[0001] The present invention relates to the technical field of quick-freezing of surimi products, and in particular to a quick-freezing device for surimi products. Background Art

[0002] During the production process of surimi products, it is necessary to quickly freeze the surimi products. Generally, the surimi products are immersed in liquid nitrogen to achieve the purpose of rapid freezing.

[0003] Chinese Patent with the publication number CN111879042B discloses a rapid freezing device for surimi products, including a liquid nitrogen storage tank filled with liquid nitrogen. On both sides of the top of the liquid nitrogen storage tank, there are support frames. A driving turntable is installed between the support frames. A transmission column is installed inside the driving turntable, and the transmission column penetrates through the driving turntable. A driving motor is installed on one of the support frames.

[0017] The present invention provides a quick-freezing device for surimi products through improvement. Compared with the prior art, the following improvements and advantages are achieved:

[0018] First: Through the arrangement of the quick-freezing mechanism of the present invention, the motor drives the rotating wheel and the rotating sleeve to rotate through the driving shaft and the driving wheel. The rotation of the rotating sleeve drives the fixed frame, the fixed rod, the movable sleeve and the fixed box to rotate. When the rotating wheel contacts the arc plate, the rotating wheel moves and rotates on the arc plate. The rotation of the rotating wheel drives the cylindrical rod to perform circular rotation. The rotation of the cylindrical rod drives the movable rod to perform reciprocating movement through the L-shaped connecting rod. The movement of the movable rod drives the flat plate and the fixed piece to perform reciprocating movement. The fixed piece and the flat plate move upward. The fixed piece can cover the top of the net box. The upward movement of the flat plate pushes the liquid nitrogen above the flat plate to contact the bottom of the net box through the strip-shaped holes, so that the bottom of the net box can fully contact the liquid nitrogen, improving the freezing effect of the liquid nitrogen on the surimi products.

[0019] Second: When the fixed column contacts the hypotenuse of the pressing plate in the present invention, with the continuous rotation of the fixed column, the pressing plate squeezes the fixed column to move downward. The movement of the fixed column drives the movable sleeve and the fixed box to move downward. The downward movement of the movable sleeve drives the connecting spring to stretch and undergo elastic deformation, so that the fixed box enters the liquid storage tank, and the liquid nitrogen in the liquid storage tank freezes the surimi products, and thus the surimi products can be frozen by being placed in the liquid nitrogen.

[0020] Third: When the fixed column contacts the hypotenuse of the pressing plate in the present invention, the fixed column first drives the pressing plate to move upward. The movement of the pressing plate drives the support and the sliding cap to move. The movement of the sliding cap drives the telescopic spring to stretch and undergo elastic deformation. The movement of the support drives the mounting rod and the stirring plate to move upward. When the fixed column moves away from the pressing plate, the telescopic spring drives the sliding cap, the support, the pressing plate, the mounting rod and the stirring plate to reset, so that the stirring plate can stir the liquid nitrogen to make the liquid nitrogen more uniform.

[0021] Fourth: When the weight of the surimi product increases in the present invention, the sliding rod moves downward. The movement of the sliding rod drives the installation spring to stretch and undergo elastic deformation. The movement of the sliding rod drives the extrusion block to move downward. The movement of the extrusion block drives the mounting plate and the movable plate away from the sliding rod. The movement of the movable plate drives the drive shaft, the motor, and the drive wheel to move. At the same time, the movement of the movable plate drives the extrusion spring to compress and undergo elastic deformation. The downward movement of the sliding rod drives the rotating wheel to move downward. Since the diameter of the rotating wheel gradually increases from bottom to top, the rotation speed of the drive wheel driving the rotating wheel and the rotating sleeve decreases, so that the surimi product stays in the liquid nitrogen for a longer time to increase the contact time, thereby improving the freezing effect on the surimi product.

