The bottom ends of the two sliding tubes 12 are fixedly sleeved with an air outlet tube 19. The bottom ends of the two air outlet tubes 19 are installed with multiple interconnected hoses 43. The multiple hoses 43 are evenly arranged around the circumference. The bottom ends of the multiple hoses 43 are fixedly installed with interconnected blow tubes 37.

Two adjusting mechanisms are installed on the side of the air outlet tube 19, and the two adjusting mechanisms are installed in conjunction with the swing mechanism.

[0024] By means of the above structure: two fans 9 and two refrigerators 14 are started, so that cold air is sent into the sliding tube 12 through the L-shaped tube 13, and is sent into the blow tube 37 through the air outlet 19 and multiple hoses 43, and is sprayed out through multiple blow tubes 37, so that the food is quickly frozen. The blow tube 37 can be moved up and down by the moving mechanism to cool foods at different heights at close range.

[0025] like Figure 1 and Figure 2 As shown, the spiral conveying mechanism includes a mesh belt 8, two frames 2 are fixedly installed on the inner wall of the bottom side of the cold storage 1, and the interiors of the two frames 2 are fixedly connected with spiral tracks 3, one of which is spirally arranged upward, and the other spiral track 3 is spirally arranged downward, the mesh belt 8 is connected end to end and rolls along the two spiral tracks 3 in sequence, and two driving motors 4 are fixedly installed at the bottom of the cold storage 1, and the output ends of the two driving motors 4 both penetrate the inner wall of the bottom side of the cold storage 1 and are fixedly installed with rolling cage frames 5, and the two spiral tracks 3 are respectively installed in cooperation with the two rolling cage frames 5; the spiral conveying mechanism also includes two mounting frames 6, and conveying rollers are rotatably installed in the two mounting frames 6, and material holes are opened on the inner walls on both sides of the cold storage 1, and the mesh belt 8 is tensioned on the two conveying rollers, and the sides of the two mounting frames 6 are fixedly installed with rotating motors 7, and the output shafts of the two rotating motors 7 are fixedly connected to the side center positions of the two conveying rollers.

[0026] When in use, food is placed on the mesh belt 8 outside the cold storage 1 , and the two rotating motors 7 and the two driving motors 4 are started, so that the mesh belt 8 rotates, thereby delivering the food into the cold storage 1 .

[0027] The moving mechanism includes a servo motor 17 fixedly installed on the top of the cold storage 1. The output end of the servo motor 17 passes through the top inner wall of the cold storage 1 and is fixedly installed with a screw rod 15. A guide sleeve 16 is threadedly sleeved on the screw rod 15. A connecting rod 18 is fixedly installed on the side of the guide sleeve 16. The end of the connecting rod 18 away from the guide sleeve 16 is fixedly connected to the side of the sliding tube 12.

[0028] In this embodiment, the servo motor 17 is started, and the output end of the servo motor 17 rotates to drive the screw rod 15 to rotate clockwise. The screw rod 15 rotates clockwise to drive the guide sleeve 16 to move downward, thereby causing the connecting rod 18, the sliding tube 12 and the air outlet tube 19 to move downward. The L-shaped tube 13 slides in the sliding tube 12, and the movement of the air outlet tube 19 drives the fixed sleeve 33, the sliding rod 34 and the pressure cylinder 35 to move, thereby driving the hair dryer 37 to move to meet the blowing needs of different positions.

[0029] The swing mechanism includes an electric telescopic rod 11 fixedly installed on the vertical side of the cold storage 1, and a moving rod 28 is fixedly installed on the output end of the electric telescopic rod 11. A round hole is opened on the inner wall of the cold storage 1, and one end of the moving rod 28 passes through the round hole and is fixedly installed with a cross bar 24. Both ends of the cross bar 24 are fixedly installed with vertically arranged rectangular rods 29, and sliders 27 are slidably sleeved on the two rectangular rods 29. The sides of the two sliders 27 that are away from each other are rotatably installed with upper rotating rods 26, and the bottom ends of the two upper rotating rods 26 are rotatably installed with connecting blocks 23. The bottoms of the two connecting blocks 23 are fixedly installed with sliding rings 22 slidably sleeved on the air outlet 19, and the air outlet 19 is slidably sleeved with an adjusting ring 44, and the side of the adjusting ring 44 is matched with two adjusting mechanisms. The sliding ring 22 and the adjusting ring 44 are installed together, and a plurality of swinging components are installed at the bottom of the sliding ring 22 and the top of the adjusting ring 44, and the plurality of swinging components are respectively installed in cooperation with a plurality of hair dryers 37; the swinging component comprises a U-shaped rod 42 fixedly installed at the bottom of the sliding ring 22, and the two bottom ends of the U-shaped rod 42 are fixedly installed with extrusion frames 39, and the top of the adjusting ring 44 is fixedly installed with a mounting block 41, and the top, bottom and side of the mounting block 41 are provided with a rotating groove, and a swinging rod 38 is rotatably installed in the rotating groove, and the swinging rod 38 is tilted downward, and the bottom end of the swinging rod 38 is fixedly installed on the top of the hair dryer 37, and the two sides of the swinging rod 38 are fixedly installed with extrusion cylinders 40, and the ends of the two extrusion cylinders 40 that are away from each other respectively pass through the two extrusion frames 39.

