Description

Technical Field

[0001] The utility model relates to the technical field of air knives, in particular to an adjustable air knife for a tunnel quick-freezing machine. Background Art

[0002] In the field of quick-frozen food processing, tunnel quick freezers are an important equipment widely used in the quick freezing process of various foods. The air knife in the tunnel quick freezer, as a key blowing component, has a vital impact on the quick freezing effect of food. However, the existing tunnel quick freezer air knife design has some limitations, especially in terms of height and angle adjustment.

[0003] First, the existing wind knives of tunnel quick freezers are usually fixed in a specific position and cannot be adjusted in height. This means that the distance between the wind knife and the food is fixed and cannot be flexibly adjusted according to the thickness, shape or freezing requirements of the food. This fixed height setting may lead to uneven blowing effect, and some foods may freeze too fast or too slowly, thus affecting the freezing quality and efficiency. Secondly, the existing wind knives are also insufficient in angle adjustment. Since the angle of the wind knife is fixed, it cannot be precisely adjusted according to the placement direction or freezing requirements of the food. This may cause the blowing direction to deviate from the surface of the food, and it is impossible to effectively remove moisture from the surface of the food or achieve the ideal freezing effect. At the same time, the fixed angle also limits the adaptability of the wind knife in different application scenarios, which limits its scope of application. Utility Model Content

[0004] The utility model aims to provide an adjustable wind knife for a tunnel quick-freezing machine to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tunnel quick freezer adjusting wind knife, comprising a tunnel quick freezer, two electric telescopic rods, a connecting plate, two brackets, a wind knife, an air intake pipe, a bearing and an angle adjustment structure, the two electric telescopic rods are arranged at the top of the tunnel quick freezer casing, the connecting plate is arranged at the driving ends of the two electric telescopic rods, the two brackets are arranged at the bottom of the connecting plate, both of the two brackets are provided with mounting holes, bearings are arranged in the mounting holes, the inner ring of the bearing is interference fit with the outer wall of the wind knife, the air intake pipe is fixed through the top of the tunnel quick freezer casing, one end of the air intake pipe is connected to one end of the wind knife, and the middle section of the air intake pipe is a retractable corrugated hose, and the wind knife is provided with an angle adjustment structure.

[0006] Preferably, the angle adjustment structure includes a support seat, a motor, a first gear and a second gear, the support seat is arranged at the bottom of the connecting plate, the motor is arranged on the support seat, the first gear is arranged at the driving end of the motor, the second gear is arranged on the outer wall of the wind knife, and the first gear is meshed with the second gear.

[0007] Preferably, the diameter of the first gear is smaller than the diameter of the second gear.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model realizes the height adjustment function of the air knife through the setting of the cylinder and the bracket, so that the air knife can be accurately adjusted in the vertical direction according to different food or process requirements. This improvement effectively solves the problem of uneven blowing effect caused by the fixed height of the traditional air knife, ensures that the food can be evenly cooled during the freezing process, and improves the freezing quality. At the same time, the rotation adjustment of the air knife on the bracket is realized through the coordinated use of the motor, the first gear and the second gear in the angle adjustment structure, that is, the flexible adjustment of the air knife angle. This multi-angle adjustment function allows the air knife to be accurately adjusted according to the placement direction, shape or freezing requirements of the food, thereby ensuring that the blowing direction always maintains the best angle with the food surface, and improves the freezing efficiency. In summary, the utility model realizes multiple adjustments of the air knife in height and angle through the coordinated use of the cylinder, the bracket, the motor, the gear and other mechanisms. This multi-angle adjustment design not only improves the freezing quality and efficiency, but also enhances the flexibility and adaptability of the quick freezer, so that it can better meet the needs of different application scenarios.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] See also Figure 1-2 The utility model provides an adjustable wind knife for a tunnel quick freezer, comprising a tunnel quick freezer 1, two electric telescopic rods 2, a connecting plate 3, two brackets 4, a wind knife 5, an air inlet pipe 6, a bearing 7 and an angle adjustment structure. The two electric telescopic rods 2 are arranged at the top of the tunnel quick freezer 1 casing, the connecting plate 3 is arranged at the driving ends of the two electric telescopic rods 2, the two brackets 4 are arranged at the bottom of the connecting plate 3, the two brackets 4 are both provided with mounting holes, the mounting holes are provided with bearings 7, the inner ring of the bearing 7 is interference fit with the outer wall of the wind knife 5, the air inlet pipe 6 is fixedly passed through the top of the tunnel quick freezer 1 casing, one end of the air inlet pipe 6 is connected to one end of the wind knife 5, and the middle section of the air inlet pipe 6 is a retractable corrugated hose, and the wind knife 5 is provided with an angle adjustment structure.

[0014] Specifically, the angle adjustment structure includes a support seat 8, a motor 9, a first gear 10 and a second gear 11. The support seat 8 is arranged at the bottom of the connecting plate 3, the motor 9 is arranged on the support seat 8, the first gear 10 is arranged at the driving end of the motor 9, and the second gear 11 is arranged on the outer wall of the wind knife 5. The first gear 10 is meshed with the second gear 11.

[0015] Specifically, the diameter of the first gear 10 is smaller than the diameter of the second gear 11 .

[0016] Working principle: When the height of the wind knife 5 needs to be adjusted, the connecting plate 3 and the bracket 4 and the wind knife 5 below it can be driven to move up and down as a whole by controlling the telescopic length of the electric telescopic rod 2. Since the electric telescopic rod 2 has precise control capabilities, the height of the wind knife 5 can be precisely adjusted. When the angle of the wind knife 5 needs to be adjusted, the motor 9 starts and drives the first gear 10 to rotate. Since the first gear 10 is meshed with the second gear 11, the second gear 11 will rotate with the rotation of the first gear 10. Since the second gear 11 is fixedly mounted on the outer wall of the wind knife 5, the wind knife 5 will adjust its angle with the rotation of the second gear 11. In this way, the blowing direction of the wind knife 5 can be precisely controlled to keep the best angle with the food surface, thereby optimizing the freezing effect. The design of the air inlet pipe 6 also fully considers the need for adjusting the angle of the wind knife 5. One end of the air inlet pipe 6 is connected to one end of the wind knife 5 to ensure that the cold air can smoothly enter the wind knife 5 and blow out. The middle section of the air inlet pipe 6 adopts a retractable corrugated hose design. This design allows the air inlet pipe 6 to have a certain degree of flexibility and elasticity, and to be able to expand and contract and bend accordingly as the angle of the wind knife 5 changes without being subject to excessive restrictions or constraints.

[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
