Description

Technical Field

[0001] This invention relates to the field of food quick-freezing technology, and in particular to a gradient cooling quick-freezing device for frozen whole chicken wings and its method of use. Background Technology

[0002] Frozen chicken wings refer to poultry products where the wing parts of a whole chicken are frozen after processing. They are typically produced using flash-freezing technology, which rapidly cools the chicken wings to extremely low temperatures to maintain their freshness, texture, nutritional content, and appearance, facilitating long-term storage and transportation.

[0003] Current gradient cooling quick-freezing devices for frozen whole chicken wings can freeze whole chicken wings, but they do not allow for turning the chicken wings over during freezing, or the chicken wings may stick to the placement plate due to freezing and cannot be turned over. This results in uneven freezing of the chicken wings and reduces the freezing effect. Therefore, there is an urgent need to design a gradient cooling quick-freezing device for frozen whole chicken wings. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a gradient cooling quick-freezing device for frozen whole chicken wings and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gradient cooling quick-freezing device for frozen whole chicken wings, including a plate conveyor belt, and also including:

[0007] The refrigeration chamber is installed on top of the plate conveyor belt. The refrigeration chamber is equipped with multiple refrigeration chambers and is used for segmented refrigeration of whole chicken wings.

[0008] The racks are multiple and are evenly fixedly installed on the inside of the plate conveyor belt, with the racks and the cooling chambers corresponding to each other.

[0009] The conveyor turning assembly consists of multiple conveyor turning assemblies, which are evenly arranged on the surface of the plate conveyor belt. The conveyor turning assemblies are used to convey whole chicken wings into the refrigeration chamber and turn them over.

[0010] The conveying and flipping assembly includes:

[0011] A triangular box is positioned above the horizontal edge of the plate conveyor belt and is used to hold whole chicken wings.

[0012] The flipping mechanism is mounted on the plate conveyor belt and is used to reciprocate flipping the triangular box.

[0013] An auxiliary mechanism is installed on the plate conveyor belt and is used to assist in the separation of whole chicken wings and triangular boxes.

[0014] As a further technical solution of the present invention, the auxiliary mechanism includes: a first limiting plate, which is vertically fixedly installed on the top of the plate conveyor belt; a rotating shaft is horizontally fixedly installed on the side of the first limiting plate, and the end of the rotating shaft is rotatably installed on one end of the triangular box; a first friction disc is fixedly sleeved on the rotating shaft and a second friction disc is rotatably sleeved on the rotating shaft; the second friction disc is fixed on the end face of the triangular box; and the opposing surfaces of the first friction disc and the second friction disc are in contact.

[0015] As a further technical solution of the present invention, strip grooves are provided on both sides of the triangular box, and round bars are rotatably installed inside the two strip grooves. The rotation of the round bars is used to assist in the separation of the whole chicken wing and the triangular box.

[0016] As a further technical solution of the present invention, two first gears are rotatably mounted on the end face of the triangular box. The end faces of the two first gears are respectively mounted at the center of the end faces of the two round bars through a connecting shaft. The surfaces of the two first gears are fitted with meshing toothed rings, and the toothed rings are fixedly mounted on the side of the first limiting plate.

[0017] As a further technical solution of the present invention, the flipping mechanism includes: a second limiting plate, which is vertically fixedly installed on the surface of the plate conveyor belt, and a rotating rod is horizontally rotatably installed on the outer side of the second limiting plate. A sleeve plate is rotatably sleeved on the surface of the rotating rod. The sleeve plate is L-shaped and its horizontal edge is fixedly installed on the outer side of the second limiting plate.

[0018] As a further technical solution of the present invention, a one-way bearing is fixedly sleeved on the end of the rotating rod surface, a second gear is fixedly sleeved on the outer ring of the one-way bearing, a rack is used to rotate the second gear, a torsion spring is sleeved on the rotating rod surface, and the two ends of the torsion spring are respectively fixedly installed on the side of the sleeve plate and the side of the second gear.

[0019] As a further technical solution of the present invention, a grooved plate is also provided on the outer side of the second limiting plate. A missing gear is fixed at the center of the inner end face of the groove of the grooved plate, and a first shaft rod rotatably mounted on the side of the second limiting plate is fixed at the center of the end face of the missing gear. An arc-shaped rack is fixed on the inner wall of the groove of the grooved plate.

