meet the quality and production capacity requirements of fish balls and similar meatball products for large-scale production. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a freezing equipment for fish ball production. The technical problem to be solved by the invention is: how to realize that the freezing equipment can complete the fully automatic circulation, precise material distribution and efficient and uniform freezing of fish balls, and the various processes are closely connected to meet the quality and production capacity requirements of fish balls and similar frozen meatball products in large-scale production.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A freezing device for fish ball production comprises a feeding mechanism, a feeding mechanism, a mobile conveyor belt machine, a preparatory conveyor belt machine, a transfer conveyor belt machine, a quick-freezing assembly, a tunnel freezer, a cold air generator and several tray assemblies, wherein the preparatory conveyor belt machine and the tunnel freezer are respectively located at two ends of the mobile conveyor belt machine, the transfer conveyor belt machine is located at an end of the tunnel freezer away from the mobile conveyor belt machine, the running direction of the preparatory conveyor belt machine is perpendicular to the running direction of the mobile conveyor belt machine, and a push plate assembly is provided on the end of the preparatory conveyor belt machine close to the mobile conveyor belt machine, the feeding mechanism is located on a side of the preparatory conveyor belt machine away from the mobile conveyor belt machine, the lower end of the feeding mechanism is located above the end of the mobile conveyor belt machine away from the tunnel freezer, the upper end of the feeding mechanism is located below the upper end of the feeding mechanism, the quick-freezing assembly is located above the mobile conveyor belt machine, and the quick-freezing assembly is located between the preparatory conveyor belt machine and the tunnel freezer, the quick-freezing assembly is connected to the cold air generator, and several tray assemblies are placed on the preparatory conveyor belt machine.

[0006] The working principle of the present invention is as follows: first, the tray assembly is placed on the preparation conveyor in sequence, the push tray assembly pushes the tray assembly onto the mobile conveyor, and at the same time, the loading mechanism transports the fish balls to the distributing mechanism, the distributing mechanism disperses the fish balls and distributes them to the tray assembly on the mobile conveyor, then the fish balls move with the tray assembly and the mobile conveyor, and during the movement, pass through the quick-freezing assembly, which uses the cold air generated by the cold air generator to perform preliminary quick freezing on the surface of the fish balls. After the surface quick freezing is completed, the fish balls continue to move with the mobile conveyor to the inside of the tunnel freezer for deep freezing of the inner layer, and then, the fish balls that have completed the deep freezing of the inner layer in the tunnel freezer are moved with the tray assembly to the transfer conveyor and transferred to the next process, the mobile conveyor can drive the tray assembly to move and stay in an accurate position, during the movement, auxiliary components such as mechanical blocks and baffles can be set on the mobile conveyor to help the tray assembly stay in an accurate position, and the distributing mechanism can control the number of fish balls falling on the tray assembly to adapt to the subsequent packaging process, and the whole process realizes the freezing processing of the fish balls through the coordinated operation of various parts.

[0007] The feeding mechanism includes a water bath and a crawler elevator. The crawler elevator is arranged at an angle. The lower end of the crawler elevator is located inside the water bath, and the upper end of the crawler elevator is located above the preparatory conveyor belt. A partition is fixed on the crawler of the crawler elevator. The cross-section of the partition is L-shaped, and a number of drainage holes evenly distributed in a rectangular array are opened on the partition.

[0008] With the above structure, the fish balls that have completed the previous process are dumped into the water bath, the crawler elevator is started, and its inclined crawler starts to run. The L-shaped partition fixed on the crawler moves with the crawler. Since a number of drainage holes evenly distributed in a rectangular array are opened on the partition, when the crawler elevator lifts the fish balls from the inside of the water bath to above the preparatory conveyor, the fish balls are supported by the partition, and excess water is drained out through the drainage holes, thereby realizing the lifting, loading and preliminary drainage of the fish balls.