[0030] In this embodiment, the reciprocating movement of the sliding ring 22 drives the multiple U-shaped rods 42 to move reciprocatingly, thereby causing the multiple extrusion frames 39 to move reciprocatingly. The movement of the multiple extrusion frames 39 pulls the multiple extrusion cylinders 40 to rotate reciprocatingly, thereby causing the multiple swing rods 38 and the multiple hair dryers 37 to rotate reciprocatingly, and the multiple hair dryers 37 swing back and forth to blow air.

[0031] The swing mechanism also includes a fixed ring 30 fixedly sleeved on the air outlet tube 19, a plurality of sliding holes are opened on the top of the fixed ring 30, guide rods 32 are slidably installed in the plurality of sliding holes, the bottom ends of the plurality of guide rods 32 are fixedly installed on the top of the sliding ring 22, springs 31 are sleeved on the plurality of guide rods 32, the top ends of the plurality of springs 31 are fixedly installed on the bottom of the fixed ring 30, the bottom ends of the plurality of springs 31 are fixedly installed on the top of the sliding ring 22, and telescopic rods 25 are fixedly installed on the sides of the two sliders 27 away from the moving rod 28, and the telescopic ends of the two telescopic rods 25 are fixedly installed on the sides of the fixed ring 30.

[0032] In this embodiment, the electric telescopic rod 11 is started to cause its output end to retract and extend, thereby causing the moving rod 28 to reciprocate backward and forward, thereby causing the cross bar 24 and the two rectangular rods 29 to reciprocate. The movement of the two rectangular rods 29 causes the two sliders 27 to reciprocate, thereby causing the two telescopic rods 25 to reciprocate and extend. Since the height of the slider 27 is limited by the telescopic rod 25 to be consistent with the fixed ring 30, when the slider 27 is away from the air outlet 19, the spring 31 is in a deformed state. Under the action of the spring 31, the sliding ring 22 moves upward, thereby causing the upper rotating rod 26 to rotate. When the slider 27 approaches the air outlet 19, the slider 27 squeezes the upper rotating rod 26 so that the upper rotating rod 26 rotates in the opposite direction, thereby pushing the sliding ring 22 to move downward, thereby causing the spring 31 to deform, thereby causing the sliding ring 22 to reciprocate up and down.

[0033] The adjustment mechanism includes a fixed plate 20 fixedly installed on the inner wall of the bottom side of the cold storage 1, and an inclined hole 21 is opened on the side of the fixed plate 20. Two fixed sleeves 33 are fixedly installed on the side of the air outlet tube 19, and sliding rods 34 are slidably installed in the two fixed sleeves 33. A pressure cylinder 35 is fixedly installed at one end of the two sliding rods 34 away from the air outlet tube 19, and one end of the pressure cylinder 35 passes through the inclined hole 21. Both ends of the pressure cylinder 35 are rotatably sleeved with lower rotating rods 36, and the bottom ends of the two lower rotating rods 36 are rotatably installed on the bottom of the adjustment ring 44.

[0034] In the present embodiment, during the movement of the air outlet cylinder 19, the fixed sleeve 33, the sliding rod 34 and the pressure cylinder 35 move downward, the pressure cylinder 35 slides in the inclined hole 21, and the inner wall of the inclined hole 21 squeezes the pressure cylinder 35 so that the pressure cylinder 35 gradually approaches the air outlet cylinder 19, thereby causing the lower rotating rod 36 to rotate relative to the air outlet cylinder 19. The rotation of the lower rotating rod 36 drives the adjusting ring 44 to move downward, thereby causing the multiple mounting blocks 41 to move downward, and the movement of the multiple mounting blocks 41 causes the multiple swinging rods 38 and the multiple blow cylinders 37 to rotate, thereby adjusting the swing range of the blow cylinder 37. When the air outlet cylinder 19 reaches the lower position of the spiral track 3, the initial position of the blow cylinder 37 is in a horizontal state, and it swings upward from the horizontal during swinging, so that after adjusting to different positions, the food aligned in the direction of the spiral track 3 can still be blown evenly.