[0020] As a further technical solution of the present invention, a second shaft is horizontally rotatably mounted on the outer side of the second limiting plate. The end face of the second shaft is fixedly mounted on the end face of the triangular box through a connecting shaft. A third gear is fixed at the other end of the second shaft. The third gear is located between the missing gear and the arc-shaped rack. The missing gear and the arc-shaped rack are used to make the third gear rotate in both directions.

[0021] As a further technical solution of the present invention, a small pulley is fixed at the center of the outer end face of the groove plate, a large pulley is fixedly sleeved on the surface of the rotating rod, and belts are sleeved on the surfaces of the small pulley and the large pulley.

[0022] As a further technical solution of the present invention, a helical gear is fixedly sleeved on the surface of the rotating rod, and a V-shaped plate is rotatably installed on the outer side of the second limiting plate. A first arc-shaped block and a second arc-shaped block are fixed at both ends of the V-shaped plate, and a counterweight ball is fixedly installed on the side of the V-shaped plate. The V-shaped plate, together with the first arc-shaped block and the second arc-shaped block, is used to escape the helical gear.

[0023] The method for using a gradient cooling quick-freezing device for frozen whole chicken wings includes the following steps:

[0024] S1: When freezing whole chicken wings, first place the chicken wings in a triangular box, then transport the triangular box containing the chicken wings to the corresponding refrigeration chamber of the refrigeration unit via a plate conveyor belt for segmented gradient cooling and quick freezing. Both the refrigeration unit and the refrigeration chamber are mature existing technologies, and the refrigeration temperature of the refrigeration chamber decreases sequentially. When the plate conveyor belt moves the triangular box and its connecting parts together, the second gear meshes with the rack and pinion, causing the second gear to rotate. At this time, the rotation of the second gear does not drive the rotating rod to rotate through the one-way bearing, but the rotation of the second gear will generate torque in the torsion spring. When the corresponding rack and second gear finish meshing, the torque of the torsion spring will be released, causing the second gear to rotate clockwise. The rotation will drive the rotating rod to rotate clockwise via a one-way bearing. The rotation of the rotating rod will drive the helical gear and the large pulley to rotate. The clockwise rotation of the helical gear will first move the first arc block away from the helical gear. The movement of the first arc block will drive the V-shaped plate to rotate. The rotation of the V-shaped plate will drive the second arc block to move towards the helical gear. The second arc block will be located between the adjacent helical teeth of the helical gear. Due to the shear inertia of the counterweight, it will hinder the rotation of the helical gear. However, the continuous release of the torsion spring will cause the helical gear to rotate, which will again cause the second arc block to move away from the helical gear. At this time, the first arc block will move closer to the helical gear. In summary, this process repeats, realizing the escape of the helical gear, reducing the rotational speed of the helical gear and the rotating rod, and further reducing the release speed of the torsion spring torque.

[0025] S2: The large pulley rotates, accelerating the small pulley via a belt. The small pulley rotates, driving the grooved disc. The grooved disc rotates, driving the missing gear and the arc-shaped rack. When the missing gear meshes with the third gear, it drives the third gear to rotate 80 degrees forward. When the arc-shaped rack meshes with the third gear, it drives the third gear to rotate 80 degrees in the opposite direction, thus achieving reciprocating rotation of the third gear. The reciprocating rotation of the third gear drives the second shaft to rotate, which in turn drives the triangular box to rotate. This allows for the reciprocating flipping of the chicken wings placed inside the triangular box, ensuring even cooling. The rotation of the triangular box drives the circular bars and the first gear to revolve. Due to the gear ring, the two first gears also rotate on their own axis while revolving. The rotation of the two gears drives the rotation of the two circular bars, which can break off any frozen residue adhering to the inner wall of the triangular box, ensuring smooth flipping of the chicken wings.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention, through the arrangement of a triangular box, a flipping mechanism, and an auxiliary mechanism, enables the chicken wings to be flipped repeatedly in each refrigeration chamber during quick-freezing. In addition, round bars can be used to assist in flipping the chicken wings during the flipping process, preventing the chicken wings from sticking to the inner wall of the triangular box due to freezing and thus avoiding uneven cooling. This improves the effectiveness of the equipment. Attached Figure Description

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] 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.

