Description

Technical Field

[0001] The invention relates to the technical field of freezing equipment, in particular to a high-efficiency quick-freezer for quickly locking the freshness of marine food. Background Art

[0002] In order to preserve seafood for a long time and maintain its original flavor, it is generally necessary to quick-freeze seafood. In order to achieve efficient quick freezing and lock in freshness, a quick freezer has appeared on the market. The evaporator inside the freezer is used to make the temperature inside the freezer reach the temperature required for quick freezing, and then the seafood is sent into the freezer by a conveyor belt. The conveyor belt forms two spiral towers with opposite rotation directions in the freezer through a support frame. After entering, the seafood will reach the top of one of the spiral towers and then move to the top of the other spiral tower under the drive of the conveyor belt, and then move to the bottom through the other spiral tower, and finally be sent out of the freezer. In this way, the time that seafood is placed in the freezer is prolonged, while the space occupied by the conveyor belt is reduced, forming an assembly line, which greatly improves the efficiency of the freezing process.

[0003] However, the cold air generated by the evaporator is generally blown directly into the warehouse. The space inside the warehouse is large, and the temperature in different places is lost to varying degrees. Therefore, the freezing efficiency will be affected to a certain extent, making the freshness-locking effect fail to meet expectations. Therefore, a new type of quick freezer is needed to solve this problem. Summary of the invention

[0004] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an efficient quick-freezing machine for quickly locking in the freshness of marine food.

[0006] To achieve the above purpose. The technical solution of the present invention is: a high-efficiency quick-freezing machine for quickly locking the freshness of marine food, comprising a storage body, an evaporator, two spiral towers and two rotating hubs, the two spiral towers comprising a conveyor belt and two support frames, the conveyor belt is connected end to end, and the conveyor belt is passed through the two support frames, the portion of the conveyor belt passed through the two support frames is in a spiral shape with opposite rotation directions, the two rotating hubs are rotatably connected to the storage body, and one side of the conveyor belt on the two spiral towers is respectively engaged with the two rotating hubs, the support frame comprises a spiral bracket, a plurality of vertical rods and a plurality of horizontal rods, the plurality of vertical rods are arranged around the spiral bracket, and the plurality of vertical rods are arranged around the spiral bracket. They are all fixedly connected to the storage body, several of the cross bars are respectively fixedly connected to each of the vertical bars, and each of the cross bars is fixedly connected to the spiral bracket, the conveyor belt abuts against the spiral bracket, each of the cross bars and each of the vertical bars are hollow structures, and each of the cross bars and each of the vertical bars are interconnected, each of the vertical bars are interconnected through a ring tube, each of the cross bars is provided with ventilation holes, the storage body is fixedly connected to two bellows, the air outlet on the evaporator is respectively connected to the two bellows, the two bellows are respectively connected to one of the vertical bars on the two support frames, and the outside of the support frames is wrapped with a plurality of partitions.

[0007] By adopting the above technical scheme, a relatively closed space can be formed within the range surrounded by the support frame by utilizing the partition. The cold air generated by the evaporator can be collected by the bellows and injected into the vertical rod connected to the bellows, and then transmitted to each vertical rod through the ring pipe, and then enters the space in the inner layer of the partition through the ventilation holes on the cross rod, so as to quickly freeze the items on the spiral tower. The small space formed by the partition can make the temperature near the spiral tower drop rapidly and not easily lose, thereby greatly improving the quick-freezing efficiency. At the same time, the cross rods are evenly distributed above the conveyor belt, so that the cold air can be evenly distributed on the spiral tower.

[0008] Preferably, each of the cross bars above the conveyor belt is rotatably connected with an air guide, a wind cavity is provided in the air guide, the wind cavity is connected with the ventilation hole, the air guide is provided with an outlet facing the surface of the conveyor belt, the outlet is connected with the wind cavity, and the cross bar is provided with a swing mechanism for driving the air guide to swing back and forth. The present invention utilizes the air guide to guide the cold air to act directly on the items to be frozen, thereby further improving the efficiency of quick freezing, and the air guide can swing back and forth under the drive of the swing mechanism, thereby increasing the range that the cold air can blow.