[0035] The distance between the top inner wall of the inclined hole 21 and the central axis of the air outlet tube 19 is greater than the distance between the bottom inner wall of the inclined hole 21 and the central axis of the air outlet tube 19. The advantage of this arrangement is that when the pressure cylinder 35 moves downward, it will be squeezed by the inclined hole 21 and approach the air outlet tube 19, so that the swing direction of the bottom of the hair dryer 37 can be adjusted. The height of the inclined hole 21 is greater than the length of the screw rod 15. The advantage of this arrangement is that during the rotation of the screw rod 15, the pressure cylinder 35 will not move out of the inclined hole 21. There is a gap between the side of the extrusion cylinder 40 and the inner walls of the two sides of the extrusion frame 39. The length of the L-shaped tube 13 in the sliding tube 12 is greater than the length of the screw rod 15. The advantage of this arrangement is that during the rotation of the screw rod 15, the sliding tube 12 and the L-shaped tube 13 will not be separated, which is convenient for air intake.

[0036] like Figure 1 As shown, four supporting feet are fixedly installed at the bottom of the cold storage 1, and the height of the four supporting feet is greater than the height of the driving motor 4. The supporting feet are arranged to support the cold storage 1.

[0037] The working principle and use process of the present invention are as follows: when in use, food is placed on the mesh belt 8 located outside the cold storage 1, and two rotating motors 7 and two driving motors 4 are started, so that the mesh belt 8 rotates, thereby sending the food into the cold storage 1. At the same time, two fans 9 and two refrigerators 14 are started, so that cold air is sent into the sliding pipe 12 through the L-shaped pipe 13, and sent into the blowing cylinder 37 through the air outlet cylinder 19 and multiple hoses 43, and sprayed out through multiple blowing cylinders 37, thereby quickly freezing the food; At the same time, the electric telescopic rod 11 is started to make its output end contract and extend, so that the moving rod 28 reciprocates backward and forward, and then the cross bar 24 and the two rectangular rods 29 reciprocate. The movement of the two rectangular rods 29 makes the two sliders 27 reciprocate, and then the two telescopic rods 25 reciprocate and extend. Since the height of the slider 27 is limited by the telescopic rod 25 to be consistent with the fixed ring 30, when the slider 27 is away from the air outlet 19, the spring 31 is in a deformed state. Under the action of the spring 31, the sliding ring 22 moves upward, so that the upper rotating rod 26 rotates. When the slider 27 approaches the air outlet 19, the slider 27 squeezes the upper rotating rod 26 so that the upper rotating rod 26 rotates in the opposite direction, thereby pushing the sliding ring 22 to move downward, so that the spring 31 is deformed, so that the sliding ring 22 reciprocates up and down; The reciprocating movement of the sliding ring 22 drives the multiple U-shaped rods 42 to reciprocate, thereby causing the multiple extrusion frames 39 to reciprocate, and the multiple extrusion frames 39 move to pull the multiple extrusion cylinders 40 to reciprocate, thereby causing the multiple swinging rods 38 and the multiple hair dryers 37 to reciprocate, and the multiple hair dryers 37 swing back and forth to blow air, and when located at the upper position, the swing range of the hair dryer 37 is from swinging downward to a horizontal position; When the food at different positions needs to be cooled uniformly, the servo motor 17 is started, and the output end of the servo motor 17 rotates to drive the screw rod 15 to rotate clockwise, and the screw rod 15 rotates clockwise to drive the guide sleeve 16 to move downward, thereby causing the connecting rod 18, the sliding tube 12 and the air outlet cylinder 19 to move downward, and the L-shaped tube 13 slides in the sliding tube 12, and the air outlet cylinder 19 moves to drive the fixed sleeve 33, the sliding rod 34 and the pressure cylinder 35 to move, and the pressure cylinder 35 slides in the inclined hole 21, and the inner wall of the inclined hole 21 squeezes the pressure cylinder 35 so that the pressure cylinder 35 gradually approaches the air outlet cylinder 19, so that the lower rotating rod 36 rotates relative to the air outlet cylinder 19, and the lower rotating rod 36 rotates relative to the air outlet cylinder 19. The rotation of the rotating rod 36 drives the adjusting ring 44 to move downward, thereby causing the multiple mounting blocks 41 to move downward. The movement of the multiple mounting blocks 41 causes the multiple swinging rods 38 and the multiple hair dryers 37 to rotate, thereby adjusting the swing range of the hair dryer 37. When the air outlet tube 19 reaches the lower position of the spiral track 3, the initial position of the hair dryer 37 is in a horizontal state, and it swings upward from the horizontal during the swing. Then, the output end of the servo motor 17 drives the lead screw 15 to rotate counterclockwise, causing the guide sleeve 16 to move upward, and continuing to drive the hair dryer 37 to move upward. No matter how the hair dryer 37 moves, its swing range can still be used to evenly blow air to the food in the direction of the spiral track 3.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the above disclosed technical contents to change or modify them into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