[0032] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides a quick-freezing device for surimi products by improvement. The technical solution of the present invention is as follows:

[0034] As Figures 1 to 7 shown, the embodiment of the present invention provides a quick-freezing device for surimi products, including a liquid storage tank 1. A fixed plate 11 is fixedly connected to the liquid storage tank 1. A slide bar 2 is slidably connected to the fixed plate 11. A rotating sleeve 21 is rotatably connected to the slide bar 2. The device further includes:

[0035] A quick-freezing mechanism, which is located on the fixed plate 11;

[0036] The quick-freezing mechanism includes a driving unit, a lifting unit, and a reciprocating unit. The lifting unit includes two fixing frames 22 fixedly connected to the rotating sleeve 21. One end of each of the two fixing frames 22 is fixedly connected to a fixing rod 23. The bottom ends of the two fixing rods 23 are both slidably sleeved with movable sleeves 24. A connecting spring 28 is provided in each of the two movable sleeves 24. The two ends of the connecting spring 28 are fixedly connected to the fixing rod 23 and the movable sleeve 24 respectively. The bottom ends of the two movable sleeves 24 are both fixedly connected to a fixing box 25. A fixing column 35 is fixedly connected to each of the two movable sleeves 24. The top ends of the sliding rods 2 are both slidably connected to a sliding cap 4. A bracket 41 is fixedly connected to the sliding cap 4. One end of the bracket 41 is fixedly connected to a pressing plate 42. One of the fixing columns 35 is in contact with the bottom of the pressing plate 42. A telescopic spring 44 is provided in the sliding cap 4. The two ends of the telescopic spring 44 are fixedly connected to the sliding rod 2 and the sliding cap 4 respectively. An arc-shaped plate 43 is fixedly connected to the pressing plate 42. Through the setting of the lifting unit, the driving unit drives the rotating sleeve 21 to rotate. The rotation of the rotating sleeve 21 drives the fixing frames 22, the fixing rods 23, the movable sleeves 24, and the fixing boxes 25 to rotate. When the fixing column 35 contacts the hypotenuse of the pressing plate 42, with the continuous rotation of the fixing column 35, the pressing plate 42 is caused to press the fixing column 35 to move downward. The movement of the fixing column 35 drives the movable sleeve 24 and the fixing box 25 to move downward. The downward movement of the movable sleeve 24 drives the connecting spring 28 to stretch and undergo elastic deformation, so that the fixing box 25 enters the liquid storage tank 1, and the liquid nitrogen in the liquid storage tank 1 freezes the surimi products, and thus the surimi products can be placed in the liquid nitrogen for freezing.

[0037] Furthermore, the reciprocating unit includes fixing blocks 3 respectively and fixedly connected to two movable sleeves 24. Movable rods 31 are slidably connected to both of the two fixing blocks 3. The two movable rods 31 are respectively slidably connected to two fixing boxes 25. The bottom ends of the two movable rods 31 are fixedly connected with flat plates 32. A group of fixing pieces 33 are fixedly connected to the top of both of the two flat plates 32. The ends of two fixing columns 35 are fixedly connected with runners 36. Cylindrical rods 37 are eccentrically fixedly connected to both of the two runners 36. The ends of the two cylindrical rods 37 are rotatably sleeved with L-shaped connecting rods 38. The bottom ends of the two L-shaped connecting rods 38 are respectively rotatably connected to the top ends of the two movable rods 31. One of the runners 36 is in contact with the bottom of the arc-shaped plate 43. A group of strip-shaped holes 26 are opened on both of the two fixing boxes 25. The two groups of fixing pieces 33 respectively extend into the two groups of strip-shaped holes 26. Through the setting of the reciprocating unit, when the runner 36 contacts the arc-shaped plate 43, the runner 36 moves and rotates on the arc-shaped plate 43. The rotation of the runner 36 drives the cylindrical rod 37 to perform circular rotation. The rotation of the cylindrical rod 37 drives the movable rod 31 to perform reciprocating movement through the L-shaped connecting rod 38. The movement of the movable rod 31 drives the flat plate 32 and the fixing piece 33 to perform reciprocating movement. When the fixing piece 33 and the flat plate 32 move upward, the fixing piece 33 can cover the top of the net box. The upward movement of the flat plate 32 pushes the liquid nitrogen above the flat plate 32 to contact the bottom of the net box through the strip-shaped hole 26, so that the bottom of the net box can fully contact with the liquid nitrogen, improving the freezing effect of the liquid nitrogen on the surimi products.