[0041] Please see the appendix Figure 1 -Appendix Figure 10 A gradient cooling quick-freezing device for frozen whole chicken wings includes a plate conveyor belt 1, a refrigeration chamber 2, racks 28, and a conveying and turning assembly. The refrigeration chamber 2 is installed on top of the plate conveyor belt 1 and has multiple refrigeration compartments inside. The refrigeration chamber 2 is used for segmented refrigeration of whole chicken wings. There are multiple racks 28, which are evenly fixedly installed on the inner side of the plate conveyor belt 1 and are correspondingly arranged with the refrigeration compartments. There are multiple conveying and turning assemblies, which are evenly arranged on the surface of the plate conveyor belt 1 and are used to convey whole chicken wings into the refrigeration chamber 2 and turn them over. The conveying and turning assembly includes a triangular box 3, a turning mechanism, and an auxiliary mechanism. The triangular box 3 is located above the horizontal edge of the plate conveyor belt 1 and is used to hold whole chicken wings. The turning mechanism is located on the plate conveyor belt 1 and is used to reciprocate turning the triangular box 3. The auxiliary mechanism is located on the plate conveyor belt 1 and is used to assist in separating the whole chicken wings from the triangular box 3.

[0042] When quick-freezing whole chicken wings, the whole chicken wings can be turned over repeatedly in each refrigeration chamber. In addition, the round strip 8 can be used to assist in turning the whole chicken wings during the turning process, so as to avoid the whole chicken wings sticking to the inner wall of the triangular box 3 due to freezing and being unable to be turned over, which would cause uneven cooling.

[0043] Please see the appendix Figure 1-Appendix Figure 10 In a preferred embodiment, the flipping mechanism includes: a second limiting plate 9, which is vertically fixedly installed on the surface of the plate conveyor belt 1; a rotating rod 10 is horizontally rotatably installed on the outer side of the second limiting plate 9; a sleeve plate 11 is rotatably sleeved on the surface of the rotating rod 10; the sleeve plate 11 is L-shaped, and its horizontal edge is fixedly installed on the outer side of the second limiting plate 9; a one-way bearing 13 is fixedly sleeved on the end of the rotating rod 10; a second gear 12 is fixedly sleeved on the outer ring of the one-way bearing 13; a rack 28 is used to rotate the second gear 12; a torsion spring 14 is sleeved on the surface of the rotating rod 10, and both ends of the torsion spring 14 are respectively fixedly installed on the side of the sleeve plate 11 and the side of the second gear 12; a grooved plate 18 is also provided on the outer side of the second limiting plate 9; a missing gear 19 is fixedly fixed at the center of the inner end face of the groove of the grooved plate 18; a first shaft 21 is rotatably installed on the side of the second limiting plate 9 at the center of the end face of the missing gear 19; and the inner wall of the groove of the grooved plate 18 is fixed. There is an arc-shaped rack 20, and a second shaft 22 is horizontally rotatably mounted on the outer side of the second limiting plate 9. The end face of the second shaft 22 is fixedly mounted on the end face of the triangular box 3 through a connecting shaft. A third gear 23 is fixed at the other end of the second shaft 22. The third gear 23 is located between the missing gear 19 and the arc-shaped rack 20. The missing gear 19 and the arc-shaped rack 20 are used to make the third gear 23 rotate in both directions. A small pulley 17 is fixed at the center of the outer end face of the slotted plate 18. A large pulley 16 is fixedly sleeved on the surface of the rotating rod 10, and a belt 15 is sleeved on the surface of the small pulley 17 and the large pulley 16. A helical gear 24 is fixedly sleeved on the surface of the rotating rod 10, and a V-shaped plate 25 is rotatably mounted on the outer side of the second limiting plate 9. A first arc-shaped block 26 and a second arc-shaped block 27 are fixed at both ends of the V-shaped plate 25, and a counterweight ball 29 is fixedly mounted on the side of the V-shaped plate 25. The V-shaped plate 25, together with the first arc-shaped block 26 and the second arc-shaped block 27, is used to escape the helical gear 24.