[0009] The material distribution mechanism includes a receiving plate and a receiving frame for supporting the receiving plate. The receiving plate is tilted, the upper end of the receiving plate is located below the upper end of the crawler elevator, and the lower end of the receiving plate is located above the mobile conveyor. Four straight and evenly distributed material distribution guide plates are fixed on the bottom plate at the lower end of the receiving plate. Five material distribution channels are formed between the four material distribution guide plates and the two side walls of the receiving plate. Protective plates are fixed at the lower ends of the four material distribution guide plates. Five material dropout ports are opened on the bottom plate at the lower end of the receiving plate. The positions and specifications of the material dropout ports are consistent with the material distribution channels. Corresponding to the channels, five blanking barrels are fixed at the lower end of the receiving tray, and the position and specifications of the blanking barrels correspond to the blanking port, and one of the side walls of the four dividing guide plates and the receiving tray are provided with a mounting hole one, and a dividing assembly is provided inside the mounting hole one. The five dividing assemblies are respectively located on one side of the five dividing channels, and counting sensors are fixed on the four dividing guide plates and one of the side walls of the receiving tray. The positions of the five counting sensors correspond to the five dividing assemblies, and a number of staggered protrusions are fixed on the bottom plate at the upper end of the receiving tray.

[0010] With the above structure, the receiving tray is tilted, and its upper end is located below the crawler elevator. After the fish balls fall into the receiving tray from the crawler elevator, they slide downward under the action of gravity. Several staggered protrusions fixed on the bottom plate at the upper end of the receiving tray disperse the fish balls and change their movement trajectory. The fish balls continue to slide down to the lower end of the receiving tray. Four straight and evenly distributed distribution guide plates and the two side walls of the receiving tray form five distribution channels. The fish balls enter the five distribution channels respectively. The distribution components on one side of each distribution channel can be installed and adjusted through mounting hole 1. Every time the distribution component works, a fish ball passes through, and the counting sensor monitors the number of fish balls passing through each distribution channel in real time. The passed fish balls are guided from the corresponding blanking port through the blanking cylinder to the tray assembly on the mobile conveyor belt to realize quantitative distribution of fish balls. The protective plate prevents the fish balls from splashing out of the distribution channel during the falling process, thereby ensuring the accuracy and stability of the distribution.

[0011] The material distribution assembly includes a rotating shaft and a motor. The rotating shaft is rotatably arranged inside the first mounting hole, and the rotating shaft is perpendicular to the bottom plate of the receiving tray. The motor is fixed above the first mounting hole, and the output shaft of the motor is transmission-connected to the rotating shaft. Two L-shaped rotating parts are fixed on the rotating shaft. The rotating parts are parallel to the bottom plate of the receiving tray. The bending part of the rotating parts is fixed on the rotating shaft, and rotating wheels are rotatably provided at both ends of the rotating parts.

[0012] With the above structure, in the initial state, one end of the rotating part close to the blanking barrel is located in the distribution channel to block the fish balls from falling, and the other end is located in the mounting hole 1. When the fish balls need to be released, the motor drives the rotating shaft to rotate, driving the L-shaped rotating part to rotate synchronously. At this time, the end of the rotating part close to the blanking barrel rotates toward the mounting hole 1 to release the first fish ball; at the same time, the other end of the rotating part rotates out of the mounting hole 1 to block the subsequent fish balls from moving forward. After the first fish ball passes through, the motor drives the rotating part to reset, releasing the obstruction to the next fish ball, so that the fish ball queue moves forward in sequence, waiting for the next release. Through the periodic rotation of the rotating part, the fish balls can be released one by one. The setting of the rotating wheel can reduce friction with the fish balls and avoid damage to the fish balls.

[0013] The push plate assembly includes a mounting base, a cylinder, a push plate and a baffle. The mounting base is fixed on the frame of the preparatory conveyor belt machine. The cylinder is horizontally arranged on the mounting base and is located above the preparatory conveyor belt machine. The telescopic direction of the telescopic end of the cylinder is perpendicular to the running direction of the preparatory conveyor belt machine. The push plate is fixed on the telescopic end of the cylinder, and the push plate is parallel to the running direction of the preparatory conveyor belt machine. A baffle is fixed at one end of the push plate, and the baffle is perpendicular to the push plate.