[0009] Preferably, the swing mechanism includes a transmission member and an elastic member 1, the elastic member 1 is connected between the cross bar and the air guide member, the transmission member is provided with a slide slot, the transmission member is connected to the cross bar through the slide slot, the transmission member is in contact with the conveyor belt, the transmission member is in transmission connection with the air guide member, and the cross bar is provided with a clutch mechanism for driving the transmission member to slide. The present invention utilizes the mutual contact between the transmission member and the conveyor belt, so that in the process of the conveyor belt continuously moving forward, the transmission member will be pushed and rotated by the conveyor belt under the action of friction, and the rotation will be transmitted to the air guide member, the air guide member will deform the elastic member 1 during the rotation process, the elastic member 1 can be a spring or a torsion spring, when the air guide member swings to the other side, the clutch mechanism will cause the transmission member to slide, so that the transmission member and the conveyor belt are separated from each other, at this time, the elastic member 1 releases the elastic force to drive the air guide member to reset, when the air guide member is reset, the clutch mechanism drives the transmission member to fit with the conveyor belt again, so that the air guide member starts the next swing, and the reciprocating swing of the air guide member is realized in this way.

[0010] Preferably, the clutch mechanism includes a clutch disk, a second elastic member and a driving rod, the clutch disk is provided with a swing guide groove and a reset guide groove, the depth of the swing guide groove is greater than the depth of the reset guide groove, the end of the swing guide groove coincides with the end of the reset guide groove, the head end of the swing guide groove is connected with the head end of the reset guide groove, the driving rod is slidably connected to the transmission member, the driving rod is inserted into the swing guide groove, the transmission member and the clutch disk are provided with a switching mechanism for driving the driving rod to slide, the transmission member is slidably connected to the air guide member, and the second elastic member is arranged between the transmission member and the air guide member. When the driving rod is in the initial state of the present invention, the driving rod is in the swinging guide groove. Since the depth of the swinging guide groove is greater than the reset guide groove, the transmission member can only slide along the trajectory defined by the swinging guide groove when the driving rod does not slide. When the driving rod reaches the head end of the swinging guide groove as the transmission member rotates, the switching mechanism will drive the driving rod to slide, so that the driving rod will disengage from the swinging guide groove. At this time, due to the limitation of the disengaged swinging guide groove, the transmission member will slide under the elastic force of the second elastic member, thereby separating the transmission member from the conveyor belt and allowing the driving rod to enter the reset guide groove. Then the first elastic member releases the elastic force to drive the air guide member to reset. In this process, the driving rod will also slide along the reset guide groove, and the end of the reset guide groove coincides with the end of the swinging guide groove. Therefore, under the guidance of the reset guide groove, the driving rod will return to the swinging guide groove, and at the same time drive the transmission member to overcome the elastic force 3 of the second elastic member to slide and re-fit with the conveyor belt, thereby reciprocating to form a reciprocating swing of the air guide member.

[0011] Preferably, the switching mechanism comprises an elastic member 3, a magnet 1 and a magnet 2, wherein the elastic member 3 is arranged between the driving rod and the transmission member, the magnet 1 and the magnet 2 are respectively fixedly connected to the end of the driving rod and the head end of the swing guide groove, and the magnet 1 and the magnet 2 repel each other. In the present invention, the driving rod can maintain the state of being inserted into the swing guide groove under the action of the elastic force of the elastic member 3, and when the driving rod slides to the head end of the swing guide groove, due to the repulsion of the magnet 1 and the magnet 2, the driving rod will be pushed out of the swing guide groove, and enter the reset guide groove under the action of the elastic member 2, and move along the reset guide groove under the action of the elastic force of the elastic member 1, and in the process of moving along the reset guide groove, due to the mutual distance between the magnet 1 and the magnet 2, the magnetic force will be reduced, so that the elastic member 3 releases the elastic force to make the driving rod abut against the bottom of the reset guide groove, and because there is a drop between the bottom of the reset guide groove and the swing guide groove, the driving rod will not fall into the swing guide groove in this process, but will fall into the swing guide groove again after the driving rod reaches the end, thereby achieving the effect of the driving rod switching between the two guide grooves.