[0044] When it is necessary to freeze whole chicken wings, first place the whole chicken wings in the triangular box 3, and then transport the triangular box 3 containing the whole chicken wings to the corresponding refrigeration chamber of the refrigeration chamber 2 through the plate conveyor belt 1 for segmented gradient cooling and quick freezing. It should be noted that both the refrigeration chamber 2 and the refrigeration chamber are mature existing technologies, and the refrigeration temperature of the refrigeration chamber decreases sequentially.

[0045] When the plate conveyor belt 1 moves together with the triangular box 3 and its connecting parts, the second gear 12 will mesh with the rack 28 and drive the second gear 12 to rotate. At this time, the rotation of the second gear 12 will not drive the rotating rod 10 to rotate through the one-way bearing 13, but the rotation of the second gear 12 will cause the torsion spring 14 to generate torque. When the corresponding rack 28 and the second gear 12 finish meshing, the torque of the torsion spring 14 will be released.

[0046] When the torque of the torsion spring 14 is released, the second gear 12 will rotate clockwise. The clockwise rotation of the second gear 12 will drive the rotating rod 10 to rotate clockwise through the one-way bearing 13. The rotation of the rotating rod 10 will drive the helical gear 24 and the large pulley 16 to rotate.

[0047] When the helical gear 24 rotates clockwise, the first arc block 26 moves away from the helical gear 24. The movement of the first arc block 26 drives the V-shaped plate 25 to rotate. The rotation of the V-shaped plate 25 drives the second arc block 27 to move towards the helical gear 24. The second arc block 27 will be located between the adjacent helical teeth of the helical gear 24. Due to the shear inertia of the counterweight, it will hinder the rotation of the helical gear 24. However, the continuous release of the torque of the torsion spring 14 will cause the helical gear 24 to rotate, which will cause the second arc block 27 to move away from the helical gear 24. At this time, the first arc block 26 moves closer to the helical gear 24. In summary, this process repeats, realizing the escape of the helical gear 24, reducing the rotational speed of the helical gear 24 and the rotating rod 10, and further reducing the release speed of the torque of the torsion spring 14.

[0048] The rotation of the large pulley 16 accelerates the rotation of the small pulley 17 via the belt 15. The rotation of the small pulley 17 drives the grooved disc 18 to rotate. The rotation of the grooved disc 18 drives the missing gear 19 and the arc rack 20 to rotate. When the missing gear 19 meshes with the third gear 23, it drives the third gear 23 to rotate 80 degrees in the forward direction. When the arc rack 20 meshes with the third gear 23, it drives the third gear 23 to rotate 80 degrees in the reverse direction, thus achieving the reciprocating rotation of the third gear 23.

[0049] Please see the appendix Figure 2 -Appendix Figure 10 In a preferred embodiment, the auxiliary mechanism includes: a first limiting plate 4, which is vertically fixedly installed on the top of the plate conveyor belt 1; a rotating shaft 5 is horizontally fixedly installed on the side of the first limiting plate 4; the end of the rotating shaft 5 is rotatably installed on one end of the triangular box 3; a first friction disc is fixedly sleeved on the rotating shaft 5 and a second friction disc is rotatably sleeved on the rotating shaft 5; the second friction disc is fixed to the end face of the triangular box 3; the first friction disc and the second friction disc are in contact with each other; both sides of the triangular box 3 are provided with strip-shaped column grooves; round bars 8 are rotatably installed inside the two strip-shaped column grooves; the round bars 8 are rotated to assist in the separation of the whole chicken wing from the triangular box 3; two first gears 7 are rotatably installed on the end face of the triangular box 3; the end faces of the two first gears 7 are respectively installed at the center of the end faces of the two round bars 8 through connecting shafts; meshing toothed rings 6 are sleeved on the surfaces of the two first gears 7; and the toothed rings 6 are fixedly installed on the side of the first limiting plate 4.

[0050] The reciprocating rotation of the third gear 23 drives the second shaft 22 to rotate, which in turn drives the triangular box 3 to rotate. This allows the chicken wings placed inside the triangular box 3 to be flipped over repeatedly, ensuring that the chicken wings are cooled evenly. The rotation of the triangular box 3 drives the circular bar 8 and the first gear 7 to revolve. Due to the setting of the gear ring 6, the two first gears 7 will also rotate on their own axis while revolving. The rotation of the two gears drives the two circular bars 8 to rotate on their own axis. The rotation of the two circular bars 8 can break off the frozen chicken wings that are stuck to the inner wall of the triangular box 3, ensuring that the chicken wings can be flipped over smoothly.