[0014] With the above structure, the mounting base is fixed on the preparatory conveyor to provide support for the entire assembly. When the pallet assembly needs to be pushed from the preparatory conveyor to the mobile conveyor, the cylinder is started, and its telescopic end extends in a direction perpendicular to the running direction of the preparatory conveyor. Since the push plate is fixed on the telescopic end of the cylinder and is parallel to the running direction of the preparatory conveyor, the push plate moves synchronously with the telescopic end of the cylinder. The baffle fixed at one end of the push plate is parallel to the push plate. During the pushing process, the baffle serves to block subsequent pallet assemblies, ensuring that the pallet assemblies can be pushed to the mobile conveyor in sequence and stably by the push plate. After the pushing is completed, the telescopic end of the cylinder retracts, the push plate and the baffle are reset, and the subsequent pallet assembly moves forward, waiting for the next pushing operation.

[0015] The tray assembly includes a lower plate and an upper cover, the cross-sections of the lower plate and the upper cover are square, the upper end of the lower plate is located inside the lower end of the upper cover, four rectangular evenly distributed guide posts are fixed inside the upper cover, and four guide sleeves are fixed inside the lower plate, and the positions and specifications of the guide sleeves correspond to the guide posts, and the lower ends of the guide posts are slidably arranged inside the guide sleeves, and a spring is provided inside the guide sleeves, and the two ends of the spring respectively abut against the guide posts and the guide sleeves, and a number of mounting holes 2 evenly distributed in a rectangular array are provided on the upper end surface of the upper cover, and the number and positions of the mounting holes 2 correspond to the material distribution channels, and the interiors of the mounting holes 2 are provided with accommodating components, four ventilation pipes are fixed on the upper end of the upper cover, and the four ventilation pipes are connected to the lower ends of the several accommodating components through hoses and multi-way joints, and a number of water outlets are provided on the side walls of the lower plate, and a horizontally arranged wave bar 1 is fixed on the two opposite outer walls of the upper cover, and a wave bar 2 is fixed above the guide plates on both sides of the mobile conveyor, and the positions and specifications of the wave bar 1 and the wave bar 2 correspond.

[0016] With the above structure, the lower plate and the upper cover are connected by the guide column and the guide sleeve. The spring in the guide sleeve provides buffering and reset effects. At the same time, the upper cover can move up and down. When the tray assembly is located on the preparatory conveyor, the push plate assembly pushes it to move to the mobile conveyor. During the movement, the wave bar 1 contacts the wave bar 2 and produces relative movement, causing the upper cover to vibrate up and down relative to the lower plate to prevent the fish balls from sticking to the accommodating assembly. The tray assembly moves forward driven by the mobile conveyor, and the fish balls fall into the accommodating assembly in the second mounting hole corresponding to the accommodating channel through the blanking barrel of the distributing mechanism. The accommodating assembly It is divided into several rows, with five in each row. Each time the fish balls fall, they fall into the same row of containing components. Then, the tray component is moved forward by the moving conveyor belt for the distance of one row, and the next row of containing components is aligned with the blanking barrel. During the process, mechanical blocks, baffles and other auxiliary components can be set on the moving conveyor belt to help the tray component stay in the correct position. The vent pipe is connected to the containing component through a hose and a multi-way joint to ensure gas circulation during the quick-freezing process and improve the quick-freezing effect. The residual water on the fish balls can fall through the containing component and fall on the lower plate, and can be poured out through the water outlet on the side wall of the lower plate later.