[0012] Preferably, the air guide is fixedly connected to a mesh plate at the outlet. The present invention utilizes the small mesh holes of the mesh plate to reduce the wind speed of the cold air when it is blown out of the outlet, thereby preventing the loss of moisture from the articles, and at the same time utilizes the porous nature of the mesh plate to expand the range of the cold air when it is blown out.

[0013] Preferably, the bellows is provided with an exhaust port. The present invention utilizes the exhaust port to exhaust excess cold air into the storage body, thereby accelerating the temperature drop inside the entire storage body.

[0014] Preferably, the bellows is provided with a limiting mechanism for limiting the air flow from the air outlet. The present invention utilizes the limiting mechanism to increase the pressure required when the cold air is discharged from the air outlet, so that most of the cold air is discharged through the vent.

[0015] Preferably, the limiting mechanism comprises a cover plate and an elastic member 4, the cover plate is slidably connected to the bellows, and the elastic member 4 is arranged between the cover plate and the bellows. The present invention utilizes the elastic force of the elastic member 4 to provide resistance when the cover plate slides, thereby achieving the effect of increasing the resistance of the air outlet.

[0016] Preferably, a magnetic sheet is provided inside the partition, and the partition is fixed to the support frame by the attraction of the magnetic sheet. The present invention utilizes the mutual attraction between the partition and the magnetic sheet to fix the partition, and also makes the partition easy to disassemble, so as to facilitate the cleaning and maintenance of the spiral tower.

[0017] In summary, the beneficial effects of the present invention are:

[0018] 1. The small space formed by the partition allows the temperature near the spiral tower to drop quickly and is not easy to lose, thereby greatly improving the quick-freezing efficiency. At the same time, the cross bars are distributed everywhere above the conveyor belt, which can make the cold air evenly distributed on the spiral tower.

[0019] 2. The air guide can be used to guide the cold air to act directly on the items to be frozen, thereby further improving the efficiency of quick freezing. The air guide can swing back and forth under the drive of the swing mechanism, thereby increasing the range where the cold air can blow.

[0040] like Figure 1-2 As shown, a high-efficiency quick-freezing machine for quickly locking fresh marine food comprises a storage body 1, an evaporator 2, two spiral towers 6 and two rotating hubs 5. The two spiral towers 6 comprise a conveyor belt 3 and two support frames 4. The conveyor belt 3 is connected end to end, and a portion of the conveyor belt 3 is passed through the two support frames 4. The portion of the conveyor belt 3 passed through the two support frames 4 is in a spiral shape with opposite rotation directions. The two rotating hubs 5 are both rotatably connected to the storage body 1, and one side of the conveyor belt 3 on the two spiral towers 6 is respectively engaged with the two rotating hubs 5. The supporting frame 4 comprises a spiral bracket 7, a plurality of vertical rods 8 and a plurality of horizontal rods 9. The plurality of vertical rods 8 are arranged around the spiral bracket 7, and the plurality of vertical rods 8 are all connected to the storage body 1. The body 1 is fixedly connected, a plurality of cross bars 9 are respectively fixedly connected to each vertical bar 8, and each cross bar 9 is fixedly connected to the spiral bracket 7, the conveyor belt 3 abuts against the spiral bracket 7, each cross bar 9 and each vertical bar 8 are hollow structures, and each cross bar 9 and each vertical bar 8 are interconnected, each vertical bar 8 is interconnected through a ring tube 10, and each cross bar 9 is provided with a ventilation hole 11, the storage body 1 is fixedly connected with two bellows 12, the air outlet on the evaporator 2 is respectively connected to the two bellows 12, the two bellows 12 are respectively connected to one of the vertical bars 8 on the two support frames 4, and the outside of the support frame 4 is wrapped with a plurality of partitions 13.

