[0025] 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.

[0026] See also Figure 1-5 The utility model provides a technical solution for a tower-type quick-freezing device for dumplings: it includes a supporting frame 1, a central drum is rotatably arranged in the supporting frame 1, a driving motor connected to the central drum is arranged on the top of the supporting frame 1, and is used to drive the central drum to rotate, a spiral frame 2 is fixedly connected in the supporting frame 1, a spiral conveying mesh belt 3 with a circulating transmission is arranged on the spiral frame 2, and the spiral conveying mesh belt 3 is connected to the central drum, so that the driving motor drives the spiral conveying mesh belt 3 to perform a spiral ascending motion along the spiral trajectory of the spiral frame 2 through the central drum.

[0027] The spiral conveyor mesh belt 3 is provided with interconnected cold air transmission channels, through which cold air can be transmitted to the surface of the spiral conveyor mesh belt 3, so that external cold air can circulate on the spiral conveyor mesh belt 3 and move with the spiral conveyor mesh belt 3, so that the cold air can continuously freeze the dumplings on the spiral conveyor mesh belt 3, thereby reducing the freezing time and improving the freezing efficiency.

[0028] Each cold air transmission channel is provided with an anti-leakage component. By providing the anti-leakage component, the on and off of each cold air transmission channel can be controlled to prevent a large amount of cold air from overflowing when the cold air is transported through the cold air transmission channel, resulting in a low refrigeration effect.

[0029] A docking drive switch 6 connected to an external refrigeration mechanism is provided on the support frame 1. The refrigeration mechanism is used for refrigeration. This is a prior art and will not be elaborated here. The refrigeration mechanism can provide cold air to the docking drive switch 6. The docking drive switch 6 is magnetically connected to the anti-leakage component. When the spiral conveyor mesh belt 3 moves on the spiral frame 2, when one of the cold air transmission channels corresponds to the docking drive switch 6, the docking drive switch 6 can use magnetism to control the activation of the corresponding anti-leakage component, so that the docking drive switch 6 is connected to the corresponding cold air transmission channel, so as to transfer the cold air generated by the refrigeration mechanism to the spiral conveyor mesh belt 3 through the cold air transmission channel for circulation.

[0030] Specifically, an installation cavity is provided in the spiral conveyor mesh belt 3, and the anti-leakage component includes an elastic member 51 fixedly connected in the installation cavity. The elastic member 51 can be a compression spring. The side wall of the installation cavity is provided with a through hole 52 connected to the cold air transmission channel. A sealing ball 53 for sealing the through hole 52 is fixedly connected to one end of the elastic member 51. The elastic member can continuously provide force to the sealing ball 53 in the direction of the cold air transmission channel, so that under normal conditions, that is, when the anti-leakage component is not aligned with the docking drive switch 6, the sealing ball 53 can block the through hole 52 to prevent the cold air from overflowing in large quantities through other cold air transmission channels when the cold air is transported through one of the cold air transmission channels, resulting in a low refrigeration effect.

[0031] When the docking drive switch 6 is opposite to one of the anti-leakage components, the docking drive switch 6 can control the blocking ball 53 to move toward one end close to the docking drive switch 6 through magnetism, and squeeze the elastic member 51 .

[0032] Specifically, the installation cavity is a rectangular cavity, and an air passage is formed between the inner walls of the rectangular cavity of the sealing ball 53. When the sealing ball 53 is attracted by magnetism and moves in the direction of the docking drive switch 6, the sealing ball 53 will release the blockage of the through hole 52, and the cold air can be transmitted through the air passage and flow to the cold air transmission channel through the through hole 52, thereby finally realizing the freezing of the dumplings on the spiral conveyor mesh belt 3.

[0033] A limiting groove 54 for the sealing ball 53 to slide is provided in the installation cavity, which plays a limiting role, so that the sealing ball 53 moves under the restriction of the limiting groove 54, ensuring that the sealing ball 53 can accurately block the through hole 52.

[0034] Specifically, the inner wall of the installation cavity is provided with an arc groove 55 connected with the through hole 52. The arc groove 55 matches the outer wall shape of the blocking ball 53 to improve the blocking effect. A sealing ring 56 is fixed to the inner wall of the arc groove 55 to further improve the blocking effect.