[0017] The accommodating component includes a accommodating hemisphere 1, a spherical shell, a drain pipe and an air inlet pipe. The accommodating hemisphere 1 is fixed inside the mounting hole 2, the spherical shell is located outside the accommodating hemisphere 1, and the spherical shell forms a sandwich between the accommodating hemisphere 1, the upper end of the spherical shell is fixed on the upper cover, the drain pipe is vertically fixed to the lower end of the spherical shell, and the drain pipe is connected to the interior of the spherical shell, the air inlet pipe is horizontally arranged on the drain pipe, and the air outlet end of the air inlet pipe is connected to the middle position of the drain pipe, the air inlet end of the air inlet pipe is connected to the vent pipe through a hose and a multi-way joint, and the accommodating hemisphere A plurality of air inlet holes 1 are uniformly distributed in a circumferential array on the side wall of the first, and the air inlet holes 1 are all arranged along the circumferential inclination direction of the accommodating hemisphere 1. An air inlet hole 2 is provided at the lower end of the accommodating hemisphere 1, and the axis of the air inlet hole 2 is located in a vertical plane, and the air inlet hole 2 is arranged along the circumferential inclination direction of the accommodating hemisphere 1. A horizontally arranged moving cylinder is slidingly provided inside the air inlet pipe, and the end of the moving cylinder away from the air inlet end of the air inlet pipe is closed, and an air outlet is provided at the upper end of the moving cylinder, and a fixing ring is fixed inside the air inlet end of the air inlet pipe, and a tension spring is provided between the fixing ring and the moving cylinder.

[0018] With the above structure, the fish balls fall from the dropper of the material distribution mechanism into the accommodating hemisphere 1 fixed inside the second mounting hole, and the spherical shell outside the accommodating hemisphere 1 forms a sandwich with it. The excess water on the surface of the fish balls can flow through the gap between the accommodating hemisphere 1 and the spherical shell to the drain pipe at the lower end of the spherical shell and be discharged into the lower plate. After reaching the corresponding position of the quick-freezing component, the ventilation pipe transports the cold air through the intake pipe through the hose and the multi-way joint. The moving cylinder in the intake pipe slides under the action of the gas pressure to overcome the tension of the tension spring, and its upper end The air outlet is connected with the upper end of the drain pipe, so that the gas enters the drain pipe, and then enters the interior of the accommodating hemisphere one through the air inlet holes 1 that are evenly distributed in a circumferential array on one side wall of the accommodating hemisphere and inclined along the circumferential direction, and the air inlet holes 2 whose lower end axis is located in a vertical plane and inclined along the circumferential direction, blowing up the fish balls and rotating the fish balls, thereby evenly freezing the surface of the fish balls and quickly freezing the surface of the fish balls. When the gas pressure decreases, the tension spring pulls the moving cylinder to reset, thereby realizing dynamic adjustment of gas delivery, ensuring the quick-freezing effect and drainage efficiency of the fish ball surface.

[0019] The quick-freezing assembly includes a support frame, the support frame is arranged on the side of the frame of the mobile conveyor machine, the upper end of the support frame is fixed with a mounting plate, the upper end of the mounting plate is fixed with an electric push rod, the telescopic end of the electric push rod passes downward through the mounting plate, and the telescopic end of the electric push rod is fixed with a movable pressure plate, the upper end of the movable pressure plate is fixed with two symmetrical guide rods, the guide rods are slidably arranged on the mounting plate, the specifications of the movable pressure plate are adapted to the upper cover, and a plurality of accommodating hemisphere twos are fixed at the lower end of the movable pressure plate, the number, position and specifications of the plurality of accommodating hemisphere twos correspond to the accommodating hemisphere one, four air injection nozzles are fixed at the lower end of the movable pressure plate, the position and specifications of the air injection nozzles correspond to the ventilation pipe, the air injection nozzles are provided with a sealing ring, the upper end of the movable pressure plate is fixed with a connecting pipe, the lower end of the connecting pipe is connected with the four air injection nozzles through a hose and a multi-way joint, and the upper end of the connecting pipe is connected with the cold air generator through a hose and an electric control valve.