[0041] By adopting the above technical scheme, a relatively closed space can be formed within the range surrounded by the support frame 4 by utilizing the partition 13, and the cold air generated by the evaporator 2 can be collected by the bellows 12 and injected into the vertical rod 8 connected to the bellows 12, and then transmitted to each vertical rod 8 through the ring pipe 10, and then enters the space in the inner layer of the partition 13 through the ventilation holes 11 on the cross bar 9, so as to quickly freeze the items on the spiral tower 6. The small space formed by the partition 13 can enable the temperature near the spiral tower 6 to drop rapidly and is not easy to lose, thereby greatly improving the quick-freezing efficiency. At the same time, the cross bars 9 are distributed at various places above the conveyor belt 3, so that the cold air can be evenly distributed on the spiral tower 6.

[0042] like Figure 2-3 As shown, each cross bar 9 above the conveyor belt 3 is rotatably connected with an air guide 14, an air cavity 15 is provided in the air guide 14, the air cavity 15 is connected with the ventilation hole 11, an outlet facing the surface of the conveyor belt 3 is provided in the air guide 14, the outlet is connected with the air cavity 15, and the cross bar 9 is provided with a swing mechanism for driving the air guide 14 to swing back and forth. The air guide 14 can be used to guide the cold air to act directly on the items to be frozen, thereby further improving the efficiency of quick freezing, and the air guide 14 can swing back and forth under the drive of the swing mechanism, thereby increasing the range where the cold air can blow.

[0043] like Figure 4 As shown, the swing mechanism includes a transmission member 16 and an elastic member 17, the elastic member 17 is connected between the cross bar 9 and the air guide member 14, the transmission member 16 is provided with a slide groove 18, the transmission member 16 is rotationally and slidably connected with the cross bar 9 through the slide groove 18, the transmission member 16 abuts against the conveyor belt 3, the transmission member 16 is transmission-connected with the air guide member 14, and the cross bar 9 is provided with a clutch mechanism that drives the transmission member 16 to slide by the rotation of the transmission member 16. By utilizing the mutual contact between the transmission member 16 and the conveyor belt 3, as the conveyor belt 3 continues to move forward, the transmission member 16 will be pushed and rotated by the conveyor belt 3 under the action of friction, and the rotation will be transmitted to the air guide member 14. During the rotation of the air guide member 14, the elastic member 17 will be deformed. The elastic member 17 can be a spring or a torsion spring. When the air guide member 14 swings to the other side, the clutch mechanism will cause the transmission member 16 to slide, so that the transmission member 16 and the conveyor belt 3 are separated from each other. At this time, the elastic member 17 releases the elastic force to drive the air guide member 14 to reset. When the air guide member 14 is reset, the clutch mechanism drives the transmission member 16 to fit with the conveyor belt 3 again, so that the air guide member 14 starts the next swing. In this way, the reciprocating swing of the air guide member 14 is achieved.

[0044] like Figure 4-6As shown, the clutch mechanism includes a clutch disk 19, an elastic member 20 and a drive rod 21. The clutch disk 19 is provided with a swing guide groove 22 and a reset guide groove 23. The depth of the swing guide groove 22 is greater than that of the reset guide groove 23. The end of the swing guide groove 22 coincides with the end of the reset guide groove 23. The head end of the swing guide groove 22 is connected to the head end of the reset guide groove 23. The drive rod 21 is slidably connected to the transmission member 16. The drive rod 21 is inserted into the swing guide groove 22. A switching mechanism for driving the drive rod 21 to slide is provided on the transmission member 16 and the clutch disk 19. The transmission member 16 is slidably connected to the air guide member 14. The elastic member 20 is provided between the transmission member 16 and the air guide member 14. In the initial state, the driving rod 21 is in the swing guide groove 22. Since the depth of the swing guide groove 22 is greater than the reset guide groove 23, when the driving rod 21 does not slide, the transmission member 16 can only slide along the trajectory defined by the swing guide groove 22. When the driving rod 21 reaches the head end of the swing guide groove 22 as the transmission member 16 rotates, the switching mechanism drives the driving rod 21 to slide, so that the driving rod 21 is separated from the swing guide groove 22. At this time, due to the restriction of the separated swing guide groove 22, the transmission member 16 slides under the elastic force of the elastic member 20, so that The transmission member 16 is separated from the conveyor belt 3, and the driving rod 21 enters the reset guide groove 23. Then the elastic member 17 releases the elastic force to drive the air guide member 14 to reset. In this process, the driving rod 21 will also slide along the reset guide groove 23, and the end of the reset guide groove 23 coincides with the end of the swing guide groove 22. Therefore, under the guidance of the reset guide groove 23, the driving rod 21 will return to the swing guide groove 22, and at the same time drive the transmission member 16 to overcome the elastic force 3 of the elastic member 20 to slide and re-fit with the conveyor belt 3, so as to reciprocate and form a reciprocating swing of the air guide member 14.