[0038] Furthermore, two groups of tapered holes 27 are opened on both of the two fixing boxes 25. The two groups of tapered holes 27 are symmetric with respect to a group of fixing pieces 33. Through the setting of the tapered holes 27, the liquid nitrogen in the liquid storage tank 1 enters the space where the flat plate 32 is placed through the multiple tapered holes 27.

[0039] Furthermore, return springs 34 are sleeved on both of the two movable rods 31. The two ends of the two return springs 34 are respectively fixedly connected with the fixing block 3 and the movable rod 31. Through the setting of the return springs 34, when the runner 36 moves away from the arc-shaped plate 43, the return springs 34 can drive the movable rod 31 and the flat plate 32 to reset.

[0040] Furthermore, an installation rod 45 is fixedly connected to the support 41, and a stirring plate 46 is fixedly connected to the bottom end of the installation rod 45. The stirring plate 46 is located inside the liquid storage tank 1. Through the arrangement of the stirring plate 46, when the fixed column 35 contacts the hypotenuse of the pressing plate 42, as the fixed column 35 continues to rotate, the fixed column 35 first drives the pressing plate 42 to move upward. The movement of the pressing plate 42 drives the support 41 and the sliding cap 4 to move. The movement of the sliding cap 4 drives the telescopic spring 44 to stretch and undergo elastic deformation. The movement of the support 41 drives the installation rod 45 and the stirring plate 46 to move upward. When the bottom end of the sliding cap 4 moves to the top end of the sliding rod 2, the sliding cap 4 stops moving. When the fixed column 35 moves away from the pressing plate 42, the telescopic spring 44 drives the sliding cap 4, the support 41, the pressing plate 42, the installation rod 45, and the stirring plate 46 to reset, enabling the stirring plate 46 to stir the liquid nitrogen and making the liquid nitrogen more uniform.

[0041] Furthermore, the driving unit includes a movable plate 12 slidably connected to the fixed plate 11. A mounting plate 14 is fixedly connected to the bottom of the movable plate 12. A motor 15 is fixedly connected to the mounting plate 14. The output end of the motor 15 is connected to a driving shaft 16 through a coupling. A driving wheel 17 is fixedly connected to the top end of the driving shaft 16. A rotating wheel 18 is fixedly sleeved on the rotating sleeve 21. The rotating wheel 18 is in contact with the driving wheel 17. Through the arrangement of the driving unit, the motor 15 drives the driving shaft 16 and the driving wheel 17 to rotate. The rotation of the driving wheel 17 drives the rotating wheel 18 and the rotating sleeve 21 to rotate. The rotation of the rotating sleeve 21 drives the fixed frame 22, the fixed rod 23, the movable sleeve 24, and the fixed box 25 to rotate, realizing the rotation of the fixed box 25.

[0042] Furthermore, a mounting spring 5 is sleeved on the sliding rod 2. Two ends of the mounting spring 5 are fixedly connected to the sliding rod 2 and the fixing plate 11 respectively. A pressing block 51 is fixedly connected to the bottom end of the sliding rod 2. A connecting plate 52 is fixedly connected to the mounting plate 14. The pressing block 51 is connected to the connecting plate 52. A pressing spring 13 is arranged in the fixing plate 11. Two ends of the pressing spring 13 are fixedly connected to the fixing plate 11 and the movable plate 12 respectively. Through the arrangement of the mounting spring 5, when the weight of the surimi product increases, the sliding rod 2 moves downward. The movement of the sliding rod 2 drives the mounting spring 5 to stretch and undergo elastic deformation. The movement of the sliding rod 2 drives the pressing block 51 to move downward. The movement of the pressing block 51 drives the mounting plate 14 and the movable plate 12 to move away from the sliding rod 2. The movement of the movable plate 12 drives the drive shaft 16, the motor 15 and the drive wheel 17 to move. At the same time, the movement of the movable plate 12 drives the pressing spring 13 to be compressed and undergo elastic deformation. The downward movement of the sliding rod 2 drives the rotating wheel 18 to move downward. Since the diameter of the rotating wheel 18 gradually increases from bottom to top, the rotational speed of the drive wheel 17 driving the rotating wheel 18 and the rotating sleeve 21 is reduced, so that the surimi product stays in the liquid nitrogen for a longer time to increase the contact time, thereby improving the freezing effect on the surimi product.