[0020] With the above structure, the support frame provides support for the entire assembly. When the tray assembly carrying the fish balls moves to the bottom of the quick-freezing assembly with the mobile conveyor and stops, the electric push rod is started, and its telescopic end pushes the movable pressure plate downward. The two symmetrical guide rods slide along the mounting plate to provide guidance for the movement of the movable pressure plate to ensure its smooth downward movement. The several accommodating hemispheres 2 at the lower end of the movable pressure plate correspond to the accommodating hemisphere 1 on the upper cover of the tray assembly to form a limit for the fish balls. At the same time, the four air injection nozzles correspond to the ventilation pipes of the upper cover. The sealing rings on the air injection nozzles ensure the sealing effect. The connecting pipe transports the cold air generated by the cold air generator to the air injection nozzles through the hose and the multi-way connector, and then introduces it into the accommodating assembly through the ventilation pipe to achieve rapid freezing of the surface of the fish balls. After the surface quick freezing is completed, the electric push rod drives the movable pressure plate to reset, waiting for the next tray assembly to enter the working area.

[0021] Compared with the existing technology, this fish ball production freezing equipment has the following advantages: 1. Through the coordination of the loading mechanism, the dividing mechanism, the mobile conveyor belt, the preparatory conveyor belt, the transfer conveyor belt and the push tray assembly, the tray assembly is used to drive the fish balls to automatically complete the various processes of loading and draining, precise dividing, mobile transportation, initial quick freezing, deep freezing and subsequent transfer. Each link does not require excessive manual intervention, greatly improving production efficiency.

[0022] 2. The fish balls are dispersed and dropped by cooperating with the distribution mechanism and the tray assembly, which prevents the fish balls from sticking to each other and the fish balls from sticking to the tray assembly, reduces the collision damage of the fish balls during movement, and ensures the accuracy of distribution.

[0023] 3. Through the cooperation of the quick-freezing component, tunnel freezer and tray component, the quick-freezing component evenly applies cold air to the fish balls through the tray component, and can drive the fish balls to rotate to avoid uneven cooling of the fish balls. Combined with the deep freezing of the tunnel freezer, the freezing efficiency and effect are greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Since a number of drainage holes 12 evenly distributed in a rectangular array are provided on the partition, when the crawler elevator 11 lifts the fish balls from the inside of the water bath 10 to the top of the preparatory conveyor 4, the fish balls are held up by the partition, and excess water is drained out through the drainage holes 12, thereby realizing the lifting, loading and preliminary drainage of the fish balls.

[0044] The material distribution mechanism 2 includes a receiving plate 13 and a receiving frame for supporting the receiving plate 13. The receiving plate 13 is tilted, and the upper end of the receiving plate 13 is located below the upper end of the crawler elevator 11, and the lower end of the receiving plate 13 is located above the mobile conveyor 3. Four straight and evenly distributed material distribution guide plates 14 are fixed on the bottom plate at the lower end of the receiving plate 13.

Since the push plate 27 is fixed on the telescopic end of the cylinder 26 and is parallel to the running direction of the preparatory conveyor 4, the push plate 27 moves synchronously with the telescopic end of the cylinder 26. The baffle 28 fixed at one end of the push plate 27 is parallel to the push plate 27. During the pushing process, the baffle 28 serves to block the subsequent pallet assembly 9, ensuring that the pallet assembly 9 can be pushed to the mobile conveyor 3 in sequence and stably by the push plate 27. After the pushing is completed, the telescopic end of the cylinder 26 retracts, the push plate 27 and the baffle 28 are reset, and the subsequent pallet assembly 9 moves forward, waiting for the next pushing operation.

[0050] The tray assembly 9 includes a lower plate 29 and an upper cover 30. The cross-sections of the lower plate 29 and the upper cover 30 are both square. The upper end of the lower plate 29 is located inside the lower end of the upper cover 30. Four rectangular evenly distributed guide posts 31 are fixed inside the upper cover 30. Four guide sleeves 32 are fixed inside the lower plate 29. The positions and specifications of the guide sleeves 32 correspond to the guide posts 31. The lower end of the guide post 31 is slidably set inside the guide sleeve 32. A spring 33 is provided inside the guide sleeve 32. The two ends of the spring 33 respectively contact the guide post 31 and the guide sleeve 32. The upper end surface of the upper cover 30 is provided with a plurality of rectangular arrays evenly distributed mounting holes. Hole 2 37, the number and position of mounting hole 2 37 correspond to the material distribution channel, and the interior of mounting hole 2 37 is provided with a accommodating component 34. Four ventilation pipes 35 are fixed to the upper end of the upper cover 30, and the four ventilation pipes 35 are connected to the lower ends of several accommodating components 34 through hoses and multi-way connectors. Several water outlet holes 36 are opened on the side wall of the lower plate 29. Horizontally arranged wave strips 1 38 are fixed on the two opposite outer walls of the upper cover 30, and wave strips 2 39 are fixed above the guide plates on both sides of the mobile conveyor 3. The positions and specifications of wave strips 1 38 and wave strips 2 39 correspond.