[0045] like Figure 4-7As shown, the switching mechanism includes an elastic member 3 24, a magnet 1 25 and a magnet 2 26. The elastic member 3 24 is arranged between the driving rod 21 and the transmission member 16. The magnet 1 25 and the magnet 2 26 are respectively fixedly connected to the end of the driving rod 21 and the head end of the swing guide groove 22. The magnet 1 25 and the magnet 2 26 repel each other. Under the action of the elastic force of the elastic member three 24, the driving rod 21 can remain inserted into the swing guide groove 22. When the driving rod 21 slides to the head end of the swing guide groove 22, due to the repulsion between the magnet one 25 and the magnet two 26, the driving rod 21 will be pushed out of the swing guide groove 22, and enter the reset guide groove 23 under the action of the elastic member two 20, and move along the reset guide groove 23 under the elastic force of the elastic member one 17. In the process of moving along the reset guide groove 23, due to the mutual distance between the magnet one 25 and the magnet two 26, the magnetic force will be reduced, so that the elastic member three 24 releases the elastic force and the driving rod 21 will abut against the bottom of the reset guide groove 23. Since there is a drop between the bottom of the reset guide groove 23 and the swing guide groove 22, the driving rod 21 will not fall into the swing guide groove 22 during this process, but will fall into the swing guide groove 22 again after the driving rod 21 reaches the end, thereby achieving the effect of the driving rod 21 switching between the two guide grooves.

[0046] like Figure 4 As shown, the air guide 14 is fixedly connected with a mesh plate 27 at the outlet. The small mesh holes of the mesh plate 27 can reduce the wind speed of the cold air when it blows out of the outlet, thereby preventing the loss of moisture from the articles, and at the same time, the porous nature of the mesh plate 27 also expands the range of the cold air when it blows out.

[0047] like Figure 8 As shown, the wind box 12 is provided with an exhaust port 28. The exhaust port 28 can be used to exhaust excess cold air into the storage body 1, thereby accelerating the temperature drop inside the entire storage body 1.

[0048] like Figure 8 As shown, the bellows 12 is provided with a limiting mechanism to limit the air outflow from the exhaust port 28. The limiting mechanism can increase the pressure required for the cold air to be discharged from the exhaust port 28, so that most of the cold air is discharged through the vents.

[0049] like Figure 8 As shown, the limiting mechanism includes a cover plate 29 and an elastic member 4 30. The cover plate 29 is slidably connected to the bellows 12. The elastic member 4 30 is arranged between the cover plate 29 and the bellows 12. The elastic force of the elastic member 4 30 is used to provide resistance when the cover plate 29 slides, thereby increasing the resistance of the exhaust port 28.

[0050] like Fig. 9As shown, the partition 13 is provided with a magnetic sheet 31 on the inner side of the ring tube 10, and the partition 13 is fixed to the support frame 4 by the attraction of the magnetic sheet 31. The partition 13 is fixed by the mutual attraction between the partition 13 and the magnetic sheet 31, and the partition 13 is also easy to disassemble, so that the spiral tower 6 can be easily cleaned and maintained.

[0051] It should be noted that many specific details are described in the above description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