[0043] Specific implementation steps: Start the motor 15 to drive the drive shaft 16 and the drive wheel 17 to rotate. The rotation of the drive wheel 17 drives the rotation of the rotating wheel 18 and the rotating sleeve 21. The rotation of the rotating sleeve 21 drives the rotation of the fixed frame 22, the fixed rod 23, the movable sleeve 24 and the fixed box 25. When the fixed box 25 rotates to the position of the fixed plate 11, place the fish cake product-containing net box in the fixed box 25. When the fixed box 25 rotates into the liquid storage tank 1, the fish cake products in the net box are frozen. The rotation of the movable sleeve 24 drives the rotation of the fixed column 35. When the fixed column 35 contacts the hypotenuse of the pressing plate 42, as the fixed column 35 continues to rotate, the fixed column 35 first drives the pressing plate 42 to move upward. The movement of the pressing plate 42 drives the bracket 41 and the sliding cap 4 to move. The movement of the sliding cap 4 drives the stretching and elastic deformation of the telescopic spring 44. The movement of the bracket 41 drives the mounting rod 45 and the stirring plate 46 to move upward. When the bottom end of the sliding cap 4 moves to the top end of the sliding rod 2, the sliding cap 4 stops moving. Then the pressing plate 42 presses the fixed column 35 to move downward. The movement of the fixed column 35 drives the movable sleeve 24 and the fixed box 25 to move downward. The downward movement of the movable sleeve 24 drives the stretching and elastic deformation of the connecting spring 28, so that the fixed box 25 enters the liquid storage tank 1, and the liquid nitrogen in the liquid storage tank 1 freezes the fish cake products. Thus, the fish cake products can be frozen in liquid nitrogen. When the rotating wheel 36 contacts the arc-shaped plate 43, the rotating wheel 36 moves and rotates on the arc-shaped plate 43. The rotation of the rotating wheel 36 drives the cylindrical rod 37 to rotate in a circle. The rotation of the cylindrical rod 37 drives the movable rod 31 to move back and forth through the L-shaped connecting rod 38. The movement of the movable rod 31 drives the flat plate 32 and the fixing piece 33 to move back and forth. When the fixing piece 33 and the flat plate 32 move upward, the fixing piece 33 can cover the top of the net box. The upward movement of the flat plate 32 pushes the liquid nitrogen above the flat plate 32 to contact the bottom of the net box through the strip-shaped holes 26, so that the bottom of the net box can fully contact the liquid nitrogen, improving the freezing effect of the liquid nitrogen on the fish cake products. When the flat plate 32 and the fixing piece 33 move downward, the liquid nitrogen in the liquid storage tank 1 enters the space where the flat plate 32 is placed through a plurality of tapered holes 27. When the fixed column 35 moves out from the other end of the pressing plate 42, the connecting spring 28 drives the movable sleeve 24 and the fixed box 25 to quickly reset. Under the action of the connecting spring 28, the fixed box 25 vibrates, so that the liquid nitrogen on the fixed box 25 can be shaken off and fall into the liquid storage tank 1, thus achieving the purpose of saving resources. At the same time, the telescopic spring 44 drives the sliding cap 4, the bracket 41, the pressing plate 42, the mounting rod 45 and the stirring plate 46 to reset, so that the stirring plate 46 can stir the liquid nitrogen to make the liquid nitrogen more uniform. When the weight of the fish cake products increases, the sliding rod 2 moves downward. The movement of the sliding rod 2 drives the stretching and elastic deformation of the mounting spring 5. The movement of the sliding rod 2 drives the pressing block 51 to move downward. The movement of the pressing block 51 drives the mounting plate 14 and the movable plate 12 to move away from the sliding rod 2. The movement of the movable plate 12 drives the drive shaft 16, the motor 15 and the drive wheel 17 to move.Meanwhile, the moving of the movable plate 12 drives the compression of the extrusion spring 13 and causes elastic deformation. The downward movement of the sliding rod 2 drives the downward movement of the rotating wheel 18. Since the diameter of the rotating wheel 18 gradually increases from bottom to top, the driving wheel 17 drives the rotating speed of the rotating wheel 18 and the rotating sleeve 21 to decrease, so that the time for the surimi product to stay in the liquid nitrogen increases to increase the contact time, thereby improving the freezing effect on the surimi product.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