[0051] In this embodiment, the lower plate 29 and the upper cover 30 are connected by the guide column 31 and the guide sleeve 32. The spring 33 in the guide sleeve 32 provides a buffering and reset function. At the same time, the upper cover 30 can move up and down. When the tray assembly 9 is located on the preparatory conveyor 4, the push plate assembly 6 pushes it to move to the mobile conveyor 3. During the movement, the wave bar 1 38 contacts the wave bar 2 39 and produces relative movement, causing the upper cover 30 to vibrate up and down relative to the lower plate 29 to prevent the fish balls from sticking to the accommodating assembly 34. The tray assembly 9 moves forward driven by the mobile conveyor 3, and the fish balls fall into the accommodating assembly 3 in the mounting hole 2 37 corresponding to the distributing channel through the blanking barrel 16 of the distributing mechanism 2. 4, the containing components 34 are divided into several rows, with five in each row. Each time the fish balls fall, they fall into the same row of containing components 34. Then, the tray component 9 moves forward a row distance under the drive of the mobile conveyor 3, and aligns the next row of containing components 34 with the blanking barrel 16. During the process, auxiliary components such as mechanical blocks and baffles can be set on the mobile conveyor 3 to help the tray component 9 stay in the correct position. The vent pipe 35 is connected to the containing component 34 through a hose and a multi-way joint to ensure gas circulation during the quick freezing process and improve the quick freezing effect. The residual water on the fish balls can fall through the containing component 34 and fall on the lower plate 29, and can be poured out through the water outlet 36 on the side wall of the lower plate 29.

[0052] The accommodating component 34 includes a accommodating hemisphere 1 40, a spherical shell 41, a drain pipe 42 and an air inlet pipe 43. The accommodating hemisphere 1 40 is fixed inside the mounting hole 2 37. The spherical shell 41 is located on the outside of the accommodating hemisphere 1 40, and the spherical shell 41 forms a sandwich between the accommodating hemisphere 1 40. The upper end of the spherical shell 41 is fixed on the upper cover 30. The drain pipe 42 is vertically fixed to the lower end of the spherical shell 41, and the drain pipe 42 is connected to the interior of the spherical shell 41. The air inlet pipe 43 is horizontally arranged on the drain pipe 42, and the air outlet end of the air inlet pipe 43 is connected to the middle position of the drain pipe 42. The air inlet end of the air inlet pipe 43 is connected to the vent pipe 35 through a hose and a multi-way joint. A plurality of air inlet holes 44 are provided on the side wall of hemisphere 140 in a circumferential array. The air inlet holes 44 are all arranged along the circumferential tilt direction of the hemisphere 140. An air inlet hole 2 45 is provided at the lower end of the hemisphere 140. The axis of the air inlet hole 2 45 is located in a vertical plane, and the air inlet hole 2 45 is arranged along the circumferential tilt direction of the hemisphere 140. A horizontally arranged moving cylinder 46 is provided for sliding inside the air inlet pipe 43. The end of the moving cylinder 46 away from the air inlet end of the air inlet pipe 43 is closed, and an air outlet hole 47 is provided at the upper end of the moving cylinder 46. A fixing ring 48 is fixed inside the air inlet end of the air inlet pipe 43, and a tension spring 49 is provided between the fixing ring 48 and the moving cylinder 46.