[0035] Specifically, the docking drive switch 6 includes a docking cover 61, which is connected to the refrigeration mechanism through an air pipe. The docking cover 61 is in contact with the side wall of the spiral conveyor mesh belt 3. The side wall of the spiral conveyor mesh belt 3 is provided with an air inlet 7 connected to the installation cavity. When the spiral conveyor mesh belt 3 moves, it will drive the installation cavity, the air inlet 7 and the anti-leakage component thereon to move. When the air inlet 7 moves to correspond to the docking cover 61, that is, when the docking cover 61 covers the air inlet 7, the docking cover 61 will be connected to the installation cavity. A magnetic part 62 magnetically connected to the anti-leakage component is provided in the docking cover 61. The magnetic part 62 can be a magnetic ring. The magnetic part 62 will enable the anti-leakage component to release the blockage of the through hole 52, so that the cold air can enter the cold air transmission channel through the docking cover 61, the air inlet 7, the installation cavity and the through hole 52, and then be transmitted to the surface of the spiral conveyor mesh belt 3 to freeze the dumplings on the spiral conveyor mesh belt 3.

[0036] Specifically, the magnetic member 62 is fixedly connected to the docking cover 61. When the magnetic member 62 magnetically attracts the anti-leakage component, the magnetic member 62 will be subjected to a force in the direction of the anti-leakage component, and drive the docking cover 61, with a tendency to move in the direction of the anti-leakage component, so that the docking cover 61 is tightly pressed against the side wall of the spiral conveyor mesh belt 3, thereby improving the cold air transmission effect.

[0037] Specifically, a positioning and pressing belt assembly 8 is provided on the edge of the conveying surface of the spiral conveyor mesh belt 3 away from the center of the spiral frame body 2. The positioning and pressing belt assembly 8 is connected to the supporting frame body 1 to play a positioning role to prevent the edge of the spiral conveyor mesh belt 3 from flipping up or tilting up during the transmission process of the spiral conveyor mesh belt 3, causing deviations in the docking between the docking drive switch 6 and the cold air transmission channel and the anti-leakage assembly.

[0038] Specifically, the positioning and pressing belt assembly 8 includes tooth blocks 81 that are evenly fixed to the conveying surface of the spiral conveyor mesh belt 3, and teeth are formed between a plurality of tooth blocks 81. A rotating gear 82 is provided on the support frame 1, and the gear 82 is meshed with the teeth so that the gear 82 is pressed on the tooth blocks 81 to prevent the edge of the spiral conveyor mesh belt 3 from flipping up or tilting. The friction transmission is converted into rolling rotation by the coordination of the set gear 82 and the teeth formed by a plurality of tooth blocks 81, thereby causing damage to the spiral conveyor mesh belt 3.

[0039] Specifically, the conveying surface of the spiral conveyor mesh belt is provided with multiple groups of cold air output ports 4, and each group of the cold air output ports 4 is connected one by one with the cold air transmission channel, so that the cold air can be evenly dispersed on the spiral conveyor mesh belt 3 and move with the spiral conveyor mesh belt 3, so that the cold air can continuously freeze the dumplings on the spiral conveyor mesh belt 3, thereby reducing the freezing time and improving the freezing efficiency.

[0040] Working principle:

[0041] When in use, the driving motor drives the spiral conveyor mesh belt 3 to rotate through the central drum, so that the spiral conveyor mesh belt 3 makes a spiral ascending motion along the spiral trajectory of the spiral frame 2. When the spiral conveyor mesh belt 3 moves, the cold air transmission channel will move synchronously. When the air inlet 7 moves to correspond to the docking cover 61, that is, when the docking cover 61 covers the air inlet 7, the docking cover 61 will be connected to the installation cavity, and the magnetic part 62 will move to the end close to the docking drive switch 6 through the magnetic control blocking ball 53, release the blockage of the through hole 52, so that the cold air can enter the cold air transmission channel through the docking cover 61, the air inlet 7, the installation cavity and the through hole 52, and then be evenly dispersed on the spiral conveyor mesh belt 3 through the cold air output port 4, so as to freeze the dumplings on the spiral conveyor mesh belt 3, reduce the freezing time, and improve the freezing efficiency.