[0051] In summary, by repeating this process, chicken wings can be rapidly frozen in each refrigeration chamber using a gradient cooling method. During the rapid freezing process, the chicken wings can be repeatedly turned over in each refrigeration chamber. In addition, the round bars 8 can assist in turning the chicken wings over, preventing them from sticking to the inner wall of the triangular box 3 due to freezing and causing uneven cooling. This improves the effectiveness of the equipment.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

10. The method of using the gradient cooling quick-freezing device for frozen whole chicken wings according to claim 9, characterized in that, Includes the following steps: S1: When it is necessary to freeze whole chicken wings, first place the whole chicken wings in the triangular box (3), and then transport the triangular box (3) containing the whole chicken wings to the corresponding refrigeration chamber of the refrigeration chamber (2) by the plate conveyor belt (1) for segmented gradient cooling and quick freezing. The refrigeration chamber (2) and the refrigeration chamber are both mature existing technologies, and the refrigeration temperature of the refrigeration chamber decreases sequentially. When the plate conveyor belt (1) moves the triangular box (3) and its connecting parts together, the second gear (12) will interact with the rack (2) 8) The meshing and driving of the second gear (12) will cause the second gear (12) to rotate. At this time, the rotation of the second gear (12) will not drive the rotating rod (10) to rotate through the one-way bearing (13), but the rotation of the second gear (12) will cause the torsion spring (14) to generate torque. When the corresponding rack (28) and the second gear (12) finish meshing, the torque of the torsion spring (14) will be released. When the torque of the torsion spring (14) is released, it will cause the second gear (12) to rotate clockwise. The clockwise rotation of the second gear (12) will drive the rotating rod (10) to rotate through the one-way bearing (13). The rotating rod (10) rotates clockwise, which drives the helical gear (24) and the large pulley (16) to rotate. The clockwise rotation of the helical gear (24) first causes the first arc block (26) to move away from the helical gear (24). The movement of the first arc block (26) drives the V-shaped plate (25) to rotate. The rotation of the V-shaped plate (25) drives the second arc block (27) to move towards the helical gear (24). The second arc block (27) will be located between the adjacent helical teeth of the helical gear (24). Due to the tangential inertia of the counterweight, the rotation of the helical gear (24) will be hindered. However, the continuous release of the torque of the torsion spring (14) will cause the helical gear (24) to rotate, which in turn causes the second arc block (27) to move away from the helical gear (24). At this time, the first arc block (26) moves closer to the helical gear (24). In summary, this process repeats itself, thereby achieving the escape of the helical gear (24), reducing the rotational speed of the helical gear (24) and the rotating rod (10), and further reducing the release speed of the torque of the torsion spring (14). S2: The rotation of the large pulley (16) accelerates the rotation of the small pulley (17) via the belt (15). The rotation of the small pulley (17) drives the grooved disc (18) to rotate. The rotation of the grooved disc (18) drives the missing gear (19) and the arc rack (28)(20) to rotate. When the missing gear (19) meshes with the third gear (23), it will drive the third gear (23) to rotate 80 degrees in the forward direction. When the arc rack (28)(20) meshes with the third gear (23), it will drive the third gear (23) to rotate 80 degrees in the reverse direction. This achieves the reciprocating rotation of the third gear (23). The reciprocating rotation of the third gear (23) drives the belt to rotate. The second shaft (22) rotates, which drives the triangular box (3) to rotate, thus enabling the chicken wings placed inside the triangular box (3) to be flipped over repeatedly, ensuring that the chicken wings are cooled evenly. The rotation of the triangular box (3) drives the round bar (8) and the first gear (7) to revolve. Due to the setting of the gear ring (6), the two first gears (7) will also rotate on their own axis when they revolve. The rotation of the two gears drives the two round bars (8) to rotate on their own axis. The rotation of the two round bars (8) can break the adhesion of the chicken wings that are frozen and attached to the inner wall of the triangular box (3), ensuring that the flipping of the chicken wings can be carried out smoothly.