[0053] In this embodiment, the fish balls fall from the drop barrel 16 of the distributing mechanism 2 into the accommodating hemisphere 1 40 fixed inside the second mounting hole 37, and the spherical shell 41 outside the accommodating hemisphere 1 40 forms a sandwich with it. The excess moisture on the surface of the fish balls can flow through the gap between the accommodating hemisphere 1 40 and the spherical shell 41 to the drain pipe 42 at the lower end of the spherical shell 41 and be discharged into the lower plate 29. After reaching the corresponding position of the quick-freezing component 7, the vent pipe 35 transports the cold air through the intake pipe 43 through the hose and the multi-way joint. The movable cylinder 46 in the intake pipe 43 overcomes the tension of the tension spring 49 under the action of the gas pressure. The force slides, and the air outlet 47 at its upper end is connected with the upper end of the drain pipe 42, so that the gas enters the drain pipe 42, and then enters the interior of the accommodating hemisphere 40 through the air inlet holes 44 evenly distributed in a circumferential array on the side wall of the accommodating hemisphere 40 and inclined along the circumferential direction, and the air inlet hole 2 45 whose lower end axis is located in a vertical plane and inclined along the circumferential direction, blowing up the fish balls and rotating the fish balls, uniformly freezing the surface of the fish balls, and quickly freezing the surface of the fish balls. When the gas pressure decreases, the tension spring 49 pulls the moving cylinder 46 to reset, realizing dynamic adjustment of gas delivery, ensuring the quick-freezing effect and drainage efficiency of the fish balls.

[0054] The quick freezing assembly 7 includes a support frame 50, which is arranged on the side of the frame of the mobile conveyor 3. A mounting plate 51 is fixed to the upper end of the support frame 50, and an electric push rod 52 is fixed to the upper end of the mounting plate 51. The telescopic end of the electric push rod 52 passes downward through the mounting plate 51, and a movable pressure plate 54 is fixed to the telescopic end of the electric push rod 52. Two symmetrical guide rods 53 are fixed to the upper end of the movable pressure plate 54. The guide rods 53 are slidably arranged on the mounting plate 51. The specifications of the movable pressure plate 54 are adapted to the upper cover 30. The lower end of the movable pressure plate 54 is fixed to the upper end of the movable pressure plate 54. Several accommodating hemispheres 2 55 are fixed thereto, and the number, position and specifications of the accommodating hemispheres 2 55 correspond to those of the accommodating hemisphere 1 40. Four gas injection nozzles 56 are fixed to the lower end of the movable pressure plate 54, and the positions and specifications of the gas injection nozzles 56 correspond to those of the ventilation pipe 35. A sealing ring 57 is provided on the gas injection nozzle 56. A connecting pipe 58 is fixed to the upper end of the movable pressure plate 54, and the lower end of the connecting pipe 58 is connected to the four gas injection nozzles 56 through a hose and a multi-way connector, and the upper end of the connecting pipe 58 is connected to the cold air generator through a hose and an electric control valve.

[0055] The fish balls are then moved to the bottom of the quick-freezing assembly 7 by the support frame 50. In this embodiment, the support frame 50 provides support for the entire assembly. When the tray assembly 9 carrying the fish balls moves to the bottom of the quick-freezing assembly 7 with the mobile conveyor 3 and stops, the electric push rod 52 is started, and its telescopic end pushes the movable pressing plate 54 downward. The two symmetrical guide rods 53 slide along the mounting plate 51 to provide guidance for the movement of the movable pressing plate 54 to ensure its smooth downward movement. The several accommodating hemispheres 2 55 at the lower end of the movable pressing plate 54 correspond to the accommodating hemisphere 1 40 of the upper cover 30 of the tray assembly 9, forming a limit for the fish balls. At the same time, the four air injection nozzles 56 correspond to the vent pipe 35 of the upper cover 30, and the sealing ring 57 on the air injection nozzle 56 ensures the sealing effect. The connecting pipe 58 transports the cold air generated by the cold air generator to the air injection nozzle 56 through the hose and the multi-way connector, and then introduces it into the accommodating assembly 34 through the vent pipe 35 to achieve rapid freezing of the surface of the fish balls. After the surface quick freezing is completed, the electric push rod 52 drives the movable pressing plate 54 to reset, waiting for the next tray assembly 9 to enter the working area.

[0056] The working principle of the present invention is as follows: first, the tray assemblies 9 are placed on the preparatory conveyor 4 in sequence, and the cylinder 26 of the push plate assembly 6 drives the push plate 27 and the baffle 28 to push the tray assemblies 9 to the mobile conveyor 3. During the pushing process, the baffle 28 blocks the subsequent tray assemblies 9 to ensure sequential pushing; At the same time, the fish balls that have completed the previous process are placed in the water bath box 10, and the crawler elevator 11 lifts the fish balls and drains them through the L-shaped partition with drainage holes 12, and then transports them to the receiving tray 13 of the distributing mechanism 2. After the fish balls are dispersed on the receiving tray 13 by the protrusion 20, they slide down along the five distributing channels, and the motor 24 of the distributing assembly 17 drives the rotating shaft 21 and the rotating member 22 to rotate periodically, and cooperates with the counting sensor 19 to realize the quantitative release of the fish balls one by one, and falls into the receiving assembly 34 of the tray assembly 9 on the mobile conveyor 3 through the blanking cylinder 16. When the tray assembly 9 moves on the mobile conveyor 3, the wave bar 1 38 and the wave bar 2 39 cooperate to make the upper cover 30 vibrate relative to the lower plate 29 to prevent the fish balls from sticking. At the same time, the buffer reset is achieved by the guide column 31, the guide sleeve 32 and the spring 33, and the excess water on the fish balls flows to the lower plate 29 through the drainage pipe 42. In the subsequent process, it can be discharged through the water outlet 36 on the side wall of the lower plate 29; Next, the tray assembly 9 carrying the fish balls passes through the quick-freezing assembly 7 along the mobile conveyor 3. The electric push rod 52 drives the movable pressing plate 54 to move downward, and the second accommodating hemisphere 55 and the first accommodating hemisphere 40 fit together to limit the fish balls. The air injection nozzle 56 connects to the ventilation pipe 35 and is sealed by the sealing ring 57. The cold air from the cold air generator is introduced into the accommodating assembly 34 through the connecting pipe 58, the air injection nozzle 56, and the ventilation pipe 35. The cold air passes through the air inlet pipe 43, the movable cylinder 46, and the drain pipe 42, and enters the accommodating hemisphere 1 40 from the air inlet hole 1 44 and the air inlet hole 2 45, causing the fish balls to rotate and undergoing rapid surface freezing to prevent mutual adhesion and enhance the strength of the fish balls. After the initial quick freezing, the fish balls continue to move with the tray assembly 9 to the tunnel freezer 8 for deep freezing of the inner layer. After completion, they are moved with the tray assembly 9 to the transfer conveyor 5 for transmission to the next process. During the whole process, the mobile conveyor 3 can ensure the accurate positioning of the tray assembly 9 through auxiliary components such as mechanical blocks, and the various parts work together to realize the freezing processing of the fish balls.

[0057] In summary, the feeding mechanism 1, the dividing mechanism 2, the mobile conveyor 3, the preparatory conveyor 4, the transfer conveyor 5 and the push plate assembly 6 cooperate with the tray assembly 9 to drive the fish balls to automatically complete the various processes of feeding and draining, precise dividing, mobile transportation, initial quick freezing, deep freezing and subsequent transfer. Each link does not require excessive manual intervention, thereby greatly improving production efficiency. The fish balls are dispersed and dropped by cooperating with the distributing mechanism 2 and the tray assembly 9, thereby preventing the fish balls from sticking to each other and to the tray assembly 9, reducing the collision damage of the fish balls during movement, and ensuring the accuracy of the distribution. By cooperating with the quick-freezing component 7, the tunnel freezer 8 and the tray component 9, the quick-freezing component 7 applies cold air evenly to the fish balls through the tray component 9, and can drive the fish balls to rotate to avoid uneven cooling of the fish balls. Combined with the deep freezing of the tunnel freezer 8, the freezing efficiency and effect are greatly improved.
